Deposito obturador de conductos, y dispositivo de sellado que contiene dicho deposito OBJETO DE LA INVENCIONDuct sealing tank, and sealing device containing said deposit OBJECT OF THE INVENTION
La presente invention pertenece al campo de los sistemas de canalizaciones y distribution de lmeas electricas, y mas concretamente a dispositivos de obturation y/o sellado de tuberias y conductos.The present invention belongs to the field of channeling and distribution systems of electric lines, and more specifically to sealing and / or sealing devices for pipes and ducts.
El objeto de la invencion es un deposito obturador, asi como un dispositivo de sellado que contiene dicho deposito, mediante los cuales se consigue incrementar eficazmente la protection de conductos y/o cables electricos alojados dentro de dichos conductos, al mismo tiempo que constituye una solution segura, duradera en el tiempo y auto-regulable en presion, ademas de suponer un comodo y sencillo acoplamiento del mismo en todo tipo de ubicaciones finales, ya sea en suelo, techo o pared.The object of the invention is a sealing tank, as well as a sealing device containing said tank, by means of which it is possible to effectively increase the protection of conduits and / or electrical cables housed within said conduits, while constituting a solution. safe, durable in time and self-adjustable in pressure, in addition to assuming a comfortable and simple coupling of it in all types of final locations, whether on floor, ceiling or wall.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
Actualmente son conocidos en el estado de la tecnica diferentes dispositivos para el sellado y obturacion de conductos, tanto para conductos de canalization de aguas subterraneas, como para conductos de redes de distribucion electrica.Currently, different devices for sealing and sealing ducts are known in the state of the art, both for underground water canalization conduits, and for electrical distribution network conduits.
Estos dispositivos de sellado, destinados a instalarse en el interior de los conductos, arquetas o similares, tienen como cometido principal evitar escapes de Kquido, impedir la entrada de polvo y suciedad, asi como proporcionar proteccion al conducto y/o al cableado interno frente a posibles restos de piedras o elementos externos punzantes que podrian danar y afectar a los mismos, pudiendose producir cortes electricos, contaminaciones del agua de consumo publico, obstrucciones indeseadas de los conductos, etc.These sealing devices, intended to be installed inside the ducts, caskets or similar, have the main task of preventing leaks of Kido, preventing the entry of dust and dirt, as well as providing protection to the conduit and / or internal wiring against possible remains of stones or sharp external elements that could damage and affect them, being able to produce electrical cuts, contamination of the water of public consumption, unwanted obstructions of the conduits, etc.
A este respecto, cabe citar por ejemplo la solicitud de patente espanola ES2436854 A1, la cual describe un dispositivo de sellado de conductos que incorpora un deposito dentro del cual se encuentra alojado aire a presion, un pulsador que permite liberar dicho aire a presion, y una bolsa; de tal manera que mediante el accionamiento del pulsador se provocaIn this regard, it is worth mentioning, for example, the Spanish patent application ES2436854 A1, which describes a duct sealing device that incorporates a reservoir within which air under pressure is housed, a push button that allows said air to be released under pressure, and a bag; in such a way that the actuation of the button causes

la liberation del gas comprimido existente dentro de la bolsa, lo cual provoca el hinchado de la bolsa hasta conseguir la obturation del conducto. Otro ejemplo se puede apreciar en la patente ES2420786 B1, donde se describe otro deposito de gas comprimido que cuenta con medios de rotura para el inflado de compartimentos estancos. Asi, se ha detectado que estos dispositivos de obturacion presentan varios inconvenientes, entre los que destacan:the liberation of the existing compressed gas inside the bag, which causes the bag to swell until the duct is blocked. Another example can be seen in the patent ES2420786 B1, where another reservoir of compressed gas is described which has means of rupture for the inflation of sealed compartments. Thus, it has been detected that these shutter devices have several drawbacks, among which are:
- Los depositos o botellas actuales estan basados en envases metalicos que almacenan un gas comprimido (en caso de tratarse de aire comprimido, este suele estar en torno a 250 bares de presion, mientras que si se trata de dioxido de carbono licuado, su presion interna ronda los 70 bares aproximadamente). Por tanto, estos dispositivos conllevan la manipulation de gases a presiones muy elevadas, con los peligros que ello genera, bien por escapes accidentales del gas, o por explosiones fortuitas de los depositos.- The current tanks or bottles are based on metal containers that store a compressed gas (in case of compressed air, this is usually around 250 bars of pressure, while in the case of liquefied carbon dioxide, its internal pressure around 70 bars approximately). Therefore, these devices involve the manipulation of gases at very high pressures, with the dangers that this generates, either by accidental gas leaks, or by accidental explosions of the deposits.
- Ademas, el inflado o hinchado de las bolsas se lleva a cabo mediante un disparo subito, repentino y violento de salida del gas comprimido, lo cual origina diferentes peligros, tanto para la integridad de los conductos donde estan instaladas, como para la propia bolsa, que puede rajarse o perforarse. Para evitar estos peligros, existen dispositivos que requieren la instalacion adicional de una valvula, lo cual redunda en una mayor complejidad y un mayor coste economico de fabrication y ensamblaje de la valvula.- In addition, the inflation or swelling of the bags is carried out by means of a sudden, sudden and violent firing of the compressed gas, which creates different hazards, both for the integrity of the ducts where they are installed, and for the bag itself , which can crack or pierce. To avoid these dangers, there are devices that require the additional installation of a valve, which results in greater complexity and a greater economic cost of manufacturing and assembling the valve.
- Algunos dispositivos de obturacion requieren ademas de un “pulsador” para la liberacion del gas, el cual esta formado a su vez por multitud de piezas (gatillo, pasador, cabeza de conexion, valvula, etc.) aumentando la complejidad estructural del conjunto y las probabilidades a fallos y errores de funcionamiento, ademas de los costes totales.- Some sealing devices also require a "push button" for the release of gas, which in turn consists of many parts (trigger, pin, connection head, valve, etc.) increasing the structural complexity of the assembly and the probabilities to failures and errors of operation, in addition to the total costs.
- Con el paso del tiempo, los actuales depositos de gas comprimido pierden eficacia debido a la leve pero constante perdida de presion de su gas interno almacenado, reduciendose por tanto su utilidad y en consecuencia debiendo ser dichos depositos de gas sustituidos.- With the passage of time, the current deposits of compressed gas lose efficiency due to the slight but constant loss of pressure of their stored internal gas, thus reducing its usefulness and consequently these gas tanks must be substituted.
- La instalacion de estos depositos o botellas de gas, consistentes en robustos envases de metal, provoca serias dificultades a la hora de acoplar y ubicar los dispositivos- The installation of these gas tanks or bottles, consisting of robust metal containers, causes serious difficulties when attaching and locating the devices

de obturation dentro de los conductos, existiendo limitaciones notables de volumen de espacio en funcion del lugar donde vaya a estar ubicado el dispositivo (suelo, techo o pared), y en consecuencia haciendo mas complejo y tedioso el proceso de instalacion.of obturation within the ducts, there are notable limitations on the volume of space depending on where the device will be located (floor, ceiling or wall), and consequently making the installation process more complex and tedious.
- Por ultimo, otro problema radica en que los dispositivos obturadores actuales son dispositivos de carga de presion interna fija, constituyendo un unico modelo estandar, “teoricamente” valido para conductos o cables de todos los diametros, y que es independiente del diametro del cable a obturar. Debido a que se trata de dispositivos de carga fija, sin medios de regulation de presion, se producen sobrepresiones en el conducto, llegando incluso a producirse el estallido o reventado de su bolsa por presion elevada. Otro efecto negativo asociado a este hecho es la atenuacion de los cables de fibra optica, que al sufrir una presion excesiva sobre los mismos afectan al paso adecuado de los haces de luz, y por tanto afectando y limitando la transmision de datos.- Finally, another problem is that the current shutter devices are fixed internal pressure charging devices, constituting a single standard model, "theoretically" valid for conduits or cables of all diameters, and that is independent of the cable diameter shut Because they are fixed load devices, without pressure regulation means, overpressures occur in the duct, even bursting or bursting of your bag due to high pressure. Another negative effect associated with this fact is the attenuation of the fiber optic cables, which when suffering excessive pressure on them affect the proper passage of the light beams, and therefore affecting and limiting the transmission of data.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
Mediante la presente invention se solucionan los inconvenientes anteriormente citados proporcionando un deposito obturador de conductos, asi como un dispositivo de sellado que contiene dicho deposito, los cuales permiten incrementar la protection de conductos, tanto de canalizaciones de aguas como de redes electricas, y en especial conductos de cables de fibra optica, al mismo tiempo que constituye una solution eficaz y segura, eliminando cualquier posibilidad de explosiones fortuitas, y suponiendo un comodo y sencillo acoplamiento del mismo. El dispositivo de sellado de la invencion esta ademas adaptado para propulsar a presion el Kquido contenido en el interior del deposito obturador contra un compuesto quimico carbonatado, facilitando la instalacion y el accionamiento del dispositivo de sellado en cualquier position u orientation en que se encuentre el cable y/o conducto a obturar, ya sea en suelos, techos o paredes, como se explicara mas adelante.By means of the present invention, the aforementioned drawbacks are solved by providing a duct sealing tank, as well as a sealing device containing said reservoir, which allow to increase the protection of ducts, both of water pipes and electrical networks, and especially fiber optic cable ducts, at the same time that it constitutes an effective and safe solution, eliminating any chance of accidental explosions, and assuming a comfortable and simple coupling thereof. The sealing device of the invention is also adapted to propel the liquid contained inside the sealing tank against a carbonated chemical compound, facilitating the installation and operation of the sealing device in any position or orientation in which the cable is located. and / or duct to be sealed, either on floors, ceilings or walls, as will be explained later.
El deposito obturador de la invencion comprende un cuerpo hueco y alargado, caracterizado por que dicho cuerpo hueco es de material flexible y comprende a su vez al menos: un primer tramo y un segundo tramo que tiene un extremo proximal y un extremo distal; donde el primer tramo y el segundo tramo son huecos y estan alineados entre si segun un mismo eje axial imaginario; donde tanto el primer tramo y el segundo tramo delThe sealing tank of the invention comprises a hollow and elongated body, characterized in that said hollow body is made of flexible material and in turn comprises at least: a first section and a second section having a proximal end and a distal end; where the first section and the second section are hollow and are aligned with each other along the same imaginary axial axis; where both the first section and the second section of the

cuerpo hueco contienen un Kquido en su interior; y donde dicho cuerpo hueco de material flexible es facilmente deformable por aplicacion de una fuerza de presion sobre el mismo, para la liberation del Kquido contenido en cada una de sus tramos.hollow body contain a liquid inside; and where said hollow body of flexible material is easily deformable by applying a force of pressure on it, for the release of the liquid contained in each of its sections.
Preferentemente, se ha previsto que el cuerpo hueco del deposito pueda comprender adicionalmente un tercer tramo intermedio de section conica o inclinada, dispuesto entre el primer tramo y el segundo tramo, y donde ademas dicho tercer tramo intermedio es hueco y apto para contener un Kquido en su interior, y esta alineado segun el mismo eje axial que el primer y segundo tramo. Esta particularidad va a permitir favorecer la circulation del liquido contenido en el primer tramo hacia el segundo tramo del cuerpo hueco.Preferably, it is provided that the hollow body of the tank may additionally comprise a third intermediate section of conical or inclined section, disposed between the first section and the second section, and where also said third intermediate section is hollow and suitable for containing a liquid in its interior, and is aligned according to the same axial axis as the first and second section. This particularity will allow to favor the circulation of the liquid contained in the first section towards the second section of the hollow body.
Ademas, se ha contemplado la posibilidad de que el deposito obturador aqu descrito pueda comprender una membrana rompible, ubicada en el extremo distal del segundo tramo. No obstante, de acuerdo con otra posibilidad alternativa, se ha previsto que en lugar de una membrana, el deposito obturador incluya un tapon o caperuza desprendible e igualmente ubicado en el extremo distal del segundo tramo. Asi, tanto la membrana como el tapon permiten obtener una adecuada salida del liquido contenido en el cuerpo hueco, una vez alcanzado un determinado valor umbral de presion, como consecuencia de la deformation de la geometria del deposito obturador, siendo dicha deformation preferiblemente causada al estirar o tirar de una cinta de activation por parte del usuario como se explicara mas adelante, o directamente presionando manualmente sobre el mismo.In addition, the possibility has been contemplated that the sealing tank described herein may comprise a breakable membrane, located at the distal end of the second section. However, according to another alternative possibility, it is provided that instead of a membrane, the sealing tank includes a removable cap or cap and also located at the distal end of the second section. Thus, both the membrane and the plug make it possible to obtain an adequate outlet of the liquid contained in the hollow body, once a certain pressure threshold value has been reached, as a consequence of the deformation of the geometry of the sealing tank, said deformation being preferably caused by stretching or pull an activation tape by the user as explained below, or by directly pressing on it.
De acuerdo con otro objeto de la invention, se describe a continuation un dispositivo de sellado que contiene el deposito obturador descrito mas arriba. Mas concretamente, dicho dispositivo de sellado comprende: un deposito formado por un cuerpo hueco contenedor de un Kquido; un recipiente flexible externo, cerrado hermeticamente, en cuyo interior se encuentra alojado el cuerpo hueco, donde dicho recipiente flexible contiene a su vez un compuesto quimico carbonatado y un reactivo, exteriores al cuerpo hueco; donde el cuerpo hueco es de un material facilmente deformable por aplicacion de una fuerza de presion sobre el mismo, para la liberacion del Kquido contenido en su interior; y donde dicho Kquido es un Kquido seleccionado tal que su contacto con el compuesto quimico carbonatado y elAccording to another object of the invention, a sealing device containing the sealing tank described above is described below. More specifically, said sealing device comprises: a tank formed by a hollow container body of a liquid; an external, tightly sealed flexible container, inside which the hollow body is housed, wherein said flexible container in turn contains a carbonated chemical compound and a reagent, external to the hollow body; where the hollow body is of a material easily deformable by application of a force of pressure on it, for the release of the liquid contained inside; and where said liquid is a selected liquid such that its contact with the carbonated chemical compound and the

reactivo del recipiente flexible resulta en una reaction de efervescencia que produce un gas, y con ello el inflado del recipiente flexible.Flexible container reagent results in an effervescence reaction that produces a gas, and thereby inflation of the flexible container.
Preferentemente, el dispositivo de sellado esta sellado al vatio. Esta caracteristica permite que el compuesto qwmico carbonatado y el reactivo del recipiente flexible externo se encuentren ubicados en position fija y estable, en correspondencia con el extremo distal del segundo cuerpo, o en su caso, en el extremo distal del cuarto tramo.Preferably, the sealing device is sealed to the watt. This feature allows the carbonated chemical compound and the reagent of the external flexible container to be located in a fixed and stable position, in correspondence with the distal end of the second body, or where appropriate, at the distal end of the fourth section.
Preferentemente, el dispositivo de sellado dispone de al menos una cinta adhesiva de estanqueidad, situada en su superficie externa. Esta cinta adhesiva permite conseguir una optima obturation del conducto en cuestion, quedando firmemente pegado a las paredes internas del conducto, al mismo tiempo que se proporciona un maximo acoplamiento entre dicha cinta adhesiva y las paredes curvadas del conducto, evitando cualquier posible hueco o ranura por donde podrian escapar liquidos o insertarse polvos, piedras pequenas u otros cuerpos externos.Preferably, the sealing device has at least one sealing tape, located on its outer surface. This adhesive tape makes it possible to achieve optimum sealing of the duct in question, being firmly glued to the inner walls of the duct, while providing maximum coupling between said duct tape and the curved walls of the duct, avoiding any possible gap or groove by where liquids could escape or dust, small stones or other external bodies be inserted.
Asi, el dispositivo de sellado de la invention, destinado a instalarse en el interior de un conducto, permite conseguir una obturacion segura del conducto, pues el inflado del recipiente flexible externo es un inflado progresivo, no repentino, cuya presion aumenta lentamente a medida que el gas es generado en el interior del recipiente. De esta manera, se logran evitar los actuales depositos o envases metalicos de gas comprimido, que ademas de suponer un peligro por la elevada presion almacenada, hacen mas compleja la instalacion en el interior de un conducto.Thus, the sealing device of the invention, intended to be installed inside a conduit, allows a secure sealing of the conduit, since inflation of the external flexible container is a progressive inflation, not sudden, whose pressure increases slowly as The gas is generated inside the container. In this way, it is possible to avoid the current deposits or metal containers of compressed gas, which in addition to posing a danger due to the high stored pressure, make the installation inside a duct more complex.
Ademas, el dispositivo de sellado de la invencion ofrece una ventaja importante en cuanto a la auto-regulacion de la presion del gas generado, la cual es obtenida por el propio principio de funcionamiento de la invencion, basado en aplicacion de una fuerza de presion sobre los tramos del cuerpo hueco contenedores de Kquido, forzando la circulation del Kquido a traves de estos, hasta superar una presion tal que se produce la salida de Kquido, para su reaccion con el compuesto quimico carbonatado. Asi, conforme el gas va siendo generado y la presion dentro del recipiente flexible externo va aumentando, una vez alcanzado un determinado valor de presion, el gas excedente generado se queda en formaIn addition, the sealing device of the invention offers an important advantage in terms of the self-regulation of the generated gas pressure, which is obtained by the operating principle of the invention itself, based on the application of a pressure force on the sections of the hollow body of Kquido containers, forcing the circulation of the Kquido through them, until a pressure such that the exit of Kquido occurs, for its reaction with the carbonated chemical compound. Thus, as the gas is generated and the pressure inside the external flexible container increases, once a certain pressure value has been reached, the excess gas generated remains in shape.

de gas licuado en el propio Kquido. De esta manera se consigue mantener la presion constante dentro del dispositivo de sellado, evitando sobrepresiones en los conductos, as^ como evitando el efecto negativo de atenuacion en los cables, en concreto cables de fibra optica.of liquefied gas in Kquido itself. In this way it is possible to maintain the constant pressure inside the sealing device, avoiding overpressures in the conduits, as well as avoiding the negative effect of attenuation in the cables, specifically fiber optic cables.

mencion a las figuras arriba citadas, sin que ello limite o reduzca el ambito de protection de la presente invention.Mention the aforementioned figures, without limiting or reducing the scope of protection of the present invention.
De acuerdo con una primera realization preferente del deposito obturador de conductos, mostrado en las figuras 1,2 y 3, dicho deposito obturador comprende un cuerpo hueco (1) y alargado, de material flexible que comprende a su vez: un primer tramo (10); un segundo tramo (20) que tiene un extremo proximal (21) y un extremo distal (22); un tercer tramo intermedio (30) de section conica o inclinada, dispuesto entre el primer tramo (10) y el segundo tramo (20); y un cuarto tramo (40) unido al extremo distal (22) del segundo tramo (20) a traves de un quinto tramo intermedio (50) de seccion conica o inclinada.According to a first preferred embodiment of the duct sealing tank, shown in Figures 1,2 and 3, said sealing tank comprises a hollow (1) and elongated body, of flexible material which in turn comprises: a first section (10 ); a second section (20) having a proximal end (21) and a distal end (22); a third intermediate section (30) of conical or inclined section, arranged between the first section (10) and the second section (20); and a fourth section (40) attached to the distal end (22) of the second section (20) through a fifth intermediate section (50) of conical or inclined section.
Ademas, en la figura 2 se puede apreciar que el deposito obturador comprende adicionalmente una membrana (60) rompible, ubicada en este ejemplo en el extremo distal (41) del cuarto tramo (40), y a traves de la cual se produce la salida de liquido contenido en el cuerpo hueco (1) una vez alcanzado un determinado valor de presion ejercido sobre el mismo como consecuencia de la deformation del cuerpo hueco (1) flexible.Furthermore, in Figure 2 it can be seen that the sealing tank additionally comprises a breakable membrane (60), located in this example at the distal end (41) of the fourth section (40), and through which the exit of liquid contained in the hollow body (1) once a certain pressure value exerted on it has been reached as a result of the deformation of the flexible hollow body (1).
No obstante, en lugar de la membrana (60), se ha previsto la incorporation de un tapon (70) o caperuza desprendible, igualmente ubicado en el ejemplo de la figura 2 en el extremo distal (41) del cuarto tramo (40), y adaptado para permitir la salida de liquido al aplicar una fuerza de presion sobre el cuerpo hueco (1) flexible, deformando su geometria.However, instead of the membrane (60), the incorporation of a removable cap (70) or cap is provided, also located in the example of Figure 2 at the distal end (41) of the fourth section (40), and adapted to allow the exit of liquid when applying a force of pressure on the hollow body (1) flexible, deforming its geometry.
En este punto conviene aclarar que, aunque en las figuras 3 y 4 aparecen representados simultaneamente tanto la membrana (60) como el tapon (70), estos elementos son alternativos, esto es, el deposito obturador de la invencion trabaja de forma optima con uno solo de dichos elementos, membrana o tapon, teniendo ambos la misma funcion de permitir la salida de liquido una vez alcanzado cierto nivel de presion ejercida por el usuario sobre el cuerpo hueco (1) flexible.At this point it should be clarified that, although both the membrane (60) and the plug (70) are represented simultaneously in figures 3 and 4, these elements are alternative, that is, the sealing tank of the invention works optimally with one only of said elements, membrane or plug, both having the same function of allowing the liquid to exit once a certain level of pressure exerted by the user on the flexible hollow body (1) has been reached.

Tal y como se observa en la figura 1, los tramos (10, 20, 30, 40 50) son huecos y estan alineados entre s^ segun un mismo eje axial (E) imaginario, conteniendo todos ellos un mismo Kquido en su interior, siendo en el presente ejemplo agua, aunque tambien podria ser vinagre. Mas concretamente, es importante senalar que el cuerpo hueco (1) esta fabricado en un material flexible, facilmente deformable por aplicacion de una fuerza de presion sobre el mismo, con objeto de provocar la liberation del liquido contenido en cada una de los tramos (10, 20, 30, 40, 50) del cuerpo hueco (1). De esta manera, la mezcla entre el liquido, el compuesto qtimico carbonatado (C), y un reactivo cualquiera, tal como acido dtrico o acido tartarico, conocidos en la preparation de bebidas efervescentes como gaseosas, resulta en la production final de gas CO2.As can be seen in figure 1, the sections (10, 20, 30, 40 50) are hollow and are aligned with each other according to the same imaginary axial axis (E), all of them containing the same liquid inside, being in the present example water, although it could also be vinegar. More specifically, it is important to note that the hollow body (1) is made of a flexible material, easily deformable by applying a force of pressure on it, in order to cause the release of the liquid contained in each of the sections (10 , 20, 30, 40, 50) of the hollow body (1). In this way, the mixture between the liquid, the carbonated chemical compound (C), and any reagent, such as dric acid or tartaric acid, known in the preparation of effervescent beverages as gaseous, results in the final production of CO2 gas.
En relation al compuesto qtimico carbonatado (C), este puede ser carbonato de calcio o bicarbonato de sodio. Mas preferentemente, el compuesto qtimico carbonatado (C) se encuentra mezclado con un acido tartarico, favoreciendo asi la reaction de efervescencia y la consecuente produccion de gas.In relation to the chemical compound carbonated (C), this may be calcium carbonate or sodium bicarbonate. More preferably, the chemical carbonated compound (C) is mixed with a tartaric acid, thus favoring the effervescence reaction and the consequent gas production.
Tal y como se puede apreciar en la figura 2, el segundo tramo (20) tiene una longitud (L2) mayor respecto de la longitud (L1) del primer tramo (10), asi como una section (S2) menor respecto de la seccion (S1) del primer tramo (10), estando dichos tramos (10, 20) llenos de liquido al maximo de su capacidad. Esta variation de secciones entre los tramos primero y segundo (10, 20) provoca que al ejercer una fuerza de presion sobre el primer tramo (10) del cuerpo hueco (1), preferentemente mediante una cinta de activation (120) como se explicara mas adelante, o mediante presion dactilar, esto es, mediante los propios dedos del usuario, dicho primer tramo (10) de material flexible se deforma, provocando la circulation forzosa del liquido a traves del segundo tramo (20), y en consecuencia provocando la rotura de la membrana (60) o el desprendimiento del tapon (70), para la salida final de liquido contenido en el interior del cuerpo hueco (1) con mayor velocidad a traves de la zona de menor seccion (S2).As can be seen in Figure 2, the second section (20) has a length (L2) greater with respect to the length (L1) of the first section (10), as well as a section (S2) shorter with respect to the section (S1) of the first section (10), said sections (10, 20) being filled with liquid to the maximum of its capacity. This variation of sections between the first and second sections (10, 20) causes that when exerting a force of pressure on the first section (10) of the hollow body (1), preferably by means of an activation belt (120) as explained more forward, or by finger pressure, that is, by the user's own fingers, said first section (10) of flexible material is deformed, causing the forced circulation of the liquid through the second section (20), and consequently causing the breakage of the membrane (60) or the detachment of the plug (70), for the final exit of liquid contained inside the hollow body (1) with greater speed through the area of smaller section (S2).
Asi, en esta primera realization preferente del deposito obturador, se puede observar ademas que el tercer tramo intermedio (30) tiene un angulo de inclination (a1) inferior al angulo de inclinacion (a2) del quinto tramo intermedio (50), ver figura 2. EstaThus, in this first preferred embodiment of the sealing tank, it can also be observed that the third intermediate section (30) has an inclination angle (a1) lower than the inclination angle (a2) of the fifth intermediate section (50), see figure 2 .

particular caracteristica va a favorecer, aun mas si cabe, una circulation optima del Kquido desde su ubicacion en el primer tramo (10) hacia el segundo tramo (20) a traves de una suave pendiente del tercer tramo intermedio (30) o primer angulo de inclination (a1). Al mismo tiempo, ese aumento de section repentino o segundo angulo de inclinacion (a2) definido por el quinto tramo (50), el cual parte del extremo distal (22) del segundo tramo (20) hasta el cuarto tramo (40), va a permitir una salida de liquido con fuerza y presion suficientes como para provocar la rotura del la membrana (60) o el desprendimiento del tapon (70).particular characteristic will favor, even more if possible, an optimal circulation of the liquid from its location in the first section (10) to the second section (20) through a gentle slope of the third intermediate section (30) or first angle of inclination (a1). At the same time, that sudden section increase or second angle of inclination (a2) defined by the fifth section (50), which starts from the distal end (22) of the second section (20) to the fourth section (40), goes to allow an exit of liquid with sufficient force and pressure to cause the rupture of the membrane (60) or the detachment of the plug (70).
Respecto a la figura 4, en ella se puede apreciar una segunda realization preferente del deposito obturador, estado formado este unicamente por tres tramos (10, 20, 30), y por tanto, mas sencillo estructuralmente. En este caso, como se puede observar, la membrana (60) y el tapon (70) se encuentran ubicados en el extremo distal (22) del segundo tramo (20), y donde el unico cambio de seccion existente es el obtenido por el tercer tramo intermedio (30).With respect to Figure 4, it can be seen a second preferred embodiment of the sealing tank, which is formed only by three sections (10, 20, 30), and therefore, structurally simpler. In this case, as can be seen, the membrane (60) and the plug (70) are located at the distal end (22) of the second section (20), and where the only existing section change is that obtained by the third intermediate section (30).
De acuerdo con otro objeto de la invention, se describe un dispositivo de sellado (100), mostrado en las figuras 3, 4 y 5, que contiene los depositos obturadores arriba descritos, y donde dicho dispositivo de sellado (100) comprende: un deposito formado por un cuerpo hueco (1) contenedor de un liquido; y un recipiente flexible (110) externo, tal como una bolsa, cerrada hermeticamente, en cuyo interior se encuentra alojado el cuerpo hueco (1), donde dicho recipiente flexible (110) contiene a su vez un compuesto quimico carbonatado (C) y un reactivo, exteriores al cuerpo hueco (1),According to another object of the invention, a sealing device (100), shown in Figures 3, 4 and 5, is described, which contains the sealing tanks described above, and wherein said sealing device (100) comprises: a tank formed by a hollow body (1) container of a liquid; and an external flexible container (110), such as a hermetically sealed bag, inside which the hollow body (1) is housed, wherein said flexible container (110) in turn contains a carbonated chemical compound (C) and a reagent, external to the hollow body (1),
donde el cuerpo hueco (1) es de un material facilmente deformable por aplicacion de una fuerza de presion sobre el mismo, para la liberation del liquido contenido en su interior,where the hollow body (1) is of a material easily deformable by application of a force of pressure on it, for the release of the liquid contained therein,
y donde dicho liquido es un liquido seleccionado tal que su contacto con el compuesto quimico carbonatado (C) y el reactivo del recipiente flexible (110) resulta en una reaccion de efervescencia que produce un gas, y con ello el inflado del recipiente flexible (110).and where said liquid is a selected liquid such that its contact with the carbonated chemical compound (C) and the reagent of the flexible container (110) results in an effervescence reaction that produces a gas, and thereby the inflation of the flexible container (110 ).

As^ segun una primera realizacion posible, mostrada en la figura 3, el dispositivo de sellado (100) comprende ademas un recipiente secundario (130) ubicado dentro del recipiente flexible (110) externo, y adaptado para alojar en su interior el compuesto qdmico carbonatado (C), el reactivo y el extremo distal (22, 41) del segundo tramo (20), o en su caso, del cuarto tramo (40), todos ellos sellados al vado. De esta manera, se garantiza en todo momento la reaccion entre el liquido y el compuesto qdmico carbonatado (C), sin posibilidad de fallos o errores por ausencia de contacto entre ambos elementos.Thus, according to a first possible embodiment, shown in Figure 3, the sealing device (100) also comprises a secondary container (130) located inside the external flexible container (110), and adapted to accommodate inside the carbonated chemical compound (C), the reagent and the distal end (22, 41) of the second section (20), or where appropriate, of the fourth section (40), all sealed to the ford. In this way, the reaction between the liquid and the carbonated chemical compound (C) is guaranteed at all times, without the possibility of failures or errors due to lack of contact between both elements.
Por otro lado, segun una segunda realizacion posible del dispositivo de sellado (100) representada en la figura 4, siendo esta mas simple y estructuralmente mas sencilla que la primera, ya que no incorpora ningun recipiente secundario (130), el dispositivo de sellado (100) esta sellado al vado, de manera que el compuesto qdmico carbonatado (C) y el reactivo del recipiente flexible (110) externo se encuentran ubicados en posicion fija y estable, en correspondencia con el extremo distal (22) del segundo cuerpo (20), o en su caso, en el extremo distal (41) del cuarto tramo (40).On the other hand, according to a second possible embodiment of the sealing device (100) represented in Figure 4, this being simpler and structurally simpler than the first, since it does not incorporate any secondary container (130), the sealing device ( 100) is sealed to the ford, so that the carbonated chemical compound (C) and the reagent of the external flexible container (110) are located in a fixed and stable position, in correspondence with the distal end (22) of the second body (20 ), or where appropriate, at the distal end (41) of the fourth section (40).
Preferentemente, el recipiente flexible (110) es una bolsa formada por un conjunto de capas de diferentes materiales, en concreto: capa de aluminio, capa de poliamida y capa de poliuretano.Preferably, the flexible container (110) is a bag formed by a set of layers of different materials, namely: aluminum layer, polyamide layer and polyurethane layer.
Ademas, en el ejemplo de las figuras 3 y 4 se aprecia que la bolsa externa (110) comprende una cinta adhesiva (111) de estanqueidad, preferentemente de butilo, situada sobre su superficie externa central. Dicho material, butilo, constituye un material viscoso, blando y pegajoso, que proporciona una firme y segura adherencia del dispositivo de sellado (1) a las paredes internas del conducto (A) a obturar.Furthermore, in the example of figures 3 and 4 it can be seen that the outer bag (110) comprises an adhesive tape (111) of sealing, preferably of butyl, located on its central outer surface. Said material, butyl, constitutes a viscous, soft and sticky material, which provides a firm and safe adhesion of the sealing device (1) to the internal walls of the conduit (A) to be sealed.
Por otro lado, la bolsa externa (110) comprende ademas una cinta de activacion (120) unida a uno de los extremos de la bolsa externa (110). Esta cinta de activacion va a facilitar la deformacion de la geometria del cuerpo hueco (1) flexible, sin mas que estirar o tirar perpendicularmente de dicha cinta de activacion.On the other hand, the outer bag (110) further comprises an activation tape (120) attached to one of the ends of the outer bag (110). This activation tape will facilitate the deformation of the geometry of the flexible hollow body (1), without more than stretching or pulling perpendicularly of said activation tape.

En este punto, cabe indicar que el recipiente flexible (110) externo esta fabricado en un material flexible, tal como plastico, de modo que sea facilmente deformable y plegable, mientras que el recipiente secundario (130) arriba citado puede ser de naturaleza flexible o rigida, pero con capacidad de ser ambos recipientes introducidos dentro del conducto (A) a obturar, y/o enrollados alrededor de un cable electrico (B) circulante por el interior de dicho conducto (A), tal y como muestra la figura 5. Mas en particular, la bolsa externa (110) esta formada por un conjunto de capas de diferentes materiales, en concreto: capa de aluminio, capa de poliamida y capa de poliuretano, mediante las cuales se obtiene una optima resistencia y tenacidad de la bolsa externa (110), al mismo tiempo que permite un adecuado plegado de la misma para su insercion en el interior del conducto de que se trate.At this point, it should be noted that the external flexible container (110) is made of a flexible material, such as plastic, so that it is easily deformable and collapsible, while the aforementioned secondary container (130) can be flexible in nature or rigid, but capable of being both containers inserted into the conduit (A) to be sealed, and / or wrapped around an electric cable (B) circulating inside said conduit (A), as shown in Figure 5. More particularly, the outer bag (110) is formed by a set of layers of different materials, namely: aluminum layer, polyamide layer and polyurethane layer, through which optimum resistance and toughness of the external bag is obtained (110), while allowing an adequate folding thereof for insertion into the duct in question.
Ademas, y aunque no se ha representado en las figuras, se ha previsto que el recipiente secundario (130) pueda disponer de una pluralidad de micro-orificios en su superficie externa, tal que al producirse el gas dentro del recipiente secundario (130), dicho gas escapa a traves de los micro-orificios introduciendose en la bolsa externa (110). En este punto, es importante indicar que los micro-orificios seran preferentemente de un diametro tal, que permiten la salida del gas CO2 desde el recipiente secundario (130) hacia la bolsa externa (110), pero que al mismo tiempo no permita que el compuesto qdmico carbonatado (C) se reparta o se salga de dicho recipiente secundario (130), con lo cual podria quedar fuera de la reaccion, asegurando asi una presion homogenea en el dispositivo obturador.In addition, and although not shown in the figures, it is provided that the secondary vessel (130) may have a plurality of micro-holes in its outer surface, such that when the gas is produced within the secondary vessel (130), said gas escapes through the micro-holes entering the outer bag (110). At this point, it is important to indicate that the micro-holes will preferably be of such a diameter, that they allow CO2 gas to escape from the secondary container (130) to the outer bag (110), but at the same time do not allow the Carbonated chemical compound (C) is distributed or out of said secondary vessel (130), which could be left out of the reaction, thus ensuring a homogeneous pressure on the sealing device.
No obstante, otro modo posible para el paso del gas procedente del recipiente secundario (130) hacia la bolsa externa (110) consiste en que el extremo distal (22, 41) del segundo tramo (20), o en su caso del cuarto tramo (40), se encuentren alojados en el interior del recipiente secundario (130), estando todo el conjunto sellado al vado en el interior de la bolsa externa (110), de manera que las paredes interiores de esta ultima se comprimen sobre los elementos citados obturando las aperturas existentes, tal que debido al gas producido dentro de ella, el recipiente secundario (130) va liberando el gas progresivamente provocando el hinchado final de la bolsa externa (110).However, another possible way for the passage of gas from the secondary vessel (130) into the outer bag (110) is that the distal end (22, 41) of the second section (20), or where appropriate the fourth section (40), are housed inside the secondary container (130), the whole assembly being sealed to the ford inside the outer bag (110), so that the inner walls of the latter are compressed on the mentioned elements sealing the existing openings, such that due to the gas produced inside it, the secondary container (130) gradually releases the gas causing the final swelling of the outer bag (110).
En este punto, cabe indicar que se ha previsto la posibilidad de que exista una regulacion o control de la presion generada, de modo que una vez alcanzado un valor de presion determinado, el gas CO2 generado sobrante es almacenado en el agua, siendo entonces CO2 diluido, lo que permite mantener la presion constante sin que esta 5 siga aumentando, evitando as^ posibles estallidos o reventados de la bolsa externa (110). Esto hace posible una optima adaptacion del dispositivo obturador de la invencion a diferentes tamanos o dimensiones del conducto (A) o el cable (B) a obturar, como por ejemplo conductos desde 25mm. a 250 mm. y cables desde 7 mm. a 84 mm.At this point, it should be noted that the possibility of a regulation or control of the generated pressure is provided, so that once a certain pressure value has been reached, the excess generated CO2 gas is stored in the water, then CO2 diluted, which allows to maintain the constant pressure without increasing this, thus avoiding possible bursts or bursting of the external bag (110). This makes possible an optimal adaptation of the sealing device of the invention to different sizes or dimensions of the conduit (A) or the cable (B) to be sealed, such as for example conduits from 25mm. at 250 mm and cables from 7 mm. to 84 mm.
