Abstract

Palas de aerogeneradores que consisten en varios tramos o sectores unidos a través de insertos específicamente diseñados que permiten que el montaje se realice en el parque eólico al pie de Ia torre. Estos insertos están colocados tanto por el interior como por el exterior de las palas originales, en una sola pieza o en varias y unidos a las palas mediante cualquier medio mecánico, físico, de fusión de materiales (soldaduras con y sin aportación de material), o bien mediante adhesivos u otro tipo de uniones diseñadas para tal función.

Claims

REIVINDICACIONES MODIFICADAS recibidas por Ia oficina Internacional el 29 JULIO 2008 (29.07.2008)
1.- Inserto de unión de sectores de palas de aerogeneradores caracterizado por tener un perfil dentado con tuercas flotantes (5) en su interior. 2.- Inserto de unión de sectores de palas de aerogeneradores según reivindicación 1 caracterizado por estar hecho con compuestos metálicos, aleaciones, aceros, pollamldas, plásticos técnicos, materiales compuestos (composites), aluminios o mezclas de estos,
3.- Método de unión reversible de sectores de palas de aerogeneradores caracterizado porque Ia unión se realiza a partir de al menos un inserto definido en las reivindicaciones 1 y 2 en las siguientes etapas;
- deformación de la estructura del inserto (4) para hacerle perder sección y permitir su colocación en el interior de Ia pala
- colocación el inserto en el cajón interno especifico de Ia pala (6,2) - giro de Ia barra roscada (6) desde el acceso exterior (7) de los sectores de Ia pala, de forma que manipulándola en sentido contrario se consiga que ef inserto vuelva a Ia posición original.
4.- Método de unión reversible de sectores de palas de aerogeneradores según reivindicación 3 caracterizado por Ia utilización de un inserto central y al menos un inserto en uno de los extremos.
5.- Método de unión reversible de sectores de palas de aerogeneradores según reivindicación 4 caracterizado por Ia utilización de un inserto central y dos insertos en los extremos de las uniones de los sectores de las palas.
8.- Método de unión de sectores de palas de aerogeneradores según las reivindicaciones 3-5 caracterizado porque los sectores son secciones transversales de palas de aerogeneradores
