Description

DESCRIPCIÓN DESCRIPTION
DISPOSITIVO AUTOLIM PIANTE PARA RIEGO SELF-CLEANING DEVICE FOR IRRIGATION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención, tal como se indica en el título, se refiere a un dispositivo concebido para el sector del regadío, en particular, aplicado en sistemas para riego en agricultura, que estando instalado cerca de los aspersores, presenta un método de autolimpieza eficaz e inexistente hasta el momento. The present invention, as indicated in the title, refers to a device designed for the irrigation sector, in particular, applied in agricultural irrigation systems, which, when installed near the sprinklers, presents an effective and self-cleaning method. non-existent until now.
El objeto de esta invención es aportar una solución hasta ahora desconocida para vahos inconvenientes que se comentarán más adelante, principalmente, se pretende lograr un resultado final que permita a los usuarios de sistemas de riego ahorrar tiempo y trabajo al no tener que limpiar manualmente los filtros que corresponden a cada aspersor. The object of this invention is to provide a until now unknown solution for inconvenient mists that will be discussed later, mainly, it is intended to achieve a final result that allows users of irrigation systems to save time and work by not having to manually clean the filters. that correspond to each sprinkler.
El dispositivo en cuestión aporta esenciales características de novedad y notables ventajas con respecto a los medios conocidos y utilizados para los mismos fines en el estado actual de la técnica. The device in question provides essential novelty features and notable advantages with respect to the means known and used for the same purposes in the current state of the art.
Los sistemas de riego automático son ampliamente conocidos en el estado de la técnica. Aportan una gran ventaja a la hora de automatizar esta labor tan importante. Automatic irrigation systems are widely known in the state of the art. They provide a great advantage when it comes to automating this very important task.
Dichos sistemas son especialmente útiles en el campo y para la agricultura. Disponen tradicionalmente de un programador encargado de abrir o cerrar el paso del agua de una manera y a un tiempo determinado. El agua transcurre por la tubería hasta llegar a los aspersores, pasando antes por unos filtros cuya función es evitar que suciedad, insectos u objetos de cualquier tipo lleguen hasta el aspersor y lo taponen. These systems are especially useful in the countryside and for agriculture. They traditionally have a programmer in charge of opening or closing the water flow in a certain way and at a certain time. The water runs through the pipe until it reaches the sprinklers, first passing through filters whose function is to prevent dirt, insects or objects of any kind from reaching the sprinkler and clogging it.
El inconveniente de este mecanismo es que el usuario se ve obligado a hacer todo el recorrido a lo largo del sistema de riego, aspersor por aspersor, para limpiar cada filtro. The drawback of this mechanism is that the user is forced to go all the way along the irrigation system, sprinkler by sprinkler, to clean each filter.
Esto naturalmente conlleva un gran esfuerzo y mucho tiempo desperdiciado, especialmente en zonas con instalaciones de regadío muy amplias. This naturally entails great effort and a lot of wasted time, especially in areas with very extensive irrigation facilities.
Hasta el momento no se conocía un filtro provisto de un dispositivo capaz de autolimpiarse, evitando así una tarea tan tediosa como ir filtro a filtro para hacerlo manualmente. Until now, there was no known filter equipped with a device capable of self-cleaning, thus avoiding such a tedious task as going from filter to filter to do it manually.
El dispositivo que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, aportando una serie de ventajosas y novedosas características, y sin que ello suponga merma alguna de sus prestaciones en otros aspectos. La invención propuesta pretende aportar una solución económica, ecológica, práctica, sencilla y de fácil utilización, cuyo efecto sería un sistema de autolimpieza de los filtros para riego. The device that the invention proposes completely satisfactorily solves the problem previously explained, providing a series of advantageous and innovative characteristics, and without this affecting any of its benefits in other aspects. The proposed invention aims to provide an economical, ecological, practical, simple and easy-to-use solution, the effect of which would be a self-cleaning system for irrigation filters.
La presente invención tiene su campo de aplicación en el sector de las instalaciones de regadío. The present invention has its field of application in the sector of irrigation facilities.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el estado de la técnica encontramos algunos documentos relacionados con el sector de la invención en cuestión, aunque ninguno de ellos cumple la misma función ni aporta las mismas características ventajosas. In the state of the art we find some documents related to the sector of the invention in question, although none of them fulfill the same function or provide the same advantageous characteristics.
Así, en el documento ES 1 050 877 U encontramos un filtro autolimpiante, provisto de una carcasa cilindrica en cuyo interior se establece un cartucho filtrante a base de una pluralidad de discos ranurados, cartucho que define una cámara axial interior y una cámara exterior o envolvente, con la propia carcasa, de manera que el agua accede a la cámara envolvente de dicha entrada, atraviesa el cartucho filtrante y abandona el filtro por una salida situada en el mismo extremo de la carcasa que la entrada, caracterizado porque en el extremo de la carcasa opuesto a las citadas entrada y salida incorpora un oricio para salida del agua durante la fase de lavado, asistido por una válvula de paso, preferentemente automática, de manera que durante la fase de autolavado, en la que se invierte el sentido de circulación del agua a través del filtro, y esta pasa de la cámara axial a la cámara envolvente, el agua abandona el filtro a través de este oricio de salida, previa apertura de la correspondiente válvula. Thus, in document ES 1 050 877 U we find a self-cleaning filter, provided with a cylindrical casing inside the interior of which a filter cartridge is established based on a plurality of slotted discs, a cartridge that defines an inner axial chamber and an outer chamber or envelope. , with the housing itself, so that the water accesses the surrounding chamber of said inlet, passes through the filter cartridge and leaves the filter through an outlet located at the same end of the housing as the inlet, characterized in that at the end of the casing opposite the aforementioned inlet and outlet incorporates an opening for water outlet during the washing phase, assisted by a flow valve, preferably automatic, so that during the self-washing phase, in which the direction of circulation of the water through the filter, and it passes from the axial chamber to the surrounding chamber, the water leaves the filter through this outlet hole, after opening the corresponding valve.
Por otro lado, en el documento ES 2 053 985 se aporta una válvula de control de caudal con modulación de presión para mantener un caudal predeterminado casi constante de fluido desde una salida de la misma a pesar de las fluctuaciones de la presión de fluido transmitidas a una entrada de la misma; comprendiendo dicha válvula: una caja tubular que define un conducto circulatorio; un vástago elastómero de sección transversal circular que en condiciones de uso está montado en la mencionada caja dispuesto sobre un eje longitudinal de dicha caja y que tiene una parte maciza del cuerpo y al menos un conducto circulatorio a través del mismo; una sub cámara definida al menos en parte por el mencionado vástago y que se comunica con la mencionada entrada; y un diafragma flexible formado como parte integrante del mencionado vástago y superpuesto al mencionado conducto para separar la mencionada sub cámara del mencionado conducto circulatorio, para ser sometido a las mencionadas fluctuaciones de la presión del fluido y para flexionarse hacia el interior de dicho conducto circulatorio y vahar así el tamaño del mismo, estando dicho diafragma flexible definido por una superficie exterior de trabajo sobre el mismo, cuya superficie esta distanciada radialmente del mencionado conducto circulatorio hacia el exterior, para ser sometida a dichas fluctuaciones de la presión del fluido; estando la mencionada válvula de control de caudal caracterizada por el hecho de que: la superficie exterior de trabajo es un rebaje en el cuerpo del vástago, estando distanciada de la pared interior de la mencionada caja y definiendo parte de la mencionada subcámara, la superficie periférica exterior del vástago que es opuesta a la superficie exterior de trabajo con respecto al mencionado conducto, está en contacto con la pared interior de la mencionada caja, de forma tal que cuando el mencionado diafragma flexible se flexiona en respuesta a un incremento de la presión de fluido en la mencionada subcámara aplicado a dicha superficie exterior de trabajo, tiende a estrechar el mencionado conducto a base de flexionarse hacia la mencionada superficie periférica restante del mencionado vástago que está en contacto con la mencionada pared interior, siendo así el diafragma empujado hacia la mencionada pared interior, para mantener el caudal a la salida de la mencionada válvula al mencionado nivel de caudal predeterminado casi constante. On the other hand, document ES 2 053 985 provides a flow control valve with pressure modulation to maintain an almost constant predetermined flow rate of fluid from an outlet thereof despite fluctuations in fluid pressure transmitted to it. an entry thereof; said valve comprising: a tubular box that defines a circulatory conduit; an elastomeric stem of circular cross section that in use conditions is mounted in said box arranged on a longitudinal axis of said box and that has a solid part of the body and at least one circulatory conduit through it; a sub chamber defined at least in part by said stem and communicating with said entrance; and a flexible diaphragm formed as an integral part of said stem and superimposed on said conduit to separate said sub-chamber from said circulatory conduit, to be subjected to said fluid pressure fluctuations and to flex towards the interior of said circulatory conduit and thus varying its size, said flexible diaphragm being defined by a outer working surface thereon, whose surface is radially distanced from said circulatory conduit towards the outside, to be subjected to said fluid pressure fluctuations; said flow control valve being characterized by the fact that: the outer working surface is a recess in the body of the stem, being distanced from the inner wall of said box and defining part of said subchamber, the peripheral surface exterior of the stem that is opposite to the exterior working surface with respect to said conduit, is in contact with the interior wall of said box, such that when said flexible diaphragm flexes in response to an increase in pressure of fluid in said subchamber applied to said outer working surface, tends to narrow said conduit by flexing towards said remaining peripheral surface of said stem which is in contact with said inner wall, thus the diaphragm being pushed towards said inner wall, to maintain the flow at the outlet of said valve at said almost constant predetermined flow level.
A su vez, en el documento ES 1 059 225 U se reivindica un filtro autolimpiante perfeccionado para aguas de riego agrícola, de los que disponen de una carcasa de configuración cilindrica o cuerpo donde se acopla un conducto de entrada que se comunica con la cámara exterior o perimetral del mismo, y uno o dos conductos de salida que están comunicados con la cámara interior o axial, separadas estas dos cámaras coaxiales, una exterior y la otra interior, por un bastidor de discos rasurados encargados del filtrado del fluido, formando estos discos un paquete debidamente presionados en sentido axial, y siendo estos filtros aplicables a los que se limpian automáticamente al invertir el flujo y separar las anillas para la expulsión de las partículas retenidas en los micro canales de las anillas, caracterizado por disponer de una base de las anillas atravesada por los tubos perforados, que limpian las anillas, permitiendo el libre movimiento axial de los tubos y presentando en el extremo opuesto los tubos una base superior, que presiona las anillas en sentido axial, mientras que la base inferior genera el empuje axial para separar las anillas y presionarlas, actuando como obturador y permitiendo el paso de flujo a los tubos perforados en una operación de autolimpieza. In turn, document ES 1 059 225 U claims an improved self-cleaning filter for agricultural irrigation water, which has a cylindrical configuration housing or body where an inlet conduit is attached that communicates with the exterior chamber. or perimeter thereof, and one or two outlet ducts that are connected to the interior or axial chamber, these two coaxial chambers being separated, one exterior and the other interior, by a frame of shaved discs responsible for filtering the fluid, forming these discs a package duly pressed in an axial direction, and these filters being applicable to those that are automatically cleaned by reversing the flow and separating the rings for the expulsion of the particles retained in the micro channels of the rings, characterized by having a base of the rings crossed by the perforated tubes, which clean the rings, allowing free axial movement of the tubes and presenting at the opposite end of the tubes an upper base, which presses the rings in an axial direction, while the lower base generates the axial thrust to separate the rings and press them, acting as a shutter and allowing flow to pass through the perforated tubes in a self-cleaning operation.
En estos documentos encontramos dispositivos que por su complejidad, tamaño o funcionalidad no son capaces de actuar como autolimpiantes en filtros de riego. In these documents we find devices that due to their complexity, size or functionality are not capable of acting as self-cleaners in irrigation filters.
Así vemos, que hasta ahora no se conocía un dispositivo que por sus novedosas características resuelva los inconvenientes mencionados anteriormente tanto en cuanto a los documentos citados como a otras invenciones o sistemas tradicionales que encontramos en el estado de la técnica. Thus we see that until now there was no known device that, due to its innovative characteristics, solves the drawbacks mentioned above both in terms of to the cited documents as well as to other inventions or traditional systems that we find in the state of the art.
Tomando en consideración los casos mencionados y analizados los argumentos conjugados, con la invención que se propone en este documento se da lugar a un resultado final en el que se aportan aspectos diferenciadores significativos frente al estado de la técnica actual, y donde se aportan una serie de avances en los elementos ya conocidos con sus ventajas correspondientes. Taking into consideration the cases mentioned and the combined arguments analyzed, the invention proposed in this document gives rise to a final result in which significant differentiating aspects are provided compared to the current state of the art, and where a series of of advances in already known elements with their corresponding advantages.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Así, la presente invención está constituida a partir de los siguientes elementos:Thus, the present invention is made up of the following elements:
Una válvula consistente en un cuerpo preferiblemente tubular encajado por uno de sus extremos a una espiga con filtro en una caña de riego con aspersor, albergando dicho cuerpo un mecanismo de apertura o cierre perpendicular con respecto a éste como una seta, plaqueta, mebrana u otro, siendo susceptible dicho mecanismo de actuar sobre un muelle longitudinal cónico, tarado para cierre a 3 bares de presión, presente entre el mecanismo de apertura y cierre y la abertura de salida, estando la válvula abierta cuando el sistema de riego se encuentra en modo de reposo, y cerrada cuando se encuentra en funcionamiento. A valve consisting of a preferably tubular body fitted at one of its ends to a spigot with a filter in an irrigation cane with a sprinkler, said body housing an opening or closing mechanism perpendicular to it such as a mushroom, platelet, membrane or other , said mechanism being capable of acting on a conical longitudinal spring, set to close at 3 bars of pressure, present between the opening and closing mechanism and the outlet opening, the valve being open when the irrigation system is in shut-off mode. rest, and closed when in operation.
El funcionamiento es sencillo. El filtro acumula cal, mejillón o cualquier tipo de suciedad u objetos. Cuando se pone en funcionamiento el sistema de riego, al llegar el agua con poca presión durante los primeros segundos, se elimina su contenido a través de la abertura de salida de la válvula. Una vez transcurridos estos segundos y limpiado el filtro, el agua llega al filtro con una presión estándar actuando sobre el mecanismo de apertura y cierre que, a su vez, actúa sobre el muelle taponando la abertura de salida impidiendo que el agua siga saliendo por la válvula. The operation is simple. The filter accumulates lime, mussels or any type of dirt or objects. When the irrigation system is put into operation, as the water arrives at low pressure during the first seconds, its contents are eliminated through the outlet opening of the valve. Once these seconds have passed and the filter has been cleaned, the water reaches the filter with a standard pressure acting on the mechanism of opening and closing which, in turn, acts on the spring, plugging the outlet opening, preventing water from continuing to come out of the valve.
Cuando el sistema de riego deja de estar en funcionamiento, la presión baja y el mecanismo de apertura y cierre se desliza abriendo nuevamente la válvula, volviendo a lavar los restos depositados durante el riego que acaba de hacer. When the irrigation system stops operating, the pressure drops and the opening and closing mechanism slides, opening the valve again, washing away the remains deposited during the irrigation that has just been done.
