[0045] As Figure 7 and Figure 8 shown, the output end of the water pump 707 is fixedly communicated with a conveying pipe 717, the conveying pipe 717 is movably penetrated through the dust shell 4 away from the water pump 707 and is communicated with the inside of the U-shaped pipe 713, the input end of the water pump 707 is communicated with the inside of the water tank 714 through a pipeline, through the setting of the conveying pipe 717, when the water pump 707 works, the water in the water tank 714 can be pumped out and conveyed to the U-shaped pipe 713 through the conveying pipe 717, so as to be conveniently distributed to the atomizing nozzle 706.

[0047] The use method and working principle of the device: in the preparation stage, the device is moved to the mine and located at a suitable ventilation position, according to the actual operation demand of the mine, the related parameter threshold values of ventilation are set through the PLC controller 5, for example, when the air quality deteriorates to a certain degree, the ventilation volume is increased, the related parameter threshold values of dust falling are set through the dust detector 708, for example, when the dust content reaches a certain value, the dust falling operation is performed, etc., then the water level of the water tank 714 is checked by unscrewing the sealing cover 716 at the top of the water inlet pipe 715, if the water level is insufficient, the water source is connected for water replenishment, after the water replenishment is completed, the sealing cover 716 is tightened to prevent dust and impurities from entering, then the hydraulic cylinder 201 is started through the PLC controller 5, the hydraulic rod 202 of the hydraulic cylinder 201 is extended and retracted to drive the fixed table 203 to move up and down, so as to move the ventilation shell 3 and the dust shell 4 to a suitable operation height.

[0048] In the ventilation stage, the speed regulating motor 602 is started by the PLC controller 5, the first rotating shaft 603 is driven to rotate by the speed regulating motor 602, the exhaust fan blade 604 is driven to rotate by the first rotating shaft 603, the rotating exhaust fan blade 604 extracts and discharges the air in the mine to the outside, and the air quality sensor 605 monitors the air quality of the surrounding environment in real time. When the air quality sensor 605 detects that the air quality related parameter threshold decreases to the preset value, the air quality sensor 605 transmits a signal to the PLC controller 5, the PLC controller 5 receives the signal and sends an instruction to the speed regulating motor 602, the speed regulating motor 602 increases the rotating speed to accelerate the air circulation in the ventilation shell 3. When the air quality sensor 605 detects that the air quality related parameter threshold increases to the preset value, the speed regulating motor 602 reduces the rotating speed according to the instruction of the PLC controller 5 to save energy.

[0049] In the dust reduction stage, the dust content in the surrounding environment is detected by the dust detector 708. When the dust detector 708 detects that the dust content in the surrounding environment is too high, the dust detector 708 transmits a signal to the PLC controller 5. The PLC controller 5 receives the signal and controls the water pump 707 and the driving motor 702 to start working. The water pump 707 pumps water from the water tank 714 through the pipeline, and then delivers the water to the U-shaped pipe 713 in the dust reduction shell 4 through the delivery pipe 717. At the same time, the driving motor 702 drives the second rotating shaft 703 to rotate, the blowing fan blade 704 on the second rotating shaft 703 starts to rotate to generate airflow, the second gear 712 on the outer surface of the second rotating shaft 703 meshes with the first gear 711 on the outer surface of the connecting pipe 710 to drive the connecting pipe 710 to rotate, the connecting pipe 710 drives the square pipe 705 and the atomizing nozzle 706 to rotate, the water in the U-shaped pipe 713 flows into the connecting pipe 710 and then enters the square pipe 705 and is sprayed out of the atomizing nozzle 706. Under the action of the airflow generated by the blowing fan blade 704, the atomized water mist is uniformly blown out, the water mist can absorb the dust in the air, so that the dust moves downward with the water mist, and the air containing the dust can be extracted by the ventilation mechanism 6 and discharged to the outside, thereby reducing the dust content in the mine. When the dust content decreases to the set safety range, the PLC controller 5 controls the water pump 707 and the driving motor 702 to stop working.
