WIPO Patent Application WO/2022/007610
Kind Code:
A1
Abstract:
Disclosed in the present invention are a lightweight main beam for a wind power blade having a concave structure and manufacturing, a main beam structure combination, and the wind power blade and a manufacturing method therefor. The lightweight main beam for the wind power blade having the concave structure is integrally groove-shaped, and comprises support portions located on two wings of the lightweight main beam and a middle connecting portion for connecting the two support portions. The manufacturing method comprises: laying a reinforcement of the middle connecting portion and a support material of the support portions, and filling resin. The main beam structure combination comprises a web plate and the lightweight main beam; the two ends of the web plate are respectively connected to a pressure surface lightweight main beam and a suction surface lightweight main beam by means of positioning and matching structures. Further disclosed are the wind power blade comprising the lightweight main beam structure combination and the manufacturing method for the wind power blade. According to the present invention, by integrating various factors, the weight of the wind power blade is reduced, the material utilization rate of the wind power blade is increased, and the light weight of the wind power blade is achieved.
