Referring to fig. 1 to 4, the present embodiment provides a method for spraying antifreeze on a coal car, which includes the steps of:
s1: receiving a position signal representing the position of the coal car and a speed signal representing the speed of the coal car;
s2: determining the arrival time of the coal car to the spraying area according to the position signal and the speed signal;
s3: before the arrival time, the spray head 124 is opened, and the vacuum feeder 113 is started;
s4: after the coal car is driven out of the spraying area, the control spray head 124 and the vacuum feeder 113 are closed.
The working principle of the coal car antifreeze spraying method is as follows:
according to the coal car antifreeze spraying method, the position and the running state of the coal car are monitored, so that the spray head 124 and the vacuum feeder 113 can be controlled according to the position of the coal car relative to a spraying area, and the antifreeze can be sprayed on the coal car; the mode of spraying the antifreeze can improve the coverage rate of the antifreeze in the coal car, thereby avoiding the phenomenon of car adhesion caused by freezing of coal at extremely cold temperature, improving the antifreeze effect, improving the efficiency of antifreeze operation, solving the problem of coal freezing and improving the transportation efficiency and antifreeze quality of railways.
First, when the nozzle 124 is opened and the vacuum feeder 113 is started, the position of the nozzle 124 and the vacuum feeder 113 may be adjusted; specifically, the model of the coal car entering the spraying area can be determined according to the running table of the number of cars, so that the spraying angle, the spraying amount and the size of the spraying area of the spray head 124 can be adjusted according to the specific model of the coal car, and the working state of the vacuum feeder 113 can be adjusted, so that the spraying quality of the antifreezing agent can be improved, and the antifreezing effect can be improved.
Secondly, in the spraying process, the method is used for spraying by taking a single coal saving car as a unit, namely, when it is monitored that one coal saving car runs to a spraying area, the method is started to be executed, and after the spraying of the coal saving car is finished, the control spray head 124 and the vacuum feeder 113 are closed until the next coal saving car is monitored to run to the spraying area after the coal saving car is monitored to run out of the spraying area; therefore, by the arrangement mode, the spraying suspension action exists between the two adjacent coal-saving cars, and the waste of the antifreeze can be avoided.
Further, in this embodiment, when the storage unit 112 includes a storage bin 114, the coal car antifreeze spraying method further includes the steps of:

until the residual amount of the antifreezing agent is greater than or equal to a second preset residual amount;

In this embodiment, when the stock unit 112 includes a plurality of bins 114, each bin 114 is provided with a level indicator, the coal car antifreeze spraying method further includes the following steps:
receiving the stock signals output by the plurality of level meters, and determining the residual amount of the antifreeze in all the storage bins 114 according to the stock signals;
when the residual amount of the antifreeze in the storage bin 114 with the inlet communicated with the discharge end of the feeding mechanism 110 is smaller than a first preset residual amount, controlling the feeding mechanism 110 to convey the antifreeze input from the feeding port to the storage bin 114; until the residual amount of the antifreezing agent is greater than or equal to a second preset residual amount;
when the residual amount of the antifreeze in the silo 114 with the inlet communicated with the outlet of the adjacent silo 114 is less than a first preset residual amount, conveying the antifreeze in the adjacent silo 114 to the silo 114; until the residual amount of the antifreezing agent is greater than or equal to a second preset residual amount;
the antifreezing agent comprises calcium chloride, and the first preset allowance is less than or equal to the second preset allowance.
It should be noted that, in this embodiment, the antifreeze is exemplified by calcium chloride, and in the spraying process, the antifreeze is a mixture of liquid and solid of calcium chloride, wherein the solid calcium chloride is in a solid particle shape, the solid particle in the antifreeze mixture sprayed on the coal car mainly covers the floor of the coal car, and the liquid calcium chloride sprayed on the car side adheres to the car side, so as to improve the antifreeze effect of the car of the coal car.

in order to improve the spraying efficiency, the position of the spray head 124 can be adjusted by adjusting the position of the lifting frame 122 relative to the base 121, so that the spraying area covered by the spray head 124 can be adjusted in such a way;
and because the feed mechanism 110 and the spraying mechanism 120 are electrically connected with the controller, therefore, the working states of the feed mechanism 110 and the spraying mechanism 120 are adjusted and controlled in the spraying process through the controller, so that the coverage rate of the antifreezing agent in the coal car can be improved, the phenomenon of car adhesion caused by freezing of coal at an extremely cold temperature can be avoided, the antifreezing effect can be improved, the antifreezing operation efficiency can be improved, the coal freezing phenomenon can be avoided, and the railway transportation efficiency and antifreezing quality can be improved.
