Description

GENERADOR DE ENERGÍA ELÉCTRICA  ELECTRICAL POWER GENERATOR
DESCRIPCIÓN DESCRIPTION
La presente invención hace referencia a un dispositivo generador de energía eléctrica mediante la transformación de la energía proveniente de olas en energía rotacional y posteriormente en energía eléctrica.  The present invention refers to an electric power generating device by transforming energy from waves into rotational energy and subsequently into electrical energy.
Actualmente, se conocen dispositivos para la generación de energía eléctrica a partir de la energía proveniente de las olas, por ejemplo, el documento GB2192671 da a conocer un sistema para la generación de energía eléctrica a partir de la energía proveniente de las olas mediante un sistema peso-contrapeso o un sistema del tipo manivela.  Currently, devices for generating electricity from waves are known, for example, GB2192671 discloses a system for generating electricity from waves coming from waves using a system weight-counterweight or a crank type system.
El sistema propuesto por dicho documento utiliza un flotador unido por medios de una cuerda a un contrapeso, dicho conjunto flotador-contrapeso se conecta a una polea doble de modo que se garantice que el contrapeso mantiene la tensión de la cuerda cuando el flotador se desplaza desde la cresta de una ola hacia el valle. Para que éste sistema funcione, dicha doble polea debe contar con un sistema para que las poleas giren realizando fuerza sobre el eje en un solo sentido mientras que en el otro sentido deben girar libremente, ya que el contrapeso no ejerce una fuerza suficiente para hacer rotar el eje.  The system proposed by said document uses a float connected by means of a rope to a counterweight, said float-counterweight assembly is connected to a double pulley so as to ensure that the counterweight maintains the tension of the rope when the float moves from the crest of a wave towards the valley. For this system to work, said double pulley must have a system for the pulleys to rotate by exerting force on the shaft in one direction while in the other direction they must turn freely, since the counterweight does not exert sufficient force to rotate the axis.
El mantenimiento de este tipo de sistema se hace complejo dado que las partes móviles, tales como el contrapeso y poleas especiales requieren un mantenimiento para asegurar el correcto funcionamiento del generador.  The maintenance of this type of system becomes complex since the moving parts, such as the counterweight and special pulleys require maintenance to ensure the correct operation of the generator.
Además se requiere un dispositivo que pueda funcionar con profundidades menores, ya que un sistema peso-contrapeso requiere que exista cierta distancia entre el eje y el fondo marino. It also requires a device that can operate at lower depths, since a system Weight-counterweight requires that there be a certain distance between the axis and the seabed.
En consecuencia, resulta evidente que un dispositivo con menos partes móviles en el fondo marino y una menor cantidad de partes metálicas ofrece prestaciones en cuanto a menor mantenimiento, facilidad y evita la corrosión de sus partes. Además, podría disponerse en aguas con menor profundidad dado que es un dispositivo más compacto que los dispositivos de la técnica.  Consequently, it is clear that a device with fewer moving parts on the seabed and a smaller amount of metal parts offers benefits in terms of lower maintenance, ease and prevents corrosion of its parts. In addition, it could be arranged in waters with less depth since it is a more compact device than the devices of the technique.
Por consiguiente, la presente invención hace referencia a un dispositivo generador de energía que presenta menos partes móviles y metálicas en el fondo marino, requiriendo un menor mantenimiento.  Accordingly, the present invention refers to an energy generating device that has fewer moving and metallic parts on the seabed, requiring less maintenance.
Además, de manera sorprendente, la presente invención puede utilizarse sin necesidad de que exista una distancia entre el fondo marino y el eje, solo se requiere que exista espacio suficiente para permitir la rotación.  In addition, surprisingly, the present invention can be used without the need for a distance between the seabed and the axis, only sufficient space is required to allow rotation.
Por tanto, la presente invención hace referencia a un dispositivo generador de energía a partir de la energía producida por el oleaje que comprende:  Therefore, the present invention refers to an energy generating device from the energy produced by the waves comprising:
- un flotador;  - a float;
- un elemento de interconexión;  - an interconnection element;
- un convertidor de movimiento alternativo en rotacional; y  - an alternative to rotational movement converter; Y
- un eje acoplado a un convertidor de energía rotacional en energía eléctrica de modo que una rotación en el eje ocasiona una rotación convertidor de energía rotacional en energía eléctrica;  - an axis coupled to a rotational energy converter in electrical energy so that a rotation in the axis causes a rotation converter of rotational energy into electrical energy;
en el que el flotador está unido al elemento de interconexión que, a su vez, entra en contacto con el convertidor de movimiento alternativo en rotacional generando una rotación en el eje, dicho dispositivo comprende además un segundo flotador que se encuentra sometido a una fuerza de flotación menor a la del primer flotador interconectado al convertidor de movimiento alternativo en rotacional ejerciendo sobre el conversor una fuerza de menor magnitud y sentido contrario a la fuerza ejercida por el primer flotador. in which the float is connected to the interconnecting element which, in turn, comes into contact with the rotational reciprocating converter generating a rotation in the shaft, said device further comprises a second float that is subjected to a lower buoyant force than that of the first float interconnected to the rotational reciprocating converter, exerting a force of less magnitude and direction opposite to the converter the force exerted by the first float.
Preferentemente, el convertidor de movimiento alternativo en rotacional es una rueda dentada y dicha rueda dentada posee un mecanismo de trinquete, permitiendo que la rueda gire libremente en el sentido en que el flotador se mueve desde la cresta de la ola hacia el valle .  Preferably, the rotational reciprocating converter is a cogwheel and said cogwheel has a ratchet mechanism, allowing the wheel to rotate freely in the direction in which the float moves from the crest of the wave to the valley.
Aún más preferentemente, el convertidor de movimiento alternativo en rotacional es un sistema de poleas .  Even more preferably, the alternative rotational movement converter is a pulley system.
De manera especialmente preferente, el elemento de interconexión es una cadena.  Especially preferably, the interconnection element is a chain.
En una realización particular, el eje comprende al convertidor de movimiento alternativo en rotacional en la que, preferentemente, el convertidor es un rebaje dispuesto en el eje que realiza un acople mecánico entre el eje y el elemento de interconexión.  In a particular embodiment, the shaft comprises the rotational reciprocating converter in which, preferably, the converter is a recess arranged on the shaft that makes a mechanical coupling between the shaft and the interconnecting element.
En otra realización particular el convertidor de energía rotacional en energía eléctrica es un motor convencional dispuesto de modo que a la entrada se proporcione la rotación para tener una tensión de salida en los devanados.  In another particular embodiment, the rotational energy converter in electric energy is a conventional motor arranged so that the input is provided with rotation to have an output voltage in the windings.

La figura 11 muestra un detalle del convertidor de energía rotacional en eléctrica.  Figure 11 shows a detail of the rotational energy converter in electricity.
La figura 12 muestra un detalle del engranaje de interconexión entre flotadores.  Figure 12 shows a detail of the interconnection gear between floats.
Las figuras 1 a 3 muestran un generador de energía eléctrica. Particularmente, en esta realización el convertidor -7- de energía rotacional en eléctrica se encuentra sumergido con una base -6- fija en el fondo marino. El generador comprende un primer flotador -1-, un segundo flotador -2-, una cadena -8- de interconexión entre flotadores, un engranaje -3-, un soporte -5- y el convertidor -7- anteriormente mencionado. Figures 1 to 3 show an electric power generator. Particularly, in this embodiment the converter -7- of rotational energy in electricity is submerged with a base -6- fixed on the seabed. The generator comprises a first float -1-, a second float -2-, an interconnection chain -8- between floats, a gear -3-, a support -5- and the converter -7- mentioned above.
La disposición de dichas partes en el presente generador permite que al pasar una ola sobre el generador el flotador -1- es sometido a una fuerza hacia arriba moviendo hacia arriba la cadena -8- y generando en el engranaje -3- un movimiento en sentido horario. Pasada la cresta de la ola el flotador se mueve hacia abajo. En este momento, para mantener la tensión de la cadena, un segundo flotador -2- realiza una fuerza hacia arriba ocasionando, por acción de la cadena -8-, un movimiento en sentido antihorario en el engranaje -3-. De manera especialmente preferente, el engranaje -3- se mueve libremente sin mover el eje -4- en sentido antihorario para asi permitir que el segundo flotador -2- con una fuerza mínima pueda mantener la tensión en la cadena -8-.  The arrangement of said parts in the present generator allows that when a wave passes over the generator the float -1- is subjected to an upward force by moving up the chain -8- and generating in the gear -3- a movement in the direction schedule. After the crest of the wave the float moves down. At this time, to maintain the chain tension, a second float -2- performs an upward force causing, by chain action -8-, a counterclockwise movement in the gear -3-. Particularly preferably, the gear -3- moves freely without moving the axis -4- counterclockwise in order to allow the second float -2- with minimal force to maintain the tension in the chain -8-.
Por consiguiente el engranaje -3- se encuentra unido al eje -4- por medios que permitan transmitir el movimiento rotacional en un sentido de giro y girar libremente en el otro. Además, dependiendo de la longitud del eje -4- conviene disponer soportes con algún tipo de rodamiento que permitan la rotación del eje -4-. El movimiento rotacional generado sobre el eje -4- se transmite a un convertidor -7- de energía rotacional en eléctrica.  Therefore the gear -3- is attached to the axis -4- by means that allow the rotational movement to be transmitted in one direction of rotation and freely rotated in the other. In addition, depending on the length of the axis -4- it is convenient to have supports with some type of bearing that allow the rotation of the axis -4-. The rotational movement generated on the axis -4- is transmitted to a converter -7- of rotational energy into electrical.
La figura 4 muestra una realización ejemplar en la cual se disponen tres convertidores -7- de movimiento rotacional en energía eléctrica que se hacen girar con una disposición especial de la cadena -8- para mejorar las pérdidas y tener una generación de energía eléctrica más eficiente .  Figure 4 shows an exemplary embodiment in which three converters -7- of rotational movement in electrical energy are arranged which are rotated with a special arrangement of the chain -8- to improve losses and have a more efficient generation of electrical energy .
Las figuras 5 a 7 muestran un generador de energía según la presente invención en la cual el conversor -7- de movimiento rotacional en energía eléctrica se encuentra ubicado sobre una plataforma -6- flotante. En esta realización el conversor -7- se dispone flotante por medios de una base -61- con una fuerza de flotación suficiente para mantener el conversor -7- sobre el nivel del agua. Para esta realización la cadena -8- se dispone como se muestra en las figuras y disponen engranajes adicionales para garantizar su funcionamiento. Figures 5 to 7 show a power generator according to the present invention in which the -7- converter of rotational movement in electrical energy is located on a floating platform -6-. In this embodiment the converter -7- is floated by means of a base -61- with a sufficient buoyant force to maintain the converter -7- above the water level. For this embodiment, the chain -8- is arranged as shown in the figures and has additional gears to ensure its operation.
Las figuras 8 y 9 muestran una disposición de tres conversores -7- sobre una plataforma -6- dispuesta con columnas -62- fijas al fondo marino. Nótese que esta disposición de tres conversores podría realizarse de manera similar a la descrita en la figura -7- utilizando una base -61- flotante.  Figures 8 and 9 show an arrangement of three converters -7- on a platform -6- arranged with columns -62- fixed to the seabed. Note that this arrangement of three converters could be carried out in a manner similar to that described in Figure -7- using a floating base -61-.
La figura 10 muestra una disposición de tres conversores -7- sobre una plataforma -6- dispuesta con columnas -62- fijas al fondo marino. Nótese que en esta realización los conversores se encuentran sumergidos y que el número de conversores puede aumentar en todos los casos según los requerimientos de cada instalación.  Figure 10 shows an arrangement of three converters -7- on a platform -6- arranged with columns -62- fixed to the seabed. Note that in this embodiment the converters are submerged and that the number of converters can increase in all cases according to the requirements of each installation.
La figura 11 muestra un detalle de conversor -7- de movimiento rotacional en energía eléctrica, donde se puede observar la conexión del engranaje -3- al eje -4- y la conexión entre el eje -4- y el motor -73-. La conexión entre el eje -4- y el motor -73- pasa por un conjunto de engranajes -72- que se disponen, preferentemente al exterior de un compartimiento -71- para mantener seco el motor. La disposición exterior a dicho compartimiento -71- del conjunto de engranajes provee la ventaja de que los engranajes, en caso de ser un conversor -7- inmerso en el fondo marino se enfriarán gracias al agua mantenida en la cámara exterior. La figura 12 muestra un detalle de las conexiones del eje -4-. El eje -4- se encuentra unido al engranaje -3-, y preferentemente, poseen un medio para que solo se realice transferencia de movimiento entre engranaje -3- y eje -4- en un sentido de rotación mientras que en el otro sentido el engranaje -3- girará libremente sobre el eje -4-, es decir, posee un mecanismo de trinquete. Este engranaje -3- está en contacto mediante medios de la técnica anterior a un elemento de interconexión entre flotadores y engranaje que en este caso particular es una cadena -8-. Dada la longitud del eje conviene utilizar soportes -5- que comprendan un mecanismo de tipo rodamiento -51- y asi facilitar la rotación del eje, causando el menor rozamiento posible. Figure 11 shows a detail of converter -7- of rotational movement in electric energy, where the connection of the gear -3- to the axis -4- and the connection between the axis -4- and the motor -73- can be observed. The connection between the shaft -4- and the motor -73- goes through a set of gears -72- that are arranged, preferably outside a compartment -71- to keep the engine dry. The external arrangement to said compartment -71- of the gear set provides the advantage that the gears, in case of being a converter -7- immersed in the seabed will be cooled thanks to the water maintained in the outer chamber. Figure 12 shows a detail of the shaft connections -4-. The axis -4- is attached to the gear -3-, and preferably, they have a means for only movement transfer between gear -3- and axis -4- in one direction of rotation while in the other direction the gear -3- will rotate freely on the axis -4-, that is, it has a ratchet mechanism. This gear -3- is in contact by means of prior art means to an interconnection element between floats and gear which in this particular case is a chain -8-. Given the length of the shaft, it is convenient to use brackets -5- that comprise a bearing type mechanism -51- and thus facilitate the rotation of the shaft, causing the least possible friction.
