Abstract

Mechanism for transformation of an alternative movement in a rotating movement. Specially designed to take advantage of the alternative movement of sea waves, captured through a reciprocating piston, consists of a pair of toothed crowns (3 and 5), with parallel axes and interconnected, which receive the movement of respective connecting rods (8 and 9), mounted with freedom of rotation on respective axes (6 and 7) and joined articulately to the reciprocating piston (12), counting these connecting rods with pawls (15 and 16), oriented in the opposite direction, so that one of said ratchets is operative when the piston moves in a certain direction, the other being inoperative, and vice versa, obtaining a continuous rotary movement in an output pinion (17) connected to one of the toothed crowns (5), with integral use of the power supplied by the waves, whether the piston moves in one direction or when it moves in the opposite direction.

Description

Mecanismo para transformación de un movimiento alternativo en un movimiento giratorio.Mechanism for transformation of a movement alternative in a rotating movement.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un mecanismo que ha sido especialmente concebido para transformar un movimiento alternativo en un movimiento rotativo o giratorio, como por ejemplo para generar energía eléctrica mediante el correspondiente generador y a expensas de una energía capaz de suministrar movimiento alternativo.The present invention relates to a mechanism which has been specially designed to transform a movement alternative in a rotating or rotating movement, such as to generate electricity through the corresponding generator and at the expense of an energy capable of supplying alternative movement

El mecanismo resulta de especial aplicación en aquellos casos en los que el movimiento alternativo es aprovechable en ambos sentidos, como por ejemplo el producido por el movimiento de vaivén de una plataforma marina.The mechanism is especially applicable in those cases in which the alternative movement is usable in both directions, such as the one produced by the movement swaying of a marine platform.

Antecedentes de la invenciónBackground of the invention

En el ámbito preferente de aplicación práctica de la invención, el de los generadores marinos a base de plataformas flotantes, se utilizan sistemas de transmisión de movimiento a base de pistones accionados por flotadores, de manera que, como tales pistones transmiten un movimiento alternativo, se hace preciso el concurso de sistemas de embrague que anulen el desplazamiento de tales pistones cuando éste sea contrario al sentido de giro previsto para el alternador propiamente dicho.In the preferred scope of practical application of the invention, that of marine generators based on floating platforms, transmission systems of movement based on float driven pistons, so that, as such pistons transmit an alternative movement, it requires the contest of clutch systems that annul the displacement of such pistons when it is contrary to direction of rotation provided for the alternator itself.

Esto supone una pérdida del 50% de la energía que recibe debido al movimiento del agua cada pistón o flotador.This means a loss of 50% of the energy that receives each piston due to the movement of water or float.

Descripción de la invenciónDescription of the invention

El mecanismo que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que es capaz de absorber la energía generada por el movimiento de las olas, tanto en un sentido como en otro, manteniéndose en todo momento el mismo sentido de giro para el generador eléctrico acoplado a dicho mecanismo.The mechanism proposed by the invention resolves in a fully satisfactory way the problem previously exposed, so that it is able to absorb the generated energy by the movement of the waves, both in one way and another, maintaining the same direction of rotation at all times for the electric generator coupled to said mechanism.

Para ello y de forma mas concreta dicho mecanismo está constituido, en su realización mas simple, por una pareja de coronas dentadas, idénticas entre sí, montadas sobre ejes paralelos y debidamente engranadas de manera que giran en sentidos contrarios, estando montada sobre cada uno de estos ejes y con libertad de giro una biela radial y estando a su vez dichas bielas unidas articuladamente a un pistón accionado por la fuente de movimiento alternativo de que se trate, como por ejemplo por la plataforma flotante marina. Cada una de estas bielas incorpora un trinquete montado basculantemente sobre las mismas y actuante sobre los dientes de la correspondiente corona dentada, con la particularidad de que dichos trinquetes están orientados en sentido contrario, de manera que cuando el pistón se desplaza en un determinado sentido una de las bielas arrastra en sentido angular a una de las coronas dentadas, permitiendo que el otro trinquete asociado a la segunda rueda dentada gire libremente, arrastrada por la primera y vice-
versa.For this and more specifically, said mechanism is constituted, in its simplest embodiment, by a pair of toothed crowns, identical to each other, mounted on parallel shafts and properly geared so that they rotate in opposite directions, being mounted on each of these axes and with freedom of rotation a radial connecting rod and said connecting rods being articulated jointly to a piston driven by the source of alternative movement in question, such as for example the floating marine platform. Each of these connecting rods incorporates a ratchet mounted pivotally thereon and acting on the teeth of the corresponding toothed crown, with the particularity that said ratchets are oriented in the opposite direction, so that when the piston moves in a certain direction a of the cranks, it draws angularly to one of the toothed crowns, allowing the other ratchet associated with the second cogwheel to rotate freely, dragged by the first and vice-
versa.

A una de estas dos ruedas dentadas está acoplado un piñón que, bien directamente o bien mediante una transmisión adecuada, transmitirá el movimiento de las coronas dentadas al eje del generador eléctrico.To one of these two sprockets is coupled a pinion that, either directly or through a transmission adequate, will transmit the movement of the crowned teeth to the axis of the electric generator.

Para resolver los desplazamientos en altura que se producen en los extremos articulados de las bielas con respecto al pistón, éste último está montado basculantemente sobre el correspondiente soporte.To solve the displacements in height that occur at the articulated ends of the cranks with respect to the piston, the latter is pivotally mounted on the corresponding support.

De esta manera toda la potencia suministrada por la plataforma flotante, tanto la generada en el desplazamiento de ida como de retroceso del pistón, es aprovechada por una u otra de las coronas dentadas, que finalmente suministran movimiento permanente, en un mismo sentido de giro, al eje de salida.In this way all the power supplied by the floating platform, both generated in the displacement of as if the piston recoils, it is used by one or the other of toothed crowns, which finally provide movement permanent, in the same direction of rotation, to the output shaft.

Para mejorar las condiciones de la transmisión motriz, las coronas dentadas serán de grandes dimensiones y considerable peso, o bien estarán asistidas por masas de inercia que tienden a absorber las oscilaciones en la intensidad del oleaje.To improve transmission conditions motor, toothed crowns will be large and considerable weight, or else they will be assisted by masses of inertia which tend to absorb oscillations in the intensity of the surf.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de la figura reseñada puede observarse como el mecanismo que la invención propone parte de una bancada (1) soporte de sus componentes sobre la que se establecen tres soportes, el primer soporte (2) para una primera corona dentada (3), y un segundo soporte (4), similar al anterior, para una segunda corona dentada (5) idéntica a la corona dentada (3), de manera que montadas sobre respectivos ejes paralelos (6 y 7), las coronas (3 y 5) engranan entre sí en su punto de tangencia.In view of the review figure you can be observed as the mechanism that the invention proposes part of a bench (1) support of its components on which they are established three supports, the first support (2) for a first crown serrated (3), and a second support (4), similar to the previous one, to a second toothed crown (5) identical to the toothed crown (3), of so that mounted on respective parallel axes (6 and 7), the crowns (3 and 5) engage each other at their point of tangency.

Sobre estos ejes (6 y 7) se montan a su vez con libertad de giro respectivas bielas (8 y 9), una de las cuales se une articuladamente por su extremo libre (11) al vástago (18) de un pistón (12), estando los extremos libres (10) y (11) de dichas bielas (8) y (9) relacionados articuladamente entre sí a través de una biela intermedia (19), de manera que el pistón (12) es capaz de suministrar a dichas bielas el movimiento alternativo generado por el oleaje, a través de cualquier medio convencional apropiado que no afecta en absoluto a la esencia de la invención.On these axes (6 and 7) they are mounted in turn with freedom of rotation respective connecting rods (8 and 9), one of which jointly joins at its free end (11) to the stem (18) of a piston (12), the free ends (10) and (11) of said connecting rods (8) and (9) jointly related to each other through an intermediate connecting rod (19), so that the piston (12) is capable of supply these cranks with the alternative movement generated by the waves, through any appropriate conventional means that do not  it affects the essence of the invention at all.

El pistón (12) está montado a través de un punto de basculación (13) sobre el correspondiente soporte (14), para permitir las necesarias oscilaciones de dicho pistón debidas al cambio de posición de la biela (9).The piston (12) is mounted through a point of tilt (13) on the corresponding support (14), for allow the necessary oscillations of said piston due to crank position change (9).

Las bielas (8 y 9) cuentan con respectivos trinquetes (15 y 16) actuantes sobre los dientes de las coronas (3), con la particularidad de que dichos trinquetes (15 y 16) adoptan posiciones contrarias, tal como se observa claramente en la figura, donde se aprecia que cuando el pistón (12) se desplaza hacia la izquierda, el trinquete (15) arrastra a la corona dentada (3) haciéndola girar en el sentido de la flecha representada también en la figura, mientras que el trinquete (16) salta sobre los dientes de la corona (5) resultando inoperante, de manera que dicha corona (5) gira a su vez en el sentido de la flecha que la asiste en la figura, arrastrada por la otra rueda dentada (3), transmitiendo finalmente el movimiento a un piñón o rueda dentada (17) engranada a la corona dentada (5), pero que igualmente podría estar engranado a la otra corona dentada (3).The connecting rods (8 and 9) have respective ratchets (15 and 16) acting on the crowns teeth (3), with the particularity that said ratchets (15 and 16) they adopt opposite positions, as clearly observed in the figure, where it can be seen that when the piston (12) moves to the left, the ratchet (15) drags the crown gear (3) by rotating it in the direction of the arrow also represented in the figure, while the ratchet (16) jumps over the crown teeth (5) being inoperative, so that said crown (5) turns in the direction of the arrow that assists it in the figure, dragged by the other cogwheel (3), finally transmitting the movement to a pinion or cogwheel (17) geared to the crown gear (5), but which could also be geared to the other toothed crown (3).

Cuando se produce el desplazamiento en sentido contrario del pistón (12), es decir hacia la derecha, es el trinquete (16) el que pasa a ser operante, moviendo la corona dentada (5) en el mismo sentido que en el caso anterior, pasando el trinquete (15) a resultar inoperante, de manera que la corona (3) es fácilmente arrastrada por la corona (5), que a su vez mantiene el mismo sentido de giro para el piñón de salida (17), al que como anteriormente se ha dicho estará asociado el generador eléctrico, o cualquier otro mecanismo que requiera de un movimiento giratorio.When the offset occurs opposite of the piston (12), that is to the right, is the ratchet (16) which becomes operant, moving the crown toothed (5) in the same direction as in the previous case, passing the ratchet (15) to be inoperative, so that the crown (3) It is easily dragged by the crown (5), which in turn keeps the same direction of rotation for the output pinion (17), which as previously said the electric generator will be associated, or any other mechanism that requires a movement rotary.
