Description

[0001] La présente invention concerne la production d'électricité, plus précisément la production d'énergie hydraulique. The present invention relates to the production of electricity, more specifically the production of hydraulic energy.

[0002] Un but de la présente invention est de permettre la production d'électricité sans nuisance de déchets ou de bruit et avec une faible usure du procédé. An object of the present invention is to allow the production of electricity without nuisance waste or noise and with low wear of the process.

[0003] Ce but est atteint par le procédé défini dans la revendication 1 et par le tube souterrain défini dans la revendication 2. This object is achieved by the method defined in claim 1 and by the underground tube defined in claim 2.

[0004] Le schéma technique annexé montre le principe de l'invention. Sur ce schéma, 1 désigne un tube d'eau douce à circuit fermé, 2 désigne une pente d'accélération de ce tube, 3 désigne une remontée avec turbinage de ce tube, 4 désigne un alternateur, 5 désigne un transformateur, 6 désigne le réseau électrique conventionnel, 7 désigne un ascenseur à turbines immergées et 8 désigne des turbines hydrauliques. The attached technical diagram shows the principle of the invention. In this diagram, 1 designates a closed-circuit freshwater tube, 2 designates an acceleration slope of this tube, 3 designates an ascent with turbines of this tube, 4 designates an alternator, 5 designates a transformer, 6 designates the conventional electrical network, 7 designates an elevator with submerged turbines and 8 designates hydraulic turbines.

[0005] Le tube 1 est un tunnel creusé dans la terre sur une profondeur entre 500 et 5000 mètres et comprenant une portion verticale (la remontée d'eau 3). Il est hermétique et rempli d'eau, d'un diamètre et d'une longueur pouvant varier. The tube 1 is a tunnel dug in the ground to a depth between 500 and 5000 meters and comprising a vertical portion (the rising water 3). It is airtight and filled with water, of varying diameter and length.

[0006] Le tube 1 est rempli complètement d'eau, sans poche d'air. [0006] Tube 1 is completely filled with water, with no air pockets.

[0007] Le tube 1 est une boucle fermée, de forme cherchée pour obtenir les meilleures performances. [0007] The tube 1 is a closed loop, of the shape sought to obtain the best performance.

[0008] Le principe est simple : le chaud montant et le froid descendant, l'eau contenue dans le tube 1 en forme de boucle circule continuellement dans le tunnel. The principle is simple: the rising hot and falling cold, the water contained in the tube 1 in the form of a loop circulates continuously in the tunnel.

[0009] Les turbines hydrauliques 8 placées en série dans le tube 1 sont entrainées en rotation dans le chemin de l'eau en mouvement, générateur d'une électricité continuelle. L'ascenseur à turbines immergées 7 permet une facilitation de l'entretien. The hydraulic turbines 8 placed in series in the tube 1 are driven in rotation in the path of the moving water, generator of continuous electricity. The submerged turbine lift 7 facilitates maintenance.

[0010] L'alternateur 4 et le transformateur 5 sont adaptés pour que l'électricité produite puisse être utilisée dans le réseau électrique standard 6, pour une consommation usuelle. The alternator 4 and the transformer 5 are adapted so that the electricity produced can be used in the standard electrical network 6, for usual consumption.

[0011] Une production continuelle d'électricité est incontestablement un grand avantage, sans nuisance de déchets ou de bruit et avec une faible usure du procédé. [0011] A continuous production of electricity is undoubtedly a great advantage, without nuisance of waste or noise and with a low wear of the process.

[0012] Les performances du système inventé dépendent principalement de la forme du tube en boucle fermée, de sa longueur et du diamètre, ainsi que du nombre de turbines 8. [0012] The performance of the invented system depends mainly on the shape of the closed-loop tube, its length and diameter, as well as the number of turbines 8.

[0013] Pour concrétiser cette industrie électrique souterraine, une autorisation juridique d'utilisation du sol est nécessaire, comme pour le processus dit à injection d'eau, actuellement en essai en Suisse, mais estimé plus à risque que la présente invention. [0013] To realize this underground electrical industry, a legal authorization for the use of the soil is necessary, as for the so-called water injection process, currently being tested in Switzerland, but considered to be more at risk than the present invention.

[0014] L'invention présente de nets avantages de sécurité de conception, le tube 1 pouvant faire plusieurs mètres de diamètre, reprenant les techniques éprouvées des tunnels ferroviaires ou routiers suisses. De plus, les turbines 8 peuvent être des turbines utilisées depuis des années sous les barrages hydrauliques alpins suisses. The invention has clear design safety advantages, the tube 1 can be several meters in diameter, using the proven techniques of Swiss rail or road tunnels. In addition, the turbines 8 can be turbines that have been used for years under the Swiss Alpine hydraulic dams.
