Abstract

The invention discloses a device for unfolding a surface of a space rope system, and is mainly used for solving the problems that the prior art is difficult to mold and has bad stability. The device comprises a plurality of reflectors or transmission surfaces (1), a plurality of flexible pulling cables (2), a satellite platform (4) and a plurality of control mechanisms (3) of the pulling cables, wherein each reflector or transmission surface (1) is composed of a folding ring (4) and a ring connecting joint (5), and is stacked according to the caliber size; one end of each flexible pulling cable (2) penetrates through a corresponding hole of the folding ring (4) of the reflector or transmission surface with the biggest caliber to be tied fixedly, and then penetrates through the folding ring (4) of the other reflector or transmission surface to be tied fixedly; the other end of each flexible pulling cable (2) is connected with the control mechanisms (3) on the satellite platform; and the reflectors or transmission surfaces are connected hierarchically to form a stacked structure composed of the satellite platform and all reflectors or transmission surfaces so as to form a space rope system. The device can achieve effective molding structure, autonomous orbit and pose stability of the whole system, so that the device can be applied in a large antenna or telescope in space.
