[0002] Driven by globalization and technological progress, the safety and stability of the power system, as an important infrastructure of modern society, are of vital importance. As the core component of power transmission, high-voltage transmission lines are exposed to complex environments for a long time and are easily affected by natural factors (such as wind, rain, lightning, ice and snow, etc.) and external forces (such as construction interference, bird activities, etc.), leading to problems such as line wear, aging of insulation layers, and loosening of connectors. In order to ensure the safe operation of transmission lines, regular inspections and maintenance are essential. However, traditional manual inspection methods are inefficient, dangerous, and limited by terrain and weather conditions, making it difficult to meet the efficient operation and maintenance needs of modern power systems.

[0003] Traditional power transmission line inspections mainly rely on manual operations. Inspectors need to wear insulating equipment and use telescopes, infrared thermometers and other tools to conduct inspections on the ground or on high-altitude line towers. This method is not only inefficient and labor-intensive, but also poses safety risks such as high-altitude operations and electric shock. At the same time, due to the limitations of manual inspections, some line hazards may not be discovered in time, which in turn affects the overall safety and operating efficiency of the power transmission system.

[0004] With the development of robot technology, power line inspection robots have emerged. These robots can carry out real-time inspection of power lines by carrying sensors, cameras and other equipment, greatly improving the inspection efficiency and accuracy. However, there are still many technical challenges in the actual application of current power line inspection robots. For example, the battery capacity of the robot is limited, which limits its continuous working time and requires frequent shutdown for charging, affecting the inspection efficiency. At the same time, the complex line environment places higher requirements on the adaptability, mobility and safety of the robot.

[0005] The present invention provides a high-voltage transmission line inspection and protection device, which aims to solve the above technical problems. By adopting photovoltaic solar cell power supply and efficient air cooling design, the equipment can be ensured to operate stably for a long time. The robot body structure is compactly designed, and the hexagonal prism shell not only has excellent mechanical strength, but also can accommodate the line maintenance mechanism. Its drive system consists of three insulating rubber drive wheels, which can adapt to complex line environments and ensure smooth movement. The device integrates infrared sensors, cameras and lighting devices, can monitor the line status in real time, and supports day and night operations. The application of wireless communication modules realizes remote data transmission and monitoring, and further improves the convenience and automation level of inspection operations. The device is equipped with a unique bird-repelling device, which uses wind energy to drive the blades to rotate, generates sound and light interference, effectively drives away birds, and prevents them from interfering with the transmission line. The design of the insulating spring ensures safe contact of the equipment under high-voltage environment. The overall design structure is simple and easy to maintain, with the advantages of high efficiency, automation, low cost, etc., can adapt to various complex transmission line environments, and provides a practical solution for realizing intelligent, efficient, safe and environmentally friendly line inspection.

The photovoltaic solar panels (2) can absorb light and convert it into electrical energy, thereby providing a continuous source of power support for the device.

[0034] A line maintenance mechanism (4) is used to perform routine inspection and maintenance tasks on power transmission lines. The mechanism integrates multiple intelligent functions and can realize efficient and accurate line maintenance operations. A plurality of line maintenance probes (5) are installed at the front end of the line maintenance mechanism, and are arranged in a centrally symmetrical manner, wherein each line maintenance probe (5) is installed with a high-voltage cable maintenance device (15, 16).

[0035] According to the further optimization scheme, the line maintenance probe (5) can monitor the state of the power transmission line in real time through the sensing system (6), and automatically detect the wear, damage, looseness and other problems of the line. Once a problem is found, the line maintenance mechanism (4) will handle it through the high-voltage cable maintenance device (15, 16); the line maintenance probe (5) has an adaptive spring length function; the high-voltage cable maintenance device (15, 16) can include a hot melt maintenance device, a cable binding tool, an insulation repair material and an adaptive tool, etc., through precise control, to provide instant repair services for the line, thereby reducing manual intervention and improving maintenance efficiency; the maintenance probe and tools are made of high-strength insulation materials, and are equipped with intelligent temperature control and current monitoring systems to ensure that the maintenance device (15, 16) will not be disturbed by the current during maintenance, thereby improving the safety and effect of maintenance.

[0037] The sensing system (6) is one of the core intelligent modules of the high-voltage transmission line inspection and protection device, and integrates an infrared sensor (10), a high-definition camera (11) and a lighting device (12), providing the device with comprehensive line sensing and fault diagnosis functions; all components of the sensing system (6) are installed on the front of the main connecting column, and can obtain the status data of the transmission line in real time during the inspection process, and provide key support for subsequent maintenance, monitoring and data analysis.

[0038] To further optimize the solution, the sensing system (6) detects the temperature distribution and hot spots of the transmission line in real time through the integrated infrared sensor (10), identifies potential overheating, short circuit, fault or aging problems, and the infrared sensor (10) uses high-precision temperature detection technology to accurately measure the surface temperature changes of the line under different environmental conditions, and promptly detect abnormal high temperature phenomena, thereby providing accurate alarm signals for the DSP control unit (22).

[0039] Furthermore, a high-definition camera (11) is integrated into the perception system to provide high-quality image and video data, and can monitor the physical condition of the power transmission line in real time; the perception system (6) is integrated with a high-brightness lighting device (12), and the lighting device (12) can provide sufficient light in low-light or nighttime environments, and has the function of automatically adjusting brightness. In extreme weather conditions such as strong light, heavy rain, snow or fog, it can ensure the normal operation of the camera (11) and the sensor (10), and ensure 24-hour uninterrupted inspection work; the sensor (10) and the camera (11) of the perception system (6) are connected to the remote communication module to ensure that all collected data can be transmitted to the control unit and the remote monitoring center in real time. Through wireless communication protocols such as 4G / 5G networks, Wi-Fi or LoRa, the perception system (6) remotely transmits the collected temperature, image, video and other data to the monitoring platform, helping remote operators to analyze the data and make timely responses.

[0040] Furthermore, all modules of the perception system (6) are electrically connected to the control unit (22), and are uniformly coordinated and dispatched by the control unit (22). The control unit (22) receives feedback from each perception module in real time, processes and analyzes the data in combination with an internal algorithm, automatically generates an inspection report, and automatically adjusts the inspection strategy and equipment location as needed. The perception system (6) provides a real-time environmental monitoring function, thereby improving the autonomous decision-making and operation capabilities of the high-voltage transmission line inspection protection device.

[0041] The remote communication mechanism (22) has the ability to efficiently exchange data with the remote control center and peripheral devices, and supports wireless data transmission technologies such as 4G / 5G networks, Wi-Fi and other communication methods to ensure stable remote control and data transmission in different environments.

[0042] To further optimize the plan, during the inspection of high-voltage transmission lines, the robot device can feedback the inspection data to the monitoring center in real time, including line status, equipment operation status, environmental data, etc.; the monitoring center can analyze the transmitted data, discover potential problems in time, and make remote adjustments or issue instructions, thereby improving inspection efficiency and response speed.

[0043] To further optimize the solution, the remote communication mechanism (22) integrates encryption algorithms and anti-interference technology, which can ensure smooth communication even in a strong electromagnetic interference environment; the remote communication module has an intelligent alarm function. When the robot detects an abnormal situation (such as line damage, cable short circuit, equipment failure, etc.), it will automatically send an alarm to the monitoring center and upload on-site images and sensor data.

[0044] The cooling device (3) is composed of a double water-cooling spray device at the rear of the main connecting column (1). The water-cooling spray device is connected to the pipeline system through an internal micro water tank (17). It can effectively reduce the temperature when the equipment is running at high load to prevent overheating and equipment failure. The water-cooling spray device (17) adopts a high-efficiency atomizing nozzle, which can refine water molecules into tiny water mist, quickly evaporate and absorb heat, and reduce the ambient temperature.

[0045] To further optimize the solution, the design of the water-cooling spray device (17) has an intelligent temperature control function, which monitors the temperature changes inside the equipment in real time through an integrated temperature sensor (18). When the equipment temperature exceeds a preset safety range, the system automatically starts the water-cooling spray device to quickly cool down the equipment. When the temperature returns to a safe value, the water-cooling spray device automatically stops working, saving energy and avoiding unnecessary waste of water.

[0046] A bird-repelling device (8) is composed of a propeller-like device (7) of a wind power generation system (8). The propeller-like device (7) uses wind energy to drive blades to rotate, generating strong airflow and noise to interfere with the activities of birds, thereby effectively driving birds away from the power transmission line. The blades of the bird-repelling device are designed to have efficient airflow propulsion performance and can be adaptively adjusted according to wind speed and direction. They can work stably under different climatic conditions.

[0047] According to a further optimization scheme, the working principle of the bird-repelling device (8) relies on a wind-driven rotation mechanism. When the device is started, the propeller (7) blades of the wind power generation system (8) rotate rapidly, generating noise and disturbing airflow, thereby driving away approaching birds. In order to avoid unnecessary noise pollution to the environment, the noise control design of the bird-repelling device is also optimized so that the intensity of its sound waves and airflow will not have a negative impact on the surrounding ecosystem.

[0048] The power supply system (2, 8) includes two energy supply modes, photovoltaic (2) and wind power generation (8), to ensure that the high-voltage transmission line inspection and protection device can operate continuously and stably in various environments; the photovoltaic power supply system integrates three high-efficiency solar panels installed on the outside of the main connecting column, converts sunlight into electrical energy, and provides continuous energy support for the device.

[0049] According to a further optimized solution, the solar panel is connected to the internal high-energy battery (19), which can be efficiently charged during the day and provide sufficient power when there is no sunlight to ensure the normal operation of the device; the power supply system also includes a wind power generation module, which is located at the tail of the robot device and adopts a propeller-like design. It is equipped with 11 blades and can use the surrounding wind energy to drive the generator to generate electricity; the wind power generation system is electrically connected to the internal high-energy battery, which further enhances the stability of energy supply, especially in areas with strong winds, and can provide additional power support for the device to ensure that the equipment can continue to work in extreme environments.

[0050] Furthermore, the power supply mode combining photovoltaic and wind energy breaks the dependence on traditional cable power supply, can effectively utilize natural energy, and make the device have higher self-power supply capability and independence, which is particularly suitable for long-term inspection tasks in remote areas or complex environments. The system design is simple and efficient, and can intelligently adjust the power supply mode according to environmental changes, maximize energy utilization, extend the working time of equipment, and reduce maintenance costs.

[0051] The moving mechanism (20) is composed of three insulating rubber driving wheels (21) inside the main body connecting column. The driving wheels (21) are arranged in a centrally symmetrical manner to ensure that the device has excellent balance and stability in a complex power transmission line environment; each driving wheel (21) is made of high-strength insulating rubber material, which can effectively prevent current leakage and ensure safe operation under high-voltage power transmission lines.

[0052] Further optimizing the scheme, the design of the driving wheel (21) takes into account the special needs of high-voltage power lines, and especially enhances its ability to withstand high pressure, temperature and corrosion. Its surface is specially treated to adapt to extreme climate conditions, such as high temperature, low temperature, rain and snow, etc., to ensure that the device can still move smoothly in bad weather; the driving wheel (21) transmits power through an internal micro-drive motor, and the motor and the wheel are precisely adjusted and controlled through a precise gear system, which can flexibly adjust the driving force to ensure that the device can smoothly pass through complex line environments.

[0053] Furthermore, all driving wheels (21) are electrically connected to the control unit (22), and the mobile mechanism (20) can realize various actions such as moving forward, moving backward, turning, etc. through the instructions of the control unit; the control unit will intelligently optimize the route of the mobile mechanism (20) according to the perception system and remote monitoring data, automatically avoid obstacles, and select the best path for inspection. This intelligent system not only improves the accuracy of movement, but also enables the equipment to flexibly respond to various challenges in the complex power line architecture, greatly improving the efficiency and safety of inspection operations; the mobile mechanism is also equipped with an adaptive adjustment function, which can automatically adjust the driving force and speed according to the different forms and environmental conditions of the transmission line, ensuring that the device always maintains the best state when performing tasks.

[0054] Directions:

[0055] When the robot device starts working, the high energy density battery module (19) first performs a self-check procedure to confirm the remaining power and power supply mode status. If the battery power is lower than the preset threshold (usually set to 20% of the total capacity), the system will preferentially activate the photovoltaic power supply system (2), absorb light energy through the three high-efficiency solar panels (2) on the outside of the main connecting column, and monitor the light intensity in real time. In insufficient light or at night, the system automatically switches to the wind power generation mode (8), using the 11 blades of the tail propeller device (7) to capture wind energy and drive the internal wind power generation module to charge the battery. The dual-mode power supply system realizes intelligent energy scheduling through the DSP control unit (22) to ensure the continuous operation of the equipment in extreme environments.

[0056] After starting, the control unit (22) loads a preset inspection route or receives a task instruction issued by the remote control center. The three insulating rubber drive wheels (21) of the mobile mechanism are powered by a micro drive motor (19). The surface of the drive wheel (21) adopts an anti-slip texture design, and the control unit (22) dynamically adjusts the torque output of the drive wheel based on the real-time feedback of the line friction coefficient and displacement data by the speed sensor and the position sensor to ensure that the transmission line can still be climbed smoothly under ice, snow or strong wind conditions; the high-voltage transmission line passes through the inspection robot device as a whole through the line entry.

[0057] During the journey, the sensing system performs a multi-spectral scan of the line through the front infrared camera (10) and the high-definition camera (11). The infrared sensor collects conductor temperature data at a rate of 30 frames per second. When it detects that the local temperature rise exceeds the safety threshold (such as 15°C higher than the ambient temperature), the system immediately marks the fault point and triggers the maintenance mechanism. The line maintenance probe (5) extends axially along the air source shock-absorbing spring (15), and the hot melt maintenance device is used to perform insulation repair on the damaged part of the conductor.

[0058] At the same time, the lighting device (12) automatically adjusts the fill light angle according to the ambient light intensity, and cooperates with the camera to complete nighttime high-definition imaging. When the temperature inside the device rises to 45°C due to continuous operation, the dual water-cooling spray system of the cooling device is activated, and the micro-water tank sprays cooling water mist through the atomizing nozzle, combined with the air duct design inside the main connecting column (1) to achieve rapid heat dissipation, and automatically shuts down after the temperature drops to save water resources.

[0059] The bird-repelling device (8) works in coordination with the wind power generation system (8): the low-frequency sound waves generated by the rotation of the propeller blades (7) are amplified through the resonance cavity to form a bioacoustic interference signal that birds are sensitive to, and the light and shadow flickering effect generated by the rotation is coordinated. The intensity of the bird-repelling device is dynamically adjusted through the intelligent sensing system.

[0060] Inspection data is transmitted back to the control center in real time through the wireless communication module (22), which supports 4G / 5G network redundant transmission and complements LoRa narrowband communication. Encrypted channels are enabled in areas with strong electromagnetic interference to ensure data security. Routine maintenance only requires cleaning the drive wheel groove and checking the self-cleaning system filter every quarter.

[0061] Through the deep integration of multimodal energy supply, adaptive mobility and intelligent closed-loop operation and maintenance, this device realizes unmanned, all-weather operation of high-voltage transmission line inspection, significantly improving the efficiency and safety of high-voltage transmission line system operation and maintenance.

The high-voltage transmission line inspection and protection device according to claim 1 is characterized in that: The sensing system (6) integrates an infrared sensor (10), a high-definition camera (11) and a lighting device (12), is installed at the front of the main connecting column (1), and supports multi-spectral scanning and night imaging.

5. The high-voltage transmission line inspection and protection device according to claim 1 is characterized in that: The bird-repelling device (8) shares a propeller blade (7) with the wind power generation module (8). The bird-repelling device generates an acoustic-optical composite bird-repelling signal through the rotation of the propeller blade (7). The blade rotation speed is associated with the bird-repelling intensity. When the infrared sensor (10) detects that a bird is approaching, the rotation speed is increased and the strobe lighting device (12) is synchronously triggered.
