DESCRIPCIÓNDESCRIPTION

OBJETO DE LA INVENCION OBJECT OF THE INVENTION

Es objeto de la presente invención es, tal y como el título establece, proveer tanto un dispositivo como el procedimiento para el muestreo representativo de gases y materia disuelta y particulada, es decir, en forma de partículas, contenida en una masa de agua.  The object of the present invention is, as the title states, to provide both a device and the method for representative sampling of gases and dissolved and particulate matter, that is, in the form of particles, contained in a body of water.

La presente invención está caracterizada por los detalles constructivos que presenta el dispositivo, los cuales posibilitan la toma de muestras representativas de gases y materia disuelta y particulada contenida en una m asa d e ag ua, así como conseguir un sistema de cierre novedoso caracterizado por la ausencia de látex interno o muelles de tracción externos redundando en una independencia en la fuerza de cierre entre ambas bocas. Por lo tanto, la presente invención se circunscribe dentro del ámbito de la tecnología e instrumentación oceanográfica. The present invention is characterized by the constructive details presented by the device, which make it possible to take representative samples of gases and dissolved and particulate matter contained in a water handle, as well as to achieve a novel closure system characterized by the absence of internal latex or external traction springs resulting in an independence in the closing force between both mouths. Therefore, the present invention is circumscribed within the field of oceanographic technology and instrumentation.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Actualmente, durante una expedición a bordo de un buque oceanográfico, existen dos maneras de recoger volúmenes considerables de agua: las botellas oceanógraficas y las bombas de succión. Currently, during an expedition aboard an oceanographic vessel, there are two ways to collect considerable volumes of water: oceanographic bottles and suction pumps.

Las bombas de succión se utilizan cuando se requieren grandes volúmenes de agua debido a que estos dispositivos pueden ser utilizados incluso con el barco en movimiento. Sin embargo, las bombas de succión están lim itadas a los primeros metros de la columna de agua debido a la complejidad de su manejo e imprecisión en la determ inación de su profundidad exacta a la hora de obtener las muestras. Suction pumps are used when large volumes of water are required because these devices can be used even with the ship moving. However, the suction pumps are limited to the first meters of the water column due to the complexity of their handling and inaccuracy in determining its exact depth at the time of obtaining the samples.

El dispositivo de referencia para la toma de muestras de agua a cualquier profundidad es la botella oceanógrafica (como las patentes US50941 13; US 4846004, U S4037477 y US3815422). De forma genérica estos dispositivos consisten en un cilindro con dos tapas en los extremos, un tapón de venteo superior y una salida de agua en la parte inferior de la botella. Cuando se toma una muestra de agua de los océanos ésta contiene gases, matena disuelta y particulada. Tanto los gases como la materia disuelta tienen un comportamiento lagrangiano, es decir, se mueven con la masa de agua. Sin em bargo, la materia particulada está operacionalmente dividida en dos categorías: suspendida y que sedimenta. La materia particulada suspendida tiene una dinámica similar a los gases y a la materia disuelta moviéndose en el seno de la masa de agua. Por el contrario, la materia particulada que sedimenta presenta unas tasas de sedimentación vertical que le infieren un comportamiento dinámico totalmente diferente. Las tasas de sedimentación de las partículas en el océano están determinadas por las diferencias de densidad entre las mismas y el agua que las rodea. Resultados recientes muestran que las velocidades de sedimentación de las partículas en el océano varían entre <0,7 m/d y >980 m/d (Alonso-González et al., 2010). Asumiendo una velocidad promedio de la materia que sedimenta en el océano de 100 m/d, las partículas recogidas por las botellas oceanógraficas actuales se encuentran depositadas en el fondo de las mismas en unos 14 minutos. Sin embargo, los perfiles de muestreo suelen durar un promedio de 2- 4 horas, dependiendo de la profundidad, por lo que toda la materia que sedimenta se encuentra en el fondo de la botella al llegar ésta a superficie. The reference device for sampling water at any depth is the oceanographic bottle (such as US50941 13; US 4846004, U S4037477 and US3815422). In general, these devices consist of a cylinder with two end caps, an upper vent plug and a water outlet at the bottom of the bottle. When a sample of ocean water is taken, it contains gases, dissolved and particulate matena. Both gases and dissolved matter have a Lagrangian behavior, that is, they move with the body of water. However, particulate matter is operationally divided into two categories: suspended and settling. Suspended particulate matter has a dynamic similar to gases and dissolved matter moving within the body of water. On the contrary, the sediment particulate matter has vertical sedimentation rates that infer a totally different dynamic behavior. The sedimentation rates of the particles in the ocean are determined by the differences in density between them and the surrounding water. Recent results show that sedimentation rates of particles in the ocean vary between <0.7 m / d and> 980 m / d (Alonso-González et al., 2010). Assuming an average velocity of the material that sediments in the ocean of 100 m / d, the particles collected by the current oceanographic bottles are deposited at the bottom of them in about 14 minutes. However, the sampling profiles usually last an average of 2-4 hours, depending on the depth, so that all the sedimentation material is at the bottom of the bottle when it reaches the surface.

El problema radica en que, según el protocolo establecido, se muestrean primero los gases (O2, CO2, etc. , ) y material disuelto (pH, Alcalinidad, etc.,), extrayendo, en los dispositivos actuales, todo el material particulado que ha sedimentado durante este proceso. Esto implica que cuando se muestrean posteriormente los parámetros asociados al material que sedimenta (matena orgánica particulada, fitoplancton, zooplancton, etc. , ), éstos están siendo drásticamente subestimados. The problem is that, according to the established protocol, the gases (O2, CO2, etc.,) and dissolved material (pH, Alkalinity, etc.,) are first sampled, extracting, in the current devices, all the particulate material that has settled during this process. This implies that when the parameters associated with the sedimentation material are subsequently sampled (particulate organic matena, phytoplankton, zooplankton, etc.), they are being drastically underestimated.

Por lo tanto, es objeto de la presente solicitud superar los inconvenientes derivados de la geometría y características constructivas que presentan las botellas oceanográficas actuales, con el objetivo de evitar una subestimación de los parámetros asociados al material que sedimenta, es decir, se buscan unos dispositivos capaces de obtener una m uestra de agua a cualquier profundidad representativa de todas las clases de materia además de mejorar aspectos funcionales relativos al sistema de cierre, manejabilidad, evitar incrustaciones de partículas, etc., desarrollando un dispositivo como el que a continuación se describe, quedando su esencialidad recogida en la reivindicación primera.  Therefore, it is the object of the present application to overcome the inconveniences arising from the geometry and construction characteristics presented by the current oceanographic bottles, with the aim of avoiding an underestimation of the parameters associated with the sedimentation material, that is, devices capable of obtaining a sample of water at any representative depth of all kinds of matter in addition to improving functional aspects related to the closure system, manageability, avoiding particle encrustation, etc., developing a device such as the one described below, remaining its essentiality set forth in the first claim.

DESCRIPCIÓN DE LA INVENCIÓN El dispositivo de muestreo de agua de la presente invención comprende: DESCRIPTION OF THE INVENTION The water sampling device of the present invention comprises:

- Un cuerpo cilindrico, a modo de cámara/reservorio, abierto en ambos extremos, con terminaciones reducidas o no, fabricado de una sola pieza y con varios insertos para la unión de las partes auxiliares.  - A cylindrical body, as a chamber / reservoir, open at both ends, with reduced or non-terminated terminations, manufactured in one piece and with several inserts for joining auxiliary parts.

- Un sistema de cierre en cada uno de los extremos del dispositivo que comprende cada uno:  - A closure system at each end of the device comprising each one:

o un acople con aberturas laterales y provisto de un asiento con una junta tórica para el sellado de la cámara,  or a coupling with side openings and provided with a seat with an O-ring for sealing the chamber,

o un eje giratorio que desplaza lateralmente y coloca el sello de la cámara  or a rotating shaft that moves laterally and places the camera seal

o un pistón pivotante de cabeza semiesférica que realiza el sellado de la cámara gracias a la fuerza de un muelle de compresión y otro de torsión. - Un anclaje removible compatible con la mayoría de las rosetas que existen en el mercado y para su uso en una línea oceanográfica. or a semi-spherical pivoting piston that seals the chamber thanks to the force of a compression spring and a torsion spring. - A removable anchor compatible with most of the rosettes that exist in the market and for use in an oceanographic line.

- Múltiples entradas/salidas de agua y gases  - Multiple water / gas inlets / outlets

Además, el dispositivo de manera complementaria puede contar con un asa removible para facilitar la manipulación del dispositivo o botella de toma de muestras oceanográficas. In addition, the device can additionally have a removable handle to facilitate the handling of the oceanographic sampling device or bottle.

Con el objetivo de solucionar el problema de la subestimación del material particulado que sedimenta en las actuales botellas, el cuerpo del dispositivo de la presente invención presenta múltiples salidas y entradas de materia a diferentes niveles con funciones diferenciadas. Como mínimo presentará: In order to solve the problem of underestimating the particulate material that settles in the current bottles, the body of the device of the present invention has multiple outputs and inputs of matter at different levels with differentiated functions. At a minimum it will present:

- una entrada de aire o cualquier otro gas inerte (He, Ar, etc.), para evitar contaminación atmosférica, como puerto de venteo. Este puerto de venteo también puede ser usado para la toma de muestras de gases que presente la muestra de agua.  - an air inlet or any other inert gas (He, Ar, etc.), to avoid air pollution, such as a venting port. This venting port can also be used for the sampling of gases that the water sample presents.

- U na sal ida de agua a n ivel med io del cuerpo para el m uestreo preferencial de material disuelto y suspendido.  - A water outlet at the medium level of the body for preferential sampling of dissolved and suspended material.

- Una salida de agua en la parte inferior del cuerpo para el muestreo preferencial de material particulado que sedimenta.  - A water outlet in the lower part of the body for preferential sampling of sediment particulate material.

Por otro lado, y derivado del hecho de ser fabricado de una sola pieza, se eliminan las uniones encoladas de las actuales botellas, las cuales facilitan la adherencia de partículas a las mismas, subestimando la concentración de partículas en las muestras de agua. Así mismo, la técnica de fabricación mediante molde permite que el cuerpo del dispositivo esté constituido por múltiples capas. Como mínimo se plantea una bicapa; una capa interna de color oscuro para evitar la penetración de la luz a bajos espesores de pared y una capa externa de color claro para maximizar el efecto albedo y disminuir así el calentamiento de la muestra de agua por parte de la radiación solar. El funcionam iento del dispositivo de la presente invención se basa en la canalización del flujo de agua a través del cuerpo originado por el ascenso de la roseta oceanográfica hasta que el operario decide cerrar el dispositivo a la profundidad seleccionada mediante la activación remota del sistema de disparo de botellas que presentan las rosetas oceanógraficas. En ese momento, el muelle de torsión instalado en ambos extremos desplaza el pistón de cabeza sem iesférica hacia el cierre del d ispositivo a la vez q ue el m ue l le de compresión actúa para realizar su sellado contra la tonca. Este sistema de cierre permite la liberación de la sobrepresion al ascender el dispositivo hacia la superficie además de presentar independencia en la fuerza de cierre entre ambas bocas. On the other hand, and derived from the fact of being manufactured in one piece, the glued joints of the current bottles are eliminated, which facilitate the adhesion of particles to them, underestimating the concentration of particles in the water samples. Likewise, the mold manufacturing technique allows the body of the device to consist of multiple layers. At least one bilayer is raised; an inner layer of dark color to avoid the penetration of light at low wall thicknesses and an outer layer of light color to maximize the albedo effect and thus decrease the heating of the water sample by solar radiation. The operation of the device of the present invention is based on the channeling of the flow of water through the body caused by the rise of the oceanographic rosette until the operator decides to close the device to the selected depth by remotely activating the firing system. of bottles featuring oceanographic rosettes. At that time, the torsion spring installed at both ends moves the hemispherical head piston towards the device closing while the compression mechanism acts to seal it against the tonca. This closing system allows the release of the overpressure when the device ascends to the surface, besides presenting independence in the closing force between both mouths.

El procedimiento asociado al dispositivo de la presente invención se refiere a la manera de proceder en la toma de m uestras de agua procedentes del dispositivo de la presente invención. El procedimiento de toma de muestras es el establecido internacionalmente, primero se toman muestras de agua para el análisis de gases y matenal disuelto y posteriormente de material particulado que sedimenta. Sin embargo, cada muestra será tomada de la salida de agua apropiada a su fin; así las muestras para análisis de gases disueltos y materia disuelta y suspendida serán tomadas de la salida situada a nivel medio del cuerpo, mientras que las muestras para mediciones de materia particulada que sedimenta serán tomadas de la salida situada en la parte inferior del cuerpo. La salida/entrada de gases situada en la parte superior del cuerpo, permite la entrada de aire atmosférico a modo de venteo o puede ser utilizada para la inyección de un gas inerte con el mismo fin pero sin contaminación atmosférica. The procedure associated with the device of the present invention refers to the manner of proceeding in the collection of water samples from the device of the present invention. The sampling procedure is the one established internationally, water samples are first taken for the analysis of gases and dissolved matenal and subsequently of sediment particulate material. However, each sample will be taken from the appropriate water outlet to its end; thus the samples for analysis of dissolved gases and dissolved and suspended matter will be taken from the outlet located at the middle level of the body, while samples for measurements of sediment particulate matter will be taken from the outlet located in the lower part of the body. The gas outlet / inlet located in the upper part of the body, allows the entry of atmospheric air as a vent or can be used for the injection of an inert gas for the same purpose but without air pollution.

Con esta metodología de muestreo se consigue que las partículas que han sedimentado en la parte inferior de la botella no sean extraídas durante la toma de muestras para el análisis de gases o materia disuelta. Por lo tanto, gracias al dispositivo y procedimiento asociado de la presente invención, se consigue de manera principal las siguientes ventajas científico-técnicas: - Evitar la subestimación de los parámetros asociados al material que sedimenta durante el proceso de extracción de muestras. With this sampling methodology it is possible that the particles that have settled in the lower part of the bottle are not extracted during the sampling for the analysis of gases or dissolved matter. Therefore, thanks to the device and associated procedure of the present invention, the following scientific-technical advantages are achieved in a main way: - Avoid underestimating the parameters associated with the material that settles during the sample extraction process.

- Cuerpo del dispositivo fabricado de una sola pieza, evitando así las incrustaciones de partículas en el mismo.  - Body of the device manufactured in one piece, thus avoiding the encrustation of particles in it.

Debido a la gran cantidad de m uestras de agua de pequeños volúmenes que se toman actualmente, se han diseñado las válvulas de salida de agua de manera que al dejar de presionarlas se cierran automáticamente. Para la toma de muestras de agua de mayor volumen presentan la opción de bloqueo en posición abierta. Also, this manufacturing technique allows custom manufacturing of the device by the customer (color, wall thickness, material, etc.). - The device consists of at least one bilayer; an inner layer of dark color to avoid light penetration at low wall thicknesses and an outer layer of light color to maximize the albedo effect and thus decrease the heating of the water sample. - The device has water outlet valves with automated closing.

The possibility of manufacturing in different colors can be used for the differentiation of use of each device (biology, physics, chemistry, etc.).

Derivado del hecho de ser fabricado de una sola pieza se eliminan las uniones encoladas de las actuales. Estas uniones facilitan la adherencia de partículas a las mismas, subestimando la concentración de partículas en las muestras de agua, además de liberar sustancias químicas provenientes de los adhesivos. Derived from the fact of being manufactured in one piece, the glued joints of the current ones are eliminated. These joints facilitate the adhesion of particles to them, underestimating the concentration of particles in the water samples, in addition to releasing chemical substances from the adhesives.
