Abstract
The invention relates to a system based on a hydraulically operated kinematic rod-crank mechanism including a tower (1). According to the invention, the tower terminates downward in a moving ring (2) which rotates in relation to a stationary ring (5) by means of four hydraulic pistons (6) in order to produce an azimuth movement and said tower terminates upward in a shaft (3) parallel to the ring (2), on which shaft a sail (4), bearing solar collectors and actuated by two hydraulic pistons (7), can pivot in order to produce a zenith movement. The aforementioned components form a mechanically sturdy structure which requires little maintenance and allows extremely slow movements in the absence of complex reduction gear mechanisms and excessive inertial force.

La invención se sitúa pues en el ámbito de los mecanismos para captación de Ia radiación solar.The invention thus falls within the scope of the mechanisms for capturing solar radiation.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, el rendimiento de un captador de energía solar, como por ejemplo de un panel fotovoltaico, es función de Ia dirección con Ia que Ia radiación solar
alcanza la superficie operativa de dicho captador, y Ia radiación solar es de dirección permanentemente cambiante, tanto en sentido acimutal como cenital.As is known, the performance of a solar energy collector, such as a photovoltaic panel, is a function of the direction with which the solar radiation it reaches the operating surface of said collector, and the solar radiation is permanently changing direction, both azimuthal and zenithal.
Estro trae consigo que los captadores solares estén dotados de dos movimientos según los planos cenital y acimutal anteriormente citados, en orden a optimizar el rendimiento de los mismos, utilizándose para ello diferentes tipos de mecanismos motrices con los que se consigue esta movilidad combinada.This brings with it that solar collectors are equipped with two movements according to the aforementioned zenith and azimuth planes, in order to optimize their performance, using different types of driving mechanisms with which this combined mobility is achieved.
Las diferentes soluciones adoptadas se diferencian básicamente en aspectos constructivos y de diseño, tales como Ia mecánica del sistema de seguimiento adoptado, en unos casos hidráulico, en otros con tornillos de potencia, o con sistema de tornillos sinfín, mediante motores eléctricos con moto-reductores, etc.The different solutions adopted basically differ in construction and design aspects, such as the mechanics of the monitoring system adopted, in some cases hydraulic, in others with power screws, or with screw system, by electric motors with moto-reducers , etc.
Sin embargo todos ellos presentan como denominador común el adoptar soluciones mecánicas complejas en las que el mantenimiento y/o Ia reparación del equipo, en caso de avería, puede resultar un problema, siendo preciso en algunos casos llegar al desmontaje completo del seguidor.However, all of them have as common denominator the adoption of complex mechanical solutions in which the maintenance and / or repair of the equipment, in case of failure, can be a problem, being necessary in some cases to reach the complete disassembly of the follower.
Especial mención merece el problema inherente a Ia velocidad de movimiento, que en algunos casos hace necesario recurrir a complejos sistemas reductores, caros y con mantenimiento también costoso.Special mention deserves the problem inherent in the speed of movement, which in some cases makes it necessary to resort to complex reducing systems, expensive and also expensive maintenance.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El sistema propuesto resuelve de manera plenamente satisfactoria Ia problemática anteriormente expuesta, consiguiendo una máxima simplicidad mecánica, con fácil instalación y transporte, mecánicamente robusto y optimizado según sus condiciones de funcionamiento, con un costo de fabricación bajo y un
mantenimiento igualmente bajo.The proposed system solves in a fully satisfactory manner the above-mentioned problem, achieving maximum mechanical simplicity, with easy installation and transport, mechanically robust and optimized according to its operating conditions, with a low manufacturing cost and a equally low maintenance.
Para ello y de forma más concreta dicho sistema, con seguimiento solar de dos ejes basado en mecanismos cinemáticos biela-manivela con accionamiento hidráulico, permite el giro del captador solar en los planos acimutal y cenital, situándose en todo momento en posición perpendicular a Ia dirección de los rayos solares, estando estructurado mediante un componente consistente en un mecanismo cinemático para conseguir el movimiento combinado sobre los dos ejes citados, y una estructura de celosía obtenida mediante Ia combinación de una torre y una vela, unidas entre sí articuladamente y concebida para soportar tanto el peso de los captadores solares como Ia acción del viento sobre los mismos.For this, and more specifically, said system, with two-axis solar tracking based on crank-crank kinematic mechanisms with hydraulic actuation, allows the rotation of the solar collector in the azimuthal and zenith planes, being at all times perpendicular to the direction of the solar rays, being structured by a component consisting of a kinematic mechanism to achieve the combined movement on the two aforementioned axes, and a lattice structure obtained by means of the combination of a tower and a candle, joined together articulated and designed to withstand both the weight of the solar collectors and the action of the wind on them.
El sistema de accionamiento es hidráulico, como anteriormente se ha dicho, consistente en seis pistones hidráulicos agrupados en dos grupos, uno de cuatro unidades para el movimiento acimutal, es decir para el giro de Ia torre con respecto al suelo, y otro de dos para el movimiento cenital, es decir para Ia basculación de Ia vela con respecto a dicha torre, de manera que este sistema hidráulico permite conseguir una velocidad de giro adecuada para el seguimiento sin ser necesario intercalar motores reductores de velocidad.The drive system is hydraulic, as previously stated, consisting of six hydraulic pistons grouped in two groups, one of four units for azimuthal movement, that is, for the rotation of the tower with respect to the ground, and another of two for the zenith movement, that is to say for the tilting of the sail with respect to said tower, so that this hydraulic system allows to achieve an adequate turning speed for the follow-up without the need to insert speed reducing motors.
Finalmente y de acuerdo con otra de las características de Ia invención se ha previsto que el equipo hidráulico cuente con acumuladores o depósitos de presión que permiten al sistema trabajar eventualmente de forma autónoma, ante una ausencia de energía eléctrica para poner Ia vela horizontal por motivos de seguridad ante viento y un posible fallo eléctrico.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A Ia vista de las figuras reseñadas puede observarse como en el sistema de seguimiento que Ia invención propone participa una torre (1), con una estructura de celosía como se observa especialmente en Ia figura 1 , en Ia que se define un anillo
inferior (2) y un eje transversal y superior (3) paralelo al plano de dicho anillo (2) y destinado a constituir el eje de basculación para una vela (4), de estructura reticular, Ia mostrada a su vez en Ia figura 2, y destinada a soportar a las placas fotovoltaicas o captadores de energía solar de que se trate, no representados en los dibujos.In view of the aforementioned figures, it can be observed that in the monitoring system that the invention proposes, a tower (1) participates, with a lattice structure, as observed especially in Figure 1, in which a ring is defined lower (2) and a transverse and upper axis (3) parallel to the plane of said ring (2) and intended to constitute the tilt axis for a sail (4), of reticular structure, shown in turn in Figure 2 , and intended to support the photovoltaic panels or solar energy collectors in question, not represented in the drawings.
El citado anillo (2) está montado con posibilidad de giro sobre otro anillo fijo a Ia cimentación del conjunto. El giro del anillo móvil respecto del fijo se lleva a cabo mediante una serie de ruedas intercaladas entre los dos anillos, haciendo Ia función de rodamiento axial. El movimiento de giro de un anillo respecto de otro se realiza mediante un sistema hidráulico constituido por cuatro pistones (6) articulados en sus dos extremos conectados dos a dos y convenientemente comandados para cada instante del día. La configuración de cuatro pistones permite que el sistema esté compensado mecánicamente Io que permite minimizar los empujes radiales, haciendo posible un sistema mecánicamente más compacto, simple, optimizado, robusto que los actualmente existentes en el mercado.Said ring (2) is mounted with the possibility of turning on another fixed ring to the foundation of the assembly. The rotation of the movable ring with respect to the fixed one is carried out by means of a series of wheels interspersed between the two rings, making the function of axial bearing. The rotation movement of one ring with respect to another is carried out by means of a hydraulic system consisting of four pistons (6) articulated at its two ends connected two by two and conveniently controlled for each moment of the day. The four-piston configuration allows the system to be mechanically compensated, which minimizes radial thrusts, making a mechanically more compact, simple, optimized, robust system possible than those currently available on the market.
Complementariamente a las zonas extremas y superiores de Ia torre (1) se asocian, de forma articulada al igual que los pistones hidráulicos (6), sendos pistones hidráulicos (7), tal como muestra Ia figura 4, de manera que cada uno de estos dos pistones extremos (7) configuran con Ia torre (1) y con Ia vela (4) un triángulo deformable que hace que a medida que varía Ia longitud efectiva de dichos pistones hidráulicos (7), varíe el ángulo de inclinación de Ia vela (4), según el movimiento cenital previsto para los captadores de energía solar.In addition to the extreme and upper areas of the tower (1) they are associated, in an articulated manner, as well as the hydraulic pistons (6), two hydraulic pistons (7), as shown in Figure 4, so that each of these two extreme pistons (7) configure with the tower (1) and with the sail (4) a deformable triangle that makes as the effective length of said hydraulic pistons (7) varies, the angle of inclination of the sail varies ( 4), according to the zenith movement planned for solar energy collectors.
Tanto los cuatro pistones hidráulicos inferiores (6), como los dos superiores (7) están relacionados a través de una central hidráulica, con alimentación eléctrica, y a expensas de una electrónica de control.Both the four lower hydraulic pistons (6) and the upper two (7) are related through a hydraulic power plant, with power supply, and at the expense of a control electronics.
Tal como anteriormente se ha dicho con dicha central hidráulica colaborará un
acumulador o depósito de presión, tampoco representado en las figuras, que permite al sistema trabajar eventualmente de forma autónoma en ausencia de energía eléctrica. El sistema de acumulación permite mandar presión a los cilindros que hacen girar de Ia vela, permitiendo que estos se extiendan aún cuando Ia central hidráulica deje de funcionar debido de un fallo eléctrico. El resultado es que Ia vela se sitúa en una posición de seguridad (horizontal paralela al suelo) hasta que Ia alimentación eléctrica a Ia central hidráulica se restituya.
As previously stated with said hydraulic power plant, a pressure accumulator or reservoir, also not shown in the figures, which allows the system to work autonomously if there is no electric power. The accumulation system allows pressure to be sent to the cylinders that rotate the sail, allowing them to extend even when the hydraulic power plant stops working due to an electrical failure. The result is that the sail is placed in a safety position (horizontal parallel to the ground) until the power supply to the hydraulic power plant is restored.
