Description

Technical Field

[0001] This utility model relates to the technical field of water electrolysis hydrogen production electrolysis units, and in particular to an electrolysis unit for water electrolysis hydrogen production. Background Technology

[0002] The electrolytic cell in the electrolysis unit has a typical filter press structure, in which several electrolysis units are sandwiched in the middle by two heavy end plates, and then the two end plates are pressed together by several long screws, so that the electrolysis unit and the end plates become a whole electrolysis cell. When a problem occurs in an electrolysis unit and it needs to be replaced, all electrolysis units need to be disassembled before replacement, which takes a long time, has high maintenance costs, and delays the user's on-site production.

[0003] In the prior art, CN216378412U discloses a water electrolyzer with individually replaceable electrolysis units. This includes a first fixed end plate and a second fixed end plate, which are connected by parallel connecting shafts and a positioning guide rail. A clamping end plate is detachably mounted on the positioning guide rail and slides within it. The clamping end plate is located between the first and second fixed end plates. Multiple electrolysis units are detachably mounted on the positioning guide rail, each slidingly engaging with it. Each electrolysis unit is located between the first and clamping end plates. A tightening screw assembly is provided on the second fixed end plate. This invention can meet the requirement of individually disassembling electrolysis units; when a problematic electrolysis unit is disassembled, other electrolysis units are not affected.

[0004] This application allows for the individual disassembly of electrolysis units to prevent other electrolysis units from being affected. This involves loosening the tightening screw assembly 7 to loosen the gaps between the individual electrolysis units 6, removing the replacement electrolysis unit 6 from the positioning guide rail 4, hanging the new electrolysis unit 6 on the positioning guide rail 4, and then tightening the tightening screw assembly 7. After loosening the tightening screw assembly, all electrolysis units are in a relaxed state. If they encounter external impacts or vibrations at this time, one or more electrolysis units may slide on the positioning guide rail, causing adjacent electrolysis units to collide and potentially damage them, thus affecting the subsequent working progress of the electrolysis units. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electrolysis unit for hydrogen production by water electrolysis, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An electrolysis unit for hydrogen production by water electrolysis includes a base, with fixed end plates connected to both ends of the top side of the base, a plurality of electrolysis unit bodies arranged between the fixed end plates, a side support plate connected between the corresponding sides of two fixed end plates, and a support member arranged between the side support plate and the electrolysis unit body.

[0008] The support member includes a support groove, a support block, a vertical rod, and a lifting hole. The support groove is opened at the top edge of the side support plate. The support block is fixedly connected to the side of the corresponding electrolysis unit. The support block is inserted into the support groove. The vertical rod is fixedly connected to the top side of the support block. The lifting hole is opened on the side of the vertical rod. The side support plate is also provided with a locking member for locking the support block.

[0009] In a preferred embodiment, the present invention can be further configured such that: the locking member includes a sliding groove, the sliding groove is formed in the side support plate, a sliding rod is slidably connected in the sliding groove, a locking rod is connected to the outer periphery of the sliding rod, the end of the locking rod is inserted into the support block, and an avoidance groove for avoiding the locking rod is also formed in the side support plate.

[0010] In a preferred embodiment, the present invention can be further configured such that the ends of both slide rods extend to the outer side of the side support plate, and the ends of the slide rods are connected to arc-shaped rods, with a pull rod connecting the two arc-shaped rods.

[0011] In a preferred embodiment, the present invention can be further configured such that: a cavity tube is fixedly connected to the side of the fixed end plate near the arc-shaped rod, a spring is connected inside the cavity tube, the end of the spring is connected to the pull rod, and the pull rod is slidably connected to the cavity tube.

[0012] In a preferred embodiment, the present invention can be further configured such that: a positioning ring is rotatably connected to the outer periphery of the pull rod, the positioning ring is fixedly connected to the ends of the two arc-shaped rods, a limiting groove is formed on the outer periphery of the cavity, and a limiting block is connected to the outer periphery of the pull rod, the limiting block being located within the limiting groove.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. The electrolysis unit for hydrogen production by water electrolysis avoids the sliding of the electrolysis unit due to external collisions when the electrolysis unit is removed, thus preventing the collision and damage of two adjacent electrolysis units. At the same time, after the electrolysis unit is placed, there is no need to clamp the electrolysis unit, reducing the pressure on the electrolysis unit itself, reducing its wear and tear during use, and increasing its service life.

[0015] 2. In this electrolysis unit for hydrogen production by water electrolysis, two sliding rods extend to the outside of the side support plate. The ends of the two sliding rods are connected to arc-shaped rods, and a pull rod is connected between the two arc-shaped rods. Dragging the pull rod can move the two arc-shaped rods, thereby causing the two sliding rods to slide. This allows the sliding rods to drive the locking rod to slide away from the support block, so as to release the restriction on the support block and facilitate the separate removal of the individual electrolysis unit.

[0016] 3. In this electrolysis unit for hydrogen production by water electrolysis, a spring is connected inside the cavity tube. When the pull rod is pulled, the spring is stretched. After the electrolysis unit is lifted out separately, when it is necessary to relock the support block, the pull rod is released. The pull rod will move towards the inside of the cavity tube under the action of the spring's recoil force. Ultimately, it can drive the two sliding rods towards the inside of the sliding groove, and drive all the locking rods to insert into the corresponding support blocks, so as to quickly limit the support blocks and the electrolysis unit body.

[0017] 4. In this electrolysis unit for hydrogen production by water electrolysis, after the pull rod is pulled by the spring, the end of the cavity tube is used to limit the limiting block, thereby limiting the pull rod. Then, when the electrolysis unit is taken out, there is no need to continuously pull the pull rod, as the end of the cavity tube limits the pull rod, reducing the fatigue of continuously pulling the pull rod by hand.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1-2 The present invention discloses an electrolysis unit for hydrogen production by water electrolysis, including a base 1, with fixed end plates 2 connected to both ends of the top side of the base 1, a plurality of electrolysis unit bodies 3 arranged between the fixed end plates 2, a side support plate 4 connected between the corresponding sides of the two fixed end plates 2, and a support member 5 arranged between the side support plate 4 and the electrolysis unit body 3.

[0026] The support member 5 includes a support groove 6, a support block 7, a vertical rod 8, and a lifting hole 9. The support groove 6 is opened at the top edge of the side support plate 4. The support block 7 is fixedly connected to the side of the corresponding electrolytic unit 3. The support block 7 is inserted into the support groove 6. The vertical rod 8 is fixedly connected to the top side of the support block 7. The lifting hole 9 is opened on the side of the vertical rod 8. The side support plate 4 is also provided with a locking member 10 for locking the support block 7.

[0027] In this embodiment, reference Figure 1 The electrolytic unit 3 has a support block 7 inserted into the corresponding support groove 6, so that the bottom side wall of the support block 7 fits against the bottom side wall of the support groove 6. This allows the electrolytic unit 3 to be individually contained, preventing it from sliding after being hit by a collision, which could cause adjacent electrolytic units 3 to collide and be damaged. The vertical rod 8 is used to connect with the corresponding support block 7. The side of the vertical rod 8 has a lifting hole 9, which can be used to hang the vertical rod 8 directly when the electrolytic unit 3 is removed, so that the support block 7 and the electrolytic unit 3 can be removed. This achieves the effect of being able to remove the electrolytic unit 3 independently.

[0028] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the locking member 10 includes a sliding groove 11, which is formed in the side support plate 4. A sliding rod 12 is slidably connected in the sliding groove 11. A locking rod 13 is connected to the outer periphery of the sliding rod 12. The end of the locking rod 13 is inserted into the support block 7. The side support plate 4 is also provided with a clearance groove 14 for avoiding the locking rod 13.

[0029] In this embodiment, reference Figure 2The slide groove 11 is located within the side support plate 4. The slide groove 11 within the side support plate 4 is also slidably connected to the slide rod 12. The slide rod 12 slides within the slide groove 11, and a locking rod 13 is connected to the outer periphery of the slide rod 12. The slide rod 12 can drive the locking rod 13 to slide within the clearance groove 14, allowing the locking rod 13 to insert into the corresponding support block 7, thereby further restricting the support block 7 and preventing external collisions and bumps during the use of the electrolysis unit from causing the support block 7 to detach from the support groove 6, which in turn causes the electrolysis unit 3 to detach. As a result, after the electrolysis unit 3 detaches from the side support plate 4, it may fall and be damaged, thus affecting subsequent use.

[0030] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the ends of both slide rods 12 extend to the outside of the side support plate 4, and the ends of the slide rods 12 are connected to arc-shaped rods 15, with a pull rod 16 connecting the two arc-shaped rods 15.

[0031] In this embodiment, reference Figure 2 The pull rod 16 and the two slide rods 12 extend to the outside of the side support plate 4. The ends of the two slide rods 12 are connected to the arc rods 15, and the pull rod 16 is connected between the two arc rods 15. Dragging the pull rod 16 can move the two arc rods 15, thereby causing the two slide rods 12 to slide, so that the slide rods 12 can drive the locking rod 13 to slide away from the support block 7, so as to release the restriction on the support block 7, and thus facilitate the separate lifting out of the individual electrolytic unit 3.

[0032] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a cavity tube 17 is fixedly connected to the side of the fixed end plate 2 near the arc-shaped rod 15. A spring 18 is connected inside the cavity tube 17. The end of the spring 18 is connected to the pull rod 16. The pull rod 16 is slidably connected to the cavity tube 17.

[0033] In this embodiment, reference Figure 2 The cavity 17 contains a spring 18. When the pull rod 16 is pulled, the spring 18 is stretched. After the electrolysis unit is lifted out, when the support block 7 needs to be locked again, the pull rod 16 is released. The pull rod 16 will move towards the inside of the cavity 17 under the action of the spring 18. This will eventually drive the two slide rods 12 towards the inside of the slide groove 11, and drive all the locking rods 13 to insert into the corresponding support block 7, thus achieving the effect of quickly locking the support block 7 and the electrolysis unit 3.

[0034] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3As shown, a positioning ring 19 is rotatably connected to the outer periphery of the pull rod 16. The positioning ring 19 is fixedly connected to the ends of the two arc-shaped rods 15. A limiting groove 20 is formed on the outer periphery of the cavity tube 17. A limiting block 21 is connected to the outer periphery of the pull rod 16. The limiting block 21 is located in the limiting groove 20.

[0035] In this embodiment, reference Figure 1 The cavity 17 has a limiting groove 20 on its outer periphery. A limiting block 21 is connected to the outer periphery of the pull rod 16. When the pull rod 16 is pulled, the limiting block 21 moves until it disengages from the cavity 17. Then, the limiting block 21 is rotated. Because the pull rod 16 is rotatably connected to the positioning ring 19, and the positioning ring 19 is fixedly connected to the arc-shaped rod 15, the rotation of the pull rod 16 avoids affecting the arc-shaped rod 15. After rotating the pull rod 16, the limiting block 21 is brought into contact with the end of the cavity 17. At this point, the pull rod 16 can be released. (Refer to...) Figure 3 When the spring 18 is in place, the pull rod 16 is pulled by the spring 18. The end of the cavity tube 17 limits the limiting block 21, thereby limiting the pull rod 16. Then, when the electrolysis unit is taken out, there is no need to continuously pull the pull rod 16. The limitation by the end of the cavity tube 17 reduces the fatigue of continuously pulling the pull rod 16 by hand.

[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
