The wind power and self-powered power generation device 100 of the present invention may be set at a fixed point or may be mounted on a moving object such as a traffic vehicle. As shown in Fig. 2, the blade 11 faces the front of the traffic carrier, and the higher the speed at which the traffic carrier advances, the greater the wind force carried by the blade 11, and the higher the rotational speed.

In the present embodiment, the blade 11 of the blade assembly 1 is a scroll blade. In other embodiments, the blade 11 can also be a helical blade, a spherical blade, or a louvered blade. The rotational movement of the blade 11 is with the drive shaft 12 as the axis of rotation. The drive shaft 12 is a single rotating shaft that drives the blade 11, the first generator 2, the motor 3, and the second generator 41 to transmit the power of the blade 11 to the first generator 2. In other embodiments, the transmission shaft 12 can also be a plurality of rotating shafts connected by gears, pulleys, transmissions, etc., and can also transmit the power of the blades 11 to the first generator 2.

In detail, the blade 11 carries the wind and rotates. When the rotational speed of the blade 11 reaches a certain value, the first generator 2 can be driven through the transmission shaft 12 to cause the first generator 2 to generate electricity.
