Abstract
Description
un generador instalado en su interior y transforma la energía mecánica en energía eléctrica. De esta forma, la energía del agua es aprovechada por la turbina hidráulica, activada por la masa de agua que pasa por su interior, y se utiliza para producir energía eléctrica conectando el eje de la turbina con un generador eléctrico (alternador), que transforma la a generator installed inside and converts mechanical energy into electrical energy. In this way, the energy of the water is used by the hydraulic turbine, activated by the mass of water that passes through it, and is used to produce electrical energy by connecting the turbine shaft with an electric generator (alternator), which transforms the
5 energía mecánica en energía eléctrica. 5 mechanical energy in electrical energy.
La potencia eléctrica que se puede obtener depende de la cantidad de agua canalizada a la turbina, de la presión y del rendimiento eléctrico del generador. El agua que sale de la turbina es devuelta al mar una vez ha atravesado la tobera sin sufrir ninguna alteración. The electrical power that can be obtained depends on the amount of water channeled to the turbine, the pressure and the electrical efficiency of the generator. The water that leaves the turbine is returned to the sea once it has crossed the nozzle without suffering any alteration.
10 Dicha energía eléctrica alimenta un motor eléctrico o un motor híbrido, usados para mover el barco o bien puede almacenarse en baterías para su uso posterior. 10 Said electric power feeds an electric motor or a hybrid motor, used to move the boat or it can be stored in batteries for later use.
El casco del buque es modificado para la instalación del conducto, que preferentemente se The hull of the ship is modified for the installation of the duct, which is preferably
15 escoge con forma de tobera, pero puede utilizarse cualquier otro tipo de conducto con una geometría favorable para canalizar el agua, y el resto de elementos necesarios para la generación de energía eléctrica, principalmente los generadores eléctricos, por lo que previamente es preciso realizar los cálculos necesarios de resistencia al avance, cavitación, dimensionamiento y en general, cálculos de comportamiento en la mar en diferentes 15 it chooses with a nozzle shape, but any other type of conduit with a favorable geometry can be used to channel the water, and the rest of the elements necessary for the generation of electrical energy, mainly the electric generators, so that it is previously necessary to perform necessary calculations of resistance to the advance, cavitation, sizing and in general, calculations of behavior in the sea in different
20 regímenes de velocidad del buque. 20 ship speed regimes.
Realmente, el diseño exterior de la carena del buque, gradientes de presión y las eficientes formas en la resistencia al avance, no se modifican en absoluto, sino que la presente invención, respetando totalmente la geometría del casco siempre que sea posible, propone Actually, the exterior design of the ship's hull, pressure gradients and the efficient ways in the resistance to the advance, are not modified at all, but the present invention, totally respecting the geometry of the hull whenever possible, proposes
25 una construcción del tipo de los buques con proa móvil. 25 a construction of the type of ships with moving bow.
Las modificaciones en el diseño del casco, de acuerdo a la presente invención, integran la física y mecánica de fluidos ya testada en las centrales hidráulicas. El diseño concreto y su adaptación a los diferentes tipos de buques, responde una multitud de variables que influyen The modifications in the design of the hull, according to the present invention, integrate the physics and mechanics of fluids already tested in the hydraulic power plants.

La geometría de la tobera puede adoptar distintas curvaturas, en función del efecto y las prestaciones buscadas, pero de acuerdo a otra realización de la invención, la tobera puede seguir un diseño completamente recto desde la entrada hasta el fondo del buque, con la longitud, inclinación y dimensiones más apropiadas para cada buque. The geometry of the nozzle can adopt different curvatures, depending on the effect and the performance sought, but according to another embodiment of the invention, the nozzle can follow a completely straight design from the entrance to the bottom of the ship, with the length, tilt and dimensions most appropriate for each vessel.
Por supuesto, en caso de mantener cerradas las compuertas a la entrada del conducto, ya sea en forma de tobera o cualquier otra forma elegida, la hidrodinámica del buque se mantiene intacta y, al no permitir la entrada de agua, no existe ningún efecto de frenado. Hay que tener en cuenta que tanto las entradas como las salidas disponen de un cierre estanco en navegación que permite determinar la apertura y cierre de dichas compuertas o escotillas de los conductos cuando las condiciones sean o no favorables para el máximo rendimiento de trabajo del sistema. Of course, in case the gates are closed at the entrance of the duct, either in the form of a nozzle or in any other way chosen, the hydrodynamics of the vessel remains intact and, since it does not allow the entry of water, there is no effect of braking. It must be taken into account that both the entrances and the exits have a sealed closure in navigation that allows to determine the opening and closing of said gates or hatches of the ducts when the conditions are favorable or not for the maximum working performance of the system.
El generador que se conecta a cada una de las turbinas hidráulicas se representa en la figura 7 ocupando un espacio adicional y conectado a cierta distancia de la turbina, pero de acuerdo a una realización alternativa de la presente invención, el generador consiste en un generador eléctrico integrado en la propia turbina, preferentemente a su alrededor, de forma que aprovecha mejor el espacio disponible. The generator that connects to each of the hydraulic turbines is represented in Figure 7 occupying an additional space and connected at a certain distance from the turbine, but according to an alternative embodiment of the present invention, the generator consists of an electric generator integrated into the turbine itself, preferably around it, so that it makes better use of the available space.
La figura 8 muestra en detalle una vista inferior de un buque con bulbo donde, de acuerdo a una de las realizaciones de la invención, se aprovecha precisamente dicho bulbo para disponer en su fondo una salida (12) para una tobera. Figure 8 shows in detail a bottom view of a ship with a bulb where, according to one of the embodiments of the invention, said bulb is used precisely to provide at its bottom an outlet (12) for a nozzle.
La entrada para la tobera o conducto elegido también puede ubicarse, de acuerdo a una de las realizaciones, en el frente del bulbo de proa o cualquier otra zona del casco en la obra viva, que permita la física necesaria para activar el sistema. Así, la tobera o conducto elegido, atraviesa el bulbo completamente y evacúa el agua bien por el fondo o bien por un costado tal y como se ha visto en las anteriores realizaciones. The entrance to the nozzle or conduit chosen can also be located, according to one of the embodiments, in the front of the bow bulb or any other area of the hull in the live work, which allows the necessary physics to activate the system. Thus, the nozzle or conduit chosen, crosses the bulb completely and evacuates the water either by the bottom or by a side as it has been seen in the previous embodiments.
Otra realización alternativa para el sistema de la presente invención se refiere a instalar la entrada de la tobera en la quilla del buque, en el ángulo estudiado de cada buque más favorable, siempre cumpliendo con las normas de construcción de las sociedades de clasificación Another alternative embodiment for the system of the present invention relates to installing the inlet of the nozzle in the keel of the vessel, at the angle studied of each most favorable vessel, always complying with the construction standards of the classification societies

10 de consumo y rendimiento demasiado altos. Esto no es relevante para las situaciones de frenado, pero sin embargo, sí es relevante para un eventual funcionamiento durante el orden de marcha con los motores encendidos, donde la relación entre la energía eléctrica generada por las turbinas frente a la pérdida de velocidad, tiempo y consumo extra por resistencia al avance es fundamental para determinar si es recomendable activar el sistema 10 consumption and performance too high. This is not relevant for braking situations, but nevertheless, it is relevant for eventual operation during the running order with the engines running, where the ratio between the electrical energy generated by the turbines versus the loss of speed, time and extra consumption due to advance resistance is essential to determine if it is advisable to activate the system
