Expandable space station waste placement cabin based on truss expanding structure

Abstract

The invention discloses an expandable space station waste placement cabin based on a truss expanding structure. The expandable space station waste placement cabin is composed of a supporting cylinder, a supporting sleeve, an upper sliding block, a lower sliding block, an upper end piece, a lower end piece, a short rod, a framework and a skin. The supporting cylinder is connected with the supporting sleeve in a sleeved mode. The upper end piece is installed at an end opening of the supporting cylinder, and the lower end piece is installed at an end opening of the supporting sleeve. The upper sliding block is connected to the supporting cylinder in a sleeved mode, and the lower sliding block is connected to the supporting sleeve in a sleeved mode. One end of the short rod is hinged to the upper sliding block, and the other end of the short rod is hinged to an interface at the one third position of the framework. One end of the framework is hinged to the upper end piece, the other end of the framework is connected with the opposite end opening of the framework in a meshed mode, and the skin covers the whole framework structure. According to the expandable space station waste placement cabin based on the truss expanding structure, the aluminum alloy framework structure and a forming and solidifying skin are adopted, and the strength mass ratio is higher; the expandable structure is adopted, in the transmitting process, the expandable space station waste placement cabin is in the contracting state with small size, the space for occupying a vehicle is reduced, and the carrying efficiency is improved; the expandable space station waste placement cabin is used for the placement of household garbage and abandoned instruments, and the effective utilization space of a space station is increased.

Description

technical field [0001] The invention provides an expandable space station waste placement cabin based on a truss unfolded structure. It is in a contracted state when launching, thereby reducing the space occupied by the carrier. After docking with the space station and unfolding, it houses the space junk generated by the space station, which belongs to the field of aerospace technology. Background technique [0002] my country's "Tiangong" space station, which will be built around 2020, will become an important base for China's space science and new technology research and experiments. The space station consists of a core module and two experimental modules. During the operation of the space station, at most, there will be a cargo spacecraft and two manned spacecraft docking with it. The core module and two experimental modules are launched by the large carrier rocket Long March 5B; the cargo spacecraft and manned spacecraft are launched by the medium carrier rocket Long Ma...

AI Technical Summary

Problems solved by technology

Throwing waste directly out of the cabin will threaten the safety of the space station, and it is carried by a cargo spacecraft, which has insufficient carrying capacity and is difficult to meet the requirements
