Abstract
Description
Seguidor solar a dos ejes, sobre plataforma rodante de tres apoyos verticales y uno horizontal.Two-axis solar tracker, on platform Three vertical supports and one horizontal.
La presente invención se refiere a un seguidor solar, con sistema de orientación en dos ejes perpendiculares y sustentación mediante plataforma rodante sobre superficie horizontal.The present invention relates to a follower solar, with orientation system in two perpendicular axes and lift via surface-mounted rolling platform horizontal.
La peculiaridad del seguidor estriba en el sistema de sustentación elegido, que se realiza por medio de una estructura portante en forma triangular, con sustentación mediante tres ruedas (una en cada vértice del triángulo) y giro del conjunto alrededor de un eje central que recibe los esfuerzos horizontales. El sistema garantiza el permanente contacto de las ruedas con el pavimento sin introducir esfuerzos o deformaciones en la estructura, lo que hace que el conjunto tenga una gran estabilidad, permitiendo por tanto realizar seguidores de gran tamaño de una forma sencilla y segura.The peculiarity of the follower lies in the chosen lift system, which is done by means of a supporting structure in triangular form, with support by three wheels (one at each vertex of the triangle) and set rotation around a central axis that receives horizontal stresses. The system guarantees the permanent contact of the wheels with the pavement without introducing stresses or deformations in the structure, which makes the whole have great stability, allowing therefore make large followers in a simple and safe.
La alineación de un equipo con un astro está resuelta desde hace tiempo con los distintos tipos de monturas que existen para los telescopios utilizados en astronomía.The alignment of a team with a star is solved for a long time with the different types of mounts that they exist for telescopes used in astronomy.
Los seguidores existentes en el mercado, al igual que los telescopios, utilizan dos sistemas de alineación: Ecuatorial (con uno de sus ejes paralelo al de la Tierra) y altacimutal (cuando uno de sus ejes es coincidente con la vertical del lugar).The existing followers in the market, at Like telescopes, they use two alignment systems: Equatorial (with one of its axes parallel to that of the Earth) and altacimutal (when one of its axes is coincident with the vertical of the place).
Cuando el seguidor empieza a tener un cierto tamaño, el sistema que se utiliza es el altacimutal por ser mas sencilla y fiable la ejecución del conjunto. Los seguidores existentes en general resuelven bien la sustentación de cargas verticales y no así la transmisión de cargas horizontales (carga de viento), por no disponer de una base lo suficiente amplia para disminuir los esfuerzos que se originan en el eje vertical.When the follower starts to have a certain size, the system used is the altacimutal for being more simple and reliable execution of the set. The followers existing in general solve the load bearing well vertical and not the transmission of horizontal loads (load of wind), for not having a base wide enough to decrease the stresses that originate on the vertical axis.
Para resolver este problema se propuso colocar el conjunto del seguidor sobre una plataforma rodante, según modelo de utilidad U-200502495. A continuación se desarrollo como aplicación directa de dicho modelo una estructura de 4 apoyos exteriores y otro central, según modelo U-200602200, ambos del mismo inventor (Justino Magán de la Rocha).To solve this problem it was proposed to place the follower assembly on a rolling platform, depending on the model of utility U-200502495. Then you development as a direct application of said model a structure of 4 external supports and another central one, according to model U-200602200, both of the same inventor (Justin Magán de la Rocha).
En el desarrollo del último modelo se han detectado los siguiente problemas:In the development of the latest model they have Detected the following problems:
- Al ser 4 el número de ruedas y tener irregularidades el pavimento, la distribución de cargas sobre las ruedas no es uniforme y se producen torsiones en la estructura.- Being 4 the number of wheels and have irregularities the pavement, the distribution of loads on the Wheels are not uniform and twists occur in the structure.
- La disposición del apoyo central recibiendo esfuerzos verticales introduce flexión en la viga puente central que llega a levantar las ruedas (en definitiva, el sistema cojea).- The provision of central support receiving vertical forces introduces bending in the central bridge beam that gets to lift the wheels (in short, the system limps)
El seguidor que ahora se propone tiene resueltos ambos problemas.The follower who is now proposed has resolved both problems
El seguidor solar objeto de la invención cuenta con una estructura soporte sobre tres ruedas que giran en un plano horizontal alrededor de un eje vertical en el centro. Sobre esta estructura soporte se coloca un eje horizontal que en sus giro mueve los paneles en un plano vertical. La combinación de ambos giros posibilita la alineación constante de los paneles con el sol.The solar tracker object of the invention counts with a support structure on three wheels that rotate in a plane horizontal around a vertical axis in the center. About this support structure is placed a horizontal axis that in its turn Move the panels in a vertical plane. The combination of both turns allows the constant alignment of the panels with the Sun.
La estructura soporte se compone de dos cerchas en "V" sobre las que se coloca una viga puente formando un triángulo con extremos en voladizo y en los que se sitúan las ruedas soporte. Para absorber los esfuerzos horizontales se coloca una semicercha en el centro del triángulo, que pasando por el apoyo central llega hasta la viga puente en su punto medio.The support structure consists of two trusses in "V" on which a bridge beam is placed forming a triangle with cantilever ends and on which the wheels are located support. To absorb the horizontal forces, a semi-right in the center of the triangle, which goes through the support Central reaches the bridge beam at its midpoint.
El giro del conjunto alrededor del eje central se produce mediante ruedas motorizadas en los extremos de la estructura soporte, que circulando por un carril circular consiguen la orientación en azimut del seguidor. El apoyo central dispone de un rodamiento deslizante, de forma que en condiciones normales solo recibe esfuerzos horizontales. Para el caso de fuertes vientos se cuenta con un tope superior en dicho apoyo de forma que impide el vuelco del conjunto.The rotation of the assembly around the central axis is produced by motorized wheels at the ends of the support structure, which circulate through a circular rail get the azimuth orientation of the follower. The central support has a sliding bearing, so that in normal conditions only Receive horizontal efforts. In the case of strong winds, it has a top stop on said support in a way that prevents overturn of the set.
Sobre la viga puente se coloca un eje horizontal que tiene correas transversales, adoptando forma en "espina de pez", y sobre las cuales se colocarán los paneles solares. Para la orientación en altitud de los paneles, el eje tiene en su centro una manivela, que se accionan por medio de un sistema de tornillo sinfín desde la plataforma. Para seguidores de gran tamaño, el eje horizontal se divide en varios tramos, de forma que cada uno solo se tenga dos apoyos.A horizontal axis is placed on the bridge beam which has transverse straps, taking shape in "spine of fish ", and on which the solar panels will be placed. the orientation in altitude of the panels, the axis has in its center a crank, which are operated by means of a screw system Endless from the platform. For large followers, the axis horizontal is divided into several sections, so that each one only You have two supports.
El seguidor contará con una automatización en su movimientos de giro sobre los dos ejes, con inicio en la salida del Sol y final en la puesta del mismo, momento en el que vuelve a la posición inicial en sentido inverso al seguido durante el día, y quedando parado hasta la salida del sol del día siguiente.The follower will have an automation in his turning movements on the two axes, starting at the exit of the Sun and end in the sunset, when he returns to the initial position in the opposite direction to the one followed during the day, and standing until sunrise the next day.
Se utilizará un programa estándar para estos movimientos, basado en los programas de orientación automática de los telescopios, en los que ejecutando la función "GO TO" con la frecuencia que se quiera realinear el sistema, se obtienen los valores de los ángulos de alineación del Sol.A standard program will be used for these movements, based on the automatic orientation programs of the telescopes, in which executing the "GO TO" function with the frequency that you want to realign the system, you get the values of the alignment angles of the Sun.
