A Magnetically Coupled Blunt Body Disturbance-induced Vibration Generator

Abstract

The invention relates to a magnetically coupled blunt body disturbance-induced vibration generator, which belongs to the technical field of new energy sources. The main body is provided with a body cavity and two horizontal plates with external ear plates, and the two ends of the baffle are mounted on the horizontal plates; the guide holes at both ends of the blunt body are set on the two outer pins, and each outer pin is also covered with two outer springs, and the two outer pins The end is installed on the outer ear plate, and the two ends of the outer spring are against the blunt body and the outer ear plate; the outer magnet is installed on the cross arm of the blunt body, and the outer magnet passes through the long slot of the baffle and is opposite to the vertical plate of the main body; The end caps with inner ear plates at both ends are installed at the end of the body cavity, and the two ends of the inner pin covered with the slider and two inner springs are installed on the inner ear plate, and the two ends of the inner spring are against the slider and the inner ear plate; on the slider The inner magnet and the outer magnet are attracted and installed facing each other; there are cams on both sides of the slider, and the cam surface is composed of the bottom surface, the top surface and the slope connecting the top surface and the bottom surface; When the piezoelectric vibrator is formed, the free end of the substrate leans against the center of the inclined surface of the cam surface when it is not working.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a magnetically coupled blunt body disturbing flow-induced vibration generator, which is used to construct a self-powered river monitoring system. Background technique [0002] There are thousands of rivers all over the territory of our country. In recent years, due to inadequate treatment of industrial wastewater, soil erosion, and improper use of pesticides and fertilizers, some rivers have been polluted to a certain extent, unable to meet the needs of residents and farmland irrigation. In addition, due to the imperfect flood control facilities and lack of relevant flood control facilities for small and medium-sized rivers in some areas, there are dangers of embankment collapse or flooding when the flood season approaches, which directly threatens the lives and property safety of people along the coast. Therefore, river monitoring has been highly valued by releva...

Problems solved by technology

In recent years, due to insufficient treatment of industrial wastewater, soil erosion, and improper use of pesticides and fertilizers, some rivers have been polluted to a certain extent, unable to meet the needs of residents' lives and farmland irrigation.

In addition, due to the imperfect flood control facilities and lack of relevant flood control facilities for small and medium-sized rivers in some areas, there are dangers of embankment collapse or flooding when the flood season approaches, which directly threatens the lives and property safety of people along the coast.

Therefore, river monitoring has been highly valued by relevant state departments; at the same time, domestic experts and scholars have also proposed corresponding monitoring methods and means, including water quality monitoring technology for river water pollution, rainfall, water level and other natural disasters for flood control and mudslides. There are many monitoring technologies such as river water flow rate, as well as various micro energy harvesters that supply power to the monitoring system. However, the existing micro energy harvesters have certain problems in terms of reliability and flow rate adaptability, which seriously hampered its promotion
