FORMA PREFERENTE DE REALlZACION PREFERRED FORM OF REALIZATION
A continuación se describirá un ejemplo de realización de la invención atendiendo a las figuras anteriormente descritas. La invención, principalmente se basa en la utilización de al menos un, y preferiblemente ocho, elementos en espiral, bimetálicos, «5a al 5h) que van confinados en un tubo absorbedor térmico o cuerpo negro (7) y unidos o sujetos por un extremo a un eje (1) y por el otro extremo unidos o sujetos al tubo absorbedor (7), que forma un conjunto con un tubo transparente (2). Dichos elementos en espiral bimetálicos (5a al 5h) son calentados por la radiación solar concentrada en dicho tubo absorbedor mediante una superficie reflectante que ocupa la mitad interior del lado cóncavo del tubo transparente (2), que puede ser un espejo concentrador (4) o una imprimación reflectante. An exemplary embodiment of the invention will be described below in accordance with the figures described above. The invention is mainly based on the use of at least one, and preferably eight, spiral elements, bimetallic, «5a to 5h) which are confined in a thermal absorber tube or black body (7) and joined or held by one end to an axis (1) and at the other end joined or attached to the absorber tube (7), which forms a set with a transparent tube (2). Said bimetallic spiral elements (5a to 5h) are heated by solar radiation concentrated in said absorber tube by means of a reflective surface that occupies the inner half of the concave side of the transparent tube (2), which can be a concentrating mirror (4) or a reflective primer.
Dicho eje es capaz de reproducir un efecto giratorio cuando los elementos en espiral (5a al 5h) bimetálicos se deforman por la dilatación debido al calor que el espejo (4) concentra en el tubo absorbedor (7) en forma de radiación solar,. Said axis is capable of reproducing a rotating effect when the bimetallic spiral elements (5a to 5h) are deformed by dilation due to the heat that the mirror (4) concentrates on the absorber tube (7) in the form of solar radiation.
El sistema está formado por dos partes principales, la primera el eje (1) alojado en los cojinetes (6a, 6b) y el conjunto formado por el tubo transparente (2), espejo (4), tubo absorbedor (7) y los cuales forman un todo sin parte móvil alguna entre los elementos que lo conforman, en adelante cuerpo principal. El eje va sujeto al extremo de menor diámetro de los elementos espirales bimetálicos (5a a 5h), y estos a su vez van sujetos en su otro extremo o extremo de más diámetro al tubo absorbedor (7), estando dichos elementos espirales (5a al 5h) confinados dentro del tubo absorbedor (7) para evitar que la dilatación de los mismos provoque el aumento de diámetro de estos, obligándolos así a estirarse longitudinalmente para reproducir el movimiento de rotación del eje (1). El funcionamiento del motor solar comienza cuando la radiación solar incide en el espejo concentrador o superficie reflectante (4) a través del tubo transparente (2), siendo dicha radiaCión concentrada en el tubo absorbedor (7) y aumentando la temperatura de este, en cuyo interior van alojados los elementos espirales bimetálicos (5a al 5h). Estos elementos espirales (5a al 5h) son calentados y comienzan a estirarse debido a la dilatación haciendo girar el eje (1) sobre los cojinetes (6a,6b), y produciendo así el movimiento giratorio de los piñones (3a,3b), o por el contrario si el eje (1) está f~o se consigue un movimiento del resto del cuerpo principal. The system is formed by two main parts, the first one the shaft (1) housed in the bearings (6a, 6b) and the assembly formed by the transparent tube (2), mirror (4), absorber tube (7) and which they form a whole without any moving part between the elements that comprise it, henceforth the main body. The axis is attached to the end of smaller diameter of the bimetallic spiral elements (5a to 5h), and these in turn are attached at its other end or end of greater diameter to the absorber tube (7), said spiral elements (5a to 5h) confined within the absorber tube (7) to prevent their expansion causing the diameter increase, thus forcing them to stretch longitudinally to reproduce the rotational movement of the shaft (1). The operation of the solar motor begins when the solar radiation strikes the concentrating mirror or reflective surface (4) through the transparent tube (2), said radiation being concentrated in the absorber tube (7) and increasing its temperature, in which Inside the bimetallic spiral elements are housed (5a to 5h). These spiral elements (5a to 5h) are heated and begin to stretch due to the expansion by rotating the shaft (1) on the bearings (6a, 6b), and thus producing the rotating movement of the pinions (3a, 3b), or on the contrary, if the axis (1) is cold, a movement of the rest of the main body is achieved.
Para usar el motor solar como seguidor solar, el eje ha de permanecer inmóvil permitiendo así el movimiento del resto del cuerpo principal, el cual forma a efectos de dicho movimiento un todo, y para lo cual el motor solar objeto de la invención se orienta To use the solar motor as a solar tracker, the axis must remain motionless thus allowing the movement of the rest of the main body, which forms a whole for the purpose of said movement, and for which the solar motor object of the invention is oriented
con el lado cóncavo del espejo (4) apuntando en dirección Este con una inclinación de 30°. Cuando el sol asoma en el horizonte, la radiación incide en el espejo (4) el cual concentra la luz en el tubo absorbedor (1), calentando este paulatinamente e iniciando lentamente el giro del cuerpo principal en dirección contraria, saliendo a los 5° de giro de la zona de radiación pues el espejo actúa también de barrera lumínica al ser opaco por su lado convexo (lo que se denominará zona de sombra). Lo anterior se produce porque el giro del motor debido a que la dilatación de los elementos espirales bimetálicos (5a al 5h) es más rápida que el avance del sol por la bóveda celeste, razón por la que el espejo (4) ha de ir en una posición de avance respecto de la perpendicular de incidencia de la radiación solar, y de ahí que el ángulo de partida o ángulo de orientación inicial de la concavidad del espejo (4) respecto del terreno sea de 30°. Una vez alcanzada la zona de sombra, se inicia el enfriamiento paulatino del tubo absorbedor (7) por lo que los elementos espirales bimetálicos (5a al 5h) empiezan a contraerse provocando el movimiento de giro contrario del cuerpo principal en busca del Sol. Lo anterior se repite sucesivamente durante el día por lo que la orientación continua al astro viene dada por el ciclo luz/sombra que el espejo concentrador provoca sobre el tubo absorbedor (1). De esta manera, mediante pequeñas oscilaciones desde el amanecer hasta el ocaso el motor se mantiene orientado y por ende cualquier espejo o panel acoplado al mismo, volviendo este a su posición de reposo original cuando la intensidad lumínica no es suficiente durante el ocaso. Para solucionar el movimiento del motor durante alternancia de nubosidad se propone que el seguidor solar esté formado por dos motores solares, de tal forma que ambos giren de manera solidaria pero que el desfase entre ambos en su orientación sea de 30°, consiguiendo con ello que el seguidor solar no pierda la orientación debido a la interferencia intermitente o momentánea de una nube, de tal forma que el motor solar desfasado recoja el testigo y continúe con el movimiento de orientación supliendo la función del motor solar principal. Por otro lado, el giro del eje está limitado a un ángulo máximo que obedece al límite de dilatación de los elementos espirales bimetálicos (5a al 5h) y a la longitud de los mismos, pudiendo desmultiplicar su desarrollo para obtener más par o multiplicar este para alcanzar más velocidad. El giro del eje (1) así como el par de torsión y la velocidad angular del mismo es proporcional a la temperatura en el tubo absorbedor (7), al compuesto bimetálico utilizado en los elementos bimetálicos (5a al 5h), al número de bimetales ensamblados al mismo así como al tamaño del concentrador. with the concave side of the mirror (4) pointing eastward with an inclination of 30 °. When the sun rises on the horizon, the radiation hits the mirror (4) which concentrates the light in the absorber tube (1), gradually heating it and slowly starting the rotation of the main body in the opposite direction, leaving at 5 ° rotation of the radiation zone because the mirror also acts as a light barrier by being opaque on its convex side (what will be called the shadow zone). The above occurs because the rotation of the motor because the dilation of the bimetallic spiral elements (5a to 5h) is faster than the advance of the sun through the celestial vault, which is why the mirror (4) has to go in a position of advance with respect to the perpendicular incidence of solar radiation, and hence the starting angle or initial orientation angle of the concavity of the mirror (4) with respect to the ground is 30 °. Once the shadow zone is reached, the gradual cooling of the absorber tube (7) begins, so that the bimetallic spiral elements (5a to 5h) begin to contract causing the opposite turning movement of the main body in search of the Sun. The above it is repeated successively during the day so that the continuous orientation to the star is given by the light / shadow cycle that the concentrating mirror causes on the absorber tube (1). In this way, by small oscillations from sunrise to sunset the engine remains oriented and therefore any mirror or panel coupled to it, returning this to its original resting position when the light intensity is not sufficient during sunset. To solve the movement of the engine during alternation of cloudiness, it is proposed that the solar tracker be formed by two solar motors, so that both rotate in a solidary manner but that the gap between them in their orientation is 30 °, thereby achieving that the solar tracker does not lose its orientation due to the intermittent or momentary interference of a cloud, so that the outdated solar motor picks up the warning light and continues with the orientation movement supplying the function of the main solar motor. On the other hand, the rotation of the axis is limited to a maximum angle that is due to the dilation limit of the bimetallic spiral elements (5a to 5h) and the length thereof, being able to multiply their development to obtain more torque or multiply this to reach more speed. The rotation of the shaft (1) as well as the torque and angular velocity thereof is proportional to the temperature in the absorber tube (7), to the bimetallic compound used in the bimetallic elements (5a to 5h), to the number of bimetals assembled to it as well as to the size of the hub.
De esta manera podemos usar un solo motor solar para efectuar el movimiento EsteOeste en un solo eje, o combinar dos de ellos uno holizontal y otro vertical para lograr que se produzca el movimiento a dos ejes, disponiendo para ello un bastidor acorde a las necesidades específicas. In this way we can use a single solar motor to perform the East-East movement on a single axis, or combine two of them one holizontal and one vertical to achieve that the two-axis movement occurs, providing for this a frame according to the specific needs .
