Embodiment Construction
[0019] The present invention is described in further detail below in conjunction with accompanying drawing:
[0020] see figure 1 with 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 i...

The invention discloses an external envelope catching device for space debris with an uncertain shape. The external envelope catching device for the space debris with the uncertain shape comprises a bottom plate and a plurality of rotating claw units, wherein the rotating claw units are mounted on the bottom plate; a buffering mechanism and an executing mechanism, which is used for driving the rotating claw units to act, are mounted under the rotating claw units; the executing mechanism comprises a plurality of executing units; each executing unit comprises a microswitch and a universal joint;a stepping motor is arranged at the front end of the first executing unit; a rotary transformer used for displaying angle signals of rotating claws in real time, monitoring state and controlling backup is arranged at the rear end of the last executing unit; and a fire work cutter is also mounted at the bottom of the external side of each rotating claw unit. When the external envelope catching device for the space debris with the uncertain shape is collided in the catching process, the acting time of impact force is prolonged through the buffering of claw-fan mechanisms and the adoption of a compression spring so that the impact force is reduced. In addition, according to the external envelope catching device for the space debris with the uncertain shape, as the universal joints are connected with the microswitches in series, the five claw-fan mechanisms are controlled in series so that the control complexity is greatly reduced and the control reliability is improved.
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 ...
