Description

Technical Field

[0001] This utility model relates to the field of hydrogen production technology through water electrolysis, and in particular to a gradient composite coating nickel mesh structure for hydrogen production through water electrolysis. Background Technology

[0002] Hydrogen production via water electrolysis is a technology that uses electricity to decompose water into hydrogen and oxygen. Based on the principle of electrolysis, hydrogen production via water electrolysis is mainly divided into alkaline water electrolysis, proton exchange membrane water electrolysis, and solid oxide water electrolysis, depending on the electrolyte used. The only raw material in the hydrogen production process is water, and the only products are hydrogen and oxygen. It does not produce greenhouse gases or other pollutants, making it a green hydrogen production method. Water is one of the most abundant resources on Earth, with wide and sustainable sources, providing a sufficient raw material guarantee for large-scale hydrogen production. The scale of hydrogen production can be flexibly adjusted according to the power supply situation, and it can well adapt to the intermittent characteristics of renewable energy power generation, realizing the storage and conversion of electrical energy. In order to better produce hydrogen, a gradient composite coating sprayed nickel mesh structure for hydrogen production via water electrolysis is required.

[0003] Currently available gradient composite coating nickel mesh structures for hydrogen production via water electrolysis mainly consist of a nickel mesh substrate and a gradient composite coating. During use, nickel itself has good conductivity, and the nickel mesh, as the basic electrode structure, provides a good electron transport channel for the electrochemical reaction during water electrolysis, allowing electrons to be smoothly conducted between the electrode and the external circuit, ensuring the smooth progress of the electrolysis reaction. However, the coating and the nickel mesh substrate are not firmly bonded, leading to decreased electrode performance and shortened service life. To address these issues, existing technologies only perform sandblasting pretreatment on the nickel mesh before coating to achieve a suitable surface roughness, increase the contact area and mechanical interlocking between the coating and the substrate, and improve adhesion. However, no protection is provided for the nickel mesh structure, making it prone to deformation, wrinkles, or even damage. This results in a reduction in surface area and active sites, thereby reducing the efficiency of the hydrogen evolution reaction and potentially affecting the conductivity of the electrode, further impacting the effectiveness of hydrogen production via water electrolysis. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a gradient composite coating nickel mesh structure for hydrogen production by water electrolysis. It aims to improve the problem that the nickel mesh structure is not protected in the prior art, which is prone to deformation, wrinkling or even damage, resulting in a reduction in surface area and active sites, thereby reducing the efficiency of hydrogen evolution reaction. It may also affect the conductivity of the electrode, further affecting the effect of hydrogen production by water electrolysis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gradient composite coating nickel mesh structure for hydrogen production by water electrolysis, comprising a base plate, a nickel mesh plate fixedly connected to the inner top of the base plate, a top plate fixedly connected to the top of the nickel mesh plate, connecting pressing blocks slidably connected to the left and right sides of the top plate, two connecting blocks I fixedly connected to the front and rear bottom sides of the pressing blocks, a pushing strip rotatably connected to the bottom of the connecting blocks I, a connecting block II rotatably connected to the bottom of the pushing strip, a hook fixedly connected to the bottom of the connecting blocks II, a limiting crossbar slidably connected to the middle of the hook, a spring fixedly connected to the middle of the outer wall of the limiting crossbar, and a support mechanism provided on the front and rear sides of the top plate, the support mechanism being used to fix the supporting shell.

[0006] As a further description of the above technical solution:

[0007] The support mechanism includes a handle, a rotating shaft rotatably connected to the left side of the handle, a rotating block rotatably connected to the middle of the outer wall of the rotating shaft, a rotating column fixedly connected to the bottom of the rotating block, a locking strip fixedly connected to the middle of the rotating column, a rotating bar rotatably connected to the bottom of the outer wall of the rotating column, a locking groove opened on the right side of the inside of the rotating bar, and a second rotating groove opened on the top right side of the inside of the rotating bar.

[0008] As a further description of the above technical solution:

[0009] The bottom plate has two locking slots on its top left and right sides, and the top plate has two sliding slots on its top left and right sides.

[0010] As a further description of the above technical solution:

[0011] A movable handle is fixedly connected to both the left and right sides of the top plate, and an anti-slip sleeve is fixedly connected to the middle of the outer wall of the movable handle.

[0012] As a further description of the above technical solution:

[0013] The top of the pressing block is fixedly connected to an anti-slip block.

[0014] As a further description of the above technical solution:

[0015] Sealing gaskets are fixedly connected to the top four sides of the base plate.

[0016] As a further description of the above technical solution:

[0017] Two rotating grooves are provided on the front and rear sides of the top plate.

[0018] As a further description of the above technical solution:

[0019] An anti-slip pad is fixedly connected to the bottom of the outer wall of the hook.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, in order to protect the nickel mesh, it is placed between the bottom plate and the top plate. The pressing block drives the connecting block one to move downward, which in turn pushes the push bar to rotate, causing the connecting block two to move downward. The movement of the connecting block two causes the hook to slide on the outer wall of the limiting crossbar, squeezing the spring. The elasticity of the spring causes the limiting crossbar to engage in the locking groove, thereby achieving the protection and fixation of the nickel mesh and extending its service life.

[0022] 2. In this utility model, in order to fix the supporting shell, the rotating handle needs to be rotated to vertical on the outer wall of the rotating shaft and pulled so that the locking strip is engaged in the locking groove of the rotating strip. Rotating the rotating handle causes the rotating block to rotate, which in turn drives the rotating column and the rotating strip to rotate, thereby fixing the supporting shell and preventing movement from affecting efficiency.

[0039] Working principle: In order to protect and fix the nickel mesh plate 3, the nickel mesh plate 3 is placed between the bottom plate 1 and the top plate 4. Pressing the pressing block 5 causes the connecting block 6 to move downward. The movement of the connecting block 6 causes the push bar 7 to rotate. The rotation of the push bar 7 causes the connecting block 8 to move downward. The movement of the connecting block 8 causes the hook 9 to slide on the outer wall of the limiting crossbar 10 and squeeze the spring 11. Under the elastic action of the spring 11, the limiting crossbar 10 is driven to engage inside the locking groove 12, thereby protecting and fixing the nickel mesh plate 3 and improving the service life of the nickel mesh plate 3.

[0040] To fix the supporting shell, the handle 201 is rotated vertically on the outer wall of the rotating shaft 202 and pulled upwards, causing the locking strip 205 to engage inside the slot 208 opened on the rotating bar 206. Rotating the handle 201 causes the rotating block 203 to rotate, which in turn causes the rotating column 204 to rotate, and the rotating column 204 to rotate, thus fixing the supporting shell and preventing movement from affecting work efficiency.
