A cable power-taking connection mechanism for on-orbit satellite maintenance

Abstract

The invention discloses a cable power-drawing connection mechanism for in-orbit satellite maintenance. The mechanism comprises a housing, a main piston, a driving unit, an end cover, a power-drawing unit, a power-drawing piston, a power-drawing piston limiting reed and a main piston limiting reed. The main piston is arranged in a chute inside the housing and has two ends respectively connected with the driving unit and the main piston limiting reed, and the other end of the main piston limiting reed rests on the inner wall of the housing; the upper surface of the main piston is provided with a commutation mechanism; the driving unit is respectively connected with the main piston and the end cover; the power-drawing unit is fixedly installed on the power-drawing piston; the power-drawing piston is arranged in a chute dug in the upper surface e of the housing, one end of the power-drawing piston is provided with the power-drawing piston limiting reed, the other end of the power-drawing piston limiting reed rests on the inner wall of the housing, and the power-drawing piston is limited in the height direction of the housing through pretension; and the commutation mechanism converts transversal motion along the long-side direction of the housing into vertical motion along the height direction of the housing.

Description

technical field [0001] The invention relates to a cable power-taking connection mechanism for on-orbit satellite maintenance. Background technique [0002] Satellite ground primary power supply detection technology has existed since the invention of satellites. After a century of development, this technology has become a mature high-precision detection technology. Related external equipment such as current clamps and multimeters are very mature and reliable. It can fully meet the needs of satellite ground detection. [0003] Even with adequate testing, power failures still occur frequently in the space. Over the past 30 years, more than 4,000 spacecraft have been launched around the world, and 156 on-orbit failures occurred on 129 different spacecraft. Among them, the faults caused by electric circuits account for about 45%, which is far greater than the on-orbit faults of satellites caused by mechanical structures. The failure of the power supply and distribution system ...

AI Technical Summary

Problems solved by technology

[0005] The power detection of on-orbit satellites is mainly carried out through multiple sets of preset current and voltage sensors distributed on the satellite, but this depends on the polling and collection of the satellite star service bus, and cannot be directly powered on.

[0006] Due to the limitation of space location, the current mechanism for satellites in orbit to obtain power through external equipment is still blank
