In-orbit material experiment box mechanism

Abstract

The invention relates to an on-orbit material experiment box mechanism, which comprises an experiment box, an on-orbit mounting bracket, a locking and releasing mechanism and a locking plate, and is characterized in that the on-orbit mounting bracket is fixedly mounted on an outer side platform of an on-orbit spacecraft; the locking plate is fixedly mounted on the on-orbit mounting bracket; an assembly cavity with an opening is formed in the side wall of the experiment box; the locking and releasing mechanism is mounted in the assembly cavity; the locking and releasing mechanism is provided with a locking bulge, the locking bulge is movably installed at the opening of the assembly cavity, the locking plate is provided with a locking groove, and the locking protrusion is matched with the locking groove; and the locking bulge extends out of or retracts into the assembly cavity, so that the locking bulge is clamped to or separated from the locking groove, and locking or releasing of the locking plate and the experiment box is realized. According to the invention, the experiment box can be integrally and repeatedly locked and released on orbit, locking and releasing are achieved through clamping and separating of the locking bulge and the locking groove, the structure is simple, operation is easy, and astronauts can conveniently complete locking and releasing of the experiment boxthrough on-orbit operation.

Description

technical field [0001] The invention relates to a material exposure experiment under the cabin space environment, in particular to an on-orbit material experiment box mechanism. Background technique [0002] In order to meet the needs of future deep space exploration, it is of far-reaching significance to study the in-orbit service behavior of materials in the field of basic disciplines, and to study the in-orbit characteristics and changes of materials. During the missions of the former Soviet space station and the International Space Station, on-orbit exposure tests of metal and non-metal materials have been verified many times, and significant scientific research results have been achieved. However, our country is still in its infancy in terms of space material exposure. In order to meet the task requirements of material space exposure, it is urgent to involve an experiment in which the material to be exposed can be reinstalled, locked and released repeatedly in orbit, an...

However, our country is still in its infancy in terms of space material exposure. In order to meet the task requirements of material space exposure, it is urgent to involve an experiment in which the material to be exposed can be reinstalled, locked and released repeatedly in orbit, and automatically unfolded and closed. box
