Quick tightening device and tightening method for hard-shell water tank used in space station

Abstract

The invention relates to a fast elastic device and an elastic method for a hard-shell water tank used in a space station, belonging to the field of fast elastic structures, and solves the cumbersome dismantling and fastening operations of the hard-shell water tank in the prior art, low efficiency, and easy failure of the fastening method The problem. The body of the quick release device of the present invention is provided with a groove, and the lug of the water tank is placed in the groove and compressed by the compression end cover. The compression end cover is rotated and installed, and the rotation of the rotating end is limited by the spring force to keep it compressed. state, when the water tank needs to be opened, it is only necessary to overcome the elastic force of the spring to realize the quick opening / closing of the compression end cover, and further realize the quick tightening of the water tank. In the present invention, a tightening screw is arranged at the pressing end of the pressing end cover to be threadedly connected with the body of the quick release device, and the fastening force for keeping the water tank in the launching state closed is provided by tightening the tightening screw. The invention realizes the reliable fastening of the water tank in the launching state and the fast fastening and loosening of the water tank in the 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....
