Description

Technical Field

[0001] The present invention belongs to the technical field of liquid hydrogen storage, and in particular relates to an adjustable combined storage structure of modular liquid hydrogen tanks. Background Art

[0002] As the global demand for clean energy continues to increase, liquid hydrogen, as an efficient and clean energy carrier, is becoming more and more widely used in the energy field.

[0003] However, the existing liquid hydrogen tank storage structures used for liquid hydrogen storage are mostly fixed integrated designs, which cannot be flexibly adjusted according to actual storage needs. Different application scenarios have different requirements for the storage volume and storage method of liquid hydrogen. Fixed-structure liquid hydrogen tanks are difficult to meet diverse needs, resulting in waste of resources or inadequate utilization. The existing storage structure lacks optimization in spatial layout, and the arrangement method between liquid hydrogen tanks is relatively simple, which cannot fully utilize the space. Especially in some places with limited space, such as vehicle-mounted and ship-mounted application scenarios, fixed-structure liquid hydrogen tanks will occupy a large amount of space, affecting the layout of other equipment and the compactness of the overall system.

[0004] Combining the above two points of view, it is found that it is difficult to avoid the above problems at the same time when the existing devices on the market are in use, and thus it is impossible to achieve the desired effect. Therefore, we proposed an innovative modular design and adjustable combination method to effectively solve the problems of insufficient flexibility and low space utilization of traditional liquid hydrogen tank storage structure, improve the efficiency and safety of liquid hydrogen storage, and meet the needs of different application scenarios. Summary of the invention

The advantage of the present invention is that by setting a modular hydrogen tank unit and connecting multiple auxiliary tanks through a mounting plate, the number of auxiliary tanks used can be flexibly adjusted according to actual storage needs, thereby adjusting the storage capacity of liquid hydrogen to adapt to different application scenarios. The connecting component realizes the smooth connection and on-demand flow of liquid hydrogen between the main tank and the auxiliary tank, which is convenient for the allocation and use of liquid hydrogen. By setting a mounting base with good buffering and shock absorbing performance, it can effectively absorb and disperse external vibration and impact force, protect the safety of the modular hydrogen tank unit, and improve the reliability of the entire storage structure in various environments.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A modular liquid hydrogen tank adjustable combined storage structure, comprising two support blocks, a mounting base bolted between the bottoms of the two support blocks, and a modular hydrogen tank unit arranged between the tops of the two support blocks, both sides of the mounting base surface are bolted with fixing frames, and a storage plate is bolted between the opposite sides of the two fixing frames;

[0007] The modular hydrogen tank unit includes a main tank body, which is arranged between the tops of two support blocks. A plurality of mounting plates are arranged in a ring shape on the surface of the main tank body, and adjacent mounting plates are bolted together. A sub-tank body is arranged on the side of the mounting plate close to the main tank body. Both ends of the main tank body are connected with connecting pipes, and a connecting component is sleeved on the surface of the connecting pipe, and the connecting component is connected with the side close to the sub-tank body.

[0008] By adopting the above technical solution, by setting up a modular hydrogen tank unit and connecting multiple sub-tanks through a mounting plate, the number of sub-tanks used can be flexibly adjusted according to actual storage needs, thereby adjusting the storage capacity of liquid hydrogen to adapt to different application scenarios, and the connecting component realizes the smooth connection and on-demand flow of liquid hydrogen between the main tank and the sub-tank, which is convenient for the allocation and use of liquid hydrogen. By setting up a mounting base with good buffering and shock absorbing performance, it can effectively absorb and disperse external vibration and impact force, protect the safety of the modular hydrogen tank unit, and improve the reliability of the entire storage structure in various environments.

[0010] By adopting the above technical solution, by providing a fixing clamp and a fixing ring, the auxiliary tank body can be fixed more firmly to prevent it from shaking or displacement during use, thereby improving the stability and safety of the entire storage structure.

[0011] The present invention is further configured as follows: an adjustment groove for use with a fixing clamp is opened on one side of the mounting plate close to the auxiliary tank body, and the mounting plate is slidably arranged inside the adjustment groove, a fixing bolt passes through the inside of the mounting plate, and both ends of the fixing bolt extend to the outside of the mounting plate.

[0012] By adopting the above technical solution, by setting fixing bolts and adjusting slots, the position adjustment of the fixing clamp is more flexible and convenient. The user can accurately adjust the position of the fixing clamp according to the specific size and installation quantity of the auxiliary tank body, and then tighten it with the fixing bolts to ensure the fixing effect.

[0013] The present invention is further configured as follows: the connecting component includes a ring, which is sleeved on the surface of the connecting pipe, the surface of the ring is annularly connected with a flexible tube, and the side of the flexible tube close to the auxiliary tank body is connected with it, a fixed disk is arranged inside the flexible tube close to one end of the ring, and a blockage is movably arranged inside the fixed disk, a push rod is bolted to one side of the blockage, and a pushing disk is bolted to the other end of the push rod, a return spring is sleeved on the surface of the push rod, and the return spring is connected to the pushing disk and the fixed disk on one side respectively.

[0014] By adopting the above technical solution and setting a connecting component, when liquid hydrogen is added to the main tank body through the left connecting pipe, part of the liquid hydrogen will squeeze the push plate and the push rod to move under the action of pressure, so that the reset spring will contract and the blockage will be moved out of the fixed plate, thereby releasing the blockage of the flexible tube and opening the flow channel, so that liquid hydrogen can be added to the main tank body while the liquid hydrogen in the auxiliary tank body can be replenished simultaneously. After the liquid hydrogen in the main tank body is used, the pressure in the main tank body disappears, and the liquid hydrogen pressure in the auxiliary tank body will push the push plate and the push rod in the right flexible tube to move, so that the blockage of the right flexible tube is released, and the liquid hydrogen in the auxiliary tank body can flow to the main tank body, thereby replenishing the liquid hydrogen in the main tank body.

[0015] The present invention is further configured as follows: through holes are provided inside the fixing disk, the collar and the connecting pipe, and flow channels are formed between the through holes, and two blocking and pushing disks on both sides are arranged oppositely.

[0041] The modular hydrogen tank unit 3 includes a main tank body 31, which is arranged between the tops of the two support blocks 1. A plurality of mounting plates 32 are arranged in a ring shape on the surface of the main tank body 31, and adjacent mounting plates 32 are bolted together. A sub-tank body 33 is arranged on the side of the mounting plate 32 close to the main tank body 31. Both ends of the main tank body 31 are connected with connecting pipes 34, and a connecting component 35 is sleeved on the surface of the connecting pipe 34. The connecting component 35 is connected with the side close to the sub-tank body 33. By setting the modular hydrogen tank unit 3 and connecting multiple sub-tanks 33 through the mounting plate 32, the number of sub-tanks 33 used can be flexibly adjusted according to actual storage needs, thereby adjusting the storage capacity of liquid hydrogen to adapt to different application scenarios, and the connecting component 35 realizes the smooth connection and on-demand flow of liquid hydrogen between the main tank body 31 and the sub-tank body 33, which is convenient for the allocation and use of liquid hydrogen.

[0042] like Figure 4 As shown, a fixing clamp ring 6 is slidingly provided on one side of the mounting plate 32 close to the auxiliary tank body 33, and a fixing ring 7 is bolted inside the fixing clamp ring 6. The auxiliary tank body 33 is located inside the two fixing rings 7 on both sides. By providing the fixing clamp ring 6 and the fixing ring 7, the auxiliary tank body 33 can be more firmly fixed to prevent it from shaking or displacement during use, thereby improving the stability and safety of the entire storage structure.

[0043] like Figure 4 As shown, an adjustment slot for use with a fixing clamp 6 is provided on one side of the mounting plate 32 close to the auxiliary tank body 33, and the mounting plate 32 is slidably arranged inside the adjustment slot. A fixing bolt 8 passes through the interior of the mounting plate 32, and both ends of the fixing bolt 8 extend to the outside of the mounting plate 32.

The surface of the collar 351 is annularly connected with a flexible tube 352, and the side of the flexible tube 352 close to the auxiliary tank body 33 is connected thereto. A fixed disk 353 is arranged inside the end of the flexible tube 352 close to the collar 351, and a plug 354 is movably arranged inside the fixed disk 353. A push rod 355 is bolted to one side of the plug 354, and a pushing disk 356 is bolted to the other end of the push rod 355. A return spring 357 is sleeved on the surface of the push rod 355, and the side of the return spring 357 close to the pushing disk 356 and the fixed disk 353 are respectively connected to the two. By setting the connecting component 35, when the main tank body 31 is connected to the main tank body 31 through the left connecting pipe 34, When liquid hydrogen is added, part of the liquid hydrogen will squeeze the push disk 356 and the push rod 355 under the action of pressure, so that the return spring 357 will shrink and the plug 354 will move out of the fixed disk 353, thereby releasing the blockage of the flexible tube 352 and opening the flow channel. Liquid hydrogen can be added to the main tank body 31 while the liquid hydrogen in the auxiliary tank body 33 can be replenished simultaneously. After the liquid hydrogen in the main tank body 31 is used, the pressure in the main tank body 31 disappears. The liquid hydrogen pressure in the auxiliary tank body 33 will push the push disk 356 and the push rod 355 in the right flexible tube 352 to move, so that the plug 354 releases the blockage of the right flexible tube 352, and the liquid hydrogen in the auxiliary tank body 33 can flow to the main tank body 31, thereby replenishing the liquid hydrogen in the main tank body 31.

[0045] like Figure 3 As shown, through holes are provided inside the fixed plate 353, the collar 351 and the connecting pipe 34, and flow channels are formed between the through holes. The two plugs 354 and the push plate 356 on both sides are arranged oppositely. By setting the connection of the through holes, the formation method of the flow channel is clarified, and the smoothness and stability of the flow of liquid hydrogen between the main tank body 31 and the auxiliary tank body 33 are ensured. The plugs 354 and the push plates 356 on both sides are arranged oppositely, so that the flow direction of liquid hydrogen between the main tank body 31 and the auxiliary tank body 33 can be controlled.

[0046] like Figure 5 As shown, the main tank body 31 and the auxiliary tank body 33 both include an external protective tank 12, and an inner liner 13 is arranged inside the external protective tank 12, and an insulating layer 14 is formed between the inner liner 13 and the opposite side of the external protective tank 12, and the insulating layer 14 is made of vacuum insulation material. The main tank body 31 and the auxiliary tank body 33 adopt the structural design of the external protective tank 12, the inner liner 13 and the insulating layer 14, and the external protective tank 12 provides mechanical protection to prevent the tank body from being physically damaged by the outside; the inner liner 13 is used to store liquid hydrogen; the insulating layer 14 adopts vacuum insulation material to effectively reduce heat transfer, maintain the low temperature state of liquid hydrogen, and reduce the evaporation loss of liquid hydrogen.

[0047] Brief description of the use process: install the mounting base 2 at the use position, and put a plurality of mounting plates 32 on the surface of the main tank body 31, and connect the mounting plates 32, and then adjust the number of auxiliary tank bodies 33 according to the use requirements. The mounting position of the auxiliary tank body 33 can be adjusted by sliding the fixing clamp ring 6 in the mounting plate 32, and the fixing clamp ring 6 can be fixed in the corresponding position using the fixing bolt 8 structure. When liquid hydrogen is added to the main tank body 31 through the left connecting pipe 34, part of the liquid hydrogen will squeeze the push plate 356 and the push rod 355 to move under the action of pressure, so that the return spring 357 is contracted. The plug 354 shrinks and moves out of the fixed disk 353, thereby releasing the blockage of the flexible tube 352 and opening the flow channel, so that liquid hydrogen can be added to the main tank body 31 while the liquid hydrogen in the auxiliary tank body 33 can be replenished synchronously. After the liquid hydrogen in the main tank body 31 is used, the pressure in the main tank body 31 disappears. The liquid hydrogen pressure in the auxiliary tank body 33 pushes the push disk 356 and the push rod 355 in the right flexible tube 352 to move, so that the plug 354 releases the blockage of the right flexible tube 352, and the liquid hydrogen in the auxiliary tank body 33 can flow to the main tank body 31, so as to replenish the liquid hydrogen in the main tank body 31.

The elastic deformation of the buffer spring 27 absorbs and disperses the impact force, effectively absorbing and dispersing the vibration and impact force received by the module hydrogen tank unit 3, thereby improving the stability and earthquake resistance of the structure.

[0053] like Figure 6 As shown, the bottom of the connecting plate 22 is bolted with a damping telescopic rod 15, and the bottom of the damping telescopic rod 15 is connected to the inner wall of the mounting frame 21.
