Description
Technical Field
[0001] The utility model relates to the technical field of liquefied natural gas transportation, in particular to a large-capacity LNG gas storage cylinder for long-distance transport vehicles. Background Art
[0002] LNG refers to "liquefied natural gas". It is obtained by purifying natural gas and cooling it deeply to about -162°C, causing it to change from a gaseous state to a liquid state. LNG has the advantages of high energy density and relatively high safety.
[0003] The transportation of liquefied natural gas (LNG) is a relatively complex and crucial process. Among them, tanker transportation is mainly used for short-distance or medium-distance land transportation and is relatively flexible.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Refer to Figures 1 - 3, An embodiment provided by the present utility model: A large-capacity LNG storage cylinder for a long-distance transport vehicle, including a cylinder body 1 and a bottom plate 2. A fixing frame 3 is fixedly connected to the outer wall of the cylinder body 1. A motor 4 is fixedly connected to the outer wall of the fixing frame 3. A first sprocket 5 is fixedly connected to the output end of the motor 4. A chain 6 is meshed with the outer wall of the first sprocket 5. A second sprocket 7 is meshed with the inner wall of the chain 6. A rotating shaft 8 is rotatably connected to the inside of the second sprocket 7. The outer wall of the rotating shaft 8 is fixedly connected to the outer wall of the fixing frame 3. A rotating block 9 is fixedly connected to the outer wall of the chain 6. A slider 10 is rotatably connected to the outer wall of the rotating block 9. A slide rail 11 is fixedly connected to the outer wall of the fixing frame 3. The lower outer wall of the rotating block 9 is slidably connected to the inside of the slide rail 11. A water pipe 12 is fixedly connected to the upper outer wall of the slider 10. A nozzle 13 is arranged on the outer wall of the water pipe 12. A support frame 14 is slidably connected to the outer wall of the water pipe 12. The outer wall of the support frame 14 is fixedly connected to the outer wall of the cylinder body 1. A conveying assembly is arranged on the outer wall of the cylinder body 1, and the conveying assembly is used for conveying a cooling liquid.
[0027] Specifically, by starting the motor 4 to drive the first sprocket 5 at the output end to rotate, the first sprocket 5 drives the chain 6 to move. At the same time, the chain 6 drives the second sprocket 7 to rotate. The rotating shaft 8 supports the rotation of the second sprocket 7. The chain 6 drives the rotating block 9 to slide horizontally. When the rotating block 9 slides close to the second sprocket 7 or the first sprocket 5, the rotating block 9 starts to rotate. A limiting groove is provided inside the slider 10. When the rotating block 9 rotates, it slides in the limiting groove of the slider 10 at the same time. When the rotating block 9 rotates 180 degrees, the rotating block 9 starts to slide in the reverse direction. The rotating block 9 drives the water pipe 12 to slide through the slider 10, which can cover the entire upper outer wall of the cylinder body 1 and save the coolant as much as possible.
[0028] Referring to Figure 2 and Figure 3 , the conveying assembly includes a water tank 15. The outer wall of the water tank 15 is fixedly connected to the outer wall of the cylinder body 1. A water pump 16 is fixedly connected to the inside of the water tank 15. A hose 17 is fixedly connected to the output end of the water pump 16. The outer wall of the hose 17 is fixedly connected to the lower surface of the slider 10.
[0029] Specifically, the inside of the water tank 15 is filled with a coolant. The coolant can be pumped out through the water pump 16 and conveyed to the inside of the slider 10 through the hose 17. The inside of the slider 10 is hollow and is connected to the hose 17 and the water pipe 12 at the same time. The coolant is conveyed to the water pipe 12 through the slider 10, and the water pipe 12 sprays the coolant onto the cylinder body 1 through the nozzle 13.
[0030] Referring to Figure 1 , Figure 4 and Figure 5, a fixing cylinder 18 is fixedly connected to the upper surface of the bottle body 1, and a sleeve 19 is slidably connected to the outer wall of the fixing cylinder 18; a connecting rod 20 is rotatably connected to the outer wall of the sleeve 19, and a sliding rod 21 is rotatably connected to the outer wall of the connecting rod 20; a tension spring 22 is fixedly connected to the outer wall of the sliding rod 21, and the outer wall of the tension spring 22 is fixedly connected to the upper outer wall of the fixing cylinder 18; a limiting block 23 is fixedly connected to the outer wall of the sliding rod 21, and the outer walls of the limiting block 23 and the sliding rod 21 are both slidably connected inside the fixing cylinder 18; a fixing column 24 is fixedly connected to the outer wall of the bottle body 1, a clamping block 25 is fixedly connected to the lower surface of the fixing column 24, and the outer wall of the clamping block 25 is slidably connected inside the fixing cylinder 18, and the outer wall of the clamping block 25 is arranged on the outer wall of the limiting block 23; an opening plate 26 is fixedly connected to the outer wall of the sleeve 19, a hook 27 is rotatably connected to the upper outer wall of the sleeve 19, and the lower outer wall of the hook 27 is arranged inside the upper side of the opening plate 26.
[0031] Specifically, a clamping block 25 is fixedly connected to the lower surface of the fixing column 24. The clamping block 25 can squeeze the limiting block 23 to slide, and the resilience of the tension spring 22 can drive the limiting block 23 to slide back to the starting position to block the clamping block 25, thereby fixing the bottle body 1. A chute is opened on the outer wall of the fixing cylinder 18, and the sleeve 19 slides in the chute of the fixing cylinder 18. By pushing the sleeve 19 upward, the sleeve 19 can drive the connecting rods 20 on both sides to rotate, the connecting rods 20 drive the sliding rod 21 to slide outward, and the sliding rod 21 drives the limiting block 23 to slide outward. At this time, the fixing column 24 and the clamping block 25 can be pulled out of the fixing cylinder 18. Limit holes are opened inside the opening plate 26. When there are fewer people, by rotating the hook 27, it can be inserted into the limit holes of the opening plate 26, thereby fixing the sleeve 19 and keeping the limiting block 23 in an open state all the time.
[0032] Working principle: When using this large-capacity LNG gas storage cylinder, the cylinder body 1 is hoisted by a crane, so that the fixed column 24 drives the clamping block 25 to insert into the inside of the fixed cylinder 18. The clamping block 25 will first squeeze the limit block 23 to slide outwards. The clamping block 25 slides across the limit block 23, and the tension spring 22 rebounds to drive the limit block 23 to slide towards the middle. The limit block 23 fixes the clamping block 25 to complete the hoisting. When the outer wall temperature of the cylinder body 1 rises, start the water pump 16 to pump the coolant from the inside of the water storage tank 15. The inside of the slider 10 is hollow, and then it is conveyed to the water pipe 12 through the hose 17 via the slider 10, and finally sprayed by the nozzle 13. By starting the motor 4 to drive the sprocket one 5 at the output end to rotate, the sprocket one 5 drives the sprocket two 7 to rotate through the chain 6, and the chain 6 drives the rotating block 9 to slide. When the rotating block 9 slides close to the sprocket one 5 or the sprocket two 7, the rotating block 9 will rotate and slide in the chute of the slider 10, achieving the effect of reciprocally spraying the outer wall of the cylinder body 1, thereby reducing the outer wall temperature of the cylinder body 1. When it is necessary to disassemble the cylinder body 1, push up the sleeve 19 to drive the connecting rod 20 to rotate, the connecting rod 20 drives the sliding rod 21 to slide, and the sliding rod 21 drives the limit block 23 to slide. At this time, the fixed column 24 can be pulled out. When there are not enough personnel, the opening plate 26 can be hooked by the hook 27 to prevent the opening plate 26 and the sleeve 19 from falling, so that the limit block 23 is always in the open state. This large-capacity LNG gas storage cylinder can reduce the outer wall temperature of the cylinder body 1, improve safety, and is also convenient for loading and unloading operations, improving the work efficiency of loading and unloading, and using less human resources.
