<p>A blade device comprises a shaft pipe portion (60), a circular ring portion (70) and a plurality of blades (80), wherein the circular ring portion (70) is provided with a plurality of pull rods (72) which are integrated to centralize the moment on the shaft pipe portion (60) in an interlacing and straining manner, such that each blade (80) is supported effectively between the shaft pipe portion (60) and the circular ring portion (70). The blade device, which is light in weight and better in rigidity, is effectively driven by a thrust generated by natural wind so as to generate mechanical energy. The sheet of each blade (80) is opened or closed by a driving transmission assembly, thus the blades can be effectively protected from strong wind and fully generate electricity.</p> |
