Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line sealing technology, and more particularly to a split-type automatic online power transmission line sealing device and a sealing method. Background Art

[0002] During the construction of transmission lines, crossings over important facilities are common, with increasingly higher heights, more frequent crossings, and more complex construction conditions. Crossing over important facilities requires network closure for protection. However, in practice, the time allowed by the management of the facilities being crossed is very short, making the ability to safely and quickly close the network within this limited time a critical task.

[0003] However, existing transmission line sealing technology relies on traditional manual installation of insulation nets using spanning sealing devices. Most spanning sealing devices are constructed using materials such as steel pipes, guy wires, drilled piles, and insulating ropes. This method presents the following issues: 1. The manual laying of the insulation net not only prolongs the construction period of the transmission line network and increases the labor intensity of the laying personnel, but also makes the laying, disassembly and recycling of the insulation net very troublesome.

[0004] 2. The laying of the insulation net requires a lot of manpower and materials, which is not only costly, but also has low efficiency in crossing the net closure, and also affects the subsequent power construction process.

[0005] 3. The applicable scenarios of mainstream crossing sealing devices are limited. Mainstream crossing sealing devices are large in size and rely on flat ground environments. They are difficult to adapt to complex terrains such as the wild and densely wooded areas for laying insulation nets. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a split-type automatic transmission line sealing device that can quickly and effectively complete the laying of the insulation net, achieving efficient sealing construction for the erection and crossing of transmission lines.
