Hydrogen energy is a recognized clean energy source. It is considered to be the most promising alternative to fossil fuels in the future due to its high energy density and zero carbon emissions. Hydrogen fuel cells use hydrogen, a chemical element, to make batteries that store energy. Its basic principle is the reverse reaction of water electrolysis, supplying hydrogen and oxygen to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons through an external load to the cathode.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6The utility model provides a technical solution: a high-strength hydrogen storage tank device, including a hydrogen storage tank body 1, a bearing seat 2 is installed at the bottom of the hydrogen storage tank body 1, and multiple groups of moving parts 3 are also arranged on the bottom of the bearing seat 2; multiple groups of positioning parts 4 are arranged inside the bearing seat 2, and the positioning parts 4 include support columns 5 slidably connected to the bearing seat 2, and a switching component is arranged between the bearing seat 2 and the multiple groups of support columns 5; when working, the switching component drives the multiple groups of support columns 5 to slide downward and drives the moving parts 3 to rise, so as to improve the stability of the hydrogen storage tank body 1.

[0024] Specifically, the high-strength hydrogen storage tank device includes a hydrogen storage tank body 1, wherein the hydrogen storage tank body 1 is a prior art, and an air inlet and outlet mechanism is arranged on the top of the hydrogen storage tank body 1, and its structure and working principle are not repeated here. At the same time, the hydrogen storage tank body 1 is made of alloy material and has a high hardness, so that the service life of the hydrogen storage tank body 1 can be improved, and it is suitable for wide promotion and use. A bearing seat 2 is installed at the bottom of the hydrogen storage tank body 1, which is used to support the entire hydrogen storage tank body 1 to meet work needs. A plurality of groups of moving parts 3 are also arranged on the bottom of the bearing seat 2. Specifically, the moving parts 3 include a plurality of groups of support rods fixedly connected to the bottom of the bearing seat 2, and a moving wheel is arranged on the bottom of each support rod, so that the hydrogen storage tank body 1 can be driven to slide, and the use effect is better.

[0025] And multiple groups of positioning members 4 are arranged inside the bearing seat 2, and the positioning members 4 include support columns 5 slidably connected to the bearing seat 2. When the support columns 5 touch the ground, the stability of the entire hydrogen storage tank body 1 during operation can be improved, so that the water level inside the hydrogen storage tank body 1 will not fluctuate, further meeting the work needs. A switching component is arranged between the bearing seat 2 and the multiple groups of support columns 5, so when in use, the moving member 3 and the support member can be switched by the switching component to meet the work needs. Therefore, when working, after the entire hydrogen storage tank body 1 is moved to a predetermined position by the moving member 3, it is necessary to use the switching component to fix the hydrogen storage tank body 1 to a predetermined position, and use the switching component to drive the multiple groups of support columns 5 to slide downward until the moving member 3 is driven to rise. At this moment, the multiple groups of support columns 5 will replace the moving member 3 to contact the ground, thereby achieving the effect of improving the stability of the hydrogen storage tank body 1, and can automatically switch the state of the hydrogen storage tank body 1, further meeting the work needs, and suitable for wide promotion and use.

[0026] In the embodiment provided by the utility model, the switching component includes a connecting frame 7 slidably connected to the bearing seat 2, and multiple groups of support columns 5 are fixedly connected to the connecting frame 7; a threaded rod 11 is rotatably connected to the bearing seat 2, and the threaded rod 11 drives the connecting frame 7 to slide downward through a transmission member. Therefore, during use, the threaded rod 11 is driven to rotate on the bearing seat 2, and the connecting frame 7 is driven to slide downward through the transmission member, thereby driving the multiple groups of support columns 5 to slide downward synchronously to meet work needs.

[0027] In the embodiment provided by the utility model, the transmission member includes a plurality of groups of connection blocks 8 fixedly connected to the connection frame 7, and each connection block 8 is fixedly connected with a transmission block 9; a plurality of groups of driving blocks 10 are also slidably connected to the support seat 2, each driving block 10 is intermittently abutted with the connection block 8, and the plurality of driving blocks 10 are fixedly connected through a connecting rod 15; and a threaded rod 11 is threadedly connected with one of the driving blocks 10.

During the rotation of the threaded rod 11, the driving block 10 is driven to slide, and during the sliding process of the driving block 10, it abuts against the force-bearing block, and as the driving block 10 continues to slide, it drives the force-bearing block to slide downward, thereby driving the connection frame 7 to slide downward, and driving the plurality of support columns 5 to slide downward through the connection frame 7, thereby fixing the hydrogen storage tank body 1.

[0028] In the embodiment provided by the utility model, a driving part 12 for driving the threaded rod 11 to rotate is provided on the bearing seat 2. Specifically, the driving part 12 can be a servo motor, which is installed on the bearing seat 2. The output end of the servo motor is rotatably connected to the threaded rod 11 through a coupling, and is used to drive the threaded rod 11 to rotate to meet working needs.

When the threaded rod 11 rotates in the opposite direction, the force block will be unlocked. Therefore, during use, the reset spring 14 restores the elastic deformation and drives the connecting frame 7 to slide upward. At this time, the moving part 3 contacts the ground, which facilitates the movement of the hydrogen storage tank body 1 and improves the use effect.

[0030] In the embodiment provided by the utility model, a non-slip pad 6 is provided on the bottom of each support column 5, so as to further improve the stability of the hydrogen storage tank body 1 during operation.
