Problems solved by technology

[0002] With the continuous advancement of science and technology, unmanned aerial vehicles have been gradually applied to the power industry, and it has gradually become the trend of electric power development to eliminate defects on live lines through the unmanned aerial vehicle carrying the operating arm. When there is a foreign object on the line, due to the strong electric field interference and the characteristics of the suspended foreign object, the following problems will be encountered: If the foreign object is long and large, the foreign object may fall on the fuselage of the drone, entangle with the blade, Collision will affect the normal operation of the UAV, and even damage the UAV. The strong electric field of the live line will interfere with the weak current system inside the UAV, thus affecting the normal operation of the UAV.

Abstract

The invention provides a charged foreign matter clearing unmanned aerial vehicle protection cover, which comprises a first connecting plate and a second connecting plate, wherein the end part of the first connecting plate and the end part of the second connecting plate are mutually hinged; one end of the first connecting plate is provided with a second fixing ring; the upper part of the second fixing ring is provided with an upper protection net; the upper protection net comprises a plurality of first arc-shaped rods, a copper wire layer and a first fixing ring. The first arc-shaped rods and the second arc-shaped rods are respectively made of carbon fiber, so that the first arc-shaped rods and the second arc-shaped rods can ensure the sufficient intensity of the charged foreign matter clearing unmanned aerial vehicle protection cover, and meanwhile, the weight of the charged foreign matter clearing unmanned aerial vehicle protection cover is reduced to the maximum degree. The first arc-shaped rods and the second arc-shaped rods can surround a rotor of a charged foreign matter clearing unmanned aerial vehicle for preventing foreign matters from falling on a vehicle body of the unmanned aerial vehicle and from being wound and collided with the rotor, and the influence on the normal work of the unmanned aerial vehicle is avoided.
