Abstract

The device has two arms (10) each with two wheels (3) at its ends and the two arms are linked by two looped cables (4) on which the parachutes (1,6) are mounted. One parachute opens out and is displaced by the wind while the other closes up. Alternatively the parachutes may be rigid and permanently open with the return part of the cycle protected from the wind by a casing. To catch the wind, the device is mounted on a pylon (8) and a shell (7) with a vane (10) to direct it into the wind. To capture the force of the waves, the arms are replaced by a system of floats.

Description

La présente invention concerne un dispositif qui produit de l'énergie électrique à partir d'un système de va-et-vient de parachutes. The present invention relates to a device which produces electrical energy from a back-and-forth system of parachutes.

L'énergie éolienne n'est jusqu'à présent utilisée qu'a partir de traditionnels appareils nommé 'éoliennes' , de même que les énergies marines ne sont jusqu'à présent utilisées que sous formes d'installations appelées 'centrales houlomotrices'
Pas plus que les éoliennes, les houlogenerateurs ne peuvent être implantés n'importe ou. Pour l'instant ces systèmes n'exploitent pas la force de l'eau et du vent au maximum.Wind energy has so far been used only from traditional devices called 'wind turbines', just as marine energy has so far been used only in the form of installations called 'wave power plants'
No more than wind turbines, wave generators cannot be installed anywhere. For the moment these systems do not exploit the force of water and wind to the maximum.

Le dispositif selon l'invention permet de remédier a ces inconvénients. Il comporte en effet deux bras parallèle.The device according to the invention overcomes these drawbacks. It indeed has two parallel arms.

Chaque bras possède un plateau a chaque extrémité, ils sont reliés par un câble tendu.Each arm has a tray at each end, they are connected by a stretched cable.

Les deux câbles sont entraînes par les parachutes soigneusement fixés aux deux câbles comme le montre la figure n0 . The two cables are driven by the parachutes carefully attached to the two cables as shown in Figure n0.

Ces parachutes sont gonflés, ils entraînent alors les deux câbles qui a leur tour entraînent les quatre plateaux. Ils sont alors en rotation, le plateau inférieur en rotation lui aussi transmet, grâce a une courroie dentée, sa vitesse de rotation aux générateurs haute-tension qui devront produire de l'énergie électrique.These parachutes are inflated, they then drive the two cables which in turn drive the four trays. They are then in rotation, the lower plate in rotation also transmits, thanks to a toothed belt, its speed of rotation to the high-voltage generators which will have to produce electrical energy.

Ce dispositif peut fonctionner à partir de la force du vent, en effet quant le vent frappe les parachutes, il les gonfle et déclenche ainsi tout le système. Pour cela le dispositif est fixé sur une tour. Le dispositif peut également fonctionner à partir de la force des vagues ou du courant de l'eau d'une rivière. Il sera alors fixé sur un système de flotteurs. This device can operate from the force of the wind, in fact when the wind hits the parachutes, it inflates them and thus triggers the whole system. For this the device is fixed on a tower. The device can also operate from the force of waves or the flow of water from a river. It will then be fixed on a system of floats.

Selon des modes particuliers de réalisation - La distance entre les deux plateaux d'un même extrémité dépend de la taille des parachutes. According to particular embodiments - The distance between the two plates of the same end depends on the size of the parachutes.

- Les parachutes peuvent être rigides ou semi-rigides.- The parachutes can be rigid or semi-rigid.

- Les câbles peuvent être remplacés par des chaînes à maillons pour éviter tout glissement du
système. Les plateaux seront alors dentés de façon à recevoir les chaînes.- The cables can be replaced by link chains to prevent slipping of the
system. The plates will then be toothed so as to receive the chains.

- La dimension des deux bras (soit pour une utilisation du type éolienne ou marine )
dépendra du nombre de parachutes.- The dimension of the two arms (either for a wind or marine type use)
will depend on the number of parachutes.

- Les plateaux ont des caractéristiques telle que la figure n"3 pour faciliter le passage des
barres de fixation des parachutes.- The trays have characteristics such as figure n "3 to facilitate the passage of
parachute fixing bars.

En référence à ces dessins, le dispositif comporte deux bras (10), qui comportent chacun un plateau (3), à chaque extrémité, monté sur un axe (11). Un câble (4) relie les deux plateaux d'un même bras (de même pour le second bras). Entre ces deux câbles, évoluent des parachutes (1 et 6) fixés à ces derniers à l'aide de barres (2) et d'un système de fixation (12), une barre de guidage (15 et 17) permet de guider les parachutes lors du fonctionnement.Figure n: l: front view

With reference to these drawings, the device comprises two arms (10), which each comprise a plate (3), at each end, mounted on an axis (11). A cable (4) connects the two plates of the same arm (likewise for the second arm). Between these two cables, there are parachutes (1 and 6) fixed to the latter by means of bars (2) and a fixing system (12), a guide bar (15 and 17) makes it possible to guide the parachutes during operation.

Ces parachutes se déplacent dans le sens du vent. ( parachute ouvert (1), parachute fermé (6) ).Les plateaux alors en mouvement rotatif transmettent leur vitesse à un plateau inférieur (16) qui le transmet à son tour aux générateurs au moyen d'une courroie dentée.These parachutes move in the direction of the wind. (open parachute (1), closed parachute (6)). The plates then in rotary movement transmit their speed to a lower plate (16) which in turn transmits it to the generators by means of a toothed belt.

Ce dispositif est construit sur une tour composée de trois éléments : la coque (7), le pilier (8) et un dispositif (9) qui facilite la rotation du système. Un aileron (10), qui compose une partie du bras, permettra d'orienter le système dans le sens du vent. This device is built on a tower made up of three elements: the shell (7), the pillar (8) and a device (9) which facilitates the rotation of the system. A fin (10), which forms part of the arm, will orient the system in the direction of the wind.

Selon une variante non illustrée, ce dispositif peut être construit sur le toit d'une maison.According to a variant not illustrated, this device can be built on the roof of a house.

Les bras (10) sont remplacés par un système de flotteurs (fig.5) pour le dispositif concernant la production d'énergie électrique à partir de la force des vagues.The arms (10) are replaced by a system of floats (fig. 5) for the device relating to the production of electrical energy from the force of the waves.

Selon une variante non illustrée, les parachutes peuvent être rigides (ouvert en permanence), il faut alors prévoir un boîtier pour recouvrir toute la surface inférieure du bras, pour le dispositif qui fonctionne à partir de la force du vent pour celui qui fonctionne à partir de la force des vagues ou du courant d'eau, le boîtier est placé sur toute la surface supérieure du dispositif. According to a variant not illustrated, the parachutes can be rigid (permanently open), it is then necessary to provide a housing to cover the entire lower surface of the arm, for the device which operates on the strength of the wind for the one which operates on due to the force of the waves or the current of water, the housing is placed over the entire upper surface of the device.

Le dispositif selon l'invention est particulièrement destiné à produire davantage d'énergie électrique renouvelable.  The device according to the invention is particularly intended for producing more renewable electrical energy.
