Specifically, when the blade B21 is bent to form a manual windmill shape, the root portion 2101 and the end portion 2103 have a certain pitch in the axial direction. After being arranged in this way, the plurality of blades B21 can be wrapped to form an intermediate cavity after being bent. The third vane structure 30 is disposed in the intermediate cavity and is sleeved on the rotating shaft 1.

That is, when wind blows from the front end to the rear end of the rotating shaft 1, the wind direction is changed when the wind contacts the corresponding blade structure; the changed wind still allows the next stage of blade structure to be acted on, and the wind energy is fully utilized. When the wind power generation device is used for generating electricity, the utilization rate of wind energy is fully improved.
