Example Embodiment
[0017] In an embodiment, a piezoelectric wind energy collection device with self-adjustable wind speed and openable at low wind speed. The working principle of the present invention is as follows: firstly, wind from different directions enters the intensive air duct, and after the feedback airbag adjusts the rectifying device, the intensive air duct and the umbrella-shaped rectifying device are jointly constrained to increase the speed and point to the wind of the edge of the fan impeller, the same The wind speed points towards the edge of the fan impeller relative to the center of the fan to make it easier to turn on the fan, so that the fan is turned on at a lower wind speed, and then the wind energy is converted into the mechanical energy of the fan. The piezoelectric cantilever beam with phosphor bronze as the substrate is fixed around the fan. The piezoelectric cantilever beam adopts the dual crystal mode. The cantilever beam is triangular piezoelectric cantilever beam with...
