However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0059] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example

The transport component 3 in the storage cabin 1 can receive the transfer tank and move the transfer tank to the side of the target storage tank 4. The biological sample in the transfer tank can be grabbed into the storage tank 4 by the mobile grabbing component 2, and the biological sample in the storage tank 4 can also be grabbed into the transfer tank. A large number of biological samples can be stored through the storage turntable 5.

[0061] The storage compartment 1 is equipped with a mobile grabbing assembly 2, a transport assembly 3, and a storage tank 4. The transport assembly 3 can receive the transfer tank through the access channel and move it to the side of the target storage tank 4. The mobile grabbing assembly 2 can access the storage tank 4 and the transfer tank for biological samples.

By setting multiple groups of storage turntables 5 in the storage tank 4, more biological samples can be stored. Since the storage turntable 5 is set to rotate in the storage tank 4, when it is necessary to extract or store the target biological sample in the storage turntable 5, the storage turntable 5 is rotated to rotate the target sample tube to the extractable position for extraction; there is no need to set up an additional extraction channel , and there is no need to set up multiple extraction ports, which not only makes the structure compact and stable, but also makes it possible to reduce the cost of liquid nitrogen and enhance the cooling effect when using liquid nitrogen to refrigerate the storage tank. The reduction of extraction ports also greatly ensures the impact of temperature during extraction. The structure of the sample storage turntable 5 is more stable and the transmission efficiency is more reliable. The biological samples in this device are in a cold chain state throughout the process, which ensures the activity of the biological samples. The transport component 3 can be used to connect multiple groups of storage tanks 4, which greatly improves the storage efficiency. The mobile grabbing component 2 is used to realize the storage and retrieval of biological samples and the picking of tubes. This device greatly improves work efficiency. Example
