Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line obstacle clearing sawtooth tools, and in particular relates to an automatic cleaning device for power transmission line obstacle clearing sawtooth. Background Art

[0002] With the continuous development of my country's modernization construction, the construction of power grids has also been developing continuously. However, in actual line inspection work, tree branches bring great difficulties to the maintenance of transmission lines of distribution networks. Workers need to clean the branches next to the distribution network from time to time to ensure the normal operation of the transmission lines. In order to clean the branches near the power lines, usually, when cleaning the branches, workers will carry tools such as electric saws or traditional hand saws to achieve branch clearing operations. However, after long-term use of electric saws or traditional hand saws, debris such as wood chips will be stuck in the saw teeth. Especially after cutting wet and rotten branches, rotten bark and other debris will often be stuck. If not cleaned in time, the saw teeth will rust or corrode, shortening the service life of the saw teeth, resulting in a short working time of the electric saw or even inability to work, affecting the cleaning efficiency; therefore, it is very necessary to provide an automatic cleaning device for power line obstacle clearing saw teeth with a reasonable structure, easy to use and good cleaning effect. Summary of the invention
