Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of water electrolysis for hydrogen production technology, and more specifically, to an alkaline hydrogen production water electrolysis apparatus. Background Technology
[0002] Alkaline hydrogen production, as a mature and widely used hydrogen production technology, occupies an important position in the hydrogen energy industry. Water electrolysis devices are used in alkaline hydrogen production. The water electrolyzer is the core equipment of the device, producing hydrogen through the electrolysis of water. The electrolyzer consists of a tank, an anode, and a cathode. Most electrolyzers use a diaphragm to separate the anode and cathode chambers. Based on the electrolyte, they are classified into three types: aqueous solution electrolyzers, molten salt electrolyzers, and non-aqueous solution electrolyzers. When direct current passes through the electrolyzer, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface to produce the desired product. In existing water electrolysis devices, the electrode materials in the water electrolysis cell are prone to corrosion and degradation during long-term electrolysis. Therefore, it is necessary to frequently disassemble the water electrolysis cell to replace the internal electrode materials. However, current water electrolysis cell assembly usually uses screws and nuts for fastening or metal straps for clamping. Both of these methods require applying fastening force at multiple points around the end plate, which results in a lot of time required to disassemble the water electrolysis cell, making it difficult to achieve rapid disassembly and increasing the time required to replace the internal electrode materials.

The locking block is mounted on the inner side of the transmission plate and moves synchronously with the transmission plate. The second return spring is sleeved on the adjusting rod, and its two ends are respectively connected to the locking seat and the transmission plate.
[0008] As a preferred embodiment of the alkaline hydrogen production water electrolysis device of this utility model, in order to achieve sliding limit of the transmission plate and ensure the stability of the transmission plate during sliding, limit slide rails are installed on both sides of the inner wall of the locking seat, and the transmission plate is slidably connected to the limit slide rails.
[0009] In a preferred embodiment of the alkaline hydrogen production water electrolysis device of this utility model, in order to block and limit the transmission plate on the limiting slide rail and prevent the transmission plate from derailing, a limiting baffle is installed on the inner side of the limiting slide rail, and the outer side of the limiting baffle is connected to the inner wall of the locking seat.
[0010] In a preferred embodiment of the alkaline hydrogen production water electrolysis device of this utility model, in order to achieve the snap-fit fixation between the snap-fit block and the snap-fit plate, snap-fit grooves are provided on both sides of the outer side of the snap-fit plate, and the width of the snap-fit grooves is adapted to the width of the snap-fit block.

[0016] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0017] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0018] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0022] like Figures 1-6As shown, this embodiment illustrates an alkaline hydrogen production water electrolysis device, including an electrolysis cell body 1, with a first assembly plate 2 and a second assembly plate 3 respectively disposed on both sides of the electrolysis cell body 1. It also includes a connecting column 4, a connecting sleeve 5, a cylinder 6, a guide column 7, a plug-in seat 8, an adjusting mechanism, a transmission component 9, a locking seat 10, a locking plate 11, a pushing assembly, and a locking mechanism. Compared to the technical problems of existing water electrolysis devices where the water electrolysis cell is difficult to disassemble quickly and requires a long time to replace the internal electrode materials, this embodiment, through the cooperation of the adjusting mechanism, the transmission component 9, the locking plate 11, and the pushing assembly, achieves the adjustment of the plug-in seat 8 on the guide column 7. The adjustment of the upper position allows for adjustment of the insertion state of the plug-in seat 8 into the connecting post 4 and the connecting sleeve 5. After the force applied by the pushing component to the adjustment mechanism disappears, the adjustment component can drive the plug-in seat 8 to automatically return to its original position through the transmission component 9. This enables the rapid assembly and disassembly of the water electrolysis cell, saving the time required for assembly and disassembly and improving work efficiency. Through the cooperation of the snap-fit seat 10, snap-fit plate 11 and snap-fit mechanism, the snap-fit positioning of the pushing component is achieved, ensuring the stability of the pushing component after it is inserted into the connecting post 4. This, in turn, ensures the stability of the plug-in seat 8 after it is inserted into the connecting post 4 and the connecting sleeve 5, thereby ensuring the assembly strength of the water electrolysis cell. like Figure 1 and Figure 2 As shown, multiple connecting posts 4 are installed on one side of the first assembly plate 2, and multiple connecting sleeves 5 are installed on one side of the second assembly plate 3, as shown. Figure 3 and Figure 4 As shown, the cylinder 6 is installed in the middle of the inner wall of the connecting column 4. Multiple guide columns 7 are installed on the outer side of the cylinder 6, and insertion seats 8 are sleeved on the guide columns 7. Multiple slots are provided on the outer side of the connecting column 4 and the inner wall of the connecting sleeve 5. The inner diameter of the slots matches the outer diameter of the insertion end of the insertion seat 8. The insertion seat 8 can be inserted into the interior of the connecting column 4 and the connecting sleeve 5 through the slots, thereby achieving the insertion and fixation of the connecting column 4 and the connecting sleeve 5. The adjustment mechanism is located inside the cylinder 6 and is connected to the insertion seat 8 via a transmission component 9. The transmission component 9 consists of a connecting plate and two hinge seats. The connecting plate is sleeved on the two hinge seats. The adjustment mechanism includes a transmission seat 101, a moving disk 102, and a first return spring 103. like Figure 1 and Figure 6As shown, the snap-fit seat 10 is installed on one of the two sides of the second assembly plate 3. A snap-fit plate 11 is inserted into the snap-fit seat 10. Multiple sets of pushing components are installed on the outer side of the snap-fit plate 11. The pushing components include a connecting rod 301, a positioning sleeve 302, and a push rod 303. Two sets of snap-fit mechanisms are provided inside the snap-fit seat 10. The snap-fit mechanism includes an adjusting rod 201, a transmission plate 202, a snap-fit block 203, and a second return spring 204. Limiting slide rails are installed on both sides of the inner wall of the snap-fit seat 10. The transmission plate 202 is slidably connected to the limiting slide rail. The limiting slide rail can slide and limit the transmission plate 202, thereby ensuring the stability of the transmission plate 202 when sliding. A limiting baffle is installed on the inner side of the limiting slide rail. The outer side of the limiting baffle is connected to the inner wall of the snap-fit seat 10. The limiting baffle can... The position of the transmission plate 202 on the limiting slide rail is blocked and limited, thereby preventing the transmission plate 202 from derailing. The outer sides of the snap-fit plate 11 are provided with snap-fit grooves, the width of which is adapted to the width of the snap-fit block 203. The snap-fit block 203 can snap-fit with the snap-fit plate 11 through the snap-fit groove, thereby realizing the snap-fit positioning of the snap-fit plate 11 inside the snap-fit seat 10. The cooperation of the adjustment mechanism, transmission component 9, snap-fit plate 11 and push assembly can realize the adjustment of the position of the plug seat 8 on the guide post 7, and can realize the quick assembly and disassembly of the water electrolysis cell, saving the time required for the assembly and disassembly of the water electrolysis cell. The cooperation of the snap-fit seat 10, snap-fit plate 11 and snap-fit mechanism can realize the snap-fit positioning of the push assembly, thereby ensuring the firmness of the water electrolysis cell after assembly.
[0023] Working principle: When the entire electrolysis tank needs to be disassembled, the worker pulls the adjusting rod 201 outward. The adjusting rod 201 drives the transmission plate 202 to slide outward along the limit slide rail. The transmission plate 202 drives the locking block 203 to move outward, canceling the locking block 203's engagement with the locking plate 11. After cancellation, the worker pulls the locking plate 11 out of the locking seat 10. The locking plate 11 drives the pushing assembly to be removed from the connecting column 4, canceling the pushing force applied by the pushing assembly to the moving disk 102. After the pushing force disappears, the transmission seat 10... 01 After being stretched, the first return spring 103 drives the cylinder 6 to move towards the moving plate 102 inside the cylinder 6. The transmission seat 101 drives the moving plate 102 to move. The moving plate 102 drives the plug seat 8 to move inward along the guide post 7 through the transmission component 9, thus canceling the plug seat 8's plug-in fixing of the connecting post 4 and the connecting sleeve 5. After cancellation, the operator pulls the connecting post 4 out from inside the second assembly plate 3, thereby realizing the overall disassembly of the water electrolysis cell. After disassembly, the operator replaces the electrode material inside the water electrolysis cell.
