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 of ordinary skill in the art without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

[0051] In the description of this application, it should be noted that, unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this application is for the purpose of describing specific embodiments only and is not intended to limit the application. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In some related technologies, galvanic corrosion caused by rust dripping can be avoided by improving the connection structure between the existing crossarm and the insulator string. However, its complex design may increase manufacturing costs. Furthermore, since additional supports, upper clamps, and lower clamps are usually required, material and processing costs may be higher than with traditional crossarms. In addition, the complex mechanical structure may lead to higher maintenance costs in actual use. For example, replacing or repairing these components during high-altitude operations requires more resources, increasing the overall maintenance difficulty.

[0053] In some related technologies, automated spraying equipment can be used to improve corrosion protection efficiency; however, the complexity of the equipment can lead to increased operating and maintenance costs. For example, components such as the mixing motor, water bath device, and spray gun require regular maintenance or replacement, increasing the workload during long-term use. Furthermore, because the equipment needs to be used in high-altitude environments, its installation and operation may face greater difficulties and risks, further limiting the convenience of practical application.

[0054] In some related technologies, corrosion protection can be achieved by rust removal, applying anti-rust paint, wrapping with butyl rubber, and pouring airtight concrete. However, this method relies on surface treatment and encapsulation, and its anti-corrosion effect may decrease over long-term use due to material aging or incomplete construction. Furthermore, the repair process requires complex operations on the tower base (such as creating grooves and removing cement caps), which not only increases the difficulty of construction but may also pose potential risks to the structural strength.

[0055] The following explains some terms and concepts used in the embodiments of this application:

[0056] Transmission towers: are one of the basic pieces of equipment in overhead transmission lines, serving as supports for the transmission lines.

[0057] Vertical axis wind turbine: A vertical axis wind turbine (VAWT) is a device that converts wind energy into electrical energy through a vertically placed shaft and blades. Compared to horizontal axis wind turbines, it can receive wind from any direction and has the advantages of simple structure and high flexibility.

[0058] Energy storage devices: Energy storage devices are systems used to store electrical energy, typically including devices such as batteries and supercapacitors. Their function is to store excess electricity generated during wind power generation for use when needed.

[0059] Impressed current method: The impressed current method is a method of applying current to a target structure or material through an external power source. It is commonly used for corrosion protection (such as cathodic protection) or other electrochemical applications. For example, the impressed current method can be used in metal structures such as power transmission towers to slow down the corrosion rate of the metal.

[0060] Auxiliary anode: An auxiliary anode is a device in an electrochemical system used to provide additional current or assist the main anode in its operation. It is typically used in conjunction with a cathodic protection system to ensure that the protected structure (such as a transmission tower) receives sufficient cathodic current, thereby preventing corrosion.

[0061] Fixed pulley: A fixed pulley is a stationary mechanical device used to change the direction of force without saving effort. For example, in the construction or maintenance of power transmission lines, fixed pulleys can be used to lift and move heavy objects, such as conductors, insulators, or other equipment.

[0062] Potentiostat: By adjusting the output current and voltage, it ensures that the potential of the protected metal is stable within the range required for corrosion prevention, while avoiding over-protection or under-protection.

[0063] Reference electrode: Serves as a reference point, helping the potentiostat to accurately adjust the output current and ensure the potential stability of the protected structure.

[0064] Conduit: A protective outer shell or tube, typically used to wrap cables, wires or other components that require protection.

[0065] Conductor material: In a cathodic protection system, conductor material is used to connect the potentiostat, the sacrificial anode, and the protected structure to ensure stable current transmission.

[0066] Anti-corrosion coatings: Based on cathodic protection, anti-corrosion coatings further reduce the contact area between the metal and the environmental medium, thus extending the service life.

[0067] Grounding resistance: A measure of resistance in a grounding system, indicating the degree of obstruction to the flow of current from the grounding electrode to the earth. Low grounding resistance can effectively reduce voltage rise in equipment or structures, improving system safety.

[0068] Combination Figure 1 and Figure 2 This application first provides a power transmission tower 1 and its anti-corrosion system.

[0069] The foundation of transmission tower 1 is constructed by pouring concrete with foundation steel reinforcement 3. However, if the soil at the location of transmission tower 1 is too wet (e.g., near a river), the foundation steel reinforcement 3 is easily corroded. Figure 1As shown, firstly, a liftable vertical axis fan 2 is installed on the transmission tower 1. The vertical axis fan 2 can be directly installed on the top of the transmission tower 1, or it can be fixed to a platform inside the transmission tower 1 using a hoisting method. The advantage of this liftable vertical axis fan 2 is that in the face of extreme / severe weather (such as strong winds, heavy rain, or hail), the fan can be easily lowered to a safe position, avoiding equipment damage or even affecting the safety of the tower structure due to extreme weather conditions. Specifically, a platform 7 is designed and installed inside the tower. This platform 7 is a machined drilled iron plate, connected to the main body of the transmission tower 1 by welding or other fixing methods to provide sufficient load-bearing capacity and stability. A fixed pulley 6 and a motor 8 are further installed on the platform 7. The vertical axis fan is connected to the motor via a set of high-strength ropes 5. This design allows the motor to control the raising and lowering of the ropes by rotation, thereby driving the vertical axis fan to move up and down. This installation method is simple and easy to implement and can be directly applied to existing transmission towers. Furthermore, vertical axis fans can also be installed on top of the foundation steel bars 3 at the four bases of the transmission tower 1. This design not only makes full use of the tower's space resources but also allows for flexible adjustment of the number and layout of fans according to the power demand of different areas, thereby improving the overall efficiency and practicality of the system.

[0070] The alternating current (AC) generated by the vertical axis fan during operation is transmitted to rectifier 9 via connecting lines. The rectifier converts the AC to direct current (DC) to meet the input requirements of the energy storage device 11. The DC then enters buck converter 10, which reduces the voltage to a level suitable for storage and use by the energy storage device 11. This buck design effectively matches the operating parameters of the energy storage device, ensuring the safety and efficiency of energy storage. The energy storage device 11 can employ various technologies, such as lithium-ion batteries or supercapacitors, which are not specifically limited here.

[0071] like Figure 2As shown, the impressed current corrosion protection system for any one or more reinforcing bars 17 in the foundation reinforcing bars 3 of the transmission tower 1 may include a potentiostat 12, an anode junction box 13, a cathode junction box 14, a reference electrode 15, an auxiliary anode 16, reinforcing bars 17, and cables 18. The potentiostat 12 serves as the control core of the entire system, responsible for providing a stable DC power supply and automatically adjusting the output voltage and current based on the potential signal fed back from the reference electrode 15. The reference electrode 15 is buried in the soil near the reinforcing bars 17 and / or the transmission tower 1 to measure the potential near the reinforcing bars 17 and / or the transmission tower 1 in real time. The auxiliary anode 16 is a key component for current release, and its material typically includes graphite or other corrosion-resistant materials. Preferably, graphite can be used, buried at the lowest point of the reinforcing bar 17 and close to the reinforcing bar to ensure uniform current distribution. Scrap steel, aluminum, and zinc can also be used. The auxiliary anode is filled with coke as a filler (i.e., a coke anode bed), which can significantly reduce the actual material consumption rate, thereby extending the service life of the auxiliary anode. Cable 18 is an important channel for the transmission of electrical energy and signals in the system, including cables for auxiliary anodes and reference electrodes. Its main characteristics are as follows: it uses multi-strand copper core cable with good conductivity; the sheath should have insulation, aging resistance and corrosion resistance to adapt to complex environmental conditions.

[0072] The working principle of the impressed current method corrosion protection system for transmission tower 1 is as follows: The protective current output by the potentiostat 12 starts from the positive terminal, passes through the anode junction box 13, and is then shunt to the auxiliary anode. The current flows through the auxiliary anode to the reinforcing bar 17, and then returns to the negative terminal of the potentiostat after passing through the cathode junction box 14. The negative terminal of the potentiostat is connected to the top of the reinforcing bar 17 or the tower foot (a planing welding process can be used to ensure that the conductor of the negative terminal of the potentiostat is directly connected to the steel inside the tower, thus ignoring contact resistance), so that the protected area of ​​the tower is in a stable cathode potential state. The reference electrode 15 monitors the potential changes around the tower in real time and feeds the signal back to the potentiostat 12. The potentiostat adjusts the output voltage and / or output current of the anode according to the feedback signal to ensure that the protected area is always maintained within the optimal corrosion protection potential range.

[0073] In a first aspect, embodiments of this application provide a corrosion protection method for a power transmission tower 1. The reinforcing bars 17 connected to the power transmission tower 1 are electrically connected to an corrosion protection system. The corrosion protection system includes at least a potential output module, an auxiliary anode 16, and a potential monitoring module. The positive terminal of the potential output module is electrically connected to the reinforcing bar 17 via the auxiliary anode 16, and the negative terminal of the potential output module is electrically connected to the reinforcing bar 17 or the power transmission tower 1. The potential monitoring module is used to monitor the potential corresponding to the power transmission tower 1 to generate a potential signal. The positive terminal of the potential output module is used to output a preset protective current by default.

[0074] It is understandable that, since there is a connection between the transmission tower 1 and the reinforcing bar 17, the negative terminal of the potential output module, which is electrically connected to the transmission tower 1, can also be used to adjust the potential of the reinforcing bar 17 to achieve the anti-corrosion function.

[0075] See Figure 3 The diagram shows a flow chart of a corrosion prevention method for a transmission tower 1 provided in an embodiment of this application. The method includes steps S301-S304, as detailed below.

[0076] S301, acquire the potential signal and the anode information of the auxiliary anode 16.

[0077] S302, at least based on the potential signal and the anode information, construct model input data.

[0078] In some examples, the potential signal and the anode information can be directly combined to form the model input data. In this case, the optimal corrosion protection potential information can be determined based on the model input data using a neural network. This neural network can be a trained model capable of predicting using model input data containing the potential signal and the anode information as model input and the optimal corrosion protection potential information as model output. During training, sample model input data containing sample potential signals and sample anode information can be used as sample data (this sample data also carries the expected corresponding corrosion protection potential label, which represents the corresponding expected corrosion protection potential), and a general training algorithm (e.g., gradient descent) can be used to train the model so that the trained model possesses the aforementioned capabilities. It is easy to understand that the sample data in this embodiment can be experimental data obtained in advance through multiple corresponding experiments.

[0079] S303, based on the input data of the model, call the pre-trained neural network to determine the optimal anti-corrosion potential information.

[0080] In some examples, the model's input data can be directly fed into the neural network for prediction to determine the optimal corrosion protection potential information.

[0081] S304, based on the optimal anti-corrosion potential information, control the potential output module to adjust the current output by its positive terminal so that the adjusted current is the optimal protection current that matches the optimal anti-corrosion potential information.

[0082] In some examples, the optimal corrosion protection potential information can be used to indicate the magnitude of the current and / or voltage, and the optimal protection current can refer to a current whose magnitude and / or voltage are approximately equal to the magnitude of the current and / or voltage indicated by the optimal corrosion protection potential information.

[0083] In one alternative implementation, the anode information includes the number of anodes and / or anode lifetime of the auxiliary anode 16;

[0084] The number of anodes is determined by the ratio between the preset protection current and the anode design output current of the auxiliary anode 16, wherein the anode design output current is adapted to indicate the current output by the auxiliary anode 16 to the reinforcing bar 17 in accordance with the preset protection current;

[0085] The anode lifespan is determined by a preset safety factor, the net weight of the auxiliary anode 16 and the consumption rate of the auxiliary anode, and the average protection current of the protected metal structure, wherein the protected metal structure includes the reinforcing steel 17 and / or the transmission tower 1.

[0086] In some examples, the formula for calculating the number of anodes N may include:

[0087]

[0088] In the formula, I is the preset protection current, I a The anode design output current is used to assist anode 16.

[0089] In one optional implementation, the anode information includes the anode lifetime, which is determined by the ratio between the product of the preset safety factor, the auxiliary anode consumption rate, and the average protection current, and the net weight of the auxiliary anode.

[0090] In some examples, the formula for calculating the anode lifetime t may include:

[0091]

[0092] Where m is the net weight of the auxiliary anode, K is the preset safety factor, E is the auxiliary anode consumption rate, and I m The average protection current of the protected metal structure.

[0093] It should be noted that the average protection current required for the protected metal structure refers to the average current density that needs to be applied to prevent corrosion and ensure that the metal structure receives adequate cathodic protection.

[0094] In this embodiment, after selecting an auxiliary anode, the lifespan of the auxiliary anode can be calculated to regularly maintain the system and ensure the normal operation of the corrosion prevention system.

[0095] In one optional implementation, the step of determining the optimal corrosion protection potential information by calling a pre-trained neural network based on the model input data includes:

[0096] The input data of the model is normalized.

[0097] Feature extraction is performed on the normalized model input data to obtain the input features;

[0098] The input features are fed into the neural network to obtain the optimal anti-corrosion potential information output by the neural network.

[0099] In an optional implementation, the method further includes:

[0100] Obtain the soil resistivity of the soil where the reinforcing bar 17 is located and the environmental information of the environment where the transmission tower 1 is located, wherein the environmental information includes temperature and / or humidity;

[0101] The construction of model input data, based at least on the potential signal and the anode information, includes:

[0102] The model input data is constructed based on the soil resistivity, the environmental information, the potential signal, and the anode information.

[0103] In some cases, although a potentiostat can adjust the current output by the positive electrode by measuring the potential of the reference electrode, thus keeping the potential of the steel bar constant, in practical applications, environmental factors such as soil resistivity, humidity and / or temperature will change dynamically. The lifespan of the anode will decrease with the use time, and the number of anodes will also vary depending on the environment. This will result in the fixed potential range being unable to meet actual needs, causing insufficient corrosion protection.

[0104] Therefore, to address this situation, this embodiment further proposes an optimal potential prediction model based on a BP neural network, such as... Figure 4 As shown.

[0105] First, the input to the network input layer can be represented as:

[0106]

[0107] Where x(p) represents parameters such as temperature, humidity, soil resistivity, number of auxiliary anodes, and auxiliary anode lifetime. The hidden layer of a BP network can be represented as:

[0108]

[0109] in This represents the weight coefficients of the hidden layer. The activation function for the hidden layer is as follows:

[0110]

[0111] Next, the relationship between the network output layer and the optimal corrosion protection potential can be expressed as:

[0112]

[0113] Where y represents the optimal corrosion prevention potential. The activation function of the output layer is:

[0114] g(x) = x

[0115] The mean square error is expressed using the error exponential function:

[0116]

[0117] Where Y i and Let represent the network's expected output and actual output, respectively. Let w be the network weight vector. The network coefficients are updated using the Levenberg-Marquardt algorithm. Then, the formula for the vector containing the weights and values ​​can be expressed as:

[0118] w(k+1)=w(k)+Δw

[0119]

[0120] Where α is the learning rate, J is the Jacobian matrix, and I is the identity matrix. The structure of a neural network is as follows: Figure 4 As shown.

[0121] In some examples, the specific application process of this neural network is as follows:

[0122] (1) Data acquisition and preprocessing: Continuously monitor and record temperature, humidity, soil resistivity, number of anodes, anode life and real-time monitoring of potential changes on the surface of the tower reinforcement; normalize and extract features from the acquired data to ensure that the input data meets the requirements of the neural network model.

[0123] (2) Model training and optimization: The BP neural network model was trained using historical data (the known optimal anti-corrosion potential range and its corresponding environmental parameters, anode life and quantity).

[0124] (3) Online prediction and adjustment: In actual operation, the neural network model receives environmental parameters input from the sensors in real time and outputs the optimal anti-corrosion potential range under the current conditions. The system dynamically adjusts the output voltage and current of the potentiostat based on the prediction results to ensure that the steel bars are always in the optimal anti-corrosion state.

[0125] The innovation of this application lies in the installation of a vertical axis fan on the transmission tower 1 to provide power to the corrosion protection system. This is a novel power supply method for the corrosion protection system, which fully utilizes the height advantage of the transmission tower 1, while also allowing the electrical energy to be consumed locally. An optimal potential adaptive neural network prediction model is proposed for corrosion protection based on the foundation steel reinforcement of the transmission tower 1, enabling the optimal corrosion protection potential to dynamically adapt to anode life, anode quantity, and soil environment, etc.

[0126] Secondly, combining Figure 1 and Figure 2 This application provides an anti-corrosion system for a transmission tower 1, wherein the transmission tower 1 is connected to reinforcing bars 17, and the system includes:

[0127] Auxiliary anode 16;

[0128] A potential monitoring module is used to monitor the potential corresponding to the transmission tower 1 to generate a potential signal; and,

[0129] The potential output module has its positive terminal electrically connected to the reinforcing bar 17 via the auxiliary anode 16, and its negative terminal electrically connected to the reinforcing bar 17 or the transmission tower 1. The positive terminal of the potential output module is used to output a preset protection current by default. The potential output module is configured to perform the method described in any one of the first aspects above.

[0130] In one optional implementation, the potential output module includes a potentiostat 12;

[0131] And / or,

[0132] The potential monitoring module includes a reference electrode 15.

[0133] In one alternative implementation, the system further includes:

[0134] Anode junction box 13, the positive terminal of the potential output module is electrically connected to the auxiliary anode 16 via the anode junction box 13;

[0135] The anode junction box 13 is used to shunt the current from the positive terminal of the potential output module and output the shunt current to the auxiliary anode 16.

[0136] In one alternative implementation, the system further includes:

[0137] The cathode junction box 14 is used to electrically connect the negative terminal of the potential output module to the reinforcing bar 17 or the transmission tower 1.

[0138] The cathode junction box 14 is used to combine the current from the steel bar 17 or the transmission tower 1, and output the combined current to the negative terminal of the potential output module.

[0139] In one optional embodiment, the transmission tower 1 is equipped with a liftable vertical axis fan 2, and the system further includes:

[0140] Rectifier 9;

[0141] Step-down transformer 10; and,

[0142] The energy storage device 11 is electrically connected to the vertical axis fan 2 via the step-down transformer 10 and the rectifier 9 in sequence, and the discharge terminal of the energy storage device 11 is electrically connected to the input terminal of the potential output module.

[0143] In conjunction with the above-described embodiments of this application, the embodiments of this application can also achieve at least one of the following beneficial effects.

[0144] (1) Improve energy self-sufficiency: This application can utilize wind energy to provide power support for the corrosion protection system by installing vertical axis wind turbines and energy storage systems on transmission towers.

[0145] It should be understood that traditional anti-corrosion measures rely on external power sources or chemical materials, which not only increases operation and maintenance costs but may also lead to environmental pollution.

[0146] In view of this, this application achieves energy self-sufficiency through wind power generation, reducing dependence on the traditional power grid. Simultaneously, the introduction of an energy storage system ensures power supply stability, avoiding power outages caused by wind speed fluctuations. Therefore, this application improves the energy autonomy of transmission tower corrosion protection systems and reduces dependence on external power sources, thereby reducing power transmission losses and maintenance costs.

[0147] (2) Reduced maintenance workload: The vertical axis fan and energy storage system of this application can achieve automated operation, reducing the need for manual inspection and maintenance.

[0148] It should be understood that traditional anti-corrosion measures require regular inspection and maintenance, which increases operation and maintenance costs and manpower input.

[0149] In view of this, this application reduces reliance on manual intervention by automating the management of wind power generation and energy storage systems. This reduces maintenance workload, lowers operation and maintenance costs, and improves system reliability and security.

[0155] In view of this, this application ensures the stable operation of the corrosion protection system through continuous power support provided by wind power generation and energy storage systems. For example, corrosion protection technologies such as anodic protection require a stable current input, and this application can provide a reliable power supply guarantee. This extends the service life of the transmission tower and reduces safety hazards caused by facility aging.

[0156] (5) Improved economic efficiency: This application improves the economic efficiency of the entire system by reducing maintenance costs and extending facility life.

[0158] In view of this, this application significantly reduces overall operating costs by increasing energy self-sufficiency, reducing maintenance workload, and extending facility lifespan. Meanwhile, wind power, as a renewable energy source, has lower long-term operating costs. This improves the economic efficiency of the entire power transmission system and reduces economic losses caused by facility failures.
