Pendant ce temps, la centrale hydroélectrique (CH) produit de l'énergie électrique, alimentée en eau par une conduite forcée (CF) venant du réservoir supérieur (RS), la sortie de l'eau se faisant directement dans le réservoir inférieur (RI).A system consisting of a propulsion portion and a production portion for utilizing sea pressure and tide during tides and waves to produce electrical energy. The propulsion part, installed at sea, consists of a base (B1) with a platform (P1) on which are installed two pumps (PM) and (PD) equipped with toothed wheels and, floating on the sea, a waterproof case (CE) with integrated rack (C) on it, long enough to slide between the toothed shaft ends of the pumps on the platform (P1).

Description
La présente invention concerne un système marémoteur pour élever un volume donné d'eau douce d'un réservoir situé à un niveau inférieur vers un réservoir installé à une hauteur supérieure, pour créer une chute d'eau suffisante pour faire marcher une centrale hydroélectrique Avantage de ce système par rapport aux systèmes actuels : a) Mouvement perpétuel du même volume d'eau douce. b) Aucun contact de la turbine hydraulique avec l'eau salée, donc, aucune corrosion. D'autre part, la production de l'énergie électrique commence à être limitée par deux facteurs: a) La réduction, à moyen terme, du nucléaire, pour des questions de sécurité. b) L'arrêt des hydrocarbures, due à la pollution, à son effet de serre et à son prix. The present invention relates to a tidal system for raising a given volume of freshwater from a reservoir at a lower level to a tank installed at a higher height, to create a waterfall sufficient to operate an Advantage hydroelectric plant. this system compared to current systems: a) Perpetual movement of the same volume of fresh water. b) No contact of the hydraulic turbine with salt water, therefore, no corrosion. On the other hand, the production of electrical energy begins to be limited by two factors: a) The reduction, in the medium term, of the nuclear, for questions of security. (b) The cessation of hydrocarbons due to pollution, its greenhouse effect and its price.
Il est, donc, urgent, de commencer à chercher à remplacer les moyens actuels par d'autres non polluants et moins dangereux. Si l'on tient compte que 75% de notre planète Terre est constitué d'eau, on doit mettre à noire profit cette énorme source d'énergie. Le principe de fonctionnement de cette invention est fondé sur l'utilisation de la pression, et du dénivellement créés par les marées et par les vagues dans la mer pour acheminer un volume donné d'eau douce d'un réservoir inférieur vers un réservoir supérieur, installé à une hauteur suffisante pour créer une chute d'eau pour faire tourner une turbine dans une centrale hydroélectrique. Ce cycle, renouvelable à chaque marée est, donc, perpétuel. Ce système est composé de deux parties: une partie propulsion installée dans la mer et une partie production qui peut se situer, soit à, terre, soit dans la mer au-dessus de la partie propulsion. Si 20 nécessaire, il peut travailler avec l'eau de mer. Les dessins annexés illustrent l'invention. La figure 1 représente l'ensemble des composants du système : En référence à ce dessin, le système comporte, pour la partie propulsion installée en mer, une plateforme (Pl) soutenue par des supports (Sl) fixés à une base solide (Bl) implantée au fond de 25 la mer. Sur la plateforme (Pl) est montée une centrale de pompage (CP) où sont installées, vis-à-vis, deux pompes à eau (PM) et (PD) avec leurs bouts d'arbre respectifs équipés de roues dentées, un guide crémaillère court (GC), ainsi qu'un guide crémaillère long (GL) soutenu par les supports guide (SG). Dans les supports (SI) de la plateforme (Pl) sont installés des glissières (OL) en longueur, entre 30 lesquelles glissent des guides crémaillère (GC) courts. Sur la mer, glissant entre les supports (Si) de la plateforme (P1) flotte un caisson étanche (CE) avec des ouvertures dans les parties inférieur et supérieur équipées de vannes papillon (VP). Dans le milieu de la partie inférieure de ce caisson étanche (CE) il est fixé un caisson de charge (CC) avec une ouverture dans le côté inférieur équipée d'une vanne libre (VL). Ce caisson sert à alourdir le caisson étanche (CE) lors du retour vers le bas par l'effet du mouvement ondulatoire des vagues, ainsi que lors de la marée descendante. Au milieu de la partie supérieur du caisson étanche (CE) est intégrée une crémaillère (C) suffisamment longue pour atteindre le guide crémaillère long (GL) à l'intérieur de la çentrale de pompage (CP) en période de marée basse, se glissant entre les guides courts (GC) des supports (Si) de la plateforme (Pi) et de l'intérieur de la centrale de pompage (CP). Dans la centrale de pompage (CP), les pompes à eau (PM) et (PD) sont montées vis-à-vis de telle sorte que les roues dentées de leurs bouts d'arbre soient mises en contact, de part et d'autre de la crémaillère intégrée (C). De cette façon, le caisson étanche (CE) avec la crémaillère intégrée (C) et le caisson de charge (CC) font tourner, soit la pompe (PM) lors de la montée des vagues et de la marée montante, soit la pompe (PD) lors de la descente des vagues et de la marée descendante. Le caisson étanche (CE) peut être remplacé par un bateau adapté à là même fin. Pour la partie production, le système comporte une plateforme (P2) soutenue par des supports (S2) fixés à une base solide (B2) ici implantée sur la terre ferme. Sur cette base (B2) est installée 15 un réservoir inférieur (RI) surmonté d'une centrale hydroélectrique (CH). Sur la plateforme (P2) est installé un réservoir supérieur (RS) qui est alimenté en eau par le tuyau de remplissage (TR) relié au côté refoulement des pompes (PM) et (PD) installées dans la centrale de pompage (CP) sur la plateforme (Pl) en mer,'lesquelles s'alimentent en eau, çôté aspiration, par le tuyau d'aspiration (TA) dans le réservoir inférieur (RI) installé sur la base (B2). 20 L'alimentation en eau de la centrale hydroélectrique (CH) est faite par une conduite forcée (CF) équipée d'une vanne papillon (VP), venant du réservoir supérieur (RS), la sortie d'eau de la centrale (CH) se faisant directement dans le réservoir inférieur (RI) sur la base (B2). La figure 2 représente le système en période de marée montante: Le caisson étanche (CE) vide, avec toutes les vannes papillon (VP) fermées, flotte sur la mer, le 25 caisson de charge (CC) en dessous avec sa vanne libre (YL) ouverte, donc, sans charge. Poussé par la marée montante ou par les vagues, le caisson, étanche (CE) monte. La crémaillère intégrée (C) suit le mpuvement vers le haut, faisant tourner dans la centrale de pompage (CP) la pompe (PM) laquelle aspire, par le tuyau (TA), l'eau du réservoir inférieur (RI) sur la base (B2) à terre, pour la refouler, par le tuyau de remplissage (TR), vers le réservoir supérieur (RS) sur la 30 plateforme (P2), l'autre pompe (PD) restant sans action pendant ce temps. La figure 3 représente la mise en service du caisson de charge (CC) qui sert à alourdir le caisson étanche (CE), soit lors des marées descendantes, soit quand, par l'action du mouvement ondulatoire des vagues, la mer redescend. Chaque fois que le caisson étanche (CE) descend, le caisson de charge (CC) ferme sa vanne libre (VL) s'alourdissant par le poids de l'eau à l'intérieur. It is, therefore, urgent to start looking to replace current means with other non-polluting and less dangerous ones. If we take into account that 75% of our planet Earth is made of water, we must put to profit this enormous source of energy. The operating principle of this invention is based on the use of tidal pressure and tidal leveling in the sea to convey a given volume of fresh water from a lower reservoir to an upper reservoir, installed at a height sufficient to create a waterfall to run a turbine in a hydroelectric plant. This cycle, renewable at each tide, is therefore perpetual. This system is composed of two parts: a propulsion part installed in the sea and a production part that can be located either at ground or in the sea above the propulsion part. If necessary, it can work with seawater. The accompanying drawings illustrate the invention. FIG. 1 represents all the system components: With reference to this drawing, the system comprises, for the propulsion portion installed at sea, a platform (P1) supported by supports (S1) fixed to a solid base (B1). located on the bottom of the sea. On the platform (Pl) is mounted a pumping station (CP) where are installed, vis-à-vis, two water pumps (PM) and (PD) with their ends of tree respective geared wheels, a short rack guide (GC), and a long rack guide (GL) supported by the guide brackets (SG). In the supports (SI) of the platform (Pl) are installed slideways (OL) in length, between which slide short rack guides (GC). On the sea, sliding between the supports (Si) of the platform (P1) floats a waterproof case (CE) with openings in the lower and upper parts equipped with butterfly valves (VP). In the middle of the lower part of this waterproof case (CE) there is fixed a load box (CC) with an opening in the lower side equipped with a free valve (VL). This box is used to weigh down the water chamber (CE) during the return down by the effect of wave movement of the waves, as well as during the tide down. In the middle of the upper part of the waterproof case (CE) is integrated a rack (C) long enough to reach the long rack guide (GL) inside the pump center (CP) during low tide, slipping between the short guides (GC) of the supports (Si) of the platform (Pi) and the inside of the pumping station (CP). In the pumping station (CP), the water pumps (PM) and (PD) are mounted so that the toothed wheels of their shaft ends are brought into contact with each other on both sides. other of the integrated rack (C). In this way, the water chamber (CE) with the integrated rack (C) and the load box (CC) rotate either the pump (PM) during the rise of the waves and the rising tide, or the pump ( PD) during the descent of the waves and the ebb tide. The waterproof case (CE) can be replaced by a boat adapted for the same purpose. For the production part, the system comprises a platform (P2) supported by supports (S2) fixed to a solid base (B2) here implanted on the mainland. On this base (B2) is installed a lower tank (RI) surmounted by a hydroelectric power station (CH). On the platform (P2) is installed an upper tank (RS) which is supplied with water by the filling pipe (TR) connected to the discharge side of the pumps (PM) and (PD) installed in the pumping station (CP) on the platform (Pl) at sea, which feeds water, suction side, through the suction pipe (TA) into the lower tank (RI) installed on the base (B2). The water supply of the hydroelectric plant (CH) is made by a forced pipe (CF) equipped with a butterfly valve (VP), coming from the upper tank (RS), the water outlet of the plant (CH). ) occurring directly in the lower tank (RI) on the base (B2). FIG. 2 shows the system during a rising tide: The empty tank (CE), with all closed butterfly valves (VP), floats on the sea, the load box (CC) underneath with its free valve ( YL) open, therefore, without charge. Driven by rising tide or waves, the box, waterproof (CE) rises. The integrated rack (C) moves upwards, rotating the pump (PM) in the pump unit (CP), which draws water from the lower tank (RI) on the base through the pipe (TA). (B2) on the ground, for the discharge, by the filling pipe (TR), to the upper reservoir (RS) on the platform (P2), the other pump (PD) remaining without action during this time. Figure 3 shows the commissioning of the load box (CC) used to weigh down the water chamber (EC), either during tides down, or when, by the action of waves wave movement, the sea back down. Each time the waterproof case (CE) goes down, the load box (CC) closes its free valve (VL), which is weighed down by the weight of the water inside.
Avec cet alourdissement, ainsi qu'avec le poids de la crémaillère intégrée (C), le caisson étanche (CE) descend. La crémaillère intégrée (C) suit le mouvement vers le bas, faisant tourner dans la centrale de pompage (CR) la pompe (PD) laquelle aspire, par le tuyau (TA), l'eau du réservoir inférieur (RI) sur la base (B2) à terre pour la refouler, par le tuyau de remplissage (TR), vers le réservoir supérieur (RS) sur la plateforme (P2), la pompe (PM) restant sans action pendant ce temps. With this weight, as well as with the weight of the integrated rack (C), the waterproof case (CE) goes down. The integrated rack (C) follows the downward movement, rotating the pump (PD) in the pumping station (CR), which draws the water from the lower tank (RI) on the base through the pipe (TA). (B2) on the ground to discharge it, by the filling pipe (TR), to the upper tank (RS) on the platform (P2), the pump (PM) remaining without action during this time.
La figure 4 représente le système au niveau maximum de la marée haute. Figure 4 shows the system at the maximum level of high tide.
Propulsé par la marée, le caisson étanche (CE) avec la crémaillère intégrée (C) et le caisson de charge (CC), montent jusqu'au niveau le plus haut de la marée montante, faisant tourner soit la pompe (PM) soit la pompe (PD) qui vont, ainsi, transférer l'eau du réservoir inférieur (RI) vers le réservoir supérieur (RS). Powered by the tide, the waterproof case (CE) with the integrated rack (C) and the load box (CC), rise to the highest level of the rising tide, rotating either the pump (PM) or the pump (PD) which will thus transfer water from the lower tank (RI) to the upper tank (RS).
La mise en service de la centrale hydroélectrique (CH). The commissioning of the hydroelectric plant (CH).
Lorsque l'eau dans le réservoir supérieur (RS) arrive à un niveau prédéterminé, la vanne papillon (VP) de la conduite forcée (CF) s'ouvre et la centrale hydroélectrique (CH) se met en route, produisant de l'électricité. De même, si l'eau descend à un niveau minimum pré-établi, la vanne papillon (VP) de la conduite forcée (CF) se ferme et la centrale hydroélectrique (CH) s'arrête. La figure 5 représente le système au moment du passage de la marée haute vers la marée basse: Lorsque le caisson étanche (CE) arrive au niveau maximum de la marée haute, les vannes papillon (VP) s'ouvrent laissant l'eau de mer entrer. Quand le caisson étanche (CE) est rempli d'eau, les vannes papillon (W) se ferment, l'alourdissant. La vanne libre (VL) du caisson de charge (CC) se ferme, aussi, augmentant le poids de l'ensemble When the water in the upper reservoir (RS) reaches a predetermined level, the throttle valve (VP) of the penstock (CF) opens and the hydroelectric plant (CH) starts, producing electricity . Likewise, if the water drops to a pre-set minimum level, the throttle valve (VP) of the penstock (CF) closes and the hydroelectric station (CH) stops. Figure 5 shows the system at the time of the passage from high tide to low tide: When the water chamber (CE) reaches the maximum level of high tide, butterfly valves (VP) open leaving sea water enter. When the water chamber (EC) is filled with water, the butterfly valves (W) close, weighing it down. The free valve (VL) of the load box (CC) closes, too, increasing the overall weight
La figure 6 représente le système en période de marée descendante: Figure 6 shows the system during the ebb tide:
Alourdi par l'eau dans son intérieur, par le poids de la crémaillère intégrée (C) ainsi que par le caisson de charge (CC), le caisson étanche (CE) commence à descendre, suivant, avec un certain décalage, la marée descendante. La çrém,aillère (C) suit le mouvement vers le bas, faisant tourner dans la centrale de pompage (CP) la pompe (PD) laquelle aspire, par le tuyau (TA), l'eau du réservoir inférieur (RI) sur la base ($2) à terre pour la refouler, par le tuyau de remplissage (TR), vers le réservoir supérieur (RS) sur la plateforme (P2), la pompe (PM) restant sans action pendant ce temps. Burdened by the water in its interior, by the weight of the integrated rack (C) as well as by the load box (CC), the waterproof case (CE) begins to descend, following, with a certain lag, the ebb tide . The spindle (C) follows the downward movement, causing the pump (PD) to rotate in the pumping station (CP), which draws, through the pipe (TA), the water from the lower reservoir (RI) onto the base ($ 2) on the ground to discharge it, through the filling pipe (TR), to the upper tank (RS) on the platform (P2), the pump (PM) remaining without action during this time.
Durant ce temps, la centrale hydroélectrique (CH) produit de l'énergie électrique modulant sa puissance en fonction du niveau d'eau dans le réservoir supérieur (RS). During this time, the hydropower plant (CH) produces electrical energy modulating its power according to the level of water in the upper reservoir (RS).
La figure 7 représente le système au moment du passage de la marée basse vers la marée haute: Le caisson étanche (CE), arrivant à un niveau pré-établi avant le niveau le plus bas de la marée descendante, s'arrête, ouvrant ses vannes papillon (W) pour vider l'eau de son intérieur. Quand le caisson étanche (CE) est vide, les vannes papillon (VP) se ferment. La vanne libre du caisson de charge (CC) s'ouvre, le dégageant de son poids supplémentaire. La marée, après avoir passée par son niveau le plus bas, remonte, poussant le caisson étanche (CE) avec la crémaillère intégrée (C) vers le haut pour recommencer le cycle avec la marée 5 montante. La figure S/M représente le système avec les parties propulsion et production en mer. Figure 7 shows the system at the time of the passage from low tide to high tide: The watertight caisson (CE), arriving at a pre-established level before the lowest level of the ebb tide, stops, opening its doors. butterfly valves (W) to empty the water from inside. When the water chamber (EC) is empty, the butterfly valves (VP) close. The free valve of the load box (CC) opens, releasing it from its extra weight. The tide, after passing through its lowest level, rises, pushing the water box (CE) with the integrated rack (C) upwards to start the cycle again with the rising tide. Figure S / M shows the system with the parts propulsion and production at sea.
