Solar panel and satellite

Abstract

The invention discloses a solar panel and a satellite. The solar panel comprises a motor, a driving assembly, a supporting column and a solar assembly. The motor is connected with the supporting column through the driving assembly. The supporting column comprises at least two sleeves which are in threaded connection; the two ends of the supporting column comprise supports. The motor controls the sleeve of the supporting column to rotate through the driving assembly so that the supporting column can be stretched or shortened. The solar module comprises at least two single plates, and the single plates are flexibly connected. The solar module is connected with a support of the supporting column; when the supporting columns extend, the supports drive the single plates to be unfolded. When the supporting column is shortened, the support drives the single plates to be folded. According to the solar panel, complete control over unfolding and folding of the solar assembly is achieved, and the technical problem that in the prior art, the solar assembly cannot be folded again in the space is solved.

Description

technical field [0001] The invention relates to the technical field of satellites, in particular to a solar panel and a satellite. Background technique [0002] Solar panels are indispensable and important equipment on artificial satellites. Due to the large area of ​​the solar panel, when the satellite is carried on the stage of the launch vehicle, the solar panel must be in a folded state so that the satellite can be placed in the limited carrying space of the launch vehicle. When the satellite leaves the launch vehicle and enters the established orbit to start operating, the solar panels need to be deployed to absorb solar energy. [0003] In the prior art, the solar panel is folded and unfolded through a spring structure. When the satellite is on the ground, the solar panel can be folded by artificially squeezing the spring structure. In space, the controllable spring structure elastically expands to deploy the solar panels. However, the defect in the prior art is th...

AI Technical Summary

Problems solved by technology

However, the defect in the existing technology is that the spring structure cannot be recompressed by operation in space, that is, the solar panel cannot be folded and folded again after being unfolded in space.
