A new space station external inspection and maintenance device

Abstract

The invention discloses a novel space station extravehicular inspection maintenance unit (EIMU), and belongs to the design field of aerospace crafts. The novel space station EIMU comprises intravehicular monitoring equipment, an antenna and an EIMU device, wherein the intravehicular monitoring equipment and the EIMU device are in communication through the antenna. The intravehicular monitoring equipment comprises a video display terminal, an inspection device control platform and a manual remote control device. The EIMU device comprises solar cell panels, a micro-mechanical arm, sun sensors, nitrogen propellers, a binocular stereo vision camera, a three-axis magnetorquer, a momentum wheel, a satellite-borne computer board and a communication board. The novel space station EIMU can provide extravehicular inspection and maintenance service for large spacecrafts such as space stations and ensure that the spacecrafts can achieve in-orbit operation safely and fulfill tasks smoothly.

Description

technical field [0001] The invention relates to a novel space station external inspection and maintenance unit (EIMU), which belongs to the field of aerospace vehicle design. Background technique [0002] During the operation of the space station in orbit, it is affected by the space environment, or due to the failure of its own equipment, operational errors or human behavior, it will cause many accidents and failures of the space station, such as fire, decompression, loss of control, rollover, and communication interruption. , water pollution, mechanical damage, abnormality of astronauts, electric shock, explosion, etc. The long-term stable operation of the space station in orbit is inseparable from the on-orbit maintenance of astronauts. Astronauts need to carry out preventive and restorative maintenance on the space station on a regular and irregular basis. Extravehicular maintenance has very high requirements for maintenance equipment and astronauts. Extravehicular main...
