An anti-floating device and equipment for equipment in a microgravity environment

Abstract

The invention relates to an anti-drifting device and equipment for equipment in a microgravity environment. The anti-drifting device includes an anti-drifting component and a guiding and positioning component. The anti-drifting component includes a locking pin and an anti-drifting guide sleeve. Tight through hole, the locking pin can be axially moved and inserted in the locking through hole; the guide positioning assembly includes a guide sleeve and a guide pin, the guide sleeve is provided with a guide through hole, and the guide pin can move axially Inserted in the guide through hole; the height of the guide pin is greater than that of the locking pin. The anti-floating component and the guiding and positioning component of the present invention are used in a complete set to realize the functions of positioning, guiding and anti-floating. The axial direction of the pin shaft is translated. The guide pin guides the equipment to continue to cooperate with the anti-floating component (the height of the guide pin is greater than the height of the locking pin). At this time, the anti-floating guide sleeve on the equipment and the locking pin complete the precise positioning.

Description

technical field [0001] The invention relates to the technical field related to the microgravity environment, in particular to an anti-floating device and equipment in the microgravity environment. Background technique [0002] The anti-floating locking device in the microgravity environment is generally used in the field of manned spaceflight.

[0002] The anti-floating locking device in the microgravity environment is generally used in the field of manned spaceflight. When the equipment needs to be operated, repaired and replaced by astronauts on orbit, especially when the maintenance and replacement of extravehicular equipment is required, the astronauts use tools to tighten the fastening screws (device) of the equipment. ) is released, the device will be affected by the initial acceleration in the microgravity environment, and there is a risk of drifting away, causing the risk of equipment loss in space, mission failure, and formation of space junk, which will affect the safety of spacecraft and astronauts. In order for the personnel to complete the on-orbit maintenance and replacement work more reliably, it is necessary to take corresponding anti-floating and installation and positioning measures for the equipment to be repaired and replaced.

[0003] At present, the anti-drifting devices used in the on-orbit maintenance and replacement of my country's space products have basically not passed the on-orbit verification.
