Description
Invention destinée à produire de l'électricité en des endroits deInvention intended to produce electricity in places of
montagne non desservis par des circuits de distribution. mountain not served by distribution channels.
Positionnée dans une veine d'eau rendue rapide par la pente du Positioned in a vein of water made rapid by the slope of the
site, sans modification du contexte existant. site, without modification of the existing context.
s Positionnement assuré par quatre câbles ou chaînes non tributaires des rives ou berges, placés en amont du générateur dans la veine d'eau, immobilisés par quatre pieux en métal enfoncés profondément. A l'arrière de cet engin, deux câbles fixés au centre de cinq io pans, formant gouvernails, tendent l'ensemble pour le maintenir en position. Autonome de toutes constructions maçonnées, sans nuisance pour la flore et la faune, ne produisant aucun déchet, ni bruit désagréable. Utilisant la force de l'eau en mouvement rapide pour actionner un alternateur par l'intermédiaire de sept couronnes de pales placées s Positioning ensured by four cables or chains not dependent on the banks or banks, placed upstream of the generator in the water stream, immobilized by four metal piles driven deep. At the rear of this machine, two cables fixed to the center of five sections, forming rudders, stretch the assembly to hold it in position. Autonomous of all masonry constructions, without nuisance for flora and fauna, producing no waste or unpleasant noise. Using the force of fast-moving water to activate an alternator through seven crowns of blades placed
face à l'arrivée de l'eau.facing the arrival of water.
Caractérisée par le fait qu'elle est constituée d'un châssis porteur à claire voie, à cinq pans, monobloc en tube d'acier inoxydable, soudés à l'arc, dont la partie face à l'arrivée de l'eau, en forme d'entonnoir porte les quatre fixations aux câbles ou chaînes de postionnement. L'espace entre les cinq tubes du châssis est occupé par un alternateur inversé, du fait que son induit est fixe, solidaire des cinq pans gouvernails, et que, ce qui est habituellement le stator, est tournant. Au centre des cinq pans gouvernails, dans le cône terminal, fixe, de l'alternateur, est placé un groupe de diodes, visitable, convertissant l'électricité alternative produite par l'alternateur, en courant continu, d'o part un câble acheminant cette production vers des accumulateurs de stockage, pour ensuite, être utilisée en usage domestique. Le nombre de pales des sept couronnes, placées autour de l'alternateur, face à l'arrivée de l'eau, est dégressif, pour utiliser au Characterized by the fact that it consists of a clear, five-sided, monobloc chassis made of stainless steel tube, arc welded, the part facing the arrival of water, in funnel-shaped carries the four attachments to cables or positioning chains. The space between the five tubes of the chassis is occupied by an inverted alternator, because its armature is fixed, integral with the five rudder panels, and that, which is usually the stator, is rotating. In the center of the five rudders, in the terminal, fixed cone of the alternator, is placed a group of diodes, which can be visited, converting the alternating electricity produced by the alternator into direct current, from where a cable routing this production to storage accumulators, to then be used for domestic use. The number of blades of the seven crowns, placed around the alternator, facing the water inlet, is decreasing, to use at
maximum la force de l'eau, sans trop ralentir le flux liquide. maximum water strength, without slowing down the liquid flow too much.
Ce nombre étant successivement, de dix pales, neuf, huit, sept, This number being successively, of ten blades, nine, eight, seven,
six, cinq et quatre.six, five and four.
Chaque couronne possède à l'extrémité des pales, un cercle formant déflecteur, orientant le flux liquide vers le centre des pales de la couronne suivante, réduisant relativement l'effet de Each crown has a deflector circle at the end of the blades, directing the liquid flow towards the center of the blades of the next crown, relatively reducing the effect of
centrifugation de l'eau.centrifugation of water.
La partie antérieure du déflecteur capte une partie du flux The front part of the deflector captures part of the flow
liquide passant à proximité de ce cercle. liquid passing near this circle.
Dans le cône avant de l'alternateur servant de fixation au châssis porteur, est placé un roulement à billes et un joint d'étanchéité, ainsi qu'à l'arrière entre la partie tournante et le cône fixe. Lors de la visite de maintenance conseillée par le fabriquant, toutes les pièces agissantes sont démontables, y compris les couronnes de pales qui, étant positionnées à une place précise, sont In the front cone of the alternator used for fixing to the support frame, a ball bearing and a seal are placed, as well as at the rear between the rotating part and the fixed cone. During the maintenance visit recommended by the manufacturer, all the active parts are removable, including the blades crowns which, being positioned in a precise place, are
immobilisées par quatre vis painteau. immobilized by four paint screws.
Une des particularité importante de cette invention est qu'il est An important feature of this invention is that it is
recherché la visibilité aisée de toutes les pièces la composant. sought the easy visibility of all the parts composing it.
L'alternateur est protégé par deux demi-coques étanches The alternator is protected by two watertight half-shells
composées de matière plastique rigide armée de fibre de verre. composed of rigid plastic reinforced with fiberglass.
Toutes les parties étanches sont munies de gorges destinées à contenir des joints de matière molle et de gomme siliconée, qui All the waterproof parts are provided with grooves intended to contain seals of soft material and silicone gum, which
seront écrasés, relativement,par la boulonnerie de serrage. will be crushed, relatively, by the tightening bolts.
Un système de chèvre à palan permet, lors de la visite de maintenance, d'extraire ce générateur de la veine d'eau. Ce système A hoist goat system allows, during the maintenance visit, to extract this generator from the water stream. This system
est important dans les lieux o l'on craint le gel. is important in places where there is a risk of frost.
