El método y la aplicación que se presentan tienen como objetivo obtener energía eléctrica a partir del oleaje. Las olas se propagan con una velocidad tal que ante una acción que les haga cambiar de velocidad de propagación liberan energía, que mediante esta invención se pretende aprovechar. La ola cambia de velocidad de propagación debido al fondo y debido a la presión del aire que la separa de la ola que va por delante. Al cambia de velocidad comprime longitudinal y progresivamente el aire atrapado entre dos olas consecutivas a lo largo del conducto. El aire una vez comprimido se conduce a una turbina que mueve un generador eléctrico, el agua también se conduce a otra turbina para generar electricidad.The method and application presented They aim to obtain electrical energy from the waves. The waves spread with a speed such that before an action that make them change propagation speed release energy, which by this invention it is intended to take advantage. The wave changes from propagation speed due to the bottom and due to the pressure of the air that separates it from the wave ahead. Al changes from speed compresses the air longitudinally and progressively caught between two consecutive waves along the duct. He once compressed air is conducted to a turbine that moves a electric generator, water is also driven to another turbine to generate electricity

El método y la aplicación que se presentan tienen como objetivo obtener energía eléctrica a partir del oleaje. Las olas se propagan con una velocidad tal que ante una acción que les haga cambiar de velocidad de propagación liberan energía, que mediante esta invención se pretende aprovechar. La ola cambia de velocidad de propagación debido al fondo y debido a la presión del aire que la separa de la ola que va por delante. Al cambiar de velocidad comprime longitudinal y progresivamente el aire atrapado entre dos olas consecutivas a lo largo del conducto. El aire una vez comprimido se conduce a una turbina que mueve un generador eléctrico, el agua también se conduce a otra turbina para generar electricidad.The method and application presented They aim to obtain electrical energy from the waves. The waves spread with a speed such that before an action that make them change propagation speed release energy, which by this invention it is intended to take advantage. The wave changes from propagation speed due to the bottom and due to the pressure of the air that separates it from the wave ahead. When changing from speed compresses the trapped air longitudinally and progressively between two consecutive waves along the duct. Air one once compressed it drives to a turbine that moves a generator electric, water is also driven to another turbine to generate electricity.

Antecedentes de la invenciónBackground of the invention

Actualmente se están explotando instalaciones que ya utilizan el oleaje para comprimir verticalmente aire. Estas instalaciones aprovechan el ascenso y descenso del agua con el oleaje dentro de un cilindro vertical, a modo de pistón con movimiento vertical, para comprimir el aire comprendido entre la superficie del agua y la turbina, que es donde se genera la electricidad.Facilities are currently being operated They already use the waves to compress air vertically. These facilities take advantage of the rise and fall of water with the swell within a vertical cylinder, as a piston with vertical movement, to compress the air between the surface of the water and the turbine, which is where the electricity.

Igualmente existen otros métodos de obtención de energía de las olas pero no están relacionados con la compresión de aire por el oleaje.There are also other methods of obtaining wave energy but are not related to the compression of air by the waves.

Descripción de la invenciónDescription of the invention

Se dispone de un conducto por el que entran las alas y aire. El aire queda atrapado entre la superficie del agua y el techo de la estructura. Las olas conducen el aire hacia la parte posterior mientras lo comprimen. La compresión se produce debido a la variación de velocidad que sufre la masa de agua que compone cada ola. Mientras la cresta de la ola no ceda a la presión, el cierre neumático no se romperá, y el aire no se escapará hacia la entrada, lográndose así la compresión, por eso se dispone de un fondo que varia la velocidad de propagación, haciendo que las olas intenten romper. Una inclinación en el techo también favorece el cierre neumático.There is a conduit through which the wings and air. The air is trapped between the surface of the water and The roof of the structure. The waves drive the air towards the part later while compressing. Compression occurs due to the variation in speed that the mass of water undergoes every wave As long as the crest of the wave does not yield to pressure, the pneumatic seal will not break, and air will not escape into the input, thus achieving compression, so there is a background that varies the speed of propagation, making the waves Try to break up A slope in the ceiling also favors the pneumatic closure

En la parte posterior del canal hay una cámara o carcasa, en la que se separa el agua del aire comprimido. La forma de la carcasa evita que las olas intenten rebotar hacia la entrada, chocando con las olas incidentes, lo que provocaría presiones que dañarían la estructura.On the back of the channel there is a camera or housing, in which the water is separated from the compressed air. The shape from the housing prevents waves from trying to bounce towards the entrance, colliding with the incident waves, which would cause pressures that They would damage the structure.

En la parte superior de dicha cámara hay un colector, para eliminar salpicaduras y conducir el aire a la turbina para aire, o dispositivo mecánico generador. En la parte inferior de dicha cámara está alojado el rodete de la turbina para agua, o dispositivo mecánico generador. Estos dos tipos de generadores soportan la presión debida a la perdida de velocidad de las olas. La invención se encuadra en el sector de energías renovables de aplicación naval y/o costera.In the upper part of said chamber there is a collector, to eliminate splashes and lead the air to the air turbine, or mechanical generating device. In the part bottom of said chamber is the turbine impeller housed for water, or mechanical generating device. These two types of generators withstand the pressure due to the loss of speed of waves. The invention is part of the energy sector Renewable naval and / or coastal application.

Descripción de una forma de realizaciónDescription of an embodiment

El puntal máximo de la apertura de entrada del conducto será del orden de la altura de ola máxima esperada, para temporal de diseño, ya que la abertura de la entrada es regulable haciendo subir o bajar el fondo para adecuarse a la mar que haya. También variando calados y trimados.The maximum prop of the entrance opening of the conduit will be of the order of the maximum expected wave height, for Temporary design, since the opening of the entrance is adjustable making raise or lower the bottom to adapt to the sea that there is. Also varying drafts and trimmings.

En la parte posterior del conducto se dispone de la cámara de separación. Encima de ella se dispondrá una conducción, con un codo para limitar salpicaduras, que llevará el gas comprimido a la turbina de aire. En la parte inferior de la cámara se sitúa el rodete de la turbina para agua. La plataforma constará de sistemas de estabilización, así como de sistemas para normalización y transporte de la electricidad propios.At the back of the duct there are The separation chamber. On top of it a driving, with an elbow to limit splashes, which will carry the compressed gas to the air turbine. At the bottom of the chamber is located the impeller of the turbine for water. The platform it will consist of stabilization systems, as well as systems for own standardization and transportation of electricity.
