Description

Technical Field

[0001] The utility model relates to the technical field of liquid nitrogen storage tanks, in particular to a liquid nitrogen sealed storage tank with a stable structure. Background Art

[0002] Liquid nitrogen is a substance that transforms from gas to liquid at extremely low temperatures (usually -196 degrees Celsius). It has extremely low temperatures and excellent thermal stability. A liquid nitrogen storage tank is a container or device designed specifically for storing liquid nitrogen. Through its special structure and materials, the liquid nitrogen storage tank can effectively store liquid nitrogen and maintain its low temperature.

[0003] Some existing liquid nitrogen storage tanks only have a base at the bottom of the tank to enhance the stability and mobility of the tank when in use. They lack a more comprehensive protective mechanism. During transportation or movement, the tank may be impacted or collided from the side.

[0004] For example, a high-protection safety liquid nitrogen storage tank disclosed in announcement number CN217208926U can detect the liquid nitrogen concentration value at the end of the delivery pipe in real time through the liquid nitrogen concentration sensor and display meter, and display the detected liquid nitrogen concentration value to the user through the display meter, so that the user can obtain the current liquid nitrogen concentration value in a timely and convenient manner, so that the user can be informed of the leakage status in time, thereby preventing the safety hazards of liquid nitrogen leakage. The base with a shock-absorbing spring is provided to support the tank body, which not only ensures the stability of the tank body, but also effectively prevents direct impact on the tank body during transportation and movement, and avoids the problem of large vibration during the movement of the tank body, further improving the safety of liquid nitrogen use. The universal wheels also make it convenient for users to move the liquid nitrogen storage tank.

[0005] Although the design of the above-mentioned high-protection safety liquid nitrogen storage tank has enhanced the stability and mobility of the tank to a certain extent, it still has some shortcomings in fully protecting the tank. The base mainly provides bottom support, but during transportation or movement, the tank may be impacted or collided from the side. The current design does not explicitly mention protection measures for the side of the tank, such as side anti-collision pads or reinforcement structures, which may cause the tank to be damaged when subjected to lateral force.

[0006] Therefore, it is necessary to invent a liquid nitrogen sealed storage tank with a stable structure to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a liquid nitrogen sealed storage tank with a stable structure to solve the problems in the above technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid nitrogen sealed storage tank with a stable structure, comprising a storage tank body, a storage cabin and a base mechanism, the base mechanism consisting of a counterweight base plate, a positioning sleeve and a self-locking roller, the positioning sleeve is fixedly connected to the top of the counterweight base plate, the self-locking roller is installed at the bottom of the counterweight base plate, the bottom end of the storage tank body is clamped inside the positioning sleeve, the storage cabin is installed at the top of the positioning sleeve, the storage tank body is located inside the storage cabin, an opening No. 1 is provided on the surface of the storage cabin, a hatch is installed at the opening No. 1, the hatch is arranged on the front of the storage tank body, an opening No. 2 is provided on the surface of the hatch, and an operating door is installed at the opening No. 2.

[0009] The combination of the counterweight base plate, positioning sleeve and self-locking rollers provides stable support and convenient mobility for the storage tank.

[0010] Preferably, the counterweight base plate is in the shape of a quadrangular pyramid, and rubber anti-collision strips are fixedly connected to the outer sides of the counterweight base plate.

[0011] The pyramid shape increases the stability of the base, while the rubber anti-collision strips provide additional protection to prevent the tank from being damaged by collision during movement or placement.

[0012] Preferably, a rubber anti-skid pad is installed on the inner wall of the positioning sleeve, and the rubber anti-skid pad is interference-connected with the bottom end of the storage tank body.

[0013] The interference fit between the rubber anti-slip pad and the bottom of the tank body ensures the stability of the tank in the storage compartment, reduces the possibility of shaking, and thus protects the storage safety of liquid nitrogen.

[0014] Preferably, the number of the self-locking rollers is set to four, and the four self-locking rollers are respectively arranged at the four corners of the bottom of the counterweight base.

[0015] Four self-locking rollers are evenly distributed at the four corners of the bottom of the counterweight base, providing balanced support and moving force, making the tank more stable during movement, and the self-locking function ensures the stability of the device when it is stationary.

[0016] Preferably, the height of the hatch is greater than the height of the tank body, and the width of the No. 1 opening is greater than the longest diameter of the tank body.

[0017] The height of the hatch and the width of the No. 1 opening are both larger than the size of the tank body. This design facilitates the placement and removal of the tank, while also providing sufficient space for the tank and preventing operational inconveniences caused by size limitations.

[0018] Preferably, the height of the operating door is flush with the height of the valve of the storage tank body, and a transparent observation window is installed in the middle of the operating door.

[0019] The height design of the operating door allows users to operate it easily without bending over, which improves the convenience of use; and the transparent observation window allows users to observe the internal conditions of the tank without opening the operating door, further improving safety and convenience.

[0020] Preferably, a push-pull handle is hingedly provided on the back of the storage compartment, and the push-pull handle can be rotated 90 degrees to open and close.

[0021] The push-pull handle's hinged setting and 90-degree rotating opening and closing function allow users to easily grab and push the tank when they need to move it. It also makes it easy to store the handle when not in use to save space.

[0022] Preferably, the push-pull handle fits the surface of the storage compartment, and a rubber anti-slip sleeve is sleeved on the surface of the push-pull handle.

[0023] The rubber non-slip cover provides a comfortable grip and effectively prevents your hand from sliding, thereby improving safety and stability when moving the tank.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] The design of the storage cabin not only provides a closed and safe storage environment for the tank body, but also realizes fine control over the operation process of the tank body through the design of the hatch and operating door on its surface. The dual protection of the hatch and operating door not only prevents direct interference of external factors on the tank body, but also ensures convenience and safety during operation. The storage cabin combined with the base mechanism provides all-round protection for the tank body, ensuring the safety and stability of the tank body during movement, storage and operation.
