Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a conductive rod for an electrolytic electrode plate with long-lasting and stable corrosion resistance and conductivity. Background Technology

[0002] A conductive rod is a metal rod-shaped component used to conduct electric current. Conductive rods are typically long and slender, with their length varying depending on the specific application. They generally possess good straightness to ensure efficient connection of different electrical devices or components during installation and use. Copper is one of the most commonly used materials for making conductive rods. This is because copper has excellent electrical conductivity, second only to silver, and its cost is relatively low, while also offering good machinability. It can be easily manufactured into conductive rods of various shapes.

[0003] Currently, existing conductive rods are generally composed of a copper rod and a stainless steel sheath. However, due to the long-term effects of corrosive substances such as moisture and salt in the external environment, the surface of the conductive rod and the joint with the stainless steel sheath are susceptible to corrosion. This can easily lead to a decrease in the mechanical strength of the conductive rod, potentially causing breakage, affecting conductivity, reducing conductivity efficiency, and limiting the service life of the conductive rod. Therefore, it is necessary to propose a corrosion-resistant conductive rod for electrolytic plates with long-lasting and stable conductivity to solve the above problems. Utility Model Content

It aims to improve upon existing conductive rods, which are generally composed of a copper rod and a stainless steel sheath. However, due to the long-term effects of corrosive substances such as moisture and salt in the external environment, the surface of the conductive rod and the joint with the stainless steel sheath are easily corroded. This can lead to a decrease in the mechanical strength of the conductive rod, potentially causing breakage, affecting the conductive effect, reducing conductivity, and limiting the service life of the conductive rod.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example

[0022] Please see Figures 1-4 This utility model provides a technical solution: a conductive rod for an electrolytic electrode plate with corrosion resistance and stable conductivity, comprising a conductive rod 100 and a stainless steel coating layer 200 wrapped around the conductive rod 100, and a composite protective structure 300 located between the conductive rod 100 and the stainless steel coating layer 200.

[0023] Please see Figures 1-4 The composite protective structure 300 includes a protective layer group 310, a corrosion-resistant sealing layer 320, and a reinforcing layer 330. The protective layer group 310 is coated on the surface of the conductive rod 100, the corrosion-resistant sealing layer 320 is wrapped around the surface of the conductive rod 100, the corrosion-resistant sealing layer 320 is located outside the protective layer group 310, the stainless steel wrapping layer 200 is interference-wrapped around the surface of the corrosion-resistant sealing layer 320, and the reinforcing layer 330 is located inside the corrosion-resistant sealing layer 320.

[0024] The conductive rod 100 is hollow inside, and its surface is uniformly formed with arc-shaped grooves 110. This hollow design reduces weight, while thicker walls at critical stress points enhance load-bearing capacity. The inner surface of the corrosion-resistant sealing layer 320 has arc-shaped protrusions 321 that match the arc-shaped grooves 110. These protrusions 321 engage with the interior of the arc-shaped grooves 110. The corrosion-resistant sealing layer 320 can be made of silicone rubber to increase resistance to strong acids and alkalis. Furthermore, the arc-shaped protrusions 321 and the arc-shaped grooves 110 increase the contact area between the corrosion-resistant sealing layer 320 and the conductive rod 100, resulting in a tighter seal and improved airtightness.

[0025] The stainless steel cladding layer 200 has circumferentially formed reinforcing strips 210 on its surface. Both the stainless steel cladding layer 200 and the reinforcing strips 210 are coated with a wear-resistant coating 211. This wear-resistant coating 211 can be a titanium nitride coating to increase surface wear resistance. The reinforcing strips 210 increase overall bending strength, thereby extending service life. The protective layer assembly 310 includes a corrosion-resistant coating 311 and an anti-oxidation coating 312. The corrosion-resistant coating 311 is plated on the surface of the conductive rod 100, and the anti-oxidation coating 312 is plated on the surface of the corrosion-resistant coating 311. Here, the corrosion-resistant coating 311 is an epoxy resin coating to enhance corrosion resistance, and the anti-oxidation coating 312 is a nickel-based alloy coating to increase oxidation resistance and improve service life. The overall thickness of the protective layer assembly 310 is 0.05-0.1 mm to balance conductivity and corrosion resistance.

[0026] The reinforcing layer 330 includes several annular steel wires 331 and several transverse steel wires 332. The transverse steel wires 332 are circumferentially fixed on the several annular steel wires 331. The several annular steel wires 331 and several transverse steel wires 332 are placed in the corrosion-resistant sealing layer 320. Adding the reinforcing layer 330 to the corrosion-resistant sealing layer 320 can increase the overall toughness and strength, thereby helping to improve the service life.

[0027] Specifically, the structural principle of the conductive rod for the electrolytic electrode plate with durable and stable corrosion resistance and conductivity is as follows: By setting a composite protective structure 300 between the stainless steel cladding layer 200 and the conductive rod 100, the protective layer group 310 and the corrosion-resistant sealing layer 320 can improve the corrosion resistance and oxidation resistance during use. At the same time, the addition of a reinforcing layer 330 inside the corrosion-resistant sealing layer 320 and the formation of reinforcing strips 210 on the surface of the stainless steel cladding layer 200 can increase the overall bending strength. This arrangement is beneficial to increasing the overall corrosion resistance, oxidation resistance and wear resistance, reducing the possibility of breakage, and also improving the overall service life and conductor efficiency.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
