Passive-trigger-type space debris capturing device

Abstract

The invention discloses a passive-trigger-type space debris capturing device. The passive-trigger-type space debris capturing device comprises two capturing storage bins, a trigger system and a base, wherein the trigger system and the base are connected between the two capturing storage bins, and the trigger system and the base are connected. The capturing storage bins comprise storage bin bodies and storage bin connecting rod assemblies connected with the storage bin bodies; and storage bin openings are formed in the storage bin bodies, the storage bin connecting rod assemblies are connected with the base, and the trigger system comprises a motor, a lead screw driving system, a sliding-block-type opening and closing system and a spring trigger. The passive-trigger-type space debris capturing device has the beneficial effects that the space debris capturing device belongs to a passive cleaning method, space debris can be effectively acquired through an integral enveloped-type structure of the two capturing storage bins, and the debris is acquired passively by arranging the trigger system; and because the debris is cleaned mainly depending on natural factors of the outside world, the consumed energy is extremely little, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a passive trigger type space debris capture device. Background technique [0002] The existence of space debris is a serious threat to the safety of spacecraft in orbit. The collision between them and the spacecraft will cause damage to surface devices, lead to failure of spacecraft systems, and bring great harm to the normal operation of spacecraft. At the same time, the continuous expansion of the number of space debris also poses a serious threat to limited orbital resources. At present, the orbits with relatively concentrated debris are sun-synchronous orbits and geosynchronous orbits. When the density of space debris reaches a critical value, the chains between debris Collisions can cause permanent damage to orbital resources. [0003] For space debris larger than 10cm, the kinetic energy is very large, and it will cause devastating damage when it hits a spacecraft. Debris...
