Description

Seguidor solar monoposte.Monoposte solar tracker.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un seguidor solar monoposte, del tipo que montan una pluralidad de placas solares o fotovoltáicas, y que está dotado de dos ejes de giro tal que se puede variar su orientación azimutal y su inclinación para posicionar en todo momento los paneles perpendiculares a los rayos del sol, al objeto de conseguir un óptimo al rendimiento.The present invention relates to a follower monoposte solar, of the type that mount a plurality of plates solar or photovoltaic, and that is equipped with two axes of rotation such that you can vary your azimuthal orientation and inclination to position the panels perpendicular to the rays at all times of the sun, in order to achieve optimum performance.

Antecedentes de la invenciónBackground of the invention

Se conocen diferentes soluciones para seguidores solares monoposte.Different solutions for followers are known  monoposte solar.

Por ejemplo el modelo utilidad 9901296, referente a un seguidor de dos ejes para placas solares, comprende un único poste sobre el que se fija una estructura susceptible de montar placas fotovoltáicas, y que presenta dos ejes de giro que se mueven mediante sendos motorreductores, y que controlan de forma independiente la rotación e inclinación de dicha estructura, y por tanto el ángulo azimutal y la inclinación de los paneles montados en la misma; estando controlados estos movimientos por un microprocesador, y cooperando unos sensores en su posicionamiento inicial, y desde éste efectuando la búsqueda posicional del sol el programa de control.For example utility model 9901296, referring to a two-axis tracker for solar panels, it includes a single post on which a structure susceptible to assemble photovoltaic plates, and that presents two axes of rotation that are they move by means of two gearmotors, and that they control in a way independent rotation and inclination of said structure, and by both azimuthal angle and inclination of mounted panels in the same; these movements being controlled by a microprocessor, and cooperating sensors in its positioning initial, and from this one making the positional search of the sun the control program

En este mismo sentido va dirigido el modelo de utilidad 200402608, con la única diferencia de que el sensor consiste en una cápsula de vidrio dividida en tres partes por un tabique en forma de T de caras brillantes, en cada un de cuyas partes se coloca un sensor, todo ello para determinar la posición del sol y orientar el panel, habiéndose previsto igualmente la colocación de un anemómetro para autoprotección de los paneles frente al viento colocandolos en una posición de protección en caso de vientos fuertes.In this same direction the model of utility 200402608, with the only difference that the sensor it consists of a glass capsule divided into three parts by a T-shaped partition of bright faces, in each of whose parts a sensor is placed, all to determine the position of the sun and orient the panel, with the placement of an anemometer for panel self-protection against the wind placing them in a protective position in case  of strong winds.

En este último sentido se dirigen también las anteriores CN 1525117 y TW567298B, que describen la inclusión en un sistema seguidor solar de un anemómetro que detecta condiciones inadecuadas del viento para posicionar los paneles en una posición inicial.In the latter sense, the previous CN 1525117 and TW567298B, which describe the inclusion in a solar tracker system of an anemometer that detects conditions inadequate wind to position the panels in a position initial.

Estos dos registros ejecutan la regulación de la inclinación mediante un motorreductor, lo cual acarrea problemas de precisión posicional debido a las torsiones de la estructura superior por efecto del viento y de las dilataciones, mayores a mayor superficie de los paneles, y que deben ser compensadas en un único punto de apoyo a través del cual el motorreductor trasmite el movimiento de inclinación. Además no disponen de medios de fijación de la posición azimutal, con lo que los golpes de viento se transmiten directamente al motorreductor de giro azimutal ocasionando muchas roturas del mismo.These two registers execute the regulation of the  tilt by a gearmotor, which causes problems positional precision due to structure twists superior due to the effect of wind and dilatation, greater than greater surface area of the panels, and that must be compensated in a only support point through which the gearmotor transmits the tilt movement They also do not have fixing means  of the azimuthal position, so that the wind blows transmitted directly to the azimuthal gearmotor causing many breaks of it.

Con el fin de evitar estos inconvenientes, también se conoce el modelo utilidad 200500413, en el cual se divide la superficie total abarcada por los paneles en varios grupos de menor superficie, cada uno de los cuales montado en su propio poste orientable, y habiéndose previsto una transmisión que sincroniza movimiento de todos ellos tanto en orientación azimutal como en inclinación. Sin embargo ocupa una superficie mayor con todos los reenvíos y trasmisiones que sincronizan el movimiento de los paneles, aparte de su mayor coste.In order to avoid these inconveniences, utility model 200500413 is also known, in which divide the total area covered by the panels into several smaller surface groups, each of which mounted on its own adjustable pole, and having planned a transmission that synchronizes movement of all of them both in azimuthal orientation As in inclination. However, it occupies a larger area with all forwardings and transmissions that synchronize the movement of the panels, apart from their higher cost.

Por último también se conoce el modelo utilidad 200400947, que protege un poste especialmente concebido para la sustentación de un seguidor solar, el cual comprende una convencional estructura de hormigón armado con cuatro armaduras verticales con sus correspondientes estribos de unión embebidos en una masa de hormigón, lo cual genera un poste macizo inviable para alojar en su interior instalaciones auxiliares, como por ejemplo los sistemas electrónicos del seguidor solar.Finally, the utility model is also known 200400947, which protects a pole specially designed for lift of a solar tracker, which comprises a Conventional reinforced concrete structure with four reinforcements vertical with their corresponding joining stirrups embedded in a concrete mass, which generates an unviable solid pole for host auxiliary facilities inside, such as the electronic systems of the solar tracker.
