Abstract
The invention relates to a system for producing electric power using gravity, said system including a rotary shaft (1) connected to a plurality of radial hydraulic cylinders (4) that are angularly equidistant from one another, such that the free end of each rod (5) bears a weight (6), said hydraulic cylinders (4) receiving pressure via radial hydraulic sleeves (3) which connect to a chamber (2) that is externally concentric to the rotary shaft (1). As the shaft (1) rotates, during the downward journey corresponding to one half-cycle, the weights (6) project outwards, while during the journey of the other half-cycle, the weights are retracted, with a larger lever arm being formed in the former case, thereby producing the continuous rotation of the shaft (1) using the force of gravity. During the radial weight (6)-extension and -retraction movements, both the weights and the rods (5) are guided through sleeves or jackets (7) which maintain the radial arrangement of said weights (6) and rods (5). The system further includes means for controlling the hydraulic circuit, comprising cams which detect the position of each weight (6) using a computer system.

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un sistema generador de energía eléctrica, utilizando como fuente energética la fuerza gravitatoria, sin necesidad de ningún tipo de energía adicional, y permitiendo su implantación en cualquier lugar, independientemente de las condiciones climatológicas y sin tener tampoco en cuenta las características geográficas del terreno o lugar en el que se estime oportuno o idónea su implantación, pudiendo ser ésta en las proximidades de centros de consumo de energía eléctrica. The present invention relates to an electric power generating system, using gravitational force as an energy source, without the need for any additional energy, and allowing its implementation anywhere, regardless of weather conditions and without taking into account the geographical characteristics of the land or place where its implementation is deemed appropriate or suitable, and this may be in the vicinity of electric power consumption centers.
Por lo tanto, el objeto de la invención es conseguir energía transformable en energía eléctrica, a partir de la fuerza gravitatoria, por lo que el ámbito de la invención se sitúa en el campo dedicado a la fabricación de máquinas y aparatos generadores de energía eléctrica. Therefore, the object of the invention is to achieve energy convertible into electrical energy, from the gravitational force, whereby the scope of the invention is in the field dedicated to the manufacture of machines and apparatus generating electric energy.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Se conocen sistemas generadores de energía eléctrica basados en un eje giratorio montado sobre dos soportes en correspondencia con los extremos, eje que incluye centrada y radialmente hacia el exterior una pluralidad de brazos que están equidistantes angularmente, de manera que
cada brazo está determinado por dos tramos articulados entre si con posibilidad de plegarse un tramo respecto del otro, concretamente el tramo libre, y siendo portador cada brazo en su extremo libre, es decir en el tramo plegable, de una pesa. Electric power generating systems are known based on a rotating shaft mounted on two supports in correspondence with the ends, an axis that includes a plurality of arms that are angularly equidistant, radially outwardly, so that each arm is determined by two sections articulated with each other with the possibility of folding one section with respect to the other, specifically the free section, and each arm being carrier at its free end, that is to say in the folding section, of a weight.
De esta forma, cuando gira el eje, en el recorrido descendente de cada pesa, los brazos se extienden, mientras que en el semi-ciclo ascendente los brazos se abaten, con lo que el brazo de palanca será mucho mayor cuando desciende que cuando asciende, y de ahí que se consiga el giro del eje tan solo a expensas de la fuerza de la gravedad. In this way, when the axis rotates, in the downward path of each weight, the arms extend, while in the ascending semi-cycle the arms are lowered, so that the lever arm will be much larger when it descends than when it ascends , and hence the rotation of the shaft is achieved only at the expense of the force of gravity.
Ese giro del eje, a través de una transmisión apropiada, puede utilizarse para accionar un alternador o para cualquier tipo de utilización. No obstante, el inconveniente que presenta este sistema es que mecánicamente resulta complejo puesto que los brazos han de estar formados por dos partes articuladas entre si, es decir por dos tramos, siendo accionable cada tramo en su plegado por un cilindro hidráulico, lo que supone un encarecimiento en el coste de fabricación, así como una posible oscilación o balanceo de las pesas con sus brazos en los movimientos giratorios de ascenso/descenso, lo que daría lugar a una pérdida de rendimiento y a un mal funcionamiento del sistema. This rotation of the shaft, through an appropriate transmission, can be used to drive an alternator or for any type of use. However, the drawback presented by this system is that it is mechanically complex since the arms must be formed by two parts articulated with each other, that is to say by two sections, each section being operable when folded by a hydraulic cylinder, which means an increase in the cost of manufacturing, as well as a possible oscillation or balancing of the weights with their arms in the rotating movements of ascent / descent, which would lead to a loss of performance and a malfunction of the system.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El sistema que se preconiza, basado en el punto anterior, presenta la particularidad de que las pesas, en lugar de ir montadas sobre brazos articulados, van montadas sobre cilindros hidráulicos, concretamente
sobre el extremo del vástago correspondiente a cada cilindro, eliminándose con ello los brazos y por lo tanto las articulaciones entre los mismos, no existiendo mas que cilindros hidráulicos que reciben la correspondiente presión hidráulica desde una cámara concéntrica externamente al propio eje, repartiéndose desde tal cámara la presión hidráulica a los distintos cilindros hidráulicos establecidos radialmente, de acuerdo con la apertura de las correspondientes válvulas. The system that is recommended, based on the previous point, has the peculiarity that the weights, instead of being mounted on articulated arms, are mounted on hydraulic cylinders, specifically on the end of the rod corresponding to each cylinder, thereby eliminating the arms and therefore the joints between them, there being no more than hydraulic cylinders that receive the corresponding hydraulic pressure from a concentric chamber externally to the axis itself, being distributed from such chamber the hydraulic pressure to the different radial cylinders established radially, according to the opening of the corresponding valves.
Otra característica de novedad es que las pesas van guiadas en camisas a modo de manguitos axiales y extremos con una longitud apropiada para que se corresponda con la suma de longitud de la pesa mas el vástago del correspondiente cilindro hidráulico, en la posición de extensibilidad del cilindro hidráulico, de manera tal que en los desplazamientos de extensibilidad y de retraimiento de los cilindros hidráulicos y por lo tanto las pesas, se consigue un guiado, asegurando el mantenimiento de la disposición radial para las propias pesas y para los vástagos a los que van fijadas. Another characteristic of novelty is that the weights are guided in shirts as axial and end sleeves with an appropriate length to correspond to the sum of the length of the weight plus the stem of the corresponding hydraulic cylinder, in the extensibility position of the cylinder hydraulic, so that in the movements of extensibility and retraction of the hydraulic cylinders and therefore the weights, a guidance is achieved, ensuring the maintenance of the radial arrangement for the weights themselves and for the stems to which they are fixed .
También se ha previsto que la circuitería hidráulica se complemente con un sistema de control en tiempo real para establecer la situación de cada pesa en cada momento y conseguir con ello una total sincronización en los movimientos de todos los componentes que participan en el sistema, de manera que ese control de la circuitería hidráulica correspondiente puede realizarse de forma mecánica a base de levas que detectan la posición de cada pesa mediante un sistema informático y en donde las levas, al pasar por la zona mas baja y mas alta del sistema, accionarían de forma mecánica al conjunto. It is also planned that the hydraulic circuitry be complemented with a real-time control system to establish the situation of each weight at each moment and thereby achieve a total synchronization in the movements of all the components that participate in the system, so that this control of the corresponding hydraulic circuitry can be performed mechanically based on cams that detect the position of each weight by means of a computer system and where the cams, when passing through the lowest and highest area of the system, would actuate mechanics to the whole.
Por consiguiente, el sistema de la invención realiza su movimiento de giro en base a la fuerza gravitoria, con la asistencia de los
cilindros hidráulicos, que son en definitiva los que mueven cada una de las pesas. Therefore, the system of the invention performs its turning movement based on gravitational force, with the assistance of Hydraulic cylinders, which are ultimately the ones that move each of the weights.
DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un único dibujo en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente: To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a single drawing is attached as an integral part of said description where Illustrative and non-limiting, the following has been represented:
La figura que se muestra en esa hoja única de planos corresponde a una vista en sección transversal del sistema productor de energía eléctrica realizado de acuerdo con el objeto de la invención. The figure shown in that single sheet of planes corresponds to a cross-sectional view of the electric energy producing system made in accordance with the object of the invention.
REALIZACIÓN PREFERENTE DE LA INVENCIÓN Como se puede ver en la figura referida, el sistema de la invención se constituye a partir de un eje (1) que es giratorio y estará apoyado por sus extremos en correspondientes soportes apropiados, cuyo eje es giratorio conjuntamente con una cámara (2) concéntrica pero externa al eje (1), de cuya cámara (2) se proyectan radialmente y de forma equidistante angularmente, una pluralidad de manguitos hidráulicos (3) a través de los cuales, desde la propia cámara (2), se alimentan otros tantos cilindros radiales (4) con su correspondiente vástago (5), de manera que en el extremo libre de cada uno de esos vástagos (5) de los cilindros radiales (4) va fijada una pesa (6) que es desplazable en el interior de una camisa o
manguito (7), que le sirve de guía y de mantenimiento en la disposición radial de cada pesa (6), cuando éstas se desplazan radialmente hacia el interior o hacia el exterior por efecto del retraimiento o extensibilidad de los vástagos (5) correspondientes a los cilindros hidráulicos (4). PREFERRED EMBODIMENT OF THE INVENTION As can be seen in the aforementioned figure, the system of the invention is constituted from an axis (1) that is rotatable and will be supported by its ends in corresponding appropriate supports, whose axis is rotatable together with a chamber (2) concentric but external to the axis (1), from whose chamber (2) a plurality of hydraulic sleeves (3) are projected radially and angularly equidistant through which, from the chamber (2) itself, as many radial cylinders (4) are fed with their corresponding rod (5), so that a weight (6) is movable at the free end of each of these rods (5) of the radial cylinders (4). inside a shirt or sleeve (7), which serves as a guide and maintenance in the radial arrangement of each weight (6), when they move radially inwards or outwards due to the withdrawal or extensibility of the stems (5) corresponding to the hydraulic cylinders (4).
De esta forma, cuando el eje (1) gira, se producirá lógicamente el giro de los cilindros hidráulicos (4) y con ello de las pesas (6), de forma tal que en el sentido de giro descendente, es decir en el ciclo donde el recorrido es descendente, cada pesa (6) se proyecta radialmente hacia el exterior, como se representa en la figura única, (en el semi-ciclo correspondiente a la parte de la derecha del dibujo), mientras que en el otro semi-ciclo u otra mitad del recorrido, que corresponde al semi-ciclo ascendente de las pesas (6), éstas se retraen (como se muestra en la mitad de la izquierda del dibujo), todo ello de manera tal que en el recorrido del semi-ciclo de descenso, el brazo de palanca que establecen los vástagos (5) con la pesa (6) es mayor que el correspondiente brazo de palanca cuando se produce el movimiento de ascenso, lo que hace que el eje (1) pueda seguir girando únicamente a expensas de la fuerza de la gravedad. Las pesas se desplazarán accionadas preferentemente por un sistema hidráulico, tal y como se ha comentado, si bien dicho sistema podría ser sustituido por un sistema neumático, o una transmisión asociada a un motor eléctrico o por cualquier otro mecanismo que pueda ser debidamente controlado, sin que ello afecte a la esencia de la invención. In this way, when the shaft (1) rotates, the rotation of the hydraulic cylinders (4) and with that of the weights (6) will logically occur, so that in the direction of downward rotation, that is in the cycle where the path is descending, each weight (6) is projected radially outwards, as shown in the single figure, (in the semi-cycle corresponding to the right part of the drawing), while in the other half- cycle or other half of the path, which corresponds to the ascending semi-cycle of the weights (6), these are retracted (as shown in the middle of the left of the drawing), all in such a way that in the path of the semi- lowering cycle, the lever arm established by the rods (5) with the weight (6) is larger than the corresponding lever arm when the ascent movement occurs, which makes the axis (1) can continue to rotate only at the expense of the force of gravity. The weights will be preferably driven by a hydraulic system, as mentioned, although this system could be replaced by a pneumatic system, or a transmission associated with an electric motor or by any other mechanism that can be properly controlled, without that this affects the essence of the invention.
Para conseguir una máxima impulsión del sistema, y para evitar que se detenga o sea frenado, debe existir una total y correcta sincronización, basándose en un sistema informático que controle en tiempo real la situación de cada pesa (6), de manera que procesando la información se podrá decidir los tiempos y velocidades para los correspondientes
cilindros hidráulicos (4) y por lo tanto para sus vástagos (5), de manera que para simplificar el sistema se puede disponer un conjunto de levas que al pasar por la zona mas baja y mas alta del sistema accionen de forma mecánica al mismo.
To achieve maximum system drive, and to avoid stopping or stopping, there must be a total and correct synchronization, based on a computer system that controls in real time the situation of each weight (6), so that processing the information may decide the times and speeds for the corresponding hydraulic cylinders (4) and therefore for their stems (5), so that to simplify the system a set of cams can be arranged that, by passing through the lowest and highest zone of the system, mechanically actuate it.
