Description

Technical Field

[0001] The invention relates to the technical field of satellite communication maintenance, and in particular to a surface cleaning device for a flat-panel antenna. Background Art

[0002] The presence of snow or ice on the antenna panel can have a serious impact on the performance and reliability of the antenna. First, signal attenuation. Snow and ice absorb and scatter RF signals, resulting in weakened signal strength. Signal attenuation reduces the communication quality of the antenna and may cause data transmission errors, signal loss, or communication interruption. Second, frequency offset. Snow and ice covering the antenna will change the physical size and dielectric constant of the antenna, thereby affecting the resonant frequency of the antenna. Frequency offset will cause the operating frequency of the antenna to deviate from the design value, affecting the matching and efficiency of the antenna. Third, mechanical load. The weight of snow and ice will increase the mechanical load of the antenna panel. Excessive load may cause deformation of the antenna structure, damage to the bracket, or tipping of the antenna, and in severe cases, even physical damage to the antenna. Fourth, antenna surface contamination. Snow and ice may leave contaminants such as salt and dust after melting. Contaminants will corrode the antenna surface and affect the electrical and mechanical properties of the antenna. Summary of the invention

A mask film 24 is wound on the winding mechanism, and the mask film 24 is covered on the opening side of the antenna panel 11.

[0021] The connecting member includes a pair of mounting plates 2 mounted on the outer wall of the antenna panel 11, an end plate 20 is provided at the outer end of the mounting plate 2, a side strip 21 is provided at the outer end of the end plate 20, the side strip 21 is located on the inner side of the mask film 24 to support the mask film 24, a limiting groove 22 is provided on the side strip 21, the mask film 24 is located in the limiting groove 22, a support roller rod 23 is rotatably provided between the end plates 20, the support roller rod 23 is located on the inner side of the support roller rod 23, and is used to support the inner side of both ends of the mask film 24. An inclined plate 29 is provided between the end plates 20, a scraper 30 is provided at the upper end of the inclined plate 29, and the blade of the scraper 30 acts on the outer wall of the mask film 24.

[0022] The winding mechanism includes a winding shaft 25 rotatably arranged on the end plate 20, and the two ends of the mask film 24 are respectively arranged on the winding shaft 25. One end of each winding shaft 25 is provided with a synchronous wheel 26, and the synchronous wheels 26 are driven by a synchronous belt 27. The other end of one of the winding shafts 25 is connected to a motor 28, and the motor 28 is installed on the end plate 20. A limiting circular sleeve 31 is installed between the end plates 20, and a notch 32 is opened on the limiting circular sleeve 31. The mask film 24 is inserted in the notch 32. A connecting plate 34 is arranged on the outer periphery of the limiting circular sleeve 31. A scraper 35 is arranged at the outer end of the connecting plate 34.
