DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0025] As Figures 1 to 5As shown in the figure, a solid hydrogen storage device for outputting hydrogen at a constant temperature and pressure according to the present utility model includes:

[0026] A storage member 1 and a driving assembly. A support ring 2 is arranged in the inner cavity of the storage member 1. An installation member 3 is arranged inside the groove cavity of the support ring 2. The other end of the installation member 3 is coaxially provided with an auxiliary ring 4. The auxiliary ring 4 is arranged in the inner cavity of the storage member 1. Multiple positioning holes are arranged on the installation member 3. Hydrogen storage tank bodies 5 are respectively inserted and pulled out in the multiple positioning holes. The driving assembly is arranged on the storage member 1 and is used to drive the installation member 3 to drive the multiple hydrogen storage tank bodies 5 to perform flipping at the working positions.

[0027] A moving assembly is used to drive the installation member 3 to adjust the positions of the multiple hydrogen storage tank bodies 5 in the inner cavity of the storage member 1. By arranging the installation member 3 inside the groove cavity of the support ring 2 and arranging multiple positioning holes on the installation member 3, the space inside the storage member 1 can be effectively utilized to realize the compact storage of multiple hydrogen storage tank bodies 5, significantly improving the hydrogen storage density and the overall hydrogen storage capacity of the device. The design of this device reduces the demand for additional temperature and pressure regulating equipment, simplifies the system structure, reduces the maintenance cost and the initial investment, and has good economic benefits. This device can ensure the output of hydrogen at a constant temperature and pressure, avoiding problems such as hydrogen leakage or efficiency reduction caused by temperature and pressure fluctuations, enhancing the safety and stability of the device. The driving assembly enables the working positions of the hydrogen storage tank bodies 5 to be accurately adjusted and flipped, so that the hydrogen storage tank bodies 5 perform hydrogen storage and release at the same working position, increasing the convenience of operation and use. By means of the moving assembly, the position of the installation member 3 in the storage member 1 is adjusted. This design facilitates the complete movement of the hydrogen storage tank bodies 5 into the storage member 1 during storage or transportation to prevent collisions and protect equipment such as pressure gauges on the hydrogen storage tank bodies 5. The structure is compact, facilitating the centralized storage of multiple hydrogen storage tanks, and reducing the procurement cost of temperature and pressure regulating equipment.

[0028] Such as Figures 1 to 5As shown, as a preferred solution, the drive assembly includes a connecting member 6 disposed at one end of the inner cavity of the storage member 1. A drive shaft 7 is disposed in the through hole of the connecting member 6. A sector gear 8 is coaxially disposed at one end of the drive shaft 7. The other end of the drive shaft 7 is coaxially disposed at the output end of a servo motor 9. The servo motor 9 is disposed on the connecting member 6. An internal gear ring 10 is coaxially disposed inside the cavity of the support ring 2. The sector gear 8 is in meshing transmission connection with the internal gear ring 10. Each time the servo motor 9 is started, the sector gear 8 is driven by the drive shaft 7 to rotate and mesh with the internal gear ring 10, driving the mounting member 3 to flip by one station of the hydrogen storage tank body 5. Each time the servo motor 9 is started, the sector gear 8 and the limiting member 11 are driven by the drive shaft 7 to rotate 360°. The meshing transmission design of the servo motor 9, the sector gear 8 and the internal gear ring 10 ensures the accurate switching of the stations of the hydrogen storage tank body 5. Each time the servo motor 9 is started, only the sector gear 8 rotates a certain angle, precisely corresponding to the flipping of one station of the hydrogen storage tank body 5, thereby realizing the accurate selection of the hydrogen source, improving the automation degree and operation accuracy of the system. The coaxial setting of the drive shaft 7 and the servo motor 9 and the direct connection with the sector gear 8 ensure the smoothness and efficiency of power transmission, avoiding power loss and transmission error, facilitating the inspection and replacement of the hydrogen storage tank body 5 by maintenance personnel, and improving the overall operation efficiency. The setting of the connecting member 6 not only integrates the drive shaft 7 and the servo motor 9, but also provides a stable support point, simplifies the structural layout of the device, reduces the need for additional brackets, and further reduces the manufacturing cost and space occupation.

[0029] As Figures 1 to 5 shown, as a preferred solution, a limiting member 11 is coaxially disposed on the drive shaft 7. A plurality of inner arc grooves are equidistantly disposed on the internal gear ring 10. The inner arc grooves of the internal gear ring 10 correspond one by one to the positioning holes of the mounting member 3. The limiting member 11 is in sliding connection with the inner arc grooves of the internal gear ring 10. The correspondence between the limiting member 11 and the inner arc grooves on the internal gear ring 10 ensures the accuracy of the station switching of the hydrogen storage tank body 5. By ensuring that the mounting member 3 is in a locked state after the sector gear 8 disengages from the internal gear ring 10, the stable meshing of the sector gear 8 and the internal gear ring 10 next time is guaranteed, and at the same time, the free rotation of the mounting member 3 under non-driving by the driving wheel is prevented.

[0030] As Figures 1 to 5As shown, as a preferred embodiment, the moving assembly includes a transmission member 12 arranged in the axial hole of the connecting member 6, a threaded rod 13 is arranged in the threaded hole of the transmission member 12, one end of the threaded rod 13 is coaxially arranged on the mounting member 3, and the transmission member 12 provides rotational power through the power assembly. The solid-state hydrogen storage device for outputting hydrogen at a constant temperature and pressure is characterized in that a positioning member 14 is arranged on the connecting member 6, a guide groove is arranged on the threaded rod 13, and the positioning member 14 is arranged inside the guide groove of the threaded rod 13; the design of the moving assembly, especially the cooperation between the transmission member 12 and the threaded rod 13, can convert the rotational motion of the power assembly into linear motion, accurately adjust the position of the hydrogen storage tank body 5 in the inner cavity of the storage member 1, and the positioning member 14 is arranged in the guide groove of the threaded rod 13 to limit the rotation of the threaded rod 13, so as to prevent the threaded rod 13 from rotating synchronously driven by the transmission member 12.

[0031] like Figures 1 to 5 As shown, as a preferred solution, the power assembly includes a power shaft 15 arranged in the fixing hole of the connecting member 6, a driving gear 16 is coaxially arranged on the power shaft 15, a driven gear 17 is coaxially arranged on the transmission member 12, the driving gear 16 and the driven gear 17 are meshingly connected, the power shaft 15 is coaxially arranged at the output end of the driving motor 18, and the driving motor 18 is arranged on the connecting member 6; the meshing transmission design of the driving gear 16 and the driven gear 17 ensures the efficient transmission of power from the driving motor 18 to the transmission member 12, reduces energy loss, and the output of the driving motor 18 can be accurately adjusted by the gear ratio of the driving gear 16 and the driven gear 17, which means that the rotation speed and torque of the threaded rod 13 can be flexibly adjusted, thereby improving the flexibility and adaptability of the device.

[0032] like Figures 1 to 5 As shown, as a preferred solution, a mounting base 19 is provided at the bottom of the storage member 1, and a plurality of groups of Formosa wheels 20 are provided at the bottom of the mounting base 19; the provision of the Formosa wheels 20 significantly improves the mobility of the entire solid-state hydrogen storage device, so that the device can be easily transferred between different workplaces without the need for heavy handling equipment, thereby reducing the handling cost and labor intensity, which is particularly important in scenarios where the location of use needs to be changed frequently. The design of the Formosa wheels 20 and the mounting base 19 not only provides a stable support, but also enhances the load-bearing capacity of the storage member 1, ensuring that the device can remain stable whether in a moving or stationary state, and avoiding the risk of tipping over due to uneven ground or uneven load.

[0033] like Figures 1 to 5 As shown, as a preferred solution, a locking assembly is provided at the connection between the hydrogen storage tank body 5 and the positioning hole of the mounting member 3; the design of the locking assembly ensures a firm connection between the hydrogen storage tank body 5 and the mounting member 3, prevents the hydrogen storage tank from accidentally loosening during transportation, operation or vibration environments, and significantly enhances the overall safety and stability of the device.

[0034] As Figures 1 to 5 shown, as a preferred solution, its working process is as follows:

[0035] Before the device starts, first ensure that all hydrogen storage tank bodies 5 are correctly installed in the positioning holes of the mounting parts 3 and are safely locked through the locking components to ensure stable connection and good sealing. Check whether all parts of the device are in a normal state, including but not limited to the driving component, moving component, power component, etc., to ensure that there are no obstacles affecting its normal operation. The hydrogen storage tank bodies 5 are in the inner cavity of the receiving part 1 and are fixed through multiple groups of positioning holes of the mounting parts 3 to achieve the compact storage of multiple hydrogen storage tanks. Hydrogen is adsorbed or stored in the hydrogen storage tank bodies 5 under suitable temperature and pressure conditions. When the working positions of multiple groups of hydrogen storage tank bodies 5 need to be adjusted, the servo motor 9 starts, drives the sector gear 8 to rotate through the drive shaft 7, and then meshes with the internal gear ring 10 to turn the mounting part 3 and switch to the next working position of the hydrogen storage tank body 5. Under the precise control of the servo motor 9, after the sector gear 8 disengages from the internal gear ring 10, the limiting part 11 slides into the inner arc groove of the gear ring 10 to slide and lock the rotation of the mounting part 3. When the hydrogen storage tank body 5 needs to be received or used, the drive motor 18 in the power component starts, transmits the rotational power to the transmission part 12 through the meshing of the driving gear 16 and the driven gear 17, drives the threaded rod 13 to rotate, and realizes the adjustment of the position of the hydrogen storage tank body 5 in the inner cavity of the receiving part 1.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
