[0025] Among them, a groove is opened on the lower surface of the I-beam base 1, and a dual-axis motor 5 is fixedly connected inside the groove, and threaded rods 7 are fixedly connected at both ends of the dual-axis motor 5. The two threaded rods 7 are respectively located inside the two slide grooves 6, and the internal thread block 8 is threadedly sleeved on the surface of the threaded rod 7. The dual-axis motor 5 drives the two threaded rods 7 to rotate, so that the internal thread block 8 can move on the surface of the threaded rod 7 and drive the heat dissipation fins 11 to move, so as to be clamped on the surface of the ladle body 4. Not only can different types of ladle bodies 4 be clamped, but also the heat generated by the ladle body 4 can be transferred to the heat dissipation fins 11, thereby increasing the heat dissipation area of ​​the ladle body 4.

[0026] Among them, vertical plates 12 are fixedly connected to both sides of the upper surface of the I-shaped base frame 1, and a sliding rod 10 is fixedly connected to the surface of the side of the movable plate 9 away from the heat dissipation fins 11.

Not only can different types of ladle bodies 4 be clamped, but also the heat generated by the ladle body 4 can be transferred to the heat dissipation fins 11, thereby increasing the heat dissipation area of ​​the ladle body 4. The water pump 20 is started to pump out the water in the liquid storage tank 14, and the water is pumped out from the transmission tank 14. The water pipe 19 is input into the watering pipe 18 and is sprinkled out from the watering pipe 18, which will wet the top of the wet curtain plate 16, thereby wetting the wet curtain plate 16.
