Space debris rotation-eliminating capture device

Abstract

The invention discloses a space debris rotation-eliminating capture device. The device includes a telescopic mechanism, a capture mechanism, a driving mechanism and a control mechanism; one end of thetelescopic mechanism is connected to an on-orbit service spacecraft, and the other end of the telescopic mechanism is connected to the capture mechanism; the capture mechanism is used for capturing space debris by moving to a to-be-captured space debris place under the driving of the telescopic mechanism; the capture mechanism is provided with a rotation-eliminating member and used for eliminating or weakening the rotation of the space debris; and the driving mechanism is used for driving the telescopic mechanism and the capture mechanism to move under the instruction of the control mechanism. Through the arrangement of the rotation-eliminating member on the capture mechanism, buffering effects can be achieved, the rotation of the space debris can be eliminated or weakened, the rotation-eliminating on the space debris in high speed rotation can be realized, and collision is not easy to occur, so that new space debris generated due to collision fragmentation can be avoided, and the structural integrity of the space debris and the on-orbit service spacecraft can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of spacecraft on-orbit service, in particular to a space debris derotation capture device. Background technique [0002] As human space activities become more and more frequent, space debris is constantly produced and has become the main source of space pollution. In order to ensure the safety of spaceflight and avoid the occupation of important orbits (for example, geosynchronous orbits), it is necessary to clean up space debris. [0003] When the prior art cleans up the space debris, it utilizes the in-orbit service spacecraft connected with the mechanical arm to catch the space debris. After the in-orbit space server approaches the space debris, the robotic arm stretches out to capture the space debris. [0004] The inventors have found that the prior art has at least the following problems: for space debris (especially invalid spacecraft) with complex appearance and high-speed rotation, it is difficult...

Problems solved by technology

[0004] The inventors have found that the prior art has at least the following problems: for space debris (especially invalid spacecraft) with complex appearance and high-speed rotation, it is difficult to operate only by the mechanical arm, and it is prone to collisions and collisions. Not only is it easy to cause damage to the capture mechanism, but it may also generate new space debris
