Description

Technical Field

[0001] This utility model belongs to the field of liquid hydrogen container technology, and in particular relates to a novel container for transporting liquid hydrogen. Background Technology

[0002] A liquid hydrogen transport container is a container specifically designed for storing and transporting liquid hydrogen. Liquid hydrogen is a cryogenic liquid that typically needs to be stored at very low temperatures (approximately -253°C) to maintain its liquid state. Therefore, the design of such a container must be effectively insulated to prevent the hydrogen from evaporating due to external temperature variations during transport.

[0003] Currently, containers filled with liquid hydrogen are quite heavy during transportation. If these containers shake and collide with other objects during transport, the heavy liquid hydrogen containers have significant inertia, which can cause them to deform or even leak.

[0004] Therefore, we propose a novel container for transporting liquid hydrogen. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a new type of container for transporting liquid hydrogen.

[0006] To achieve the above objectives, this utility model proposes a novel container for transporting liquid hydrogen, including a liquid hydrogen transport tank. The liquid hydrogen transport tank is provided with a tank protection assembly, which includes a protective component and an auxiliary positioning component. The protective component is sleeved on the liquid hydrogen transport tank, and the auxiliary positioning component is disposed on the liquid hydrogen transport tank and connected to the protective component.

[0007] Preferably, the protective component includes a first protective frame and a second protective frame. The cross-sections of the first protective frame and the second protective frame are U-shaped. An insert plate is provided on the side wall opposite to the first protective frame and the side wall opposite to the first protective frame is provided with an insertion port. The insert plate on the first protective frame is inserted into the insertion port on the second protective frame, and a fixing rod is provided on the second protective frame.

[0008] Preferably, one end of the fixing rod is provided with a plurality of elastic plates, the elastic plates are inclined plates and inclined outward of the fixing rod, one end of the elastic plate is provided with a positioning block, the cross-section of the positioning block is a right triangle, the tip of the positioning block faces the liquid hydrogen transport tank, one end of each elastic plate passes through the second protective frame and the insert plate inserted in the second protective frame, and one end of the positioning block on the insert plate passing through the second protective frame is abutted on the second protective frame.

[0009] Preferably, a positioning ring is fitted on the fixing rod, and the outer wall surface of the fixing rod and the inner wall surface of the positioning ring are threaded together. The fixing rod and the positioning ring are connected by the thread. A limiting groove is formed on the outer wall surface of the elastic plate. The limiting groove is located on one side of the positioning block. The limiting grooves on the multiple elastic plates are positioned in correspondence with each other. A constraint ring is fitted on the multiple elastic plates and is fitted on the limiting grooves on the multiple elastic plates.

[0010] Preferably, the auxiliary positioning component includes a fixing ring sleeved on the liquid hydrogen transport tank and a first connecting seat disposed on the second protective frame. The fixing ring is provided with a second connecting seat, and the first connecting seat is inserted into the second connecting seat on the fixing ring. The second connecting seat is provided with a positioning rod, and a positioning pin is inserted into the positioning rod. A positioning ring is rotatably disposed on the positioning pin.

[0011] Preferably, one end of the fixing rod is provided with a cross-shaped groove, a support base is provided on the inner side of the first protective frame, an arc-shaped groove is provided on the support base, and the liquid hydrogen transport tank is placed inside the arc-shaped groove on the support base.

[0012] Preferably, the liquid hydrogen transport tank includes a protective outer shell and a high-pressure tank body. The high-pressure tank body is located inside the protective outer shell, and a support ring is fitted on the high-pressure tank body. The end of the support ring away from the high-pressure tank body is abutted against the inner wall of the protective outer shell.

[0013] The novel liquid hydrogen transport container proposed in this utility model can bring the following beneficial effects:

[0014] The tank protection components not only protect the liquid hydrogen transport tank, preventing it from deforming due to shaking or direct collisions with other objects during transport, which could lead to leakage in severe cases, but also ensure the second protective frame is securely attached to the first. This is achieved by pressing a fixing rod to lock a positioning block on the elastic plate of the fixing rod into the second protective frame. This method simplifies the installation process and increases efficiency. Furthermore, auxiliary positioning components can fix the liquid hydrogen transport tank in place, preventing it from separating from the tank protection components during transport.

[0031] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention proposes a novel container for transporting liquid hydrogen, including a liquid hydrogen transport tank 1. The liquid hydrogen transport tank 1 is provided with a tank body protection component 2. The tank body protection component 2 includes a protective component 21 and an auxiliary positioning component 22. The protective component 21 is sleeved on the liquid hydrogen transport tank 1, and the auxiliary positioning component 22 is disposed on the liquid hydrogen transport tank 1 and connected to the protective component 21.

[0032] The protective component 21 includes a first protective frame 211 and a second protective frame 212. The cross-sections of the first protective frame 211 and the second protective frame 212 are U-shaped. An insert plate 213 is provided on the side wall of the first protective frame 211 and the second protective frame 212 opposite to the first protective frame 211. An insertion port is provided on the side wall of the second protective frame 212 opposite to the first protective frame 211. The insert plate 213 on the first protective frame 211 is inserted into the insertion port on the second protective frame 212. A fixing rod 214 is provided on the second protective frame 212. One end of the fixing rod 214 is provided with a plurality of elastic plates 216. The elastic plates 216 are inclined plates and are inclined outward of the fixing rod 214. One end of the elastic plate 216 is provided with a positioning block 217. The cross-section of the positioning block 217 is a right triangle. The tip of the positioning block 217 faces the liquid hydrogen transport tank 1. One end of each elastic plate 216 passes through the second protective frame 212 and the insert plate 213 inserted in the second protective frame 212. One end of the positioning block 217 on the insert plate 213 passing through the second protective frame 212 is abutted against the second protective frame 212. A positioning ring 215 is fitted onto the fixing rod 214. The outer wall surface of the fixing rod 214 and the inner wall surface of the positioning ring 215 are threaded together with a thread 2110. The fixing rod 214 and the positioning ring 215 are connected by the thread 2110. A limiting groove 218 is formed on the outer wall surface of the elastic plate 216. The limiting groove 218 is located on one side of the positioning block 217. The limiting grooves 218 on the multiple elastic plates 216 are positioned in correspondence with each other. A constraint ring 219 is fitted onto the multiple elastic plates 216. The constraint ring 219 is fitted onto the limiting grooves 218 on the multiple elastic plates 216. The auxiliary positioning component 22 includes a fixing ring 221 sleeved on the liquid hydrogen transport tank 1 and a first connecting seat 223 set on the second protective frame 212. The fixing ring 221 is provided with a second connecting seat 222, and the first connecting seat 223 is inserted into the second connecting seat 222 on the fixing ring 221. The second connecting seat 222 is provided with a positioning rod 224, and a positioning pin 225 is inserted into the positioning rod 224. A positioning ring 2250 is rotatably set on the positioning pin 225.

[0033] In this embodiment, when the liquid hydrogen transport tank 1 needs to be transported, the liquid hydrogen transport tank 1 is placed inside the first protective frame 211, and then the second protective frame 212 is placed on the upper end face of the first protective frame 211, with the insert plate 213 on the first protective frame 211 inserted into the socket on the second protective frame 212. Then, the positioning block 217 on the elastic plate 216 on the fixing rod 214 passes through the second protective frame 212 and the insert plate 213 inserted into the second protective frame 212. During the process of the positioning block 217 passing through the second protective frame 212... The constraint ring 219 will abut against the second protective frame 212. As the positioning block 217 continues to move, the constraint ring 219 will slide out from the inside of the limiting groove 218 and slide along the outer wall of the elastic plate 216 towards the fixing rod 214. When the positioning block 217 moves to the bottom of its stroke, the positioning block 217 on the positioning block 217 passes through the second protective frame 212 and one end of the positioning block 217 passing through the second protective frame 212 abuts against the second protective frame 212, and the constraint ring 219 abuts against the positioning ring 215. Then, the first on the second protective frame 212... The connecting seat 223 is inserted into the second connecting seat 222 on the fixing ring 221. Then, one end of the positioning rod 224 is passed through the second connecting seat 222 where the first connecting seat 223 is inserted. Next, the positioning pin 225 is inserted into the positioning rod 224, and the positioning ring 2250 is rotated until it is fitted onto one end of the positioning rod 224. At this point, when the liquid hydrogen transport tank 1 collides with an object during transport, the object will directly collide with the protective component 21 fitted onto the liquid hydrogen transport tank 1. If it is necessary to connect the second protective frame 212 with... When disassembling the first protective frame 211, the positioning ring 215 can be rotated to separate it from the fixing rod 214. Then, push one end of the fixing rod 214 to pass through the second protective frame 212 and remove the fixing rod 214 from the second protective frame 212. This will separate the second protective frame 212 from the first protective frame 211. If it is necessary to disassemble the second protective frame 212 from the liquid hydrogen transport tank 1, the steps described above for the installation of the second protective frame 212 and the liquid hydrogen transport tank 1 can be reversed.

[0034] It should be noted that the inner height of the second protective frame 212 and the first protective frame 211 connected together is adapted to the diameter of the liquid hydrogen transport tank 1.

[0035] The tank protection component 2 not only protects the liquid hydrogen transport tank 1, preventing it from deforming due to shaking or direct collision with other objects during transport, but also avoids leakage caused by severe collisions. Furthermore, the installation between the second protective frame 212 and the first protective frame 211 is achieved by pressing the fixing rod 214 to lock the positioning block 217 on the elastic plate 216 of the fixing rod 214 into the second protective frame 212. This method simplifies the installation process and increases efficiency. Additionally, the auxiliary positioning component 22 can fix the position of the protected liquid hydrogen transport tank 1, preventing it from separating from the tank protection component 2 during transport.

[0036] One end of the fixing rod 214 has a cross-shaped groove 3, and a support base 4 is provided inside the first protective frame 211. The support base 4 has an arc-shaped groove 5, and the liquid hydrogen transport tank 1 is placed inside the arc-shaped groove 5 on the support base 4. The support base 4 and the arc-shaped groove 5 provide support for the liquid hydrogen transport tank 1 placed inside the first protective frame 211.

[0037] The liquid hydrogen transport tank 1 includes a protective outer shell 11 and a high-pressure tank 12. The high-pressure tank 12 is located inside the protective outer shell 11, and a support ring 13 is fitted onto the high-pressure tank 12. The end of the support ring 13 away from the high-pressure tank 12 rests against the inner wall of the protective outer shell 11. The high-pressure tank 12 is used to store liquid hydrogen. The protective outer shell 11 protects the high-pressure tank 12 from direct puncture by sharp objects, preventing leakage of liquid hydrogen inside the high-pressure tank 12. The support ring 13 supports the protective outer shell 11 located outside the high-pressure tank 12.

[0038] Working principle:

[0039] When liquid hydrogen transport tank 1 needs to be transported, it is placed in the arc-shaped groove 5 on the upper end face of the support base 4 inside the first protective frame 211. Then, the second protective frame 212 is placed on the upper end face of the first protective frame 211, and the insert plate 213 on the first protective frame 211 is inserted into the socket on the second protective frame 212. Then, the positioning block 217 on the elastic plate 216 on the fixing rod 214 passes through the second protective frame 212 and the insert plate 213 inserted into the second protective frame 212. During process 2, the constraint ring 219 will abut against the second protective frame 212. As the positioning block 217 continues to move, the constraint ring 219 will slide out from the inside of the limiting groove 218 and slide along the outer wall of the elastic plate 216 towards the fixing rod 214. When the positioning block 217 moves to the bottom of its stroke, the positioning block 217 on the positioning block 217 passes through the second protective frame 212, and one end of the positioning block 217 passing through the second protective frame 212 abuts against the second protective frame 212. The constraint ring 219 abuts against the positioning ring 215. Then the second protective frame 212... The first connecting seat 223 is inserted into the second connecting seat 222 on the fixing ring 221. Then, one end of the positioning rod 224 is passed through the second connecting seat 222 where the first connecting seat 223 is inserted. Next, the positioning pin 225 is inserted into the positioning rod 224, and the positioning ring 2250 is rotated so that the positioning ring 2250 is fitted onto one end of the positioning rod 224. At this time, when the liquid hydrogen transport tank 1 collides with an object during transportation, the object will directly collide with the protective piece 21 fitted on the liquid hydrogen transport tank 1. If it is necessary to remove the second protective frame 21, the object will directly collide with the object. When disassembling the first protective frame 211, the positioning ring 215 can be rotated to separate it from the fixing rod 214. Then, push one end of the fixing rod 214 to pass through the second protective frame 212 and remove the fixing rod 214 from the second protective frame 212. This will separate the second protective frame 212 from the first protective frame 211. If it is necessary to disassemble the second protective frame 212 from the liquid hydrogen transport tank 1, the steps described above for the installation of the second protective frame 212 and the liquid hydrogen transport tank 1 can be reversed.
