[0002] Hydrogen is a clean and efficient energy source that can be used in fuel cell power generation, fuel cell vehicles and other fields. Hydrogen storage refers to storing hydrogen in a certain form so that it can be released as an energy supply when needed. Currently commonly used hydrogen storage methods include compressed hydrogen, liquid hydrogen and solid hydrogen. Solid hydrogen is the adsorption or storage of hydrogen in solid materials to achieve high-density hydrogen storage.

[0003] The above-mentioned and prior arts have the following defects: in the process of storing hydrogen, the storage tank will release heat to the outside. In order to improve the heat dissipation effect of the storage tank and improve the hydrogen storage efficiency, a heat sink for auxiliary heat dissipation will be installed on the outer wall of the storage tank. However, after the hydrogen is stored, when the temperature of the environment around the storage tank is high, the external heat can easily heat the solid material in the storage tank through the storage tank or the heat sink, which can easily cause hydrogen to precipitate from the solid material, thereby reducing the storage efficiency of hydrogen.

[0029] like Figure 1-Figure 4As shown, the utility model provides a high-efficiency hydrogen storage device, including a storage tank 1, the upper end of the storage tank 1 is fixed and connected with a three-way valve 2, the lower surface of the storage tank 1 is fixedly connected with a heat insulation pad 4, the surface of the heat insulation pad 4 is fixedly connected with a heat insulation shell 3, the storage tank 1 is located in the heat insulation shell 3, the surface of the storage tank 1 is fixedly sleeved with a heat insulation ring 5, the heat insulation ring 5 is fixedly connected to the heat insulation shell 3, the arc surface of the heat insulation shell 3 is fixed and connected with a liquid inlet pipe 6, the arc surface of the heat insulation shell 3 is fixed and connected with a liquid discharge pipe 7, the surface of the liquid discharge pipe 7 is fixedly connected with a valve 8, and the arc surface of the heat insulation shell 3 is fixedly connected with a plurality of heat sinks 9. With the cooperation of the heat insulation ring 5 and the heat insulation pad 4, a cavity will exist between the storage tank 1 and the heat insulation shell 3, thereby preventing the external heat from being directly conducted to the storage tank 1 through the heat insulation shell 3, thereby preventing The solid material in the storage tank 1 is heated, resulting in rapid precipitation of hydrogen, thereby improving the storage efficiency of hydrogen. A protective strip 10 is fixedly connected to the surface of the heat sink 9, and the protective strip 10 is a rubber strip. During the transportation of the storage tank 1, the protective strip 10 can prevent the heat sink 9 from being damaged. A strip plate 11 is fixedly connected to the outer wall of the heat insulation shell 3, and a sliding frame 12 is slidably connected to the surface of the strip plate 11. An arc plate 13 is fixedly connected to the surface of the sliding frame 12, and a plurality of scrapers 14 are fixedly connected to the surface of the arc plate 13. The scraper 14 is slidably connected to the heat sink 9. The movement of the arc plate 13 will drive the scraper 14 to move. When the scraper 14 contacts the heat sink 9, the scraper 14 can quickly clean the surface of the heat sink 9, thereby ensuring that the heat sink 9 can dissipate heat normally.

[0030] like Figure 1-Figure 4 As shown, a guide block 15 is fixedly connected to the upper end of the strip plate 11, and the guide block 15 can guide the slide frame 12, so that the slide frame 12 is conveniently sleeved on the surface of the strip plate 11. The inner wall of the liquid inlet pipe 6 is rotatably connected to the liquid inlet bucket 16. When water is poured into the liquid inlet bucket 16, the water will flow into the liquid inlet pipe 6 through the liquid inlet bucket 16. The arc surface of the liquid inlet pipe 6 is fixedly connected to a rectangular plate 17, and a plunger 18 is slidably connected in the rectangular plate 17. The arc surface of the liquid inlet bucket 16 is fixedly connected to a perforated plate 19, and the plunger 18 is engaged with the perforated plate 19. When the plunger 18 is inserted into the perforated plate 19, the plunger 18 reaches the position of limiting the orifice plate 19, thereby limiting the position of the liquid inlet bucket 16. The arc surface of the plunger 18 is fixedly connected to two baffles 20, and the rectangular plate 17 is located between the two baffles 20. During the sliding process of the plunger 18, the baffle 20 prevents the plunger 18 from being out of contact with the rectangular plate 17.

[0031] The overall working principle is that when hydrogen needs to be added to the storage tank 1, the liquid inlet hopper 16 is rotated upward so that the opening of the liquid inlet hopper 16 faces upward. At this time, the inner wall of the liquid inlet hopper 16 will be aligned with the inner wall of the liquid inlet pipe 6, and then the plunger 18 is slid along the rectangular plate 17. When the plunger 18 is inserted into the orifice plate 19, the plunger 18 reaches the position of the orifice plate 19, thereby limiting the position of the liquid inlet hopper 16. During the sliding process of the plunger 18, the baffle 20 prevents the plunger 18 from being out of contact with the rectangular plate 17. Then, water is poured into the liquid inlet hopper 16, and the water It will flow into the liquid inlet pipe 6 through the liquid inlet hopper 16, and then flow into the space between the insulation shell 3 and the storage tank 1 through the liquid inlet pipe 6. When the water fills the space between the insulation shell 3 and the storage tank 1, the hydrogen is injected into the storage tank 1 with the help of the three-way valve 2. In this process, the solid material in the storage tank 1 will release heat, and the heat will be transferred to the insulation shell 3 through the storage tank 1 and the water. At the same time, the heat sink 9 can assist in transferring the heat in the insulation shell 3 to the outside. When the filling is completed, the valve 8 is opened to discharge the water through the drain pipe 7. At this time, with the cooperation of the insulation ring 5 and the insulation pad 4, the storage tank 1 There will be a cavity between the heat insulation shell 3, thereby preventing the external heat from being directly transferred to the storage tank 1 through the heat insulation shell 3, thereby preventing the solid material in the storage tank 1 from being heated, resulting in the rapid precipitation of hydrogen, and improving the storage efficiency of hydrogen. After that, the plug rod 18 is pulled out from the orifice plate 19, and the liquid inlet hopper 16 will rotate downward 180 degrees due to its own weight. At this time, the inner wall of the liquid inlet hopper 16 will be misaligned with the inner wall of the liquid inlet pipe 6, so that the liquid inlet hopper 16 will block the liquid inlet pipe 6. When it is necessary to clean the surface of the heat sink 9, move the curved plate 13. The movement of the arc plate 13 will drive the sliding frame 12 to move, and then the sliding frame 12 will be placed on the surface of the strip plate 11. During this process, the guide block 15 can guide the sliding frame 12 to facilitate the sliding frame 12 to be placed on the surface of the strip plate 11. The movement of the arc plate 13 will drive the scraper 14 to move. When the scraper 14 contacts the heat sink 9, the scraper 14 can quickly clean the surface of the heat sink 9, thereby ensuring that the heat sink 9 can dissipate heat normally. In the process of transporting the storage tank 1, the protective strip 10 can prevent the heat sink 9 from being damaged.
