Dispositivo aerogenerador vertical. Vertical wind turbine device
Objeto de la invenciónObject of the invention
La invención propone un dispositivo aerogenerador vertical, diseñado para conseguir el aprovechamiento máximo de la energía eólica transformada en energía cinética, pudiendo trabajar tanto con vientos fuertes como escasos, sin necesidad de motor de arranque. Antecedentes de la invención The invention proposes a vertical wind turbine device, designed to achieve maximum utilization of wind energy transformed into kinetic energy, being able to work with both strong and scarce winds, without the need for a starter motor. Background of the invention
Son conocidos en el estado de la técnica gran cantidad de aerogeneradores. Un aerogenerador es un generador eléctrico movido por una turbina eólica accionada por el viento. La energía eólica es en realidad energía cinética del aire en movimiento que proporciona energía mecánica a una hélice que a través de un sistema de transmisión mecánico, hace girar el rotor de un generador que convierte la energía mecánica rotacional en energía eléctrica. A large number of wind turbines are known in the state of the art. A wind turbine is an electric generator driven by a wind turbine driven by the wind. Wind power is actually kinetic energy of the moving air that provides mechanical energy to a propeller that, through a mechanical transmission system, rotates the rotor of a generator that converts rotational mechanical energy into electrical energy.
Existen diferentes tipos de aerogeneradores, dependiendo de su potencia, disposición de su eje de rotación, tipode generador,yotros. There are different types of wind turbines, depending on their power, arrangement of their axis of rotation, type of generator, and others.
Los aerogeneradores de eje vertical son aquellos en los que el giro del rotor es paralelo al suelo. Ejemplos de este tipo de aerogeneradores se describe por ejemploenlas patenteWO2008/135119,oenlapatente DE 19521740. Vertical axis wind turbines are those in which the rotation of the rotor is parallel to the ground. Examples of this type of wind turbines are described for example in patent WO2008 / 135119, or in patent DE 19521740.
En los actuales diseños de los generadores, las turbinas no son capaces de arrancar sin la ayuda del motor, con vientos escasos, sin obtener el rendimiento deseado. Otros aerogeneradores que sí podrían aprovechar vientos escasos, disponen de un diseño poco robusto que podría provocar un derribo en fuertes vientos. In the current designs of the generators, the turbines are not able to start without the help of the engine, with low winds, without obtaining the desired performance. Other wind turbines that could take advantage of scarce winds, have a little robust design that could cause a breakdown in strong winds.
La gran cantidad de piezas y tornillos de unión para los diferentes elementos de los aerogeneradores hace que su montaje, instalaciónymantenimiento sea costoso, así como se necesita invertir gran cantidad de tiempo en estas operaciones. Descripción de la invenciónThe large number of parts and connecting screws for the different elements of the wind turbines makes their assembly, installation and maintenance costly, as well as a great deal of time in these operations. Description of the invention
Lainvenciónpropuesta consiste en un dispositivo aerogeneradorverticalque, conociendola gran cantidad de dispositivos existentes en este campo, destaca por su funcionamiento silencioso, sin hacer ruido. Su diseño de turbina le permite arrancar sólo sin la ayuda del motor, con vientosde sólo4m/s. The proposed invention consists of a vertical wind turbine device that, knowing the large number of existing devices in this field, stands out for its silent operation, without making noise. Its turbine design allows it to start only without the help of the engine, with winds of only 4m / s.
Lasformas convexasycóncavas alternadasde sus álabes en la disposición le permiten obtener un rendimiento altísimo aprovechando al máximo la energía cinética sin obstrucción al giro ergonómico. Además, su robustez mecánica le permite trabajar con vientos fuertes sin el temido derribo de sus elementos. The alternating convex and concave shapes of its vanes in the arrangement allow you to obtain a very high performance, taking full advantage of the kinetic energy without obstruction to the ergonomic rotation. In addition, its mechanical robustness allows it to work with strong winds without the dreaded demolition of its elements.
Su diseñodeturbina constadeun sistemade perfil que combina la obstrucción del viento con el desplazamiento del volumen másico sin la pérdida de carga por el fenómeno cilíndrico. Asimismo, su forma aerodinámica de la turbina que le confiere un buen arranque con vientos flojos,4m/s, no entra en pérdida aerodinámica con vientos de 18 m/sysuperiores, debido a la condición de sus álabes de parte convexaycóncava. Este perfil se ocupade noentrar enla sobrepresión. Its turbine design consists of a profile system that combines the obstruction of the wind with the displacement of the mass volume without the loss of load due to the cylindrical phenomenon. Likewise, its aerodynamic shape of the turbine that confers a good start to it with fl ow winds, 4m / s, does not enter aerodynamic loss with winds of 18 m / s and higher, due to the condition of its convex and concave blades. This profile deals with not entering the overpressure.
Las presiones axiales están controladas, la combinación de cojinetes de contacto angular con cojinetes cilíndricos, son suficientes para mantener la posición orbital en su eje sin el menor desplazamiento. Su conjunto estructural mantiene la rigidez y la geometría tando vibraciones. Axial pressures are controlled, the combination of angular contact bearings with cylindrical bearings, are sufficient to maintain the orbital position on its axis without the slightest displacement. Its structural assembly maintains rigidity and geometry when vibrating.
La turbina,fabricada con materialesde última generación, combina aleaciones de acero, aluminio y composites, paragarantizar tantoel compromiso mecánico de no mantenimiento en más de 20000 horas de uso, como la corrosión en más de 20 años. The turbine, manufactured with state-of-the-art materials, combines alloys of steel, aluminum and composites, to guarantee both the non-maintenance mechanical commitment in more than 20,000 hours of use, and corrosion in more than 20 years.
La facilidad de montaje es otra parte importante debido a su diseño de enlace de piezas tipo mecano de direcciones opuestas, no necesita de tornillos para sujetarse entre sí. Sus componentes se sujetan con encajes que simplifican el sistema con la mínima cantidadde tornillosyque estossolosonpara posicionar. The ease of assembly is another important part due to its design of linking parts type of opposite directions, it does not need screws to hold each other. Its components are fastened with fittings that simplify the system with the minimum amount of screws and that these are only for positioning.
El mecano de la estructura, que comprende tres partes iguales, le confieren una gran robustez, un costomuy razonable,yalavezpoca resistenciaal viento. Esta estructura se aplica sólo a modelos de potencia superior a lo 10 KW, consiguiendo que sea más estética en los modelos destinados a las zonas urbanas que son las de menos potencia. The mecano of the structure, which comprises three equal parts, confers a great robustness, a very reasonable cost, and at the same time wind resistance. This structure applies only to models of power greater than 10 KW, making it more aesthetic in models destined for urban areas that are those with less power.
La transmisión se realiza a través de una corona dentada en línearectay un piñónde igual forma.El motor es un motor asíncrono de cuatro cuadrantes, sin escobillas. The transmission is carried out through a crown in a straight line and a pinion in the same way. The motor is an asynchronous four-quadrant motor, without brushes.
El software permite controlar el motor con relación a la velocidad del viento. El inversor también combina la función de entregar a la red, a la planta auxiliar, a un acumulador, de forma automática. Además con la lectura de suministro automatizada regulando en cada caso la frecuencia, tensión, voltaje, etc. The software allows to control the motor in relation to the wind speed. The inverter also combines the function of delivering to the network, to the auxiliary plant, to an accumulator, automatically. In addition to the automated supply reading regulating in each case the frequency, voltage, voltage, etc.
El peso es otrofactora tener en cuenta enel montaje del aerogenerador,pues sus piezas son un mecano que se transporta con un sistema convencional de pequeño tonelaje.Tampoco senecesitan grandes grúas para la elevación. The weight is otrofactora to take into account in the assembly of the wind turbine, since its parts are a mechano that is transported with a conventional system of small tonnage.Not large cranes are also needed for lifting.
La turbina puede llevar tres o más álabes, que según las condiciones del viento, se pueden instalar indistintamente. La realización preferente será con 5 álabes.
