Description

Technical Field

[0001] This invention belongs to the field of satellite antenna technology, and in particular relates to a satellite antenna device installed on a mobile carrier. Background Technology

[0002] Satellite antennas, as core equipment for receiving or transmitting satellite signals, are widely used in fields such as communications, broadcasting and television, navigation and positioning, and meteorological monitoring. Shipborne satellite antennas are core equipment for ships to receive satellite signals at sea and realize communications (such as maritime satellite communications), navigation, or entertainment signal reception. For example, a shipborne satellite antenna is proposed in patent publication number CN106025512A.

[0003] In the marine environment, seabirds need to fly over the sea for a long time to forage and frequently look for stable "footholds" to rest. The antenna covers of ships are mostly smooth arc-shaped structures made of fiberglass or composite materials, and have the characteristics of being unobstructed and having a wide field of vision, which perfectly meet the needs of seabirds for "safe resting places", and therefore become their common resting areas.

[0004] Seabirds' droppings can significantly interfere with satellite signals: Firstly, wet or thickly accumulated bird droppings are high dielectric constant materials that can directly absorb or reflect satellite signals, causing a significant decrease in the signal strength received by the antenna. Secondly, dried bird droppings can form irregular hard lumps or particles that, when attached to the surface of the casing, can scatter satellite signals, causing the signal propagation direction to deviate from the antenna's receiving angle, further exacerbating the signal interference problem.

[0005] In addition, shipborne satellite antennas are usually installed 3-5 meters above the upper deck of the ship. During cleaning operations, personnel have to stand on a swaying platform to remove bird droppings, which is extremely risky and can easily lead to slipping or falling.

[0006] To address this issue, a satellite antenna device mounted on a mobile platform is proposed. Summary of the Invention

A sealing plate 25 and a sealing cover 26 are fixedly connected to the inner wall of the cleaning strip 24. The sealing plate 25 and the sealing cover 26 divide the interior of the cleaning strip 24 into a first sealing cavity 27, a second sealing cavity 28 and a third sealing cavity 29. The upper end of the fixed tube 23 is connected to the first sealing cavity 27. Multiple water spray holes 30 are opened on the inner wall of the cleaning strip 24.

[0036] The damage detection component 34 includes a small air pump 341 fixedly connected to the lower side wall of the connecting plate 4.

[0038] The operating principle of this invention is explained as follows: The satellite antenna body 5 is installed on the deck of a ship through the mounting cylinder 1. When the ship encounters sea winds during navigation, the controller 7 located above the connecting plate 4 will detect the direction of the sea wind through the wind direction sensor above the ship, and then control the rotating motor 3 to work. The rotating motor 3 will drive the mounting base 2 to rotate to the set angle. The mounting base 2 will drive the windshield 43 to rotate to the windward direction through the adjusting plate 81. The windshield 43 reduces the impact of the sea wind on the adjusting component 8. The waves blown by the sea wind will cause the ship to tilt slightly. The ship will cause the mounting cylinder 1 and the mounting base 2 to tilt together. The water tank 13 is filled with cleaning agent, which will cause the center of gravity of the adjusting component 8 to shift downward. The water tank 13 controls the connecting plate 4 and the satellite antenna body 5 to always remain in a vertical state through the vertical pipe 12 (applicable to sea waves caused by sea winds of level 5 and below). When the waves cause the ship to sway vertically, the satellite antenna body 5 only needs to be adjusted by a small angle to ensure that it is in the correct position, reducing the wear and tear on the components caused by frequent adjustments of the satellite antenna body 5.

[0039] When the satellite antenna body 5 is in normal operation, the controller 7 detects that the internal temperature of the housing 6 has risen to a set threshold (exceeding 65 degrees Celsius) through the temperature sensor inside the housing 6 (not shown in the figure). Then, the controller 7 will control the small water pump 15 to work and control the first control valve 17 to be in the open state. The small water pump 15 delivers the cleaning agent inside the water tank 13 to the outermost ring of the spiral water cavity 141 through the drain pipe 16. The cleaning agent will carry away the heat transferred by the spiral heat sink 142 and return to the water tank 13 through the return water pipe 18 in the inner ring of the spiral water cavity 141, thereby reducing the heat generated by the satellite antenna body 5 when it is in operation.

[0040] When bird droppings fall onto the surface of the housing 6 and obstruct the signal reception of the satellite antenna body 5, the satellite antenna body 5 sends an electrical signal to the controller 7. Upon receiving this signal, the controller 7 controls the small water pump 15 to operate, opens the second control valve 22 (while the first control valve 17 is closed), and opens the first regulating valve 33. The small water pump 15 pumps the cleaning agent inside the water tank 13 through the drain pipe 16 and the horizontal pipe 21 into the rotating ring 191, and then through the fixed pipe 23 into the first sealing cavity 27. The cleaning agent is then transported through the connecting pipe 32 to the third sealing cavity 29 and sprayed through multiple water jets. The nozzle 30 sprays water onto the surface of the housing 6. At the same time, the controller 7 controls the drive motor 20 to work. The drive motor 20 drives the rotating ring 191 to rotate through the gear ring transmission mechanism (the gear ring transmission mechanism includes a gear and a gear ring, the output end of the drive motor 20 is connected to the gear, the gear ring is sleeved on the surface of the rotating ring 191, and the drive motor 20 drives the gear ring and the rotating ring 191 to rotate together through the gear). The rotating ring 191 drives the cleaning strip 24 to rotate along the outside of the housing 6 through the fixed tube 23. The cleaning agent sprayed from the nozzle 30 wets the housing 6, and then the rubber strip 31 cleans the bird droppings attached to the surface of the housing 6.

[0041] Controller 7 performs a daily airtightness test on housing 6. Controller 7 controls the small air pump 341 and the first solenoid valve 342 to operate for three seconds (with the second solenoid valve 36 closed). The small air pump 341 delivers external gas into housing 6 and keeps housing 6 sealed for one hour (after which the gas can be released through exhaust pipe 35 by opening the second solenoid valve 36). The air pressure sensor 37 on the inner wall of housing 6 monitors the internal air pressure in real time. When controller 7 detects a pressure in housing 6 through the air pressure sensor 37... When the internal air pressure decreases, it indicates that the casing 6 has been damaged. The controller 7 will then activate the small water pump 15 to deliver cleaning agent into the first sealing chamber 27 (refer to the working principle described above). Simultaneously, the controller 7 will open the second regulating valve 42, allowing the cleaning agent to be delivered to the second sealing chamber 28 via the drain pipe 41. Furthermore, the cleaning agent will be delivered to the rubber sheet 39 via the pressure port 38, causing the rubber sheet 39 to expand and contact the outer surface of the casing 6. The controller 7 will then detect the damage to the second sealing chamber 28 via the hydraulic sensor 40. When the hydraulic pressure inside the sealed cavity 28 reaches the set threshold (50 kPa), the controller 7 will control the small water pump 15 to stop working and control the second control valve 22 to close. Then, the controller 7 will control the cleaning strip 24 to slowly rotate along the cover 6 and detect the air pressure inside the cover 6 through the air pressure sensor 37. When the controller 7 detects that the air pressure inside the cover 6 decreases or stops decreasing during the rotation of the cleaning strip 24, it means that the cleaning strip 24 has moved to the damaged area on the surface of the cover 6. The controller 7 will then control the cleaning strip 24 to stop moving and send this signal to the receiving end through the internal wireless communication module to remind the operators on the ship to repair the cover 6. The operators can determine the damaged area of ​​the cover 6 by observing the position where the cleaning strip 24 stops. Subsequently, the controller 7 will control the first regulating valve 33 to open, and the cleaning agent located inside the second sealed cavity 28 will be delivered to the first sealed cavity 27 through the drain pipe 41, and then delivered to the third sealed cavity 29 through the connecting pipe 32, and discharged through the spray hole 30 to restore the rubber sheet 39 to its original state.
