Abstract

The invention relates to a system for generating electricity using sea swell. The inventive system comprises a resonance chamber having a water inlet and a water outlet in the form of two parallel horizontal conduits which project out towards the front and which are provided with unidirectional valves, by means of which water enters the chamber alternately. For this purpose, the swell enters the chamber and, when the external pressure exerted by the swell on the inlet ceases, the water deposited in said chamber is released. In this way, the passage of an alternating current is enabled which causes the blades of a turbine to rotate and in turn drives an electricity generator in any type of pump system or any motor mechanism. The inventive system can be installed on a wave breaker, a needle, a bluff or any similar coastal location that experiences a strong swell.

ESTADO DE LA TÉCNICASTATE OF THE TECHNIQUE

SISTEMAS DE GENERACIÓN DE ELECTRICIDAD POR OLEAJE MARINOMARINE SWELL ELECTRICITY GENERATION SYSTEMS
Es un novedoso sistema de bombeo formado básicamente por los componentes que aquí describo cuya funciones particulares y asociadas se combinan con la acción y condiciones de los elementos y fuerzas naturales referidas a continuación.It is a novel pumping system basically formed by the components that I describe here whose particular and associated functions are combined with the action and conditions of the elements and natural forces referred to below.
Una cámara (1 ) construida dentro de un bordo, farallón, risco, en el terraplén de un rompeolas (Fig. 2), o lugar similar en la costa donde choca un fuerte ímpetu de oleaje.A chamber (1) built inside a board, cliff, cliff, on the embankment of a breakwater (Fig. 2), or similar place on the coast where a strong wave momentum collides.
En la pared interna (11 ) de la cámara (1 ) antes del fondo, hay dos conductos o tubos (2, 3) que se proyectan hacia el frente horizontales paralelos para atravesar y salir por la ladera (9) o pared frente al embate de las olas; una de los conductos o tubos (2) es para la entrada de agua y el otro conducto (3) paralelo es para el vaciado o salida.On the inner wall (11) of the chamber (1) before the bottom, there are two conduits or tubes (2, 3) that project towards the front horizontal parallel to cross and exit the slope (9) or wall facing the ram wave; one of the ducts or tubes (2) is for the water inlet and the other parallel duct (3) is for emptying or exiting.
Cada una de los conductos o tubos (2, 3) horizontales tiene compuertas, dispositivos o válvulas (4, 5) tipo check que permiten el flujo de agua en un solo sentido.Each of the horizontal ducts or tubes (2, 3) has gates, devices or valves (4, 5) type check that allow the flow of water in one direction only.
Una turbina (6) se instala entre el espacio que separa los conductos o tubos (2, 3) horizontales, de tal manera que el eje vertical (13) de la turbina (6) quede al centro y sus aspas giren dentro de cada uno de los conductos (2, 3) cuando el agua fluya por cualquiera de los dos tubos o conductos (2, 3). La cámara (1 ) puede estar cerrada por un techo total o parcial, fijo o removible y en la cubierta puede tener aberturas (7) para respiración.A turbine (6) is installed between the space that separates the horizontal ducts or tubes (2, 3), so that the vertical axis (13) of the turbine (6) is at the center and its blades rotate inside each of the ducts (2, 3) when water flows through either of the two tubes or ducts (2, 3). The chamber (1) can be closed by a total or partial roof, fixed or removable and on the cover it can have openings (7) for breathing.
Para abarcar una mayor cantidad de agua, los conductos de entrada y salida pueden tener forma cónica o piramidal, o bien, la boca de entrada de los conductos o tubos (2, 3) puede ser más ancha, o en forma de embudoTo cover a greater amount of water, the inlet and outlet ducts can have a conical or pyramidal shape, or the inlet of the ducts or tubes (2, 3) can be wider, or funnel-shaped
La turbina (6) puede ser de cualquier tipo y operar con su eje en sentido vertical en medio de dos conductos o tubos (2 y 3 de Fig. 1 y Fig. 2), o puede ser de eje horizontal (16 de Fig. 3) operando una turbina para cada tubo o conducto .The turbine (6) can be of any type and operate with its axis vertically in the middle of two ducts or tubes (2 and 3 of Fig. 1 and Fig. 2), or it can be of horizontal axis (16 of Fig. 3) operating a turbine for each tube or conduit.
El funcionamiento del sistema de cámara para generador de electricidad por oleaje, es el siguiente:The operation of the wave generator camera system is as follows:
Las conductos o tubos (2, 3) horizontales del sistema pueden quedar a una altura media con respecto a oleaje habitual del lugar donde se instale.The horizontal ducts or tubes (2, 3) of the system can be at an average height with respect to the usual swell of the place where it is installed.
Las válvulas check (4, 5) o dispositivos que permiten el flujo en un solo sentido, estarán sincronizadas de tal manera que una válvula o compuerta se abre para permitir el paso de agua por un conducto o tubo mientras la válvula check en el otro conducto o tubo permanece cerrada, y viceversa.Check valves (4, 5) or devices that allow one-way flow will be synchronized in such a way that a valve or gate opens to allow water to pass through a conduit or tube while the check valve in the other conduit or tube remains closed, and vice versa.
Durante el tiempo de empuje de la ola contra el conducto o tubo (2), entra una porción de agua presionando para vencer la resistencia de la válvula check (4) que permite fluir el agua hacia adentro haciendo girar a la turbina (6); el agua recolectada dentro del depósito (1 ) se acumula y alcanza un nivel alto dentro de la cámara(1 ); mientras tanto, el otro tubo o conducto (3) de salida permanece cerrada por la acción de su válvula check (5). Cuando disminuye o cesa la presión exterior del oleaje sobre la entrada (2), su válvula check (4) se cierra, al tiempo que la válvula check (5) en el otro conducto o tubo (3) de salida se abre para dejar salir el agua almacenada cuyo flujo también hace girar a la turbina (6).During the time of pushing the wave against the duct or tube (2), a portion of water enters by pressing to overcome the resistance of the check valve (4) that allows the water to flow in by spinning the turbine (6); the water collected inside the tank (1) accumulates and reaches a high level inside the chamber (1); Meanwhile, the other outlet tube (3) remains closed by the action of its check valve (5). When the external pressure of the waves on the inlet (2) decreases or ceases, its check valve (4) closes, while the check valve (5) in the other outlet pipe (3) opens to let out the stored water whose flow also rotates the turbine (6).
En un diseño de turbina con eje vertical (Fig. 2) tanto el flujo de agua por el conducto de entrada (2) como el flujo por el conducto de salida (3) hacen girar en el mismo sentido alternadamente a la turbina (6) cuyo eje transmite la rotación a un generador eléctrico, a un sistema de bombeo o se aplica a alguna otra función mecánica o motriz.In a turbine design with vertical axis (Fig. 2) both the flow of water through the inlet duct (2) and the flow through the outlet duct (3) rotate the turbine in the same direction alternately (6) whose axis transmits rotation to an electric generator, to a pumping system or is applied to some other mechanical or motor function.
En un diseño de turbinas con eje horizontal que se ilustra en Fig. 3, el flujo del agua por el conducto de entrada (2) es impulsado en un sentido mientras que la turbina horizontal en el conducto de salida (3) gira en el otro sentido. Para que ambas corrientes, de entrada y de salida, impulsen a una turbina horizontal en un solo sentido, se puede poner los conductos (2, 3) uno encima del otro de modo que la corriente de entrada (2) fluya impulsando a las aspas por la mitad superior (2) mientras que la corriente de salida fluya impulsando a las aspas por el conducto de abajo (3). In a horizontal axis turbine design illustrated in Fig. 3, the flow of water through the inlet duct (2) is driven in one direction while the horizontal turbine in the outlet duct (3) rotates in the other sense. So that both inlet and outlet streams drive a horizontal turbine in only one direction, the ducts (2, 3) can be placed on top of each other so that the inlet stream (2) flows by driving the blades in the upper half (2) while the output current flows by driving the blades through the duct below (3).
