Wind Turbine Tower Bracing Cable Guide Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bracing cables in wind turbine towers with concave shapes can vibrate and come into contact with the tower wall due to manufacturing tolerances, leading to potential damage, as existing securing methods do not effectively account for variable cable positions.
Innovation Solution
A device comprising a guide bracket and bracket mount allows for adjustable placement of the guide bracket along the tower wall, enabling bracing cables to be guided outwardly without form-fitting constraints, accommodating manufacturing tolerances and redirecting cables in concave sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bracing cables are guided in rigid attachments to prevent contact with the tower wall, then cable stability is improved, but the attachment must withstand substantial circumferential forces generated by manufacturing tolerances
Solution Approach 1:
The guide bracket is designed with a pivotable connection to the attachment, allowing it to rotate dynamically around the cable axis. This dynamic adjustment enables the guide bracket to adapt to manufacturing tolerances and cable position variations without generating substantial circumferential forces on the attachment, while still preventing harmful contact with the tower wall.
2Measurement precision
If bracing cables are tensioned in rigid attachments, then cable positioning is improved, but excessive circumferential forces are generated that require stronger anchoring
Solution Approach 1:
The pivotable guide bracket allows the cable to be tensioned while automatically adjusting to the correct position without generating excessive circumferential forces. This eliminates the need for complex, high-strength anchoring designs, simplifying the manufacturing process while maintaining precise cable positioning.
3Measurement precision
If guide brackets are fixed in position to guide cables accurately, then guiding precision is improved, but adaptability to manufacturing tolerances deteriorates
Solution Approach 1:
The guide bracket's ability to pivot around the cable axis provides adaptability to manufacturing tolerances while maintaining guiding precision. The dynamic adjustment allows the bracket to accommodate cable position variations without compromising its ability to prevent contact with the tower wall.
Solution Approach 2:
The pivotable connection acts as an intermediary mechanism between the fixed attachment and the flexible cable, mediating the conflict between precision and adaptability by allowing controlled movement that accommodates tolerances while maintaining guiding function.

AI summary
A device for guiding bracing cables in a tower of a wind turbine. The device comprises at least one guide bracket to be arranged in the tower between a tower wall and at least one of the bracing cables, such that the at least one bracing cable bears against the guide bracket and is thereby guided along the tower wall, and a bracket mount for attaching the guide bracket to the tower wall, wherein the position of the guide bracket in the circumferential direction of the tower along the bracket mount can be changed in order to match the position of the at least one bracing cable.
