Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage technology, and more specifically, it relates to a hydrogen storage device based on magnesium-based solid hydrogen storage materials. Background Technology

[0002] Magnesium-based materials typically rely on hydrogen diffusion and adsorption during hydrogen storage. However, in existing technologies, the following factors limit the hydrogen absorption efficiency and slow hydrogen release rate: When adsorbing hydrogen, magnesium-based materials may form an oxide layer or other passivation layer on their surface, hindering hydrogen diffusion into the material and thus reducing hydrogen storage efficiency. Magnesium-based materials have relatively weak hydrogen diffusion capabilities, especially at lower temperatures, making it difficult for hydrogen to quickly enter the material, resulting in a slow hydrogen absorption rate and limited overall hydrogen storage capacity. Magnesium-based materials undergo exothermic or endothermic reactions during hydrogen absorption and release. If the device fails to effectively control the temperature, it may affect the hydrogen storage performance of the material, or even lead to local overheating or undertemperature, reducing hydrogen storage efficiency.

[0003] In existing hydrogen storage devices, magnesium-based tanks are typically installed in a fixed manner. However, the installation and disassembly process presents certain difficulties. Some hydrogen storage devices use bolts, clips, or other fixing methods, which require tools to disassemble and reassemble the magnesium-based tank during replacement or maintenance. This process is cumbersome, time-consuming, and labor-intensive. Since magnesium-based tanks are usually heavy and have limited space within the hydrogen storage device, their installation and disassembly are easily restricted by location, increasing the difficulty of operation. Existing installation methods fail to achieve efficient engagement and disengagement, resulting in a long time required to replace magnesium-based materials, which is detrimental to the efficient operation of the hydrogen storage system.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a hydrogen storage device based on magnesium-based solid hydrogen storage material, which has the following advantages:

[0017] This invention features a rotating adsorption mechanism. Through the design of the rotating shaft and rotating blades, the magnesium-based box can be easily rotated and positioned inside the device, thereby achieving a more efficient hydrogen storage process. This makes the adsorption process more stable, avoids the instability factors that may occur during manual operation, and improves the efficiency of the hydrogen storage system.

[0018] This invention features a base box snap-fit ​​mechanism, which securely connects the magnesium base box to the rotating blade. The meshing of the internal toothed ring and the corner teeth makes the snap-fit ​​process smoother and effectively prevents the magnesium base box from loosening or falling off during operation due to vibration or external forces, ensuring the safety and stability of the hydrogen storage device. By rotating the internal toothed ring, the corner teeth are rotated, allowing the insert block to smoothly extend into the annular groove and fix the snap-fit ​​rod inside the snap-fit ​​tube, achieving a quick and secure snap-fit. This simplifies the installation and disassembly process of the magnesium base box and improves the ease of operation.

[0019] This utility model is equipped with a locking auxiliary mechanism. Through the cooperation of components such as the outer rotating sleeve, rotating block, and spring rod, the locking auxiliary mechanism provides a stable effect of step-by-step locking. The step-by-step rotation mechanism of the outer rotating sleeve and the inner toothed ring can accurately lock the position of the rotating adsorption mechanism, so that the magnesium-based box remains stable during operation and avoids structural loosening or instability caused by improper operation or external factors. The design of the spring rod and rotating block effectively improves the reliability of the locking, so that the outer rotating sleeve and the inner toothed ring can maintain stability during long-term use and extend the service life of the equipment.

[0031] The locking auxiliary mechanism includes an outer rotating sleeve 14, a rotating block 15, a spring rod 16, a fixing ring 17, and insertion holes 18.

A tank cover 23 is installed at the top end of the outer shell 1, and a [missing information - likely a device name or design element] is installed on the tank cover 23. The discharge pipe 24 and the addition pipe 25 are provided. A connecting plate 26 is installed at the bottom of the side wall of the clamping pipe 7. Side plates 27 are installed at both ends of the magnesium-based box 6, and the connecting plate 26 is fixedly installed on the side plates 27. The clamping rod 8 is installed on the rotating page 5.

The clamping pipe 7 is provided in two sections, and a support rod 28 is fixedly installed between the two sections of the clamping pipe 7. The corner tooth 12 is rotatably installed on the support rod 28.

[0034] More specifically, after the motor starts, it drives the rotating page 5 to rotate via the rotating shaft 4, which in turn drives the magnesium-based box 6 to rotate. During this process, the magnesium-based box 6 adsorbs or releases hydrogen. The box locking mechanism, through the cooperation of the locking pipe 7 and the mating rod 9, ensures the fixed connection between the magnesium-based box 6 and the rotating page 5. The locking auxiliary mechanism ensures the stability and accuracy of this locking process, allowing the entire device to operate safely and reliably.

In addition, the design of the support legs 19 and bottom wheels 20 installed at the bottom of the outer shell 1 ensures the stability of the entire device during use. The design of the temperature and heating components 22 ensures temperature control within the device. When it is necessary to heat or adjust the temperature of the hydrogen storage material, these components can help the device operate under optimal conditions through heating and temperature measurement. The discharge pipe 24 and the addition pipe 25 on the tank cover 23 provide channels for the entry and exit of hydrogen, ensuring the effective transfer and storage of hydrogen.

[0035] In summary, during the use or operation of the overall equipment: when the adsorption mechanism needs to be rotated, the drive motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the rotating page 5 to rotate. The rotating page 5 is equipped with a magnesium-based box 6. Through the rotational movement, the magnesium-based material can fully contact the hydrogen gas, improving the hydrogen storage efficiency. The design of the inner shell 2 and the outer shell 1 forms a double-layer structure, which is beneficial for temperature control and safety assurance. Throughout the process, the temperature measuring component 21 and the heating component 22 can monitor and adjust the temperature conditions of the hydrogen storage process in real time.

[0036] When the base box snap-fit ​​mechanism is in operation, it is responsible for the installation and fixation of the magnesium base box 6.

The mating rod 9 is installed at the end of the snap-fit ​​rod 8, and an annular groove 10 is provided on its side. When fixation is required, the rotation of the internal tooth ring 11 drives the rotating corner tooth 12 to rotate, so that the rotating block 13 extends into the annular groove 10, thereby firmly fixing the snap-fit ​​rod 8 and the mating rod 9 inside the snap-fit ​​tube 7.

[0037] When the locking auxiliary mechanism is in operation, the connection between the outer rotating sleeve 14 and the inner toothed ring 11 enables precise control of the locking process. When the outer rotating sleeve 14 is rotated, the spring rod 16 on the rotating block 15 can enter the insertion hole 18 on the fixed ring 17 step by step to achieve step locking, ensuring that the rotation process of the inner toothed ring 11 is stable and controllable, thereby ensuring the reliability of the locking process.
