Description

Technical Field

[0001] This utility model belongs to the technical field of hydrogen storage devices, and in particular relates to a solid hydrogen storage tank assembly device. Background Technology

[0002] With the widespread application of hydrogen energy, efficient, safe and low-cost hydrogen storage technology has become crucial. Solid-state hydrogen storage has attracted increasing attention due to its advantages such as high volumetric hydrogen storage density and good safety.

[0003] Currently, to increase the total hydrogen storage capacity and enhance safety and stability, multiple hydrogen storage tanks are typically assembled together. This prevents system failure due to the limited storage capacity of a single tank or a single point of failure in a single tank. However, existing hydrogen storage tank assembly racks are either too complex, making disassembly difficult and tank replacement inconvenient, resulting in high costs; or they are too simple, offering poor stability in securing the tanks and making them prone to shaking, leading to lower safety and thus limiting the large-scale promotion and application of solid-state hydrogen storage devices. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a solid hydrogen storage tank assembly device that is easy to assemble and disassemble and has high stability, so as to solve the problems existing in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a solid hydrogen storage tank assembly device, including a fixed frame, the fixed frame including multiple support rods, a support base plate fixedly provided at the bottom of the multiple support rods, a limiting top plate detachably fixed at the top of the multiple support rods, a set interval between the support base plate and the limiting top plate, and multiple limiting holes provided on the limiting top plate; multiple hydrogen storage tanks, the bottom of the multiple hydrogen storage tanks placed on the support base plate, and the tops of the multiple hydrogen storage tanks correspondingly embedded in the multiple limiting holes on the limiting top plate; each hydrogen storage tank is filled with hydrogen storage alloy powder, each hydrogen storage tank is provided with an on / off valve, and each on / off valve on the hydrogen storage tank is connected to a gas main pipe, and a main on / off valve is provided on the gas main pipe.

[0006] Furthermore, the support base plate is provided with multiple receiving grooves, and the bottoms of the multiple hydrogen storage tanks are placed in the multiple receiving grooves one by one.

[0007] Furthermore, the diameter of the limiting hole gradually decreases from bottom to top in the vertical direction.

[0008] Furthermore, there are four support rods distributed at the four corners of the support base plate; each support rod has a threaded section at its top, and the four corners of the limiting top plate have second connecting holes. The four threaded sections are threaded through the four second connecting holes one by one. A lower fastening nut is threadedly connected to the threaded section below the limiting top plate, and an upper fastening nut is threadedly connected to the threaded section above the limiting top plate.

[0009] Furthermore, a pressure gauge and a pressure reducing valve are also installed on the main gas line.

[0010] Furthermore, the particle size range of the hydrogen storage alloy powder is 0.1 mm to 1 mm.

[0011] Furthermore, the hydrogen storage tank is also filled with thermally conductive powder.

[0012] Furthermore, the thermally conductive powder is expanded graphite powder or copper powder.

[0013] Furthermore, the hydrogen storage tank is equipped with a heating jacket on its exterior.

[0014] As described above, the solid hydrogen storage tank assembly device of this utility model has the following beneficial effects: In use, the limiting top plate is removed from the support rod, facilitating the placement of multiple hydrogen storage tanks one by one on the support base plate. Then, the limiting top plate is installed on the top of the support rod, so that the multiple limiting holes on the limiting top plate correspond one-to-one with the tops of the multiple hydrogen storage tanks. The limiting top plate is then firmly fixed relative to the support rod, thereby limiting the forward, backward, left, and right movements of each hydrogen storage tank through the limiting holes. Fixing the limiting top plate relative to the support rod prevents vertical movement of the limiting top plate, thus restricting the vertical freedom of the hydrogen storage tanks.

[0040] Please see Figures 1 to 5 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components.

[0041] This invention provides a solid-state hydrogen storage assembly device, such as... Figures 1 to 5 As shown, the solid hydrogen storage assembly device includes a fixed frame 10 and multiple hydrogen storage tanks 20. The fixed frame 10 includes multiple support rods 11, with a support base plate 12 fixedly mounted at the bottom of each support rod 11 and a limiting top plate 13 detachably fixed at the top of each support rod 11. There is a set interval between the support base plate 12 and the limiting top plate 13, and multiple limiting holes 130 are provided on the limiting top plate 13. The bottoms of the multiple hydrogen storage tanks 20 are placed on the support base plate 12, and the tops of the multiple hydrogen storage tanks 20 are correspondingly embedded in the multiple limiting holes 130 on the limiting top plate 13. Specifically, each hydrogen storage tank 20 is filled with hydrogen storage alloy powder, and each hydrogen storage tank 20 is provided with an on / off valve 201. The on / off valve 201 on each hydrogen storage tank 20 is connected to a gas main pipe 30, and a main on / off valve 301 is provided on the gas main pipe 30.

[0042] The advantages of this solid-state hydrogen storage assembly device are as follows: During use, when placing a hydrogen storage tank 20 into the fixed frame 10, the limiting top plate 13 is removed from the support rod 11, facilitating the placement of multiple hydrogen storage tanks 20 one by one onto the support base plate 12. Then, the limiting top plate 13 is installed onto the top of the support rod 11, ensuring that the multiple limiting holes 130 on the limiting top plate 13 are correspondingly fitted onto the tops of the multiple hydrogen storage tanks 20. The limiting top plate 13 is then firmly fixed relative to the support rod 11, thereby limiting the forward, backward, left, and right movements of each hydrogen storage tank 20 through the limiting holes 130. Fixing the limiting top plate 13 relative to the support rod 11 prevents vertical movement of the limiting top plate 13, thus restricting the vertical freedom of the hydrogen storage tank 20. In summary, this solid-state hydrogen storage assembly device is simple to assemble, easy to disassemble, has low manufacturing cost, and high stability.

[0043] To further improve the stability of the hydrogen storage tank 20 within the fixed frame 10, such as Figure 2 and Figure 3 As shown, in this embodiment, a plurality of receiving grooves 120 are provided on the supporting base plate 12, and the bottoms of the plurality of hydrogen storage tanks 20 are placed in the plurality of receiving grooves 120 on the supporting base plate 12 in a corresponding manner. Through this structural design, the receiving grooves 120 on the supporting base plate 12 can also limit the bottom of the hydrogen storage tanks 20 in the front-back, left-right directions, which can further improve the stability of the hydrogen storage tanks on the fixed frame 10.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the diameter of the limiting hole 130 on the limiting top plate 13 gradually decreases from bottom to top in the vertical direction, that is, the limiting hole 130 is tapered. Through this structural design, as... Figure 1 As shown, the tapered limiting hole 130 can better fit with the upper part of the hydrogen storage tank 20, increasing the contact area between the inner wall of the limiting hole 130 and the hydrogen storage tank 20, and further improving the stability of limiting the hydrogen storage tank.

[0045] Specifically, in this embodiment, four receiving grooves 120 are provided on the supporting base plate 12, and correspondingly, four limiting holes 130 are provided on the limiting top plate 13. Of course, in other optional embodiments, those skilled in the art can provide any number of receiving grooves on the supporting base plate and any number of limiting holes on the limiting top plate as needed.

[0046] Specifically, such as Figure 2 and Figure 3As shown, in this embodiment, there are four support rods 11, which are distributed at the four corners of the support base plate 12. Correspondingly, there are second connecting holes 131 at the four corners of the limiting top plate 13. Specifically, each support rod 11 has a threaded section 111 at its top. The threaded sections 111 on the four support rods 11 are distributed and correspondingly pass through the four second connecting holes 131 on the limiting top plate 13. A lower fastening nut 14 is threadedly connected to each threaded section 111 below the limiting top plate 13, and an upper fastening nut 15 is threadedly connected to each threaded section 111 above the limiting top plate 13. That is, the limiting top plate 13 is fixed to the threaded section 111 of the support column 11 by the lower fastening nut 14 and the upper fastening nut 15. In use, unscrew the upper fastening nut 15 from the threaded section 111, then remove the limiting top plate 13 from the support column 11. This allows the four hydrogen storage tanks 20 to be placed one by one into the four receiving grooves 120 on the support base plate 12. Then, insert the limiting top plate 13 from above onto the support column 11, ensuring that the four second connecting holes 131 on the limiting top plate 13 correspond to the four support columns 11. Once the limiting top plate 13 is lowered to the appropriate position, i.e., when the four limiting holes 130 on the limiting top plate 13 are tightly fitted with the upper parts of the four hydrogen storage tanks 20, tighten the lower fastening nut 14 and the upper fastening nut 15 to fix the limiting top plate 13. This achieves the fixation of the multiple storage tanks 20 placed within the fixing frame 10. The structure is simple, easy to assemble and disassemble, and low in cost.

[0047] Specifically, in order to improve the stability of the lower fastening nut 14 and the upper fastening nut 15 in fixing the limiting top plate 13, in this embodiment, gaskets are provided between the lower fastening nut 14 and the limiting top plate 13, and between the upper fastening nut 15 and the limiting top plate 13.

[0048] Specifically, such as Figure 1 As shown, in this embodiment, the support rod 11 is preferably a screw rod, with a positioning flange 110 at its bottom end. A first connecting hole 121 is provided on the support base plate 12. The diameter of the positioning flange 110 is larger than the diameter of the first connecting hole 121. The first connecting hole 121 on the support base plate 12 passes through the support rod 11, i.e., the screw rod, and the bottom wall of the support base plate 12 is in contact with the top surface of the positioning flange 110. Thus, the positioning flange 110 is used to position the support base plate 12.

[0049] Furthermore, in order to control the pressure on the gas main 30 according to the actual situation during hydrogen charging and discharging, in this embodiment, a pressure gauge and a pressure reducing valve are also provided on the gas main 30.

[0050] Specifically, in this embodiment, the hydrogen storage alloy powder includes, but is not limited to, AB5 type hydrogen storage alloy (e.g., LaNi5), AB2 type hydrogen storage alloy (e.g., TiMn2), or AB type hydrogen storage alloy (e.g., TiFe). Preferably, in order to improve the hydrogen storage performance of the hydrogen storage tank 20, in this embodiment, the particle size range of the hydrogen storage alloy powder filled in the hydrogen storage tank 20 is 0.1 mm to 1 mm.

[0051] Furthermore, to improve the heat transfer performance of the hydrogen storage tank 20, preferably, in this embodiment, the hydrogen storage tank 20 is also filled with thermally conductive powder. When the hydrogen storage alloy powder absorbs hydrogen, the heat released can be better dissipated and conducted away through the thermally conductive powder. Preferably, in this embodiment, the thermally conductive powder can be expanded graphite powder or copper powder. The expanded graphite powder or copper powder can be mixed evenly with the hydrogen storage alloy powder before being filled into the hydrogen storage tank 20, thus achieving better heat transfer effect.

[0052] Furthermore, to improve the hydrogen storage tank 20's performance during hydrogen release, preferably, in this embodiment, a heating jacket is provided outside the hydrogen storage tank. When releasing hydrogen from the hydrogen storage tank 20, the hydrogen storage alloy powder inside the tank needs to absorb heat. By providing a heating jacket outside the hydrogen storage tank 20, the tank is heated during hydrogen release, thereby significantly improving the hydrogen release performance and effectiveness of the hydrogen storage tank 20.

[0053] In summary, the solid hydrogen storage tank assembly device of this invention is simple to assemble and easy to disassemble, requiring no specialized or expensive equipment for sheet metal processing of the assembly frame, resulting in lower manufacturing costs. Furthermore, it allows for flexible adjustment of the number and performance of hydrogen storage tanks, enabling the convenient assembly of solid hydrogen storage devices with different storage capacities and output pressure requirements, demonstrating broad versatility and good expandability. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.

[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
