Le maintien en tension du s'effectue soit par un second câble (5b) guidé par des poulies(6) fixées au sommet des poteaux métalliques et sur les pontons qui forme un second palan et peut produire lui-même de l'énergie ; soit en cas d'impossibilité technique par un contre poids ou un système de tension mécanique ou électrique.

Maintaining tension is performed by a second cable (5b) guided by pulleys (6) fixed to the top of the metal poles and on the pontoons which forms a second hoist and can itself produce energy; or in case of technical impossibility by a counterweight or mechanical or electrical tension system. This device makes it possible to exploit the energy of the tides in the form of electricity or compressed gas all the year away from waves and waves without any impact on the environment.
Description
Système de récupération de l'énergie des marées en utilisant les structures flottantes des ports. Système permettant de transformer les structures existantes d'un port de plaisance ou les structures desservant d'autres type de bateaux (pêche pilotines remorqueurs bacs etc...) en centrale de récupération de l'énergie des marées Ce système concerne les ports soumis à des coefficients de marée significatifs. Pour cela il faut utiliser les structures en place c'est-à-dire les pontons(1) qui desservent les bateaux à quai. Les pontons des ports de plaisance sont flottants et leur mouvement de haut en bas s'effectue grâce à la marée en coulissant le long de poteaux métalliques(3) fixés au fond du bassin. Grace à un système de câbles(5a) et de poulies(6) on peut récupérer l'énergie 15 de la marée montante en connectant un générateur d'électricité en bout de quai au câble. Pour ce faire il faut fixer les poulies sur les pontons et placer sous chaque ponton un lest en béton ou autre matière posé au fond sur lequel viendra également se fixer des poulies. Ensuite un câble viendra relier chacune des 20 poulies afin de former un grand palan. Enfin le câble sera connecté à un générateur d'électricité. Ainsi lors de la marée montante les pontons vont remonter vers le haut sous la poussée d'Archimède produite par leurs flotteurs, le câble va se dérouler et entrainer le générateur d'électricité(7) et ainsi produire de l'énergie. (Fig 1 et 2) 25 Si l'on veut garder l'énergie, on peut également utiliser à la place du générateur un compresseur d'air ou d'autre gaz ou fluide qui pourra restituer ultérieurement l'énergie comprimé ainsi accumulé dans des réservoirs prévus à cet effet. Lors de la marée descendante, c'est le poids de la structure qui va permettre à 5 un deuxième circuit de câble(5b), cette fois ci installé sur les pieux métalliques qui va à la fois produire de l'énergie en utilisant la gravité et rembobiner l'autre circuit de câble. On peut relier les deux circuits de câble si besoin et n'utiliser qu'un seul câble. En cas d'impossibilité technique de cette dernière solution, on peut mettre en 10 lieu et place un contre poids qui maintient le câble en tension ou un système de rappel qui soit mécaniquement ou électriquement maintient le câble en tension. S'il en est besoin la flottabilité des éléments flottants peut être renforcée à l'aide de boudins gonflables.Tidal energy recovery system using the floating structures of the ports. System for transforming the existing structures of a marina or structures serving other types of boats (fishing tugs piers traps etc ...) in tidal energy recovery plant This system concerns the ports subject to significant tidal coefficients. For this it is necessary to use the structures in place that is to say the pontoons (1) which serve the boats at the dock. The pontoons of the marinas are floating and their movement up and down is effected by the tide by sliding along metal poles (3) fixed to the bottom of the basin. Thanks to a system of cables (5a) and pulleys (6), the energy of the rising tide can be recovered by connecting an electricity generator at the end of the platform to the cable. To do this we must fix the pulleys on the pontoons and place under each pontoon ballast concrete or other material placed at the bottom on which will also fix pulleys. Then a cable will connect each of the pulleys to form a large hoist. Finally the cable will be connected to an electricity generator. Thus during the rising tide the pontoons will rise upward under the buoyancy force produced by their floats, the cable will unfold and cause the generator of electricity (7) and thus produce energy. (FIGS. 1 and 2) If it is desired to keep the energy, it is also possible to use an air compressor or other gas or fluid in the place of the generator, which can subsequently restore the compressed energy thus accumulated in tanks provided for this purpose. During the ebb tide, it is the weight of the structure that will allow a second cable circuit (5b), this time installed on the metal piles that will both produce energy using gravity. and rewind the other cable circuit. The two cable circuits can be connected if necessary and use only one cable. In case of technical impossibility of this last solution, it is possible to put in place and place a counterweight which keeps the cable in tension or a return system which is mechanically or electrically keeps the cable in tension. If it is needed the buoyancy of the floating elements can be reinforced by means of inflatable tubes.
15 Cette énergie a l'avantage d'être prévisible et mesurable avec précision car on connait avec exactitude l'amplitude des marées dans chacun des ports et la flottabilité théorique de chacun de pontons. Ainsi on sait exactement quel va être le mouvement des pontons et on peut gérer l'énergie apportée par ce biais en pilotant électroniquement le générateur. 20 la mise en place des structures s'appuie sur des éléments existants d'un coût moins élevé que la construction d'une structure dédiée comme par exemple un flotteur spécifique ou une éolienne. Ce type d'énergie marémotrice est propre et sans conséquence sur la planète dans la mesure les forces s'exercent de bas en haut contrairement aux 25 centrales marémotrices classiques qui impactent de façon infinitésimale la rotation terrestre.This energy has the advantage of being predictable and measurable precisely because the magnitude of the tides in each of the ports and the theoretical buoyancy of each pontoons are accurately known. So we know exactly what will be the movement of the pontoons and we can manage the energy provided by this way by electronically controlling the generator. The establishment of the structures relies on existing elements of a lower cost than the construction of a dedicated structure such as a specific float or a wind turbine. This type of tidal energy is clean and of no consequence on the planet as the forces are exerted from the bottom up unlike the 25 conventional tidal power plants which have an infinitesimal impact on the Earth's rotation.
