Abstract

The invention provides a Mars probe solar panel dust removal system which comprises a Mars probe body, a solar panel, a connecting device, a dust removal device, a detection device and a dust removal control device, the dust removal device is installed on the solar panel, and the dust removal control device is installed in the Mars probe body. The dust removal control device is used for controlling the dust removal device to dedust the solar panel, and the solar panel is connected with the Mars probe body through the connecting device. According to the Mars probe solar panel dust removal system, dust on the Mars probe solar panel can be removed in time, it is ensured that the conversion efficiency of the solar panel is in a high-efficiency state, and the service life of a Mars probe is prolonged.

Description

technical field [0001] This application relates to the technical field of Mars rover solar panel dust removal, in particular to a Mars rover solar panel dust removal system. Background technique [0002] The Mars rover uses solar cell wings, or solar panels, to provide electricity. Severe Martian storms often appear on Mars, and under the action of the Martian wind, the entire Mars is filled with Martian dust. Martian dust can accumulate on solar panels through van der Waals and electrostatic forces, degrading battery performance. The Mars Pathfinder test results show that the dust accumulated and adhered to the solar panels reduces the conversion efficiency of the solar panels by about 0.28% per Martian day. After 2 years, it is estimated that the electrical performance of solar panels will decrease by 22% to 89%. In order to ensure the working life of the Mars rover, the Martian dust accumulated on the surface of the solar panels must be removed. [0003] At present, t...
