Mesh surface hooking-prevention isolating apparatus for satellite-borne annular mesh-shaped antenna

Abstract

The invention relates to a hooking-prevention isolating apparatus for a satellite-borne annular mesh-shaped antenna. The hooking-prevention isolating apparatus comprises peripheral mesh surface baffle films, an upper mesh surface baffle film and a lower mesh surface baffle film; one end of the peripheral mesh surface baffle film structure is a wide edge and the other end of the peripheral mesh surface baffle film structure is a narrow edge; the peripheral mesh surface baffle films are mounted on each of vertical rods of an annular truss; the number of the peripheral mesh surface baffle films is the same as the number of the vertical rods in the annular truss; when the antenna is folded, the narrow edges of the peripheral mesh surface baffle films on the adjacent vertical rods in the annular truss are overlapped, and the wide edges of the peripheral mesh surface baffle films on the spaced vertical rods are overlapped so as to form a closed cylindrical plane circumferentially in the internal of the annular truss; the upper mesh surface baffle film and the lower mesh surface baffle film are arranged on the top end plane and the bottom end plane of the annular truss respectively, and the upper mesh surface baffle film and the lower mesh surface baffle film are connected with the hinges of the annular truss respectively for closing the top end plane and the bottom end plane of the annular truss, and isolating the cable net system of the mesh-shaped antenna and other parts.

Description

technical field [0001] The invention relates to an anti-hook isolation device for a mesh surface of a space-borne mesh antenna, which belongs to the field of space expandable structures. Background technique [0002] The ring mesh deployable antenna is mainly composed of ring truss 5, front tension cable net 1, metal mesh 2, tension array 3 and rear tension cable net 4, etc., as figure 1 shown. Front tension cable net 1, metal net 2, tension array 3 and rear tension cable net 4 belong to the cable net system. The cable net system is an important part of the loop antenna. When the satellite is launched, it is in the retracted state. After the satellite enters orbit, it is deployed to the working state under the action of the ring truss 5, and the cable net system forms a certain profile. The flexible cable net system is very prone to entanglement and hooking during the process from being folded to an unfolded state. To study the management function of the mesh antenna mesh...

Using this network management method alone, it is impossible to manage the network during the entire deployment process

Domestic patent 201310173654.X proposed an automatic rope-retracting mesh management idea, and developed a mesh surface management buckle device. The tension array is managed by the automatic rope-retracting device. This method is simple, but the pulling force of the automatic rope-retracting device It is a process of gradually increasing during the deployment process, which has a great influence on the deployment power of the mesh antenna
