[0002] In the field of industrial gas transportation, cryogenic transport tanks are core equipment, undertaking the safe storage and transportation of cryogenic industrial gases such as liquid nitrogen, liquid oxygen, and liquid argon.

[0003] Chinese Patent Publication No. CN 221069332 U discloses a safe and efficient industrial gas transportation device, relating to the field of industrial gas transportation technology. The device includes a protective box, a base, and a gas storage tank. The base is connected to the bottom side wall of the protective box. A clamping assembly for stabilizing the position of the gas storage tank is slidably mounted on the base. A positioning assembly is detachably mounted on the top of the clamping assembly. A buffer mechanism for anti-collision is provided between the clamping assembly and the positioning assembly. This invention, by setting up the clamping assembly and the positioning assembly, uses the rotation of a screw to drive the movement of two clamping plates, thereby achieving the initial clamping of the gas storage tank by the clamping plates, achieving the purpose of fixing the position of the gas storage tank. By setting up the buffer mechanism, using horizontally and vertically filled airbags and upper and lower anti-collision pads, the vibration energy is buffered and released.

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 scope of protection of the present utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1

[0030] To address the inconvenience of fixing multiple tanks and unloading materials in existing technologies, the following solution is disclosed, specifically as follows: Figures 1-6As shown, the industrial gas cryogenic transport tank provided in this application includes a cryogenic transport outer tank 1 and partition chambers 6. The cryogenic transport outer tank 1 has three sets of partition chambers 6 inside. A movable groove 20 is provided at the top of the inner part of the cryogenic transport outer tank 1. A motor box 5 is fixed to the top of the cryogenic transport outer tank 1, and a stepper motor is fixed inside the motor box 5. The output shaft of the stepper motor extends into the movable groove 20 and is connected to a gear 22. Racks 21 are connected to both sides of the inner part of the cryogenic transport outer tank 1, and the racks 21 mesh with the gears 22. Limiting grooves 23 are evenly provided at the top of the inner part of the cryogenic transport outer tank 1. The bottom ends of the racks 21 penetrate the limiting grooves 23 and are connected to limiting plates 24. Upper positioning blocks 25 and lower positioning blocks 26 are fixed to the two ends of the inner side of the limiting plates 24, respectively. Connecting blocks 27 are fixed to the bottom of the inner side of 24, and second locking teeth 28 are evenly fixed to the inner side of the connecting blocks 27. The low-temperature transport outer tank 1 is evenly fixed to the bottom of the inner side of the low-temperature transport outer tank 1, and a movable base 9 is connected between the top ends of the slide rails 10. Side grooves 15 are fixed to both sides of the movable base 9, and first locking teeth 16 are fixed inside the side grooves 15. The first locking teeth 16 and the second locking teeth 28 are engaged. A placement seat 11 is fixed to the top of the movable base 9, and damping silicone pads 12 are provided on the top of the placement seat 11, the inner side of the upper positioning block 25 and the lower positioning block 26. The inner tank 7 is placed on the top of the placement seat 11. The low-temperature transport outer tank 1 is composed of an austenitic stainless steel inner layer 2, a high-vacuum multi-layer heat insulation intermediate layer 3 and a low-alloy high-strength steel outer layer 4.

[0031] In this embodiment, when in use, three independent partitioned cavities 6 are first set inside the cryogenic transport outer tank 1 to reduce the risk of heat conduction during multi-tank transport through physical isolation. Combined with the austenitic stainless steel inner layer 2, which has low-temperature corrosion resistance, the high-vacuum multi-layer heat insulation intermediate layer 3, which has high-efficiency heat preservation performance, and the low-alloy high-strength steel outer layer 4, which has impact resistance, a three-layer protection system is formed.

[0032] Furthermore, the design of arranging the inner tanks 7 side by side inside the cryogenic transport outer tank 1 makes reasonable use of the internal space of the cryogenic transport outer tank 1. The multiple inner tanks 7 can be flexibly configured according to different industrial gas transport needs, improving versatility and applicability. At the same time, the inner tanks 7 can be arranged and moved in an orderly manner inside the cryogenic transport outer tank 1, optimizing the internal layout.

[0033] Furthermore, by starting the stepper motor to drive the gear 22 to rotate, the gear 22 drives the two sets of racks 21 to move inward or outward simultaneously through meshing, thereby driving the limiting plate 24, the upper positioning block 25 and the lower positioning block 26 to move inward or outward simultaneously to fix or unfix the inner tank 7 at four points, ensuring that the inner tank 7 has no risk of displacement during transportation, and can fix multiple sets of inner tanks 7 at the same time. At the same time, the locking teeth on the outside of the moving base 9 and the locking teeth on the inside of the limiting plate 24 engage with each other, so that the moving base 9 can be locked simultaneously while the inner tank 7 is positioned, preventing the base from sliding during transportation and realizing a double locking safety mechanism.

[0034] Further damping silicone pads 12 cover the contact surfaces of the placement base 11, upper positioning block 25, and lower positioning block 26, which can absorb vibration energy and reduce the risk of gas leakage during use.

[0035] Example 2

[0036] This embodiment, based on Embodiment 1, effectively improves the convenience of material feeding and discharging, specifically as follows: Figure 1 , Figure 2 and Figure 4 As shown, each of the bottom ends of the movable base 9 is fixed with a slider 18, and each slider 18 is connected to the slide rail 10. Auxiliary wheels 19 are evenly fixed on both sides and the bottom end of the slider 18, and each auxiliary wheel 19 is in contact with the inner wall of the slide rail 10. Each of the outer sides of the movable base 9 is fixed with a movable door 13, and each of the two sides of the bottom end of the movable door 13 is fixed with a bottom wheel 14. Each of the sides of the movable door 13 is fixed with a handle, and each of the outer sides of the handle is provided with anti-slip texture. Each of the two sides inside the partition cavity 6 is fixed with a first baffle 8, and each of the two sides of the movable base 9 is fixed with a second baffle 17.

[0037] In this embodiment, when in use, the auxiliary wheels 19, which are evenly fixed on both sides and the bottom of the slider 18, first come into contact with the inner wall of the slide rail 10, which greatly reduces the friction when the slider 18 moves on the slide rail 10, making the process of pulling the moving base 9 to move the inner tank 7 smoother. The staff can more easily complete the movement operation of the inner tank 7, reducing labor intensity and improving work efficiency.

[0038] Furthermore, the handle on the movable door 13 is provided with anti-slip texture on the outside, which increases the friction between the worker's hand and the handle, making it more convenient and effortless to open and close the movable door 13;

[0039] After moving outward to a certain position, the first baffle 8 and the second baffle 17 fit together to limit the movement, preventing the movable base 9 from being pulled out. The limiting design of the first baffle 8 and the second baffle 17 restricts the movement range of the movable base 9, preventing the movable base 9 from coming off the slide rail 10 due to unexpected circumstances, thereby ensuring the stability of the inner tank 7 inside the cryogenic transport outer tank 1.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
