Abstract
Dispositif hydro-générateur positionné dans un cours d’eau fonctionnant à partir de l’énergie potentielle créé par le dispositif sans avoir besoin de créer un ouvrage spécifique comme une retenue d’eau.Hydro-generator device positioned in a watercourse operating from the potential energy created by the device without the need to create a specific structure such as a water reservoir.
Description
La présente invention concerne un caisson hydro-générateur placé dans un cours d’eau et fonctionnant à partir de l’énergie potentielle créée par le fluide contournant un panneau de ce caisson afin de récupérer de l’énergie.The present invention relates to a hydro-generator box placed in a watercourse and operating from the potential energy created by the fluid bypassing a panel of this box in order to recover energy.
Des hydroliennes fonctionnent à partir de l’énergie cinétique du fluides. Les hydroliennes à allure rapide type à profil d’aile sont performantes et nécessitent des vitesses de cours d’eau suffisantes. Des hydroliennes à allure lente comme par exemple de type Savonius peuvent fonctionner avec des vitesses de fluide faibles.
Les hydroliennes à allure lente possèdent peu de pales et nécessitent d’avoir un grand diamètre pour avoir un couple important.Tidal turbines operate from the kinetic energy of fluids. Fast-acting tidal turbines of the wing profile type are efficient and require sufficient river velocities. Slow-speed hydrokinetic turbines such as the Savonius type, for example, can operate with low fluid velocities.
Slow-speed tidal turbines have few blades and require a large diameter to have a high torque.
Les roues à eau fonctionnent à partir de l’énergie potentielle. Cette énergie potentielle est créée à partir d’une retenue d’eau permettant d’obtenir une différence d’altitude de niveau d’eau.
La retenue d’eau est un ouvrage qu’il faut réaliser, qui modifient la configuration du cours d’eau, qui peut être bénéfique pour freiner l’écoulement d’eau à la mer, qui nécessitent des ouvrages supplémentaires comme par exemple des passes à poissons.Water wheels operate from potential energy. This potential energy is created from a reservoir of water making it possible to obtain a difference in altitude of water level.
The water reservoir is a work that must be carried out, which modifies the configuration of the watercourse, which can be beneficial to slow down the flow of water to the sea, which requires additional works such as for example passes to fish.
Le caisson hydro-générateur ne nécessite pas la réalisation de retenue d’eau. L’énergie potentielle est créée par le caisson. Il suffit de placer le caisson dans le cours d’eau. Le caisson crée vis à vis du cours d’eau une perte de charge qui provoque une très faible surélévation du niveau d’eau en amant de ce caisson.The hydro-generator box does not require the creation of a water reservoir. The potential energy is created by the box. Simply place the box in the stream. The caisson creates, vis-à-vis the watercourse, a head loss which causes a very slight elevation of the water level upstream of this caisson.
La plaque (2) bloquant le fluide, la pression en amont de cette plaque augmente tandis que en arrière (4) de cette plaque , il existe une zone en dépression. Le fluide en contournant la plaque prends une légère augmentation de vitesse et perd de ce fait de la pression.
Le caisson possède un orifice de sortie (3) dont la section légèrement est plus petite que la section d’ouverture (1) du caisson. Cette réduction d’orifice oblige le fluide à de nouveau prendre de la vitesse et perdre de la pression .
La différence de pression due à la surpression existant en amont de la plaque (2) et la dépression existant au niveau de l’arrière de la plaque (2) permets d’entraîner un rotor ou une turbine (5) positionné au niveau de l’orifice (3).
The plate (2) blocking the fluid, the pressure upstream of this plate increases while behind (4) of this plate, there is a depression zone. The fluid bypassing the plate takes a slight increase in speed and thereby loses pressure.
The casing has an outlet port (3) whose section is slightly smaller than the opening section (1) of the casing. This orifice reduction forces the fluid to again pick up speed and lose pressure.
The pressure difference due to the overpressure existing upstream of the plate (2) and the depression existing at the rear of the plate (2) makes it possible to drive a rotor or a turbine (5) positioned at the level of the orifice (3).
Le rotor peut être de différents types. Les turbines à profils d’ailes d’avions ont généralement peu de pales. Elles sont performantes et sont destinées avec des vitesses d’écoulement rapides afin d’avoir une vitesse de rotation importante. Les vitesses d’écoulement des cours d’eau sont généralement faibles et il est préférable d’utiliser une turbine avec beaucoup d’aubes. La vitesse de rotation est faible et le couple est important en raison du grand nombre d’aubes.The rotor can be of different types. Airfoil turbines generally have few blades. They are efficient and are intended with fast flow velocities in order to have a high rotation speed. Stream flow velocities are generally low and it is best to use a turbine with lots of blades. The rotational speed is low and the torque is large due to the large number of blades.
Le rotor (5) peut entraîner par exemple une pompe ou une génératrice électrique. La vitesse de rotation du rotor (5) étant faible, il est nécessaire de prévoir un multiplicateur de vitesse. Le multiplicateur de vitesse et la génératrice électrique peut être positionnés hors de l’eau.The rotor (5) can drive, for example, a pump or an electric generator. The speed of rotation of the rotor (5) being low, it is necessary to provide a speed multiplier. The speed multiplier and the electric generator can be positioned out of the water.
Il est possible de prévoir plusieurs caissons hydro-générateurs dans un cours d’eau. Il est possible de les mettre cote à cote. On peut aussi les superposer. Dans le cas de superposition de caisson, on relie les turbines de chaque caisson par un même arbre. Cet arbre moteur entraînera par exemple une génératrice électrique.It is possible to provide several hydro-generator boxes in a watercourse. It is possible to put them side by side. They can also be superimposed. In the case of box superposition, the turbines of each box are connected by the same shaft. This motor shaft will, for example, drive an electric generator.
Afin de protéger le caisson hydro-générateur des objets pouvant circuler dans le cours d’eau, il peut être mis des barres de protection devant l’ouverture du caisson (1). Il est possible de donner une inclinaison à ces barres de protection pour éviter que les objets circulant dans l’eau soient bloqués au niveau du caisson, il est possible de rajouter une casquette en partie haute de l’ouverture. Cette casquette favorise la surpression. Un grillage peut aussi être mis en place pour éviter que les poissons pénètrent dans le caisson. La mise en place d’un grillage nécessite un nettoyage régulier.In order to protect the hydro-generator box from objects that may circulate in the watercourse, protective bars can be placed in front of the opening of the box (1). It is possible to give an inclination to these protection bars to prevent objects circulating in the water from being blocked at the level of the box, it is possible to add a cap in the upper part of the opening. This cap promotes overpressure. A mesh can also be put in place to prevent fish from entering the box. The installation of a fence requires regular cleaning.
Claims (5)
System characterized by the superposition of several devices according to one of the preceding claims, the boxes are superimposed and all the axes (8) of the rotors (5) are made integral in order to be able to drive, for example, an electric generator assembly (9) (10 )
