Abstract

The power plant has a turbine (2) connected to a current producing alternator and placed between two hollow floating caissons (1). The caissons permit to immerse a lower part of the turbine, serve as a ballast (11) to refine the immersion and are connected by two longitudinal aprons (6). The turbine has blades (7) of helical shape. The plant is maintained in a waterway by two vertical beams (10) fixed to bed (4) of the waterway.

Description

Cette invention concerne une centrale hydro-électrique installée sur desThis invention relates to a hydroelectric power plant installed on

caissons flottants.Ces caissons s'adaptant automatiquement au niveau de l'eau assurent à la turbine(2) productrice de courant un rendement régulier et continuel  Floating caissons.These boxes adapting automatically to the water level ensure the turbine (2) producing current a regular and continuous performance

que ce soit en période de crue ou d'étiage.  whether during flood or low water periods.

Elle est constituée par une très grosse' turbine(2) de 4 à 5 métres de diamétre et de 6 à 10 nétres de longueur. Afin que cette turbine soit la plus silencieuse possible, ses pales ont une forme légèrement hélicoïdale.De ce fait, ?0 celles-çi attaquent la surface de l'eau en biais,c'est donc le chant des pales qui se présente en premier à la surface de l'eau et non le plat de la pale.4insi ces pales(7)en pénétrant dans l'eau hélicoidalement et progressivement coupent l'eau au lieu de la fouetter d'où un fonctionnement plus silencieux.  It consists of a very large turbine (2) 4 to 5 meters in diameter and 6 to 10 inches in length. In order for this turbine to be as quiet as possible, its blades have a slightly helical shape. Because of this, when they attack the surface of the water at an angle, it is therefore the singing of the blades that comes first. on the surface of the water and not the flat of the blade. Thus these blades (7) penetrating the water helicoidally and gradually cut the water instead of whipping it for a quieter operation.

Cette turbine est placée entre deux caissons flottants(i) creux et fait corps' avec ceux çi.Ces caissons flottants permettent l'immersion de la partie inférieure de la turbine et servent de ballast(.i1)pour affiner cette immersion.  This turbine is placed between two floating caissons (i) hollow and is part 'with those ci.Ces floating caissons allow the immersion of the lower part of the turbine and serve as ballast (.i1) to refine this immersion.

Ces caissons sont reliés entre eux par deux tabliers longitudinaux(6)qui assurent la riidité de l'ensemble.  These boxes are interconnected by two longitudinal aprons (6) which ensure the riidity of the whole.

Cet ensemble est maintenu aux deux extrémités, dans le courant d'eau,par deux poutrelles(i0)verticales en acier solidement fixées au fond du cours d'eau(4).Ces poutrelles assurent la stabilité de la centrale et empêchent tous déplacements que peuvent occasionner les fortes tempêtes et les vents violents.Ces poutrelles sont jumelées de manière à former,entre elles,une glissière(3).Ces glissières sont prévues pour recevoir des guides coulissants(8)sur lesquels viennent se fixer les axes de la turbine.En se déplaçant verticalement, ces guides permettent à l'ensemble, caissons et turbine,de monter ou descendre suivant le niveau de lteau(5).Les pales(7) immergées de cette turbine reçoivent alors,de la part du courant,une force colossale et sans à coups.  This assembly is maintained at both ends, in the stream of water, by two vertical steel beams (i0) firmly fixed to the bottom of the watercourse (4) .These beams ensure the stability of the plant and prevent any movement that can cause severe storms and strong winds.These beams are twinned so as to form, between them, a slide (3) .These slides are provided to receive sliding guides (8) on which are fixed the axes of the turbine By moving vertically, these guides allow the assembly, caissons and turbine, to rise or fall depending on the water level (5). The blades (7) immersed of this turbine then receive, from the current, a colossal force and without blows.

Cette force est transt.lise à l'alternateur(9) producteur de courant électrique.  This force is transferred to the alternator (9) producing electricity.

Cette centrale hydro-électrique réunit les avantages suivants: - Puissance colossale -Force constante et régulière sans à-coups - Multiplication possible rapproché sur le même cours d'eau -Silencieuse - Discréte(à ras l'eaù) -Crues sans effet Etiage sans effet -Entretien pratiquement nul -Non polluante -Ne réchauffe pas l'eau du cours d'eau et elle est sans nuisance apparente.  This hydroelectric power plant has the following advantages: - Colossal power - Constant and regular force without jerks - Possible multiplication possible on the same watercourse - Silent - Discrete (flush with the water) - Cranes without effect Etiage without effect -Maintenance virtually nil -Not polluting -Do not heat water in the watercourse and it is without apparent nuisance.

Cette invention peut avoir l'application industrielle suivante:Installation sur tous cours d'eau ayant un courant puissant et constant.  This invention may have the following industrial application: Installation on any watercourse having a strong and constant current.

Ainsi,cette centrale hydro-électrique,çue ce soit en période de crues ou.de.basses eaux en s'adaptant au niveau des eaux, quelqu' il soit, se_ roque des ir:tenpéries et reste toujours en activité.  Thus, this hydro-electric power station, whether it is during periods of high or low water, adapting itself to the level of the water, whatever it may be, roams in the air and remains in activity.

Cette invention évite et supprime les problê::es des éoliennes qui souvent tournent de misère et produisent du courant électrique seule-lent quand vent il y a, et pas du tout...quand elles ne tournent pas.  This invention avoids and eliminates the problems of wind turbines that often run out of wretchedness and produce single-slow electricity when there is wind, and not at all ... when they do not run.

Dès lors,pour rester dans ce créneau spécial de production.le courant électrique, il ne serait pas du tout illogique d'appeler cette invention tout simplement.... 30 "Hydrolienne".  Therefore, to stay in this special niche of electric power production, it would not be at all illogical to call this invention simply .... "Hydrolian".
