Description
Technical Field
[0001] This utility model relates to the field of drone cleaning technology, specifically a light rail elevated facade cleaning mechanism based on air-ground collaborative drones. Background Technology
[0002] In modern urban transportation systems, light rail, as a convenient and efficient public transportation tool, has an elevated structure that is constantly exposed to the outdoor environment, making its facade prone to accumulating pollutants such as dust, oil stains, and bird droppings. These pollutants not only affect the aesthetics of the elevated light rail system, but long-term adhesion can also cause corrosion to the structural surface, shorten its service life, and even affect driving safety in severe weather.
[0003] Traditional methods for cleaning the exterior facades of elevated light rail systems primarily rely on manual labor, requiring operators to use aerial work platforms or scaffolding. This approach has several drawbacks: firstly, working at heights carries extremely high risks, making it difficult to fully guarantee the personal safety of operators, and is significantly limited by factors such as weather and terrain; secondly, manual cleaning is inefficient, requiring substantial manpower, resources, and time, especially for long light rail systems, resulting in high maintenance costs.
[0004] Based on this, a light rail elevated facade cleaning mechanism based on air-ground collaborative UAVs is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0005] The purpose of this invention is to provide a light rail elevated facade cleaning mechanism based on air-ground collaborative UAVs, so as to solve the problems in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A light rail elevated facade cleaning mechanism based on air-ground cooperative UAV includes a chassis, flight support, propellers, and cleaning components. Two symmetrical landing gears are fixedly connected to the lower surface of the chassis, and four flight support is fixedly connected to the side wall of the chassis. Each of the four flight support is equipped with a propeller controlled by an independent motor. A vision sensor is installed on the lower surface of the chassis, and a fixing plate is fixedly connected between the two landing gears through a bracket. The cleaning assembly is mounted on the upper surface of the fixed plate and is used for efficient cleaning of the exterior facade of the light rail elevated structure.
[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative embodiment: the cleaning assembly includes a water pipe, a spray pipe, and a rotating base. The rotating base is rotatably mounted on the upper surface of the fixed plate via a rotating shaft. The spray pipe is fixedly connected to the rotating base. One end of the spray pipe is connected to a water pipe, and the other end of the water pipe is connected to a water pump. A cleaning motor is fixedly connected to the bottom wall of the fixed plate via a bracket. The output end of the cleaning motor passes through the fixed plate and is fixedly connected to a turntable. A rotating slide rod is fixedly connected to the turntable at an offset position from the center. A guide rail is fixedly connected to the rotating base, and the rotating slide rod is slidably connected to the inner wall of the guide rail.
[0008] In one alternative: an incomplete bevel gear ring is fixedly connected to the upper surface of the fixed plate; a rotating pipe is rotatably provided on the water spray pipe via a bearing; the rotating pipe is connected to the water spray pipe; a bevel gear is fixedly connected to the periphery of the rotating pipe; and the bevel gear meshes with the incomplete bevel gear ring.
[0009] In one alternative: a counterweight is fixedly connected to the end of the water spray pipe away from the rotating pipe.
[0010] In one alternative: the landing gear is fixedly connected to a support plate, and the support plate is provided with a buffer block.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention eliminates the need for manual high-altitude operations. By using a drone equipped with cleaning components, the exterior facade of the light rail elevated structure can be cleaned, fundamentally preventing accidents such as falls from heights and ensuring the personal safety of operators.
[0012] The water spray pipe in the cleaning assembly of this invention can reciprocate under the drive of the cleaning motor, which expands the spraying range of the cleaning liquid. It can cover a large cleaning area without frequent movement of the drone, reducing operation steps, increasing the cleaning area per unit time, and improving cleaning efficiency.
[0013] During the oscillation of the water spray pipe, the rotating pipe of this invention achieves its own rotation through the meshing of a bevel gear and an incomplete bevel gear ring. The sprayed rotating water flow can more effectively impact the pollutants on the exterior facade, enhance the cleaning effect, and shorten the cleaning time. With the reciprocating oscillation of the water spray pipe and the rotation of the rotating pipe, large-scale, multi-angle automatic cleaning is achieved, reducing the labor intensity of operators.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] In one embodiment, such as Figures 1-4 As shown, a light rail elevated facade cleaning mechanism based on air-ground cooperative UAV includes a chassis 1, flight support 2, propeller 3, and cleaning components 5. Two symmetrical landing gears 6 are fixedly connected to the lower surface of the chassis 1, and four flight support 2 are fixedly connected to the side wall of the chassis 1. Each of the four flight support 2 is equipped with a propeller 3 controlled by an independent motor. A vision sensor 4 is installed on the lower surface of the chassis 1, and a fixing plate 10 is fixedly connected between the two landing gears 6 through a bracket. The cleaning component 5 is installed on the upper surface of the fixed plate 10 and is used to efficiently clean the exterior of the light rail elevated structure.
[0021] The independent motor of propeller 3 is started to drive the drone to rise. After it is raised to the same height as the outer facade of the elevated structure, the water pump at the water source is started to send cleaning fluid or clean water through water pipe 11 into water spray pipe 13 and rotating pipe 12, and then sprayed out from rotating pipe 12 to clean the elevated structure. No manual high-altitude operation is required, which is safer and more efficient.
[0022] In one embodiment, the cleaning assembly 5 includes a water pipe 11, a spray pipe 13, and a rotating seat 20. The rotating seat 20 is rotatably mounted on the upper surface of the fixed plate 10 via a rotating shaft. The spray pipe 13 is fixedly connected to the rotating seat 20. One end of the spray pipe 13 is connected to the water pipe 11, and the other end of the water pipe 11 is connected to a water pump. The bottom wall of the fixed plate 10 is fixedly connected to a cleaning motor 9 via a bracket. The output end of the cleaning motor 9 passes through the fixed plate 10 and is fixedly connected to a turntable 18. The turntable 18 is fixedly connected to a rotating slide rod 17 at an offset position from the center. The rotating seat 20 is fixedly connected to a guide rail 16, and the rotating slide rod 17 is slidably connected to the inner wall of the guide rail 16.
[0023] While the rotating pipe 12 sprays water for cleaning, the cleaning motor 9 is started. The cleaning motor 9 drives the turntable 18 to rotate, and the turntable 18 drives the rotating slide rod 17 to rotate. The rotating slide rod 17 rotates and slides within the track of the guide rail 16, causing the guide rail 16 to reciprocate around the axis of the rotating seat 20. The guide rail 16 drives the rotating seat 20 to reciprocate around the axis of the rotating seat 20. The rotating seat 20 drives the water spray pipe 13 to oscillate back and forth within a certain range around the axis of the rotating seat 20, so that the cleaning liquid sprayed from the rotating pipe 12 covers a larger area and the cleaning area is wider. Large-area cleaning can be achieved without the need for frequent manual operation of the drone, reducing the difficulty of drone cleaning operations.
[0024] In one embodiment, an incomplete bevel gear ring 15 is fixedly connected to the upper surface of the fixed plate 10, and a rotating pipe 12 is rotatably provided on the water spray pipe 13 via a bearing. The rotating pipe 12 is connected to the water spray pipe 13, and a bevel gear 14 is fixedly connected to the periphery of the rotating pipe 12. The bevel gear 14 meshes with the incomplete bevel gear ring 15.
[0025] As the water spray pipe 13 swings back and forth around the rotating seat 20, the bevel gear 14 on the rotating pipe 12 meshes with the incomplete bevel gear ring 15, causing the rotating pipe 12 to rotate. The rotating pipe 12 sprays out rotating water flow to clean the exterior of the light rail elevated structure, improving the cleaning effect.
[0026] In one embodiment, a counterweight 19 is fixedly connected to the end of the water spray pipe 13 away from the rotating pipe 12.
[0027] The counterweight 19 ensures that the rotating pipe 12 and the water spray pipe 13 remain balanced on both sides of the machine body as they swing around the axis of the counterweight 19.
[0028] In one embodiment, the landing gear 6 is fixedly connected to a support plate 7, and the support plate 7 is provided with a buffer block 8.
[0029] Buffer block 8 can provide cushioning when the drone lands.
[0030] The above embodiments disclose a light rail elevated facade cleaning mechanism based on air-ground cooperative UAVs. Its specific working principle and process are as follows: S1: Start the independent motor of propeller 3 to drive the drone to rise. After it is raised to the same height as the outer facade of the elevated structure, start the water pump at the water source to send the cleaning solution or clean water through the water pipe 11 into the spray pipe 13 and the rotating pipe 12, and then spray it out from the rotating pipe 12 to clean the elevated structure. No manual high-altitude operation is required, which is safer and more efficient. S2: While the rotating pipe 12 is spraying water for cleaning, the cleaning motor 9 is started. The cleaning motor 9 drives the turntable 18 to rotate, the turntable 18 drives the rotating slide rod 17 to rotate, and the rotating slide rod 17 slides within the track of the guide rail 16, causing the guide rail 16 to reciprocate around the axis of the rotating seat 20. The guide rail 16 drives the rotating seat 20 to reciprocate around the axis of the rotating seat 20, and the rotating seat 20 drives the water spray pipe 13 to swing back and forth within a certain range around the axis of the rotating seat 20. This makes the cleaning liquid sprayed from the rotating pipe 12 spray a larger area and clean a wider area. It can achieve large-area cleaning without the need for frequent manual operation of the drone, reducing the difficulty of drone cleaning operation. S3: When the water spray pipe 13 swings back and forth around the rotating seat 20, the bevel gear 14 on the rotating pipe 12 meshes with the incomplete bevel gear ring 15, the rotating pipe 12 rotates, and the rotating pipe 12 sprays out rotating water flow to clean the exterior of the light rail elevated structure, thus improving the cleaning effect. The counterweight 19 ensures that the rotating pipe 12 and the water spray pipe 13 remain balanced on both sides of the machine body as they swing around the axis of the counterweight 19.
[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
