The invention discloses an unmanned plane for removing a foreign matter electrically. The unmanned plane comprises a rotor craft, wherein the central position of the upper surface of the rotor craft is connected with a first bracket; the top of the first bracket is connected with a fixing sleeve; the fixing sleeve is connected with the lower end of a second bracket; the top of the second bracket is articulated with a left gripper and a right gripper; a left bracket and a right bracket are respectively arranged on the second bracket; the left bracket is articulated with a left telescopic motor; the right bracket is articulated with a right telescopic motor; a telescopic rod of the left telescopic motor is articulated with the middle part of the left gripper; the telescopic rod of the right telescopic motor is articulated with the middle part of the right gripper. By being operated on the ground by a worker, the unmanned plane disclosed by the invention can correctly reach a place below a cable of the foreign matter and can be used for capturing the foreign matter through closing of the left gripper and the right gripper so as to finish the work of clearing the foreign matter; the foreign matter suspended on a wire can be safely, rapidly and conveniently removed without power cut or climbing operation, so that the safety of people and equipment is reliably guaranteed and the work efficiency is greatly improved.
