[0002] Copper high-voltage cable is a cable that uses copper as a conductor material and is filled with insulating material. It is commonly used in power transmission and distribution. Copper high-voltage cable has good transmission performance, stable voltage transmission and low power loss. Therefore, copper high-voltage cable can provide a stable power supply and reduce energy waste.

[0003] However, existing copper cables may rust during use in some extreme environments, so the cables need to be inspected regularly. Existing inspection methods usually use manual inspection and visual inspection by helicopter. However, the above two inspection methods are not accurate and have low inspection efficiency.

[0004] Therefore, the present invention provides a close-up corrosion detection device and a drone to solve the above-mentioned problems. Summary of the invention

[0005] Existing copper cables may rust during use in some extreme environments, so the cables need to be inspected regularly. Existing inspection methods usually use two methods: manual inspection and helicopter close visual inspection. However, the above two inspection methods are not accurate and also have the problem of low detection efficiency. The present invention provides a close-range corrosion detection device and a drone.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A close-up corrosion detection device includes a locking device and a monitoring mechanism. The locking detection device is installed on a drone, and the locking device is used to lock the drone on the wire and cooperate with its internal detection mechanism to achieve detection; the monitoring mechanism is installed on the other side of the locking device, and the monitoring mechanism is used to take photos of the wires for detection, and transmit the photos to a control terminal at the same time;

[0008] The rotating screw can be driven to rotate by the rotating motor in the locking device, thereby rotating the rotating gear plate, which drives the rotating connecting rod to rotate, and the rotating triangular plate rotates to drive the rotating arm to rotate, thereby driving the moving roller to shrink and get stuck on the wire to be detected, thereby locking the drone on the wire. At this time, driving the moving motor can make the detection device automatically perform detection on the wire, avoiding manual climbing to the cable for detection, thereby improving the detection efficiency; at the same time, by arranging the detection mechanism on the moving roller, while the moving roller moves forward, the telescopic detection rod in the detection mechanism periodically contacts the cable, thereby realizing the detection of the cable, thereby improving the accuracy of the detection.

[0009] As a preferred technical solution of the present invention, the locking device includes a driving mechanism, a fixed bracket, a rotating arm, a fixed arm, a mobile motor, a mobile roller and a detection mechanism, the driving mechanism is installed at the bottom of the drone, the fixed bracket array is installed on both sides of the drone, a rotating arm is installed between the fixed brackets, a fixed arm is installed on the rotating arm, a mobile motor is installed on the fixed arm, a mobile roller is installed at the output end of the mobile motor, and a detection mechanism is installed in the mobile roller; when it is necessary to detect the cable, the staff controls the drone to fly under the cable to be detected, and at this time the driving mechanism drives the locking device to lock, that is, the driving mechanism drives the rotating arm to rotate, the rotating rotating arm drives the fixed arm to rotate, and the fixed arm rotates to make the mobile roller stuck on the cable, and at this time the staff controls the mobile motor to move, thereby realizing the movement of the detection device on the cable, and while the mobile roller moves, the detection device periodically contacts the cable to be detected, thereby completing the detection of the cable to be detected;

[0010] The above method can realize the detection of cables without the need for workers to climb to the cables to be detected, which further improves the detection efficiency compared with the existing technology. At the same time, due to the design of multiple mobile rollers, the same section of cable can be tested multiple times, further improving the detection accuracy and the stability of the detection device on the cable.

[0011] As a preferred technical solution of the present invention, the driving mechanism includes a rotating motor, a rotating screw, a rotating gear plate, a rotating connecting rod, a rotating triangular plate, a stretching rod and an articulated fixing sleeve, the rotating motor is installed at the bottom of the drone, the output end of the rotating motor is installed with a rotating screw, the rotating gear plate is installed at the bottom of the drone, the rotating gear plate is meshed with the rotating screw, one end of the rotating connecting rod is installed on the rotating gear plate, the rotating connecting rod has two and is symmetrical along the center position of the rotating gear plate; the other end of the rotating connecting rod is connected to a corner of the rotating triangular plate, the rotating triangular plate is installed at the bottom of the drone, one end of the stretching rod is installed at the other two corners of the rotating triangular plate, the other end of the stretching rod is installed with an articulated fixing sleeve, the articulated fixing sleeve is installed on the fixed bracket and a rotating arm is installed thereon;

At the same time, during the detection process, the telescopic detection rod is in contact with the cable, thereby ensuring the accuracy of its detection. At the same time, due to the design of multiple fixed disks, the same section of cable can be detected multiple times, further improving the detection accuracy.
