A stabilization device for LNG transportation is a specialized equipment or system used to fix LNG tanks during LNG transportation and ensure structural safety, thereby guaranteeing transportation safety and economy.
[0003] To this end, patent CN213355313U discloses a stabilizing device for liquefied natural gas (LNG) transportation, including a support frame with a fixing structure installed on it. The fixing structure includes several guide columns, several tension springs, several fixing plates, and a tension adjustment part. The two ends of the guide columns are respectively fixed to the support frame, the upper ends of the tension springs are respectively embedded in the upper end of the support frame, and the two ends of the fixing plates pass through the guide columns and the upper end faces are fixed to the lower ends of the tension springs. This utility model relates to the field of LNG transportation equipment technology, effectively avoiding friction and collision between adjacent LNG storage tanks, making the transportation of LNG storage tanks safer.

[0031] Please see Figure 1-5 The present invention provides a stabilizing device for liquefied natural gas transportation, including a base 1.
[0032] Reference Figure 1 , Figure 2 and Figure 4As shown, a housing 2 is fixed to the top of the base 1. A placement groove 3 is provided inside the housing 2. A fixing structure 4 is installed inside the placement groove 3. The fixing structure 4 includes a motor 401 fixed to the top of the housing 2. A threaded rod 402 is fixed to the output end of the motor 401. A movable plate 403 is installed on the outside of the threaded rod 402 inside the placement groove 3.

Guide rods 406 are fixed to both sides inside the placement groove 3. Sliding holes 407 are provided on the outside of the guide rods 406 inside the connecting plate 405. A spring 408 is installed on the outside of the guide rods 406 at the bottom end of the connecting plate 405. Placement grooves 408 are fixed to both sides at the bottom end of the placement groove 3. The bottom of the seat 409 and the top of the movable plate 403 are both provided with fixing grooves 410. The movable plate 403 and the threaded rod 402 are connected by a threaded groove 404. The connecting plates 405 are symmetrically distributed on both sides of the movable plate 403. The two ends of the guide rod 406 are fixedly connected to the two ends inside the box 2. The connecting plates 405 and the guide rod 406 correspond one-to-one. The connecting plates 405 and the guide rod 406 are slidably connected by sliding holes 407. The connecting plates 405 and the guide rod 406 are telescopically connected by springs 408. The placement seat 409 is symmetrically distributed at the bottom of the placement groove 3. The fixing groove 410 is arc-shaped. A rubber pad is fixed on the inner side of the fixing groove 410. The tank 5 is placed inside the placement groove 3.
[0033] The can 5 is placed inside the fixing groove 410 on the placement seat 409. Then, by starting the motor 401, the threaded rod 402 is driven to rotate, causing the moving plate 403 to move downward along the threaded groove 404. The moving plate 403 drives the connecting plate 405 to slide along the guide rod 406. At the same time, the spring 408 is compressed, causing the moving plate 403 to drive the fixing groove 410 to move downward, thereby clamping the can 5. After the can 5 is stably fixed, the motor 401 stops running. Anti-slip rubber pads are attached to the inside of the fixing groove 410 to improve the anti-slip and cushioning effect of the can 5.
[0034] Reference Figure 2 , Figure 3 and Figure 5As shown, a reinforcing structure 6 is provided inside the base 1. The reinforcing structure 6 includes a central cavity 601 inside the base 1, and movable cavities 602 are provided inside the base 1 on both sides of the central cavity 601. A first bidirectional lead screw 603 is installed inside the central cavity 601 and the movable cavities 602. A second bidirectional lead screw 604 is installed inside the central cavity 601 on one side of the first bidirectional lead screw 603. A drive gear 605 is fixed to the outside of the first bidirectional lead screw 603 inside the central cavity 601, and a driven gear 606 is fixed to the outside of the second bidirectional lead screw 604. A first moving block 607 is installed to the outside of the first bidirectional lead screw 603 inside the movable cavity 602. A first slider 608 is fixed to the top of the first moving block 607. A first groove 609 is provided at the bottom of the outer housing 2 of the first slider 608. A second moving block 610 is installed to the outside of the second bidirectional lead screw 604 inside the central cavity 601. The top of the second movable block 610 is fixed with a second slider 611. The bottom of the outer box 2 of the second slider 611 is provided with a second sliding groove 612. The top of the first slider 608 and the second slider 611 inside the placement groove 3 are both fixed with connecting rods 613. The top of the connecting rods 613 is fixed with a fixing plate 614. One side of the fixing plate 614 is fixed with an elastic column 615. One end of the first bidirectional lead screw 603 on the outer side of the base 1 is fixed with a rotating block 616. The movable cavity 602 is symmetrically distributed inside the base 1 on both sides of the central cavity 601. The driving gear 605 and the driven gear 606 are meshed. The first movable block 607 is threadedly connected to the first bidirectional lead screw 603. The second movable block 610 is threadedly connected to the second bidirectional lead screw 604. The fixing plates 614 are symmetrically distributed on both sides of the tank 5. The elastic columns 615 are evenly distributed on one side of the fixing plate 614.
[0035] By rotating the rotating block 616, the first bidirectional lead screw 603 is driven to rotate, which in turn drives the meshing rotation of the driving gear 605 and the driven gear 606, causing the second bidirectional lead screw 604 to rotate synchronously. This causes the first bidirectional lead screw 603 to drive the two sets of first moving blocks 607 to move closer together, while the second bidirectional lead screw 604 drives the two sets of second moving blocks 610 to move further apart. As a result, the first moving blocks 607 and the second moving blocks 610 respectively push the connecting rod 613 and the fixing plate 614 closer together to the tank body 5. The elastic column 615 on the fixing plate 614 fits against the surface of the tank body 5, providing flexible clamping and avoiding damage caused by rigid contact. This achieves all-round stability of the tank body during transportation, effectively reducing vibration and impact, and improving transportation safety and reliability.
