A transmission line insulator automatic cleaning robot arm

Abstract

The invention discloses a mechanical arm for automatic cleaning of transmission line insulators, which includes: a transverse moving platform, a longitudinal moving platform, a big arm, a small arm, and an end effector. The longitudinal movement platform is set up on the first ball screw nut seat of the transverse movement platform; the big arm is fixed on the second ball screw nut seat of the longitudinal movement platform; one end of the small arm passes through the first ball screw nut seat. The steel wire drive guide wheel is hinged at the end of the big arm, and the other end is hinged at the end effector through the second steel wire drive guide wheel; the small arm is driven by the first steel wire rope, and the third stepper motor drives the first steel wire winding wheel to rotate. The first steel wire rope moves; the end effector drives the second steel wire transmission guide wheel to rotate the second steel wire rope through the fourth stepper motor. The patent of this invention proposes a four-degree-of-freedom automatic cleaning arm to clean the surface contamination of overhead line insulators, improve operating efficiency, and reduce the labor intensity of electric workers.

Description

technical field [0001] The invention relates to an automatic cleaning mechanical arm for transmission line insulators, which belongs to the field of electric power systems, in particular to an automatic cleaning device driven by a stepping motor, which can automatically clean the dirt on the surface of transmission line insulators. Background technique [0002] Overhead transmission line insulators have been operating under natural conditions for a long time, and their surfaces are polluted by solid, liquid, and gaseous conductive substances. Under the humid action of fog, dew, and drizzle, the conductance of the dirty layer on the surface of the insulator increases, and the leakage current increases, resulting in local Discharge, the partial arc on the surface of the insulator under the operating voltage will develop into a complete flashover. The flashover process of polluted insulators generally goes through four stages, namely fouling, wetness, dry area and partial arc, ...
