The vertical-shaft 3D wind-mill electricity generator comprises blades and electricity generator and has high single unit output power not affected by the dirction of wind. The rotating shaft is perpendicular to the ground, and the several groups of bag-shaped blades are installed successively. No matter what direction the wind may be in, there are always at least one group of blades accepts wind for rapid rotation while the others exhaust wind. The present invention is superior to traditional turbine-type wind-mill electricity generator and the blade number may be determined based on the required power flexibly. |
