Tower part for a wind turbine, an aperture cover system, a method for manufacturing a tower part and uses hereof

摘要

The invention relates to a tower part for a wind turbine including at least one wall segment and at least one aperture segment including at least one aperture. The wall segment and the aperture segment are connected and the aperture segment is of a substantially uniform thickness and is thicker than the thickness of the wall segment. The invention further related to an aperture cover system for covering at least one aperture in a tower part for a wind turbine including cover plates and attachments for attaching the system to the tower part, wherein the attachments do not affect the fatigue limit of the tower part. Finally, the invention relates to a method for manufacturing a wind turbine tower part and uses thereof.

主权项

1. A method for manufacturing a wind turbine tower part comprising an aperture segment and a wall segment, the method comprising:
forming the wall segment as less than a full 360° ring; forming an aperture in the aperture segment; forming the aperture segment with a substantially uniform thickness that is thicker than a thickness of the wall segment; fixating one of the wall segment or the aperture segment in a fixating unit; moving the other of the wall segment or the aperture segment to a position in proximity of the one in the fixating unit; and connecting the wall segment and the aperture segment to produce a full 360° ring.
