Description

Technical Field

[0001] This application relates to the technical field of airport lights, and particularly to an approach light. Background Art

[0002] With the continuous increase in air traffic volume, the growing airport throughput, and the control of airport operating costs, since multiple approach lights are installed on the airport runway, in order to facilitate the staff to control the approach lights, strict requirements are imposed on the installation and quality of the approach lights.

[0003] The control mechanism of the airport leads out a power line, and the power line is electrically connected to multiple approach lights on the airport waterway. The power line mainly supplies power to the approach lights, and the power line also has the function of transmitting a transmission signal to the approach lights. Currently, the approach lights only need to implement the function of turning on and off. When the power line is used for data signal transmission, it can reach 10b / s, which can meet the control of turning on and off the approach lights.

[0004] Regarding the above related technologies, with the continuous development of aerospace technology, it is necessary to control the approach lights to achieve more functions, such as editing programs, etc. The inventor believes that the above method of transmitting signals to the approach lights through the power line can only meet the control of turning on and off the approach lights, and there is a problem of slow data signal transmission, which cannot meet the multi-functional control of the approach lights and there is room for improvement. Summary of the Invention

[0005] In order to improve the signal transmission speed of the approach lights and meet the realization of more functions of the approach lights, this application provides an approach light.

[0006] An approach light provided by this application adopts the following technical solutions:

[0007] An approach light includes a cylinder body and a mounting shell fixed on the cylinder body, and further includes a light-emitting component arranged on the mounting shell to provide a light source for the airport;

[0008] A power supply component is arranged on the inner wall of the cylinder body to supply electrical energy to the light-emitting component;

[0009] A communication component is arranged on the inner wall of the cylinder body for receiving and transmitting wireless signals.

[0010] By adopting the above technical solutions, during the installation of the approach light, the cylinder body is buried under the airport runway in advance, the mounting shell is fixed on the opening of the cylinder body, the power supply component in the cylinder body is connected to the light-emitting component, the power supply component supplies power to the light-emitting component, and the light-emitting component emits light to the outside, playing a role in prompting the pilot; the communication component is a wireless communication module fixed on the inner wall of the cylinder body, and the communication component transmits signals from the inner wall of the cylinder body to the power supply component. By transmitting signals through the wireless module, it is no longer limited by the power line, improving the speed of data signals, thereby facilitating the approach light to implement more functions.

[0011] Optionally, a plurality of light-through holes are opened on the side wall of the mounting shell, and a blocking plate is fixed on each of the light-through holes, and the communication component is located near the light-through holes.

[0012] By adopting the above technical scheme, the opening of the light hole facilitates the staff to exchange information with the communication component inside the cylinder. The communication component can be a radio frequency transmitting and receiving device installed on the inner wall of the cylinder. The shape and position of the light hole are opened according to the needs of the radio frequency transmitting and receiving device. The material of the sealing plate can be glass, plastic, rubber and other materials. The sealing plate is fixed to the side wall of the mounting shell by glue. The sealing plate can transmit radio frequency signals. The setting of the sealing plate plays a role of sealing and waterproofing.

[0013] Optionally, one of the blocking plates blocks the light-through hole, a support rod is rotatably connected to the inner wall of the cylinder, the support rod is rotatably connected to the blocking plate, a connecting rod is fixed to the side wall of the support rod, a tensioning spring is provided on the inner wall of the cylinder, one end of the tensioning spring is fixed to the inner wall of the cylinder, and the other end is fixed to the outer wall of the connecting rod, and a driving member for driving the support rod to rotate is provided on the inner wall of the cylinder.

[0014] By adopting the above technical solution, when the navigation light needs to be repaired, the driving member drives the support rod to rotate, and the support rod drives the sealing plate to rotate, and the end of the sliding rod away from the sealing plate slides on the slide plate, and the tensioning spring rebounds, so that the sealing plate leaves the light-through hole, and the staff inspects the navigation light through the light-through hole; after the inspection is completed, the driving member drives the support rod to rotate toward the light-through hole, and the tensioning spring is stretched. Under the action of the tensioning spring's own rebound force, the sealing plate is driven to move toward the light-through hole, and the sliding rod slides to the top of the slide plate, and the sealing plate is blocked on the light-through hole under the support of the support rod and the sliding rod, thereby blocking the light-through hole.

[0015] Optionally, a roller is fixed to one end of the sliding rod away from the blocking plate, and the roller rolls on the sliding plate.

[0016] By adopting the above technical solution, the setting of the roller reduces the friction between the sliding rod and the sliding plate, so that the sliding of the sliding rod is smoother and the wear on the sliding rod is reduced.

[0017] Optionally, a buffer cavity is provided on the side of the cylinder facing away from the mounting shell, the cylinder is slidingly arranged with the buffer cavity, a support block is slidingly connected to the inner wall of the buffer cavity, a first buffer spring is provided on the side of the support block facing away from the cylinder, one end of the first buffer spring abuts against the inner wall of the buffer cavity, and the other end abuts against the side wall of the support block.

[0018] By adopting the above technical solution, before installing the navigation aid light, the buffer cavity is buried under the airport runway in advance, the cylinder body is supported on the support block, and the support block supports the cylinder body. When the aircraft tire rolls over the installation shell, the installation shell exerts a downward force on the cylinder body, and the cylinder body exerts a downward force on the support block, and the first buffer spring is compressed. When the aircraft passes over the installation shell, under the action of the self-return spring force of the first buffer spring, the installation shell slides back to the initial state, thereby reducing the damage to the installation shell.

[0019] Optionally, a fixing block is fixed on the inner wall of the buffer cavity, the support block is slidably connected to the fixing block, a support frame is slidably connected to the fixing block, and one end of the first buffer spring away from the support block abuts against the side wall of the support frame. The fixing block is hollow, a receiving rod is rotatably connected to the inner wall of the fixing block, a first sliding groove is formed on the side wall of the support block, a second sliding groove is formed on the side wall of the support frame, one end of the receiving rod is slidably connected to the first sliding groove, and the other end is slidably connected to the second sliding groove. A second buffer spring is fixed on the support frame, one end of the second buffer spring is fixed on the side wall of the support frame, and the other end is fixed on the inner wall of the fixing block.

[0020] By adopting the above technical solution, during the process of the support block moving downward, the receiving rod rotates and slides in the first sliding groove at the same time, and one end of the receiving rod away from the first sliding groove rotates and slides in the second sliding groove at the same time. The receiving rod exerts a force on the support frame in the direction towards the cylinder body, causing the support frame to slide on the fixing block, and both the first buffer spring and the second buffer spring are compressed, improving the stability of the buffer for the cylinder body.

[0021] Optionally, a guiding hole is formed in the fixing block, a guiding rod is fixed on the side wall of the support frame, the guiding rod is slidably connected to the guiding hole, a contact piece is fixed on the inner wall of the sliding groove, an electric contact block is fixed on the inner wall of the sliding groove, an avoidance groove is formed on the outer wall of the guiding rod, and the contact piece is slidably arranged with the avoidance groove; the driving member can be a servo motor. When the guiding rod slides in the direction away from the inner cavity of the guiding hole, the contact piece abuts against the electric contact block. When the contact piece abuts against the electric contact block, the power supply assembly supplies power to the servo motor, and a driving assembly for driving the guiding rod to move in the direction away from the inner cavity of the guiding hole is arranged on the installation shell.

[0022] By adopting the above technical solution, during the sliding process of the support frame, the guiding rod is driven to slide in the guiding hole. The arrangement of the guiding rod and the guiding hole guides the sliding of the support frame, making the sliding of the support frame smoother. When it is necessary to repair the navigation aid light, the driving component drives the guiding rod to move away from the inner cavity of the guiding hole. The guiding rod urges the contact piece to quickly contact the contact, and the power supply component supplies power to the driving piece, thereby controlling the rotation of the sealing plate. The contact piece is a spring piece. When the guiding rod slides into the inner cavity of the guiding hole, under the action of the resilience of the contact piece, the contact piece is separated from the contact block, thereby controlling the sealing of the light passing hole by the sealing plate.

[0023] Optionally, the driving component includes a towing rope fixed on the side wall of the support block and a pull ring fixed at the end of the towing rope away from the support block. A wire passing hole is formed on the side wall of the mounting shell, and the towing rope passes through the wire passing hole. The pull ring abuts against the outer wall of the mounting shell.

[0024] By adopting the above technical solution, the staff pulls the pull ring, and drives the support block to slide under the traction of the towing rope, thereby driving the support frame to slide.

[0025] Optionally, a clamping groove is formed on the side wall of the mounting shell, and the pull ring is clamped in the clamping groove.

[0026] By adopting the above technical solution, the formation of the clamping groove facilitates the clamping of the pull ring. Under the action of the first buffer spring and the second buffer spring, the towing rope is in a tensioned state. The pull ring is clamped in the clamping groove, reducing the damage caused by the aircraft tire to the pull ring.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The power supply component provides an electrical signal to the light-emitting component, and the communication component is provided to facilitate the staff to obtain signals. When installing the navigation aid light, the cylinder body is buried under the airport runway, and the mounting shell is fixed on the cylinder body, thereby realizing the installation of the navigation aid light. The power supply component is arranged on the inner wall of the cylinder body, and the power supply component supplies power to the light-emitting component, omitting the link of connecting the communication wire to the airport control system, thereby reducing the consumption of labor.

[0029] 2. When it is necessary to repair the navigation aid light, pull the pull ring. Under the traction of the towing rope, the support frame slides. The support frame drives the guiding rod to slide away from the inner cavity of the guiding hole. Under the abutment of the inner wall of the avoidance groove, the contact piece abuts against the contact block, thereby connecting the power supply component and the driving piece. Under the drive of the driving piece, the light passing hole of the navigation aid light is opened, facilitating the staff to repair the navigation aid light. BRIEF DESCRIPTION OF THE DRAWINGS

A light-emitting component 3 is arranged on the outer wall of the mounting shell 2. In this application, the light-emitting component 3 includes a mounting block 31 integrally fixed to the outer wall of the mounting shell 2 and a light-emitting lamp 32 mounted on the mounting block 31. The mounting block 31 is inclined, so that the light-emitting lamp 32 emits light inclined to the airport runway, facilitating pilots to identify the runway.

[0043] Refer to Figure 1 and Figure 2 , A power supply component 4 is arranged on the inner wall of the cylinder body 1. The power supply component 4 supplies power to the light-emitting lamp 32. A fixing plate 15 is welded and fixed on the inner wall of the cylinder body 1. The power supply component 4 includes a battery pack 41 fixed to the fixing plate 15 by bolts and a circuit board 42 fixed to the inner wall of the cylinder body 1 by screws. The battery pack 41 is electrically connected to the circuit board 42, and the circuit board 42 is electrically connected to the light-emitting lamp 32. The battery pack 41 supplies power to the circuit board 42, and the circuit board 42 supplies power to the light-emitting lamp 32, so that the light-emitting lamp 32 emits light.

[0044] Refer to Figure 1 and Figure 2 , A communication component 5 is arranged on the inner wall of the cylinder body 1. The communication component 5 emits radio frequency signals to the outside; a plurality of light-transmitting holes 11 are penetrated through the side wall of the mounting shell 2. In this application, four light-transmitting holes 11 are provided. Sealing plates 111 are adhesively fixed to the inner walls of the four light-transmitting holes 11 by glue. In this application, the sealing plates 111 are made of materials such as glass, plastic, and rubber that can transmit radio frequency signals, so as to achieve the functions of sealing and waterproofing. Workers emit signals into the inner cavity of the cylinder body 1 through the light-transmitting holes 11 and receive the signals emitted by the communication component 5. Signals are transmitted wirelessly, no longer limited by power lines, improving the speed of data signals, which can reach 1000K / S, thus facilitating the control of the approach light to realize more functions.

[0045] In the first embodiment of this application, the implementation principle of an approach light is as follows: When installing the approach light, the cylinder body 1 is buried underground under the airport waterway in advance, and the mounting shell 2 is fixed to the opening of the cylinder body 1 by bolts. Signals in the cylinder body 1 are received through the sealing plate 111, so as to facilitate the control of the on / off of the light-emitting lamp 32.

[0046] Embodiment Two

[0047] The difference between Embodiment Two and Embodiment One is: Refer to Figure 3 , Figure 4 and Figure 5, one of the plugging plates 111 plugs the corresponding light-passing hole 11, and the other plugging plates 111 are adhesively bonded to the mounting shell 2 with glue. A bracket 16 is fixed to the inner wall of the cylinder body 1 by bolts. A rotating shaft 161 is rotatably connected to the bracket 16. A support rod 12 is welded and fixed to the outer wall of the rotating shaft 161. One end of the support rod 12 away from the rotating shaft 161 is rotatably connected to the side wall of the plugging plate 111 plugging the light-passing hole 11. One end of the support rod 12 close to the rotating shaft 161 is welded and fixed with a connecting rod 121. One end of the connecting rod 121 away from the support rod 12 is welded and fixed with a first fixing column 1211. A second fixing column 17 is welded and fixed to the inner wall of the cylinder body 1. A tension spring 13 is arranged between the first fixing column 1211 and the second fixing column 17. One end of the tension spring 13 is hooked on the first fixing column 1211, and the other end is hooked and fixed on the second fixing column 17. A driving member 6 for driving the rotating shaft 161 to rotate is arranged on the inner wall of the cylinder body 1.

[0048] Referring to Figure 4 and Figure 5 , a sliding plate 14 is welded and fixed to the inner wall of the cylinder body 1. The sliding plate 14 is inclined in the direction towards the light-passing hole 11. A sliding rod 112 is fixed to the side wall of the plugging plate 111 connected to the support rod 12 by bolts. A roller 1121 is installed at one end of the sliding rod 112 away from the plugging plate 111. The roller 1121 rolls on the sliding plate 14. In this application, the driving member 6 can be a servo motor. The driving member 6 drives the rotating shaft 161 to rotate. The rotating shaft 161 drives the support rod 12 to rotate. The support rod 12 drives the plugging plate 111 to rotate. The tension spring 13 is stretched. Under the action of the rotation of the support rod 12 and the self-return elastic force of the tension spring 13, the roller 1121 rolls on the sliding plate 14. After the plugging plate 111 plugs the light-passing hole 11, under the action of the self-return elastic force of the tension spring 13, the plugging plate 111 abuts against the side wall of the mounting shell 2, thereby improving the sealing performance of the navigation light.

[0049] Referring to Figure 6 , a buffer cavity 7 is slidably connected to the side of the cylinder body 1 away from the mounting shell 2. A fixing block 73 is clamped and fixed to the inner wall of the buffer cavity 7. The fixing block 73 is hollow. A support block 71 is slidably connected to the fixing block 73. A support frame 731 is slidably connected to the inner wall of the fixing block 73. A first buffer spring 72 is installed between the support block 71 and the support frame 731. One end of the first buffer spring 72 abuts against the side of the support block 71 facing the support frame 731, and the other end abuts against the side of the support frame 731 facing the support block 71. The side of the cylinder body 1 away from the mounting shell 2 abuts against the side of the support block 71 away from the support frame 731. When the aircraft tire passes over the mounting shell 2, the cylinder body 1 slides downward, and the first buffer spring 72 is compressed. The setting of the first buffer spring 72 plays a buffering role, thereby reducing the damage to the navigation light.

[0050] Referring toFigure 6 On the side wall of the support block 71, a first sliding groove 711 is provided. In this application, two first sliding grooves 711 are provided; on the side wall of the support frame 731, a second sliding groove 7311 is provided. In this application, two second sliding grooves 7311 are provided. On the inner wall of the fixed block 73, two mounting shafts 734 are welded and fixed. On the outer walls of the mounting shafts 734, receiving rods 732 are rotatably connected. One end of one receiving rod 732 is rotatably connected to the inner wall of the first sliding groove 711, and the other end is rotatably connected to the inner wall of the second sliding groove 7311; one end of the other receiving rod 732 is rotatably connected to the inner wall of the corresponding first sliding groove 711, and the other end is rotatably connected to the inner wall of the second sliding groove 7311. When the support block 71 slides on the fixed block 73, the receiving rod 732 has a tendency to slide while rotating in the first sliding groove 711 and the second sliding groove 7311.

[0051] Refer to Figure 6 Between the inner wall of the support frame 731 and the inner wall of the fixed block 73, a second buffer spring 74 is installed. One end of the second buffer spring 74 abuts against the side wall of the support frame 731, and the other end abuts against the inner wall of the fixed block 73. The support block 71 slides towards the support frame 731, causing the receiving rod 732 to rotate. The receiving rod 732 drives the support frame 731 to move towards the cylinder 1. The second buffer spring 74 is compressed. Under the action of the self-return force of the second buffer spring 74, the support frame 731 has a tendency to move in the direction away from the mounting shell 2, making the buffering effect of the navigation light more obvious, thereby better protecting the navigation light.

[0052] Refer to Figure 6 On the inner wall of the fixed block 73, a guiding hole 733 is provided. In this application, two guiding holes 733 are provided. On the side wall of the support frame 731, two guiding rods 7312 are welded and fixed. The guiding rods 7312 and the guiding holes 733 are arranged in one-to-one correspondence. The guiding rods 7312 are slidably connected in the guiding holes 733. The arrangement of the guiding rods 7312 and the guiding holes 733 guides the sliding of the support frame 731, making the sliding of the support frame 731 more stable.

[0053] Refer to Figure 4 and Figure 7, a driving assembly 8 for driving the guide rod 7312 to move away from the inner cavity of the guide hole 733 is provided on the installation shell 2. A contact piece 7331 is riveted and fixed on the inner wall of the guide hole 733. In this application, the contact piece 7331 is a spring piece. An avoidance groove 7313 is formed on the outer wall of the guide rod 7312. The contact piece 7331 is located in the avoidance groove 7313. The contact piece 7331 is arranged at an angle with the inner wall of the guide hole 733. The opening of the angle formed by the contact piece 7331 and the inner wall of the guide hole 733 faces the support frame 731. A contact block 7332 is welded and fixed on the inner wall of the guide hole 733. The driving assembly 8 drives the guide rod 7312 to move away from the inner cavity of the guide hole 733, pressing the contact piece 7331 against the contact block 7332. The contact block 7332 is electrically connected to the power supply assembly 4. When the contact piece 7331 abuts against the trigger block, the power supply assembly 4 is connected to the driving member 6 to control the operation of the driving member 6.

[0054] Refer to Figure 8 , a threading hole 21 is formed through the side wall of the installation shell 2. The driving assembly 8 includes a traction rope 81 with one end fixed on the side wall of the support block 71. The end of the traction rope 81 away from the support block 71 passes through the threading hole 21; the driving assembly 8 further includes a pull ring 82 fixed at the end of the traction rope 81 away from the support block 71. The staff pulls the pull ring 82, and the pull ring 82 pulls the traction rope 81 to move, thereby driving the support block 71 to move.

[0055] Refer to Figure 4 , Figure 6 and Figure 8 , a clamping groove 22 is formed on the outer wall of the installation shell 2. The shape of the clamping groove 22 is the same as that of the pull ring 82. When the staff needs to repair the navigation light, they pull the pull ring 82, and the driving member 6 drives the support rod 12 to rotate, and the blocking plate 111 rotates away from the light passing hole 11, which is convenient for the staff to repair the navigation light. After the repair is completed, under the action of the self-return spring force of the first buffer spring 72 and the second buffer spring 74, the pull ring 82 abuts against the outer wall of the installation shell 2. At this time, the staff snaps the pull ring 82 into the clamping groove 22 to prevent the pull ring 82 from being crushed when the aircraft tire rolls over the installation shell 2.

[0056] In the second embodiment of the present application, the implementation principle of an aid navigation light is as follows: When installing the aid navigation light, the buffer cavity 7 is buried under the airport waterway in advance, and then the cylinder body 1 is installed on the side of the support block 71 away from the fixed block 73. The installation shell 2 is fixed to the opening of the cylinder body 1 by bolts. The communication component 5 on the inner wall of the cylinder body 1 sends radio frequency signals to the outside through the sealing plate 111. The staff controls the current conduction between the signal power supply component 4 and the light-emitting lamp 32 by emitting signals into the cylinder body 1, so as to control the light-emitting component 3 to emit light. When it is necessary to repair the aid navigation light, the staff pulls the pull ring 82, the pull ring 82 drives the traction rope 81, and the traction rope 81 pulls the support block 71 to slide. Under the action of the connecting rod 732, the support frame 731 moves away from the installation shell 2, so that the contact piece 7331 contacts the contact block 7332, realizing the electrical connection of the power supply component 4 and the driving member 6, thereby controlling the opening of the sealing plate 111. The staff can repair the aid navigation light through the light passing hole 11.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
