Abstract

The invention relates to a power line fault overhaul unmanned aerial vehicle with a live-working function, relates to the field of electric power overhaul, and aims to solve the problems that an existing unmanned aerial vehicle only can make a simple inspection tour, a power fault cannot be eliminated under complicated conditions, the existing unmanned aerial vehicle only can transmit a plane picture to a ground operator, and a complicated power fault is difficult to precisely diagnose. A multi-point image collecting system is used for collecting image information around the unmanned aerial vehicle; an image analyzing and processing system is used for analyzing and integrating the received image information into 3D images; a 3D visual multi-dimension control system is used for receiving the 3D images, and further used for sending a mechanical arm control signal and an unmanned aerial vehicle control signal to a signal transmission system so as to control a multi-rotor unmanned aerial vehicle body, a clamping device and a line trouble elimination mechanical arm. The live-working power line trouble shooting unmanned aerial vehicle is suitable for overhauling a power line.

Description

technical field [0001] The invention relates to the field of electric power maintenance. Background technique [0002] In recent years, with the rapid development of my country's economy, the scale and transmission distance of UHV AC and DC power overhead transmission lines in my country are also increasing day by day. In order to ensure the stable operation of the power system, power companies often use manual inspections to check and detect the power transmission network one by one with a wide coverage area, complex terrain and harsh natural environment. Not only the inspection efficiency is low, but also it is difficult to find and eliminate the equipment defects of insulators, power fittings and transmission wires on the upper part of the tower. In particular, in order to ensure that the power grid can continuously and reliably supply power to users, power companies often conduct inspections and inspections while the electrical lines are live, which poses a great potent...
