Problems solved by technology

However, the freezing point of the deicing agent prepared by this invention is between -35.1 and -38.5, and the deicing rate is slow under low temperature conditions or in a short period of time, and the deicing effect is poor, so it is not suitable for deicing and deicing of power transmission lines.

Abstract

The invention discloses a comprehensive maintenance device for an electric power line. The device comprises a conveyor dolly, wherein the conveyor dolly is provided with a suspension mechanism used for suspending a to-be-maintained device, a maintenance platform used for maintaining the to-be-maintained device, a de-icing mechanism used for clearing ice on the to-be-maintained device and a dryingmechanism used for drying the de-iced to-be-maintained device, wherein the de-icing mechanism comprises a liquid storage tank and a liquid pump arranged on the conveyor dolly, the liquid storage tankis internally stored with liquid de-icing agent, a water pumping port of the liquid pump is communicated with the liquid de-icing agent in the liquid storage tank through a water inlet pipeline, a water outlet of the liquid pump is communicated with a spraying gun through a water outlet pipeline, the conveyor dolly is provided with a vertical rod, and an upper portion of the vertical rod is provided with a suspension ring for suspending the spraying gun. The device is advantaged in that on one hand, de-icing and maintenance operation can be performed after dismounting devices on the electric power line, on the other hand, the used de-icing agent has advantages of low freezing point, fast de-icing rate in a short time, remarkable de-icing effect and little damage to carbon steels and plants.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance, in particular to a power line comprehensive maintenance device. Background technique [0002] Electric energy has become the main driving force of modern production. As a basic public utility, it has played a pivotal role with the continuous improvement of people's living standards. Power supply interruption will have serious consequences. As an important part of the power grid, transmission lines have many points, wide areas, and long lines. They are exposed to the wild for a long time and are extremely vulnerable to damage from various external forces. In addition, with the rapid development of social economy, the speed of urban-rural integration is accelerating, and the scale of cities is constantly expanding. At the same time, the construction of power grids is also developing rapidly. More changes have brought many problems to the operation and maintenance of transmissi...
