The first storage section 200 is arranged in the accommodating chamber 110. The first storage section 200 is composed of a plurality of first freezing racks 210. Each first freezing rack 210 is used to store biological samples. The plurality of first freezing racks 210 form a first circular array. The plurality of first freezing racks 210 are configured to be rotatable around the center of the first circular array, and the distance between any two adjacent first freezing racks 210 among the plurality of first freezing racks 210 is less than the width of the first freezing rack 210 (the distance between any two adjacent first freezing racks 210 among the plurality of first freezing racks 210 is less than the width of the first freezing rack 210, indicating that the distance between any two adjacent first freezing racks 210 at least at one point in the radial direction of the first circular array is less than the width of the first freezing rack 210 at this point in the radial direction of the first circular array, that is, another first freezing rack 210 cannot be arranged at this distance, thereby improving the storage density).

[0027] The second storage section 300 is disposed in the accommodating chamber 110 and is located above the first storage section 200. The second storage section 300 is composed of a plurality of second freezing racks 310. Each second freezing rack 310 is used to store biological samples. The plurality of second freezing racks 310 form a second circumferential array. The plurality of second freezing racks 310 are configured to be rotatable around the center of the second circumferential array. At least one rack retrieval area 320 is formed in the second storage section 300. The rack retrieval area 320 is an area between two adjacent second freezing racks 310 whose spacing distance is greater than or equal to the width of the first freezing rack 210 (the rack retrieval area 320 is an area between two adjacent second freezing racks 310 whose spacing distance is greater than or equal to the width of the first freezing rack 210, indicating that the spacing distance of any point of the rack retrieval area 320 in the radial direction of the second circumferential array is greater than or equal to the width of the first freezing rack 210 in the radial direction of the second circumferential array, thereby, the first freezing rack 210 can be stored in or taken out through the rack retrieval area 320).

[0028] The present application sets up upper and lower layered freezing racks in the accommodating chamber 110, so that each layer of the freezing racks does not need to be set too high. When extracting the freezing racks to access biological samples, there is no need to lift the freezing racks to a too high position, which is convenient to use.

[0029] In some embodiments, the biological sample storage device 10 may further include a first drive device and a second drive device. The first drive device is used to drive the plurality of first cryopreservation racks 210 to rotate with the center of the first circular array as the rotation center; the second drive device is used to drive the plurality of second cryopreservation racks 310 to rotate with the center of the second circular array as the rotation center. Thus, the automation level is improved. In other embodiments, the plurality of first cryopreservation racks 210 and / or the plurality of second cryopreservation racks 310 may be rotated manually.

[0030] The biological sample storage device 10 may also include a third driving device, which is used to drive the multiple first freezing racks 210 to rotate with the center of the first circular array as the rotation center, and / or, to drive the multiple second freezing racks 310 to rotate with the center of the second circular array as the rotation center. In this way, costs can be saved. When the third driving device is used to drive the multiple first freezing racks 210 to rotate with the center of the first circular array as the rotation center, and, to drive the multiple second freezing racks 310 to rotate with the center of the second circular array as the rotation center, a clutch can be set, and the clutch can move up and down, and the up and down movement of the clutch can correspond to different gears, one of which corresponds to the multiple first freezing racks 210, and the other corresponds to the multiple second freezing racks 310.

[0031] In some embodiments, the biological sample storage device 10 further includes a retrieval device, which is disposed above the second storage unit 300 and is used to access the second freezing rack 310 or to access the first freezing rack 210 through the rack area. Specifically, the retrieval device can be a manipulator, a hook, a clamp, etc., which can move up and down to lift the first freezing rack 210 or the second freezing rack 310, or put the lifted freezing rack back.

[0032] The placing and taking device may be located inside or outside the accommodating chamber 110. The placing and taking device located inside the accommodating chamber 110 can ensure the preservation effect of the biological sample, and the placing and taking device disposed outside the accommodating chamber 110 can avoid the volume of the chamber 100 being too large.

[0033] The first storage unit 200 also includes a first fixing device and a first rotating shaft. The first fixing device fixes the plurality of first freezing racks 210 to form a first circular array. The first rotating shaft is connected to the first fixing device and the first driving device. The first driving device is used to drive the first rotating shaft, so that the first rotating shaft drives the plurality of first freezing racks 210 to rotate with the center of the first circular array as the rotation center through the first fixing device. In other embodiments, the first freezing racks 210 may be matched by means of a snap connection, and the first driving device may drive one of the first freezing racks 210 to rotate.

[0034] The second storage unit 300 also includes a second fixing device and a second rotating shaft. The second fixing device fixes the plurality of second freezing racks 310 to form a second circular array. The second rotating shaft is connected to the second fixing device and the second driving device. The second driving device is used to drive the second rotating shaft, so that the second rotating shaft drives the plurality of second freezing racks 310 to rotate with the center of the second circular array as the rotation center through the second fixing device. In other embodiments, the second freezing racks 310 may be matched by means of a snap connection, and the second driving device may drive one of the second freezing racks 310 to rotate.

[0035] Preferably, the first freezing rack 210 is at the same height as the second freezing rack 310. Thus, the heights of the first freezing rack 210 and the second freezing rack 310 are not too high, thereby improving the user experience.

[0036] In some embodiments, the diameters of the first circumferential array and the second circumferential array are consistent, thereby ensuring space utilization when the diameters of the heights of the cavity 100 are consistent. And the number of the plurality of second freezing racks 310 is one less than the number of the plurality of first freezing racks 210, thereby increasing the storage density of the second storage unit 300.

[0037] In some embodiments, the cavity 100 is a liquid nitrogen tank, which is used to store biological samples at low temperatures using liquid nitrogen. Liquid nitrogen can ensure that the biological samples are at a relatively low temperature, thereby ensuring the storage effect of the biological samples.

[0038] The first drive device and / or the second drive device include a motor. The motor drive method has a simple structure and can directly drive the rotating shaft to rotate. In other embodiments, it can also be a cylinder, and the cylinder can be extended and retracted to drive the rack to move, and the rack drives the rotating shaft to rotate through the gear. Since the technology of realizing rotation by various drive devices is well known to those skilled in the art, it will not be described here. The third drive device can also include a motor.

[0039] The accommodating chamber 110 may have a top opening, and the biological sample storage device 10 further includes a cover for opening and closing the top opening, thereby preventing cold leakage and ensuring the storage effect of the biological sample.
