Anti-drift apparatus of device in microgravity environment and device

Abstract

The invention relates to an anti-drift apparatus of a device in a microgravity environment and the device. The anti-drift apparatus comprises an anti-drift assembly and a guide positioning assembly; the anti-drift assembly comprises a locking pin and an anti-drift guide sleeve; the anti-drift guide sleeve is provided with a locking through hole; the locking pin can be inserted into the locking through hole in an axial movement manner; the guide positioning assembly includes a guide sleeve and a guide pin, a guide through hole is formed in the guide sleeve, and the guide pin can be inserted into the guide through hole in an axial movement mode; and the height of the guide pin is greater than that of the locking pin. According to the invention, the anti-drift assembly and the guide positioning assembly are combined for use, so that the positioning, guide and anti-drift functions are achieved; coarse positioning of the device is implemented through the guide positioning assembly, and at the moment, the device can rotate with the axis of the guide pin as the axis, or can horizontally move in the axial direction of the guide pin. The guide pin guides the device to be further installed with the anti-drift assembly (the height of the guide pin is greater than that of the locking pin), and at the moment, fine positioning is finished by the anti-drift guide sleeve on the device and the locking pin.

[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.
