Background technology

Wind electricity blade is generally divided into housing, crossbeam and web according to the function of parts and feature, in the time that traditional megawatt wind-power blade is made, generally first preformed web and blade upper and lower casing, the leading edge of lower house or upper shell and trailing edge prefabricated for the interior bonding flange of bonding matched moulds, then use structure glue respectively web, blade upper shell and blade lower house to be bonded together, after solidifying, the burr of blade front and rear edge are cleaned out, then carry out respectively outer reinforcement at the cemented side seam of the bonding leading edge of upper-lower casing and trailing edge, reinforce adhesive effect. After the glass fabric of outer reinforcement solidifies, then blade is carried out to further profile correction, and spray paint, finally complete the manufacture of blade.

In order better to obtain wind energy, blade of wind-driven generator need to meet certain aerodynamic configuration condition. While adopting existing technology to manufacture blade, because of structural requirement, after vane mold matching, need to carry out outer reinforcement in blade front and rear edge matched moulds seam position, when reinforcement, glass fibre laying has been destroyed the aerodynamic configuration that has changed blade initial design, after outer reinforcement finishes, need to reuse the materials such as polyurethane putty the aerofoil profile of blade front and rear edge is revised to meeting designing requirement. The use that relates to multiple material outside blade in reinforcement and aerofoil profile makeover process with solidify, need to carry out reprocessabilty and wait for and solidifying blade, especially in the winter time, outer reinforcement and repair type problem of solidification blade integral manufacturing schedule is caused to serious impact.
