Quick loosening-fastening device for hard-shell water tank for space station and loosening-fastening method

Abstract

The invention relates to a quick loosening-fastening device for a hard-shell water tank for a space station and a loosening-fastening method, belongs to the field of quick loosening-fastening structures, and solves the problems that the hard-shell water tank in the prior art is complex in dismounting and fastening operation, is low in efficiency, and has an easily-disabled fastening way. A groove is formed in a quick loosening-fastening device body; a water tank supporting lug is arranged in the groove and is pressed by a pressing end cover; the pressing end cover is rotatably mounted, and the rotation of the rotating end of the pressing end cover is limited by spring elastic force, so that the pressing end cover is kept in a pressed state; when the water tank needs to open, only spring elastic force needs to overcome, so that quick opening/closing of the pressing end cover is realized, and quick loosening and fastening of the water tank is further realized. The pressing end of the pressing end cover is equipped with a tightening bolt which is connected to the quick loosening-fastening device through threads, so that the tightening bolt is tightened to provide fastening force for keeping the water tank under a launching sate to close. The quick loosening-fastening device realizes reliable fastening for the water tank under the launching sate, and realizes quick fastening and loosening for the water tank under a weightless state of the space station.

Description

technical field [0001] The invention relates to the field of quick-tightening structure of a box body, in particular to a quick-tightening device and a fastening method for a hard-shell water tank used in a space station. Background technique [0002] According to the development needs of my country's manned aerospace, it is necessary to study the space water regeneration technology and water purification technology in the medium-to-long-term and long-term manned space missions, so as to realize the regeneration and utilization of water resources, reduce the amount of ground replenishment, and support the long-term stay of personnel in orbit. Life support conditions continue to lay the foundation for my country's space station, manned moon landing and subsequent asteroid exploration projects. [0003] As a functional component for storing liquids such as urine and water, hard-shell water tanks are widely used in space water regeneration systems and water purification systems....
