Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning technology for highway maintenance, and in particular to a high-pressure cleaning device for highway maintenance. Background Technology

[0002] Maintaining road cleanliness is crucial for ensuring traffic safety and extending road lifespan in highway maintenance. With increasingly heavy highway traffic, dirt, mud, oil stains, and other pollutants accumulate on road surfaces, severely impacting their aesthetics and usability. High-pressure cleaning devices, as key equipment in highway maintenance, effectively remove various pollutants from road surfaces using high-pressure water jet technology. By pressurizing water and spraying it at high speed onto the road surface, the impact force of the water jet strips away dirt, playing an indispensable role in highway maintenance.

[0003] Currently, most commercially available high-pressure cleaning devices for highway maintenance employ a fixed-installation cleaning arm and nozzle structure. The technical principle involves a vehicle-mounted high-pressure water pump pressurizing water, which is then transported through fixed pipes to nozzles installed on the bottom, side, or front of the vehicle. These nozzles then spray the high-pressure water onto the road surface for cleaning. The cleaning arm is generally a rigid structure, with its length and extension angle determined during design and manufacturing. The cleaning position is changed by moving the vehicle during operation. This mechanical structure and technical principle can, to a certain extent, meet the routine cleaning needs of highway surfaces and has played an important role in past highway maintenance work, effectively removing general stains from the road surface.

[0004] However, existing high-pressure cleaning devices for highway maintenance have significant limitations. Due to their fixed cleaning arm length and extension angle, they struggle to effectively cover certain special locations, such as under road medians and in narrow or recessed areas inaccessible to water trucks, like crevices in curbs. These areas often accumulate large amounts of dirt and debris, and conventional high-pressure cleaning devices, due to structural limitations, cannot move the nozzles to suitable positions for cleaning. Previously, in such cases, additional personnel with small cleaning equipment or tools were typically required to specifically treat these difficult-to-clean areas. This not only incurs significant labor costs but also results in low efficiency and long cleaning times, severely impacting the overall progress and efficiency of highway maintenance work and increasing costs. Therefore, this paper proposes a high-pressure cleaning device for highway maintenance to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-pressure cleaning device for highway maintenance, which aims to improve the problem of the inability to move the high-pressure nozzle in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-pressure cleaning device for highway maintenance includes a cleaning vehicle, a water tank fixedly connected to the top of the cleaning vehicle, a movable component provided at the bottom of the cleaning vehicle, a water pump fixedly connected to the inner wall of the water tank, an input end of the water pump fixedly connected to the outer wall of the water tank, a telescopic pipe fixedly connected to the output end of the water pump, a high-pressure nozzle provided at the bottom of the telescopic pipe, and a quick-release component provided on the outer wall of the high-pressure nozzle.

[0008] The moving component includes a slider, the top of which is fixedly connected to the bottom of the cleaning cart. A slide rail is slidably connected to the outer wall of the slider, and a fixing block is fixedly connected to the bottom of the slide rail. A connecting pipe is fixedly connected to the bottom of the fixing block. The outer wall of the connecting pipe is disposed on the top of the high-pressure nozzle, and the inner wall of the connecting pipe is fixedly connected to the outer wall of the telescopic pipe. A fixing plate is fixedly connected to the bottom of the cleaning cart, and an electric push rod is fixedly connected to the bottom of the fixing plate. A push plate is fixedly connected to the output end of the electric push rod, and one end of the push plate is fixedly connected to the outer wall of the fixing block.

[0009] As a further description of the above technical solution:

[0010] The quick-release assembly includes a second slider, which is disposed on the outer wall of the high-pressure nozzle. A second connecting pipe is disposed on the inner wall of the second slider. The outer wall of the second connecting pipe is slidably connected to the inner wall of the second slider. A stop block is fixedly connected to the inner wall of the second slider.

[0011] As a further description of the above technical solution:

[0012] A spring is fitted on the outer wall of the second connecting pipe. One end of the spring is fixedly connected to the outer wall of the second connecting pipe, and the other end of the spring is fixedly connected to the top of the stop block.

[0013] As a further description of the above technical solution:

[0014] The second connecting pipe is fixedly connected to a waterproof ring, and the second fixing block is fixedly connected inside the second connecting pipe. A water pipe is slidably connected to the inner wall of the second fixing block.

[0015] As a further description of the above technical solution:

[0016] A nozzle is fixedly connected to the bottom of the water pipe, and a second spring is sleeved on the outer wall of the water pipe. One end of the second spring is fixedly connected to the bottom of the second fixing block, and the other end of the second spring is fixedly connected to the top of the nozzle.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the second connecting pipe is provided with a retaining ball, and a high-pressure nozzle is slidably connected to the inner wall of the second connecting pipe;

[0019] As a further description of the above technical solution:

[0020] The high-pressure nozzle has a fixing groove inside, and the fixing groove engages with the retaining ball.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the electric push rod drives the connecting pipe to move in parallel, and then the movement of the connecting pipe drives the high-pressure nozzle to move, achieving the effect of adjusting the position of the high-pressure nozzle. This avoids the problem that conventional cleaning ranges are fixed and cannot cover some special areas, such as the area under the road median strip, the gaps between the curb stones, and other narrow or recessed areas that sprinkler trucks cannot reach, which would prevent these areas from being effectively cleaned and require additional manual cleaning. Therefore, there is no need to arrange additional manpower or other equipment to specially treat these difficult-to-clean areas, saving cleaning time and labor costs and improving overall cleaning efficiency.

[0023] 2. In this utility model, by pushing the slider upward to release the limiting position of the ball, and then moving the ball out of the fixing groove to release the fixing of the high-pressure nozzle, the high-pressure nozzle can be quickly replaced. This avoids the situation where an unsuitable high-pressure nozzle cannot provide the ideal cleaning effect, and some dirt cannot be completely removed, affecting the cleaning quality and failing to meet the requirements of different cleaning scenarios. According to different cleaning tasks and working conditions, the appropriate nozzle can be quickly replaced, thereby ensuring the cleaning effect and improving the cleaning quality.

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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a high-pressure cleaning device for highway maintenance, comprising a cleaning vehicle 1. The cleaning vehicle 1 typically consists of a chassis, a water tank 2, a water pump 3, a cleaning device, and a control system, and is used for cleaning highway surfaces. This is existing technology and will not be described in detail here. The water tank 2 is fixedly connected to the top of the cleaning vehicle 1, and a movable component is provided at the bottom of the cleaning vehicle 1. The water pump 3 is fixedly connected to the inner wall of the water tank 2, and the input end of the water pump 3 is fixedly connected to the outer wall of the water tank 2. The output end of the water pump 3 is fixedly connected to a telescopic pipe 4, which is a plastic telescopic water pipe capable of resisting external pressure and stretching to a certain extent. This is existing technology and will not be described in detail here. A high-pressure nozzle 19 is provided at the bottom of the telescopic pipe 4, and a quick-release component is provided on the outer wall of the high-pressure nozzle 19.

[0034] The moving component includes a slider 8, the top of which is fixedly connected to the bottom of the cleaning cart 1. A slide rail 7 is slidably connected to the outer wall of the slider 8. The slider 8 moves in coordination with the slide rail 7, thereby driving the connecting pipe 5 to move in parallel, achieving the effect of extending the connecting pipe 5 outward. A fixing block 6 is fixedly connected to the bottom of the slide rail 7, and the connecting pipe 5 is fixedly connected to the bottom of the fixing block 6. The fixing block 6 is used to connect the slide rail 7 and the connecting pipe 5, achieving the effect of driving the connecting pipe 5 to move in parallel. The outer wall of the connecting pipe 5 is set on the top of the high-pressure nozzle 19, and the inner wall of the connecting pipe 5 is fixedly connected to the outer wall of the telescopic pipe 4. A fixing plate 9 is fixedly connected to the bottom of the cleaning cart 1, and an electric push rod 10 is fixedly connected to the bottom of the fixing plate 9. A push plate 11 is fixedly connected to the output end of the electric push rod 10. One end of the push plate 11 is fixedly connected to the outer wall of the fixing block 6. The electric push rod 10 moves in coordination with the push plate 11, thereby driving the fixing block 6 to move in parallel, achieving the effect of extending the connecting pipe 5 outward.

[0035] Reference Figure 1 and Figures 4-6 The quick-release assembly includes a second slider 13, which is located on the outer wall of the high-pressure nozzle 19. A second connecting pipe 12 is located on the inner wall of the second slider 13, and the outer wall of the second connecting pipe 12 is slidably connected to the inner wall of the second slider 13. A stop block 23 is fixedly connected to the inner wall of the second slider 13. The second slider 13, in conjunction with the stop block 23, limits the movement of the retaining ball 22, thus securing the high-pressure nozzle 19. A first spring 14 is fitted onto the outer wall of the second connecting pipe 12. The first spring 14 drives the second slider 13 to reset, thereby engaging the retaining ball 22 into the fixing groove 18, thus securing the high-pressure nozzle 19. One end of the first spring 14 is fixedly connected to the outer wall of the second connecting pipe 12, and the other end is fixedly connected to the top of the stop block 23. A waterproof ring 21 is fixedly connected to the second connecting pipe 12, sealing the connection between the high-pressure nozzle 19 and the second connecting pipe 12 to prevent water from flowing out. The water flows out from the connection point. A fixing block 15 is fixedly connected inside the connecting pipe 2 12. A water pipe 16 is slidably connected to the inner wall of the fixing block 2 15. A nozzle 17 is fixedly connected to the bottom of the water pipe 16. A spring 20 is sleeved on the outer wall of the water pipe 16. One end of the spring 20 is fixedly connected to the bottom of the fixing block 2 15, and the other end of the spring 20 is fixedly connected to the top of the nozzle 17. The fixing block 2 15, in conjunction with the rebound of the spring 20, drives the nozzle 17 to extend and retract, thus adapting to different types of high-pressure nozzles 19. A retaining ball 22 is provided on the inner wall of the connecting pipe 2 12. A high-pressure nozzle 19 is slidably connected to the inner wall of the connecting pipe 2 12. A fixing groove 18 is opened inside the high-pressure nozzle 19. The fixing groove 18 and the retaining ball 22 engage. When it is necessary to install or remove the high-pressure nozzle 19, simply push the slider 2 13 upward to make the retaining ball 22 slide out of the fixing groove 18 to achieve quick installation or removal.

[0036] Working principle: When a cleaning area needs to be moved, firstly, the electric push rod 10 is turned on, which pushes the push plate 11 to move in parallel. Then, the movement of the push plate 11 drives the fixed block 6 to move. Next, the movement of the fixed block 6 drives the slide rail 7 to slide on the outer wall of the slider 8. Then, the movement of the fixed block 6 drives the connecting pipe 5 to move, and then the movement of the connecting pipe 5 drives the high-pressure nozzle 19 to move. This prevents the water truck from failing to clean specific areas and speeds up the work efficiency.

[0037] When the high-pressure nozzle 19 needs to be replaced, first push the slider 2 13 upwards. Pushing the slider 2 13 upwards will compress the spring 1 14. Then, the movement of the slider 2 13 will move the stop 23. Subsequently, the stop 23 will release the limit on the retaining ball 22, and the retaining ball 22 will move out of the fixing groove 18. Then, take out the high-pressure nozzle 19 downwards. When installing the required high-pressure nozzle 19, simply push the high-pressure nozzle 19 upwards along the inner wall of the connecting pipe 2 12. Then, the high-pressure nozzle 19 will compress the nozzle 17. The elastic force of the spring 2 20 will limit the nozzle 17. Then, release the slider 2 13. The rebound of the spring 1 14 will cause the slider 2 13 to reset. Then, the reset of the slider 2 13 will cause the stop 23 to limit the retaining ball 22. Finally, the retaining ball 22 will engage with the fixing groove 18 to complete the fixing of the high-pressure nozzle 19. This avoids the need to waste a lot of time due to the cumbersome process when replacing the high-pressure nozzle 19.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
