[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of a solid hydrogen storage device with a high-sealing safety valve, including:

[0036] Please see Figures 1-6 This embodiment of a solid hydrogen storage device with a high-sealing safety valve includes a bottle body 1. A buffer pad 27 is fitted to the bottom of the bottle body 1. A buffer rod 28 is welded to the bottom of the buffer pad 27. A buffer spring 29 is welded to the bottom of the buffer rod 28. A buffer seat 30 is welded to one end of the buffer spring 29. Through the fit between the buffer pad 27 and the bottle body 1, when the bottle body 1 is subjected to lateral pressure, the buffer spring 29 contracts to relieve the impact and transmits the force to the back plate 22, thereby reducing the lateral pressure on the bottle body 1. The back plate 22 is welded to the bottom of the buffer seat 30. A base 21 is welded to the bottom of the back plate 22. A top of the base 21 is welded to... There is a support rod 23, and a combination ring 24 is welded to the top of the support rod 23. The combination ring 24 is connected to the inside by a combination bolt 25 through a thread. The combination ring 24 is bonded and fixed with an anti-slip ring 26. By placing the bottle body 1 on the inner circumference of a combination ring 24, and then assembling the combination ring 24 into a complete combination ring 24 through the combination bolt 25, the bottle body 1 is installed inside and cooperates with the anti-slip ring 26 inside the combination ring 24. The anti-slip ring 26 is made of rubber. The rubber increases the friction between the anti-slip ring 26 and the barrier layer 13, thereby preventing the bottle body 1 from shifting its position over a large range. An inner lining layer 11 is welded to the outer circumference of the bottle body 1.

[0037] It is worth noting that, to prevent damage to the bottle 1 when dropped or impacted, specifically, a buffer layer 12 is welded to the outer circumference of the inner liner 11, a barrier layer 13 is welded to the outer circumference of the buffer layer 12, a fixing ring 14 is welded to the outer circumference of the barrier layer 13, and an airbag 15 is bonded and fixed to the bottom of the fixing ring 14. The inner liner 11 is made of aluminum alloy to provide basic protection, the buffer layer 12 is made of epoxy resin to withstand the main stress when the bottle 1 is impacted, and the barrier layer 13 is made of polyamide to block hydrogen diffusion. This structure, combined with the airbag 15, enhances the protective performance of the bottle 1 and prevents damage to the bottle. When the body 1 is damaged, an air inlet 17 is provided on the top of the airbag 15. A vent tube 16 is fixedly connected to the bottom of the airbag 15 by bolts. The two ends of the vent tube 16 are connected to the bottom of the two airbags 15, so that when the airbag 15 is inflated, the vent tube 16 can deliver air to the inside of the other airbag 15. A fixing block 20 is glued and fixed to the top of the airbag 15. A connecting rope 19 is glued and fixed to the outer circumference of the fixing block 20. A rubber plug 18 is glued and fixed to one end of the connecting rope 19. The bottom of the rubber plug 18 is embedded in the air inlet 17. After the airbag 15 is inflated, the air inlet 17 can be blocked by the rubber plug 18 to prevent the airbag 15 from leaking.

[0038] Next, in order to facilitate the discharge of hydrogen, specifically, a valve head 2 is fixedly connected to the top of the bottle body 1 by bolts, and a pin 3 is slidably connected inside the valve head 2.

[0039] Meanwhile, in order to prevent hydrogen from leaking into the external environment through the gap between the valve core 7 and the valve head 2, specifically, the valve core 7 is welded to the inner circumference of the valve head 2, and the first sealing ring 4 is bonded and fixed to the top of the valve core 7.

[0040] Furthermore, in order to seal the hydrogen gas when not in use, a steel ball 5 is slidably connected to the bottom of the first sealing ring 4. The first sealing ring 4 can continue to perform the sealing effect when the second sealing ring 8 loses its sealing effect due to aging or other reasons. The first sealing ring 4 and the second sealing ring 8 enhance the sealing effect. A connecting spring 6 is slidably connected to the bottom of the steel ball 5.

[0041] It is worth noting that, in order to enhance the sealing performance of the valve core 7, specifically, the valve core 7 is welded to one end of the connecting spring 6, and a second sealing ring 8 is fitted and fixedly connected inside the valve core 7. The gap between the valve core 7 and the bottle body 1 can be filled by the second sealing ring 8, thereby reducing the possibility of air leakage.

[0042] Finally, in order to improve the filtration effect of the bottle body 1, a secondary filter 10 is embedded and fixed in the inner circumference of the valve core 7, and a primary filter 9 is installed and fixed at the bottom of the secondary filter 10. The exhaust gas can be precisely filtered through the primary filter 9 and the secondary filter 10 to remove particulate dust, so that only gas can be discharged during the exhaust process.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-6 The solid hydrogen storage device with a high-sealing safety valve according to this embodiment is used as follows:

[0045] 1: When using this solid hydrogen storage device with a high-sealing safety valve, the cylinder 1 first needs to be installed inside the combination ring 24 to facilitate the use of the hydrogen storage tank by the staff. Align the bottom of the cylinder 1 with the inside of the buffer pad 27 and fit it in. At the same time, cover the other half of the combination ring 24 and use the combination bolt 25 to form a complete combination ring 24 to fix the cylinder 1. The buffer pad 27 and the buffer spring 29 cooperate to reduce the lateral pressure on the cylinder 1. At the same time, the inside of the combination ring 24 is fixedly connected with an anti-slip ring 26 to prevent the cylinder 1 from shifting significantly after it is fixed.

[0046] 2: An inner liner 11 is fixedly connected to the outer circumference of the bottle body 1. A buffer layer 12 is welded to the outer circumference of the inner liner 11. A barrier layer 13 is welded to the outer circumference of the buffer layer 12. Through the inner liner 11, the buffer layer 12 and the barrier layer 13, and with the airbag 15 outside the barrier layer 13, the bottle body 1 can be protected when it is impacted or accidentally dropped, reducing the force of the impact or drop, thereby preventing damage to the bottle body.

[0047] 3. When hydrogen needs to be released, the hydrogen in the storage cylinder carries some powder. First, the primary filter 9 intercepts most of the larger particles. Then, when it passes through the secondary filter 10, all micron and submicron-sized powder is completely captured by its microporous structure. Only pure hydrogen can flow out of the valve seat. When filling the cylinder with hydrogen, the process is reversed. High-purity hydrogen enters through the valve. The dual filters also prevent impurities that may be present in the external environment from entering the cylinder, protecting the hydrogen storage material.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
