Description

Technical Field

[0001] The utility model relates to the technical field of overhead power transmission line detection and maintenance, in particular to a live flaw detection imaging connection frame for unmanned aerial vehicles. Background Art

[0002] In overhead transmission lines, tension clamps are key components used to fix and support conductors. Due to long-term exposure to the natural environment, they are susceptible to a variety of environmental factors, such as wind, rain, lightning, temperature changes, etc. These factors may cause fatigue fracture, rust, wear and other problems in tension clamps. These problems will not only affect the normal operation of the line, but may also cause safety accidents. Therefore, it is very necessary to regularly perform flaw detection on tension clamps.

[0003] At present, drones are increasingly used in overhead line flaw detection because of their strong maneuverability, less terrain restrictions, and high operational safety. However, drone flight time is generally short, usually around 30 minutes, so how to use drones for flaw detection more efficiently is an important issue. At the same time, conventional drones are all one imaging board, which cannot be switched during flaw detection. For this reason, we propose a drone live flaw detection imaging connection frame.
