Abstract

The turbine has vertical blades (5) suspended to a crest of a fixed tower (1), where shape of the turbine is cone shape. A cap (2) is turned with a support on a post (3), and the blades are integrated to a bridle (4). Upper part of the blades is articulated in the cap, and lower part of the blades is articulated in a rotor plate (6). The bridle is integrated to the plate by a truncated cone (7) that is made of stainless steel. An opening and closing unit opens ad closes the blades to stabilize the turbine based on force of wind.

Description

La présente invention concerne une éolienne à axe vertical pour la transformation de l'énergie du vent en énergie électrique ou mécanique. Ce qui existe à ce jour : Éolienne horizontale, gigantesque, dénaturante, d'un coût d'installation et de maintenance très élevé en raison de sa conception. Éolienne verticale d'un coût d'installation plus modeste mais avec l'inconvénient d'une importante perte de charge du fait de la friction de son roulement de pied qui maintient l'équilibre de l'ensemble. The present invention relates to a vertical axis wind turbine for converting wind energy into electrical or mechanical energy. What exists to date: Horizontal wind turbine, gigantic, denaturing, very expensive installation and maintenance due to its design. Vertical wind turbine with a lower installation cost but with the disadvantage of a significant loss of load because of the friction of its foot roll which maintains the balance of the whole.

Le but de l'invention est de remédier à ces inconvénients en proposant une éolienne verticale pendue de puissance électrique intermédiaire, plus esthétique et moins bruyante. Cette éolienne de forme conique à pales verticales est suspendue au sommet d'un mât fixe (1). Celle-ci comporte une calotte (2) tournant avec appui sur un pivot (3), constituant le sommet du mât (1). The object of the invention is to overcome these disadvantages by proposing a vertical wind turbine suspended from intermediate electrical power, more aesthetic and less noisy. This conical wind turbine with vertical blades is suspended at the top of a fixed mast (1). This comprises a cap (2) rotating with support on a pivot (3) constituting the top of the mast (1).

Pour la calotte (2), la coiffe intérieure peut être construite en matériau de haute dureté, céramique ou diamant artificiel ; le pivot (3) peut être conçu dans les mêmes matériaux. Cette éolienne est essentiellement constituée de deux parties. Une partie fixe et une partie mobile dite rotor. For the cap (2), the inner cap may be constructed of high hardness material, ceramic or artificial diamond; the pivot (3) can be designed in the same materials. This wind turbine is essentially made up of two parts. A fixed part and a mobile part called rotor.

L'ensemble de la partie mobile est constituée de la calotte (2) de forme conique et d'une bride circulaire (4) en acier usiné, le tout assemblé par un filetage à pas fins sur la calotte (2) La base de la bride (4) reçoit en son épaisseur des axes bagués (11), une pluralité de pales verticales (5) et en son diamètre intérieur, soudé, un cône tronqué (7) en tôle d'inox lui- même soudé à sa base sur un plateau (6) qui reçoit l'articulation de l'axe des pales (5) constituant le rotor de l'éolienne. Concernant les pales (5) en partie haute, l'axe est centré et bagué (11) pour l'orientation de chaque pale (5) sur la bride (4) ; en partie basse, l'axe est centré et bagué (11) pour l'orientation de chaque pale (5) sur le plateau (6) ; en son milieu chaque pale (5) reçoit un palier de renfort (10) fixé sur le cône (7). On notera que les pales (5) sont uniformément réparties autour de l'axe, c'est-à-dire autour du mât (1). Les pales (5), de forme concave sur la longueur, sont soudées sur un axe qui est maintenu en haut et en bas par des bagues (11). Traversant le plateau (6), l'axe des pales (5) reçoit un pignon conique (13) pour l'articulation . The entire moving part consists of the cap (2) conical and a circular flange (4) of machined steel, all assembled by a fine pitch thread on the cap (2) The base of the flange (4) receives in its thickness ringed pins (11), a plurality of vertical blades (5) and welded inside diameter, a truncated cone (7) of stainless steel sheet itself welded to its base on a plate (6) which receives the articulation of the axis of the blades (5) constituting the rotor of the wind turbine. Concerning the blades (5) in the upper part, the axis is centered and ringed (11) for the orientation of each blade (5) on the flange (4); in the lower part, the axis is centered and ringed (11) for the orientation of each blade (5) on the plate (6); in the middle each blade (5) receives a reinforcement bearing (10) fixed on the cone (7). Note that the blades (5) are uniformly distributed around the axis, that is to say around the mast (1). The blades (5), of concave shape along the length, are welded on an axis which is held up and down by rings (11). Crossing the plate (6), the axis of the blades (5) receives a conical pinion (13) for the articulation.

L'ensemble d'ouverture et de fermeture des pales (5) se fait par une roue dentée (14) et des pignons coniques (13), le tout actionné par un vérin électrique (non représenté sur la figure),asservi à la vitesse du vent pour stabiliser l'éolienne. Ce plateau rotor (6) disposant d'une trappe de visite pour la maintenance du mécanisme intérieur à la base du plateau (non représenté sur la figure) est centré sur la base du mât (1) par un roulement conique (non représenté sur la figure), lui-même maintenu par un palier circulaire (17) boulonné au plateau rotor (6). Ce palier circulaire (17) usiné en acier porte, en partie haute, un frein à disque (8) pour l'arrêt complet de l'ensemble des pales, un tachymètre (9) et en dessous deux flasques en cuivre (20) servant à la transmission de l'électricité par deux balais pour l'asservissement du vérin électrique ; ce palier comporte en partie basse un moyeu annelé pour l'entraînement de la boite de vitesse hydraulique (15) disposant d'un blocage en rotation en cas d'anomalies, A l'intérieur de cône (7), sont fixés au mât (1), des systèmes : de dégivrage (12), de stabilisation (18) (gyroscope) et une surveillance vidéo (19) orientable pour le contrôle des mécanismes intérieurs En sa base, sous le plateau rotor (6), s'articule un ensemble composé d'une boite de vitesse 15 et d'un alternateur (non représenté sur la figure) coiffant le mât et constituant l'élément de production d'électricité de l'éolienne. Pour la partie fixe de l'éolienne, le mât de sustentation (1) est en profil d'acier 5 (HEA) ; pour la partie tournante, celui-ci est ancré à sa base dans un massif de béton armé (16). On notera que la forme particulière du mât (1) permet le passage de la câblerie notamment. The opening and closing assembly of the blades (5) is done by a toothed wheel (14) and bevel gears (13), all actuated by an electric jack (not shown in the figure), slaved to the speed wind to stabilize the wind turbine. This rotor plate (6) having a inspection hatch for the maintenance of the internal mechanism at the base of the plate (not shown in the figure) is centered on the base of the mast (1) by a tapered bearing (not shown in FIG. figure), itself held by a circular bearing (17) bolted to the rotor plate (6). This circular machined steel bearing (17) carries, at the top, a disc brake (8) for the complete arrest of all the blades, a tachometer (9) and underneath two copper flanges (20) serving the transmission of electricity by two brushes for servocontrol of the electric cylinder; this bearing comprises in the lower part a corrugated hub for driving the hydraulic gearbox (15) having a rotational locking in case of anomalies, Inside cone (7), are fixed to the mast ( 1), systems: defrost (12), stabilization (18) (gyroscope) and a video surveillance (19) orientable for the control of the internal mechanisms In its base, under the rotor plate (6), articulates a set composed of a gearbox 15 and an alternator (not shown in the figure) covering the mast and constituting the power generation element of the wind turbine. For the fixed part of the wind turbine, the lift mast (1) is made of steel profile 5 (HEA); for the rotating part, it is anchored at its base in a reinforced concrete block (16). Note that the particular shape of the mast (1) allows the passage of the cable including.
