DESCRIPCIONDESCRIPTION
Generador electrico accionado por cometas.Electric generator powered by kites.
Sector de la tecnicaTechnology Sector
La invention se encuadra dentro del sector de la generation electrica por energlas renovables, en este caso por la action de la energla eolica.The invention falls within the sector of the electric generation by renewable energies, in this case by the action of wind energy.
Antecedentes de la invencionBackground of the invention
El aprovechamiento del viento para la production de energla electrica se ha llevado a cabo a traves de varios tipos de aerogeneradores cuyo sistema se basa basicamente en la incidencia del viento sobre unas helices o palas haciendolas girar. Estas helices estan solidarias a un rotor que genera electricidad mientras va girando en un generador.The use of wind for the production of electric energy has been carried out through several types of wind turbines whose system is based basically on the incidence of wind on propellers or blades by rotating them. These propellers are in solidarity with a rotor that generates electricity while rotating in a generator.
Los sistemas eolicos conocidos hasta el momento equipados con cometas que aprovechan la energla contenida en el viento se basan en un sistema electronico acoplado en la cometa haciendola girar en clrculos y accionando mediante un cable un volante de inercia. Otros sistemas acoplan pequenas helices en la cometa de manera que cuando esta se encuentra en vuelo, las hacen girar generando electricidad que se transmite por el mismo hilo conductor que soporta la cometa.The wind systems known so far equipped with kites that take advantage of the energy contained in the wind are based on an electronic system coupled to the kite by rotating it in circles and by means of a cable driving a flywheel. Other systems couple small helices in the kite so that when it is in flight, they rotate them generating electricity that is transmitted by the same conducting wire that supports the kite.
Otra forma de crear energla conocida es a traves del ascenso, aprovechando la fuerza de arrastre del hilo para mover un generador. Esta etapa debe ser seguida por otra etapa de recuperation donde la cometa en modo “bandera”, para minimizar la resistencia del viento, es recogida completandose as! el ciclo. La conversion de energla se produce a traves de unos cabrestantes conectados a un generador. Los generadores producen energla mientras la cometa asciende arrastrada por el viento y a su vez actuan como motores para recoger el cable en la etapa de recuperacion.Another way to create known energy is through ascent, taking advantage of the drag force of the wire to move a generator. This stage must be followed by another recovery stage where the kite in "flag" mode, to minimize wind resistance, is collected by completing it! the cycle. The conversion of energy occurs through winches connected to a generator. The generators produce energy while the kite rises by the wind and in turn act as motors to collect the cable in the recovery stage.
Explication de la invencionExplanation of the invention
El modelo de generacion planteado se basa en la accion ejercida por el viento sobre varias cometas dispuestas de tal manera que se muevan en una determinada direction y de forma clclica, unidas mediante unos hilos o llneas a una cadena que circula por un carril.The proposed generation model is based on the action exerted by the wind on several kites arranged in such a way that they move in a certain direction and in a cyclical way, connected by means of wires or lines to a chain that circulates along a lane.
La forma en la que las cometas se mueven es la misma en la que un deportista de kitesurf se mueve por la costa de una playa de un lado hacia otro. La direccion del viento se encontrarla perpendicular a la direccion del movimiento de las cometas. Cuando el viento incide en la cometa genera traction y dependiendo del angulo o inclination que tenga la cometa en ese momento con respecto al viento y su velocidad de desplazamiento generara menor o mayor potencia.The way in which kites move is the same in which a kitesurfing athlete moves along the coast of a beach from one side to another. The wind direction will be found perpendicular to the direction of the kite movement. When the wind hits the kite, it generates traction and depending on the angle or inclination that the kite has at that time with respect to the wind and its travel speed will generate less or greater power.
El tipo de cometa a utilizar serla el tipo delta hinchable compuesta de cuatro llneas; dos llneas centrales o de traccion conectadas a la parte delantera de la cometa y otras dos llneas laterales o de direccion(una en cada extremo) conectadas a los extremos posteriores.The type of kite to be used would be the inflatable delta type composed of four lines; two central or traction lines connected to the front of the kite and two other lateral or steering lines (one at each end) connected to the rear ends.

Las llneas centrales tienen la funcion de desplazar la cometa hacia arriba o abajo disminuyendo o aumentando la potencia o traccion de la cometa, de manera que cuando la cometa se encuentra en su parte mas elevada la potencia es minima y cuando se encuentra en su parte mas baja la potencia que genera es la maxima. Las llneas laterales tienen la funcion de girar la cometa haciendola cambiar de direction hacia la izquierda o derecha, lo que se conoce como ventana de viento. Dentro de esta ventana de viento existen varias posiciones utilizando el rango horario desde las 9 hasta las 3 para determinar la position de la cometa, de manera que a las 9 se encontrarla en su parte mas baja en el lado izquierdo, a las 12 se posicionarla en su parte superior central y a las 3 en la parte inferior derecha. El rango de posiciones desde las 9 hasta las 12 desplazarla la cometa hasta el lado izquierdo y el rango desde las 12 hasta las 3 hacia el lado derecho.The central lines have the function of moving the kite up or down by decreasing or increasing the power or traction of the kite, so that when the kite is at its highest part the power is minimal and when it is at its most Low the power it generates is the maximum. The lateral lines have the function of turning the kite making it change direction to the left or right, which is known as the wind window. Within this wind window there are several positions using the time range from 9 to 3 to determine the position of the kite, so that at 9 it will be found in its lowest part on the left side, at 12 it will be positioned in its upper central part and at 3 in the lower right. The range of positions from 9 to 12 o'clock will be moved by the kite to the left side and the range from 12 to 3 to the right side.
La forma de accionamiento de las llneas para el cambio de direccion serla de la misma manera que en kitesurf, donde el surfista agarrado a la barra tira de uno de sus extremos haciendo tirar de las llneas de direccion y esta a su vez del extremo del extremo posterior de la cometa. Esto provoca que un extremo de la cometa ofrezca mayor resistencia al viento y se desplace en un sentido. En el sistema planteado, en vez de una barra, las llneas laterales o de direccion estarlan enrolladas a los extremos del eje de un pequeno motor electrico de tal manera que al girar tire de una de las llneas y suelte la otra permitiendo as! dirigir la cometa en el momento y direccion deseados. Las llneas centrales son las llneas de traccion que conectan la cometa con una cadena de traccion que se encuentra girando dentro de un rail en la misma direccion que giran las cometas.The way of driving the lines for the change of direction would be in the same way as in kitesurfing, where the surfer holding the bar pulls one of its ends by pulling the direction lines and is in turn the end of the end Rear of the kite. This causes one end of the kite to offer greater wind resistance and travel in one direction. In the proposed system, instead of a bar, the lateral or steering lines will be rolled up to the ends of the shaft of a small electric motor in such a way that when turning, pull one of the lines and release the other one, thus allowing! direct the kite at the desired time and direction. The central lines are the traction lines that connect the kite with a traction chain that is turning inside a rail in the same direction that the kites rotate.
El rail permite contener a la cadena dentro de el y su forma serla identica a una pista de atletismo, es decir, un ovalo que consta de dos llneas rectas paralelas entre si unidas mediante dos curvas a los extremos. En las partes ovaladas de los extremos es donde se efectuarla el cambio de direccion de la cometa donde un control electronico accionarla el motor electrico tirando y soltando las llneas laterales, lo que provoca que la cometa cambie de posicion y sea empujada por el aire en sentido opuesto. El conjunto del rail se encontrarla inclinado en un angulo perpendicular a las llneas de la cometa disminuyendo as! que los esfuerzos verticales y horizontales que ocasiona la cometa por su arrastre y el desgaste de la cadena circulando por el interior del rail.The rail allows the chain to be contained within it and its shape is identical to an athletic track, that is, an oval consisting of two straight lines parallel to each other joined by two curves to the ends. In the oval parts of the ends is where the change of direction of the kite will be carried out where an electronic control will be activated by the electric motor by pulling and releasing the lateral lines, which causes the kite to change position and be pushed by the air in direction opposite. The rail assembly will be found inclined at an angle perpendicular to the lines of the kite thus decreasing! that the vertical and horizontal stresses caused by the kite due to its drag and the wear of the chain circulating inside the rail.
La instalacion contarla con un mlnimo de cuatro cometas, dispuestas de tal manera que la distancia entre ellas sea la misma y esten enfrentadas entre si. De esta manera cuando una cometa se encuentre en un extremo del recorrido, la otra se encuentre en el extremo opuesto, mientras que las otras dos se encuentran enfrentadas en la mitad de la parte rectillnea del rail, creando un movimiento clclico continuo.The installation will have a minimum of four kites, arranged in such a way that the distance between them is the same and they are facing each other. In this way when a kite is at one end of the path, the other is at the opposite end, while the other two are facing each other in the middle of the straight part of the rail, creating a continuous cyclic movement.
La longitud y la anchura del rail es la minima que permita que las cometas al efectuar el cambio de direccion no se interfieran entre si. Su forma serla como la de un prisma pero hueco por su parte interior para que permita la circulacion de la cadena de traccion. En el centro de la cara superior, un hueco a lo largo de toda su longitud permite la union de dicha cadena con las llneas centrales de la cometa.The length and width of the rail is the minimum that allows kites to change direction not to interfere with each other. Its shape would be like that of a prism but hollow on the inside to allow the circulation of the traction chain. In the center of the upper face, a gap along its entire length allows the union of said chain with the central lines of the kite.
La cadena de traccion tendrla una forma especial de manera que tenga una especie de rodamientos y rodillos, cada uno de ellos de la misma anchura colocados en cada uno de sus cuatro lados de manera que la permitan circular libremente por el rail con el menor rozamiento posible.The traction chain will have a special shape so that it has a kind of bearings and rollers, each of them of the same width placed on each of its four sides so that they allow it to move freely along the rail with the least possible friction .

El sistema para mover el generador serla el sistema cadena-pinon donde la cadena movida por las cometas mueve a su vez una corona engranada a ella en uno de los extremos del rail. Esta corona se encuentra solidaria al eje del generador haciendolo girar y crear energla electrica.The system to move the generator would be the chain-pinon system where the chain moved by the kites in turn moves a crown geared to it at one end of the rail. This crown is integral to the generator shaft by rotating it and creating electric energy.
La colocacion de la instalacion se efectuarla en lugares donde exista un viento predominante en una direction concreta y donde las turbulencias del viento sean mlnimas.The installation will be installed in places where there is a predominant wind in a specific direction and where the turbulence of the wind is minimal.
El conjunto de la instalacion podrla colocarse sobre unos ralles de cremallera en forma circular para permitir girarla y colocar siempre las cometas en direccion perpendicular al viento en el caso de que este cambie de direccion.The whole of the installation could be placed on rack rails in a circular shape to allow it to rotate and always place the kites in a direction perpendicular to the wind in the event that it changes direction.
