Description

Technical Field

[0001] This utility model relates to the field of water sprinkler truck technology, and in particular to a water sprinkler system and a mining water sprinkler truck. Background Technology

[0002] Mining sprinkler trucks are highly adaptable to different environments, have low fuel consumption, stable operation, high operating efficiency, large spray volume, wide spray range, and long spray distance. They can meet the needs of large open-pit mines for watering and dust suppression on long-distance and wide-road surfaces, and even for long-distance fire extinguishing in coal mines. They are the most comprehensive production support vehicles for large open-pit mines.

[0003] However, existing mining sprinkler trucks generally use diesel engines as their power source. These trucks not only have high fuel consumption, but also, because they are single-powered, are prone to malfunctions when the engine fails, rendering them unable to operate. Therefore, mining sprinkler trucks with multiple power sources—that is, a power system including an engine, generator, and battery—can solve these problems. Thus, a sprinkler system applicable to multi-powered mining sprinkler trucks urgently needs research. Utility Model Content

The main control valve group is used to control the flow of hydraulic oil into the piston motor and / or the solenoid butterfly valve group. The solenoid butterfly valve group is used to control the on / off state of the pipeline assembly. The piston motor is connected to the output of the generator via a double gear pump. The piston motor is used to drive the centrifugal pump to control the water pressure in the pipeline assembly.

[0025] One of the above technical solutions has at least the following advantages or beneficial effects:

[0026] In one embodiment of the present invention, a water spraying system is constructed by connecting a water spraying assembly to a water tank via a pipeline assembly, and connecting a centrifugal pump to the pipeline assembly. The hydraulic control assembly is configured to include a main control valve group, a plunger motor, and a solenoid butterfly valve group, with the solenoid butterfly valve group positioned on the pipeline assembly. This allows the main control valve group to control hydraulic oil to enter the solenoid butterfly valve group, and when the solenoid butterfly valve group opens to connect to the pipeline assembly, the main control valve group controls a portion of the hydraulic oil to enter the plunger motor connected to the generator's output. This causes the plunger motor to drive the centrifugal pump, increasing the water pressure in the pipeline assembly. Consequently, the water in the pipeline assembly flows at higher pressure to the water spraying assembly, allowing at least two nozzles in the water spraying assembly to spray dust. Therefore, by connecting the plunger motor to the output of the generator in the power system via a double gear pump, this application can control the plunger motor to drive the centrifugal pump, enabling the water spraying system to be used on multi-powered mining water trucks.

[0027] The mining sprinkler truck provided in this embodiment of the utility model is equipped with the sprinkler system described above.

[0034] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Mining sprinkler trucks are designed for various mines, quarries, and other sites with large areas, high dust levels, and complex road surfaces. They are mainly used for road watering and dust suppression, emergency fire fighting, fire extinguishing road spraying, mine car cleaning, blasting, and transporting industrial water, among other functions.

[0036] However, most existing mining sprinkler trucks use ordinary truck chassis, which are poorly adapted to road conditions. Furthermore, the existing sprinkler systems in mining trucks are relatively cumbersome to operate.

[0037] To address at least one of the technical problems existing in the prior art or related technologies, this utility model provides a water spraying system. The system includes a water tank, a spraying assembly, a centrifugal pump, and a hydraulic control assembly. The water tank is mounted on a mining water truck. The spraying assembly is connected to the water tank via a pipeline assembly and includes at least two nozzles located at the rear of the mining water truck. The centrifugal pump is connected to the pipeline assembly. The hydraulic control assembly includes a main control valve group, a plunger motor, and an electromagnetic butterfly valve group. The main control valve group is connected to both the electromagnetic butterfly valve group and the plunger motor. The electromagnetic butterfly valve group is located on the pipeline assembly. The main control valve group controls the flow of hydraulic oil into the plunger motor and / or the electromagnetic butterfly valve group. The electromagnetic butterfly valve group controls the on / off state of the pipeline assembly. The plunger motor drives the centrifugal pump to control the water pressure in the pipeline assembly. This application connects the plunger motor to the output of a generator in the power system via a double gear pump, allowing the plunger motor to drive the centrifugal pump, thus enabling the application of the water spraying system on multi-powered mining water trucks.

[0038] The following describes, with reference to the accompanying drawings, some embodiments of the sprinkler system and mining sprinkler truck provided by the present invention.

[0039] See Figures 1 to 4This utility model provides a water spraying system according to an embodiment, applied to a mining water sprinkler truck. The power system of the mining water sprinkler truck includes an engine and a generator, with the generator connected to the output end of the engine. The water spraying system includes a water tank 1, a water spraying assembly, a centrifugal pump 2, and a hydraulic control assembly. The water tank 1 is mounted on the mining water sprinkler truck. The water spraying assembly is connected to the water tank 1 via a pipeline assembly 12 and includes at least two nozzles 3 located at the rear of the mining water sprinkler truck. The centrifugal pump 2 is connected to the pipeline assembly 12. The hydraulic control assembly includes a main control valve group 4, a plunger motor 5, and an electromagnetic butterfly valve group. The main control valve group 4 is connected to both the electromagnetic butterfly valve group and the plunger motor 5. The electromagnetic butterfly valve group is mounted on the pipeline assembly 12. The main control valve group 4 is used to control the flow of hydraulic oil into the plunger motor 5 and / or the electromagnetic butterfly valve group. The electromagnetic butterfly valve group is used to control the on / off state of the pipeline assembly 12. The plunger motor 5 is connected to the output end of the generator via a double gear pump and is used to drive the centrifugal pump 2 to control the water pressure in the pipeline assembly 12.

[0040] The water tank 1 has a volume of 30000 Gal (113.5m³). 3 The water tank 1 is mounted on the frame of the mining sprinkler truck, and at least two nozzles 3 can be fixed on the side of the water tank 1 away from the cab, so that at least two nozzles 3 are located at the rear of the mining sprinkler truck.

[0041] Since the power system of the mining sprinkler truck in this application includes an engine and a generator, the mining sprinkler truck in this application can be considered as a hybrid energy-saving vehicle, and its chassis can also be an electric wheel chassis; the generator in this application is connected to the output end of the engine, and the output shaft of the generator is connected to the plunger motor 5 through a double gear pump, so that the generator drives the double gear pump to provide hydraulic power to drive the centrifugal pump 2 to operate.

[0042] Here, the number of nozzles 3 is preferably 6. These 6 nozzles 3 are divided into two groups of nozzles 3, that is, each group of nozzles 3 includes 3 nozzles 3. The two groups of nozzles 3 are arranged symmetrically about the central axis of the water tank 1 at the rear of the mining sprinkler truck. One nozzle 3 in each group of nozzles 3 is close to the mining sprinkler truck so that it can spray dust on the side of the mining sprinkler truck. The other two nozzles 3 in each group of nozzles 3 are located on the plane at the rear of the mining sprinkler truck. These two nozzles 3 can spray dust on the rear of the mining sprinkler truck.

[0043] It should be noted that the electromagnetic butterfly valve assembly can be electrically connected to the control screen in the cab to realize the spray control of the nozzle 3 through the control screen in the cab. The spray shape, water volume and spray width of the nozzle 3 can be adjusted, and the spray width of the nozzle 3 can be greater than 20m.

[0044] In this embodiment, the water sprinkler assembly is connected to the water tank 1 via the pipeline assembly 12, and the centrifugal pump 2 is connected to the pipeline assembly 12. The hydraulic control assembly is selected to include a main control valve group 4, a plunger motor 5, and an electromagnetic butterfly valve group, with the electromagnetic butterfly valve group located on the pipeline assembly 12. This allows the main control valve group 4 to control hydraulic oil to enter the electromagnetic butterfly valve group, and when the electromagnetic butterfly valve group opens to connect to the pipeline assembly 12, the main control valve group 4 controls a portion of the hydraulic oil to enter the plunger motor 5 connected to the generator output. This causes the plunger motor 5 to drive the centrifugal pump 2, increasing the water pressure in the pipeline assembly 12. Consequently, the water in the pipeline assembly 12 flows at higher pressure to the water sprinkler assembly, allowing at least two nozzles 3 in the water sprinkler assembly to spray dust. Therefore, this application, by connecting the plunger motor 5 to the output of the generator in the power system via a double gear pump, can control the plunger motor 5 to drive the centrifugal pump 2, thus enabling the application of the water sprinkler system on multi-powered mining water sprinkler trucks.

[0045] In some possible embodiments, the hydraulic control assembly also includes a piston pump 6 connected to the main control valve assembly 4, which pumps hydraulic oil from the tank to the main control valve assembly 4.

[0046] It should be noted that the plunger pump 6 is driven by the engine's power take-off unit (PTO) so that the plunger pump 6 pumps the hydraulic oil in the oil tank to the main control valve group 4.

[0047] In this embodiment, by selecting a hydraulic control component that includes a piston pump 6, the operation of the piston pump 6 can be controlled to ensure that the hydraulic oil in the tank is smoothly pumped into the main control valve group 4, while also ensuring that the hydraulic oil entering the main control valve group 4 has a high oil pressure, thereby allowing the hydraulic oil entering the main control valve group 4 to smoothly enter the piston motor 5 connected to it.

[0048] Furthermore, a high-pressure filter 7 is provided between the plunger pump 6 and the main control valve assembly 4. The high-pressure filter 7 is used to filter the hydraulic oil pumped by the plunger pump 6 to the main control valve assembly 4.

[0049] In this embodiment, by setting a high-pressure filter 7 between the plunger pump 6 and the main control valve assembly 4, the hydraulic oil pumped by the plunger pump 6 to the main control valve assembly 4 can be filtered to prevent impurities in the hydraulic oil from entering the main control valve assembly 4 and causing damage to the main control valve assembly 4, the plunger motor 5 and the solenoid butterfly valve assembly.

[0050] In some possible embodiments, the sprinkler assembly also includes a water cannon 8, which is located on top of the water tank 1 and connected to the water tank 1 via a piping assembly 12.

[0051] Here, the water cannon 8 can be installed on top of the water tank 1 near the driver's cab.

[0052] It should be noted that the water cannon 8 has a range of more than 60m, and it can rotate 300° relative to the horizontal plane. The angle between the water jet it emits and the vertical direction is 20-70°.

[0053] In this embodiment, by setting a water cannon 8 on the top of the water tank 1, the water spraying assembly can comprehensively spray and reduce dust near the mining water truck through the combined use of the water cannon 8 and at least two nozzles 3, thereby improving the dust reduction efficiency of the mining water truck.

[0054] Furthermore, the piping assembly 12 includes a first piping and a second piping; at least two nozzles 3 are connected to the water tank 1 through the first piping, and the water cannon 8 is connected to the water tank 1 through the second piping; the electromagnetic butterfly valve assembly includes a first electromagnetic butterfly valve 9 and a second electromagnetic butterfly valve 10, with a first electromagnetic butterfly valve 9 provided on each first piping and a second electromagnetic butterfly valve 10 provided on each second piping; the first electromagnetic butterfly valve 9 is used to control the on / off state of the first piping connected to it, and the second electromagnetic butterfly valve 10 is used to control the on / off state of the second piping.

[0055] It should be noted that when the first electromagnetic butterfly valve 9 controls the isolation of the first pipeline connected to it, it can be understood that the water in the first pipeline is blocked by the first electromagnetic butterfly valve 9 so that the water in the first pipeline cannot flow to the nozzle 3 connected to the first pipeline, and at this time the water in the first pipeline has a certain water pressure; when the first electromagnetic butterfly valve 9 controls the connection of the first pipeline, the water in the first pipeline with a certain water pressure can flow to the nozzle 3 connected to the first pipeline so that the nozzle 3 can spray.

[0056] Here, since the first pipeline corresponding to each nozzle 3 is connected to a first electromagnetic butterfly valve 9, and the second pipeline connected to the water cannon 8 is connected to a second electromagnetic butterfly valve 10, and both the first electromagnetic butterfly valve 9 and the second electromagnetic butterfly valve 10 can be electrically connected to the control screen in the cab, at least two nozzles 3 and the water cannon 8 can be individually controlled by operating the control screen in the cab.

[0057] In some possible embodiments, the main control valve assembly 4 includes a pressure-reducing relief valve connected to the solenoid butterfly valve assembly for adjusting the oil pressure of the hydraulic oil to be introduced into the solenoid butterfly valve assembly.

[0058] Because the hydraulic oil pumped by the plunger pump 6 has a high oil pressure, the main control valve group 4 includes a pressure reducing relief valve structure, and the pressure reducing relief valve is connected to the solenoid butterfly valve group. This allows the oil pressure entering the solenoid butterfly valve group to be reduced and overflowed by the pressure reducing relief valve before entering the solenoid butterfly valve group, thus avoiding damage to the solenoid butterfly valve group caused by hydraulic oil with high oil pressure entering the solenoid butterfly valve group.

[0059] The connection between the pressure reducing relief valve and the solenoid butterfly valve group can be understood as follows: when the solenoid butterfly valve group includes the first solenoid butterfly valve 9 and the second solenoid butterfly valve 10, both the first solenoid butterfly valve 9 and the second solenoid butterfly valve 10 are connected to the pressure reducing relief valve through pipelines.

[0060] In some possible embodiments, the main control valve assembly 4 includes a pressure relief circuit connected to the piston motor 5 to limit the maximum oil pressure of the hydraulic oil to be introduced into the piston motor 5.

[0061] Because the hydraulic oil pumped by the plunger pump 6 has a high oil pressure, the main control valve group 4 includes a pressure relief circuit, and the pressure relief circuit is connected to the plunger motor 5 so that the maximum oil pressure entering the plunger motor 5 is limited, so as to avoid damage to the plunger motor 5 caused by hydraulic oil with excessively high oil pressure entering the plunger motor 5.

[0062] When the mining sprinkler truck does not need to spray water, the piston motor 5 can be in a standby state because the hydraulic oil in the pressure relief circuit has a certain oil pressure. When the mining sprinkler truck sprays water, the hydraulic oil with a certain oil pressure in the pressure relief circuit enters the piston motor 5, which can immediately drive the centrifugal pump 2 to work, so that the water in the pipeline assembly 12 has water pressure. By opening the first solenoid butterfly valve 9 and / or the second solenoid butterfly valve 10, the nozzle 3 or water cannon 8 can be controlled to spray water.

[0063] In addition, a cooler 11 is provided between the main control valve assembly 4 and the oil tank. The cooler 11 is used to cool the low-pressure oil in the main control valve assembly 4 so that the low-pressure oil flows into the oil tank after being cooled down.

[0064] In some possible embodiments, the water tank 1 is equipped with an overflow outlet, a level gauge, and a water level alarm device. The overflow outlet is used to discharge water exceeding a preset volume from the water tank 1; the level gauge is used to detect the water level in the water tank 1; and the water level alarm device is used to sound an alarm when the hydraulic pressure in the water tank 1 is lower than a preset height.

[0065] Here, the bottom of water tank 1 is provided with a drain outlet, which is used to drain the water in water tank 1.

[0066] In this embodiment, by setting an overflow outlet on the water tank 1, the overflow of water in the water tank 1 can be avoided; at the same time, by setting a level gauge on the water tank 1, the staff can know the water level in the water tank 1 in real time; in addition, by setting a water level alarm device, the staff can be reminded to add water to the water tank 1. The water level alarm device reminds the staff to add water to the water tank 1 through an audible and visual alarm.

[0067] One embodiment of the present invention provides a mining sprinkler truck, which includes a sprinkler system as described in any of the above embodiments.

[0068] Among them, the chassis of the mining sprinkler truck can adopt the chassis of the hybrid energy-saving electric wheel mining truck to improve the adaptability of the mining sprinkler truck chassis to road conditions.

[0069] Since the mining sprinkler truck of this embodiment includes any of the sprinkler systems in the first aspect above, it has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0070] In some possible embodiments, the mining sprinkler truck also includes an engine, a generator, and a double gear pump. The generator is connected to the output of the engine so that the engine charges the generator. The double gear pump is driven to the output shaft of the generator. The double gear pump is also driven to a plunger motor 5 to control the plunger motor 5 to drive the centrifugal pump 2.

[0071] The engine can provide power output to the generator for charging via a diaphragm coupling. The generator's output shaft drives a double gear pump, which in turn provides hydraulic power to drive the centrifugal pump 2 via the plunger motor 5. Furthermore, the double gear pump can also be connected to the electric wheel drive of the mining sprinkler truck to drive the electric wheel of the truck, thereby controlling the truck's movement.
