Initially, the sealing blocks 18 are all in contact with the inner walls of the chambers 3 to block the slot ports. After stopping ventilation and keeping the heat pipe rotor 4 still rotating, the driving motor 16 is started, which drives the bidirectional screw 15 to rotate, and then drives the connecting rods 13 at both ends to move towards each other along the slide rails 14, and further drives the insertion blocks 12 and the water passing plates 17 to move towards each other until the nozzles 19 are all moved above the heat pipe rotor 4. The first pump body 21 is started, and the water in the water tank 20 is conveyed through the first delivery pipe 22 into the corresponding water passing plates 17, and finally sprayed out through the nozzles 19 to wash the heat pipe rotor 4 and wash away the dust attached to the surface. The control valve 9 is opened, and the flushed sewage flows along the second pipe 6 into the ventilation pipe 7 and is discharged through the drain hopper 8, and flows into the recovery tank 10 after being filtered by the filter tank 11. The second pump body 23 is started, and the filtered water in the recovery tank 10 can be conveyed through the second delivery pipe 24 into the water tank 20 for recycling, saving water resources. After cleaning, the driving motor 16 is started in reverse to drive the bidirectional screw 15 to rotate in reverse, thereby driving the connecting rods 13, the insertion blocks 12, and the water passing plates 17 to move in the opposite direction, so as to move the nozzles 19 out of the chambers 3 and drive the sealing blocks 18 to re-abut against the inner walls of the chambers 3.
