Description

Technical Field

[0001] The utility model relates to the field of hydrogen storage, specifically a high-pressure hydrogen storage tank. Background Technique

[0002] Hydrogen production by electrolyzing water is a technology that decomposes water into hydrogen and oxygen through an electrolysis process. This technology can be achieved using different electrolytic cells and electrolytes, including alkaline water electrolysis, proton exchange membrane water electrolysis, high-temperature solid oxide water electrolysis, and solid polymer anion exchange membrane water electrolysis, etc.; Hydrogen is a clean and renewable energy source with a very high energy density. A hydrogen storage tank is a tank used to store hydrogen. Compressing hydrogen into a liquid state and storing it in a hydrogen storage tank is convenient for transportation and use.

[0003] For example, the patent with the authorization announcement number CN221069073U discloses a fixing device for a hydrogen storage tank, which relates to the technical field of hydrogen storage tank transportation. It includes a bottom plate. On both sides of the top of the bottom plate, there are respectively a left frame and a right frame. A hydrogen storage tank is arranged between the left frame and the right frame. A groove is opened at the center of the top of the bottom plate. A number of first springs are arranged equidistantly in the groove. The top of each first spring is connected to a shock-absorbing plate. On both sides of the shock-absorbing plate, there are respectively an arc plate one and an arc plate two. The arc plate one, the shock-absorbing plate, and the arc plate two are sequentially spliced to form a semi-circular structure. The lower end of the arc plate one is connected to the bottom plate through a first column, and the lower end of the arc plate two is connected to the bottom plate through a second column.

[0004] The above patent slows down the vibration generated during transportation by setting a groove, a first spring, and a shock-absorbing plate to avoid the impact of vibration on the hydrogen storage tank; however, the disadvantages of the above patent are as follows: The overall structure is relatively bulky. At the same time, using the bottom plate as the overall support, its excessive weight will increase the transportation cost. At the same time, the hydrogen storage tank is directly placed on the shock-absorbing plate, and the head and tail ends of the hydrogen storage tank are fixed by the left and right frames respectively. There is not enough restraint in the length direction of the hydrogen storage tank, resulting in the hydrogen storage tank being easily disengaged from the length direction during transportation.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above defects. Content of the Utility Model

[0006] The purpose of the utility model is to provide a high-pressure hydrogen storage tank to solve the problems put forward in the above background technique.

[0009] Further, a plurality of protective beams are evenly spaced between the adjacent bottom main beam and the top main beam on the side of the protective bracket.

[0010] Further, the cross-section of the base square tube is square.

[0011] Still further, the cross-section of the sliding seat is in the shape of a C.

[0012] Further, a rectangular groove is also opened on the base square tube; at the same time, a first abutting plate is bent downward on one side of the sliding seat close to the rectangular groove; the first abutting plate extends upward into the rectangular groove, and a second abutting plate is also arranged inside the base square tube; the second abutting plate is connected to the first abutting plate by a shock absorber.
