Abstract

A low-temperature freezing device for fish sperms is disclosed. The device includes a foam heat-insulating box containing liquid nitrogen, a box cover at the top of the foam heat-insulating box, a storage box used for refrigerating fish sperms, a height adjusting gear, a temperature sensor and a digital thermometer. The storage box is put above the liquid nitrogen in the foam heat-insulating box.The height adjusting gear is connected to the storage box to adjust the height of the storage box relative to the liquid level of the liquid nitrogen. The temperature sensor is disposed at the bottomof the storage box, and is electrically connected to the digital thermometer. The liquid nitrogen used for freezing the fish sperms is disposed in the foam heat-insulating box, and the height of the storage box containing the fish sperms relative to the liquid surface of the liquid nitrogen is controlled by the height adjusting gear so as to control the freezing temperature of the fish sperms. Thedevice is simple in structure, easy to implement, and suitable for temporary freezing preservation of fish sperms in a field environment.

Description

technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a low-temperature freezing device suitable for fish sperm. Background technique [0002] Most of the fish sperm freezing technology in the prior art is operated in a laboratory environment. The fish sperm freezing technology uses a cooling device controlled by a computer program to realize the cooling operation of fish sperm, but it is difficult to apply this technical solution in the field Conditions of fish sperm cooling operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple fish sperm cryogenic freezing device suitable for the field. [0004] The solution that the present invention solves its technical problem is: [0005] A fish sperm cryogenic freezing device, including a foam incubator with built-in liquid nitrogen, a box cover placed on the top of the foam incubator, a storage box f...
