Embodiment Construction

[0018] The present invention is described in further detail below in conjunction with accompanying drawing:

[0019] see Figure 1-3 , the light mechanical collision type space debris capture net claw of the present invention includes a bottom plate, a plurality of claw teeth 1 and claw switch modules installed on the bottom plate. Net pawl pawl tooth 1 is made of the pawl tooth that has spoke respectively on both sides of four. When the net claw claw teeth 1 were closed, the four net claw claw teeth 1 and the spokes on both sides could form a semi-closed capture envelope to prevent the capture target from escaping.

[0020] A rotating ratchet is installed at the root of the claw, and there is a torsion spring inside the ratchet, and the movement of the entire claw is completed by the torsion spring; the ratchet switch / limit is the ratchet limit plate at the root of the claw, and its function is mainly to limit the claw closed angle.

[0021] The pawl switch module includes...

Abstract

The invention discloses a light mechanical collision type space debris capturing web claw. The light mechanical collision type space debris capturing web claw comprises a bottom plate and a pluralityof web claw teeth, wherein the plurality of web claw teeth are mounted on the bottom plate; toothed claw switch module for driving the web claw teeth to be closed when the web claw teeth have collisions with a space debris is also mounted on the bottom plate; the web claw teeth consist of claw teeth with spokes on the two sides; and when the web claw teeth are closed, the plurality of web claw teeth and the spokes on the two sides of the plurality of web claw teeth form a semi-closed capturing envelope to prevent a capturing target from escaping. According to the light mechanical collision type space debris capturing web claw, at the moment of approaching the space debris in the capturing process, the capturing envelope is formed by triggering the switch through triggering a collision triggering switch of the bottom plate and releasing a torsion spring to drive the closed claw teeth; and therefore, the motion of a non-cooperative target is restricted and limited to finally realize thecapturing.

Description

technical field [0001] The invention belongs to the field of capturing non-cooperative targets in space, and relates to a light mechanical collision type space debris capturing net claw. Background technique [0002] In recent years, with the increasing number of space activities, the number of space debris has increased exponentially. Due to external disturbances, most space debris floats and spins in space. Due to the uncertain geometric shape and uncertain motion state of space debris, it is difficult to determine the capture point during the capture process; in addition, the existing space debris capture mechanisms are all driven by motors, which have a large mass and high launch costs. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention proposes a lightweight, low-cost, collision-triggered net claw for capturing space debris with a light mechanical collision type. [0004] In order to achie...
