Abstract

The invention relates to a vibration power generation device with a permanent magnet and a cable detection system. The vibration power generation device of the permanent magnet comprises a shell, a rotor module, a stator winding and a static permanent magnet. A containing cavity is formed in the shell, the rotor module is arranged in the containing cavity, the rotor module comprises rotor permanent magnets and ferromagnetic cylinders, and the rotor permanent magnets and the ferromagnetic cylinders are sequentially connected in a staggered mode; the address winding is arranged on the shell andis wound on the rotor module; the static permanent magnet is arranged in the accommodating cavity and is spaced from the rotor permanent magnet. According to the vibration power generation device withthe permanent magnets, the rotor permanent magnets and the ferromagnetic cylinders are sequentially connected in a staggered mode, induced electromotive force generated in the rotor winding is more stable, and therefore the efficiency of converting vibration energy into electric energy through the vibration power generation device with the permanent magnets is high.

Description

technical field [0001] The present application relates to the technical field of energy conversion, in particular to a permanent magnet vibration power generation device and a cable detection system. Background technique [0002] As the cornerstone of modern society, energy plays a vital role in the development of human society. With the increasing scarcity of energy in the world, energy conservation and energy recycling have attracted more and more attention from various countries. Renewable energy such as solar energy, wind energy, ocean energy and vibration energy have gradually become the focus of social attention. Vibration is everywhere, inexhaustible and inexhaustible. For example: for distribution network power cable lines, due to the heavy load that the cables bear, low-frequency vibrations can be generated under the action of power frequency magnetic fields and electric fields. [0003] In traditional technology, by installing a permanent magnet vibration motor o...
