Transmission line inspection robot

Abstract

The invention discloses an inspection robot for a power transmission line. The inspection robot comprises a robot body, a control device and a detecting device, wherein a signal output end of the detecting device is connected with an input end of the control device; an output end of the control device is connected with a controlled end of each controlled part of the robot body; the robot body comprises a fixed bracket; three sets of motion detecting units are arranged on the fixed bracket in parallel; each set of motion detecting units separately comprises an obstacle-crossing mechanical arm, an up-and-down motion mechanism for driving the obstacle-crossing mechanical arm to move up and down and a rotary mechanism for driving the up-and-down motion mechanism and the obstacle-crossing mechanical arm to horizontally rotate; the rotary mechanism is fixedly arranged on the fixed bracket; the up-and-down motion mechanism is arranged on the rotary mechanism; and the obstacle-crossing mechanical arm is fixedly arranged at the top end of the up-and-down motion mechanism. The inspection robot not only can realize daily inspection of the power transmission line, further can realize obstacle-crossing inspection, improves inspection precision and accuracy of the power transmission line, and provides guarantee for safety operation of the power transmission line.

Description

technical field [0001] The invention relates to the technical field of inspection of transmission lines in electric power systems, in particular to a device capable of walking along transmission lines and completing inspections. Background technique [0002] Due to the long-term exposure of transmission line equipment in the wild environment, it is attacked by various meteorological conditions (such as strong winds, ice and snow, temperature changes, lightning strikes, etc.), corrosion by chemical gases, and damage by external forces. Line damage such as wear and corrosion, and the probability of failures such as flashing of insulators, loss of tower materials, and hardware falling off are also high. If repairs and replacements are not timely, the original small damage may expand, eventually leading to power transmission interruption or even power transmission accidents . Therefore, the inspection of high-voltage transmission lines is of great significance to ensure the saf...
