Among them, hydrogen energy, as a clean and efficient form of energy, has attracted much attention. However, hydrogen storage tanks are usually transported by road using trucks and trailers, and secondly, they are transported through pipelines. If hydrogen is transported by road using trucks and trailers, it needs to be bottled. However, the existing transportation equipment cannot perform anti-collision and shock absorption operations on the hydrogen storage tanks during transportation and storage. It is simply fixed with wire, which is prone to collision during transportation, causing rupture and damage of the hydrogen storage tanks, posing certain safety hazards. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Figure 1-6 As shown, the utility model provides a liquid hydrogen storage tank transport device, including a box body 1, a box cover 11 is hinged on the top of the box body 1, a placement plate 2 is fixedly installed inside the box body 1, the placement plate 2 is located at the bottom of the box body 1, a hydrogen storage tank 22 is provided on the top of the placement plate 2, and two symmetrically distributed buffer plates 23 are provided on the outside of the hydrogen storage tank 22, and a plurality of annular evenly distributed first fixing plates 24 are fixedly installed on the side of the buffer plate 23 away from the hydrogen storage tank 22, and a plurality of evenly distributed springs 25 are fixedly installed on the side of each first fixing plate 24 away from the buffer plate 23, and a second fixing plate 26 is fixedly installed on the side of the spring 25 away from the first fixing plate 24, and a connecting plate 27 is fixedly installed on the side of the second fixing plate 26 away from the spring 25, and a splint 29 is fixedly installed on both sides of the connecting plate 27.

[0019] An empty slot 3 is provided on the upper surface of the inner wall of the box body 1, and two symmetrically distributed fixed blocks 31 are fixedly installed on the upper surface of the inner wall of the empty slot 3. The top of the fixed block 31 is rotated through by a double-headed screw 32 with opposite threads on both ends. The double-headed screw 32 rotates through the box body 1, and the outer side of the double-headed screw 32 is threadedly connected to two symmetrically distributed moving blocks 33. The moving blocks 33 are slidably engaged in the empty slot 3. The moving blocks 33 are fixed on the corresponding splint 29, and the moving blocks 33 slide through the placement plate 2.

[0020] Two groups of symmetrically distributed card slots 4 are provided at the top edge of the placement plate 2. The internal sliding card of the card slot 4 is provided with a card block 41, and the card block 41 is fixed on the corresponding splint 29. By setting the card slot 4 and the card block 41, the splint 29 is more stable when moving. At the same time, when the card block 41 moves from one side of the inner wall of the card slot 4 to the other side of the inner wall, it indicates that the buffer plate 23 has been fitted with the hydrogen storage tank 22 and does not need to move forward.

[0021] A plurality of evenly distributed telescopic rods 5 are fixedly installed between each first fixing plate 24 and the second fixing plate 26 . The telescopic rods 5 are located inside the corresponding springs 25 . By providing the telescopic rods 5 , the springs 25 are more stable when being extended or retracted.

[0022] The first bevel gear 7 is fixedly installed on one side of the double-headed screw 32, and a fixing seat 71 is fixedly installed on one side of the box body 1 near the first bevel gear 7. A rotating shaft 72 is passed through one side of the fixing seat 71 for rotation, and a second bevel gear 73 is fixedly installed on the bottom end of the rotating shaft 72 for use with the first bevel gear 7. By setting the rotating shaft 72, when the rotating shaft 72 rotates through the rotating wheel, it drives the first bevel gear 7 to rotate, thereby driving the second bevel gear 73 to rotate. The cooperation between the first bevel gear 7 and the second bevel gear 73 drives the double-headed screw 32 to rotate. The threaded connection between the double-headed screw 32 and the moving block 33 drives the moving block 33 to move toward the middle or to both sides, thereby making it easier to rotate the double-headed screw 32, and the double-headed screw 32 will not be unable to rotate due to the double-headed screw 32 being too located at the bottom of the box body 1.

[0023] A protective cover 74 is fixedly installed on one side of the box body 1 close to the first bevel gear 7, and a cover 75 is hinged on the top of the protective cover 74. By setting the protective cover 74, the first bevel gear 7, the second bevel gear 73 and the rotating shaft 72 are protected to prevent them from being hit during transportation and affecting their use.

[0024] A rubber pad 8 is fixedly mounted on the lower surface of the inner wall of the box cover 11. By providing the rubber pad 8, the top of the hydrogen storage tank 22 is protected to prevent the top of the hydrogen storage tank 22 from being damaged.

[0025] Working principle: In actual use, when the hydrogen storage tank 22 is transported, the shaking generates gravity, and the shaking force directly hits the buffer plate 23. Then, after the buffer plate 23 hits the gravity, it drives the first fixed plate 24 to move in the opposite direction of the hydrogen storage tank 22, and the spring 25 contracts. Thus, the collision force is buffered by the cooperation of the buffer plate 23 and the spring 25, and then, after the gravity is buffered, the spring 25 drives the first fixed plate 24 and the buffer plate 23 to rebound, so that the buffer plate 23 fits the hydrogen storage tank 22.

[0026] After the hydrogen storage tank 22 is placed on the placement plate 2, the wheel on the rotating shaft 72 is rotated, so that the rotating shaft 72 drives the first bevel gear 7 to rotate, and then the engagement between the first bevel gear 7 and the second bevel gear 73 drives the double-headed screw 32 to rotate, thereby driving the moving block 33 and the clamping plate 29 to move toward the middle. As the clamping plate 29 moves, the connecting plate 27 and the components on the connecting plate 27 are driven to move, so that the buffer plate 23 on the connecting plate 27 fits with the hydrogen storage tank 22, thereby fixing multiple hydrogen storage tanks 22 in the box body 1.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
