Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage containers, and in particular to a protective hydrogen storage container provided with an anti-leakage monitoring structure. Background Art

[0002] With the continuous development and utilization of new energy sources, hydrogen energy, as a clean and efficient energy source, has gradually begun to be developed and utilized. The application fields of hydrogen energy include fuel cells, automobiles, aviation and aerospace, etc. A hydrogen fuel vehicle is a vehicle that uses hydrogen as its main energy source. Its powertrain is mainly composed of a fuel cell and an electric motor. By inputting hydrogen into the fuel cell, the electrons of the hydrogen atoms are blocked by the proton exchange membrane and are conducted from the negative electrode to the positive electrode through an external circuit, thereby generating electricity to drive the motor and drive the vehicle. It can be seen that when using hydrogen energy, whether it is carried or inflated and transported, hydrogen needs to be stored, and in order to avoid combustion or even explosion of hydrogen, the safety of hydrogen storage needs to be ensured;

[0003] Hydrogen storage containers in the prior art, such as the solid-state hydrogen storage container provided in the Chinese patent with the authorization announcement number CN 216361275 U, belong to the field of solid-state hydrogen storage technology. The solid-state hydrogen storage container includes a basic structure and a cooling mechanism. The basic structure includes a container body and a hydrogen storage tank, and the hydrogen storage tank is arranged in the container body. The cooling mechanism includes a first cooling component, a second cooling component and a connecting pipe. The first cooling component includes a first cooling pipe, a first spiral pipe and a water pipe. The first cooling pipe is arranged in the middle of the container body, the first spiral pipe is arranged on the side wall of the first cooling pipe, and the water pipe is arranged in the inner cavity of the first cooling pipe. The second cooling component includes a second cooling pipe and a second spiral pipe. The solid-state hydrogen storage container has a reasonable structural design and occupies a small space as a whole. While not occupying the actual hydrogen storage space, the triple cooling function effectively reduces the ambient temperature of the hydrogen storage tank during operation, thereby ensuring the normal operation of the hydrogen storage work;

[0004] Another example is a Chinese patent with authorization announcement number CN 103620293 B, which provides a hydrogen storage container, which uses a hydrogen storage material capable of storing hydrogen to store hydrogen. The hydrogen storage container includes: a hollow bushing, which has a bushing opening for guiding hydrogen and is used to store hydrogen; a hollow sub-tank, which is arranged on the inner side of the bushing and is used to accommodate the hydrogen storage material; a heat exchange tube, which is arranged on the inner side of the sub-tank and guides a heat exchange medium; a sub-tank support portion, which is used to support the end of the sub-tank at the bushing opening and support the end of the heat exchange tube; and a heat exchange medium passage, which is formed in a manner of penetrating the sub-tank support portion and is used to guide the heat exchange medium to the heat exchange tube.

[0005] However, combined with existing practical applications, it is found that the current hydrogen storage containers still have certain disadvantages when used, such as:

[0006] At present, in order to ensure production efficiency, most hydrogen storage containers are single-layer structures when in use. In the event of accidents such as collisions, they are prone to leakage, and due to collision and friction, they are prone to failure or even explosion, affecting safety. At the same time, it is not convenient to detect and alarm hydrogen leaks in time.

[0007] When using existing hydrogen storage containers, the fixing method and fixed position are single, which affects the installation efficiency, resulting in low overall assembly efficiency and affecting production and processing;

[0008] The current hydrogen storage containers have a single structure and fixed length, and have no buffer against internal cracking or even explosion, which is not conducive to ensuring safety.

[0009] Therefore, we propose a protective hydrogen storage container provided with an anti-leakage monitoring structure to solve the above-mentioned problems. Summary of the invention

[0053] In a specific application scenario, the inner top cover 2 and the outer top cover 3 are fixedly connected to the inner tank body 1 and the first outer shell 6 respectively by means of flange connection. At the same time, the top center and side of the outer top cover 3 are respectively provided with an air nozzle 4 and an air extraction hole 5, which are convenient for the use of air in and out, and convenient for setting a negative pressure on the interlayer between the inner tank body 1 and the first outer shell 6. A reinforcement ring 7 is fixedly installed on the inner side of the first outer shell 6. When the inner tank body 1 is placed inside the first outer shell 6, it can ensure that the inner tank body 1 fits with the first outer shell 6 through the reinforcement ring 7, thereby maintaining the stability of the structure.

[0054] Among them, the bottom bracket 9 is fixedly installed on the inner bottom side of the inner tank body 1, the upper and lower ends of the hydrogen storage medium 10 are fixed with a clamping seat 11, and the bottom of the hydrogen storage medium 10 is connected with the bottom bracket 9 through the corresponding clamping connection between the clamping seat 11, and a fixing ring 12 located inside the inner tank body 1 is provided on the outer side of the top of the hydrogen storage medium 10, and the top of the hydrogen storage medium 10 is clamped with a first connecting frame 13 and a second connecting frame 14 in sequence, and the sides of the first connecting frame 13 and the second connecting frame 14 are bolted to the fixing ring 12;

[0055] In a specific application scenario, by fixing the bottom bracket 9 at the inner bottom of the inner tank body 1, the hydrogen storage medium 10 can be clamped and fixed with the bottom bracket 9 through the clamping seat 11. At the same time, the top of the hydrogen storage medium 10 is clamped and connected to the first connecting frame 13 and the second connecting frame 14 through the clamping seat 11. When the first connecting frame 13 and the second connecting frame 14 are clamped, the first connecting frame 13 and the second connecting frame 14 can be bolted to the fixing ring 12 on the top side of the inner tank body 1, so as to fix the hydrogen storage medium 10 and facilitate the use of hydrogen storage.

[0056] Among them, the display panel 15 is embedded and installed on the top of the protective mechanism, and the inner side of the display panel 15 is installed with an air pressure sensor located in the interlayer between the inner tank body 1 and the protective mechanism, and the outer side of the display panel 15 is provided with a display screen, and the inner side of the display panel 15 is provided with a connecting tube 16, and the inner side of the connecting tube 16 is provided with a pop-up mechanism, and the pop-up mechanism includes: a slide bar 17, a first spring 19 and a display block 20, the slide bar 17 is slidably inserted in the inner side of the connecting tube 16, and a sealing gasket 18 is fixed to the outer side of the bottom of the slide bar 17, the slide bar 17 is sealed and fitted with the connecting tube 16 through the sealing gasket 18, the display block 20 is fixedly installed on the top of the slide bar 17, the first spring 19 is sleeved on the outer side of the slide bar 17, and the slide bar 17 forms an elastic structure on the inner side of the connecting tube 16 through the first spring 19;

[0057] In a specific application scenario, a display panel 15 is installed on the inner top of the first shell 6, and an air pressure sensor and a display screen are respectively arranged on the inner and outer sides of the display panel 15. The air pressure sensor can monitor the air pressure between the inner tank body 1 and the interlayer between the first shell 6 in real time. At the same time, when the internal air pressure changes, the sliding rod 17 on the inner side of the connecting tube 16 will slide outward under the elastic action of the first spring 19, and the sliding rod 17 maintains a sealed fit with the connecting tube 16 through the sealing gasket 18 to avoid air pressure leakage, and is directly detected by machinery for easy observation.

[0058] The second spring 22 is fixedly installed on the inner bottom of the first shell 6, and the top of the second spring 22 is connected to the top block 21. The bottom of the inner tank body 1 fits the top block 21, and the first hoop 23 is wrapped around the outer side of the first shell 6.

[0059] In a specific application scenario, when disassembly is required, through the elastic action of the second spring 22, after disassembly between the outer top cover 3 and the first outer shell 6, the inner tank body 1 can be ejected through the top block 21, and at the same time, the outer side of the first outer shell 6 can be installed and used through the first hoop 23 to facilitate installation.

[0060] Based on the above description, when the hydrogen storage container is used, the bottom bracket 9 is first welded and fixed at the inner bottom of the inner tank body 1, and then the hydrogen storage medium 10 is correspondingly engaged with the bottom bracket 9 through the clamping seat 11 at the bottom end thereof, and the first connecting frame 13 and the second connecting frame 14 are sequentially engaged at the top of the hydrogen storage medium 10, so that the ends of the first connecting frame 13 and the second connecting frame 14 can be bolted to the fixing ring 12 fixed at the inner top of the inner tank body 1 to ensure the stable installation of the hydrogen storage medium 10 inside the inner tank body 1, and then the inner tank body 1 and the inner top cover 2 are correspondingly flange-sealed;

[0061] The bottom of the inner tank body 1 is sunk into the first outer shell 6 so that the inner tank body 1 as a whole extends into the first outer shell 6, and then the first outer shell 6 and the outer top cover 3 are correspondingly connected by flange sealing;

[0062] After the installation is completed, the interlayer between the inner tank body 1 and the first outer shell 6 is negatively adsorbed through the air extraction hole 5 connected to the top of the outer top cover 3, so that the interlayer between the inner tank body 1 and the first outer shell 6 forms a negative pressure space. When the internal air pressure of the inner tank body 1 and the first outer shell 6 decreases, the connecting tube 16 on the inner side of the display panel 15 and the sliding rod 17 inside thereof will be tightly fitted with the connecting tube 16 through the sealing gasket 18, so that the sliding rod 17 slides toward the inner side of the interlayer, so that the display block 20 at the top of the sliding rod 17 slides toward the inner side of the connecting tube 16, so that the display block 20 does not protrude from the outer side of the first outer shell 6, and then hydrogen is injected into the inner side of the inner tank body 1 through the gas nozzle 4 for storage;

[0063] When installation is required, the first housing 6 can be connected, installed and fixed via the first hoop 23 on the outside of the first housing 6;

[0064] When cracks are generated inside to form a leak, the air pressure in the interlayer between the inner tank body 1 and the first shell 6 changes, and the air pressure is detected by the air pressure sensor installed inside the interlayer inside the display panel 15, which can be displayed on the display screen outside the display panel 15. The change in air pressure will cause the slide bar 17 to slide, causing the display block 20 to slide outwards through the elastic action of the first spring 19, and then the display block 20 protrudes outwards to give a warning;

[0065] When disassembly is required, the outer top cover 3 and the first outer shell 6 are disassembled. After the disassembly is completed, the top block 21 pops up under the elastic action of the second spring 22 at the bottom of the inner side of the first outer shell 6, thereby lifting the inner tank body 1, so as to facilitate the quick disassembly of the inner tank body 1 from the first outer shell 6; Example

[0066] The difference from Example 1 is that, please refer to Figure 4-11 The present invention provides a technical solution: a protective hydrogen storage container with an anti-leakage monitoring structure, comprising: an inner tank body 1, an inner top cover 2, an outer top cover 3, a gas nozzle 4, an air extraction hole 5, a reinforcement ring 7, a flow hole 8, a bottom bracket 9, a hydrogen storage medium 10, a card seat 11, a fixing ring 12, a first connecting frame 13, a second connecting frame 14, a display board 15, a connecting tube 16, a sliding rod 17, a sealing gasket 18, a first spring 19, a display block 20, a top block 21, a second spring 22, a second shell 24, a third shell 25, a fourth shell 26, a buffer belt 27, a clamping ring 28, a first fixing seat 29, a buckle 30, a second fixing seat 31, a fixing buckle 32, a connecting seat 33, a second hoop 34 and a connecting buckle 35;

[0067] Among them, the protection mechanism is a second shell 24, a third shell 25 and a fourth shell 26. The top of the second shell 24 is connected to the corresponding flange of the outer top cover 3, and the bottom of the second shell 24 is connected to the third shell 25 and the fourth shell 26 in sequence. The connection method between the second shell 24 and the third shell 25 is the same as the connection method between the third shell 25 and the fourth shell 26. The contact ends of the second shell 24, the third shell 25 and the fourth shell 26 are all stepped structures. A buffer belt 27 is welded and fixed between the second shell 24 and the third shell 25 and between the third shell 25 and the fourth shell 26. A snap ring 28 is protruded from the outer side of the contact end of the second shell 24, the third shell 25 and the fourth shell 26. A first fixing seat 29 is sleeved on the outer side of the bottom of the shell 25, and a second fixing seat 31 is sleeved on the top of the third shell 25 and the fourth shell 26. A buckle 30 is provided at the bottom gap between the first fixing seat 29 and the second fixing seat 31. The first fixing seat 29 and the second fixing seat 31 are correspondingly fitted with the snap ring 28, and the first fixing seat 29 and the second fixing seat 31 are fitted with each other through the buckle 30. The buckle 30 is in an "L"-shaped structure. A fixing buckle 32 is snap-connected on the outer side of the buckle 30. The fixing buckle 32 monomers are fixedly connected by corresponding bolts, and a connecting seat 33 is fixedly installed on the outer side of the fixing buckle 32. A second hoop 34 is provided on the outer side of the connecting seat 33, and the second hoop 34 is snap-connected with the connecting seat 33 through the connecting buckle 35.

[0068] In a specific application scenario, the difference from Example 1 is that the first shell 6 is replaced by the second shell 24, the third shell 25 and the fourth shell 26, and the contact between the second shell 24 and the third shell 25 is a stepped structure, the buffer belt 27 is pasted on the inner side of the stepped structure, and a snap ring 28 is provided at the end of the second shell 24, the third shell 25 and the fourth shell 26, which is engaged by the first fixing seat 29 or the second fixing seat 31, so that the snap 30 on the inner side of the first fixing seat 29 and the second fixing seat 31 fits, and the fixing buckle 32 is engaged with the snap 30, so that after the fixing buckle 32 monomers are fixed, the second hoop 34 can be connected by the engagement between the connecting seat 33 and the connecting buckle 35, so as to facilitate assembly and use;

[0069] Based on this embodiment, when the hydrogen storage device leaks or even explodes, the internal gas will leak into the gap between the second shell 24, the third shell 25 and the fourth shell 26, causing the buffer belt 27 to swell outward, thereby causing the fixing buckle 32 to directly split. When the second shell 24, the third shell 25 and the fourth shell 26 are separated, the buffer belt 27 can buffer the gas leakage through its elastic structure to avoid explosion.
