DESCRIPCIÓN DESCRIPTION
Heliostato para concentración solar en torre de captación. Heliostat for solar concentration in collection tower.
Sector de la técnica 5 Technical sector 5
La invención de la máquina heliostato se enmarca en el sector de las energías renovables, concretamente en los de concentración solar o (CSP Concentrated Solar Power), donde es necesario que el heliostato sea capaz de posicionar la dirección normal de los elementos que sustentan, en éste caso espejos, hacia cualquier dirección de un semi-hemisferio, es decir los 10 elementos que sustenta el heliostato deben ser posicionados en determinados ángulos acimutales y de elevación. Para ello es necesario que el heliostato sea capaz de posicionar la normal de su superficie normal en un determinado ángulo acimutal y otro de elevación. The invention of the heliostat machine is part of the renewable energy sector, specifically those of solar concentration or (CSP Concentrated Solar Power), where it is necessary that the heliostat be able to position the normal direction of the elements that support it, in this case mirrors, towards any direction of a semi-hemisphere, that is, the 10 elements that support the heliostat must be positioned at certain azimuthal and elevation angles. For this, it is necessary that the heliostat be able to position the normal of its normal surface at a certain azimuth and elevation angle.
El heliostato puede ser usado igualmente para sustento de paneles solares fotovoltaicos. 15 The heliostat can also be used to support photovoltaic solar panels. fifteen
Estado de la técnica State of the art
Los heliostatos conocidos generan los mecanismos de movimiento dobles necesarios mencionados, acimutal y de elevación, empleando generalmente un único elemento mecánico, 20 instalado en la parte central del heliostato, siendo éstos por lo general mecanismos muy robustos y complejos, que deben soportar grandes cargas estructurales, originadas por su propio peso e inclemencias meteorológicas, como viento o nieve. Known heliostats generate the necessary double movement mechanisms mentioned, azimuthal and lifting, generally using a single mechanical element, 20 installed in the central part of the heliostat, these being generally very robust and complex mechanisms, which must withstand large structural loads , originated by its own weight and weather, such as wind or snow.
Explicación de la invención 25 Explanation of the invention
El sistema a patentar consiste en una máquina heliostato tal como se observa en las figuras 1, 2 y 3, dicho heliostato soportará un conjunto de espejos, con la finalidad de reflejar los rayos solares incidentes sobre una superficie receptora menor, y por tanto conseguir una radiación solar concentrada sobre ésta. Para conseguir esta finalidad emplea los mecanismos 30 denominados de 'elevación´ y 'lateral', cuyos elementos y disposición se muestran en las figuras 4 y 5 respectivamente. The system to be patented consists of a heliostat machine as seen in figures 1, 2 and 3, said heliostat will support a set of mirrors, in order to reflect the incident sun rays on a smaller receiving surface, and therefore achieve a solar radiation concentrated on it. To achieve this purpose, it uses the so-called 'elevation' and 'lateral' mechanisms 30, whose elements and arrangement are shown in Figures 4 and 5 respectively.
En el primer movimiento, de elevación, la máquina es capaz de posicionarse a una determinada inclinación global, con respecto a su eje longitudinal, como se aprecia en la 35 figura 2, dirección sur-norte, con respecto a la instalación prevista. Para ello el heliostato utiliza el mecanismo mostrado en la figura 4, dicho mecanismo impulsa en dirección aproximadamente vertical a la barra transversal anterior (1) lo que hace que todo el conjunto del marco-soporte del heliostato pivote sobre unos elementos (19), situados en la parte superior de los pilares traseros (7) y fijados a la barra transversal posterior (2), 40 proporcionándole el mecanismo de giro indicado, ver figuras 1 y 2. Con dicho movimiento de inclinación el heliostato consigue que los espejos que soportan posicionen su dirección normal a un determinado ángulo de elevación, y conseguir uno de los dos movimientos necesarios. In the first lifting movement, the machine is able to position itself at a certain global inclination, with respect to its longitudinal axis, as shown in Figure 2, south-north direction, with respect to the planned installation. For this, the heliostat uses the mechanism shown in Figure 4, said mechanism drives the front transverse bar (1) approximately vertically, which makes the entire heliostat support frame assembly pivot on elements (19), located at the top of the rear pillars (7) and fixed to the rear crossbar (2), 40 providing the indicated rotation mechanism, see figures 1 and 2. With this tilt movement the heliostat ensures that the mirrors that support position its normal direction at a certain elevation angle, and get one of the two necessary movements.
En el segundo movimiento, lateral, le permite sólo al conjunto de los espejos a un determinado 45 ángulo con respecto al eje transversal de la máquina heliostato, y conseguir el segundo de los movimientos necesario. Para ello se emplea el mecanismo mostrado en la figura 5. Dicho mecanismo, ubicado sobre unos brazos (3), figura 1, actuaría sobre la barra de transmisión lateral (3) que a su vez, a través de pletinas (7) se unen a las barras de soporte de espejos (4) que accionarían a éstas de una manera circular, y centradas en todo momento por la barra 50 transversal anterior (1) y la barra transversal posterior (2). Las barras de soporte de espejos (4) que soportan al conjunto de los espejos, en su movimiento circular, producen un movimiento igualmente circular en los espejos de manera simultánea, haciendo que toda la radiación incidente sea vea reflejada en la misma medida. In the second, lateral movement, it allows only the set of mirrors at a certain angle with respect to the transverse axis of the heliostat machine, and to achieve the second of the necessary movements. For this, the mechanism shown in Figure 5 is used. Said mechanism, located on some arms (3), Figure 1, would act on the lateral transmission bar (3) which, in turn, are connected through plates (7). to the support bars of mirrors (4) that would drive them in a circular manner, and centered at all times by the anterior transverse bar 50 (1) and the posterior transverse bar (2). The support bars of mirrors (4) that support the set of mirrors, in their circular motion, produce an equally circular movement in the mirrors simultaneously, making all the incident radiation to be reflected in the same measure.
Ambos movimientos permiten que la normal de los espejos se posicione en un determinado ángulo de elevación y acimut y por tanto conseguir que los rayos solares incidentes se reflejen hacia el punto deseado, punto superior de la torre de captación de la radiación solar. Both movements allow the normal of the mirrors to be positioned at a certain elevation and azimuth angle and therefore achieve that the incident solar rays are reflected towards the desired point, the upper point of the solar radiation collection tower.
Breve descripción de los dibujos 5 Brief description of the drawings 5
La figuras 1 y 3 muestran la máquina desde su parte frontal y trasera respectivamente. Figures 1 and 3 show the machine from its front and back respectively.
La figura (2) muestra la máquina desde una vista lateral, donde se observa a ésta en una determinada elevación global. 10 Figure (2) shows the machine from a side view, where it is observed at a certain global elevation. 10
En la figura (4) se observan los elementos necesarios para el movimiento de elevación que le da al heliostato una inclinación global como se aprecia en la figura 2, y consta de una palanca (10), un actuador (12), un montante (11) y los elementos de articulación (13). Éste conjunto se sustenta sobre pilar delantero (8) de la máquina heliostato y actúa sobre la barra transversal 15 anterior (1), que hace pivotar toda la máquina sobre los dos ejes situados en los pilares traseros (7). Figure (4) shows the elements necessary for the lifting movement that gives the heliostat a global inclination as seen in Figure 2, and consists of a lever (10), an actuator (12), an upright ( 11) and the articulation elements (13). This assembly is supported on the front pillar (8) of the heliostat machine and acts on the anterior crossbar 15 (1), which pivots the entire machine on the two axes located on the rear pillars (7).
En la figura 5, se observa los elementos para el movimiento lateral de los espejos, formado por una palanca (15), impulsada por el actuador (17) que se fija y articula en la parte fija (16). La 20 palanca actúa sobre la barra de transmisión lateral (5), que a su vez mueven las platinas (18) que hacen girar las barras de soporte de los espejos (6) que sustentan al conjunto de espejos. In figure 5, the elements for the lateral movement of the mirrors are observed, formed by a lever (15), driven by the actuator (17) that is fixed and articulated in the fixed part (16). The lever acts on the lateral transmission bar (5), which in turn moves the plates (18) that rotate the support bars of the mirrors (6) that support the set of mirrors.
