[0002] The mining water sprinkler sprays filtered water into the air and on the ground through a water storage tank, which is a key link for sprinkler dust suppression in open-pit coal mines. During the operation of the water sprinkler, the hydraulic system generates a relatively high temperature rise, resulting in the failure of the hydraulic system or a significant increase in the failure rate. Moreover, when the outdoor temperature is relatively low in winter, the pipelines of the water sprinkler will freeze.
[0003] In the prior art, a heating device is usually used to heat the frozen pipeline outside the pipeline. This requires additional heating equipment, which not only increases the cost, but also heats the pipeline passively and untimely, and additional space needs to be set aside for placing the heating device. Summary of the Utility Model
[0004] The utility model provides a water sprinkler to solve the problem that the water sprinkler pipeline in the prior art is prone to freezing at low outdoor temperatures, affecting the water sprinkling work.
[0005] The utility model provides a water sprinkler, which includes: a vehicle body with a water tank; a water sprinkler pipeline communicated with the water tank, the water sprinkler pipeline having a water sprinkling port; a driving mechanism drivingly connected to the water sprinkler pipeline, the driving mechanism being used to pump the water in the water tank into the water sprinkler pipeline, the driving mechanism having an oil pipeline; a cooler having a heat exchange channel and a refrigerant pipeline, the oil pipeline being communicated with the heat exchange channel, the refrigerant pipeline being used for heat exchange with the heat exchange channel, the cooler further having a liquid storage cavity, a liquid supply port and a liquid return port, the inlet of the refrigerant pipeline being communicated with the liquid supply port, the outlet of the refrigerant pipeline being communicated with the liquid return port, the liquid supply port and the liquid return port being respectively communicated with the liquid storage cavity, the refrigerant pipeline being able to cool down the oil in the oil pipeline, and the refrigerant heated by the refrigerant pipeline flowing into the liquid storage cavity; a heating assembly having a heating inlet and a heating outlet, the liquid supply port being communicated with the heating inlet, the heating outlet being communicated with the liquid return port, the heating assembly being arranged on the water sprinkler pipeline to heat the water sprinkler pipeline.
[0006] Further, the cooler includes a cooling box, a cooling pump and a cooling structure. The cooling box has a liquid storage cavity, a liquid supply port and a liquid return port. The cooling pump is arranged at the liquid supply port, and the cooling pump can pump the refrigerant in the cooling box into the refrigerant pipeline and the heating assembly. The cooling structure is arranged on the pipeline where the liquid supply port is communicated with the inlet of the refrigerant pipeline. When the outdoor temperature is relatively low in winter, the high-temperature refrigerant in the liquid storage cavity is pumped into the heating inlet through the cooling pump, and after entering the heating assembly, it heats the water sprinkler pipeline to raise the temperature of the water sprinkler pipeline and avoid freezing or damage of the water sprinkler pipeline.
[0007] Furthermore, the heating component includes a heating pipeline which has a heating inlet and a heating outlet, and the heating pipeline is wound around the outer periphery of the water sprinkling pipeline. With the above arrangement, compared with other heating structures, the design of the heating pipeline is simple, the processing cost is low, the occupied space is small, and it is convenient for installation and disassembly.
[0008] Furthermore, there are multiple heating pipelines. The multiple heating pipelines are wound around the outer periphery of the water sprinkling pipeline at intervals, and the multiple heating pipelines are respectively connected to a cooling pump. With the above arrangement, the contact area between the heating pipeline and the water sprinkling pipeline can be further increased, and the coverage rate of the heating pipeline on the water sprinkling pipeline can be increased. In this way, heat concentration or cold concentration on the water sprinkling pipeline can be avoided, the uniformity of heating of the water sprinkling pipeline can be ensured, and the occurrence of rupture or leakage of the water sprinkling pipeline caused by local overcooling or local overheating can be reduced.
[0009] Furthermore, the driving mechanism includes a hydraulic pump, a hydraulic oil tank, a motor and a water pump. The hydraulic pump has an oil suction port and an oil return port. The oil suction port is connected to the hydraulic oil tank. One end of the oil pipeline is connected to the oil return port, and the other end of the oil pipeline is connected to the motor. The motor is drivingly connected to the water pump, and the water pump is drivingly connected to the water tank. With the above arrangement, when the driving mechanism works, the oil suction port of the hydraulic pump is connected to the hydraulic oil tank, and the oil in the hydraulic oil tank is sucked in. After the oil is pressurized, it is transported to the motor through the oil return port, so that the motor drives the water pump to pump the water in the water tank into the water sprinkling pipeline and spray it out from the water sprinkling port for sprinkling work. After the oil releases energy, it returns to the hydraulic oil tank to form a cycle of the oil.
[0010] Furthermore, the sprinkler truck further includes a support frame which is located at the bottom of the water sprinkling pipeline and is used to support the water sprinkling pipeline. With the above arrangement, the stability of the water sprinkling pipeline can be improved, and it can be avoided that the water sprinkling pipeline shakes excessively when the sprinkler truck is running, which affects the sprinkling effect or causes the water sprinkling pipeline to collide with other components and be damaged.
[0011] Furthermore, the sprinkler truck further includes a plurality of buckles. The plurality of buckles are located between the support frame and the heating pipeline. The plurality of buckles are arranged on the support frame at intervals, and the heating pipeline is sequentially passed through the plurality of buckles. With the above arrangement, the buckles can not only fix the relative positions of the heating pipeline and the water sprinkling pipeline, prevent the heating pipeline from slipping off the water sprinkling pipeline, and ensure the heating effect of the heating pipeline on the water sprinkling pipeline.
[0012] Furthermore, the water tank extends along the length direction of the vehicle body, and both the hydraulic pump and the cooler are arranged at the tail of the water tank. With the above arrangement, the hydraulic pump and the cooler are integrated at the tail of the water tank, so as to improve the integration degree of the components, facilitate inspection and repair, and at the same time improve the rationality of the arrangement of the components in the sprinkler truck and the utilization rate of the internal space of the vehicle body.
[0013] Furthermore, a heat insulation layer is provided on the outer layer of the sprinkler pipeline. In this way, it can avoid the rapid temperature drop of the sprinkler pipeline after being heated by the heating pipeline, and delay the heating effect of the heating pipeline.
[0014] Furthermore, a temperature detector is also provided on the sprinkler pipeline. The temperature detection component is used to detect the water temperature in the sprinkler pipeline. In this way, the temperature of the sprinkler pipeline can be observed in real time. When the temperature drops to the preset temperature, the cooling pump is started to heat the sprinkler pipeline, so as to prevent the freezing of the sprinkler pipeline and thus extend the service life of the sprinkler pipeline.
[0015] Applying the technical solution of the present utility model, the heating component is communicated with the liquid storage cavity in the cooler. In this way, the refrigerant in the cooler will first flow from the liquid storage cavity to the refrigerant pipeline, and exchange heat with the oil in the heat exchange channel to cool down, so as to ensure the normal operation of the driving mechanism. At this time, the refrigerant heated after exchanging heat with the oil in the refrigerant pipeline flows back to the liquid storage cavity through the liquid return port. Then the heated refrigerant flows from the liquid supply port to the inlet of the heating component, and heats the sprinkler pipeline when flowing through the heating component, so as to avoid the freezing of the sprinkler pipeline when the outdoor temperature is relatively low. Subsequently, the refrigerant cooled after exchanging heat with the sprinkler pipeline flows back to the liquid storage cavity from the heating outlet of the heating component, waiting to enter the refrigerant pipeline for cooling work, thus forming a cycle. Through the above settings, the excess heat generated by the drive system is transferred to the sprinkler pipeline through the heating component, which can effectively avoid the freezing of the sprinkler pipeline, ensure the efficiency of the sprinkler work when the temperature is relatively low and reduce the failure maintenance rate of the sprinkler pipeline, and at the same time improve the energy utilization rate.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0031] As Figure 1 and Figure 2 shown, the embodiment of the present invention provides a sprinkler truck, which includes: a vehicle body 10, a water sprinkling pipeline 20, a driving mechanism 30, a cooler 40 and a heating assembly 50. Among them, the vehicle body 10 has a water tank 11. The water sprinkling pipeline 20 is communicated with the water tank 11, and the water sprinkling pipeline 20 has a water sprinkling port. The driving mechanism 30 is drivingly connected to the water sprinkling pipeline 20. The driving mechanism 30 is used to pump the water in the water tank 11 to the water sprinkling pipeline 20, and the driving mechanism 30 has an oil pipeline 31. The cooler 40 has a heat exchange channel and a refrigerant pipeline. The oil pipeline 31 is communicated with the heat exchange channel, and the refrigerant pipeline is used to exchange heat with the heat exchange channel. The cooler 40 also has a liquid storage cavity, a liquid supply port and a liquid return port. The inlet of the refrigerant pipeline is communicated with the liquid supply port, the outlet of the refrigerant pipeline is communicated with the liquid return port, and the liquid supply port and the liquid return port are respectively communicated with the liquid storage cavity. The refrigerant pipeline can cool down the oil in the heat exchange channel, and the refrigerant heated by the refrigerant pipeline flows into the liquid storage cavity. The heating assembly 50 has a heating inlet 51 and a heating outlet 52. The liquid supply port is communicated with the heating inlet 51, and the heating outlet 52 is communicated with the liquid return port. The heating assembly is arranged on the water sprinkling pipeline 20 to heat the water sprinkling pipeline 20.
[0032] Applying the technical solution of the present utility model, the heating component is communicated with the liquid storage cavity in the cooler 40. In this way, the refrigerant in the cooler 40 will first flow from the liquid storage cavity to the refrigerant pipeline, and exchange heat with the oil in the heat exchange channel to cool down, so as to ensure the normal operation of the driving mechanism. At this time, the refrigerant heated after exchanging heat with the oil in the refrigerant pipeline flows back to the liquid storage cavity through the liquid return port. Then the heated refrigerant flows from the liquid supply port to the inlet of the heating component, and when flowing through the heating component 50, it heats the sprinkler pipeline 20, so as to avoid the freezing of the sprinkler pipeline 20 when the outdoor temperature is relatively low. Subsequently, the refrigerant cooled after exchanging heat with the sprinkler pipeline 20 flows back to the liquid storage cavity from the heating outlet of the heating component 50, waiting to enter the refrigerant pipeline for cooling work, thus forming a cycle. Through the above settings, the excess heat generated by the drive system is transferred to the sprinkler pipeline 20 through the heating component 50, which can effectively avoid the freezing of the sprinkler pipeline 20, ensure the efficiency of the sprinkler work at low temperatures, reduce the failure repair rate of the sprinkler pipeline 20, and at the same time improve the energy utilization rate.
[0033] Preferably, the cooler 40 is a liquid-cooled cooler. The structure of the liquid-cooled cooler is simpler than that of other coolers, occupies a smaller area, and saves the internal space in the sprinkler truck.
[0034] In this embodiment, the specific structure of the heating component is not limited, and it can be a heating fin or a heating tube and other heating structures.
[0035] Specifically, as Figure 1 shown, the cooler 40 includes a cooling box 41, a cooling pump 42 and a cooling structure. The cooling box 41 has a liquid storage cavity, a liquid supply port and a liquid return port. The cooling pump 42 is arranged at the liquid supply port. The cooling pump 42 can pump the refrigerant in the cooling box 41 into the refrigerant pipeline and the heating component 50. The cooling structure is arranged on the pipeline where the liquid supply port is communicated with the inlet of the refrigerant pipeline. Through the above settings, the cooling pump 42 pumps the refrigerant in the cooling box 41 into the refrigerant pipeline, and cools down the refrigerant in the refrigerant pipeline through the cooling structure to ensure the cooling effect of the refrigerant. Subsequently, the cooled refrigerant exchanges heat with the oil flowing through the heat exchange channel to cool down the high-temperature oil, and at the same time the temperature of the refrigerant rises. The high-temperature refrigerant flows back from the refrigerant pipeline to the cooling box 41 for storage. When the outdoor temperature is relatively low in winter, the high-temperature refrigerant in the liquid storage cavity is pumped into the heating inlet 51 through the cooling pump 42, and after entering the heating component 50, it heats the sprinkler pipeline 20 to raise the temperature of the sprinkler pipeline 20 and avoid the freezing or damage of the sprinkler pipeline 20.
[0036] In this solution, the specific structure of the cooling structure is not limited, and it can be a water cooling tower, a cooling water pool or a refrigerating machine.
[0037] Further, the heating component includes a heating pipeline 53, which has a heating inlet 51 and a heating outlet 52. The heating pipeline 53 is wound around the outer periphery of the water sprinkling pipeline 20. With the above arrangement, compared with other heating structures, the design structure of the heating pipeline 53 is simple, the processing cost is low, the occupied space is small, and it is convenient for installation and disassembly. And winding the heating pipeline 53 around the outer periphery of the water sprinkling pipeline 20 can heat the water sprinkling pipeline 20 simultaneously in the axial direction and the circumferential direction, which can increase the contact area between the heating pipeline 53 and the water sprinkling pipeline 20, and then improve the heating effect of the heating component on the water sprinkling pipeline 20.
[0038] Moreover, with the above arrangement, the recycling of the refrigerant can be realized, and resources can be saved. At the same time, the temperature of the refrigerant in the heating pipeline 53 becomes lower after heat exchange with the water sprinkling pipeline 20, and it can flow back to the cooling tank 41 from the heating outlet 52 to reduce the temperature of the refrigerant in the cooling tank 41. In this way, when the refrigerant flows to the cooling structure, it is not necessary to cool the refrigerant significantly, so the energy consumption of the cooling structure can be reduced, and the energy utilization rate of each system in the water sprinkler truck can be improved.
[0039] In other embodiments of the present application, the heating pipeline 53 can also be arranged in a wavy structure or a bent structure and wound around the outer periphery of the water sprinkling pipeline 20.
[0040] Specifically, as Figure 1 and Figure 2 shown, there are multiple heating pipelines 53, and the multiple heating pipelines 53 are wound around the outer periphery of the water sprinkling pipeline 20 at intervals, and the multiple heating pipelines 53 are respectively communicated with the cooling pump 42. With the above arrangement, the contact area between the heating pipeline 53 and the water sprinkling pipeline 20 can be further increased, and the coverage rate of the heating pipeline 53 on the water sprinkling pipeline 20 can be increased. In this way, heat concentration or cold concentration on the water sprinkling pipeline 20 can be avoided, the uniformity of heating of the water sprinkling pipeline 20 can be ensured, and the occurrence of situations such as rupture or leakage of the water sprinkling pipeline 20 caused by local overcooling or local overheating can be reduced.
[0041] In the present application, the number of the heating pipelines 53 is not limited, and it can be set to 2, 3, 5 or more, and can be selected according to the actual size of the water sprinkling pipeline 20. In this embodiment, the heating pipeline 53 is set to 2.
[0042] Further, the end of the heating pipeline 53 adopts a quick plug-in connector, which is convenient for connecting and disconnecting the heating pipeline 53. In a non-low-temperature working environment, the connector is unplugged and the cooling pump 42 is turned off, which can save energy and can clean the heating pipeline 53 at the same time.
[0043] In this solution, as Figure 1As shown in the figure, the driving mechanism 30 includes a hydraulic pump 32, a hydraulic oil tank, a motor, and a water pump. The hydraulic pump 32 has an oil suction port and an oil return port. The oil suction port is communicated with the hydraulic oil tank. One end of the oil pipeline 31 is communicated with the oil return port, and the other end of the oil pipeline 31 is communicated with the motor. The motor is drivingly connected to the water pump, and the water pump is drivingly connected to the water tank 11. Through the above settings, when the driving mechanism 30 is working, the oil suction port of the hydraulic pump 32 is connected to the hydraulic oil tank, the piston in the hydraulic pump 32 starts to move, generating a negative pressure to suck the oil in the hydraulic oil tank. After pressurizing the oil, it is transported to the motor through the oil return port, and the hydraulic energy is converted into mechanical energy in the motor, so that the motor drives the water pump to pump the water in the water tank 11 into the sprinkler pipeline 20 and spray it out from the sprinkler nozzle for sprinkling work. After the oil releases energy, it returns to the hydraulic oil tank to form a cycle of the oil.
[0044] Specifically, as Figure 1 and Figure 2 shown in the figure, the sprinkler truck further includes a support frame 60. The support frame 60 is located at the bottom of the sprinkler pipeline 20 and is used to support the sprinkler pipeline 20. The support frame 60 is fixed to the bottom of the sprinkler truck by bolts. Through the above settings, the stability of the sprinkler pipeline 20 can be improved, and it can be avoided that the sprinkler pipeline 20 shakes excessively when the sprinkler truck is driving, which affects the sprinkling effect or causes the sprinkler pipeline 20 to collide with other components and be damaged.
[0045] In this application, the specific structure of the support frame 60 is not limited. It can be composed of a top plate and multiple vertical beams in cooperation. It can also be composed of multiple vertical beams and multiple cross beams in cooperation.
[0046] Furthermore, as Figure 1 and Figure 2 shown in the figure, the sprinkler truck further includes a plurality of buckles. The plurality of buckles are located between the support frame 60 and the heating pipeline 53. The plurality of buckles are arranged at intervals on the support frame 60, and the heating pipeline 53 passes through the plurality of buckles in sequence. Through the above settings, the buckles can not only fix the relative positions of the heating pipeline 53 and the sprinkler pipeline 20, prevent the heating pipeline 53 from slipping off the sprinkler pipeline 20, but also ensure the heating effect of the heating pipeline 53 on the sprinkler pipeline 20.
[0047] Among them, the water tank 11 extends along the length direction of the vehicle body 10, and both the hydraulic pump 32 and the cooler 40 are arranged at the tail of the water tank 11. Through the above settings, the hydraulic pump 32 and the cooler 40 are integrated at the tail of the water tank 11, so as to improve the integration degree of the components, facilitate inspection and repair, and at the same time improve the rationality of the component layout in the sprinkler truck and the utilization rate of the internal space of the vehicle body.
[0048] Furthermore, a heat insulation layer is provided on the outer layer of the sprinkler pipeline 20. In this way, it can be avoided that the temperature of the sprinkler pipeline 20 drops too fast after being heated by the heating pipeline 53, and the heating effect of the heating pipeline 53 can be delayed.
[0049] Specifically, a thermometer is also provided on the sprinkler pipeline 20, and the temperature detection component is used to detect the water temperature in the sprinkler pipeline 20. In this way, the temperature of the sprinkler pipeline 20 can be observed in real time. When the temperature drops to the preset temperature, the cooling pump 42 is started to heat the sprinkler pipeline 20, so as to prevent the sprinkler pipeline 20 from freezing and further extend the service life of the sprinkler pipeline 20.
[0050] Among them, the sprinkler truck further includes a traveling part and a cab. The traveling part is arranged at the bottom of the vehicle body, and the cab is arranged at one end of the vehicle body. The driver drives the vehicle body to travel by controlling the traveling part in the cab.
