technical field

The utility model relates to an atomizing cleaning head for an overhead power transmission line.

Background technique

At present, the overhead transmission lines laid in the early stage, especially the Southern Power Grid, generally adopt the form of bare wires to save construction costs. But there are also greater security risks. Kites and other sundries that are accidentally suspended on overhead transmission lines, and dust accumulated on insulators, clamps, and anti-vibration hammers can easily form mud flows and cause short circuits on the lines, thereby causing accidents such as tripping. In order to improve the transmission safety of bare overhead transmission lines, it is necessary to use artificial spraying of insulating varnish to improve its insulation performance. However, before manual spraying or machine spraying operations, it is necessary to use a cleaning solution to clean the exposed and leaked overhead transmission lines to remove accumulated dust and residual oils.
