[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] The following is combined with Figures 1 to 3 This invention describes an automatic spray truck washing trough for construction sites.

[0038] like Figures 1 to 3 As shown in the figure, the automatic construction site washing spray truck washing tank provided in this embodiment of the utility model includes a water storage tank 1, a washing tank, a pressure pump 5 and a control device.

[0039] Specifically, the water storage tank 1 is used to store water, and the pressure pump 5 is located between the washing tank and the water storage tank 1. The pressure pump 5 is used to pressurize the water in the water storage tank 1 and pump it to the washing tank, which washes the vehicle.

[0040] The flushing tank includes a pair of baffles 2, a nozzle 4, and a height detection element. A flushing channel 3 is formed between the pair of baffles 2 for vehicles to pass through.

[0041] Sprinklers 4 are mounted on baffles 2, and multiple sets of sprinklers 4 are mounted on each baffle 2. These sets of sprinklers 4 are connected in parallel, and each set of sprinklers 4 corresponds to at least one control valve. Individual control of any set of sprinklers 4 can be achieved through each control valve. All sets of sprinklers 4 can spray water, all can stop spraying water, or only a portion of them can spray water.

[0042] Multiple sets of nozzles 4 are spaced apart along the height direction of the baffle 2, and each set of nozzles 4 is spaced apart along the length direction of the baffle 2. A height detection element is used to detect the height of the vehicle within the washing channel 3. The pressure pump 5, control valves, and height detection element are all electrically connected to a control device, which controls the opening and closing states of each control valve and the output pressure of the pressure pump 5 according to the vehicle's height.

[0043] Specifically, the output pressure of the booster pump 5 can be controlled by controlling the power of the booster pump 5.

[0044] This setup allows for the control of water spraying from nozzles 4 within a certain height range based on the vehicle's height. Nozzles 4 above the vehicle's height will stop spraying, reducing water waste and ensuring water pressure at the nozzles 4. Combined with the control of the output water pressure of the booster pump 5, this effectively ensures water pressure at the nozzles 4, improves the spraying and rinsing effect, and solves the problem of unreliable water pressure in construction site car wash troughs in related technologies.

[0045] In some embodiments, each group of nozzles 4 may correspond to only one control valve, which can simultaneously control the water supply to each nozzle 4 in that group.

[0046] In other embodiments, each group of nozzles 4 may correspond to at least two control valves, with several nozzles 4 in each group corresponding to one control valve, allowing for separate control of the group of nozzles 4. In this embodiment, a position detection element can be installed on the baffle 2 to detect the vehicle's position within the washing channel 3. The position detection element is electrically connected to the control device, which can also control the nozzles 4 at the corresponding positions to spray water based on the vehicle's position within the washing channel 3, while nozzles 4 located outside the specified position range will stop spraying water. This arrangement further reduces water waste and ensures water pressure at the spraying nozzles 4.

[0047] In this embodiment of the invention, each set of nozzles 4 is connected by a connecting pipe, and the rinsing tank also includes a pressure detection element, which is used to detect the water pressure in the connecting pipe.

[0048] The pressure sensing element is electrically connected to the control device, which can also control the opening degree of the control valve and the output pressure of the booster pump 5 according to the water pressure in the connecting pipeline, so as to realize the water pressure control of each group of nozzles 4.

[0049] The control valve mentioned above can be a flow regulating valve.

[0050] In this embodiment, the water storage tank 1 includes a water storage tank body 6 and a float valve.

[0051] The main body of the water storage tank 6 has a water inlet 7, an overflow outlet 8, and a water outlet. The water inlet 7 is used to connect the water supply pipe, and the water outlet is used to connect the water outlet pipe.

[0052] The water supply pipe is used to supply water to the main body 6 of the water storage tank. The float valve is set at the water supply port 7. The float valve is used to control the water supply port 7 to close when the water level in the main body 6 of the water storage tank reaches the first preset position, and to control the water supply port 7 to open when the water level in the main body 6 of the water storage tank reaches the second preset position. The height of the first preset position is greater than the height of the second preset position.

[0053] This configuration allows the water level inside the main body 6 of the reservoir to be controlled within a certain range, ensuring that the water volume inside the main body 6 is sufficient.

[0054] Overflow outlet 8 is used to connect to overflow pipe. Overflow outlet 8 is located at a higher position on the main body of water storage tank 6. When the water level in water storage tank 1 reaches the position of overflow outlet 8, overflow pipe is used to allow water in water storage tank 1 to overflow outward, so as to avoid excessive pressure in water storage tank 1.

[0055] In this embodiment of the invention, in each set of nozzles 4 on each baffle 2, any two adjacent sets of nozzles 4 are staggered. This arrangement enables uniform spraying and coverage, reduces blind spots, and improves the spraying and washing effect on vehicles.

[0056] In this embodiment, the nozzle 4 can be, but is not limited to, a spiral nozzle. Adjacent nozzles 4 can cooperate to form cross-flow water, which can impact the vehicle surface from multiple angles. Through the interaction of water flows in different directions, stubborn dirt attached to the vehicle surface can be more effectively removed, enhancing the cleaning effect. Moreover, the spiral nozzle can produce very fine and uniform water droplets, ensuring a more uniform distribution of moisture in the coverage area, and also has the advantages of high efficiency, energy saving, and anti-clogging.

[0057] In this embodiment of the utility model, the water outlet pipe includes a main water outlet pipe 10, a first branch pipe 11, a second branch pipe 12, and a third branch pipe 13. The first end of the main water outlet pipe 10 is connected to the water storage tank body 6, and the first ends of the first branch pipe 11, the second branch pipe 12, and the third branch pipe 13 are all connected to the second end of the main water outlet pipe 10.

[0058] The booster pump 5 is installed on the main water outlet pipe 10. A main valve can be installed on the main water outlet pipe 10 to control the on / off state of the main water outlet pipe 10.

[0059] A first valve is installed on the first branch pipe 11, which is used to control the on / off state of the first branch pipe 11. The second end of the first branch pipe 11 is used to connect to each group of spray heads 4. When the first valve is in the open state, the pressurization pump 5 operates, which can pressurize and pump the water in the water storage tank 1 to the flushing tank.

[0060] A second valve is installed on the second branch pipe 12, which is used to control the on / off state of the second branch pipe 12. The second end of the second branch pipe 12 is used to connect to fire extinguishing equipment. When the second valve is in the open state, the booster pump 5 operates, which can boost the water in the water storage tank 1 and pump it to the fire extinguishing equipment to supply water to the fire extinguishing equipment.

[0061] A third valve is installed on the third branch pipe 13, which is used to control the on / off state of the third branch pipe 13. The second end of the third branch pipe 13 is used to connect to the sanitary equipment in the construction site living area. When the third valve is in the open state, the booster pump 5 operates, which can boost the water in the water storage tank 1 to the sanitary equipment in the construction site living area, thus supplying water to the sanitary equipment in the construction site living area.

[0062] With this configuration, water storage tank 1 can supply water to the flushing tank, as well as to fire-fighting equipment and sanitary facilities in the construction site's living area. This enables the water storage tank 1 to be shared, effectively integrates resources, reduces costs, and improves emergency response capabilities and management efficiency.

[0063] The fire extinguishing equipment is located in the tower, which has a multi-story structure, with fire extinguishing equipment installed on each floor. The second end of the second branch pipe 12 is connected to multiple branch pipes, one for each floor. Each branch pipe has an internal pressure-reducing orifice plate to lower the water pressure within it.

[0064] The orifice diameter of the pressure-reducing orifice plate is determined based on the floor where the fire extinguishing equipment is located. On floors below 26 stories, pressure-reducing orifice plates are installed on each floor to accommodate the water pressure requirements of different floors. The orifice diameter of the pressure-reducing orifice plate is 15-30 mm; the orifice diameter is relatively smaller on lower floors and relatively larger on higher floors.

[0065] In this embodiment of the invention, the second end of the first branch pipe 11 is connected to two branch pipes. One branch pipe connects to one end of each connecting pipe, and the other branch pipe connects to the other end of each connecting pipe. This arrangement forms a loop with the two branch pipes and the connecting pipes. Water from the main outlet pipe 10 enters the two branch pipes, and water from the two branch pipes enters the connecting pipe from both ends, flowing from both ends towards the center. Simultaneous water supply from both ends of the connecting pipe ensures a uniform pressure distribution within it, resulting in more consistent pressure across the nozzles and guaranteeing uniform water output from each group of nozzles. Furthermore, this improves water supply efficiency and reduces the impact of localized resistance within the connecting pipe.

[0066] In this embodiment, the rinsing tank also includes brackets 14. Each baffle 2 is provided with multiple sets of brackets 14, which are spaced apart along the length of the baffle 2. The brackets 14 are used to support the connecting pipes corresponding to each set of nozzles 4. This arrangement can improve the stability of the connecting pipes.

[0067] In this embodiment, the washing tank also includes speed bumps 9, which are disposed on the bottom wall of the washing channel 3. Multiple speed bumps 9 are provided, spaced apart along the length of the baffle 2. This arrangement forces vehicles to slow down as they pass, increasing the washing spray time and improving cleaning efficiency.

[0068] It should be noted that a drainage trough is also provided on the bottom wall of the washing channel 3 between the pair of baffles 2. After the water sprayed by the nozzles 4 washes the vehicle, it will be discharged through the drainage trough. A recycling pipeline is provided between the drainage trough and the water storage tank 1, and a sewage treatment device is installed on the recycling pipeline. The sewage in the drainage trough can be treated by the sewage treatment device and recycled back to the water storage tank 1 for reuse.

[0069] In a specific embodiment, the length of the water storage tank 1 can be 2 meters, the width can be 2 meters, and the height can be 1.5 meters. The diameter of the water supply pipe can be 50 mm, and the diameter of the overflow pipe can be 100 mm. The distance between a pair of baffles 2 is 3.5 meters, the length of the baffles 2 is 8 meters, and the height of the baffles 2 is 1.5 meters. Five speed bumps 9 are set between a pair of baffles 2, the height of the speed bumps 9 is 0.08 meters, and the length of the speed bumps 9 along the length of the baffles 2 is 0.2 meters. Three sets of nozzles 4 are set on each baffle 2, wherein the distance between the first set of nozzles 4 and the bottom wall of the flushing channel 3 is 0.2 meters, the distance between the second set of nozzles 4 and the bottom wall of the flushing channel 3 is 0.75 meters, and the distance between the third set of nozzles 4 and the bottom wall of the flushing channel 3 is 1.3 meters. The nozzles 4 are spiral nozzles with a nozzle diameter of 7.5 mm, and the distance between two adjacent nozzles 4 in each set of nozzles 4 is 220 mm. The booster pump 5 has a model number of XBD18 / 10-80G / 9, a head of 180m, a flow rate of 10L / s, a motor power of 37kW, and supports manual control, automatic control, and frequency conversion control.

[0070] The main water outlet pipe 10 is made of hot-dip galvanized steel pipe, and the connecting pipes are made of seamless steel pipe. The distance between two adjacent brackets 14 used to support the connecting pipes is 1.98 meters.

[0071] In summary, through extensive testing, the automatic construction site washing spray vehicle washing trough provided by this utility model embodiment has improved the washing efficiency by 40%, with a single vehicle washing time of less than or equal to two minutes; it saves 30% of water by reducing waste through a circulating water system and precise spraying; and it can adapt to the water supply needs of high-rise buildings with water pressure fluctuations of less than or equal to 5%.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
