The water pipe 6 is connected to a water collecting cylinder 13. A vent 18 is opened on the cooling tower 1. By starting the water tank 17, the spray water enters the water collecting cylinder 13 through the water pipe 6.

[0023] A plurality of fixed blocks 3 are installed in the cooling tower 1, and a convex plate 4 is connected to the top of the fixed block 3.

The convex plate 4 is connected to a plurality of loading frames 5. The loading frames 5 are provided with a plurality of circular holes. An action block 8 is connected to the output end of the driving motor 2, and the action block 8 is movably matched with the convex plate 4. A load-bearing frame 10 is fixed to the bottom end of the fixed block 3, and the driving motor 2 is connected to the load-bearing frame 10. When the spray water enters the water collecting cylinder 13, the cooling pipe 20 can be sprayed. During the spraying process, the driving motor 2 is driven to drive the action block 8 The action block 8 rotates and becomes elliptical. During the rotation of the action block 8, the convex plate 4 will be continuously touched. After the convex plate 4 is pushed by the action block 8, the tension spring 9 is stretched and deformed. After the action block 8 stops pushing the convex plate 4, the tension spring 9 is reset. The tension spring 9 pulls the convex plate 4 to move synchronously while resetting. Therefore, under the cooperation of the action block 8 and the tension spring 9, the convex plate 4 is made to reciprocate laterally. During the reciprocating motion, the convex plate 4 drives the loading frame 5 to move synchronously, so that the spray device installed on the loading frame 5 is moved, thereby spraying the cooling pipe 20 as a whole.
