Abstract

The invention discloses a remote flaw detector for in-service power equipment, and relates to the technical field of remote flaw detection of power equipment. To overcome the defect of high-altitude flaw detection of personnel, the remote flaw detector specifically comprises an unmanned aerial vehicle, a flaw detection mechanism and a synchronous lifting mechanism, wherein the unmanned aerial vehicle comprises three or more first electromagnetic adsorption mechanical claws, four rotor wing assemblies, a machine box, four racks, two fixing pieces and two second electromagnetic adsorption mechanical claws; the four racks are connected with the bottoms of the four rotor wing assemblies through bolts correspondingly; the four corners of a fixing plate are connected to one sides of the four racks through mounting pieces correspondingly, the machine box is arranged on one side of the top of the fixing plate, a mounting groove is formed in the outer wall of the top of the fixing plate, the synchronous lifting mechanism is arranged in the mounting groove, and mounting plates are fixed to the top end and the bottom end of the synchronous lifting mechanism through triangular plates correspondingly. The defect of a traditional detection method of a electric power strain clamp is overcome, the high-altitude in-situ detection problem is solved, and the personal safety problem of flaw detection staff is solved.

Description

technical field [0001] The invention relates to the technical field of remote flaw detection for electric equipment, in particular to a remote flaw detector for in-service electric equipment. Background technique [0002] Tension clamp refers to the hardware used to fix the wire to bear the tension of the wire and hang the wire to the tension string or tower. The traditional detection technology of electric tension clamp includes appearance size detection, grip force test, and electromagnetic detection. The detection positions of the electric tension clamp are mainly three positions of crimping: the crimping place between the steel anchor groove and the aluminum tube, the place where the steel core of the wire is inserted into the inner hole of the steel anchor, and the crimping place of the aluminum tube on the wire side. These three positions are the crimping parts of the electric tension clamp and are also the places where problems are most likely to occur. [0003] Und...
