This spray dust removal method is to manually drive the vehicle and judge whether spray dust removal is needed based on sensory perception, or spray dust removal is performed periodically. The problems with the above methods are: First, in some places prone to dust, there are no motor vehicle roads or motor vehicles are inconvenient to pass, so that spray dust removal cannot reach the core pollution area and the dust removal efficiency is low; Second, when dust occurs, the notification of the vehicle to the scene is not timely enough, and the dust removal timeliness is poor. When the dust removal vehicle arrives at the designated location, the pollution peak may have passed and the dust has spread; Third, it relies on manually controlled equipment for spraying, and the degree of automation is low.

The track 3 is a double track, and the double tracks are arranged in parallel. The track 3 can be set on the ground or erected in the air through a bracket. The dust monitor 4 can use the VEMSEERS485 series dust sensor.

[0023] The closed-loop track should be set up in a manner that does not interfere with the normal production of the factory and the passage of other vehicles and personnel. When set up around the factory, it generally will not intersect with other roads in the factory. In this case, Track 3 can be set on the ground or erected in the air through a bracket; if set up in a place prone to dust, Track 3 may intersect with other roads in the factory. In this case, Track 3 can be erected in the air through a bracket.

[0024] The rail vehicle 2 is composed of a vehicle body 2-1 and a travel assembly; the travel assembly includes a travel wheel 2-2, a guide wheel 2-3, and an axle 2-4; the travel wheel 2-2 is arranged at both ends of the axle 2-4, and is in rolling contact with the upper end surface of the track 3; the guide wheel 2-3 is arranged horizontally through a bracket connected to the vehicle body 2-1, and is in rolling contact with the outer side surface of the track 3; the two ends of the axle 2-4 are installed in the axle seat below the vehicle body 2-1. A power supply assembly is arranged in the vehicle body 2-1, and the output of the power supply assembly is connected to the drive motor 2-5, the speed change gear box 2-6, and the driving gear 2-7 in sequence. The driving gear 2-7 is meshed with the passive gear 2-8, and the passive gear 2-8 is installed in the middle of the axle 2-4; the power supply assembly is a generator or a battery pack. The travel wheel 2-2 and the guide wheel 2-3 move in the same direction. When the power component uses a generator, a DC generator or an AC generator can be used, and the corresponding subsequent drive motor 2-5 also uses a corresponding DC or AC motor. When a DC motor is selected, the output of the drive motor 2-5 can be directly connected to the driving gear 2-7, and the speed of the rail car 2 can be controlled by the speed of the DC motor. When the power component uses a battery pack, a lithium iron phosphate battery pack can be used.

[0025] In order to make dust suppression more efficient and quick, multiple rail cars 2 can be set on the track 3. In order to avoid collision of rail cars 2, the following scheme can be adopted: the number of rail cars 2 is at least 2, and all rail cars 2 circulate in the same direction on the track 3; a laser distance sensor 2-9 is set at the front of the body 2-1 of each rail car 2, and the output signal of the laser distance sensor 2-9 is connected to other input terminals of the CPU, such as P0.1. The laser distance sensor 2-9 can be selected from the Ferris MyAntennaL1-40 model, and the range fully meets the needs.

[0026] The fog cannon can adopt the following structure: the fog cannon 1 is composed of a wind tube 1-1, an axial flow fan 1-3, and a nozzle 1-2; the wind tube 1-1 is a two-stage structure, which is formed by connecting a straight wind tube and a conical wind tube, and 1-2 axial flow fans 1-3 are provided; the nozzle 1-2 is provided in the conical wind tube, and an accelerating electrode 1-4 is provided in the conical wind tube in the water outlet direction of the nozzle 1-2; the nozzle 1-2 is connected to a high-pressure water pump and a high-pressure air pump provided on the vehicle body 2-1 through a water pipe and an air pipe respectively, and the high-pressure water pump is connected to a water tank provided in the vehicle body 2-1. The accelerating electrode 1-4 can be provided in 1-3 groups.

[0027] In the mist cannon of this structure, the nozzle 1-2 is inside the wind tube 1-1, so that the mist droplets sprayed by the nozzle 1-2 can continue to be accelerated by the strong wind in the wind tube, so that the mist droplets can be discharged from the tube faster. At the same time, under the action of the accelerating electrode 1-4 in the wind tube, the mist droplets can not only be further accelerated, but also charged, so that the mist droplets repel each other, prevent the mist droplets from condensing, and keep the mist droplet particle size to a minimum, so as to facilitate more effective dust collection.

[0028] The specific connection mode of the output of the above-mentioned CPU is as follows: the output end of the CPU is respectively connected to the base of the transistor amplifier circuit, and then connected to the control relay through the collector or emitter of the transistor, and the relay is respectively connected to the control drive motor 2-5, the accelerating electrode 1-4, the high-pressure water pump, the high-pressure air pump, and the axial flow fan 1-3. For example, the output end of P1.0 is connected to the control drive motor 2-5 through the first transistor T1 and the first relay J1, and P1.1, P1.2, P1.3, and P1.4 are respectively connected to the control accelerating electrode 1-4, the high-pressure water pump, the high-pressure air pump, and the axial flow fan 1-3 in the same way. The CPU uses the C8051F340 series chip, including 4 16-bit counters / timers, and the specific 8051F340-GQR model of SILICON LABS brand can be selected, and the number of its input / output terminals is 40, which can fully meet the needs.

[0029] The above-mentioned rail vehicle 2 that automatically moves on the track 3 by relying on electric drive can complete automatic cruising on the track 3 without relying on human intervention. During the cruising process, when the dust monitor 4 detects the presence of dust, the CPU controls the drive motor 2-5 to stop, the rail vehicle 2 stops, the CPU controls the acceleration electrode 1-4, the high-pressure water pump, the high-pressure air pump, and the axial flow fan 1-3 to start, and the fog cannon 1 starts to work for dust suppression. During this period, if a subsequent rail vehicle 2 moves here, the laser ranging sensor 2-9 on the subsequent rail vehicle 2 can detect that the distance with the front rail vehicle 2 is getting closer and closer. When the distance reaches 3-5 meters, the subsequent rail vehicle 2 stops moving forward, the fog cannon starts, and joins the dust suppression operation. After the dust suppression operation is completed, the front rail vehicle 2 starts first, and the laser ranging sensor 2-9 on the subsequent rail vehicle 2 detects that the distance is greater than 50 meters or no signal is detected, and then moves forward.
