Description
Elemento de soporte y protección de dispositivos de aprovechamiento solares.Device support and protection element of solar utilization.
Tal y como su nombre indica la presente invención consiste en un elemento de soporte y protección para dispositivos de aprovechamiento solar como pueden ser paneles, placas y colectores solares que, de forma automatizada, los cubre o descubre resguardándolos ante elementos adversos como lluvia, granizo, polvo o excesivo calor favoreciendo de ese modo el buen funcionamiento de los mismos y prolongando su vida.As its name indicates this invention consists of a support and protection element for solar devices such as panels, solar panels and collectors that, automatically, cover them or discover protecting them against adverse elements such as rain, hail, dust or excessive heat thereby favoring good operation of them and prolonging their life.
El sector de la técnica en el cual se ubica es el de los sistemas de instalación de dispositivos de aprovechamiento solar.The technical sector in which it is located is the device installation systems of solar utilization
La utilización de dispositivos que aprovechan la luz y el calor del sol para calentar agua o producir electricidad es algo de uso muy generalizado.The use of devices that take advantage of the light and heat from the sun to heat water or produce electricity It is very widespread use.
Para el mejor aprovechamiento de la energía solar tales elementos se suelen colocar a la intemperie en tejados, azoteas y otras zonas muy expuestas tanto a la acción solar como también a la humedad, calor, frío, viento, granizo, nieve, lluvia, polvo y demás elementos agresores.For the best use of energy solar such elements are usually placed outdoors on rooftops, roofs and other areas very exposed to both solar action and also to humidity, heat, cold, wind, hail, snow, rain, dust and other aggressive elements.
Además de las agresiones exteriores que pueden dañarlos, la exposición constante al sol provoca, sobre todo en verano, un recalentamiento de sus elementos internos y externos que, en ocasiones, puede llegar a dañar el equipo y que, a la larga, generan una disminución de la vida útil de los mismos.In addition to the external aggressions that can damage them, constant exposure to the sun causes, especially in summer, an overheating of its internal and external elements which, on occasion, may damage the equipment and, long, they generate a decrease in their useful life.
Por otro lado, en zonas frías, puede depositarse sobre los mismos una capa de nieve o hielo dejándolos inservibles mientras se mantiene el mencionado manto helado.On the other hand, in cold areas, it can be deposited on them a layer of snow or ice leaving them unusable while maintaining the aforementioned frozen mantle.
Una de las formas de proteger los dispositivos de aprovechamiento solar es cubriendo los mismos, operación que resulta complicada al estar situados, por lo general, en zonas de difícil acceso y peligrosas por su escasa estabilidad.One of the ways to protect the devices of solar use is covering the same, operation that it is complicated to be located, generally, in areas of difficult to access and dangerous because of its poor stability.
Por otro lado, la complejidad de cubrir las placas es mayor aún si se desea que, entre la placa propiamente dicha y el elemento que la cubre, quede una cámara de aire que favorezca el aislamiento de la misma.On the other hand, the complexity of covering the plates is even greater if it is desired that, between the plate itself said and the element that covers it, is an air chamber that favor the isolation of it.
Para solventar los problemas expuestos se ha desarrollado un elemento soporte para placas y paneles solares que incluye un soporte fijo en donde se encuentra alojada la placa o panel al que se le han incorporado una serie de raíles que discurren tanto por la parte inferior como por la superior de dicha placa y que son recorridos por un cuerpo flexible de una extensión similar a la superficie de la placa y que, cuando se encuentra sobre esta la cubre y protege y cuando se encuentra bajo la misma, refleja los rayos solares provocando de este modo que la placa o panel solar reciba una doble aportación de energía al recibirla tanto directamente del sol, en su cara superior, como del reflejo generado por la cara interna del cuerpo laminar en posición inferior.To solve the exposed problems it has been developed a support element for solar panels and panels that includes a fixed support where the plate is housed or panel to which a series of rails have been incorporated that they run through both the lower and the upper part of said plate and that are traversed by a flexible body of an extension similar to the surface of the plate and that, when found it covers and protects it and when it is under it, reflects the sun's rays thereby causing the plate or solar panel receive a double contribution of energy upon receipt both directly from the sun, on its upper face, and from the reflection generated by the inner face of the laminar body in position lower.
La invención que se propone consiste esencialmente en un soporte para dispositivos de aprovechamiento solar al cual se le incorporan una serie de raíles que lo recorren en toda su longitud por sus laterales a cierta distancia tanto por su parte superior como por la inferior.The proposed invention consists of essentially on a support for harvesting devices solar to which a series of rails that run through it are incorporated along its length along its sides at a distance both by its upper part as the lower part.
Por estos raíles discurre un cuerpo laminar que puede venir constituido de una sola pieza de material flexible, por ejemplo una pieza textil o geotextil, o bien a base de distintas piezas de material rígido unidas entre si formando una cubierta.A laminar body runs along these rails that It may be made of a single piece of flexible material, by example a textile or geotextile piece, or based on different pieces of rigid material joined together forming a cover.
Dicho cuerpo laminar se desplaza por los raíles siendo su recorrido continuo desde una posición superior, esencialmente cubriendo a determinada distancia la superficie de la placa, panel o colector solar, hasta una posición inferior, quedando bajo el dicho elemento solar tras girar de forma forzada para salvar la arista del propio dispositivo que circunvala.Said laminar body moves along the rails being its continuous route from a superior position, essentially covering the surface of the plate, panel or solar collector, to a lower position, remaining under the said solar element after turning in a forced way to save the edge of the device that circles it.
Para desplazar el cuerpo laminar a lo largo de los raíles se utiliza la fuerza motriz de un motor que transmite el movimiento al cuerpo laminar por cualquiera de las formas convencionales como engranajes o correas.To move the laminar body along the rails the driving force of an engine that transmits the laminar body movement in any of the ways conventional like gears or belts.
Este motor se activa de forma automática en función de los datos que recibe de una serie de sensores que detectan la temperatura del interior del dispositivo de aprovechamiento solar o bien la presencia o ausencia de sol.This engine is automatically activated in function of the data it receives from a series of sensors that detect the temperature inside the device solar use or the presence or absence of sun.
De este modo, partiendo de una posición de uso del dispositivo solar en donde este se encuentra descubierto estando el elemento protector bajo el mismo, en caso de ser detectado por uno de los sensores una elevada temperatura en su interior o superficie el motor se activaría para mover el cuerpo laminar hasta una posición superior que cubriera dicha placa o colector, y lo mismo sucedería en caso de ausencia de luz suficiente, quedando de este modo protegida la placa o colector tanto en situaciones de extremo calor o en los momentos de no uso.In this way, starting from a position of use of the solar device where it is discovered the protective element being under it, if it is a high temperature detected in one of the sensors inside or surface the engine would be activated to move the body laminate to a top position that covers said plate or collector, and the same would happen in case of absence of light sufficient, thus protecting the plate or collector both in extreme heat situations or in times of no use.
Estos mismos sensores de temperatura y luz detectarán las condiciones favorables para el uso de las placas o colectores activando el motor para que el elemento protector se posicione bajo la placa o colector.These same temperature and light sensors will detect favorable conditions for the use of the plates or collectors activating the motor so that the protective element is position under the plate or manifold.
En esta posición inferior la función del elemento protector sería distinta ya que dicho elemento puede venir realizado en un material o recubierto de un material, al menos en su cara interna, que facilite la reflexión de los rayos solares con lo cual se generaría un doble impacto de los rayos solares sobre el dispositivo de aprovechamiento solar que recibiría por una de sus caras directamente los rayos del sol y, por la otra, el reflejo de los mismos, optimizándose de ese modo el aprovechamiento de este tipo de dispositivos.In this lower position the function of protective element would be different since that element may come made of a material or coated with a material, at least in its inner face, which facilitates the reflection of solar rays with which would generate a double impact of the sun's rays on the solar utilization device that you would receive for one of your faces directly the sun's rays and, on the other, the reflection of the same, thus optimizing the use of this type of devices
En su función protectora, es decir cuando el elemento laminar protector se encuentra sobre la placa o colector solar, la placa queda también protegida de fenómenos atmosféricos como nieve o hielo resultando ventajoso en ese caso que se le dote por su cara externa de una serie de pestañas que favorezcan la retención y, en su momento, arrastre de la nieve o hielo.In its protective function, that is when the protective laminar element is located on the plate or collector solar, the plate is also protected from atmospheric phenomena like snow or ice proving advantageous in that case by its external face of a series of eyelashes that favor the retention and, at the time, dragging of snow or ice.
Para la mejor comprensión de lo que se expone se presentan las siguientes figuras junto con sus oportunas explicaciones.For the best understanding of what is exposed, present the following figures along with their appropriate explanations
La Figura 1 muestra una perspectiva de una de las posibles ejecuciones de la invención en posición de uso en donde se ve el elemento protector (1) en posición inferior bajo el dispositivo de aprovechamiento solar (2) que, tal y como se aprecia posee en sus laterales una serie de raíles en forma de "U" horizontal (3) que la recorren tanto superior como inferiormente y por los cuales discurre el elemento protector (1), estando movido dicho elemento protector por un motor (4) que se activa cuando una serie de sensores (5) detectan determinadas alteraciones de las condiciones internas o externas de la placa y remiten tales datos a un procesador. La cara interna del elemento protector (10) se encuentra realizada o recubierta de un material capaz de reflejar los rayos solares, provocando de ese modo un doble impacto sobre la placa, panel o colector.Figure 1 shows a perspective of one of the possible executions of the invention in position of use in where the protective element (1) is seen in the lower position under the solar utilization device (2) which, as seen it has a series of "U" shaped rails on its sides horizontal (3) that run it both top and bottom and through which the protective element (1) runs, being moved said protective element by a motor (4) that is activated when a series of sensors (5) detect certain alterations of the internal or external conditions of the board and send such data to a processor The inner face of the protective element (10) is is made or covered with a material capable of reflecting the sun's rays, thereby causing a double impact on the plate, panel or collector.
La Figura 2 reproduce otra posible ejecución de la invención mostrándola esta vez en posición de no uso encontrándose el elemento protector (6), sobre el dispositivo de aprovechamiento solar. Las guías en forma de "U" horizontal (3) que se muestran en la Figura 1 han sido sustituidas por juegos de raíles independientes el superior (7) del inferior (8) consiguiéndose la continuidad del recorrido gracias a un rodillo (9) que forzará al cuerpo laminar a girar y circunvalar parcialmente al dispositivo de aprovechamiento solar pasando desde la parte inferior del panel o placa hasta la superior o a la inversa, todo ello según se active el motor en función de los datos que los sensores (5) suministren a un procesador.Figure 2 reproduces another possible execution of the invention showing it this time in non-use position the protective element (6) being located on the device solar utilization The horizontal "U" shaped guides (3) shown in Figure 1 have been replaced by games of independent rails the superior (7) of the inferior (8) achieving continuity of the route thanks to a roller (9) that will force the laminar body to rotate and ring partially to the solar harvesting device going from the bottom of the panel or plate to the top or to the inverse, all according to the motor is activated based on the data that the sensors (5) supply to a processor.
Se expone a continuación una forma de llevar a cabo la invención ello sin perjuicio de que puedan sustituirse determinados dispositivos por otros que cumplan una función similar.A way of bringing carry out the invention without prejudice to their replacement certain devices by others that fulfill a function Similary.
La presente invención comprende esencialmente un soporte para el dispositivo de aprovechamiento solar al cual van sujetos, en sus laterales, sendos raíles en forma de "U" dispuesta en horizontal de tal modo una de las prolongaciones de dicha "U" discurre a mayor altura que la placa y la otra a una altura inferior.The present invention essentially comprises a support for the solar harvesting device to which they go subjects, on their sides, two "U" shaped rails horizontally arranged in such a way one of the extensions of said "U" runs higher than the plate and the other at a lower height.
Los mencionados raíles sirven de guía para que se desplace un cuerpo laminar, bien realizado de una sola pieza de material flexible como puede ser un material geotextil o bien venir compuesto de una serie de lamas unidas entre sí al modo de una persiana.The mentioned rails serve as a guide for a laminar body is moved, well made of a single piece of flexible material such as a geotextile material or come composed of a series of slats joined together in the manner of a blind.
Dicho cuerpo laminar, que servirá de elemento protector del dispositivo de aprovechamiento solar es de una superficie similar al de este.Said laminar body, which will serve as an element sunscreen device protector is of a surface similar to this one.
La carrera de dicho cuerpo laminar al desplazarse por los raíles viene definida desde una posición superior en la que se encontraría cubriendo el dispositivo solar durante los periodos de no uso del mismo hasta una posición inferior, durante los plazos de uso del dispositivo, en la quedaría bajo este y viceversa.The laminar body's career at moving along the rails is defined from a position top where it would be covering the solar device during periods of non-use of it until a position lower, during the terms of use of the device, in the under this and vice versa.
Este movimiento de desplazamiento por los raíles desde una posición superior a una inferior se consigue gracias a la acción de un motor y la aplicación de una serie de engranajes y/o tirantes convencionales.This movement of movement along the rails from a superior position to a lower one it is achieved thanks to the action of an engine and the application of a series of gears and / or conventional braces.
La activación de motor en cada momento para desplazar el elemento protector desde una posición, por ejemplo inferior, a otra, por ejemplo superior o viceversa, viene determinada por la actuación de un procesador que, en función de los datos que le suministran una serie de sensores se activará provocando el traslado del cuerpo laminar de uno a otro extremo de su recorrido.Engine activation at any time to move the protective element from a position, for example inferior, to another, for example superior or vice versa, comes determined by the performance of a processor that, depending on the data that you supply a series of sensors will be activated causing the transfer of the laminar body from one end of its route.
Los sensores señalados detectarán esencialmente los datos relativos a la temperatura en el interior o superficie de la placa, panel o colector así como la intensidad de luz existente en cada momento.The indicated sensors will essentially detect data relating to the temperature inside or surface of the plate, panel or collector as well as the existing light intensity in every moment.
Si la temperatura en el dispositivo solar aumenta en exceso, el protector pasará a una posición superior para cubrirlo y evitar de ese modo que pudiera dañarse.If the temperature in the solar device increases in excess, the protector will move to a higher position to cover it and prevent it from being damaged.
Igualmente, si la luz existente resultara ya insuficiente hasta el extremo de no ser útil para su aprovechamiento por el dispositivo solar, el elemento protector pasará a su posición superior para cubrirlo durante los periodos de no aprovechamiento.Likewise, if the existing light were already insufficient to the point of not being useful for your use by the solar device, the protective element will go to its upper position to cover it during periods of no use
Cuando los sensores determinen que la temperatura del dispositivo solar es la adecuada y la luz de incidencia es aprovechable, el elemento protector pasará a una posición inferior dejando que la placa, panel o colector solar reciba el impacto de los rayos del sol.When the sensors determine that the solar device temperature is adequate and the light of incidence is usable, the protective element will pass to a bottom position letting the solar panel, panel or collector receive the impact of the sun's rays.
En esta posición de uso, la incidencia de los rayos solares sobre el dispositivo solar se potencia gracias a que, al menos la cara interna del elemento protector se encuentra realizada o recubierta de un material capaz de reflejar los rayos solares de tal forma que estos inciden en el dispositivo solar tanto directamente sobre su cara superior como indirectamente gracias al reflejo en su cara inferior.In this position of use, the incidence of solar rays on the solar device is enhanced because, at least the inner face of the protective element is made or covered with a material capable of reflecting the rays solar so that these affect the solar device both directly on your upper face as indirectly thanks to the reflection in its lower face.
