[0002] A photovoltaic (PV) power station, also known as a solar power station, refers to a large-scale power facility that directly converts solar radiation energy into electrical energy using the photovoltaic effect. Its core component is the photovoltaic module, which consists of numerous photovoltaic cells connected in series and parallel. These modules absorb sunlight and generate direct current (DC).

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] This utility model provides a technical solution: such as Figures 1-5 As shown in this embodiment, a green hydrogen production device for a photovoltaic power station includes a hydrogen production tank 1. A filter tank 3 and a gas separation tank 7 are fixedly connected to the hydrogen production tank 1. Both the filter tank 3 and the gas separation tank 7 are connected to the interior of the hydrogen production tank 1. A liquid injection port 5 is provided at the top of the filter tank 3, and a filter groove 23 is provided on one side of the filter tank 3. A filter frame 4 is slidably connected between the inner walls of the filter groove 23. An oxygen outlet pipe 9 and a hydrogen outlet pipe 10 are fixedly connected to the top of the gas separation tank 7. Both the oxygen outlet pipe 9 and the hydrogen outlet pipe 10 are connected to the interior of the gas separation tank 7. A photovoltaic panel 8 is installed on the top of the gas separation tank 7, and a guide groove 24 is provided on one side of the gas separation tank 7. A gas separation... A sealing structure is provided on one side of the gas separation box 7, which is used to seal the guide groove 24. An isolation plate 20 is fixedly connected between the inner walls of the gas separation box 7. A storage battery 2 is provided on one side of the hydrogen production box 1. An anode block 17 and a cathode block 18 are provided on one side inside the hydrogen production box 1. Both the anode block 17 and the cathode block 18 are electrically connected to the storage battery 2. Control valves 12 are provided on the outer sides of the oxygen outlet pipe 9 and the hydrogen outlet pipe 10. A compressor 11 is fixedly installed on the top of the gas separation box 7. The hydrogen outlet pipe 10 passes through the compressor 11. An observation port 6 is provided on one side of the hydrogen production box 1. A groove 26 is opened on the top of the gas separation plate 19. The inner side of the groove 26 is slidably connected to the bottom of the isolation plate 20.
[0024] In the green hydrogen production process at a photovoltaic power station, the electrolyte (specifically a mixture of distilled water and sodium hydroxide, effectively improving electrolysis efficiency) is first injected into the filter box 3 through the injection port 5. Next, impurities are filtered from the electrolyte through the filter frame 4 inside the filter tank 23 (the bottom of the filter frame 4 is made of stainless steel to ensure corrosion resistance and high strength). The electrolyte then flows into the hydrogen production tank 1. Then, the gas separation plate 19 (containing a target membrane and a polyvinyl fluoride membrane; hydrogen permeates through the target membrane while isolating oxygen, and oxygen permeates through the polyvinyl fluoride membrane while isolating hydrogen) is inserted into the guide groove 24, ensuring the inner side of the groove 26 contacts the isolation plate 20. The guide groove 24 is sealed by a sealing structure, and the gas separation plate 19 is fixed. At the same time, the photovoltaic panel 8 converts light energy into electrical energy, which is stored in the battery 2 and then provides power to the anode block 17 and the cathode block 18, so that the anode block 17 and the cathode block 18 react with the electrolyte to produce oxygen and hydrogen respectively. The preparation process is observed through the observation port 6. Then, the oxygen and hydrogen enter the interior of the gas separation box 7 and are separated by the gas separation plate 19. The oxygen is discharged and collected along the oxygen outlet pipe 9, while the hydrogen is compressed by the compressor 11 and discharged along the hydrogen outlet pipe 10 for collection and use. At the same time, the discharge amount of oxygen and hydrogen can be controlled by two control valves 12 to ensure safe discharge.
[0025] When it is necessary to remove the gas separation plate 19, after oxygen and hydrogen have been completely removed, the gas separation plate 19 is released through the sealing structure and then taken out, thereby improving the performance of the green hydrogen preparation device.
[0026] like Figures 1-5 As shown, the sealing structure includes a sealing box 13, which is fixedly connected to one side of the gas separation box 7. A sliding plate 27 is slidably connected between the inner walls of the sealing box 13. A through groove 25 is provided at the bottom of the sealing box 13. A connecting plate 21 is slidably connected between the inner walls of the through groove 25. A sealing plate 15 is fixedly connected to the bottom of the connecting plate 21. The sealing plate 15 abuts against one side of the gas separation plate 19. A sliding groove 14 is provided on one side of the sealing box 13. A lever 16 is slidably connected between the inner walls of the sliding groove 14. One side of the lever 16 is fixedly connected to the sliding plate 27. A return spring 22 is provided between the sliding plate 27 and the inner side of the sealing box 13.
[0027] By pushing the paddle 16 to move between the inner walls of the slide groove 14, the sliding plate 27 is moved between the inner walls of the sealing box 13, and the return spring 22 (specifically made of high carbon steel) is compressed. Then, the connecting plate 21 is moved between the inner walls of the through groove 25, and the sealing plate 15 is moved away from the gas separation plate 19, thereby releasing the fixation of the gas separation plate 19.
[0028] The spring force of the return spring 22 pushes the connecting plate 21 to move between the inner walls of the through groove 25, and drives the sealing plate 15 to contact the gas separation plate 19, thereby completing the fixation of the gas separation plate 19 and improving the ease of use of the green hydrogen preparation device.
[0029] This utility model provides a green hydrogen production device for a photovoltaic power station. The specific working principle is as follows: When producing green hydrogen in a photovoltaic power station, electrolyte is first injected into the filter box 3 through the injection port 5. Then, impurities are filtered from the electrolyte through the filter frame 4 inside the filter tank 23. Subsequently, the electrolyte flows into the hydrogen production tank 1. Next, the gas separation plate 19 is inserted into the guide groove 24, and the inner side of the groove 26 contacts the isolation plate 20. Then, the elastic force of the return spring 22 pushes the connecting plate 21 to move between the inner walls of the through groove 25, causing the sealing plate 15 to contact the gas separation plate 19, thereby sealing the guide groove 24 and simultaneously sealing the gas separation plate. 19 is fixed. At the same time, the photovoltaic panel 8 converts light energy into electrical energy, which is stored in the battery 2 and then provides power to the anode block 17 and the cathode block 18, so that the anode block 17 and the cathode block 18 react with the electrolyte to produce oxygen and hydrogen respectively. The preparation process is observed through the observation port 6. Then, the oxygen and hydrogen enter the interior of the gas separation box 7 and are separated by the gas separation plate 19. The oxygen is discharged and collected along the oxygen outlet pipe 9, while the hydrogen is compressed by the compressor 11 and discharged along the hydrogen outlet pipe 10 for collection and use. At the same time, the discharge amount of oxygen and hydrogen can be controlled by two control valves 12 to ensure safe discharge.
[0030] When it is necessary to remove the gas separation plate 19, after the oxygen and hydrogen have been completely removed, push the lever 16 to move between the inner walls of the slide groove 14, causing the sliding plate 27 to move between the inner walls of the sealing box 13 and press the return spring 22. Then, the connecting plate 21 moves between the inner walls of the through groove 25 and moves the sealing plate 15 away from the gas separation plate 19, thereby releasing the gas separation plate 19 from its fixation. Then it can be removed, thus completing the use of the green hydrogen preparation device.
[0031] 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.
