To address these issues, this invention proposes an intelligent drone mounting device for high-voltage power line inspection. Summary of the Invention

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-8As shown, an intelligent drone mounting device for high-voltage power line inspection includes a mounting plate 1. Two limiting frames 2 are fixedly connected to both sides of the mounting plate 1. Bolts 3 are provided through the side walls of the limiting frames 2, and nuts are provided on the bolts 3. The bolts 3 can quickly form a stable connection with the drone landing gear. The installation and disassembly are convenient and efficient. At the same time, it can ensure the tightness of the connection between the mounting device and the drone, avoid the connection from loosening due to vibration during the inspection, and significantly improve the safety and reliability of the device.

[0030] Mounting plate 1 is equipped with a detection mechanism for detecting line problems. The detection mechanism includes a rotating shaft 4 rotatably connected to mounting plate 1. A placement plate 5 is fixedly connected to the upper end of the rotating shaft 4. An infrared thermal imager 8 and a laser rangefinder 11 are mounted on the upper end of the placement plate 5. A first motor 6, a controller 7, and a battery box 18 are fixedly connected to the upper end of mounting plate 1. The infrared thermal imager 8 is a FLIRT1020 model, which has a wide temperature measurement range and high thermal resolution, and can accurately capture subtle temperature differences in the equipment. The laser rangefinder 11 is a Leica DISTOD510 model, with a measurement accuracy of ±1 mm and a range covering 0.05-200 meters, which can meet the distance measurement requirements of line inspection. The waterproof design of the first motor 6, controller 7, and battery box 18 allows them to adapt to complex environments such as rain and high humidity, effectively protecting core components from water vapor corrosion and improving the environmental adaptability and service life of the device.

[0031] The first motor 6 output shaft and the rotating shaft 4 side wall are respectively fixedly connected to the first gear and the second gear (it is worth noting that the rotation range of the placement disk 5 does not exceed 360 degrees, and the output shaft of the first motor 6 can rotate in both directions). The lower end of the mounting plate 1 is provided with two main mounting parts 19. The two side walls of the main mounting parts 19 are provided with first screws. The second motor 21 is installed on the side wall of one of the main mounting parts 19. The output shaft of the second motor 21 is fixedly connected to the main rotating rod 20. The main rotating rod 20 can rotate within the two main mounting parts 19. When the front end of the main rotating rod 20 (the end away from the second motor 21) rotates into the main mounting part 19 where the second motor 21 is located, the rope on the main rotating rod 20 will automatically fall off. The automatic rope release design of the main rotating rod 20 simplifies the operation process of placing the load or retrieving the rope, and the operation can be completed without manual intervention, thus improving the inspection efficiency.

[0032] The upper part of the placement tray 5 is equipped with a monitoring mechanism for monitoring environmental conditions. The monitoring mechanism includes a mounting plate 13 fixedly connected to the upper part of the placement tray 5. A barometric pressure sensor 10 and a humidity sensor 14 are installed on the upper part of the mounting plate 13. The barometric pressure sensor 10 is a BMP280 model, which has high precision and low power consumption characteristics, and the measurement range covers 300-1100hPa. The humidity sensor 14 is a SHT30 model, which has fast response speed and humidity measurement accuracy of ±2%RH. The two are integrated and installed on the mounting plate 13. The layout is compact and reasonable, which can quickly collect barometric pressure and humidity data of the inspection area, provide basic data support for subsequent operation analysis, and improve the integrity of inspection data.

[0033] In this invention, a wind speed sensor 12 and a temperature sensor 16 are installed on the upper end of the mounting plate 13, and an ultrasonic partial discharge detector 9 and an electric field strength detector 15 are installed on the upper end of the placement plate 5. The wind speed sensor 12 is a model FS4003, which can simultaneously detect wind speed and wind direction, with high measurement accuracy and strong anti-interference ability; the temperature sensor 16 is a model DS18B20, with a wide temperature measurement range, and can work stably in the range of -55℃ to +125℃, with an accuracy of ±0.5℃; the ultrasonic partial discharge detector 9 is a model PDCheckUHF, with high detection sensitivity, and can capture weak partial discharge signals; the electric field strength detector 15 is a model EFA-300, which can accurately measure the electric field distribution around high-voltage lines, with a wide measurement range. The integrated design of these devices enables the device to have both environmental parameter monitoring and line fault detection capabilities, eliminating the need to carry multiple additional devices, simplifying the configuration of inspection equipment, and improving the convenience of operation.

[0034] In this invention, the upper end of the placement tray 5 is provided with multiple limiting strips 17, and the two side walls of the limiting strips 17 are provided with second screws. The limiting strips 17 can be used to firmly fix the infrared thermal imager 8, ultrasonic partial discharge detector 9 and other equipment through the second screws to prevent the equipment from shifting during flight.

[0035] In this invention, the lower end of the mounting plate 1 is provided with a vertical plate 24, and an electric push rod 26 is fixedly connected to the side wall of the vertical plate 24. A movable frame 25 is fixedly connected to the output end of the electric push rod 26. An electric gripper 23 is installed on the inner wall of the movable frame 25. The vertical plate 24 is fixedly connected to two slide rails 22. The insulating pads of the two claws of the electric gripper 23 are made of high-strength insulating material, which can effectively isolate the high voltage electric field, avoid the risk of electric shock when gripping foreign objects, and ensure operational safety.

[0036] In this invention, two slide rails 22 are fixedly connected to the lower end of the mounting plate 1, and limit plates are fixedly connected to both side walls of the movable frame 25. The limit plates are slidably connected to the adjacent slide rails 22. Multiple fourth screws are provided at the lower end of the slide rails 22, making the slide rails 22 detachable. The sliding cooperation design between the limit plates and the slide rails 22 can accurately constrain the movement trajectory of the movable frame 25, ensuring that the electric gripper 23 can extend and retract smoothly along the preset direction, avoiding deviation that could lead to gripping failure. The detachable design of the slide rails 22 with the fourth screws facilitates future maintenance and replacement. At the same time, the installation position can be adjusted according to the operation requirements, improving the ease of maintenance and flexibility of use of the device.

[0037] In this invention, the lower end of the mounting plate 1 is provided with multiple auxiliary mounting parts, two of which are equipped with a third motor on their side walls. The output shaft of the third motor is fixedly connected to an auxiliary rotating rod. Both sides of the lower end of the auxiliary mounting parts are provided with third screws, which allows the multiple auxiliary mounting parts to be disassembled and assembled. A secondary rope can be hung on the auxiliary rotating rod between two auxiliary mounting parts on the same side, so that heavy objects can also be hung on both sides of the drone. It is worth noting that the weight of the heavy objects on both sides needs to be equal or hung on both sides of the center of the tubular object, thus enriching the functions of the device.

[0038] In this invention, the upper end of the mounting plate 1 is provided with multiple through slots, which effectively reduces the overall weight of the device, reduces the flight load of the UAV, and improves the flight endurance while ensuring structural strength. The mounting plate 1 is made of steel plate, which can provide a stable mounting carrier for each component, resist the impact of external forces such as airflow impact and minor collisions that may be encountered during the inspection process, and extend the service life of the device.

[0039] In the initial state, controller 7 is connected to the UAV control system.

[0040] In use, the infrared thermal imager 8 and laser rangefinder 11 mounted on the mounting plate 1 can rotate the rotating shaft 4 via the first motor 6 when a specific direction needs to be detected, thereby rotating the placement plate 5 in front of the drone. The infrared thermal imager 8 can detect the temperature distribution of equipment such as wire joints, insulators, and transformers, quickly identifying potential overheating hazards, such as poor contact at joints or aging and overheating of insulators, and providing timely warnings of equipment failure or fire risks. The laser rangefinder 11 can measure data such as the distance between towers and the distance between equipment and lines, assisting in verifying line parameters, accurately determining the safe distance between equipment and lines, and avoiding safety hazards.

[0041] The mounting plate 13 is equipped with a barometric pressure sensor 10, a humidity sensor 14, a wind speed sensor 12, and a temperature sensor 16, which can monitor meteorological data such as wind speed, wind direction, temperature, humidity, and air pressure in the inspection area in real time. This data can provide a basis for judging the safety of inspection operations, such as whether it is suitable for flight on windy days or whether the operation time needs to be adjusted in high temperature and high humidity environments. At the same time, it provides support for equipment status analysis, helps to assess the impact of high temperature and high humidity, low air pressure and other environments on power equipment, and improves the scientific nature of inspection decisions.

[0042] The placement tray 5 is also equipped with an ultrasonic partial discharge detector 9 and an electric field strength detector 15. The ultrasonic partial discharge detector 9 can detect partial discharge phenomena in high-voltage equipment such as insulators and switchgear, and capture weak discharge signals caused by insulation defects. The electric field strength detector 15 can detect the electric field distribution around the high-voltage line and accurately determine the abnormal electric field area. The two together can help analyze the insulation condition of the line, provide early warning of insulation faults, and effectively prevent insulation breakdown accidents.

[0043] In addition, the electric gripper 23, electric push rod 26, and moving frame 25 installed at the lower end of the mounting plate 1 can be used to control the presence of foreign objects such as kites, plastic sheets, and tree branches on the line. When these foreign objects are detected, the controller 7 issues a command, and the electric push rod 26 drives the moving frame 25 to slide along the slide rail 22, causing the electric gripper 23 to extend to the location of the foreign object. After the electric gripper 23 closes and grabs the foreign object, the electric push rod 26 retracts to remove the foreign object from the line area, thus preventing the foreign object from causing short circuits or grounding faults and ensuring the safe operation of the line.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
