Net bag and method for folding and packaging space rope net

Abstract

A method for folding and packaging a space rope net with a pack sealing structure is used for folding and packaging the space rope net. The method comprises the following steps that firstly, an innerring rope is fixed through a tool and then is straightened, and an outer ring rope and a closing-up rope are subjected to W-type folding to form a rope set through an auxiliary rope; then the rope setis pulled up, the rope net is turned over, and a tying rope sequentially penetrates into a rope storage casing pipe on the inner wall of a net pack; and then the rope net is folded into net pack isolation layers according to the W type, the outer ring rope penetrates into the rope storage casing pipe on the outermost layer at the corresponding position, finally rope rings on the upper edges of the outermost layer and the innermost layer of the net pack are sequentially connected in a zipper mode and alternately penetrate through to achieve net pack sealing, and folding and packaging are finished. On the basis of a manual folding mode, net pieces, radial ropes, the inner ring rope and the outer ring rope are effectively isolated, the orderliness of the rope net pulling-out and unfolding process is ensured, the problems of winding, penetrating, knotting and the like in the working process are solved, and reliability is improved.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to a net bag and a method for folding and packing the space rope net. Background technique [0002] In recent years, with the development of aerospace technology and space technology, more and more attention has been paid to space security, and the use of rope nets to capture space debris and abandoned satellites has become a research hotspot. For the rope net structure in the prior art has the characteristics of large area and mesh size, small quality, and thin mesh ropes, etc., the rope net is prone to problems such as hooking, winding and passing through during the working process, while the traditional The packaging method has no sealing structure after folding and packaging, which may easily cause the rope net to fail to open according to the predetermined working procedure. Therefore, a reliable rope net folding packaging method is urgently needed. [0003] In the patent "...

AI Technical Summary

Problems solved by technology

However, since the net bag is folded and packaged into a hexagonal cylinder, the net bag has no sealing structure, so the rope net is directly exposed to the environment. On the one hand, it is easy to be hooked during the ground assembly and test process, resulting in accidental damage At the same time, it will affect the waiting time of the net bag before the on-orbit operation

Since the net bag is a hexagonal cylinder structure, when the rope net is pulled out and opened, an angle will be formed between the rope net and the wall of the net bag, which will cause uneven friction between the rope net and the wall of the net bag, which will directly affect the tension of the rope. Stability of net pull
