SEGUIDOR FOTOVOLTAICOPHOTOVOLTAIC TRACKER

Sector técnico:Technical sector:

Estructuras articuladas soporte de paneles fotovoltaicos, para plantas de producción de energía eléctrica, que permiten el seguimiento solar.Articulated support structures for photovoltaic panels, for electricity production plants, which allow solar monitoring.

Estado de la técnica:State of the art:

Las plantas de producción eléctrica a través de paneles fotovoltaicos, suponen un elemento crucial dentro del ámbito de las energías renovables.Electricity production plants through photovoltaic panels are a crucial element in the field of renewable energies.

Estas plantas, se pueden catalogar dependiendo de diferentes criterios.These plants can be classified depending on different criteria.

Un criterio es la tipología de las estructuras que se instalan como soporte de los paneles fotovoltaicos. Atendiendo a este criterio, existen dos tipos fundamentales de estructuras soporte de los paneles fotovoltaicos: fijas o articuladas.One criterion is the type of structures that are installed to support the photovoltaic panels. Based on this criterion, there are two fundamental types of support structures for photovoltaic panels: fixed or articulated.

Las estructuras articuladas permiten la instalación de un sistema motor que varíe la inclinación de los paneles fotovoltaicos en función de las diferentes posiciones relativas del sol en el firmamento.The articulated structures allow the installation of a motor system that varies the inclination of the photovoltaic panels depending on the different relative positions of the sun in the sky.

Las estructuras articuladas, comúnmente en el sector conocidas como "seguidores" han recorrido un camino de evolución técnica buscando la optimización económica.Articulated structures, commonly known in the sector as "trackers" have traveled a path of technical evolution seeking economic optimization.

En un principio existían seguidores articulados de dos ejes y de un eje, pero, los de dos ejes, debido a sucoste tanto de instalación como de mantenimiento, 25 años, actualmente están en desuso.At first, there were articulated trackers with two axes and one axle, but the two-axle trackers, due to the cost of both installation and maintenance, 25 years, are currently in disuse.

Los seguidores que actualmente más se instalan en la construcción de Plantas Fotovoltaicas son los seguidores a un eje.The trackers that are currently most installed in the construction of Photovoltaic Plants are one-axis trackers.

Existen diferentes diseños de estructuras articuladas (seguidores) a 1 eje, en función de la disposición de los paneles en planta, es decir:There are different designs of articulated structures (trackers) to 1 axis, depending on the layout of the panels on the ground, that is:

3H.- quiere decir que la estructura articulada soporta una geometría basada en 3 paneles fotovoltaicos con sus lados largos adyacentes y paralelos al eje de giro.3H.- means that the articulated structure supports a geometry based on 3 photovoltaic panels with their long sides adjacent and parallel to the axis of rotation.

2V.- quiere decir que la estructura articulada soporta una geometría basada en 2 paneles fotovoltaicos con sus lados cortos adyacentes yparalelos al eje de giro.2V.- means that the articulated structure supports a geometry based on 2 photovoltaic panels with their short sides adjacent and parallel to the axis of rotation.

1V.- quiere decir que la estructura articulada soporta una geometría basada en 1 panel fotovoltaico con su lado largo perpendicular al eje de giro.1V.- means that the articulated structure supports a geometry based on 1 photovoltaic panel with its long side perpendicular to the axis of rotation.

1V bifila .- Están constituidos por dos filas 1V, cada una con un eje. Ambos ejes son paralelos entre sí y están unidos mediante una articulación para compartir elemento tractor, de modo que se produzca un ahorro de componentes. 1V bifila .- They are made up of two rows 1V, each with an axis. Both axes are parallel to each other and are linked by means of a joint to share the tractor element, thereby saving components.

Cada estructura, de un tipo o de otro, de un fabricante o de otro, en función de sus cálculos y componentes tiene sus características intrínsecasEach structure, of one type or another, from one manufacturer or another, depending on its calculations and components, has its intrinsic characteristics.

La evolución de la técnica ha continuado, y en particular nuestro modelo de utilidad se refiere a los Seguidores a un eje "1V bifila".The evolution of the technique has continued, and in particular our utility model refers to the Followers to a "1V bifila" axis.

Descripción en detalle de la invención:Detailed description of the invention:

Los seguidores de dos filas paralelas a un eje, se comportan mal frente a vientos fuertes, técnicamente hablando son estructuras muy esbeltas que pueden presentar fenómenos de aeroelasticidad cercanos a la resonancia.The followers of two rows parallel to an axis, behave badly against strong winds, technically speaking they are very slender structures that can present phenomena of aeroelasticity close to resonance.

Además, presentan otro inconveniente, desde nuestro punto de vista, y es que la conexión por un único punto entre las dos filas concentra tensiones en ambos extremos de la articulación, generando desequilibrios en el reparto de los esfuerzos que, se acrecientan con el hecho del paso del tiempo acelerando el deterioro.In addition, they present another drawback, from our point of view, and that is that the connection at a single point between the two rows concentrates tensions at both ends of the joint, generating imbalances in the distribution of efforts that increase with the fact of the passage of time accelerating deterioration.

Nuestra invención, consigue reducir la esbeltez de la estructura y distribuir la transmisión de esfuerzos entre las filas al conectar las filas por más de una articulación, como se puede ver en la figura 1.Our invention manages to reduce the slenderness of the structure and distribute the transmission of efforts between the rows by connecting the rows by more than one joint, as can be seen in figure 1.

En el ejemplo aportado transmitimos en tres puntos, utilizando tres bielas articuladas, diseñadas de acuerdo a figura 2. Las distribuimos de modo que estén situadas cerca de los pilares y, a su vez, de manera que queden soportando tras de longitud similar.In the example provided, we transmit at three points, using three articulated connecting rods, designed according to figure 2. We distribute them so that they are located near the pillars and, in turn, so that they remain supporting behind of similar length.

La transmisión por tres puntos consigue:The three-point transmission achieves:

• que los esfuerzos máximos puntuales en cada una de las bielas se reduzcaun 50% (la reducción teórica sería un 66%, pero establecemos 50% del lado de la seguridad. • That the maximum specific efforts in each of the connecting rods are reduced by 50% (the theoretical reduction would be 66%, but we establish 50% on the safety side.

• al aumentar el número de bielas de transmisión, conseguimos tres puntos de transmisión del bloqueo motor de la fila motora a la fila remolque, con lo que la Inercia a Torsión se multiplica por 3, reduciendo los problemas causados por vientos fuertes y extremos a partir de 14 m/s.• By increasing the number of transmission connecting rods, we achieve three transmission points of the motor lock from the motor row to the trailer row, with which the Torsional Inertia is multiplied by 3, reducing the problems caused by strong and extreme winds from of 14 m / s.

Exposición de un modo de realización de la invención:Presentation of an embodiment of the invention:

Un modo de realizar la invención es mediante la instalación de más de una biela de acuerdo a lo indicado en Figura 3. Cada biela se constituye con 2 piezas metálicas que abrazan al eje y una articulación vía perno con un tubo horizontal. En figura 2, por ejemplo, están instaladas 3 bielas. One way of carrying out the invention is by installing more than one connecting rod according to what is indicated in Figure 3. Each connecting rod is made up of 2 metal pieces that embrace the shaft and a joint via bolt with a horizontal tube. In figure 2, for example, 3 connecting rods are installed.

Aplicación industrial.Industrial application.

Esta invención presenta una alta aplicabilidad industrial, puesto que en los próximos años se desarrollarán numerosos proyectos fotovoltaicos que requerirán una mayor resistencia frente a los fenómenos causados por el viento.This invention has a high industrial applicability, since in the coming years numerous photovoltaic projects will be developed that will require greater resistance to phenomena caused by the wind.

También es reseñable que consideramos como otro factor que favorecerá la aplicabilidad industrial, la ventaja en el mantenimiento. El repartir los esfuerzos a lo largo del seguidor en vez de concentrarlos en únicamente dos puntos, hace que, durante la vida útil de estos proyectos (que es de 25 años) el número de problemas estructurales estimado sea inferior a los seguidores del mismo tipo.It is also noteworthy that we consider as another factor that will favor industrial applicability, the advantage in maintenance. Spreading the efforts along the tracker instead of concentrating them on just two points means that, during the useful life of these projects (which is 25 years), the number of estimated structural problems is lower than the tracker of the same type.
