Description

Technical Field

[0001] The utility model relates to the technical field of identification plate devices, in particular to an identification plate device that is convenient for unmanned aerial vehicle (UAV) inspection of power transmission lines. Background Art

[0002] As we all know, traditional transmission line inspections rely on manual inspections. To facilitate inspections, most transmission line signage is mounted vertically on the tower or fixed to the tower with screws. However, with the increasing popularity of drone technology, transmission line inspections are gradually being conducted using drone vision.

[0003] After searching, a Chinese patent discloses a sign device that is convenient for drone inspections of transmission lines. The publication number is: CN210667512U, which includes a sign and at least one sign bracket. The sign bracket includes a snap-on portion and a clamping portion arranged at one end of the snap-on portion; a slot extending along the length of the snap-on portion is provided on the side of the snap-on portion; the clamping portion is detachably connected to the transmission line tower; the sign is horizontally assembled on the sign bracket through the snap-on slot of at least one sign bracket; the identification surface of the sign assembled on the sign bracket faces the sky.

[0004] Usually, the height of the tower is high and the wind speed in the upper layer is relatively high. In order to ensure the stability of the signboard, the area of the signboard will not be large. Although the above-mentioned signboard device is set to be horizontal and the drone can observe it by looking down, the drone can only use the tower as a reference. The volume of the signboard is still small relative to the tower, so the search time is increased and the work efficiency is reduced. Utility Model Content
