Insulator sweeping and detecting robot for high-voltage power transmission line

Abstract

The invention discloses an insulator sweeping and detecting robot for a high-voltage power transmission line. The robot comprises an annular frame and a control box; the annular frame is capable of being opened towards the two sides around a rotating shaft and comprises an upper layer bracket, a lower layer bracket and a middle layer bracket, wherein the upper layer bracket and the lower layer bracket are fixedly connected through a plurality of auxiliary brackets; the middle layer bracket is capable of moving up and down through a sweeping layer elevating mechanism; the upper layer bracket is provided with an upper clamping jaw for clamping an insulator; a detecting device is arranged on the upper clamping jaw; the middle layer bracket is provided with a sweeping device and an auxiliary clamping jaw which is used for clamping the skirt section of the insulator; a lower clamping jaw capable of moving up and down through a clamping jaw layer elevating mechanism is also arranged between the upper layer bracket and the lower layer bracket; the annular frame opposite to the rotating shaft is provided with a locking mechanism for locking the closed state of the annular frame; a power supply and a controller which is used for controlling the running and action sequence of a rotating mechanism and a servo motor are arranged inside the control box. The insulator sweeping and detecting robot disclosed by the invention is compact in structure, good in adaptablity, complete in sweeping, high in load capacity and applicable to hot-line sweeping and detection of horizontal and suspension insulator strings.

Description

technical field [0001] The invention relates to an insulator string cleaning robot, in particular to a high-voltage transmission line insulator cleaning and detection robot, which can be used to complete the cleaning and detection of high-voltage transmission line glass and ceramic insulator string dirt, so as to replace manual cleaning of live insulators with detection robots. Background technique [0002] Because the insulators of high-voltage transmission lines are outdoors for a long time, dust is easy to adhere to the surface, which reduces its insulation capacity. In wet weather, dirty insulators are prone to flashover discharge (i.e. pollution flashover), causing power outages and threatening the safety of power supply. [0003] Cleaning the fouling of ceramic and glass insulators is one of the main tasks in the maintenance of transmission lines. At present, the cleaning of insulators is carried out with a brush or a rag by manually ascending the tower during the po...

AI Technical Summary

Problems solved by technology

Comprehensive analysis, this patent mainly has the following disadvantages: it can only run along the horizontal double-string insulator string, and cannot be applied to the suspension or single-string insulator string

The robot can realize live cleaning and detection of insulators, but because of the climbing method of alternately clamping the skirt of the insulator, the clamping force cannot be too large, so the load is limited, and because the position of the cleaning mechanism is relatively fixed, it is suitable for different models Difficult to adjust the sweeping force applied to the surface of the insulator
