Description

Technical Field

[0001] This utility model relates to the field of receiving equipment technology, and in particular to an ADS-B receiving device. Background Technology

[0002] Automatic Dependent Surveillance (ADS) is a surveillance technology recommended by the International Civil Aviation Organization (ICAO) for next-generation air traffic control systems. It refers to the automatic, real-time transmission of navigation information obtained by the airborne navigation system to a ground receiving and processing system via satellite data link or VHF air-to-ground data link. The system then provides pseudo-radar images through display devices for ground monitoring of aircraft operational status. ADS-B receivers, combined with air traffic control systems and other aircraft's onboard ADS-B systems, provide accurate and real-time conflict information both in the air and on the ground. Most ADS-B receivers use directional antennas.

[0003] For example, Chinese utility model patent (CN212163312U) discloses an ADS-B receiving device, which states: "Through the combined use of a motor, an electric telescopic rod, and a universal ball connector, the antenna device can be assisted in turning. Under the action of the motor, the antenna device can perform circumferential motion, and under the action of the electric telescopic rod, the antenna device can perform pitch motion. The angle of the antenna can be adjusted according to the needs, which improves the flexibility of the antenna in receiving signals from different directions."

[0004] However, antenna receiving equipment needs to be kept free of debris such as branches and weeds on its surface during daily operation to avoid affecting the quality of antenna reception and signal transmission. The aforementioned receiving equipment does not have the relevant cleaning function, which requires staff to perform regular maintenance and repairs, which is time-consuming and labor-intensive. Therefore, this application proposes an ADS-B receiving device. Utility Model Content

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1:

[0030] Please refer to Figure 1-4 An ADS-B receiving device includes a housing 1, with a main unit 2 installed inside the housing 1. An antenna dish 3 and an antenna body 4 are respectively installed at the top of the housing 1. When the device is used outdoors, and the outside of the antenna body 4 accumulates branches, weeds, and other debris during daily use, and the inside of the antenna dish 3 accumulates water, the following measures are taken to facilitate automated, periodic cleaning and maintenance:

[0031] A support shaft 5 is rotatably connected to the upper end of the housing 1 near the antenna body 4. A mounting frame 6 is fixed to the outside of the support shaft 5. A support cylinder 10 is rotatably connected to the inner side of the mounting frame 6 away from the support shaft 5.

A soft scraper 17 is fixed to the end of each scraper seat 16 near the antenna dish 3. The soft scraper 17 is in contact with the inner side of the antenna dish 3.

[0032] In order to facilitate the control of the rotation of the support shaft 5 and thus drive the mounting frame 6 to flip, so that the cleaning inner cylinder 15 can be aligned with the axis of the antenna body 4, a first drive assembly is provided between the box 1 and the support shaft 5.

[0033] Specifically, the first drive assembly includes a first motor 8, the first motor 8 is fixed at the upper end of the housing 1 near the support shaft 5, the output end of the first motor 8 is fixed with a second bevel gear 9, the outer side of the support shaft 5 is fixed with a first bevel gear 7, and the first bevel gear 7 and the second bevel gear 9 are meshed and connected.

[0034] In order to drive the cleaning inner cylinder 15 to move closer to the antenna dish 3 and the antenna body 4, thereby moving multiple rubber rake teeth 19 to the outside of the antenna body 4 and multiple soft scrapers 17 to fit against the inside of the antenna dish 3, a third drive assembly is provided between the support cylinder 10 and the threaded sleeve 14.

[0035] Specifically, the third drive assembly includes a third motor 21, which is fixed inside the support cylinder 10 and outside the threaded sleeve 14. A third spur gear 22 is fixed at the output end of the third motor 21. An external gear ring 20 is fixed on the outer side of the threaded sleeve 14 away from the support cylinder 10. The external gear ring 20 is meshed with the third spur gear 22.

[0036] When the threaded sleeve 14 rotates, in order to limit and guide the cleaning inner cylinder 15 and ensure that the cleaning inner cylinder 15 can move, each wiper seat 16 is fixed with a guide post 18 at the end away from the soft scraper 17. The end of the guide post 18 away from the wiper seat 16 passes through the support cylinder 10 and is slidably connected to the support cylinder 10.

[0037] Before, during and after the inner cleaning cylinder 15 moves, in order to drive the inner cleaning cylinder 15 to rotate, so that multiple rubber rake teeth 19 can be used to clean the outer surface of the antenna body 4, and when the soft scraper 17 is attached to the inner side of the antenna dish 3, it can scrape off the water accumulated on the inner wall of the antenna dish 3.

[0039] Example 2:

[0040] The ADS-B receiving device provided in Embodiment 1 is further optimized. All the above-mentioned electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. The existing publicly disclosed power connection technology will not be described in detail here. This is to realize the function of controlling the above-mentioned electrical components to periodically and automatically clean and maintain the antenna dish 3 and the antenna body 4. Furthermore, the mechanical transmission components provided in this utility model are all closed designs that can be opened for maintenance. According to the mechanical manual, as long as they are properly maintained, these mechanical transmission components can normally realize the transmission movement claimed above.

[0041] The usage process of the ADS-B receiving device provided by this utility model is as follows: whenever the preset time for cleaning and maintenance of the antenna dish 3 and the antenna body 4 is reached, the first motor 8 is automatically started to drive the second bevel gear 9 to rotate. By using the meshing of the second bevel gear 9 and the first bevel gear 7, the support shaft 5 is rotated 180 degrees, which in turn drives the mounting frame 6 to flip to the upper end of the box 1, so that the cleaning inner cylinder 15 is aligned with the axis of the antenna body 4.

[0042] After the mounting frame 6 has been flipped, the first motor 8 is stopped and the third motor 21 is started to drive the third spur gear 22 to rotate. The meshing of the third spur gear 22 with the external gear ring 20 drives the threaded sleeve 14 to rotate. The threaded connection between the threaded sleeve 14 and the cleaning inner cylinder 15, along with the sliding guidance of the guide post 18 and the support cylinder 10, drives the cleaning inner cylinder 15 to move closer to the antenna body 4. During the movement of the cleaning inner cylinder 15, the second motor 12 is started to drive the second spur gear 13 to rotate. The meshing of the second spur gear 13 with the first spur gear 11 drives the support cylinder 10 to rotate, so that the cleaning inner cylinder 15 can rotate while moving.

[0043] Once the cleaning inner cylinder 15 moves to the outside of the antenna body 4 and the soft scraper 17 is in contact with the inside of the antenna dish 3, the third motor 21 is stopped. At this time, the rotation of the cleaning inner cylinder 15, in conjunction with multiple rubber rake teeth 19, cleans the debris such as branches and weeds accumulated on the outer surface of the antenna body 4. At the same time, the contact between the soft scraper 17 and the antenna dish 3 removes the water accumulated on the inner wall of the antenna dish 3. After cleaning for a period of time, the cleaning inner cylinder 15 is moved back to its original position. At this time, the debris on the outer surface of the antenna body 4 is collected inside the cleaning inner cylinder 15 by the multiple rubber rake teeth 19. The mounting frame 6 is then flipped back to its original position, completing the automated cleaning and maintenance work for the antenna dish 3 and the antenna body 4.
