Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line operation and maintenance, and specifically relates to a lightning protection device for power transmission line operation and maintenance. Background Art

[0002] When laying existing transmission lines, it is necessary to connect the lightning protection equipment to the grounding body, but most grounding wires need to be wound during installation, and the installation of access equipment and grounding wires is cumbersome. At the same time, the connection between the access equipment and the grounding wire is not firm and is prone to falling off. Among them, the "A Lightning Protection Device for Transmission Line Operation and Maintenance" disclosed in the application number "CN201922189300.X" is also an increasingly mature technology. By turning the hand wheel, the user can twist the hand wheel so that the hand wheel drives the bidirectional threaded rod to rotate, so that the two clamps clamp the fixing plate, and the rod will enter the circle opened by the fixing plate. When the ground wire is removed, the nut can be loosened and the hand wheel can be turned in the opposite direction to move the two clamps away from each other. This releases the fixation of the fixing plate and enables the removal of the ground wire. However, the device also has the following defects: when fixing the ground wire, auxiliary equipment is required for subsequent adjustment. At the same time, there is a lack of stable supporting structure when the equipment is installed. When the equipment is fixed, the base needs to be fixed with screws. The fixing force of the screws is limited, the structure is unstable, and an effective pulling force cannot be formed on the bottom. In addition, each component needs to be installed separately when the equipment is installed, and it cannot be assembled in one step. Utility Model Content
