Description

Technical Field

[0001] The utility model relates to the technical field of road surface water treatment, in particular to a mobile vehicle for automatic water accumulation treatment. Background Art

[0002] Some areas of the garden are low-lying, and water easily accumulates in these areas after rain. Traditionally, manual treatment is required, which is inefficient. To this end, the industry has proposed automatic water-handling devices. For example, patent document CN107335280 A discloses a road surface water absorption filter. The machine is equipped with a water collection device, a filter device is provided at the water inlet of the water collection device, and a water suction device connected to the outside world is also provided. The water suction port of the water suction device is located outside the machine, and the water outlet is connected to the filter device. The road surface water is sucked into the filter device for filtration before flowing into the water collection device; a drain port is provided at the bottom of the water collection device; and the road surface water absorption filter is provided with universal wheels at the bottom for easy manual movement. Although the technical solution provided in this patent document achieves automatic treatment of road surface water and saves labor, it only provides a filter device at the water inlet of the water collection device. Water with impurities only reaches the filter device after passing through the water suction device. Impurities in the water may remain in the water suction device, which can easily cause the water suction device to be blocked by impurities over time. Summary of the Invention

[0014] The present invention is further described in detail below in conjunction with specific embodiments.

[0015] Automatic water treatment mobile vehicle Figure 1 As shown, a water tank 1 is provided in the vehicle body 100 (see Figure 2 ).like Figure 2 As shown, a filter screen 2 is provided at the water inlet of the water tank 1. Figure 1 As shown, the vehicle is provided with a water suction device 3, which includes a water pump 31 (see Figure 2), a suction pipe 32 connected to the water inlet of the water pump 31, and a water outlet pipe 33 connected to the water outlet of the water pump 31. The outlet 330 of the outlet pipe 33 is connected to the water inlet of the water tank 1. The suction port 320 of the suction pipe 32 is located outside the vehicle body and faces downward. The suction pipe 32 is equipped with a telescopic pipe section 322 at the suction port 320. The user can operate the telescopic pipe section 322 to extend and retract, allowing the suction port 320 to move vertically closer to the ground at different terrains, facilitating the treatment of accumulated water in low-lying areas.

[0016] like Figure 1 As shown, the suction pipe 32 is provided with a vertical filter section 321, and the suction port 320 of the suction pipe 32 is located at the lower end of the filter section 321. To treat road surface water, the user activates the water pump 31 to draw water. Under the action of the water pump 31, the road surface water flows upward from the suction port 320, through the filter section 321, and is filtered. It then flows through the water pump 31 and the outlet pipe 33 into the top of the water tank 1. It is then filtered by the filter 2 before falling into the water tank 1. Once all the road surface water has been absorbed, the user turns off the water pump 31 to stop drawing water. The bottom of the water tank 1 is connected to the outside of the vehicle via the drain pipe 11. A valve 12 is provided on the drain pipe 11 to control the opening and closing of the drain port. The user can access the water stored in the water tank 1 for irrigation or other uses. Specifically, by operating the valve 12 to open the drain port of the drain pipe 11, the water stored in the water tank 1 flows out for the user to use. The automatic water treatment mobile vehicle provided by the present invention is provided with a filter pipe section 321 in the water suction pipe 32 to filter the sucked water, so that most impurities in the water will not enter the water suction device 3, which can prevent the water suction device 3 from being blocked by impurities in the water.

[0017] Because road surface water often contains impurities, impurities will remain at the lower end of the filter pipe section 321 (i.e., the filter water inlet), which can easily affect subsequent water accumulation treatment over time. This embodiment takes into account that when the water pump 31 stops absorbing water, the water remaining in the suction pipe 32 is in a static equilibrium state due to hydrostatic forces. If the suction pipe 32 has an opening, the pressure balance is broken, and water can flow back downward under the action of gravity, enabling backwashing of the lower end of the filter pipe section 321. To this end, this embodiment provides a backwash device 4 in the suction pipe 32. The backwash device 4 includes a pressure relief valve 41, a three-way switching valve 42, and a cleaning wastewater collection box 43. The pressure relief valve 41, such as a solenoid valve or a manual ball valve, is located at the upper end of the filter pipe section 321. The lower end of the filter pipe section 321 is connected to the cleaning wastewater collection box 43 via the vertical channel of the three-way switching valve 42, and is connected to the suction pipe water inlet 320 via the transverse channel of the three-way switching valve 42. When the water pump 31 is started to absorb water, the pressure relief valve 41 is closed, the three-way switching valve 42 has the horizontal channel open and the vertical channel closed, and the water inlet 320 of the water suction pipe is connected to the filter pipe section 321. Under the action of the water pump 31, the road surface water flows upward from the water inlet 320 through the filter pipe section 321 for filtration, then flows into the top of the water tank 1 through the water pump 31 and the outlet pipe 33, and then falls into the water tank 1 after being filtered by the filter screen 2. After the road surface water has been completely absorbed, the user turns off the water pump 31 to stop absorbing water. After the water pump 31 stops absorbing water, the user switches the three-way switching valve 42 to the vertical channel open and the horizontal channel closed, and then opens the pressure relief valve 41. The water remaining in the water suction pipe 32 then flows back downward under the action of gravity, thereby backwashing the lower end of the filter pipe section 321, and then flows vertically into the cleaning sewage collection box 43. Preferably, the cleaning wastewater collecting box 43 is detachably connected to the three-way switching valve 42 , and the user can remove the cleaning wastewater collecting box 43 for wastewater treatment.

[0018] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
