Automatic snow clearing method and device for satellite antenna

Abstract

The invention discloses an automatic snow clearing method and device for a satellite antenna, and belongs to the technical field of radio and television. The device comprises a main control unit, a power distribution box, an air energy storage device, an electric heating tape, a control contactor, a gas pressure conveying pipe, an ejector, a rotating angle mechanism, a rain and snow sensor, an outdoor temperature sensor, and an indoor temperature sensor. The method comprises the steps: adjusting and fixing the spatial position of the ejector; adjusting and locking the spatial position of the ejector again under the condition of snowfall; and carrying out the automatic snow clearing for the satellite antenna through employing the air energy storage device according to the information of the rain and snow sensor and the temperature sensor. The device employs an air compressor to store energy, and removes the un-falling and fallen snowflake through high-pressure air ejected by the ejector. The ejector is small in size, is light in weight, and can neglect wind resistance impact and signal loss. The device is convenient to install, does not need to reconstruct conventional equipment, and can fully meet the national demands for a satellite communication antenna snow clearing device.

Description

technical field [0001] The invention belongs to the technical field of radio and television, and in particular relates to a method and device for automatically clearing snow from a satellite antenna. Background technique [0002] Satellite communication has been widely used in important fields such as domestic wireless communication, international communication, and emergency communication. Users in industries such as radio and television, petroleum, electric power, banking, securities, and civil aviation have established their own dedicated satellite communication networks. Most satellite station ground stations are distributed in Northeast, Northwest, North China, Xinjiang and other regions, and undertake important services such as backup of communication backbone transmission lines, data distribution, content broadcasting and satellite signal transmission. [0003] The satellite communication antenna is an important equipment of the satellite ground station. It is a devic...
