Description

La présente invention concerne le domaine de la dépollution des eaux, et porte plus particulièrement sur un dispositif de collecte de déchets flottants.The present invention relates to the field of water pollution control, and relates more particularly to a device for collecting floating waste.

On connaît, par exemple du brevet US3823828 A , un dispositif de collecte de déchets flottants sous forme solide ou d'hydrocarbures constitué par une embarcation comportant une turbine permettant à la fois de propulser le dispositif et de créer un écoulement d'eau à travers un espace de collecte. Toutefois, de tels dispositifs se révèlent peu maniables et ne permettent pas un balayage quadrillé d'une zone à dépolluer.We know, for example from the patent US3823828A , a device for collecting floating waste in solid form or hydrocarbons consisting of a boat comprising a turbine making it possible both to propel the device and to create a flow of water through a collection space. However, such devices prove to be unwieldy and do not allow grid scanning of an area to be cleared.

Il existe donc un besoin pour un dispositif de collecte de déchets flottants d'une grande maniabilité, simple de construction tout en demeurant polyvalent, et qui puisse se déplacer et adapter son parcours de façon autonome.There is therefore a need for a device for collecting floating waste of great maneuverability, simple in construction while remaining versatile, and which can move and adapt its route independently.

Le Demandeur se propose donc de répondre à ces besoins par un dispositif de collecte équipé de deux turbines. Les deux turbines assurent à la fois la propulsion vers l'avant et l'aspiration des déchets, l'une des deux turbines étant capable d'inversion de son sens de rotation et étant couplée à un volet mobile d'un déflecteur de façon à permettre également la propulsion vers l'arrière du dispositif. Par ailleurs, le dispositif de collecte comprend des moyens de commande et facultativement des moyens de communication à distance de sorte qu'il est configuré pour fonctionner soit de façon télécommandée, soit de façon autonome, en suivant un programme prédéfini, tout en étant apte à adapter son parcours en fonction des situations détectées, comme les obstacles ou les types de pollution rencontrées.The Applicant therefore proposes to meet these needs with a collection device equipped with two turbines. The two turbines provide both forward propulsion and waste suction, one of the two turbines being capable of reversing its direction of rotation and being coupled to a movable flap of a deflector so as to also allow rearward propulsion of the device. Furthermore, the collection device comprises control means and optionally remote communication means so that it is configured to operate either remotely or autonomously, following a predefined program, while being able to adapt their route according to the situations detected, such as obstacles or types of pollution encountered.

La présente invention a donc pour objet un dispositif de collecte de déchets flottants à la surface de l'eau comprenant un châssis flottant équipé de moyens de flottaison et présentant une ouverture de collecte formée au moins en partie sous la ligne de flottaison du châssis, l'ouverture s'ouvrant sur une zone d'admission de déchets formée dans le châssis flottant, ladite zone d'admission de déchets étant équipée des moyens de stockage de déchets à l'intérieur du châssis flottant, les moyens de stockage étant configurés pour autoriser un passage de l'eau vers une sortie du châssis flottant mais retenir les déchets flottants, caractérisé par le fait que le dispositif de collecte de déchets flottants comprend en outre une première turbine et une deuxième turbine, montées sur le châssis flottant sous la ligne de flottaison en aval de la sortie du châssis flottant pour aspirer l'eau de l'ouverture de collecte vers la sortie pour provoquer un déplacement correspondant du châssis flottant, une troisième turbine montée perpendiculairement aux première et deuxième turbines pour autoriser un déplacement du châssis flottant dans une direction perpendiculaire à l'écoulement du fluide dans le châssis flottant provoqué par les première et deuxième turbines, et un volet mobile associé à la deuxième turbine, le volet étant monté entre la sortie et la deuxième turbine de telle sorte que dans un premier sens de rotation de la deuxième turbine, le volet est dans une première position autorisant un passage d'eau de la sortie vers la deuxième turbine et dans un second sens de rotation de la deuxième turbine, le volet est dans une deuxième position empêchant un passage d'eau entre la sortie et la deuxième turbine et permettant un passage d'eau de la deuxième turbine vers une ouverture dans le châssis flottant découverte par le deuxième position du volet, le dispositif de collecte étant en outre équipé de moyens d'alimentation et de moyens de commande pour commander au moins l'un parmi l'ouverture de collecte, le déplacement du dispositif de collecte, les première, deuxième et troisième turbines.The present invention therefore relates to a device for collecting floating waste on the surface of the water comprising a floating frame equipped with flotation means and having a collection opening formed at least in part under the waterline of the frame, the opening opening onto a waste inlet area formed in the floating frame, said waste inlet area being equipped with waste storage means inside the floating frame, the storage means being configured to allow a passage of water towards an outlet of the floating frame but retaining the floating waste, characterized in that the floating waste collection device further comprises a first turbine and a second turbine, mounted on the floating frame under the line of flotation downstream of the outlet of the floating frame to draw water from the collection opening towards the outlet to cause a corresponding displacement of the floating frame, u a third turbine mounted perpendicular to the first and second turbines to allow movement of the floating frame in a direction perpendicular to the flow of the fluid in the floating frame caused by the first and second turbines, and a movable flap associated with the second turbine, the shutter being mounted between the outlet and the second turbine such that in a first direction of rotation of the second turbine, the shutter is in a first position allowing water to pass from the outlet to the second turbine and in a second direction of rotation of the second turbine, the flap is in a second position preventing a passage of water between the outlet and the second turbine and allowing a passage water from the second turbine to an opening in the floating frame uncovered by the second position of the shutter, the collection device being further provided with supply means and control means for controlling at least one of the collecting opening, moving the collecting device, the first, second and third turbines.

Une telle configuration à deux turbines dont l'une est associée à un volet mobile d'un déflecteur conduit à une grande maniabilité du dispositif et permet de passer d'un fonctionnement en marche avant avec volet dans la première position (où la première turbine et la deuxième turbine, ou la première turbine seule, fonctionnent dans le même sens, à un mode marche arrière avec volet dans la seconde position (où la deuxième turbine inverse son sens de rotation), par exemple pour changer de direction ou se dégager aisément. Ainsi le dispositif peut fonctionner dans des zones encombrées comme des ports ou d'une superficie de balayage complexe.Such a configuration with two turbines, one of which is associated with a movable flap of a deflector, leads to great maneuverability of the device and makes it possible to pass from forward operation with flap in the first position (where the first turbine and the second turbine, or the first turbine alone, operate in the same direction, in a reverse mode with flap in the second position (where the second turbine reverses its direction of rotation), for example to change direction or easily disengage. Thus the device can operate in congested areas such as ports or complex scanning area.

En outre, le dispositif de collecte peut être configuré pour fonctionner de façon autonome.Furthermore, the collection device can be configured to operate autonomously.

La troisième turbine est disposée perpendiculairement aux première et deuxième turbines de sorte à fonctionner comme propulseur d'étrave. Une telle turbine bien connue de l'homme du métier permet des déplacements en rotation.The third turbine is arranged perpendicular to the first and second turbines so as to function as a bow thruster. Such a turbine, well known to those skilled in the art, allows movements in rotation.

Les moyens d'alimentation peuvent être une batterie, rechargeable par câble ou par l'intermédiaire de panneaux photovoltaïques disposés sur la face supérieure du châssis flottant.The power supply means can be a battery, rechargeable by cable or by means of photovoltaic panels arranged on the upper face of the floating frame.

Par ailleurs, par châssis, on entend toute structure creuse, ou partiellement, comme comprenant un assemblage de poutres, ou non comme un boîtier à parois pleines.Furthermore, by chassis is meant any hollow structure, or partially, such as comprising a assembly of beams, or not as a box with solid walls.

Selon un mode de réalisation de la présente invention, les moyens de stockage de déchets comprennent un filet amovible.According to an embodiment of the present invention, the waste storage means comprise a removable net.

Un tel filet, accessible via un capot mobile permet de vider le dispositif de collecte des déchets collectés.Such a net, accessible via a movable cover, makes it possible to empty the device for collecting the collected waste.

Selon un mode de réalisation de la présente invention, les moyens de stockage de déchets comprennent des moyens de filtration.According to an embodiment of the present invention, the waste storage means comprise filtration means.

De tels filtres sont particulièrement adaptés pour le nettoyage des zones polluées par des hydrocarbures, présents sous forme de nappes de surface, ou par des cyanobactéries par exemple.Such filters are particularly suitable for cleaning areas polluted by hydrocarbons, present in the form of surface slicks, or by cyanobacteria for example.

Selon un mode de réalisation de la présente invention, le dispositif comprend des moyens de mesure, connectés aux moyens de commande, et configurés pour mesurer au moins une propriété de l'eau.According to an embodiment of the present invention, the device comprises measuring means, connected to the control means, and configured to measure at least one property of the water.

De tels moyens de mesure permettent de collecter des données sur l'environnement dans lequel se déplace le dispositif de collecte. Ils permettent en outre par exemple de détecter la présence d'hydrocarbures de façon à adapter le fonctionnement du dispositif de collecte pour effectuer une dépollution spécifique.Such measurement means make it possible to collect data on the environment in which the collection device moves. They also make it possible, for example, to detect the presence of hydrocarbons so as to adapt the operation of the collection device to carry out specific depollution.

Selon un mode de réalisation de la présente invention, le dispositif comporte une plaque mobile de façon à faire varier la dimension de l'ouverture de collecte.According to an embodiment of the present invention, the device comprises a movable plate so as to vary the dimension of the collection opening.

Un tel agencement permet de réduire l'ouverture de collecte de façon à accélérer le flux d'eau aspirée.Such an arrangement makes it possible to reduce the collection opening so as to accelerate the flow of water drawn in.

Selon un mode de réalisation de la présente invention, le dispositif de collecte comporte en outre des bras s'étendant depuis l'ouverture de collecte vers l'extérieur et configurés pour guider les déchets flottants vers l'ouverture de collecte.According to an embodiment of the present invention, the collection device further comprises arms extending from the collection opening outward and configured to guide floating waste to the collection opening.

Selon un mode de réalisation de la présente invention, le dispositif comprend des moyens de positionnement.According to an embodiment of the present invention, the device comprises positioning means.

De tels moyens de positionnement, tels des systèmes de positionnement par satellites de type GPS, Galileo, GLONASS, permettent au dispositif de collecte de se repérer dans la zone où il doit intervenir et donc d'adapter son parcours selon les données GPS.Such positioning means, such as satellite positioning systems of the GPS, Galileo, GLONASS type, allow the collection device to identify itself in the zone where it must intervene and therefore to adapt its route according to the GPS data.

Sur la Figure 1, on peut voir que l'on a représenté un dispositif de collecte de déchets flottants 1 selon la présente invention. Par déchets flottants, on entend les déchets solides et les déchets liquides comme les hydrocarbures. Selon la présente invention, déchets et polluants sont synonymes.On the Figure 1 , it can be seen that there is shown a floating waste collection device 1 according to the present invention. Floating waste means solid waste and liquid waste such as hydrocarbons. According to the present invention, waste and pollutants are synonymous.

Le dispositif de collecte 1 est configuré pour flotter à la surface d'une étendue d'eau comme la mer ou un lac, voire une rivière. Le dispositif de collecte 1 comporte un châssis flottant 2. Le châssis flottant 2 est de forme sensiblement parallélépipédique et comprend deux bord longitudinaux 3, deux bords latéraux 4 qui définissent une paroi avant 5 et une paroi arrière 6. Par avant, on définit le côté dirigé vers le sens d'avancement du dispositif 1 pour la collecte des déchets flottants et par arrière, le côté opposé à celui-ci. Le sens d'avancement du dispositif 1 pour la collecte des déchets flottants est par la suite appelé marche avant et le sens opposé, marche arrière.The collection device 1 is configured to float on the surface of a body of water such as the sea or a lake, or even a river. The collection device 1 comprises a floating frame 2. The floating frame 2 is of substantially parallelepipedal shape and comprises two longitudinal edges 3, two side edges 4 which define a front wall 5 and a rear wall 6. By front, the side directed towards the direction of advancement of the device 1 for collecting floating waste and from behind, the side opposite it. The direction of advancement of the device 1 for the collection of floating waste is subsequently called forward and the opposite direction, reverse.

Le châssis flottant 2 comprend également une partie supérieure 7 et une partie inférieure 8.The floating frame 2 also comprises an upper part 7 and a lower part 8.

La châssis flottant 2 est équipé de flotteurs 9, chacun disposé le long des bords longitudinaux 3.The floating frame 2 is equipped with floats 9, each arranged along the longitudinal edges 3.

De façon connue de l'homme du métier, les flotteurs 9 sont configurés pour maintenir le dispositif de collecte 1 à la surface de l'eau, avec une partie immergé, soit au-dessous de sa ligne de flottaison L, et une partie émergée, soit au-dessus de sa ligne de flottaison L, tel qu'on peut le voir sur les Figures 2-3 et 5-6. De façon préférentielle, les flotteurs 9 sont remplis d'une mousse expansive de façon à rendre le dispositif de collecte 1 insubmersible.In a manner known to those skilled in the art, the floats 9 are configured to maintain the collection device 1 at the surface of the water, with a submerged part, i.e. below its waterline L, and an emerged part , either above its waterline L, as can be seen on the Figures 2-3 and 5-6 . Preferably, the floats 9 are filled with an expanding foam so as to make the collection device 1 unsinkable.

Comme on peut le voir sur la Figure 1, la partie supérieure 7 est équipée d'un capot 10 pivotant. Le capot 10 est configuré pour ouvrir/fermer le châssis 2 de façon à pouvoir accéder à/isoler l'espace intérieur 11 du châssis flottant 2.As can be seen on the Figure 1 , the upper part 7 is equipped with a cover 10 pivoting. The cover 10 is configured to open/close the frame 2 so as to be able to access/isolate the interior space 11 from the floating frame 2.

Au niveau de la partie inférieure 8, le châssis flottant 2 se prolonge par un boîtier 12 disposé entre les flotteurs 9 et disposé entièrement au-dessous de la ligne de flottaison L. Le boîtier 12 est de forme sensiblement parallélépipédique et comporte une paroi avant 13, une paroi arrière 14, des parois longitudinales 15, une partie supérieure 16 en communication avec l'espace intérieur 11 du châssis flottant 2 et un fond 17.At the level of the lower part 8, the floating frame 2 is extended by a casing 12 disposed between the floats 9 and disposed entirely below the waterline L. The casing 12 is of substantially parallelepipedal shape and comprises a front wall 13 , a rear wall 14, longitudinal walls 15, an upper part 16 in communication with the interior space 11 of the floating frame 2 and a bottom 17.

Le dispositif de collecte 1 présente ainsi en allant du capot 10 au fond 17 du boîtier 12 un espace creux, comprenant l'espace intérieur 11 du châssis flottant 2, situé au-dessus de la ligne de flottaison L, et l'espace interne 18 du boîtier 12, avec une partie située au-dessus de la ligne de flottaison L et une partie située au-dessous de la ligne de flottaison L.The collection device 1 thus has, going from the cover 10 to the bottom 17 of the casing 12, a hollow space, comprising the interior space 11 of the floating frame 2, located above the waterline L, and the internal space 18 of the housing 12, with a part located above the waterline L and a part located below the waterline L.

Le dispositif de collecte 1 comprend également des moyens d'alimentation 19. Les moyens d'alimentation 19 comprennent des panneaux photovoltaïques 20 disposés sur la face externe 21 du capot 10 et un régulateur associé 22 bien connu de l'homme du métier disposé sur la face interne 23 du capot 10. Par ailleurs, les moyens d'alimentation 19 comprennent des batteries rechargeables 24 pour le stockage de l'énergie collectée par les panneaux photovoltaïques 20. De façon avantageuse, les batteries sont disposées à l'intérieur des flotteurs 9. Les batteries 24 pourront être rechargeables par câble.The collection device 1 also comprises supply means 19. The supply means 19 comprise photovoltaic panels 20 arranged on the external face 21 of the cover 10 and an associated regulator 22 well known to those skilled in the art arranged on the internal face 23 of the cover 10. Furthermore, the supply means 19 comprise rechargeable batteries 24 for storing the energy collected by the photovoltaic panels 20. Advantageously, the batteries are arranged inside the floats 9 The batteries 24 can be rechargeable by cable.

Le dispositif de collecte 1 comprend des moyens de commande 25 configurés pour piloter le dispositif de collecte 1 et connectés aux moyens d'alimentation 19. De façon connue, les moyens de commande 25 comprennent une carte électronique équipée d'un moyen de traitement de données type processeur, microprocesseur, microcontrôleur, dispositif numérique de traitement de données, matrice prédiffusée programmable (FPGA), composant à application spécifique (ASIC), associé à ou intégrant une mémoire de type mémoire morte (ROM), ou vive (RAM) (non représentés). De façon avantageuse, les moyens de commande 25 sont disposés sur la face interne 23 du capot 10.The collection device 1 comprises control means 25 configured to control the collection device 1 and connected to the power supply means 19. In known manner, the control means 25 comprise an electronic card equipped with a data processing means type processor, microprocessor, microcontroller, digital data processing device, programmable gate array (FPGA), application-specific component (ASIC), associated with or integrating a memory of the read only memory (ROM) or random access (RAM) type (not represented). Advantageously, the control means 25 are arranged on the internal face 23 of the cover 10.

Il est bien entendu que le positionnement du régulateur 22 et des moyens de commande 25 est donné à titre indicatif et qu'ils peuvent être disposés ailleurs dans le dispositif de collecte 1 sans s'écarter du cadre de la présente invention.It is understood that the positioning of the regulator 22 and of the control means 25 is given by way of indication and that they can be arranged elsewhere in the collection device 1 without departing from the scope of the present invention.

Les moyens de commande 25 comprennent en outre des moyens de communication à distance (non représentés) et des moyens de positionnement, comme par exemple GPS, Galileo, GLONASS. De tels moyens de positionnement doivent permettre au dispositif 1 de se repérer et d'adapter son parcours. De tels moyens de communication à distance sont configurés pour délivrer à l'extérieur des informations provenant du dispositif de collecte 1 ou charger dans la mémoire des informations provenant de l'extérieur, comme par exemple une carte et un parcours. Par ailleurs, les moyens de communication à distance peuvent permettre de piloter à distance le dispositif de collecte 1.The control means 25 also comprise remote communication means (not shown) and positioning means, such as for example GPS, Galileo, GLONASS. Such positioning means must enable the device 1 to locate itself and to adapt its journey. Such remote communication means are configured to deliver information from the collection device 1 to the outside or to load information from the outside into the memory, such as for example a map and a route. Furthermore, the remote communication means can make it possible to remotely control the collection device 1.

Ainsi, le dispositif de collecte 1 est configuré pour fonctionner, par l'intermédiaire des moyens de commande 25, soit de manière autonome sur la base d'un parcours préprogrammé, soit de façon télécommandée par un opérateur à distance, par exemple au moyen d'un dispositif radiocommandé connecté aux moyens de commande 25.Thus, the collection device 1 is configured to operate, via the control means 25, either autonomously on the basis of a preprogrammed route, or remotely controlled by a remote operator, for example by means of a radio-controlled device connected to the control means 25.

Le dispositif de collecte 1 peut également comprendre des capteurs (infrarouge, ultrasons, capteurs d'image de type CCD ou analogues) associés à des moyens de traitement en temps réel et facultativement à des outils de positionnement type GPS ou analogues, pour analyser son environnement en temps réel et adapter son parcours par exemple en cas d'identification, par l'intermédiaire des capteurs, d'obstacles sur le parcours du dispositif de collecte 1.The collection device 1 can also comprise sensors (infrared, ultrasound, CCD type image sensors or the like) associated with real-time processing means and optionally with GPS type positioning tools or the like, to analyze its environment. in real time and adapt its route, for example in the event of identification, via the sensors, of obstacles in the route of the collection device 1.

Le dispositif de collecte 1 comprend des moyens de collecte 26. Comme on peut le voir sur la Figure 4, les moyens de collecte 26 sont équipés de bras 27 s'étendant depuis la paroi avant 5 du châssis flottant 2 vers l'extérieur. De façon préférentielle, les bras 27 sont constitués chacun par une plaque verticale 27. Les plaques sont disposées au niveau de la ligne de flottaison L et orientées l'une par rapport à l'autre de façon à former un entonnoir vers l'ouverture de collecte formée à l'avant du châssis flottant 2. Une telle orientation facilite la collecte des déchets, en particulier les déchets solides, qui lors du fonctionnement du dispositif de collecte 1 en marche avant sont amenés à converger vers le châssis flottant 2. De façon avantageuse, les bras 27 sont reliés de façon pivotante à la paroi avant 5 du châssis flottant 2, par exemple au moyen d'une charnière réglable 28 de façon à ajuster l'orientation des bras 27 l'un par rapport à l'autre. Un tel ajustement peut être commandé par les moyens de commande 25.The collecting device 1 comprises collecting means 26. As can be seen in the Figure 4 , the collection means 26 are equipped with arms 27 extending from the front wall 5 of the floating frame 2 outwards. Preferably, the arms 27 are each constituted by a vertical plate 27. The plates are arranged at the level of the waterline L and oriented with respect to each other so as to form a funnel towards the opening of collection formed at the front of the floating frame 2. Such an orientation facilitates the collection of waste, in particular solid waste, which during the operation of the collecting device 1 in forward motion are caused to converge towards the floating frame 2. Advantageously, the arms 27 are pivotally connected to the front wall 5 of the floating frame 2, for example by means of an adjustable hinge 28 so as to adjust the orientation of the arms 27 relative to each other. Such an adjustment can be controlled by the control means 25.

Le châssis flottant 2 comporte au niveau de la paroi avant 5 une zone d'admission 29. La zone d'admission 29 est configurée pour introduire les déchets flottants collectés dans le dispositif de collecte 1.The floating frame 2 comprises at the level of the front wall 5 an admission zone 29. The admission zone 29 is configured to introduce the floating waste collected into the collection device 1.

La zone d'admission 29 comporte une ouverture de collecte 30 de forme sensiblement rectangulaire pratiquée dans la paroi avant 5 du châssis flottant 2 et configurée de façon à faire communiquer l'espace interne 18 du châssis flottant 2 avec l'extérieur au niveau de la ligne de flottaison L. L'ouverture 30 comporte également un bord supérieur 31 situé au-dessus de la ligne de flottaison L et un bord inférieur 32 situé au-dessous de la ligne de flottaison L.The admission zone 29 comprises a collection opening 30 of substantially rectangular shape made in the front wall 5 of the floating frame 2 and configured so as to cause the internal space 18 of the floating frame 2 to communicate with the outside at the level of the waterline L. The opening 30 also has an upper edge 31 located above the waterline L and a lower edge 32 located below the waterline L.

Comme on peut le voir sur la Figure 4, les bras 27 sont reliés au châssis flottant 2 au niveau des bords latéraux 33 de l'ouverture 30 de sorte que les déchets collectés par les bras 27 convergent vers l'ouverture 30 de façon à être introduits dans l'espace interne 18 du châssis flottant 2. Une telle configuration permet aux bras 27 de guider les déchets flottants vers la zone d'admission 29.As can be seen on the Figure 4 , the arms 27 are connected to the floating frame 2 at the side edges 33 of the opening 30 so that the waste collected by the arms 27 converges towards the opening 30 so as to be introduced into the internal space 18 of the frame floating 2. Such a configuration allows the arms 27 to guide the floating waste towards the intake zone 29.

La zone d'admission 29 comporte également une plaque mobile 34 agencée à l'intérieur du châssis flottant 2 le long de la paroi avant 5. La plaque mobile 34 présente une largeur au moins égale à celle de l'ouverture 30. La plaque mobile 34 est configurée de façon à monter ou descendre de façon à amener le bord supérieur 35 de la plaque mobile 34 au-dessus du bord inférieur 32 de l'ouverture 30 pour obturer partiellement la partie inférieure de l'ouverture 30. Ainsi, l'écart entre le bord supérieur 35 et la ligne de flottaison L peut être réduit. Comme expliqué par la suite, le flux d'eau aspiré peut être accéléré.The admission zone 29 also includes a movable plate 34 arranged inside the floating frame 2 along the front wall 5. The movable plate 34 has a width at least equal to that of the opening 30. The movable plate 34 is configured to mount or descend so as to bring the upper edge 35 of the movable plate 34 above the lower edge 32 of the opening 30 to partially close the lower part of the opening 30. Thus, the gap between the upper edge 35 and the waterline L can be reduced. As explained below, the flow of water sucked in can be accelerated.

Selon un mode de réalisation préféré, la largeur de l'ouverture 30 est comprise entre 7 et 12 cm.According to a preferred embodiment, the width of the opening 30 is between 7 and 12 cm.

Les moyens de collecte 26 comprennent également des moyens de stockage des déchets solides 36. Selon le mode de réalisation représenté sur les Figures 5-6, un filet 36 est employé. Le filet 36 est dans l'espace interne 18 du boîtier 12. Le filet 36 est fixé de façon amovible au châssis flottant 2 par l'intermédiaire de moyens de fixation amovible 37, par exemple boutons pressions, fermeture à glissière, bandes à boucles et crochets. Il convient de noter que tous types de moyens de fixation amovible 37 connus de l'homme du métier pourront être employés. Le filet 36 comporte une ouverture 38 disposée en correspondance et raccordée à l'ouverture 30 du châssis flottant 2. Ainsi, les déchets collectés passant par l'ouverture 30 sont conduits dans le filet 36 et les déchets solides sont retenus par les mailles 39 du filet 36. L'homme du métier saura déterminer le maillage adapté. En outre, de manière avantageuse, le filet 36 est lesté par un poids (non représenté).The collection means 26 also include solid waste storage means 36. According to the embodiment shown in the Figures 5-6 , a net 36 is used. The net 36 is in the internal space 18 of the housing 12. The net 36 is removably fixed to the floating frame 2 by means of removable fixing means 37, for example press studs, zipper, buckle bands and hooks. It should be noted that all types of removable fastening means 37 known to those skilled in the art may be used. The net 36 comprises an opening 38 arranged in correspondence and connected to the opening 30 of the floating frame 2. Thus, the waste collected passing through the opening 30 is led into the net 36 and the solid waste is retained by the meshes 39 of the net 36. A person skilled in the art will be able to determine the appropriate mesh. In addition, advantageously, the net 36 is ballasted by a weight (not shown).

Il convient de noter que d'autres moyens appropriés peuvent être envisagés par l'homme du métier sans s'écarter de la présente invention, comme un casier présentant un ouverture principale comme l'ouverture 38 et des ouvertures secondaires analogues au maillage 39 du filet 36, pour autant qu'ils autorisent l'entrée de l'eau et des déchets collectés par l'intermédiaire de l'ouverture 30 du châssis flottant 2 et retiennent les déchets solides tout en laissant passer l'eau et les déchets liquides.It should be noted that other appropriate means can be envisaged by those skilled in the art without departing from the present invention, such as a locker having a main opening like the opening 38 and secondary openings similar to the mesh 39 of the net 36, as long as they allow the entry of water and waste collected through the opening 30 of the floating frame 2 and retain solid waste while allowing water and liquid waste to pass.

Selon le mode de réalisation représenté sur Figures 5-6, les moyens de collecte 26 comprennent des moyens de stockage de déchets liquides 40 comportant des moyens de filtration 40. Les moyens de filtration sont configurés pour filtrer l'eau collectée et retenir et/ou traiter les déchets liquides tels que les hydrocarbures. En outre, les moyens de filtration pourront être configurés pour le traitement des cyanobactéries. Pour ce faire, les moyens de filtration 40 comprennent un logement 41 apte à recevoir au moins un filtre 42. Le logement comporte une entrée 43 disposée côté intérieur du châssis flottant 2 et une sortie 44. Les moyens de filtration 40 sont disposés en aval du filet 36.According to the embodiment shown in Figures 5-6 , the collection means 26 comprise liquid waste storage means 40 comprising filtration means 40. The filtration means are configured to filter the collected water and retain and/or treat liquid waste such as hydrocarbons. In addition, the filtration means may be configured for the treatment of cyanobacteria. To do this, the filtration means 40 comprise a housing 41 capable of receiving at least one filter 42. The housing comprises an inlet 43 arranged on the inside of the floating frame 2 and an outlet 44. The filtration means 40 are arranged downstream of the fillet 36.

Le dispositif de collecte 1 comprend des moyens de propulsion 45. De façon connue, les moyens de propulsion 45 sont configurés pour déplacer le dispositif de collecte 1.The collection device 1 comprises propulsion means 45. In known manner, the propulsion means 45 are configured to move the collection device 1.

Les moyens de propulsion 45 comprennent une première turbine 46. La première turbine 46 est reçue dans une logement 47 sensiblement cylindrique ayant une entrée 48 et une sortie 49. Comme on peut le voir sur les Figures 5-6, l'entrée est disposée côté intérieur du châssis 2. Sur ce mode de réalisation, l'entrée 48 du logement 47 de la première turbine 46 est raccordée à la sortie 44 du logement 41 des moyens de filtration 40.The propulsion means 45 comprise a first turbine 46. The first turbine 46 is received in a substantially cylindrical housing 47 having an inlet 48 and an outlet 49. As can be seen in the Figures 5-6 , the inlet is arranged on the inside of the frame 2. In this embodiment, the inlet 48 of the housing 47 of the first turbine 46 is connected to the outlet 44 of the housing 41 of the filtration means 40.

Comme on peut le voir sur la Figure 1, la sortie 49 du logement 47 de la première turbine 46 est raccordée à un orifice 50 ménagé dans la paroi arrière 14 du boîtier 12.As can be seen on the Figure 1 , the outlet 49 of the housing 47 of the first turbine 46 is connected to an orifice 50 made in the rear wall 14 of the housing 12.

Dans un mode marche avant, la première turbine 46 aspire l'eau contenue dans l'espace interne 18 du châssis flottant 2, qui y est entrée sous l'effet de l'aspiration, par l'intermédiaire de l'ouverture 30 de la paroi avant 5. L'eau expulsée par l'orifice 50 conduit à la propulsion du dispositif de collecte 1 vers l'avant.In a forward mode, the first turbine 46 draws in the water contained in the internal space 18 of the floating frame 2, which has entered there under the effect of the suction, via the opening 30 of the front wall 5. The water expelled through the orifice 50 leads to the propulsion of the collection device 1 forwards.

En outre, du fait du positionnement du filet 36 et des moyens de filtration 40 entre la zone d'admission 29 et la première turbine 46, les déchets aspirés avec le flux d'eau sont piégés dans ceux-ci. La première turbine 46 présente donc une double fonction de propulsion et aspiration de déchets.In addition, due to the positioning of the net 36 and the filtration means 40 between the inlet zone 29 and the first turbine 46, the waste sucked up with the flow of water is trapped therein. The first turbine 46 therefore has a dual function of propulsion and suction of waste.

Par ailleurs, le flux d'eau aspiré peut être accéléré en remontant la plaque mobile 34 de sorte à réduire la distance entre la surface de l'eau et le bord supérieur 35 de la plaque mobile 34. De préférence, la distance entre la ligne de flottaison L et la limite inférieure 32, 35 de l'ouverture 30 est comprise entre 2 et 10 cm, de manière particulièrement préférée de 5 cm.Furthermore, the flow of water drawn in can be accelerated by raising the movable plate 34 so as to reduce the distance between the surface of the water and the upper edge 35 of the movable plate 34. Preferably, the distance between the line flotation L and the lower limit 32, 35 of the opening 30 is between 2 and 10 cm, particularly preferably 5 cm.

La première turbine 46 fonctionne toujours selon le même sens de rotation de sorte à aspirer de l'eau en continu. Du fait du positionnement des moyens de filtration 40 en amont de la première turbine 46, l'eau aspirée par la première turbine 46 filtre les polluants liquides comme les hydrocarbures.The first turbine 46 always operates in the same direction of rotation so as to suck in water continuously. Due to the positioning of the filtration means 40 upstream of the first turbine 46, the water sucked in by the first turbine 46 filters liquid pollutants such as hydrocarbons.

Les moyens de propulsion 45 comprennent également une deuxième turbine 51. La deuxième turbine 51 est reçue dans un logement 52 sensiblement cylindrique ayant un premier orifice 53 et un second orifice 54. Comme on peut le voir sur les Figures 5-6, le premier orifice 53 est disposé côté intérieur du châssis 2. Comme on peut le voir sur la Figure 1, le second orifice 54 du logement 52 de la deuxième turbine 51 est raccordé à un orifice 55 ménagé dans la paroi arrière 14 du boîtier 12.The propulsion means 45 also comprise a second turbine 51. The second turbine 51 is received in a substantially cylindrical housing 52 having a first orifice 53 and a second orifice 54. As can be seen in the Figures 5-6 , the first orifice 53 is arranged on the inside of the chassis 2. As can be seen in the Figure 1 , the second orifice 54 of the housing 52 of the second turbine 51 is connected to an orifice 55 provided in the rear wall 14 of the housing 12.

Les première 46 et deuxième 51 turbines sont agencées parallèles l'une à l'autre, horizontales et sont contenues dans un plan médian longitudinal du dispositif de collecte 1 de façon à déplacer le dispositif de collecte 1 de façon rectiligne. Les première 46 et deuxième 51 turbines sont disposées au niveau de l'arrière du châssis 2, la première turbine 46 au-dessus de la deuxième turbine 51.The first 46 and second 51 turbines are arranged parallel to each other, horizontal and are contained in a longitudinal median plane of the collection device 1 so as to move the collection device 1 in a straight line. The first 46 and second 51 turbines are arranged at the rear of the frame 2, the first turbine 46 above the second turbine 51.

En amont de la deuxième turbine 51 est disposé un déflecteur 56. Le déflecteur 56 se présente sous la forme d'un conduit en forme de À avec un conduit primaire 57 cylindrique avec un premier orifice 58 et un second orifice 59. Comme on peut le voir sur les Figures 5-6, le premier orifice 58 du conduit primaire 57 est disposé côté intérieur du châssis 2 et le second orifice 59 du conduit primaire 57 est raccordé au premier orifice 53 de la deuxième turbine 51.Upstream of the second turbine 51 is arranged a deflector 56. The deflector 56 is in the form of an A-shaped duct with a cylindrical primary duct 57 with a first orifice 58 and a second orifice 59. As can be seen see on the Figures 5-6 , the first orifice 58 of the primary duct 57 is arranged on the inside of the frame 2 and the second orifice 59 of the primary duct 57 is connected to the first orifice 53 of the second turbine 51.

Le déflecteur 56 comporte également un conduit secondaire 60 cylindrique ayant un premier orifice 61 et un second orifice 62. Comme on peut le voir sur les Figures 5-6, le premier orifice 61 du conduit secondaire 60 est raccordé à un orifice 63 ménagé dans le fond 17 du boîtier 12. Le second orifice 62 du conduit secondaire 60 est raccordé au niveau d'une zone intermédiaire du conduit secondaire de façon à faire communiquer le conduit primaire 57 et le conduit secondaire 60. Le conduit secondaire 60 est agencé incliné par rapport au conduit primaire 57, orienté depuis le conduit primaire 57 vers l'avant et vers le fond 17 du boîtier 12. De préférence, le conduit primaire 57 est agencé horizontalement, parallèle au fond 17 du boîtier 12. Le conduit primaire 57 et le conduit secondaire 60 ont même diamètre.The deflector 56 also comprises a cylindrical secondary duct 60 having a first orifice 61 and a second orifice 62. As can be seen in the Figures 5-6 , the first orifice 61 of the secondary duct 60 is connected to an orifice 63 made in the bottom 17 of the housing 12. The second orifice 62 of the secondary duct 60 is connected at the level of an intermediate zone of the secondary duct so as to communicate the primary duct 57 and secondary duct 60. Secondary duct 60 is arranged inclined relative to primary duct 57, oriented from primary duct 57 forward and towards bottom 17 of housing 12. Preferably, primary duct 57 is arranged horizontally, parallel to the bottom 17 of the housing 12. The primary conduit 57 and the secondary conduit 60 have the same diameter.

Le déflecteur 56 comprend en outre un volet mobile 64. Le volet 64 est relié de manière pivotante, par exemple par l'intermédiaire d'une charnière 65 au conduit primaire 57, au niveau de la jonction entre le conduit primaire 57 et le conduit secondaire 60 la plus vers le premier orifice 58 du conduit primaire 57, soit la plus éloignée de la deuxième turbine 51. Le volet 64 comporte en partant du conduit primaire 57 un premier segment 66, un deuxième segment 67 et un troisième segment 68 successifs. Le premier segment 66 est dimensionné de façon à obturer complètement, et de façon hermétique, le second orifice 62 du conduit secondaire 60. Le deuxième segment 67 est incliné par rapport au premier segment 66 vers la deuxième turbine 51. Et le troisième segment 68 est sensiblement parallèle au premier segment 66 et s'étend depuis le sommet du deuxième segment toujours en direction de la deuxième turbine 51 de telle sorte qu'un flux de fluide provenant de la deuxième turbine 51 va entrer en contact avec les deuxième 67 et troisième 68 segments pour soulever le volet 64 afin qu'il obture le conduit primaire 57.The deflector 56 further comprises a movable flap 64. The flap 64 is pivotally connected, for example via a hinge 65 to the primary duct 57, at the junction between the primary duct 57 and the secondary duct 60 the furthest towards the first orifice 58 of the primary duct 57, ie the furthest from the second turbine 51. The flap 64 comprises, starting from the primary duct 57, a first segment 66, a second segment 67 and a third segment 68 in succession. The first segment 66 is dimensioned so as to completely and hermetically close the second orifice 62 of the secondary duct 60. The second segment 67 is inclined with respect to the first segment 66 towards the second turbine 51. And the third segment 68 is substantially parallel to the first segment 66 and extends from the top of the second segment always in the direction of the second turbine 51 such that a flow of fluid coming from the second turbine 51 will come into contact with the second 67 and third 68 segments to lift the flap 64 so that it closes the primary duct 57.

Le volet 64 peut être réalisé en acier inoxydable, de façon préférentielle en aluminium.The flap 64 can be made of stainless steel, preferably aluminum.

Le volet 64 est configuré de façon à pouvoir pivoter entre une première position abaissée et une seconde position relevée. Dans la première position, le premier segment 66 obture complétement le second orifice 62 du conduit secondaire 60 et les deuxième 67 et troisième 68 segments laissent le conduit principal 57 libre sur les deux tiers de son diamètre, comme on peut le voir sur la Figure 5. Dans la seconde position, le troisième segment 68 est au contact du conduit primaire 57 et ainsi le volet 64 obture complétement le premier orifice 58 du conduit primaire 57, le second orifice 62 du conduit secondaire 60 étant complétement ouvert.The flap 64 is configured so as to be able to pivot between a first lowered position and a second raised position. In the first position, the first segment 66 completely closes off the second orifice 62 of the secondary duct 60 and the second 67 and third 68 segments leave the main duct 57 free over two thirds of its diameter, as can be seen on the Figure 5 . In the second position, the third segment 68 is in contact with the primary duct 57 and thus the flap 64 completely closes the first orifice 58 of the primary duct 57, the second orifice 62 of the secondary duct 60 being completely open.

Dans le mode marche avant, la deuxième turbine 51 fonctionne dans le même sens que la première turbine 57 et aspire l'eau contenue dans l'espace interne 18 du boîtier 12, à travers le filet 36. Le volet 64 étant dans la position abaissée, l'eau est conduite du premier orifice 58 du conduit principal 57, dans le conduit principal 57 et dans le logement 52 de la deuxième turbine 51 pour être évacuée par le second orifice 54 du logement 52 de la deuxième turbine 51 et l'orifice 55 du boîtier 12. Selon un mode de réalisation non représenté, des moyens de filtration sont disposés en amont du déflecteur 56.In the forward mode, the second turbine 51 operates in the same direction as the first turbine 57 and sucks the water contained in the internal space 18 of the housing 12, through the net 36. The flap 64 being in the lowered position , the water is led from the first orifice 58 of the main duct 57, into the main duct 57 and into the housing 52 of the second turbine 51 to be discharged through the second orifice 54 of the housing 52 of the second turbine 51 and the orifice 55 of the housing 12. According to an embodiment not shown, filtration means are arranged upstream of the deflector 56.

Par ailleurs, dans le mode marche avant, il est envisageable que seule la première turbine 46 fonctionne, assurant ainsi à elle seule d'une part la propulsion du dispositif de collecte 1 vers l'avant et, d'autre part, la collecte et le stockage des déchets solides et la collecte et la filtration des déchets liquides.Moreover, in the forward mode, it is conceivable that only the first turbine 46 operates, thus ensuring by itself on the one hand the propulsion of the collection device 1 forwards and, on the other hand, the collection and storage of solid waste and collection and filtration of liquid waste.

Dans le mode marche arrière, la deuxième turbine 51 fonctionne dans le sens opposé et aspire de l'eau par l'intermédiaire de l'orifice 55 du boîtier 12. L'eau traverse le second orifice 54 du logement 52 de la deuxième turbine 51, le logement 52 de la deuxième turbine 51 et le premier orifice 53 du logement 52 de la deuxième turbine 51. L'eau propulsée exerce une pression sur les deuxième 67 et troisième 68 segments du volet 64 de façon à le soulever et le positionner en obturation du premier orifice 58 du conduit primaire 57. La force exercée par l'eau propulsée maintient le volet 64 dans cette position. L'eau est ainsi conduite dans le conduit secondaire 60 et est évacuée par le premier orifice 61 du conduit secondaire 60 et l'orifice 63 du fond 17 du boîtier 12. Du fait de l'inclinaison du conduit secondaire 60 par rapport au fond 17 du boîtier 12, l'eau est propulsée vers le bas et vers l'avant de façon à propulser le dispositif de collecte 1 vers l'arrière.In the reverse mode, the second turbine 51 operates in the opposite direction and draws water through the orifice 55 of the housing 12. The water passes through the second orifice 54 of the housing 52 of the second turbine 51 , the housing 52 of the second turbine 51 and the first orifice 53 of the housing 52 of the second turbine 51. The propelled water exerts pressure on the second 67 and third 68 segments of the shutter 64 so as to lift it and position it in closing of the first orifice 58 of the primary duct 57. The force exerted by the propelled water maintains the flap 64 in this position. The water is thus led into the secondary conduit 60 and is evacuated through the first orifice 61 of the secondary conduit 60 and the orifice 63 of the bottom 17 of the casing 12. Due to the inclination of the secondary duct 60 with respect to the bottom 17 of the casing 12, the water is propelled downwards and forwards so as to propel the collection device 1 towards the back.

Dans le mode marche arrière, la première turbine 51 fonctionne à vitesse minimale de façon d'une part à ne pas s'opposer à la propulsion vers l'arrière et d'autre part à maintenir une aspiration des déchets collectés pour éviter leur relargage par l'ouverture 30. Il est également possible d'arrêter la première turbine 46 pour le mode marche arrière. De façon générale, il suffit que la vitesse de la deuxième turbine 51 soit supérieure à celle de la première turbine 46.In the reverse mode, the first turbine 51 operates at minimum speed so as on the one hand not to oppose the rearward propulsion and on the other hand to maintain suction of the collected waste to avoid their release by the opening 30. It is also possible to stop the first turbine 46 for the reverse mode. In general, it suffices for the speed of the second turbine 51 to be greater than that of the first turbine 46.

Dans le mode marche arrière, la propulsion du dispositif de collecte 1 est assurée par la deuxième turbine 51.In the reverse mode, the propulsion of the collection device 1 is ensured by the second turbine 51.

Les première 46 et deuxième 51 turbines sont commandées par les moyens de commande 25.The first 46 and second 51 turbines are controlled by the control means 25.

Les moyens de propulsion 45 comprennent également une troisième turbine 69. La troisième turbine 69 est agencée perpendiculairement aux première 46 et deuxième 51 turbines et est disposée au niveau de l'avant du boîtier 12. La troisième turbine 69 est reçue dans une logement 70 sensiblement cylindrique, isolé vis-à-vis de l'intérieur du boîtier 12, et ayant deux orifices 71, chacun ménagé dans les parois longitudinales 15 du boîtier 12, comme on peut le voir sur les Figures 2 et 5-6. La troisième turbine 69 est configurée pour fonctionner selon deux sens de rotation et, seule ou en combinaison avec les première 46 et seconde 51 turbines, pour faire tourner le dispositif de collecte 1. La troisième turbine 69 fonctionne en tant que propulseur d'étrave.The propulsion means 45 also comprise a third turbine 69. The third turbine 69 is arranged perpendicular to the first 46 and second 51 turbines and is arranged at the level of the front of the housing 12. The third turbine 69 is received in a housing 70 substantially cylindrical, insulated vis-à-vis the interior of the casing 12, and having two orifices 71, each provided in the longitudinal walls 15 of the casing 12, as can be seen in the Figure 2 and 5-6 . The third turbine 69 is configured to operate in two directions of rotation and, alone or in combination with the first 46 and second 51 turbines, to rotate the collection device 1. The third turbine 69 functions as a bow thruster.

Le dispositif de collecte 1 est équipé de moyens de mesure 72. Comme on peut le voir sur la Figure 1, les moyens de mesure comprennent un boîtier 73 cylindrique disposé à l'arrière du dispositif de collecte 1. Comme on peut le voir sur les Figures 5-6, le boîtier 73 est partiellement immergé sous la ligne de flottaison L. Le boîtier 73 est configuré pour recevoir en son sein une pluralités de sondes de mesure 74. Ces sondes de mesure 74 bien connues de l'homme du métier sont choisies parmi, mais sans y être limité, des sondes de mesure de conductivité, pH, redox, chlorophylle a, hydrocarbures. D'autres types de sondes de mesure pourront être envisagées par l'homme du métier sans s'écarter du cadre de la présente invention. De préférence, le logement 70 est dimensionné pour recevoir six sondes de mesure 74.The collection device 1 is equipped with measuring means 72. As can be seen in the Figure 1 , the measurement means comprise a cylindrical casing 73 disposed at the rear of the collection device 1. As can be seen in the Figures 5-6 , the housing 73 is partially submerged below the waterline L. The housing 73 is configured to receive within it a plurality of measurement probes 74. These measurement probes 74 well known to those skilled in the art are chosen from, but without being limited thereto, probes for measuring conductivity, pH, redox, chlorophyll a, hydrocarbons. Other types of measurement probes may be envisaged by those skilled in the art without departing from the scope of the present invention. Preferably, the housing 70 is sized to receive six measurement probes 74.

Selon un autre mode de réalisation, non représenté, les moyens de mesure 72 sont disposés au niveau des flotteurs 9.According to another embodiment, not shown, the measuring means 72 are arranged at the level of the floats 9.

Les sondes de mesure sont en contact avec l'eau par l'intermédiaire d'ouvertures 75 ménagées dans la paroi du boîtier 73. En outre, les sondes sont connectées aux moyens de commande 25 de façon à analyser différentes propriétés de l'eau comme la qualité de l'eau et la présence de certains polluants comme les hydrocarbures. Les sondes de mesure 74 peuvent également comprendre des capteurs de mesure de profondeur.The measurement probes are in contact with the water via openings 75 made in the wall of the housing 73. In addition, the probes are connected to the control means 25 so as to analyze various properties of the water such as water quality and the presence of certain pollutants such as hydrocarbons. Measurement probes 74 may also include depth measurement sensors.

Selon un mode de réalisation, non représenté, le dispositif de collecte 1 comprend des capteurs de distance, par exemple à ultrasons. De manière avantageuse, le dispositif de collecte 1 comprend huit capteurs répartis selon trois capteurs à l'avant et à l'arrière et deux sur les côtés.According to one embodiment, not shown, the collection device 1 comprises distance sensors, for example ultrasonic. Advantageously, the collection device 1 comprises eight sensors distributed according to three sensors at the front and at the rear and two on the sides.

Les capteurs de distance sont connectés aux moyens de commande 25 de façon à commander le déplacement du dispositif de collecte 1 en fonction des obstacles détectés par les capteurs de distance.The distance sensors are connected to the control means 25 so as to control the movement of the collection device 1 according to the obstacles detected by the distance sensors.

De façon avantageuse, le dispositif de collecte 1 se déplace à une vitesse de 2,5 à 3 nœuds.Advantageously, the collecting device 1 moves at a speed of 2.5 to 3 knots.

Selon un mode de réalisation préféré, les dimensions du dispositif de collecte 1 sont de 1600*90 mm et le tirant d'eau est de 250 mm.According to a preferred embodiment, the dimensions of the collection device 1 are 1600*90 mm and the draft is 250 mm.

En variante, le dispositif de collecte 1 peut être dimensionné pour des zones réduites telles que les ports et les zones aquatiques encombrées, des zones de grande superficie ou encore les zones côtières et hauturières.As a variant, the collection device 1 can be sized for small areas such as ports and congested aquatic areas, large areas or even coastal and offshore areas.

Nous allons maintenant indiquer un cycle de fonctionnement à titre d'exemple uniquement. D'autres cycles de fonctionnement pourront être envisagés par l'homme du métier suivant les circonstances, en particulier en fonction de la configuration de la zone de fonctionnement ou de la nature des déchets à collecter. Le dispositif de collecte 1 fonction en marche avant, avec les première 46 et deuxième 51 turbines fonctionnant dans le même sens de rotation. Selon un algorithme préprogrammé dans la mémoire, le dispositif de collecte se déplace sur la superficie de la zone à balayer, puis se déplace sur toute la surface par des mouvements d'allers et retours parallèles. Dans cette étape, les capteurs de distance indiquent une limite matérielle, par exemple une jetée dans un port. Le dispositif de collecte fait demi-tour et se décale grâce aux deuxième 51 et troisième 69 turbines. Une fois toute la surface prédéfinie balayée, le dispositif de collecte effectue un dernier passage sur la périphérie. Ceci peut également être commandé selon un horloge, par exemple toutes les 30 min ou toutes les heures. Il est bien entendu que les limites de la superficie à balayer pourront être préprogrammées dans la mémoire, et que le dispositif de collecte peut être relevé de ses déchets soit pendant son parcours, soit celui-ci peut interrompre son parcours pour être vidé de ses déchets en allant à une position prédéfinie.We will now indicate an operating cycle by way of example only. Other operating cycles may be envisaged by those skilled in the art depending on the circumstances, in particular depending on the configuration of the operating zone or the nature of the waste to be collected. The collection device 1 functions in forward motion, with the first 46 and second 51 turbines operating in the same direction of rotation. According to an algorithm preprogrammed in the memory, the collection device moves over the surface of the zone to be scanned, then moves over the entire surface by parallel back and forth movements. In this step, the distance sensors indicate a material boundary, for example a jetty in a port. The collection device turns around and shifts thanks to the second 51 and third 69 turbines. Once the entire predefined surface has been scanned, the collection device performs a final pass over the periphery. This can also be controlled according to a clock, by example every 30 min or every hour. It is understood that the limits of the area to be scanned can be pre-programmed in the memory, and that the collection device can be relieved of its waste either during its course, or it can interrupt its course to be emptied of its waste. by going to a predefined position.

De façon avantageuse, lorsque les sondes de mesure 74 détectent la présence d'hydrocarbures, les moyens de commande 25 commandent le fonctionnement de la seule première turbine 46 pour le balayage, et n'activent la deuxième turbine 51 que pour manœuvrer le dispositif de collecte 1.Advantageously, when the measuring probes 74 detect the presence of hydrocarbons, the control means 25 control the operation of the first turbine 46 alone for sweeping, and activate the second turbine 51 only to operate the collection device 1.

Selon un mode de réalisation préféré, le parcours est préprogrammé dans la mémoire et le microprocesseur commande le fonctionnement des turbines en fonction.According to a preferred embodiment, the route is pre-programmed into the memory and the microprocessor controls the operation of the turbines accordingly.

De façon avantageuse, la mémoire pourra contenir différents algorithmes de fonctionnement que l'homme du métier saura choisir ou adapter en fonction de besoins.Advantageously, the memory may contain different operating algorithms that those skilled in the art will be able to choose or adapt according to needs.

Selon un autre mode de réalisation, le parcours, ou une modification du parcours en cours peut être téléchargé depuis une application mobile ou sur ordinateur associé, par l'intermédiaire des moyens de communication à distance.According to another embodiment, the route, or a modification of the route in progress, can be downloaded from a mobile application or on an associated computer, via remote communication means.

Il est bien entendu que les modes de réalisation qui viennent d'être décrits ont été donnés à titre indicatif et non limitatif et que des modes de réalisation peuvent y être apportés sans que l'on s'écarte pour autant du cadre de la présente invention, telle que définie par les revendications.It is understood that the embodiments which have just been described have been given by way of indication and are not limiting and that embodiments can be added thereto without thereby departing from the scope of the present invention. , as defined by the claims.
