Description

La présente invention concerne la réalisation d'un ensemble indus triel destiné à produire de ltélectricité à partir de l'énergie du vent.
(fig 1) (39)
Cet sur un support flottant/situé à proximité d'un rivage et, fixé, par 1'intermédiaire d'un dispositif d'ancrage/tr%l- culé en sous face, à un portique immergé (1) articulé à ses deux extrémités.The present invention relates to the production of an industrial unit intended to produce electricity from wind energy.
(fig 1) (39)
This on a floating support / located near a shore and, fixed, by means of an anchoring device / tr% l- culated on the underside, to a submerged gantry (1) articulated at its two ends .

Le dispositif d'ancrage est réalisé dans une cloche d'air. Il permet la rotation du support flottant commandée par l'action du vent ainsi que les mouvements d'oscillation provoqués par la houle, par rapport à un axe horizontal indifférent. The anchoring device is made in an air bell. It allows the rotation of the floating support controlled by the action of the wind as well as the oscillating movements caused by the swell, relative to an indifferent horizontal axis.

Le transport du courant électrique s'effectue au travers de cette cloche d'air, jusqu'à la zône d'utilisation, par l'intermédiaire d'une conduite flexible étanche (2). The electric current is transported through this air bell, to the area of use, via a sealed flexible pipe (2).

Cet ensemble désigné " Centrale Aéramotrice Flottante " comprend les caractéristiques suivantes :
1) Forme aérodynamique ( Fig 1)
La forme représentée sur la figure 1 est conçue de façon à faciliter la rotation de la centrale jusqu'à sa position de fonctionnement. Le profil ds la partie avant abritant les génératrices (3) permet un écoulement dynamique de l'action du vent.This set, designated "Floating Air Plant", includes the following characteristics:
1) Aerodynamic shape (Fig 1)
The shape shown in Figure 1 is designed to facilitate rotation of the unit to its operating position. The profile in the front part housing the generators (3) allows dynamic flow of the wind action.

2) Ensemble éolien ( Fig 1,2,3,4 )
Il se compose d'un nombre pair de roues à pales verticales supportées par des portiques (4) comportant chacun, à l'exception du portique central, un arbre de transmission vertical (5).2) Wind assembly (Fig 1,2,3,4)
It consists of an even number of wheels with vertical blades supported by gantries (4) each comprising, with the exception of the central gantry, a vertical drive shaft (5).

Chaque roue est équipée d'un système d'obturation à deux volets à débat- tement circulaire. Le volet bas (6) s'ouvre en s'escamotant dans le carénage inférieur, le volet haut (7) s'ouvre par débattement vers
La manoeuvre d'ouverture du volet bas s'effectue par gravité. La manoeuvre de fermeture du volet bas, celles d'ouverture et de fermeture du volet haut s'effectuent en utilisant l'énergie absorbée par les roues au moyen d'un dispositif d'embrayage.Each wheel is fitted with a two-fold shutter system with circular motion. The bottom flap (6) opens by retracting into the lower fairing, the top flap (7) opens by movement towards
The opening operation of the bottom flap is carried out by gravity. The closing shutter maneuver, those for opening and closing the top shutter are carried out using the energy absorbed by the wheels by means of a clutch device.

Le débattement des roues, au niveau inférieur, s'effectue dans un
carénage conçu de façon à permettre la fixation des portiques d'éolienne,
en laissant le passage aux arbres de transmission horizontaux (8) reliés aux génératrices.The wheel travel at the lower level takes place in a
fairing designed to allow the attachment of gantry wind turbines,
leaving the passage to the horizontal transmission shafts (8) connected to the generators.

Le passage (9) situé sous le portique central est prévu pour permettre
l'accès au disbositif d'ancrage du support flottant. The passage (9) located under the central portico is designed to allow
access to the floating support anchoring device.

3) Dispositif d'ancras du support flottant ( Fig 5,6,7,8 )
Ce dispositif a pour ralle de permettre les oscillations et la rotation de la centrale tout en reprenant les réactions horizontales et verticales provoquées par l'action du vent.3) Anchor device of the floating support (Fig 5,6,7,8)
The purpose of this device is to allow the oscillations and rotation of the power station while taking up the horizontal and vertical reactions caused by the action of the wind.

Il se compose d'un ensemble de deux couronnes fonctionnant l'une dans l'autre. Une première couronne dite "extérieurs" (10) est solidaire du support flottant par l'intermédiaire de butées horizontales (11) comprenant galets de roulement et ressorts d'application. Une seconde couronne dite "intérieure" (12) est solidaire du portique immergé et articulé sur celui-ci. It consists of a set of two crowns operating one inside the other. A first so-called "external" ring (10) is secured to the floating support by means of horizontal stops (11) comprising rollers and application springs. A second crown called "interior" (12) is integral with the submerged gantry and articulated on it.

Les oscillations sont obtenues au moyen d'un dispositif de roulement (13) situé dans les secteurs avant et arrière de la couronne extérieure et agissant suivant un axe circulaire situé dans son plan. La zflne d'évolution de ce dispositif est un plan sphérique. Il transmet les réactions horizontales. The oscillations are obtained by means of a rolling device (13) located in the front and rear sectors of the outer ring and acting along a circular axis located in its plane. The area of evolution of this device is a spherical plane. It transmits horizontal reactions.

La. rotation est obtenue au moyen d'un dispositif de roulement sur trois faces (14) agissant en contact avec la couronne intérieure et prévu également dans les secteurs avant et arrière de la couronne extérieure. The rotation is obtained by means of a rolling device on three faces (14) acting in contact with the inner ring and also provided in the front and rear sectors of the outer ring.

Ce dispositif transmet les réactions horizontales et verticales.This device transmits horizontal and vertical reactions.

Les réactions horizontales sont reprises par une ossature de raidissage du plan sphérique situé dans le secteur opposé au sens de l'action du vent. The horizontal reactions are taken up by a stiffening framework of the spherical plane located in the sector opposite to the direction of the action of the wind.

Les réactions verticales sont transmises à un plancher oscillant(15) intégré dans la structure du support flottant, par l'intermédiaire de bracons (16) articulés à leurs extrémités. Les articulations des bracons sont du type à axe vertical avec appuis à rotule. The vertical reactions are transmitted to an oscillating floor (15) integrated into the structure of the floating support, by means of struts (16) articulated at their ends. The articulations of the bracons are of the vertical axis type with ball bearings.

4) Plancher oscillant ( Fig-5,7,8 )
Ce plancher a pour rôle de transmettre les réactions verticales à la structure du support flottant tout en absorbant les oscillations.4) Swinging floor (Fig-5,7,8)
The role of this floor is to transmit vertical reactions to the structure of the floating support while absorbing the oscillations.

Oans la zane considérée, cette structure est schématisée par un ensemble rigide comprenant un plancher haut (17) et un plancher bas (18) liés, l'un à l'autre, par quatre poteaux (19), l'ensemble étant solidaire d'un système de poutres métalliques (20) assurant la répartition des efforts sur le support flottant. In the zane considered, this structure is shown diagrammatically by a rigid assembly comprising a high floor (17) and a low floor (18) linked, one to the other, by four posts (19), the assembly being integral with 'a system of metal beams (20) ensuring the distribution of forces on the floating support.

Pour permettre les oscillations, on intercale entre le plancher oscillant et les planchers haut et bas de la structure, deux ensembles de vérins (21) à circuit hydraulique. Chaque ensemble de vérins est alimenté par une centrale commune leur permettant d'agir suivant le principe des vases communicants. Ils agissent, alternativement en "poussant", suivant le sens de la réaction verticale du portique immergé. Toutefois, ils sont prévus "à double effet" afin de palier à la défaillance èventtiel le de l'un des deux ensembles de vérins. To allow oscillations, between the oscillating floor and the upper and lower floors of the structure, two sets of jacks (21) with hydraulic circuit are inserted. Each set of cylinders is supplied by a common central unit allowing them to act on the principle of communicating vessels. They act, alternately by "pushing", according to the direction of the vertical reaction of the submerged gantry. However, they are provided "double acting" in order to overcome the eventual failure of one of the two sets of cylinders.

La stabilité horizontale du plancher oscillant est assurée par une articulation en son centre réalisée sur un axe coulissant dans deux supports rigides (22) fixés, l'un en sous face du plancher haut, l'autre au dessus du plancher bas de la structure. The horizontal stability of the oscillating floor is ensured by an articulation in its center carried out on a sliding axis in two rigid supports (22) fixed, one below the high floor, the other above the low floor of the structure.

La stabilité anti rotation du plancher oscillant est assurée par des butées à galets avec ressort d'application (23) prenant appui sur les poteaux du plancher
Après chaque oscillation, le retour à une position horizontale du plancher oscillant est sollicité par quatre vérins de rappel (24) permettant, en outre, de compenser les charges différentielles transmises par les bracons.The anti-rotation stability of the oscillating floor is ensured by roller stops with application spring (23) resting on the floor posts
After each oscillation, the return to a horizontal position of the oscillating floor is requested by four return cylinders (24) also making it possible to compensate for the differential loads transmitted by the struts.

Le support rigide fixé sur le plancher bas abrite une boite de con nection/s2s5rant le raccordement des canalisations électriques (26) provenant des génératrices. The rigid support fixed to the low floor houses a connection box / s2s5rant for the connection of the electrical pipes (26) coming from the generators.

5) portique immergé ( Fig 1,2,4 !
Ce portique est conçu de façon à reprendre les efforts transmis par l'action du vent quelle que soit sa direction. Sa fixation au dispositif d'ancrage du support flottant se situe dans la zône émargée et est obtenue par encastrement sur un élément de portique (27) préalablement monté sur la couronne intérieure.5) submerged gantry (Fig 1,2,4!
This gantry is designed to take up the forces transmitted by the action of the wind regardless of its direction. Its attachment to the floating support anchoring device is located in the signed area and is obtained by embedding on a gantry element (27) previously mounted on the inner ring.

L'ancre articule des deux pieds du portique est fix a un axe scellé dans une masse de béton (28! suffisante pour reprendre les efforts horizontaux et verticaux. The anchor articulated on both legs of the gantry is fixed to an axis sealed in a mass of concrete (28! Sufficient to take up the horizontal and vertical forces.

Le tronçon vertical (29) situé au point d'encastrement des deux jambes du portique comporte une gaine (30) assurant le raccordement à la canalisation électrique installée dans la conduite flexible; ta) liaison électrique entre ce tronçon et le support flottant est établie par un contacteur extensible (31) mobile autour d'un axe vertical. The vertical section (29) located at the point of embedding the two legs of the gantry comprises a sheath (30) ensuring the connection to the electrical pipe installed in the flexible pipe; ta) electrical connection between this section and the floating support is established by an extendable contactor (31) movable about a vertical axis.

6) Installations complémentaires ( Fig 1,5,5,7,8 )
Elles ont pour but d'assurer une autonomie de fonctionnement.6) Additional installations (Fig 1,5,5,7,8)
They are intended to ensure operating autonomy.

Il est prévu notamment : - Salle de contrôle (325 - Atelier d'entretien avec monorail de dépannage et ouverture d'accès au droit de chaque éolienne (33) - magasin de stoc kage des pièces de rechange (34) - Sas d'accès aux vérins (35) - Sas d'ace ces à l'ancrage articulé (36) - Logement de personnel (37).  It is planned in particular: - Control room (325 - Maintenance workshop with troubleshooting monorail and access opening to the right of each wind turbine (33) - storage room for spare parts (34) - Access lock cylinders (35) - Airlock these hinged anchor (36) - Staff accommodation (37).
