Problems solved by technology

[0004] However, the traditional shaking power generation scheme has the following disadvantages. The existing linear system has a narrow response frequency band. At present, most of the existing shaking power generation devices belong to the linear system. Generally speaking, the linear system can only achieve the maximum energy near the resonance frequency of the system. capture, while around other frequency points, the energy conversion efficiency drops sharply
However, the existing common sloshing phenomena generally have a wide frequency band, so systems with a narrow response frequency band generally have low conversion efficiency of sloshing energy.

Description

technical field [0001] The invention relates to the technical field of power generation systems, in particular to a magnetically constrained rocker arm type vibration power generation device and system. Background technique [0002] With the advancement of society and the development of science and technology, the demand for energy in human society is increasing, and traditional fossil energy is difficult to meet human demand for energy. Therefore, the development of new energy has become a current research hotspot. The surrounding environment contains a large amount of clean energy such as solar energy, wind energy, water energy, vibration or shaking mechanical energy, which provides conditions for the development of new energy. [0003] According to the principle of energy conversion, the existing shaking power generation schemes can be roughly divided into three types: electromagnetic, piezoelectric, and electrochemical. The electromagnetic shaking power generation devic...
