[0002] Bull sperm storage devices are key equipment used in the livestock industry to store and protect bull sperm. Among these devices, liquid nitrogen tanks are widely used due to their ability to provide an extremely low temperature environment. By utilizing the cryogenic properties of liquid nitrogen, liquid nitrogen tanks effectively inhibit biological activity, thereby extending the storage time of bull sperm and maintaining its activity.

[0003] However, in actual use, liquid nitrogen tanks also have some shortcomings. In particular, when taking out the thin tube containing bull sperm, it is usually necessary to open the lid of the liquid nitrogen tank. Due to the volatile properties of liquid nitrogen, this operation often leads to a large amount of liquid nitrogen waste, increasing operating costs.

[0004] Therefore, it is necessary to provide a new bull sperm storage device to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the present invention provides a bull sperm storage device that seals multiple placement slots through sealing gaskets, thereby preventing external air from entering the multiple placement slots to prevent the temperature of the air from affecting the temperature in the multiple placement slots, so that multiple capillaries containing bull sperm can be better stored in multiple placement slots in a low-temperature environment. The liquid nitrogen in the liquid nitrogen tank can cool the multiple placement slots. When it is necessary to take out the capillaries containing bull sperm, the annular plate needs to be rotated to drive the sealing gasket to move vertically, so that the sealing gasket releases the blockage of the multiple placement slots. When the annular plate is separated from the shell, the forward and reverse switch can be used to control the operation of the pushing mechanism, so that the pushing mechanism can quickly push the top ends of the multiple capillaries out of the multiple placement slots respectively, so that the operator can take out the multiple capillaries conveniently and quickly. In the process of taking out the multiple capillaries, since there is no need to open the cover body, the liquid nitrogen in the liquid nitrogen tank will not come into contact with the outside air, which can effectively prevent the waste of liquid nitrogen due to large-scale volatilization, which is beneficial to saving operating costs and has a better use effect.
