Abstract

The invention discloses a wind array type magnetic nonlinear piezoelectric power generation device, and relates to the field of electromagnetic driving and new energy utilization. The wind array typemagnetic nonlinear piezoelectric power generation device has the advantages of being simple in structure, low in cost, wide in resonance frequency band and the like. The device is composed of a generator casing, L-shaped supporting beams, linear supporting beams, ceramic piezoelectric plates, magnets, a driving shaft, bearings, fan blades and a base. The ceramic piezoelectric plates, the L-shapedsupporting beams and the magnets form L-shaped piezoelectric vibrators; the L-shaped piezoelectric vibrators and the base form a stator part of a generator; the linear supporting beams, the ceramic piezoelectric plates and the magnets form linear piezoelectric vibrators; the linear piezoelectric vibrators, the driving shaft and the blades form a rotor part of the generator; and power is input to the rotor through the blades, the rotor is driven to rotate in the stator by the power of the blades, and meanwhile, the L-shaped piezoelectric vibrators and the linear piezoelectric vibrators generatenonlinear vibration. The device is used for meeting the energy requirements of low-energy-consumption electronic products.

Description

technical field [0001] The invention belongs to the field of piezoelectric power generation, and in particular relates to a wind array type magnetic nonlinear piezoelectric power generation device. Background technique [0002] With the rapid development of the electromechanical industry, wireless sensor technologies such as micro-electromechanical systems (MEMS) and low-power embedded technologies are increasingly becoming integrated, intelligent, and miniaturized. Therefore, there is a higher demand for its energy supply industry, but because the traditional energy supply industry has been stagnant, the shortcomings of battery power supply have gradually emerged (small capacity, short life, easy to be restricted by the environment, difficult to recycle, It is easy to cause heavy metal pollution), which seriously limits the development of wireless sensing technology. Using clean energy to power low-energy electronic devices has become an important research direction. [0...
