Abstract

The wind energy collector consists of modules (16) each with pairs of turbines (1) having spiral or flat blades and located inside Venturi ducts (2). The modules can be set in columns and rows, with the turbines connected to alternators (3) to generate electricity. Each alternator can be geared to several turbines.

Description


va) Eoliennes à grandes surfaces.
b)La présente invention concerne l'énergie éolienne que l'on capte à
partir de turbines doubles de grand format.
va) Large area wind turbines.
b) The present invention relates to wind energy which is captured at
from large format double turbines.

Le dispositif permet de capter de l'énergie éolienne avec le maximum de rendement.Les dispositifs existants utilisent des forces transversales au vent pour faire tourner dea pales ,alors que les éoliennes à grandes surfaces sont telles que le vent agit perpendiculairement aux pales qui s'ouvrent comme des portes battantes.Ainsi la force du vent est directement perpendiculaire aux pales , évitant ainsi toutes par par composition des forces où seules les transversales agissent
Les turbines (1) sont à pales spirales ou planes et sont précédées en amont par un rétrécissement du passage du vent appelé venturi(2).The device makes it possible to capture wind energy with the maximum efficiency. Existing devices use forces transverse to the wind to turn the blades, while the wind turbines with large surfaces are such that the wind acts perpendicular to the blades which are open like hinged doors. Thus the force of the wind is directly perpendicular to the blades, thus avoiding all by composition of the forces where only the transverse ones act
The turbines (1) are spiral or flat blades and are preceded upstream by a narrowing of the wind passage called venturi (2).

Chaque turbine (1) est munie de roulements à aiguilles ou à billes prolo tégés des poussières et du sables par les carterS(9).Each turbine (1) is fitted with needle or ball bearings protected from dust and sand by the casings (9).

Sur le bâtis (10) l'ensemble peut tourner pour mettre les turbines au vent maximum.Les fixations(11) permettent une charpente pour fixer l'éolienne au sol ou sur le bâtis.On the frame (10) the assembly can turn to put the turbines in the maximum wind. The fixings (11) allow a frame to fix the wind turbine to the ground or on the frame.

Un module (16) est composé de deux turbines (1), d'un venturi (2) et d'un éperon (8).Les modules sont séparés ou regroupés.A module (16) is composed of two turbines (1), a venturi (2) and a spur (8). The modules are separated or grouped.

Pour obtenir de l'énergie en suffisance et éviter les difficultés de résistance de matériaux il est bon de mettre plusieurs modules afin de réduire la grandeur des turbines(l;.Une bonne façon de faire est de les mettre en colonne.To obtain sufficient energy and avoid the difficulties of resistance of materials it is good to put several modules in order to reduce the size of the turbines (l;. A good way to do this is to put them in a column.

A l'arrière (aval) des turbines in éperon (8) le long des turbines rend la pression nulle à la sortie du module.At the rear (downstream) of the spur turbines (8) along the turbines makes the pressure zero at the outlet of the module.

Les turbines en mouvement inverse l'une de lauze pour un module fait fonctionner des alternateurs(3) que l'on peut synchroniser pour avoir du courant électrique au secteur (5).The turbines in reverse movement one of lauze for a module operates alternators (3) which can be synchronized to have electric current to the sector (5).

Le courant peut être redressé et passé dans des cuves électrolytIques (4) pour former de l'hydrogène et de l'oxygène que l'on stocke dans les citernes sous pression (6) et (7).The current can be rectified and passed through electrolytic cells (4) to form hydrogen and oxygen which are stored in the pressure tanks (6) and (7).

Ainsi quand le vent souffle1 les alternateurs peuvent fournir du courant électrique dans le réseau EDF directement zSon exédent peut être stoc ké en hydrogène et oxygène pour fournir de l'électricité à partir d'une centrale thermique,quand le vent a baissé.So when the wind is blowing1 the alternators can supply electric current to the EDF network directly. Its excess can be stored in hydrogen and oxygen to supply electricity from a thermal power station, when the wind has dropped.

Le dispositif permet de stocké l'énergie au lieu de mettre la centrale à la terre pendant la diminution de la consomation.The device allows energy to be stored instead of grounding the power plant during the reduction in consumption.

Les pales des turbines sont légères:soit en métal ,soit en fibre de verre et résine renforcéeypar des renforts perpendiculaires à l'axe, renforts (13) ,soit en toile sur chassi.The blades of the turbines are light: either in metal, or in fiberglass and reinforced resin by reinforcements perpendicular to the axis, reinforcements (13), or in canvas on canvas.

Les axes (12) des turbines sont coaxiaux sur des modules portés par une même verticale.Les énergies des modules s'ajoutent.The axes (12) of the turbines are coaxial on modules carried by the same vertical. The energies of the modules are added.

L'éperon (8) permet d'écrire : P= 1/2 D V2 - 0 - Et où Et est l'énergie de turbulance non utilisable.The spur (8) makes it possible to write: P = 1/2 D V2 - 0 - And where Et is the unusable turbulance energy.

Lorsque le vent souffle sur un module de surface amont S ,sa vitesse double au contact des demies turbines de surface S' tel que:
S/S' = V/V' et P = 1/2.4 x V x D où D=mV
En plaçant un nombre n de modules nous obtenons une éolienne à grande surface qui ressemble à un bâtiment de logement ou on aurait omis de mettre les façades. n modules de puissance P chacun donnent une puissance nP.When the wind blows on an upstream surface module S, its speed doubles in contact with the half surface turbines S 'such that:
S / S '= V / V' and P = 1 / 2.4 x V x D where D = mV
By placing a number n of modules we get a large surface wind turbine that looks like a housing building where we would have omitted to put the facades. n power modules P each give a power nP.

Les différents axes (12) peuvent être couplés par pignons(15) de façon à n'avoir besoin que d'un alternateur(3) pour une éolienne ou diminuer le nombre d'alternateurs.The different axes (12) can be coupled by pinions (15) so as to only need an alternator (3) for a wind turbine or reduce the number of alternators.

La charpente est fixée sur les carters (14) de façon à ce que les turbines tournent librement au vent ( Fig. IV). The frame is fixed on the casings (14) so that the turbines turn freely in the wind (Fig. IV).

L'application du dispositif est évidemment de produire de l'électricité ou de l'hydrogène et de l'oxygène que l'on stocke par grand vent pour les moments où le vent n'est pas suffisant.The application of the device is obviously to produce electricity or hydrogen and oxygen which are stored in high winds for times when the wind is not enough.

Un meme dispositif peut être utilisé pour capter l'énergie des courantS marins ou des cours d'eau. The same device can be used to capture the energy of sea currents or watercourses.
