At the same time, the cold storage battery 4 waiting for cold storage on the uppermost side of the first buffer 23 is pushed by the first push rod 2811 to enter the cold storage slide on the lowermost side of the heat exchanger 22, and the cold storage battery 4 which has completed cold storage and is originally located in the cold storage slide is pushed into the second buffer slide 241 on the uppermost side of the second buffer 24, so as to reach the state shown in fig. 6. Then, the piston rods of the first and

second drive cylinders

291 and 292 are simultaneously pushed out, and the first and

second push carriages

281 and 282 are pushed out to reach the state shown in fig. 20. The heat exchanger 22, the first buffer 23 and the second buffer 24 are then rotated by one station in the manner shown in figure 18, again reaching the condition shown in figure 21. Meanwhile, the servo motor 14 drives the cold accumulation thermal insulation box 3 to move backward by one station, so that the next cold discharge slideway 311 is aligned with the second buffer slideway 241 at the lowest side. Repeating the above operations until the cold accumulation batteries 4 in the cold accumulation insulation can 3 are completely replaced.

Further, as shown in fig. 6, 7 and 8, when the first driving cylinder 291 and the second driving cylinder 292 are retracted to the extreme positions, the inner end surface of the first push rod 2811 is flush with the left end surface of the heat exchanger 22, and the inner end surface of the second push rod 2821 is flush with the right end surface of the cold storage thermal insulation box 3.

Example two

The first buffer 23 and the second buffer 24 are rotatably connected to the main frame 21 through bearing assemblies, first driving cylinders 291 are respectively disposed on the main frame 21 at the front and rear sides of the first buffer 23, and second driving cylinders 292 are respectively disposed on the main frame 21 at the front and rear sides of the second buffer 24. The rest of the structure is the same as the first embodiment.
