Description

Technical Field

[0001] This utility model relates to the field of cryogenic liquid storage tank technology, specifically to a cryogenic liquid storage tank. Background Technology

[0002] Cryogenic storage tanks are primarily used for the cryogenic liquid storage of gases such as liquid oxygen, liquid nitrogen, liquid argon, and carbon dioxide. One cubic meter of liquid can replace 130 gas cylinders. This eliminates the need for daily transportation of gas cylinders, saving significant human and material resources.

[0003] However, existing cryogenic liquid storage tanks are prone to leakage during transportation due to road bumps. Since drivers cannot perform timely inspections, they cannot know whether there is a leakage problem in the cryogenic liquid storage tank, resulting in significant losses.

[0004] To address these issues, we designed a cryogenic liquid storage tank. Utility Model Content

[0005] The purpose of this invention is to provide a cryogenic liquid storage tank to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cryogenic liquid storage tank, including a storage tank body. A detection frame is fixedly installed on the inner side wall of the storage tank body. A groove is opened on one side of the detection frame. A sliding plate is slidably arranged in the groove. A return spring is arranged between the sliding plate and the top wall of the groove. A rope is arranged on one side of the sliding plate. A float is arranged at the other end of the rope. A striker is arranged at the bottom of the sliding plate. An alarm triggering component is arranged in the groove. The alarm triggering component cooperates with the striker to abut.

[0007] Furthermore, the alarm triggering component includes a fixing plate, which is fixedly installed in the slide groove and located below the slide plate. An electromagnetic button is provided on the top of the fixing plate, and the striking pin cooperates with the electromagnetic button to abut against it. The alarm triggering component also includes an alarm, which is fixedly installed on the top of the storage tank and electrically connected to the electromagnetic button.

[0008] Furthermore, a telescopic rod is fixedly installed between the slide plate and the inner top wall of the slide groove, and the return spring is movably sleeved on the telescopic rod.

[0009] Furthermore, a limiting groove is formed in the slide, a gap is left between the slide plate and the slide, and a limiting component is fixedly installed on the side. A ball is rotatably provided on the other side of the limiting component, and the ball is rotatably connected in the limiting groove.

[0010] Furthermore, the limiting member has an installation cavity and a sliding opening on its interior and one side, respectively. The installation cavity is connected to the sliding opening, and the ball is rotatably disposed in the installation cavity and the sliding opening, with a portion of the ball located outside the sliding opening.

[0011] Furthermore, the number of limiting members is three, and the number of limiting grooves corresponds to the number of limiting members, and the three limiting members are respectively fixedly installed on the three side walls away from the rope body.

[0012] Furthermore, an inlet valve is provided on the top of one side of the storage tank, and a faucet is provided on the bottom of the other side of the storage tank. The storage tank, the inlet valve, and the faucet are connected in coordination.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: if the storage tank leaks, the liquid will seep out of the storage tank, causing the liquid level inside the storage tank to drop. At this time, the float will pull the rope downward due to its own weight, causing the rope to drive the slide plate to stretch the return spring and move downward. At the same time, the striker will hit the electromagnetic button, which can then send an electrical signal to the alarm and sound an alarm. Personnel can deal with the leaking storage tank in time according to the alarm sound, which helps to reduce losses.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the sliding of the skateboard will drive the ball to roll in the limiting groove, which can not only limit the skateboard and guide its movement direction, but also change the sliding friction of the skateboard in the groove to rolling friction, reducing the friction force, thereby avoiding the problem of jamming due to excessive friction of the skateboard in the groove, and ensuring the stability of the detection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a cryogenic liquid storage tank, including a storage tank body 1, a detection frame 2 fixedly installed on the inner side wall of the storage tank body 1, a slide groove 3 opened on one side of the detection frame 2, a slide plate 4 slidably arranged in the slide groove 3, a return spring 5 arranged between the slide plate 4 and the inner top wall of the slide groove 3, a rope 6 arranged on one side of the slide plate 4, a float ball 7 arranged at the other end of the rope 6, a striker 8 arranged at the bottom of the slide plate 4, and an alarm triggering component arranged in the slide groove 3, the alarm triggering component and the striker 8 cooperating to resist each other;

[0022] The alarm triggering component includes a fixing plate 9, which is fixedly installed in the slide 3 and located below the slide plate 4. An electromagnetic button 10 is provided on the top of the fixing plate 9, and the striking pin 8 cooperates with the electromagnetic button 10 to abut against it. The alarm triggering component also includes an alarm 17, which is fixedly installed on the top of the storage tank 1 and is electrically connected to the electromagnetic button 10. An inlet valve 18 is provided on the top of one side of the storage tank 1, and a faucet 19 is provided on the bottom of the other side of the storage tank 1. The storage tank 1, the inlet valve 18, and the faucet 19 are connected in cooperation.

[0023] In practice, the liquid that needs to be stored cold is injected into the storage tank 1 through the liquid inlet valve 18 until the float 7 floats on the surface of the liquid, so that the storage tank 1 can be transported conveniently.

[0024] If a leak occurs in storage tank 1 during transportation, liquid will seep out of the tank, causing the liquid level inside the tank to drop. At this time, the float 7 will pull the rope 6 downward due to its own weight, causing the rope 6 to drive the slide plate 4 to stretch the return spring 5 and move downward. Simultaneously, the striker 8 will strike the electromagnetic button 10, which will then send an electrical signal to the alarm 17 and sound an alarm. Personnel can then promptly handle the leaking storage tank 1 based on the alarm sound, which helps to reduce losses.

[0025] See Figure 1-4 A telescopic rod 11 is fixedly installed between the slide plate 4 and the inner top wall of the slide groove 3, and a return spring 5 is movably sleeved on the telescopic rod 11. This can limit the sliding direction of the slide plate 4 and prevent the slide plate 4 from deviating from its intended direction.

[0026] See Figure 1-4 A limiting groove 12 is provided in the sliding groove 3. A gap is left between the sliding plate 4 and the sliding groove 3, and a limiting component 13 is fixedly installed on the side. A ball bearing 14 is rotatably provided on the other side of the limiting component 13. The ball bearing 14 is rotatably connected in the limiting groove 12. An installation cavity 15 and a sliding opening 16 are respectively provided inside the limiting component 13 and on one side. The installation cavity 15 and the sliding opening 16 are connected. The ball bearing 14 is rotatably provided in the installation cavity 15 and the sliding opening 16, and part of the ball bearing 14 is located outside the sliding opening 16.

[0027] In specific implementation, based on the above implementation, the movement of the slide plate 4 will drive the ball bearing 14 to roll in the limiting groove 12. This not only limits the slide plate 4 and guides its movement direction, but also changes the sliding friction of the slide plate 4 in the groove 3 to rolling friction, reducing the friction force. This avoids the problem of jamming caused by excessive friction of the slide plate 4 in the groove 3, and ensures the stability of the detection.

[0028] See Figure 1-4 There are three limiting members 13, and the number of limiting grooves 12 corresponds to the number of limiting members 13. The three limiting members 13 are respectively fixedly installed on the three side walls away from the rope body 6. This can further reduce the friction of the slide plate 4 inside the slide groove 3.

[0029] Working principle: Before use, all electrical appliances inside and outside the storage tank 1 need to be connected to an external power source, or a battery pack needs to be installed on the storage tank 1 in an area that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring the normal operation and switching of the electrical appliances. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0030] When in use, the liquid that needs to be stored cold needs to be injected into the storage tank 1 through the liquid inlet valve 18 until the float 7 floats on the surface of the liquid, so that the storage tank 1 can be transported conveniently.

[0031] If a leak occurs in storage tank 1 during transportation, liquid will seep out of the tank, causing the liquid level inside the tank to drop. At this time, the float 7 will pull the rope 6 downward due to its own weight, causing the rope 6 to drive the slide plate 4 to stretch the return spring 5 and move downward. Simultaneously, the striker 8 will strike the electromagnetic button 10, which will then send an electrical signal to the alarm 17 and sound an alarm. Personnel can then promptly handle the leaking storage tank 1 based on the alarm sound, which helps to reduce losses.

[0032] During the above operation, the slide plate 4 will drive the ball bearing 14 to roll in the limiting groove 12. This not only limits the slide plate 4 and guides its movement, but also changes the sliding friction of the slide plate 4 in the groove 3 to rolling friction, reducing the friction force. This avoids the problem of jamming caused by excessive friction of the slide plate 4 in the groove 3, thus ensuring the stability of the detection.
