Power transmission line stockbridge damper surface defect detection device and method

Abstract

The invention discloses a power transmission line stockbridge damper surface defect detection device and a power transmission line stockbridge damper surface defect detection method, which belong to the technical field of power transmission line stockbridge damper surface defect detection. The power transmission line stockbridge damper surface defect detection device comprises a pay-off mechanism,a reset line, a displacement mechanism, a detection mechanism, a power transmission cable and a detection system. After a line detection worker climbs to a power transmission line tower, an insulating roller is clamped on the power transmission cable and rolls downwards along the power transmission cable; when a bracket transverse plate moves to the upper parts of stockbridge dampers, the stockbridge dampers are magnetized and is gradually close to a saturation state under the action of a direct-current magnetic field emitted by an electromagnetic disc; a leaked abnormal magnetic field is captured and detected by means of a magnetic sensor, and a detection result is sent to the detection system; the background personnel can observe the surface defect conditions of the stockbridge dampersin real time through using a platform terminal and judge whether the stockbridge dampers reach a replacement standard or not, the stockbridge dampers does not need to be dismounted one by one in the whole detection process, workers only need to check the stockbridge dampers on the power transmission line tower, and the use process is safer.

Description

technical field [0001] The invention relates to the technical field of power transmission line detection, in particular to a device and method for detecting surface defects of a power transmission line anti-vibration hammer. Background technique [0002] Anti-vibration hammer is widely used in transmission lines. Its function is to consume the intensity of breeze vibration and protect the transmission wire from fatigue damage. Affected by the gravity of the transmission wire itself, the overhead wire is in an arc state with high ends and low middle. Therefore, the installation angle of the anti-vibration hammer is usually inclined. After being exposed to the wind and sun in the external environment, cracks and other defects will appear on the surface of the anti-vibration hammer. Regularly detect the surface defects of the anti-vibration hammer in order to replace the anti-vibration hammer in time. The existing surface inspection process of the anti-vibration hammer is to re...

Problems solved by technology

[0003] The purpose of the present invention is to provide a device and method for detecting surface defects of anti-vibration hammers of transmission lines that are more convenient to use, do not need to be disassembled one by one during detection, save the workload of workers, and improve the safety of the detection process, so as to solve the problems in the above-mentioned background technology. The surface detection process of the proposed anti-vibration hammer is very cumbersome, and workers are prone to safety accidents during the assembly and disassembly process, and the practicability is not high.
