AI Technical Summary

Benefits of technology

The present invention provides a holding arrangement for blades that allows for stable transportation. By attaching the center frame to the center section for holding the blade, a bending of the blade during transportation due to its own weight is reduced. This results in a more stable and comfortable transportation of the blades. The invention also allows for efficient curved blade transportation and stacking arrangement, with a reduced total length of a curved blade stack due to applying the arrangement for supporting the curved blades at the center sections. Additionally, a blade tip protection and damping means may be attached to the tip end for stabilizing the tip end during transportation.

Problems solved by technology

Pre-bended or curved blades take up more space than straight blades so that curved blades makes it difficult to utilize the space when stacking the blades during transportation.

Embodiment Construction

[0044]The illustrations in the drawings are schematical. It is noted that in different figures, similar or identical elements are provided with the same reference signs.

[0045]FIG. 1 shows an arrangement 100 for holding blades, in particular curved blades, for a wind turbine. The arrangement 100 comprises a first end frame 110 for holding a first root end 102 of a first blade 101. Furthermore, the arrangement 100 comprises a first center frame 111 for holding a first center section 103 of the first blade 101. The first end frame 110 is formed for being coupled to a supporting base 120. The first end frame 110 comprises a bracket or other fixing means for fixing and holding the first root end 102 of the first blade 101.

[0046]The first center frame 111 comprises a U-shaped profile which comprises an open side 212 (see FIG. 2) through which the first blade 101 is insertable. The first center frame 111 is coupleable to the supporting base 120.

Abstract

An arrangement is provided for holding blades for a wind turbine. The arrangement includes a first end frame and a first centre frame. The first end frame is configured for holding a first root end of a first blade. The first end frame is formed for being coupled to a supporting base. The first centre frame is configured for holding a first centre section of the first blade in such a way that the first centre section is spaced from a first tip end of the first blade. The first centre frame is formed for being coupled to the supporting base.

Description

[0001]The present application claims priority to European Patent Office application No. 12170512.3 EP filed Jun. 1, 2013, the entire content of which is hereby incorporated herein by reference.FIELD OF INVENTION [0002]The present invention relates to an arrangement for holding blades, in particular curved blades, for a wind turbine. Furthermore, the present invention relates to a transporting system for transporting blades, in particular for curved blades, for a wind turbine. Moreover, the present invention relates to a method of holding blades, in particular curved blades, for a wind turbine.BACKGROUND OF INVENTION [0003]In modern wind turbines, wind turbine blades are pre-bended or curved in order to increase the aerodynamic efficiency. Pre-bended or curved blades take up more space than straight blades so that curved blades makes it difficult to utilize the space when stacking the blades during transportation.[0004]U.S. Pat. No. 6,983,844 B2 discloses a method for transporting a ...
