Problems solved by technology

[0003] The purpose of the present invention is to provide a three-dimensional truss-type in-orbit repairable inflatable solar panel to solve the problem that astronauts need to walk in the space environment when some solar panels or battery substrates are damaged or aging. It takes a long distance to replace the damaged or aging solar panels as a whole, which causes a waste of resources and poses a threat to the safety of astronauts.

Abstract

The invention provides an inflatable and expandable three-dimensional truss on-track maintainable solar panel. In the case of on-track motion of the solar panel, an astronaut needs to walk in space environment to integrally replace the solar panel which needs to be replaced, which causes threat to life safety of the astronaut. An inflatable and expandable three-dimensional truss is composed of a plurality of inflatable and expandable three-dimensional truss units which are in sequential end-to-end communication, and the head and tail ends of the inflatable and expandable three-dimensional truss are fixedly connected with a triangular supporting plate; an adjacent side plane between each inflatable and expandable three-dimensional truss unit and two guide tubes is internally equipped with a solar cell substrate which is connected with a main supporting tube, and the solar cell substrate is composed of a cell thin sheet, a supporting structure board and a plurality of first magnet exciting coils; the cell thin sheet is supported by the supporting structure board, and the supporting structure board is fixedly equipped with the first magnet exciting coils; and the cell thin sheet is attracted with the supporting structure board together by means of a magnetic force, and a capture board is arranged outside the solar cell substrate. The solar panel of the invention is used in a manned spacecraft such as a space station and the like.

Description

technical field [0001] The invention relates to an in-orbit repairable inflatable deployable solar panel, which belongs to the field of aerospace technology. Background technique [0002] Solar panels are an important part of manned spacecraft such as space stations, which convert the collected solar radiation energy into electrical energy to provide electrical support for spacecraft. The space environment is extremely complex, high vacuum, strong ultraviolet rays, atomic oxygen, "cold black" and a large number of micro meteors and space debris, which cause damage or aging of solar cells during orbital operation, which requires replacement and maintenance. The traditional method is for astronauts to replace some of the damaged or aging solar panels as a whole. In some cases, the damage is only a small part, and the overall replacement will cause a waste of resources. In addition, the size of the solar panels is very large after deployment. , Astronauts need to walk a long ...
