Automatic cleaning type satellite antenna

Abstract

The invention discloses an automatic cleaning type satellite antenna. The automatic cleaning type satellite antenna comprises a mounting stand column; a parabolic panel is arranged above the mountingstand column; feed source support rods are inwardly and upwardly arranged on the circumferential side of the parabolic panel in an inclined manner; a feed source is fixedly arranged at the top ends ofthe feed source support rods; a water leakage hole is formed in the center of the parabolic panel; a panel angle adjustment apparatus is connected between the mounting stand column and the parabolicpanel; a panel cleaning apparatus is arranged in the water leakage hole; a cleaning power apparatus is fixedly mounted at the top end of the mounting stand column; the power output end of the cleaningpower apparatus is in transmission connection with the panel cleaning apparatus; by virtue of the panel angle adjustment apparatus, the inclination angle of the parabolic panel can be changed; the panel cleaning apparatus, under driving of the cleaning power apparatus, can perform automatic cleaning on the surface of the parabolic panel to remove dust, frost and snow and the like from the surface; and human intervention is not needed in the cleaning process, and instead, the cleaning process is automatically completed in a force-saving and convenient and efficient manner, thereby facilitatingguarantee of satellite signal effective receiving.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a satellite antenna capable of automatically cleaning surface dust. Background technique [0002] The satellite receiving antenna uses a metal parabola to reflect the satellite signal to the feed source and high frequency head at the focal point, so as to receive the weak signal from the satellite and remove the noise as much as possible during the receiving process. Considering factors such as cost and installation, the metal parabola of the satellite receiving antenna has different apertures. Generally speaking, the larger the antenna aperture, the stronger the program signal and the higher the reception quality. [0003] The satellite receiving antenna has been exposed to the outside environment for a long time. Due to the influence of the environment in the place of use, the surface of the metal parabola is prone to be covered with dust or frost, which will affect ...

Problems solved by technology

[0003] The satellite receiving antenna has been exposed to the outside environment for a long time. Due to the influence of the environment in the place of use, the surface of the metal parabola is prone to be covered with dust or frost, which will affect the effect of signal reception. Therefore, it is necessary to clean the metal parabola regularly. Because the diameter of the metal parabola is also The size is different. It is relatively simple to clean small-diameter metal paraboloids, which can be cleaned manually with a rag. For large-diameter metal paraboloids, due to the limited arm length, manual cleaning is inconvenient and the cleaning efficiency is low. Therefore, it is necessary to clean the satellite. The receiving antenna is further improved to avoid the above defects
