The invention relates to a device for removing foreign matters in an electric
transmission line, and belongs to the technical field of
electric power. The device comprises a support frame and a set of cleaning cylinders hinged to the periphery of the support frame, wherein the set of cleaning cylinders is of a two-section type split structure, at least two sets of traveling mechanisms are arranged inside each cleaning cylinder in the direction of the electric
transmission line, and each traveling mechanism comprises a pair of traveling wheels and a first motor which are symmetrically arranged up and down; the interior of each cleaning cylinder is further provided with a sweeping mechanism, each sweeping mechanism comprises four hairbrush rollers and a second motor, each hairbrush roller comprises a roller and a hairbrush on the surface of the roller, a mounting ring with an L-shaped cross section is arranged at one end of each cleaning cylinder, a
graphite ring of a two-section type structure is mounted at the concave position of the mounting ring, a
cutting mechanism is mounted on the periphery of the
graphite ring, and the
cutting mechanism comprises a rotating ring with a driving mechanism and a set of
cutting knives annularly arranged on the outer side of the rotating ring.
Cutting, drilling and stripping of suspensions and coverings and sweeping of relatively small impurities can be realized, the effect of removing the foreign matters is obviously promoted, and the removal of the foreign matters on the electric
transmission line can be realized in deed.
