Embodiment

[0018] A device for eliminating the corona of the rotor UAV rotor. The UAV is suspended and lapped on the overhead wire through an insulating hanging rod. When the inspection camera is used to perform equipotential operations on the overhead wire, the body and the overhead wire With the same high potential, the vicinity of the tip of the rotor is easy to dissociate in the air, and a discharge will occur, forming a corona.

[0019] It includes a drone and a support rod 1. The drone includes a rotor 3 and a rotor arm 4 below the rotor. There are multiple support rods, which are evenly installed on the rotor arm. The angles between adjacent support rods are equal. , a plurality of support rods have a triangular pyramid structure, the pressure equalizing ring 2 is fixed on the other end of the plurality of support rods, and the pressure equalizing ring 2 is on the same level as the rotor arm of the drone.

[0020] Such as figure 1 and figure 2 and image 3 As shown, in this em...

Abstract

The invention discloses a device for eliminating the corona of a rotor wing of a rotor wing type unmanned aerial vehicle. The device comprises supporting rods and pressure equalizing rings; the plurality of supporting rods are arranged and one end of each of the supporting rods is fixed on a rotor wing arm below the rotor wing of the unmanned aerial vehicle; the pressure equalizing rings are fixed at the other ends of the plurality of supporting rods; the pressure equalizing rings and the rotor wing of the unmanned aerial vehicle are located on the same plane. By fixing the pressure equalizing rings on the plane where the rotor wing is located through the supporting rods, high pressure is uniformly distributed around the rotor wing and no potential difference is formed between each two parts of a ring shape, so that the pressure equalizing effect is realized, and furthermore, a rotor wing corona phenomenon is eliminated.

Description

technical field [0001] The invention relates to unmanned aerial vehicle technology, in particular to a device for eliminating the corona of the rotor of a rotary-wing unmanned aerial vehicle. Background technique [0002] High-voltage transmission lines are the arteries of the power system, which are directly related to the development of the national economy and the normal life of the people, so their safe operation has been paid more and more attention by departments at all levels. [0003] The failure of high-voltage transmission lines caused power outages, which caused huge economic losses to people's lives, industrial enterprises and the country. It is necessary to discover the hidden dangers and defects of the transmission line in time, and repair them to prevent problems before they happen. Regular inspections of the transmission lines must be carried out. Defects of transmission lines mainly include broken strands, loose strands, rust, defect, missing, displacement,...
