The cross section of the sliding block 8 is larger than the cross section of the slide rail 15. A sliding structure is formed between the sliding block 8 and the slide rail 15. Two groups of second telescopic cylinders 7 are provided. The two groups of second telescopic cylinders 7 are symmetrically distributed about the central axis of the net frame 5, and can steadily push the bottom net plate 18 hingedly installed at the bottom end of the net frame 5 to move and open. The size of the coolant tank 10 is larger than that of the net frame 5. The coolant tank 10 and the net frame 5 are matched, so that the net frame 5 is placed in the coolant tank 10 as a whole for cooling.

[0024] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the second telescopic cylinder 7 is started to push the bottom mesh plate 18 downward. During the pushing process of the second telescopic cylinder 7, the sliding block 8 hinged at the bottom end of the second telescopic cylinder 7 will slide on the outer wall of the slide rail 15 to assist the tilting of the bottom mesh plate 18 to open the mesh frame 5, thereby facilitating the discharge of the cooled transmission shaft.

[0025] Embodiment 2: Electric guide rails 2 are installed at both ends of the top of the cooling box 1, a connecting plate 3 is fixed to the bottom of the cooling box 1, first telescopic cylinders 4 are installed on both sides of the bottom of the connecting plate 3, and the bottom of the first telescopic cylinder 4 is fixed to the top of the net frame 5. Four groups of first telescopic cylinders 4 are provided, and the four groups of first telescopic cylinders 4 are symmetrically distributed about the central axis of the connecting plate 3.

After cooling, the first telescopic cylinder 4 is started to pull the screen frame 5 to move upward to separate from the coolant. When there is no coolant dripping, the electric guide rail 2 is started again to pull the screen frame 5 to the other side of the cooling box body 1, and then the second telescopic cylinder 7 is started to push the bottom screen plate 18 to move downward to open one side of the bottom of the screen frame 5, so that the transmission shaft inside the screen frame 5 falls from the opening into the corresponding container for installation, and then the container is moved to complete the unloading of the transmission shaft.
