Description

Technical Field

[0001] The invention belongs to the technical field of obstruction lights, and in particular relates to a self-cleaning aviation obstruction light. Background Art

[0002] With the rapid development of the aviation industry, aviation safety has become a vital issue. As an important aviation safety device, the main function of aviation obstruction lights is to identify the existence of buildings, structures or other obstacles to warn pilots to avoid them at night or in bad weather conditions. However, traditional aviation obstruction lights often accumulate various stains and solid impurities on their surfaces during long-term use, which not only affects the visual effect of the lights and reduces their warning function, but also poses a potential threat to the normal operation of the lights.

[0003] First, the accumulation of stains and solid impurities will seriously reduce the brightness of aviation obstruction lights, resulting in a significant decrease in their visibility at night or in bad weather conditions, which in turn increases the risk of pilots misjudging the location of obstacles. In order to maintain the cleanliness and brightness of the lights, regular manual cleaning is traditionally required, which not only greatly increases maintenance costs, but may also pose safety hazards due to untimely or incomplete cleaning operations.

[0004] Secondly, traditional cleaning methods usually only use a cleaning cloth to wipe the surface. This single cleaning method is often difficult to effectively remove solid impurities on the surface of the lamp; especially for aviation obstruction lights installed at high altitudes, manual cleaning is not only difficult to operate, but also poses a high safety risk. Summary of the invention

[0005] The present invention provides a self-cleaning aviation obstruction light, aiming to solve the problem that the existing cleaning method has obvious shortcomings in maintaining the cleanliness of aviation obstruction lights, which is not only inefficient but also costly, and the cleaning of high-altitude lamps is difficult and dangerous.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The embodiment of the present invention provides a self-cleaning aviation obstruction light, such as Figure 1-8 As shown, it includes a fixed base 1, and a lamp body 2 is installed on the fixed base 1 through embedded fasteners;

[0040] A self-cleaning device is provided on the outside of the lamp body 2;

[0041] Self-cleaning device includes:

[0042] Support frames 3 are symmetrically distributed on both sides of the lamp body 2, and the support frames 3 are connected to the fixed base 1 through elastic buckles;

[0043] One of the support frames 3 is equipped with a threaded rod 4 extending in a vertical direction through a bearing, and a lifting slider 5 is connected to the threaded rod 4 through a thread;

[0044] A guide rod 6 is provided on the other support frame 3, a guide slider 7 is slidably connected to the guide rod 6, a cleaning ring 8 is connected between the guide slider 7 and the lifting slider 5, and a cleaning groove with a circular cross section is provided in the cleaning ring 8;

[0045] A number of return springs 9 are evenly distributed on the inner wall of the cleaning slot, and the return springs 9 have built-in dampers;

[0046] A self-cleaning bracket 10 is provided on the side of the return spring 9 away from the inner wall of the cleaning ring 8, and the self-cleaning bracket 10 is a hollow structure;

[0047] A memory alloy fiber brush 11 is disposed inside the self-cleaning bracket 10, and a plurality of water outlet holes 13 are evenly distributed around the inner side of the memory alloy fiber brush 11;

[0048] A water reservoir 14 is disposed on one side of the fixed base 1 adjacent to the lamp body 2 , and a centrifugal pump 15 is disposed on the side wall thereof. The water outlet of the centrifugal pump 15 is connected to the self-cleaning bracket 10 through a flexible pipe 16 .

[0049] It should be noted that, since the existing cleaning methods have obvious deficiencies in maintaining the cleanliness of aviation obstruction lights, they are not only inefficient but also costly. At the same time, cleaning high-altitude lamps is even more difficult and dangerous. The precise vertical height adjustment of the cleaning ring 8 of this solution is combined with the adaptive deformation ability of the memory alloy fiber brush 11 to ensure that comprehensive and efficient cleaning can be performed regardless of the height and shape of the lamp body 2. This design not only improves the cleaning coverage rate, but also effectively removes stains and solid impurities by closely fitting the lamp body cover and cooperating with cleaning water, thereby greatly improving the cleaning efficiency.

[0050] Secondly, the dual filtration system in the water reservoir 14 and the dual functions of the UV sterilization module 21 and the PTC heating module 22 jointly ensure the purity and safety of the cleaning water; this not only avoids the risk of secondary pollution, but also enables the warm cleaning water to accelerate the dissolution of solid impurities on the outside of the lamp body 2, further improving the cleaning effect; at the same time, the appropriate water temperature also ensures the gentleness of the cleaning process to the lamp body 2, avoiding damage to the lamp body 2. The introduction of the sensor detection module 25 enables the cleaning process to achieve intelligent monitoring and automatic control, ensuring the timeliness and accuracy of the cleaning process.

[0051] Specifically, in this embodiment, the scheme mainly includes a fixed base 1, and the lamp body 2 is firmly installed on the fixed base 1 through embedded fasteners. In order to ensure that it remains clean for a long time, a self-cleaning device is specially provided on the outside; the self-cleaning device includes two support frames 3 symmetrically distributed on both sides of the lamp body 2; wherein, a threaded rod 4 extending in a vertical direction is assembled on one support frame 3 through a bearing, and a lifting slider 5 that can be lifted and lowered is threadedly connected to the threaded rod 4; and a guide rod 6 is arranged on the other support frame 3, and a guide slider 7 is slidably connected to the guide rod 6; a cleaning ring 8 is commonly connected between the lifting slider 5 and the guide slider 7, and a cleaning groove with a circular cross section is provided in the cleaning ring 8;

[0052] When the servo motor 24 is started and drives the threaded rod 4 to rotate, the linkage between the lifting slider 5 and the guide slider 7 drives the cleaning ring 8 to move up and down, so that the outer wall of the lamp body 2 at different heights can be fully cleaned; during the cleaning process, by driving the threaded rod 4 to rotate, the lifting slider 5 drives the cleaning ring 8 and the self-cleaning bracket 10 thereon to move in the vertical direction, and at the same time, the guide slider 7 slides smoothly on the guide rod 6, ensuring the stability and cleaning effect of the cleaning ring 8;

[0053] A number of return springs 9 are evenly distributed on the inner wall of the cleaning groove, and a damper is integrated in the return spring 9, which not only increases the stability of the cleaning ring 8 during the cleaning process, but also provides a buffering effect; in addition, the elastic effect of the return spring 9 can also effectively clean the uneven outer wall of the lamp body 2; a self-cleaning bracket 10 is provided on the side of the return spring 9 away from the inner wall of the cleaning ring 8, which further enhances the cleaning ability;

[0054] The other side of the return spring 9 is connected to the self-cleaning bracket 10, and a memory alloy fiber brush 11 is installed inside the self-cleaning bracket 10. The memory alloy fiber brush 11 can adaptively deform according to the curvature of the cover surface of the lamp body 1 and fit closely to the cover surface of the lamp body 1; at the same time, a plurality of water outlet holes 13 are evenly distributed on the inner circumference of the memory alloy fiber brush 11;

[0055] A water reservoir 14 is also provided on the fixed base 1 to provide sufficient water for the cleaning process; a centrifugal pump 15 is installed on the side wall of the water reservoir 14, and the centrifugal pump 15 is started to pump the water in the water reservoir 14 into the self-cleaning bracket 10 through the flexible pipe 16, and the water is sprayed out from the water outlet 13, and works together with the memory alloy fiber brush 11 to efficiently clean the cover surface of the lamp body 1;

[0056] After cleaning is completed, by driving the threaded rod 4 in the reverse direction to rotate, the cleaning ring 8 and the self-cleaning bracket 10 thereon can be smoothly reset to return to the initial position, ready for the next cleaning activity.

[0057] In a further preferred embodiment of the present invention, Figure 7As shown, the upper end surface of the water reservoir 14 is open, and the inner wall of the water reservoir 14 is provided with an upper and lower annular support frame, each layer includes a plurality of support blocks 17 evenly distributed along the circumferential direction, an upper interception filter 18 is provided on the upper support block 17, and a lower interception filter 19 is provided on the lower support block 17.

[0058] In this embodiment, the water reservoir 14 is used to store and supply water resources required for cleaning, the upper interception filter 18 is responsible for initially filtering out larger impurities in the water, and the lower interception filter 19 is arranged on the lower support block 17. The pore size of the lower interception filter 19 is smaller than that of the upper filter, and it can further intercept the suspended matter settled at the bottom of the water reservoir 14. When the centrifugal pump 15 is started, water will be pumped from the water reservoir 14 and pumped into the self-cleaning bracket 10 through the flexible pipe 16.

[0059] In a further preferred embodiment of the present invention, Figure 7 As shown, the aperture of the upper interception filter 18 is larger than that of the lower interception filter 19, the aperture range of the upper filter is 10mm-15mm, and the aperture range of the lower filter is 6mm-8mm.

[0060] In this embodiment, through such a double filtering mechanism, the water reservoir 14 can ensure that the water quality provided to the self-cleaning system is purer, thereby improving the cleaning effect and the operating efficiency of the equipment.

[0061] In a further preferred embodiment of the present invention, Figure 7 As shown, the water inlet of the centrifugal pump 15 is connected to the water reservoir 14 through the water conduit 20 , and the water conduit 20 extends along the inner wall of the water reservoir 14 to 1 / 3 of the height of the inner cavity of the water reservoir 14 .

[0062] In this embodiment, such a design enables the centrifugal pump 15 to directly pump water from the relatively clear water area at the top of the reservoir 14, avoiding the extraction of impurities or silt that may be deposited at the bottom, thereby ensuring the water quality of the water supply.

[0063] In a further preferred embodiment of the present invention, Figure 7 As shown, the inner wall of the water reservoir 14 is equipped with a UV sterilization module 21 and a PTC heating module 22 .

[0064] In this embodiment, the dual functions of the UV sterilization module 21 and the PTC heating module 22 not only eliminate microorganisms in the water, but also ensure the suitability of the water temperature, thereby comprehensively improving the safety of the water quality. The warm cleaning water can accelerate the dissolution of solid impurities on the outside of the lamp body 2 and improve the cleaning efficiency.

[0065] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a sewage control valve 23 is provided at the bottom of the water reservoir 14 .

[0066] In this embodiment, by periodically opening the sewage control valve 23, the sediment in the water reservoir 14 can be effectively discharged, so that the inside of the water reservoir 14 can be kept clean and hygienic.

[0067] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a servo motor 24 is arranged on the support frame 3 located on the threaded rod 4, and the output end of the servo motor 24 is fixedly connected to the end of the threaded rod 4 through an elastic coupling.

[0068] In this embodiment, the servo motor 24 drives the rotation of the water intake threaded rod 4 to achieve precise height adjustment of the lifting slider 5 and the cleaning ring 8 in the vertical direction. This design allows the device to flexibly adjust the position of the cleaning ring 8 according to actual needs to ensure efficient and comprehensive cleaning of the aviation obstruction light body 2.

[0069] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a sensor detection module 25 is provided on the side wall of the support frame 3, and is electrically connected to the self-cleaning device.

[0070] In this embodiment, during the entire working process, the sensor detection module 25 will continuously monitor the response of the self-cleaning device and fine-tune the cleaning strategy according to the feedback data to ensure that the cleaning effect reaches the best state.

[0071] In a further preferred embodiment of the present invention, Figure 2 As shown, the sensing detection module 25 includes a microprocessor and a photoelectric stain sensor arranged on the side wall of the supporting frame 3.

[0072] In this embodiment, the photoelectric stain sensor uses the principle of photoelectric effect and can keenly sense the stains on the surface of the aviation obstruction light or the surrounding environment. When the stains accumulate to a certain extent, the photoelectric stain sensor (TSL2561) will capture the changes in light reflection or scattering, thereby generating a corresponding electrical signal. The electrical signal generated by the photoelectric stain sensor will be transmitted to the microprocessor (STM32F407) on the side wall of the support frame 3. The microprocessor transmits control instructions to the self-cleaning device. These instructions may include starting the cleaning operation, adjusting the cleaning force, changing the cleaning path, etc. After receiving the instructions, the self-cleaning device will respond quickly and perform the corresponding cleaning task.

[0079] In addition, the side wall of the support frame 3 is also equipped with a photoelectric dirt sensor, which uses the principle of photoelectric effect to keenly sense the dirt on the surface of the aviation obstruction light body 2; when the dirt accumulates to a certain extent, the photoelectric dirt sensor will capture the changes in light reflection or scattering, generate corresponding electrical signals and transmit them to the microprocessor; the microprocessor analyzes and judges the received signals and sends control instructions to the self-cleaning device, such as starting the cleaning operation, adjusting the cleaning force, changing the cleaning path, etc.; after receiving the instructions, the self-cleaning device responds quickly and performs the corresponding cleaning tasks;
