A Mechanical Rope Net Compression and Release Mechanism

Abstract

The invention belongs to the field of space debris cleaning, and in particular relates to a mechanical rope net compression release mechanism. It includes an upper fixed ring, a middle fixed ring, a lower fixed ring, a pressing plate and a torsion spring; there are multiple pressing plates, and a four-bar linkage mechanism is formed through connecting rods between the pressing plate, the middle fixing ring and the lower fixing ring. The upper connection point of the linkage mechanism close to the pressure plate is connected with the upper fixed ring through the upper link; when the upper fixed ring is pressed down, the four-bar linkage pushes the pressure plate to move forward, and multiple pressure plates are spliced ​​into one The circumference compresses the rope net tightly; a torsion spring is provided at the connection between the lower part of the compression plate and the short connecting rod. When the pressure on the upper fixed ring disappears, the compression plate pushes the four-bar linkage to lift up under the action of the torsion spring. The compression plate moves outwards to open the compressed rope net. The invention is a purely mechanical device that uses the action of opening the cabin to open the release mechanism, reducing the process of separately releasing the rope net, thereby improving the reliability of aerospace products.

Description

technical field [0001] The invention belongs to the field of space debris cleaning, and in particular relates to a mechanical rope net compression release mechanism. Background technique [0002] With the continuous development and progress of aerospace technology, there are more and more spaceflight objects, discarded, invalid, and end-of-life objects abound, and more and more garbage is created in space. In order to recycle these garbage and purify space environment, there is an urgent need for a recovery equipment and device. Before the recovery rope net is sent, it needs to be compressed, and the device is opened when it needs to be recovered. Compression and release reliability are required to be very high. [0003] In the past, pyrotechnics and electric power devices were basically used at home and abroad, and the recovery device released the recovery device after a signal was given in space. Similar products both at home and abroad use pyrotechnic explosives to cut...

Problems solved by technology

[0004] In addition, whether it is electric fuse or pyrotechnics, it is greatly affected by the environment. In the sky, the ambient temperature is 150 degrees to minus 100 degrees, and the temperature difference varies greatly. Therefore, it is difficult to guarantee the reliability of electric fuses or pyrotechnics.
