Abstract

<p>Dispositivo para la conversión de energía de las olas en energía eléctrica y procedimiento para su despliegue en la ubicación de aprovechamiento, en los que el dispositivo comprende una construcción (50) de soporte, que se compone de elementos (52) de flotabilidad y que tiene un tubo (51) de soporte<br /> conectado en el lado superior. El dispositivo comprende un engranaje (30) de articulación en la circunferencia interior conectado con la superficie exterior del tubo (51) de soporte de manera deslizante y una esfera (32) a la que se conecta de manera pivotante el cuerpo (20) flotante. El dispositivo tiene dos engranajes, el primer engranaje (1) flexible para conectar el cuerpo (20) flotante al segundo engranaje y el segundo engranaje para conectar el engranaje (1) flexible al generador. El engranaje (1) flexible consiste en poleas (6a, 6b, 6c) y un elemento flexible, por ejemplo, una cuerda o un cable de acero y el segundo engranaje puede disponerse de diversas formas adecuadas, por ejemplo, elementos rígidos como un conjunto de un engranaje (4) y una cremallera (2) colocados en el interior del tubo (53) de soporte inferior o un elemento flexible, por ejemplo, una cadena (3) y una rueda (5) dentada dispuestas en el elemento (52) de flotabilidad. La construcción (50) de soporte se conecta mediante cuerdas (63) al peso (67) de soporte que está realizado en forma de un segmento de esfera o bien directamente o bien a través de los elementos de rodamiento colocados en la indentación esférica de la base (61) de anclaje. La invención comprende el procedimiento para el despliegue del dispositivo en la ubicación de aprovechamiento, lo que es particularmente adecuado debido al transporte estable con bajo calado.</p>
