Description

Technical Field

[0001] The utility model relates to the technical field of sample storage, in particular to a cryogenic sample storage device. Background Art

[0002] Most of the currently used sample storage devices adopt fixed lifting storage. With this method, the storage capacity is small, and the basket needs to be lifted to the upper operation cabin to access the samples. After the access is completed, it is placed in the refrigerator equipment for freezing. This extraction method requires lifting the entire set of baskets, which will make the sample boxes on the baskets in a non-frozen state, which is not conducive to the preservation of samples. Moreover, when picking sample tubes, frost is likely to occur, which is not conducive to the picking work. There are also some cryogenic storage devices with a scraping machine tube picking mechanism inside. The scraping machine tube picking mechanism is in a cryogenic state for a long time, which is likely to affect the accuracy of accurately selecting the plate rack / samples, will cause extremely serious impacts on the safety of samples, and is difficult to repair. Therefore, the inventor designed a cryogenic sample storage device. Summary of the Utility Model

[0105] Preferably, the rotating frame driving member 112 can drive the storage rotating frame 111 to rotate by using a motor plus gear meshing.

[0106] By rotating the storage rotating frame 111, each layer and each column of the storage rotating frame 111 can store sample boxes.

[0107] Furthermore, multiple groups of storage slots 113 are provided on the storage rotating frame 111, and the storage slots 113 can store sample boxes.

[0108] Furthermore, a dehumidifying member 3 is provided in the middle of the storage rotating frame 111. The dehumidifying member 3 can absorb the cold source in the storage compartment 1 into the operation compartment 2, and the dehumidifying member 3 can dehumidify the sample boxes in the operation compartment 2.

[0109] Furthermore, a ventilation device 8 is also provided on the maintenance door mechanism 15. One end of the ventilation device 8 is connected to the operation compartment 2, and the other end exchanges air with the external air.

[0110] Sample extraction process: It works through the transfer and sealing mechanism 5. The vertical sealing door 51 can be lifted. Then, the transfer component 41 drives the sample box to dock with the operation cabin 2. The sample box shoveling mechanism 21 puts the sample box on the transfer component 41 onto the operation table 222. Then, the extraction channel door mechanism 66 rotates by a certain angle to fully expose the extraction channel. The sample box shoveling mechanism 21 passes through the extraction channel to shovel the sample box on the storage structure member 11 and transfers the sample box to the operation table 222. At the same time, the dehumidification component 3 transports the cold source in the storage cabin 1 into the operation cabin 2 to dehumidify the sample box in the operation cabin 2, preventing the sample box and the samples in it from frosting. The sample tube picking mechanism 22 picks and transfers the sample tubes in the sample box. After picking, the sample box shoveling mechanism 21 puts the picked sample box onto the transfer component 41. The un-picked sample box is still put into the storage structure member 11 through the sample box shoveling mechanism 21 for ultra-low temperature freezing. The transfer component 41 horizontally moves the picked sample box to the initial position. At the same time, the extraction channel door mechanism 66 closes the extraction channel. The vertical sealing door 51 moves downward to close the channel from the operation cabin 2 to the transfer and scanning mechanism 4. The transfer component 41 transports the sample box to the lower part of the second access channel. The access and exit scanning is performed using the scanning component 42. The second channel door mechanism 9 horizontally moves and opens. The sample box on the transfer component 41 can be taken by manual and the second access channel is closed.

[0111] In summary, in the present utility model, by arranging the rotatable storage structure member 11 in the storage cabin 1, the storage capacity can be increased. And the sample box shoveling mechanism 21 and the sample tube picking mechanism 22 are arranged in the operation cabin, so that they are prevented from being in the ultra-low temperature freezing state for a long time, thus avoiding the reduction of the accuracy of picking and shoveling. By arranging the dehumidification component 3, the sample box in the operation cabin 2 can be dehumidified, which can avoid frosting during the picking process and thus affect the picking process. By arranging the transfer and scanning mechanism 4, the quick scanning and transfer of the sample box can be realized, improving the work efficiency. By arranging the maintenance door mechanism 15, it can be quickly opened for the maintenance of the interior of the storage cabin 1.
