Abstract

The invention discloses a large speed-increasing ratio wind-force piezoelectric power generation device, which comprises wind rotor blades, an input shaft, a speed-increasing mechanism, an output shaft, a cylindrical cam, a linear motion cam and a piezoelectric power generation assembly; The speed mechanism transmits power; the output shaft drives the linear motion cam through the cylindrical cam, and the linear motion cam drives the guide rod of the piezoelectric power generation component to move up and down reciprocatingly, thereby realizing the deformation of the piezoelectric vibrator on the guide rod to generate electric energy. The invention forms a speed-up transmission with a large transmission ratio through the speed-up mechanism, which effectively improves the excitation frequency and can generate higher electric energy even when the wind force is low; the deformation of the piezoelectric vibrator will not produce strong mechanical noise; only The arrangement of the piezoelectric vibrators on the guide rod can be changed by changing the number of notches on the guide rod and the access ports of the piezoelectric vibrators on the support frame, and the piezoelectric power generation components including the guide rod and piezoelectric vibrators can also be set as required number to meet the power output requirements.

Description

technical field [0001] The invention relates to a device for generating electricity by using wind force to drive a piezoelectric material, in particular to a wind-driven piezoelectric generating device with a large speed-up ratio. Background technique [0002] Energy sources such as solar energy, wind energy, vibration energy, and temperature difference energy exist widely in nature, and micro energy devices based on such clean energy have important application prospects. Vibration energy exists in various forms, and collecting vibration energy as micro-energy is an effective method for generating environmental energy. Among them, the piezoelectric vibration generator has become the focus of research in the field of vibration power generation at home and abroad due to its advantages of high energy conversion efficiency, simple structure, no electromagnetic interference, easy miniaturization of the overall structure, and easy integration. An important way of powering MEMS de...
