An improved detection robot for horizontal single insulator string

Abstract

The invention discloses an improved horizontal single-link insulator string detection robot, which includes two crawler mechanisms symmetrically arranged on the horizontal insulators, the two crawler mechanisms are connected to each other, and the two crawler mechanisms are respectively connected to the corresponding balance device. The balancing devices are respectively arranged on both sides of the horizontal insulator to lower the center of gravity of the robot and prevent the robot from deflecting. The balancing device includes a battery box, a control box and other auxiliary equipment. The control box controls the crawler mechanism to travel, with the The balance device of the control box is provided with an insulator live detector, and the insulator live detector includes a detection probe that swings back and forth. The invention has the advantages of reasonable structure, convenient operation, good safety, little wear on insulators, wide application range, and can adapt to live detection operation of horizontal single-connected and horizontal double-connected insulator strings.

Description

technical field [0001] The invention relates to an improved horizontal single insulator string detection robot. Background technique [0002] With the continuous development of my country's power system, more and more attention has been paid to the safe and stable operation of the power grid. Especially in the EHV and UHV transmission systems that have been vigorously developed in recent years, the safe operation of insulators directly determines the investment and safety level of the entire system. It is necessary to detect the electrical performance of the line, especially the insulation safety performance of the insulator, to prevent the occurrence of short circuits or short circuits. [0003] According to different installation structures, the insulator strings can be divided into suspension insulator strings and horizontal insulator strings. The towers that bear the tension of the wires by using the tension insulator strings to suspend or split the wires are called ten...

Problems solved by technology

Comprehensive analysis, this patent mainly has the following disadvantages: its traveling mechanism adopts the form of two crawler wheels erected on two strings of insulators, it can only walk along the horizontal double-connected insulator strings, and cannot detect the horizontal single-connected insulator strings. limitations

However, this patent application is mainly aimed at the detection of live suspended insulator strings. When it moves on the horizontal insulator string, because the surface of the insulator sheet is different when it moves forward and backward, its wheel claw structure contacts the bottom surface of the insulator sheet when it runs in the reverse direction. Causes a jamming phenomenon, making it unable to operate normally on the horizontal insulator string

[0009] Generally, the two strings of insulators in the horizontal double connection are not absolutely symmetrical due to installation errors. The center-to-center distance of string insulators is different at both ends, showing a V-shaped distribution. Therefore, the mechanism design across two strings of insulators must have the function of adjusting the distance. The robot will be deflected on the two strings of insulators, and the probe When swinging back and forth to detect two strings of insulators, one side will not be able to hit the steel cap, and the detection position needs to be adjusted
