Description

Technical Field

[0001] This application relates to the field of hydrogen production equipment technology, specifically to an alkaline hydrogen production electrolyzer. Background Technology

[0002] Alkaline electrolyzers are one of the most mature and widely used technologies for producing hydrogen from water electrolysis. They use a liquid alkaline electrolyte (usually potassium hydroxide solution) to decompose water, producing hydrogen and oxygen. An electrolyzer typically includes at least an end plate, electrolysis units, and a screw assembly. In existing electrolyzers, the internal units of the electrolysis cells are embedded within each other. Over time, corrosion or wear of the electrodes can lead to voltage instability in the smaller electrolysis chamber, resulting in a voltage difference that deviates from the design voltage and thus affecting gas production.

[0003] Patent application number 2024116440062 discloses an alkaline electrolyzer for water electrolysis to produce hydrogen, which allows for synchronous energization of exposed copper strips via metal electrical contacts on the electrolysis unit. However, it still has the following problems:

[0004] 1. Uneven clamping force: The electrolytic cell achieves a tight contact between the metal electrical contact sheet and the copper strip through a flexible pressure plate. However, due to the large span of the flexible pressure plate, it is easy for the two sides of the flexible pressure plate to achieve good compression of the metal electrical contact sheet, while the middle cannot provide sufficient pressure. Even though the flexible pressure plate has been pre-treated with "upward curve at both ends", insufficient clamping force will still occur after long-term use.

[0005] 2. The operation is cumbersome, requiring each component such as the pallet strip, copper strip, flexible pressure strip, and metal electrical contact piece to be operated individually. Summary of the Invention

[0074] S1, Through-rod assembly 93:

[0075] The threaded rod 931 is passed through the drive through hole 914 and the drive plug 41 and guide cylinder 142 of the power assembly 8, so that both ends of the threaded rod 931 are exposed on the outside of the end plate 91.

[0076] Tighten the fastening bolts 933 at both ends to compress the corresponding disc spring assembly 932, thereby driving the drive assembly 4 to slide inward;

[0077] S2, Extrusion component 3 extrusion action:

[0078] The drive cylinder 41, drive inclined surface 42, and guide ring groove 43 move inward against the damping of the outer cylinder compression spring 143;

[0079] The driving inclined surface 42 acts on the corresponding driven inclined surface 33, thereby driving the pressing assembly 3 to move downward against the damping of the longitudinal compression spring 35, and pressing the wiring baffle 921 firmly onto the wiring main board 21.

[0080] The alkaline hydrogen production electrolyzer described in this case can also synchronously adjust the downward damping of the extrusion assembly 3:

[0081] The drive rack 62 is pushed, and the drive rack 62 moves and acts on the outer ring gear 512, driving the adjusting outer ring 51 to rotate;

[0082] The inner ring gear 513 rotates and drives the small diameter gear 521 and the external threaded tube 522 to rotate.
