Description

Technical Field

[0001] The invention relates to the technical field of alkaline water hydrogen production electrolyzers, and in particular to ground turning equipment for alkaline water hydrogen production electrolyzers. Background Art

[0002] An alkaline water hydrogen electrolyzer is an electrochemical device used to produce hydrogen and oxygen by electrolyzing water. This electrolyzer uses an alkaline electrolyte (such as sodium hydroxide or potassium hydroxide solution) and is usually operated under high pH conditions to ensure that the hydrogen generated during the electrolysis process is dominant, while the amount of oxygen generated is small. In alkaline water electrolyzers, alkaline electrolytes such as sodium hydroxide (NaOH) or potassium hydroxide (KOH) solutions are usually used. These solutions provide the required ionic conductivity while ensuring that too much oxygen does not appear during the electrolysis process to hinder hydrogen production.

[0003] Alkaline water hydrogen production electrolyzers are mostly installed vertically, but used horizontally. Therefore, after the manual assembly of the large-scale alkaline water hydrogen production electrolyzer is completed, it needs to be turned over and dumped. The traditional large-scale alkaline water hydrogen production electrolyzer is turned over manually with multiple cranes, which is very inconvenient to operate. If the operation is improper, the alkaline water hydrogen production electrolyzer will fall from the air when turning over, which will not only damage the product, but also cause harm to the operator. Therefore, it is extremely unsafe to use this method to turn over the alkaline water hydrogen production electrolyzer. Summary of the invention

[0004] In order to solve the problems of low efficiency and great safety hazards in the prior art of manual turning with a crane, the present invention provides a ground turning device for an alkaline water hydrogen production electrolyzer, which can rotate 0° and 90°.

[0036] Step 2: Control the external device through the PLC controller 21 to push the movable frame 14 to move along the outer surface of the fixed guide rail 13, adjust the placement position of the connecting seat 15 on the outer surface of the electrolytic cell, start the limit oil cylinder 16 to push the positioning pin 17 to move, so that one end of the positioning pin 17 is movably abutted against the outer surface of the electrolytic cell, and then the positioning pin 17 is limited and fixed to the four corners of the electrolytic cell, so as to keep the electrolytic cell in a fixed placement state on the upper surface of the L-shaped large bracket 3;

[0037] Step 3, the hydraulic cylinder 5 is controlled to start again through the PLC controller 21, so that the hydraulic cylinder 5 pushes the L-shaped large bracket 3 to rotate along the inside of the fixed bracket 2, thereby driving the electrolytic cell on the upper surface of the L-shaped large bracket 3 to turn over, so that the L-shaped large bracket 3 is turned over 90 degrees to adjust the electrolytic cell to a vertical position, and the support frame 6 is turned over to a horizontal state, so that the bottom end of the electrolytic cell is placed on the upper surface of the multiple support sleeves 8;

[0038] Step 4: Make the multiple buffer blocks 19 support the electrolytic cell movably and move downward along the inside of the placement slot 18, thereby pushing the spring 20 to compress, so that the buffer blocks 19 cooperate with the spring 20 to buffer and support the electrolytic cell, and keep the electrolytic cell in a stable placement state on the outer surface of the support sleeve 8;

[0039] Step five, protect the operators around the L-shaped large bracket 3 through the protective fence 22 and the fence door 23, and keep people moving outside a certain safe range on the outer surface of the L-shaped large bracket 3.
