Abstract

The invention discloses a liquid nitrogen storage system which comprises a plurality of liquid nitrogen tanks, an automatic storing and taking mechanism and a translation mechanism. Each liquid nitrogen tank is provided with a storing and taking port, each storing and taking port is provided with a tank cover capable of being opened and closed, and each liquid nitrogen tank is further provided with a cover opening and closing assembly used for opening and closing the corresponding tank cover; the automatic storing and taking mechanism is provided with a movable clamp, the clamp is used for forming a first low-temperature storage area after refrigeration, the clamp is further used for clamping and transferring objects taken out of the liquid nitrogen tanks or objects to be stored in the liquid nitrogen tanks, and the objects are made to be located in the first low-temperature storage area in the transferring process; and the translation mechanism is used for driving the automatic storing and taking mechanism to move to the appointed liquid nitrogen tank. In the process that the clamp clamps and transfers the objects, the objects are located in the low-temperature storage area formedby the clamp to keep low-temperature storage, so that the influence of room-temperature environment temperature is reduced, and low-temperature storing and taking in the whole process are achieved toimprove transportation reliability in the transferring process.

Description

technical field [0001] The invention belongs to the technical field of liquid nitrogen storage, and in particular relates to a liquid nitrogen storage system. Background technique [0002] At present, liquid nitrogen tanks are mainly used in the field of medical equipment for low-temperature preservation of biological samples such as blood and stem cells. Freezing boxes containing samples. In the actual use process, the access operation for samples is usually realized with the turnover bucket, and liquid nitrogen is also added in the turnover bucket. For transshipment. After the sample is taken out of the liquid nitrogen tank or the turnover bucket through the clamp, the sample will be exposed to room temperature, which will cause the temperature of the sample to rise and affect the activity of the sample. How to design a whole-process cryogenic access technology to ensure sample activity is the technical problem to be solved by the present invention. Contents of the in...
