the first step is as follows: firstly, moving the device to a construction site of a building engineering, enabling the four supporting legs 10 to be stably supported on the ground, then externally connecting a water guide hose at the bottom of the water distribution pipe 4, connecting the water guide hose to a water source, pumping water into the water guide hose by using a water pump, simultaneously connecting an air pump 23, an air blower 24 and a hydraulic cylinder 2 to a power supply, and starting the air blower 24 to blow air to one side of the water distribution pipe 4;

the second step is that: after the water pump pumps water flow into the water distribution pipe 4, the power of the water flow drives the propeller blades 14 to rotate, so that the first rotating rod 15, the second supporting rod 12 and the annular water guide pipe 6 are driven to rotate, and finally the water flow is sprayed out from the water spray head 7;

the third step: after being sprayed out from the water spray head 7, the water flow hits the arc-shaped water guide sheet 18, the arc-shaped water guide sheet 18 breaks the water flow into water mist to be sprayed, and in addition, after passing through the snake-shaped water guide groove 20, the water flow flows along the snake-shaped water guide groove 20, so that the arc-shaped water guide sheet 18 is driven to rotate along the second rotating rod 19;

the fourth step: in the process of water spraying and dust falling, water flow which is leaked at one side of the device falls into the water guide groove plate 3 and flows down along the water guide groove plate 3, meanwhile, the air pump 23 is started, air is blown to the air inlet pipe 22 by the air pump 23, the flowing water flow is blown up, the blown water flow floats into the air along the air flow blown by the air blower 24, and finally dust falling is finished;

the fifth step: in the process of water spraying and dust falling, the hydraulic cylinder 2 is started, the blast pipe 9 is driven by the hydraulic cylinder 2 to blow air in a vertical rotating mode, and the water distribution pipe 4 is used for spraying water in a vertical rotating mode.

The control mode of the invention is controlled by a controller, the control circuit of the controller can be realized by simple programming of a person skilled in the art, the supply of the power supply also belongs to the common knowledge in the field, and the invention is mainly used for protecting mechanical devices, so the control mode and the circuit connection are not explained in detail in the invention.

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.
