La central eléctrica de la presente invención está colocada en el mar en una posición parcialmente sumergida y genera energía eléctrica a partir del movimiento de las olas. The power plant of the present invention is placed in the sea in a partially submerged position and generates electrical energy from the movement of the waves.
Esta unidad 1 está formada por una columna 2 que es hueca y a lo largo de la cual se desplaza exteriormente al menos un flotador 10 por el movimiento de las olas. Dicho flotador 10 está guiado mediante unas guías 7 colocadas longitudinalmente en el exterior de dicha columna. Para facilitar dicho guiado, el flotador 10 comprende en su parte superior una rueda 9 que se acopla con una de dichas guías 7. Dicha columna 2 comprende en su interior los componentes de generación de energía eléctrica, tal como un generador de energía 4 y una caja de engranajes 13. Dicho generador de energía 4 está conectado a un control electrónico 8. This unit 1 is formed by a column 2 that is hollow and along which at least one float 10 is displaced externally by the movement of the waves. Said float 10 is guided by guides 7 placed longitudinally on the outside of said column. To facilitate said guidance, the float 10 comprises in its upper part a wheel 9 that engages with one of said guides 7. Said column 2 comprises inside the electric power generation components, such as a power generator 4 and a gearbox 13. Said power generator 4 is connected to an electronic control 8.

The translational movement of said float is transmitted to the power generator 16 is carried out by an external maroma 6 that is placed externally in said column 2 and an internal maroma 14 placed inside the column 2.
Dicha maroma externa 6 está unida en un extremo a una rueda sumergida 18 y en su otro extremo pasa por una polea 12 situada cercana al extremo superior de la columna 2. Por su parte, un extremo dicha maroma interna 14 se define en dicha polea 12 y está unida en su otro extremo a una rueda tractora 19, que está conectada a dicha caja de engranajes 13. Said external maroma 6 is attached at one end to a submerged wheel 18 and at its other end it passes through a pulley 12 located near the upper end of the column 2. On the other hand, an end said internal maroma 14 is defined in said pulley 12 and is connected at its other end to a tractor wheel 19, which is connected to said gearbox 13.

En la parte inferior de la columna 2 hay una cámara de agua 3, que se utiliza para su inundación cuando la unidad se debe situar en el fondo del mar, por ejemplo, para escapar de un temporal. El agua de inundación entra por una abertura 5, evacuando el aire para una posterior recuperación a una cámara de aire 1 1 , por donde se expulsará el agua cuando se libere para emerger. At the bottom of column 2 there is a water chamber 3, which is used for flooding when the unit must be placed at the bottom of the sea, for example, to escape a storm. The flood water enters through an opening 5, evacuating the air for later recovery to an air chamber 1 1, where the water will be expelled when released to emerge.
La producción de energía se conseguirá de la siguiente manera: El o los flotadores 10, al deslizarse en ambos sentidos a lo largo de la columna 2, arrastran la maroma externa 6 desde el punto de unión inferior del flotador 10, pasando por la rueda sumergida 18, y retornando a un cabrestante 17 situado junto a dicha polea 12. Energy production will be achieved in the following manner: The float (s) 10, when sliding in both directions along the column 2, drag the external maroma 6 from the lower attachment point of the float 10, passing through the submerged wheel 18, and returning to a winch 17 located next to said pulley 12.
Este movimiento del flotador 10 hace girar el eje 15 estanco, que está enlazado con la polea 12, que transmite la energía de rotación a la rueda tractora 19 mediante la maroma interna 14. Esta rueda tractora 19 transmite la energía de rotación al generador de energía 16 mediante la caja de engranajes 13. Debe indicarse que la columna 2 puede comprender en su parte superior 20 una escotilla 20 para permitir el acceso a su interior, por ejemplo, para facilitar las tareas de mantenimiento de la unidad 1 de generación de energía eléctrica. En la figura 2 se representa una posible disposición de una pluralidad de unidadesThis movement of the float 10 rotates the sealed shaft 15, which is linked to the pulley 12, which transmits the rotation energy to the tractor wheel 19 by means of the internal lens 14. This tractor wheel 19 transmits the rotation energy to the power generator. 16 using the gearbox 13. It should be noted that column 2 may comprise in its upper part 20 a hatch 20 to allow access to its interior, for example, to facilitate the maintenance tasks of the electric power generation unit 1.
