Description

Technical Field

[0001] This application relates to the field of lightning protection and grounding technology for towers, and in particular to a method and device for adaptive soil condition control. Background Technology

[0002] The grounding electrode of a power pole is a metal conductor (commonly made of galvanized steel or copper) buried underground and in direct contact with the soil. It is the core discharge carrier of the power pole lightning protection grounding system, which can evenly diffuse the lightning current and fault current transmitted from the grounding lead into the soil, ensuring that the grounding resistance is within the safe threshold and preventing high-potential backflash damage to transmission equipment. However, in acidic soils (pH<5.5), the annual corrosion rate of galvanized steel is greater than 0.5 mm; in high-salt and alkaline areas, the grounding resistance of the soil fluctuates by more than 50%; and in permafrost areas, the soil current dissipation efficiency decreases by 60%. The grounding electrode is difficult to adapt to different soil environments, has poor environmental adaptability, and it is difficult to balance conductivity and durability.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0008] In one embodiment, the soil condition adaptive control device further includes a locking mechanism. The inner wall of the double-layer annular airbag is provided with a guide groove in the vertical direction. The depth of the guide groove is greater than the thickness of the protective film and less than the total thickness of the conductive ring and the protective film. The width of the guide groove matches the diameter of the grounding lead. The locking mechanism is provided on both sides of the guide groove. The locking mechanism is used to fix the grounding lead in the guide groove so that the grounding lead and the conductive ring can make electrical contact.

[0009] In one embodiment, the formulation includes an acidic soil formulation, a saline-alkali soil formulation, a frozen soil formulation, and a general formulation. The acidic soil formulation comprises bentonite, a composite of magnesium oxide and calcium carbonate, graphene powder, and an ion diffusing agent.

[0010] In one embodiment, the conductive ring is prepared using a composite conductive material, which includes a first preset ratio of graphene and a second preset ratio of silicone rubber, wherein the second preset ratio is greater than the first preset ratio, and the conductivity of the conductive ring is greater than or equal to a preset reference conductivity.

[0011] In one embodiment, the protective film is prepared using a composite protective material, which includes polytetrafluoroethylene vinyl body and alumina nanoparticles. The protective film has an ultraviolet radiation resistance duration greater than a preset reference duration, and the tensile strength of the protective film is greater than a preset reference strength.

[0014] In one embodiment, the step of calculating the release rate of the functional material in the target chamber based on the current resistivity and current pH value of the externally contacting soil includes: Obtain the current resistivity and current pH value of the externally contacted soil, the target resistivity corresponding to the type of the externally contacted soil, and the calibration coefficient, and obtain the correspondence between the current resistivity, current pH value, target resistivity, calibration coefficient and release rate; The release rate of the functional material in the target chamber is determined based on the current resistivity and pH value of the externally contacted soil, the target resistivity corresponding to the type of externally contacted soil, the calibration coefficient, and the corresponding relationship.

[0016] In addition, to achieve the above objectives, this application also proposes a soil state adaptive control device, which includes the soil state adaptive control apparatus as described above and implements the steps of the soil state adaptive control method as described above.

[0017] This application provides a soil state adaptive control device, installed at the grounding end of the grounding lead in the grounding body of a tower, including a double-layer annular airbag and a control module. The double-layer annular airbag includes a conductive ring and a protective film coated on the outer surface of the conductive ring.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0024] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The main solution of this application embodiment is: a soil state adaptive control device is installed at the grounding end of the grounding lead in the tower grounding body, including a double-layer annular airbag and a control module. The double-layer annular airbag includes a conductive ring and a protective film coated on the outer surface of the conductive ring. The conductive ring has a sandwich cavity, which is divided into multiple independent chambers. Different chambers store functional materials with different formulations. The control module is used to determine the target formulation based on the type of external contact soil, determine the target chamber among the multiple chambers based on the target formulation, calculate the release rate of the functional material in the target chamber based on the current resistivity and current pH value of the external contact soil, and control the release of the functional material in the target chamber into the external contact soil based on the release rate, so as to dynamically adjust the electrochemical state of the external contact soil.

[0026] This application provides a solution that selects appropriate functional materials based on soil type and releases them into the soil to adaptively adjust the soil resistivity and pH value, dynamically balance ion concentration, improve the electrical conductivity of the soil around the grounding electrode, ensure the conductivity of the grounding electrode, and simultaneously dynamically balance the acidity and alkalinity to slow down the corrosion rate of the grounding electrode, extend the service life of the grounding electrode, and ensure the durability of the grounding electrode. This solves the technical problem that grounding electrodes are difficult to adapt to different types of soil environments and difficult to guarantee conductivity and durability.

[0027] This application provides a soil condition adaptive control device, referring to... Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the soil condition adaptive control device of this application.

[0028] In this embodiment, the soil condition adaptive control device is installed at the grounding end of the grounding lead in the tower grounding body, including a double-layer annular airbag 10 and a control module 20. The double-layer annular airbag 10 includes a conductive ring 101 and a protective film 102 coated on the outer surface of the conductive ring. The conductive ring 101 has a sandwich cavity 103 inside, which is divided into multiple independent chambers 1031. Different chambers 1031 store functional materials with different formulations.

[0029] It should be noted that the grounding end of the grounding lead is usually buried in the soil. The grounding end of the grounding lead is fixed in the soil condition adaptive control device, which can be buried in the soil together with the grounding end of the grounding lead.

[0030] It is understood that the double-layer annular airbag 10 of this embodiment adopts a double-layer structure of an inner conductive ring and an outer protective film. The interlayer cavity 103 is divided into multiple chambers 1031. The number of chambers (at least 2, for example: 6) and the volume of the chambers (for example: 50mL±5mL) can be flexibly adjusted according to actual needs, and there is no specific limitation on this. Each chamber 1031 is independent and can be pre-filled with functional materials of different formulations. The control module 20 can be set on the outer wall of the double-layer annular airbag 10.

[0031] In one feasible implementation, the conductive ring 101 is prepared using a composite conductive material, which includes a first preset ratio of graphene and a second preset ratio of silicone rubber, wherein the second preset ratio is greater than the first preset ratio, and the conductivity of the conductive ring is greater than or equal to a preset reference conductivity.

[0032] It should be noted that the composite conductive material is a composite material of graphene and silicone rubber, with graphene accounting for a first preset proportion and silicone rubber accounting for a second preset proportion. Both the first and second preset proportions are preset mass percentages / weight percentages (wt%) of each component, and the second preset proportion is usually greater than the first preset proportion. For example, the first preset proportion is set to 15 wt% and the second preset proportion is set to 85 wt%, in which case the composite conductive material consists of 15 wt% graphene and 85 wt% silicone rubber.

[0033] Additionally, it should be noted that the thickness of the conductive ring 101 is typically 3mm, but due to a certain error (0.2mm), the actual thickness range is 2.8mm to 3.2mm. The preset reference conductivity is the pre-set conductivity (volume conductivity) that the conductive ring 101 needs to achieve, usually set to 100S / m, meaning that the volume conductivity of the conductive ring 101 is greater than or equal to 100S / m.

[0034] Understandably, the inner conductive ring 101 is made of a high-conductivity composite conductive material and has conductive function. By placing the conductive ring 101 on the grounding lead, an axial electric field gradient can be constructed, reducing current dissipation impedance and allowing lightning current or fault current to be more efficiently conducted into the surrounding soil. The optimized three-dimensional electric field model is then:

[0035] In the formula, The gradient operator (Hamiltonian operator) is used to characterize the rate of change in space. Electrical conductivity, measured in S / m, is used to characterize electrical conductivity. Electric potential (V) is used to characterize the electric potential distribution around a grounding electrode. Represents the electric field strength (negative gradient), with units of V / m. It is the rate of change of electric potential in space, i.e., electric field strength. It represents current density, with units of A / m², and is the differential form of Ohm's law, used to characterize the current passing through a unit area. The divergence of current density, measured in A / m³, characterizes the net outflow of current per unit volume and reflects the degree of current convergence or divergence. Space charge density, expressed in C / m³, is used to characterize the volumetric density of free charges (such as ions and electrons) accumulated in soil or materials. This represents the rate of change of charge density over time, measured in C / (m³·s), reflecting the rate of charge accumulation (greater than 0) or consumption (less than 0) in a local area. Using the soil condition adaptive control device of this embodiment, the soil conductivity can be increased from its original value to 0.8~1.2 S / m.

[0036] In one feasible implementation, the protective film 102 is prepared using a composite protective material, which includes polytetrafluoroethylene vinyl body and alumina nanoparticles. The duration of ultraviolet radiation resistance of the protective film is greater than a preset reference duration, and the tensile strength of the protective film is greater than a preset reference strength.

[0037] It should be noted that the composite protective material is composed of a polytetrafluoroethylene (PTFE) matrix and alumina (Al2O3) nanoparticles. Specifically, the composite protective material uses PTFE as the matrix and alumina nanoparticles as the reinforcing phase, which are uniformly dispersed within the PTFE matrix. The thickness of the protective film 102 is typically 0.5 mm, but due to a certain error (0.05 mm), the actual thickness range is 0.45 mm to 0.55 mm.

[0038] Additionally, it should be noted that the preset reference duration is the pre-set UV irradiation resistance time that the protective film 102 needs to achieve, typically set to 2000 hours, meaning the UV irradiation resistance time of the protective film 102 is greater than 2000 hours. The preset reference strength is the pre-set strength that the protective film 102 needs to achieve, typically set to 15 MPa, meaning the tensile strength of the protective film 102 is greater than 15 MPa.

[0039] Understandably, the outer protective film 102 is made of a composite protective material of PTFE and Al2O3 nanoparticles, which can resist physical erosion (such as stone puncture, soil frost heave stress) and chemical erosion (such as acid and alkali corrosion, ultraviolet aging) from the external environment, protect the inner conductive ring 101 and internal functional materials, and ensure that the soil condition adaptive control device can be used continuously in harsh outdoor environments.

[0040] It should be understood that in this embodiment, the inner conductive ring 101 is responsible for efficient conductivity, and the outer protective film 102 is responsible for long-term protection, ensuring the conductivity and durability of the soil condition adaptive control device.

[0041] In this embodiment, the control module 20 is used to determine the target formulation based on the type of external contact soil, determine the target chamber among multiple chambers based on the target formulation, calculate the release rate of the functional material in the target chamber based on the current resistivity and current pH value of the external contact soil, and control the release of the functional material in the target chamber into the external contact soil based on the release rate, so as to dynamically adjust the electrochemical state of the external contact soil.

[0042] It should be noted that the formulations in this embodiment include acidic soil formulations, saline-alkali soil formulations, frozen soil formulations, and general formulations. In specific implementation, at least two of the functional materials corresponding to the formulations are injected into the chamber 1031.

[0043] Acidic soil formulations are specifically designed for acidic soils, defined as soils with a pH value less than 5.5 and a resistivity less than 200 Ω·m. The components of an acidic soil formulation include bentonite, a magnesium oxide / calcium carbonate composite (MgO / CaCO3 composite), graphene powder, and an ion diffusing agent. The mass percentages of bentonite, MgO / CaCO3 composite, graphene powder, and ion diffusing agent are 30 wt%, 35 wt%, 15 wt%, and 20 wt%, respectively. In the MgO / CaCO3 composite, the mass percentage of magnesium oxide (MgO) is 30 wt%, and the mass percentage of calcium carbonate (CaCO3) is 70 wt%. The MgO / CaCO3 composite can undergo an acid-base balance reaction in acidic soils. , It is a hydrogen ion. Magnesium ions, For water, It is magnesium oxide. Functional materials formulated for acidic soils can increase the pH value of acidic soils by at least 0.5 per month.

[0044] A saline soil formula is a formula designed for saline soil, and an alkaline soil formula is a formula designed for alkaline soil. In this embodiment, the saline soil formula and the alkaline soil formula are the same and can be collectively referred to as the saline-alkali soil formula, that is, a formula designed for saline-alkali soil. Here, saline-alkali soil refers to soil with a pH value greater than 8.5 and a chloride ion concentration of 100 mg / L. -Soils with a concentration greater than 1000 mg / kg. The saline-alkali soil formulation consists of bentonite, a compound of sulfur and potassium dihydrogen phosphate (sulfur / potassium dihydrogen phosphate compound), graphene powder, and an ion diffusing agent. The mass percentages of bentonite, sulfur / potassium dihydrogen phosphate compound, graphene powder, and ion diffusing agent are 40 wt%, 25 wt%, 10 wt%, and 25 wt%, respectively. In the sulfur / potassium dihydrogen phosphate compound, the mass percentage of sulfur is 40 wt%, and the mass percentage of potassium dihydrogen phosphate is 60 wt%. Under the catalysis of the ion diffusing agent, the sulfur (elemental sulfur) in the compound gradually undergoes an oxidation reaction. , It is sulfur. For oxygen, For water, The resulting dilute sulfuric acid (H₂SO₄) reacts with excess sodium hydroxide (NaOH), sodium carbonate (Na₂CO₃), and other free hydroxide ions (OH⁻) in the soil. - The compound undergoes a neutralization reaction, and the potassium dihydrogen phosphate in it acts as a pH buffer, preventing excessive local H2SO4 concentrations from causing an excessive drop in soil pH, thus ensuring that the soil pH is stably controlled within the optimal neutral range of 6.0 to 8.0. Functional materials formulated according to the saline-alkali soil formula can reduce the soil pH by at least 0.4 per month.

[0045] Frozen soil formulations are formulations specifically designed for frozen soil, which refers to soil at an altitude greater than 3000m and a temperature less than [missing information]. Soil at 10℃. The frozen soil formulation consists of bentonite, graphene powder, sodium chloride (NaCl) antifreeze, and ion diffusing agent, with the following mass percentages: bentonite, graphene powder, NaCl antifreeze, and ion diffusing agent being 20wt%, 30wt%, 40wt%, and 10wt%, respectively.

[0046] The general-purpose formula is suitable for most conventional soils that do not possess extreme environmental characteristics (strong acid, strong alkali, high salinity, permafrost). The general-purpose formula consists of bentonite, MgO / CaCO3 composite agent, sulfur / potassium dihydrogen phosphate composite agent, graphene powder, and ion diffusing agent. The mass percentages of bentonite, MgO / CaCO3 composite agent, sulfur / potassium dihydrogen phosphate composite agent, graphene powder, and ion diffusing agent are 35wt%, 15wt%, 10wt%, 20wt%, and 20wt%, respectively. The general-purpose formula also contains small amounts of MgO / CaCO3 composite agent and sulfur / potassium dihydrogen phosphate composite agent to handle moderate fluctuations in soil pH (e.g., pH between 6.0 and 8.0).

[0047] Understandably, the core release agents in the formula are MgO / CaCO3 composite, sulfur / potassium dihydrogen phosphate composite, and NaCl antifreeze, which are "active ingredients" that can directly regulate soil pH, ion concentration, and freezing point. Graphene powder acts as a conductivity enhancer; some migrates during the release process, but its more crucial role is to form a stable three-dimensional conductive network within the interlayer cavity, reducing contact resistance. Bentonite provides a carrier for water absorption, moisture retention, and thickening, while the ion diffusing agent is specifically responsible for carrying and promoting the diffusion of active ions to more distant parts of the soil, expanding the area of ​​improvement.

[0048] Additionally, it should be noted that the external contact soil refers to the soil that the soil condition adaptive control device can access. Based on the type of external contact soil, the appropriate formula, i.e., the target formula, can be determined. Specifically, if the control module 20 detects an altitude greater than 3000m and a current temperature less than... If the temperature is 10℃, the soil type in contact with the outside is considered frozen soil, and the target formula is a frozen soil formula. If the control module 20 detects that the current pH value is less than 5.5 and the resistivity is less than 200 Ω·m, the soil type in contact with the outside is considered acidic soil, and the target formula is an acidic soil formula. If the control module 20 detects that the current pH value is greater than 8.5 and / or Cl... - If the concentration is greater than 1000 mg / kg, the soil type in external contact is considered to be saline-alkali soil, and the target formula is a saline-alkali soil formula; otherwise, the soil type in external contact is considered to be conventional soil, and the target formula is a general formula. The control module 20 uses the chamber storing the functional materials corresponding to the target formula as the target chamber.

[0049] Understandably, after determining the target chamber, it is necessary to calculate the release rate of the functional material within the target chamber. The release rate can be calculated based on the current resistivity and pH value of the soil in contact with the outside, as shown in the following formula:

[0050] In the formula, This indicates the release rate (in g / month). This indicates the amount of material released (in grams). Indicates the release period (usually calculated in months). This represents the target resistivity (in Ω·m), which is the desired resistivity and is usually determined based on the type of soil in contact with the external environment. Indicates the current resistivity. Indicates the current pH value. , , Indicates the measured calibration coefficient, for example: It is 0.15. It is 0.12. It is 0.18.

[0051] It should be understood that the control module 20 releases the functional material in the target chamber into the external contact soil according to the release rate, so as to dynamically adjust the electrochemical state of the external contact soil. The electrochemical state in this embodiment includes at least pH value and resistivity (or conductivity). Here, the release of functional material refers to the slow and controllable penetration and diffusion of the effective components (ions, molecules) of functional material into the surrounding soil environment under the action of water, and its physical form can be the migration of solution, colloid or fine particles.

[0052] In one feasible implementation, the control module 20 includes a sensing unit, a calculation unit, and an execution unit. The sensing unit and the execution unit are disposed on the outer wall of the double-layered annular airbag 10, and the calculation unit is connected to the sensing unit and the execution unit respectively. The sensing unit is used to measure the current resistivity and current pH value of the externally contacting soil; the calculation unit is used to calculate the release rate of the functional material in the target chamber based on the current resistivity and current pH value of the externally contacting soil and the target resistivity corresponding to the type of externally contacting soil, and send a control signal corresponding to the release rate to the execution unit; the execution unit is used to release the functional material in the target chamber into the externally contacting soil based on the control signal.

[0053] It should be noted that the sensing unit includes a resistivity sensor and a pH sensor, used to measure the volume resistivity and pH value of the externally contacting soil, respectively. The real-time measured volume resistivity of the externally contacting soil is the current resistivity, and the real-time measured pH value of the externally contacting soil is the current pH value. The probes of the resistivity sensor and the pH sensor are embedded in the outer wall of the double-layered annular airbag 10, in direct contact with the soil. The computing unit can use a low-power embedded microcontroller (MCU) with the release kinetic equation (i.e., the calculation relationship used to calculate the release rate) programmed into it.

[0054] Additionally, it should be noted that the double-layered annular airbag 10 is provided with multiple filling holes, each corresponding to a specific chamber. When the filling holes are open, they connect chamber 1031 to the external soil. The execution unit includes multiple solenoid valves, with one solenoid valve for each filling hole. The solenoid valves are used to adjust the opening degree of the filling hole in the target chamber based on control signals, so that the functional material in the target chamber is released into the external soil through the filling hole.

[0055] Understandably, the calculation unit controls the sensing unit to collect the current resistivity and pH value according to a preset cycle (e.g., per hour). After obtaining the current resistivity and pH value, it substitutes them into the release kinetic equation to calculate the theoretical release rate required at that time, and converts this release rate into a control signal for the execution unit. Specifically, the calculation unit can control the opening duty cycle of the solenoid valve through a PWM (Pulse Width Modulation) signal. The release rate is directly proportional to the opening time of the solenoid valve. The higher the calculation rate, the longer the single opening time of the solenoid valve, or the faster the opening frequency. When the solenoid valve is fully open, the opening degree is 100%; when the solenoid valve is closed, the opening degree is 0%.

[0056] It should be understood that after the soil condition adaptive control device is activated by water injection, water enters the chamber through the filling hole opened in the double-layered annular airbag 10, partially dissolving the solid functional material or forming a colloidal suspension. Driven by the concentration gradient (diffusion) and soil capillary suction, material ions or tiny particles slowly and continuously permeate and diffuse into the outer soil layer through the filling hole. The released functional material first fills the tiny gaps between the outer wall of the airbag and the grounding lead / soil, and then, with the help of irrigation water and groundwater flow, further migrates to more distant soil layers, thereby improving soil properties over a wide area.

[0057] In one feasible implementation, the control module 20 is further configured to adjust the release rate based on a preset multiplier when any one of the following conditions is met: the current resistivity is greater than a preset resistivity threshold, the current pH value is less than a first preset pH threshold, and the current pH value is greater than a second preset pH threshold. The first preset pH threshold is less than the second preset pH threshold.

[0058] It should be noted that the preset resistivity threshold is a pre-defined resistivity threshold, typically set to 100 Ω·m (according to the power industry grounding design specifications). Both the first and second preset pH thresholds are pre-defined pH values. The first preset pH threshold is usually lower than the second. The first preset pH threshold can be set to 5.5, corresponding to the acid corrosion critical point where the annual corrosion rate of galvanized steel exceeds 0.5 mm. The second preset pH threshold can be set to 8.5, corresponding to the alkali damage threshold where the resistivity fluctuation of saline-alkali land exceeds 50%. The preset multiplier is a pre-set multiplier, typically 300%.

[0059] Understandably, when the current resistivity of the soil in contact with the external environment is detected to be greater than 100 Ω·m, or the current pH value is less than 5.5 or greater than 8.5, the control module 20 determines that the current soil environment is in a deteriorated state of conductivity failure or increased corrosion risk. At this time, the accelerated material release mode is immediately triggered. The original release rate calculated according to the release kinetic equation is multiplied by 300%, and a corresponding control signal is sent to the execution unit according to the adjusted release rate, causing the material infiltration rate to jump to three times the normal level. The accelerated release will continue until a retest confirms that the current resistivity has dropped to 100 Ω·m or below and the current pH value has recovered to between 5.5 and 8.5, at which point it automatically returns to the normal release mode, thus forming a fully automatic closed-loop control process of "monitoring-triggering-accelerated release-improvement-recovery". Among them, the actuator can significantly increase the material infiltration flux by adjusting the opening of the filling hole to the maximum or by slightly increasing the pressure in the chamber through an electric heating device.

[0060] Further reference Figure 2 The soil condition adaptive control device also includes a locking mechanism 30. The double-layer annular airbag 10 has a guide groove 104 in the vertical direction. The depth of the guide groove 104 is greater than the thickness of the protective film 102 and less than the total thickness of the conductive ring 101 and the protective film 102. The width of the guide groove 104 matches the diameter of the grounding lead. Locking mechanisms 30 are provided on both sides of the guide groove 104. The locking mechanism 30 is used to fix the grounding lead in the guide groove 104 so that the grounding lead and the conductive ring 101 can make electrical contact.

[0061] It should be noted that the depth of the guide groove 104 is greater than the thickness of the protective film 102 but less than the total thickness of the conductive ring 101 and the protective film 102. This ensures that after the grounding lead is embedded in the guide groove 104, it directly contacts the conductive ring, rather than the protective film 102. Simultaneously, the width of the guide groove 104 needs to match the diameter of the grounding lead (typically 18-22 mm). The grounding lead can be flat steel or round steel; no specific limitation is made.

[0062] Additionally, it should be noted that locking mechanisms 30 are provided on both sides of the guide groove 104. These locking mechanisms 30 can be stainless steel spring clips (angle 120°±5°), capable of automatically resetting based on their own elasticity and tightly gripping the grounding lead. The arc design of the stainless steel spring clips can adapt to grounding lead diameters of 18-22mm. For disassembly, tools can be used to pry open the stainless steel spring clips. During installation, align the opening of the soil condition adaptive control device with the vertical grounding lead of the tower, and push or snap it in horizontally from the side, ensuring the grounding lead is fully embedded in the groove of the inner conductive ring, achieving tight physical and electrical contact. Multiple locking mechanisms 30 can be provided; no specific limitation is made.

[0063] In addition, in order to ensure that the double-layer annular airbag 10 can cover the grounding lead, the double-layer annular airbag 10 can be provided with an opening, adopting an open design rather than a closed ring.

[0064] In practice, a grounding pit is excavated to the designated location (dimensions: 0.8m × 0.8m × 1.2m). The soil condition adaptive control device is then fitted onto the grounding lead, and the stainless steel spring clips automatically lock in place. Clean water is poured in to activate the material, and the soil is backfilled and compacted (compacted density greater than or equal to 1.6g / cm³). This completes the installation of the soil condition adaptive control device. The installation process requires no complex operations such as welding or bolt tightening, and the installation time is relatively short. Compared to the traditional drag-reducing agent process, which requires several hours or even days of excavation, mixing, pouring, and curing, the efficiency is greatly improved.

[0065] For a plateau permafrost region with a resistivity of 450 Ω·m and a pH of 8.2, if a traditional resistance-reducing agent is used, the initial grounding resistance is 18 Ω, the resistance increases by 52% after freeze-thaw cycles, and the lightning strike temperature rise (30 kA) is 226°C. If the soil condition adaptive control device of this embodiment is used, the initial grounding resistance is 3.8 Ω, the resistance increases by 4.2 Ω after freeze-thaw cycles, and the lightning strike temperature rise (30 kA) is 75°C. Compared with the traditional resistance-reducing agent scheme, the stability of the grounding resistance is improved by 12 times, and the lightning strike temperature rise is reduced by 66.8%.

[0066] refer to Figure 3 When installing the soil condition adaptive control device of this embodiment in permafrost areas, the grounding electrode needs to be pre-treated first. This involves grinding the grounding electrode to a metallic luster (Sa2.5 grade) and coating it with a zinc-based anti-corrosion layer (thickness ≥80μm). Then, gel is filled in layers. The first layer: fill the gel to 1 / 3 of the grounding trench depth, compacting it to a density ≥1.8g / cm³ to form a stable supporting base. The grounding lead (grounding electrode) is then vertically inserted into the first layer. The second layer: surround the electrode, filling the trench with the remaining gel (i.e., the remaining 2 / 3 of the total depth), compacting it again to ensure the electrode is completely covered without voids, and then activating it with 5L / m³ of water. Then, the antifreeze agent is activated. Construction in permafrost areas must be carried out at temperatures above -5℃. The gel moisture content must be controlled at 35±2%; too low a moisture content reduces conductivity, while too high a moisture content easily leads to frost heave. The grounding electrode burial depth should be greater than the upper limit of the permafrost layer +0.5m, and the grounding trench width should be greater than or equal to 0.6m to avoid deformation due to permafrost compression.

[0067] For coastal saline-alkali land, if the soil condition adaptive regulation device of this embodiment is used to release the functional materials corresponding to the saline-alkali soil formula, the soil pH can be reduced from 9.1 to 7.0±0.3 after 6 months. - The concentration decreased by 65%, and the grounding resistance stabilized at 4.1Ω (reduction > 80%).

[0068] refer to Figure 4When installing the soil condition adaptive control device of this embodiment on saline-alkali land, the soil needs to be pretreated first, namely, tilling and loosening the soil (depth greater than or equal to 40cm), applying a soil conditioner (e.g., gypsum, dosage: 25kg / m²), and rotary tilling for mixing. The coefficient of variation (CV) is used to quantify the uniformity of the soil conditioner distribution. It is defined as: CV = (standard deviation of soil conditioner content / average value) × 100%. The smaller the CV value, the more uniform the soil conditioner distribution and the more consistent the treatment effect. Setting CV < 15% as the acceptance standard is an important quality control measure to ensure the consistency of the subsequent leaching and electrochemical treatment effects. After completing the soil treatment, gradient leaching and electrochemical enhancement are then carried out.

[0069] In practical implementation, after a 100kA lightning current impact, the rate of change in grounding resistance is less than or equal to 5%. After 100 freeze-thaw cycles at 40℃, the rupture rate of the double-layer annular airbag is <0.1%; when used continuously in soil with a pH of 4.0, the corrosion weight loss rate is less than or equal to 0.01 mm / year.

[0070] This embodiment provides a soil condition adaptive control device, installed at the grounding end of the grounding lead in the grounding electrode of a tower. It includes a double-layer annular airbag and a control module. The double-layer annular airbag includes a conductive ring and a protective film coated on the outer surface of the conductive ring. The conductive ring has a sandwich cavity, which is divided into multiple independent chambers. Different chambers store functional materials with different formulations. The control module determines a target formulation based on the type of externally contacting soil, identifies a target chamber among the multiple chambers based on the target formulation, calculates the release rate of the functional material in the target chamber based on the current resistivity and pH value of the externally contacting soil, and controls the release of the functional material from the target chamber into the externally contacting soil based on the release rate, thereby dynamically adjusting the electrochemical state of the externally contacting soil. This embodiment selects appropriate functional materials to release into the soil according to the soil type, adaptively adjusts the soil resistivity and pH value, dynamically balances ion concentration, increases the conductivity of the soil around the grounding electrode, ensures the conductivity of the grounding electrode, and simultaneously dynamically balances pH, slows down the corrosion rate of the grounding electrode, extends its service life, and ensures its durability.

[0071] This application provides a method for preparing a soil condition adaptive regulation device, referring to... Figure 5 , Figure 5 This is a schematic flowchart of the first embodiment of the preparation method of the soil state adaptive control device of this application.

[0072] In this embodiment, the preparation method of the soil condition adaptive regulation device includes steps A11 to A14: Step A11: Injection molding the composite conductive material to form a conductive ring; It should be noted that the preparation method of this embodiment is applied to the soil state adaptive control device in the above embodiment. For the same or similar contents as those in the above embodiment, please refer to the above description, and it will not be repeated hereafter.

[0073] Understandably, the first step is the inner layer molding: 15wt% graphene and 85wt% silicone rubber are mixed to form a composite conductive material, and the inner conductive ring is made by injection molding (curing at 180℃±5℃).

[0074] Step A12: Spray a composite protective material onto the outer surface of the conductive ring to form a protective film; It should be understood that the second step is the outer layer coating: a composite protective material of PTFE and Al2O3 nanoparticles is coated onto the outer surface of the inner conductive ring using plasma spraying technology to form an outer protective film. The power of the spraying equipment can be set to 300W, and the speed can be set to 0.2mm / min. Although the inner and outer layers are composited in steps, the final result is an inseparable integral ring, not two independent parts.

[0075] Step A13: Weld multiple independent chambers in the conductive ring, and inject functional materials with different formulations into each chamber through the reserved filling hole to obtain a double-layer annular airbag. Understandably, the third step is chamber partitioning and filling sealing: In the conductive ring, partition plates are welded using laser welding technology to form multiple independent chambers, functional materials with different formulations are injected into each chamber, and the filling holes of each chamber are closed to obtain the final double-layer annular airbag.

[0076] Step A14: Integrate the control module onto the double-layered annular airbag.

[0077] It should be understood that the fourth step is control integration: integrating the control module on the double-layered annular airbag to form a complete soil condition adaptive regulation device.

[0078] This embodiment provides a method for preparing a soil condition adaptive control device. A conductive ring is formed by injection molding a composite conductive material; a protective film is formed by spraying a composite protective material onto the outer surface of the conductive ring; multiple independent chambers are welded into the conductive ring, and functional materials with different formulations are injected into each chamber through pre-reserved filling holes to obtain a double-layered annular airbag; a control module is integrated onto the double-layered annular airbag. The resulting soil condition adaptive control device can select appropriate functional materials to release into the soil according to the soil type, adaptively adjust the soil resistivity and pH value, dynamically balance ion concentration, increase the conductivity of the soil around the grounding electrode to ensure the conductivity of the grounding electrode, and simultaneously dynamically balance the pH to slow down the corrosion rate of the grounding electrode, extend its service life, and ensure its durability.

[0079] This application provides a method for adaptive control of soil conditions, referring to... Figure 6 , Figure 6 This is a flowchart illustrating the first embodiment of the soil state adaptive control method of this application.

[0080] In this embodiment, the soil condition adaptive regulation method includes steps S10 to S40: Step S10: Determine the target formulation based on the type of externally contacting soil; It should be noted that this embodiment applies to a soil condition adaptive control device, which includes a double-layer annular airbag, a control module, and a locking mechanism. For details, please refer to [reference needed]. Figures 1 to 2 .

[0081] Additionally, it should be noted that the external contact soil refers to the soil that the soil condition adaptive control device can access. Based on the type of external contact soil, the appropriate formulation to be used, i.e., the target formulation, can be determined. The target formulation is typically determined from formulations for acidic soils, saline-alkali soils, frozen soils, and general-purpose formulations.

[0082] Specifically, if an altitude greater than 3000m is detected and the current temperature is less than... If the temperature is 10℃, the soil type in contact with the outside is considered frozen soil, and the target formula is a frozen soil formula. If the control module 20 detects that the current pH value is less than 5.5 and the resistivity is less than 200 Ω·m, the soil type in contact with the outside is considered acidic soil, and the target formula is an acidic soil formula. If the control module 20 detects that the current pH value is greater than 8.5 and / or Cl... - If the concentration is greater than 1000 mg / kg, the type of soil in external contact is considered to be saline-alkali soil, and the target formula is a saline-alkali soil formula; otherwise, the type of soil in external contact is considered to be conventional soil, and the target formula is a general formula.

[0083] Acidic soil formulations are specifically designed for acidic soils, defined as soils with a pH value less than 5.5 and a resistivity less than 200 Ω·m. The components of an acidic soil formulation include bentonite, a magnesium oxide / calcium carbonate composite (MgO / CaCO3 composite), graphene powder, and an ion diffusing agent. The mass percentages of bentonite, MgO / CaCO3 composite, graphene powder, and ion diffusing agent are 30 wt%, 35 wt%, 15 wt%, and 20 wt%, respectively. In the MgO / CaCO3 composite, the mass percentage of magnesium oxide (MgO) is 30 wt%, and the mass percentage of calcium carbonate (CaCO3) is 70 wt%. The MgO / CaCO3 composite can undergo an acid-base balance reaction in acidic soils. , It is a hydrogen ion. Magnesium ions, For water, It is magnesium oxide. Functional materials formulated for acidic soils can increase the pH value of acidic soils by at least 0.5 per month.

[0084] A saline soil formula is a formula designed for saline soil, and an alkaline soil formula is a formula designed for alkaline soil. In this embodiment, the saline soil formula and the alkaline soil formula are the same and can be collectively referred to as the saline-alkali soil formula, that is, a formula designed for saline-alkali soil. Here, saline-alkali soil refers to soil with a pH value greater than 8.5 and / or chloride ion concentration greater than 10%. - Soils with a concentration greater than 1000 mg / kg. The saline-alkali soil formulation consists of bentonite, a compound of sulfur and potassium dihydrogen phosphate (sulfur / potassium dihydrogen phosphate compound), graphene powder, and an ion diffusing agent. The mass percentages of bentonite, sulfur / potassium dihydrogen phosphate compound, graphene powder, and ion diffusing agent are 40 wt%, 25 wt%, 10 wt%, and 25 wt%, respectively. In the sulfur / potassium dihydrogen phosphate compound, the mass percentage of sulfur is 40 wt%, and the mass percentage of potassium dihydrogen phosphate is 60 wt%. Under the catalysis of the ion diffusing agent, the sulfur (elemental sulfur) in the compound gradually undergoes an oxidation reaction. , It is sulfur. For oxygen, For water, The resulting dilute sulfuric acid (H₂SO₄) reacts with excess sodium hydroxide (NaOH), sodium carbonate (Na₂CO₃), and other free hydroxide ions (OH⁻) in the soil. - The compound undergoes a neutralization reaction, and the potassium dihydrogen phosphate in it acts as a pH buffer, preventing excessive local H2SO4 concentrations from causing an excessive drop in soil pH, thus ensuring that the soil pH is stably controlled within the optimal neutral range of 6.0 to 8.0. Functional materials formulated according to the saline-alkali soil formula can reduce the soil pH by at least 0.4 per month.

[0085] Frozen soil formulations are formulations specifically designed for frozen soil, which refers to soil at an altitude greater than 3000m and a temperature less than [missing information]. Soil at 10℃. The frozen soil formulation consists of bentonite, graphene powder, sodium chloride (NaCl) antifreeze, and ion diffusing agent, with the following mass percentages: bentonite, graphene powder, NaCl antifreeze, and ion diffusing agent being 20wt%, 30wt%, 40wt%, and 10wt%, respectively.

[0086] The general-purpose formula is suitable for most conventional soils that do not possess extreme environmental characteristics (strong acid, strong alkali, high salinity, permafrost). The general-purpose formula consists of bentonite, MgO / CaCO3 composite agent, sulfur / potassium dihydrogen phosphate composite agent, graphene powder, and ion diffusing agent. The mass percentages of bentonite, MgO / CaCO3 composite agent, sulfur / potassium dihydrogen phosphate composite agent, graphene powder, and ion diffusing agent are 35wt%, 15wt%, 10wt%, 20wt%, and 20wt%, respectively. The general-purpose formula also contains small amounts of MgO / CaCO3 composite agent and sulfur / potassium dihydrogen phosphate composite agent to handle moderate fluctuations in soil pH (e.g., pH between 6.0 and 8.0).

[0087] Step S20: Based on the target formulation, determine the target chamber among multiple chambers; It should be noted that the different chambers store functional materials prepared according to different formulas. In this embodiment, the chamber that stores the functional material corresponding to the target formula is designated as the target chamber.

[0088] Step S30: Calculate the release rate of the functional material in the target chamber based on the current resistivity and pH value of the externally contacting soil. Understandably, once the target chamber is determined, it is necessary to calculate the release rate of the functional material in the target chamber. The release rate can be calculated based on the current resistivity and pH value of the soil in external contact.

[0089] In one feasible implementation, step S30 may include steps S301 to S302: Step S301: Obtain the current resistivity and current pH value of the externally contacted soil, the target resistivity corresponding to the type of the externally contacted soil, and the calibration coefficient, and obtain the correspondence between the current resistivity, current pH value, target resistivity, calibration coefficient and release rate. It should be noted that the real-time measured volume resistivity of the externally contacted soil is the current resistivity, and the real-time measured pH value of the externally contacted soil is the current pH value. The target resistivity refers to the resistivity to be achieved, which is usually related to the type of externally contacted soil. The calibration coefficient is a corresponding value measured based on the actual environmental conditions. The correspondence between the current resistivity, current pH value, target resistivity, calibration coefficient, and release rate is the formula for calculating the release rate, which can also be considered as the release kinetic equation, as shown below:

[0090] In the formula, This indicates the release rate (in g / month). This indicates the amount of material released (in grams). Indicates the release period (usually calculated in months). This represents the target resistivity (in Ω·m), which is the desired resistivity and is usually determined based on the type of soil in contact with the external environment. Indicates the current resistivity. Indicates the current pH value. , , Indicates the measured calibration coefficient, for example: It is 0.15. It is 0.12. It is 0.18.

[0091] Step S302: Based on the current resistivity and current pH value of the externally contacted soil, the target resistivity corresponding to the type of externally contacted soil, the calibration coefficient, and the corresponding relationship, determine the release rate of the functional material in the target chamber.

[0092] It should be understood that by substituting the current resistivity of the externally contacting soil, the current pH value of the externally contacting soil, the target resistivity corresponding to the type of externally contacting soil, and the calibration coefficient into the above correspondence, the release rate of the functional material in the target chamber can be calculated.

[0093] Furthermore, in one feasible implementation, after step S302, the method further includes: Step S303: When any one of the following conditions is met, namely, the current resistivity is greater than a preset resistivity threshold, the current pH value is less than a first preset pH threshold, and the current pH value is greater than a second preset pH threshold, the release rate is adjusted based on a preset multiplier, wherein the first preset pH threshold is less than the second preset pH threshold.

[0094] It should be noted that the preset resistivity threshold is a pre-defined resistivity threshold, typically set to 100 Ω·m (according to the power industry grounding design specifications). Both the first and second preset pH thresholds are pre-defined pH values. The first preset pH threshold is usually lower than the second. The first preset pH threshold can be set to 5.5, corresponding to the acid corrosion critical point where the annual corrosion rate of galvanized steel exceeds 0.5 mm. The second preset pH threshold can be set to 8.5, corresponding to the alkali damage threshold where the resistivity fluctuation of saline-alkali land exceeds 50%. The preset multiplier is a pre-set multiplier, typically 300%.

[0095] Understandably, when the current resistivity of the soil in external contact is detected to be greater than 100 Ω·m, or the current pH value is less than 5.5 or greater than 8.5, it is determined that the current soil environment is in a deteriorated state of conductivity failure or increased corrosion risk. At this time, the material accelerated release mode is immediately triggered. The original release rate calculated according to the release kinetic equation is multiplied by 300%, and a corresponding control signal is sent to the execution unit according to the adjusted release rate, so that the material infiltration rate jumps to 3 times the normal level. The accelerated release will continue until the current resistivity is confirmed to drop to 100 Ω·m or below and the current pH value recovers to between 5.5 and 8.5, and then it automatically returns to the normal release mode, thus forming a fully automatic closed-loop control process of "monitoring-triggering-accelerated release-improvement-recovery".

[0096] Step S40: Based on the release rate, control the release of the functional material of the target chamber into the external contact soil to dynamically adjust the electrochemical state of the external contact soil.

[0097] It is understood that, according to the release rate, the functional material in the target chamber is released into the external contact soil to dynamically adjust the electrochemical state of the external contact soil. The electrochemical state in this embodiment includes at least pH value and resistivity (or conductivity). The release of the functional material refers to the slow, controllable penetration and diffusion of the effective components (ions, molecules) of the functional material into the surrounding soil environment under the influence of moisture; its physical form can be the migration of solutions, colloids, or fine particles.

[0098] This embodiment provides a method for adaptive regulation of soil conditions. Based on the type of soil in contact with the external environment, a target formulation is determined. Based on the target formulation, a target chamber is selected from multiple chambers. Based on the current resistivity and pH value of the soil in contact with the external environment, the release rate of functional materials in the target chamber is calculated. Based on the release rate, the release of functional materials from the target chamber into the soil in contact with the external environment is controlled to dynamically regulate the electrochemical state of the soil. This embodiment selects appropriate functional materials to release into the soil according to the soil type, adaptively adjusts the soil resistivity and pH value, dynamically balances ion concentration, increases the conductivity of the soil around the grounding electrode, ensures the conductivity of the grounding electrode, and simultaneously dynamically balances pH to slow down the corrosion rate of the grounding electrode, extend its service life, and ensure its durability.
