Abstract

A vessel travels over a surface of a body of water or a waterway to collect waste on and/or close to the surface. A retainer that traps and retains the waste is activated by creating a water flow channel that is connected to a water inlet and a water outlet on the vessel. The retainer is on at least one trajectory of said channel. Waste is collected without using a specific pumping or gathering device.

Description

La présente invention concerne un bâtiment destiné à évoluer sur une surface d'un plan ou d'un cours d'eau, et à recueillir à son bord des déchets présents au voisinage de ladite surface.The present invention relates to a building intended to evolve on a surface of a plane or a watercourse, and to collect on board waste present in the vicinity of said surface.

De tels bâtiments sont couramment utilisés pour débarrasser des eaux portuaires de déchets flottants à leur surface, comme des objets flottants ou des nappes d'hydrocarbure.Such buildings are commonly used to remove floating waste from port waters, such as floating objects or oil slicks.

La plupart des bâtiments de ce type mettent en oeuvre des dispositifs de pompage nécessitant des installations mécaniques, hydrauliques et électriques relativement complexes, et donc coûteux à produire et à maintenir en bon état de marche. De plus, un opérateur destiné à contrôler le fonctionnement de tels dispositifs devra posséder à cet effet de bonnes connaissances en mécanique, en hydraulique et en électricité, que seule une formation coûteuse peut apporter.Most buildings of this type implement pumping devices requiring relatively complex mechanical, hydraulic and electrical installations, and therefore expensive to produce and maintain in good working order. In addition, an operator to control the operation of such devices must have for this purpose good knowledge of mechanics, hydraulics and electricity, only expensive training can provide.

On connaît également des bâtiments tels que celui décrit dans le document de brevet US 4 545 315 qui est muni de moyens de rétentions de déchets solides uniquement et qui est piloté par télécommande. Ce bâtiment permet de ramasser des objets ou des animaux lors de son trajet sur l'eau.Also known buildings such as that described in the patent document US 4,545,315 which is provided with solid waste retention means only and which is controlled by remote control. This building can pick up objects or animals while traveling on the water.

Le document de brevet US 4 595 510 décrit un bâtiment muni de moyens de rétention de déchets liquides dont une cuve est placée légèrement en dessous de la surface de l'eau. Un dispositif de pompage est utilisé pour transférer les déchets liquides de cette cuve jusque dans des cuves annexes.The patent document US 4,595,510 describes a building provided with means for retaining liquid waste, one tank of which is placed slightly below the surface of the water. A pumping device is used to transfer the liquid waste from this tank into additional tanks.

Le document de brevet WO 00/27694 décrit un bâtiment comportant des moyens de rétention de déchets liquides placé sur un trajet d'un canal d'eau à l'intérieur du bâtiment. Une roue à aube est placée sur le trajet de l'eau en amont des moyens de rétention de façon à y transférer les déchets liquides. Deux autres roues à aubes sont également utilisées pour évacuer l'eau du bâtiment. Le document US 4 372 054 décrit un bâtiment comportant toutes les caractéristiques du préambule de la revendication 1.The patent document WO 00/27694 discloses a building having means for retaining liquid waste placed on a path of a water channel inside the building. A paddle wheel is placed on the water path upstream of the holding means to transfer liquid waste therein. Two other paddle wheels are also used to evacuate water from the building. The document US 4,372,054 describes a building having all the features of the preamble of claim 1.

L'un des buts de l'invention est de fournir un bâtiment capable de recueillir des déchets sans faire appel à un dispositif de pompage ou de ramassage spécifique,
dispositif dont le contrôle nécessiterait des actions supplémentaires à celles nécessaires pour manoeuvrer ledit bâtiment.One of the aims of the invention is to provide a building capable of collecting waste without using a specific pumping or picking device,
device whose control would require actions additional to those necessary to maneuver the said building.

En effet, un bâtiment conforme au paragraphe introductif est du type comme décrit dans revendication independente 1.Indeed, a building according to the introductory paragraph is of the type as described in independent claim 1.

L'invention garantit ainsi une activation automatique des moyens de rétention par simple établissement d'une circulation d'eau le long du canal d'écoulement d'eau qui dirigera alors vers les moyens de rétention les divers déchets présents à l'entrée d'eau dudit canal, la sortie d'eau restituant en quelque sorte une eau filtrée, puisque débarrassée desdits déchets.The invention thus guarantees automatic activation of the retention means by simple establishment of a circulation of water along the water flow channel which will then direct the various waste present at the entrance to the means of retention. water of said channel, the water outlet returning a sort of filtered water, since cleared of said waste.

Les moyens de rétention pourront par exemple être activés par le seul mouvement du bâtiment, et ne nécessiteront donc aucun mécanisme ou contrôle particuliers dans le cours de leur fonctionnement. Il suffira à un opérateur de piloter le bâtiment et de le diriger vers les déchets qu'il souhaite recueillir, le bâtiment avalant en quelque sorte lesdits déchets dans le fil de son mouvement. La seule compétence nécessaire à l'opérateur pour contrôler de telles opérations de nettoyage sera une aptitude à manoeuvrer un tel bâtiment dans ses conditions d'utilisation, c'est-à-dire dans un port, sur une rivière, etc.The means of retention may for example be activated by the movement of the building alone, and therefore require no particular mechanism or control in the course of their operation. It will be enough for an operator to steer the building and direct it towards the waste that it wishes to collect, the building swallowing somehow said waste in the thread of its movement. The only skill necessary for the operator to control such cleaning operations will be an ability to maneuver such a vessel in its conditions of use, ie in a port, on a river, etc.

Selon un premier aspect de l'invention, les moyens de rétention incluent des moyens de rétention de déchets liquides disposés sur un premier trajet dudit canal.According to a first aspect of the invention, the retention means include liquid waste retention means disposed on a first path of said channel.

Les moyens de rétention de déchets liquides permettront par exemple de recueillir des nappes d'hydrocarbure présentes au voisinage de la surface du plan ou cours d'eau sur laquelle le bâtiment conforme à l'invention est destiné à évoluer.The liquid waste retention means will allow for example to collect hydrocarbon layers present in the vicinity of the surface of the plan or watercourse on which the building according to the invention is intended to evolve.

En vue d'une telle application, le bâtiment conforme à l'invention pourra inclure en outre des moyens de chauffage d'une surface supérieure du canal d'écoulement d'eau, destinés à fluidifier les hydrocarbures, qui pourront se présenter sous forme de galettes ou de boulettes semi-rigides.For such an application, the building according to the invention may further include means for heating an upper surface of the water flow channel, intended to fluidify the hydrocarbons, which may be in the form of patties or semi-rigid pellets.

Selon un mode de réalisation particulier de cette première variante, les moyens de rétention de déchets liquides incluent une cuve de rétention destinée à être traversée par le canal d'écoulement d'eau lorsque le bâtiment est en mouvement.According to a particular embodiment of this first variant, the liquid waste retention means include a holding tank intended to be traversed by the water flow channel when the building is in motion.

Le bâtiment pourra inclure en outre des moyens de régulation d'une température intérieure de la cuve de rétention, qui permettront de maintenir dans un état liquide des hydrocarbures contenus dans la cuve, ce qui facilitera une vidange ultérieure de la cuve, par exemple par pompage.The building may also include means for regulating an internal temperature of the holding tank, which will maintain in a liquid state hydrocarbons contained in the tank, which will facilitate subsequent emptying of the tank, for example by pumping .

Selon une caractéristique de l'invention, la sortie des moyens de rétention de déchets liquides est destinée à être obstruée par des moyens de fermeture lorsque lesdits moyens de rétention de déchets liquide sont remplie de déchets liquides.According to one characteristic of the invention, the outlet of the liquid waste retention means is intended to be obstructed by closure means when said liquid waste retention means are filled with liquid waste.

Les hydrocarbures étant par nature plus légers que l'eau, ils s'accumuleront au fur et à mesure dans la cuve de rétention décrite ci-dessus qui permettra cependant à l'eau, débarrassée de ces hydrocarbures, de s'échapper par le fond de ladite cuve, laquelle cuve permet donc une collecte et un stockage de déchets liquides sans pour autant interrompre la circulation d'eau le long du canal d'écoulement entre l'entrée et la sortie d'eau. Cette circulation ne sera interrompue que lorsque la cuve de rétention sera pleine, c'est-à-dire lorsque le bâtiment ne pourra plus recueillir à son bord de déchets liquides supplémentaires. Une telle interruption de circulation est alors réalisée par les moyens de fermeture.Since hydrocarbons are by nature lighter than water, they will gradually accumulate in the retention tank described above which will however allow the water, freed of these hydrocarbons, to escape through the bottom. said tank, which thus allows a collection and storage of liquid waste without interrupting the flow of water along the flow channel between the inlet and the outlet water. This circulation will be interrupted only when the holding tank is full, that is to say when the building will no longer collect on board additional liquid waste. Such a circulation interruption is then performed by the closing means.

Les moyens de fermeture comprendront de préférence un flotteur présentant au moins une surface apte à recouvrir l'orifice formant la sortie de la cuve, lequel flotteur est réalisé en un matériau présentant une masse volumique supérieure à celle des déchets liquides et inférieure à celle de l'eau.The closure means will preferably comprise a float having at least one surface capable of covering the orifice forming the outlet of the tank, which float is made of a material having a density greater than that of the liquid waste and lower than that of the 'water.

Ce mode de réalisation des moyens de fermeture est avantageux en ce qu'il permet une fermeture automatique de la cuve de rétention lorsque ladite cuve est pleine. En effet, le flotteur étant plus lourd que les hydrocarbures maintenus dans la cuve, il sera progressivement enfoncé vers l'orifice pratiqué dans le fond de la cuve à mesure que celle-ci se remplira de déchets liquides. Lorsque la cuve sera pleine, le flotteur se trouvera naturellement plaqué contre ledit orifice et bouchera donc la sortie de la cuve.This embodiment of the closure means is advantageous in that it allows automatic closure of the holding tank when said tank is full. Indeed, since the float is heavier than the hydrocarbons held in the tank, it will gradually be pushed towards the hole in the bottom of the tank as it will fill with liquid waste. When the tank is full, the float will naturally be pressed against said orifice and thus plug the outlet of the tank.

Selon un deuxième aspect de l'invention, les moyens de rétention incluent des moyens de rétention de déchets solides disposés sur un deuxième trajet dudit canal.According to a second aspect of the invention, the retention means include solid waste retention means arranged on a second path of said channel.

Les moyens de rétention pourront inclure à la fois des moyens de rétention de déchets liquides et moyens de rétention de déchets solides. Le fait qu'ils soient alors placés sur des premier et deuxième trajets permet d'assurer que la circulation d'eau le long de l'un des deux trajets ne sera pas interrompue du seul fait d'une interruption de la circulation d'eau le long de l'autre trajet.Retention means may include both liquid waste retention means and solid waste retention means. The fact that they are then placed on first and second paths makes it possible to ensure that the flow of water along one of the two paths will not be interrupted solely because of an interruption of the water circulation. along the other path.

Si les moyens de rétention de déchets solides sont disposés en amont du canal d'écoulement d'eau par rapport aux moyens de rétention de déchets liquides, les premier et deuxième trajets dudit canal pourront être confondus entre l'entrée du canal et une sortie des moyens de rétention de déchets solides.If the solid waste retention means are arranged upstream of the water flow channel relative to the liquid waste retention means, the first and second paths of said channel may be merged between the inlet of the channel and an outlet of the means of solid waste retention.

Un tel agencement des moyens de rétention de déchets liquides et des moyens de rétention de déchets solides permet de réduire l'encombrement du bâtiment tout en minimisant les risques pour que des interruptions intempestives ne surviennent dans les trajets d'écoulement d'eau. En effet, c'est principalement lorsque les moyens de rétention de déchets liquides sont remplis par de tels déchets qu'une interruption de circulation d'eau survient, afin d'éviter un rejet de ces déchets vers la sortie d'eau du bâtiment. La disposition des moyens de rétention de déchets solides en amont des moyens de rétention de déchets liquides, les premier et deuxième trajets divergeant en aval des moyens de rétention de déchets solides, permet d'assurer qu'une interruption de la circulation d'eau au travers des moyens de rétention de déchets liquides n'affectera pas de manière significative le fonctionnement des moyens de rétention de déchets solides.Such an arrangement of the liquid waste retention means and solid waste retention means reduces the bulk of the building while minimizing the risk that untimely interruptions occur in the water flow paths. Indeed, it is mainly when the liquid waste retention means are filled with such waste that an interruption of water flow occurs, to avoid a discharge of this waste to the water outlet of the building. The arrangement of the solid waste retention means upstream of the liquid waste retention means, the first and second divergent paths downstream of the solid waste retention means, makes it possible to ensure that an interruption of the flow of water at through means of liquid waste retention will not significantly affect the operation of the solid waste retention means.

Les moyens de rétention de déchets solides pourront être réalisés de diverses manières, et pourront en particulier inclure au moins une grille disposée en travers du canal d'écoulement d'eau.The solid waste retention means may be made in various ways, and may in particular include at least one grid disposed across the water flow channel.

Les moyens de rétention de déchets solides incluront de préférence une première et une deuxième grilles formant saillie l'une par rapport à l'autre et solidaires entre elles de manière à former un ensemble, lequel ensemble est mobile par rapport audit bâtiment.The solid waste retention means will preferably include a first and a second grid projecting relative to each other and integral with each other so as to form an assembly, which assembly is movable relative to said building.

Ce mode de réalisation préféré des moyens de rétention de déchets solides permet une collecte et un stockage efficace desdits déchets, et permet en outre de déverser aisément lesdits déchets dans un récipient lorsque le bâtiment devra en être débarrassé.This preferred embodiment of the solid waste retention means allows efficient collection and storage of said waste, and further allows to easily discharge said waste in a container when the building will have to be disposed of.

La mise en mouvement du bâtiment peut être réalisée de multiples manières, par exemple au moyen d'un moteur à hélice électrique ou à explosion, tel un moteur hors-bord sur lequel auront été adaptés des moyens de déviation de flux. Selon un troisième aspect de l'invention, un bâtiment tel que décrit plus haut inclura en outre une turbine destinée à entraîner ledit bâtiment en mouvement, laquelle turbine présentera une entrée disposée en aval de la sortie du canal d'écoulement d'eau et une sortie destinée à produire un jet d'eau vers l'extérieur dudit bâtiment, en dessous de la surface du plan ou cours d'eau.The movement of the building can be carried out in multiple ways, for example by means of an electric propeller or explosion motor, such as an outboard motor on which flow deflection means have been adapted. According to a third aspect of the invention, a building as described above will further include a turbine for driving said moving vessel, which turbine will have an inlet disposed downstream of the outlet of the water flow channel and a outlet intended to produce a jet of water to the outside of said building, below the surface of the plan or stream.

Ce troisième aspect de l'invention est avantageux en ce que, la turbine étant placée dans le prolongement du canal d'écoulement d'eau, ladite turbine peut réguler le débit d'écoulement d'eau dans ledit canal, et en particulier accélérer ce débit, ce qui est particulièrement utile par exemple pendant une phase de démarrage au cours de laquelle, bien que le mouvement du bâtiment y soit relativement lent, une collecte efficace des déchets est assurée par un fort débit imprimé par la turbine dans le canal d'écoulement d'eau.This third aspect of the invention is advantageous in that, the turbine being placed in the extension of the water flow channel, said turbine can regulate the flow rate of water flow in said channel, and in particular accelerate this flow, which is particularly useful during a start-up phase during which, although the movement of the building is relatively slow, efficient collection of waste is ensured by a high flow rate printed by the turbine in the channel of water flow.

La sortie de la turbine sera avantageusement munie d'un déflecteur présentant une position réglable, laquelle position déterminera une direction du jet d'eau produit par ladite turbine.The outlet of the turbine will advantageously be provided with a deflector having an adjustable position, which position will determine a direction of the water jet produced by said turbine.

Le déflecteur permettra de manoeuvrer le bâtiment sans requérir d'autre moyen dédié à cet effet spécifique, comme un gouvernail annexe.The deflector will allow to maneuver the building without requiring other means dedicated to this specific effect, such as an auxiliary rudder.

Dans le cas où le bâtiment est un monocoque, l'entrée et la sortie d'eau peuvent être pratiquées dans la proue et dans la poupe de ladite coque, qui comportera une partie creuse délimitant le canal d'écoulement d'eau.In the case where the vessel is a monohull, the water inlet and outlet can be made in the bow and stern of said hull, which will include a hollow portion delimiting the water flow channel.

Cependant, selon un quatrième aspect de l'invention, un bâtiment tel que décrit plus haut sera muni d'au moins deux coques solidaires l'une de l'autre et sensiblement parallèles entre elles, une distance séparant lesdites coques délimitant une largeur du canal d'écoulement d'eau.However, according to a fourth aspect of the invention, a building as described above will be provided with at least two shells integral with one another and substantially parallel to each other, a distance separating said shells delimiting a width of the channel water flow.

Une telle structure multicoques confère au bâtiment une stabilité et une maniabilité plus grande, et permet de réaliser de manière simple le canal d'écoulement d'eau, qui est formé de manière naturelle entre les coques.Such a multihull structure gives the building greater stability and maneuverability, and allows for a simple way of producing the water flow channel, which is formed naturally between the hulls.

Un tel bâtiment pourra en outre inclure un carénage reliant entre eux des fonds desdites coques, une distance séparant ledit carénage de la surface du plan ou cours d'eau délimitant une profondeur du canal d'écoulement.Such a building may further include a fairing connecting between them funds of said hulls, a distance separating said fairing from the surface of the plan or watercourse delimiting a depth of the flow channel.

Le carénage permet d'isoler le canal d'écoulement d'eau de tout remous en provenance du dessous du bâtiment qui risquerait de perturber le fonctionnement des moyens de rétention.The fairing makes it possible to isolate the water flow channel from any eddy coming from the underside of the building which could disturb the operation of the retention means.

Ce carénage pourra de plus être muni d'éléments roulants tels des roues pour faciliter des opérations de déplacement du bâtiment sur la terre ferme.This fairing may further be provided with rolling elements such as wheels to facilitate operations of movement of the building on the mainland.

La Fig. 1 représente schématiquement un bâtiment BAT conforme à un mode de réalisation particulier de l'invention. Ce bâtiment BAT est destiné à évoluer sur une surface d'un plan ou d'un cours d'eau, et à recueillir à son bord des déchets présents à ladite surface. Le bâtiment BAT inclut des moyens de rétention (MRS, MRL) aptes à capter et à retenir des déchets, et à être activés par un mouvement du bâtiment. Ces moyens de rétention (MRS, MRL) sont représentés en traits gras sur la présente figure.The Fig. 1 schematically represents a building BAT according to a particular embodiment of the invention. This building BAT is intended to evolve on a surface of a plan or a watercourse, and collect on board waste present on said surface. The BAT building includes retention means (MRS, MRL) capable of capturing and holding waste, and to be activated by a movement of the building. These retention means (MRS, MRL) are shown in bold lines in the present figure.

Le bâtiment BAT comporte dans cet exemple de réalisation deux coques CQ1 et CQ2 solidaires l'une de l'autre et sensiblement parallèles entre elles. Ces coques délimitent entre elles un canal d'écoulement d'eau destiné à relier entre elles une entrée et une sortie d'eau EO et SO lorsque le bâtiment BAT est en mouvement, les moyens de rétention (MRS, MRL) étant disposés sur au moins un trajet dudit canal.The building BAT comprises in this embodiment two shells CQ1 and CQ2 integral with each other and substantially parallel to each other. These shells delimit between them a water flow channel intended to connect between them an inlet and a water outlet EO and SO when the BAT building is moving, the retention means (MRS, MRL) being arranged on at least one path of said channel.

Les moyens de rétention (MRS, MRL) incluent des moyens de rétention de déchets liquides MRL disposés sur un premier trajet dudit canal. Ces moyens de rétention de déchets liquides MRL incluent une cuve de rétention CUV destinée à être traversée par le canal d'écoulement d'eau lorsque le bâtiment BAT est en mouvement.Retention means (MRS, MRL) include means for retaining liquid waste MRL disposed on a first path of said channel. These liquid waste retention means MRL include a retention tank CUV intended to be traversed by the water flow channel when the building BAT is in motion.

Le bâtiment BAT inclut ici des moyens de chauffage HM d'une surface supérieure du canal d'écoulement d'eau, destinés à fluidifier des déchets liquides formés par des hydrocarbures, qui pourraient se présenter sous forme de galettes ou de boulettes semi-liquides. Ces moyens de chauffage HM pourront par exemple émettre un rayonnement électromagnétique EMW, sous forme d'ondes infra-rouge ou de micro-ondes, dont l'amplitude et la longueur d'onde auront été préalablement réglées de manière à assurer une pénétration dudit rayonnement EMW sur une profondeur De prédéterminée, qui sera par exemple comprise entre 5 et 15 centimètres.The BAT building here includes HM heating means of an upper surface of the water flow channel, intended to fluidify liquid waste formed by hydrocarbons, which could be in the form of slabs or semi-liquid pellets. These HM heating means may for example emit EMW electromagnetic radiation, in the form of infra-red waves or microwaves, the amplitude and wavelength have been previously adjusted so as to ensure penetration of said radiation EMW on a predetermined depth, which will be for example between 5 and 15 centimeters.

Le bâtiment BAT inclura en outre avantageusement des moyens de régulation d'une température intérieure de la cuve de rétention CUV, qui n'ont pas été représentés ici dans le but de ne pas encombrer inutilement la présente Figure, lesquels moyens de régulation permettront de maintenir dans un état liquide des hydrocarbures contenus dans la cuve CUV, en vue de faciliter une vidange ultérieure de la cuve, par exemple par pompage. Ces moyens de régulation pourront par exemple être constitués par des résistances électriques intégrées dans les parois de la cuve CUV, et destinées à être alimentées par un courant électrique lorsque la température intérieure de la cuve CUV descendra en-dessous d'une valeur de seuil prédéterminée.The BAT building will also advantageously include means for regulating an internal temperature of the holding tank CUV, which have not been represented here in order not to unnecessarily clutter this Figure, which control means will maintain in a liquid state hydrocarbons contained in the tank CUV, to facilitate subsequent emptying of the tank, for example by pumping. These regulation means may for example be constituted by electrical resistances integrated into the walls of the tank CUV, and intended to be supplied with an electric current when the internal temperature of the tank CUV will fall below a predetermined threshold value. .

Dans le mode de réalisation décrit ici, la cuve de rétention CUV présente :

  • . une entrée EL, destinée à être reliée à l'entrée EO du canal d'écoulement d'eau, matérialisée par un bord supérieur de ladite cuve, et destinée à être placée au voisinage de la surface de l'eau, et
  • . une sortie SL, destinée à être reliée à la sortie dudit canal SO, matérialisée par un orifice pratiqué dans un fond de la cuve de rétention CUV, et destinée à être obstruée par des moyens de fermeture, non-représentés ici, lorsque ladite cuve CUV est remplie de déchets liquides.
In the embodiment described here, the CUV holding tank has:
  • . an input EL, intended to be connected to the inlet EO of the water flow channel, materialized by an upper edge of said tank, and intended to be placed in the vicinity of the surface of the water, and
  • . an outlet SL, intended to be connected to the outlet of said channel SO, materialized by an orifice made in a bottom of the holding tank CUV, and intended to be obstructed by closure means, not shown here, when said tank CUV is filled with liquid waste.

Les moyens de rétention de déchets liquides MRL incluent ici également un entonnoir ENT destiné à diriger un flux d'eau vers la cuve de rétention CUV et à favoriser ainsi la création du premier trajet du canal d'écoulement d'eau.The liquid waste retention means MRL here also include a funnel ENT intended to direct a flow of water to the retention tank CUV and thus to promote the creation of the first path of the water flow channel.

Les moyens de rétention (MRS, MRL) incluent en outre des moyens de rétention de déchets solides MRS disposés en amont du canal d'écoulement d'eau par rapport aux moyens de rétention de déchets liquides MRL. Ces moyens de rétention de déchets solides MRS incluent une première et une deuxième grilles GR1 et GR2, disposées en travers du canal d'écoulement d'eau, formant saillie l'une par rapport à l'autre et solidaires entre elles de manière à former un ensemble (GR1, GR2), lequel ensemble est rendu mobile par rapport audit bâtiment au moyen d'une liaison pivot avec deux supports SUP solidaires des première et deuxième coques CQ1 et CQ2, laquelle liaison pivot autorise une rotation dudit ensemble (GR1, GR2) autour d'un axe de rotation A1.The retention means (MRS, MRL) further include MRS solid waste retention means arranged upstream of the water flow channel relative to the MRL liquid waste retention means. These solid waste retention means MRS include a first and a second grid GR1 and GR2, arranged across the water flow channel, projecting relative to each other and integral with each other so as to form a set (GR1, GR2), which assembly is made mobile with respect to said building by means of a pivot connection with two SUP supports integral with the first and second shells CQ1 and CQ2, which pivot connection allows a rotation of said assembly (GR1, GR2 ) about an axis of rotation A1.

Le bâtiment BAT inclut en outre une turbine TUR, commandée par un moteur MOT, et destinée à entraîner ledit bâtiment en mouvement, laquelle turbine présente une entrée disposée en aval de la sortie SO du canal d'écoulement d'eau et une sortie destinée à produire un jet d'eau vers l'extérieur dudit bâtiment BAT, en dessous de la surface du plan ou cours d'eau.The building BAT further includes a turbine TUR, controlled by a motor MOT, and intended to drive said building in motion, which turbine presents an inlet disposed downstream of the outlet SO of the water flow channel and an outlet for producing a jet of water to the outside of said building BAT, below the surface of the plane or stream.

La Fig.2 représente schématiquement ce bâtiment BAT, vu depuis son flanc bâbord, dans une première configuration de fonctionnement. Les éléments de ce bâtiment qui ont déjà été décrits ci-dessus sont munis des mêmes signes de référence et ne seront pas à nouveau décrits ici. Cette vue schématique permet cependant d'observer un déflecteur DEF dont est munie la sortie de la turbine commandée par le moteur MOT, lequel déflecteur DEF présente une position réglable qui détermine une direction du jet d'eau JO produit par ladite turbine. Cette vue schématique montre en outre un carénage CAR reliant entre eux les fonds des deux coques du bâtiment BAT.The Fig.2 schematically represents this building BAT, seen from its port side, in a first configuration of operation. The elements of this building that have already been described above are provided with the same reference signs and will not be described again here. This schematic view, however, makes it possible to observe a deflector DEF which is provided with the output of the turbine controlled by the motor MOT, which deflector DEF has an adjustable position which determines a direction of the jet of water OJ produced by said turbine. This schematic view also shows a CAR fairing connecting the bottoms of the two hulls of the BAT building.

Le bâtiment BAT évolue ici à la surface d'un plan d'eau, dont un niveau est représenté par une ligne NE. Dans cette première configuration, le déflecteur DEF est en position haute, de sorte que le jet d'eau JO produit par la turbine est dirigé vers l'arrière du bâtiment BAT, lequel se déplace alors vers l'avant à une vitesse Vbat. La vitesse relative du bâtiment vis-à-vis du plan d'eau donne naissance à un canal d'écoulement d'eau reliant entre elles l'entrée d'eau EO et la sortie d'eau SO. L'établissement de ce canal d'écoulement d'eau est en outre favorisé par le flux d'eau traversant la turbine, le débit de l'écoulement d'eau dans ce canal pouvant ainsi être régulé en agissant sur des commandes du moteur MOT.The BAT building evolves here on the surface of a body of water, a level of which is represented by a line NE. In this first configuration, the deflector DEF is in the up position, so that the jet of water OJ produced by the turbine is directed towards the rear of the building BAT, which then moves forward at a speed Vbat. The relative velocity of the building vis-à-vis the water body gives rise to a water flow channel interconnecting the water inlet EO and the outlet water SO. The establishment of this water flow channel is further favored by the flow of water through the turbine, the flow rate of the water flow in this channel can thus be regulated by acting on MOT motor controls. .

Les moyens de rétention de déchets liquides MRL sont disposés sur un premier trajet TRAJ1 du canal d'écoulement d'eau, les moyens de rétention de déchets solides formés par les première et deuxième grilles GR1 et GR2 étant disposés sur un deuxième trajet TRAJ2 dudit canal.The liquid waste retention means MRL are arranged on a first path TRAJ1 of the water flow channel, the solid waste retention means formed by the first and second grids GR1 and GR2 being arranged on a second path TRAJ2 of said channel .

Les première et deuxième grilles GR1 et GR2 qui forment les moyens de rétention de déchets solides étant disposés en amont du canal d'écoulement d'eau par rapport aux moyens de rétention de déchets liquides MRL, les premier et deuxième trajets TRAJ1 et TRAJ2 sont confondus entre l'entrée EO du canal d'écoulement d'eau et une sortie des moyens de rétention de déchets solides située ici entre la première grille GR1 et l'entonnoir ENT inclus dans les moyens de rétention de déchets liquides MRL.The first and second grids GR1 and GR2 which form the solid waste retention means being arranged upstream of the water flow channel with respect to the liquid waste retention means MRL, the first and second paths TRAJ1 and TRAJ2 coincide. between the inlet EO of the water flow channel and an outlet of the solid waste retention means located here between the first GR1 grid and the ENT funnel included in the MRL liquid waste retention means.

Un seuil réglable, non représenté ici, pourra être aménagé en amont des première et deuxième grilles GR1 et GR2 de manière à réguler les flux confondus des premier et deuxième trajets TRAJ1 et TRAJ2 en fonction d'un enfoncement du bâtiment BAT, lequel enfoncement pourrait par exemple être causé par une surcharge dudit bâtiment.An adjustable threshold, not shown here, may be arranged upstream of the first and second grids GR1 and GR2 so as to regulate the combined flow of the first and second paths TRAJ1 and TRAJ2 as a function of a depression of the building BAT, which depression could by example be caused by overloading the building.

Tout déchet solide DS présentant une dimension supérieure à un écart existant entre deux barreaux adjacents des première et deuxième grilles GR1 et GR2 est retenu par lesdites grilles à mesure que le bâtiment se déplace. Les première et deuxième grilles GR1 et GR2 ne font cependant pas obstacle au passage d'éléments liquides, et débarrassent ainsi par filtrage l'eau avalée par l'entrée d'eau EO des seuls déchets solides DS. L'eau présente à la sortie des moyens de rétention de déchets solides peut contenir, au voisinage de la surface, des déchets liquides DL, représentés ici par des hachures au voisinage du niveau d'eau NE, tels des nappes d'hydrocarbures comme cela est souvent le cas dans des eaux portuaires. Ces déchets liquides DL seront orientés le long du premier trajet TRAJ1 par l'entonnoir ENT vers l'entrée EL de la cuve de rétention où ils seront accumulés en surface, puisque leur masse volumique est inférieure à celle de l'eau qui pourra, elle, s'échapper au travers de l'orifice de sortie de la cuve vers la sortie SO du canal d'écoulement d'eau. La création du flux s'écoulant le long du premier trajet TRAJ1 est en outre favorisée dans ce mode de réalisation par un effet Venturi généré par la forme particulière de la cuve de rétention, qui présente ici une surface décroissante dans le sens de la profondeur.Any solid waste DS having a dimension greater than a gap existing between two adjacent bars of the first and second grids GR1 and GR2 is retained by said grids as the building moves. The first and second grids GR1 and GR2, however, do not impede the passage of liquid elements, and thus filter the water swallowed by the water inlet EO only solid waste DS. The water present at the outlet of the solid waste retention means may contain, in the vicinity of the surface, liquid waste DL, represented here by hatching in the vicinity of the water level NE, such as oil slicks such as this. is often the case in port waters. This liquid waste DL will be oriented along the first path TRAJ1 by the funnel ENT to the inlet EL of the holding tank where they will accumulate on the surface, since their density is lower than that of the water which can , escape through the outlet of the tank to the outlet SO of the water flow channel. The creation of the flow flowing along the first path TRAJ1 is furthermore favored in this embodiment by a Venturi effect generated by the particular shape of the holding tank, which here has a decreasing surface in the direction of the depth.

Le deuxième trajet TRAJ2 du canal d'écoulement d'eau permettra en outre à de l'eau non souillée par des déchets liquides, puisque prélevée plus en profondeur, de s'écouler entre le carénage CAR et le dessous de la cuve de rétention vers la sortie d'eau SO. Ce deuxième trajet TRAJ2 ne sera pas perturbé de manière significative si le premier trajet TRAJ1 est interrompu.The second path TRAJ2 of the water flow channel will also allow water unstained by liquid waste, since taken at greater depth, to flow between the fairing CAR and the underside of the holding tank towards the outlet of water SO. This second path TRAJ2 will not be significantly disturbed if the first path TRAJ1 is interrupted.

Les moyens de rétention de déchets liquides MRL incluent des moyens de fermeture destinés à obstruer la cuve de rétention lorsque celle-ci est remplie de déchets liquides DL. Ces moyens de fermeture sont ici constitués par un flotteur FL, réalisé en un matériau présentant une masse volumique supérieure à celle des déchets liquides DL et inférieure à celle de l'eau, de sorte qu'il est par nature maintenu en position juste en dessous d'une ligne de séparation entre les déchets liquides DL et l'eau contenus ensemble dans la cuve de rétention. Ceci permet une fermeture automatique de la cuve de rétention lorsque ladite cuve est pleine. En effet, le flotteur FL sera progressivement enfoncé vers l'orifice pratiqué dans le fond de la cuve à mesure que celle-ci se remplira de déchets liquides DL. Lorsque la cuve sera pleine, le flotteur se trouvera naturellement plaqué contre ledit orifice et bouchera donc la sortie de la cuve.The liquid waste retention means MRL include closure means for obstructing the holding tank when it is filled with DL liquid waste. These closure means are here constituted by a float FL, made of a material having a density greater than that of liquid waste DL and lower than that of water, so that it is by nature maintained in position just below a separation line between the liquid waste DL and the water contained together in the holding tank. This allows automatic closure of the holding tank when said tank is full. Indeed, the float FL will be progressively pushed towards the hole made in the bottom of the tank as it will be filled with DL liquid waste. When the tank is full, the float will naturally be pressed against said orifice and thus plug the outlet of the tank.

La Fig.3 illustre un tel état de fait sous forme d'une deuxième configuration, dans laquelle le premier trajet TRAJ1 est interrompu du fait d'une fermeture par le flotteur FL de l'orifice pratiqué dans le fond de la cuve des moyens de rétention MRL de déchets liquides DL. Pour éviter que ladite cuve ne déborde en présence de remous pouvant faire varier brusquement le niveau d'eau NE, une trappe de fermeture TF a en outre été actionnée pour obstruer l'entrée EL de la cuve de rétention. Le deuxième trajet TRAJ2 n'est pas affecté de manière significative par l'interruption du premier trajet TRAJ1, de sorte que de l'eau continue à s'écouler dans le canal d'écoulement reliant entre elles l'entrée d'eau EO et la sortie d'eau SO, le bâtiment BAT continuant à se déplacer à la vitesse Vbat. La persistance de l'existence de ce canal, obtenue grâce au deuxième trajet TRAJ2, permet aux moyens de rétention de déchets solides de continuer à fonctionner, comme le montre la présence d'un nouveau déchet solide DS collecté par les première et deuxième grilles GR1 et GR2.The Fig.3 illustrates such a state of affairs in the form of a second configuration, in which the first path TRAJ1 is interrupted because of a closure by the float FL of the orifice made in the bottom of the tank of the waste retention means MRL DL liquids. To prevent said tank from overflowing in the presence of turbulence that can cause the water level NE to change suddenly, a closing flap TF has also been actuated to obstruct the inlet EL of the holding tank. The second path TRAJ2 is not significantly affected by the interruption of the first path TRAJ1, so that water continues to flow in the flow channel connecting the water inlet EO and the SO water outlet, the BAT building continuing to move at the Vbat speed. The persistence of the existence of this channel, obtained through the second path TRAJ2, allows the solid waste retention means to continue to operate, as shown by the presence of a new solid waste DS collected by the first and second grids GR1 and GR2.

La Fig.4 illustre une troisième configuration de fonctionnement possible d'un bâtiment BAT conforme au mode de réalisation particulier décrit ci-dessus. Dans cette troisième configuration, le déflecteur DEF dont est munie la sortie de la turbine commandée par le moteur MOT est en position basse, de sorte qu'il interfère avec le jet d'eau JO produit par ladite turbine en le défléchissant vers l'avant du bâtiment BAT. Ceci a pour effet d'inverser le sens de la vitesse Vbat dudit bâtiment BAT, et donc de mouvoir ledit bâtiment en marche arrière. Une telle faculté de déplacement en marche arrière est particulièrement utile dans des situations où le bâtiment BAT ne dispose que d'une faible marge de manoeuvre, comme dans des installations portuaires où l'espace disponible est généralement occupé autant que possible par des navires à quai ou en cours d'accostage ou de départ. Le déflecteur DEF pourra d'ailleurs être constitué par un assemblage d'un demi-déflecteur bâbord et d'un demi-déflecteur tribord, ce dernier n'étant pas représenté sur la présente figure où seul le demi-réflecteur bâbord est apparent, lesdits demi-déflecteurs étant alors contrôlables séparément pour infléchir la direction du jet d'eau JO produit par la turbine vers bâbord ou vers tribord.The Fig.4 illustrates a third possible operating configuration of a BAT building according to the particular embodiment described above. In this third configuration, the deflector DEF which is provided with the output of the turbine controlled by MOT motor is in the low position, so that it interferes with the jet of water OJ produced by said turbine by deflecting it forward BAT building. This has the effect of reversing the direction of the speed Vbat of said building BAT, and thus to move said building in reverse. Such a faculty of displacement in reversing is particularly useful in situations where the BAT building has only a small margin of maneuver, such as in port facilities where available space is generally occupied as much as possible by ships at berth or berthing or departure. The deflector DEF may also be constituted by an assembly of a port half-deflector and a starboard half-deflector, the latter not being shown in the present figure where only the port half-reflector is apparent, said The baffles are then controllable separately to bend the direction of the jet of water OJ produced by the turbine to port or starboard.

Il est à noter que, même lorsque la direction du mouvement du bâtiment BAT est inversée, comme c'est le cas dans cette troisième configuration, le flux d'eau généré par la turbine permet de préserver un débit d'écoulement suffisant entre l'entrée d'eau EO et la sortie d'eau SO pour maintenir activés les moyens de rétention (GR1, GR2) de déchets solides DS et les moyens de rétention MRL de déchets solides DL, aucun des premier et deuxième trajet TRAJ1 et TRAJ2 n'étant alors interrompu, tout au moins jusqu'au remplissage de la cuve de rétention de déchets liquides DL conformément à l'exposé qui précède.It should be noted that, even when the direction of movement of the building BAT is reversed, as is the case in this third configuration, the flow of water generated by the turbine makes it possible to preserve a sufficient flow of flow between the EO water inlet and the SO water outlet to maintain activated the retention means (GR1, GR2) of solid waste DS and the MRL retention means of solid waste DL, none of the first and second path TRAJ1 and TRAJ2 n ' being then interrupted, at least until the filling of the DL liquid waste holding tank in accordance with the preceding discussion.

Dans une configuration toute particulière, il pourra même advenir que le déflecteur DEF soit orienté de sorte que le jet d'eau JO produit par la turbine ait une direction verticale. La vitesse Vbat du bâtiment BAT par rapport au plan ou cours d'eau sera alors nulle, une fois tout effet d'inertie dissipé, mais le débit d'écoulement entre l'entrée d'eau EO et la sortie d'eau SO sera préservé et maintiendra activés les moyens de rétention (GR1, GR2) de déchets solides DS et les moyens de rétention MRL de déchets solides DL, bien que le mouvement du bâtiment BAT ait été interrompu.In a very particular configuration, it may even happen that the deflector DEF is oriented so that the jet of water OJ produced by the turbine has a vertical direction. The speed Vbat of the building BAT relative to the plane or watercourse will then be zero, once any effect of inertia dissipated, but the flow rate between the water inlet EO and the water outlet SO will be preserved and will keep activated the means of retention (GR1, GR2) of solid waste DS and the retention means MRL of solid waste DL, although the movement of the building BAT has been interrupted.

La Fig.5 illustre une quatrième configuration de fonctionnement possible d'un bâtiment BAT conforme au mode de réalisation particulier décrit ci-dessus. Dans cette quatrième configuration, le bâtiment BAT a été mis à quai en vue de décharger les divers déchets qu'il a recueillis à son bord. A cet effet, l'ensemble constitué par les première et deuxième grilles GR1 et GR2 a subi une rotation autour de l'axe A1 de la liaison pivot liant ledit ensemble (GR1, GR2) aux supports SUP, laquelle liaison pivot confère dans cet exemple audit ensemble (GR1, GR2) sa mobilité par rapport au bâtiment BAT. Dans d'autres modes de réalisation, l'ensemble constitué par les première et deuxième grilles GR1 et GR2 pourra être entièrement amovible. Les déchets solides DS collectés et stockés par les moyens de rétention de déchets solides constitués par lesdites première et deuxième grilles GR1 et GR2 sont alors déversés dans une benne BEN, suspendues dans cet exemple à un palan mobile PAL. Les déchets liquides DL contenus dans la cuve de rétention, dont l'entrée et la sortie auront été préalablement fermées respectivement par la trappe de fermeture TF et le flotteur FL, seront quant à eux extraits au moyen d'un tuyau de vidange TUY développant une force d'aspiration ASP.The Fig.5 illustrates a fourth possible operating configuration of a BAT building according to the particular embodiment described above. In this fourth configuration, the BAT building was docked to unload the various waste it collected on board. For this purpose, the assembly constituted by the first and second grids GR1 and GR2 has been rotated about the axis A1 of the Pivot link linking said assembly (GR1, GR2) supports SUP, which pivot connection confers in this example to said set (GR1, GR2) its mobility relative to the building BAT. In other embodiments, the assembly constituted by the first and second grids GR1 and GR2 may be entirely removable. The solid waste DS collected and stored by the solid waste retention means constituted by said first and second grids GR1 and GR2 are then dumped into a bin BEN, suspended in this example to a PAL hoist. The liquid waste DL contained in the holding tank, the inlet and outlet of which have previously been closed respectively by the closing hatch TF and the float FL, will be extracted by means of a drain pipe TUY developing a ASP suction force.

On notera que de telles opérations de déchargement du bâtiment BAT peuvent être également opérées à terre, la surface inférieure du carénage CAR du bâtiment BAT étant munie d'éléments roulants, dans cet exemple une roue avant R1 et deux roues arrière R2 et R3 dont seul la roue bâbord est apparente, pour faciliter des opérations de déplacement du bâtiment BAT sur la terre ferme. Ces éléments roulants R1, R2 et R3 seront en outre très utiles pour charger ledit bâtiment BAT sur une plate-forme ou une remorque en vue d'un transport, par exemple par voie terrestre, ainsi que pour mettre à flot le bâtiment BAT, puisqu'il suffira alors de le faire rouler le long d'une grève, ce qui évite de recourir à un grutage.It should be noted that such unloading operations of the building BAT can also be carried out on the ground, the lower surface of the fairing CAR of the building BAT being provided with rolling elements, in this example a front wheel R1 and two rear wheels R2 and R3 of which only the port wheel is visible, to facilitate moving operations of the BAT building on the mainland. These rolling elements R1, R2 and R3 will also be very useful for loading said BAT building on a platform or a trailer for transport, for example by land, as well as for launching the building BAT, since it will then be enough to roll it along a strike, which avoids resorting to a crane.
