Description

Technical Field

[0001] The utility model relates to a liquid nitrogen replenishment tank with a protection function, belonging to the technical field of liquid nitrogen replenishment tanks. Background Art

[0002] A liquid nitrogen replenishment tank is a portable or fixed container specifically used to replenish liquid nitrogen into a liquid nitrogen storage system or experimental equipment. It is designed with an efficient heat insulation layer and strict safety valves to ensure that an extremely low temperature can be maintained during the liquid nitrogen replenishment process and prevent accidental leakage. Such replenishment tanks are usually used in scientific research laboratories, medical institutions, frozen food processing plants and other places to quickly and safely replenish liquid nitrogen to meet the long-term and large-scale cryogenic storage or experimental needs.

[0003] In the prior art, the liquid nitrogen replenishment tank lacks a protection structure. Since liquid nitrogen will quickly evaporate and generate a large amount of nitrogen at room temperature, if the tank body accidentally topples over, it may cause the rapid outflow of liquid nitrogen, not only resulting in a waste of resources, but also possibly causing a sharp drop in the surrounding environmental temperature due to the rapid gasification of liquid nitrogen, posing a risk of frostbite to personnel. At the same time, the toppling may also cause the tank body to rupture, further exacerbating the leakage of liquid nitrogen and increasing the risk of explosion or asphyxiation accidents.

[0004] Therefore, a liquid nitrogen replenishment tank with a protection function is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a liquid nitrogen replenishment tank with a protection function to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the utility model is realized as follows: A liquid nitrogen replenishment tank with a protection function includes a liquid nitrogen tank body. A fixing plate is arranged in the middle of the surface of the liquid nitrogen tank body. Anti-toppling components are arranged on both the left and right sides of the fixing plate. The anti-toppling component includes a transmission box. The transmission box is fixedly connected to both the left and right sides of the fixing plate. Both the upper and lower sides of the inner cavity of the transmission box are movably connected with threaded rods through bearings. A threaded sleeve is threadedly connected to the surface of the threaded rod. A transmission rod is fixedly connected to the outside of the threaded sleeve. One end of the transmission rod is fixedly connected to an anti-tipping plate.

[0007] Further preferably, a limiting groove is opened on the outside of the transmission box. The outside of the transmission rod penetrates through the limiting groove and extends to the outside of the transmission box, and the outer wall of the transmission rod is in close fit with the limiting groove.

[0008] Further preferably, a sliding groove is opened on the inner wall of the transmission box. A sliding block is fixedly connected to the inside of the threaded sleeve, and the inside of the sliding block is slidably connected to the sliding groove.
