Document Type and Number:
WIPO Patent Application WO/2021/129829
Kind Code:
A1
Abstract:
Disclosed are a prefabricated member of a blade root of a wind power blade, a blade root component, and a blade and a manufacturing method therefor. The manufacturing method comprises: manufacturing several prefabricated members of a blade root of a wind power blade; laying outer layer fiber fabric (7) in a blade root mold, placing the several prefabricated members on the outer layer fiber fabric (7), and joining adjacent prefabricated members; laying inner layer fiber fabric (8) on the joined prefabricated members; and carrying out pouring into the blade root mold to form the blade root. Part of the laying layers is prefabricated, assembled and formed, and then placed into the blade root mold for integral molding together with the remaining laying layers. A production method and mold for a blade root assembly of a wind power blade are further disclosed. An upper-layer substrate (3), a lower-layer substrate (2), and an embedded part (1), which are prefabricated, are placed in the mold and assembled and molded together by means of heating and curing without integral pouring, such that the difficulty and time of later pouring and molding can be reduced, the defect rate can be reduced, and the overall height can be ensured to be consistent.
