Description

Technical Field

[0001] This utility model relates to the field of airport foreign object detection technology, and in particular to a novel airport pole-mounted FOD detection device. Background Technology

[0002] FOD (Foreign Object Debris) detection systems play a crucial role in ensuring airport operational safety. Currently, common FOD detection systems mainly fall into two categories: edge-lamp detection devices and tower-type detection devices. These traditional systems face several technical and application bottlenecks in airport applications.

[0003] On the one hand, due to airspace clearance requirements in flight zones, many airports cannot meet the installation space and structural conditions required to build tower-type detection systems, making it impossible to deploy such systems at most airports. On the other hand, although edge-light FOD detection systems are easy to install in the runway edge area, they are easily buried by ice and snow in extreme weather conditions such as cold and snow, making the equipment easily damaged, with low reliability and high maintenance costs. At the same time, the construction period for edge-light systems in the renovation of existing runways is long, with risks of project delays and construction safety.

[0004] In addition, both side-lamp and tower-type FOD detection equipment have complex structures and high costs. Furthermore, the large number of devices deployed further exacerbates the cost pressure of system construction and subsequent operation and maintenance. In particular, the promotion and application of traditional detection systems are greatly limited during the renovation of old airport runways.

[0005] Therefore, there is an urgent need for a new type of airport pole-mounted FOD detection device that is simple in structure, low in cost, flexible in deployment, and highly adaptable. This device should be able to adapt to different airport site environmental conditions, achieve all-weather high-precision FOD target monitoring and early warning, and improve airport operational safety and the universality and practicality of FOD detection. Utility Model Content

[0006] To address the shortcomings of the existing technologies, this utility model provides a novel airport pole-mounted FOD detection device, aiming to solve the problems of difficulty in balancing rapid deployment and high-precision detection, poor equipment operational stability, and high maintenance costs in the existing technologies.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a novel airport pole-mounted FOD detection device, comprising a pole, a main body disposed at the upper end of the pole, a foldable structure disposed at the bottom end of the pole, and a detection and control module assembly disposed within the main body. The foldable structure includes a base plate disposed at the bottom end of the pole, a limiting clamp sleeved on the outer periphery of the pole, a pre-cut groove circumferentially opened at the lower part of the pole, limiting holes symmetrically opened on the pole, and a device that radially passes through the limiting clamp and inserts into the limiting holes. The connecting fasteners inside the pole have a pre-cut groove located above the limiting clamp, which is set on the base plate. When the horizontal impact torque on the pole exceeds a set threshold, a controllable fracture occurs at the pre-cut groove. After the pole breaks, it slides and tilts along the outside of the limiting clamp in the impact direction. The pole has a magnetic coupler inside, which consists of a pair of magnetic terminals. When the pole breaks, the magnetic terminals lose contact due to the increased distance between them, causing the circuit inside the pole to be disconnected.

[0008] Based on the above structural design, this utility model, through the combination of a pre-cut groove and a limiting clamp at the bottom of the pole, achieves controllable fracture of the structure when subjected to vehicle collisions or other external impacts, preventing the pole from collapsing randomly and causing equipment damage or personal injury, thus improving safety. When the pole breaks at the pre-cut groove, the internal magnetic coupler immediately disengages, thereby automatically cutting off the power to the circuit. This facilitates timely detection of abnormal states by the back-end system, which is beneficial for subsequent alarm and maintenance. In addition, the device integrates detection, control, and power supply modules within the main body at the top of the pole, resulting in a compact structure, convenient installation, good anti-interference capabilities, and environmental adaptability, making it suitable for the complex outdoor operating environment of airports.

[0009] Furthermore, the magnetic coupler is disposed inside the upright and located at the position corresponding to the pre-cut groove, and the magnetic terminals are respectively fixed on the fracture end faces opposite each other in the axial direction of the upright.

[0010] Based on the above, the magnetic coupler is installed in the inner cavities on the upper and lower sides of the pre-cut groove inside the pole. The magnetic terminals are respectively fixed to the fracture end faces opposite to each other in the axial direction of the pole. When the pole breaks at the pre-cut groove due to external force, the magnetic terminals will automatically disengage due to the increased spacing, thus automatically disconnecting the circuit. This structural design not only ensures timely power interruption when the structure is damaged, preventing false transmission of fault signals, but also provides clear power-off feedback for subsequent fault detection and maintenance, further improving the safety and intelligence level of the system.

[0011] Furthermore, the detection and control module assembly includes an optoelectronic module, an antenna module, a control module, and a power supply module. The optoelectronic module, the antenna module, and the control module are electrically connected, and the power supply module supplies power to the optoelectronic module, the antenna module, and the control module.

[0012] Based on the above, the detection and control module components achieve collaborative operation between various functional modules through electrical connections. The photoelectric module enables real-time monitoring of foreign objects, the antenna module is used for wireless signal transmission and reception, the control module undertakes data processing and logic control functions, and the power supply module provides stable power to the entire system. This structure realizes the integration and intelligence of FOD detection functions, improves the system's response speed and operational stability, and meets the actual needs of airports for efficient identification and timely alarm of foreign objects.

[0013] Furthermore, the magnetic coupler is fitted with a retractable corrugated tube.

[0014] Based on the above, the retractable corrugated tube is fitted outside the magnetic coupler, which can provide deformation compensation space for the internal cables when the pole breaks in a controlled manner, effectively buffering the tensile impact and preventing the cables from being damaged due to stress concentration at the moment of breakage, thereby further improving the electrical connection reliability and structural protection capability of the entire device in the event of a sudden collision or tipping.

[0015] Furthermore, the surface of the pole is provided with a base layer made of matte aluminum alloy and sprayed with a layer of red and white reflective paint.

[0016] Based on the above, the base layer made of matte aluminum alloy can effectively reduce interference caused by light reflection and reduce glare caused by direct sunlight, while the red and white reflective paint layer improves the visibility and warning effect of the pole in complex airport environments, which helps to improve operational safety and reduce the risk of collisions caused by obstructed vision or changes in light.

[0017] Furthermore, the front end face of the main body is provided with a first opening and a second opening. The first opening is provided with a photoelectric cover made of light-transmitting material, and the second opening is provided with a radar cover made of electromagnetic wave-transmitting material. The photoelectric cover and the radar cover are respectively fixedly connected to the main body by screws.

[0018] Based on the above, the photomask is integrally molded from tempered glass or high-transmittance acrylic material, and its surface can be coated with an anti-reflection coating to improve the transmission performance of visible and infrared light bands. The radar dome is made of polytetrafluoroethylene (PTFE), glass fiber reinforced resin (FR-4), or polycarbonate (PC) material with stable dielectric constant and low loss, so as to ensure low loss and stable wave transmission performance when millimeter wave and microwave frequency band signals penetrate.

[0019] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. Attached Figure Description

The flexible structure 3 includes a base plate 30 disposed at the bottom end of the pole 2, a limiting clamp 31 sleeved on the outer periphery of the pole 2, a pre-cut groove 32 circumferentially opened at the lower part of the pole 2, limiting holes 34 symmetrically opened on the pole 2, and a connecting clamp that passes radially through the limiting clamp 31 and inserts into the limiting hole 34. Firmware 33, the pre-cut groove 32 is located above the limiting clamp 31, the limiting clamp 31 is set on the base plate 30, when the horizontal impact torque of the upright 2 exceeds the set threshold, a controllable fracture occurs at the pre-cut groove 32, after the upright 2 breaks, it slides and tilts along the outside of the limiting clamp 31 in the impact direction, the upright 2 is provided with a magnetic coupler 5 inside, the magnetic coupler 5 is composed of a pair of magnetic terminals, when the upright 2 breaks, the magnetic terminals lose contact due to the increased distance between them, so that the circuit inside the upright 2 is in a disconnected state.

[0022] The magnetic coupler 5 is disposed inside the upright 2 and located at the position corresponding to the pre-cut groove 32, and the magnetic terminals are respectively fixed on the fracture end faces of the upright 2 opposite to each other in the axial direction.

[0023] The detection and control module assembly 4 includes an optoelectronic module 40, an antenna module 42, a control module 43, and a power module 44. The optoelectronic module 40, the antenna module 42, and the control module 43 are electrically connected, and the power module 44 supplies power to the optoelectronic module 40, the antenna module 42, and the control module 43.

[0024] The magnetic coupler 5 is fitted with a retractable corrugated tube 46.

[0025] The surface of the pole 2 is provided with a base layer made of matte aluminum alloy and sprayed with a layer of red and white reflective paint.

[0026] The front end face of the main body 1 is provided with a first opening and a second opening. A photoelectric cover 10 made of light-transmitting material is provided on the first opening, and a radar cover 11 made of electromagnetic wave-transmitting material is provided on the second opening. The photoelectric cover 10 and the radar cover 11 are respectively fixedly connected to the main body 1 by screws.

[0027] In summary, the specific embodiments of this utility model are as follows: In practical applications, the pole 2 of the device is made of high-strength aluminum alloy material, which has good corrosion resistance and structural stability. It is suitable for long-term outdoor deployment in the complex environment of airports. The bottom end of the pole 2 is mechanically fixed to the airport ground structure through the base plate 30, and the installation is firm and reliable.

[0028] The pre-cut groove 32 is precisely opened through machining during the manufacturing stage. Its position and depth are optimized to ensure that a controllable fracture occurs when the external impact reaches a set level, thereby achieving buffering and energy release against sudden collisions or abnormal external forces, and protecting the upper photoelectric system and core control module from damage.

[0029] The limiting clamp 31 is sleeved on the outer periphery of the bottom end of the upright 2, located below the pre-cut groove 32. The limiting clamp 31 has a ring or semi-ring structure and is fixedly connected to the base plate 30 by the connecting fastener 33. When the upright 2 is subjected to an external force impact and undergoes a controllable fracture along the pre-cut groove 32, the limiting clamp 31 provides positional constraint on the lower upright segment after the fracture, keeping it within a predetermined area above the base plate 30, thereby preventing the fractured segment from excessively slipping or completely detaching from the base plate 30. This structure ensures that the upright 2 has a flexible performance while maintaining the overall stability of the bottom structure and a controllable tilting path, improving the safety performance and maintainability of the device under impact conditions.

[0030] The magnetic coupler 5 is installed inside the pole, with its position corresponding to the upper and lower inner cavities of the pre-cut groove 32. It is installed in the inner wall before and after the breakage. When the pole breaks due to external force, a pair of magnetic terminals in the magnetic coupler will naturally disconnect due to the increased relative distance, thereby interrupting the circuit, quickly cutting off the power supply signal, effectively ensuring the power-off state of the detection system, preventing false alarms, and providing fault location basis for later maintenance.

[0031] The retractable corrugated tube 46 is sleeved on the outside of the magnetic coupler 5. It is made of flexible flame-retardant rubber or UV-resistant plastic material and has good expansion and rebound performance. In the process of the pole tilting or breaking, the corrugated tube provides sufficient deformation compensation space for the built-in cable, prevents the cable from breaking, and improves the structural reliability and impact buffer performance of the whole machine in the event of an emergency.

[0032] The detection and control module component 4 is integrated and installed inside the housing 1. The photoelectric module 40 is located at the front window position and is used to monitor foreign object information in the field of view. The antenna module 42 is responsible for wirelessly transmitting the collected data to the remote data center. The control module 43 is the core computing and data processing unit, which receives signals from the photoelectric module and the antenna module to realize intelligent identification and remote management. The power module 44 uses a high-performance battery or solar battery to provide the required energy and ensure the long-term stable operation of the equipment.

[0033] To enhance visual recognition and airport safety, the outer surface of the pole 2 is covered with a matte aluminum alloy base layer, which has anti-corrosion and anti-oxidation capabilities. The surface is coated with a red and white reflective paint layer, which complies with the warning specifications of airport navigation facilities and enhances visibility at night and in inclement weather.
