The wind turbine (1) has a body (2) associated to a hub (3) for fixing blades (4, 5). The hub is extended radially beyond the body, and comprises blade articulation units for articulating the blades so as to allow movement of the blades between an active position by radial projection with respect to the body and a retracted position for storage of the blades along the body. The hub includes radial branches (6-8) for receiving feet (9, 10) of the blades, and articulation rods for articulating the feet on the hub.

Description

Eolienne La présente invention concerne une éolienne. Plus particulièrement l'invention concerne par exemple les éoliennes de taille réduite pouvant par exemple être embarquées à bord d'un bateau pour fournir de l'électricité au réseau de bord de celui-ci. Les éoliennes de ce type, même si elles sont de taille réduite, sont tout de même relativement encombrantes au vu de l'exiguïté à bord des bateaux. Par ailleurs, il arrive également que dans certaines situations, ces éoliennes ne soient plus utiles et qu'il soit alors souhaitable de pouvoir les démonter pour pouvoir les ranger par exemple. Cependant, ces opérations de démontage puis de remontage sont relativement fastidieuses et l'exiguïté du bord entraîne même un risque de perdre certains composants par dessus bord. De plus, il n'y a pas, en général, beaucoup d'espace disponible à bord pour ranger une telle éolienne même démontée qui présente un encombrement en volume très important. Une éolienne comporte en effet un corps d'éolienne associé à un moyeu sur lequel sont fixées des pales qui s'étendent radialement à partir de ce moyeu et cette éolienne est raccordée au réseau de bord par exemple du bateau par des moyens de connexion électrique. The present invention relates to a wind turbine. More particularly the invention relates for example to smaller wind turbines may for example be shipped on board a boat to provide electricity to the network of the latter. Wind turbines of this type, even if they are small, are still relatively bulky in view of the small size on board the boats. Moreover, it also happens that in certain situations, these wind turbines are no longer useful and it is then desirable to be able to disassemble them to store them for example. However, these disassembly and reassembly operations are relatively tedious and the smallness of the edge even leads to a risk of losing some components overboard. In addition, there is not, in general, a lot of space available on board for storing such wind turbine even disassembled which has a large space requirement. A wind turbine has in fact a wind turbine body associated with a hub on which are fixed blades extending radially from the hub and the wind turbine is connected to the ship's network for example of the boat by means of electrical connection.

On conçoit que lors du démontage et du remontage d'une telle éolienne, il convient, d'une part d'assurer la déconnexion et la reconnexion électriques de l'éolienne au réseau de bord, de même que le démontage et le remontage complets des pales. Or, tout ceci n'est pas facile à faire surtout dans un espace aussi restreint que le pont d'un bateau. Le but de l'invention est donc de résoudre ces problèmes. A cet effet, l'invention a pour objet une éolienne du type comportant un corps d'éolienne associé à un moyeu de fixation de pales, caractérisée en ce que le moyeu s'étend radialement au-delà du corps de l'éolienne et comporte des moyens d'articulation des pales, de manière à permettre leur déplacement entre une position active en saillie radiale par rapport au corps de l'éolienne et une position escamotée de rangement des pales le long du corps de cette éolienne. It is conceivable that during the dismantling and reassembly of such a wind turbine, it is necessary on the one hand to ensure the electrical disconnection and reconnection of the wind turbine to the on-board network, as well as the complete disassembly and reassembly of the wind turbines. blades. However, all this is not easy to do especially in a space as small as the deck of a boat. The object of the invention is therefore to solve these problems. For this purpose, the subject of the invention is a wind turbine of the type comprising a wind turbine body associated with a hub for fixing blades, characterized in that the hub extends radially beyond the body of the wind turbine and comprises articulation means of the blades, so as to allow their displacement between an active position radially projecting relative to the body of the wind turbine and a retracted position of storage of the blades along the body of the wind turbine.

Selon d'autres aspects de l'invention, l'éolienne comprend l'une ou plusieurs des caractéristiques suivantes : - le moyeu comporte des branches radiales de réception de talons des pales et des tiges d'articulation de ces talons sur le moyeu, - elle comporte des moyens de blocage des pales en position active ou escamotée, - les moyens de blocage comportent un bouchon formant nez de l'éolienne de blocage des pales, fixé de manière démontable sur le moyeu, - le bouchon formant nez est fixé sur le moyeu par vissage, - le bouchon formant nez est de type imperdable, - le bouchon formant nez est relié par un lien souple au corps de l'éolienne, et - le corps de l'éolienne comporte un connecteur électrique rapide et étanche. According to other aspects of the invention, the wind turbine comprises one or more of the following characteristics: the hub comprises radial heel-receiving branches of the blades and articulation rods of these heels on the hub; it comprises means for blocking the blades in the active or retracted position, - the locking means comprise a stopper forming the nose of the wind turbine blocking the blades, removably fixed on the hub, - the nose plug is fixed on the hub by screwing, - the nose cap is captive type, - the nose plug is connected by a flexible link to the body of the wind turbine, and - the body of the wind turbine has a quick and waterproof electrical connector.

L'invention sera mieux comprise à l'aide de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels : les figures 1 et 2 représentent des vues en perspective éclatée de devant et de derrière d'une éolienne selon l'invention ; et la figure 3 représente une vue de dessus de cette éolienne. On a en effet illustré sur ces figures, une éolienne qui est désignée par la référence générale 1 sur ces figures et qui comporte un corps d'éolienne désigné par la référence générale 2. The invention will be better understood with the aid of the description which follows, given solely by way of example and with reference to the appended drawings, in which: FIGS. 1 and 2 show exploded perspective views of the front and behind a wind turbine according to the invention; and Figure 3 shows a top view of this wind turbine. In fact, these figures show a wind turbine which is designated by the general reference 1 in these figures and which comprises a wind turbine body designated by the general reference 2.

Ce corps d'éolienne est associé à un moyeu désigné par la référence générale 3 qui porte des pales telles que par exemple des pales désignées par les références 4 et 5 sur ces figures. En fait et comme cela est illustré sur ces figures, le moyeu 3 comporte par exemple des branches qui s'étendent radialement au-delà du corps de l'éolienne et qui comportent des moyens d'articulation des pales, de manière à permettre leur déplacement entre une position active en saillie radiale par rapport au corps de l'éolienne et une position escamotée de rangement des pales le long du corps de cette éolienne. This wind turbine body is associated with a hub designated by the general reference 3 which carries blades such as for example blades designated by references 4 and 5 in these figures. In fact and as illustrated in these figures, the hub 3 comprises for example branches which extend radially beyond the body of the wind turbine and which comprise means of articulation of the blades, so as to allow their displacement. between an active position projecting radially from the body of the wind turbine and a retracted position of storage of the blades along the body of this wind turbine.

Les branches du moyeu 3 comportent alors par exemple des empreintes de réception de talons de fixation des pales et sont associées à des tiges d'articulation de ceux-ci sur ce moyeu pour permettre à un utilisateur de les déplacer entre leurs deux positions et assurer un maintien rigide dans l'une ou l'autre de ces deux positions. Sur la figure 1 on peut en effet constater que le moyeu 3 comporte trois branches radiales désignées par les références générales 6, 7 et 8 de réception de talons tels que par exemple les talons 9 et 10 des pales 4 et 5. L'extrémité de chaque branche du moyeu 3 est alors munie par exemple d'une tige d'articulation du talon correspondant d'une pale sur ce moyeu pour permettre un déplacement des pales entre leur position active en saillie radiale par rapport au corps de l'éolienne, comme cela est illustré pour la pale 4 et une position escamotée de rangement de la pale le long du corps de l'éolienne, comme cela est illustré pour la pale 5. The branches of the hub 3 then comprise, for example, blade-fixing heel-receiving impressions and are associated with articulation rods thereof on this hub to allow a user to move them between their two positions and to ensure rigid hold in one or the other of these two positions. In FIG. 1, it can be seen that the hub 3 has three radial branches designated by the general references 6, 7 and 8 for receiving heels, such as, for example, the heels 9 and 10 of the blades 4 and 5. The end of each branch of the hub 3 is then provided for example with a hinge pin of the corresponding heel of a blade on this hub to allow movement of the blades between their active position radially projecting relative to the body of the wind turbine, as this is illustrated for the blade 4 and a retracted position of storage of the blade along the body of the wind turbine, as illustrated for the blade 5.

Dans l'exemple illustré, les moyens d'articulation sont formés par une simple tige d'articulation portée par le moyeu et traversant un trou du talon de la pale. Cependant, d'autres modes de réalisation encore peuvent être envisagés. Par ailleurs, il est également prévu des moyens de blocage des pales en position active ou escamotée. Ces moyens de blocage se présentent par exemple sous la forme d'un bouchon formant nez de l'éolienne désigné par la référence générale 11 et fixé d'une manière démontable comme par exemple par vissage, sur le moyeu 3, pour assurer un blocage des pales dans l'une ou l'autre des positions. Une vis non représentée peut en effet être utilisée en association avec un trou taraudé du moyeu pour fixer ce nez sur ce moyeu de façon démontable. Ce bouchon est de type imperdable et est relié par exemple par un lien souple de type classique (non représenté) au corps de l'éolienne Ce bouchon formant nez est également muni d'un manchon de guidage et de centrage désigné par la référence générale 12 sur la figure 2 et épousant la forme du moyeu 3. On conçoit alors qu'une telle structure présente un certain nombre d'avantages, notamment au niveau du démontage, du remontage et du rangement de l'éolienne et en particulier des pales de celle-ci, ce qui permet par exemple de ranger cette éolienne dans un sac afin de la stocker dans un endroit de dimension réduite lorsque l'on n'en a pas besoin. A cet effet, le corps de l'éolienne peut alors être muni d'un connecteur 5 électrique rapide et étanche pour faciliter également la connexion et la déconnexion électriques au réseau de bord. Bien entendu, d'autres modes de réalisation encore peuvent être envisagés comme par exemple le rangement dans un coffre intégré au pont du bateau In the illustrated example, the hinge means are formed by a simple hinge pin carried by the hub and passing through a hole in the heel of the blade. However, other embodiments can be envisaged. Furthermore, it is also provided means for locking the blades in the active or retracted position. These locking means are for example in the form of a nose plug of the wind turbine designated by the general reference 11 and fixed in a removable manner such as for example by screwing, on the hub 3, to ensure a locking of blades in one or the other position. A not shown screw can indeed be used in combination with a tapped hole of the hub to fix the nose on the hub removably. This plug is of the captive type and is connected for example by a conventional type of flexible link (not shown) to the body of the wind turbine. This nose plug is also provided with a guiding and centering sleeve designated by the general reference 12. in Figure 2 and following the shape of the hub 3. It is understood that such a structure has a number of advantages, particularly in terms of disassembly, reassembly and storage of the wind turbine and in particular the blades of the This allows, for example, storing this wind turbine in a bag in order to store it in a place of reduced size when it is not needed. For this purpose, the body of the wind turbine can then be provided with a fast and waterproof electrical connector 5 to facilitate also the electrical connection and disconnection to the on-board network. Of course, other embodiments can be envisaged such as for example the storage in a trunk built into the deck of the boat
