Abstract

The aerogenerator has a hydraulic actuating cylinder or a pneumatic cylinder, a set of circular plates with slots, and blades with double walls. A set of floors is arranged along a vertical axis of the aerogenerator. A set of stages of the aerogenerator is allowed to slide with each other. A jack allows the set of stages to be folded up when speed of the wind increases. A computer program is provided for deployment of the hydraulic actuating cylinder or pneumatic cylinder, where the program is provided to an anemometer.

Description

-1- Cette innovation permet le déploiement et le repli partiel et total d'un aérogénérateur à axe vertical en fonction de la puissance 'des vents et de l'énergie réclamée. Traditionnellement les aérogénérateurs à axes verticaux ne se replient pas totalement et verticalement, ils ont une hauteur définie lors de leur fabrication ce qui ne leur permet pas de gérer leur vitesse de rotation. Cette innovation est constituée en son centre, à la verticale, d'un vérin hydraulique ou pneumatique à plusieurs paliers qui permet de déployer et de replier simultanément et totalement tous les étages de cet aérogénérateur (image 1).This innovation allows the partial and total deployment and retreat of a vertical axis wind turbine according to the power of the winds and the energy required. Traditionally vertical axis wind turbines do not fold completely and vertically, they have a defined height during their manufacture which does not allow them to manage their rotational speed. This innovation consists in its center, vertically, a hydraulic or pneumatic cylinder with several levels that allows to deploy and fold simultaneously and completely all floors of this wind turbine (picture 1).

Cet aérogénérateur est constitué de multiples étages dont chacun est en un seul bloc constitué comme suit : (image 2). Un plateau circulaire sur sa partie supérieure et plusieurs pales à double parois verticales et en demi-cercle ouvertes à leurs extrémités hautes et basses afin de laisser coulisser les pales des étages supérieurs elles-mêmes à double parois verticales.This aerogenerator consists of multiple stages, each of which is in a single block constituted as follows: (image 2). A circular plate on its upper part and several double-walled vertical and semi-circular blades open at their upper and lower ends to let slide the blades of the upper floors themselves double vertical walls.

Tous les plateaux circulaires supérieurs de chaque étages sauf le dernier, ont le nombre et les fentes nécessaires au repli des pales des étages supérieurs dans les étages inférieurs (image 4). Seul les pales du dernier étage sont à simple paroi et son plateau supérieur circulaire est coiffé d'un dôme en forme de demi-lentille (images 3et 6).All the upper circular trays of each stage except the last, have the number and the slots necessary for the folding of the blades of the higher floors in the lower floors (picture 4). Only the blades of the last stage are single-walled and its circular upper plate is capped with a dome in the shape of a half-lens (images 3 and 6).

Chaque étage (plateau et pales) tourne librement sur lui-même au moyen d'un roulement à billes fixé au centre du plateau circulaire, le roulement à billes étant lui-même fixé sur la partie supérieure du palier du vérin central (en bleu images 1,4et 6) . Le nombre de paliers du vérin central est identique au nombre d'étages de cet aérogénérateur( image 1).Each stage (plate and blades) turns freely on itself by means of a ball bearing fixed in the center of the circular plate, the ball bearing being itself fixed on the upper part of the bearing of the central cylinder (in blue images 1,4 and 6). The number of bearings of the central cylinder is identical to the number of stages of this aerogenerator (image 1).

Le déploiement maximum de chaque étage ne doit pas excéder 99% afin de contribuer à l'effet d'engrenage de haut en bas de cet aérogénérateur. La partie inférieure de cet aérogénérateur (le socle circulaire de transmission de l'énergie) est constituée d'un plateau dépourvu de pales mais avec le nombre et les fentes nécessaires au repli complet de tous les étages supérieurs ainsi que d'un arbre de transmission creux venant coiffer la base du vérin central sur lequel il tourne librement au moyen de deux roulement à billes:le premier roulement sur sa partie supérieure, le second roulement à la base de l'arbre de transmission, ces deux roulements sont eux-mêmes fixer sur la base du vérin central (image 1 et 5). -2- Le déploiement du vérin hydraulique ou pneumatique de cet aérogénérateur est géré par un programme informatique spécifique couplé à un anémomètre mesurant la vitesse des vents. Cet aérogénérateur est principalement destiné aux usages suivant: Terrestre : production d'énergies - se repli dans un silo de faible profondeur- maintenance à hauteur d'homme dans le silo. Offshore: production d'énergie électrique - plusieurs aérogénérateurs « en chandelier »: un seul mat et plusieurs branches. Embarqué: sur le pont supérieur de certains navires de commerces, de croisières afin de contribuer à leurs productions d'énergie électrique. Comme système de propulsion principal de multicoques de loisirs ou de compétitions pour lesquels il faudra tenir compte de l'effet « vent/vitesse »généré par leur propre déplacement.The maximum deployment of each stage must not exceed 99% in order to contribute to the gearing effect from top to bottom of this aerogenerator. The lower part of this aerogenerator (the circular power transmission base) consists of a plate without blades but with the number and the slots necessary for the complete retreat of all the upper stages as well as a transmission shaft. hollow capping the base of the central cylinder on which it rotates freely by means of two ball bearings: the first bearing on its upper part, the second bearing at the base of the transmission shaft, these two bearings are themselves fix on the base of the central cylinder (image 1 and 5). -2- The deployment of the hydraulic or pneumatic cylinder of this wind turbine is managed by a specific computer program coupled to an anemometer measuring the wind speed. This aerogenerator is mainly intended for the following uses: Terrestrial: energy production - falls back into a silo of shallow depth - maintenance at man's height in the silo. Offshore: production of electrical energy - several wind turbines "in candlestick": only one mast and several branches. Embarked: on the upper deck of some commercial ships, cruises to contribute to their production of electrical energy. As the main propulsion system for recreational multihulls or competitions for which the "wind / speed" effect generated by their own displacement must be taken into account.
