Pressing and releasing device of folding type solar wing

Abstract

The invention relates to a pressing and releasing device of a folding solar wing, one end of the pressing and releasing device is fixed on a satellite body, the other end of the pressing and releasing device is connected with a solar wing base plate, the pressing and releasing device comprises a pressing rod and a connecting structure, one end of the pressing rod is provided with a limiting part, the other end of the pressing rod is connected with the connecting structure, and the pressing rod penetrates through the solar wing base plate; the solar wing base plate is contracted between the limiting part and the connecting structure, the connecting structure is used for fixing the pressing rod, and the connecting structure can release the pressing rod so that the pressing rod can be separated from the connecting structure. According to the device, the solar wing base plates are pressed and fixed after being folded in the mode that the pressing rods penetrate through folding solar wing base plate blocks, the multiple folding solar wing base plates can be synchronously pressed, the pressing effect of the folding solar wing base plates is guaranteed, when the multiple pressing devices are arranged on the solar wing base plates, all the pressing devices can be synchronously released, and effects of synchronously tightening a plurality of folding type solar wing base plates and synchronously releasing a plurality of pressing points are achieved.

Description

technical field [0001] The invention belongs to the technical field of aerospace satellites, and relates to a pressing and releasing device for a solar wing. Background technique [0002] The solar wing is a device that collects solar energy for energy supply to space satellites. The solar wing is a primary energy array composed of a drive locking mechanism and solar panels. It can convert solar energy into electrical energy in space orbit to ensure the energy of the spacecraft during its orbital operation. Supply is the energy source for space satellites. Space satellites are limited by the carrying space when they are in the launch state. During the launch phase, the solar wings need to be folded and gathered on the side walls of the satellite. When the satellite is separated from the rocket, the satellite solar wings unfold into a flat shape; The continuous energy subsidy of the spacecraft, whether it can be launched smoothly after entering orbit is the primary indicator...

Problems solved by technology

[0003] In the prior art, the compression and release of the solar wing is mostly realized by means of pyrotechnics, and the compression and release of pyrotechnics has a large impact, high cost, high risk, and can only be used once ; In addition, the form of non-firework used for the compression and release of the solar wing is different for the compression and release form of the single-plate solar wing and the multi-plate solar wing. When releasing, the base plate of each solar wing needs to be released synchronously, and there is more than one corresponding pressing and releasing device. However, how to make multiple pressing points release multiple solar wing base plates synchronously is a problem that has not yet been solved in the prior art. The problem to be solved is also the problem to be solved by the present invention. Therefore, the inventor aims at the synchronous release of multi-plate solar wings in China's current aerospace technology field as the core theme to create research to solve the deficiencies in the prior art
