FLIGHT METHOD OF UNMANNED FLYING OBJECT, AND INSPECTION METHOD OF POWER TRANSMISSION FACILITY UTILIZING UNMANNED FLYING OBJECT

摘要

To perform efficiently and safely an inspection work of a transmission line or the like.SOLUTION: A fall prevention device is fitted on a main rope (safety wire), and an unmanned flying object is connected to a lock lever of the fall prevention device. While putting a lock mechanism into a lock release state by setting the lock lever to the upper side by thrust of the unmanned flying object, the unmanned flying object is raised along the main rope together with the fall prevention device. Then, while maintaining the lock lever in the lock release state by thrust of the unmanned flying object, the unmanned flying object is lowered along the main rope together with the fall prevention device. When the unmanned flying object loses thrust necessary for flight, the lock lever is set to the lower side by self-weight of the unmanned flying object, to thereby put the lock mechanism into the lock state.SELECTED DRAWING: Figure 8
