The invention discloses a high-energy ray lead wire foreign matter removal apparatus carried by an unmanned aerial vehicle. The apparatus comprises a laser seat, wherein cooling fins are mounted at the lower part of the laser seat; eight fixing holes are vertically formed in the upper part of the laser seat; the intervals of the adjacent fixing holes are same; laser emitters are mounted in the fixing holes; and a step motor is mounted on one side of the laser seat. The apparatus is used for emitting high-energy rays and can cut common foreign matters (such as plastic cloth and the like) at a distance of 3 meters. According to the apparatus, the laser seat is a constructed copper module and the cooling fins are attached to the back part of the laser seat; each of the eight small emitters has the power of 3.5W, the emitted ray wavelength of 445nm, the working voltage of 5V and the working current of 2A; and lenses are additionally mounted, so that meter-range internal focusing can be realized.
