Abstract
Description
Technical Field
[0001] This invention belongs to the field of production technology of airport navigation station control equipment, and specifically relates to a centralized control device for airport navigation stations. Background Technology
[0002] Airport navigation beacons are ground stations that determine the position of aircraft and guide them along predetermined routes. They utilize the propagation characteristics of radio waves to measure navigation parameters (azimuth, distance, and speed), calculate deviations from the prescribed route, and allow pilots or autopilots to correct these deviations and maintain the correct course. Centralized control devices for airport navigation beacons are systems for monitoring, remotely controlling, and maintaining airport equipment. They primarily achieve centralized control, maintenance, and monitoring of navigation equipment, remote real-time monitoring of environmental information such as temperature, humidity, smoke, and infrared radiation within the beacon station, as well as video camera data, and remote management of power supplies and air conditioning within the station. Ultimately, this enables unmanned operation of airport navigation beacons.
[0003] The core electronic device of an airport navigation beacon centralized control system is the signal processor. To better protect the signal processor and prevent damage from rainwater intrusion, traditional airport navigation beacon centralized control systems typically have a mechanical protective structure around the signal processor, commonly a fence. For example, utility model patent with publication number "CN220476108U" discloses an airport navigation beacon centralized control system. The fence of this device protects the signal processor, and the cover plate is easily disassembled through the cooperation of slots and levers, facilitating later maintenance and equipment adjustment. The included drainage column guides rainwater into a collection tank, from which it is discharged through a drainage channel, giving the equipment advantages such as waterproofing and impact resistance.
[0004] However, during long-term use, the fences of the aforementioned traditional airport navigation station centralized control devices cannot block fine particles such as sand and dust. Sand and dust can enter the fence through gaps and adhere to the signal processor, affecting its heat dissipation and normal operation, thereby reducing its signal transmission efficiency. At the same time, in the high temperatures of summer, the air circulation inside the fence is relatively poor, and heat is easily accumulated, causing the internal temperature of the signal processor to be too high, accelerating the aging of electronic components, and even potentially causing component failure. Summary of the Invention

[0023] To improve efficiency and facilitate assembly, a first transmission rack 23, an air compressor box 18, a first piston plate 30, and a compression spring 29 together form an air compressor unit. The transmission device includes two air compressor units, which are located on opposite sides of the second transmission gear 22. The first transmission racks 23 of the two air compressor units are respectively meshed with the second transmission gear 22. The air outlet control motor 24 is located between the two first transmission racks 23 and is installed in the control box 5 through the mounting plate 25.
[0024] To further improve cleaning and heat dissipation by different air blowing directions from multiple air outlets, the transmission device also includes a fourth transmission gear 36 and a fifth transmission gear 37. In each column 4, the air outlet includes a first air outlet 17 and a second air outlet 15, and the connecting pipe includes a first connecting pipe 35 and a second connecting pipe 34. Multiple first connecting pipes 35 and multiple second connecting pipes 34 are respectively installed on opposite sides of the cavity wall of the column 4, and the number of them is the same. Multiple first air outlets 17 are respectively connected to the outer ends of multiple first connecting pipes 35, and multiple second air outlets 15 are respectively connected to the outer ends of multiple second connecting pipes 34. A third transmission gear 33 is fitted on the outside of all first connecting pipes 35, and a fourth transmission gear 36 is also fitted on the outside of all first connecting pipes 35.

Multiple fourth transmission gears 36 and multiple fifth transmission gears 37 are respectively meshed and connected. The air outlets on the first air outlet 17 and the second air outlet 15 are respectively located on the pipe wall.
[0025] To facilitate reliable air pressure transmission, the connecting crossbar 14 is a hollow bar, the connecting outer ring 10 is a hollow ring, the inner cavity of the hollow connecting seat 12 is connected to the inner cavity of the connecting outer ring 10 through multiple connecting crossbars 14, and the inner cavity of the connecting outer ring 10 is connected to the sliding inner cavity 31 of multiple columns 4.
[0026] To facilitate drainage, multiple drainage channels 8 are provided on the top plate 1. The bottom surface of the drainage channel 8 has an angle of 1°-20° with the horizontal direction, and one end near the edge is lower than the other end.
[0027] To achieve better cleaning function, a soft brush 16 is installed on the side of the column 4 near the signal processor 7, and the soft brush 16 is in contact with the outer wall surface of the signal processor 7.
[0028] To facilitate assembly, multiple positioning sleeves 9 are installed on the upper part of the base plate 3 near the edge, and the lower ends of multiple support columns 6 are connected to multiple positioning sleeves 9 respectively; to achieve better protection, multiple transverse protective plates 2 are installed between two adjacent support columns 6.
[0029] like Figures 1-5 As shown, during operation, the air pump 13 runs, sending high-pressure gas to all the connecting pipes and blowing it out through the air outlet of the corresponding air outlet pipe onto the outer wall surface of the signal processor 7, forming a continuous high-pressure airflow to clean and cool the outer wall surface of the signal processor 7.
[0030] The exhaust control motor 24 operates, driving the transmission turntable 27 to rotate. The turntable gear 28 on the transmission turntable 27 drives the first transmission gear 26 to rotate. The first transmission gear 26 drives the transmission connecting rod 20, the second transmission gear 22, the hollow connecting seat 12, the connecting crossbar 14, the connecting outer ring 10, multiple columns 4, all connecting pipes, and the exhaust pipe to rotate horizontally synchronously, expanding the air blowing coverage area. At the same time, the second transmission gear 22 drives the two first transmission racks 23 to move, pushing the first piston plate 30 to move against the elastic force of the compression spring 29. This compresses the air in the inner cavity of the air compressor box 18 containing the compression spring 29 and delivers it to the hollow connecting seat 12 through the second air pipe 19. Then, it is transported through the connecting crossbar 14 and the connecting outer ring 10. The air is conveyed into the sliding inner cavity 31 of multiple columns 4, pushing the second piston plate 32 to move downward, thereby driving the second transmission rack 38 to move downward. Through the third transmission gear 33, all the first connecting pipes 35 and the first air outlet pipes 17 rotate vertically, and all the air outlets of the first air outlet pipes 17 rotate vertically. At the same time, with the cooperation of the fourth transmission gear 36 and the fifth transmission gear 37, all the second connecting pipes 34 and the second air outlet pipes 15 rotate vertically in opposite directions, and all the air outlets of the second air outlet pipes 15 rotate vertically in opposite directions. This significantly expands the coverage of the airflow, improves the comprehensiveness and effect of dust removal and cooling, and further effectively removes dust from various parts of the outer wall surface of the signal processor 7 and removes heat.
[0031] When the transmission turntable 27 rotates to the area where there is no turntable gear 28 meshing with the first transmission gear 26, the transmission turntable 27 and the first transmission gear 26 cannot transmit power. Under the combined action of the reset torsion spring 21 and the compression spring 29 (mainly the action of the reset torsion spring 21), the transmission connecting rod 20, the first transmission gear 26, the second transmission gear 22, the hollow connecting seat 12, the connecting crossbar 14, the connecting outer ring 10, the multiple columns 4, all the connecting pipes and the air outlet pipes synchronously rotate in the opposite direction to reset. All the air outlet pipes complete one horizontal rotation cycle. Simultaneously, the first transmission rack 23 and the first piston plate 30 move in opposite directions to reset, increasing the volume of the inner cavity of the air compressor box 18 equipped with the compression spring 29. The compressed air in the sliding inner cavity 31 of the multiple columns 4 flows back through the connecting outer ring 10, connecting crossbar 14, hollow connecting seat 12 and the second air pipe 19, causing the second piston plate 32 to move upward to reset, thereby driving the second transmission rack 38 to move upward. Through the third transmission gear 33, all the first connecting pipes 35 and the first air outlet pipes 17 rotate in opposite directions to reset, and all the air outlets of the first air outlet pipes 17 rotate in opposite directions to reset. At the same time, with the cooperation of the fourth transmission gear 36 and the fifth transmission gear 37, all the second connecting pipes 34 and the second air outlet pipes 15 rotate in opposite directions to reset, and all the air outlets of the second air outlet pipes 15 rotate in opposite directions to reset. All the air outlet pipes complete one vertical rotation cycle.
[0032] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the technical solutions of the present invention. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
