Embodiment Construction

[0050] The invention will now be described in detail with reference to the accompanying drawings showing an embodiment of a root insert according to the invention and an embodiment of a wind turbine blade root comprising a plurality of such root inserts of the invention.

[0051] First, refer to figure 1 and figure 2 , which show a perspective view of a root insert 10 for a wind turbine blade root from two opposite sides and two opposite ends respectively, image 3 and Figure 4 show respectively figure 1 Two mutually perpendicular cross-sectional views of the insert.

[0052] The root insert 10 includes an enlarged connecting portion 12 at a proximal end 18 of the root insert 10 and a flattened wedge portion 16 at a distal end 14 of the root insert 10 . The enlarged connecting portion 12 extends transversely with respect to a longitudinal axis extending between the proximal end 18 and the distal end 14 to provide a substantial width in a direction perpendicular to the long...

Abstract

The invention relates to an insertion piece for a wind turbine blade root. The insertion piece comprises a wedge-shaped part which is lengthwise and extends between the far end and the near end of the insertion piece, and the wedge-shaped part has two opposite main surfaces; and the thickness of the wedge-shaped part increases between the opposite main surfaces along the direction from the far end to the near end. The insertion piece also comprises a connecting part for assembling the insertion piece in a mounting piece, wherein the connecting part and the wedge-shaped part are connected into a whole, and the connecting part is positioned at the near end of the wedge-shaped part. By utilizing the insertion piece, the total weight of the assembled wind turbine blade and the cost of raw materials can be obviously reduced. The invention also discloses the wind turbine blade root comprising a plurality of the insertion pieces, and a manufacturing method of the wind turbine blade root.

Description

technical field [0001] The invention relates to an insert for a wind turbine blade root, a wind blade root and a method of manufacturing a wind blade root. Background technique [0002] Throughout the history of wind turbine blade production, various efforts have been made to develop a strong, compact and inexpensive root insert. It has been difficult to secure fiberglass / resin, wood fiber / resin or carbon fiber / resin composite structures to steel mandrels in an efficient and reliable manner. [0003] Until now, root insert constructions and installation methods used in the industry have fallen into one of two categories. [0004] The first type is represented by the following patent publications: US7,163,378B2; WO2004 / 110862A1; EP1486415A1 and US4,420,354A. [0005] In these patent specifications, a substantially circular metal insert is adhesively incorporated into the blade root by one measure or another. Load transfer is achieved by mobilizing shear in the bonding adhe...
