Seguidor solar.Solar Tracker.

Sector de la técnicaTechnical sector

La presente invención está relacionada con los seguidores solares que poseen múltiples filas de módulos fotovoltaicos, proponiendo un seguidor de ese tipo con un único eje de seguimiento solar, que presenta una configuración estructural que le permite adaptarse a las características orográficas del terreno sobre el que se dispone.The present invention is related to solar trackers that have multiple rows of modules photovoltaic, proposing such a follower with a single axis solar tracking, which presents a structural configuration that allows you to adapt to the orographic characteristics of the terrain over which is available.

Estado de la técnicaState of the art

En el mercado actual existen diferentes tipos de seguidores solares, entre los que están los seguidores solares de doble eje para orientar permanentemente los paneles solares perpendiculares al sol y obtener así una máxima captación energética, y los seguidores solares de un único eje que buscan obtener una buena captación energética con un montaje más sencillo, disminuyendo los costes de fabricación, instalación y mantenimiento.In the current market there are different types of solar trackers, among which are the solar trackers of double axis to permanently orient the solar panels perpendicular to the sun and thus obtain maximum uptake energy, and single-axis solar trackers looking for obtain a good energy collection with a simpler assembly, reducing manufacturing, installation and maintenance.

Los seguidores solares de un único eje se componen generalmente de múltiples filas de placas solares que se disponen paralelas entre sí y se soportan sobre una estructura horizontal que es actuada en giro para hacer pivotar las placas solares y orientarlas hacia el sol. Las diferentes filas que componen el seguidor solar están unidas entre sí a través de unas barras de transmisión, de manera que mediante un actuador lineal se provoca el giro de una de las filas de placas solares, transmitiéndose dicho movimiento de giro al resto de filas por medio de las barras de transmisión.The single-axis solar trackers are they generally consist of multiple rows of solar panels that are they are parallel to each other and are supported on a structure horizontal that is rotated to swing the plates solar and orient them towards the sun. The different rows that make up the solar tracker are linked together through some transmission bars, so that using a linear actuator causes the rotation of one of the rows of solar panels, said turning movement being transmitted to the rest of the rows by means of of the transmission bars.

Este tipo de seguidores solares suelen presentar una estructura excesivamente rígida y por lo tanto son muy sensibles a los esfuerzos transmitidos por el viento, agravándose estos problemas de rigidez cuando aumenta el número y longitud de filas de placas solares que conforman el seguidor solar. Asimismo, la rigidez de la estructura y el excesivo espacio ocupado por este tipo de seguidores solares, dificulta su instalación cuando el terreno en donde se debe disponer presenta superficies irregulares.This type of solar trackers usually present an excessively rigid structure and therefore are very sensitive to the efforts transmitted by the wind, worsening these stiffness problems when the number and length of rows of solar panels that make up the solar tracker. Also stiffness of the structure and excessive space occupied by this type of solar trackers, makes installation difficult when the ground in where it should be arranged it presents irregular surfaces.

Por otro lado, para garantizar que el seguidor solar pueda soportar las acciones del viento y otras condiciones ambientales adversas, se suelen emplear cimentaciones de hormigón, como zapatas, o pilotes, aumentando considerablemente el coste de instalación del seguidor solar.On the other hand, to ensure that the follower solar can withstand the actions of wind and other conditions adverse environmental, concrete foundations are usually used, as shoes, or piles, greatly increasing the cost of solar tracker installation.

Se hace por tanto necesario disponer un seguidor solar con una configuración estructural que permita compensar las irregularidades del terreno y que atenúe las cargas que debe soportar la estructura debido a acciones externas.It is therefore necessary to have a follower solar with a structural configuration that allows to compensate the irregularities of the terrain and that attenuates the loads that must be support the structure due to external actions.

Objeto de la invenciónObject of the invention

De acuerdo con la presente invención se propone un seguidor solar de un único eje que presenta una configuración estructural ventajosa para poder ubicarse en terrenos que presenten superficies irregulares.In accordance with the present invention it is proposed a single axis solar tracker that has a configuration advantageous structural to be able to be located in lands that present irregular surfaces.

El seguidor solar de la invención está compuesto por múltiples filas de placas solares que incluyen varios módulos fotovoltaicos. Cada fila de placas solares va soportada por una estructura horizontal formada por un eje y unos perfiles transversales a dicho eje, siendo esta estructura horizontal susceptible de pivotar para realizar el seguimiento del sol. Para transmitir el movimiento pivotante entre filas, los ejes de las distintas filas se encuentran unidos entre sí por medio de unas barras de transmisión.The solar tracker of the invention is composed by multiple rows of solar panels that include several modules photovoltaic Each row of solar panels is supported by a horizontal structure formed by an axis and profiles transversal to said axis, this horizontal structure being susceptible to pivot to track the sun. For transmit the pivotal movement between rows, the axes of the different rows are linked together by means of transmission bars

El seguidor solar lleva directamente acoplado, en al menos un eje de una fila de placas solares, un actuador de giro que provoca el pivotado de todas las filas de placas solares. Para poder soportar las cargas a las que está sometido el actuador de giro, se ha previsto que éste se disponga sobre un poste cimentado en su parte inferior.The solar tracker has directly coupled, in at least one axis of a row of solar panels, an actuator of rotation that causes the pivoting of all rows of solar panels. In order to withstand the loads to which the actuator is subjected turning, it is planned that it be arranged on a pole cemented at the bottom.

Para poder compensar las irregularidades del terreno en donde se dispone el seguidor solar, el eje de cada fila de placas solares está divido en al menos dos semiejes que van unidos entre sí por medio de unas uniones articuladas. Preferentemente la unión se realiza mediante unas juntas cardan, aunque también es posible emplear otro tipo de uniones, como por ejemplo una rotula o elemento similar. El conjunto del seguidor solar va soportado sobre unas patas de apoyo telescópicas que van hincadas directamente al suelo y que son susceptibles de regularse en altura para igualmente poder adaptarse a la superficie del suelo.In order to compensate for the irregularities of the land where the solar tracker is arranged, the axis of each row of solar panels is divided into at least two half shafts that go joined together by means of articulated joints. Preferably the union is carried out by means of cardan joints, although it is also possible to use other types of joints, such as example a label or similar element. The follower set solar is supported on telescopic support legs that go driven directly to the ground and which are likely to be regulated in height to also be able to adapt to the surface of the ground.

Las barras de transmisión van unidas entre sí por medio de unas palancas que giran solidarias con los ejes de las filas de placas solares. Estas barras de transmisión presentan en ambos extremos unas piezas postizas que permiten regular su longitud, pudiendo así compensar la distancia existente entre las filas de placas solares, cuando existen variaciones en la superficie del suelo.The transmission bars are linked together by means of levers that turn in solidarity with the axes of the rows of solar panels. These transmission bars present in both ends some false pieces that allow you to regulate your length, thus being able to compensate for the distance between the rows of solar panels, when there are variations in the surface ground.

Los módulos fotovoltaicos de los que están compuestos las placas solares, van dispuestos sobre los perfiles transversales y se encuentran retenidos por presión a través de unas bridas que se disponen en los laterales de dichos módulos fotovoltaicos y que van unidas a los propios perfiles transversales por medio de tornillos o elementos similares.The photovoltaic modules of which they are Composed solar panels, are arranged on the profiles transverse and are retained by pressure through some flanges that are arranged on the sides of said modules photovoltaic and that are linked to the transversal profiles themselves by means of screws or similar elements.

Descripción detallada de la invenciónDetailed description of the invention

En la figura 1 se representa el seguidor solar de la invención, el cual está compuesto por varias filas (1) de placas solares (2), presentando cada placa solar (2) varios módulos fotovoltaicos (3) encargados de transformar la luz incidente del sol en energía eléctrica.Figure 1 shows the solar tracker of the invention, which is composed of several rows (1) of solar panels (2), each solar panel (2) presenting several modules photovoltaic (3) responsible for transforming the incident light of the sun in electrical energy

Los módulos fotovoltaicos (3) de cada placa solar (2) se soportan sobre una estructura horizontal formada por unos ejes (4) y unos perfiles (5) transversales a dichos ejes (4). Los ejes (4) están accionados en giro para hacer pivotar las placas solares (2) y poder realizar un seguimiento de la luz solar, tal y como se observa en la figura 2.The photovoltaic modules (3) of each board solar (2) are supported on a horizontal structure formed by axes (4) and profiles (5) transverse to said axes (4). The shafts (4) are rotated to swing the plates solar (2) and be able to track sunlight, as and as seen in figure 2.

El seguidor solar se sustenta a través de unas patas (6) de apoyo telescópicas, que van hincadas directamente en el suelo y que son capaces de variar su longitud para que el seguidor solar se pueda adaptar a terrenos con superficies irregulares. En caso de que las condiciones de resistencia del terreno así lo exijan, se ha previsto que las patas (6) de apoyo tengan en su parte inferior una cimentación, bien mediante un pilote, una zapata, u otro medio similar.The solar tracker is supported by some Telescopic support legs (6), which are directly driven into the ground and they are able to vary their length so that the follower solar can be adapted to terrains with irregular surfaces. In in case the ground resistance conditions so require, it is provided that the support legs (6) have in their part bottom one foundation, either by a pile, a shoe, or Another similar means.

En las figuras 3 y 3A se muestra en detalle la configuración de las patas (6) de apoyo telescópicas. En su parte superior cada pata (6) está formada por una abrazadera (6.1) de plástico, o similar, que rodea al eje (4) correspondiente; por la parte exterior la abrazadera (6.1) presenta una pieza de forma cilíndrica (6.1.1) y en la parte interior presenta dos semipiezas (6.1.2 y 6.1.3) que abrazan al eje (4) y giran con él, de manera que las semipiezas (6.1.2 y 6.1.3) deslizan sobre la cara interna de la pieza con forma cilíndrica (6.1.1) cuando se produce el giro del eje (4). En la parte inferior cada pata (6) presenta dos tramos rectos (6.2 y 6.3) que se desplazan verticalmente uno con respecto al otro, presentando ambos tramos rectos (6.2 y 6.3) en respectivas caras coincidentes una sucesión de agujeros (6.4), para regular la altura de la pata (6) mediante la introducción selectiva de unos bulones de apriete (no representados) por dichos agujeros (6.4). Así mediante una regulación selectiva de la altura de las patas (6) de apoyo el seguidor solar se puede adaptar a diferentes irregularidades del terreno en donde se disponga.Figures 3 and 3A show in detail the configuration of the telescopic support legs (6). In his part upper each leg (6) is formed by a clamp (6.1) of plastic, or the like, surrounding the corresponding axis (4); by outside the clamp (6.1) has a piece of shape cylindrical (6.1.1) and inside it has two half pieces (6.1.2 and 6.1.3) that hug the shaft (4) and rotate with it, so that the semi-pieces (6.1.2 and 6.1.3) slide on the inner face of the cylindrical shaped part (6.1.1) when shaft rotation occurs (4). In the lower part each leg (6) has two straight sections (6.2 and 6.3) that move vertically with respect to each other, presenting both straight sections (6.2 and 6.3) on respective faces matching a succession of holes (6.4), to adjust the height of the leg (6) by the selective introduction of some bolts tighten (not shown) by said holes (6.4). So by a selective adjustment of the height of the legs (6) of support the solar tracker can be adapted to different irregularities of the land where available.

Cada eje (4) de una misma fila (1) de placas solares (2) está divido en al menos dos semiejes (4.1, 4.2), los cuales van unidos entre sí por medio de unas uniones articuladas (7) a modo de juntas cardan, pudiendo también ser uniones con forma de rotula o cualquier otro tipo de unión que permita mantener unidos los, al menos, dos semiejes (4.1, 4.2) a la vez que permita su desalineación. Mediante la división del eje (4) en diferentes semiejes (4.1, 4.2), se pueden compensar posibles desviaciones debidas a irregularidades del terreno, profundidad de hincado de las patas (6) de apoyo, deformaciones provocados por el viento, u otras causas.Each axis (4) of the same row (1) of plates solar (2) is divided into at least two axes (4.1, 4.2), the which are linked together by means of articulated joints (7) as a cardan joint, it can also be unions shaped label or any other type of joint that allows to hold together the at least two axles (4.1, 4.2) while allowing its misalignment By dividing the shaft (4) into different half shafts (4.1, 4.2), possible deviations can be compensated due to irregularities of the terrain, depth of driving support legs (6), deformations caused by wind, or other Causes.

Como se puede observar en detalle en la figura 4, el accionamiento en giro de los ejes (4), para realizar el seguimiento solar, se lleva a cabo mediante un actuador de giro (8) que va acoplado directamente sobre el propio eje (4), yendo montado dicho actuador de giro (8) sobre un poste (9) que posee una cimentación (9.1) en su base para compensar la gran carga que debe soportar el actuador de giro (8) cuando se lleva a cabo el pivotado de las placas solares (2).As can be seen in detail in the figure 4, the rotation drive of the shafts (4), to perform the solar tracking, is carried out by means of a turn actuator (8) which is coupled directly on the shaft itself (4), being mounted said rotation actuator (8) on a post (9) having a foundation (9.1) at its base to compensate for the large load that must be support the rotary actuator (8) when pivoting is carried out of solar panels (2).

Se ha previsto que únicamente una de las filas (1) de placas solares (2) presente el actuador de giro (8), mientras que el giro del resto de filas (1) se lleva a cabo mediante unas barras de transmisión (10) que conectan las filas (1) entre sí. En caso de que el seguidor solar presente un gran número de filas (1) se pueden disponer más filas (1) motorizadas intercaladas entre las filas (1) que no poseen actuador de giro (8). La figura 4 muestra una fila (1) motorizada mediante un actuador de giro (8) y la figura 5 muestra una fila (1) que no está motorizada.It is planned that only one of the rows (1) of solar panels (2) present the rotation actuator (8), while that the rotation of the rest of the rows (1) is carried out by means of transmission bars (10) that connect the rows (1) to each other. In If the solar tracker has a large number of rows (1) more motorized rows (1) can be arranged sandwiched between the rows (1) that do not have a turn actuator (8). Figure 4 shows a row (1) motorized by means of a rotation actuator (8) and the figure 5 shows a row (1) that is not motorized.

Las barras de transmisión (10) van unidas entre sí a través de unas palancas (12) que giran solidarias con los ejes (4). Por otro lado las barras de transmisión (10) presentan en ambos extremos unas piezas postizas (11) que permiten regular su longitud y poder así compensar la distancia entre las filas (1) cuando existen irregularidades en el terreno, para lo cual tanto las barras de transmisión (10) como las piezas postizas (11) tiene practicados una serie de agujeros a distancias predefinidas a través de los cuales se hace pasar un tornillo, o bulón, para unir ambos elementos. Por otro lado, cada palanca (12) presenta dos articulaciones de giro (12.1 y 12.2), las cuales asocian dos piezas postizas (11) consecutivas y por lo tanto dos barras de transmisión (10) consecutivas, permitiendo la basculación del conjunto.The transmission bars (10) are joined between yes through levers (12) that turn in solidarity with the axes (4). On the other hand the transmission bars (10) present in both ends some false pieces (11) that allow to regulate its length and thus be able to compensate for the distance between the rows (1) when there are irregularities in the terrain, for which both the bars of transmission (10) as the false pieces (11) have practiced a series of holes at predefined distances through the which is passed a screw, or bolt, to join both elements. On the other hand, each lever (12) has two turning joints (12.1 and 12.2), which associate two pieces consecutive false (11) and therefore two transmission bars (10) consecutive, allowing the whole to swing.

Como se observa en detalle en las figuras 6, 6A y 6B, los módulos fotovoltaicos (3) de las placas solares (2) apoyan sobre los perfiles transversales (5), yendo los perfiles transversales (5) unidos al eje (4) por medio de unos abarcones metálicos (13) (ver esquema figura 6A). Por otra parte, los módulos fotovoltaicos (3) son retenidos contra los perfiles transversales (5) por medio de unas bridas (14), las cuales se disponen en los laterales de los módulos fotovoltaicos (3) y se sujetan a los perfiles transversales (5) por medio de tornillos (15), (ver esquema figura 6B), de modo que al apretar los tornillos (15) respectivos, dichas bridas (14) sujetan por presión a los módulos fotovoltaicos (3) contra los perfiles transversales (5); sujetando las bridas (14) que se encuentran en el centro de las placas solares (2) a dos módulos fotovoltaicos (3) consecutivos, mientras que las placas (14) que se encuentran en los extremos de las placas solares (2) solo sujetan a un módulo fotovoltaico (3).As seen in detail in Figures 6, 6A and 6B, the photovoltaic modules (3) of the solar panels (2) support on the cross sections (5), the profiles going cross-sections (5) attached to the axis (4) by means of rods metallic (13) (see diagram figure 6A). On the other hand, the modules photovoltaic (3) are retained against cross sections (5) by means of flanges (14), which are arranged in the sides of the photovoltaic modules (3) and are attached to the cross sections (5) by means of screws (15), (see diagram figure 6B), so that when tightening the respective screws (15), said flanges (14) pressurize the photovoltaic modules (3) against the cross profiles (5); holding the flanges (14) which are located in the center of the solar panels (2) to two consecutive photovoltaic modules (3), while the plates (14) found at the ends of solar panels (2) only subject to a photovoltaic module (3).
