Abstract

The invention discloses an electrostatic energy collector and an electrostatic energy collecting method. The electrostatic energy collector comprises a vibrating table (101), the vibrating table (101) is fixedly connected with a first end of a first transverse beam (102) and a first end of a second transverse beam (103), the first transverse beam (102) is parallel to the second transverse beam (103), vertical projections of the first transverse beam (102) and the second transverse beam (103) coincide, the first transverse beam (102) and the second transverse beam (103) are conductors, a first mass block (104) is fixed on the first transverse beam (102), one side of the second transverse beam (103), which is close to the first transverse beam (102), is coated with an electret layer (106), one side of the second transverse beam (103), which is far from the first transverse beam (102), is fixedly provided with a second mass block (105), a first guide wire (107) is connected with the first transverse beam (102) and a first end of a load (109), and a second guide wire (108) is connected with the second transverse beam (103) and a second end of the load (109). By means of the electrostatic energy collector and the electrostatic energy collecting method, the energy collecting efficiency can be increased.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to an electrostatic energy collector and an electrostatic energy collection method. Background technique [0002] In the natural environment, there are different energy sources such as solar energy, wind energy, thermal energy, and mechanical energy, which can be converted into electrical energy. Among them, vibration energy has become a hot spot because of its ubiquity and green energy. Currently, vibration energy conversion The main way to generate electrical energy is to collect vibration energy that matches the vibration frequency of the resonator through a linear resonator and convert it into electrical energy. However, linear resonators only have high efficiency in collecting vibration energy near the resonance frequency. Once the vibration frequency of the external environment deviates from the resonance frequency, the energy collection efficiency is low. Contents of the in...
