Description

Technical Field

[0001] This invention belongs to the field of insulator testing technology, and more specifically, relates to a drone-mounted uninterruptible zero-value insulator testing device for power transmission lines. Background Technology

[0002] Insulators installed on power transmission lines are subjected to electromechanical loads, sun and rain, and temperature changes over a long period of time during operation. This can lead to faults such as reduced insulation resistance, insulation cracking, or even breakdown, posing a potential threat to the reliability of power supply. Therefore, the detection of the insulation condition of insulators is of great significance. Over time, the insulation or mechanical properties of insulators operating in overhead lines will deteriorate, resulting in zero-value or low-value insulators. This phenomenon is called insulator deterioration. In high-voltage transmission systems, if there are zero-value or low-value insulators in an insulator string, it is equivalent to a part of the insulation of the insulator string being short-circuited. The overall creepage distance is also reduced accordingly. The probability of flashover in an insulator string containing deteriorated insulators is greatly increased. When a flashover occurs, the arc may pass through the inside of the zero-value insulator, and its steel cap often cracks or detaches, resulting in serious accidents such as the string falling off and the conductor falling to the ground. Currently, drone-mounted uninterruptible zero-value insulator testing devices for power transmission lines have been found to have at least the following technical problems: 1. In the inspection of zero-value insulators of transmission lines, drones carrying inspection equipment need to hover or move at low speed in strong airflow environments at high altitudes. Their attitude stability is significantly affected by wind speed and airflow disturbance. In actual operation, even experienced drone pilots cannot completely avoid accidental contact between the inspection components and insulators caused by sudden gusts of wind, drone attitude fine-tuning delays, or positioning errors (especially in complex terrain or dense line areas), which can lead to damage. 2. Insulators are exposed to the outdoor environment for a long time, and various pollutants will inevitably accumulate on their surface. The type, composition and accumulation degree of these pollutants will vary significantly depending on the environment, which will have a direct and complex impact on the accuracy of zero-value insulator detection based on the electric field measurement principle. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a drone-mounted uninterruptible zero-value insulator testing device for power transmission lines. This device solves the problems that existing equipment is prone to damage to insulators due to contact with wind speed and airflow disturbances, and that insulators exposed for a long time are prone to accumulating contaminants, which affects the testing process.

[0004] A drone-mounted uninterruptible zero-value insulator detection device for power transmission lines includes a mounting frame, which is bolted to the drone. A three-axis gimbal is fixedly mounted on the lower end of the mounting frame. The gimbal uses a built-in motor to compensate for the drone's pitch, roll, and yaw jitter in real time, reducing interference from distance changes on electric field measurements. A stable relative distance ensures the accuracy and reliability of the electric field measurement data. A detection frame is fixedly mounted on the lower end of the three-axis gimbal. Two arc-shaped mounting strips are symmetrically fixedly mounted on the lower inner wall of the detection frame. Electric field sensors for insulator detection are fixedly mounted on both arc-shaped mounting strips. Each electric field sensor is equipped with an anti-accidental contact mechanism. Each of the electric field sensors has a limit block fixedly installed at equal intervals. Both electric field sensors have equally spaced connecting slots on their sidewalls. Each electric field sensor contains a lidar and a binocular vision camera. The lidar is used to capture the real-time position of rigid structures such as the insulator cap and skirts. The binocular vision camera locates the edge of the insulator through image recognition and helps filter background interference. A flexible probe is fixedly installed at the center of each electric field sensor, effectively preventing damage caused by contact between the flexible probe and the insulator. This not only reduces equipment maintenance and replacement costs and extends the lifespan of the device, but also ensures the continuity of detection work and avoids detection interruptions due to equipment damage.

[0005] Preferably, each of the two electric field sensors is threaded with a first threaded ring, and a sliding column is slidably installed inside each of the two first threaded rings. A nitrile rubber ring is fixedly installed on the end of each of the three sliding columns away from the first threaded ring. A spring is sleeved on each of the three sliding columns, and the two ends of the three springs are fixedly connected to the first threaded ring and the nitrile rubber ring, respectively. A connecting frame is fixedly installed on the opposite ends of each of the two nitrile rubber rings, and a fan is fixedly installed on the lower end of each of the two connecting frames. This reduces the maintenance and replacement costs of the equipment, extends the service life of the device, and ensures the continuity of the detection work.

[0006] Preferably, a cleaning ring is slidably sleeved on each of the two flexible probes, and a second threaded ring is fixedly installed on each of the two cleaning rings. The two second threaded rings are respectively threaded into the inner wall of the two electric field sensors. During the installation process, the surface of the flexible probe can be cleaned, ensuring the cleanliness of the surface of the flexible probe and providing a reliable guarantee for subsequent detection work.

[0007] Preferably, each of the two fans has an air duct installed at its outlet end, a water trough is formed on the side wall of each of the two air ducts, an air hole is formed at the end of each of the two air ducts, an annular groove is formed in the inner wall of each of the two air ducts, an air plate is rotatably installed inside each of the two annular grooves, air guide blocks are fixedly installed at equal intervals on the side wall of each of the two air plates, an atomizing plate is fixedly installed inside each of the two air ducts, a water storage tank is fixedly installed on the side wall of each of the two air ducts, the two water storage tanks are respectively connected to the two air ducts through the two water troughs, an internal threaded ring is fixedly installed inside each of the two air plates, and a central air pipe is threadedly installed inside each of the two internal threaded rings. The central air pipe is slidably installed in the air duct, which reduces the detection error caused by impurities covering the air, and enables the detection equipment to obtain the relevant data of the insulator more accurately, thereby ensuring the accuracy and reliability of the detection results and providing a stronger basis for determining whether the insulator is zero.

[0008] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by incorporating a three-axis gimbal, a first threaded ring, a sliding column, a nitrile rubber ring, a spring, and a flexible probe, the equipment can be kept in a horizontal and stable state, creating a stable environment for the testing operation. This avoids interference caused by factors such as device tilting, ensuring the smooth progress of the testing steps and improving the controllability of the testing process. The equipment can test zero-value insulators without power interruption. When the flexible probe accidentally comes into contact with the insulator, the nitrile rubber ring will be subjected to compressive force. Under the action of compressive force, the sliding column will slide inside the first threaded ring, and the spring will be compressed accordingly. The nitrile rubber ring protects the flexible probe inside, effectively preventing damage caused by contact between the flexible probe and the insulator. This not only reduces the maintenance and replacement costs of the equipment and extends the service life of the device, but also ensures the continuity of the testing work and avoids testing interruptions due to equipment damage. In this invention, compared with simple gas cleaning, this gas-liquid combination method greatly enhances the thoroughness of the cleaning effect, provides a cleaner environment for subsequent testing, avoids the adhesion of impurities after long-term use of insulators, and prevents these impurities from interfering with the testing process such as electric field measurement. It also reduces the detection error caused by impurity coverage, enabling the testing equipment to obtain relevant data of the insulator more accurately, thereby ensuring the accuracy and reliability of the test results and providing a stronger basis for determining whether the insulator is zero. In this invention, an electric field sensor, a flexible probe, a connecting frame, a fan, an air duct, and a central air duct are provided. When the air duct is moved in the direction of the electric field sensor, it will drive the connecting frame and the fan to move accordingly. At this time, the fan and the central air duct will also move accordingly, while the position of the flexible probe remains unchanged. During this process, starting the fan can blow and clean the surface of the flexible probe through the central air duct, which can ensure that the flexible probe always maintains a good working condition, ensures the stable performance of its detection, improves detection efficiency, and ensures the continuity and timeliness of the detection work of zero-value insulators of transmission lines. In this invention, by providing a limiting block and a first threaded ring, installation is completed when the first threaded ring rotates to contact the limiting block, and disassembly is completed otherwise. The entire assembly and disassembly process does not require too much time and effort, which greatly improves the efficiency of equipment assembly and disassembly. Especially in outdoor operations or emergency maintenance scenarios, it can effectively save operation time. In this invention, a central air tube and an internally threaded ring are provided. The central air tube can be rotated inside the internally threaded ring. Because the two are threadedly connected, the extension length can be adjusted by rotating the central air tube, thereby adjusting the distance between the central air tube and the insulator. When the distance is closer, the airflow is more concentrated and the blowing force is greater, which is suitable for removing stubborn stains. When the distance is farther, the airflow spreads more widely and can cover a larger inspection area, meeting the needs of comprehensive cleaning. The operator can precisely adjust the position of the central air tube according to the degree of contamination on the insulator surface and the cleaning requirements. This avoids damage to the insulator surface due to excessive blowing force caused by the distance being too close, and also prevents incomplete cleaning due to the distance being too far. This improves the versatility of the device in different inspection scenarios and reduces the need to replace equipment due to differences in cleaning requirements. Attached Figure Description

[0011] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0012] Please see Figures 1-10 This invention provides a drone-mounted uninterruptible zero-value insulator detection device for power transmission lines, including a mounting frame 1. The mounting frame 1 is bolted to the drone. A three-axis gimbal 2 is fixedly mounted on the lower end of the mounting frame 1. The three-axis gimbal 2 can compensate for the pitch, roll, and yaw jitter of the drone in real time through its built-in motor, ensuring that the relative distance fluctuation between the flexible probe 14 inside the electric field sensor 5 and the insulator is controlled within ±0.1m. This reduces the interference of distance changes on electric field measurement, and the stable relative distance ensures the accuracy and reliability of the electric field measurement data, providing a basis for the accurate detection of zero-value insulators. With a solid data foundation, the misjudgment or omission caused by measurement error is reduced. The lower end of the three-axis gimbal 2 is fixedly installed with a detection frame 3. The lower end of the inner wall of the detection frame 3 is symmetrically fixedly installed with arc-shaped mounting strips 4. Electric field sensors 5 for detecting insulators are fixedly installed on both arc-shaped mounting strips 4. Anti-misoperation mechanism is sleeved on both electric field sensors 5. Limit blocks 6 are fixedly installed at equal intervals on both electric field sensors 5. Communicating slots 7 are opened at equal intervals on the side walls of both electric field sensors 5. LiDAR 12 and binocular vision camera 13 are set inside both electric field sensors 5. The lidar 12 (measurement range 0.3~3m, accuracy ±1cm) outputs distance data 300 times per second to capture the real-time position of rigid structures such as insulator caps and skirts; The binocular vision camera 13 (60fps) locates the edge of the insulator through image recognition, and helps filter background interference (such as towers and conductors). The module has a built-in edge computing chip that fuses laser ranging data with visual contour data to generate a "safe distance threshold" (dynamically set according to the length of the insulator string, usually ≥0.5m). When the measured distance is less than the threshold, the controller immediately sends a "hover + fine-tuning backward" command to the UAV flight control system (response delay ≤0.1s).

[0013] Flexible probes 14 are fixedly installed at the center of each of the two electric field sensors 5. First threaded rings 8 are threaded onto each of the two electric field sensors 5. Sliding pins 9 are slidably installed through each of the two first threaded rings 8. Acrylonitrile rubber rings 10 are fixedly installed on the ends of the three sliding pins 9 away from the first threaded rings 8. Springs 11 are fitted onto each of the three sliding pins 9, and both ends of the three springs 11 are fixedly connected to the first threaded rings 8 and the nitrile rubber rings 10, respectively. Connecting brackets 17 are fixedly installed on the opposite ends of the two nitrile rubber rings 10. Fans 18 are fixedly installed at the lower ends of the two connecting brackets 17 to prevent damage to the detection process caused by factors such as device tilting. The interference caused by the flexible probe 14 is minimized, ensuring the smooth progress of the detection steps and improving the controllability of the detection process. When the flexible probe 14 accidentally comes into contact with the insulator, the nitrile rubber ring 10 will be subjected to compressive force. Under the action of compressive force, the sliding column 9 will slide inside the first threaded ring 8, and the spring 11 will be compressed accordingly. The flexible probe 14 is protected inside by the nitrile rubber ring 10, which can effectively avoid the damage caused by the contact between the flexible probe 14 and the insulator. This not only reduces the maintenance and replacement costs of the equipment and extends the service life of the device, but also ensures the continuity of the detection work and avoids the interruption of detection due to equipment damage. Cleaning rings 15 are slidably fitted on both flexible probes 14, and second threaded rings 16 are fixedly installed on both cleaning rings 15. The two second threaded rings 16 are respectively threaded into the inner walls of the two electric field sensors 5. When in use, the second threaded rings 16 can be threaded into the electric field sensors 5. At this time, the cleaning rings 15 will contact the flexible probes 14 and be fitted onto the flexible probes 14. Thus, the surface of the flexible probes 14 can be cleaned during the installation process, which can ensure the cleanliness of the surface of the flexible probes 14 and provide a reliable guarantee for subsequent detection work. Each of the two fans 18 has an air duct 19 installed at its outlet. Each air duct 19 has a water trough 20 on its side wall and an air hole 21 at its end. Each air duct 19 has an annular groove 22 on its inner wall, and an air disc 24 is rotatably installed inside each annular groove 22. Air guide blocks 25 are fixedly installed at equal intervals on the side walls of each air disc 24. Each air duct 19 has an atomizing disc 26 fixedly installed inside its interior. Each air duct 19 has a water storage tank 27 fixedly installed on its side wall. The two water storage tanks 27 are connected to the two fans 18 respectively via the two water troughs 20. The air ducts 19 are connected, and each of the two air plates 24 has an internally threaded ring 28 fixedly installed inside. Each of the two internally threaded rings 28 has a central air pipe 23 threaded inside. The central air pipe 23 is slidably installed in the air duct 19, which avoids the adhesion of impurities to the insulator after long-term use. These impurities interfere with the detection process such as electric field measurement, reduce the detection error caused by impurity coverage, and enable the detection equipment to obtain relevant data of the insulator more accurately. This ensures the accuracy and reliability of the detection results and provides a stronger basis for judging whether the insulator is zero.

[0014] Working principle: The first step involves mounting the mounting frame 1 and the drone base plate together using bolts. Then, the drone takes off and lifts the equipment for flight. During this time, the three-axis gimbal 2 uses its built-in motor to compensate for the drone's pitch, roll, and yaw jitter in real time, ensuring that the relative distance fluctuation between the flexible probe 14 inside the electric field sensor 5 and the insulator is controlled within ±0.1m. This reduces the interference of distance changes on electric field measurements. A stable relative distance ensures the accuracy and reliability of the electric field measurement data, providing a solid data foundation for the accurate detection of zero-value insulators and reducing misjudgments or omissions caused by measurement errors. The detection frame 3 remains horizontal at all times. When the detection frame 3 moves above the insulator, the drone is controlled to lower the detection frame 3, positioning the insulator inside the detection frame 3. At this point, the inspection begins. During testing, the drone is kept in a hovering state. The horizontal and stable state creates a stable environment for the testing operation, avoiding interference caused by factors such as device tilt, ensuring the smooth progress of the testing steps, and improving the controllability of the testing process. When the flexible probe 14 accidentally comes into contact with the insulator, the nitrile rubber ring 10 will be subjected to compressive force. Under the action of compressive force, the sliding column 9 will slide inside the first threaded ring 8. At this time, the spring 11 will be compressed accordingly. The nitrile rubber ring 10 protects the flexible probe 14 inside, which can effectively avoid damage caused by the flexible probe 14 coming into contact with the insulator. This not only reduces the maintenance and replacement costs of the equipment and extends the service life of the device, but also ensures the continuity of the testing work and avoids testing interruptions caused by equipment damage. The second step involves the drone carrying the detection frame 3 positioned at the detection location. At this point, the two fans 18 can be activated via an external controller. The fans 18 blow air through the duct 19 onto the insulator. The duct 19 then blows air through the vents 21 onto the central air pipe 23 and the air plate 24. The central air pipe 23 blows air onto the insulator. When the air blows onto the air plate 24, the wind force actuates the guide block 25, causing the air plate 24 to rotate within the annular groove 22. Simultaneously, the vents on the air plate 24 expel air. At the same time, water from the water tank 27 flows through the water trough 20 between the duct 19 and the central air pipe 23, and is then carried out by the airflow through the vents 21. During this process, the water mixes with the mist... The vapor is atomized upon contact with the vaporizing disc 26 and then sprayed through the air disc 24 onto the insulator testing area. Combined with the concentrated spraying from the central air pipe 23, the insulator testing area is cleaned. The water vapor adheres more evenly to the insulator surface, effectively removing dust, stains, and other impurities that affect testing. Compared to simple gas cleaning, this gas-liquid combination method greatly enhances the thoroughness of the cleaning effect, providing a cleaner environment for subsequent testing. It avoids the adhesion of impurities to the insulator after long-term use, which can interfere with the testing process such as electric field measurement. It also reduces testing errors caused by impurity coverage, enabling the testing equipment to obtain relevant data of the insulator more accurately. This ensures the accuracy and reliability of the test results and provides a stronger basis for determining whether the insulator is at zero value. Thirdly, when the air duct 19 moves in the direction of the electric field sensor 5, it will drive the connecting frame 17 and the fan 18 to move accordingly. At this time, the fan 18 and the central air pipe 23 will also move accordingly, while the position of the flexible probe 14 remains unchanged. During this process, the fan 18 can be started to blow and clean the surface of the flexible probe 14 through the central air pipe 23, which can ensure that the flexible probe 14 always maintains a good working condition, ensures the stable performance of its detection, improves detection efficiency, and ensures the continuity and timeliness of the detection work of zero-value insulators of transmission lines. The fourth step is to install the first threaded ring 8 onto the electric field sensor 5. The installation is completed when the first threaded ring 8 rotates to contact the limit block 6, and disassembly is completed otherwise. The entire installation and disassembly process does not require too much time and effort, which greatly improves the efficiency of equipment assembly and disassembly. Especially in outdoor operations or emergency maintenance scenarios, it can effectively save operation time. Fifth, when it is necessary to adjust the blowing force and range of the central air tube 23, the central air tube 23 can be rotated inside the internal threaded ring 28. Since the two are threadedly connected, the extension length can be adjusted by rotating the central air tube 23, thereby adjusting the distance between the central air tube 23 and the insulator. When the distance is closer, the airflow is more concentrated and the blowing force is greater, which is suitable for removing more stubborn stains. When the distance is farther, the airflow spreads more widely and can cover a larger inspection area, meeting the needs of comprehensive cleaning. The staff can precisely adjust the position of the central air tube 23 according to the degree of contamination on the insulator surface and the cleaning needs. This can avoid damage to the insulator surface due to excessive blowing force caused by the distance being too close, and can also prevent incomplete cleaning due to the distance being too far. This improves the versatility of the device in different inspection scenarios and reduces the need to replace equipment due to differences in cleaning needs.
