AI Technical Summary

Technical Problem

Existing drone-mounted removal devices are difficult to effectively grip and cut foreign objects entangled in high-voltage power lines, and are easily affected by wind, resulting in poor operational accuracy and low cleaning efficiency.

Method used

A fixing mechanism including a clamping component, a cutting component, and a guiding component is designed. Through a combination of hydraulic transmission and a rotary servo motor, it can clamp, cut, and guide foreign objects. It is also equipped with a positioning component to adjust the clamping height, orientation, and angle to ensure accuracy and stability.

Benefits of technology

It improves the success rate of removing foreign objects from high-voltage power lines, ensures the accuracy and stability of clamping, enhances the precision and efficiency of high-altitude operations, and avoids damage to the lines.

Abstract

The invention relates to the technical field of power line maintenance equipment, and discloses an unmanned aerial vehicle mounted high-voltage power line foreign matter insulation removing device which comprises a mounting frame, a control box, a steering engine chassis, a positioning assembly and a fixing mechanism. The mounting frame is rigidly connected to the bottom of the unmanned aerial vehicle; the positioning assembly is mounted at the right end of the steering engine chassis, and the height, orientation and angle of a follow-up mechanism are adjusted when the unmanned aerial vehicle hovers through a rotary steering engine and an electric push rod; the fixing mechanism is arranged at the right end of the positioning assembly, and a clamping assembly, a driving assembly, a cutting assembly and a guiding assembly are integrated in the fixing mechanism. During operation, the guide assembly moves along with the clamping arm to drive the guide plate to be folded towards the center, and foreign matter easy to fluctuate is guided and aligned; the clamping assembly closes and fixes the foreign matter, and the closed hydraulic driving mechanism pushes a blade of the cutting assembly to stretch out to cut off entanglements such as kite lines. Through the design of multi-degree-of-freedom adjustment, guide folding and hydraulic cutting, the high-altitude cleaning efficiency and effect are improved.
