The pressing column 27 passes through the movable base 49, the load-bearing block 28 and the rebound base 29 and is movably connected to the slide column 20.

When the second spring 39 rebounds, the spray rack 42 rebounds to the initial position and the active card 41 collides with the active card 41 after the extrusion of the second spring 39 is released. Therefore, the spray rack 42 vibrates after colliding with the active card 41 due to the rebound of the second spring 39. The vibration of the spray rack 42 will vibrate and clean the scale and dust attached to the nozzle, thereby solving the nozzle clogging caused by dust and scale and improving the service life of the equipment.

The fan-shaped movement of the spray rack 42 will drive the nozzle 43 to perform fan-shaped up and down spraying. When the rebound magazine 30 rebounds, it will drive the movable base 49 to rebound. Through continuous up and down fan-shaped reciprocating opening and closing spraying, the spraying mode is constantly changing. When opening from bottom to top, a throwing force is applied to the spray to expand the spraying range. At the same time, when pulled down, the spray will continuously collide and merge to reduce dust in low places.

[0021] Working principle: Step 1: Workers install the equipment on the tower, connect the water pipe to the equipment, then connect the equipped high-pressure pump to the pipeline, debug the equipment to discharge water, and then connect the quick-release interface on the transmission column 7 to complete the preparation of the equipment.

[0022] Step 2: When the tower is in operation, the wind will drive the fan blades 5 to rotate, and the fan blades 5 will drive the transmission column 7 to rotate. The rotation of the transmission column 7 will drive the spray fan 22 to rotate, so as to avoid the high-pressure spray in the air can only be changed by the tower. The transmission gear 13 is fixedly sleeved on the transmission column 7, and the transmission column 7 drives the transmission gear 13 to rotate. The transmission gear 13 drives the first gear 11, the second gear 12 and the third gear 14 to rotate, and at the same time drives the inner gear ring 15 to rotate. A rotating slide groove is provided inside the protective shell 1, and the inner gear ring 15 rotates in the slide groove, so as to avoid the loss of wind transmission energy and transmit the components in the equipment more stably and accurately.

[0023] The third step: the rotation of the inner gear ring 15 drives the rotating base 17 to rotate, and the rotation of the rotating base 17 drives the slide column 20 to rotate. The slide column 20 on the slide column 20 drives the pulley 36 to pull down, so that the rebound chamber 30 moves downward, and the downward movement of the rebound chamber 30 drives the pressing column 27 to move downward, and the pressing column 27 squeezes the first spring 38 and the extrusion round block 40. When the slide column 20 drives the pulley 36 to pull down and reach the rebound groove on the arc groove 21, the first spring 38 and the extrusion round block 40 rebound and drive the rebound chamber 30 to reset. The downward pulling of the rebound chamber 30 drives the movable base 49 to pull down, and the downward pulling of the movable base 49 drives the movable arm 46 to perform a fan-shaped contraction movement downward, and the movable arm 46 pulls the spray rack 42 to perform a fan-shaped contraction movement. The spray rack 42 performs a fan-shaped movement and drives the nozzle 43 to spray up and down in a fan shape. When the rebound chamber 30 rebounds, it drives the movable base 49 to rebound for reset spraying.

[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
