In the process of preparing hydrogen, there is no need to frequently replace the hydrogen production tank 10 and the gas storage tank 7. The connection between the hydrogen production tank 10 and the gas storage tank 7 is automatically completed, with a high degree of automation and easy use.

[0036] In this embodiment, the hydrogen transfer drying assembly specifically includes: a drying chamber 13 opened inside the middle plate 4, a telescopic docking assembly is provided at an oblique angle between the top and bottom surfaces of the middle plate 4, the telescopic docking assembly located on the top surface of the middle plate 4 corresponds to the gas storage tank 7 on the far left, and the telescopic docking assembly located on the bottom surface of the middle plate 4 corresponds to the hydrogen production tank 10 on the far right, and a hydrogen drying mechanism is provided inside the drying chamber 13. The hydrogen transfer drying assembly provided can effectively dry the produced hydrogen for easy use.

[0037] In this embodiment, the telescopic docking assembly specifically includes: two parallel telescopic motors 14 fixed on the top and bottom surfaces of the middle plate 4, the output shafts of the two telescopic motors 14 are commonly fixedly connected to a support plate 15, and a gas guide pin 16 is embedded inside the support plate 15, a gas guide hose 17 is provided between the gas guide pin 16 and the middle plate 4, and one end of the gas guide hose 17 is connected to the gas guide pin 16, and the other end of the gas guide hose 17 is connected to the drying chamber 13 through a through hole 18. The telescopic docking assembly facilitates the rapid docking of the hydrogen production tank 10 and the gas storage tank 7.

[0038] In this embodiment, the hydrogen drying mechanism specifically includes: a sealing plate 25 arranged in the middle of the drying chamber 13, a rotating shaft 26 symmetrically fixedly connected to the center of the two sides of the sealing plate 25, and the sealing plate 25 is rotatably connected to the inner wall of the drying chamber 13 through the rotating shaft 26, a rectangular cavity 29 is opened inside the sealing plate 25, and the rectangular cavity 29 is filled with molecular sieve particles 30, the top and bottom surfaces of the sealing plate 25 are both opened with micropores 31 connected to the rectangular cavity 29, and angle adjustment parts are symmetrically provided at the edges of both sides of the top surface of the sealing plate 25. The hydrogen drying mechanism can effectively remove moisture from hydrogen and improve the quality of hydrogen.

[0039] In this embodiment, the angle adjustment member specifically includes: a strip metal plate 27 fixed to the edge of the top surface of the sealing plate 25, an electromagnet 28 is embedded at the position of the top surface of the drying chamber 13 corresponding to the strip metal plate 27, and the strip metal plate 27 matches the electromagnet 28. By setting the angle adjustment member, the moisture adsorption performance of the molecular sieve particles 30 in the sealing plate 25 can be effectively improved, and the quality of hydrogen can be improved.

[0040] The working principle of the present invention is: when in use, the hydrogen produced by fermentation in the hydrogen production tank 10 on the far right in the lower groove 3 enters the drying chamber 13 through the corresponding gas guide pins 16, gas guide hoses 17 and through holes 18. Subsequently, when the hydrogen and water vapor pass through the micropores 31 of the sealing plate 25, the molecular sieve particles 30 in the rectangular cavity 29 adsorb the moisture therein. After passing through the sealing plate 25, the hydrogen passes through another group of gas guide pins 16, gas guide hoses 17 and through holes 18 and enters the gas storage tank 7 on the far left in the upper groove 2. One gas storage tank 7 corresponds to one hydrogen production tank 10. After the fermentation of the hydrogen production tank 10 on the far right in the lower through slot 3 is completed, the gas storage tank 7 on the far left in the upper through slot 2 is also full of hydrogen. At this time, the hydrogen production tank 10 and the gas storage tank 7 are synchronously replaced by a synchronous asymmetric driving mechanism. The specific process is as follows: the telescopic motors 14 on the two telescopic docking assemblies are operated at the same time to retract the output shafts, so that the two gas guide pins 16 are respectively separated from the first rubber plug 19 and the second rubber plug 34. Subsequently, the stepping motor 24 is operated to drive the driving gear 22 in the driving slot 21 to rotate. The upper teeth 20 on the bottom end surfaces of the two side walls of the groove of the concave frame 5 and the lower teeth 23 on the top end surfaces of the two side walls of the groove of the second concave frame 8 are both engaged with the driving gear 22. Therefore, as the driving gear 22 rotates, the first concave frame 5 extends out of the upper through groove 2 to the left along the upper through groove 2, and the second concave frame 8 extends out of the lower through groove 3 to the right along the lower through groove 3. During this process, the first limiting linear guide 11 and the first linear guide slider 12 undergo relative displacement, and the second limiting linear guide 32 and the second linear guide slider 33 undergo relative displacement. After the first concave frame 5 and the second concave frame 8 move a preset distance, the second hydrogen production tank 10 on the right side of the lower through groove 3 arrives under one telescopic docking assembly, and the second gas storage tank 7 on the left side of the upper through groove 2 arrives above another telescopic docking assembly. Subsequently, the telescopic motor 14 of the telescopic docking assembly runs to extend the output shaft, driving the two gas guide pins 16 to penetrate the first rubber plug 19 and the second rubber plug 34 respectively and enter the corresponding gas storage tank 7 and hydrogen production tank 10, and start the next round of hydrogen preparation and collection.

[0041] It should be noted that, since the density of water vapor is greater than that of hydrogen, the water vapor entering the drying chamber 13 is absorbed more by the molecular sieve particles 30 at the bottom. In the long run, the adsorption effect of the molecular sieve particles 30 will decrease, and the overall moisture adsorption of the molecular sieve particles 30 will be uneven. For this reason, the present application improves the moisture adsorption performance of the molecular sieve particles 30 in the sealing plate 25 and improves the quality of hydrogen by setting an angle adjustment member. The specific process is as follows: in the initial state, the electromagnet 28 on the left side of the drying chamber 13 is not energized, and the electromagnet 28 on the right side is energized to generate magnetism. Therefore, the electromagnet 28 on the right side is firmly adsorbed with the strip metal plate 27 on the right side of the top surface of the sealing plate 25. When the angle of the sealing plate 25 needs to be adjusted, the electromagnet 28 on the left side is adjusted. The magnet 28 is energized to generate magnetism, and the electromagnet 28 on the right is disconnected from the power supply. At this time, the sealing plate 25 is lifted up by the magnetic adsorption force of the electromagnet 28 on the left, until the electromagnet 28 on the left is firmly adsorbed to the strip metal plate 27 on the left side of the top surface of the sealing plate 25. At this time, the angle of the sealing plate 25 is just reversed. The reversed sealing plate 25 not only changes one side to contact the water vapor, but also allows the molecular sieve particles 30 originally at the top to rotate to the bottom, and the molecular sieve particles 30 originally at the bottom to rotate to the top, thereby making the molecular sieve particles 30 absorb moisture more evenly and improving the adsorption effect. By repeatedly adjusting the angle of the sealing plate 25 in this way, the staff can keep the water absorption effect of the molecular sieve particles 30 in a good state.

[0042] In addition, after the four hydrogen production tanks 10 and the four gas tanks 7 are sent out, the staff can collect the hydrogen production tanks 10 after the reaction and the full gas tanks 7, and then take new hydrogen production tanks 10 and gas tanks 7 for replacement. During the replacement process, it is only necessary to snap the bottom of the hydrogen production tank 10 into the corresponding annular plate 9 and snap the gas tank 7 into the corresponding circular slot 6. Subsequently, after the fifth hydrogen production tank 10 and the gas tank 7 complete the hydrogen production and collection work, the stepper motor 24 drives the driving gear 22 in the driving groove 21 to rotate in the opposite direction, so that the new hydrogen production tank 10 and the gas tank 7 reach the telescopic docking assembly position. Through the hydrogen collection assembly, hydrogen preparation assembly and synchronous reverse driving mechanism, it is not only convenient to replace the hydrogen production tank 10 and the gas tank 7, but also can not affect the hydrogen preparation process, which is convenient for use. At the same time, it is not necessary to frequently replace the hydrogen production tank 10 and the gas tank 7 during the preparation of hydrogen, and the connection between the hydrogen production tank 10 and the gas tank 7 is automatically completed, with a high degree of automation and easy to use.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
