[0002] In order to improve the urban image and strengthen the construction of ecological civilization, many cities regard road cleaning as the top priority of their work, and road sprinkling and dust removal is an essential daily task. There are various types of cleaning sprinkler trucks with diverse functions to adapt to complex road conditions.

[0003] When the sprinkler truck brakes, starts, or goes up and down slopes, the water in the water tank will flow towards one end of the water tank under the influence of inertia and gravity. When the water converges forward or backward, it will cause the water outlet to be unable to suck water, resulting in unstable water output and discontinuous sprinkling work. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sprinkler truck with adjustable water output, which is used to solve the problems that when the sprinkler truck works on slopes, the water converges forward or backward, resulting in the water outlet being unable to suck water, unstable water output, and discontinuous sprinkling work.

Two water permeable plates are fixedly connected to the water storage device inside the two piston valves. The water permeable plates are slidably connected to the sliding rod. The piston valves slide outside the water permeable plates. Water inlet holes are opened at both ends of the water storage device. A water outlet is provided at the bottom of the water storage device. The water outlet is connected to a spraying assembly.

[0006] The sprinkler truck with adjustable water output provided by the utility model also has the following technical features:

[0007] Further, the piston valve includes a counterweight plate and a rubber gasket. The rubber gasket is inside the counterweight plate. The counterweight plate is fixedly connected to the sliding rod, and the rubber gasket seals the water permeable plate.

[0008] Further, the lengths of the sliding rod and the piston valve are the same as the distance from the water permeable plate to the other end of the water storage device.

[0012] Further, an inspection opening is fixedly connected to the top of the water tank.

[0013] The utility model has the following beneficial effects: In the water sprinkler with adjustable water output described in this application, a slidable piston valve slides in the water storage device, enabling the water inlet holes at the front and rear ends to communicate with or be isolated from the water permeable plate.

[0017] The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 2 In the embodiment of the water sprinkler with adjustable water output of the present utility model as shown, the water sprinkler with adjustable water output includes a vehicle body 1 and a water tank 2. The water tank 2 is installed on the vehicle body 1. The bottom of the water tank 2 is fixedly connected with a water storage device 3. Two piston valves 4 are slidably connected to both ends of the water storage device 3. A sliding rod 5 is connected between the two piston valves 4. Two water permeable plates 6 are fixedly connected in the water storage device 3 inside the two piston valves 4. The water permeable plates 6 are slidably connected with the sliding rod 5. The piston valves 4 slide outside the water permeable plates 6. Water inlet holes 7 are opened at both ends of the water storage device 3. A water outlet 8 is provided at the bottom of the water storage device 3. The water outlet 8 is connected with a spraying assembly 9.

[0019] Specifically, when the sprinkler truck is going uphill, the water in the water tank 2 flows towards the rear of the vehicle under the action of gravity. The piston valve 4 in the water storage device 3 slides towards the rear of the vehicle under the action of gravity and the inertia of the water flow. At this time, the piston valve 4 at the front of the vehicle moves to the position of the water permeable plate 6 at the same end to seal the water permeable plate 6, while the piston valve 4 at the rear end of the vehicle slides away from the water permeable plate 6, enabling the water in the water tank 2 to enter the water storage device 3 through the water inlet hole 7 and reach the water outlet 8 through the water permeable plate 6. Since the water permeable plate 6 at the front end is sealed, air cannot enter the water storage device 3, and the spraying assembly 9 can continuously draw water from the water outlet 8. When the sprinkler truck is going downhill, the movement of the piston valve 4 is opposite, consistent with the direction of water flow convergence, ensuring the water supply at the water outlet when the water in the sprinkler truck converges towards one end and avoiding the interruption of the watering operation.

[0020] In an embodiment of the present application, preferably, the piston valve 4 includes a counterweight plate 41 and a rubber gasket 42. The rubber gasket 42 is inside the counterweight plate 41. The counterweight plate 41 is fixedly connected to the sliding rod 5. The rubber gasket 42 seals the water permeable plate 6, which is used to accelerate the sliding speed of the piston valve 4 and better seal the water permeable plate 6 to prevent air leakage.

[0021] In an embodiment of the present application, preferably, the lengths of the sliding rod 5 and the piston valve 4 are the same as the distance from the water permeable plate 6 to the other end of the water storage device 3, so that when the piston valve 4 at one end seals the water permeable plate 6, the piston valve 4 at the other end slides to the top of the water storage device 3, enabling all the water inlet holes 7 to be communicated with the water permeable plate 6 and increasing the water intake.

[0022] In an embodiment of the present application, preferably, the water inlet hole 7 is outside the water permeable plate 6 to prevent air leakage after the water permeable plate 6 is sealed.

[0023] In an embodiment of the present application, preferably, the water outlet 8 is located between the two water permeable plates 6. When the piston valve 4 slides and the water intake of the water storage device 3 is insufficient, the water volume between the water permeable plates 6 can meet the water outlet requirement.

[0024] In an embodiment of the present application, preferably, the spraying assembly 9 includes a water pump 91. The water pump 91 is connected to the water outlet 8 through a pipeline. A water intake 92 is connected to the pipeline of the water pump 91. A valve 93 is connected to the water intake 92. A sprinkler 94 and a flushing nozzle 95 are connected to the pipeline of the water pump 91. A flow regulating valve 96 is fixedly connected to the pipeline connecting the sprinkler 94 and the flushing nozzle 95 to the water pump 91, which is used for the function conversion of water intake and outlet and the regulation of the watering volume to meet the requirements under different working conditions. It should be noted that the specific structures of the water pump 91, the water intake 92, the valve 93, the sprinkler 94, the flushing nozzle 95, and the flow regulating valve 96 all adopt existing technologies, and the specific structures will not be elaborated here.

[0025] In an embodiment of the present application, preferably, an inspection opening 10 is fixedly connected to the top of the water tank 2 for inspecting the water tank 2, the water storage device 3 and the piston valve 4 inside the water tank 2.

[0026] In summary, for the sprinkler truck with adjustable water output in the above embodiments of the present utility model, specifically, when the sprinkler truck goes uphill, the water in the water tank 2 flows towards the rear of the vehicle under the action of gravity. The piston valve 4 in the water storage device 3 slides towards the rear of the vehicle under the action of the gravity and inertia of the counterweight plate 41 and the water flow. At this time, the counterweight plate 41 at the front of the vehicle drives the rubber pad to move to the position of the water permeable plate 5 at the same end to close the water permeable plate 5, while the piston valve 4 at the rear end of the vehicle slides away from the water permeable plate 6, so that the water in the water tank 2 enters the water storage device 3 through the water inlet hole 7 and reaches the water outlet 8 through the water permeable plate 6. Since the air cannot enter the water storage device 3 because the water permeable plate 6 at the front end of the vehicle is closed, the spraying assembly 9 can continuously draw out water from the water outlet 8. When the sprinkler truck goes downhill, the movement of the piston valve 4 is opposite and consistent with the water flow collection direction, ensuring the water supply at the water outlet when the water in the sprinkler truck collects towards one end and avoiding the interruption of the watering work.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not deviate from the spirit and scope of the technical solutions of the present utility model in each embodiment.
