Description

Seguidor solar para central eléctrica fotovoltaica, perfeccionado.Solar tracker for power plant photovoltaic, perfected.

Objeto de la invenciónObject of the invention

La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a un seguidor solar para central eléctrica fotovoltaica, perfeccionado, y como tal comporta características relevantes y ventajosas respecto de los que se construyen actualmente y son de su mismo tipo.The present invention, as expressed by the set forth in this specification, refers to a follower solar for photovoltaic power plant, perfected, and as such involves relevant and advantageous characteristics with respect to those that are currently built and are of the same type.

Antecedentes de la invenciónBackground of the invention

Las centrales eléctricas de placas solares que se construyen actualmente, la forman series de células fotoeléctricas ubicadas de forma fija, es decir, que se mantienen en una misma posición que es la más adecuada para captar los rayos solares a una determinada hora del día, cuando éstos inciden perpendicularmente. El rendimiento es pequeño al no aprovechar totalmente la acción solar.The solar panel power plants that They are currently built, the series of cells photoelectric located in a fixed way, that is, they are maintained in the same position that is best suited to capture the rays solar at a certain time of day, when they affect perpendicularly. Performance is small by not taking advantage Totally solar action.

También se han montado sin éxito por su elevado coste, unas placas solares en pequeño número, las cuales pueden oscilar alrededor de un eje vertical al que están vinculadas. Para que el rendimiento sea suficiente para la instalación de este tipo de placas es necesario montar un elevado número de dispositivos giratorios con sus respectivos motorreductores, lo que encarece notablemente la instalación.They have also been mounted unsuccessfully because of their high cost, solar panels in small numbers, which can oscillate around a vertical axis to which they are linked. For that the performance is sufficient for the installation of this type of plates it is necessary to mount a large number of devices rotating with their respective gearmotors, which makes it more expensive notably the installation.

En el Modelo de Utilidad nº 200103096, uno de cuyos solicitantes es el mismo de la presente invención, se contempla un seguidor solar que consigue aprovechar el máximo de la energía solar al contar con paneles solares que se encuentran constantemente orientados en acimut y elevación respecto al Sol, haciendo un seguimiento a lo largo del día y dependiendo también de la estación del año, mediante motorreductores gobernados por un autómata programable.In Utility Model No. 200103096, one of whose applicants are the same as the present invention, contemplate a solar tracker that manages to take full advantage of the solar energy by having solar panels that are constantly oriented in azimuth and elevation with respect to the Sun, tracking throughout the day and also depending on the season of the year, by means of geared motors governed by a programmable automata.

Esto se consigue con una plataforma horizontal fija al suelo y que cuenta con un carril circular elevado, quedando perfectamente nivelada mediante puntales. Sobre esta plataforma se encuentra otra giratoria dotada de ruedas y en cuya estructura existe un bastidor con una cierta angulación o disposición en rampa, en el que están tendidos horizontalmente una pluralidad de ejes a los que están fijadas sendas alineaciones de placas solares que pueden orientarse desde la posición vertical hasta la de máxima angulación al mediodía cuando el Sol está en lo más alto, recuperando la posición vertical al anochecer y quedando así preparadas para iniciar otro nuevo ciclo.This is achieved with a horizontal platform fixed to the ground and which has an elevated circular rail, remaining perfectly leveled by struts. On this platform find another swivel equipped with wheels and whose structure there is a frame with a certain angulation or arrangement in ramp, in which a plurality of horizontally laid axes to which solar plate alignments are attached which can be oriented from the vertical position to the maximum position  angulation at noon when the sun is at the top, recovering the vertical position at dusk and thus remaining ready to start another new cycle.

Existe un mecanismo de giro simultáneo de todos los ejes horizontales.There is a mechanism of simultaneous rotation of all the horizontal axes.

El giro en acimut se consigue mediante un motorreductor acoplado a una de las ruedas, girando hasta 210º ó 14 horas del recorrido solar aparente, desde la salida del sol hasta el ocaso, regresando por la noche a la posición inicial para quedar preparado para otro ciclo.The azimuth turn is achieved by a gearmotor coupled to one of the wheels, turning up to 210º or 14 hours of apparent solar travel, from sunrise to the sunset, returning at night to the starting position to stay Prepared for another cycle.

Se ha comprobado que puede mejorarse el movimiento de orientación de las placas optimizando y simplificando el funcionamiento y la estructura de soporte.It has been proven that the plate orientation movement optimizing and simplifying Operation and support structure.

Descripción de la invenciónDescription of the invention

En líneas generales, el seguidor solar para central eléctrica fotovoltaica, perfeccionado, objeto de la invención, se encuentra mejorado básicamente en la estructura móvil de instalación de las placas solares, eliminando tantos ejes horizontales de giro de las mismas como hemos comentado en el apartado anterior.In general, the solar tracker for photovoltaic power station, perfected, object of the invention, is basically improved in the mobile structure of installation of solar panels, eliminating so many axes horizontal rotation of the same as we have commented in the previous section.

Conforme a la invención, todas las placas quedan coplanarias y montadas fijas en ventajosamente dos grandes paneles, o un panel dividido en dos mitades, siendo esta única superficie captora de la luz solar la que es orientable al girar alrededor de un eje horizontal, desde la posición vertical hasta la de máxima angulación y viceversa.According to the invention, all plates remain  co-planar and fixed mounted advantageously in two large panels, or a panel divided into two halves, this being unique surface area that captures sunlight, which is rotatable around a horizontal axis, from the vertical position to the of maximum angulation and vice versa.

Esto se consigue el estar las placas solares dispuestas en dos paneles coplanarios que giran en un eje horizontal central a la superficie. El eje está sustentado en una estructura robusta de barras que conforman la plataforma superior giratoria.This is achieved by being solar panels arranged in two coplanar panels that rotate on one axis Central horizontal to the surface. The axis is supported in a robust structure of bars that make up the upper platform swivel

El giro de los paneles se consigue a través de motores eléctricos independientes y giran simultáneamente para ir adaptando su orientación a la posición aparente del sol, a través de mecanismos respectivos de husillo-tuerca.The rotation of the panels is achieved through independent electric motors and turn simultaneously to go adapting its orientation to the apparent position of the sun, through of respective spindle-nut mechanisms.

La estructura que rigidiza los propios paneles está equilibrada respecto del eje de giro de los mismos y materializa una disposición prismático triangular de perfiles con cerchas, tirantes y correas dispuestas entre ellas.The structure that stiffens the panels themselves is balanced with respect to their axis of rotation and it materializes a triangular prismatic arrangement of profiles with trusses, braces and straps arranged between them.
