Problems solved by technology
Unlike cooperative targets, non-cooperative targets cannot identify capture points and thus cannot be captured using traditional touchpoints
In addition, most space debris has geometric uncertainties due to their own disintegration or damage

Embodiment Construction
[0019] The present invention is described in further detail below in conjunction with accompanying drawing:
[0020] see figure 1 and figure 2 , the present invention is aimed at the arresting device of space debris, includes a rotating claw unit 1, and an actuator, the actuator includes a micro switch 2, a drive unit, a universal joint, a rotary transformer 4, a protective cover 5, a base plate and a pyrotechnic cutter 6. The driving unit of the catch mechanism is used to provide the movement power of the catch mechanism. The executive mechanism of the catch mechanism is used to execute the catch action, and the executive mechanism part is made up of 5 sets of rotating claw units 1, 4 sets of micro switches 2, and is formed by 8 double universal joints between each other. The micro switch 2 is divided into two categories, the thermal cutter 6 constraint position micro switch 2 assembly is used to monitor the release state of the product movement after the pyro cutter 6 is...

The invention discloses a capture device for the outer envelope of space debris with uncertain shape, which includes a bottom plate and several rotating claw units installed on the bottom plate. A buffer mechanism is installed under the rotating claw unit and is used to drive the rotating claw unit. Action actuator; the actuator is a number of execution units, each execution unit includes a micro switch and a universal joint; the front end of the first execution unit is provided with a stepping motor, and the rear end of the last execution unit is provided with a Real-time display of the angle signal of the rotating claw, status monitoring and a resolver for backup control; a pyrotechnic cutter is also installed on the outer bottom of each rotating claw unit. When the present invention collides during the capture process, the buffering of the claw-fan mechanism and the compression spring prolong the impact force action time, thereby reducing the impact force. In addition, the invention also connects the universal joint and the micro switch in series, so that the five claw-fan mechanisms can be controlled in series, which greatly reduces the complexity of the control and improves the reliability of the control.
Description
technical field [0001] The invention belongs to the field of capturing non-cooperative targets in space, and relates to a device for capturing outer envelopes of space debris with uncertain shapes. 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 non-cooperative targets float and spin in space. Unlike cooperative targets, non-cooperative targets cannot identify capture points and thus cannot be captured using traditional touchpoint methods. In addition, most space debris has geometric uncertainty due to its own decomposition or damage. Moreover, under the effects of gravitational perturbation, solar light pressure, and atmospheric resistance, space debris generally has motion modes such as spin. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and ...
