As improvement, said link comprises and is up and down the connecting ring that distributes more than one that said connecting ring connects said connecting sheet successively, said connecting sheet and connecting ring formation cage-shaped structure.
As improvement, the cross section of said blade is water droplet shape small in ends broad in the middle, and a wherein end wherein small in ends is a nose circle, and the other end is most advanced and sophisticated.The blade of this kind shape is high to utilization ratio of wind energy.
As improvement, the shape of cross section of said support arm is similar with said leaf cross-section shape.The blade rotation drives support arm and rotates together, in rotary course, can not influence the force structure of whole blade for making support arm, and the shape of cross section of design support arm is similar with the shape of cross section of blade.
As improvement, be provided with drag-line between said link and the said support arm and be connected, the effect of drag-line is the vibration that reduces blade.
The beneficial effect that the utility model is compared with prior art brought is:
Be provided with the support arm more than between blade and the link, the design of support arm makes the windward side of blade stressed better, and the structure of blade has bigger intensity; Be provided with drag-line between blade and the support arm and be connected, the effect of drag-line is the vibration that reduces blade; The design of mouse cage can reduce the degreeof tortuosity of blade in rotary course.
