Abstract

The element (1) has a ballast (3) fixed at a lower end of a mast (2). An immersed semi vertical front strip is supported by the element. A collecting device is in a form of tank supported by the element, where the collecting device is provided with a floating barrier (4). Weight of the element, the ballast and volume of selected buoys condition a level of immersion and stability of the element. Four branches of a cross allow fixing of the buoys at ends of the element.

Description

-- Pour la construction de barrages flottants en mer, les difficultés sont principalement dues à un environnement hostile (houle, vagues, vent). De ce fait, il est difficile de réaliser des barrages stables et de hauteur suffisante pour être réellement efficaces et aptes à résister aux éléments. Le dispositif décrit ci après répond à cette problématique. - For the construction of floating dams at sea, the difficulties are mainly due to a hostile environment (swell, waves, wind). As a result, it is difficult to achieve stable dams of sufficient height to be truly effective and resistant to the elements. The device described below responds to this problem.

Au cours des recherches effectuées, j'ai constaté que, s'il existe des procédés de contention et de récupération de polluants, ceux-ci sont : soit extrêmement légers et peu appropriés à la haute mer, soit au contraire extrêmement lourds tant dans leur fabrication que dans leur mise en service. Il n'a, en outre, pas été trouvé de dispositif semblable à celui proposé. During the research carried out, I noticed that, if there are methods of compression and recovery of pollutants, these are: either extremely light and not very suitable for the high seas, or on the contrary extremely heavy both in their manufacture only in their commissioning. In addition, no device similar to that proposed was found.

Le dispositif inventé, objet de la présente demande, offre une solution à ce qui précède, par sa fabrication aisée (d'où coût peu élevé) comme par sa facilité d'installation et de mise en oeuvre sur site. Dans son ensemble, il est composé d'éléments flottants destinés à supporter un bandeau vertical partiellement immergé, ce bandeau devant contenir et canaliser les polluants Les problématiques étant la hauteur utile de ce bandeau et les proportions de ses parties émergées et immergées ainsi que la stabilité de l'ensemble, ce dispositif y répond. Elément flottant supportant un mât : Sommairement, il est composé d'une croix horizontale, sur laquelle, à l'extrémité de chaque branche, de longueur égale, est fixée une bouée. Au centre de la croix, un axe vertical la traverse, dans lequel s'insère un mât qui peut être réglable en hauteur par coulissement. A l'extrémité inférieure du mât, un lest. En fonction du volume des bouées utilisées, du poids du dispositif et de son lest, la majeure partie de l'élément est plus ou moins immergée, laissant hors d'eau la partie supérieure du mât. L'ensemble, au centre de gravité bas, est particulièrement stable, pratiquement inchavirable et le mât reste toujours perpendiculaire à la surface de l'eau. Si nécessaire, l'axe peut être renforcé aux points de jonction de chaque bras et du mât. L'élément central (hors les bouées) peut être fabriqué dans des matériaux divers : métal, matière plastique ou composite. Il peut être d'une seule pièce ou montable-démontable, cette dernière solution offrant le plus de facilité en ce qui concerne le stockage, la manutention et surtout l'utilisation (montage en mer avant mise à l'eau) En fonction de sa destination, il peut être de toutes sortes de tailles qui conditionneront également le volume des bouées à utiliser (bouées gonflées ou pleines) Ces tailles sont elles-mêmes conditionnées par l'usage escompté. (type de polluant, surfaces à traiter, environnement) A partir de cet élément flottant, toutes sortes d'applications sont réalisables : barrage flottant, bien sur, donc contention d'un polluant, mais aussi captation, traction sur l'eau et récupération de ce même polluant, réalisation de pontons, de chaland ou de barges, ou encore flottaison d'équipement lourd. 2960512 -2- Un barrage flottant pourra être constitué d'un bandeau vertical semi immergé s'accrochant sur les éléments flottants. Ce bandeau pourra être complètement étanche en cas de polluants fluides ou visqueux. II pourra, en revanche être constitué d'un filet ne récoltant que des polluants d'un certain diamètre. L'ensemble du barrage pourra être tracté par 5 bateau pour capter et emprisonner une nappe. II pourra être arrimé tout ou partiellement sur des « corps morts » ou des ancres. Parmi les composants du barrage, un dispositif de captage de la pollution. Une fois contenu et concentré par la forme, la tension exercée et le déplacement du barrage, les polluants pourront être recueillis par un dispositif dont les réglages en hauteur permettent de n'aspirer que l'épaisseur de liquide indispensable. (Voir 10 figures) Enfin, l'usinage des axes, des bras et des mâts est facile et peu coûteuse. Les axes peuvent être fabriqués par soudure ou par moulage. Les figures annexées permettront de mieux comprendre le principe : Figure 1 - Vue en plan schématique : Axe du mât coulissant (1) 15 Figure 2 - Vue de profil : Axe du mât (1) - Anneaux de fixation aux extrémités des bras (2) - Anneau de fixation du lest (3) - Lest (4) Figure 3 - Vue de profil : Fabrication fixe, soudée, le mât n'est pas réglable en hauteur.

The invented device, object of the present application, offers a solution to the above, by its easy manufacture (hence low cost) as well as its ease of installation and implementation on site. As a whole, it is composed of floating elements intended to support a vertical strip partially immersed, this band to contain and channel the pollutants The problems being the useful height of this strip and the proportions of its emerged and immersed parts as well as the stability overall, this device responds. Floating element supporting a mast: Briefly, it is composed of a horizontal cross, on which, at the end of each branch, of equal length, is fixed a buoy. In the center of the cross, a vertical axis crosses it, in which a mast is inserted which can be adjustable in height by sliding. At the lower end of the mast, a ballast. Depending on the volume of buoys used, the weight of the device and its ballast, most of the element is more or less submerged, leaving the upper part of the mast out of water. The whole, at the low center of gravity, is particularly stable, practically self-reinforcing and the mast always remains perpendicular to the surface of the water. If necessary, the axis can be reinforced at the junction points of each arm and the mast. The central element (excluding the buoys) can be made of various materials: metal, plastic or composite. It can be of one piece or mountable-dismountable, the latter solution offering the most ease in terms of storage, handling and especially the use (assembly at sea before launching) According to its destination, it can be of all kinds of sizes that will also determine the volume of buoys to use (inflated buoys or full) These sizes are themselves conditioned by the expected use. (type of pollutant, surfaces to be treated, environment) From this floating element, all kinds of applications are possible: floating dam, of course, therefore containment of a pollutant, but also capture, traction on the water and recovery of this same pollutant, construction of pontoons, barges or barges, or floating of heavy equipment. A floating dam may consist of a semi-immersed vertical strip hanging on the floating elements. This headband can be completely waterproof in case of fluid or viscous pollutants. On the other hand, it may consist of a net collecting only pollutants of a certain diameter. The entire dam can be towed by boat to capture and trap a tablecloth. It may be stowed in whole or in part on "dead bodies" or anchors. Among the components of the dam, a device for collecting pollution. Once contained and concentrated by the form, the tension exerted and the displacement of the dam, the pollutants can be collected by a device whose height adjustments make it possible to aspire only the thickness of essential liquid. (See 10 figures) Finally, the machining of axes, arms and masts is easy and inexpensive. The axes can be manufactured by welding or molding. The appended figures will make it easier to understand the principle: Figure 1 - Diagrammatic plan view: Sliding mast shaft (1) 15 Figure 2 - Profile view: Mast axis (1) - Attachment rings at the ends of the arms (2) - Ballast fixing ring (3) - Ballast (4) Figure 3 - Side view: Fixed, welded construction, the mast is not adjustable in height.
