[0027] In coal transportation, the coal carried in the vehicle (for example, train) needs to be deiced and dusted. Currently, the deicing and dusting of the coal carried in the vehicle is usually achieved by spraying antifreeze liquid and dust suppression liquid to the coal in the moving vehicle. The spraying effect of the coal carried in the vehicle is often affected by the change of the driving speed of the vehicle. Currently, the spraying of the coal carried in the vehicle cannot adapt to the change of the driving speed of the vehicle, and it is difficult to uniformly spray the coal carried in the vehicle, resulting in poor deicing and dusting effect.

[0028] The utility model provides a variable spraying device 100.

[0029] Please refer to Figures 1 to 2 In an embodiment of the utility model, the variable spraying device 100 comprises a supporting mechanism 10, a speed measuring assembly and a spraying mechanism 20. The supporting mechanism 10 comprises a base 11 and a supporting arm 12 mounted on the base 11. The supporting arm 12 extends in the horizontal direction, and a space for vehicle driving is formed below the supporting arm 12. The speed measuring assembly is used to monitor the driving speed of the vehicle driving in the space. The spraying mechanism 20 comprises a liquid storage pipe 21, a liquid storage tank 22 and a variable frequency water pump 23. The liquid storage pipe 21 extends along the extension direction of the supporting arm 12 and is detachably connected to the supporting arm 12. A plurality of spraying structures 24 are installed at intervals along the extension direction of the liquid storage pipe 21. The liquid storage tank 22 is used to store liquid. The liquid storage tank 22 is in communication with the liquid storage pipe 21. The variable frequency water pump 23 and the speed measuring assembly are both in communication connection with a controller. The controller is used to control the variable frequency water pump 23 to pump the liquid in the liquid storage tank 22 to the liquid storage pipe 21 according to the driving speed, so as to spray liquid to the material carried on the vehicle through the spraying structures 24.

[0030] The technical scheme of the utility model comprises a base 11. The base 11 is provided with a supporting arm 12 extending in the horizontal direction. A space is formed below the supporting arm 12, which can be used for vehicle driving. A liquid storage pipe 21 is mounted on the supporting arm 12. The liquid storage pipe 21 is in communication with a liquid storage tank 22. The variable frequency water pump 23 can pump the antifreeze liquid or dust suppression liquid in the liquid storage tank 22 into the liquid storage pipe 21. A plurality of spraying structures 24 are arranged at intervals along the extension direction of the liquid storage pipe 21. The plurality of spraying structures 24 can spray liquid to the material (for example, coal) carried in the vehicle driving in the space from multiple points. The liquid can be more uniformly sprayed to the material carried in the vehicle, thereby improving the deicing and dusting effect of the coal carried in the vehicle.

[0031] Further, the speed measuring assembly can monitor the running speed of the vehicle running in the space below the support arm 12, and the controller can control the variable frequency water pump 23 according to the monitored running speed. In the case of monitoring the increase of the running speed of the vehicle, the controller controls the increase of the operating power of the variable frequency water pump 23 to increase the flow of the liquid pumped into the liquid storage pipe 21 per unit time, so as to increase the flow of the liquid sprayed from each spraying structure 24 per unit time, so as to adapt to the increase of the running speed of the vehicle; in the case of monitoring the decrease of the running speed of the vehicle, the controller controls the decrease of the operating power of the variable frequency water pump 23 to decrease the flow of the liquid pumped into the liquid storage pipe 21 per unit time, so as to decrease the flow of the liquid sprayed from each spraying structure 24 per unit time, so as to adapt to the decrease of the running speed of the vehicle, so that the spraying of the liquid to the material carried in the vehicle can adapt to the change of the running speed of the vehicle, so that the spraying of the liquid to the material carried in the vehicle can be more uniform, and the effect of preventing freezing and dust reduction of the coal carried in the vehicle is further improved.

[0032] It should be noted that the speed measuring assembly can adopt a radar speedometer in the prior art, and the controller can adopt a programmable logic controller in the prior art; the communication connection between the speed measuring assembly, the variable frequency water pump 23 and the controller adopts the prior art, and the interaction between the speed measuring assembly, the variable frequency water pump 23 and the controller adopts the prior art.

[0035] Specifically, as Figure 1 and Figure 2As shown, the spray pipe 241 is communicated with the liquid storage pipe 21, and the liquid in the liquid storage pipe 21 can be sprayed into the coal carried by the vehicle running in the space below the support arm 12 through the spray pipe 241. When the speed measuring assembly detects that the running speed of the vehicle increases, the controller controls the variable frequency water pump 23 to increase the running power, so that the flow rate of the spray structure 24 in a unit time can adapt to the increase of the running speed of the vehicle. However, the flow rate of the spray structure 24 in a unit time is difficult to meet the demand in a delay time required for the flow rate of the spray structure 24 in a unit time to increase to adapt to the increase of the running speed of the vehicle. The booster assembly 242 can increase the hydraulic pressure in the spray pipe 241 in the delay time, so as to increase the flow rate of the liquid sprayed from the spray pipe 241 in a unit time, and thus the flow rate of the liquid sprayed from the spray pipe 241 in the delay time can adapt to the increase of the running speed of the vehicle, and the spraying effect is better.

The structure is simple, and the operation is convenient.

[0038] In an embodiment, the booster assembly 242 further comprises a pressure sensor. The pressure sensor is arranged in the spray pipe 241.

[0039] Further, the pressure sensor is arranged in the spray pipe 241. The pressure sensor can monitor the hydraulic pressure in the spray pipe 241. The controller can control the micro water pump 2422 in real time according to the change of the hydraulic pressure in the spray pipe 241, so as to realize the self-adaptive adjustment of the hydraulic pressure in the spray pipe 241.

[0040] It should be noted that the interaction among the pressure sensor, the micro water pump 2422 and the controller adopts the prior art.

[0041] In an embodiment, a first one-way valve is arranged on the spray pipe 241, and a second one-way valve is arranged on the output end of the micro water pump 2422.

In addition, the output end of the micro water pump 2422 is also provided with a second one-way valve, and the flow direction of the second one-way valve is from the liquid storage pipe 21 to the spray pipe 241. By the second one-way valve, the liquid in the spray pipe 241 can be prevented from flowing back into the variable pipe 2421, so as to ensure the reliability of the variable pipe 2421 and the micro water pump 2422 for pressurizing the spray pipe 241.

[0043] In an embodiment, the spray pipe 241 is arranged vertically, the upper end of the spray pipe 241 is communicated with the liquid storage pipe 21, and the lower end of the spray pipe 241 is provided with a spray head 243.

[0046] Specifically, by the backflow pipe, the unused liquid can be recycled and re-supplied to the liquid storage tank 22, so as to avoid waste of the liquid. In addition, the backflow pipe can be used as a regulating channel of system pressure. In the case that the hydraulic pressure in the liquid storage pipe 21 is too high, by the control of the electrically controlled valve, the excess liquid can be backflowed to the liquid storage tank 22, so as to maintain the stability of the hydraulic pressure in the liquid storage pipe 21.
