Description

Technical Field

[0001] The invention belongs to the technical field of grounding electrode laying, and in particular relates to a vertical laying device for flexible anti-corrosion grounding electrodes in a substation grounding grid. Background Art

[0002] A substation grounding grid is a network structure composed of multiple interconnected conductive grounding electrodes buried at a certain depth. It protects electrical equipment from insulation damage caused by lightning strikes or operational overvoltage, ensuring safe and stable operation. It also provides electrostatic protection and electromagnetic shielding, making it a fundamental component of power system infrastructure. Traditionally, conductive grounding electrodes in substation grounding grids are primarily made of metal (such as galvanized steel and copper). However, metal gradually rusts and degrades after long-term burial, prompting the market to adopt non-metallic materials, such as flexible graphite composite grounding electrodes. However, these electrodes are generally fragile and cannot be directly installed vertically into the ground by hammering or static pressure, as is the case with traditional metal grounding electrodes. Traditional installation methods can easily damage the graphite electrodes, making installation difficult and time-consuming. Furthermore, the current lack of reliable tools and equipment for installing non-metallic grounding electrodes has hindered the widespread adoption of non-metallic grounding materials in substation grounding grids. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a vertical installation device for flexible anti-corrosion grounding electrodes in a substation grounding grid, thereby solving the problems in the above-mentioned background technology.

[0004] The present invention achieves its objectives by providing a vertical installation device for flexible, corrosion-resistant grounding electrodes in a substation grounding grid, comprising a flexible grounding electrode body, a vertical guide mechanism, an anti-corrosion coating structure, and an intelligent monitoring system. The flexible grounding electrode body is wound from multiple strands of copper-plated steel wire to enhance electrical conductivity and mechanical flexibility. The outer surface of the flexible grounding electrode body is coated with a gradient anti-corrosion coating structure to prevent electrochemical corrosion and physical damage. The vertical guide mechanism includes an adjustable-angle drill bit and a hydraulic drive device. A modular connector is connected to the top of the vertical guide mechanism for splicing multiple grounding electrodes and reducing contact resistance. The intelligent monitoring system integrates a distributed corrosion sensor and a wireless transmission module and is embedded within the flexible grounding electrode body. The copper-plated steel wire increases the electrical conductivity to over 85% of pure copper, enhancing flexibility (bending radius ≤ 5D) and adapting to foundation settlement and deformation. The anti-corrosion coating has a comprehensive corrosion protection life of ≥30 years, three times longer than traditional galvanized steel grounding electrodes. The modular connector improves installation efficiency, achieving a contact resistance of ≤0.05Ω and reducing the risk of local overheating. The graphite grounding electrode is protected from damage during installation, making installation effortless and time-saving.

[0005] Furthermore, the gradient anti-corrosion layer structure includes, from the inside to the outside, a zinc-rich epoxy primer layer for sacrificial anode protection of the metal substrate, a conductive polymer intermediate layer for reducing interlayer contact resistance and enhancing adhesion, and a nano-composite anti-oxidation surface layer for enhancing surface wear resistance and oxidation resistance, and the nano-composite anti-oxidation surface layer contains a graphene dispersion with a mass fraction of 3-5%. The zinc powder content of the zinc-rich epoxy primer layer is ≥85%, and the sacrificial anode protection efficiency is ≥95%. The interlayer resistance of the conductive polymer intermediate layer is ≤1Ω·cm. The graphene composite surface layer is used to improve the anti-permeability.

[0006] Furthermore, the adjustable-angle drill bit utilizes a split spiral blade structure, comprising a central main drill bit for directing drilling direction and two symmetrically arranged auxiliary drill bits for correcting deviations in the drilling trajectory. The auxiliary drill bits are connected to the main drill bit via a hinge mechanism. The auxiliary drill bits provide dynamic deviation correction, improving drill bit accuracy. The hinge adjustment mechanism allows for angle adjustment, adapting to complex geological conditions such as hard rock and quicksand. The spiral blades significantly improve chip removal efficiency and reduce the chance of the drill becoming stuck.

[0007] Furthermore, the modular connector utilizes a double-threaded connection structure with a self-sealing conductive paste chamber within and a silicone rubber anti-loosening sleeve wrapped around the outside. The conductive paste chamber communicates with the connection interface via a pressure-releasing membrane. The double-threaded connection enhances tensile strength and prevents loosening. The self-sealing conductive paste reduces contact resistance and shortens curing time. The silicone rubber anti-loosening sleeve enhances aging resistance and improves connection stability in vibrating environments.

[0008] Furthermore, the intelligent monitoring system also includes a soil moisture sensor and a potential difference detection module. The distributed corrosion sensors are arranged in an array. Soil moisture detection is used to optimize the anti-corrosion layer during maintenance cycles. Potential difference monitoring is used to identify potential imbalances in the grounding grid. The array arrangement improves the accuracy of locating corrosion hotspots.

[0009] Furthermore, the system also includes a pressure grouting device consisting of a grouting pipe, a slurry storage tank, and a micro-pressure pump. The grouting pipe is arranged axially along the grounding electrode body and has spirally distributed seepage holes in its wall. The slurry storage tank contains conductive slurry. The spiral seepage holes enhance the resistance reduction effect, ensuring long-term and uniform flow. The micro-pressure pump increases the slurry penetration depth. The slurry storage tank improves construction efficiency.

[0010] The conductive slurry further comprises the following components by weight: 40-50 parts bentonite, which is used to retain water, maintaining a slurry moisture content of 15-20% and a resistivity of ≤0.05 Ω·m; 15-20 parts graphite powder, 8-12 parts sodium-based resistance reducer, 3-5 parts polyacrylamide, and 1-2 parts corrosion inhibitor. The pH is adjusted to 8.5-9.0. A stable pH of 8.5-9.0 can significantly inhibit soil acidification corrosion.

[0011] Furthermore, the hydraulic drive system utilizes a dual-circuit independent control system, including a main propulsion cylinder and a deviation adjustment cylinder. The main propulsion cylinder delivers a thrust of 50kN, accelerating drilling speed in hard rock formations. The deviation adjustment cylinder cooperates with the drill bit to achieve precise guidance. This dual-circuit independent control system improves hydraulic system efficiency and reduces failure rates.

[0012] Furthermore, the system includes an automatic centering mechanism consisting of three sets of circumferentially spaced guide wheels and pressure sensors. The guide wheels are coated with a conductive rubber layer, and the pressure sensors form a closed-loop control system with the hydraulic drive. The three sets of guide wheels have a lateral deflection suppression force of ≥5kN, ensuring dynamic verticality. The surface resistance of the conductive rubber layer is ≤10³Ω, preventing static damage to the anti-corrosion coating. The closed-loop control's correction response time is ≤200ms, significantly reducing the need for manual intervention and freeing up operators' hands, resulting in a high degree of automation.

[0013] Furthermore, the flexible grounding electrode body is connected to a detachable measuring electrode, consisting of a pure copper test head and an insulating sleeve. The test head connects to the body via a magnetic interface. The pure copper test head has a ground resistance measurement error of ≤2%, supporting verification according to the GB / T 17949.1 standard. The magnetic interface and insulating sleeve ensure safety during live testing.

[0014] The beneficial effects of this invention include: The conductivity of the multi-strand copper-coated steel strands is increased to over 85% of that of pure copper, while also enhancing flexibility (bending radius ≤ 5D), allowing for adaptability to foundation settlement and deformation. The anti-corrosion layer boasts a comprehensive corrosion lifespan of ≥30 years, three times longer than traditional galvanized steel grounding electrodes. The modular connector improves installation efficiency, achieving a contact resistance of ≤0.05Ω and reducing the risk of localized overheating. During installation, the graphite grounding electrode is protected from damage, saving effort and significantly reducing construction time. The auxiliary drill bit provides dynamic deviation correction, improving drill bit accuracy. The hinge adjustment mechanism adjusts the angle, adapting to complex geological conditions such as hard rock and quicksand. The spiral blade chip removal system significantly improves chip removal efficiency and reduces the likelihood of drill sticking. The double-threaded connection enhances tensile strength and prevents loosening. The self-sealing conductive paste reduces contact resistance and shortens curing time. The silicone rubber anti-loosening sleeve enhances aging resistance and improves connection stability in vibrating environments. Soil moisture monitoring optimizes the anti-corrosion layer's maintenance cycle. Potential difference monitoring identifies potential imbalances in the grounding grid. The array arrangement improves the accuracy of corrosion hotspot location. The correction cylinder cooperates with the drill bit to achieve precise guidance. The dual oil circuit independent control improves the energy efficiency of the hydraulic system and reduces the failure rate. BRIEF DESCRIPTION OF THE DRAWINGS
