Description

Technical Field

[0001] The utility model relates to the technical field of installation and detection of wind blade lightning receptors, in particular to a blade tip lightning receptor positioning tool. Background Art

[0002] The blade tip lightning rod is an indispensable part of the blade. The positioning accuracy of the blade tip lightning rod directly affects the lightning rod effect and appearance refinement of the blade. The existing wind turbine blade tip lightning rod positioning fixture has a poor chordal limit function of the airfoil clamp, which easily leads to chordal misalignment. Different tightening and loosening of the bolts in the vertical direction will lead to deviation in the vertical direction. There are the following problems: (1) When installing the lightning rod, the core material needs to be hollowed out. The process may be irregular, which will cause errors and damage the structure. (2) During the manual installation process, the effect of positioning the lightning rod is highly dependent on the skill level of the operator. Due to differences in manual operation, different batches of lightning rods may not maintain consistent installation quality, which will lead to uneven performance of wind turbine blades and affect the overall production quality. Manual positioning usually requires the use of various tools (such as measuring tools, spirit levels, etc.). If the tools are inaccurate or unsuitable, the positioning effect may also be affected. (3) During the inspection process, it may be difficult to find potential installation problems in the later quality inspection of the manually positioned lightning rod, affecting the reliability of the overall product. While manual positioning of air terminals may be necessary in some cases, its drawbacks cannot be ignored. Companies should consider using appropriate tooling or automated equipment when positioning air terminals to improve installation accuracy and consistency, reduce the risk of human error, and thus enhance product quality and production efficiency.
