Title:
WIND TURBINE FRAME WITH FLEXIBLE COUPLING
Document Type and Number:
Japanese Patent JP2023156245
Kind Code:
A
Abstract:
To reduce the magnitude of deformations transmitted from a primary frame to a secondary structure.SOLUTION: A wind turbine (10) comprises a wind turbine tower (15), and a nacelle including a main frame (110), where the main frame is connected to the tower (15), and further comprises a secondary structure (120) connected to the main frame (110), and flexible couplings (130) between the main frame (110) and the secondary structure (120) that are configured to reduce transmission of deformations from the main frame (110) to the secondary structure (120). The present disclosure also relates to secondary structures (120) configured to be connected to primary frames (110), and to methods (500) for refurbishing a secondary structure (120) of a wind turbine (10).SELECTED DRAWING: Figure 3
