[0017] A first motor 17 is fixed in the frame 3 and is coaxially fixedly connected to the hollow pipe 5.

[0018] In order to ensure the stability of the left-right sliding of the second base 14, guide rails 18 are fixed to the first base 12 and are located on the upper and lower sides of the screw rod 13, and the second base 14 slides along the guide rails 18 in the left-right direction.

[0019] In order to ensure the appropriate rotating speed of the screw rod 13, a second motor 19 is fixed to the first base 12 and is coaxially fixedly connected to the screw rod 13 through a speed reducer.

[0020] The storage barrel 15 contains corrosion-proof paint, a booster pump 20 is arranged on the storage barrel 15 and is communicated with the pipeline 16.

[0021] In order to maintain the balance of the trolley 9, a counterweight 21 is arranged on the trolley 9.

[0022] When this utility model is in use, if the inner wall of the cooling tower requires anti-corrosion treatment, the trolley 9 is moved to a suitable position outside the tower body 1, so that the hollow tube 5 is above the tower body 1. The hydraulic cylinder 10 is activated, and the hydraulic cylinder 10 controls the piston rod 11 to move downward. The piston rod 11 drives the first base 12, the second base 14, the first support rod 2, the frame 3, the cylinder 4, and the hollow tube 5 to move as a whole into the tower body 1. When the hollow tube 5 moves downward to a suitable height inside the tower body 1, the hydraulic cylinder 10 is closed, and the second motor 19 is turned on. The second motor 19 drives the lead screw 13 to rotate through the reducer. The lead screw 13 drives... The second base 14 slides left and right along the guide rail 18, thereby adjusting the distance between the first support rod 2 and the hollow tube 5 in the left and right directions within the tower body 1. When the hollow tube 5 is located in the middle position within the tower body 1, the second motor 19 is turned off, and the booster pump 20 is started. The pipeline 16 passes through the first base 12 and the second base 14, and finally connects to the cylinder 4. The booster pump 20 transports the anti-corrosion coating in the storage tank 15 to the inside of the cylinder 4 through the pipeline 16. The anti-corrosion coating inside the cylinder 4 enters the hollow tube 5 through the through hole 6, and is finally sprayed outward through the nozzle 8 and the spray plate 7. The spray plate 7 sprays the bottom of the cooling tower, and multiple spray plates spray outward. The first motor 17 is started, which drives the hollow tube 5 to rotate coaxially. The hollow tube 5 drives multiple nozzles 8 to rotate circumferentially, greatly increasing the spray area of ​​the nozzles 8, resulting in uniform spraying, high automation, and good spraying quality. During the rotation of the hollow tube 5, the cylinder 4 is fixedly connected to the frame 3, and the position of the cylinder 4 remains unchanged. A rotating sealing ring is installed between the cylinder 4 and the hollow tube 5 to ensure the sealing of the cylinder 4. The hollow tube 5 has multiple through holes 6 evenly distributed around its circumference, which are connected to the cylinder 4, so that anti-corrosion coating is always introduced into the hollow tube 5 during its rotation inside the cylinder 4. The coating enters through the through hole 6 to ensure the stability of the anti-corrosion coating delivery. The hydraulic cylinder 10 can be activated in real time according to the spraying needs to adjust the vertical height of the piston rod 11, thereby adjusting the lifting height of the hollow tube 5 in real time to ensure all-round anti-corrosion treatment of the inner wall of the cooling tower. The spraying range is wide. After the spraying is completed, the first motor 17 and the booster pump 20 are turned off, and the hydraulic cylinder 10 is activated. The hydraulic cylinder 10 drives the piston rod 11 to slide upward, so that the hollow tube 5 falls upward and falls off the tower body 1. When the hollow tube 5 is above the tower body 1, the hydraulic cylinder 10 is turned off, the trolley 9 is moved away from the cooling tower, and then the anti-corrosion treatment of the next cooling tower is carried out.
