Object of the invention

La presente invención se refiere a un seguidor solar para una instalación fotovoltaica, del tipo de las que conjuga varios paneles solares, cada uno de los cuales presenta un medio de variación de la inclinación estacional del panel y un eje de giro este-oeste para su orientación horaria provisto de medios de acoplamiento con una transmisión mecánica que permite el accionamiento conjunto de todos los paneles alineados.The present invention relates to a follower solar for a photovoltaic installation, of the type of which It combines several solar panels, each of which presents a means of variation of the seasonal inclination of the panel and an axis East-west turn for your time orientation provided with coupling means with a mechanical transmission which allows the joint operation of all panels aligned.

Background of the invention

Los equipos actuales de producción de energía solar, que montan placas fotovoltaicas en un panel, la máxima captación energética se produce cuando se sitúan perpendicularmente a los rayos solares. Para ello, los paneles se mueven en dos ejes, uno de rotación vertical y otro que varía su posición angular, de forma que se consigue una óptima orientación independientemente de la estación del año en la que nos encontremos, puesto que el sol modifica su altura en función de la hora del día y también estacionalmente.Current energy production equipment solar, which mount photovoltaic panels on a panel, the maximum energy collection occurs when they are perpendicularly to the sun's rays. To do this, the panels move in two axes, one of vertical rotation and another that varies its angular position, of so that optimal orientation is achieved regardless of the season of the year in which we find ourselves, since the sun modify its height depending on the time of day and also seasonally

En el documento ES-1050814 se describe un seguidor solar que presenta una plataforma o carril circular y un mecanismo para variar el ángulo de cada una de las placas situadas en un panel. Por su parte el documento ES-1044310 describe un seguidor de dos ejes, el eje de rotación gira el poste soporte del panel entorno a un carril circular y la variación angular mediante una bisagra a través de la cual se fija el panel al poste.In document ES-1050814 describes a solar tracker that presents a platform or lane circular and a mechanism to vary the angle of each of the plates located in a panel. For its part the document ES-1044310 describes a two-axis follower, the axis rotating the panel support post around a rail circular and angular variation by a hinge through which fixes the panel to the post.

El documento ES-2157857 describe un sistema autónomo e interactivo que comprende una base fija al suelo, un cuerpo giratorio respecto de la base con una cara basculante, que realiza dos movimientos de seguimiento del sol, uno azimutal entre 0 y 280º entre la salida y la puesta, y uno cenital entre 90 y 45º entre el horizonte y la posición mas alta del sol mediante un seguidor azimutal/cenital situando dicho campo perpendicular al sol para conseguir la máxima captación de fotones.Document ES-2157857 describes an autonomous and interactive system comprising a fixed base to floor, a rotating body with respect to the base with a face tilting, which performs two sun tracking movements, one azimuthal between 0 and 280º between the start and the start, and a zenith between 90 and 45º between the horizon and the highest position of the sun by means of an azimuthal / zenithal follower placing said field perpendicular to the sun to achieve maximum uptake of photons

El documento ES-1059590 describe un dispositivo de orientación de un conjunto de paneles solares, cada uno de los cuales comprende un poste soporte sobre el que se fija un panel de placas fotovoltaicas, que presenta dos ejes de giro que controlan de forma independiente el ángulo que el panel forma lateralmente y la inclinación del mismo, estando todos los postes de los paneles unidos por una transmisión mecánica con un mecanismo de accionamiento, que comandado por un único microcontrolador electrónico situado en uno de los paneles, determina la posición que debe tener éste en todo momento para situarse perpendicular al sol, cambiando dicha transmisión la posición del conjunto de paneles al unísono, tanto en lo que a su orientación lateral como de inclinación se refieren. Cada uno de los postes presenta por el interior un eje que en una zona intermedia comprende un acoplamiento mediante un tornillo sinfín o un medio similar, que transmite el movimiento de giro en la polea en un desplazamiento vertical del mismo, que a través de una biela superior modifica el grado de inclinación del panel, cuando a través del cable o cadena se procura la orientación de todos los paneles. Este sistema implica la existencia de un poste soporte con una estructura muy fuerte, y por tanto muy costosa, que ofrece una gran resistencia al viento.Document ES-1059590 describes an orientation device of a set of solar panels, each of which comprises a support post on which fixed a panel of photovoltaic panels, which has two axes of turn that independently control the angle that the panel form laterally and the inclination of it, being all panel posts joined by a mechanical transmission with a drive mechanism, which commanded by a single electronic microcontroller located in one of the panels, determine the position that it must have at all times to stand perpendicular to the sun, changing said transmission the position of the panel assembly in unison, both as far as its lateral orientation as of inclination refer. Each one of the posts have an axis inside that in an area intermediate comprises a coupling by means of an auger or a similar means, which transmits the turning movement in the pulley in a vertical displacement thereof, that through a connecting rod upper modifies the degree of inclination of the panel, when through the cable or chain the orientation of all panels. This system implies the existence of a support post with a very strong structure, and therefore very expensive, that offers a Great wind resistance.

Description of the invention

Se trata en la presente invención de una instalación de varios paneles dispuestos alineados horizontalmente, orientados al sur, y gobernados desde un actuador que los mueve al unísono girándolos lateralmente de este a oeste, como si de una persiana veneciana de inclinación lateral se tratase.In the present invention it is a installation of several horizontally arranged panels arranged, oriented to the south, and governed from an actuator that moves them to the unison turning them laterally from east to west, as if from a Venetian blind of lateral inclination be treated.

En el modelo de la presente invención cada uno de los paneles que componen una instalación de este tipo apoya, en la zona anterior-inferior en un soporte que en la base presenta una articulación, mientras que en la zona posterior apoya en un soporte telescópico y regulable en altura que permite modificar la inclinación del panel para su adecuación estacional. Ambos soportes están unidos superiormente por medio de un eje sobre el que apoya y gira el panel correspondiente, que varía su orientación este-oeste virtud al accionamiento que se efectúa sobre una biela que discurre por debajo del panel; de forma que al estar las distintas bielas, de los diversos paneles, unidas mecánicamente por una barra o elemento similar, se pueden desplazar por medio de un cilindro hidráulico o neumático situado en uno de los extremos de la instalación y en consecuencia inclinar al unísono el conjunto de paneles.In the model of the present invention each of the panels that make up such an installation support, in the anterior-inferior zone in a support than in the base presents a joint, while in the posterior area supports on a telescopic and height-adjustable stand that allows modify the inclination of the panel for seasonal adaptation. Both supports are connected superiorly by means of an axis on the one that supports and turns the corresponding panel, which varies its east-west orientation under the drive that it is made on a connecting rod that runs under the panel; from so that being the different connecting rods, of the various panels, mechanically joined by a bar or similar element, they can be move by means of a hydraulic or pneumatic cylinder located at one end of the installation and consequently tilt in unison the set of panels.

Se trata por tanto de un sistema en el que varios paneles se mueven al unísono orientándose en sentido este-oeste, con un único seguidor electrónico; mientras que la inclinación estacional se efectúa normalmente de forma tomando como referencia una inclinación media, o se modifica manualmente de forma periódica. A diferencia con los paneles subdivididos en láminas verticales que se inclinan como se de una persiana veneciana se tratase, se trata realmente de varios paneles alineados horizontalmente, con lo cual el movimiento uniforme se efectúa de forma muy simple y su estructura es mucho menos aparatosa que otras instalaciones. Con respecto a los paneles que presentan un eje vertical hueco en el que gira el eje del panel tampoco guarda ningún parecido, en primer lugar porque se trata de subdividir este panel en varios mucho más pequeños, de forma que las fuerzas del viento se dividen y minimizan sustancialmente, con lo cual la estructura soporta también se minimiza y simplifica.It is therefore a system in which several panels move in unison oriented in the direction east-west, with a single electronic follower; while the seasonal inclination is normally made of form taking as reference a medium inclination, or is modified manually periodically. Unlike with the panels subdivided into vertical sheets that lean as if from a Venetian blinds were, it is really several panels aligned horizontally, whereby the uniform movement is it performs very simply and its structure is much less aparatosa than other facilities. With respect to the panels that they have a hollow vertical axis where the panel axis rotates it also doesn't keep any resemblance, first of all because it's about subdivide this panel into several much smaller ones, so that wind forces are divided and minimized substantially, with which the structure supports is also minimized and simplified.
