• the upper cabin is provided therein with an operation area;
• the operation area is provided with a rack gripping mechanism, a rack barcode scanning mechanism, a cryotube suction mechanism, and a cryotube barcode scanning mechanism, and is configured to retrieve and store samples from the liquid nitrogen storage tank in the upper cabin through the storage and retrieval channel;
• and the upper cabin is provided with a pressure relief member for automatically discharging a pressure of the upper cabin;
• wherein the pressure relief member comprises a squeezable pressure relief tube;
• and the squeezable pressure relief tube comprises a first end communicated with the operation area and a second end closed by an adjusting element, with a closing size adjusted by an adjusting bolt group;
• wherein the upper cabin comprises a cabin base plate and an outer cabin cover provided on the cabin base plate;
• the outer cabin cover comprises an operation chamber housing located above the storage and retrieval channel;
• and the pressure relief member is provided on the operation chamber housing;
• wherein the outer cabin cover further comprises an electrical control box housing provided side by side with the operation chamber housing on the cabin base plate and communicated with the operation chamber housing at a bottom;
• wherein the rack gripping mechanism, the rack barcode scanning mechanism, the cryotube suction mechanism, and the cryotube barcode scanning mechanism are provided in the operation area through a reference plate;
• the reference plate is located on the cabin base plate;
• and the reference plate and the cabin base plate are jointly provided with a storage and retrieval port corresponding to the storage and retrieval channel;
• and
• the rack gripping mechanism is located at a first side of the storage and retrieval port through a Y-axis moving mechanism;
• a second side of the storage and retrieval port is provided with the cryotube suction mechanism;
• and the rack barcode scanning mechanism and the cryotube barcode scanning mechanism are located at an end of the storage and retrieval port away from the electrical control box housing.
