PURPOSE: A blade structure for wind power generation having a pocket-shaped blade and a darrieus-type rotary body therewith are provided to improve wind power generation efficiency by minimizing the rotation resistance of a rotary shaft. CONSTITUTION: A blade structure for wind power generation having a pocket-shaped blade comprises a support frame and pocket-shaped blades(130). The pocket-shaped blades are fixed to the support frame. Each pocket-shaped blade comprises a mounting frame and a flexible blade membrane. One end of the mounting frame has a concave mounting space, and the other end has a linear corner. The flexible blade membrane is welded in the corners of the mounting frame except one end of the mounting frame. |
