Abstract

The invention discloses an auxiliary reflecting plane integrated with a support arm. The auxiliary reflecting plane comprises an auxiliary reflecting plane body and a feed source support arm, wherein the feed source support arm is positioned on one side of the auxiliary reflecting plane body, the auxiliary reflecting plane body is integrated with the feed source support arm, a front face of the feed source support arm is provided with feed source horn interfaces, side faces of the feed source support arm are provided with pneumatic support rod interfaces and rotary table interfaces, the auxiliary reflecting plane body and the feed source support arm are made of carbon-fibre composite materials, a thin wall structure or a sandwich composite material structure is adopted for the auxiliary reflecting plane body, and the thin wall structure or the sandwich composite material structure is adopted for the feed source support arm. The auxiliary reflecting plane is simple in structure, and the feed source support arm serves as a reference for installation in working processes; main reflecting plane, auxiliary reflecting plane body and feed source horn assembling and setting workloads can be greatly reduced; auxiliary reflecting plane body and horn positioning accuracy is improved, weight is reduced, high consistency is realized, and size stability and environment adaptability are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of reflective surfaces, in particular to an arm fusion type secondary reflective surface. Background technique [0002] The satellite antenna sub-reflector is one of the key components of the antenna feed distribution system in the satellite communication system. The traditional carbon fiber satellite antenna sub-reflector and feed support arm, the feed support arm is made of aluminum alloy, and the feed support arm and the sub-reflector are connected by screws. In addition, the feed support arm needs to be installed Source speakers and other components. In order to ensure the relative positional relationship between the main reflector, the sub-reflector and the feed horn, a complex adjustment mechanism is required. Moreover, both the main reflector and the sub-reflector are made of carbon fiber composite material, which is quite different from the traditional aluminum alloy feed support arm material in te...
