According to Figure 1, the present invention can avoi different embodiments.
L'un de ces modes consiste à utiliser comme station central 5 une embarcation. L'autre mode de réalisation, présenté sur cette figure consiste à utiliser un dispositif mobile, que ce soit un véhicul ou une remorque.One of these modes consists in using a boat as the central station 5. The other embodiment, presented in this figure, consists in using a mobile device, whether it is a vehicle or a trailer.
Il est bien évident que 1'invention pourrait tout aussi bie utiliser comme station centrale 5 une station fixe placée sur un berge et composée comme l'embarcation d'un tambour d'enroulemen 12 qui peut être actionné par un motoréducteur 24.It is obvious that the invention could equally well use as a central station 5 a fixed station placed on a bank and composed like the boat of a winding drum 12 which can be actuated by a geared motor 24.
Ce tambour d'enroulement 12 permet l'enroulement d'un tuya souple 4 ainsi que d'un tube souple 11, dont les fonctions seron précisées dans les figures qui suivent. Le tuyau souple 4 et le tube souple 11 sont reliés à une têt flottante 3 qui peut se déplacer sur 1'eau 2.This winding drum 12 allows the winding of a flexible tube 4 as well as a flexible tube 11, the functions of which will be specified in the figures which follow. The flexible hose 4 and the flexible tube 11 are connected to a floating head 3 which can move over water 2.
L'autre mode de réalisation placé sur la berge utilis également les mêmes moyens, c'est-à-dire le tuyau souple 4, l tube souple 11 et la tête flottante 3. Une grande flèche FI ou F2, présente devant chaque têt flottante 3, permet de comprendre dès à présent que les tête flottantes 3 peuvent être dirigées de sorte qu'elles vont pouvoi circonscrire une nappe polluée 1, présente à la surface de l'ea 2. La figure 2 précise plus avant la structure de la têt flottante 3.The other embodiment placed on the bank also uses the same means, that is to say the flexible pipe 4, the flexible tube 11 and the floating head 3. A large arrow FI or F2, present in front of each floating head 3, makes it possible to understand now that the floating heads 3 can be directed so that they can circumscribe a polluted tablecloth 1, present on the surface of the water 2. FIG. 2 specifies the structure of the head further floating 3.
Celle-ci est essentiellement composée de deux élément principaux quant à leur taille, tout d'abord le moyen d flottaison 16, ensuite le châssis 25. Le moyen de flottaison 16 est réalisé en toute matièr permettant d'éviter que le châssis 25 sous-jacent ne coule.This is essentially composed of two main elements as to their size, first of all the flotation means 16, then the chassis 25. The flotation means 16 is made of any material making it possible to prevent the chassis 25 from under- jacent does not flow.
Ce moyen de flottaison 16 peut tout aussi bien être réalis par exemple en polystyrène ou par une bouée remplie d'air.This flotation means 16 can just as easily be made, for example, of polystyrene or by a buoy filled with air.
Ce premier élément, au demeurant très simple, est form d'ergots mâles de fixation 19 présents sur sa face inférieure.This first element, moreover very simple, is formed by male fixing lugs 19 present on its underside.
Ceux-ci coopèrent avec les ergots femelles de fixation 20 présents sur le deuxième élément de la tête flottante 3, c'est-à dire le châssis 25.These cooperate with the female fixing lugs 20 present on the second element of the floating head 3, that is to say the chassis 25.
L'ensemble de ces ergots 19 et 20 permet la fixation du moye de flottaison 16 au châssis 25.All of these pins 19 and 20 allow the hub to be fixed flotation 16 to chassis 25.
Le châssis 25, pour sa part, reçoit une extrémité du tuya souple 4.The chassis 25, for its part, receives one end of the flexible pipe 4.
Celui-ci se prolonge sur toute la longueur du châssis 25. A l'intérieur du châssis 25, le moyen de déplacement e d'orientation de la tête flottante 3 est précisé.This extends over the entire length of the chassis 25. Inside the chassis 25, the means of displacement and orientation of the floating head 3 is specified.
Ce moyen est essentiellement formé par un injecteur 18 d fluide qui sert de moyen de propulsion, ledit injecteur 1 débouchant dans un venturi 17 qui se prolonge sous forme d'un tuyère 8.This means is essentially formed by an injector 18 d fluid which serves as a means of propulsion, said injector 1 opening into a venturi 17 which is extended in the form of a nozzle 8.
Le venturi 17 et la tuyère 8 sont orientables selon un ax 26.The venturi 17 and the nozzle 8 are orientable along an axis 26.
Selon la figure 3, la tête flottante 3 est vue en coupe.According to Figure 3, the floating head 3 is seen in section.
L'élément supérieur est formé du moyen de flottaison 16 muni en partie basse d'ergots mâles de fixation 19.The upper element is formed by the flotation means 16 provided at the bottom with male fixing lugs 19.
L'élément inférieur est formé par le châssis 25. Il possède, en position haute, les ergots femelles de fixation 2 correspondant aux ergots 19 du moyen de flottaison 16.The lower element is formed by the chassis 25. It has, in the high position, the female fixing lugs 2 corresponding to the lugs 19 of the flotation means 16.
Surmontant le châssis 25 et représenté en tirets pointillés discontinus, le tuyau souple 4 possède un logement 27 l'intérieur du moyen de flottaison 16.Overcoming the frame 25 and shown in broken dotted lines, the flexible pipe 4 has a housing 27 inside the flotation means 16.
Le châssis 25, vu en coupe, permet de distinguer trois canau permettant le passage du fluide de propulsion.The frame 25, seen in section, makes it possible to distinguish three channels allowing the passage of the propulsion fluid.
Le canal central est constitué par la tuyère orientable elle-même.The central channel is formed by the orientable nozzle itself.
Les autres canaux sont constitués par les conduits latérau 21 du fluide.The other channels are formed by the lateral conduits 21 of the fluid.
La figure 4 précise un élément essentiel de la présent invention. II s'agit du tuyau souple 4 qui est, dans l'exemple, présent lesté, ce qui lui permet de couler sous la surface de l'eau.Figure 4 specifies an essential element of the present invention. It is the flexible pipe 4 which is, in the example, present ballasted, which allows it to flow under the surface of the water.
Surmontant ledit tuyau 4, un tube souple 11 est présent.Overcoming said pipe 4, a flexible tube 11 is present.
Celui-ci a pour fonction de permettre la flottaison du tuya souple lesté 4. Le tube 11 n'a pas d'autre fonction, il ne renferme donc qu de l'air ou tout autre moyen permettant la flottaison.The function of the latter is to allow the floating of the ballasted flexible tube 4. The tube 11 has no other function, it therefore only contains air or any other means allowing the flotation.
De plus, il est fermé et ne peut subir aucune influence part celle due à la souplesse desdits tubes 11 et tuyaux 4.In addition, it is closed and cannot undergo any influence except that due to the flexibility of said tubes 11 and pipes 4.
Le tuyau 4, pour sa part, permet l'amenée des moyens d commande hydraulique 22, dont la fonction sera précisée ddns le figures qui suivent.The pipe 4, for its part, allows the supply of the means of hydraulic control 22, the function of which will be specified in the figures which follow.
Les moyens de commande hydraulique 22 pourraient néanmoin être véhiculés par le tube souple 4. Lorsque le tuyau 4 et le tube 11 sont placés dans l'eau 2, le tuyau souple 4, qui est lesté, a tendance à être en dessous d la surface de l'eau 2, alors que le tube souple 11 possèd toujours une partie émergée.The hydraulic control means 22 could nevertheless be conveyed by the flexible tube 4. When the hose 4 and the tube 11 are placed in the water 2, the flexible hose 4, which is ballasted, tends to be below the surface water 2, while the flexible tube 11 still has an emerged part.
Les deux tuyau 4 et tube 11, étant superposés et étant relié l'un à l'autre, grâce à une jupe souple et hermétique 28, von pouvoir circonscrire et stocker une nappe polluée 1 épaisse.The two pipes 4 and tube 11, being superimposed and being connected to each other, by means of a flexible and hermetic skirt 28, von being able to circumscribe and store a thick polluted tablecloth 1.
La figure 5 montre que le tuyau souple 4 peut posséder de trous 14 placés du côté de la nappe polluée 1, afin de permettr la flottation de microdéchets présents à 1'intérieur de la napp polluée 1, le fluide 10 contenu dans ledit tuyau souple 4 es alors éjecté selon les flèches F3.FIG. 5 shows that the flexible pipe 4 can have holes 14 placed on the side of the polluted sheet 1, in order to allow the flotation of micro-waste present inside the polluted sheet 1, the fluid 10 contained in said flexible pipe 4 are then ejected according to the arrows F3.
La jupe souple hermétique 28 est hermétique du côté de l nappe polluée 1, alors qu'elle possède des trous 31 de l'autr côté pour permettre son nettoyage et/ou son vidage. Selon le mode d'utilisation des tuyaux souples 4 et des tube 11 de la figure 1, lesdits tuyaux 4 et tubes 11 on obligatoirement une armature suffisamment solide pour permettr leur manipulation c'est-à-dire qu'ils vont permettre le charriag d'une nappe 1 épaisse et/ou de grande surface. Ce charriage pourra être le fait soit d'un enroulement su le tambour d'enroulement 12 actionné par le motoréduteur 24, soi par le déplacement de la station centrale 5 qui devra être mobil de façon terrestre ou sur l'eau.The hermetic flexible skirt 28 is hermetic on the side of the polluted tablecloth 1, while it has holes 31 on the other side to allow it to be cleaned and / or emptied. According to the mode of use of the flexible pipes 4 and the tubes 11 of FIG. 1, the said pipes 4 and tubes 11 necessarily have a sufficiently strong reinforcement to allow their manipulation, that is to say that they will allow the carriage of '' a thick and / or large area tablecloth 1. This thrusting can be the fact either of a winding on the winding drum 12 actuated by the geared motor 24, or by the displacement of the central station 5 which will have to be mobile on land or on water.
Le venturi 17 est suffisamment large pour permettr l'orientation de l'ensemble tuyère 8-venturi 17 sans que l'arrivé 18 du fluide 10 ne soit gênée.The venturi 17 is wide enough to allow the orientation of the nozzle 8-venturi assembly 17 without the inlet 18 of the fluid 10 being obstructed.
Dans la partie arrière du châssis 25 de la tête flottante 3, sont présentes trois ouvertures.In the rear part of the chassis 25 of the floating head 3, there are three openings.
La première ouverture est centrale et permet la propulsio en ligne droite.The first opening is central and allows propulsion in a straight line.
Les deux autres sont latérales et permettent le déplacemen latéral de la tête flottante 3.The other two are lateral and allow lateral movement of the floating head 3.
Dans ce dernier cas, le fluide 10 parcourra un des conduit latéraux 21. Selon les figures 6, 7 et 8, la tuyère orientable 8 s compose d'un hydro-éjecteur.In the latter case, the fluid 10 will pass through one of the lateral conduits 21. According to Figures 6, 7 and 8, the steerable nozzle 8 s consists of a hydro-ejector.
L'hydro-éjecteur est formé d'une part par un injecteur 18 d fluide 10 qui injecte ledit fluide 10 dans un venturi 17. L'injecteur 18 est fixe par rapport au châssis 25, où il es implanté.The hydro-ejector is formed on the one hand by an injector 18 d fluid 10 which injects said fluid 10 into a venturi 17. The injector 18 is fixed relative to the frame 25, where it is located.
Le venturi 17 est mobile selon un axe d'orientation 26 pa rapport au châssis 25, cette mobilité est le fait des moyens d manoeuvre 9 tels que des vérins, au nombre de deux, répartis d part et d'autre de la tuyère 8.The venturi 17 is movable along an orientation axis 26 pa relative to the chassis 25, this mobility is due to the operating means 9 such as jacks, two in number, distributed on either side of the nozzle 8.
Le venturi 17 peut avoir deux positions extrêmes.The venturi 17 can have two extreme positions.
Soit, comme cela est représenté à la figure 7, le fluide 10 est éjecté selon les flèches F4, dans le venturi 17 placé dans l'axe longitudinal formé par l'injecteur 18 et le venturi 17 vers l'extérieur de la tête flottante 3, de sorte que la tête flottantOr, as shown in FIG. 7, the fluid 10 is ejected according to the arrows F4, into the venturi 17 placed in the longitudinal axis formed by the injector 18 and the venturi 17 towards the outside of the floating head 3 , so that the floating head
3 va s'éloigner de la station centrale 5 en ligne droite selon F5.3 will move away from central station 5 in a straight line along F5.
Soit, comme cela est représenté à la figure 8, le fluide 10 est éjecté, selon les flèches F7, dans le venturi 17, qui est orienté grâce aux vérins 9 dont le mouvement est représenté selon les flèches F6, de sorte que le fluide 10 débouche dans un des conduits latéraux 21 du châssis 25, dont les orifices d'éjectio sont situés latéralement, de sorte que la tête flottante 3 v décrire un arc de cercle, selon F8.Or, as shown in FIG. 8, the fluid 10 is ejected, according to the arrows F7, into the venturi 17, which is oriented by means of the jacks 9 whose movement is represented according to the arrows F6, so that the fluid 10 opens into one of the lateral conduits 21 of the chassis 25, the ejection orifices of which are located laterally, so that the floating head 3 v describes an arc of a circle, according to F8.
L'actionnement des vérins 9 est le fait des moyens d commande hydraulique 22 qui sont présents à 1'intérieur du tuyau souple 4, vu précédemment.The actuation of the jacks 9 is the result of the hydraulic control means 22 which are present inside the flexible pipe 4, seen previously.
La figure 9 montre un autre mode de réalisation du dispositif selon l'invention.Figure 9 shows another embodiment of the device according to the invention.
Ce dispositif est essentiellement composé d'une têt flottante 30 dont la partie supérieure est formée par un moyen de flottaison 29.This device is essentially composed of a floating head 30, the upper part of which is formed by a flotation means 29.
Ladite tête 30 est reliée à une station centrale 5, pa 1'intermédiaire de deux tuyaux souples 4.Said head 30 is connected to a central station 5, by means of two flexible pipes 4.
Ces deux tuyaux souples 4 sont enroulés sur un tambou d'enroulement 12.These two flexible pipes 4 are wound on a winding drum 12.
Chaque tuyau souple 4 est alimenté en fluide pa l'intermédiaire d'un ensemble de conduits étanches, dans lesquels sont insérés un robinet de réglage du débit 13 de la pression du fluide, ainsi qu'un moyen de répartition 15 du fluide envoyé dans 1*un ou 1'autre des deux tuyaux souples 4.Each flexible pipe 4 is supplied with fluid pa by means of a set of sealed conduits, into which are inserted a valve for adjusting the flow rate 13 of the fluid pressure, as well as a means 15 for distributing the fluid sent into 1 * one or the other of the two flexible pipes 4.
Selon la figure 10, la tête flottante 30 est vue de profil. Ladite tête flottante 30 est composée du moyen de flottaisonAccording to FIG. 10, the floating head 30 is seen in profile. Said floating head 30 is composed of the flotation means
29, sous lequel prend place un tuyau 4 qui masque le second tuyau souple 4.29, under which takes place a pipe 4 which masks the second flexible pipe 4.
Le tuyau souple 4 visible aboutit à la tuyère latérale bâbord 7.The visible flexible pipe 4 ends at the port side nozzle 7.
Cette tête flottante 30 comporte également une quille 23 permettant de stabiliser sa position lorsqu'elle est en flottaison dans l'eau 2.This floating head 30 also includes a keel 23 making it possible to stabilize its position when it is floating in water 2.
La figure 11 présente une vue de dessous de la tête flottanteFigure 11 shows a bottom view of the floating head
30, dépourvue de sa quille 23.30, devoid of its keel 23.
Chacun des deux tuyaux souples 4 aboutit à une tuyère latérale, l'une bâbord 7, l'autre tribord 6. La figure 12 représente l'ensemble des éléments vus dans les trois figures précédentes.Each of the two flexible pipes 4 leads to a side nozzle, one on port 7, the other on starboard 6. FIG. 12 represents all of the elements seen in the three preceding figures.
La tête flottante 30 est composée du moyen de flottaison 29 et des tuyères latérales bâbord 7 et tribord 6, sous-jacentes.The floating head 30 is composed of the buoyancy means 29 and the port side nozzles 7 and starboard 6, underlying them.
Celles-ci se prolongent par deux tuyaux 4 qui vont s'enrouler au niveau de la station centrale 5, sur un tambour d'enroulement 12 mû en rotation par l'intermédiaire d'un motoréducteur 24.These are extended by two pipes 4 which will wind up at the level of the central station 5, on a winding drum 12 driven in rotation by means of a geared motor 24.
Chaque tuyau souple 4 est alimenté en fluide par l'intermédiaire de conduits dans lesquels sont insérés d'une part, un robinet de réglage, du débit 13, d'autre part un moyen de répartition 15.Each flexible pipe 4 is supplied with fluid by means of conduits into which are inserted on the one hand, a regulating valve, of the flow rate 13, and on the other hand a distribution means 15.
Enfin, la figure 13 représente un autre mode de réalisation de la tête flottante 3, dans laquelle le tuyau 4 aboutit à deux tuyères latérales.Finally, Figure 13 shows another embodiment of the floating head 3, in which the pipe 4 leads to two lateral nozzles.
L'orientation qui sera donnée au fluide 10 est due à des vérins d'actionnement 32 de déflecteurs 33.The orientation which will be given to the fluid 10 is due to actuating cylinders 32 of deflectors 33.
Sans sortir du domaine de l'invention, le nombre de tuyères latérale bâbord et tribord peut être multiple.Without departing from the scope of the invention, the number of side port and starboard nozzles may be multiple.
De la même façon, le nombre de tuyaux 4 par tête de flottaison peut être d'un ou plus, le mode préférentiel étant d'utiliser une tuyère orientable 8 pour un tuyau souple 4.Likewise, the number of pipes 4 per floatation head can be one or more, the preferred mode being to use an adjustable nozzle 8 for a flexible pipe 4.
Néanmoins, un dispositif utilisant deux tuyères latérales, ne peut être alimenté en fluide 10 par un seul tuyau souple 4, le répartiteur agissant par 1'intermédiaire de moyens de commande hydraulique sur un dispositif présent au niveau de la tête flottante, quelle que soit la tête flottante 3 ou 30 utilisé.However, a device using two lateral nozzles cannot be supplied with fluid 10 by a single flexible pipe 4, the distributor acting by means of hydraulic control means on a device present at the head. floating, regardless of the floating head 3 or 30 used.
Celle-ci peut être munie, au niveau de sa proue, d'un moye d'accrochage lui permettant, lorsqu'elle rencontre un moye d'accrochage complémentaire, de se fixer à celui-ci. Le moyen d'accrochage complémentaire peut être attaché à un autre tête flottante, ou à une autre station centrale, ou à un berge, ou encore à la même station centrale 5 dont dépend la têt flottante 3 ou 30, de sorte qu'il sera possible de circonscrir et de stocker une nappe polluée 1. Après avoir circonscrit et stocké cette nappe, il ser possible de l'épaissir soit en tirant sur l'ensemble des tuyau 4 qui permettent de circonscrire ladite nappe polluée 1 soit e enroulant le ou les tuyaux souples 4 sur leur tambour d'enrouleu 12 respectif. Les tuyaux souples 4 font alors office de barrage flottant.This can be provided, at the level of its prow, with a hooking hub allowing it, when it encounters a complementary hooking hub, to attach to it. The additional attachment means can be attached to another floating head, or to another central station, or to a bank, or even to the same central station 5 on which the floating head 3 or 30 depends, so that it will be possible to circumscribe and store a polluted tablecloth 1. After having circumscribed and stored this tablecloth, it will be possible to thicken it either by pulling on the set of pipes 4 which make it possible to circumscribe said polluted tablecloth 1 or by winding the flexible pipes 4 on their respective reel drum 12. The flexible pipes 4 then act as a floating barrier.
Le traitement de cette nappe polluée 1, ou son évacuation, pourra être le fait de la station centrale 5, que celle-ci soit une embarcation ou un dispositif se trouvant sur la berge, ou pourra encore être le fait d'un moyen complémentaire tel qu'une suceuse ou une usine de retraitement. The treatment of this polluted tablecloth 1, or its evacuation, can be done by the central station 5, whether this is a boat or a device located on the bank, or can also be done by an additional means such than a suction machine or a reprocessing plant.
