Description

Technical Field

[0001] This utility model belongs to the field of hydrogen energy storage technology, and in particular relates to a high-pressure hydrogen energy storage container. Background Technology

[0002] High-pressure hydrogen storage containers are containers that store hydrogen in high-pressure environments above its critical temperature, allowing for efficient storage and on-demand release. The working principle involves compressing hydrogen to the required high pressure using a compressor, then loading it into the storage container. When needed, the release of hydrogen is regulated by a pressure-reducing valve.

[0003] A search revealed that patent CN221991551U discloses a hydrogen storage tank. This device can effectively improve the situation of local high temperature or local low temperature inside through the energy conduction plate. However, the energy conduction plate is inconvenient to remove during use, and it is inconvenient to clean the inside of the container later.

[0004] Therefore, we propose a high-pressure hydrogen energy storage container. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of removing the energy transfer plate during use and the inconvenience of cleaning the inside of the container later, and to propose a high-pressure hydrogen energy storage container.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-pressure hydrogen energy storage container, comprising:

[0008] The outer shell has an inner liner fixedly installed on its inner wall, and an interface is fixedly installed between the outer shell and the inner liner. The inner wall of the interface has an internal thread, and a protective layer is provided between the outer shell and the inner liner.

[0009] It also includes multiple energy conduction plates set inside the inner liner. The cross-section of the energy conduction plates is smaller than that of the inner ring of the interface. Multiple energy conduction plates have multiple evenly distributed through holes and micro holes on their outer walls. One side of each energy conduction plate is arc-shaped and the arc-shaped side fits against the inner wall of the inner liner.

[0010] Multiple positioning mechanisms are respectively disposed on one side of multiple energy conduction plates for positioning the energy conduction plates;

[0011] A limiting mechanism is provided between multiple energy conduction plates to limit the movement of the energy conduction plates.

[0012] In one possible design, the positioning mechanism includes a positioning strip and a positioning groove. The positioning strip is fixed to the inner wall of the inner liner, and the positioning groove is opened through the outer wall of one side of the energy conduction sheet. The positioning strip and the positioning groove cooperate with each other.

[0013] In one possible design, the limiting mechanism includes multiple rectangular slots, which are respectively opened on one side of the outer wall of multiple energy conduction plates. The multiple rectangular slots have different heights, and connecting plates are rotatably connected between the inner walls on both sides of the multiple rectangular slots. The multiple connecting plates have the same length and are staggered vertically. The surfaces of the multiple connecting plates are threaded through, and the threads between the multiple threaded slots are connected by the same bolt.

[0014] In one possible design, the top and bottom ends of the positioning strip and the top and bottom inner walls of the positioning groove are both provided with bevels.

[0015] In one possible design, one edge of the positioning strip is chamfered.

[0016] In one possible design, the protective layer comprises a carbon fiber layer and a glass fiber layer, with the glass fiber layer located outside the carbon fiber layer.

[0017] In this application, during assembly, the energy conduction plate is inserted into the inner liner from the interface and aligned with the positioning strip and positioning groove to initially position the energy conduction plate. After all the energy conduction plates are installed, the connecting plate is rotated to fit against the bottom inner wall of the rectangular groove. At this time, the connecting plate is flattened so that the multiple threaded grooves are aligned. Then, the bolts are connected to the multiple threaded grooves to complete the assembly of the energy conduction plate. Then, the air inlet and outlet valves are installed on the interface. To disassemble, the above operations are repeated in reverse.

[0018] Beneficial effects: The high-pressure hydrogen energy storage container of this utility model, through the setting of multiple structures such as interface, energy conduction plate and inner liner, can facilitate the installation and disassembly of energy conduction plate, facilitate the cleaning of container, and provide convenience for later maintenance;

[0019] In this utility model, the high-pressure hydrogen energy storage container, through the setting of multiple structures such as positioning strips, positioning grooves and connecting plates, can effectively position the energy conduction sheet, prevent the energy conduction sheet from shaking randomly, and ensure the stability of the structure;

[0020] This invention allows for easy installation and disassembly of the energy conduction plate, facilitates container cleaning, and provides convenience for later maintenance. It also enables effective positioning of the energy conduction plate, preventing it from shaking and ensuring structural stability. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example 1: Refer to Figures 1-4 A storage container, comprising:

[0031] The outer shell 1 has an inner liner 2 fixedly installed on its inner wall. An interface 3 is fixedly installed between the outer shell 1 and the inner liner 2. The inner wall of the interface 3 is provided with internal threads for connecting the air inlet and outlet valves. A protective layer 4 is provided between the outer shell 1 and the inner liner 2.

[0032] It also includes multiple energy conduction plates 5 disposed inside the inner liner 2. These energy conduction plates 5 are made of materials with good thermal conductivity, such as copper or aluminum. The cross-section of the energy conduction plate 5 is smaller than that of the inner ring of the interface 3, so that the energy conduction plate 5 can pass through the interface 3. Multiple uniformly distributed through holes 6 and micro holes 7 are opened on the outer wall of the multiple energy conduction plates 5. These holes help the uniform distribution of hydrogen and heat conduction. One side of the multiple energy conduction plates 5 is set as arc and the arc side fits against the inner wall of the inner liner 2.

[0033] Multiple positioning mechanisms are respectively disposed on one side of multiple energy conduction plates 5 for positioning the energy conduction plates 5. Each positioning mechanism includes a positioning strip 12 and a positioning groove 13. The positioning strip 12 is fixed to the inner wall of the inner liner 2, and the positioning groove 13 is formed through the outer wall of one side of the energy conduction plate 5. The positioning strip 12 and the positioning groove 13 cooperate with each other. The cooperation of the positioning strip 12 and the positioning groove 13 ensures that the energy conduction plate 5 can be stably installed on the inner liner 2, preventing displacement.

[0034] A limiting mechanism is installed between multiple energy-conducting plates 5 to limit their movement. The limiting mechanism includes multiple rectangular slots 8, each formed on one outer wall of one of the energy-conducting plates 5. The rectangular slots 8 have varying heights, and connecting plates 9 are rotatably connected between the inner walls of each rectangular slot 8. The connecting plates 9 are of equal length and staggered vertically. Each connecting plate 9 has a threaded groove 10 running through its surface, and a single bolt 11 runs through each threaded groove 10. By rotating the bolt 11, the multiple energy-conducting plates 5 can be tightly connected together, achieving the limiting function and ensuring the stability of the structure.

[0035] This application can be used in the field of hydrogen energy storage, or in other fields applicable to this application.

[0038] In one aspect of this embodiment, one side edge of the positioning strip 12 is provided with a chamfer 15, which facilitates the docking of the positioning strip 12 and the positioning groove 13, making it convenient for people to assemble the energy conduction sheet 5.

[0039] In one aspect of this embodiment, the protective layer 4 includes a carbon fiber layer and a glass fiber layer, with the glass fiber layer located outside the carbon fiber layer. This combined structure can further improve the strength of the container.
