The invention discloses a cable segment connecting and cable length adjusting device of an antenna with a deployable cable mesh reflector. The cable segment connecting and cable length adjusting device comprises a support barrel and an adjusting bolt arranged in the support barrel, wherein the upper part and the lower part of the support barrel are not equal in diameter; the top part of the adjusting bolt is positioned through a buckle cover with an opening; clamping grooves for hanging rope segments are arranged in the upper part of the support barrel; a rectangular buckle capable of being opened and closed is arranged on the side wall of the lower part of the support barrel; an annular clamping strip is arranged in the rectangular buckle and is meshed with the adjusting bolt; an adjusting rope is wound on the end surface of one side of the annular clamping strip; the annular clamping strip is driven to move through rotating the adjusting bolt to achieve adjustment of the rope length; and connection of the rope segments is achieved through rope grooves in the upper part of the support barrel. The device integrates connection and adjustment functions, and is simple to install; the profile accuracy of a reflecting metal wire mesh of the antenna can be effectively ensured; the function of adjusting the rope length can be achieved; the rope length adjustment range is large; and the operation is simple.
Description
technical field [0001] The invention relates to the field of deployable antennas with a cable-net reflecting surface, in particular to a cable segment connection and cable-length adjusting device for a satellite-borne cable-net reflective surface deployable antenna. Background technique [0002] With the development of science and technology, deployable antennas with cable-net reflectors, which are characterized by light weight, easy realization of large aperture, and small folded volume, have become an important development trend of spaceborne antennas. The structure form of the deployable antenna with cable net reflector is simple, and within a certain range, its structure form will not change with the increase of aperture, and its mass will not increase proportionally. It is an ideal structure form of large-scale deployable antenna. [0003] The deployable antenna with cable net reflector consists of five parts: front cable net, metal reflective wire mesh, adjustment cabl...
