[0022] As mentioned above, traditional mining sprinkler trucks are modified from ordinary chassis, have poor adaptability to road conditions, small water tank loading capacity, insufficient power, narrow spraying width, short spraying mileage, and low operating efficiency, which cannot meet the economic requirements of mine operation.

[0023] In order to solve at least one of the technical problems existing in the prior art or related technology, the present application provides a multifunctional mining sprinkler truck and a control method, the multifunctional mining sprinkler truck comprising: a vehicle body; a water tank, which is arranged on the vehicle body and connected to a water system; the water system comprises: a water pump, the water inlet of the water pump is connected to a first water outlet of the water tank through a pipeline, and the second water outlet of the water tank is connected to a water outlet of the water pump through a pipeline; a first control valve, which is arranged on the pipeline of the first water outlet of the water tank; a second control valve, which is arranged on the pipeline of the second water outlet of the water tank; a first sprinkler nozzle, which is connected to the water outlet of the water pump through a pipeline; a third control valve, which is arranged on the pipeline of the first sprinkler nozzle; a second sprinkler nozzle, which is connected to the water outlet of the water pump through a pipeline; a fourth control valve, which is arranged on the pipeline of the second sprinkler nozzle; a spray head, which is connected to the water outlet of the water pump through a pipeline; a fifth control valve, which is arranged on the pipeline of the spray head; and a hydraulic system for providing power for the water pump. Through the first sprinkler head, the second sprinkler head and the spray head, low sprinkler, high sprinkler, gravity sprinkler, spray and other functions can be realized. This multifunctional mining sprinkler truck has strong environmental adaptability, stable operation, high operating efficiency, large spraying volume, wide spraying range and long spraying distance. It can meet the needs of large open-pit mines for long-distance and wide-road sprinkling, dust reduction and even long-distance fire extinguishing. It is a production support vehicle with relatively complete functions for large open-pit mines.

[0024] The following describes a multifunctional mining sprinkler truck according to some embodiments provided by the present application with reference to the accompanying drawings.

[0025] See also Figures 1 to 5 The first embodiment of the present application provides a multifunctional mining water sprinkler, comprising: a vehicle body 1; a water tank 2, which is arranged on the vehicle body 1 and connected to a water system 3; the water system 3 comprises: a water pump 310, the water inlet of the water pump 310 is connected to a first water outlet of the water tank 2 through a pipeline, and the second water outlet of the water tank 2 is connected to a water outlet of the water pump 310 through a pipeline; a first control valve 31, which is arranged on the pipeline of the first water outlet of the water tank 2; a second control valve 32, which is arranged on the pipeline of the second water outlet of the water tank 2 On; a first sprinkler head 311 is connected to the water outlet of the water pump 310 through a pipeline; a third control valve 33 is arranged on the pipeline of the first sprinkler head 311; a second sprinkler head 312 is connected to the water outlet of the water pump 310 through a pipeline; a fourth control valve 34 is arranged on the pipeline of the second sprinkler head 312; a spray head 313 is connected to the water outlet of the water pump 310 through a pipeline; a fifth control valve 35 is arranged on the pipeline of the spray head 313; a hydraulic system 4 is used to provide power for the water pump 310.

[0026] The vehicle body 1 can be a mining dump truck, which is also called a mining dump truck or an off-road mining dump truck. It is a dump truck specially designed for transporting coal, sand and other materials in off-road field sites, such as large open-pit mines and water conservancy projects. It has the advantages of high reliability, high attendance rate, high adaptability, passability, power and operation efficiency, and long service life of key structural parts. The carriage of the mining dump truck is replaced with a water tank 2, which has a larger loading tonnage, so that the spraying mileage of the mining sprinkler truck is extended, the situation of repeated watering and empty running is avoided, and the economy is improved.

[0027] In an illustrative embodiment, Figure 3 As shown, the bottom of the water tank 2 is connected to the vehicle body 1 via a pin 11. The bottom of the water tank 2 is connected to the rear chassis of the vehicle body 1 via a pin 11, and the pin 11 can effectively prevent the water tank 2 from being displaced forward and backward on the chassis of the vehicle body 1; in addition to the forward and backward displacement, the pin 11 can also effectively prevent the water tank 2 from tilting left and right; and the use of the pin 11 makes the disassembly and assembly of the water tank 2 and the rear chassis of the vehicle body 1 simple and quick. The use of the pin 11 connection method can maintain the balance of the water tank 2 under complex or rugged road conditions, avoiding safety hazards caused by shaking or displacement. Compared with traditional connection methods such as U-bolts and limit plates, the pin 11 connection does not require complicated bolt tightening or limit plate adjustment processes, thereby saving time and energy.

[0028] The water tank 2 is used to provide water for spraying for the water system 3, such as Figure 4 As shown, the waterway system 3 includes: a first sprinkler nozzle 311, a second sprinkler nozzle 312 and a spray head 313, wherein the first sprinkler nozzle 311 adopts a duckbill nozzle, which is a special duckbill shape design, so that the water flow can form a specific spray angle and pressure distribution when spraying. The number of the first sprinkler nozzles 311 can be four, which are arranged at the rear of the vehicle body 1 and can spray facing the rear of the vehicle body 1. The third control valve 33 adopts an electrically controlled butterfly valve, which can control the first sprinkler nozzle 311 to be opened or closed, so that the first sprinkler nozzle 311 can spray water at a lower height and a larger flow rate to the rear of the vehicle body 1, and the spraying width is greater than 12m, which can more effectively distribute water on the surface of the mining road, thereby reducing dust.

[0029] The second sprinkler nozzle 312 adopts an adjustable water gun nozzle. The adjustable water gun nozzle is a water gun component that can adjust the shape, strength and direction of the water flow according to actual needs. By rotating the shaft, the angle of the nozzle can be changed to achieve the control of the direction of the water flow. The second sprinkler nozzle 312 is arranged at the rear of the vehicle body 1, and two nozzles are arranged on the left and right sides of the vehicle body 1, which can spray on both sides of the vehicle body 1. The fourth control valve 34 adopts an electrically controlled butterfly valve, and there are two of them, which respectively control the opening or closing of the two second sprinkler nozzles 312 on the left and right sides of the vehicle body 1, so that the second sprinkler nozzle 312 can spray water on both sides of the vehicle body 1 at a higher height and a larger flow rate. The high-position spraying can effectively cover the stacked coal and reduce dust flying.

[0030] The number of spray heads 313 can be twenty, and a spray pipe is used. The spray pipe is a pipe system specially designed to atomize liquid into fine particles and spray it out. When the liquid flows through the nozzle of the high-pressure spray pipe, due to the special design of the nozzle, the liquid is accelerated and dispersed into fine droplets, and then sprayed out. The spray head 313 is set on the top of the water tank 2, and can spray on both sides and the rear of the vehicle body 1. The fifth control valve 35 adopts an electrically controlled butterfly valve, which can control the spray head 313 to open or close, so that the spray head 313 sprays on both sides and the rear of the vehicle body 1 at a higher height and a larger flow rate, which can ensure a wide spray range and effectively cover the two sides and the rear area of ​​the vehicle body 1.

[0031] In an illustrative embodiment, Figure 2 As shown, the first sprinkler head 311 is arranged below the water tank 2; the spray head 313 is arranged at the top of the water tank 2; and the second sprinkler head 312 is located between the first sprinkler head 311 and the spray head 313. The spray head 313 is at the top of the water tank 2, the first sprinkler head 311 is at the bottom of the water tank 2, and the second sprinkler head 312 is in the middle. By arranging the sprinklers at different heights of the water tank 2, multi-level and all-round spray or watering coverage can be achieved; different sprinklers can be independently controlled to achieve different spray or watering modes. At the same time, the first sprinkler head 311, the second sprinkler head 312 and the spray head 313 can be connected by a pipe. In the traditional design, each sprinkler head may need a separate pipe for connection. The design of connecting multiple sprinklers with one pipe can significantly reduce the number of pipes, thereby saving a lot of installation space.

[0032] In an illustrative embodiment, the water system 3 further includes: a fire water monitor 314 connected to the water outlet of the water pump 310 through a pipeline; and a sixth control valve 36 disposed on the pipeline of the fire water monitor 314 .

[0033] The fire monitor 314 is arranged in front of the vehicle body 1 and is used to extinguish fires at a long distance, and the range can be greater than 60 meters. The sixth control valve 36 is a manual ball valve, which can control the fire monitor 314 to open or close, so that the fire monitor 314 sprays water in front of the vehicle body 1 with a large flow rate, so as to quickly reduce the temperature of the fire source, extinguish the flames or prevent the fire from spreading.

[0034] In an illustrative embodiment, the water system 3 further includes: a fire hydrant interface 315 connected to the water outlet of the water pump 310 through a pipeline; and a seventh control valve 37 disposed on the pipeline of the fire hydrant interface 315 .

[0035] The fire hydrant interface 315 is arranged on both sides of the vehicle body 1, and is used to connect the fire water bag. The fire water bag, also known as the fire hose, is a hose used to deliver water at the fire scene, and plays a vital role in fire fighting and rescue. The seventh control valve 37 adopts a manual ball valve, which can control the opening or closing of the fire hydrant interface 315, so that the fire hydrant interface 315 supplies water to the connected fire water bag at a large flow rate, ensuring that firefighters can quickly and conveniently obtain water at the fire scene, so as to quickly and effectively carry out fire fighting operations.

[0036] In an illustrative embodiment, the water system 3 further includes: a water pumping interface 316 connected to the water inlet of the water pump 310 through a pipeline; and an eighth control valve 38 disposed on the pipeline of the water pumping interface 316 .

[0037] The pumping interface 316 is provided on one side of the vehicle body 1 for connecting a pumping pipe, which can be placed in the river water, so that when the water source is short, the river water can be pumped to replenish the water tank 2. The eighth control valve 38 is a manual ball valve, which can control the pumping interface 316 to be opened or closed, so that the pumping interface 316 can supply water to the water tank 2 at a larger flow rate, thereby preventing the pumping of river water for operation when a specific water source is short.

[0038] In an illustrative embodiment, the water system 3 further includes: a filter 318, which is arranged on the pipeline of the water inlet of the water pump 310. The filter 318 is used to filter impurities in the water to ensure that the water entering the water pump 310 is relatively pure, thereby protecting the water pump 310 from damage by impurities and reducing the risk of malfunction caused by impurities.

[0039] In an illustrative embodiment, the water system 3 further includes: a drainage interface 317 connected to the water tank 2 through a pipeline; and a ninth control valve 39 disposed on the pipeline of the drainage interface 317 .

[0040] The drainage interface 317 is set at the lowest point of the water tank 2 for connecting the drainage pipe. The ninth control valve 39 adopts a manual ball valve, which can control the drainage interface 317 to open or close, drain the water tank 2, and empty the remaining water in the water tank 2 and the pipeline during maintenance and shutdown, which is convenient and simple to operate.

[0041] In an illustrative embodiment, Figure 5 As shown, the hydraulic system 4 includes: a double gear pump 42, the oil suction port of the double gear pump 42 is connected to the oil tank through a pipeline, the first oil outlet of the double gear pump 42 is connected to the confluence valve block 45 through a pipeline, and the second oil outlet of the double gear pump 42 is connected to the hydraulically controlled reversing valve 43 through a pipeline; the hydraulically controlled reversing valve 43 is respectively connected to the hydraulic motor 41 and the confluence valve block 45 through pipelines; the control valve group 44 is connected to the hydraulically controlled reversing valve 43 through a pipeline; the confluence valve block 45 is connected to the cooling circuit through a pipeline; the hydraulic motor 41 is connected to the water pump 310 through a coupling.

[0042] The hydraulic system 4 is modified by using the original cooling system of the mining dump truck. The double gear pump 42 is a special gear pump, which is composed of two gear pumps B1 and B2 into a pump body, and has two oil outlets and an oil suction port. The power output of the engine drives the double gear pump 42 to provide hydraulic power. The gear pump B1 corresponds to the first oil outlet of the double gear pump 42, and supplies fluid to the original cooling circuit of the mining dump truck; the gear pump B2 corresponds to the second oil outlet of the double gear pump 42, and supplies fluid to the hydraulic motor 41.

[0043] The hydraulic motor 41 is a power element that converts hydraulic energy into mechanical energy. Based on the oil pressure energy and flow provided by the gear pump B2, it drives the internal mechanical parts to rotate or reciprocate, thereby outputting mechanical energy for driving the water pump 310. The hydraulic motor 41 is small in size and can be arranged at will without being constrained by space, so as to achieve high power transmission.

[0044] The control valve group 44 is used to control the connection direction of the hydraulic control reversing valve 43. The hydraulic control reversing valve 43 is used to control the second oil outlet of the double gear pump 42 to be connected with the hydraulic motor 41, or the second oil outlet of the double gear pump 42 is connected with the hydraulic motor 41 to the confluence valve block 45, that is, the gear pump B2 supplies fluid to the hydraulic motor 41, or the gear pump B2 supplies fluid to the confluence valve block 45. When the water pump 310 needs to be turned on, the hydraulic control reversing valve 43 is controlled by the control valve group 44 to make the gear pump B2 supply fluid to the hydraulic motor 41, thereby driving the water pump 310; when the water pump 310 needs to be turned off, the hydraulic control reversing valve 43 is controlled by the control valve group 44 to make the gear pump B2 supply fluid to the confluence valve block 45, and the confluence valve block 45 is used to merge the fluids supplied by the gear pumps B1 and B2 and supply them to the cooling circuit, thereby turning off the water pump 310.

[0045] In an illustrative embodiment, the hydraulic system 4 further includes: a relief valve 46, which is arranged between the liquid inlet pipeline and the liquid return pipeline of the hydraulic control reversing valve 43. The relief valve 46 is used to control the maximum pressure of the oil circuit for the gear pump B2 to supply oil to the hydraulic motor 41. When the pressure between the pipelines exceeds the set value of the relief valve 46, the relief valve 46 will open to allow part of the hydraulic oil to flow back to the oil tank, thereby maintaining the pressure within the set range.

[0046] A multifunctional mining sprinkler control method provided in the second embodiment of the present application is applied to a multifunctional mining sprinkler provided in the first embodiment of the present application, including: When the low watering strategy is executed, the water pump 310 is controlled to be turned on, the second control valve 32 is controlled to be closed, and the first control valve 31 and the third control valve 33 are controlled to be opened.

[0054] When the water cannon fire extinguishing strategy is executed, the water pump 310 is controlled to be turned on, the second control valve 32 is controlled to be closed, and the first control valve 31 and the sixth control valve 36 are controlled to be opened.

[0055] The water cannon fire extinguishing strategy is to make the fire cannon 314 spray water at a large flow rate in front of the vehicle body 1. The water pump 310 is controlled to open by the rocker switch in the cab, the second control valve 32 is controlled to close, and the first control valve 31 and the sixth control valve 36 are controlled to open, so that the water pump 310 draws water from the water tank 2 and flows through the first control valve 31 and the sixth control valve 36 to the fire cannon 314.

[0056] When the fire hydrant fire extinguishing strategy is executed, the water pump 310 is controlled to be turned on, the second control valve 32 is controlled to be closed, and the first control valve 31 and the seventh control valve 37 are controlled to be opened.

[0058] When the water pumping strategy is executed, the water pump 310 is controlled to be turned on, the first control valve 31 is controlled to be closed, and the second control valve 32 and the eighth control valve 38 are controlled to be opened.
