Wind Turbine Foundation Pile Stabilization Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of large-diameter foundation piles for wind turbines is complicated and expensive due to the need for numerous long weld seams, which increases manufacturing costs and complexity, and larger diameters require disproportionate increases in wall thickness for stability, making bending and welding more challenging.
Innovation Solution
Incorporating a stabilization device within the foundation pile connected to inner surface sections, which distributes forces and increases lateral and torsional rigidity, allowing for a reduction in wall thickness and simplifying production by reducing the need for extensive weld seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the diameter of the foundation pile is increased to withstand larger wind forces, then the stability and load-bearing capacity are improved, but the wall thickness must be increased disproportionately, making bending and welding more complex and expensive
Solution Approach 1:
The foundation pile is divided into multiple foundation pile segments that are connected to each other. Each segment can be manufactured separately with standardized dimensions, avoiding the need to bend and weld extremely thick steel plates in a single piece. The segmentation allows for modular assembly and reduces the complexity of manufacturing each individual component.
Solution Approach 2:
Instead of increasing stability solely through wall thickness (one-dimensional solution), the invention introduces a stabilization device that spans across the interior of the foundation pile, creating a three-dimensional structural reinforcement system. This internal stabilization structure provides additional rigidity and stability without requiring disproportionate increases in wall thickness.
2Strength
If the wall thickness is increased to provide sufficient stability for large-diameter foundation piles, then the stability is improved, but the manufacturing effort and costs increase considerably
Solution Approach 1:
The foundation pile is divided into multiple foundation pile segments that are connected to each other. Each segment can be manufactured separately with standardized dimensions, avoiding the need to bend and weld extremely thick steel plates in a single piece. The segmentation allows for modular assembly and reduces the complexity of manufacturing each individual component.
Solution Approach 2:
Instead of increasing stability solely through wall thickness (one-dimensional solution), the invention introduces a stabilization device that spans across the interior of the foundation pile, creating a three-dimensional structural reinforcement system. This internal stabilization structure provides additional rigidity and stability without requiring disproportionate increases in wall thickness.
3Reliability
If numerous long weld seams are used to connect foundation pile segments, then the structural integrity is improved, but the production time and costs increase
Solution Approach 1:
The foundation pile is divided into multiple foundation pile segments that are connected to each other. Each segment can be manufactured separately with standardized dimensions, avoiding the need to bend and weld extremely thick steel plates in a single piece. The segmentation allows for modular assembly and reduces the complexity of manufacturing each individual component.
Solution Approach 2:
The stabilization device is integrated into the foundation pile segments during the manufacturing process, before assembly. This preliminary integration ensures that the stabilization functionality is built-in from the start, eliminating the need for additional现场 stabilization measures and reducing overall production time.
4Ease of manufacture
If the wall thickness is reduced to simplify manufacturing and transportation, then the production costs and transport complexity are reduced, but the stability and rigidity of the foundation pile deteriorate
Solution Approach 1:
Instead of increasing stability solely through wall thickness (one-dimensional solution), the invention introduces a stabilization device that spans across the interior of the foundation pile, creating a three-dimensional structural reinforcement system. This internal stabilization structure provides additional rigidity and stability without requiring disproportionate increases in wall thickness.
Solution Approach 2:
The foundation pile combines the steel plate structure with an internal stabilization device, creating a composite structural system. The stabilization device, which may be made of different materials or structural configurations, works together with the steel walls to provide enhanced rigidity and stability while allowing for thinner wall thickness.
