AI Technical Summary

Technical Problem

The existing pre-bending device for lightning protection conductors on wind turbine blades cannot effectively position and fix the lightning protection conductors, causing them to sway during pre-bending, which affects the effect. Furthermore, the pre-bending plate is easily worn and cannot be replaced.

Method used

The design employs a lower guide plate and an upper guide plate, combined with positioning and fixing components, limiting components, and installation and disassembly components. Through the cooperation of arc-shaped bending plates, sliding grooves, and sliders, the lightning protection conductor is precisely positioned and fixed. The limiting rod is slidable by a high-voltage spring, simplifying installation and disassembly.

Benefits of technology

This achieves stable pre-bending and positioning of the lightning protection conductor, avoids swaying, extends the service life of the device, and improves operational efficiency and connection quality.

Abstract

This utility model relates to the field of wind turbine blade technology, specifically a pre-bending device for lightning protection conductors of wind turbine blades. It includes a lower guide plate body and an upper guide plate body. The lower guide plate body has a lower external mounting base installed at its bottom end and a conductor pre-bending plate at its top end. A first through hole is formed on one side wall of each lower guide plate body, and a mounting hole is formed at the top end of each lower guide plate body. A mounting rod that mates with the mounting hole is installed at the bottom end of the conductor pre-bending plate, and the mounting rod contains an installation and disassembly assembly. This utility model first uses the rotation of the threaded rod body to drive the mounting block and welding plate to slide on the outer wall of the threaded rod body. This causes the welding plate to drive the limiting plate to slide, thereby limiting and fixing the positioning plate. This improves the positioning and fixing effect of the positioning plate and the arc-shaped bending plate on the lightning protection conductor, preventing swaying during pre-bending.
