Abstract

The invention provides a system for driving a piezoelectric material to generate electricity by using wind energy, which comprises a wind-powered rotating device and a box body, wherein a transmission device, an alarm, spring pieces of which a plurality of surfaces are provided with piezoelectric patches, a DC regulator, an anti-charge diode, a storage battery, a controller and an inverter are arranged in the box body. The system drives the alarm to generate the voice with a certain sound intensity by using reproducible, clean and pollution-free wind energy, the piezoelectric patches with high energy density and high power generation efficiency are driven through the sound to carry out vibration power generation, thus the system improves the energy efficiency, saves energy and protects atmospheric environment.

Description

technical field [0001] The invention relates to a generating device, in particular to a system for generating electricity by using wind energy to drive piezoelectric materials. Background technique [0002] The piezoelectric effect was discovered by the Curie brothers when they studied quartz more than 100 years ago. The principle is that if a pressure is applied to the piezoelectric material, it will generate a potential difference, which is called the positive piezoelectric effect; otherwise, a mechanical voltage will be generated. Stress is called the inverse piezoelectric effect. In real life, piezoelectric materials have the function of conversion and inverse conversion between mechanical energy and electrical energy. Piezoelectric material power generation is characterized by durability, cleanliness, and maintenance-free. It has ultra-high energy density, and its peak energy density can reach 100-10000Kw / Kg, while traditional electromagnetic induction generators have ...
