[0040] Next, in combination with the specific embodiments of the present utility model, the technical solutions in the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0041] As Figures 1-5 shown, a vehicle-mounted water pumping and draining system of the present utility model includes a water pump 1, a tank body 2, a connecting pipeline 3, a water spraying assembly 4 and a filter 5, and is fixedly installed on the vehicle body 6 of a special vehicle to achieve functions such as fire extinguishing, drought-resistant water transportation, emergency drainage, environmental sanitation cleaning and landscaping.

[0042] Among them, the water pump 1 is used to drive the water body for transportation. The water pump 1 is provided with a water inlet 101 and a drain outlet 102. The water body is pumped into the water pump 1 from the water inlet 101 and then discharged from the water pump 1 along the drain outlet 102.

[0043] The tank body 2 is used for storing water.

[0044] The connecting pipeline 3 is used for conveying water. The connecting pipeline 3 includes a circulating pipe 31, a water suction pipe 32, a water suction three-way valve 33, a water discharge pipe 34, a water discharge three-way valve 35 and a communicating pipe 36. Among them, both ends of the circulating pipe 31 are hermetically communicated with the water inlet 101 and the water discharge port 102 respectively; one end of the water suction pipe 32 is hermetically communicated with the circulating pipe 31 through the water suction three-way valve 33; one end of the water discharge pipe 34 is hermetically communicated with the circulating pipe 31 through the water discharge three-way valve 35; both ends of the communicating pipe 36 are hermetically communicated with the circulating pipe 31 and the tank body 2 respectively; the water suction pipe 32, the communicating pipe 36 and the water discharge pipe 34 are arranged in sequence along the direction from the end of the circulating pipe 31 connected to the water inlet 101 to the end connected to the water discharge port 102; both the water suction three-way valve 33 and the water discharge three-way valve 35 have three interfaces. By controlling them, two of the interfaces can be selectively made to communicate with each other. As Figure 2 shown in the figure, by controlling the water suction three-way valve 33 and the water discharge three-way valve 35, the water suction pipe 32 is communicated with the end of the circulating pipe 31 connected to the water inlet 101, and the water discharge pipe 34 is not communicated with the circulating pipe 31. When the water suction pipe 32 is communicated with the water source and the water pump 1 is started, the water in the water source enters the tank body 2 along the path of the water suction pipe 32 - water suction three-way valve 33 - circulating pipe 31 - water pump 1 - circulating pipe 31 - water discharge three-way valve 35 - communicating pipe 36, so as to store water or perform operations such as emergency drainage and flood fighting; on the contrary, by controlling the water suction three-way valve 33 and the water discharge three-way valve 35, the water suction pipe 32 is not communicated with the circulating pipe 31, and the water discharge pipe 34 is communicated with the end of the circulating pipe 31 connected to the water discharge port 102. When the water pump 1 is started, the water in the tank body 2 is discharged to the outside of the tank body 2 along the path of the communicating pipe 36 - water suction three-way valve 33 - circulating pipe 31 - water pump 1 - circulating pipe 31 - water discharge three-way valve 35 - water discharge pipe 34, so as to perform operations such as fire fighting, road cleaning or garden irrigation; the pipeline parts for water suction and water discharge in the connecting pipeline 3 partially overlap and are connected to the tank body 2 through a pipeline, thereby integrating and simplifying the connecting pipeline 3, which is beneficial to reducing the occupied space of the connecting pipeline 3 and contributing to the streamlined design of the vehicle; of course, corresponding air pressure relief ports, including inspection ports, etc., should also be opened on the tank body 2.

[0045] When the water extraction and discharge system is connected to a fire hydrant for extracting the water in the fire hydrant, the water suction pipe 32 can be removed and the fire pipeline can be directly connected to the interface of the water outlet three-way valve 33 where the water suction pipe 32 is installed.

[0046] The water spraying assembly 4 is used to achieve different water discharge functions. The water spraying assembly 4 includes a water outlet pipe 41, a water outlet control valve 42, a lifting pipe 45, a fire control valve 46 and a fire water cannon 47. Both the water outlet control valve 42 and the fire control valve 46 are single-way control valves for controlling the on-off of the pipeline. As Figure 1As shown, the middle position of the water outlet pipe 41 is in sealed communication with one end of the water discharge pipe 34 away from the water discharge three-way valve 35; the water outlet control valves 42 are respectively connected and arranged at both ends of the water outlet pipe 41. When the water outlet control valves 42 are opened, water can be sprayed from both ends of the water outlet pipe 41, thereby realizing its water discharge function. Water can be discharged from both sides of the vehicle body 6, so that the vehicle body 6 can adapt to different application environments.

[0047] As Figure 3 shown, one end of the lift pipe 45 is in sealed communication with the water outlet pipe 41; the fire control valve 46 is in sealed communication inside the lift pipe 45; the fire water cannon 47 is in sealed communication with the end of the lift pipe 45 away from the water outlet pipe 41 and is rotatably connected to the lift pipe 45. When the fire control valve 46 is opened, the fire water cannon 47 can spray high-pressure water jets for fire extinguishing operations, and the fire water cannon 47 can rotate with the lift pipe 45. Therefore, the adjustability of the fire water cannon 47 can be improved.

[0048] As Figure 5 shown, there are two water spraying assemblies 4, which are respectively fixedly arranged in front of and behind the vehicle body 6 and are respectively in sealed communication with one end of the water discharge pipe 34 away from the circulation pipe 31, thereby expanding the application range of the vehicle.

[0049] The fire water cannon 47 located behind the vehicle body 6 is located above the tank 2, so that the two fire water cannons 47 can adapt to fire environments at different positions. As Figure 4 shown, since the length of the lift pipe 45 in front of the vehicle body 6 is relatively short, the fire control valve 46 located in front of the vehicle body 6 is set as a pneumatic control valve installed inside the pipeline, which is not shown in the figure.

[0050] In order to improve the function of the water spraying assembly 4, the water spraying assembly 4 located in front of the vehicle body 6 further includes a deflecting pipe 43 and a nozzle 44. As Figure 4 shown, one end of the deflecting pipe 43 is in sealed communication with the end of the water outlet control valve 42 away from the water outlet pipe 41, and it is U-shaped to deflect the water column; the nozzle 44 is in sealed communication with the end of the deflecting pipe 43 away from the water outlet control valve 42, and it has a conical tubular structure, thereby increasing the spraying pressure of the water column; specifically, the deflecting pipe 43 and the nozzle 44 are both arranged on the two water outlet control valves 42 in front of the vehicle body 6, and the two deflecting pipes 43 and the two nozzles 44 are symmetrically arranged about the center line of the vehicle body 6, so as to achieve a counter-flushing effect to wash and clean the components or the ground between the two nozzles 44.

[0051] As Figure 1As shown in the figure, the water discharge pipe 34 includes a front water discharge pipe 341 and a rear water discharge pipe 342. The water discharge three-way valve 35 includes a three-way connector 351 and a rear vehicle three-way valve 352. Among them, one end of the front water discharge pipe 341 is hermetically connected to the circulation pipe 31 through the three-way connector 351, and the other end is arranged in front of the vehicle body 6. The three-way connector 351 is the three-way; one end of the rear water discharge pipe 342 is hermetically connected to the circulation pipe 31 through the rear vehicle three-way valve 352, and the other end is arranged behind the vehicle body 6; the two water outlet pipes 41 are respectively connected to the front water discharge pipe 341 and the rear water discharge pipe 342, so as to separately control the water bodies in the two water spraying assemblies 4.

[0052] As Figure 4 shown in the figure, the fire water monitor 47 includes a three-way pipe 471, two branch pipes 472 and a spray pipe 473. Among them, the three-way pipe 471 is hermetically connected to and rotatably connected to one end of the lifting pipe 45 far from the water outlet pipe 41 and one end of the two branch pipes 472. The two branch pipes 472 are symmetrically arranged with respect to the center point of the three-way pipe 471; one end of the spray pipe 473 is fixedly arranged between the ends of the two branch pipes 472 far from the three-way pipe 471 and is hermetically connected to its interior; the spray pipe 473 can rotate 360 degrees around the three-way pipe 471, so that the water column in the spray pipe 473 can face different directions, improving the spraying range of the fire water monitor 47.

[0053] The filter 5 is used to filter impurities in the connecting pipeline 3. The filter 5 is hermetically connected between the water inlet 101 and the circulation pipe 31 to prevent impurities from blocking the water pump 1.

[0054] The usage method of a vehicle-mounted pumping and water discharging system of the present utility model is as follows:

[0055] Pumping operation: First, insert the water suction pipe 32 into the water source or the flooded position, then open the water suction three-way valve 33, close the water outlet control valve 42, the fire control valve 46 and the rear vehicle three-way valve 352, so that one end of the water suction pipe 32 and the circulation pipe 31 connected to the water inlet 101 are connected. Finally, start the water pump 1, and the water body connected to the water suction pipe 32 can flow into the tank body 2 along the connecting pipeline 3.

[0056] Water discharging operation: First, close all control valves, then start the water pump 1 to make the water body in the tank body 2 circulate in the circulation pipe 31. Finally, by controlling the rear vehicle three-way valve 352, the water outlet control valve 42 or the fire control valve 46, the water body in the tank body 2 can be sprayed out from both ends of the water outlet pipe 41, the nozzle 44 or the fire water monitor 47.

[0057] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
