Unmanned patrolling airplane for power transmission line

The utility model relates to an unmanned patrolling airplane for a power transmission line, which comprises an airplane body, a picture pick-up system, a cradle head, a nano battery, an airplane control system, a wireless launching system, a GPS (global positioning system) and a ground receiving control treatment system; the unmanned patrolling airplane for the power transmission line is provided with four ailerons; the four ailerons are symmetrically mounted on the two sides of a main beam; the unmanned patrolling airplane for the power transmission line is stable in flying, high in flying speed, high in flexibility and load capacity; a front beam and a rear beam are designed section by section, so that adjustment and routing are facilitated. Aileron rods of the ailerons are movably connected onto aileron fixing racks through bolts; a folding positioning seat is mounted on each aileron fixing rack; the aileron rods rotate by taking the bolts as centers and are limited by the folding positioning seats; with adoption of the structure, the folded ailerons can be drawn close on the main beam in parallel, and the unmanned patrolling airplane is small in size and convenient to carry; when the front aileron rod and the rear aileron rod are unfolded, central points of four motors on the front and rear aileron rods are connected to form a square; With adoption of the structure, the unmanned patrolling airplane for the power transmission line can fly in balance, reduces current loss and is long in flight time.
