Campo de aplicación de la invenciónField of application of the invention

El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la industria dedicada a la fabricación de dispositivos y sistemas de limpieza para paneles solares.The field of application of the present invention It is part of the technical sector of the industry dedicated to the manufacture of cleaning devices and systems for panels solar.

Antecedentes de la invenciónBackground of the invention

En la actualidad, y como referencia al estado de la técnica, debe señalarse que se conocen diferentes sistemas y dispositivos para llevar a cabo la limpieza de los paneles solares, estando dichos los dispositivos, en la mayor parís de los casos, previstos para su acoplamiento a un vehículo tractor y basándose el dispositivo de limpieza en un rodillo o cepillo cilíndrico vinculado articuladamente a un brazo telescópico que a su vez está articulado a otro brazo que se proyecta desde el propio vehículo tractor, complementándose con un cilindro hidráulico entre los dos brazos telescópicos para llevar a cabo una inclinación en mayor o menor medida del brazo telescópico al que está vinculado el cepillo o cilindro de limpieza.Currently, and as a reference to the state of the technique, it should be noted that different systems are known and devices for cleaning solar panels, the devices being said, in most of the cases, provided for coupling to a tractor vehicle and based on cleaning device on a linked roller or cylindrical brush articulated to a telescopic arm which in turn is articulated to another arm that projects from the tractor vehicle itself, complementing with a hydraulic cylinder between the two arms telescopic to perform a tilt in greater or lesser measure of the telescopic arm to which the brush is attached or cleaning cylinder

Dichos dispositivos, sin embargo, presentan a menudo el inconveniente de que la aproximación al panel solar correspondiente del cepillo o elemento limpiador se realiza de acuerdo con la visión del operador, es decir del conductor de vehículo tractor, lo que a veces supone una aproximación que sobrepasa el limite, y en otros casos no alcanza el propio panel solar, en el primer caso con el consiguiente riesgo de deterioro y/o rallado de los propios paneles, y en el segundo por una limpieza ineficaz.Such devices, however, present often the inconvenience that the approach to the solar panel Corresponding brush or cleaning element is made of according to the vision of the operator, that is to say of the driver of tractor vehicle, which sometimes involves an approach that exceeds the limit, and in other cases does not reach the panel itself solar, in the first case with the consequent risk of deterioration and / or grated the panels themselves, and in the second one for a cleaning ineffective.

A esos problemas hay que añadir el hecho de que, en aquellas ocasiones en que es necesario desplazar el vehículo tractor para llevar a cabo la limpieza total de un panel de grandes dimensiones, la irregularidad del terreno supone un serio inconveniente, puesto que, aún en el caso de que el dispositivo disponga de brazos articulados o incluso de sensores de aproximación, estos no son capaces de controlar el movimiento del vehículo y el cambio de inclinación del conjunto, haciendo que la tarea de limpieza sea ineficaz o mucho más lenta debido a que deberá ser el propio operario quien corrija la posición de cepillo en cada desplazamiento del vehículo.To these problems must be added the fact that, on those occasions when it is necessary to move the vehicle tractor to carry out the total cleaning of a large panel dimensions, the irregularity of the terrain is a serious inconvenient, since, even if the device have articulated arms or even sensors approach, these are not able to control the movement of the vehicle and the inclination change of the set, making the cleaning task is ineffective or much slower because it should be the operator himself who corrects the brush position in each vehicle displacement

Por otra parte, la limpieza de los paneles que realiza la mayoría de dispositivos existentes, consiste simplemente en una limpieza a base de agua y jabón u otros líquidos, pero que no incluye el secado posterior de la superficie del panel. Ello hace que, al evaporarse el agua, queden restos de cal y/o de jabón u otras sustancias que empañan el panel y, por tanto, siguen impidiendo su rendimiento óptimo, con lo que el trabajo de limpieza realizado sobre los paneles resulta poco eficaz.Moreover, the cleaning of the panels that performs most existing devices, it simply consists in a cleaning based on soap and water or other liquids, but not includes subsequent drying of the panel surface. He does that, when the water evaporates, remains of lime and / or soap remain other substances that tarnish the panel and therefore continue impeding its optimal performance, thereby cleaning work done on the panels is inefficient.

El objetivo de la presente invención es, pues, desarrollar un nuevo vehículo de limpieza con rodillo para paneles solares que evite los inconvenientes anteriormente descritos y permita conseguir una mayor eficacia de trabajo, debiendo señalarse que el propio solicitante es titular de sendos Modelos de Utilidad 20080185 y 200930096 en los que se describen dispositivos de limpieza del tipo que aquí concierne y en los que, sí bien se alcanzan niveles satisfactorios de eficacia en la limpieza de los paneles solares, no se resuelven adecuadamente los citados inconvenientes de irregularidades en el terreno y de secado del
panel.The objective of the present invention is, therefore, to develop a new roller cleaning vehicle for solar panels that avoids the aforementioned drawbacks and allows to achieve greater work efficiency, it should be noted that the applicant himself is the owner of two Utility Models 20080185 and 200930096 in which cleaning devices of the type concerned are described and in which, although satisfactory levels of efficiency in the cleaning of solar panels are achieved, the said inconveniences of irregularities in the terrain and of drying of
panel.

Así mismo, el peticionario desconoce la existencia de ningún otro vehículo de limpieza con rodillo para paneles solares o invención de aplicación similar que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta el que aquí se preconiza, estando los detalles caracterizadores del mismo convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva.Likewise, the petitioner is unaware of the existence of any other roller cleaning vehicle for solar panels or similar application invention that has some technical, structural and constitutive characteristics similar to those presented by the one here recommended, the details being characterizers thereof conveniently collected in the Final claims that accompany this report descriptive
