Wind Turbine Transition Piece Platform for Service Lift Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind turbine designs require labor- and cost-intensive installation of temporary scaffolds for accessing electrical equipment, complicating the installation of array cables and maintenance of service lifts, with inefficient space utilization and increased testing requirements.
Innovation Solution
A wind turbine design featuring a permanent working platform below the service lift, suspended within the transition piece, providing access and space for servicing the lift and routing array cables, eliminating the need for temporary scaffolds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a temporary scaffold is installed below the switch gear platform to access electrical equipment, then accessibility for installation and maintenance is improved, but device complexity and installation cost increase
Solution Approach 1:
A permanent working platform is pre-installed below the switch gear platform during wind turbine manufacturing, providing ready-to-use access to electrical equipment. This preliminary action eliminates the need for temporary scaffold installation later, reducing both complexity and cost while maintaining accessibility.
2Ease of operation
If temporary scaffolding is used for service access, then accessibility is improved, but labor intensity and installation cost increase
Solution Approach 1:
The permanent working platform is designed to be self-sufficient, equipped with all necessary facilities for service personnel to access and maintain electrical equipment independently. This eliminates the need for additional temporary scaffold installation and dismantling, significantly reducing labor intensity and improving productivity.
3Ease of operation
If temporary scaffold is installed for array cable installation, then accessibility is improved, but installation time and cost increase
Solution Approach 1:
The permanent working platform is installed in advance during manufacturing, providing immediate access for array cable installation. This eliminates the time-consuming process of installing and dismantling temporary scaffolds, significantly reducing installation time and associated costs.

AI summary
A wind turbine (1), comprising a tower (4), a foundation (14), a transition piece (15), which is arranged between the tower (4) and the foundation (14) and which connects the tower (4) to the foundation (14), a platform (19), which is arranged inside the transition piece (15), a service lift (31), which can be lowered to the platform (19), and a permanent working platform (32) which is arranged below the platform (19) and in a distance (d) thereof. Due to the permanent working platform (32), the service lift (31) is easily accessible from below. The labor- and cost-intensive installation of a temporary scaffold below the platform (19) is expendable. Advantageously, the working platform (31) can also be used for array cable installation.
