Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of adjustable lamps, and specifically to a lamp structure applicable to an adjustable bracket for a runway. Background Art
[0002] Airport runway lights are important ground lighting devices to ensure the safe takeoff and landing of aircraft. Airport runway lights worldwide have consistency and universality. No matter which airport a pilot takes off or lands at, they can identify relevant information about the runway through the same lighting signals, thus ensuring flight safety.
[0003] Currently, when the temperature drops rapidly at night and the temperature of the runway lights themselves is relatively high, water vapor in the surrounding air will condense on the surface of the lamps when it meets cold. For example, in the early morning of autumn and winter, the temperature difference between day and night is large, and the ground heat dissipates rapidly, and fog may appear around the runway lights. Or in the rainy season, there are a large number of small water droplets suspended in the air, which are also likely to adhere to the surface of the runway lights to form fog. This will seriously affect the penetrability of the runway light, unable to help the pilot more accurately judge the position and direction of the runway, and reduce flight safety. Therefore, we propose a lamp structure applicable to an adjustable bracket for a runway. Summary of the Invention
[0004] In view of the problems in the related art, the present invention proposes a lamp structure applicable to an adjustable bracket for a runway to overcome the above-mentioned technical problems existing in the prior related art.
[0005] The present invention provides the following technical solution: A lamp structure applicable to an adjustable bracket for a runway, including a support base, a push rod, and a pulling grip. A fixed column is fixedly provided at the top of the support base. An inner wall of the fixed column is sleeved with a connecting rod. A spring is fixedly provided at the bottom of the connecting rod. Three connecting components are fixedly provided at the bottom of the connecting rod on one side close to the spring. The inner wall of the fixed column is slidably connected with the three connecting components through a limited position groove opened. On one side corresponding to the limited position groove at the top of the inner wall of the fixed column, three first ventilation holes are opened. Communicating columns corresponding to their positions are fixedly provided at the side walls of the three first ventilation holes. A rotating shaft is fixedly connected between two adjacent communicating columns. The rotating shaft penetrates through a refraction plate and is rotatably connected with the refraction plate; A blowing port is fixedly provided at the top of the communicating column. Three scraping plates are fixedly provided at the side wall of the blowing port. A communicating pipe penetrates through the side wall of the communicating column. The side wall of the communicating column is inserted and connected with an air inlet hole through the communicating pipe. An airbag is fixedly provided at the bottom of the air inlet hole. A connecting platform is sleeved on the outer wall of the airbag. A lamp is fixedly provided on the inner wall of the connecting platform.
[0006] Preferably, the three connecting components include extension blocks located at the bottom of the side wall of the connecting rod. Second ventilation holes are formed on the surface of the extension blocks. The size of the second ventilation holes matches the size of the first ventilation holes. Sliders are slidably arranged on both sides of the outer wall of the extension blocks. A baffle is horizontally arranged through the inner wall of the extension block on the side wall of the slider.
[0007] Preferably, an activity cavity is provided at the inner wall of the fixed column near the bottom of the limiting groove, and the size of the activity cavity is adapted to the size of the fixed disk connected to the bottom of the spring.
[0008] Preferably, the three scraping plates are distributed in a circumferential array on the side wall of the air blowing port, and the side wall of the scraping plate is in contact with the lamp.
[0009] Preferably, a limiting block is fixedly arranged at the top of the limiting groove, and the position of the limiting block corresponds to the position of the slider.
[0010] Preferably, an air pump is fixedly arranged in the inner wall of the connecting rod. An air ventilation groove is provided at the bottom of the air pump, and the position of the air ventilation groove corresponds to the position of the second ventilation hole.
[0011] Preferably, the refraction plates are distributed in a circumferential array on the side wall of the communication column, and the surface of the refraction plate is provided with a multi-prism.
[0012] Preferably, a magnetic attraction ring is sleeved on the outer wall of the connecting platform, and the material of the magnetic attraction ring is a magnetic attraction plate.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. For the lamp structure applicable to the runway adjustable bracket, a part of the gas in the communication column is blown towards the surface of the lamp through the air blowing port. After applying the defogging agent, the air blowing port continuously blows air towards the outer wall of the lamp. On the one hand, it further improves the defogging efficiency of the defogging agent, avoiding phenomena such as the reduction of the defogging agent efficiency caused by weather reasons. On the other hand, it effectively reduces the temperature difference between the inside of the lamp and the external environment, and at the same time avoids the phenomenon of water droplets hanging on the wall caused by too large a temperature difference, reducing the reduction of the refraction efficiency and scattering effect of the lamp.
[0014] 2. For the lamp structure applicable to the runway adjustable bracket, the communication column inflates the air bag through the communication pipe, so that the air bag expands after being filled with gas, effectively fixing the stability of the lamp placed in the connecting platform. Since the lamp is prone to shaking in strong wind weather, it reduces the collision generated when the lamp shakes on the inner wall of the connecting platform, avoiding damage to the surface.
[0015] 3. The lamp structure applicable to the runway adjustable bracket, since the refraction plate is set as a multi - prism, the multi - prism can refract the light of the runway lamp in multiple directions, making the light scatter in a larger range. Pilots can more clearly see the indication of the runway lamp at different angles and positions. Especially under low visibility conditions, such as foggy days, rainy days or at night, this dynamic multi - angle refraction can effectively improve the light penetration and visible distance, helping pilots more accurately judge the position and direction of the runway. At the same time, it makes the light intensity distribution around the runway lamp more uniform, avoiding the uneven brightness situation that may occur in traditional lamps.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figure 1-7, A lamp structure applicable to a runway adjustable bracket, including a support base 1, a push rod 2 and a pulling grip 14. A fixed column 3 is fixedly provided at the top end of the support base 1. An inner wall of the fixed column 3 is sleeved with a connecting rod 4. A spring 13 is fixedly provided at the bottom of the connecting rod 4. At the bottom end of the connecting rod 4, three connecting components are fixed on one side close to the spring 13. The inner wall of the fixed column 3 is slidably connected to the three connecting components through a provided limiting groove 10. At one side corresponding to the limiting groove 10 at the top end of the inner wall of the fixed column 3, three first air vents 12 are opened. At the side walls of the three first air vents 12, communicating columns 8 corresponding to their positions are fixedly provided. A rotating shaft 24 is fixedly connected between two adjacent communicating columns 8. The rotating shaft 24 penetrates through a refraction plate 19 and is rotatably connected to the refraction plate 19; At the top end of the communicating column 8, a blowing port 9 is fixedly provided. Three scraping plates 18 are fixedly provided at the side wall of the blowing port 9. A communicating pipe 21 penetrates through the side wall of the communicating column 8. The side wall of the communicating column 8 is inserted and connected to an air inlet hole 22 through the communicating pipe 21. An airbag 23 is fixedly provided at the bottom of the air inlet hole 22. A connecting platform 5 is sleeved on the outer wall of the airbag 23. A lamp 7 is fixedly provided on the inner wall of the connecting platform 5.
[0020] It should be noted that when the lamp 7 needs to be replaced, the grip 14 can be pulled downward manually. Since three extension blocks 15 are fixedly provided at the bottom of the side wall of the connecting rod 4, and the size of the extension blocks 15 is adapted to the size of the limiting groove 10 opened on the inner wall of the connecting rod 4.
[0021] In an alternative embodiment: The three connecting components include extension blocks 15 located at the bottom of the side wall of the connecting rod 4. Second air vents 16 are opened on the surface of the extension blocks 15. The size of the second air vents 16 matches the size of the first air vents 12. Sliders 17 are slidably provided on both sides of the outer wall of the extension blocks 15. A baffle is horizontally arranged through the inner wall of the extension blocks 15 on the side walls of the sliders 17.
[0022] It should be noted that when the extension block 15 moves to the top end of the limiting groove 10, the second air vents 16 and the position of the extension block 15 are communicated. The limiting block 11 pushes the slider 17 to move downward, opening the originally blocked second air vents 16. At this time, the gas in the air pump 20 is blown towards the communicating column 8 through the extension block 15. A part of the gas in the communicating column 8 is blown towards the surface of the lamp 7 through the blowing port 9. After applying the defogging agent, the blowing port 9 continuously blows air towards the outer wall of the lamp 7, which on the one hand further improves the defogging efficiency of the defogging agent and avoids phenomena such as the reduction of the defogging agent efficiency caused by weather reasons.
[0023] In an alternative embodiment: An activity cavity is provided at the bottom end of the inner wall of the fixed column 3 close to the limiting groove 10, and the size of the activity cavity is adapted to the size of the fixed disk connected to the bottom of the spring 13.
[0024] It should be noted that when the extension block 15 slides downward along the track of the limit groove 10 into the circular movable cavity on the inner wall of the connecting rod 4 and rotates to a certain position, the three extension blocks 15 are rotated to be separated from the track limited by the limit groove 10, the surface of the extension block 15 fits against the top of the movable cavity, and the spring is compressed by the thrust force in the movable cavity.
[0025] In an alternative embodiment: the three scraping plates 18 are distributed in a circumferential array on the side wall of the air blowing port 9, and the side wall of the scraping plate 18 is in contact with the lamp 7.
[0026] It should be noted that when the lamp 7 moves downward, the inclined side wall of the scraping plate 18 scrapes off impurities such as mosquitoes and dust attached to the outer wall of the lamp 7, which slide down to the ground, realizing the cleaning of the lamp cavity before maintenance, preventing sundries and pollutants from adhering to the side wall of the ground lamp and causing inconvenience to the maintenance process. In addition, cleaning the lamp cavity before maintenance effectively slows down the aging speed of the equipment. At the same time, these obstacles will weaken the transmission and scattering effects of the light. By scraping and cleaning, these obstacles can be completely removed, enabling the light to shine out fully and clearly, thereby improving the overall illumination brightness and uniformity of the runway lights and providing clearer runway guidance for pilots.
[0027] In an alternative embodiment: a limit block 11 is fixedly provided at the top of the limit groove 10, and the position of the limit block 11 corresponds to the position of the slider 17.
[0028] It should be noted that since the limit block 11 is fixedly provided at the top end of the limit groove 10, when the extension block 15 moves to the top end of the limit groove 10, the positions of the second ventilation hole 16 and the extension block 15 are connected, and the limit block 11 pushes the slider 17 downward to open the originally blocked second ventilation hole 16. At this time, the gas in the air pump 20 can be blown towards the connecting column 8 through the extension block 15.
[0029] In an alternative embodiment: an air pump 20 is fixedly provided on the inner wall of the connecting rod 4, and a ventilation groove is provided at the bottom of the air pump 20, and the position of the ventilation groove corresponds to the position of the second ventilation hole 16.
[0030] It should be noted that the gas in the air pump 20 is blown towards the connecting column 8 through the extension block 15, avoiding phenomena such as reduced efficiency of the defogging agent caused by weather reasons. On the other hand, it effectively reduces the temperature difference between the inside of the lamp 7 and the external environment, and at the same time avoids the phenomenon of water droplets hanging on the wall caused by too large a temperature difference, reducing the reduction of the refraction efficiency and scattering effect of the lamp 7.
[0031] In an alternative embodiment: the refraction plates 19 are distributed in a circumferential array on the side wall of the connecting column 8, and the surface of the refraction plate 19 is provided with a multi-prism.
[0032] It should be noted that since the refraction plate 19 is a multi-prism, the multi-prism can refract the light of the runway lights in multiple directions, causing the light to scatter over a larger range. Pilots can see the runway light indications more clearly at different angles and positions. Especially under low visibility conditions such as fog, rain or at night, this dynamic multi-angle refraction can effectively improve the light penetration and visible distance, helping pilots more accurately judge the position and direction of the runway. At the same time, it makes the light intensity distribution around the runway lights more uniform, avoiding the uneven brightness that may occur in traditional lamps.
[0033] In an optional embodiment: A magnetic attraction ring 6 is sleeved on the outer wall of the connecting platform 5, and the material of the magnetic attraction ring 6 is a magnetic attraction plate.
[0034] It should be noted that a magnetic attraction ring 6 is sleeved on the outer wall of the connecting platform 5. The magnetic attraction ring 6 is a magnetic attraction plate, magnetically connecting the inner wall of the communicating column 8 with the magnetic attraction ring 6, effectively enhancing the stability of the device.
[0035] Working principle: When the lamp 7 needs to be replaced, the pulling grip 14 can be manually pulled downward. Since three extension blocks 15 are fixedly provided at the bottom of the side wall of the connecting rod 4, and the size of the extension blocks 15 is adapted to the size of the limiting groove 10 provided at the inner wall of the connecting rod 4. When the extension blocks 15 slide downward along the track of the limiting groove 10 into the circular activity cavity at the inner wall of the connecting rod 4 and rotate to a certain position, the three extension blocks 15 are rotated to be separated from the track limited by the limiting groove 10, and the surface of the extension blocks 15 fits against the top of the activity cavity. The spring is squeezed by the thrust in the activity cavity. At this time, the connecting rod 4 is sleeved on the inner wall of the fixed column 3, and the connecting platform 5 and the lamp 7 move downward along with the descent of the connecting rod 4. The air blowing port 9 is connected to the side wall of the fixed column 3 through the communicating column 8 provided at the bottom. At this time, the scraping plates 18 are arranged in a circumferential array on the side wall of the air blowing port 9. When the lamp 7 moves downward, the inclined side walls of the scraping plates 18 are used to scrape off impurities such as mosquitoes and dust attached to the outer wall of the lamp 7, which slide to the ground, realizing the cleaning of the lamp cavity before maintenance, preventing sundries and pollutants from adhering to the side wall of the ground lamp, causing inconvenience to the maintenance process. In addition, cleaning the lamp cavity before maintenance effectively slows down the aging speed of the device. At the same time, these obstacles will weaken the transmission and scattering effects of the light. By scraping and cleaning, these obstacles can be completely removed, allowing the light to shine out fully and clearly, thereby improving the overall illumination brightness and uniformity of the runway lights and providing clearer runway guidance for pilots. After the detection is completed, rotate the connecting rod 4 until the position of the extension block 15 corresponds to that of the limit groove 10. Since the limit block 11 is fixedly arranged at the top of the limit groove 10, when the extension block 15 moves to the top of the limit groove 10, the second ventilation hole 16 and the extension block 15 are in communication. The limit block 11 pushes the slider 17 downward to open the originally blocked second ventilation hole 16. At this time, the gas in the air pump 20 is blown towards the connecting column 8 through the extension block 15. When the spring 13 drives the lamp 7 to move upward and passes by the scraper 18 again, the scraper 18 evenly coats the outer wall of the lamp 7 with the defogging mixture. Since airports often have fog, moisture and other conditions due to weather reasons, which will seriously affect the penetration of runway lights, the antifogging agent can form a transparent and antifogging film on the surface of the lamp, reducing the scattering and refraction of light, enabling the light to penetrate the fog more effectively, improving the pilot's recognition of runway lights under low visibility conditions, and ensuring flight safety; When the connecting platform 5 rises to the top of the connecting column 8, since the magnetic attraction ring 6 is sleeved on the outer wall of the connecting platform 5 and the magnetic attraction ring 6 is a magnetic attraction plate, the inner wall of the connecting column 8 is magnetically connected to the magnetic attraction ring 6, effectively enhancing the stability of the device. When the connecting platform 5 stops rising, since the airbag 23 is arranged in the connecting platform 5, at this time, the connecting pipe 21 connected to the bottom of the connecting column 8 is inserted into the air inlet hole 22 at the top of the airbag 23, and a part of the gas in the connecting column 8 is blown towards the surface of the lamp 7 through the air blowing port 9. After applying the defogging agent, the air blowing port 9 continuously blows air towards the outer wall of the lamp 7. On the one hand, it further improves the defogging efficiency of the defogging agent and avoids the phenomenon of reduced defogging agent efficiency caused by weather reasons. On the other hand, it effectively reduces the temperature difference between the inside of the lamp 7 and the external environment, and at the same time avoids the phenomenon of water droplets hanging on the wall caused by too large a temperature difference, reducing the reduction of the refraction efficiency and scattering effect of the lamp 7. The connecting column 8 inflates the airbag 23 through the connecting pipe 21, so that the airbag 23 expands after being filled with gas, effectively fixing the stability of the lamp 7 placed in the connecting platform 5. Since the lamp 7 is prone to shaking in strong wind weather, it reduces the collision generated when the lamp 7 shakes on the inner wall of the connecting platform 5 and avoids surface damage; When the airbag 23 is filled with gas, the excess gas cannot continue to enter the airbag 23, and the gas continues to blow out from the air inlet hole 22 and push open the connecting column 8. The refraction plates 19 are arranged in a circular array on the side wall of the lamp 7. The excess gas from the air inlet hole 22 pushes the refraction plates 19 to rotate on the rotating shaft 24. Since the refraction plates 19 are arranged as prisms, the prisms can refract the light of the runway lights in multiple directions, making the light scatter in a larger range. The pilot can see the indication of the runway lights more clearly at different angles and positions. Especially under low visibility conditions, such as foggy days, rainy days or at night, this dynamic multi-angle refraction can effectively improve the penetration and visible distance of the light, helping the pilot more accurately judge the position and direction of the runway, and at the same time making the light intensity distribution around the runway lights more uniform, avoiding the uneven brightness that may occur in traditional lamps.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
