DESCRIPCIÓN DESCRIPTION
Canalón plástico de drenaje para cultivo hortícola en saco de sustrato. Plastic drainage channel for horticultural cultivation in a substrate bag.
SECTOR DE LA TÉCNICA TECHNICAL SECTOR
La presente invención se refiere a un canalón plástico de drenaje para cultivo hortícola de tipo hidropónico, en saco de sustrato, destinado a ser instalado en suelo inclinado bajo invernadero. The present invention relates to a plastic drainage gutter for hydroponic horticultural cultivation, in a substrate bag, intended to be installed on sloping ground under a greenhouse.
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
El objeto de la invención es proporcionar un sistema de soporte de los sacos de sustrato así como de drenaje del agua que se constituya a partir de un único elemento monopieza y modular, fácilmente acoplable a otros dispositivos del mismo tipo, que reduzca el uso de plástico por metro lineal, sea fácil de instalar, altamente estable, duradero, con menor mantenimiento y máxima estabilidad para el saco. The object of the invention is to provide a system for supporting substrate bags and for draining water, which is made up of a single, modular, one-piece element, easily coupled to other devices of the same type, which reduces the use of plastic per linear meter, is easy to install, highly stable, durable, requires less maintenance and has maximum stability for the bag.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el ámbito de aplicación práctica de la invención, se conocen canalones plásticos destinados a recoger el agua drenada proveniente de los sacos de sustrato, para ser transportada hasta el final de la línea, donde será recogida por un sumidero y recirculada posteriormente. In the field of practical application of the invention, plastic gutters are known for collecting the drained water from the substrate bags, to be transported to the end of the line, where it will be collected by a sump and subsequently recirculated.
La mayoría de los canalones conocidos corresponde a una lámina de polipropileno de entre 0,7 y 0,8 mm de espesor, servido en formato bobina continua, con dos marcas de doblez en sus laterales, para posteriormente permitir el abatimiento de dichos laterales y formar así unas paredes de contención lateral durante la instalación en invernadero. Most of the known gutters correspond to a polypropylene sheet between 0.7 and 0.8 mm thick, supplied in continuous coil format, with two fold marks on its sides, to later allow the folding of said sides and thus form lateral containment walls during installation in the greenhouse.
Sin embargo, para evitar que las raíces que puedan sobresalir interiormente del saco estén en constante contacto con el flujo de agua que circula por el canalón, se utilizan estructuras elevadoras que se insertan en el canalón que elevan dicho saco, sin apenas interferir en el flujo de agua a su través. Un dispositivo separador de este tipo se describe en el documento WO9956527. A mayor abundamiento, los laterales del canalón deben ser estabilizados para asegurar su retención lateral y evitar pérdidas de agua, utilizándose para ello piezas adicionales que se acoplan sobre dichos laterales en orden a estabilizar el conjunto. Un sistema de este tipo se describe en la patente de invención EP 2997818A1 . However, in order to prevent the roots that may protrude from the inside of the bag from being in constant contact with the flow of water circulating through the gutter, lifting structures are used that are inserted into the gutter and raise said bag, without hardly interfering with the flow of water through it. A separating device of this type is described in document WO9956527. Furthermore, the sides of the gutter must be stabilised to ensure lateral retention and prevent water loss, using additional parts that are fitted to said sides in order to stabilise the assembly. A system of this type is described in patent EP 2997818A1.
Se trata pues de sistemas complejos, en los que participan muchas piezas y que consecuentemente resulta caros y difíciles de instalar. These are complex systems, which involve many parts and are therefore expensive and difficult to install.
Tratando de solucionar esta problemática, en el documento NL7807559A se describe un canalón en el que participan dos paredes laterales longitudinales y un cuerpo central aplanado, en el que se establecen una serie de protuberancias o perfil almenado que si bien presenta un carácter monopieza, presenta una problemática a la hora de ser apilado, ya que la configuración de sus paredes laterales impide una ocupación volumétrica mínima en dicho apilado, a lo que hay que añadir el hecho de que las citadas paredes laterales no incluyen costillas de refuerzo lateral, lo que obliga a obtener este tipo de canalones en materiales metálicos o plásticos de gran espesor de pared lo que supone un sobrecosto de materiales a todas luces indeseable. In an attempt to solve this problem, document NL7807559A describes a gutter comprising two longitudinal side walls and a flattened central body, in which a series of protuberances or crenellated profile are established which, although it is a single-piece structure, presents a problem when it comes to being stacked, since the configuration of its side walls prevents a minimum volumetric occupation in said stacking, to which must be added the fact that the aforementioned side walls do not include lateral reinforcement ribs, which forces this type of gutter to be obtained in metallic or plastic materials with a high wall thickness, which entails an additional cost of materials that is clearly undesirable.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
El canalón plástico de drenaje para cultivo hortícola en saco de sustrato que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, ofreciendo un elemento monopieza, obtenido en plástico por termoformado, con un espesor mínimo que redunda en un mínimo gasto de materiales, fácil de instalar, apilable con una ocupación volumétrica mínima, y sumamente efectivo en situación operativa. The plastic drainage channel for horticultural cultivation in a substrate bag proposed by the invention fully satisfactorily resolves the problem described above, offering a single-piece element, obtained in plastic by thermoforming, with a minimum thickness that results in a minimum expenditure of materials, easy to install, stackable with a minimum volumetric occupation, and extremely effective in operational situations.
Para ello, el canalón de la invención se constituye a partir de un cuerpo esencialmente laminar de material plástico, preferentemente rectangular alargado, en el que se definen dos líneas paralelas de plegado longitudinales, por termoconformado, determinantes de dos sectores laterales plegables que definen unas paredes laterales y un sector central mayoritaho, es decir, que dicho sector central presenta una mayor extensión que cada uno de los sectores laterales. For this purpose, the gutter of the invention is made from an essentially laminar body of plastic material, preferably elongated rectangular, in which two parallel longitudinal folding lines are defined, by thermoforming, determining two foldable lateral sectors that define side walls and a larger central sector, that is, said central sector has a greater extension than each of the lateral sectors.
De forma más concreta, se ha previsto que sobre el sector central del cuerpo del canalón se distribuyan unas protuberancias obtenidas en el termoformado del canalón y que emergen superiormente, determinando elementos de soporte y separación para el saco de sustrato con respecto al fondo del canalón por el que está destinado a fluir el agua de riego. More specifically, it has been planned that on the central section of the gutter body distribute some protuberances obtained in the thermoforming of the gutter and that emerge from above, determining support and separation elements for the substrate bag with respect to the bottom of the gutter through which the irrigation water is intended to flow.
De acuerdo con una de las características esenciales de la invención se ha previsto que de los sectores laterales plegables del cuerpo del canalón emerjan interiormente unas protuberancias que definen unas costillas de refuerzo para las paredes laterales del canalón. Así, en situación operativa, las citadas costillas determinan medios de retención lateral y refuerzo para mantener la posición vertical de las paredes laterales del canalón. In accordance with one of the essential characteristics of the invention, it has been provided that the foldable lateral sectors of the gutter body have protuberances that define reinforcing ribs for the gutter's side walls. Thus, in an operational situation, the aforementioned ribs determine lateral retention and reinforcement means to maintain the vertical position of the gutter's side walls.
Dichas costillas al emerger en dirección opuesta a las protuberancias del sector central, hacen que la instalación resulte sumamente rápida y sencilla, ya que en situación inicial el dispositivo presentará una disposición aplanada, sobreelevada con respecto del suelo por efecto de las citadas costillas de refuerzo que sobresalen interiormente. Así, el propio apoyo del saco sobre las protuberancias del sector central provocará el doblado automático de las paredes o sectores laterales abrazando al saco. Igualmente, en esta maniobra se posibilita la estabilización de las paredes laterales a través de las citadas costillas que impedirán que dichas paredes laterales puedan tender hacia su posición original, asegurando así la contención lateral del agua que fluye a través del canalón, ofreciendo una estabilidad lateral que hasta la fecha no ofrece ningún otro dispositivo conocido. These ribs emerge in the opposite direction to the protuberances of the central sector, making installation extremely quick and easy, since in the initial situation the device will have a flattened layout, raised with respect to the ground due to the effect of the aforementioned reinforcing ribs that protrude internally. Thus, the support of the bag on the protuberances of the central sector will cause the automatic bending of the walls or side sectors embracing the bag. Likewise, this maneuver makes it possible to stabilize the side walls through the aforementioned ribs that will prevent said side walls from tending towards their original position, thus ensuring lateral containment of the water that flows through the gutter, offering lateral stability that no other known device offers to date.
Tal y como se ha dicho anteriormente, el dispositivo presenta una configuración preferentemente rectangular alargada, y está destinado a poder acoplarse a otros dispositivos del mismo tipo mediante solapamiento parcial en una superficie inclinada, de forma análoga a como se lleva a cabo con las tejas de tejados, de modo que en correspondencia con sus extremos anterior y posterior incluye unas torretas en función de protuberancias complementarias, de forma que constituyen los elementos de empalme que encajan a la perfección y crean un apilamiento sin ningún hueco, de manera que, si se sigue la inclinación del terreno establecida, no existen fugas de agua. As previously stated, the device preferably has an elongated rectangular configuration, and is intended to be able to be coupled to other devices of the same type by partial overlapping on an inclined surface, in a manner similar to that carried out with roof tiles, so that in correspondence with its front and rear ends it includes turrets in the function of complementary protuberances, such that they constitute the splicing elements that fit perfectly and create a stack without any gap, such that, if the established slope of the ground is followed, there are no water leaks.
Este efecto se potencia al colocar los sacos de sustrato encima de las torretas, donde debido al peso ejercido sobre estas, el sellado o presión en el empalme es mayor. This effect is enhanced by placing the substrate bags on top of the turrets, where due to the weight exerted on them, the sealing or pressure on the joint is greater.
Ventajosamente, las torretas se han diseñado de manera que sea imposible colocarlas de la forma incorrecta, ya que a la torreta que debe ir encima se le añaden unos relieves externos en la base que hacen de tope en el apilamiento incorrecto, evidenciando que dicha posición no es la correcta, mientras que en la posición correcta de ensamblaje, estos elementos no suponen obstáculo alguno al quedar dispuestos externamente sobre la cara superior. Advantageously, the turrets have been designed in such a way that it is impossible to place them incorrectly, since external reliefs are added to the turret that must go on top. at the base that act as a stop in incorrect stacking, showing that this position is not correct, while in the correct assembly position, these elements do not pose any obstacle as they are arranged externally on the upper face.
A partir de esta estructuración, se derivan las siguientes ventajas: The following advantages arise from this structure:
• Reducción en el número de componentes que componen el sistema de drenaje. • Reduction in the number of components that make up the drainage system.
• Reducción en el uso de plástico por metro lineal. • Reduction in the use of plastic per linear meter.
• Instalación más rápida. • Faster installation.
• Estabilidad de las paredes laterales y la imposibilidad de que estas se vayan abriendo con el paso del tiempo. • Stability of the side walls and the impossibility of them opening over time.
• Menor mantenimiento. • Less maintenance.
• Las líneas de plegado de las paredes laterales se obtienen por termoformado en vez de mediante troquelado o marcado a presión, por lo que son menos frágiles y por lo tanto menos susceptibles de roturas y fugas. • The fold lines on the side walls are obtained by thermoforming rather than by die-cutting or pressure scoring, so they are less fragile and therefore less susceptible to breakage and leaks.
• Mayor durabilidad. • Greater durability.
• Las paredes laterales “abrazan” el saco impidiendo que caigan hojas secas y frutos en el canal contaminando el agua. • The side walls “hug” the bag, preventing dry leaves and fruits from falling into the channel and contaminating the water.
• Aporta mayor estabilidad al saco. • Provides greater stability to the bag.
• El diseño del canalón permite ejecutar un desarrollo o termoformado continuo del canalón. • The design of the gutter allows for continuous development or thermoforming of the gutter.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas, puede observarse que el canalón de la invención se constituye a partir de un cuerpo laminar de material plástico, rectangular alargado, en el que se definen dos líneas paralelas de plegado (1 ) longitudinales determinantes de dos sectores o paredes laterales (2) plegables y un sector central (3) mayohtaho respecto las paredes laterales. In view of the figures shown, it can be observed that the gutter of the invention is made from a rectangular elongated plastic sheet body, in which two parallel longitudinal folding lines (1) are defined, determining two foldable sectors or side walls (2) and a central sector (3) higher than the walls. sides.
Cada canalón, a modo meramente ejemplario, podría presentar una longitud de entre los 100 cm a los 12 m (el límite lo ponen los medios de almacenamiento/transporte), ya que se pueden termoformar en continuo. Each gutter, as a mere example, could have a length of between 100 cm and 12 m (the limit is set by the means of storage/transport), since they can be thermoformed continuously.
Sobre el sector central (3) se distribuyen una serie de protuberancias (4) de configuración preferentemente tronco-piramidal, para permitir un apilamiento entre canalones con una ocupación volumétrica mínima, sin espacios intermedios. On the central sector (3) a series of protuberances (4) are distributed, preferably in a truncated-pyramidal configuration, to allow stacking between gutters with a minimum volumetric occupation, without intermediate spaces.
Estas protuberancias (4) sobresalen del sector central (3) en sentido superior o ascendente, mientras que de los sectores laterales (2) emergen en sentido inferior o descendente una pluralidad de costillas (5) - que esencialmente también representan protuberancias -. Como se puede ver en las figuras 6 y 7, cuando se deposita el saco (6) de sustrato sobre las protuberancias (4), que ofrece una función de elementos separadores para dicho saco (6), el peso del mismo provoca que las paredes laterales (2) se plieguen sobre los laterales del saco (6), abrazándolo, mientras que las costillas (5) pasan a una posición operativa en la que determinan medios de retención lateral y refuerzo para mantener la posición vertical de los sectores laterales (2), impidiendo que éstas puedan volver a su posición original. These protuberances (4) protrude from the central sector (3) in an upward or ascending direction, while from the lateral sectors (2) emerge in an inferior or descending direction a plurality of ribs (5) - which essentially also represent protuberances -. As can be seen in figures 6 and 7, when the substrate bag (6) is placed on the protuberances (4), which serve as separating elements for said bag (6), the weight of the same causes the side walls (2) to fold over the sides of the bag (6), embracing it, while the ribs (5) move to an operative position in which they determine lateral retention and reinforcement means to maintain the vertical position of the lateral sectors (2), preventing them from returning to their original position.
Tal y como se puede ver en las figuras 3 y 4, en los bordes o extremos (7) y (8) del canalón se ha previsto que se incluyan medios de acoplamiento entre canalones mediante solapamiento parcial de los mismos y disposición sobre una superficie inclinada, y que se materializan en unas protuberancias complementarias a modo de elementos de empalme denominadas torretas inferiores (9) y torretas superiores (10), respectivamente, destinadas a encajar entre sí, de configuración preferentemente tronco-piramidal. Así pues, los medios de acoplamiento materializados en torretas inferiores (9) y torretas superiores (10) están destinadas a encajar entre sí y, por tanto, están dispuestas, respectivamente, en los bordes opuestos (7) y (8) del canalón. As can be seen in figures 3 and 4, the edges or ends (7) and (8) of the gutter have been provided with coupling means between gutters by means of partial overlapping of the same and arrangement on an inclined surface, and which are materialized in complementary protuberances as joining elements called lower turrets (9) and upper turrets (10), respectively, intended to fit together, preferably of a truncated-pyramidal configuration. Thus, the coupling means materialized in lower turrets (9) and upper turrets (10) are intended to fit together and, therefore, are arranged, respectively, on the opposite edges (7) and (8) of the gutter.
Por otro lado, el sector central (3) incluirá preferentemente unas marcaciones (12) que determinan el sentido de flujo del agua en virtud de la inclinación prevista en la instalación del cultivo hortícola, de modo que las torretas inferiores (9) siempre queden dispuestas por debajo de las torretas superiores (10), encajándose entre sí. Para ello, las torretas superiores (10) incluyen unos relieves (1 1 ) externos que determinan una única posición posible de acoplamiento con respecto a las torretas interiores (9), por lo que impiden el adecuado acoplamiento entre estos elementos evidenciando que la posición correcta es aquella en la que éstas quedan dispuestas por encima de las torretas inferiores (9), de forma análoga a como se montan las tejas de un tejado. On the other hand, the central sector (3) will preferably include markings (12) that determine the direction of water flow by virtue of the inclination planned in the installation of the horticultural crop, so that the lower turrets (9) are always arranged below the upper turrets (10), fitting together. To this end, the upper turrets (10) include external reliefs (1 1 ) that determine a single possible position of the water flow. coupling with respect to the interior turrets (9), which prevents proper coupling between these elements, showing that the correct position is one in which they are arranged above the lower turrets (9), in a similar way to how the tiles of a roof are mounted.
Por todo lo anterior, se consigue de esta forma un canalón muy fácil de implantar, sumamente efectivo y económico y constituido por una sola pieza. For all the above reasons, this results in a gutter that is very easy to install, extremely effective and economical and made up of a single piece.
