Description

TREN DE LAVADO DE PLACAS TERMO SOLARES. La presente invención se refiere a un tren de lavado de los cristales que componen cualquier tipo de instalación termo-solar aportando la novedad de garantizar la integridad de la instalación no 5 dañándola con rozaduras, colisiones, tropiezos o invasiones del vehículo portador del dispositivo de limpieza y en ocasiones del tanque remolque, mediante lo siguiente: En lugar de efectuar la limpieza desde un vehículo, ésta se realiza desde un carro portador del sistema de boquillas de riego que discurre por un carril guía o rail, encontrándose el depósito de agua 10 en un extremo del raíl y siendo recogida o extendida la manguera de agua por un carrete. Esta novedad pone fin a los numerosos accidentes que se producen en las instalaciones termo solares provocados por los vehículos de limpieza, además de suponer un notable ahorro de agua y personal frente a los antiguos métodos de limpieza a mano mediante manguera. 15 Tiene su campo de aplicación en la industria de la energía termo solar y particularmente en la industria auxiliar de la limpieza de placas termo solares. Puesto que las instalaciones termo solares están ubicadas al aire libre, son sensibles a la recepción de polvo y otras sustancias que 20 disminuyen el rendimiento de la instalación. Por lo tanto, es necesario realizar limpiezas periódicas de las superficies reflectoras para mantener el rendimiento de la instalación en unas condiciones satisfactorias. Es por ello por lo que la presente invención pretende aumentar la eficacia en la captación de la luz solar y consiguiente rendimiento de un campo de placas termo-solares dispuestas en hileras, mecanizando racionalmente la fase de limpieza, haciéndola más estable, fácil, segura y 5 por supuesto ahorrar sus costes a largo plazo, desarrollando una actividad de limpieza automática, mecánica y controlada mediante un programa informático acoplable al sistema de control del campo termo solar. Pretende también controlar de una forma eficaz y práctica este 10 sistema de limpieza invirtiendo el menor tiempo posible, utilizando sólo los recursos necesarios, alcanzando la mejor optimización en la limpieza del campo termo-solar, en la utilización de recursos, bajando los costes económicos y aumentando la eficacia del sistema de limpieza. Pero además de todo lo expuesto, que sin duda también lo consiguen en mayor 15 o menor medida las invenciones conocidas referidas a la limpieza de estas placas, la principal ventaja de esta invención reside la ausencia de riesgos de accidentes y consiguiente seguridad para la instalación termo solar que esta invención plantea. En este sector de la técnica priman aquellos desarrollos efectivos 20 Y específicamente dedicados a la función en cuestión, que den lugar a un sistema de sencilla instalación, con bajo coste y resultados técnicamente apreciables. Las características del sistema propuesto en esta invención se adaptan perfectamente a este concepto, ofreciendo al estado de la técnica una realización novedosa, simple, sencilla y de fabricación y ejecución económica. Se conocen en el estado de la técnica sistemas que realizan la misma función que esta invención, la limpieza de placas termo solares, 5 pero ninguno con las características diferenciales y ventajas de esta invención, como se verá a continuación. Así el documento ES 2 345 082 A 1 se refiere a un dispositivo de limpieza para paneles fotovoltaicos, pudiendo también servir para limpiar paneles termo solares, para su instalación en un medio de arrastre, en 10 concreto en un vehículo tractor o similar, estructurado en base a un brazo articulado posicionable a voluntad sobre los módulos fotovoltaicos de una instalación generadora de energía eléctrica de este tipo, o sobre los paneles termo solares de una instalación térmica, dotado en su extremo libre de una barra de proyección equipada con una multiplicidad de 15 boquillas de salida de líquido pulverizado de limpieza para su proyección sobre la superficie de los módulos, siendo la barra susceptible de adoptar inclinaciones variables dentro de una gama predeterminada de valores angulares, con el fin de adaptarse tanto a las inclinaciones de los módulos fotovoltaicos y paneles termo solares de las instalaciones fijas, como a las 20 inclinaciones variables de los módulos que equipan los seguidores. Puesto que estas instalaciones fotovoltaicas o termo solares se encuentran en la mayoría de los casos sobre terreno rústico, se diferencia esta invención de la aquí propuesta en que el vehículo tractor o similar en .. el que se instala se enfrenta frecuentemente a situaciones en las que la tierra mojada bien por el agua de limpieza o bien por la lluvia caída se transforma en barro dificultando maniobrar el vehículo entre las hileras de las instalaciones o en las vueltas para enfilar la siguiente hilera. Otro 5 inconveniente es que la cercanía de los instalaciones entre sí o la estrechez de los caminos entre hileras o los obstáculos para el vehículo que a veces presentan las ramificaciones de las estructuras que soportan las instalaciones dificulta al vehículo tractor y al tanque de agua la entrada o el sorteo de obstáculos o el cambio de dirección, por lo que a veces se 10 producen accidentes, rozamientos, roturas de consecuencias costosas y desagradables. Con la presente invención se evitan por completo los accidentes debidos a las maniobras del vehículo, ya que el vehículo es sustituido por un carro que discurre sobre raíl resultando una tarea segura y libre de accidentes y roturas. 15 ES 2 316 317 A1 se refiere a un método para la limpieza de espejos con sección parabólica de una planta termo solar formada en una o más hileras, por el que se desplaza a lo largo de la longitud de cada hilera de espejos un aparato o vehículo portador de los medios de limpieza, provisto de forma unida o separada de un tanque de agua limpia 20 que proyecta agua a presión y cepilla la superficie de los espejos. Al igual que el anterior este método, al disponer de un aparato o vehículo al que va unido o separado un tanque de agua limpia, se enfrenta a los mismos inconvenientes, al ser el terreno irregular el vehículo y en su caso el tanque remolque pueden rozar o tropezar o invadir los elementos de la instalación termo solar provocando pequeños, medianos o importantes daños, circunstancia ésta que es imposible que se de con la presente invención en la que no existe ni vehrculo portador de medios de limpieza 5 ni tanque portador de agua y por consiguientes es inexistente el riesgo de accidente. Igualmente el documento ES 1 070 268 U se refiere a una máquina limpiadora de placas solares, del tipo que se acopla mediante un bastidor a un vehículo autopropulsado con los inconvenientes ya citados. 10 También los documentos ES 1069495 U Y ES 2350083 A1 se refieren a vehículos para la limpieza de colectores solares. En consecuencia no se ha encontrado en el estado de la técnica ningún sistema de limpieza de instalaciones termo solares que presenten la ventaja de que su uso no dañe en absoluto la instalación objeto de 15 limpieza garantizando así su integridad. Pero otra ventaja fundamental de este sistema es que su funcionamiento, al ser programable mediante circuito electrónico, no precisa la intervención de ningún operario, reduciendo por consiguiente considerablemente sus costes de explotación. 20 La presente invención se constituye a partir de una estructura tubular exenta e individual, apoyada sobre los pilotes de hormigón de la estructura termo solar mediante medios de fijación mecánicos de tal manera que dicha estructura tubular recorre la hilera de espejos termo --------------------------- solares por la parte inferior de su frente de un extremo a otro. Sobre dicha estructura tubular se halla sujeto mediante medios de unión apropiados un raíl que sirve de guía para el desplazamiento de un carro provisto de ruedas de acero inoxidable, portador de un tubo colector de agua provisto 5 de boquillas de riego, el cual sale de la cabeza del carro y adopta la forma curvilínea del espejo termo solar para acercar las boquillas a la mejor distancia de proyección del agua. Ventajosamente es posible el máximo acercamiento gracias a que la estructura del tren de lavado objeto de invención es fija. 10 Dos motores se encuentran uno a cada extremo del raíl guía. El de la derecha desenrolla y enrolla en carrete un cable de acero que es enrollado y desenrollado por el de la izquierda según el carro se desplace a un lado o a otro por el raíl. Un tercer motor enrolla y desenrolla la manguera que conecta el depósito de agua y bomba de presión al carro 15 según éste se desplace a la izquierda o retorne a la derecha. El depósito de agua se encuentra ubicado en uno de los extremos de la vía y contiene agua desmineralizada y tratada para no dejar huellas de suciedad en los cristales termo solares. Un circuito electrónico programable permite que la puesta en 20 marcha y parado del sistema de limpieza se realice en los intervalos de tiempo programados, de tal manera que ventajosamente no es necesaria la intervención de ningún operario para su funcionamiento, lo que repercute muy favorablemente en la rentabilidad de este sistema frente a los conocidos en el estado de la técnica. Para una mejor comprensión de esta memoria descriptiva se acompañan unos dibujos que a modo de ejemplo no limitativo describen 5 una realización preferida de la invención: Figura 1.-Hilera de placas termo solares En dichas figuras se aprecian los siguientes elementos numerados: 1.-Estructura tubular exenta 10 2.-Pilotes 3.-Estructura de hilera termo solar 4.-Medios de fijación 5.-Hilera de espejos termo solares 6.-Raíl guía 15 7.-Carro 8.-Ruedas del carro de acero inoxidable 9.-Tubo colector de agua de forma curvilínea 10.-Boquillas de aspersión 11.-Cabeza del carro 20 12.-Motor de la derecha 13.-Carrete de manguera 14.-Depósito de agua 15.-Bomba de presión de agua 16.-Motor de la izquierda 17.-Cable de acero 18.-Carrete de cable.

El depósito de agua (14) se encuentra ubicado en el extremo derecho de la vía (6). WASHING TRAIN OF SOLAR THERMO PLATES. The present invention relates to a washing train of the crystals that make up any type of thermo-solar installation, providing the novelty of guaranteeing the integrity of the installation not damaging it with chafing, collisions, trips or invasions of the carrier vehicle of the cleaning device. and sometimes the towing tank, by means of the following: Instead of cleaning from a vehicle, it is carried out from a carriage carrying the irrigation nozzle system that runs along a guide rail or rail, the water tank 10 being in one end of the rail and the water hose being picked up or extended by a spool. This novelty puts an end to the numerous accidents that occur in thermo-solar installations caused by cleaning vehicles, in addition to supposing a notable saving of water and personnel in comparison with the old methods of hand-cleaning by hose. 15 It has its field of application in the solar thermal energy industry and particularly in the auxiliary industry of the cleaning of solar thermal plates. Since the solar thermal installations are located outdoors, they are sensitive to the reception of dust and other substances that diminish the performance of the installation. Therefore, it is necessary to perform periodic cleaning of the reflecting surfaces to maintain the performance of the installation in satisfactory conditions. That is why the present invention aims to increase the efficiency in the capture of sunlight and consequent performance of a field of thermo-solar plates arranged in rows, rationally mechanizing the cleaning phase, making it more stable, easy, safe and 5 of course, save your costs in the long term, developing an automatic, mechanical and controlled cleaning activity through a computer program that can be coupled to the control system of the solar thermal field. It also aims to control in an effective and practical way this cleaning system by investing the least possible time, using only the necessary resources, achieving the best optimization in the cleaning of the thermo-solar field, in the use of resources, lowering the economic costs and increasing the effectiveness of the cleaning system. But in addition to all the above, which undoubtedly also achieved in greater or lesser extent the known inventions related to the cleaning of these plates, the main advantage of this invention lies in the absence of accident risks and consequent safety for the thermo installation solar that this invention raises. In this sector of the art, those effective developments that are specifically dedicated to the function in question, that give rise to a system of simple installation, with low cost and technically appreciable results, prevail. The characteristics of the system proposed in this invention are perfectly adapted to this concept, offering the state of the technique a novel, simple, simple and manufacturing execution and economic execution. Systems known to be in the state of the art that perform the same function as this invention, the cleaning of thermo solar plates, but none with the differential characteristics and advantages of this invention, as will be seen below. Thus, document ES 2 345 082 A 1 refers to a cleaning device for photovoltaic panels, which can also serve to clean solar thermal panels, for installation in a traction means, in concrete in a tractor vehicle or the like, structured in base to an articulated arm freely positionable on the photovoltaic modules of a power generating facility of this type, or on the solar thermal panels of a thermal installation, endowed at its free end with a projection bar equipped with a multiplicity of 15 cleaning spray nozzles for spraying onto the surface of the modules, the bar being able to adopt variable inclinations within a predetermined range of angular values, in order to adapt both to the inclinations of the photovoltaic modules and panels solar thermos of fixed installations, as at 20 variable inclinations of modules s that equip the followers. Since these photovoltaic or solar thermal installations are in most cases on rustic land, this invention differs from the one proposed here in that the tractor vehicle or similar in .. the one who settles frequently faces situations in which the soil wetted by the cleaning water or by the falling rain turns into mud making it difficult to maneuver the vehicle between the rows of the facilities or in the laps to take the next row . Another disadvantage is that the proximity of the facilities to each other or the narrowness of the roads between rows or the obstacles for the vehicle that sometimes have the ramifications of the structures that support the facilities make it difficult for the tractor vehicle and the water tank to enter or the draw of obstacles or the change of direction, so that sometimes accidents, friction, breakages of costly and unpleasant consequences occur. With the present invention, accidents due to maneuvers of the vehicle are completely avoided, since the vehicle is replaced by a car that runs on a rail resulting in a safe and accident-free and break-free task. 15 2 316 317 A1 relates to a method for cleaning mirrors with a parabolic section of a thermo-solar plant formed in one or more rows, by which an apparatus or apparatus is moved along the length of each row of mirrors. carrier vehicle of the cleaning means, provided in a united or separate form of a tank of clean water 20 that projects pressurized water and brushes the surface of the mirrors. Like the previous one, this method, having an apparatus or vehicle to which a tank of clean water is attached or separated, faces the same inconveniences, since the terrain is irregular, the vehicle and in its case the trailer tank can rub or trip or invade the elements of the solar thermal installation causing small, medium or significant damage, a circumstance that is impossible to be with the present invention in which there is no vehicle carrier cleaning means 5 or tank carrier of water and consequently there is no risk of accident. Likewise, document ES 1 070 268 U refers to a solar panel cleaning machine, of the type that is coupled by a frame to a self-propelled vehicle with the aforementioned drawbacks. 10 Also documents ES 1069495 U and ES 2350083 A1 refer to vehicles for cleaning solar collectors. Consequently, no system for cleaning solar thermal installations has been found in the state of the art, which have the advantage that their use does not damage the cleaned installation at all, thus guaranteeing its integrity. But another fundamental advantage of this system is that its operation, being programmable by electronic circuit, does not require the intervention of any operator, thus considerably reducing its operating costs. The present invention is constituted from an exempt and individual tubular structure, supported on the concrete piles of the thermo solar structure by means of mechanical fixation in such a way that said tubular structure runs through the row of thermo-mirrors ----- ---------------------- solar panels on the lower part of your forehead from one end to the other. On said tubular structure is attached by means of appropriate joining a rail that serves as a guide for the movement of a carriage provided with stainless steel wheels, carrier of a water collection pipe provided with irrigation nozzles, which leaves the head of the car and adopts the curvilinear shape of the thermo solar mirror to bring the nozzles closer to the best water projection distance. Advantageously, the closest approach is possible because the structure of the washing train object of the invention is fixed. 10 Two engines are located at each end of the guide rail. The one on the right unrolls and rolls a steel cable that is rolled and unrolled by the one on the left as the car moves to one side or the other on the rail. A third motor winds and unrolls the hose connecting the water tank and the pressure pump to the carriage 15 as it moves to the left or returns to the right. The water tank is located at one end of the road and contains demineralized water and treated to avoid traces of dirt in the solar thermal crystals. A programmable electronic circuit allows the start and stop of the cleaning system to be carried out in the programmed time intervals, in such a way that it is advantageously not necessary for any operator to operate, which it has a very favorable effect on the profitability of this system compared to those known in the state of the art. For a better understanding of this specification, some drawings are attached which, by way of non-limiting example, describe a preferred embodiment of the invention: Figure 1.-Row of solar thermal plates. In said figures the following numbered elements are shown: 1.- Free-standing tubular structure 10 2.-Piles 3.-Thermo solar windrow structure 4.-Fixing means 5.-Row of thermo-solar mirrors 6.-Guide rail 15 7.-Trolley 8.-Stainless steel trolley wheels 9 .-Curvilinear water collection tube 10.-Spray nozzles 11.-Truck head 20 12.-Right motor 13.-Hose reel 14.-Water tank 15.-Water pressure pump 16.-Motor left 17.-Cable steel 18.-Cable reel. A preferred embodiment of the proposed invention is formed from the following elements: An exempt (1) and individual tubular structure, supported on the piles (2) of the thermo solar structure (3) by means of mechanical fixing means (4) in such a way that said tubular structure (1) runs through the row of thermo-solar mirrors (5) through the lower part of its front from one end to the other.
