An internal pipeline 11 is provided inside the water tank 1, and an external pipeline 12 is provided outside the water tank 1. The internal pipeline 11 and the external pipeline 12 are connected. A water filling port 13 is provided at the bottom of the water tank 1, and an exhaust port 14 is provided at the top of the water tank 1; the water tank 1, water pump 2, hydraulic motor 3, and transmission shaft 4 are respectively installed on the water tank bracket 8, and the two ends of the transmission shaft 4 are respectively connected to the rotating shafts of the water pump 2 and the hydraulic motor 3.

The exhaust port 14 is used to balance the internal and external pressures of the water tank 1.

[0026] The internal pipeline 11 includes a main pipeline and a branch pipeline. The branch pipeline is connected to the main pipeline. The outlet of the water pump 2 is connected to the main pipeline. The external pipeline 12 is connected to the branch pipeline.

[0027] Working Principle: Water pump 2, a centrifugal pump, serves as the power source and is driven by hydraulic motor 3. Its function is to convert mechanical energy into liquid pressure energy, providing power to the entire system. Water tank 1 stores water, while hydraulic motor 3 provides power to water pump 2. Drive shaft 4 connects hydraulic motor 3 and water pump 2. Electronically controlled butterfly valves 15 control the flow of various water channels. Remote-controlled water monitors 6 deliver water to remote locations with high flow requirements. Low-pressure sprinkler nozzles 5 are responsible for daily dust suppression on the road surface, injecting water into water tank 1 through water inlet 13. Drain outlet 81 drains water from water tank 1 and provides water for other equipment.

[0028] The water tank 1 is installed on the water tank bracket 8. The chassis of the mining vehicle provides power for the hydraulic motor 3. The hydraulic motor 3 provides power for the water pump 2 through the transmission shaft 4. The water pump 2 rotates and sends the water in the water tank 1 to the internal pipeline 11. Through the internal pipeline 11, it reaches each electric-controlled butterfly valve 15. Among them, the electric-controlled butterfly valve 15 at the low-sprinkler nozzle 5 controls the left low-sprinkler and the right low-sprinkler respectively, and the electric-controlled butterfly valve 15 of the remote-controlled water cannon 6 controls the remote-controlled water cannon. When all the electric-controlled butterfly valves 15 are not energized, the internal pipeline 11 is in a closed state and no water flows out; when the electric-controlled butterfly valve 15 at the low-sprinkler nozzle 5 is energized and the electric-controlled butterfly valve 15 of the remote-controlled water cannon 6 is not energized, the electric-controlled butterfly valve 15 at the low-sprinkler nozzle 5 is opened to suppress the dust on the road surface; when the electric-controlled butterfly valve 15 of one remote-controlled water cannon 6 is energized and the electric-controlled butterfly valve 15 at the low-sprinkler nozzle 5 is not energized, the remote-controlled water cannon 6 starts to work, and the three remote-controlled water cannons 6 are adjusted to be parallel, and the remote-controlled water cannon 6 starts to work. The controlled water cannon 6 sprays to a medium distance, and the water columns of the three remote-controlled water cannons 6 are gathered together to be used as a high sprinkler nozzle; when the electric-controlled butterfly valves 15 of the two remote-controlled water cannons 6 are energized and the electric-controlled butterfly valves 15 at the low sprinkler nozzle 5 are not energized, the remote-controlled water cannon 6 is in a blasting dust suppression state and is used for blasting; the remote-controlled water cannon 6 and the electric-controlled butterfly valves 15 at the low sprinkler nozzle 5 are both energized, the remote-controlled water cannon 6 and the low sprinkler nozzle 5 are all opened, and the remote-controlled water cannon 6 acts as a high sprinkler to meet the daily dust suppression work on the road.

[0029] How to use the water system of a mine sprinkler truck, the steps are as follows:

[0030] (1) The electric butterfly valve 15 is de-energized and closed. At this time, the hydraulic motor 3 drives the water pump 2 to operate and output high-pressure water to the internal pipe 11;

[0031] Since the electric-controlled butterfly valves 15 are not opened, the high-pressure water is cut off at the electric-controlled butterfly valves 15 and no water is sprayed out through the low-sprinkler nozzles 5 or the remote-controlled water cannons 6.

[0032] (2) The electric-controlled butterfly valve 15 is energized, the electric-controlled butterfly valve 15 of the low-sprinkling sprinkler 5 is opened, the electric-controlled butterfly valve 15 of the remote-controlled water cannon 6 is closed, the electric-controlled butterfly valve 82 of the sewage outlet is closed, and high-pressure water is sprayed out from the low-sprinkling sprinkler 5 to implement the low-sprinkling dust suppression action;

[0033] (3) The electric-controlled butterfly valve 15 of the low-sprinkling sprinkler 5 and the electric-controlled butterfly valve 82 of the sewage outlet are closed, and the electric-controlled butterfly valve 15 of one remote-controlled water cannon 6 is energized. At this time, the hydraulic motor 3 drives the water pump 2 to operate, outputting high-pressure water, which reaches the electric-controlled butterfly valve 15 of the remote-controlled water cannon 6 through the internal pipeline 11. The high-pressure water is sprayed through the remote-controlled water cannon 6. Since only one electric-controlled butterfly valve 15 is opened, the spraying distance of the remote-controlled water cannon 6 is medium, and a high-sprinkling dust suppression action is implemented;

[0034] (4) The electric-controlled butterfly valve 15 of the low-sprinkler nozzle 5 and the electric-controlled butterfly valve 82 of the sewage outlet are closed, and the electric-controlled butterfly valves 15 of the remote-controlled water cannon 6 are all powered on and opened. At this time, the hydraulic motor 3 drives the water pump 2 to operate and output high-pressure water, which reaches the electric-controlled butterfly valve 15 of the remote-controlled water cannon 6 through the internal pipeline 11. The electric-controlled butterfly valves 15 of all the water cannons 6 are opened, and the high-pressure water is sprayed out by the remote-controlled water cannon 6. The spraying distance of the remote-controlled water cannon 6 is remote, and remote dust suppression action is implemented;

[0035] (5) The electric butterfly valve 82 at the sewage outlet is closed, and the electric butterfly valve 15 is fully opened. At this time, the hydraulic motor 3 drives the water pump 2 to operate and output high-pressure water, and the low-sprinkler nozzle 5 and the remote-controlled water cannon 6 work to implement high and low full coverage dust suppression action.

Since this utility model can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims.
