[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The atomization mechanism includes a connecting cover connected to the fan cover. A plurality of arm seats are slidably installed at equal angles on the outer side of the connecting cover. A rotating shaft is rotatably installed inside the arm seat. Rotating arms are symmetrically installed at both ends of the rotating shaft, and an adjusting plate seat is installed on the rotating arm. A connecting waterproof film is installed between adjacent adjusting plate seats. A support seat is installed on the inner side of the outer end of the adjusting plate seat, and an atomizing nozzle is installed on the support seat.

[0008] Preferably, support shafts are symmetrically installed on the outer side of the fan cover, and the support shafts and the U-shaped seat are connected by bearings. A first motor is installed on the U-shaped seat, and the output end of the first motor is connected to one of the support shafts.

[0009] Preferably, a first ring seat is installed on the connecting cover, a plurality of the arm seats are all connected to a second ring seat, a plurality of air cylinders are installed on the first ring seat, and the telescopic end of the air cylinder is connected to the first ring seat.

[0010] Preferably, a plurality of embedding grooves are equiangularly formed on the outer side of the connecting cover, racks are installed in the embedding grooves, a rotating gear is installed in the middle of the rotating shaft, and the rotating gear meshes with the racks.

[0011] Preferably, a plurality of arm grooves are equiangularly formed on the outer side of the connecting cover, and the arm grooves are correspondingly arranged with the rotating arms.

[0012] Preferably, a rotating gear is installed in the middle of the rotating shaft, and the rotating gear meshes with the racks.

[0013] Preferably, an annular pipe is installed on the fan cover, a plurality of connecting hoses are connected to the annular pipe, and the connecting hoses are connected to the atomizing nozzles.

[0014] Preferably, an inner cavity is formed in the adjusting plate seat, a rotating frame is rotatably installed in the inner cavity, a winding shaft is rotatably installed in the rotating frame, and the winding shaft is parallel to the side wall of the adjacent adjusting plate seat. A connecting waterproof film is wound on the winding shaft, and the connecting waterproof film is connected to the side wall of the adjacent adjusting plate seat.

[0015] Preferably, a second motor is installed on the adjusting plate seat, the output end of the second motor is connected to the top side of the inner end of the rotating frame, a third motor is installed at the outer end of the rotating frame, and the output end of the third motor is connected to the winding shaft.

[0016] A working method of a dust suppression fog cannon device, and the specific operation steps of the working method are as follows:

[0017] Step 1: Drive the U-shaped seat to rotate through the work of the electric rotating table, drive the fan cover to rotate through the work of the first motor, so as to realize the multi-angle adjustment of the fan cover. The annular pipe is connected to the water pump. Drive the blades to rotate through the work of the fan, introduce the external air of the device into the fan cover through the mesh cover, and flow to the air outlet of the atomizing mechanism through the flow dividing grid. When the water pump works, the water passes through the annular pipe and the connecting hose and then is sprayed out from the atomizing nozzles. At this time, the high-pressure air in the fan cover carries the atomized water sprayed out by the atomizing nozzles and sprays out together, combines with the dust in the external air and precipitates, so as to realize the dust suppression operation on the air.

[0018] Step 2: The atomization mechanism adjusts the diameter of the air outlet of the device. The air cylinder on the first ring seat drives the second ring seat to move. The second ring seat moves synchronously with the arm seat. When the arm seat moves, the rotating teeth on the rotating shaft rotate along the rack in the groove, thereby driving the adjusting plate seat to rotate around the rotating shaft. At the same time, during the rotation of the adjusting plate seat, the second motor on the adjusting plate seat drives the rotating frame to rotate, ensuring that the winding shaft in the rotating frame is always flush with the side wall of the adjacent adjusting plate seat. At the same time, the third motor drives the winding shaft to rotate to wind the connecting waterproof film, ensuring that the connecting waterproof film is always in a taut state when the adjusting plate seat rotates. At this time, the inner diameter of the combined structure of the adjusting plate seat and the connecting waterproof film is the diameter of the air outlet of the device. As the adjusting plate seat rotates, the diameter of the air outlet of the device is adjusted. When the diameter of the air outlet becomes smaller, the spraying distance of the atomized water vapor increases, and the spraying area of the atomized water vapor decreases. When the diameter of the air outlet becomes larger, the spraying distance of the atomized water vapor decreases, and the spraying area of the atomized water vapor expands.

[0019] The beneficial effects of the present invention are as follows: The movement of the arm seat is realized by the movement of the second ring seat. Through the cooperation of the rotating teeth and the rack, the rotation of the rotating arm and the adjusting plate seat is realized, and the preliminary adjustment of the diameter of the air outlet position of the device is realized. And when the adjusting plate seat rotates, by rotating the rotating frame and the winding shaft respectively, the adjustment of the connecting waterproof film is realized. The inner diameter of the combined structure after the adjustment of the adjusting plate seat and the connecting waterproof film is the diameter of the air outlet of the device. As the adjusting plate seat rotates, the diameter of the air outlet of the device is adjusted. When the diameter of the air outlet becomes smaller, the spraying distance of the atomized water vapor increases, and the spraying area of the atomized water vapor decreases. When the diameter of the air outlet becomes larger, the spraying distance of the atomized water vapor decreases, and the spraying area of the atomized water vapor expands. Thus, according to the pollution situation of the actual dust removal space, the flexible adjustment of the spraying distance and spraying range of the device is realized.

A connecting waterproof membrane 18 is installed between adjacent adjusting plate seats 16. A support seat 19 is installed on the inner side of the outer end of the adjusting plate seat 16. An atomizing nozzle 20 is installed on the support seat 19. A first ring seat 11 is installed on the connecting cover 10. A plurality of arm seats 14 are all connected to the second ring seat 12. A plurality of air cylinders 13 are installed on the first ring seat 11. The telescopic end of the air cylinder 13 is connected to the first ring seat 11.

And when the adjusting plate seat 16 rotates and adjusts, the connecting hoses 22 ensure that the atomizing nozzles 20 and the annular pipe 21 are always in a communicating state.
