Because the tunnel is located underground, the air temperature in the tunnel is low, the air pressure difference exists between the inside and the outside of the tunnel due to the temperature difference between the inside and the outside of the tunnel, and the air flows rapidly due to the air pressure difference, so the air speed in the tunnel is high, when no wind exists in the tunnel, dust generated by construction cannot fly everywhere, when the wind blows in the tunnel, the air flow can blow the dust to fly around, and the air flow doped with the dust blows towards the air inlet cover 28 of the box body 1, the fan 5 is driven to rotate and enters the accelerating channel 9 with the small inner diameter through the installation groove 4, when the air flow enters the accelerating channel 9 with the small inner diameter from the installation groove 4 with the relatively large space, and according to the venturi effect, the air flow can obtain higher flow speed when passing through the accelerating channel 9.
When high-speed airflow flows through the accelerating channel 9, according to the Bernoulli principle, when the airflow is flowing at the same height, the flow speed is high, the pressure is low, namely, the pressure at the position, close to the pipe orifice at one end of the accelerating channel 9, of the water suction pipe 10 is reduced by the airflow flowing at the high speed, under the action of the air pressure, water flow in the water box 12 enters the accelerating channel 9 through the water suction pipe 10 and is sprayed out from the accelerating channel 9 together with the airflow flowing at the high speed, when the water flow flowing at the high speed passes through the mesh enclosure 11, the water flow becomes unstable under the action of inertia force, so that the water flow is cut and crushed into threads or strips by the mesh enclosure 11, and strong vibration is generated by relative movement with air, so that the action of the surface tension and the action of the viscosity force of the water flow is gradually weakened, the length of a liquid film is shortened, the shape is distorted, in conclusion, the box body 1 is filled with water vapor and dust-laden gas as the water vapor mixture is continuously sprayed from the accelerating channel 9.
Because the dust particles have small diameter and large surface area, the dust particles have certain hydrophilicity and adsorptivity, water vapor in the box body 1 can be condensed into small water drop-shaped suspended particles on the dust particles when floating, namely condensation nuclei, the condensation nuclei have large weight and can gradually fall on the bottom plate 18.
The rotating shaft 7 can drive the screw rod 15 to rotate through the synchronous belt in the rotating process, because the side wall of the movable plate 16 is attached to the inner wall of the mounting box 14, and the sections of the movable plate 16 and the mounting box 14 are both in a rectangular structure, the screw rod 15 cannot drive the movable plate 16 to rotate when rotating, so that the movable plate 16 can only move left and right along the screw rod 15, when the movable plate 16 moves left, the movable plate 16 can discharge the gas in the mounting box 14 into the two air bags 20 through the two connecting pipes 17, and inflate and expand the two air bags 20 to drive the two movable blocks 21 to approach each other, when the movable plate 16 moves right, the mounting box 14 can pump out the gas in the two air bags 20 to restore the original state, so that the two movable blocks 21 are far away from each other, based on the process, the two movable blocks 21 can continuously approach each other and keep away, in the process that two movable blocks 21 are close to each other, two scraping strips 22 can scrape dust on the bottom plate 18 into the collecting box 19, so that the bottom plate 18 is cleaned, and the dust on the bottom plate 18 can be uniformly treated in the later period of a worker.
Because the air outlet cover 2 is internally provided with the waterproof breathable film 26, the waterproof breathable film 26 is a novel high-molecular waterproof material, only gas is allowed to pass through, and liquid and solid substances can be limited to pass through, because only air without doped dust can be blown out from the air outlet cover 2 through the waterproof breathable film 26, along with the long-term use of the device, a certain amount of dust can be attached to the surface of the waterproof breathable film 26, when the left moving block 21 moves rightwards, the cleaning plate 27 can be driven to move downwards through the connecting rope 23, when the left moving block 21 moves leftwards, the cleaning plate 27 can move upwards under the elastic force of the spring, based on the process, along with the left-right movement of the left moving block 21, the cleaning plate 27 can continuously move upwards and downwards, and in the process that the cleaning sponge on the side wall of the cleaning plate 27 can continuously wipe, the dust attached to the surface of the waterproof breathable film 26 can be erased, and the waterproof breathable film 26 can be ensured to exert the normal effect.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
