Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil aviation low-voltage equipment technology, and in particular to a liftable side-light type FOD detection device. Background Technology
[0002] Existing edge-lamp FOD detection equipment can monitor airport runways, effectively reducing damage and property loss caused by FOD on the runway surface, thus ensuring safe takeoff and landing. Edge-lamp FOD detectors are installed vertically on the outer sides of the runway shoulders. Figure 1 As shown. Side-lamp FOD detection equipment technology should currently meet the relevant requirements in the advisory circular "Technical Requirements for Foreign Object Detection Equipment on Airport Pavements" (AC-137-CA-2024-01).
[0003] The edge-lit FOD detection equipment uses millimeter-wave radar to continuously scan a designated area to detect FOD, takes pictures of the scanned FOD locations, and reports the detected FOD information and images to the FOD management system. The background process further processes the images and identifies the type of FOD.
[0004] Current edge-light FOD detection equipment has the following problems during use: 1) According to current civil aviation industry standards, vertical equipment installed on runway shoulders should be lightweight and easily broken. Existing edge-light FOD detection equipment is installed on easily broken parts, so there is a probability that the equipment will be broken when aircraft wake blows over it; 2) Northern airports have snow removal needs during winter, and vertically installed edge-light FOD detection equipment may be broken by snowplows or directly struck by snowplows. Both of these situations can lead to the formation of new FOD, affecting flight safety and causing damage to airport equipment and property.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0026] This embodiment provides a retractable side-lamp type FOD detection device, such as... Figure 2 As shown, the equipment is in the retracted state. At this time, the equipment is not in operation, such as during takeoff and landing or snow removal. Figure 3 As shown, the equipment is in working condition, raising the side-lamp FOD detection device so that it is above the pavement 21.
[0027] like Figure 2 As shown, a liftable side-lamp FOD detection device mainly consists of a side-lamp FOD detector 1, a lifting assembly, and related cable installation accessories.
[0028] The edge-lamp FOD detector 1 has a prior art structure, mainly composed of a synthetic aperture millimeter-wave radar, an optical camera, a turntable, and a network switch. The millimeter-wave radar and optical camera are the core components of the edge-lamp FOD detector, performing continuous scanning of the runway surface 21 to detect FOD and reporting the detected FOD to the FOD management system. It should be noted that the structural description and operational process of the edge-lamp FOD detector 1 in this embodiment are only for those skilled in the art to understand the edge-lamp FOD detector 1; the actual structure and operation of the edge-lamp FOD detector 1 are not within the protection scope of this utility model.
[0029] The lifting assembly mainly consists of a top cover 2, a base 19, an equipment box 3, an electric rotary motor 12, a rotating telescopic rod 16, a lifting telescopic rod 17, a turntable 20, etc.
[0030] The top of the side-lamp type FOD detector 1 is flanged to the aluminum alloy top cover 2 via an upper flange and locked by locking component 6, which consists of galvanized bolts, caps, and gaskets. The aluminum alloy top cover 2 adopts an equal strength design and forging process, and can withstand internal pressure of 130 kPa or pressure generated by aircraft impact.
[0031] The bottom of the side-lamp type FOD detector 1 is flanged to the aluminum alloy base 19 via a lower flange 18 and locked by a locking component 7, which consists of stainless steel bolts, caps, and gaskets. The surface of the lower flange 18 is painted in aviation yellow.
[0032] Both the top cover 2 and the base 19 are threaded onto the inner wall of the aluminum alloy equipment box 3. The inner wall of the equipment box 3 has internal threads, while the top cover 2 and the base 19 have external threads, thus achieving a threaded fit. Furthermore, the base of the aluminum alloy equipment box 3 is designed with reinforcing ribs to enhance the load-bearing strength of the bottom of the equipment box 3.
[0033] The equipment box 3 is fixedly installed above the middle of the inner cavity of the concrete mounting shell 9. An opening is provided at the bottom of the equipment box 3, and a clip 14 is fixedly connected to this opening. The clip 14 abuts against the base 19, thereby restricting the downward movement of the base 19. The concrete mounting shell 9 is embedded below the pavement surface 21, with its top edge flush with the pavement surface 21.
[0034] An electric rotating assembly is connected to the bottom of the base 19, located below the middle of the inner cavity of the concrete mounting shell 9. Specifically, the electric rotating assembly includes an electric rotating motor 12, the output shaft of which is fixedly connected to a turntable 20. The bottom end of a lifting telescopic rod 17 is fixedly connected to the center of the turntable 20, and the top end of the lifting telescopic rod 17 is fixedly connected to the bottom of the base 19. The bottom ends of multiple rotating telescopic rods 16 are fixedly connected to the eccentric position of the turntable 20, and the top ends of the rotating telescopic rods 16 are fixedly connected to the bottom of the base 19. Both the lifting telescopic rod 17 and the rotating telescopic rod 16 adopt a two-section sleeve design. The two sections of the sleeve are grooved inside for a concave-convex fit. The two sections of the sleeve only slide relative to each other axially and do not rotate relative to each other circumferentially, ensuring that the two sections of the sleeve rotate synchronously during operation. In the retracted state, the two sections of the sleeve are nested together to save length space. During operation, the two sections of the sleeve are stretched to their maximum length, and a buckle 14 at the end prevents them from falling off when stretched to the limit.
[0035] The electric rotary motor 12 is powered by a constant current source and receives start and stop commands from the lifting controller 13. Upon receiving a start command, the electric rotary motor 12 drives the turntable 20 to rotate, causing the lifting telescopic rod 17 and the rotating telescopic rod 16 to rotate. The rotating telescopic rod 16 and the lifting telescopic rod 17 drive the base 19 and the top cover 2 to rotate and rise or fall along the internal threads of the equipment box 3, thus raising or lowering the side-lamp type FOD detector 1. The lifting controller 13 is connected to the upper-level management system via optical fiber 10, receiving start and stop control signals from the upper level and sending start and stop control signals to the electric rotary motor 12. It should be noted that the algorithms or programs involved in the above-mentioned operation process of the lifting controller 13 controlling the electric rotary motor 12 are all existing technologies and are only intended for those skilled in the art to understand the operation and control of the electric rotary motor 12.
[0036] The lifting telescopic rod 17 has a cable connection cavity inside for connecting the cable of the side-lamp type FOD detector 1.
[0037] A secondary cable protection pipe 5 and an optical fiber protection pipe 11 are fixedly installed at the bottom of the concrete mounting shell 9. The secondary cable protection pipe 5 penetrates the shell of the concrete mounting shell 9 and is used for the access of the secondary cable 4; the optical fiber protection pipe 11 penetrates the shell of the concrete mounting shell 9 and is used for the access of the optical fiber 10.
[0038] The total power consumption of the side-lamp FOD detector 1 and the electric rotary motor 12 does not exceed 200W, and can be powered by existing lighting isolation transformers on the market.
[0039] Both the electric rotary motor 12 and the side-lamp FOD detector 1 are electrically connected to the grounding jumper 8 to achieve grounding. The top of the concrete mounting shell 9 (i.e., the position near the pavement 21) is coated with a WEBER adhesive layer 15.
[0040] The working process of this embodiment will be further described below:
[0041] When the side-lamp type FOD detector 1 needs to work, the lifting controller 13 controls the electric rotary motor 12 to start, and the top cover 2 and the base 19 rotate and rise along the inner wall thread of the equipment box 3 until the two sleeves of the rotating telescopic rod 16 and the lifting telescopic rod 17 are stretched to the limit. At this time, the upper edge of the base 19 is flush with the pavement 21, and the lower flange 18 painted with aviation yellow protrudes from the ground.
[0042] When there is takeoff or landing or snow removal, the lifting controller 13 controls the electric rotary motor 12 to reverse, and the top cover 2 and the base 19 rotate and descend along the inner wall thread of the equipment box 3 until the top cover 2 is completely retracted. At this time, the upper edge of the top cover 2 is flush with the pavement 21.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model using the disclosed methods and techniques, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the shape, structure, and principle of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
