Es conocida la existencia de muy diversos tipos de dispositivos queAt present, the use of wave energy is a matter in which it has not been possible to achieve optimum use of all the possibilities available to obtain a high performance of the extractor equipment.

logran extraer energia del movimiento de la superficie maritima. Sin embargo, estos dispositivos se enfrentan a un ambiente muy agresivo, por lo que las operaciones de mantenimiento y de implantation son altamente costosas e impiden la disposition de equipos complejos.They manage to extract energy from the movement of the sea surface. However, these devices face a very aggressive environment, so maintenance and implantation operations are highly expensive and prevent the disposal of complex equipment.
El titular de la presente memoria ha presentado ya con anterioridad otras solicitudes de patente que versan sobre dispositivos para aprovechamiento de energia mareomotriz, tales como el PCT/ES2012/000309 y ES2011201231.The holder of the present report has previously filed other patent applications dealing with devices for harnessing tidal energy, such as PCT / ES2012 / 000309 and ES2011201231.
La presente invention introduce como principal ventaja con respecto a las otras solicitudes, asi como a los documentos que se incluyen mas adelante como estado de la tecnica conocido el hecho de que la especial disposition del brazo extensible junto con el punto articulado de enganche de la boya en la parte inferior permite aprovechar la propia flotabilidad de la boya asi como la profundidad existente para aumentar el rendimiento del dispositivo, de manera que incluso en situaciones en las que la superficie del mar se presente rizada (situation de vientos de dos nudos), el dispositivo seguira produciendo energia.The present invention introduces as a main advantage with respect to the other applications, as well as to the documents that are included below as a known state of the art the fact that the special disposition of the extendable arm together with the articulated point of attachment of the buoy in the lower part it allows to take advantage of the buoyancy of the buoy as well as the existing depth to increase the performance of the device, so that even in situations where the sea surface is curly (situation of two knot winds), the device will continue to produce energy.
Esto demas viene acompanado por el hecho de emplear una boya de gran peso que permite generar altas presiones en los embolos para asi maximizar la obtencion de energia en el dispositivo. Dicha boya aprovecha la densidad del agua para lograr una mejora del rendimiento por encima de los dispositivos existentes en la actualidad.This is also accompanied by the use of a buoy of great weight that allows to generate high pressures in the emboli to maximize the obtaining of energy in the device. This buoy takes advantage of the density of the water to achieve an improvement of the performance over the existing devices at present.
Es conocida por parte del titular de la presente memoria la existencia de los siguientes documentos, que pueden tener cierta relation con el dispositivo que se preconiza en la presente memoria:The existence of the following documents is known by the holder of the present report, which may have a certain relationship with the device recommended herein:

La principal diferencia entre lo expuesto en esta patente y la invencion de la presente solicitud consiste en el hecho de que mientras que en la patente US2011042954 A1 la energia se obtiene a partir del movimiento ascendente y descendente de las olas exclusivamente, el dispositivo que se preconiza en esta memoria es capaz de obtener energia aprovechando la profundidad a la que esta sumergida la boya para comprimir a altas presiones el liquido hidraulico que acciona el altemador, de modo que pequenas olas son asi capaces de generar energia.The main difference between what is stated in this patent and the invention of the present application consists in the fact that while in US2011042954 A1 the energy is obtained from the upward and downward movement of the waves exclusively, the device that is recommended in this memory it is able to obtain energy by taking advantage of the depth at which the buoy is submerged to compress at high pressures the hydraulic liquid that drives the disruptor, so that small waves are thus capable of generating energy.
- ES 2148105 Bl. Planta para el aprovechamiento de la energia motriz del mar (Perez Rodriguez, Jose Abel; Diaz Hernandez Pedro; 01/12/1998). Consiste esta invencion en una planta formada por una bomba vertical anclada al fondo del mar, que es actuada mediante flotador unido a un embolo para impulsar el agua a traves de unas tuberias de presion hasta un acumulador, de donde pasa a una turbina que mueve un generador electrico. Estando la bomba formada por dos tubos coaxiales deslizante uno en el interior del otro, actuando el interior como embolo unido a una boya en superficie que le transmite el movimiento, mientras el extemo estara anclado al fondo y mantenido en position vertical por flotadores alojados en su extremo superior, con lo que el movimiento de las olas actua dicha bomba para el movimiento de la planta.- ES 2148105 Bl. Plant for the use of the motive energy of the sea (Perez Rodriguez, Jose Abel; Diaz Hernandez Pedro; 12/01/1998). This invention consists of a plant formed by a vertical pump anchored to the bottom of the sea, which is actuated by means of a float attached to a plunger to drive the water through pressure pipes to an accumulator, from where it passes to a turbine that moves a Electric generator. The pump being formed by two coaxial tubes sliding one inside the other, the interior acting as a pin attached to a surface buoy that transmits the movement, while the outside will be anchored to the bottom and held vertically by floats housed in its upper end, so that the movement of the waves acts said pump for the movement of the plant.
Esta invencion adolece de la limitation de que se unicamente desarrolla presion en los embolos segun la capacidad de flotation de la boya, generando energia en la subida de esta. No se aprovecha al maximo el peso de esta para aprovechar los movimientos descendentesThis invention suffers from the limitation that pressure is only developed on the emboli according to the buoyancy's buoyancy, generating energy in its rise. The weight of this is not used to the maximum to take advantage of the downward movements

- ES 2 104 181. Dispositivo para un aparato de energla de olas basado en una boya. Torger Tveter; 09/10/1992). Se trata de un dispositivo formado por una boya que esta conectada a un piston el cual a su vez queda anclado al fondo marino. Dicho piston posee valvulas de entrada y salida del agua que permiten su impulsion aprovechando el movimiento de subida y bajada transmitido a la boya por las olas y mareas. Este dispositivo funciona asociado a una o varias darsenas donde se acumula el agua impulsada, reservando la energia almacenada para ser aprovechada en momentos de baja production.- EN 2 104 181. Device for a wave energy device based on a buoy. Torger Tveter; 10/09/1992). It is a device formed by a buoy that is connected to a piston which in turn is anchored to the seabed. Said piston has water inlet and outlet valves that allow its impulsion taking advantage of the up and down movement transmitted to the buoy by waves and tides. This device works associated to one or several darsenas where the driven water accumulates, reserving the stored energy to be used in times of low production.
La invencion objeto de la presente memoria presenta semejanzas con la citada en el hecho de emplear uno o varios cilindros con sus respectivos pistones y la valvuleria asociada. El rendimiento obtenido con este dispositivo sera bastante inferior debido a que unicamente emplea un conducto para el transporte del agua, haciendose necesario esperar a cada ciclo de marea para poder regular el caudal de transporte de agua y, por tanto, la cantidad de energia a producir.The invention object of the present report presents similarities with that mentioned in the fact of using one or several cylinders with their respective pistons and the associated valve. The performance obtained with this device will be much lower because it only uses a conduit for the transport of water, making it necessary to wait for each tidal cycle to be able to regulate the flow of water transport and, therefore, the amount of energy to be produced .
Por todo lo indicado, no es conocida por parte del titular de la presente memoria la existencia de ningun dispositivo que offezca las prestaciones descritas y que disponga de un mecanismo de funcionamiento similar, por lo que la invencion se configura como una evidente novedad. En base a esto, se solicita la correspondiente protection offecida a este tipo de invenciones.For all the above, it is not known by the owner of the present report the existence of any device that offers the described benefits and that has a similar operating mechanism, so the invention is configured as an obvious novelty. Based on this, the corresponding protection of this type of invention is requested.

brazo largo dispone en su extremo de una boya que se mueve gracias a la accion del agua mientras que en el extremo del brazo corto se dispone el mecanismo que permite bombear el liquido hidraulico y producir la energia. La base con el citado eje de giro se dispone en una superficie fija, que podra ser bien el suelo en una zona proxima al mar o bien una plataforma flotante.Long arm has at its end a buoy that moves thanks to the action of water while at the end of the short arm there is a mechanism that allows to pump the hydraulic fluid and produce energy. The base with the aforementioned axis of rotation is arranged on a fixed surface, which could be either the ground in an area near the sea or a floating platform.
Con el fin de ajustarse a las cambiantes condiciones de oleaje del mar y a las diferentes alturas de la marea que en cada momento pueda haber, el brazo largo de la maquina sera extensible, estando compuesto por dos o mas tramos telescopicos que pueden ensamblarse en distintas posiciones segun sea necesario, permitiendo de este modo modificar la longitud de dicho brazo largo. Asimismo, la conexion del brazo largo con la boya (o las boyas, en su caso) que genera la fuerza que mueve el conjunto es realizada mediante una viga cuyo eje es perpendicular al brazo, en cuyo extremo inferior se dispone la boya. La conexion entre las vigas perpendiculares es movil, de manera que es posible regular la altura a la que la boya estara dispuesta con respecto al eje de giro del conjunto.In order to adjust to the changing sea swell conditions and the different heights of the tide that may exist at any time, the long arm of the machine will be extensible, being composed of two or more telescopic sections that can be assembled in different positions as necessary, thereby allowing the length of said long arm to be modified. Likewise, the connection of the long arm with the buoy (or the buoys, if applicable) that generates the force that moves the assembly is made by a beam whose axis is perpendicular to the arm, at whose lower end the buoy is arranged. The connection between the perpendicular beams is mobile, so that it is possible to adjust the height at which the buoy will be arranged with respect to the axis of rotation of the assembly.
La altura a la que se dispondra la viga perpendicular al brazo largo vendra determinada por el maximo recorrido que pueda realizar el brazo corto, el cual determina el punto mas alto y mas bajo que debe alcanzar la boya. En funcion de las condiciones de oleaje y marea se regulara la longitud del brazo largo y la altura de la viga perpendicular al brazo para asegurar que no se supera el limite de recorrido.The height at which the beam perpendicular to the long arm will be arranged will be determined by the maximum path that the short arm can make, which determines the highest and lowest point the buoy must reach. Depending on the wave and tide conditions, the length of the long arm and the height of the beam perpendicular to the arm will be regulated to ensure that the travel limit is not exceeded.
La boya se configura como un contenedor hueco cerrado que dispone de apertura de admision de agua asi como un mecanismo de vaciado, de manera que tambien se posibilita el variar a voluntad el peso de la boya mediante la variacion de la cantidad de agua de su interior. El presente dispositivo podra incorporar diferentes tipos de boyas, para maximizar la obtencion de energia en funcion de las condiciones del entomo donde se emplace. La posibilidad de llenado y vaciado de la boya permitira variar la densidad de esta de modo que dicho valor se situe por encima o por debajo del valor de la densidad del agua, de modo que se logre obtener el peso necesario para hundir la boya o la flotabilidad necesaria paraThe buoy is configured as a closed hollow container that has a water inlet opening as well as an emptying mechanism, so that it is also possible to vary the weight of the buoy at will by varying the amount of water inside . The present device may incorporate different types of buoys, to maximize the obtaining of energy depending on the conditions of the environment where it is used. The possibility of filling and emptying the buoy will allow the density of the buoy to be varied so that said value is located above or below the water density value, so that the weight necessary to sink the buoy or the buoyancy needed to

La conexion de la viga vertical con la boya sera articulada, y se realizara en el punto mas bajo de esta, siempre por debajo del centro de gravedad de la boya, teniendo en cuenta que dicho punto cambia de position en funcion de la cantidad de agua que contenga en cada momento. De este modo garantizamos que la fuerza ascendente que provoca la flotabilidad de la boya no haga girar esta en ningun momento.The connection of the vertical beam with the buoy will be articulated, and will be made at the lowest point of the buoy, always below the center of gravity of the buoy, taking into account that said point changes position depending on the amount of water that contains in every moment. In this way we guarantee that the upward force caused by the buoyancy of the buoy does not spin at any time.
El accionamiento del mecanismo recolector de energia se realiza a traves de unos embolos conectados al extremo del brazo corto y a la base del dispositivo. Conforme el extremo del brazo se mueva accionara los embolos, los cuales impulsaran liquido hidraulico hacia un generador de energia, que podra ser una turbina, un altemador o cualquier otro tipo de dispositivo valido para estas fimcionesThe activation of the energy collection mechanism is carried out through emboli connected to the end of the short arm and to the base of the device. As the end of the arm moves, it will trigger the emboli, which will drive hydraulic fluid towards an energy generator, which could be a turbine, an alterator or any other type of device valid for these functions.
Tal y como se ha comentado, los ciguenales son accionados por el movimiento de unas boyas dispuestas en el perimetro de la plataforma. De cada una de estas boyas saldra una pareja de brazos dispuestos en paralelo los cuales conectan con los ciguenales citados. El movimiento ascendente y descendente de las boyas actuara sobre el cigiienal provocando un giro parcial de este, provocando a su vez dicho giro que por medio de las bielas se accione una o varias parejas de pistones, comprimiendo liquido hidraulico uno y expandiendo el volumen de la camara el otro. El punto muerto de cada piston que conforma una pareja estara en el punto medio del cilindro. La velocidad media de la ola en el lugar de emplazamiento del dispositivo determinara el caudal de liquido hidraulico que sera bombeado, dato que sera clave para el dimensionamiento de embolos y conducciones.As mentioned, the crankshafts are driven by the movement of buoys arranged on the perimeter of the platform. From each of these buoys a pair of arms arranged in parallel will come out which connect with the crankshafts mentioned. The upward and downward movement of the buoys will act on the crankshaft causing a partial rotation of the crank, which in turn causes that one or more pairs of pistons be activated by connecting the cranks, compressing one hydraulic fluid and expanding the volume of the the other one The dead center of each piston that forms a pair will be at the midpoint of the cylinder. The average speed of the wave at the location of the device will determine the flow of hydraulic fluid that will be pumped, which will be key to the dimensioning of emboli and pipes.
Ademas de generar energia a traves del movimiento de las olas, el presente dispositivo estara capacitado para generar energia mediante el aprovechamiento de la flotabilidad de la boya. Mediante el llenado de agua de la boya o laIn addition to generating energy through the movement of the waves, the present device will be able to generate energy by exploiting the buoyancy of the buoy. By filling buoy water or the

incorporation de un contrapeso se aumentara su peso para facilitar el hundimiento partial. El peso inicial de la boya (o boyas) sera tal que permita generar altas presiones en los embolos, haciendo que baje el conjunto y se muevan los brazos del dispositivo. De esta manera se establece un mecanismo de obtencion de energla que permitira generar energia intiuso con el mar en practicamente en calma, y que al mismo tiempo tambien funcionara en presencia de oleaje maximo.incorporation of a counterweight will increase its weight to facilitate partial sinking. The initial weight of the buoy (or buoys) will be such that it allows to generate high pressures in the emboli, causing the assembly to lower and the arms of the device to move. In this way, a mechanism for obtaining energy is established that will allow generating intiuso energy with the sea in practically calm, and that at the same time will also work in the presence of maximum waves.
En situaciones de poca profundidad, donde el movimiento de los brazos se ve restringido por la proximidad del fondo, sera conveniente disponer una boya de diametro maximo o bien varias boyas, mientras que en caso de que se disponga de suficiente profundidad se obtendria un mayor aprovechamiento de la energia mediante la disposition de una boya de menor diametro y con mayor peso. Una ventaja anadida del presente dispositivo consiste en el hecho de que gracias a su especial configuration resulta sencilla la operation de cambiar la boya y sustituirla por otra que se adapte a la situation mas optima en cada momento.In shallow situations, where the movement of the arms is restricted by the proximity of the bottom, it will be convenient to have a maximum diameter buoy or several buoys, while if sufficient depth is available, greater use would be obtained of the energy by means of the disposition of a buoy of smaller diameter and with greater weight. An added advantage of the present device consists in the fact that thanks to its special configuration it is easy to change the buoy and replace it with another that adapts to the most optimal situation at all times.

La boya (1) estara configurada como un deposito hueco cerrado el cual dispondra de un mecanismo automatico de admision y expulsion de agua de modo que se pueda variar a voluntad el peso total de esta. Cuanto mayor sea el peso de la boya (1), mayor presion se generara en los embolos (4) y mayor sera la cantidad de energia que se obtendra del movimiento de la ola. Dicho peso sera sostenido por la densidad del agua.The buoy (1) will be configured as a closed hollow tank which will have an automatic water intake and expulsion mechanism so that the total weight of the water can be varied at will. The greater the weight of the buoy (1), the greater pressure will be generated in the emboli (4) and the greater the amount of energy that will be obtained from the movement of the wave. Said weight will be sustained by the density of the water.
El brazo largo (3) dispondra a cada lado de unos amortiguadores (33) que absorben cualquier esfuerzo lateral accidental que pudiera actuar sobre las vigas que conforman el brazo, tales como la action del viento u otras causas no previstas.The long arm (3) will have on each side some shock absorbers (33) that absorb any accidental lateral effort that could act on the beams that make up the arm, such as the action of the wind or other unforeseen causes.
Los embolos (4) anclados al bastidor (9) estaran unidos en su otro extremo al extremo del brazo corto (35), y con el movimiento de este se veran accionados altemativamente, al haberse dispuesto tanto en la parte superior del recorrido del extremo del brazo corto (35) como en la parte inferior.The plungers (4) anchored to the frame (9) will be attached at their other end to the end of the short arm (35), and with the movement of the latter they will be actuated alteratively, having been arranged both at the top of the end of the end short arm (35) as in the lower part.
Dichos embolos (4) estaran conectados a un deposito de almacenamiento (5), e iran impulsando liquido hidraulico hacia este. Dichos embolos tambien estaran conectados a un tanque de impulsion (6) que permite la introduction de liquido hidraulico hacia los embolos (4) para el caso en el que se desee accionar estos para mover la boya (1).Said emboli (4) will be connected to a storage tank (5), and will drive hydraulic fluid towards it. Said embolos will also be connected to a supply tank (6) that allows the introduction of hydraulic fluid towards the emboses (4) for the case in which it is desired to operate these to move the buoy (1).
El tanque de impulsion (6) estara conectado a un motor hidraulico conectado a un generador electrico (7) que producira energia conforme vaya siendo actuado desde dicho tanque.The discharge tank (6) will be connected to a hydraulic motor connected to an electric generator (7) that will produce energy as it is operated from said tank.
