Abstract

The invention discloses a miniature piezoelectric power generation device, which is mainly composed of a box body, a return spring, an oscillating spring, a mass block, piezoelectric ceramics, an insulating material and a dowel bar. Ceramics, insulating materials are provided on the left, right and lower sides of the piezoelectric ceramics. A mass block is provided in the box above the piezoelectric ceramics. The mass block and the piezoelectric ceramics are connected by an oscillating spring. The upper side of the box above the mass block There is a dowel rod in the middle, and return springs are arranged on both sides of the dowel rod in the box. The device of the invention has simple structure, no mechanical moving parts, is not easily damaged, has small volume, low cost, energy saving and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a micro piezoelectric power generation device. Background technique [0002] At present, the research on piezoelectric power generation has been gradually deepened in the United States, Japan, the Netherlands, Spain and other countries, and a series of scientific research results have been obtained. For example, the Princeton Marine Power Technology Company of the United States has developed a piezoelectric polymer power generation device that uses the pressure and stress of ocean waves and currents; Japanese researchers have developed a power generation floor, which is installed on the sidewalk of Tokyo's bustling Shibuya Railway Station. The floor can generate electricity when passing the floor; in addition, the dance floor power generation floor of Westergas Park in Rotterdam, the Netherlands, the mechanical energy of people dancing is converted into elect...
