Rotary piezoelectric power generation charger driven by wind force

Abstract

The invention belongs to the technical field of new energy, and relates to a rotary piezoelectric power generation charger driven by wind force. The rotary piezoelectric power generation charger is used for collecting wind energy in environments and converting the wind energy into electric energy. The rotary piezoelectric power generation charger comprises a rotary piezoelectric power generation assembly, an interface processing circuit and a rechargeable battery. Piezoelectric crystal layers and metal neutral layers of the rotary piezoelectric power generation assembly form piezoelectric double-crystal beams, and the piezoelectric double-crystal beams are distributed around a spindle to form a circumferential array and are fixed onto a body of a motor by the aid of fixtures. The interface processing circuit comprises a rectifier circuit, a voltage regulating circuit and a battery charging circuit. The rotary piezoelectric power generation charger has the advantages that the piezoelectric power generation charger is simple in structure and low in manufacturing cost, and is clean and pollution-free; the quantity of peripheral electronic components required by the interface processing circuit is low, a design principle of low power consumption is met, and the interface processing circuit can be integrated easily, has an over-charge and over-discharge protection function and is high in stability; the piezoelectric power generation charger is applicable to low-speed wind energy and can be used with sensor nodes.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a wind-driven rotary piezoelectric generator charger for collecting wind energy in the environment and converting it into electric energy. Background technique [0002] At present, the seriousness of the energy crisis is becoming increasingly prominent, which has caused great inconvenience to people's daily life.
