[0035] Fixing support: pump-out pipe support 12 made of channel steel is used to support pump-out pipe 8, to ensure its stability.Self-flow sprinkling pipe 18 is fixed on vehicle frame 26 through U-shaped fixing plate 17 and shockproof rubber pad 24.U-shaped fixing plate 17 is connected with vehicle frame 26 by bolt, and shockproof rubber pad 24 is arranged between the two, which can ensure the stable installation of self-flow sprinkling pipe 18, and also can play a shock-absorbing role, to reduce the influence of vibration in vehicle driving process on pipeline.

[0036] The water inlet pipe of centrifugal pump 3 is connected with water outlet at the bottom of tank body 25 by flange structure, and the connection is firm and sealed well, to ensure smooth water flow.

[0037] Both ends and middle part of the self-flowing sprinkling pipe 18 are blocked by blind plates 23, and the blind plates 23 and the self-flowing sprinkling pipe 18 are sealed by 4" round flange pads to prevent water leakage and ensure that water flows out of the self-flowing sprinkling pipe in the designed direction.

[0041] Usage process: I. Power source and water pumping

[0042] The power core of the entire water tank spraying system is the hydraulic drive unit. After the hydraulic motor 1 starts, it generates rotary power, and its output end is flexibly connected to the input end of the centrifugal pump 3 through the plum blossom elastic coupling 2. This flexible connection method can effectively transmit power and buffer the vibration caused by power transmission, protecting the equipment components. The power of the hydraulic motor 1 is smoothly transmitted to the centrifugal pump 3 through the plum blossom elastic coupling 2, driving the centrifugal pump 3 to start operating.

[0043] During the operation of the centrifugal pump 3, a negative pressure is formed at its water inlet pipe. Since the water inlet pipe of the centrifugal pump 3 is firmly and tightly connected to the water outlet of the tank body 25 through a flange structure, under the action of negative pressure, the drinking water stored in the tank body 25 is sucked into the centrifugal pump 3 along the pump-in pipe 19. The pump-in pipe 19 and the pump-out pipe 22 are sealed and fastened by the PVC transparent steel wire pipe 20 and the strong throat clamp 21, ensuring that no leakage occurs during water suction and ensuring that the water flow enters the centrifugal pump 3 stably.

[0044] II. Spraying operation of the upper nozzle assembly

[0045] The water sucked by the centrifugal pump 3 is pumped out at high speed by the pump-out pipe 8 under the pressure of the centrifugal pump 3. The pump-out pipe 8 is connected with at least three spray heads 5 in the upper spray head assembly through the PVC transparent steel wire pipe 20. These spray heads 5 are controlled by air pressure. When the water flow with certain pressure reaches the spray head 5, the air pressure control structure inside the spray head 5 adjusts the water flow. Under the joint action of air pressure and water pressure, the water flow is sprayed out from the spray head 5 at a certain angle and pressure. For example, through the design of the internal structure of the spray head 5, the water flow can be sprayed out in different forms such as fan-shaped or columnar, so as to realize efficient spraying of a certain area and meet the operation requirements such as washing of dust at high places in road cleaning, watering of the top of plants in greening irrigation, etc.

[0046] III. Working mechanism of the lower self-flowing sprinkling pipe

[0047] The lower self-flowing sprinkling pipe 18 is located below the tail of the tank body 25 on both sides, one on each side. The self-flowing sprinkling pipe 18 controls the water flow through the stainless steel pneumatic butterfly valve 13. When self-flowing spraying operation is needed, the stainless steel pneumatic butterfly valve 13 is opened. At this time, the water in the tank body 25 flows to the self-flowing sprinkling pipe 18 under the action of gravity. The surface of the self-flowing sprinkling pipe 18 is provided with three rows of φ10mm small holes distributed in a staggered manner. The spraying directions of the small holes are directly below, 45° obliquely backward and directly backward, respectively. Since the water level in the tank is higher than that of the self-flowing sprinkling pipe 18, the water flows out from these small holes under the driving of gravitational potential energy. The small holes directly below can directly wash the ground, the small holes 45° obliquely backward can spray water to a certain distance behind and on both sides of the vehicle, and the small holes directly backward are mainly used for sprinkling water to the area directly behind the vehicle. This multi-angle small hole design realizes large-area self-flowing spraying and is suitable for road dust reduction, road surface moisturizing and other scenes.

[0048] IV. Connection of pipeline and control of water flow distribution

The stainless steel manual butterfly valve 10 is installed at the right outlet of the pump-out pipe 8, and the outlet end thereof is inclined downward by 60°. The operator can manually adjust the opening and closing degree of the stainless steel manual butterfly valve 10 according to the actual operation requirements, so as to control the flow and flow direction of the water flow. When other equipment or pipelines need to be connected externally, the outlet end of the manual butterfly valve 10 is connected with the aluminum alloy flange male end 11 through bolts, so as to conveniently and quickly realize the butt joint with other equipment.

[0050] In addition, the two ends and the middle of the self-flowing sprinkler pipe 18 are blocked by blind plates 23, and the blind plates 23 and the self-flowing sprinkler pipe 18 are sealed by 4" round flange pads to ensure that water can only flow out of the small holes on the surface, and high-efficiency spraying is achieved according to the designed direction. At the same time, 3" round flange pad two 6, shockproof rubber pads 24, and sealing rubber pads at the pipe connection are made of food-grade materials, which not only ensures the sealing of the connection to prevent water leakage, but more importantly, ensures that the drinking water is not contaminated during transportation and always meets the health standards.

[0054] Lower self-flowing sprinkler pipe: two self-flowing sprinkler pipes 18 are arranged on both sides of the lower tail of the tank 25, and φ10mm small holes with three rows of staggered distribution and different spraying directions (directly below, 45° oblique rear, and directly rear) are arranged on the surface. The gravity potential is used to realize self-flowing spraying in a large area. The small holes directly below directly wash the ground, the small holes with 45° oblique rear cover the area behind the vehicle and on both sides, and the small holes directly rear spray water directly behind the vehicle, which is suitable for road dust reduction, road moisture retention, etc., and improves the coverage and efficiency of water spraying operation.

[0055] Precise water flow distribution and control: in the pipe assembly, the stainless steel manual butterfly valve 10 is installed at the right outlet of the pump outlet pipe 8, the outlet end is inclined downward by 60°, and the operator can flexibly manually adjust the opening and closing degree according to the actual operation demand, and accurately control the flow and flow direction of the water flow. At the same time, the outlet end of the manual butterfly valve 10 is connected with the aluminum alloy flange male end 11 through bolts, which is convenient for quick docking with other equipment or external pipelines to meet the water flow distribution demand in different operation scenes.

[0056] Good sealing and health protection: the system uses sealing design in many places, such as the two ends and the middle part of the self-flowing sprinkler pipe 18 are sealed by blind plates 23, and the water flow is ensured to flow out of the small hole in the designed direction through 4" round flange gasket sealing; the connection between the spray head 5 and the pump outlet pipe 8 adopts 3" round flange gasket two 6 sealing; the shockproof rubber pad 24 and the sealing rubber pad at all pipeline connections are made of food-grade materials.
