Description

Dispositif de protection d'une coque de bateau à flot de l'agression des eaux maritimes Device for protecting a hull of a boat afloat from the aggression of maritime waters
La présente invention a pour objet un dispositif de protection adaptable à tout type de coques de bateaux, lorsque ces bateaux sont à flot, que ce soit à poste ou au mouillage.The present invention relates to a protective device adaptable to any type of boat hulls, when these boats are afloat, whether at post or at anchor.
Plus particulièrement, le dispositif crée une structure étanche autour de la totalité de la carène d'un navire, les eaux maritimes emprisonnées entre cette structure et ladite carène pouvant être expulsées vers les eaux maritimes du port par des moyens de vidage. Il y a également des moyens de remplissage permettant l'amenée d'eau douce dans 1 'espace compris entre structure et carène, afin de rincer et de nettoyer la coque du bateau du sel restant ou de souillures diverses.More particularly, the device creates a sealed structure around the entire hull of a ship, the sea water trapped between this structure and said hull being able to be expelled to the sea water of the port by emptying means. There are also filling means allowing fresh water to be brought into the space between structure and hull, in order to rinse and clean the hull of the boat of the remaining salt or various stains.
Traditionnellement il est d 'usage, dans le monde marin, de sortir un bateau hors de 1 ' eau, pour en nettoyer et repeindre la coque et les éléments qui sont immergés en continu ; hélice, arbre d 'hélice, gouvernail , stabilisateurs , soufflets, etc.Traditionally it is customary in the marine world to take a boat out of the water, to clean and repaint the hull and the elements which are continuously submerged; propeller, propeller shaft, rudder, stabilizers, bellows, etc.
Par ailleurs, il existe des procédés tels que nettoyages par brossages ou par jets sous pression en immersion pour enlever les algues et concrétions marines, lorsque les bateaux sont à flot.Furthermore, there are methods such as cleaning by brushing or by immersion pressure jets to remove the algae and marine concretions, when the boats are afloat.
Aucun procédé, à ce jour, ne permet d'éviter les opérations ci-dessus décrites. Il y a toujours eu, jusqu'à ce jour, repousse des algues et incrustations nouvelles de coquillages. L'état de la technique peut être défini par les documents suivants.No process, to date, makes it possible to avoid the operations described above. To this day, there has always been regrowth of algae and new shell encrustations. The state of the art can be defined by the following documents.
Le document US-R-3.685.477 propose un appareil de protection de la carène d'un bateau des salissures marines, lorsque le bateau est à flot dans de l'eau de mer. Cet appareil comporte une ossature métallique ayant une porte arrière. L'ossature est recouverte par une enveloppe constituée d'une feuille flexible et étanche qui définit un espace qui enveloppe le bateau. Une substance chimique imputrescible est ajoutée dans l'espace pour empêcher les salissures marines sur la carène du bateau. La porte et ses moyens d'attache à l'enveloppe sont abaissés pour permettre l'entrée ou la sortie du bateau afin d'être protégé. L'enveloppe flexible est attachée sur 1 'ossature par des moyens uniques permettant le déplacement de la feuille sans l'utilisation d'outils spéciaux, d' adhésif s ou d'éléments de fixation mécaniques.Document US-R-3,685,477 proposes a device for protecting the hull of a boat from marine soiling, when the boat is afloat in sea water. This device has a metal frame having a rear door. The frame is covered by an envelope made of a flexible and waterproof sheet which defines a space which envelops the boat. A rot-proof chemical is added to the space to prevent marine soiling on the boat's hull. The door and its means of attachment to the envelope are lowered to allow entry or exit of the boat in order to be protected. The flexible envelope is attached to the frame by unique means allowing movement of the sheet without the use of special tools, adhesives or mechanical fasteners.
Le document FR-Α-2.536.363 a trait à un procédé de protection de la coque d'un bateau contre les dépôts dus à la présence de substances marines animales ou végétales, lors de l'hivernage, dans lequel on entoure la coque jusqu'au-dessus de la ligne de flottaison à l'aide d'une housse étanche et opaque arrimée au pont du bateau. On évacue alors l'eau de mer située entre la housse et la coque puis on injecte une poche d'eau douce entre la housse et la coque. Cette dernière étant à l'abri de la lumière et du milieu marin, aucun dépôt indésirable ne vient se fixer sur elle et le Jateau conserve ses qualités de vitesse.The document FR-Α-2.536.363 relates to a process for protecting the hull of a boat against deposits due to the presence of animal or vegetable marine substances, during wintering, in which the hull is surrounded up to '' above the waterline using a waterproof and opaque cover stowed to the deck of the boat. The sea water located between the cover and the hull is then discharged and a pocket of fresh water is injected between the cover and the hull. The latter being protected from light and the marine environment, no unwanted deposit settles on it and the Jateau retains its speed qualities.
Le document EP-R-0.360.436 expose un procédé de protection d'une coque de bateau qui comprend le développement d'une enveloppe de protection autour de la coque et le traitement de l'eau emprisonnée pour inhiber l'action d'organismes marins. Lorsqu'on désire utiliser le bateau, l'enveloppe peut être rétractée vers une position non- encombrante dans laquelle elle occupe peu d'espace et où elle est exposée au minimum aux courants marins. La rétraction et le déploiement sont effectués en pliant un cadre ou un support sur lequel l'enveloppe est montée, et /ou de I 'enveloppe elle-même . Pendant l ' entreposage du bateau dans son enveloppe, l 'eau emprisonnée est vérifiée par une sonde et la quantité d ' agent de traitement pour neutraliser la vie marine est déterminée. Cette quantité précise est ajoutée dans l 'eau emprisonnée, et par conséquent cette dernière est rendue neutre par rapport à la coque et elle est pareillement inoffensive pour l 'environnement quand on la libère lors de la rétraction de 1 ' enveloppe .Document EP-R-0.360.436 describes a method of protecting a boat hull which includes the development of a protective envelope around the hull and the treatment of trapped water to inhibit the action of organisms sailors. When you want to use the boat, the envelope can be retracted to a space-saving position in which it occupies little space and where it is exposed at least to sea currents. The retraction and deployment are carried out by folding a frame or a support on which the envelope is mounted, and / or of the envelope itself. During the storage of the boat in its envelope, the trapped water is checked by a probe and the amount of treatment agent to neutralize marine life is determined. This precise quantity is added to the trapped water, and consequently the latter is made neutral with respect to the hull and it is likewise harmless for the environment when it is released during the shrinking of the envelope.
Enfin, le document US-R-5.152.242 a pour objet une enceinte de protection d ' une coque pour un bateau à flot et εtationnaire dans une quantité d ' eau comprise dans l ' enceinte. Une enveloppe flottante constitue une première cloison ayant une forme qui épouse approximativement le périmètre de la coque du bateau à la surface de l ' eau. Cette enveloppe forme un espace libre continu où est placé le bateau. Un cadre de protection , monté sur une tige flexible et continue, forme une seconde cloison située à la surface de l 'eau et épouse le périmètre de la coque du bateau alors que la tige flexible est au contact de la partie émergée de la première cloison. L'ensemble de ces documents propose une enveloppe souple qui circonscrit un espace d'eau où le bateau vient prendre place. L'objet de ces inventions est toujours de réduire les effets salissants des eaux maritimes, soit par un ajout de substances de traitement, soit par évacuation des eaux emprisonnées, soit par cloisonnement complet de ces eaux emprisonnées.Finally, document US-R-5,152,242 relates to an enclosure for protecting a hull for a boat afloat and stationary in a quantity of water included in the enclosure. A floating envelope constitutes a first partition having a shape which approximates the perimeter of the hull of the boat at the surface of the water. This envelope forms a continuous free space where the boat is placed. A protective frame, mounted on a flexible and continuous rod, forms a second partition located on the surface of the water and follows the perimeter of the boat hull while the flexible rod is in contact with the emerged part of the first partition. . All of these documents propose a flexible envelope which circumscribes a water space where the boat comes to take place. The object of these inventions is always to reduce the dirtying effects of maritime waters, either by adding treatment substances, or by evacuating trapped waters, or by complete partitioning of these trapped waters.
Ces techniques ne permettent néanmoins pas de mettre à l'air libre une partie de la carène ou des éléments mécaniques immergés, afin de les entretenir ou de les réparer, sans que le bateau ne soit sorti des eaux maritimes environnantes, alors que la présente invention propose un tel dispositif de protection.However, these techniques do not allow part of the hull or submerged mechanical elements to be exposed to the air in order to maintain or repair them, without the boat having left the surrounding maritime waters, whereas the present invention offers such a protection device.
A cet effet, ladite invention a pour objet un dispositif de protection d'une coque de bateau de l'agression des eaux maritimes, le bateau étant à flot à poste ou au mouillage, le dispositif est constitué d'une enveloppe de protection souple, destinée à couvrir la carène et équipée de moyens de manipulation et de fixation au bateau, et de moyens de vidage et de remplissage du milieu intérieur situé entre la coque et l'enveloppe, caractérisé par le fait que ladite enveloppe de protection coopère avec au moins un caisson rigide, que l'enveloppe et le(s) caisson(s) constituent un ensemble étanche pouvant être vidé des eaux, contenues dans le milieu intérieur situé entre la coque, d'une part, et l'enveloppe et le(s) caisson(s) d'autre part, par l'intermédiaire des moyens de vidage et de remplissage, et que chaque caisson rigide délimite un espace libre contre la coque, indéformable sous la pression de l'eau, lorsque l'ensemble étanche est vidé des eaux du milieu intérieur, ledit caisson rigide faisant alors office d'armature pour créer un puits de visite et une zone de travail et de protection pour la partie de la carène circonscrite et/ou pour les éléments mécaniques immergés.To this end, the subject of said invention is a device for protecting a hull of a boat from the aggression of maritime waters, the boat being afloat at anchor or at anchor, the device consists of a flexible protective envelope, intended to cover the hull and equipped with means for handling and fixing to the boat, and means for emptying and filling the interior environment located between the hull and the shell, characterized in that said protective shell cooperates with at least a rigid box, that the envelope and the (s) box (es) constitute a watertight assembly which can be emptied of the water, contained in the interior medium located between the hull, on the one hand, and the envelope and the box (es) on the other hand, by the intermediate emptying and filling means, and that each rigid box delimits a free space against the hull, non-deformable under the pressure of water, when the sealed assembly is emptied of the waters of the interior medium, said rigid box then acting of reinforcement to create a manhole and a work and protection zone for the part of the circumscribed hull and / or for the submerged mechanical elements.
Selon un premier mode de réalisation, chaque caisson est mobile par rapport à l'enveloppe de protection souple, et s'insère entre ladite enveloppe et la coque.According to a first embodiment, each box is movable relative to the flexible protective envelope, and is inserted between said envelope and the shell.
Selon un second mode de réalisation, chaque caisson est solidaire de l'enveloppe de protection.According to a second embodiment, each box is integral with the protective envelope.
Quel que soit le mode de réalisation, les moyens de vidage et de remplissage sont solidaires du caisson.Whatever the embodiment, the emptying and filling means are integral with the box.
Plus précisément, les moyens de vidage et de remplissage sont situés dans l'espace libre créé par le caisson. D'une part, l'enveloppe de protection souple comporte au moins un lest, afin de couler le dispositif de protection au fond du port lorsque le bateau est utilisé. D'autre part, ladite enveloppe est reliée à la chaine fille de l'emplacement, elle-même reliée à une chaîne mère ou à un corps-mort. Les moyens de vidage et de remplissage sont constitués par au moins :More specifically, the emptying and filling means are located in the free space created by the box. On the one hand, the flexible protective envelope comprises at least one ballast, in order to sink the protection device at the bottom of the port when the boat is used.

- une pompe à eau et un tube d'aspiration destinés au vidage, et- a water pump and a suction tube intended for emptying, and
- un tuyau d'amenée d'eau douce destiné au remplissage. Le tuyau d'amenée est situé sur la face intérieure de l'enveloppe de protection, qui est au contact de la coque lorsque le dispositif est mis en place, et est situé au niveau du bord de ladite enveloppe.- a fresh water supply hose for filling. The supply pipe is located on the inner face of the protective envelope, which is in contact with the shell when the device is put in place, and is located at the edge of said envelope.
De plus, ce tuyau comporte une multitude de trous sur toute sa longueur, qui font office de moyen de projection de l'eau douce.In addition, this pipe has a multitude of holes over its entire length, which act as a means of projecting fresh water.
L'enveloppe de protection comporte, au niveau de son pourtour, au moins une latte flexible bâbord et au moins une latte flexible tribord, faisant office de raidisseurs. L'enveloppe de protection possède une ou plusieurs surfaces en relief de structure ondulée créant des espaces libres entre la carène et l'enveloppe, ce qui facilite la circulation de l'eau ou de l'air pour le vidage et/ou le remplissage. Le caisson est constitué par :The protective envelope comprises, at its periphery, at least one flexible port slat and at least one flexible starboard slat, acting as stiffeners. The protective casing has one or more raised surfaces of undulating structure creating free spaces between the hull and the casing, which facilitates the circulation of water or air for emptying and / or filling. The box is made up of:
- des éléments d'appui latéraux sur la coque,- lateral support elements on the hull,
- des éléments d'appui inférieurs sous la coque, et- lower support elements under the hull, and
- un espace libre destiné à recevoir et à protéger des éléments mécaniques immergés du bateau et/ou à accueillir au moins une personne, affectée à l'entretien et à la maintenance de ces éléments mécaniques, cet espace comportant un plancher faisant office de plan de travail.- a free space intended to receive and protect submerged mechanical elements of the boat and / or to accommodate at least one person, assigned to the upkeep and maintenance of these mechanical elements, this space comprising a floor serving as a plan of job.
Selon une première variante de réalisation, les éléments d'appui sont constitués par des ailes planes ou raidisseurs dont les formes épousent la forme arrière de la coque.According to a first embodiment, the support elements consist of flat wings or stiffeners whose shapes match the rear shape of the hull.
Selon une seconde variante de réalisation, les éléments d'appui sont constitués par des bras recouverts, en tout ou partie, par des éléments de protection élastique dont la forme s'adapte à celle de la coque. Le caisson comporte une structure modulaire.According to a second alternative embodiment, the support elements consist of arms covered, in whole or in part, by elastic protection elements whose shape adapts to that of the shell. The box has a modular structure.
Le dispositif selon l'invention permet de remédier d'une façon définitive à ce problème millénaire et à éliminer, au niveau de la plaisance, notamment la pollution engendrée par les peintures de protection sous-marines très nocives. Le dispositif selon l'invention permet, par exemple, à un bateau amarré à quai, de ne jamais être en contact avec l'eau de mer, alors qu'il flotte en eau de mer et d'être au sec alors qu'il flotte après avoir été rincé à l'eau douce.The device according to the invention makes it possible to definitively remedy this thousand-year-old problem and to eliminate, in terms of boating, in particular the pollution caused by very harmful underwater protective paints. The device according to the invention allows, for example, a boat moored at the quay, never to be in contact with sea water while it is floating in sea water and to be dry while it floats after being rinsed with fresh water.
Selon le mode particulier de réalisation : - le dispositif est muni d'un châssis-cage ou caisson rigide adapté à la forme des éléments de propulsion, de guidage, ou de stabilisation immergés ; à la fois hors de l'eau et dans l'eau, ce châssis-cage sert à protéger l'hélice, l'arbre, le gouvernail, etc. , - ce châssis-cage est habillé d'une bâche étanche ou enveloppe de protection qui se continue sous la coque du navire pour l'envelopper en remontant sur les flancs,According to the particular embodiment: - the device is provided with a chassis-cage or rigid box adapted to the shape of the propulsion, guide or stabilizing elements immersed; both out of the water and in the water, this cage frame is used to protect the propeller, the shaft, the rudder, etc. , - this chassis-cage is covered with a waterproof tarpaulin or protective envelope which continues under the ship's hull to wrap it up on the sides,
- l'ensemble bâche/châssis-cage est attaché aux taquets du navire,- the tarpaulin / chassis-cage assembly is attached to the cleats of the ship,
- lorsque cette dernière opération est terminée, une pompe située dans la partie étanche du châssis-cage, vide l'eau de mer pour mettre la coque au sec alors que le navire est à flot, - l'hélice ou l'ensemble moteur hors-bord se trouvant à sec, il est possible alors d'en assurer le nettoyage ou l'entretien, le bateau étant toujours à flot,- when this last operation is finished, a pump located in the watertight part of the chassis-cage, empties the sea water to dry the hull while the ship is afloat, - the propeller or the engine assembly out -board being dry, it is then possible to ensure cleaning or maintenance, the boat is always afloat,
- il est possible de rincer, également, la coque et le moteur à l'eau douce en remplissant, à l'eau douce, le volume situé entre la coque et la bâche ; en vidant à nouveau avec la pompe, la coque est à nouveau à sec,- it is possible to rinse, also, the hull and the engine with fresh water by filling, with fresh water, the volume located between the hull and the cover; by emptying again with the pump, the hull is again dry,
- lorsque le bateau doit naviguer, il suffit de détacher la bâche des taquets et grâce au lest ou à son poids, ladite bâche s'enfonce dans l'eau en étant reliée à un corps-mort flottant ou à la chaîne fille ; le bateau est alors libéré, et- when the boat has to sail, it is enough to detach the tarpaulin from the cleats and thanks to the ballast or its weight, said tarpaulin sinks into the water while being connected to a floating mooring or to the daughter chain; the boat is then released, and
- au retour du bateau à quai, il suffit de tirer les pendilles du corps-mort pour replacer la bâche, vider l'eau et isoler ainsi la coque et les éléments immergés de l'eau de mer.- when returning from the boat to the quay, it is enough to pull the pendulum from the mooring to replace the cover, empty the water and thus isolate the hull and the submerged elements from the sea water.
Le châssis peut être fabriqué à partir d'alliages souples ou rigides, de composants pétrochimiques type PVC, polyester ou d'acier.The chassis can be manufactured from flexible or rigid alloys, petrochemical components such as PVC, polyester or steel.
Le dispositif de protection, destiné à isoler de l'eau de mer ou à laisser au sec les coques de navires alors qu'ils sont à flot, est caractérisé en ce qu'il est constitué d'un châssis-cage ou caisson qui protège de l'agression marine les éléments mécaniques immergés en étant lui-même prolongé par l'habillage étanche d'une bâche ou enveloppe de protection qui se déplie et enveloppe la coque en remontant sur les flancs du navire.The protection device, intended to isolate seawater or to keep ship hulls dry while they are afloat, is characterized in that it consists of a cage-frame or box which protects from marine aggression, the submerged mechanical elements itself being extended by the waterproof covering of a tarpaulin or protective envelope which unfolds and envelops the hull while going up on the sides of the ship.
Le châssis-cage peut être rigide ou souple et coulissant sur lui-même selon la forme de la coque, ou de la protection à effectuer.The cage frame can be rigid or flexible and sliding on itself depending on the shape of the shell, or the protection to be provided.
La bâche peut être munie d'un lest dans sa partie longitudinale.The tarpaulin can be provided with a ballast in its longitudinal part.
Le châssis-cage, adapté à la forme des éléments de propulsion, de guidage ou de stabilisation, immergés, est muni d'une ou plusieurs pompes à eau et d'une vanne de remplissage d'eau de mer.The cage frame, adapted to the shape of the submerged propulsion, guide or stabilization elements, is fitted with one or more water pumps and a seawater filling valve.
L'ensemble châssis-cage et bâche est relié aux pendilles du corps mort ou de la chaîne fille. Le châssis renforçant la cage peut être fabriqué à partir d'alliages souples ou rigides, de composants pétrochimiques type PVC, polyester ou d'acier.The chassis-cage and tarpaulin assembly is connected to the pendulums of the dead body or the daughter chain. The frame reinforcing the cage can be made from flexible or rigid alloys, petrochemical components such as PVC, polyester or steel.
Selon un mode particulier de réalisation, la bâche relie deux châssis-cage permettant le déroulement de ladite bâche, d'un châssis sur l'autre.According to a particular embodiment, the cover connects two chassis-cage allowing the unfolding of said cover, from one chassis to the other.
Dans une autre réalisation, les châssis-cages sont munis de boudins étanches devant faire pression sur la coque pour assurer une jointure étanche à tout liquide. Les châssis-cages et les boudins étanches de pression de coque sont reliés de manière étanche à la bâche pour en faire un ensemble totalement étanche, une coque souple.In another embodiment, the frame-cages are provided with watertight tubes which have to press on the hull to ensure a tight seal against any liquid. The chassis-cages and the tight hull pressure tubes are tightly connected to the tarpaulin to make a completely waterproof assembly, a flexible hull.

Enfin la figure 9 représente une vue de face d'un caisson comportant deux espaces libres. La présente invention concerne un dispositif de protectionFinally, FIG. 9 represents a front view of a box comprising two free spaces. The present invention relates to a protection device
1 permettant d'isoler, de l'élément liquide tel que les eaux maritimes 4, à la demande et pour des périodes indéterminées, toutes les pièces immergées 12 d'un corps flottant ou bateau 3 et ce grâce à une protection mécanique.1 making it possible to isolate, from the liquid element such as maritime waters 4, on request and for indefinite periods, all the submerged parts 12 of a floating body or boat 3, and this thanks to mechanical protection.
Ainsi, il ne sera plus jamais indispensable de sortir un bateau 3 hors de l'eau 4 et il sera possible d'isoler, sur un navire 3, tout ou partie de sa coque 2 immergée ou non.Thus, it will never again be essential to take a boat 3 out of the water 4 and it will be possible to isolate, on a ship 3, all or part of its hull 2 whether submerged or not.
La présente invention concerne un dispositif de protection 1 destiné à venir couvrir la totalité de la carène 6 d'un bateau 3 et la quasi-totalité de la coque 2 de ce bateau 3.The present invention relates to a protection device 1 intended to cover the entire hull 6 of a boat 3 and almost all of the hull 2 of this boat 3.
Cette protection est essentiellement réalisée pour lutter contre les salissures provenant des eaux maritimes 4 qui constituent le milieu environnant dudit bateau 3. Ce dispositif de protection 1 est essentiellement constitué, comme on le voit sur la figure 2, par un caisson 10 et une enveloppe de protection 5. Ce mode de réalisation avec des variantes est représenté sur l'ensemble des figures 1 à 9 ci- jointes. Néanmoins, selon un mode de réalisation particulier qui est revendiqué, l'enveloppe de protection peut circonscrire un volume plus important et englober également le caisson. Dans ce mode de réalisation non représenté, le caisson sera donc mobile par rapport à l'enveloppe, ce qui n'est pas le cas sur les figures. Ce mode de réalisation, non représenté, permet par exemple, par vidage et repositionnement successif du caisson, de traiter l'ensemble de la carène d'un bateau.This protection is essentially carried out to combat dirt from maritime waters 4 which constitute the surrounding environment of said boat 3. This protection device 1 is essentially constituted, as can be seen in FIG. 2, by a box 10 and an envelope of protection 5. This embodiment with variants is shown in all of Figures 1 to 9 attached. However, according to a particular embodiment which is claimed, the protective envelope can circumscribe a larger volume and also include the box. In this embodiment not shown, the box will therefore be movable relative to the envelope, which is not the case in the figures. This embodiment, not shown, allows for example, by emptying and successive repositioning of the box, to treat the entire hull of a boat.
En exagérant à l'extrême, il est possible grâce à ce mode de réalisation où le caisson serait adaptable à toutes formes de la coque, de repeindre entièrement une coque d'un bateau à flot.By exaggerating to the extreme, it is possible thanks to this embodiment where the box would be adaptable to all forms of the hull, to completely repaint a hull of a boat afloat.
Pour cela, pour chaque partie circonscrite par le caisson, il sera nécessaire de positionner le caisson, évacuer les eaux, sécher, poncer, peindre, laisser sécher et enfin, réintroduire de l'eau avant de déplacer le caisson vers un autre point de la carène que l'on désire traiter de la même façon. En renouvelant cette action plusieurs fois, il sera possible de traiter l'ensemble de la carène.For this, for each part circumscribed by the box, it will be necessary to position the box, evacuate the water, dry, sand, paint, let dry and finally, re-introduce water before moving the box to another point of the hull that we want to treat in the same way. By repeating this action several times, it will be possible to treat the entire hull.
On peut remplacer ce travail de peinture par un traitement contre les souillures diverses provenant des eaux 4. Selon les figures 1 à 9, le mode de réalisation du dispositif de protection 1 est constitué d'un caisson 10 qui est solidarisé à l'enveloppe de protection 5 par l'intermédiaire de moyens de fixation, non référencés, appartenant au domaine public. Le caisson a une forme particulière qui permet d'isoler, comme on le voit sur les figures 3 et 4, des éléments mécaniques immergés 12 tels qu'un moteur, un gouvernail ou autre.This paint job can be replaced by a treatment against various stains from water 4. According to Figures 1 to 9, the embodiment of the protective device 1 consists of a box 10 which is secured to the protective casing 5 by means of attachment, not referenced, belonging to the public domain. The box has a particular shape which makes it possible to isolate, as can be seen in FIGS. 3 and 4, submerged mechanical elements 12 such as a motor, a rudder or the like.
Etant donné que ces éléments 12 sont assez volumineux, le caisson 10 comporte un espace libre 11 servant de puits de visite pour qu'une personne habilitée puisse travailler sur lesdits éléments 12. Pour arriver à ce résultat, il est nécessaire de mettre en place, comme on le voit sur la figure 3, le dispositif de protection 1.Since these elements 12 are quite bulky, the box 10 has a free space 11 serving as an inspection well so that an authorized person can work on said elements 12. To achieve this result, it is necessary to set up, as seen in Figure 3, the protection device 1.
Selon cette figure, l'enveloppe 5 est présente aux niveaux latéraux du bateau 3 ainsi qu'au niveau de sa proue, alors que le caisson 10 est présent au niveau de la poupe dudit bateau 3.According to this figure, the envelope 5 is present at the lateral levels of the boat 3 as well as at the level of its bow, while the box 10 is present at the stern of said boat 3.
L'ensemble des eaux maritimes 4 ne sont pas en contact avec le bateau 3 et les eaux maritimes restant emprisonnées entre le caisson 10 et l'enveloppe 5, d'une part, et le bateau 3, d'autre part, sont évacuées à l'aide de moyen de vidage et de remplissageAll the sea waters 4 are not in contact with the boat 3 and the sea waters remaining trapped between the box 10 and the casing 5, on the one hand, and the boat 3, on the other hand, are discharged to by means of emptying and filling
9.9.
Ces moyens 9 sont essentiellement constitués par une pompe associée avec un élément d'évacuation tel qu'une tuyauterie permettant l'amenée ou le refoulement de l'eau située dans cet espace.These means 9 are essentially constituted by a pump associated with a discharge element such as a pipe allowing the supply or the discharge of the water located in this space.
Afin de pouvoir vider la totalité de l'eau, même celle qui se trouve située au niveau de la proue, on peut adjoindre à la pompe une tuyauterie d'amenée des eaux qui se trouvent coincées entre enveloppe 5 et coque 2. Lorsque le vidage a été réalisé, et comme on le voit bien sur la figure 4, l'espace compris entre le bateau 3 et le dispositif 1 est au sec.In order to be able to empty all the water, even that which is located at the level of the bow, it is possible to add to the pump a water supply pipe which is trapped between casing 5 and hull 2. When the emptying has been carried out, and as can be seen in FIG. 4, the space between the boat 3 and the device 1 is dry.
L'espace libre 11 permettra donc à une personne de travailler sur les éléments mécaniques 12 qui sont normalement immergés tout en étant au sec alors que le bateau 3 est à flot.The free space 11 will therefore allow a person to work on the mechanical elements 12 which are normally submerged while being dry while the boat 3 is afloat.
Afin de faciliter le vidage ou le remplissage des eaux situées dans l'espace compris entre le dispositif 1 et la coque 2, l'enveloppe de protection 5 peut comporter une structure en relief ondulé 20, comme cela est représenté sur la figure 6, ce qui crée des espaces incompressibles par les eaux maritimes 4 lorsque les eaux circonscrites ont été évacuées.In order to facilitate the emptying or filling of the water located in the space between the device 1 and the shell 2, the protective envelope 5 may include a structure in wavy relief 20, as shown in FIG. 6, which creates spaces that cannot be compressed by maritime waters 4 when the circumscribed waters have been evacuated.
Selon un mode de réalisation représenté sur la figure 6, et afin de faciliter le nettoyage de la carène 6, l'enveloppe de protection 5 est associée à un tuyau 16 permettant l'amenée d'eau douce provenant d'un robinet 32, situé sur le quai, cette eau douce étant destinée à remplacer des eaux maritimes qui étaient emprisonnées, entre la carène 6, d'une part, et l'enveloppe 5 et le caisson 10 d'autre part, ceci dans un but de rinçage complet, de sorte que l'élimination des eaux salées et des salissures dues aux eaux maritimes 4 soit la plus complète possible. L'eau douce parcourant le tuyau 16 peut être projetée dans l'espace à rincer par l'intermédiaire de moyens de projection 17 constitués par des trous 17. Lorsque le dispositif de protection 1 n'est pas utilisé, c'est-à-dire que le bateau ne nécessite pas de protection ou est en service, il 1 peut être, comme cela est représenté sur la figure 5, coulé au fond du port 14, le dispositif 1 reste en position au fond dudit port 14, du fait de la présence des moyens de manipulation 7 qui solidarisent le dispositif 1 d'une part à un anneau d'amarrage 29, situé sur le quai, et d'autre part à un corps-mort 15, situé au fond du port 14, par l'intermédiaire d'une chaîne fille 13, elle-même associée à une bouée 28 ou à une pendille reliée à la chaîne mère. Contrairement à ce qui précède, lorsque le dispositif de protection 1 est mis en place sur le bateau 3, comme c'est le cas sur la figure 3, l'enveloppe de protection 5 est maintenue en position contre la coque 2 du bateau 3 par l'intermédiaire de moyens de fixation 8. Ces moyens 8 sont constitués par des tendeurs, des cordes, etc. ou tous moyens du domaine public.According to an embodiment shown in FIG. 6, and in order to facilitate cleaning of the hull 6, the protective envelope 5 is associated with a pipe 16 allowing the supply of fresh water coming from a tap 32, located on the quay, this fresh water being intended to replace maritime waters which were trapped, between the hull 6, on the one hand, and the casing 5 and the box 10 on the other hand, this for the purpose of complete rinsing, so that the elimination of salt water and soiling due to maritime waters 4 is as complete as possible. The fresh water passing through the pipe 16 can be projected into the space to be rinsed by means of projection means 17 constituted by holes 17. When the protection device 1 is not used, that is to say say that the boat does not require protection or is in service, it 1 may be, as shown in Figure 5, sunk at the bottom of port 14, the device 1 remains in position at the bottom of said port 14, due to the presence of the handling means 7 which secure the device 1 on the one hand to a mooring ring 29, located on the quay, and on the other hand to a mooring 15, located at the bottom of the port 14, by the 'intermediary of a daughter chain 13, itself associated with a buoy 28 or a pendulum connected to the mother chain. Contrary to the above, when the protection device 1 is put in place on the boat 3, as is the case in FIG. 3, the protective envelope 5 is held in position against the hull 2 of the boat 3 by by means of fixing means 8. These means 8 are constituted by tensioners, ropes, etc. or any means in the public domain.
En règle générale, pour faciliter le stockage du dispositif 1 au fond du port 14, l'enveloppe 5 est lestée par l'intermédiaire d'une masse située longitudinale ent et allant de la proue à la poupe sous le bateau 3. Néanmoins et tout simplement, le poids du dispositif de protection 1 exerce une traction à l'opposé du corps-mort 15 ou de la force exercée par la pendille.In general, to facilitate the storage of the device 1 at the bottom of the port 14, the casing 5 is ballasted by means of a mass located longitudinally and going from the bow to the stern under the boat 3. Nevertheless and all simply, the weight of the protective device 1 exerts a traction opposite to the mooring 15 or the force exerted by the pendulum.
Dans un but esthétique, comme on le voit sur la figure 6, la partie supérieure de l'enveloppe 5 comporte des lattes flexibles * For aesthetic purposes, as can be seen in FIG. 6, the upper part of the casing 5 has flexible slats *
1111
18 et 19 qui viennent, par déformation, épouser la surface périphérique de la coque 2 du bateau 3.18 and 19 which come, by deformation, to marry the peripheral surface of the hull 2 of the boat 3.
Selon un autre mode de réalisation du caisson, celui-ci 30 est de constitution modulaire. Il comporte un certain nombre d'éléments.According to another embodiment of the box, the box 30 is of modular construction. It has a number of elements.
Outre les cloisons qui forment l'espace libre 11, le caissonIn addition to the partitions which form the free space 11, the box
30 comporte un capotage 31 pouvant recevoir les moyens de vidage et de remplissage 9 ainsi que des bras d'appui inférieurs 24 pouvant comporter des éléments de protection 27 destinés à épouser la forme de la coque 2.30 includes a cowling 31 which can receive the emptying and filling means 9 as well as lower support arms 24 which can include protective elements 27 intended to follow the shape of the shell 2.
Il comporte également, comme on le voit sur la figure 8, des bras d'appui latéraux 23, qui constituent des raidisseurs latéraux, destinés à rigidifier les points de fixation de l'enveloppe 5 vis-à-vis de toute la largeur de la poupe dudit bateau 3.It also comprises, as can be seen in FIG. 8, lateral support arms 23, which constitute lateral stiffeners, intended to stiffen the attachment points of the casing 5 with respect to the entire width of the stern of said boat 3.
Selon les figures 1 et 2, ces bras sont remplacés par des ailes d'appui latérales 21 et des ailes d'appui inférieures 22, celles-ci pouvant également recevoir des éléments de protection. Ces éléments de protection 27 sont par exemple constitués de bloc de mousse d'une densité adaptée aux pressions subies. Ils peuvent être constitués de blocs de néoprène qui sont adaptés aux appuis selon la forme des coques 2 immergées et sont fixés sur les ailes 21 et/ou 22.According to Figures 1 and 2, these arms are replaced by lateral support wings 21 and lower support wings 22, these can also receive protective elements. These protective elements 27 are for example made of foam block of a density adapted to the pressures undergone. They can be made of neoprene blocks which are adapted to the supports according to the shape of the submerged shells 2 and are fixed on the wings 21 and / or 22.
Quel que soit le mode de réalisation du caisson 10 ou 30, celui-ci comporte un plancher 25 ou 26 qui sert de plan de travail pour la personne qui va venir travailler dans l'espace libre 11 vidé des eaux maritimes 4.Whatever the embodiment of the box 10 or 30, it includes a floor 25 or 26 which serves as a work plan for the person who will come to work in the free space 11 emptied of maritime waters 4.
Selon la figure 9 enfin, un mode de réalisation à deux espaces libres est présenté. Ce mode de réalisation est particulièrement adapté au bateau comportant deux moteurs in-bord.According to FIG. 9, finally, an embodiment with two free spaces is presented. This embodiment is particularly suitable for boats with two inboard engines.
Selon un mode particulier de réalisation, le caisson peut être constitué par une armature recouvert par une toile souple et renforcée.According to a particular embodiment, the box can be constituted by a frame covered by a flexible and reinforced canvas.
De plus, le caisson peut être désolidarisé de l'enveloppe de protection, s'il est équipé sur ses arêtes, constituant son pourtour immergé, d'un boudin lui assurant une étanchéité totale.In addition, the box can be detached from the protective envelope, if it is equipped on its edges, constituting its immersed periphery, with a flange ensuring a total seal.
Enfin, l'enveloppe de protection peut relier plusieurs caissons.Finally, the protective envelope can connect several boxes.
Les éléments d'appui latéraux 21 et 23, placés sur le côté 12 des coques 2, et les éléments d'appui inférieurs 22 et 24, placés sous lesdites coques 2, des caissons 10 et 30 constituent des bras de blocage en position desdits caissons 10 et 30 par rapport aux coques 2 de bateaux 3. Les bras latéraux 21 et 23 ont une position sensiblement verticale, alors que les bras inférieurs 22 et 24 ont une position sensiblement horizontale, de sorte que la concavité créée entre les bras 21 et 23, d'une part, et 22 et 24, d'autre part, facilite la fixation des caissons 10 et 30 sur les coques 2. L'ensemble des parties de chaque caisson 10 ou 30 qui coopère directement avec une coque 2 peut être équipé d 'un boudin étanche qui permet, une fois plaqué contre la coque 2 et que le caisson 10 ou 30 est vidé, de créer un espace libre et sec contre ladite coque 2. Dans le cas où le bateau 3 est un voilier, comportant une quille, une ouverture est pratiquée dans l'enveloppe de protection au niveau de la quille. Une seconde enveloppe de protection, non représentée sur les figures, a une forme de chaussette qui peut contenir ladite quille. Les deux enveloppes sont reliées entre elles, au niveau de l'ouverture de la première enveloppe, par tous moyens de fixation du domaine public, par exemple un cadre à quille. Bien entendu, un tube d'aspiration, relié à la pompe, permet l'évacuation des eaux présentes entre la quille et l'enveloppe en forme de chaussette. Néanmoins, les deux enveloppes pourraient ne constituer qu'une seule et unique enveloppe dont la forme concave serait adaptée à la forme convexe de la coque du voilier. The lateral support elements 21 and 23, placed on the side 12 of the hulls 2, and the lower support elements 22 and 24, placed under said hulls 2, boxes 10 and 30 constitute locking arms in position of said boxes 10 and 30 relative to the hulls 2 of boats 3. The arms side 21 and 23 have a substantially vertical position, while the lower arms 22 and 24 have a substantially horizontal position, so that the concavity created between the arms 21 and 23, on the one hand, and 22 and 24, on the other part, facilitates the fixing of the boxes 10 and 30 on the shells 2. All of the parts of each box 10 or 30 which cooperates directly with a shell 2 can be equipped with a sealed flange which allows, once pressed against the shell 2 and that the box 10 or 30 is emptied, to create a free and dry space against said hull 2. In the case where the boat 3 is a sailboat, comprising a keel, an opening is made in the protective envelope at the level from the keel. A second protective envelope, not shown in the figures, has the shape of a sock which can contain said keel. The two envelopes are connected together, at the opening of the first envelope, by any means of fixing the public domain, for example a keel frame. Of course, a suction tube, connected to the pump, allows the evacuation of the water present between the keel and the sock-shaped envelope. However, the two envelopes could constitute only one single envelope whose concave shape would be adapted to the convex shape of the hull of the sailboat.
