[0034] The present embodiment is based on a solar energy-based electrostatic energy collector, including a housing 5, an electret assembly 3, a magnet structure 4, and a cover plate 1 are arranged at the upper end of the housing 5 inside the housing 5, and the inside of the cover plate A collection electrode assembly 2 is provided, and a light concentrating device 61 is provided above the cover plate 5; the housing 5 can prevent the electret assembly 3 from being disturbed by air flow, and the connection between the collection electrode assembly 2 and the electret assembly 3 There is a gap between them, and the two do not touch each other. The electret assembly 3 is composed of pyrolytic graphite sheets, insulating layers, electret layers and protective electrodes stacked from bottom to top, and the pyrolytic graphite sheets, insulating layers, and electret layers are all round Shape, the diameter of the insulating layer is smaller than the diameter of the pyrolytic graphite s...

Embodiment 3

[0038] This embodiment is based on an electrostatic energy collector based on solar energy. The electret assembly is formed by stacking pyrolytic graphite sheets, insulating layers, and electret layers from bottom to top. The diameter of the pyrolytic graphite sheets is 12 mm. The thickness is 25 μm, with Si as the substrate to carry the electret layer, SiO 2 As electret layer material, SiO 2 It has extremely high charge density and long-term stability, and through the oxidation process of Si, SiO can be produced 2 , the processing is simple. Since each layer of material is very thin at the μm level, we use MEMS processing technology to process it layer by layer. Two uniformly distributed electret structures are set on the surface of the electret, the central angle of each electret structure is 90°, and then the electret is charged by the method of corona, correspondingly, in the collecting electrode Four collection electrodes with the same shape are arranged on the module,...

Abstract

The invention discloses an electrostatic type energy collector based on solar energy. The collector comprises a light condensing device, a magnet, an electret assembly, a collection electrode assembly, a housing and a cover plate. The electret assembly consists of a pyrolysis graphite flake, an insulation layer, an electret and a protection electrode. Due to the diamagnetism of the pyrolysis graphite flake, the electrets will be freely suspended to the upper part of the magnet under the effects of the magnetic force resisting ability. By use of double convex lenses, sunlight is condensed to the edge of the pyrolysis graphite flake and the electret rotates. Capacitance is formed between the collection electrode and the electrets, so when the electret assembly rotates, the relative area of the capacitor is changed, and charge on the collection electrode is also changed. Through an energy management circuit, charge on the collection electrode is stored and it is achieved that solar energyis converted into electric energy.

Description

technical field [0001] The invention relates to the technical field of energy collectors, in particular to an electrostatic energy collector based on solar energy, which can convert solar energy into electrical energy to realize energy collection. Background technique [0002] With the rapid development of the economy, people's demand for energy is becoming more and more obvious, but the conventional way of energy supply and extraction has been difficult to meet people's growing demand. Finding new energy technologies has become an effective way to solve this problem. There are various energies in nature, such as solar energy, vibration energy, thermal energy and nuclear energy, etc. These energies can be utilized through energy conversion technology. For example, vibration mechanical energy in the processing environment is converted into electrical energy through the piezoelectric effect, energy is collected through biochemical reactions, heat is converted into electrical ...
