Abstract

A high-voltage polarized self-clearing trolley for moon dust on the surface of solar cells belongs to the field of moon dust removal technology, mainly to solve the problems of low safety, small application range, low work efficiency and problems in moon dust removal devices in the prior art. For the problem of high energy consumption, the present invention includes a dust removal layer, a driving layer, an energy supply layer and a circular support plate, and uses a high-voltage module power supply to convert the 12V DC voltage input by the solar panel into an adjustable high-voltage power supply of 0-3000V. Connect the high-voltage output end to the protected plane and the dust removal electrode respectively. When the two are sufficiently close (2-6mm), a strong electric field will be generated between them. Under the action of the electric field, the moon dust particles will be polarized and brought along with the dust removal The opposite charge of the electrode is adsorbed to the dust removal electrode under the action of the electric field force, and the invention is mainly used for removing the moon dust on the lunar solar panel.

Description

technical field [0001] The invention relates to the technical field of moon dust removal, in particular to a self-clearing trolley for moon dust on the surface of a high-voltage polarized solar cell. Background technique [0002] Moon dust is produced by factors such as meteorite impact on the lunar surface, long-term exposure to the radiation environment of high-energy charged particles, and the nearly 300°C temperature difference between day and night that causes lunar rocks to expand with heat, contract with cold, and crack. Therefore, it is inherently fine and uniform. The diameter is about 40 ~ 120μm, easy to charge, strong adhesion and so on. It is easy to accumulate on the surface of sensitive power components such as photoelectric arrays and radiators, reducing their performance. Currently, there are three main methods for removing moon dust: [0003] Electric curtain dust removal, it is to design a layer of parallel and alternating electric curtains on the protecte...
