Weak multistable vibration power generation device based on rolling magnet

Abstract

The invention discloses a weak multistable vibration power generation device based on a rolling magnet. The weak multistable vibration power generation device comprises a vibration power generation device body, a rectifying, filtering and voltage stabilizing circuit and a load module which are sequentially connected through wires. The vibration power generation device comprises a rectangular section pipe, a long coil and a radial magnetization cylindrical magnet. The interior of the rectangular section pipe is of a tubular structure with a rectangular section hole cavity, and a radial magnetization cylindrical magnet capable of freely rolling in the axial direction of the rectangular section pipe is contained in the rectangular section pipe. The long coil is continuously wound on the outer wall of the rectangular section pipe along the same direction; a left end cover and a right end cover respectively cover the two ends of the rectangular section pipe, and the two ends of the rectangular section pipe are respectively fixed on the left connecting clamp and the right connecting clamp; the left and right ends of the magnet at the lower end of the rectangular-section pipe are respectively fixed at the lower parts of the left connecting clamp and the right connecting clamp; the rectifying, filtering and voltage stabilizing circuit comprises a single-phase bridge type rectifying circuit, a capacitor filtering circuit and a parallel voltage stabilizing circuit which are electrically connected in sequence; and the load module comprises a load.

Description

technical field [0001] The invention belongs to the technical field of power generation devices, and in particular relates to a weak multi-stable vibration power generation device based on rolling magnets. Background technique [0002] In recent years, in order to protect the environment, reduce the pollution of waste batteries, and reduce the cost of regular replacement of equipment batteries, environmental energy harvesting technology has attracted extensive research interest. Environmental energy harvesting is of great significance in clean production and improving energy efficiency. At present, the available energy in the environment mainly includes solar energy, wind energy, water energy, thermal energy, mechanical energy and so on. Among these available environmental energy sources, mechanical vibration energy is an ideal energy source except solar energy, wind energy, water energy and other energy sources with relatively mature development technologies. The phenomen...
