Description
SEGUIDOR SOLAR PLEGABLE Y PROCEDIMIENTO DE OPERACIÓN FOLDING SOLAR FOLLOWER AND OPERATION PROCEDURE
La presente memoria descriptiva se refiere, como su título indica, a un seguidor solar plegable caracterizado porque la estructura de soporte de los paneles fotovoltaicos es plegable, reduciéndose su extensión a la mitad, y está ubicada sobre una estructura de soporte sobre el suelo asimismo plegable, disponiendo de un motor de regulación acimutal y de una estructura de elevación basada en un doble paralelogramo que regula la inclinación de la estructura de soporte de los paneles fotovoltaicos durante su orientación, además de permitir su posicionamiento completamente recogido. The present specification refers, as its title indicates, to a foldable solar tracker characterized in that the support structure of the photovoltaic panels is foldable, reducing its extension in half, and is located on a support structure on the ground also foldable , having an azimuth regulation motor and a lifting structure based on a double parallelogram that regulates the inclination of the support structure of the photovoltaic panels during their orientation, in addition to allowing their fully collected positioning.
En la actualidad son ampliamente conocidos múltiples y variados tipos de seguidores solares. La mayor parte corresponden a estructuras fijas, como por ejemplo la descrita en el Modelo de Utilidad 200700534 "Seguidor solar a dos ejes sobre plataforma rodante", cuya única posibilidad de movimiento es la propia de la orientación, necesitando de una gran trabajo para su transporte, montaje y puesta en operación, no siendo económicamente rentable su transporte a otras ubicaciones debido al alto coste de montaje. At present, multiple and varied types of solar trackers are widely known. Most of them correspond to fixed structures, such as the one described in Utility Model 200700534 "Two-axis solar tracker on rolling platform", whose only possibility of movement is that of the orientation, needing a great job for transport , assembly and commissioning, not being economically profitable transport to other locations due to the high cost of assembly.
Sin embargo, existen multitud de situaciones en las que se necesita una fuente generadora de energía eléctrica fácilmente transportable y montable en un sitio durante un tiempo. Para ello hasta ahora son comúnmente utilizados auto-generadores basados en motores de explosión, que tienen el problema de ser contaminantes, además de grandes, pesados y ruidosos. Se han intentado algunas realizaciones que faciliten el uso de tecnología solar de una forma más transportable, como por ejemplo podemos encontrar la Patente ES 200800386 "Seguidor torregiro" que está formado por perfiles y uniones desmontables, a modo de mecano, o bien la Patente ES 200700836 "Seguidor solar" que presenta un dispositivo desmontable, con unos largueros de soporte plegables a modo de paraguas, pero siguen sin constituir un módulo verdaderamente compacto y transportable, limitándose a facilitar ligeramente las labores de montaje y desmontaje, que siguen teniendo que ser realizadas por personal técnico especializado, y con una duración de tiempo todavía extensa. However, there are many situations in which a source of electricity that is easily transportable and mountable at a site is needed for a time. To this end, auto-generators based on explosion engines are commonly used, which have the problem of being pollutants, as well as large, heavy and noisy ones. Some embodiments have been attempted that facilitate the use of solar technology in a more transportable way, as for example we can find the ES Patent 200800386 "Torregiro follower" which is formed by profiles and removable joints, as a mechano, or the ES Patent 200700836 "Solar tracker" presenting a Detachable device, with folding support rails as an umbrella, but they still do not constitute a truly compact and transportable module, merely facilitating the assembly and disassembly tasks, which still have to be carried out by specialized technical personnel, and with a duration of time still extensive.
Para solventar la problemática existente en la actualidad en el transporte de paneles solares se ha ideado el seguidor solar plegable objeto de la presente invención, el cual tiene una estructura de soporte de los paneles fotovoltaicos plegable, reduciéndose su extensión a la mitad. El anclaje al suelo se realiza mediante una estructura de soporte sobre el suelo asimismo plegable, conformada por una pluralidad de brazos, terminados en ejes para clavar o ruedas autoextensibles que le confieren una gran estabilidad y segundad de operación sin necesidad de cimentaciones. To solve the problem currently in the transport of solar panels, the foldable solar tracker object of the present invention has been devised, which has a support structure of the foldable photovoltaic panels, reducing its extension by half. The anchorage to the ground is carried out by means of a support structure on the ground that is also foldable, consisting of a plurality of arms, finished in axles for nailing or self-extending wheels that give it great stability and second-hand operation without foundations.
El dispositivo dispone de un motor eléctrico de regulación acimutal y de una estructura de elevación basada en un doble paralelogramo que regula la inclinación de la estructura de soporte de los paneles fotovoltaicos durante su orientación, entre 0o y 60° además de permitir su posicionamiento completamente horizontal en la posición de plegado para reducir el volumen ocupado. Esta configuración de elevación permite que la estructura de soporte y los paneles solares se desplacen hacia adentro a la vez que se eleva variando su inclinación, lo cual propicia que la carga esté siempre centrada sobre el eje de giro acimutal, mejorando su estabilidad y su funcionamiento. The device has an electric motor azimuthal adjustment and an elevating structure based on a double parallelogram which regulates the inclination of the support structure of the photovoltaic panels for its orientation 0 or 60 ° and allows positioning completely horizontal in the folded position to reduce the volume occupied. This lifting configuration allows the support structure and the solar panels to move inwards while increasing its inclination, which allows the load to always be centered on the azimuthal axis of rotation, improving its stability and operation. .
Toda la estructura del dispositivo se realiza con tubos y perfiles huecos en materiales metálicos ligeros, por ejemplo aluminio, consiguiendo una gran ligereza del conjunto. The entire structure of the device is made with tubes and hollow profiles in light metallic materials, for example aluminum, achieving a great lightness of the whole.
En su interior alberga los oportunos dispositivos, como por ejemplo una batería eléctrica asociada con un inversor y un regulador de carga, junto con un dispositivo de orientación, que puede ser una brújula o bien un programador con posicionamiento GPS para controlar la correcta orientación del dispositivo, de tal manera que el funcionamiento del dispositivo es completamente autónomo, bastando su desplegado y orientación en un punto para poder disponer de energía. Inside it houses the appropriate devices, such as an electric battery associated with an inverter and a charge controller, together with an orientation device, which can be a compass or a programmer with GPS positioning to control the correct orientation of the device , such that the operation of the The device is completely autonomous, its deployment and orientation being sufficient at one point to be able to have energy.
El plegado y desplegado se realiza de forma manual mientras que la orientación, mediante giro acimutal y regulación de la inclinación de las placas solares, se realiza de forma eléctrica. The folding and unfolding is done manually while the orientation, by azimuthal rotation and regulation of the inclination of the solar panels, is done electrically.
Esta invención es particularmente útil para todas aquellas situaciones en las que se necesite un medio transportable de producción de energía, como por ejemplo en aplicaciones militares, campamentos itinerantes, zonas asoladas por catástrofes, camping, etc.. aunque también es aplicable en aquellas situaciones en las que, por seguridad o para evitar robos del equipo, es deseable poder recoger el dispositivo cuando no se va a utilizar durante un largo periodo de tiempo, como por ejemplo en segundas residencias, granjas, casa de campo, refugios, etc.. This invention is particularly useful for all those situations in which a transportable means of energy production is needed, such as in military applications, traveling camps, areas devastated by disasters, camping, etc ... although it is also applicable in those situations in which which, for safety or to prevent theft of the equipment, it is desirable to be able to pick up the device when it is not going to be used for a long period of time, such as in second homes, farms, country houses, shelters, etc.
Este seguidor solar plegable que se presenta aporta múltiples ventajas sobre los sistemas disponibles en la actualidad siendo la más importante que consigue un seguidor solar de dos ejes ligero y fácilmente transportable ya que en la posición de plegado ocupa un espació reducido, con unos tiempos de plegado y desplegado notablemente cortos, que propician su rápida utilización. This foldable solar tracker that is presented provides multiple advantages over the systems currently available, being the most important one that achieves a lightweight and easily transportable two-axis solar tracker since in the folding position it occupies a reduced space, with folding times and deployed remarkably short, which favor its rapid use.
Es importante destacar que la estructura de soporte sobre el suelo está conformada por una pluralidad de brazos lo cual confiere una gran estabilidad y seguridad de operación sin necesidad de cimentaciones utilizadas convencionalmente, o sin necesidad de fijarlo a la estructura de un edificio. It is important to note that the support structure on the ground is made up of a plurality of arms which confers great stability and safety of operation without the need for foundations conventionally used, or without the need to fix it to the structure of a building.
Otra ventaja de la presente invención es que la regulación de la inclinación mediante una doble estructura en paralelogramo de brazos desiguales permite mejorar la estabilidad del conjunto, ya que las placas solares siempre se mantendrán centradas sobre la estructura de soporte sobre el suelo. Otra de las más importantes ventajas a destacar es que la inclusión de todos los elementos necesarios, como batería, inversor, regulador de carga, programador con posicionamiento GP, etc.. permite conformar un dispositivo completamente autónomo, bastando su desplegado y orientación en un punto para poder disponer de energía. Another advantage of the present invention is that the adjustment of the inclination by means of a double parallelogram structure of unequal arms allows to improve the stability of the assembly, since the solar panels will always remain centered on the support structure on the ground. Another of the most important advantages to highlight is that the inclusion of all the necessary elements, such as battery, inverter, charge regulator, programmer with GP positioning, etc ... allows to form a completely autonomous device, basing its deployment and orientation in one point to be able to have energy.
Asimismo otra ventaja añadida es que su sencillez de operación permite su montaje, desmontaje y utilización incluso por personas sin especial formación en tecnologías solares, facilitando por tanto su uso. Also another added advantage is that its simplicity of operation allows its assembly, disassembly and use even by people without special training in solar technologies, thus facilitating its use.
Otra importante ventaja es que dado su tamaño tremendamente compacto en la posición de plegado requiere muy poco espacio para su almacenamiento, siendo susceptible de ser guardado por ejemplo en un garaje, furgoneta, contenedor, camión, etc. Another important advantage is that given its tremendously compact size in the folded position it requires very little storage space, being able to be stored for example in a garage, van, container, truck, etc.
Destacar asimismo la ventaja que supone de cara a la protección durante el almacenamiento o transporte que las caras fotosensibles de las placas fotovoltaicas se ubican una contra otra en la posición de plegado, protegiéndose del exterior. It should also be noted that it is advantageous for protection during storage or transport that the photosensitive faces of the photovoltaic panels are placed against each other in the folded position, protecting themselves from the outside.
Por último resaltar que este dispositivo presenta una alternativa válida y no contaminante, mucho más ligera, compacta y fácil de operar, frente a los actuales autogeneradores transportables de energía basados en motores alimentados por combustibles como gas-oil, gasolina, etc.. Finally, it should be noted that this device presents a valid and non-polluting alternative, much lighter, more compact and easy to operate, compared to current transportable energy self-generators based on engines fueled by fuels such as gas-oil, gasoline, etc.

Estos medios de giro (12) consisten preferentemente en una corona asociada con un motor eléctrico mediante el oportuno moto-reductor. The base (7) of the lifting structure is in turn related to a lower support structure (11) on the ground by means of rotation (12) that make up the vertical axis of rotation necessary for azimuthal movement. These turning means (12) preferably consist of a crown associated with an electric motor by means of the appropriate motor reducer.
La estructura inferior (11) de soporte sobre el suelo está formada por varias patas horizontalmente dispuestas solidarias entre sí permanentemente por su parte interior (13) y que disponen cada uno de un medio de giro (14) que propicia que las partes exteriores (15) pueda estar en una posición extendida, en la que dichas partes exteriores (15) quedan alineada como una prolongación de las partes interiores (13), mientras que en una posición de plegado cada parte exterior (15) forma un ángulo con su correspondiente parte interior (13), apoyando el extremo libre de las partes exteriores (15) en el medio de giro de (14) de la pata adyacente. Está prevista una realización alternativa de la estructura inferior (11) de soporte sobre el suelo que consta de unas patas (17) horizontalmente dispuestas y solidarías entre sí que disponen cada una en su interior de al menos una prolongación retráctil (18) extraíble de forma telescópica. The lower support structure (11) on the floor is formed by several horizontally arranged legs permanently connected to each other by their inner part (13) and each having a turning means (14) that favors that the outer parts (15 ) may be in an extended position, in which said outer parts (15) are aligned as an extension of the inner parts (13), while in a folding position each outer part (15) forms an angle with its corresponding inner part (13), the free end of the outer parts (15) resting on the turning means of (14) of the adjacent leg. An alternative embodiment of the lower support structure (11) on the ground is provided, which consists of horizontally arranged legs (17) and joined together, each having at least one retractable extension (18) removable in its interior. telescopic

Está previsto que la base (7) de la estructura de elevación albergue una batería eléctrica asociada con un inversor y un regulador de carga, junto con un dispositivo de orientación, que puede ser una brújula o bien un programador con posicionamiento GPS para controlar la correcta orientación del dispositivo. It is provided that the base (7) of the lifting structure houses an electric battery associated with an inverter and a charge controller, together with an orientation device, which can be a compass or a programmer with GPS positioning to control the correct device orientation.
Esta invención tiene un procedimiento característico de operación en el que primero se procede al despliegue posicionando primeramente al seguidor en el lugar elegido, prosiguiendo con la apertura de las patas de la estructura inferior (11) de soporte sobre el suelo, bien mediante el giro manual de las partes exteriores (15) hasta que queden alineadas como una prolongación de las partes interiores (13) o bien mediante la extracción de la prolongación retráctil (18) alojada en el interior de la pata (17), continuando con la apertura de los paneles mediante el giro manual de los extremos articulados (3) y de sus paneles fotovoltaicos (1) asociados, de tal forma que queden posicionados de forma adyacente al mismo nivel que los paneles fotovoltaicos (1) interiores. This invention has a characteristic operation procedure in which the deployment is first carried out by first positioning the follower in the chosen place, continuing with the opening of the legs of the lower support structure (11) on the ground, either by manual rotation of the outer parts (15) until they are aligned as an extension of the inner parts (13) or by removing the retractable extension (18) housed inside the leg (17), continuing with the opening of the panels by manually rotating the articulated ends (3) and their associated photovoltaic panels (1), so that they are positioned adjacent to the same level as the interior photovoltaic panels (1).
En este momento se puede proceder a orientación y producción de energía, realizando para ello la elevación, en la que los medios de elevación (9) eléctricamente accionados provocan la elevación de la estructura de soporte mediante los travesaños (4) que, merced al paralelogramo conformado por los brazos de diferente longitud (5,6) origina una variación en la inclinación en la estructura de soporte y por tanto en los paneles fotovoltaicos, y el giro acimutal, en la que los medios de giro (12) regulan la posición de la base (7) con respecto a la estructura inferior (11) de soporte sobre el suelo, para proceder a la generación de energía fotovoltaica manteniendo de forma continua la orientación e inclinación óptima hacia el sol mediante la actuación de los medios de elevación (9) y de los medios de giro (12) controlada por el programador con posicionamiento GPS. At this time, orientation and energy production can be carried out, carrying out the lifting, in which the electrically operated lifting means (9) cause the support structure to be lifted by the cross-members (4) which, thanks to the parallelogram conformed by the arms of different length (5,6) originates a variation in the inclination in the support structure and therefore in the photovoltaic panels, and the azimuthal rotation, in which the turning means (12) regulate the position of the base (7) with respect to the lower structure (11 ) of support on the ground, to proceed to the generation of photovoltaic energy continuously maintaining the orientation and optimal inclination towards the sun by means of the actuation of the lifting means (9) and the turning means (12) controlled by the programmer with GPS positioning.
Una vez finalizada la utilización del dispositivo, se puede proceder a su recogida, comenzando por el descenso de las placas fotovoltaicas (1) hasta su posición horizontal, mediante la actuación de los medios de elevación (9), continuando con el plegado de la estructura de soporte mediante el giro manual hacia el interior de los extremos articulados (3) y de sus paneles fotovoltaicos (1) asociados, de tal forma que queden posicionados sobre los paneles fotovoltaicos (1) interiores, para finalizar con el plegado de las patas de la estructura inferior (11) de soporte sobre el suelo bien mediante el giro manual de las partes exteriores (15) hacia el interior o bien mediante la introducción de la prolongación retráctil (18) en el interior de la pata (17). Ahora ya es posible su almacenamiento o su transporte a otra ubicación. Once the use of the device is finished, it can be collected, starting with the descent of the photovoltaic panels (1) to their horizontal position, by means of the lifting means (9), continuing with the folding of the structure of support by means of the manual turn towards the interior of the articulated ends (3) and of their associated photovoltaic panels (1), so that they are positioned on the interior photovoltaic panels (1), to end with the folding of the legs of the lower support structure (11) on the ground either by manually turning the outer parts (15) inwards or by introducing the retractable extension (18) inside the leg (17). Now it is possible to store or transport it to another location.
