Butt-joint locking interface device capable of actively conducting heat for spacecraft

Abstract

The invention discloses a butt-joint locking interface device capable of actively conducting heat for a spacecraft. The butt-joint locking interface device comprises a driving end and a driven end, wherein the driving end comprises a six-degree-of-freedom floating liquid path disconnector movable end and a cold plate pipeline assembly; the cold plate pipeline assembly comprises a cold plate, a hose, a cold plate joint A and a cold plate joint B; the driven end further comprises a six-degree-of-freedom floating disconnector fixed end; a multifunctional pin comprises a height limiting part, a tightening part and a locking part; the height limiting part is a straight pin with a set length; the tightening part is an inclined plane positioned at the front end of the multifunctional pin; the locking part is positioned at the rear end of the height limiting part on the multifunctional pin and is higher than the height limiting part; a guide hole is machined in a shell, one side face of the guide hole is composed of a slope part and a plane part, and a square hole is formed in the bottom of the guide hole. Guiding, positioning and butt joint, active tightening, automatic plugging and unplugging of a six-degree-of-freedom floating liquid circuit breaker and active heat conduction of an exposed load and an exposed platform outside an aircraft cabin can be achieved.

Description

technical field [0001] The invention relates to the field of space application equipment, in particular to a docking and locking interface device for a space vehicle that can actively conduct heat. Background technique [0002] Space vehicles such as space stations and manned spacecraft have arranged a large number of exposure load test platforms on the outer wall of the cabin to expand the exposure test capabilities of space vehicles. At present, the International Space Station has used various forms of payload docking and locking interface devices to support exposure experiment tasks. [0003] However, for the exposed load outside the cabin and the exposed platform outside the cabin, the docking and locking interface device in the prior art cannot automatically capture the exposed load outside the cabin, the degree of automation is not high, the operation ability of the astronaut or the mechanical arm is high, and the mechanism is complicated. Poor maintainability, low re...
