Electromagnetic vibration generating device of permanent magnet and application thereof in vibration detection system

Abstract

The invention discloses an electromagnetic vibration generating device of a permanent magnet and application thereof in a vibration detection system, and relates to a device for recycling energy from mechanical vibration to realize energy utilization. The electromagnetic vibration generating device of the permanent magnet is composed of two outer cylinder end covers, a columnar hollow shaft, an inner side coil, a columnar inner cylinder, two fixed annular permanent magnets, a moving annular permanent magnet, a columnar outer cylinder and an outer side coil. According to the invention, the shortcomings that the existing vibration generating device only can collect the vibration energy in the vertical direction and the energy conversion efficiency from the vibration energy to electric energy is relatively low are overcome; the electromagnetic vibration generating device of the permanent magnet is used as a unique power supply of the vibration detection system so that the vibration detection system becomes a self-powered vibration detection system; and the self-powered vibration detection system is combined with a voltage doubling circuit, a wireless transmitting module, a wireless receiving module, a single-chip module and a personal computer, thus the inconvenience of arranging a power supply and a lead outside the traditional vibration detection device is overcome, and a worker can master the vibration conditions without arriving at the site.

Description

Technical field [0001] The technical solution of the present invention relates to a device that recovers energy from mechanical vibration to be used as energy source, specifically an electromagnetic vibration power generation device of permanent magnet and its application in a vibration detection system. Background technique [0002] Nowadays, low-power power supplies are widely used in bridge state detection, environmental monitoring, medical care and automobile manufacturing. The fatal disadvantages of batteries as low-power power sources are high cost, limited lifespan, and improper handling of discarded batteries, which will cause serious pollution to the environment; the disadvantages of solar power and wind power as low-power power sources that replace batteries are that their access is affected by environmental factors And geographical conditions, it is impossible to be widely used; vibration power generation devices have the advantages of long service life, strong practic...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide an electromagnetic vibration power generating device of a permanent magnet and its application in a vibration detection system. Annular permanent magnet Three axially magnetized annular permanent magnets constitute a permanent magnet spring, and coils are respectively arranged inside and outside the moving annular permanent magnet, thereby converting mechanical vibration energy collected in multiple directions into electrical energy, overcoming the existing vibration The power generation device can only collect vibration energy in the vertical direction, the energy conversion efficiency from vibration energy to electric energy is relatively low, the mechanical performance requirements of the device material are high, the structure and its manufacturing process are relatively complicated, the performance stability is poor, and the service life is relatively short. Shortcomings; the permanent magnet electromagnetic vibration power generation device is applied to the vibration detection system, no external power supply and lead wires are required, and remote monitoring is realized, which overcomes the disadvantages of the inconvenience of adding power and lead wires to the traditional vibration detection device, and the staff do not have to go to the The vibration of equipment or devices can be grasped on site
