Explicación de la invenciónExplanation of the invention.

El seguidor solar a dos ejes, dispone para el seguimiento de los rayos solares, y de manera perpendicular a los mismos, de al menos un plano de paneles solares formado por al menos un tablero, preferiblemente dos, sobre el que se monta o montan dichos paneles solares, y disponiendo dichos tableros de un movimiento de giro respecto a un eje vertical y un movimiento de giro respecto a un eje horizontal, siendo ambos ejes perpendiculares entre sí. Dicho eje vertical es fijo y el conjunto del seguidor solar rota respecto al mismo mientras que dicho eje horizontal posibilita el movimiento del tablero o tableros respecto al mismo. En el caso de dos tablero, el giro de los mismos respecto al eje horizontal puede ser de manera sincronizada, es decir, ambos tableros giran a la vez, o de manera independiente.The two-axis solar tracker, has for the tracking the sun's rays, and perpendicular to the same, of at least one plane of solar panels formed by the less a board, preferably two, on which it is mounted or they mount said solar panels, and arranging said panels of a rotation movement with respect to a vertical axis and a movement of rotation with respect to a horizontal axis, both axes being perpendicular to each other. Said vertical axis is fixed and the whole of the solar tracker rotates with respect to it while said axis horizontal enables the movement of the board or boards with respect the same. In the case of two boards, the rotation thereof to the horizontal axis can be synchronized, that is, both boards rotate at the same time, or independently.

Es por tanto, el objeto de la presente invención un seguidor solar a dos ejes que permite mantener la perpendicularidad de los paneles respecto a los rayos solares independientemente de la situación del sol, cambiante a lo largo de un día.It is therefore the object of the present invention a two-axis solar tracker that allows to maintain the perpendicularity of the panels with respect to the sunrays regardless of the situation of the sun, changing along one day.

El plano de paneles está formado por al menos un tablero, preferiblemente dos, que soportan los paneles solares, y que se sustentan sobre una estructura rodante que dispone de un eje vertical fijo centrado respecto a dicha estructura. El eje vertical central se encuentra fijado a una zapata de inmovilización de todo el conjunto.The panel of panels consists of at least one board, preferably two, that support the solar panels, and that are supported on a rolling structure that has an axis  fixed vertical centered with respect to said structure. The axis central vertical is fixed to an immobilization shoe of the whole set.

Los paneles solares van preferiblemente atornillados por sus marcos a un entramado de perfilería metálica soldada y atornillada, formando dichos entramados el correspondiente tablero o tableros.Solar panels preferably go screwed by their frames to a framework of metal profiles welded and screwed, forming said frameworks the corresponding board or boards.

En cada tablero o entramado de perfilería se realiza el eje horizontal que se dispone a su vez sobre el conjunto soporte o estructura rodante. El movimiento de giro del plano de tableros para el seguimiento del sol en elevación se realiza mediante accionamientos automatizados, por ejemplo motorreductores de mecanismo de tornillo sin fin, consiguiendo mediante este sistema el giro de los tableros y por tanto de los paneles sobre el eje horizontal con una fácil automatización para cada día y hora del año. Dichos accionamientos automatizados siendo independientes permiten que los tableros puedan girar sincronizadamente o de manera independiente entre si respecto al eje horizontal.On each board or grid framework, performs the horizontal axis that is arranged in turn on the set support or rolling structure. The turning movement of the plane of boards for tracking the rising sun is done by automated drives, for example gearmotors of endless screw mechanism, getting through this system the rotation of the boards and therefore of the panels on the horizontal axis with easy automation for every day and time of the year. These automated drives being independent allow the boards to rotate synchronously or of independent of each other with respect to the horizontal axis.

El sistema de soporte del citado eje horizontal es el eje vertical central así como la estructura rodante, formada por un conjunto estructural de vigas metálicas reticuladas multiarriostradas que descansan y apoyan sobre un plano horizontal (suelo, solera plana, viga de hormigón, perfil metálico, etc.) mediante ruedas, siendo unas de arrastre (motorizadas con motorreductores automatizados) y otras sólo de apoyo.The support system of said horizontal axis it is the central vertical axis as well as the rolling structure, formed by a structural set of crosslinked metal beams multi-braces that rest and rest on a horizontal plane (floor, flat screed, concrete beam, metal profile, etc.) by means of wheels, being ones of drag (motorized with automated gearmotors) and other support only.

Descripción de una forma preferente de realizaciónDescription of a preferred embodiment

El seguidor solar objeto de la presente invención, queda apoyado sobre un suelo, solera plana, o carril 1 y gira respecto a su eje vertical 2, que queda fijado al suelo a través de una zapata de inmovilización del conjunto.The solar tracker object of the present invention, is supported on a floor, flat hearth, or lane 1 and rotates with respect to its vertical axis 2, which is fixed to the ground at through a set immobilization shoe.

El seguidor solar queda soportado sobre una estructura rodante 3 y que gira respecto a dicho eje vertical 2, estando dicha estructura soporte 3 del seguidor solar compuesta de un conjunto estructural 3 de vigas metálicas reticuladas. Tal y como se puede observar en las figuras, en particular en la figura 6, secuencias A, B, C, D, H, I, J, la estructura soporte dispone de un saliente en su parte anterior a modo de nariz que aporta una gran estabilidad al conjunto estructural y por tanto al dispositivo solar.The solar tracker is supported on a rolling structure 3 and which rotates with respect to said vertical axis 2, said support structure 3 of the solar tracker being composed of a structural assembly 3 of crosslinked metal beams. So and as can be seen in the figures, in particular in the figure 6, sequences A, B, C, D, H, I, J, the support structure has a protrusion in its anterior part as a nose that provides a great stability to the structural assembly and therefore to the device solar.

El giro del seguidor solar respecto al eje vertical 2 se consigue mediante el uso de ruedas de apoyo 4, de entre las cuales al menos dos serán motorizadas 5. El hecho de colocar los accionamientos de giro o motoreductores en las ruedas, es decir, en el borde del conjunto en lugar de en el eje vertical de giro, permite reducir el tamaño de dichos motorreductores al requerir éstos menor potencia debido al gran brazo de acción.The rotation of the solar tracker with respect to the axis vertical 2 is achieved by using support wheels 4, of among which at least two will be motorized 5. The fact place the rotary drives or gearmotors on the wheels, that is, on the edge of the assembly instead of on the vertical axis of rotation, allows to reduce the size of said gearmotors by require these less power due to the large arm of action.

Asimismo, la estructura soporte 3, sirve de sustentación al eje horizontal 7 del seguidor solar, respecto al que giran los dos tableros 6. Dichos tableros se forman preferiblemente por perfilería metálica que queda soldada y atornillada. A dichos tableros 6 se fijan los paneles solares 8 que conforman los planos de paneles del seguidor y que son los responsables de la captación de los rayos solares, preferiblemente atornillados por sus marcos.Also, the support structure 3 serves as lift to the horizontal axis 7 of the solar tracker, with respect to the which rotate the two boards 6. These boards are formed preferably by metal profiles that remain welded and screwed To said panels 6 the solar panels 8 are fixed which make up the follower panel plans and which are the responsible for capturing the sun's rays, preferably screwed by their frames.

Para el movimiento de los tableros 6, y por tanto de los paneles 8, respecto al eje horizontal 7, se utilizan, por ejemplo, motorreductores de accionamiento de tornillo sinfín 9. El hecho de disponer de al menos un dispositivo de accionamiento para cada tablero permite que el movimiento de cada tablero respecto del eje horizontal, sea bien sincronizado bien independiente, en función de las necesidades de utilización.For the movement of the boards 6, and for both of the panels 8, with respect to the horizontal axis 7, are used, for example, worm drive geared motors 9.  Having at least one drive device for each board allows the movement of each board respect of the horizontal axis, be well synchronized or independent, in Function of utilization needs.

Los tableros 6 disponen asimismo de elementos de lastrado 10 para minimizar el trabajo a compresión del accionamiento, así como su pandeo.The boards 6 also have elements of ballast 10 to minimize the compressive work of the drive, as well as its buckling.
