A turbine piezoelectric generator

Abstract

The invention relates to a turbine-type piezoelectric generator, which belongs to the technical field of new energy sources. There are body cavities on the upper and lower sides of the shaft cavity of the main body, and end covers are installed on the side walls of the shaft cavity and the body cavity; one end of the main shaft placed in the shaft cavity protrudes from the bottom wall of the shaft cavity and is equipped with a turntable with blades and a main magnet The upper and lower ends of the longitudinal beam of the bracket are provided with beams with inclined mounting surfaces; the left and right sides of the cam body of the exciter are respectively provided with left and right pins, and a set of cams are respectively provided on the upper and lower sides. The cam surface is composed of a bottom surface, an inclined surface and a top surface The cam body is placed in the body cavity, and the right pin with the auxiliary magnet at the end protrudes through the bottom wall of the body cavity, and the main and auxiliary magnets form a magnetic pair; the cam body presses the buffer spring on the bottom wall of the body cavity, and the frequency modulation block is installed The guide hole of the longitudinal beam is set on the left pin, and the end of the left pin is equipped with a stopper; the left and right springs are respectively crimped between the longitudinal beam, the stopper and the cam body; the piezoelectric vibrator with a free end and a top block is installed on the mounting surface of the bracket , the piezoelectric vibrator is formed by bonding the substrate and the piezoelectric sheet, and the top block leans against the cam surface.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a turbine piezoelectric generator, which is used to construct a self-powered river monitoring system. Background technique [0002] There are thousands of rivers scattered throughout my country, and river monitoring has been highly valued by relevant state departments; at the same time, domestic experts and scholars have also successively proposed corresponding monitoring methods and means, including water quality monitoring technology for river water pollution, and flood control Rainfall, water level, and river water flow rate monitoring technologies for natural disasters such as mudslides, as well as various micro-miniature generators for power supply for river monitoring systems, but the existing micro-miniature generators are in reliability and flow rate adaptability, etc. There are certain problems in all aspects, which seriously hinder its popularization and ap...
