Description

Technical Field

[0001] The present invention relates to the technical field of satellite antennas, and in particular to an anti-interference multi-band satellite antenna. Background Art

[0002] An anti-interference multi-band satellite antenna is an antenna designed to receive satellite signals and has anti-interference capabilities. This type of antenna usually has the ability to receive multiple frequency bands and can receive satellite signals of different frequencies. The anti-interference ability of this antenna is usually achieved through design and material selection. It can reduce the impact of external interference signals by using specially designed reflectors and polarizers. In addition, the structure and materials of the antenna can also help reduce the impact of interference.

[0003] After searching, the Chinese patent authorization number CN219937373U discloses a satellite antenna, including a satellite antenna body, an adjustment device and a mounting plate. The satellite antenna body is fixed on the mounting plate, and the mounting plate is driven by the adjustment device. The adjustment device includes a base, a motor, a ball screw, a fixing block and an L-shaped connecting rod. The ball screw is arranged on the base, and the screw of the ball screw is driven to rotate by the motor. The nut of the ball screw is hinged to one side of the mounting plate, and the fixing block is arranged at one end of the ball screw. The shorter end of the L-shaped connecting rod is hinged to the fixing block, and the longer end is hinged to the mounting plate. The above patents have the following deficiencies: the existing anti-interference multi-band satellite antenna is exposed outdoors or in the wild for a long time. Some open places, especially in some coastal areas, often have bad weather with wind and rain. Some rainwater is easy to accumulate in the satellite antenna, and some dust will stick to the antenna body to form a layer of mucous film, causing the signal of the satellite antenna to weaken. In addition, rainwater will absorb and scatter satellite signals, thereby reducing the signal strength and quality received by the antenna, which may cause signal interruption, blurred image or data transmission errors. Secondly, rainwater may form a water film on the surface of the antenna, change the impedance characteristics of the antenna, affect the matching and radiation efficiency of the antenna, and then affect the signal reception and transmission performance, and may even penetrate into the antenna, causing circuit short circuits and other hardware failures, and cannot automatically clean up the rainwater on the surface.

At the same time, the piston plate is reset The water is sucked into the piston cylinder from the cleaning barrel through the suction pipe, and then the connecting plate is driven to reset. When the half gear meshes with the full gear again, the cam contacts the connecting plate again, causing the push rod to push the piston plate again, so that the water in the piston cylinder is squeezed out from the outlet pipe into the nozzle, and the reciprocating operation is carried out to spray the water sucked into the piston cylinder onto the satellite antenna body. When the adjustment plate is adjusted to ninety degrees, the scraper will have a better effect when scraping and cleaning it, which can make the cleaning cleaner. By cleaning rainwater and dust in time, large-scale repairs or replacements required due to decreased antenna performance can be prevented, thereby saving maintenance costs.

The connecting plate 38 pushes the sliding rod 37, and the sliding rod 37 pushes the piston plate 31 to be squeezed in the piston cylinder 30. When the connecting plate 38 pushes the sliding rod 37, the spring 3701 is compressed. When the half gear 40 is not engaged with the full gear 42, the cam 43 no longer rotates, and the spring 3701 automatically causes the sliding rod 37 to pull the piston plate 31 to reset, and the piston When the plate 31 is reset, the water is sucked into the piston cylinder 30 through the suction pipe 36 from the cleaning barrel 35, and then the connecting plate 38 is driven to reset. When the half gear 40 is meshed with the full gear 42 again, the cam 43 is again in conflict with the connecting plate 38, so that the sliding rod 37 pushes the piston plate 31 again, so that the water in the piston cylinder 30 is squeezed out from the water outlet pipe 34 into the nozzle 33, and the reciprocating operation is performed, so that the water sucked into the piston cylinder 30 is sprayed onto the satellite antenna body 2.
