Title

(EN) AN ENERGY CONVERSION SYSTEM WITH AN ELECTRIC MACHINE FOR MULTIPLE PURPOSES

(FR) SYSTÈME DE CONVERSION D'ÉNERGIE DOTÉ D'UNE MACHINE ÉLECTRIQUE À DES FINS MULTIPLES

Abstract

(EN) An Energy Conversion System with an Electric Machine for Multiple Purposes This invention relates to a single machine system shared for wind energy harnessing, water potential energy harnessing and gravity storage. Two common turbines, each of which has multiple circular layers of discrete blades or buckets and is installed on a common shaft and at either side of the machine, are developed for harnessing wind and water energy simultaneously. On each side of the machine, wind and water are fed from separate channels into a common direction-change tube. The common shaft is coupled with that of the machine through pairs of gearboxes to increase angular speed for running the machine more effectively. The water falls from high terrain to low terrain to gain speed while the wind is accelerated by using funnel shaped accelerator in wind tower to reach tens of metres per second for effective energy conversion. A lifting mechanism is installed in the system to fulfill the potential energy storage of concrete or other heavy blocks when there is neither wind nor water. The system could be modified for 1) harnessing wind energy only but can operate as a motor to drive mechanical loads when there is no wind; 2) harnessing water and wind energy at river or lakes' side without gravity storage.

(FR) La présente invention concerne un système de conversion d'énergie doté d'une machine électrique à des fins multiples. L'invention concerne un système de machine unique partagé à la fois pour l'exploitation de l'énergie éolienne, l'exploitation de l'énergie potentielle hydraulique et le stockage gravitaire. Deux turbines communes, dont chacune comporte de multiples couches circulaires de pales discrètes ou de godets et est installée sur un arbre commun et de chaque côté de la machine, sont développées pour exploiter simultanément l'énergie du vent et de l'eau. De chaque côté de la machine, le vent et l'eau sont introduits à partir de canaux séparés dans un tube à changement de direction commun. L'arbre commun est couplé à celui de la machine par l'intermédiaire de paires de boîtes de vitesses pour augmenter la vitesse angulaire pour faire fonctionner la machine de manière plus efficace. L'eau tombe d'un terrain élevé à un terrain bas pour obtenir une vitesse tandis que le vent est accéléré en utilisant un accélérateur en forme d'entonnoir dans une tour éolienne pour atteindre des dizaines de mètres par seconde pour une conversion d'énergie efficace. Un mécanisme de levage est intégré au système afin d'exploiter l'énergie potentielle stockée dans le béton ou d'autres blocs lourds en l'absence de vent ou d'eau. Le système pourrait être modifié pour 1) exploiter l'énergie éolienne uniquement mais peut fonctionner en tant que moteur pour entraîner des charges mécaniques lorsqu'il n'y a pas de vent ; 2) exploiter l'énergie hydraulique et éolienne au bord d'une rivière ou d'un lac, sans recours au stockage gravitaire.
