Abstract

See full text

Disclosed is a blade apparatus for wind power generation, which includes: a blade body, one end thereof being provided with a blade-root connecting portion; and a blade root assembly, including a plurality of blade root segments arranged in a circumferential direction of the blade body to form a body of revolution, each blade root segment being detachably connected to a corresponding portion of the blade-root connecting portion. The blade root assembly with a plurality of blade root segments is adopted, so that the dimension of a single blade root segment is greatly reduced, thus effectively reducing the difficulties in manufacture and transportation. Meanwhile, the overall dimension of the blade root assembly can be further increased to match with a larger blade body, which is beneficial to further improve the swept area of blade and generated output of wind power generation device.
