Description
Dock de relevaqe de structure flottante, adapté particulièrement au carénage et au lavage rapide de bateau de petite taille Floating structure lift dock, particularly suitable for fairing and fast washing of small boats
La présente invention a pour objet des docks de relevage de structures flottantes adaptés particulièrement au carénage et au lavage rapide de bateaux de petite taille.The present invention relates to lifting docks floating structures particularly suitable for fairing and fast washing small boats.
Le secteur technique de l'invention est le domaine des équipements à usage maritime, fluviaux ou lacustres aptes à sortir de l'eau différents types de structures flottantes, tels que les bateaux de plaisance mais aussi des unités plus importantes, pour en permettre la réparation, le carénage, l'inspection etcThe technical sector of the invention is the field of equipment for maritime, river or lake use able to get out of the water different types of floating structures, such as pleasure boats but also larger units, to allow repair , fairing, inspection etc
On connaît pour cela différents dispositifs que l'on peut classer en trois familles telles que :We know for this different devices that can be classified into three families such as:
- les remorques sur pneus ou les chariots sur rail que l'on glisse, par des rampes inclinées en partie immergées jusqu'à une profondeur suffisante, sous la coque des bateaux à flot que l'on remonte ainsi à l'aide de treuil ou de tracteur, nécessitant cependant une infrastructure terrestre de génie civil importante même pour les unités de petite taille.- wheeled trailers or rail carriages which are slipped by ramps inclined at least partially submerged to a sufficient depth, under the hull of the boats afloat that is thus raised using a winch or of tractor, however requiring a major civil engineering earth infrastructure even for small units.
- Des docks flottants comprenant un plateau caisson immergeable par remplissage de ballasts latéraux, ceci formant avec ce plateau caisson une structure en forme de U au milieu de laquelle est amenée puis supportée la structure flottante que l'on veut sortir de l'eau en émergeant le plateau caisson par vidange de ballasts latéraux qui assurent également la stabilité de l'ensemble : ce type d'équipements sont très lourds et réservés aux grosses unités tels que les gros bateaux de pêche, les cargos, les car-ferries etc....
- Dans le domaine des petites unités telles que les bateaux de petite taille de l'ordre de 5 à 14 mètres de longueur il est courant d'utiliser des grues ou portiques de manutention placés sur les quais en bordure des bassins portuaires et soulevant les bateaux à l'aide de sangles glissées sous la coque, et les déposant à quai sur des bers .- Floating docks comprising a submergible caisson tray filling lateral ballasts, this forming with this caisson plate a U-shaped structure in the middle of which is brought and supported the floating structure that we want to get out of the water emerging the box tray by draining side ballasts which also ensure the stability of all: this type of equipment is very heavy and reserved for large units such as large fishing boats, cargo ships, car ferries etc ... . - In the field of small units such as small boats of the order of 5 to 14 meters in length it is common to use cranes or gantry cranes placed on the docks bordering the harbor basins and lifting the boats using straps slipped under the hull, and depositing them on berths.
Cependant une telle mise sur ber est toujours une opération pénible, car d'une part elle est tributaire des opérateurs des moyens de levage qui sont souvent tous surchargés, d'autre part elle bloque le bateau plusieurs jours et nécessite une organisation plusieurs semaines, si ce n'est des mois, à l'avance : elle est également assez coûteuse ; de plus malgré des améliorations constantes apportées aux aires de carénage existantes, de nombreux disfonctionnements continuent de porter atteinte à l'environnement par le ruissellement et les rejets directs, dans le bassin du port, des effluents de carénage de coque, qui transportent des charges polluantes mal maîtrisées et souvent toxiques.However such a bet on ber is always a painful operation, because on the one hand it is dependent on the operators lifting means that are often all overloaded, on the other hand it blocks the boat several days and requires an organization several weeks, if it is months in advance: it is also quite expensive; moreover, despite constant improvements to the existing refit areas, many malfunctions continue to affect the environment through runoff and direct discharges of hull fairing effluents into the harbor basin, which carry polluting loads. poorly controlled and often toxic.
Le problème posé est ainsi de pouvoir disposer d'un dispositif de relevage de structure flottante, adapté particulièrement au carénage et lavage rapide de bateaux de petite taille, apte à répondre aux inconvénients des systèmes actuels, en assurant en particulier un relevage hors d'eau à tout moment, pouvant être effectué par l'utilisateur lui-même de la structure flottante, tel que le propriétaire ou le skipper d'un bateau de plaisance, sans intervention ou aide extérieure, et sans nécessiter d'infrastructure de génie civil importante, afin de permettre ensuite et essentiellement le carénage rapide et le lavage de la structure flottante, et sans, de plus,
polluer le milieu naturel par rejet des effluents dans celui-ci.The problem posed is thus to have a floating structure lifting device, particularly suitable for fairing and fast washing of small boats, able to meet the disadvantages of the current systems, ensuring in particular a lifting out of water at any time, which may be carried out by the user himself of the floating structure, such as the owner or skipper of a pleasure craft, without intervention or outside assistance, and without the need for major civil engineering infrastructure, to allow then and essentially the fast fairing and washing of the floating structure, and without, moreover, pollute the natural environment by discharging effluents into it.
Une solution au problème posé est un dock maritime, fluvial ou lacustre, puisque son usage peut s'adapter au port maritime mais également aux fleuves, canaux et lacs, pour le relevage de structure flottante, et comprenant un plateau caisson immergeable apte à supporter ladite structure flottante et des moyens supports et de translation verticale aptes à émerger et immerger ledit plateau caisson.A solution to the problem posed is a maritime, fluvial or lacustrine dock, since its use can adapt to the seaport but also to rivers, canals and lakes, for the lifting of floating structure, and including a submergible caisson tray able to support said floating structure and support means and vertical translation able to emerge and immerse said box tray.
Selon l'invention ledit dock comporte un système de guidage relié à au moins un élément de fondation fixe et coopérant avec le plateau caisson de telle façon que celui-ci soit maintenu suivant des positions prédéterminées pendant sa translation verticale entre une position immergée permettant la prise en charge de la structure flottante et une position émergée permettant d'accéder à sec à l'ensemble de la carène de la structure flottante .According to the invention said dock comprises a guiding system connected to at least one fixed foundation element and cooperating with the caisson plate so that it is held in predetermined positions during its vertical translation between a submerged position allowing the capture in charge of the floating structure and an emergent position allowing dry access to the entire hull of the floating structure.
Il peut être utilisé différents moyens supports de translation verticale tels que décrits ci-après, combinés avec différents systèmes de guidage lors de cette translation, ceux-ci étant essentiels pour la stabilité d'ensemble du plateau caisson supportant la structure flottante.It can be used different vertical translation support means as described below, combined with different guidance systems during this translation, these being essential for the overall stability of the box tray supporting the floating structure.
Selon un mode préférentiel de réalisation le dock suivant l'invention comporte au moins une passerelle flottante à la latitude contrôlée, reliée au moins à une de son extrémité à un accès piétons, maintenue au-dessus du plateau caisson en position immergée et apte alors au guidage de la structure flottante, et à permettre l'accès à pied à celle-ci.
Par ailleurs et préférentiellement le dock suivant l'invention comporte également un bloc technique en une ou plusieurs parties, apte à permettre le lavage et le carénage de la structure flottante une fois émergée, ledit bloc technique comprenant des dispositifs de récupération de traitement des effluents s' écoulant sur le plateau caisson, ainsi que des moyens de commande de manœuvre du dock.According to a preferred embodiment, the dock according to the invention comprises at least one floating gateway at the controlled latitude, connected at least to one of its end to a pedestrian access, maintained above the caisson plate in submerged position and then suitable for guiding the floating structure, and to allow foot access to it. Furthermore and preferably the dock according to the invention also comprises a technical block in one or more parts, able to allow washing and fairing of the floating structure once emerged, said technical unit comprising effluent treatment recovery devices. flowing on the caisson plate, as well as control means for maneuvering the dock.
Le résultat est un nouveau équipement à usage maritime, fluvial ou lacustre apte à sortir de l'eau des structures flottantes de petite taille pour en permettre l'inspection, la réparation ou le lavage et/ou le carénage, répondant au problème posé et satisfaisant aux inconvénients des dispositifs actuels. En effet la combinaison d'un plateau caisson, de moyens supports de translation verticale et d'un système de guidage, permet de réaliser un dock de petite dimension et suffisamment stable, qui est facilement installable dans un site portuaire ou autre et sans nécessiter d' infrastructure importante de génie civil : le dock est disposé directement dans le bassin d'eau et proche d'un quai, sur lequel peut être installé le bloc technique, évitant le rejet des effluents dans le bassin. Un tel dock équipé au moins d'une passerelle flottante de guidage à l'accostage et d'accès peut être opéré par une seule personne indépendamment de toute intervention ou aide extérieure : ainsi au même titre que les automobilistes qui utilisent actuellement des stations de lavage autonomes pour laver leur voiture, le plaisancier pourra, seul et sans aide, accoster sur le dock, débarquer de celui-ci et relever son bateau puis accéder à sa carène en quelques minutes et y travailler pendant le temps qui lui est nécessaire, et cela sans rendez-vous, si le dock est disponible, et
avec une dépense très largement inférieure à une mise en cale traditionnelle.The result is a new equipment for maritime, river or lake use able to get out of the water small floating structures to allow inspection, repair or washing and / or fairing, responding to the problem and satisfactory the disadvantages of current devices. Indeed, the combination of a box tray, vertical translation support means and a guide system, allows for a dock of small size and sufficiently stable, which is easily installed in a port site or other and without requiring Important infrastructure of civil engineering: the dock is placed directly in the water basin and close to a dock, on which can be installed the technical block, avoiding the discharge of effluents into the basin. Such a dock equipped with at least one floating bridge for docking and access guidance can be operated by a single person independently of any intervention or outside help: as well as motorists who currently use wash stations autonomous to wash their car, the boater can, alone and without help, dock on the dock, disembark from it and raise his boat then access to its hull in a few minutes and work there for the time it is necessary, and this without an appointment, if the dock is available, and with an expense much lower than a traditional docking.
La conception, la sécurité d'accès et les contrôles (obligatoires pour toutes manutentions d'engins de levage) que permettent la présente invention, offrent ainsi un dispositif de carénage de lavage rapide en « self service » qu'aucun autre système ne permet à ce jour.The design, access security and controls (compulsory for all handling of lifting gear) that allow the present invention, thus provide a device for fast washing careening "self service" that no other system allows to this day.
On pourrait citer d' autres avantages à la présente invention mais ceux cités ci-dessus en montrent déjà suffisamment pour en prouver la nouveauté et l'intérêt. La description et les dessins ci-joints représentent un exemple de la réalisation de l'invention pour une utilisation avec des bateaux de plaisance mais n'ont aucun caractère limitatif : d'autres réalisations sont possibles dans le cadre de la portée et de l'étendue de cette invention, en particulier en changeant les moyens de supports et de translation verticale, et/ou le système de guidage de cette translation.Other advantages to the present invention could be mentioned but those mentioned above already show enough to prove novelty and interest. The description and the accompanying drawings represent an example of the embodiment of the invention for use with pleasure craft but are not limiting in nature: other embodiments are possible within the scope and scope of the invention. the scope of this invention, in particular by changing the means of support and vertical translation, and / or the guide system of this translation.

La figure 7 est une vue latérale de l'ensemble du dock et du bateau en position émergée telle que suivant les figures 5 et 6.Figure 7 is a side view of the entire dock and boat in emergent position as in Figures 5 and 6.
Tel que déjà présenté précédemment le dock maritime, fluvial ou lacustre tel que représenté sur les figures jointes, et permettant le relevage de structure flottante 7 telle qu'un bateau qui est l'exemple retenu dans la présente description, comprend un plateau caisson 1 immergeable apte à supporter ladite structure flottante 7.As already presented above the maritime dock, fluvial or lacustrine as shown in the accompanying figures, and allowing the lifting of floating structure 7 such as a boat which is the example used in the present description, comprises a submergible caisson plate 1 adapted to support said floating structure 7.
Des moyens supports de translation verticale sont aptes à émerger et immerger ledit plateau caisson 1 : suivant les modes de représentation des figures jointes ces moyens sont des ballasts 2 aptes à recevoir soit du gaz pour émerger le plateau caisson 1 soit de l'eau pour immerger celui-ci ; ces ballasts 2 peuvent être des volumes rigides en forme de cloche montés sur un châssis lourd en profilés métalliques supportant le plateau 1 mais peuvent être également des réservoirs souples.Vertical translation support means are able to emerge and immerse said caisson plate 1: according to the modes of representation of the accompanying figures, these means are ballasts 2 adapted to receive either gas to emerge the caisson plate 1 or water to immerse. this one ; these ballasts 2 can be rigid volumes in the form of bell mounted on a heavy frame of metal profiles supporting the plate 1 but can also be flexible tanks.
La chasse de l'eau dans lesdits ballasts 2 par au moins une ouverture, qui peut être la totalité de leur surface inférieure pour des volumes en forme de cloche, est effectuée par alimentation, telle que par pompage, en légère surpression au moins par rapport à la pression ambiante, de gaz, tel que de préférence l'air, dans les ballasts afin d'en chasser l'eau, et réciproquement le remplissage en eau de ces ballasts est effectué par simple purge du dit gaz ou de l'air.The flushing of the water in said ballast tanks 2 by at least one opening, which may be the whole of their bottom surface for bell-shaped volumes, is effected by feeding, such as by pumping, a slight overpressure at least in relation to at ambient pressure, of gas, such as preferably air, in the ballast tanks in order to expel the water, and conversely the filling of these ballast water is carried out by simply purging said gas or air .
Dans d'autres modes de réalisation lesdits moyens supports et de translation verticale peuvent être des mâts intégrant une transmission à déplacement linéaire,
tels que des vérins télescopiques ou mâts à crémaillères ou à chaînes, et ceux-ci du fait de leur rigidité verticale peuvent former alors également au moins une partie du système de guidage.In other embodiments, said support and vertical translation means may be masts incorporating a linear displacement transmission, such as telescopic cylinders or racks or chains, and these because of their vertical stiffness can then also form at least a portion of the guide system.
Suivant les modes de représentation des figures jointes, le système de guidage, lors de la translation verticale du dock, est constitué d'au moins deux poutres articulées 3 reliées chacune à une de leur extrémité à un élément de fondation 4, tels que des plots en béton, de type corps morts de grande masse, reposant sur le fond 10 du bassin proche du quai d'accès 8, et à l'autre extrémité au plateau caisson l' : ces poutres 5 formant avec celui-ci des parallélogrammes variables maintenant l'horizontalité de la structure flottante qui est pris en charge par le dock. Pour une meilleure stabilité il peut être utilisé, comme- représenté sur les figures, deux séries de deux poutres articulées 5 afin de constituer un parallélépipède rectangle ayant quatre arêtes verticales inclinées ; ces poutres articulées assurent la liaison et la stabilité avec le sol 10.According to the modes of representation of the attached figures, the guide system, during the vertical translation of the dock, consists of at least two articulated beams 3 each connected at one end to a foundation element 4, such as studs. concrete type body tonnage dead, resting on the bottom 10 of the basin near the dock access 8, and at the other end to the housing plate l ': these beams 5 forming therewith variable parallelograms now the horizontality of the floating structure that is supported by the dock. For better stability it can be used, as shown in the figures, two sets of two articulated beams 5 to form a rectangular parallelepiped having four inclined vertical edges; these articulated beams provide the link and the stability with the ground 10.
Au-dessus du plateau caisson 1 au moins deux jambes semi-flottantes 5 sont articulées à leur extrémité inférieure sur le plateau caisson 1 et leur extrémité supérieure est apte à prendre appui sur une partie de la surface de ladite structure flottante 7, ou bateau, de telle façon que celle-ci reste dans la même position pendant la phase d' émersion du dock : pour cela des plots de contact ou patins 12 sont articulés selon deux plans et orientables selon un axe en translation, faisant évoluer la surface de contact par rotation sans glissement tout en gardant l'alignement des contraintes de charge de chaque jambe 5.
Quand le dock est en position immergée telle que sur la figure 1 et le bateau 7 en approche lesdites jambes 5 sont ainsi verticales par leur propre flottabilité et quand le bateau 7 avance sur le dock tel que représenté sur la figure 3, suivant deux profils de coque 7 différents, les jambes 5 s'inclinent avec la poussée des coques 7 ; puis quand le dock est relevé ses jambes 5 continuent de s'incliner jusqu'à venir en butée 13 afin d' immobiliser les coques 7 à une hauteur prédéterminée par rapport au plateau caisson 1 sans qu' aucune partie de la coque telle que la quille ne puisse reposer sur ledit plateau.Above the caisson plate 1 at least two semi-floating legs 5 are hinged at their lower end on the caisson plate 1 and their upper end is able to bear on a part of the surface of said floating structure 7, or boat, so that it remains in the same position during the phase of emergence of the dock: for this contact pads or pads 12 are articulated in two planes and rotatable along an axis in translation, making the contact surface evolve by rotation without sliding while keeping the alignment of the load constraints of each leg 5. When the dock is in the submerged position as in FIG. 1 and the boat 7 approaching, said legs 5 are thus vertical by their own buoyancy and when the boat 7 advances on the dock as represented in FIG. 3, following two profiles of 7 different hull, legs 5 bow with thrust of hulls 7; then when the dock is raised its legs 5 continue to bow until abutting 13 to immobilize the hulls 7 at a predetermined height relative to the box tray 1 without any part of the hull such as the keel can not rest on said tray.
De plus le dock suivant l'invention comporte au moins une passerelle 6 flottante à la latitude contrôlée, c'est-à-dire pouvant se déplacer d'une manière contrôlée latéralement par rapport à l'axe d'approche du bateau 7, et de préférence deux passerelles pour être disposées de part et d'autre de la structure flottante, et reliée chacune au moins à une de leur extrémité à un accès piétons tel que le quai 8 d'un port : cette ou ces passerelles est/sont maintenues au-dessus du plateau caisson 1 en position immergée telle que représenté sur la figure 4 ; elles matérialisent ainsi l'axe d'approche que doit suivre le pilote du bateau ou de la structure flottante et sont aptes ainsi au guidage de la structure flottante pour qu'elle se positionne correctement au- dessus du plateau 1 : le bateau 7 est ainsi guidé par rapport à ces passerelles β en s' engageant entre elles jusqu'à des repères prédéterminés suivant le type de navire afin d'être bien positionné par rapport aux jambes semi-flottantes 5 ; ces passerelles 6 permettent ensuite en plus, en deuxième fonction, l'accès à pied d'une part
au quai 8 et d'autre part réciproquement du quai 8 vers la structure flottante 7.In addition, the dock according to the invention comprises at least one floating gateway 6 at the controlled latitude, that is to say able to move in a controlled manner laterally with respect to the approach axis of the boat 7, and preferably two bridges to be arranged on either side of the floating structure, and each connected at least one of their end to a pedestrian access such as the dock 8 of a port: this or these bridges is / are maintained above the box tray 1 in the submerged position as shown in Figure 4; they thus materialize the approach axis that must be followed by the pilot of the boat or the floating structure and are thus able to guide the floating structure so that it is positioned correctly above the plate 1: the boat 7 is thus guided with respect to these β bridges by engaging between them to predetermined landmarks depending on the type of ship to be well positioned relative to semi-floating legs 5; these bridges 6 then in addition, in second function, access on foot on the one hand at the platform 8 and at the other end of the platform 8 to the floating structure 7.
Au moins deux guides écarteurs inclinés 11 et de préférence deux séries de deux, sont fixés sur un côté du plateau caisson et s' élevant au-dessus de la surface de celui-ci : ils sont disposés en position immergée sous ladite passerelle flottante 6. Il peut être envisagé que ces guides écarteurs soient montés en sens inverse sur les passerelles.At least two inclined retracting guides 11 and preferably two sets of two, are fixed on one side of the box tray and rising above the surface thereof: they are arranged in submerged position under said floating bridge 6. It may be envisaged that these spacer guides are mounted in opposite directions on the bridges.
Ainsi lors de l'émersion du plateau caisson 1 et des ballasts 2 lesdits guides écarteurs 11 poussent les passerelles β vers l'extérieur (ou en sens inverse c'est le plateau caisson 1 qui pousse les guides écarteurs quand ceux-ci sont montés sur les passerelles) jusqu'à ce qu'elles soient positionnées de part et d'autre du plateau caisson 1 émergé, tel que représentée sur les figures 5 et 6, complétant l'aire ainsi disponible pour le carénage et le lavage de la coque du bateau 7, formant même un marche pied pratique pour accéder au franc bord du bateau.Thus, during the emergence of the caisson plate 1 and the ballasts 2, said spreader guides 11 push the bridges β outwards (or in the opposite direction it is the caisson plate 1 which pushes the spacer guides when they are mounted on the bridges) until they are positioned on either side of the caisson plate 1 emerged, as shown in Figures 5 and 6, completing the area thus available for the fairing and washing of the hull of the boat 7, forming even a walk convenient walk to access the freeboard of the boat.
Cette opération peut être simplement commandée depuis un bloc technique de commande 9 situé sur le quai 8 auquel le skipper du bateau accède grâce à la passerelle 6. Grâce à tout moyen de paiement tel que par jetons, ou autres, délivrés par la capitainerie du port, l'utilisateur enclenche alors la commande de montée qui a pour effet de chasser l'air des caissons immergés et donc de faire émerger le dock avec le bateau 7.This operation can be simply ordered from a technical control unit 9 located on the platform 8 to which the skipper of the boat accesses through the bridge 6. Through any means of payment such as tokens, or others, issued by the Harbor Master's Office , the user then triggers the climb control which has the effect of driving the air out of the submerged caissons and thus to make the dock emerge with the boat 7.
Le bloc technique 9 qui peut être en plusieurs parties, l'une pouvant être semi-immergé pour certains équipements et l'autre disposée sur le quai, comprend les organes fonctionnels de l'ouvrage tels qu'un compresseur d'air d'alimentation des ballasts, une pompe de reprise
des effluents et de matière s' écoulant par un conduit depuis un orifice 14 situé au point le plus bas du plateau caisson 1 une fois émergé vers une fosse de traitement intégral autonome des effluents, un bloc de lavage haute pression et tous les dispositifs de commande et de manœuvre des différentes phases d'utilisation du dock et des appareils ci-dessus. Un tel dispositif évite tout rejet dans les eaux environnantes et préserve la qualité de celles-ci.The technical block 9 which can be in several parts, one of which can be semi-immersed for certain equipment and the other arranged on the platform, comprises the functional components of the structure such as a supply air compressor ballasts, a recovery pump effluent and material flowing through a conduit from an orifice 14 located at the lowest point of the caisson tray 1 once emerged to an integral integral effluent treatment tank, a high pressure wash block and all control devices and maneuvering the different phases of use of the dock and the above devices. Such a device avoids any discharge into the surrounding waters and preserves the quality thereof.
L'encombrement total d'un dock suivant l'invention utilisé pour le carénage rapide et le lavage de bateau de 5 à 14 mètres de longueur peut être de l'ordre de 10 mètres de long pour 4 mètres de large avec une amplitude de relevage de 2 à 3 mètres selon le fond.The total size of a dock according to the invention used for the fast fairing and the boat wash of 5 to 14 meters in length can be of the order of 10 meters long and 4 meters wide with a lifting amplitude from 2 to 3 meters depending on the background.
Une fois l'opération de carénage et de lavage effectuée l'opérateur déclenche la manœuvre de descente depuis la borne de commande 9 et en quelques minutes le bateau 7 se retrouve de nouveau à flot avec les passerelles flottantes 6 reprenant leur position en se rapprochant l'une de l'autre vers la coque du bateau 1, du fait de leur latitude contrôlée grâce en particulier aux deux guides écarteurs inclinés 11 et à tout moyen de rappel. Le plaisancier remonte ainsi à bord de son navire par lesdites passerelles 6 et libère le dock pour l'utilisateur suivant, l'ensemble des opérations ayant pu représenter un total de l'ordre de 30 minutes environ.
Once the fairing and washing operation has been carried out, the operator triggers the descent maneuver from the control terminal 9 and in a few minutes the boat 7 is again afloat with the floating bridges 6 resuming their position while approaching the lighthouse. from one to the other towards the hull of the boat 1, because of their controlled latitude thanks in particular to the two inclined retracting guides 11 and to any return means. The boater goes back aboard his ship by said bridges 6 and frees the dock for the next user, all operations could have been a total of about 30 minutes.
