Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the present invention is a tension-adjustable and instant-release rope net storage and release mechanism, which is composed of an outer cylinder 2, a rope 3, a tension adjuster 4, a rope cutter 6 and the like. The outer cylinder 2 provides support for the whole mechanism and provides storage space for the net bag 1 . Two ropes 3 are tied up on the upper and lower sides of the net bag respectively to fix the net bag. The two ends of the rope 3 are connected to the two ends of the tension adjuster 4 . Rope 3 passes through two rope cutters 6 up and down respectively. The rope cutter 6 is fixed on the outer cylinder 2 by the rope cutter bracket 5 .

[0030] Such as figure 2 As shown, the tension adjuster 4 is made up of a rope connecting ring 8, an adjusting bolt 9, an adjusting nut 10, and an adjuster spring 11. The adju...

Abstract

The invention belongs to the field of space debris cleaning, and particularly relates to a tension-adjustable instantly-released rope net storage and release mechanism. The mechanism comprises a net bag, an outer cylinder, a rope, a tension adjuster, a rope cutter support and a rope cutter. The outer cylinder supports the whole mechanism and provides a storage space for the net bag; the two ends of the rope are connected with the two ends of the tension adjuster to form a closed circular ring bundling net bag, and the tension adjuster is used for adjusting tension on the rope; the rope cutter is arranged on the rope cutter support and comprises a blade, and the blade is driven to cut off a rope and release the net bag according to a trigger signal. Aiming at the problems that the rope creeps after vibration and the tension is reduced, the tension adjuster can adjust the tension of the rope after the rope creeps, so that the tension of the rope is kept at an expected value; in addition, the rope cutter can cut off the rope immediately when the rope net needs to be launched, the fixed rope net is loosened, and execution of subsequent control instructions is facilitated.

Description

technical field [0001] The invention belongs to the field of space debris cleaning, and in particular relates to a rope net storage and release mechanism with adjustable tension and instant release. Background technique [0002] At present, in addition to the spacecraft that are still in normal use, there are still invalid man-made objects left in outer space, that is, space debris. At present, the number of space debris has reached tens of thousands, and these space debris always threaten the safety of working satellites, so it is urgent to clean up space debris. In the field of space debris removal, flexible capture deorbiting is an emerging deorbiting technology. This technology wraps the target with a structure such as net or cloth and forms a combination of reliable connections with the space tug through ropes, and then the space tug tows the target to perform the task of deorbit clearance. Before the rope net is launched, a special container is required to accommodat...
