Embodiment Construction

[0014] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0015] The present invention takes a 2.4-meter satellite antenna reflector skeleton as an example.

[0016] Such as Figure 1-Figure 2 , a 2.4-meter satellite antenna reflector skeleton, comprising a web 1 and a central cylinder 2, the web 1 is made by punching a plate. The central cylinder 2 is sand blasted to derust the surface first, and then hot sprayed with zinc, the thickness of the zinc sprayed layer is ≥ 1 mm; the surface of the spoke plate 1 is coated with a galvanized layer, and the thickness of the galvanized layer is ≥ 12 μm. After the surface treatment of the galvanized or galvanized process, painting can be carried out. There are 8 spoke plates 1; they are respectively connected and fixed on the central tube 2 by bolts to form the skeleton of the satellite antenna reflector, and the 8 spoke plates are identical in shape and size, and th...

Abstract

The invention relates to a reflector frame of a satellite antenna. The reflector frame of the satellite antenna comprises a central cylinder and a plurality of radial plates. The radial plates are respectively connected to the central cylinder through bolts. Each radial plate is made of a plate in a stamping mode. Firstly, sand is sprayed on the surface of the central cylinder so that rust can be eliminated; secondly, hot zinc spray is conducted on the central cylinder, wherein the thickness of a sprayed zinc layer is larger than or equal to 1mm; thirdly, the surface of each radial plate is coated with a zinc coating, wherein the thickness of each zinc coating is larger than or equal to 12 micrometers. The reflector frame of the satellite antenna has the advantages of being low in cost, light in weight, simple and rapid in machining, and convenient to install.

Description

technical field [0001] The invention relates to a reflector skeleton of a satellite antenna, which belongs to the field of satellite communication equipment. Background technique [0002] The antenna reflector skeleton is the main stress body and structural support of the entire antenna reflector. With the diversification of satellite antennas, there are various types of reflector skeletons. But most reflector frames are not only heavy but also complicated to install. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide a reflector skeleton of a satellite antenna with small weight, simple processing and convenient installation. [0004] The present invention adopts the following technical solution: a reflector skeleton of a satellite antenna, which is characterized in that it includes a central cylinder and several webs, and the several webs are respectively connected to the central cylinder ...
