Description

Technical Field

[0001] The invention relates to the technical field of wind turbine blades, in particular to an anti-damage device for laying a web lightning conductor. Background Art

[0002] The web is a lightning protection device installed on the internal web structure of the wind turbine blade. Its main function is to guide the lightning current to the root of the blade to prevent the composite materials and electrical equipment inside the blade from being damaged after the lightning directly hits the blade. Wind turbine blades are usually in a relatively open and high environment and are easily targeted by lightning. The lightning protection wire is like a "safe passage" that can effectively protect the blades.

[0003] By searching patent number 2024107967846, the wind turbine blade lightning conductor laying tooling includes a workbench, a support frame, two drive support mechanisms and two clamping and conveying mechanisms. The synchronous belt of the drive support mechanism is meshed with the transmission gears of multiple drive support components to drive the drive cylinder to rotate; the outer surface of the conveyor belt of the clamping and conveying mechanism is provided with multiple rotating clamps. When in use, the rotating clamp clamps the lightning conductor, and the conveyor belt drives it forward. The lightning conductor falls on the driving cylinder, and the driving cylinder provides driving force to reduce the tension on the lightning conductor and protect the structure on the core of the lightning conductor. During use, it is found that the clamping mechanism is easy to damage the outer surface of the lightning conductor, affecting the insulation resistance of the lightning conductor. At the same time, the cost is relatively high and the use is complicated. Summary of the invention
