Abstract

The invention relates to a floating hydraulic station, operating with water current, collecting the potential energy of a mass of water flowing towards the sea in order to transform it into moving power. It consists of a chute fitted with an inlet gulley which is adjustable in depth and comprises at the opposite end a discharge pipe inclined downwards through which a considerable active force escapes, in the form of a liquid stream propelled with a certain speed, which hits the blades of a non-sunk turbine providing moving power. Floats having a controlled immersion depth and fitted with ballast containers enclosing small inflatable reservoirs, support the station assembly in a position which is suitable for operation. The floating hydraulic station which is the subject of the invention is in particular intended for pumping water for the irrigation of land to be fertilised.

Description

Station hydraulique flottante fournissant une force motrice
La présente invention a pour objet une station hydraulique flottante fonctionnant au fil de l'eau dont le rôle est de transformer l'énergie poten telle d'une masse d'eau stécoulant vers la mer en force vive utilisable sur l'orgar moteur dwun récepteur hydraulique pour fournir une force motrice
La realisation d'une usine hydraulique sur un cours d'eau dépend essentiel liement: de la configuration géographique, elle nécessite une étude géologique minutieuse alors que la construction proprement dite mobilise un matériel important et exige des crédits considérables.Floating hydraulic station providing a driving force
The present invention relates to a floating hydraulic station operating over water, the role of which is to transform poten energy such as a mass of water flowing towards the sea into a live force usable on the receiver orgar engine dwun hydraulic to provide a driving force
The realization of a hydraulic factory on a watercourse depends essentially liement: of the geographical configuration, it requires a meticulous geological study whereas the construction itself mobilizes an important material and requires considerable credits.

Selon l'invention il est possible, tout en produisant une force motrice notable, de palier à ces inconvénients majeurs en utilisant une ou plusieurs stations hydrauliques flottantes installées en chapelet le long d'un cours d'eau d'un débit moyen sans terrassement et sans fondation.Préfabriquée en atelier par éléments interchangeables,facilement transportables, l'assemblage rapide d'une telle station peut s'effectuer par une main d'oeuvre non spécialisée à proximité du lieu d'exploitation avant son lancement et son ancrage sur la surface d'un cours d'eau, l'ancrage pouvant être similaire à celui utilisé en batellerie. According to the invention it is possible, while producing a significant driving force, to overcome these major drawbacks by using one or more floating hydraulic stations installed in strings along a watercourse of an average flow rate without earthworks and without foundation. Prefabricated in the workshop by interchangeable elements, easily transportable, the rapid assembly of such a station can be carried out by unskilled labor near the place of operation before it is launched and anchored on the surface. of a watercourse, the anchoring can be similar to that used in inland waterways.

Ceci étant donné à titre d'exemple, la construction de cette station flottante peut entre métallique mais aussi en tout autre matériau résistant, elle est constituée d'éléments reliés entre eux par boulonnage ou par un autre pro cédé connu permettant de les rendre amovibles.L'ensemble ensemblese compose tout d'abord d'une trémie horizontale maintenue de chaque côté par des flotteurs spéciaux, puis par une partie active qui comprend un système de refoulement et une turbine0
La trémie d'une certaine longueur,pouvant être de forme pyramidale,est équipée à l'extrémité de sa grande ouverture d'un avaloir béant de mème forme articulable en verticalité par une charnière, pour en orienter le bord d'attaque face au courant au-dessus ou au-dessous du niveau de celui-ci, un système de bloquage de la charnière l'immobilisant à l'altitude désirée, une grille de protection verticale coulissante et amovible se situe devant cet avaloir, à leur base ses barreaux sont pliés vers l'extérieur pour former une denture semblable à celle d'un rateau facilitant la remontée éventuelle des corps étrangers,charriés par le courants qui pourraient se fixer sur cette paroi à claire-voie; à l'autre extrémité conver gente la trémie se termine par un court tuyau de rejet recourbé vers le bas dont l'orifice de sortie est muni dune buse interchangeable débouchant en face du point bas d'une turbine dont l'altitude est modifiable par le système classique de réglage de son support. This being given by way of example, the construction of this floating station can be made of metal but also of any other resistant material, it is made up of elements connected together by bolting or by another known process allowing them to be made removable. The assembly assembly consists first of all of a horizontal hopper maintained on each side by special floats, then by an active part which includes a delivery system and a turbine0
The hopper of a certain length, which can be of pyramidal shape, is equipped at the end of its large opening with a yawning dump of the same shape articulated vertically by a hinge, to orient the leading edge facing the current. above or below the level thereof, a hinge locking system immobilizing it at the desired altitude, a sliding and removable vertical protective grid is located in front of this drain, at their base its bars are folded outwards to form a toothing similar to that of a rake facilitating the eventual ascent of foreign bodies, carried by the currents which could be fixed on this skeleton wall; at the other converging end, the hopper ends in a short downwardly curved rejection pipe, the outlet of which is fitted with an interchangeable nozzle opening opposite the low point of a turbine, the altitude of which can be modified by classic support adjustment system.

Les flotteurs longitudinaux sont fixés parallèllement sur chaque flanc de la trémie par boulonnage pour devenir ainsi solidaires de celle-ci,chacun d'eux constitue un ensemble tubulaire fuselé, rigide non étanche,compartimen té par des cloisons croisillonnées fixées sur la paroi intérieure perpendiculairement à l'axe pour accroître la résistance et pour maintenir en place des ballonnets gonflables en matière élastique munis d'un indicateur de pression et d'une valve de gonflage dont l'orifice d'accès se situe sur le dessus du flotteur, le compartiment d'extrémité avai est étanche, il renferme un ballonnet mais constitue un balast inondable par une soupape d'admission d'eau commandée à distance se situant à la base, l'évacuation du lest s'effectuant par refoulement par un orifice supérieur lors du gonflage du ballonnet.Pour faciliter le déplacement terrestre de la station, des roues amovibles pbur leur récupération se situent sous les flotteurs, elles pivotent autour d'un axe vertical également amovible qui traverse le flotteur de bas en haut en coulissant dans un tube solidaire da sa paroi. The longitudinal floats are fixed parallel to each side of the hopper by bolting so as to become integral with the latter, each of them constitutes a tapered tubular assembly, rigid non-watertight, compartmentalized by crossed partitions fixed on the inner wall perpendicular to the axis to increase the resistance and to hold in place inflatable balloons made of elastic material provided with a pressure indicator and an inflation valve whose access orifice is located on the top of the float, the compartment d end avai is waterproof, it contains a balloon but constitutes a floodable ballast by a remotely controlled water intake valve located at the base, the evacuation of the ballast being effected by discharge through an upper orifice during inflation To facilitate the ground movement of the station, removable wheels for their recovery are located under the floats, they rotate around a vertical axis é also removable which crosses the float from bottom to top by sliding in a tube integral with its wall.

La mise en ordre de marche de cette station flottante consiste tout d'abord à gonfler tous les ballonnets que renferment les flotteurs, à maintenir l'avaloir en position relevée puis à la lancer sur la surface d'un cours d'eau d'un certain débit pour ensuite l'immobiliser par son ancrage, les points d'amarrage se situant sur les flotteurs vers l'amont.La trémie et ses accessoires sont alors suspendus entre les flotteurs au-dessus de la surface de lteau.Pour le fonctionnement il s'agit d'orienter le bord d'attaque de l'avaloir en profondeur pour capter aussittt une certaine masse d'eau qui s'engouffre dans la trémie en produisant, au passage sur sa paroi inférieure oblique, une poussée horizontale et verticale provoquant le cabrage de l'ensemble, la partie amont s'enfonce, la trémie se remplit partiellement alors que le tuyau de rejet et la turbine situés à l'autre extrémité se soulèvent, l'axe longitudinal de-la trémie a dévié en hauteur vers l'aval; l'abaissement de la partie active de la station s'obtient par le remplissage des balasts d'extrémité aval des flotteurs avec de liteau aprés la -restriction du volume de gaz des ballonnets qu'ils renferment, il constitue la première phase du réglage de fonctionnement, par cette intervention le tuyau de rejet est descendu progressivement jusqu'à l'écoulement de la veine liquide par son orifice de sortie, précédemment à cet instant, sous l'effet de la poussée normale du courant, la trémie s'est remplie complètement d'eau, le niveau atteint dans cette partie intérieure retrécie qui émerge, est supérieur à celui de mont; la precsion convergente a augmenté pour devenir concentrique précipi tant les filets d'eau dans le canal de rejet oû s'est contractée la veine liquide débouchant alors de la buse de sortie, animée d'une force vive notable docte sa vitesse et suractivée par la pesanteur avant sa projection contre les aubes, au point bas de la circonférence de la turbine tangentielle, non noyée. Putting this floating station into working order consists first of all in inflating all the balloons contained in the floats, in maintaining the gully in the raised position then in launching it on the surface of a watercourse of a certain flow rate and then immobilize it by its anchoring, the mooring points being located on the floats upstream. The hopper and its accessories are then suspended between the floats above the surface of the water. it is a question of orienting the leading edge of the gully in depth to immediately capture a certain mass of water which rushes into the hopper by producing, on the passage on its oblique lower wall, a horizontal and vertical thrust causing the nose-up of the assembly, the upstream part sinks, the hopper partially fills while the rejection pipe and the turbine located at the other end are raised, the longitudinal axis of the hopper has deviated in height towards downstream; the lowering of the active part of the station is obtained by filling the downstream end ballasts of the floats with batten after the -restriction of the gas volume of the balloons they contain, it constitutes the first phase of the regulation of operation, by this intervention the rejection pipe is lowered progressively until the flow of the liquid stream through its outlet orifice, previously at this time, under the effect of the normal thrust of the current, the hopper is filled full of water, the level reached in this shrunken inner part which emerges is higher than that of mount; the converging precsion increased to become concentric precipitate as the water streams in the rejection channel where contracted the liquid vein then emerging from the exit nozzle, animated by a notable lively force docte its speed and overactivated by the gravity before its projection against the blades, at the low point of the circumference of the tangential turbine, not flooded.

La seconde phase de réglage consiste à modifier l'altitude de la turbine et à rechercher la position définitive favorable au remplissage complet des aubes conditionnant le meilleur rendement de l'appareil moteur. The second phase of adjustment consists in modifying the altitude of the turbine and in seeking the final position favorable to the complete filling of the blades conditioning the best performance of the motor device.

L'utilisation de la puissance motrice disponible fournie par la turbine se fait par l'entraînement d'une machine réceptrice fixée sur la station, si cette machine est Installée sur la terre ferme on utilise alors une transmission classique à distance munie de cardans ou d'un dispositif similaire. The use of the available motive power provided by the turbine is done by the drive of a receiving machine fixed on the station, if this machine is installed on dry land we use a conventional remote transmission equipped with cardan or 'a similar device.

Selon une variante, à la sortie du tuyau de rejet la turbine peut-être substituée par le dispositif connu d'un bélier hydraulique pour l'élévation de l'eau. Alternatively, at the outlet of the rejection pipe the turbine may be replaced by the known device of a hydraulic ram for raising the water.

La station hydraulique flottante objet de la présente invention peut actionner par sa force motrice diverses machines, mais son utilisation est particulièrement destinée au pompage de lteau pour l'irrigation de terres à fertiliser.  The floating hydraulic station which is the subject of the present invention can actuate various machines by its driving force, but its use is particularly intended for pumping water for the irrigation of land to be fertilized.
