Device and method for collecting track vibration energy based on giant magnetostrictive rod

Abstract

The invention discloses a device and a method for collecting track vibration energy based on a giant magnetostrictive rod, which solve the problems of low conversion efficiency and difficult installation of the existing track vibration energy collecting technology. The device comprises an upper end cover and a lower end cover, wherein a circular groove for fixing a lower magnetic conducting block is formed in the lower end cover; the giant magnetostrictive rod is placed on the lower magnetic conducting block; a coil framework sleeves the giant magnetostrictive rod; an induction coil winds on the coil framework, and is externally connected with an adjusting circuit through a lead wire; an output end of the adjusting circuit is connected with an energy storage; a permanent magnet sleeves the coil framework; the bottom end of an input ejection rod is in contact with the giant magnetostrictive rod, and the top end is connected with an adjusting nut in a threaded manner; the upper end cover is connected with the lower end cover in a threaded manner; and a disk spring is arranged between a shaft shoulder of the input ejection rod and the upper end cover. The method provided by the invention is characterized in that: the energy storage and the device for collecting track vibration energy based on the giant magnetostrictive rod are installed between sleepers under a track; the adjusting nut is rotated to be in contact with the bottom surface of the track; and the giant magnetostrictive rod collects track vibration energy. The device and the method provided by the invention have the advantages of high energy conversion efficiency and convenient installation.

Description

technical field [0001] The invention relates to a device and method for collecting orbital vibration energy based on giant magnetostrictive rods. Background technique [0002] In recent years, ballastless track has been popularized in a large area. The ground of ballastless track is flat and there is no gravel bedding, which is conducive to the installation and fixing of various related equipment. At the same time, with the development of rail transit, a large number of trackside equipment such as wireless sensors and radio frequency coils are used in the signaling system. Due to the lack of electricity in remote areas, the supply of electricity is troublesome and costly, so most of these trackside equipment are powered by batteries. However, the life of the battery is limited, and the workload and cost of replacing a huge number of batteries on a regular basis are often unbearable; a large number of discarded batteries also bring irreversible pollution to the environment; ...
