Description

Technical Field

[0001] This utility model relates to the field of collection tank technology, specifically to a collection tank for water electrolysis hydrogen production that is easy to prevent leakage. Background Technology

[0002] Hydrogen production by water electrolysis is a method of producing hydrogen by electrolyzing water. As an intermediate link in hydrogen energy storage, it can convert excess renewable energy electricity into hydrogen for storage. When needed, it can generate electricity through fuel cells, realizing an "electricity-hydrogen-electricity" cycle. It is a key technology connecting renewable energy and hydrogen energy utilization.

[0003] In the process of hydrogen production by water electrolysis, it is necessary to collect the generated hydrogen. The collection of hydrogen is a critical step in the hydrogen production process. The collection process is as follows: the hydrogen generated at the cathode enters the gas-liquid separator through a pipeline, then passes through a water washing tower to absorb residual alkaline mist, and then passes through a dryer to remove water vapor before entering the collection tank for collection. The sealing of the collected hydrogen is particularly important. Currently, the collection tanks used for hydrogen production by water electrolysis are usually made of corrosion-resistant materials such as stainless steel, and the joints are strictly sealed to prevent leakage and the formation of explosive mixtures. However, the existing collection tanks usually monitor hydrogen leakage in the collection area by installing hydrogen concentration detectors, which is not convenient for accurately locating the leaking joints and implementing leak prevention measures, resulting in poor leak prevention effect.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figures 1 to 4A leak-proof collection tank for hydrogen production via water electrolysis includes a tank body 1, collection pipes 2, metal pads 3, a fixing frame 4, a drive column 5, a hydrogen concentration detector 6, a leak-proof ring 7, and leak-proof components. Multiple collection pipes 2 are arranged in a circular array and connected at the top of the tank body 1, allowing for rapid and omnidirectional collection of hydrogen produced by water electrolysis. The surfaces of the tank body 1 and the collection tank can be plated with nickel or chromium to prevent hydrogen penetration and extend the service life of the tank body 1 and collection pipes 2. The metal pads 3 are fixedly fitted onto each collection pipe 2 and are detachably connected to the tank body 1, reducing hydrogen leakage during collection. The fixing frame 4 is detachably mounted on the upper side of the tank body 1 via a fixing seat. The drive column 5 is rotatably mounted on the fixing frame 4. The hydrogen concentration detector 6 is installed on one side of the drive column 5. Furthermore, the hydrogen concentration detector 6 is located between multiple collection pipes 2, facilitating real-time monitoring of hydrogen leaks in these pipes. The alarm threshold of the hydrogen concentration detector 6 is typically set to 20% of the lower explosive limit. Simultaneously, the hydrogen concentration detector 6 is electrically connected to an alarm via a sensor, enabling timely alerts to personnel in case of a leak. Two anti-leakage rings 7 are provided, each located on one side of the hydrogen concentration detector 6. Sealing gaskets and sealing rings are fixedly connected to the sidewalls and bottom ends of the anti-leakage rings 7, respectively. The sealing gaskets ensure stable sealing contact between the two anti-leakage rings 7, while the sealing rings ensure a sealed contact between the anti-leakage rings 7 and the top of the tank 1, thus creating a sealed space at the leak point for timely leak prevention measures. The anti-leakage assembly is positioned between the two anti-leakage rings 7.

[0047] refer to Figure 3 as well as Figure 4 The leak-proof component includes a support plate 8, an electric push rod 10, a driven frame 11, a dual-head motor 12, a screw 13, and a moving plate 14. A support frame 9 is fixedly connected between the support plate 8 and the drive column 5. The electric push rod 10 is installed on the top of the support plate 8. The driven frame 11 is movably positioned on the lower side of the support plate 8, and the output end of the electric push rod 10 is fixedly connected to the driven frame 11. The dual-head motor 12 is installed on the driven frame 11 and is set to automatically perform forward and reverse rotation. There are two screws 13, which are symmetrically connected to the output end of the dual-head motor 12. The two screws 13 are respectively provided with threads in opposite directions. The moving plate 14 is threadedly connected to each screw 13 and is fixedly connected to the adjacent leak-proof ring 7. A moving block 26 is fixedly connected to one side of the moving plate 14. A moving groove for the moving block 26 to slide is provided on the driven frame 11, which increases the stability of the moving plate 14 moving on one side of the driven frame 11.

[0048] When a leak occurs, the hydrogen concentration detector 6 is rotated at a certain angle, and the support plate 8 rotates to be directly above the leaking collection pipe 2. The two anti-leakage rings 7 are positioned on both sides of the collection pipe 2. Then, the electric push rod 10 is activated, causing the driven frame 11 to move downward. When the anti-leakage rings move to the appropriate position and the sealing ring contacts the top of the tank 1, the dual-head motor 12 is activated, causing the two moving plates 14 to move in opposite directions through the rotation of the two screws 13. This allows the two anti-leakage rings 7 to surround the leaking collection pipe 2, forming a sealed space and reducing further hydrogen leakage. This improves the safety of collecting hydrogen produced by water electrolysis.

[0049] refer to Figure 1 as well as Figure 3 A connecting assembly is installed between the hydrogen concentration detector 6 and the drive column 5. The connecting assembly includes a connecting column 15, a connecting plate 16, a connecting block 17, and connecting screws 18. The connecting column 15 is fixedly connected to one side of the drive column 5, the connecting plate 16 is fixedly connected to the connecting column 15, and the connecting block 17 is detachably connected to one side of the connecting plate 16. The hydrogen concentration detector 6 is installed on the connecting block 17. Multiple connecting screws 18 are provided, and multiple connecting screws 18 are threaded between the connecting block 17 and the connecting plate 16.

[0050] By tightening multiple connecting screws 18 between the connecting plate 16 and the connecting block 17, the hydrogen concentration detector 6 can be stably installed on the connecting plate 16. Thus, the drive column 5 can stably rotate the hydrogen concentration detector 6 through the connecting column 15, the connecting plate 16 and the connecting block 17, so that the hydrogen concentration detector 6 can sequentially monitor the leakage of multiple collection tubes 2.

[0051] refer to Figure 3 The fixing base includes fixing strips 19, fixing plates 20, and fixing screws 21. Multiple fixing strips 19 are provided, and all of them are fixedly connected to the fixing frame 4. The fixing plate 20 is fixedly connected between the multiple fixing strips 19. The fixing plate 20 has a drive groove for the drive column 5 to rotate, which improves the stability of the drive column 5 rotation. Multiple fixing screws 21 are provided, and all of them are threadedly connected between the tank body 1 and the multiple fixing strips 19.

[0052] When the fixing plate 20 and multiple fixing strips 19 are placed on the top of the tank body 1, multiple fixing screws 21 are tightened between the tank body 1 and the multiple fixing strips 19, which increases the stability of the fixing strips 19, fixing plate 20 and fixing bracket 4 on the tank body 1.

[0053] refer to Figure 1 as well as Figure 3 A drive motor 22 is installed at the top of the fixed frame 4, and the output end of the drive motor 22 passes through the fixed frame 4 and is fixedly connected to the drive column 5.

[0054] When the drive motor 22 starts, the drive column 5 will rotate on the fixed frame 4, which will drive the support frame 9, support plate 8, connecting column 15, connecting plate 16 and connecting block 17 to rotate, thereby rotating the hydrogen concentration detector 6 and the anti-leakage ring, so that the hydrogen concentration detector 6 rotates sequentially among multiple collection tubes 2 for real-time monitoring.

[0055] refer to Figure 3 as well as Figure 4 Two symmetrically connected stabilizer cylinders 23 are connected to the support plate 8. A stabilizer rod 24 is connected through the stabilizer cylinder 23. The stabilizer rod 24 passes through the support plate 8 and is fixedly connected to the driven frame 11. A stabilizer bar is connected through the stabilizer rod 24. A stabilizer groove is provided on the stabilizer cylinder 23 for the stabilizer bar to slide.

[0056] When the driven frame 11 moves under the support plate 8, the two stabilizer bars 24 will move in the two stabilizer cylinders 23 respectively, and the stabilizer bar will move in the stabilizer groove, which increases the stability of the stabilizer bars 24 moving in the stabilizer cylinders 23. Thus, the two stabilizer bars 24 can make the driven frame 11 move smoothly, and in turn, make the anti-leakage ring 7 move smoothly.

[0057] refer to Figure 1 as well as Figure 2 The metal pad 3 has a through-hole that matches the collection pipe 2, and the metal pad 3 is threadedly connected to the top of the tank 1 with multiple mounting screws 25.

[0058] Multiple mounting screws 25 are tightened between the metal pad 3 and the tank 1 to facilitate the stable installation of the metal pad 3 and the collection pipe 2 on the tank 1, thereby improving the stability of hydrogen collection generated by water electrolysis. At the same time, the metal pad 3 can improve the sealing during collection and reduce leakage.

[0059] In summary, this leak-proof collection tank for hydrogen production via water electrolysis allows the drive motor 22 to rotate the drive column 5, which in turn causes the connecting column 15, connecting plate 16, and connecting block 17 to rotate. Simultaneously, the hydrogen concentration detector 6 monitors multiple collection pipes 2 for leaks. When the hydrogen concentration detector 6 detects a leak at the connection between a collection pipe 2 and the tank body 1, the drive motor 22 rotates the driven frame 11 to directly above the leaking collection pipe 2. At the same time, the dual-head motor 12 rotates the two screws 13 simultaneously, causing the two moving plates 14 to move the two leak-proof rings 7 in opposite directions. This allows the two leak-proof rings, two sealing gaskets, and two sealing rings to surround the leak, forming a sealed space and thus reducing further hydrogen leakage.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
