Description
La présente invention concerne un dispositif permettant à toute structure flottante évoluant en milieu aquatique, de se retrouver hors d’eau en prenant appuis sur le fond grâce à un système de pilotis rétractables fixé à la coque. Le dispositif selon l’invention est conçu d’une part pour permettre aux occupants d’éviter les désagréments du tangage ou du roulis dus aux vagues, aux vents et aux courants et d’autre part pour diminuer les risques de décrochages des ancres tout en ralentissant la détérioration de la coque qui ne se trouve alors plus immergée. Cette invention permet également de changer aisément et rapidement de zone d’implantation grâce à un système de rétractation des pilotis très simple d’utilisation.The present invention relates to a device allowing any floating structure evolving in an aquatic environment, to find itself out of the water by taking support on the bottom thanks to a system of retractable pilings fixed to the hull. The device according to the invention is designed on the one hand to allow the occupants to avoid the inconveniences of pitching or rolling due to waves, winds and currents and on the other hand to reduce the risk of unhooking the anchors while slowing down the deterioration of the hull, which is then no longer submerged. This invention also makes it possible to easily and quickly change the installation area thanks to a very easy-to-use pile retraction system.
Selon un mode de réalisation, le dispositif de pilotis rétractables pour structure flottante est composé de pilotis constitués par des vérins (1), dont les corps (2) sont incorporés à la coque (3) de la structure flottante de telle manière que les tiges (4) des vérins puissent coulisser verticalement à l’aide d’un système de commande programmable (5), soit en poussée contre le fond pour mettre hors d’eau la structure flottante, soit en traction pour la remettre à flot, lesquelles tiges sont chacune munies d’une plaque circulaire servant de sabot (6) afin d’éviter à l’ensemble de s’enfoncer dans le sol et sur laquelle peuvent être fixées des extrémités amovibles optionnelles (9 et 10).According to one embodiment, the device for retractable pilings for a floating structure is composed of pilings consisting of jacks (1), whose bodies (2) are incorporated into the hull (3) of the floating structure in such a way that the rods (4) cylinders can slide vertically with the aid of a programmable control system (5), either by pushing against the bottom to put the floating structure out of the water, or by pulling to put it back afloat, which rods are each provided with a circular plate serving as a shoe (6) in order to prevent the assembly from sinking into the ground and on which optional removable ends (9 and 10) can be fixed.
Selon un mode de réalisation, les vérins (1) de type à vis sans fin, dont les tiges (4) sont en acier inoxydable, sont motorisés tout en pouvant être actionnés mécaniquement en cas de défaillance des moteurs (8).According to one embodiment, the jacks (1) of the worm screw type, the rods (4) of which are made of stainless steel, are motorized while being able to be actuated mechanically in the event of failure of the motors (8).
Selon la préférence, les pilotis sont constitués par un système de vérins à vis sans fin (1) ou à crémaillère, ou de vérins hydrauliques à huile ou à air ou à pression de l’eau, pouvant être télescopique, dont le corps (2) est fixé à l’intérieur de la coque (3) grâce à des fixations boulonnables (7) ou par soudure, de telle manière que la tige (4) puisse coulisser verticalement. La tige devra avoir une longueur suffisante pour pouvoir atteindre la profondeur voulue et une épaisseur permettant de résister aux contraintes de poids et de torsion.Depending on preference, the piles are made up of a system of worm (1) or rack-and-pinion jacks, or hydraulic oil or air or water pressure jacks, which can be telescopic, whose body (2 ) is fixed inside the hull (3) by boltable fasteners (7) or by welding, so that the rod (4) can slide vertically. The rod should be long enough to reach the desired depth and thick enough to withstand weight and torsion stresses.
Selon la préférence, le système de commande est un ordinateur (5) ayant une programmation permettant d’une part la descente des tiges (4) de manière indépendante jusqu’au contact avec le sol, puis permettant d’autre part la synchronisation des vérins lors de leur poussée contre le sol (II) ou de leur rétractation (I) afin de mettre hors d’eau ou à flot la structure flottante de manière que celle-ci reste toujours en position horizontale pendant les translations verticales qui seront régulières et sans à-coups.According to preference, the control system is a computer (5) having programming allowing on the one hand the descent of the rods (4) independently until contact with the ground, then allowing on the other hand the synchronization of the cylinders during their thrust against the ground (II) or their retraction (I) in order to put the floating structure out of the water or afloat so that it always remains in a horizontal position during the vertical translations which will be regular and without jerks.
Les vérins sont actionnés au choix par des moteurs incorporés électriques (8) ou thermiques, ou par un système mécanique ou manuel et sont reliés entre eux à l’aide d’un câble (11) à un dispositif de commande électronique, pouvant être un ordinateur (5) muni d’un programme adapté ou d’un boitier de commande programmable, permettant à la structure de se lever de manière synchronisée afin que les contraintes de poids soient équilibrées et que l’ensemble puisse monter ou descendre à l’horizontal à la hauteur choisie.The cylinders are actuated either by electric (8) or thermal incorporated motors, or by a mechanical or manual system and are interconnected by means of a cable (11) to an electronic control device, which can be a computer (5) equipped with a suitable program or a programmable control box, allowing the structure to rise in a synchronized manner so that the weight constraints are balanced and the assembly can rise or fall horizontally at the chosen height.
Selon la préférence, à l’extrémité de chaque tige de vérin se trouve une plaque circulaire servant de sabot (6), conçue de manière à pouvoir accueillir des accessoires interchangeables adaptés selon la nature des fonds rencontrés et l’utilisation désirée. Cette plaque circulaire est constituée de trous permettant d’y fixer les accessoires à l’aide de boulons.According to preference, at the end of each cylinder rod is a circular plate serving as a shoe (6), designed to accommodate interchangeable accessories adapted according to the nature of the bottoms encountered and the desired use. This circular plate is made up of holes for attaching accessories to it using bolts.
Selon la préférence, un des accessoires interchangeables peut être une roue pivotante escamotable (9) de type roue de caddie qui permet en cas de besoin de déplacer la structure en la tractant sur terre.According to preference, one of the interchangeable accessories can be a retractable pivoting wheel (9) of the trolley wheel type which, if necessary, makes it possible to move the structure by towing it on land.
Une autre préférence dans le cas des sols meubles de mangrove peut être une extrémité en forme de vis (10) de type vis de tarière qui permettra à la structure de se fixer dans le sol à une profondeur déterminée grâce au mouvement circulaire descendant des pilotis.Another preference in the case of soft mangrove soils can be an end in the form of a screw (10) of the auger screw type which will allow the structure to be fixed in the ground at a determined depth thanks to the downward circular movement of the pilings.
Le dispositif est composé d’au moins quatre vérins placés aux extrémités de la coque, ou plus si celle-ci possède une portance plus grande de façon à bien équilibrer la charge. Suivant le type d’embarcation proposé, le dispositif sera soit fixé sur l’extérieur de la coque au-dessus de la ligne de flottaison (dans le cas d’un bateau), soit incorporée à l’intérieur de la coque à l’aide de fixations boulonnables (7) ou par soudure après qu’elle ait subi certaines modifications structurelles permettant l’installation des pilotis et l’immersion de leurs tiges avec une parfaite étanchéité.The device is made up of at least four cylinders placed at the ends of the hull, or more if the latter has greater lift in order to properly balance the load. Depending on the type of boat proposed, the device will either be fixed on the outside of the hull above the waterline (in the case of a boat), or incorporated inside the hull at the using boltable fasteners (7) or by welding after it has undergone certain structural modifications allowing the installation of piles and the immersion of their rods with perfect sealing.
Le programme mentionné permet également d’adapter la poussée des vérins en fonction des irrégularités des fonds et des différences de profondeurs. Ainsi, les pilotis descendent librement jusqu’à ce qu’ils soient en contact avec le fond, c’est alors que la poussée s’enclenche.The program mentioned also makes it possible to adapt the thrust of the cylinders according to the irregularities of the bottom and the differences in depth. Thus, the pilings descend freely until they are in contact with the bottom, this is when the thrust engages.
Le dispositif permet également d’actionner les vérins manuellement à l’aide d’une manivelle dans le cas d’une défaillance de leurs moteurs.The device also makes it possible to actuate the cylinders manually using a crank in the event of a failure of their motors.
Les vérins sont sélectionnés de façon à ce qu’ils puissent supporter une poussée nettement supérieure à celle nécessaire pour lever la structure à vide.The jacks are selected so that they can withstand a much greater thrust than that required to lift the structure when empty.
L’intérêt de cette invention est qu’elle ouvre de nouvelles perspectives car elle permet à des habitations flottantes ainsi qu’à leurs habitants de s’installer de manière stable et durable dans des zones pouvant être exposées à la houle, aux vents et aux courants, cela sur des fonds sableux (bord des plages, hauts fonds, fonds blancs, zones de fortes marées, etc…), sans risquer de déraper ou d’endommager les fonds marins comme avec un mouillage classique.The advantage of this invention is that it opens up new perspectives because it allows floating dwellings and their inhabitants to settle in a stable and sustainable manner in areas that may be exposed to swells, winds and currents, this on sandy bottoms (beach edges, shallows, white bottoms, areas of high tides, etc.), without the risk of skidding or damaging the seabed as with a conventional anchorage.
De plus, la présente invention offre la possibilité, grâce à son système de pilotis rétractables rapide et simple d’utilisation décrit ci-dessus, de se déplacer aisément d’une zone à l’autre en cas de nécessité.In addition, the present invention offers the possibility, thanks to its quick and easy-to-use retractable piling system described above, to move easily from one area to another if necessary.
