the dust concentration sensor 24 is activated and when the dust concentration in the air rises and is greater than the acceptable value defined by the dust concentration sensor 24, the dust concentration sensor 24 sends an alarm signal to the control room.

After receiving the alarm signal, an operator in the control room starts the water pump 6, so that the motor of the water pump 6 rotates forwards, water in the water tank 1 flows into the water pumping hose 4 through the first round hole of the water tank 1, and the water in the water pumping hose 4 enters the water pump 6 through the water inlet of the water pump 6.

The water that gets into water pump 6 obtains the pressurization to make water of water pump 6 obtain pressure and form the high pressure water, because the effect of pressure, the water in the water pump 6 moves towards in the pressurization inlet tube 5, and then makes water enter into spray pipe 8 through pressurization inlet tube 5 in, make spray pipe 8 inside obtain pressure.

The displacement pulley 18 pushes the pulling rope 26, so that the pulling rope 26 obtains thrust, and further, the pulling rope 26 moves in the direction of the thrust, so that the pulling rope 26 displaces, and further, the blocking cover 27 moves in the direction of the movement of the pulling rope 26, so that the fillet between the cover side wall 9 of the blocking cover 27 and the circular plane 28 leaves the water spray pipe 8, so that the blocking cover 27 does not block the water spray pipe 8, when the piston 21 moves to abut against the limit ring 31, the push rod 22 does not displace any more, so that the resultant force on the pulling rope 26 is zero, and further, the resultant force on the blocking cover 27 is zero, so that the blocking cover 27 is static.

Because of the effect of water pressure in the spray pipe 8, the slide 13 slides to the spray pipe 8 and is close to the one end of the blocking cover 27, make the shower nozzle 10 stretch out outside the spray pipe 8, make the slide 13 abut against the sealing strip 12 of the inner wall of the spray pipe 8, make the slide 13 seal with the spray pipe 8, and then make the shower nozzle 10 seal with the spray pipe 8, make water form after passing through the shower nozzle 10 and spout the fog and spout to the air, make the dust in fog and the air combine, the quality grow after the dust combines with water, and then make the dust gravity grow, thereby make the dust move towards the direction of gravity, and then make the dust drop to ground 7, make the dust no longer float in the air.

When the dust concentration in the air is reduced and the concentration is smaller than the qualified value defined by the dust concentration sensor 24, the dust concentration sensor 24 stops sending an alarm signal to the control room, an operator controls the water pump 6 to rotate reversely for 10 seconds and then turns off the water pump, so that the pressure in the water spray pipe 8 is reduced, the sliding plate 13 is not subjected to upward supporting force, the sliding plate 13 moves towards one end close to the ground 7 under the action of gravity, the spray head 10 is driven to move towards one end close to the ground 7, and the spray head 10 slides into the water spray pipe 8.

The pressure in the spray pipe 8 is reduced, so that the pressure in the spray pipe 8 is smaller than the pressure outside the spray pipe 8, the piston 21 in the thrust pipe 25 moves towards one end close to the ring 20, the piston 21 drives the push rod 22 to move towards one end of the thrust pipe 25 close to the ring 20, the push rod 22 drives the displacement pulley 18 to move towards one end of the thrust pipe 25 close to the ring 20, the thrust of the displacement pulley 18 acting on the pull rope 26 is reduced, the pull force of the pull rope 26 on the blocking cover 27 is reduced, the resultant force on the blocking cover 27 points to the direction of the blocking pipe orifice 33, the blocking cover 27 moves towards the resultant force direction, the round angle between the cover side wall 9 and the circular plane 28 is abutted to the spray pipe 8, and the blocking cover 27 blocks the spray pipe 8.
