Blade structure for vertical wind power generator

摘要

The present invention relates to a blade structure for a vertical wind power generator. An inner body of the blade structure is formed as a low density foaming body, and an outer body is formed as a high density foaming body. So, the weight of the blade structure is remarkably reduced and is light. Also, the blade structure can rotate at high speed and is not damaged even in the rotation at the high speed. The blade structure includes flexibility and shock absorption performance even if the blade structure has high strength. The blade structure prevents air sound, generated when the blade structure passes in the air, from being largely generated. The blade structure for a vertical wind power generator can improve mechanical strength thereof and can maximize stability of a product to endure a strong wind force by having the flexibility and the shock absorption performance of a material. A folding unit folded to the inner side is formed at upper and lower ends of the blade structure, and rotation efficiency of the blade structure is improved. Also, the vertical length of the blade structure can be variously manufactured.
