Movement of the docking station 31 is powered by the provision of a first brake 33. By providing the first driving lever 32, the first driving lever 32 is fixedly connected to the docking station 31 and engaged with the first stopper 33. So that power is transmitted from the first stopper 33 to the docking station 31 to drive the docking station 31 to extend or retract the cabinet 1.

The meshing connection refers to a transmission relationship between two mechanical parts, and is also called meshing transmission.

The process that the docking mechanism 3 receives the liquid nitrogen tank is that after the AGV carrying the liquid nitrogen tank reaches the docking position, the docking mechanism 3 is controlled to extend out of the opening 11 of the box body 1 to be docked with the AGV. After the butt joint is completed, the second brake piece drives the conveying belt 34 to rotate synchronously with the belt of the AGV trolley, and the liquid nitrogen tank is transferred from the AGV trolley to the receiving surface of the conveying belt 34. After the liquid nitrogen tank reaches the receiving surface of the conveyor belt, the conveyor belt 34 stops the translational rotation, and the first stopper 33 drives the docking station 31 into the case 1. At this point, the translation mechanism 2 is controlled to start translational rotation, and the docking station 31 enters the cabinet 1 at the same speed as the translation mechanism 2 rotates translationally. Since the upper surface of the translation mechanism 2 and the upper surface of the docking station 31 are at the same level, the docking station 31 can transfer the liquid nitrogen tank to the translation mechanism 2.
