Description

Technical Field

[0001] The invention relates to the technical field of water electrolysis hydrogen production, and in particular to a water electrolysis hydrogen production system equipment. Background Art

[0002] As the most promising clean energy, hydrogen energy has the advantages of no pollution and high calorific value. At the same time, hydrogen energy can be synergistically exchanged with wind power and photovoltaics to consume renewable energy. In recent years, it has attracted more and more attention. Water electrolysis to produce hydrogen is a relatively convenient method. Direct current is passed through an electrolytic cell filled with potassium hydroxide or sodium hydroxide. Water molecules undergo electrochemical reactions on the electrodes and decompose into hydrogen and oxygen. When direct current is passed through some electrolyte aqueous solutions, the decomposed substances have nothing to do with the original electrolyte. What is decomposed is water as a solvent, and the original electrolyte remains in the water.

[0003] The Chinese patent proposes a water electrolysis hydrogen production device, the publication number is CN117187845A, comprising: an electrolytic box, a mounting groove is provided in the middle of the upper side of the electrolytic box, and a mounting port is provided in the middle of the lower side of the mounting groove; an electrode assembly, the electrode assembly is installed in the middle of the electrolytic box, the electrode assembly includes a cover plate, the cover plate is installed in the mounting groove by bolts, a mounting frame is fixed to the middle of the lower side of the cover plate, a sealing block is fixed to the side of the mounting frame close to the limiting groove, an anode electrode plate is installed on the left side of the mounting frame, a cathode electrode plate is installed on the right side of the mounting frame, and a diaphragm is installed in the middle of the mounting frame.

[0004] The above-mentioned device is provided with an electrode assembly, and the installation between the electrode assembly and the electrolytic box is simple, which facilitates the repair or replacement of the anode electrode plate and the cathode electrode plate on the electrode assembly. However, the bolt connection between the electrode assembly and the electrolytic box requires the removal of multiple bolts one by one when the electrode assembly is dismantled, which is cumbersome and inefficient. Moreover, after the electrode assembly is dismantled, the anode electrode plate or the cathode electrode plate cannot be repaired or replaced separately, resulting in difficult maintenance operations and excessive costs.

[0005] Therefore, the design is highly practical and when the electrode assembly is installed, the frame can automatically install and fix the anode electrode plate and the cathode electrode plate, which greatly improves the convenience of installation of the electrode assembly. After the electrode assembly is removed, the frame can automatically release the anode electrode plate and the cathode electrode plate, so that when the anode electrode plate or the cathode electrode plate needs to be repaired or replaced separately, there is no need for secondary disassembly, which effectively reduces the workload and maintenance costs. It is very necessary to have an electrolysis water hydrogen production system equipment. Summary of the invention

The first sealed airbag is in close contact with the first installation block to produce deformation and tightly hold the recessed portion of the first installation block. When the moving plate moves downward, the wedge block moves downward to insert into the insertion port and squeeze the wedge-shaped slider. The wedge-shaped slider is squeezed to make the clamping rod move out of the active cavity and engage with the clamping hole on the insertion block. The pressing block is pressed down until the positioning rod is embedded in the fixing groove. The wedge-shaped clamping block in the fixing groove can automatically engage with the clamping groove on the positioning rod, thereby realizing the locking and fixing of the sliding rod, completing the rapid installation of the electrode assembly, and improving the working efficiency of the equipment while having good fixity and sealing.

[0020] 2. In the present invention, by pulling the pull ring, the second guide rod drives the wedge-shaped clamping block to release the clamping connection with the positioning rod and retract it into the cavity, the third spring rebounds to reset the pressing block and the pressure plate, the first spring rebounds to reset the movable plate and the wedge-shaped block, and the gas in the first sealing airbag can be drawn back into the air cylinder when the piston is reset, the second spring rebounds to reset the wedge-shaped slider, so that the clamping rod is released from the clamping block and retracts into the movable cavity, and then the frame is pulled up and out of the first installation frame through the first handle, so that the electrode assembly can be quickly disassembled, the operation is simple and convenient, and the maintenance efficiency of the electrode assembly is improved.

[0021] 3. In the present invention, when installing the electrode assembly, the pressing block is pressed downward to drive the connecting block to move downward, so that the third guide rod drives the sealing plate to press the gas in the gas storage box into the second sealing airbag through the connecting hose, so that the second sealing airbag expands and deforms and fastens and fixes the second installation block, thereby realizing automatic installation and fixation of the anode electrode plate and the cathode electrode plate. At the same time, through the arrangement of the first sealing airbag and the second sealing airbag, the installation sealing of the frame and the anode electrode plate or the cathode electrode plate can be effectively improved.

[0022] 4. In the present invention, when the frame is dismantled, the sliding rod drives the installation sleeve to reset, so that the connecting block drives the sealing plate to move upward along the air storage box through the third guide rod. At this time, the gas in the two second sealing airbags used to fix the anode electrode plate and the cathode electrode plate is sucked back into the two air storage boxes through the connecting hose, and the second sealing airbags shrink and release the fixation of the second installation block. After that, the anode electrode plate or cathode electrode plate that needs maintenance and replacement can be individually pulled out from the installation socket through the second handle.
