Description

Technical Field

[0001] This utility model relates to the field of deep well anode technology, and more specifically, to a titanium-based noble metal oxide deep well anode with a reinforced connection structure. Background Technology

[0002] Deep well anodes are key components in cathodic protection engineering, primarily used for corrosion protection of underground metal facilities. Their working principle involves applying an external current to make the protected metal structure act as a cathode, thereby inhibiting its electrochemical corrosion process. Deep well anodes are typically installed deep underground, forming an electrochemical circuit with the target metal structure through an electrolyte or soil medium. They offer advantages such as a wide protection range and uniform current distribution, making them particularly suitable for corrosion protection needs of long-distance pipelines or large storage tanks.

[0003] Traditional deep well anodes often use titanium-based noble metal oxides as anode materials. These materials have high conductivity, chemical stability, and corrosion resistance, enabling them to operate for extended periods in harsh underground environments. However, with the increasing complexity of engineering environments, traditional deep well anodes have revealed several problems in practical applications. First, the high interfacial resistance between the anode and the surrounding soil or electrolyte leads to decreased current transmission efficiency, and uneven local current density distribution easily causes material degradation, shortening the anode's lifespan. Second, uneven distribution of formation pressure and construction loads may cause deformation or even fracture of the anode structure, affecting long-term stability. Furthermore, corrosive media such as chloride ions and sulfides in the soil can penetrate to the anode surface, accelerating material oxidation and further reducing the anode's efficiency. Therefore, to address these technical problems, a reinforced titanium-based noble metal oxide deep well anode with a superior connection structure is proposed. Utility Model Content

Through gradient coating of graphite, carbon fiber and polytetrafluoroethylene, the inner layer has high current conductivity to transmit current, the middle layer has current equalization and pressure resistance to maintain structural stability, and the outer layer is sealed, corrosion-resistant and wear-resistant. At the same time, the sliding plate and the toothed plate dynamically mesh and elastically reset, disperse formation pressure and suppress deformation, thereby achieving a comprehensive improvement in the anode's high-efficiency conductivity, impact resistance and corrosion resistance.

[0005] This utility model is achieved through the following technical solution:

[0006] A connection-structure-reinforced titanium-based noble metal oxide deep-well anode, comprising:

[0007] The deep well anode body is externally fixedly equipped with a titanium-based insulating sleeve and a sealing plate, and a performance enhancement mechanism is installed between the deep well anode body and the titanium-based insulating sleeve and sealing plate.

[0008] The gas guide pipe and cable are fixedly connected to the inside of the deep well anode body, and the ends of the gas guide pipe and cable extend out of the deep well anode body.

A sliding plate is slidably connected to one side of the reinforcing plate, and a structural reinforcement mechanism is installed between the sliding plate and the titanium-based insulating sleeve.

[0010] Preferably, there are two sets of sealing plates, which are fixedly connected to the upper and lower ends of the titanium-based insulating sleeve, and the sealing plate at the top is fixedly connected to the upper side of the deep well anode body.

The corrosion-resistant layer is fixedly connected to the outside of the conductive layer and is made of polytetrafluoroethylene material.

[0013] Preferably, the graphite layer, conductive layer, and corrosion-resistant layer are all fixedly connected between the two sets of sealing plates, and the outermost corrosion-resistant layer is fixedly connected to the titanium-based insulating sleeve.

[0014] Preferably, the bottom ends of the gas guide pipe and the cable are placed inside the electrolyte, and the bottom ends of the gas guide pipe and the cable pass through the coke layer, the deep well anode body, the sealing plate at the top, and the reinforcing plate in sequence, protruding outwards.

[0017] The technical solution of this utility model has at least the following beneficial effects:

[0018] This reinforced titanium-based noble metal oxide deep-well anode features a multi-layered encapsulation design consisting of a graphite layer, a carbon fiber conductive layer, and a polytetrafluoroethylene (PTFE) corrosion-resistant layer. This significantly enhances the overall performance of the deep-well anode. The graphite layer is directly bonded to the anode surface, utilizing its high conductivity to ensure efficient current transmission. The carbon fiber conductive layer acts as an intermediate carrier, evenly distributing the current density and preventing material degradation caused by localized overheating. The PTFE corrosion-resistant layer blocks the penetration of corrosive media by sealing surface pores. The synergistic effect of these three layers extends the anode's service life and reduces the risk of polarization. Structurally, the dynamic meshing design of the sliding plate and toothed plate, combined with an elastic reset function, allows the anode to adapt to uneven formation pressure. Stress is released through minute displacements, preventing brittle fracture caused by rigid connections. The multi-stage toothed locking structure distributes the load, suppresses displacement expansion, and ensures structural rigidity under long-term static loads. This design enables the anode to possess high conductivity, resistance to mechanical shock, and resistance to environmental corrosion in complex formations, significantly improving the reliability and economy of cathodic protection projects.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example:

[0025] Please see Figures 1-3This application proposes a reinforced titanium-based noble metal oxide deep well anode, comprising a deep well anode body 1, a gas guide pipe 9, a cable 10, and a reinforcing plate 11. A titanium-based insulating sleeve 4 and a sealing plate 5 are fixedly installed on the outside of the deep well anode body 1. A performance reinforcement mechanism is installed between the deep well anode body 1 and the titanium-based insulating sleeve 4 and the sealing plate 5. The gas guide pipe 9 and the cable 10 are fixedly connected to the inside of the deep well anode body 1, and the ends of the gas guide pipe 9 and the cable 10 extend outside the deep well anode body 1. The reinforcing plate 11 is detachably connected to the upper and lower ends of the titanium-based insulating sleeve 4. A sliding plate 12 is slidably connected to one side of the reinforcing plate 11, and a structural reinforcement mechanism is installed between the sliding plate 12 and the titanium-based insulating sleeve 4.

[0026] There are two sets of sealing plates 5, which are fixedly connected to the upper and lower ends of the titanium-based insulating sleeve 4. The sealing plate 5 located at the top is fixedly connected to the upper side of the deep well anode body 1. The titanium-based insulating sleeve 4 is made of titanium-based material, which has excellent corrosion resistance and mechanical strength, ensuring the long-term stability of the anode in complex formations.

[0027] The lower side of the deep well anode body 1 is fixedly connected to the coke layer 2. The sealing plate 5 located at the bottom of the titanium-based insulating sleeve 4 and the coke layer 2 are filled with electrolyte 3. The combination of coke layer 2 and electrolyte 3 can effectively reduce grounding resistance and optimize the electrochemical interaction between the anode and the surrounding medium.

[0028] The performance enhancement mechanism includes a graphite layer 6, a conductive layer 7, and a corrosion-resistant layer 8. The graphite layer 6 is fixedly connected to the outside of the deep well anode body 1, the coke layer 2, and the electrolyte 3, and the graphite layer 6 is made of graphite material. The conductive layer 7 is fixedly connected to the outside of the graphite layer 6, and the conductive layer 7 is made of carbon fiber composite material. The corrosion-resistant layer 8 is fixedly connected to the outside of the conductive layer 7, and the corrosion-resistant layer 8 is made of polytetrafluoroethylene material. The gradient design of the three layers achieves multiple functions of conductivity, pressure resistance, and corrosion resistance.

[0029] The graphite layer 6, conductive layer 7, and corrosion-resistant layer 8 are all fixedly connected between the two sets of sealing plates 5, and the outermost corrosion-resistant layer 8 is fixedly connected to the titanium-based insulating sleeve 4. The sealing effect of the corrosion-resistant layer 8 effectively blocks the penetration of external corrosive media and extends the service life of the anode.

[0030] The bottom ends of the gas guide pipe 9 and the cable 10 are placed inside the electrolyte 3, and the bottom ends of the gas guide pipe 9 and the cable 10 pass through the coke layer 2, the deep well anode body 1, the top sealing plate 5 and the reinforcing plate 11 in sequence and protrude outward. The design of the gas guide pipe 9 ensures that the gas generated by the anode reaction can be discharged in time to avoid gas accumulation affecting performance.

[0031] A slot 13 is provided on one side of the reinforcing plate 11, and a slider 14 is fixedly connected to one side of the slide plate 12. The slider 14 is limited and slidably connected to the inside of the slot 13. A compression spring 15 is fixedly connected to the inside of the slot 13, and the end of the compression spring 15 is fixedly connected to one side of the slider 14. The elastic reset function of the compression spring 15 enables the slide plate 12 to achieve a slight displacement when the formation pressure changes, thereby releasing local stress.

[0032] The structural reinforcement mechanism includes a first toothed plate 16, a second toothed plate 17, and a bolt 18. The first toothed plate 16 is fixedly connected to one side of the slide plate 12, and the second toothed plate 17 is fixedly connected to the outside of the titanium-based insulating sleeve 4. The first toothed plate 16 and the second toothed plate 17 are interlocked and engaged with each other. The bolt 18 is threadedly connected between the slide plate 12 and the titanium-based insulating sleeve 4. The interlocking design of the first toothed plate 16 and the second toothed plate 17 enhances the deformation resistance of the structure by dispersing the load through multi-stage locking.

[0033] The working principle of the reinforced titanium-based noble metal oxide deep well anode based on the embodiment is as follows: the outer surface of the deep well anode body 1 is sequentially covered with a graphite layer 6, a conductive layer 7, and a corrosion-resistant layer 8, forming a hierarchical protection and conductive path. The graphite layer 6 is directly attached to the surface of the anode body, utilizing its high conductivity to ensure low-loss current transmission to the surrounding soil or electrolyte 3, while simultaneously mitigating oxidation consumption of the anode body through chemical inertness. The conductive layer 7 is composed of carbon fiber composite material, serving as an intermediate carrier for current distribution, preventing excessively high local current density from causing material degradation, and its high tensile strength offsets structural deformation caused by formation pressure, maintaining the interface integrity between the anode and the insulating sleeve. The outermost corrosion-resistant layer 8 is made of polytetrafluoroethylene (PTFE), which completely seals surface pores to block the penetration of corrosive media. Its low coefficient of friction also reduces mechanical wear on the surface caused by soil particle movement. These three layers of materials... Through the interface combination, a synergistic effect is formed. The inner layer ensures the basic conductivity requirements, the middle layer balances the current distribution and mechanical stress, and the outer layer isolates the environment from corrosion, ultimately extending the working life of the anode and reducing the risk of polarization. In addition, in terms of structural reinforcement, the closed cavity formed by the titanium-based insulating sleeve 4 and the sealing plate 5 achieves dynamic stress adjustment through the combination of the detachable reinforcing plate 11 and the sliding plate 12. The sliding plate 12, through the limiting sliding cooperation of the slider 14 and the slot 13, combined with the elastic reset function of the compression spring 15, allows the anode to undergo slight displacement when subjected to uneven ground pressure to release local stress and avoid brittle fracture caused by rigid connection. When the external load increases, the sliding plate 12 drives the first toothed plate 16 to mesh with the second toothed plate 17 fixed to the insulating sleeve, forming a multi-level toothed locking structure. The load is distributed through the contact surface and the displacement expansion is suppressed. The bolt 18 connection provides the final fixation guarantee for the sliding plate 12 and the insulating sleeve. This design enables the anode to adapt to dynamic load changes during construction and installation, while maintaining structural rigidity under long-term static load conditions. At the same time, the gas guide pipe 9 and cable 10 extend to the outside through the coke layer 2 and electrolyte 3, ensuring that the gas generated by the anode reaction is discharged in a timely manner and maintaining a stable electrical connection, avoiding performance degradation caused by gas accumulation or poor contact. The combined filling of coke layer 2 and electrolyte 3 further optimizes the electrochemical interaction between the anode and the surrounding medium, reducing grounding resistance while forming an auxiliary anti-corrosion barrier. Through the interaction of the above materials and structures, the anode achieves a comprehensive improvement in electrochemical efficiency, mechanical reliability and environmental adaptability under harsh working conditions.
