Description

Seguidor solar.Solar Tracker.

Objeto de la invenciónObject of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un seguidor solar, y más concretamente a los medios de seguimiento que actúan sobre el colector de un seguidor solar para conseguir la correspondiente orientación o seguimiento desde la salida hasta la ocultación del sol.The present invention, as expressed in the set forth in this specification, refers to a follower solar, and more specifically to the monitoring means that act on the collector of a solar tracker to get the corresponding orientation or follow-up from departure to hiding from the sun

El objeto de la invención es lograr un seguidor solar cuya actuación de seguimiento queda asegurada aún a falta de suministro eléctrico, siendo aplicable en todos los seguidores solares basados en dos cilindros para el seguimiento solar propiamente dicho.The object of the invention is to achieve a follower site whose follow-up action is assured even in the absence of electricity supply, being applicable in all followers solar based on two cylinders for solar tracking Properly said.

Antecedentes de la invenciónBackground of the invention

Actualmente, los colectores solares parabólicos o de cualquier otro tipo suelen emplear para el seguimiento solar un sistema de doble cilindro, es decir formado por dos cilindros hidráulicos de doble acción montados en sendas palancas al correspondiente eje de rotación del colector, de manera que un controlador evalúa las señales de un codificador de rotación, conmutando dos entradas de control independientes de los dos cilindros.Currently, parabolic solar collectors or of any other type usually used for solar tracking a double cylinder system, that is to say formed by two cylinders double action hydraulics mounted on individual levers corresponding axis of rotation of the collector, so that a controller evaluates the signals of a rotation encoder, switching two control inputs independent of the two cylinders

Es decir, mediante la actuación continuada de los cilindros que forman el sistema de seguimiento, el colector realiza el seguimiento total desde la salida del sol hasta la ocultación, al objeto de conseguir el máximo aprovechamiento de los rayos solares para que incidan perpendicularmente sobre los paneles solares, y obtener con ello el máximo rendimiento de la instalación.That is, through the continued performance of the cylinders that make up the tracking system, the collector performs full tracking from sunrise to concealment, in order to get the most out of solar rays so that they impact perpendicularly on the panels solar, and thereby obtain the maximum performance of the installation.

Pues bien, la función de los dispositivos de seguimiento no es otra que la de capturar el máximo de radiación posible para su transformación en energía eléctrica, siendo por lo tanto habitual dotar estos sistemas de medios electrónicos para determinar en todo momento su posicionamiento. El inconveniente que presenta este tipo de sistemas es que al utilizar medios electrónicos, éstos deben estar constantemente conectados a una fuente de energía eléctrica, por lo que en caso de producirse cortes o averías en el fluido eléctrico suministrador, evidentemente el sistema no cumple su función, habiendo que instalar acumuladores eléctricos (baterías, SAI, etc).Well, the function of the devices of tracking is none other than capturing the maximum radiation possible for its transformation into electrical energy, being therefore both usual to equip these electronic media systems to determine your positioning at all times. The inconvenience that presents this type of systems is that when using media electronic, these must be constantly connected to a source of electrical energy, so if it occurs cuts or breakdowns in the electrical supply fluid, obviously the system does not fulfill its function, having to install electric accumulators (batteries, UPS, etc.).

Descripción de la invenciónDescription of the invention

El seguidor solar objeto de la invención está previsto para que incluso en condiciones de absoluta falta de suministro eléctrico sea capaz de transmitir la situación del doble sistema de cilindros, tanto para situaciones de emergencia como para el normal funcionamiento del seguidor.The solar tracker object of the invention is planned so that even in conditions of absolute lack of power supply be able to convey the situation of double cylinder system, both for emergency situations and for the normal operation of the follower.

Concretamente, se trata de un sencillo dispositivo hidráulico que determina la entrada y salida del fluido de cada cilindro para lograr la extensión o contracción del vástago, según convenga.Specifically, it is a simple hydraulic device that determines the entry and exit of the fluid of each cylinder to achieve extension or contraction of the stem, as appropriate.

Ese dispositivo funciona como consecuencia de la incorporación de una leva o elemento similar que va montado sobre el propio eje de giro del colector, leva que actúa sobre un mando o interruptor hidráulico que comanda cada uno de los cilindros, determinando el sentido de circulación y por lo tanto el sentido de movimiento o desplazamiento de los vástagos de los cilindros para efectuar el seguimiento solar que se pretende.That device works as a result of the  incorporation of a cam or similar element that is mounted on the collector's own axis of rotation, a cam that acts on a control or hydraulic switch that controls each of the cylinders, determining the direction of circulation and therefore the sense of movement or displacement of the cylinder rods for carry out the solar tracking that is intended.

Breve descripción de los dibujosBrief description of the drawings

Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva de una hoja única de planos en la que se ha representado de forma esquemática el sistema de seguimiento solar basado en la leva incorporada como elemento fundamental de la invención, en combinación con un interruptor hidráulico.To complement the description that then it will be done and in order to help a better understanding of the features of the invention, accompanies the present descriptive report of a single sheet of plans in which the monitoring system has been schematically represented solar based on the built-in cam as a fundamental element of the invention, in combination with a hydraulic switch.

Descripción de la forma de realización preferidaDescription of the preferred embodiment

A la vista de la comentada figura, puede observarse cómo el seguidor solar de la invención es del tipo de los que incluyen un sistema de seguimiento basado en dos cilindros hidráulicos 1 y 2 con sus correspondientes vástagos 1' y 2', estando éstos articulados a una pieza común y de configuración triangular 3 como se representa en la figura.In view of the commented figure, you can observe how the solar tracker of the invention is of the type of those that include a two-cylinder based tracking system Hydraulics 1 and 2 with their corresponding stems 1 'and 2', being these articulated to a common and configuration piece triangular 3 as depicted in the figure.

Pues bien, la novedad de la invención consiste en incorporar una leva 4 para cada cilindro o elemento similar montada sobre el propio eje de giro 5 del colector solar 6, de modo que cuando se produce el giro de esa leva 4 y en virtud de los escalonamientos 7 de la misma, se producirá la incidencia sobre los mandos mecánicos 8, de manera que en virtud de que éste comanda cada uno de los distribuidores correspondientes a los cilindros hidráulicos 1 y 2, se establecerá el sentido de circulación del aceite y por lo tanto el desplazamiento en un sentido u otro de los vástagos 1' y 2' de esos cilindros 1 y 2, variando el sentido de giro y por lo tanto variando la posición del
colector 6.Well, the novelty of the invention consists in incorporating a cam 4 for each cylinder or similar element mounted on the axis of rotation 5 of the solar collector 6, so that when the rotation of that cam 4 occurs and by virtue of the staggering 7 thereof, the incidence will occur on the mechanical controls 8, so that by virtue of the latter commanding each of the distributors corresponding to the hydraulic cylinders 1 and 2, the direction of oil circulation will be established and therefore both the displacement in one direction or another of the rods 1 'and 2' of those cylinders 1 and 2, varying the direction of rotation and therefore varying the position of the
collector 6.
