Embodiment Construction

[0048] figure 1 A conventional modern upwind wind turbine 2 according to the so-called "Danish concept" is illustrated with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and three blades 10 extending radially from the hub 8 , each blade having a root end 16 closest to the hub and a blade tip 14 furthest from the hub 8 .

[0049] figure 2 A schematic diagram of an exemplary wind turbine blade 10 is shown. The wind turbine blade 10 has the shape of a conventional wind turbine blade having a root end and a tip end, and includes a root region 30 closest to the hub, a profile or airfoil region 34 furthest from the hub 8, and a The transition region 32 to the airfoil region 34 . The blade 10 includes a leading edge 18 facing the direction of rotation of the blade 10 when the blade is mounted on the hub and a trailing edge 20 facing in the opposite direction of the leading edge 18 . The airfoil region 34, also referre...

Abstract

The present invention relates to a method for installing a bulkhead in a wind turbine blade. The bulkhead comprises attachment means for attaching the bulkhead to the root end of the blade; a movement device moves the bulkhead into the installation position; the moving comprising engaging the attachment means of the bulkhead with receiving means of the root end, the receiving means being arranged and adapted to receive and hold the bulkhead by engaging with the attachment means of the bulkhead; and adhering the bulkhead to the wind turbine blade. A bulkhead for use in the method is also provided.

Description

technical field [0001] The invention relates to a spacer for a wind turbine blade and a method for installing the spacer in a wind turbine blade. Background technique [0002] Wind turbine blades are usually provided with spacers at the root end of the blade. Such spacers may be used to substantially seal the root end of the blade and, in some cases, provide a working platform at the root end of the blade. [0003] Existing methods of installing spacers are often cumbersome, requiring undesired manipulation and manipulation on the spacer in order to install the spacer. For example, some existing methods of installing spacers in the root end of wind turbine blades require temporary installation of attachment means, such as steel plates, on the spacers. The spacer is then placed at the mounting point and the attachment means attached to the root end in some temporary fashion. Then, the spacer is adhered to the wind turbine blade shell. Afterwards, the attachment means are ...
