Description

Technical Field

[0001] This utility model relates to the technical field of road cleaning devices, and in particular to a high-pressure washing device for sprinkler trucks. Background Technology

[0002] Water trucks play a crucial role in urban road cleaning and maintenance. Traditional water truck washing systems primarily function to simply spray water on roads to reduce dust. Their operation is typically carried out routinely on main urban roads, secondary roads, and some residential roads. However, with continuously improving urban environmental standards, the requirements for road cleanliness are becoming increasingly stringent. It's not enough to simply remove surface dust; effective cleaning of oil stains and stubborn dirt is also necessary. This makes traditional systems with only basic watering capabilities insufficient to meet the growing cleaning demands. For example, in areas with heavy oil pollution, such as restaurant streets, ordinary water trucks cannot thoroughly clean the ground, leaving residual dirt that affects the city's appearance and poses safety hazards.

[0003] Most traditional sprinkler trucks use a relatively simple water pump structure for their washing system. The pump draws water from a tank and sprays it through nozzles at a fixed angle, relying on the water's own weight and initial pressure to impact the road surface. The nozzles are generally fixed to the bottom or side of the sprinkler truck. The water pump is usually a single-stage impeller structure, using the centrifugal force generated by the impeller's rotation to deliver water.

[0004] Existing technologies have several problems in practical applications. First, in terms of pressure, single-stage impeller water pumps cannot generate enough pressure to clean stubborn stains. Taking roads around industrial plants as an example, vehicles frequently transport goods, and the road surface often has a mixture of oil and mud stains. Single-stage water pumps do not provide sufficient pressure to effectively remove these stains. Therefore, a high-pressure washing device for sprinkler trucks is provided to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-pressure washing device for sprinkler trucks, which aims to improve the problem that the water pressure is too low when sprinkler trucks wash the road surface, making it difficult to effectively clean the road surface.

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

[0007] A high-pressure washing device for a sprinkler truck includes a hanger, a water pump, and a pressurizing mechanism. The water pump is installed at the bottom of the hanger. The pressurizing mechanism includes a pressurizing component and an auxiliary component. The auxiliary component includes multiple impellers installed inside the water pump. An inlet pipe is provided on the outside of the water pump, and an outlet pipe is provided at one end of the water pump. One-way valves are provided at the connections of the inlet pipe and the outlet pipe to the water pump.

[0008] As a further description of the above technical solution:

[0009] The pressurizing component includes a motor, which is mounted on the outside of the hanger. A disc is fixedly connected to the output end of the motor, and a lever is fixedly connected to the outside of the disc.

[0010] As a further description of the above technical solution:

[0011] The bottom of the hanger is fixedly connected to two hanging rods, and a cross frame is slidably connected to the inner side of the two hanging rods. The outer side of the lever is slidably connected to the inner side of the cross frame.

[0012] As a further description of the above technical solution:

[0013] One end of the cross frame penetrates the inner wall of the water pump and is fixedly connected to a piston, and the outer side of the piston is slidably connected to the inner wall of the water pump.

[0014] As a further description of the above technical solution:

[0015] The water pump is equipped with a flushing mechanism, which includes a support frame. One end of the support frame is fixedly connected to the outside of the water pump, and the other end of the support frame is fixedly connected to a mounting bracket.

[0016] As a further description of the above technical solution:

[0017] An electric telescopic rod is installed on the inner side of the mounting frame. A movable block is fixedly connected to the output end of the electric telescopic rod. Two sets of rotating rods are rotatably connected to the outer side of the movable block, with two rotating rods in each set.

[0018] As a further description of the above technical solution:

[0019] Two sets of positioning rods are fixedly connected to the outer side of the mounting bracket. Each set of positioning rods consists of two rods. A nozzle is rotatably connected to the adjacent side of each set of positioning rods. The adjacent side of each set of rotating rods is rotatably connected to the outer side of the corresponding nozzle.

[0020] As a further description of the above technical solution:

[0021] One end of the nozzle is fixedly connected to a guide tube, and one end of the guide tube is fixedly connected to the water outlet pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the device is securely suspended at the bottom of the sprinkler truck, ensuring overall stability and laying the foundation for subsequent operations. At the same time, the water inlet pipe and water tank are tightly connected to ensure a smooth water supply, avoid problems such as leakage, and improve work efficiency. The dual pressurization mechanism inside the water pump uses the reciprocating motion of the piston to create negative pressure for water suction and the rotation of the impeller to give the water kinetic energy. The synergistic effect greatly increases the water pressure, enabling the road surface to be washed efficiently with powerful force, far exceeding the effect of traditional water pumps.

[0024] 2. In this utility model, the flushing range can be flexibly adjusted through the flushing mechanism. The electric telescopic rod extends and retracts, driving the movable block to move, which in turn drives the rotating rod to rotate the spray pipe around the positioning rod. This flexible adjustment method can adjust the spray pipe swing angle by controlling the extension and retraction frequency and stroke of the electric telescopic rod according to different road conditions, so as to achieve efficient flushing of a wider road surface area by high-pressure water jet. Compared with traditional sprinkler trucks, it greatly enhances the cleaning ability of the road surface. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figure 1 - Figure 5This utility model provides an embodiment of a high-pressure washing device for a sprinkler truck, comprising a hanger 1, a water pump 2, and a pressurizing mechanism. The water pump 2 is installed at the bottom of the hanger 1. The pressurizing mechanism includes a pressurizing component and an auxiliary component. The auxiliary component includes multiple impellers 9, which are installed inside the water pump 2. When the motor 3 is turned on, its output shaft drives the disc 4 to perform a circular motion, and the lever 6 rotates accordingly. Because the outer side of the lever 6 is slidably connected to the inner side of the cross frame 7, as the disc 4 continues to rotate, the lever 6 will periodically push the cross frame 7. When the cross frame 7 is pushed by the lever 6, it will make a linear reciprocating motion along the inner side of the two hanging rods 5. One end of the cross frame 7 is fixedly connected to the piston 8, so the reciprocating movement of the cross frame 7 will synchronously drive the piston 8 to reciprocate within the inner wall of the water pump 2. When the piston 8 moves outward, the corresponding space inside the water pump 2 increases, the pressure decreases, and a negative pressure environment is formed. At this time, the one-way valve at the inlet pipe 10 opens, and the water in the tank is drawn into the water pump 2 through the inlet pipe 10 under atmospheric pressure. When the piston 8 moves inward, the space inside the water pump 2 decreases, the pressure increases, the one-way valve at the inlet pipe 10 closes to prevent water backflow, and at the same time, the one-way valve at the outlet pipe 11 opens, and water is squeezed out of the water pump 2. Meanwhile, multiple impellers 9 installed inside the water pump 2 rotate at high speed when the water pump 2 is running. The rotation of the impellers 9 causes the water to be thrown from the center of the impeller 9 to the edge of the impeller 9 under the action of centrifugal force. In this process, the water gains additional kinetic energy, further increasing the water pressure. The negative pressure generated by the reciprocating motion of the piston 8 and the kinetic energy given to the water by the rotation of the impeller 9 work together to achieve a double pressurization of the water, greatly increasing the pressure of the water flowing out of the outlet pipe 11. An inlet pipe 10 is provided on the outside of the water pump 2, and an outlet pipe 11 is provided at one end of the water pump 2. One-way valves are provided at the connection points of the inlet pipe 10 and the outlet pipe 11 with the water pump 2. The pressurization assembly includes a motor 3, which is mounted on the outside of the hanger 1. A disc 4 is fixedly connected to the output end of the motor 3, and a lever 6 is fixedly connected to the outside of the disc 4. Two hanging rods 5 are fixedly connected to the bottom of the hanger 1, and a cross frame 7 is slidably connected to the inner side of the two hanging rods 5. The outer side of the lever 6 is slidably connected to the inner side of the cross frame 7. One end of the cross frame 7 penetrates the inner wall of the water pump 2 and is fixedly connected to a piston 8. The outer side of the piston 8 is slidably connected to the inner wall of the water pump 2. A flushing mechanism is installed on the outside of the water pump 2. The flushing mechanism includes a support frame 12, one end of which is fixedly connected to the outside of the water pump 2, and the other end of which is fixedly connected to a mounting frame 13. An electric telescopic rod 14 is installed inside the mounting frame 13, and its output end is fixedly connected to a movable block 15. When the electric telescopic rod 14 is started, it extends or shortens according to its extension command. When the electric telescopic rod 14 extends, it pushes the movable block 15 to move along the guide direction of the mounting frame 13, and the two sets of rotating rods 18 rotatably connected to the outside of the movable block 15 move accordingly.Each set of rotating rods 18 consists of two rods, with one end of the rotating rod 18 rotatably connected to the movable block 15 and the other end rotatably connected to the outer side of the corresponding nozzle 17. Due to the rotatable connection characteristics of the rotating rod 18, as the movable block 15 moves, the rotating rod 18 will rotate around the connection point with the movable block 15 and the nozzle 17, thereby driving the nozzle 17 to rotate around the positioning rod 16. Positioning rods 16 are fixed to the outside of the mounting frame 13. Each set of positioning rods 16 has two rods. The nozzle 17 is rotatably connected to the adjacent sides of the two positioning rods 16, serving to support and limit the rotation direction of the nozzle 17. When the electric telescopic rod 14 shortens, the movable block 15 moves in the opposite direction, and the rotating rod 18 drives the nozzle 17 to rotate in the opposite direction. By controlling the extension frequency and stroke of the electric telescopic rod 14, the swing angle of the nozzle 17 can be flexibly adjusted, allowing the high-pressure water jet sprayed from the nozzle 17 to cover a wider area of ​​the road surface, efficiently washing different locations. Compared to traditional water trucks, this greatly improves the road washing effect. The electric telescopic rod 14 is installed on the inner side of the mounting frame 13. A movable block 15 is fixedly connected to the output end of rod 14. Two sets of rotating rods 18 are rotatably connected to the outer side of the movable block 15. There are two rotating rods 18 in each set. Two sets of positioning rods 16 are fixedly connected to the outer side of the mounting bracket 13. There are two positioning rods 16 in each set. A nozzle 17 is rotatably connected to the adjacent side of each set of positioning rods 16. The adjacent side of each set of rotating rods 18 is rotatably connected to the outer side of the corresponding nozzle 17. A conduit 19 is fixedly connected to one end of the nozzle 17. One end of the conduit 19 is fixedly connected to the water outlet pipe 11 to ensure that the high-pressure water after double pressurization can be smoothly delivered from the water outlet pipe 11 through the conduit 19 to the nozzle 17, and finally sprayed out in the form of a high-pressure water jet for road washing operations.

[0034] Specifically, firstly, the hanger 1 is securely suspended at the bottom of the sprinkler truck. This operation ensures that the entire high-pressure flushing device can move stably with the sprinkler truck, providing a reliable support foundation for subsequent road washing operations. If the hanger 1 is not securely installed, the device may shake, shift, or even fall off during the sprinkler truck's operation, affecting normal flushing work. Next, the inlet pipe 10 is connected to the sprinkler truck's water tank using a pipe. In this way, the water in the water tank can smoothly enter the water pump 2 through the inlet pipe 10, providing a water source for subsequent pressurization and flushing operations. If the connection is not tight or the pipe is damaged, it may cause water leakage, which will not only waste water resources, but also affect the normal water intake of water pump 2, thereby reducing the working efficiency of the entire device. When the sprinkler truck is in motion, the motor 3 is started. The motor 3, as the power source, starts to rotate and drives the disc 4 to perform circular motion. Since the lever 6 is fixedly connected to the outside of the disc 4, the rotation of the disc 4 will drive the lever 6 to perform circular motion. The outside of the lever 6 is slidably connected to the inside of the cross frame 7, and the cross frame 7 is slidably connected to the inside of the two hanging rods 5. Therefore, the circular motion of the lever 6 will be converted into the reciprocating linear movement of the cross frame 7 along the direction of the hanging rods 5. One end of the cross frame 7 passes through the water pump. The inner wall of pump 2 is fixedly connected to piston 8. Therefore, the reciprocating movement of cross frame 7 causes piston 8 to slide reciprocally within the inner wall of pump 2. When piston 8 moves outward, the corresponding space inside pump 2 increases, the pressure decreases, creating a negative pressure environment. At this time, the one-way valve at inlet pipe 10 opens, and under atmospheric pressure, water from the tank is smoothly drawn into pump 2 through inlet pipe 10. When piston 8 moves inward, the internal space of pump 2 decreases, the pressure increases, and the one-way valve at inlet pipe 10 closes to prevent backflow. Simultaneously, the one-way valve at outlet pipe 11 opens, and water is squeezed out of pump 2. At the same time, multiple impellers 9 installed inside pump 2 rotate at high speed under the drive of motor 3 during pump 2 operation. The rotation of impellers 9 causes water to be thrown from the center of impeller 9 to the edge of impeller 9 under centrifugal force. During this process, the water gains additional kinetic energy, further increasing its pressure. The negative pressure generated by the reciprocating motion of piston 8 and the kinetic energy imparted to the water by the rotation of impeller 9 work together to achieve a double pressurization of the water. This results in a significant increase in the pressure of the water sprayed from the outlet pipe 11 compared to a traditional pump, allowing it to be sprayed out at higher pressure and speed, providing powerful momentum for subsequent efficient road washing. Furthermore, to achieve washing of a large area of ​​the road surface, the electric telescopic rod 14 can be activated for extension and retraction. The electric telescopic rod 14 is installed inside the mounting frame 13, and its output end is fixedly connected to the movable block 15. When the electric telescopic rod 14 extends, it pushes the movable block 15 to move along the guide direction of the mounting frame 13.Two sets of rotating rods 18 are rotatably connected to the outer side of the movable block 15. Each set of rotating rods 18 consists of two rods, with one end of the rotating rod 18 rotatably connected to the movable block 15 and the other end rotatably connected to the outer side of the corresponding nozzle 17. Due to the rotatable connection characteristics of the rotating rods 18, as the movable block 15 moves, the rotating rods 18 rotate around the connection point between the movable block 15 and the nozzle 17, thereby driving the nozzle 17 to rotate around the positioning rod 16. The positioning rods 16 are fixed to the outer side of the mounting bracket 13. There are two positioning rods 16 in each set. The nozzle 17 is rotatably connected to the adjacent sides of the two positioning rods 16, serving to support and limit the rotation direction of the nozzle 17. When the electric telescopic rod 14 is shortened, the movable block 15 moves in the opposite direction, and the rotating rods 18 drive the nozzle 17 to rotate in the opposite direction. By controlling the extension frequency and stroke of the electric telescopic rod 14, we can flexibly adjust the swing angle of the nozzle 17. In this way, the high-pressure water jet sprayed from the nozzle 17 can cover a wider area of ​​the road surface, efficiently washing the road surface in different locations. Compared to traditional water trucks, this adjustable washing range allows the device to have a stronger washing effect on the road surface, and can more comprehensively and efficiently clean dust, stains and other impurities on the road surface.

[0035] Working principle: First, the hanger 1 is suspended at the bottom of the sprinkler truck. The water inlet pipe 10 is connected to the water tank of the sprinkler truck. When the sprinkler truck is in motion, the motor 3 drives the disc 4 to rotate, which in turn causes the lever 6 to move the cross frame 7 back and forth, thereby driving the piston 8 to move back and forth. This generates negative pressure inside the water pump 2 when the pump is running, and then transmits energy to multiple impellers 9. Under this double pressurization effect, the pressure of the water sprayed from the outlet pipe 11 increases dramatically. In addition, the electric telescopic rod 14 can be activated to extend and retract, which in turn drives the rotating rod 18 to rotate, causing one end of the two spray pipes 17 to swing up and down. This allows the high-pressure water jets sprayed from the spray pipes 17 to wash a large area of ​​the road surface, which has a stronger washing effect on the road surface than traditional sprinkler trucks.
