Description

Technical Field

[0001] This utility model relates to the field of nickel mesh technology, specifically a novel nickel mesh. Background Technology

[0002] Nickel mesh is a key electrode material in hydrogen electrolyzers, offering stable conductivity and an increased pore structure that accelerates reaction rates. High-purity nickel mesh coated with catalysts or sprayed with Raney nickel can further enhance performance. The application of nickel mesh will improve hydrogen production efficiency, reduce costs, and promote the development of the hydrogen energy industry. Nickel mesh plays a crucial role in hydrogen electrolyzers. As an excellent electrode material, nickel mesh not only possesses good conductivity and stability, capable of withstanding high current densities, but its unique pore structure also significantly increases the electrode surface area, thereby improving the electrolysis reaction rate. In hydrogen production processes, nickel mesh is commonly used as an anode or cathode material.

[0003] Currently, the common method for fixing the electrode plate and nickel mesh is welding. However, this makes it difficult to separate the electrode plate and nickel mesh when the nickel mesh is damaged and needs replacement. Both the electrode plate and the nickel mesh must be replaced together, which is wasteful and cumbersome. Therefore, technological innovation and design optimization are needed to achieve an optimized new type of nickel mesh. Utility Model Content

[0004] Currently, the common method for fixing the electrode plate and nickel mesh is welding. However, this makes it difficult to separate the electrode plate and nickel mesh when the nickel mesh is damaged and needs replacement, requiring them to be replaced together, which is wasteful and cumbersome. To solve these problems, this application provides a novel nickel mesh. By aligning the limiting block on the fixing ring with the limiting groove on the electrode plate and inserting it, followed by rotation, the fixing ring and electrode plate can be vertically limited. A spring is compressed, and under its action, the spring drives the insert pin through the baffle into the slot, thereby quickly limiting the fixing ring and electrode plate horizontally, increasing installation efficiency and facilitating disassembly.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A novel nickel mesh, comprising:

[0007] An electrode plate, wherein a fixing ring is provided at the top of the electrode plate, and a nickel mesh body is fixed on the fixing ring;

[0008] A plug-in mechanism, located between the electrode plate and the retaining ring, is used to connect the electrode plate and the retaining ring;

[0009] A limiting mechanism is located on a fixed ring and is used to limit the position of the electrode plate and the fixed ring.

[0010] In one possible implementation, the insertion mechanism includes a plurality of limiting grooves formed in a circular matrix on the side of the electrode plate facing the fixed ring, a limiting block fixed on the side of the fixed ring facing the electrode plate, the limiting block being inserted into the limiting groove and moving horizontally, the limiting block being aligned with the limiting groove and inserted, and then rotated.

[0011] In one possible implementation, the limiting block is L-shaped and the limiting groove is also L-shaped, which facilitates the limiting of the fixing ring and the electrode plate.

[0012] In one possible implementation, the limiting mechanism includes a cylinder fixed to the top of a fixing ring, a cylindrical groove at the bottom of the cylinder, an insert through the cylinder, the bottom end of the insert through the fixing ring, a slot on the electrode plate, the insert and the slot matching each other, the insert sliding on the cylinder and the fixing ring, and when the insert is inserted into the slot, it limits the fixing ring and the electrode plate in the horizontal direction.

[0013] In one possible implementation, a spring is sleeved inside the cylindrical groove outside the insert post, and a baffle is fixed on the insert post at the bottom of the spring. The spring is in a compressed state, and under the action of the spring, the spring will drive the insert post to be inserted into the slot through the baffle.

[0014] In one possible implementation, a rectangular slot is formed at the top of the cylinder, and a rectangular block is fixed on the insert. The rectangular block matches the rectangular slot. When the insert moves out of the slot, the rectangular block moves with the insert through the rectangular slot and to the top of the cylinder. Pulling the insert upward causes it to move out of the slot. At this time, the rectangular block moves to the top of the rectangular slot. Rotating the insert causes the rectangular block to rotate, so that the rectangular block is no longer aligned with the rectangular slot. When the insert is released, it is limited by the obstruction of the rectangular block. This eliminates the need to continuously pull the insert to prevent it from inserting into the slot, making it more convenient.

[0015] In one possible implementation, a pull plate is fixed to the top of the insertion post, and the outer side of the pull plate is provided with anti-slip texture to facilitate pulling the insertion post by pulling the pull plate.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. By aligning the limiting block on the fixed ring with the limiting groove on the electrode plate and inserting it, and then rotating it, the fixed ring and the electrode plate can be vertically limited.

[0018] 2. When the spring is in a compressed state, it will drive the insert pin into the slot through the baffle, thereby quickly limiting the horizontal movement of the fixing ring and the electrode plate, increasing installation efficiency and facilitating disassembly and assembly.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This embodiment describes the specific structure of a novel nickel mesh, as detailed in the following reference. Figures 1-5 As shown, a novel nickel mesh includes:

[0027] Electrode 3, with a fixing ring 2 on the top of electrode 3, and a nickel mesh body 4 fixed on the fixing ring 2;

[0028] The insertion mechanism is located between the electrode plate 3 and the fixing ring 2, and is used to connect the electrode plate 3 and the fixing ring 2.

[0029] The limiting mechanism is located on the fixed ring 2 and is used to limit the electrode plate 3 and the fixed ring 2.

[0030] Currently, the common method for fixing the electrode plate 3 and the nickel mesh is welding. However, this makes it difficult to separate the electrode plate 3 and the nickel mesh when the nickel mesh is damaged and needs to be replaced. The electrode plate 3 and the nickel mesh need to be replaced together, which is wasteful and troublesome.

[0031] Therefore, the insertion mechanism includes a plurality of limiting grooves 5 formed in a circular matrix on the side of the electrode plate 3 facing the fixed ring 2, and a limiting block 7 fixed on the side of the fixed ring 2 facing the electrode plate 3. The limiting block 7 can be inserted into the limiting groove 5 and moved horizontally. The limiting block 7 is aligned with the limiting groove 5 and inserted, and then rotated.

[0032] In addition, the limiting block 7 is L-shaped and the limiting groove 5 is also L-shaped, which facilitates the limiting of the fixing ring 2 and the electrode plate 3.

[0033] More specifically, the limiting mechanism includes a cylinder 1 fixed to the top of the fixing ring 2, a cylindrical groove 10 at the bottom of the cylinder 1, an insert 8 passing through the cylinder 1, and the bottom end of the insert 8 passing through the fixing ring 2. A slot 6 is provided on the electrode plate 3. The insert 8 and the slot 6 are matched, and the insert 8 can slide on the cylinder 1 and the fixing ring 2. When the insert 8 is inserted into the slot 6, it limits the fixing ring 2 and the electrode plate 3 horizontally. A spring is sleeved inside the cylindrical groove 10 outside the insert 8, and a baffle 11 is fixed to the bottom of the spring on the insert 8. The spring is in a compressed state, and under the action of the spring, the spring will drive the insert 8 into the slot 6 through the baffle 11. The cylinder 1 has a rectangular slot 12 at its top. A rectangular block 9 is fixed on the insert post 8. The rectangular block 9 matches the rectangular slot 12. When the insert post 8 moves out of the slot 6, the rectangular block 9 moves with the insert post 8 through the rectangular slot 12 and to the top of the cylinder 1. Pulling the insert post 8 upwards causes it to move out of the slot 6. At this time, the rectangular block 9 moves to the top of the rectangular slot 12. Rotating the insert post 8 causes the rectangular block 9 to rotate, so that the rectangular block 9 is no longer aligned with the rectangular slot 12. At this time, the insert post 8 is released. Under the obstruction of the rectangular block 9, the insert post 8 will be limited. It is more convenient that the insert post 8 does not need to be pulled by hand to prevent it from being inserted into the slot 6.

[0034] It is worth noting that a pull plate 13 is fixed at the top of the insertion post 8, and the outer side of the pull plate 13 is provided with anti-slip texture, so that the insertion post 8 can be pulled by the pull plate 13.

[0035] When the operator needs to install the electrode plate 3 and the nickel mesh, first pull the insert post 8 upwards to move it out of the slot 6. At this time, the rectangular block 9 moves to the top of the rectangular groove 12. Rotate the insert post 8, which drives the rectangular block 9 to rotate, so that the rectangular block 9 is no longer aligned with the rectangular groove 12. Then release the insert post 8. Under the obstruction of the rectangular block 9, the insert post 8 will be limited, eliminating the need to continuously pull the insert post 8 to prevent it from being inserted into the slot 6, which is more convenient. Then align the limiting block 7 on the fixing ring 2 with the limiting groove 5 on the electrode plate 3 and insert it. Then rotate it, and the insert post 8 will be aligned with the slot 6. Rotate the insert post 8 so that the rectangular block 9 is aligned with the rectangular groove 12. Under the action of the spring, the spring will drive the insert post 8 to be inserted into the slot 6 through the baffle 11, thereby limiting the electrode plate 3 and the fixing ring 2. To separate the electrode plate 3 and the fixing ring 2, simply reverse the operation.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
