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-weight mechanical collision type space debris capture net claw, which includes a base plate and a plurality of net claw claw teeth installed on the bottom plate, and the bottom plate is also equipped with driving net claw claw teeth when colliding with space debris Closed claw switch module; the claw teeth of the net claw are composed of claw teeth with spokes on both sides. When the claw teeth of the net claw are closed, several claw teeth of the net claw and the spokes on both sides form a semi-closed catch bag network to prevent the capture target from escaping. During the capture process of the present invention, at the moment of approaching the space debris, the torsion spring is released to drive the closed claw teeth through the collision trigger switch with the trigger bottom plate, thereby forming a capture outer envelope, restricting the movement of non-cooperative targets, and finally realizing arrest.

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 light-weight, low-cost, collision-triggered net claw that is a lightweight mechanical collision-type space debris capture net claw. [0004] In o...
