Description

- Page 1 - Engin maritime de positionnement en pélagique, des récupérateurs d'énergie marine (turbines hydroélectriques) Cet ensemble de câbles, orins, planches (type planches de chalut) bouées et corps-morts, est destiné à recevoir l'accrochage d'engins maritimes, capables de récupérer 1 'énergie des courant marins. Cet ensemble sera positionné dans et sur le parcours d'un courant marin (fig 1- C et 2 C))(qu'il soit linéaire ou de marée) de façon à permettre à un engin capable de récupérer l'énergie des courants marins de travailler dans les meilleures conditions possibles, que ce soit en surface ou en pélagique, et quelles que soient les profondeurs marines qui existent au dessous des plages ou strates décidées pour cette récupération. Il est composé d'un corps-mort g 1-1, 1-1', 1-1", ou fig 2-1) d'importance suffisante, placé au centre géographique du lit du courant dans lequel on veut faire travailler les engins de récupération (fig 2-7). Sur ce corps-mort est fixé un câble (appelé orin) d'une longueur suffisante pour rejoindre la surface de la mer (g 1-2,1-2 ;1-2", ou (fig2-2) et recevoir ou non à sa partie supérieure une bouée (fig 2-3 et 2-3 )), un engin de récupération, ou (et) un ensemble de signalisation. A des points prédé anis cet orin recevra des points d'accrochage (fig 2-4) destinés à recevoir des élingues en acier(fig 3, figl) (ou tous autres matériaux) qui, reliées les unes aux autres par des points de jonction genre anneaux ou autres (fig 1- 5, fig 2- 5, fig 4), formeront des trames d'attaches superposées. A ces intersections nous pourrons fixer les appareils récupérateur de l'énergie du courant marin par l'intermédiaire d 'orins annexes, plus courts. Un gouvernail de profondeur sur chaque appareil (fig 2-6), permettra par une programmation, de faire travailler celui-ci : soit au niveau de la trame, soit au dessus, soit au dessous. Il est probable que ce pilotage sera asservi et piloté à partir d'une centrale d'assiette. Sur les cotés de la trame, seront fixés des ensembles orin + corps-mort (fig 1-7) qui assureront l'écartement de la trame. Il pourra aussi être fait usage, de façon alternative, de planches d'écartement (fig 1-8) genre planches de chalut. Des élingues transversales (fig 1-11) pourront être posées pour éviter un écartement irrégulier, et au moins aux points ou sont arrimés les corps-mort latéraux (fig 1,- 7 et 1 -10) mais leur nombre n 'est pas limité. Les élingues (fig 1-9) seront de longueur identiques (suivant leur 40 destination), mais de longueur indéfinie, étant adaptées en taille et en - 2- résistance aux types d'appareils de récupération d'énergie, qu 'elles auront à retenir. Des élingues longitudinales (fig 1-12) viendront répondre à la traction exercée par les appareils récupérateurs d'énergie. Il y aura 45 autant d'élingues longitudinales qu 'il sera nécessaire Ces élingues, pour faciliter le travail de mise en place et de maintenance, et aussi pour annuler leur poids par une poussée d'Archimède égale à leur poids, recevront un manchon en polyvinyle ou autre matière (fig 3-2) résistant à 1 'eau de mer, ce dit manchon sous 50 forme de tuyaux étant thermo-soudés (fig 3-3) sur les extrémités de l 'élingue (fig 3 -1). La trame (fig 1) sera de dimensions indéterminées. Elle sera extensible comme un mécano (si besoin est) sur toute la largeur utile d'un courant marin, par adjonction de nouvelles élingues et des 55 corps-mort appropriés. Il en est de même pour sa longueur, qui peut être infinie !!! Il suffira d'y mettre le nombre de corps-mort longitudinaux et latéraux nécessaires. Le nombre de trames (ou strates) n 'est théoriquement pas limité ! 60 Il le sera pourtant pour des raisons pratiques - étanchéité des engins de récupération d 'énergie - conditions de pose, d'accrochage, de maintenance du parc d'engins Mais comme sur le plan maritime nous ne serons pas limités par la 65 quantité des lieux exploitables (possibilités illimitées), il n ÿ aura pas lieu, dans l'état de la technique actuelle, d'augmenter la profondeur des plans de travail. Il est pensable, d'ailleurs, qu 'une seule strate soit utilisée. Il serait bien sur possible de donner d'autres formes géométriques à la trame avec par exemple une façade à plat, mais cela ne changerait 70 en rien le principe de travail de l'ensemble. Sur le plan de l'installation proprement dite, les corps-mort seront fixés aux orins directement à partir de la barge chargée de les installer, qui les laissera filer directement à l'endroit prévu de leur implantation. Toute 1 'installation de la trame sera montée au fur et à 75 mesure sur la barge, car toutes les longueurs d'élingues auront été prédéfinies. Des bouées provisoires seront placées aux intersections et enlevées lors de l'accrochage des engins récupérateur d'énergie. Il sera mis alors un lest qui viendra contrebalancer la traction du dit engin (ou le contraire s 'il est décidé de le faire travailler sous la trame g 2-6 ) 80 Il est vraisemblable que 1 'accrochage des engins de récupération d'énergie, ainsi que la maintenance (qui se fera sûrement par échange -3 standard) se fasse rapidement avec des robots. Mais comme la longueur des orins OEig 1-2, 1-2 , 1-" (et de tous les orins retenant la trame au fond de la mer) sera de 3 xl, c'est-à-dire 3 fois la profondeur d'eau à l'endroit 85 ou ils seront implantés, un remorqueur (fig 5) pourra très facilement faire remonter la trame et les engins de récupération de l'énergie pour des petites réparations. Mieux, pour des grosses réparations et pour les échange-standarts, le remorqueur tirera la barge qui elle se servira de sa grue pour mettre la seule partie à réparer sur le pont (fig 6) 90 Pièce mécano-soudée de raccordement polyvalente g 4) à la place des anneaux (fig 2-4 et 2-5). Raccordement des élingues à 1 'aide de manilles. Sens du courant : (fig 4-C) - Page 1 - Pelagic positioning marine machine, marine energy recuperators (hydroelectric turbines) This set of cables, orins, planks (trawl boards type) buoys and mooring, is intended to receive the attachment of maritime machines capable of recovering the energy of the marine currents. This set will be positioned in and on the course of a marine current (fig 1- C and 2 C)) (whether linear or tidal) so as to allow a machine capable of recovering the energy of marine currents to work in the best possible conditions, whether on the surface or in pelagic, and whatever the sea depths that exist below the beaches or strata decided for this recovery. It is composed of a dead body g 1-1, 1-1 ', 1-1 ", or fig 2-1) of sufficient importance, placed in the geographical center of the bed of the current in which one wants to make work the recovery gear (fig 2-7) On this mooring is fixed a cable (called orin) of sufficient length to reach the surface of the sea (g 1-2,1-2; 1-2 ", or (fig2-2) and receive or not at its upper part a buoy (Fig 2-3 and 2-3)), a recovery vehicle, or (and) a set of signaling. At predetermined points this rope will receive attachment points (fig 2-4) intended to receive steel slings (fig 3, figl) (or any other materials) which, connected to each other by junction points Like rings or others (fig 1- 5, fig 2- 5, fig 4), will form superimposed frames of fasteners. At these intersections we will be able to fix the recuperators of the energy of the marine current by means of annexed ores, shorter. A rudder on each device (fig 2-6) will allow programming to make it work: either at the level of the frame, or above or below. It is likely that this pilot will be enslaved and controlled from a central plate. On the sides of the frame, will be fixed orin + dead-body assemblies (fig 1-7) which will ensure the spacing of the frame. It may also be used, alternatively, spacers (Fig 1-8) like trawl boards. Cross slings (fig 1-11) may be placed to avoid irregular spacing, and at least at the points where the lateral dead bodies (fig 1, - 7 and 1 -10) are stowed, but their number is not limited. . The slings (FIG. 1-9) will be of identical length (depending on their destination), but of indefinite length, being adapted in size and in - 2- resistance to the types of energy recovery apparatus, which they will have to hold back. Longitudinal slings (fig 1-12) will respond to the tension exerted by energy recovery devices. There will be 45 as many longitudinal slings as will be needed These slings, to facilitate the work of setting up and maintenance, and also to cancel their weight by an Archimedes thrust equal to their weight, will receive a sleeve. polyvinyl or other material (Fig. 3-2) resistant to seawater, that said sleeve in the form of pipes being heat-welded (Fig. 3-3) on the ends of the sling (Fig. 3 -1). The frame (fig 1) will be of indeterminate dimensions. It will be stretchable as a mechanic (if necessary) over the full width of a marine current, by adding new slings and appropriate skips. It is the same for its length, which can be infinite! It will suffice to put there the number of longitudinal and lateral moorings necessary. The number of frames (or strata) is theoretically not limited! 60 It will be so for practical reasons - sealing of the energy recovery machines - conditions of installation, attachment, maintenance of the fleet of vehicles But as on the sea we will not be limited by the amount of exploitable places (unlimited possibilities), it will not be necessary, in the current state of the art, to increase the depth of the work plans. It is thinkable, moreover, that only one stratum is used. It would of course be possible to give other geometric shapes to the frame with for example a flat facade, but that would not change the working principle of the whole. In terms of the actual installation, the moorings will be attached to the ores directly from the barge responsible for installing them, which will let them go directly to the planned location of their implantation. Any installation of the frame will be mounted as and when measured on the barge, because all the lengths of slings have been predefined. Provisional buoys will be placed at intersections and removed when attaching energy recovery machines. It will be put then a ballast that will counteract the traction of the said machine (or the opposite if it is decided to make it work under the frame g 2-6) 80 It is likely that the attachment of the energy recovery machines , as well as maintenance (which will surely be done by exchange -3 standard) is done quickly with robots. But as the length of the ores OEIG 1-2, 1-2, 1- "(and of all the orins retaining the weft at the bottom of the sea) will be 3 xl, that is to say 3 times the depth d water at the place 85 where they will be installed, a tug (fig 5) will be able very easily to raise the frame and the machines of recuperation of the energy for small repairs, better, for major repairs and for the exchange- standarts, the tugboat will pull the barge which she will use her crane to put the only part to repair on the bridge (fig 6) 90 welded piece of polyvalent connection g 4) instead of the rings (fig 2-4 and 2-5) Connecting the slings with shackles Current direction: (fig 4-C)
