The number of the pushing grooves 1103 is multiple. After the cooling tower main body 1 is used for a period of time, the lock catch 1106 can be opened, and then the overhaul door 1105 is pulled out from the overhaul groove 1104. At this time, the rotating sleeve 1101 can be touched through the overhaul groove 1104, and the rotating sleeve 1101 is pushed to move to one side through the pushing groove 1103. The rotating sleeve 1101 can rotate under the support of the ball at the bottom end and the support ring 1102. When rotating, the conditions of different positions of the packing 10 can be completely viewed through the overhaul groove 1104, and maintenance can be carried out at the same time, so as to increase the service life of the packing 10 and enhance the processing effect.

[0029] During use, when the cooling tower is operating, the external hot water enters the connecting pipe 302 through the water inlet pipe 301, and enters the plurality of water distribution pipes 304 through the connecting pipe 302 and the plurality of hoses 303, and is sprayed out through the water distribution pipes 304. At this time, the control cylinder 308 operates. The internal technology of the cylinder 308 is the prior art.
