According to Fig. 1 a to Fig. 1 c it can be seen that this TRT farther includes: body 16, wind-driven part
12, rotary shaft 13, drive disk assembly 14, suppresses assembly 15 and friction generator 11.Wherein wind drive
Parts 12, drive disk assembly 14, the quantity suppressing assembly 15 and friction generator 11 can be all multiple.
Wherein, body 16 is semi-enclosed cylindrical body, including diapire and sidewall；It is fixed with on the sidewall of body 16
At least one friction generator 11 and at least one corresponding with friction generator 11 suppress assembly 15,
Wherein, each friction generator 11 is fixed by the sidewall of the first side surface with body 16, suppresses assembly
15 extrude when the active force of driven parts 14 or the second side surface of release friction generator 11；
The diapire of body 16 is flexibly connected with the bottom of rotary shaft 13, and rotary shaft 13 is parallel to the sidewall of body 16,
And the top of rotary shaft 13 stretches out from the inside of body 16；Wind-driven part 12 is installed in rotary shaft 13
Top, for when by wind-force effect drive rotary shaft 13 rotate；First end of drive disk assembly 14 is
Fixing end, this fixing end is installed in the middle part of rotary shaft 13, and the second end of drive disk assembly 14 is free end,
This free end can produce active force when rotary shaft 13 rotates to suppressing assembly 15.
Alternatively, the bottom of rotary shaft 13 is flexibly connected with the centre of the diapire of body 16.So,
When the drive disk assembly quantity in rotary shaft 13 is multiple, and the quantity of the friction generator on organism sidewall is also
For time multiple, the arbitrary drive disk assembly in rotary shaft 13 is when turning near arbitrary friction generator, logical
Cross that to suppress the extruding degree that this friction generator caused by assembly the most equal, it is possible to reach preferably to send out
Electricity effect.But, it will be appreciated to those of skill in the art that in a practical situation, rotary shaft 13
The centre of the diapire of body 16 can also be deviateed in bottom, and this is not limited by the present invention.
Company each several part in this wind power generation system between is discussed in detail below in conjunction with Fig. 1 a to Fig. 1 c
Connect relation:
Wherein, body 16 can be cylinder, it is also possible to be prism body.Alternatively, body 16
For semi-enclosed regular prism body, and, each sidewall of this regular prism body can be respectively provided with one
Individual friction generator and one suppress assembly.Such as, in Fig. 1 a to Fig. 1 c, body 16 is positive six
Prism body, it has six sidewalls and a diapire, is respectively provided with a triboelectricity on each sidewall
Machine 11 and one suppress assembly 15.In a practical situation, body 16 can also be regular triangular prism, just
The shapes such as quadrangular, the shape of body 16 is not limited by the present invention.
The effect of body 16 mainly has two: first, fixed friction electromotor and be used for compressing friction and send out
Motor suppress assembly, in order to realize this effect, body 16 needs have multiple sidewall；Second, Gu
Determining rotary shaft 13, make rotary shaft 13 to rotate freely, in order to realize this effect, body 16 needs
There is one for the diapire being flexibly connected rotary shaft 13.It addition, in order to utilize wind energy to drive body
Rotary shaft within 16 rotates, and this body 16 must also be semi-enclosed, and such as, this body 16 is permissible
There is no roof, or, roof has opening.
After having introduced the shape of body 16, specifically introduce rubbing of being fixedly installed on the sidewall of body 16
Wipe electromotor 11 and suppress assembly 15.Wherein, friction generator 11 has two relative side surfaces,
Being respectively the first side surface and the second side surface, each friction generator 11 is fixed on by the first side surface
On the sidewall of body 16.Suppress assembly 15 and be fixed on adjacent with the second side surface of friction generator 11
On position.
Fixing on the sidewall 160 of body 16 two kinds that suppress assembly are specifically introduced referring to Fig. 2 a
Implementation.As shown in Figure 2 a, in the first implementation suppressing assembly, this suppresses assembly bag
Include: fixed component 151, snap parts 152 and reset components 153.Wherein, fixed component 151 is fixed
On the sidewall 160 of body, it is securely seated between organism sidewall for assembly will be suppressed, such as, Gu
Limiting-members 151 can be realized by the stator of an intermediate projections, and by devices such as screws, this is solid
Stator is fixed on organism sidewall 160, and wherein, the part that stator is protruding is primarily to accommodate fixing
Friction generator 11 on organism sidewall 160, the height of projection of this bossing should be at least above friction
The thickness of electromotor 11, to prevent from friction generator 11 causes under nonextruding state unnecessary squeezing
Pressure.Snap parts 152 is flexibly connected with fixed component 151, for the extruding at driven parts 14
Time contact the second side surface of extrusion friction electromotor 11, for example, it is possible to convex in fixed component 151
The centre position playing part arranges a circular hole, makes snap parts 152 through this circular hole and fixed component 151
Being flexibly connected, specifically, snap parts 152 includes three parts: Part I is for being positioned at fixed component 151
The part within bossing, this part is usually flat sheet-like, and concrete shape can be with triboelectricity
The shape of machine 11 is consistent；Part II is through the connecting shaft at the circular hole in fixed component 151, is used for
Connect Part I and Part III；Part III is positioned at the outside of the bossing of fixed component 151,
For contacting with drive disk assembly 14.Reset components 153 makes the snap parts 152 can be when not compact
Return to initial position.Reset components 153 can be realized by spring.For example, it is possible to spring is arranged
In the outside of the bossing of fixed component 151, and the connecting shaft being close to snap parts 152 is configured,
Therefore, one end of this spring props up the inner side of the Part III of snap parts 152, and the other end props up fixed part
The outside of the bossing of part 151 such that it is able to play reset response.
In the first implementation introduced above, suppress assembly by drive disk assembly 14 and snap parts
Directly contact between 152 realizes the drive disk assembly 14 extruding to snap parts 153, and then promotes to rub
Wiping electromotor deforms upon.As can be seen here, in the first implementation, drive disk assembly 14 is to suppressing group
The active force of part is the extruding force produced owing to directly contacting.
In above-mentioned Fig. 1 a, Fig. 1 b and Fig. 1 c, depict and suppress assembly by the first realization above-mentioned
When mode realizes, the profile of corresponding TRT, top view and 3-D effect simulation drawing.
Alternatively, suppressing assembly can also be realized by the second implementation, the second implementation and the
The structure of a kind of implementation is essentially identical, and difference is: in the second implementation, can be by passing
Magnetic force between dynamic component 14 and snap parts 152 repels each other effect to realize drive disk assembly 14 to snap parts
The extruding of 153, therefore, both can directly contact between drive disk assembly 14 with snap parts 152, it is possible to
To be not directly contacted with.Specifically, in order to achieve this it is needed make drive disk assembly 14 and snap parts 152
It is respectively provided with magnetic, and the magnetic phase that the magnetic that had of drive disk assembly 14 is had with snap parts 152
With, thus produce mutually exclusive active force when the two is close to each other, it may be assumed that in the second implementation,
The active force suppressing assembly is squeezed by drive disk assembly 14 mainly due to magnetic force produced by principle of same-sex repulsion
Pressure.When implementing, first have to make the second end of drive disk assembly 14 to have magnetic.To achieve it,
Both can be at one block of Magnet of the second end additional of drive disk assembly 14, it is also possible to directly to drive disk assembly 14
The second end carry out magnetization treatment.Secondly, suppressing the snap parts 152 in assembly is magnetic snap parts.
The magnetic phase that second end of the magnetic being had due to this magnetic snap parts and drive disk assembly 14 is had
Instead, so when drive disk assembly 14 rotates in time suppressing the position of assembly with rotary shaft, magnetic elastic pressing part
The magnetic force extruding of the second end of the driven parts of part 14, thus contact the second of extrusion friction electromotor
Side surface.Realize when suppressing the compression of assembly by the magnetic force effect of repelling each other, due to drive disk assembly and elastic pressing part
Contact can be need not between part, therefore, it is to avoid the frictional dissipation between drive disk assembly and snap parts,
Improve service life of equipment.
When suppressing assembly and being realized by the second implementation, the profile of corresponding TRT such as figure
Shown in 1d, it can be seen that be respectively provided with magnetic owing to suppressing assembly and drive disk assembly from Fig. 1 d, therefore,
Drive disk assembly and suppress and can leave certain space between assembly, without the most directly connecing
Touch.
In the two kinds of implementations suppressing assembly described above, the drive disk assembly active force to suppressing assembly
It is extruding force.Therefore, in above two mode, suppress the initial position of elastomeric element in assembly all
The adjacent locations being positioned at the second side surface of friction generator (does not connects with the second side surface of friction generator
The position touched).When suppressing assembly and being positioned at initial position, friction generator is not compact.Correspondingly,
When suppressing the extruding force of the driven parts of assembly, snap parts contact the second of extrusion friction electromotor
Side surface, promotes friction generator to deform upon, and then produces electric current.
In addition to two kinds of implementations described above, suppress assembly and can also pass through the third implementation
Realize.In the third implementation, similar with the second implementation, it is all to utilize magneticaction to make biography
Dynamic component just can produce active force to it in the case of assembly not contacting to suppress.Difference is, the 3rd
Planting in implementation, the initial position suppressing the elastomeric element in assembly is positioned at the second side with friction generator
The position that surface contacts.Further, when suppressing assembly and being positioned at initial position, triboelectricity chance is by bullet
The extruding force of pressure assembly.Correspondingly, drive disk assembly is to suppressing the active force of assembly mainly due to there is a natural attraction between the sexes
Magnetic force produced by principle attracts (that is: drive disk assembly is contrary with the magnetic suppressing assembly), thus, at bullet
When pressing the captivation of the driven parts of assembly, the second side surface of snap parts release friction generator, make
The extruding force that friction generator is subject to disappears or reduces, thus promotes friction generator to deform upon, and then produces
Raw electric current.Suppress the concrete structure of the third mode of assembly as shown in Figure 2 b.From Fig. 2 b it can be seen that
Suppress assembly similar with first two implementation, still include fixed component 151, snap parts 152 and answer
Position parts 153.Fixed component 151 again may be by the stator of an intermediate projections and realizes.And suppress
Parts 152 include three parts equally.Difference is, the position of reset components 153 is different from Fig. 2 a:
In figure 2b, reset components 153 is arranged on the inside of the bossing of fixed component 151, therefore, is somebody's turn to do
One end of reset components 153 props up the Part I of snap parts 152, and the other end props up fixed component 151
The inner side of bossing.Under the effect of reset components, it is possible to make snap parts not by drive disk assembly
Second side surface of extrusion friction electromotor during active force, and discharge when the active force of driven parts and rub
Wipe the second side surface of electromotor, thus promote friction generator to deform upon, and then produce electric current.
The structure suppressing assembly described above is only schematically, and those skilled in the art can also be according to need
To realize this by other forms and to suppress assembly, as long as being capable of compressing the function of friction generator i.e.
Can.
It follows that introduce the rotary shaft 13 being positioned within body 16 and be installed in rotary shaft 13
Wind-driven part 12 and drive disk assembly 14.
The bottom of rotary shaft 13 is arranged on the centre of the diapire of body 16.Specifically, rotary shaft 13
Bottom and the diapire of body 16 between be flexibly connected.Flexible connection has following 2 effects: first
First, owing to there is annexation between bottom and the body diapire of rotary shaft 13, it may thereby be ensured that rotate
The entirety of axle 13 is fixing relative to the position of body, and such as, the entirety of rotary shaft 13 can be parallel to
The vertical direction (being i.e. parallel to the sidewall of body) of body；Secondly as the bottom of rotary shaft 13 and body
It is to be flexibly connected, it may thereby be ensured that rotary shaft 13 can rotate freely around its axle center between diapire.
It addition, the top of rotary shaft 13 is stretched out in body 16, thus it is positioned at the outside of body 16, for
Realizing this point, the length of rotary shaft 13 is typically greater than the height of body 16.So can make rotation
Wind-driven part on axle 13 is exposed in wind.
Next the wind-driven part 12 and drive disk assembly being installed in rotary shaft 13 is specifically introduced
14。
Wind-driven part 12 is installed in the top of rotary shaft 13, therefore, wind-driven part 12 also position
In the outside of body 16, thus rotary shaft can be driven to rotate when blowing by wind.Wind drive portion
Part 12 can be such as the parts such as vane and/or fan blade.Mainly with wind-driven part as vane in the present invention
As a example by be described, but it will be appreciated to those of skill in the art that the wind-driven part in the present invention also
It is not limited to this kind of form of vane, any portion that rotary shaft 13 can be driven when by wind-force effect to rotate
Part can serve as wind-driven part.And, the shape of vane or fan blade should be designed as being suitable for being bullied as far as possible
Stream impact and the shape that rotates, for example, it is possible to carry out with reference to shapes such as the fan blade of wind wheel, wind sticks
Design, alternatively, vane can be to be made up of semicircle empty cup.It addition, the number of wind-driven part 12
Amount can be that the angle between multiple and the most adjacent two wind-driven part is equal.Such as, wind-force drives
Dynamic component quantity is three, and the most adjacent angle between two wind-driven parts is 120 degree, such as figure
Shown in 1a to Fig. 1 c.
First end of drive disk assembly 14 is fixing end, and this fixing end is installed in the middle part of rotary shaft 13.Transmission
Second end of parts 14 is free end, and it contacts when rotary shaft 13 rotates and extrude and suppresses assembly 15.
Specifically, drive disk assembly 14 and mistake presented hereinbefore suppress assembly 15 and friction generator 11 be positioned at
In one circumferential plane, in order to when electricity generation system operates, can mutually extrude between above-mentioned each parts.Optional
Ground, drive disk assembly 14 can be realized by plectrum or cantilever beam.Certainly, the drive disk assembly in the present invention
Being not limited to plectrum and cantilever beam both forms, any can extruding when rotary shaft rotates suppresses assembly
Parts can serve as drive disk assembly.It addition, in order to improve extruding efficiency, the quantity of drive disk assembly 14
Can be multiple, when the quantity of drive disk assembly 14 is multiple, can be by two the most adjacent drive disk assemblies
Between angle be set to equal, so that extrusion time corresponding to each friction generator and dead cycle time
Distribution more equalize.
Further, in order to reduce drive disk assembly 14 with suppress assembly 15 contact time energy loss, also may be used
With the end face by the second end of drive disk assembly 14 (i.e. plectrum or cantilever beam and the one end suppressing component touch)
It is designed as circular arc end face, correspondingly, position (the i.e. bullet that assembly 15 contacts with drive disk assembly 14 will be suppressed
The Part III of snap parts 152 in pressure assembly 15) end face be also configured as circular arc end face.Contact surface
Design form for circular arc end face is possible not only to make frictional force during contact less, thus energy when reducing contact
Amount loss, and also be able to play certain cushioning effect.
And, in order to improve generating efficiency, setting can also be spaced in embodiments of the present invention on the rotating shaft
Multi-layer transmission parts, correspondingly, are also correspondingly arranged multilamellar on organism sidewall and suppress assembly and friction generator.
Wherein, each layer of drive disk assembly, suppress assembly and friction generator is positioned at same circumferential plane, constitute one
The parts that group can mutually extrude.So, when rotary shaft rotates under wind-driven part drives, permissible
Extrude more friction generator simultaneously, thus improve efficiency.
Introduce the work process of above-mentioned wind power generation system in detail below:
When wind blows the wind-driven part 12 in rotary shaft 13, wind-driven part 12 is promoted to rotate,
And then drive rotary shaft 13 to rotate.Such as, there are three wind-driven parts 12 in Figure 1b, in order to
It is convenient to describe, and the wind-driven part that will be located in left side is referred to as the first wind-driven part, will be located on right side
The wind-driven part of side is referred to as the second wind-driven part, and the wind-driven part that will be located in lower right-hand side claims
Make the 3rd wind-driven part.False wind blows from left, due to direction and the wind of the first wind-driven part
To close to parallel, therefore, wind is being perpendicular to the first wind-driven part to the pressure of the first wind-driven part
Component on Zhou Xiang is also approximately at zero.Second wind-driven part and the 3rd wind-driven part approximate with wind direction
60 degree of angles are intersected, and for the second wind-driven part, windward, the blast therefore born is maximum for its concave surface；
For the 3rd wind-driven part, its convex surface windward, owing to the detour flow of wind makes wind pressure ratio suffered by it
Two wind-driven parts are little, owing to the second wind-driven part and the 3rd wind-driven part are being perpendicular to wind-force
Pressure differential on driver part is axial, and make these three wind-driven part start to be rotated clockwise, produce
Raw circular motion.
Correspondingly, rotary shaft 13 rotates with wind-driven part 12 and rotates.Rotation along with rotary shaft 13
Turning, the drive disk assembly 14 being installed in rotary shaft 13 also rotates with.When drive disk assembly 14 rotates to bullet
Time near pressure assembly 15, start extruding and suppress assembly 15.Specifically, drive disk assembly with suppress connecing of assembly
Experienced by following two processes: a) gradually reduce process between contacting surface.This process rotates from drive disk assembly 14
Time point to the edge (the most just with suppress component touch) suppressing assembly 15 is continued until biography
Dynamic component 14 rotates to the middle part (i.e. and suppress between assembly extruding force maximum) suppressing assembly 15
Time point.In this process, drive disk assembly 14 gradually extrudes the snap parts 152 suppressing in assembly 15
The circular arc end face of Part III, cause reset components 153 to gradually reduce, and the circular arc of snap parts 152
End face starts to move to organism sidewall direction thus extrusion friction electromotor 11, when the circle of snap parts 152
When the summit of the circular arc end face of the summit of arc end face and drive disk assembly 14 coincides, suppress assembly 15 to friction
The decrement of electromotor 11 reaches maximum.B) process is gradually discharged.This process rotates from drive disk assembly 14
Time point to the middle part suppressing assembly 15 is continued until that drive disk assembly 14 leaves and suppresses assembly 15
The time point at other edge position.Summit and drive disk assembly 14 when the circular arc end face of snap parts 152
The summit of circular arc end face separate after, snap parts 152 circular arc end face in the effect of reset components 153
Under start bounce-back, thus gradually release friction generator 11, until two circular arc end faces completely disengage from.Above
Process i.e. completes once to generate electricity.Drive disk assembly 14 continuously circular motion makes above-mentioned power generation process repeatedly
Carry out.It is to be introduced, when suppressing as a example by the first implementation to suppress assembly in above process
When assembly is the second implementation, compression process is similar to therewith, and here is omitted.
It addition, in above process, owing to wind speed is the biggest, the second wind-driven part and the 3rd wind drive
Pressure differential when parts initiate is the biggest, thus the acceleration produced is the biggest, causes the rotation of rotary shaft 13
Rotary speed is the fastest, so that the rotary speed of drive disk assembly 14 increases the most accordingly.Assume in the present embodiment
Drive disk assembly quantity is three, then, in rotary course, successively compression is suppressed assembly by these three drive disk assembly.
Therefore, when wind speed reaches certain value, suppress assembly 15 and just completed described above at previous drive disk assembly
Compression process when discharging the most completely, compressed by next drive disk assembly the most at once, cause friction to be sent out
Motor is constantly subjected to suppress the compression of assembly 15 and cannot discharge, and friction generator is dependent on compressive state
And the deformation between release conditions produces electrostatic thus generates electricity, so, when friction generator is always maintained at
Then cannot effectively generate electricity when compressive state is constant, and then cause this wind power generation system cannot normal work
Make.To this, the quantity of drive disk assembly can be adjusted according to the size of wind speed.When wind speed is the biggest, reduces and pass
Dynamic component quantity, thus ensure that friction generator can discharge upon compression in time, and then guarantee that system is just
