[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-3 As shown, this utility model provides a power transmission and distribution line inspection device, including a drone body 1. A square groove 2 is opened on one side of the outer wall of the drone body 1. A power supply 3 is set on the inner surface of the square groove 2. A fixing plate 4 is fixedly installed on the inner surface of the square groove 2. A hole 5 is opened on one side of the outer wall of the fixing plate 4. A power detector 6 is fixedly installed on one side of the outer wall of the fixing plate 4, and the output end of the power detector 6 passes through the interior of the hole 5. Four frames 7 are fixedly installed on the outer wall of the drone body 1. Each of the four frames 7 is provided with a fan blade 8 at the top. Two support frames 9 are fixedly installed on the outer wall of the drone body 1. A set of anti-slip pads 10 are fixedly installed at the bottom of each of the two support frames 9. A set of ultrasonic sensors 11 are fixedly installed on the outer wall of the drone body 1. A base 12 is fixedly installed on the top of the drone body 1. A circular groove 13 is opened on the top of the base 12. A micro motor 14 is set on the inner surface of the circular groove 13. A support plate 15 is fixedly installed on the output end of the micro motor 14.

[0024] The overall effect of Embodiment 1 is that the power detector 6 is connected to the power supply 3, which provides power support for the entire inspection device. The entire drone is driven to fly by the rotation of the four fan blades 8 to carry out inspection. The drone adopts non-contact inspection, which will not cause damage to the power equipment due to improper human operation or accidental collision. It is especially suitable for old or fragile poles and towers. The power detector 6 can detect the remaining power of the power supply 3 in real time. When the power is too low, it will automatically issue an alarm and return to home. The micro motor 14 can drive the support plate 15 to rotate, which can ultimately adjust the angle of the inspection device to make the inspection more comprehensive. At the same time, the anti-slip pads 10 at the bottom of the two support frames 9 can make the drone stand more stably.

[0025] Example 2, as Figures 1-4 As shown, a high-definition visible light camera 16 is fixedly installed on the top of the support plate 15, an infrared thermal imager 17 is fixedly installed on the top of the support plate 15, a positioning module 18 is set on the top of the drone body 1, a set of heat dissipation holes 19 are opened on the bottom of the drone body 1, four connecting rods 20 are fixedly installed on the bottom of the drone body 1, a connecting plate 21 is fixedly installed between the bottoms of the four connecting rods 20, an ultraviolet imager 22 is fixedly installed on the bottom of the connecting plate 21, and a data transmission module 23 is fixedly installed on the bottom of the connecting plate 21.

[0026] The overall effect of Embodiment 2 is that, when the device is in normal use, the infrared thermal imager 17 can quickly capture temperature data over a wide range and generate temperature distribution images in real time, allowing operators to intuitively monitor the detection process and understand the line status at any time. Then, the high-definition visible light camera 16 can observe whether there are cracks or dirt on the surface of the insulator, whether there are broken strands or wear on the conductor, and whether there is deformation or corrosion on the tower. At the same time, the ultraviolet imager 22 can detect potential insulation defects earlier, which helps to take timely maintenance measures and avoid further development of the fault. Finally, the data transmission module 23 transmits the collected data to the ground control system.

[0027] Among them, the main body of the drone 1, power supply 3, power detector 6, ultrasonic sensor 11, micro motor 14, high-definition visible light camera 16, infrared thermal imager 17, positioning module 18, ultraviolet imager 22 and data transmission module 23 are all existing technologies, and their components and operating principles are all publicly available technologies, which will not be explained in detail here.

[0028] Working Principle: During normal operation, the main body of the drone 1 is connected to the fan blades 8 via four frames 7 and powered by the power supply 3, allowing it to take off and move. The drone's high flight speed enables it to cover large areas of power lines and equipment in a short time, significantly improving inspection speed compared to manual inspection. This advantage is particularly pronounced in areas with complex terrain and long lines. Simultaneously, a set of ultrasonic sensors 11 are located around the main body of the drone 1, monitoring obstacle information in the surrounding environment in real time. When an obstacle is detected approaching, the drone 1 automatically performs obstacle avoidance maneuvers, ensuring the smooth operation of the inspection device during flight. For safety reasons, collisions with power transmission lines or other objects are avoided. Secondly, the power detector 6 is connected to the power supply 3, which uses a high-performance lithium battery pack with advantages such as high energy density, good charging and discharging performance, and long battery life, meeting the needs of long-term inspection operations. Furthermore, a set of heat dissipation holes 19 on the bottom of the drone body 1 allows the heat generated by the power supply 3 during use to dissipate, ensuring its normal operation. Simultaneously, the power detector 6 can detect the power supply 3's charge level in a timely manner; when the charge level falls below a set value, it automatically issues an alarm and causes the drone to return to base. Additionally, the micro motor 14 is connected to the support plate 15, and the high-definition visible light camera 16 is connected to the infrared... The external thermal imager 17 is mounted on the support plate 15. The angle between the high-definition visible light camera 16 and the infrared thermal imager 17 can be adjusted by the operation of the micro motor 14. The high-definition visible light camera 16 can capture high-definition color images of the power transmission and distribution lines and their surrounding environment, clearly showing the appearance of the lines. The infrared thermal imager 17 is used to detect the temperature distribution of the power transmission and distribution lines. It can capture abnormal hot spots caused by overload, poor contact, etc. By analyzing the temperature data, potential fault hazards can be detected in advance, effectively preventing power accidents caused by line overheating. At the same time, the ultraviolet imager 22 is used to detect insulation. The discharge status of the insulator: When there is partial discharge on the surface of the insulator, it will emit ultraviolet signals. The ultraviolet imager 22 can capture these signals and convert them into visual images to help maintenance personnel accurately judge the insulation performance of the insulator, promptly identify and replace problematic insulators, and ensure the safe and stable operation of the transmission and distribution lines. At the same time, the positioning module 18 adopts a GPS positioning system, which can accurately determine the location information of the inspection device so as to match it with the geographic information system of the transmission and distribution lines, accurately record the location coordinates of the fault point, and facilitate subsequent maintenance personnel to quickly locate it. Then, the data transmission module 23 transmits the data to the ground control system.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
