[0028] Example 1:

[0029] This utility model embodiment provides an electric high-pressure cleaning vehicle spray water cleaning device, such as... Figures 1-5 As shown, it includes: a first diversion pipe 1, a connecting frame 2 and a water supply pipe 3 are provided on the first diversion pipe 1, the water supply pipe 3 is connected to the first diversion pipe 1, a plurality of first nozzles 4 are provided on the lower surface of the first diversion pipe 1, the input end of the first nozzle 4 is connected to the inside of the first diversion pipe 1, a second diversion pipe 5 is provided on one side of the first diversion pipe 1, the second diversion pipe 5 is perpendicular to the first diversion pipe 1, the second diversion pipe 5 is connected to the first diversion pipe 1 through a water inlet hose, a plurality of second nozzles 6 are provided on the side of the second diversion pipe 5 away from the first diversion pipe 1, the input end of the second nozzle 6 is connected to the inside of the second diversion pipe 5, a connecting plate 7 is provided on the side of the second diversion pipe 5 close to the first diversion pipe 1, one end of the connecting plate 7 is rotatably connected to the upper surface of the first diversion pipe 1 through a rotating shaft 8, a spring rod 9 is provided on the first diversion pipe 1, one end of the spring rod 9 is hinged to the upper surface of the first diversion pipe 1, and the other end of the spring rod 9 is hinged to the side wall of the connecting plate 7;

[0030] Several first nozzles 4 are arranged at equal intervals along the length of the first diversion pipe 1;

[0031] The output end of the second nozzle 6 is tilted downwards;

[0032] Several second nozzles 6 are arranged at equal intervals along the axial direction of the second diversion pipe 5;

[0033] The left and right ends of the first shunt tube 1 are set as arc surfaces.

[0034] The working principle and beneficial effects of the above technical solution are as follows: The connecting frame 2 is fixedly connected to the first diversion pipe 1. One end of the connecting frame 2 can be connected to the front frame of the cleaning vehicle, thereby realizing the installation of the water spray cleaning device. One end of the water supply pipe 3 is connected to the water tank on the cleaning vehicle to obtain the clean water required for cleaning. When the high-pressure cleaning vehicle performs road cleaning operations, the water supply pipe 3 delivers high-pressure water to the first diversion pipe 1. The first nozzles 4, which are equally spaced along the length of the first diversion pipe 1, spray water vertically downwards to cover the road surface. At the same time, part of the water in the first diversion pipe 1 flows into the second diversion pipe 5 through the water inlet hose. The second diversion pipe 5 distributes the water to several second nozzles 6, which are equally spaced along the axial direction. Since the output end of the second nozzle 6 is tilted downwards, the water sprayed by the second nozzle 6 can be accurately directed towards the shoulder and side guardrail area, thereby cleaning the shoulder and side guardrail. The washing process expands the cleaning range of the cleaning device, thereby achieving comprehensive cleaning of the entire road. During the operation of the cleaning vehicle, the second diversion pipe 5 will inevitably encounter obstacles. When the second diversion pipe 5 comes into contact with an obstacle, as the cleaning vehicle moves forward, the second diversion pipe 5 can drive the connecting plate 7 to swing towards the cleaning vehicle, so that the second diversion pipe 5 gradually moves to the rear of the first diversion pipe 1 until it passes through the obstacle. During the swing of the second diversion pipe 5 towards the cleaning vehicle, the connecting plate 7 drives the spring rod 9 to gradually compress. After passing through the obstacle, under the elastic force of the spring rod 9, the connecting plate 7 drives the second diversion pipe 5 to return to its original position and continue to clean the road shoulder or side guardrail. The left and right ends of the first diversion pipe 1 are set with arc surfaces, so they will not obstruct the movement of the second diversion pipe 5, ensuring the smooth movement of the second diversion pipe 5.

[0035] Example 2:

[0036] Based on the above embodiment 1, as follows Figure 2 , Figure 3 As shown, protective plates 10 are symmetrically arranged on the front and rear sides of the second diversion pipe 5, and one side wall of the protective plate 10 is fixedly connected to the outer wall of the second diversion pipe 5.

[0037] The two protective plates 10 are connected at their upper ends by a reinforcing plate 11;

[0038] The length of the protection plate 10 is greater than the length of the second shunt tube 5.

[0039] The working principle and beneficial effects of the above technical solution are as follows: When encountering external obstacles, the protective plate 10 will contact the obstacle before the second nozzle 6 and the second diversion pipe 5, thereby protecting the second nozzle 6 and the second diversion pipe 5, preventing the second nozzle 6 or the second diversion pipe 5 from being deformed or damaged due to collision, extending the service life of the second nozzle 6 and the second diversion pipe 5, reducing the maintenance frequency, and the setting of the protective plate 10 will not interfere with the normal water spraying path of the second nozzle 6. The water flow can be smoothly sprayed from the gaps between the protective plates 10 to the road shoulder and guardrail area without affecting the realization of the original cleaning function. The upper end of the protective plate 10 is connected by a reinforcing plate 11, so that the protective plates 10 on the front and rear sides of the second diversion pipe 5 form a stable frame structure, preventing the deformation or displacement of a single protective plate 10 when subjected to force, and improving the stability of the protective plate 10.

[0040] Example 3:

[0041] Based on Example 1 or 2, such as Figures 2-5 As shown, a protective mechanism is provided on the upper surface of the first diversion pipe 1. The protective mechanism is located on the side of the connecting plate 7 away from the spring rod 9. The protective mechanism includes a mounting shell 12, which is fixedly connected to the upper surface of the first diversion pipe 1. A sliding hole is provided on the side of the mounting shell 12 near the connecting plate 7. A buffer rod 13 is slidably installed in the sliding hole. A buffer block 14 is provided on the side of the buffer rod 13 near the connecting plate 7. A reset spring 15 is sleeved on the buffer rod 13. One end of the reset spring 15 is connected to the buffer block 14, and the other end of the reset spring 15 is connected to the outer wall of the mounting shell 12.

[0042] The working principle and beneficial effects of the above technical solution are as follows: After the second diversion pipe 5 separates from the obstacle, under the action of the spring rod 9, the connecting plate 7 quickly rotates away from the cleaning vehicle. The connecting plate 7 first contacts the buffer block 14. The impact force generated by the contact can push the buffer block 14 and the buffer rod 13 to move towards the mounting shell 12, and drive the return spring 15 to compress. The elastic force of the return spring 15 can absorb part of the impact force, and finally restore the connecting plate 7 to its original position. By setting the protection mechanism, the swing amplitude of the connecting plate 7 can be limited, preventing the connecting plate 7 from swinging too much during the reset process and causing the water inlet hose to break. This ensures the stable connection between the water inlet hose and the second diversion pipe 5 and extends the service life of the cleaning device.

[0043] Example 4:

[0044] Based on Example 3, such as Figures 2-5As shown, the buffer block 14 is made of magnetic material. The outer wall of the connecting plate 7 is provided with a magnet 16 corresponding to the buffer block 14. The buffer rod 13 extends into the mounting shell 12 from the end away from the buffer block 14 and is provided with a first friction block 17. The first friction block 17 is provided with a first friction surface on one side at an angle. The inner wall of the mounting shell 12 is fixedly provided with a second friction block 18. The second friction block 18 is provided with a second friction surface on one side at an angle that matches the first friction surface.

[0045] The working principle and beneficial effects of the above technical solution are as follows: During the rotation of the connecting plate 7 away from the cleaning vehicle, the magnet 16 on the side wall of the connecting plate 7 first contacts the buffer block 14. The buffer block 14 is made of magnetic materials such as iron. Under the magnetic force of the magnet 16, the buffer block 14 is attracted to the magnet 16, and then the buffer block 14 moves towards the mounting shell 12. The buffer block 14 drives the first friction block 17 to slide inside the mounting shell 12 through the buffer rod 13. The first friction surface of the first friction block 17 gradually contacts the second friction surface of the second friction block 18. Both the first friction block 17 and the second friction block 18 can be made of anti-slip rubber material. When the first friction surface slides along the second friction surface, the force between the first friction block 17 and the second friction block 18 gradually increases. The force between the second friction block 18 and the first friction block 17 further slows down the rotation speed of the connecting plate 7 until the first friction block 17 can no longer slide. At this time, under the friction between the first friction surface and the second friction surface, the first friction block 17 is stuck between the second friction block 18 and the inner wall of the mounting shell 12, causing the connecting plate 7 to stop moving directly. This avoids the small-amplitude swing of the connecting plate 7, improves the stability of the second diversion pipe 5 and the second nozzle 6, and allows the second nozzle 6 to spray water stably onto the road shoulder or guardrail, improving the cleaning effect. When encountering an obstacle, the magnet 16 will separate from the magnetic buffer block 14 upon contact with the obstacle, preventing the second diversion pipe 5 from being violently impacted, effectively protecting the second diversion pipe 5 and the second nozzle 6, and extending the service life of the cleaning device.
