Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, specifically a secondary piping structure applied to a navigation aid system. Background Technology

[0002] Airport lights, like airport ground markings, are visual navigation aids. Their purpose is to better guide aircraft to safe approach and landing, especially during nighttime flights and flights in low cloud and low visibility conditions. Airport lighting systems play an irreplaceable role in these situations. The airport navigation light system consists of proximity lights, runway lights, and taxiway lights, each with different functions and roles. Glide slope lights, a type of proximity light, are located at each end of the runway and play a crucial role in aircraft takeoff and landing, serving as guidance markers for aircraft landing. Without navigation lights, nighttime flights would be impossible to guarantee, posing a significant threat to aviation safety and necessitating the closure of the airport. Therefore, the stable operation of navigation lights is directly related to the safety of aircraft takeoff and landing.

[0003] When laying cables for navigation lights or FOD monitoring equipment, airports typically lay a conduit system first, and then pass the cables through the conduit system after construction is completed. The pre-laid conduit system protects the cables, prevents damage, and facilitates secondary cable replacement.

[0004] Existing navigation light conduits typically feature three-core cables for grounding, connecting to the positive power supply, and controlling the lights. However, existing cable protection conduits lack the ability to individually protect each cable, resulting in the three cables becoming tangled and intertwined. If one cable fails and leaks electricity, it can easily affect the normal operation of the other two, and targeted repairs are inconvenient. Therefore, it is necessary to propose a secondary piping structure for navigation systems to address the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a secondary piping structure for navigation aid systems, which has the advantages of being able to protect pipes separately, thus solving the problem that existing pipes do not have the ability to protect cables separately.

[0006] To achieve the above-mentioned purpose of protecting the pipe fittings separately, this utility model provides the following technical solution: a secondary piping structure for a navigation aid system, including a corrugated pipe, a connecting pipe fitting sleeved on the outside of the corrugated pipe, a threaded end of the connecting pipe fitting, a first sealing ring on the outside of the threaded end, an inner sealing ring inside the connecting pipe fitting, a wire passage opening inside the inner sealing ring, an external device connected to the other end of the threaded end, a protective component inside the corrugated pipe, and a sealing cap on the front of the corrugated pipe;

[0007] The protective component includes a protective ring, which is inserted into the inside of the corrugated pipe. A protective cylinder is movably installed inside the protective ring. A limiting groove is formed on the outside of the protective cylinder. A cable is installed inside the limiting groove. A limiting protrusion is provided on the side of the protective cylinder. A protective plate is fixedly connected to one side of the limiting protrusion.

[0008] Furthermore, a through groove is provided on the inner wall of the limiting groove, a protective plate is slidably installed inside the through groove, and a knob is movably installed on the front of the protective cylinder.

[0009] Furthermore, the protective ring is semi-open, and a cable is installed inside the limiting groove.

[0010] Furthermore, a through hole is provided on the front side of the sealing cover, and a second sealing ring is provided inside the through hole.

[0011] Furthermore, both the corrugated pipe and the sealing cap are provided with external threads on the outside, and the connecting pipe is provided with internal threads on the inside. Both the corrugated pipe and the sealing cap are connected to the connecting pipe, and the inner sealing ring has a barrel-shaped structure.

[0012] Furthermore, there are three sets of wire passages, through holes, and limiting grooves, and the three sets of wire passages, through holes, and limiting grooves correspond to each other. A strip groove is opened on the inner wall of the corrugated pipe, and a strip block is provided on the outside of the protective ring.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This secondary piping structure, applied to the navigation aid system, incorporates a first sealing ring, a second sealing ring, and an inner sealing ring. This creates a complete protective conduit for the corrugated pipe, connecting fittings, protective ring, and threaded joints, forming a well-sealed piping system. The corrugated surface of the pipe ensures rigidity while maintaining flexibility, allowing it to bend with the terrain and facilitating insertion into the connecting fittings. External equipment connects to the threaded joints, and the first sealing ring provides waterproofing. Cables are then passed through the cable guides on the corrugated pipe and the inner sealing ring to connect to the external equipment. During cable insertion, the smooth inner wall of the corrugated pipe and low coefficient of friction make the process easy and convenient. The inner sealing ring effectively provides waterproofing, insect protection, and dust protection, ensuring the stable operation of the navigation light.

[0015] This secondary piping structure applied to the navigation aid system, through the inclusion of protective components, allows the navigation light to be connected by three cables during use. By placing the cables in the through slots and moving the limiting protrusions, the limiting protrusions further push the protective plate towards the top of the cables, thereby limiting the cables and preventing them from falling out of the through slots and protective rings, thus affecting the protection effect on the cables. The setting of multiple through slots can provide separate protection for the three cables of the navigation light, avoiding leakage from a single cable that could cause damage to other cables and increase maintenance costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A secondary piping structure for a navigation aid system in this embodiment includes a corrugated pipe 1, a connecting fitting 2 sleeved on the outside of the corrugated pipe 1, a threaded end 3 at one end of the connecting fitting 2, a first sealing ring 4 on the outside of the threaded end 3, an inner sealing ring 13 inside the connecting fitting 2, a wire-passing port 14 inside the inner sealing ring 13, an external device 15 connected to the other end of the threaded end 3, a protective component 12 inside the corrugated pipe 1, and a sealing cap 6 on the front of the corrugated pipe 1.

[0023] The protective component 12 includes a protective ring 5. The protective ring 5 is inserted into the inside of the corrugated pipe 1. A protective cylinder 16 is movably installed inside the protective ring 5. A limiting groove 121 is opened on the outside of the protective cylinder 16. A cable 122 is arranged inside the limiting groove 121. A limiting protrusion 123 is provided on the side of the protective cylinder 16. A protective plate 124 is fixedly connected to one side of the limiting protrusion 123.

[0024] In the implementation of the case, by setting the first sealing ring 4, the second sealing ring 8 and the inner sealing ring 13, the corrugated pipe 1, the connecting fitting 2, the protective ring 5 and the threaded joint 3 are in a complete protective pipeline, so that the corrugated pipe 1, the connecting fitting 2, the protective ring 5 and the threaded joint 3 form a pipeline system with relatively good sealing performance.

[0025] In the implementation of the case, the corrugated pipe 1 has a corrugated surface, which ensures rigidity while having a certain degree of flexibility, and can be bent according to the terrain. It is convenient to insert the corrugated pipe 1 into the interior of the connecting pipe 2. The external device 15 is connected to the threaded joint 3 and is waterproofed by the first sealing ring 4. Then, the cable 122 is passed through the cable passage 14 on the corrugated pipe 1 and the inner sealing ring 13 to connect with the external device 15. During the cable threading process, the inner wall of the corrugated pipe 1 is smooth and has a low coefficient of friction, which makes the cable threading easy and convenient. The inner sealing ring 13 can effectively play the role of waterproofing, insect prevention, and dust prevention, ensuring the stable operation of the navigation light.

[0026] In the implementation of the case, the navigation light is connected by three cables 122. By placing the cables 122 in the through groove 125 and moving the limiting protrusion 123, the limiting protrusion 123 further pushes the protective plate 124 towards the top of the cables 122, thereby limiting the cables 122 and preventing them from falling out of the through groove 125 and the protective ring 5, which would affect the protection effect of the cables 122. The setting of multiple through grooves 125 can provide separate protection for the three cables 122 of the navigation light, avoiding leakage of a single cable 122 that could cause other damage and increase maintenance costs.

[0027] In the implementation of the case, by setting the strip block 11, the protective cylinder 16 is inserted into the strip groove 9 through the strip block 121, thereby realizing the insertion of the protective cylinder 16 into the corrugated pipe 1. By rotating the knob 126, the protective cylinder 16 is rotated, which makes it convenient to place the cables 122 with different functions inside the limiting groove 121.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, place the three cables 122 into the limiting grooves 121 respectively, and limit the cables 122 by the protective plate 124;

[0030] 2) Then the protective cylinder 16 is inserted into the corrugated pipe 1 of the strip groove 9 through the strip block 121;

[0031] 3) Then screw the corrugated pipe 1 into the connecting pipe fitting 2 and fix the sealing cap 6 to the side of the connecting pipe fitting 2;

[0032] 4) Finally, connect the external device 15 to the threaded joint 3 to form a complete piping system.

[0033] In summary, this secondary piping structure applied to the navigation aid system, by setting a first sealing ring 4, a second sealing ring 8, and an inner sealing ring 13, makes the corrugated pipe 1, connecting fitting 2, protective ring 5, and threaded joint 3 a complete protective pipeline. This allows the corrugated pipe 1, connecting fitting 2, protective ring 5, and threaded joint 3 to form a pipeline system with good sealing performance. The corrugated surface of the corrugated pipe 1 ensures rigidity while providing a certain degree of flexibility, allowing it to bend according to the terrain. This facilitates the insertion of the corrugated pipe 1 into the connecting fitting 2. The external device 15 is connected to the threaded joint 3, and the first sealing ring 4 provides waterproofing. Subsequently, the cable 122 is passed through the cable passage 14 on the corrugated pipe 1 and the inner sealing ring 13 to connect to the external device 15. During the cable threading process, the smooth inner wall of the corrugated pipe 1 and the low coefficient of friction make the threading easy and convenient. The inner sealing ring 13 effectively provides waterproofing, insect prevention, and dust prevention, ensuring the stable operation of the navigation light.

[0034] Furthermore, by setting up the protective component 12, during use, the navigation light is connected by three cables 122. By placing the cables 122 in the through groove 125 and moving the limiting protrusion 123, the limiting protrusion 123 further pushes the protective plate 124 towards the top of the cables 122, thereby limiting the cables 122 and preventing them from falling out of the through groove 125 and the protective ring 5, which would affect the protection effect of the cables 122. The setting of multiple through grooves 125 can provide separate protection for the three cables 122 of the navigation light, avoiding leakage of a single cable 122 that could cause other damage and increase maintenance costs.
