[0002] Traditional overhead line tension clamp flaw detection usually relies on manual operation, requiring workers to climb to a high place to use an X-ray flaw detector for inspection. This method is not only time-consuming and labor-intensive, but also poses a great risk to personal safety. In addition, power outages are often required during flaw detection, which will lead to power supply interruptions, bring inconvenience to social production and life, and may cause economic losses.

[0039] The walking mechanism 5 is driven by the drone and is set on the tension clamp. Then, it moves along the extension direction of the tension clamp and the conductor. During the movement, the grooved pulley 502 rotates under the action of the friction force of the tension clamp, and the second transmission shaft 505 is driven to rotate by the cooperation of the third gear umbrella 5052 and the fourth gear umbrella 5021.

[0043] The walking mechanism 5 guides the UAV so that the equipment frame 4 moves along the tension clamp and the conductor during its forward flight, thereby irradiating the tension clamp with an X-ray device and detecting flaws in the tension clamp by analyzing the received data on the imaging plate 3 .

[0047] When the quick-connect male connector 401 is inserted into the quick-connect female connector 105, the expansion plug 4015 is rotated to slide along the tapered hole 4013, so that the top of the quick-connect male connector 401 expands outward, so that the card slot 4011 is stuck on the edge of the limiting flange 1052, and the drone is fixed to the equipment rack 4.

The grooved pulley 502 and the cleaning plate 503 are installed in the dust cover 501 and are rotatably connected thereto. The walking mechanism 5 is movably connected to the equipment frame 4 .

[0076] Furthermore, the equipment frame 4 is a rectangular plate-like structure, and an insulating sling 404 is provided at the upper end of the equipment frame 4. The equipment frame 4 and the drone are fixed by the insulating sling 404. The imaging board 3 is fixedly installed on the left and right sides of the equipment frame 4. A slide rail 1011 is provided on the landing gear 101, and the X-ray machine 2 is installed on the slide rail 1011 and is slidably connected thereto, and a locking bolt is provided on the side of the X-ray machine 2.

[0077] Through the cooperation of multiple groups of drones, one group of drones places the imaging plate 3 between the double-split conductors, and then the other two groups of drones drive the X-ray device to irradiate both sides of the imaging plate 3, thereby realizing the flaw detection of the multi-split tension clamp.

[0078] Furthermore, the number of the traveling mechanisms 5 is four, and the four groups of traveling mechanisms 5 are respectively installed on the left and right sides of the front end and the left and right sides of the rear end of the equipment frame 4, and the traveling mechanisms 5 and the equipment frame 4 are fixed by bolts.

[0079] The equipment frame 4 is supported by four sets of walking mechanisms 5 so that the imaging plate 3 can be stabilized in the middle of the double split conductors, thereby ensuring the stability of imaging.

[0080] In this embodiment, when the equipment is in use, the staff wears protective equipment. First, two sets of imaging plates 3 are installed on the left and right sides of the equipment frame 4, and then the equipment frame 4 is fixed to the landing gear 101 of the carrier drone 1 through the insulating sling 404, and the imaging plate 3 is connected to the power supply 103 of the carrier drone 1. Then two carrier drones 1 are taken, and the X-ray instrument is installed on the slide rail 1011 above the drone shielding plate 104, and the power supply 103 is turned on. The carrier drone 1 with the imaging plate 3 is flown between the double-split conductors, and the walking mechanism 5 is set on the conductors. Then the carrier drone 1 with the X-ray instrument is flown to both sides of the conductors, and the X-ray instrument emits X-rays toward the imaging plate 3, and the multi-split tension clamps are simultaneously inspected for flaws.

[0081] It should be noted that the X-ray machine 2 unit uses the ImageMaster series of X-ray flaw detection digital imaging system series, which is a portable detection equipment for power fittings such as wire clamps designed and launched for the power industry. The signal receiving end is a wireless receiver and a portable computer running digital image acquisition software and image enhancement tool ImageMaster. The image data is converted into wireless data for transmission through a specially customized small high-bandwidth device, and the transmission of a single-frame image file can be completed within 1-2 seconds. After receiving the image, the ImageMaster software immediately performs necessary post-processing and supports display, enhancement, storage, etc. after image capture. The carrier drone 1 uses an industrial-grade drone flight controller, CNC metal processing accessories and a carbon fiber fuselage. The electric landing gear 101 is used to expand the unobstructed viewing angle below the drone; it is equipped with D-RTK The GNSS system can achieve high-precision positioning. Through real-time dynamic differential technology, the three-dimensional positioning accuracy can be improved from meter level to centimeter level. It integrates positioning, altitude determination and direction finding functions, making up for the shortcomings of traditional GPS, barometer and compass. At the same time, it is stable and reliable in complex electromagnetic environments, providing an accurate and reliable flight platform for high-precision application needs. The carrier drone 1, X-ray instrument and imaging board 3 are existing equipment in the market.
