Abstract

L'invention porte sur un mécanisme à énergie éolienne à anneau excentrique qui comprend plusieurs ensembles planches éoliennes (13), un ensemble entraînement de liaison (14) et un anneau mobile (16) apte à se déplacer horizontalement. La partie d'extrémité du côté interne de l'ensemble planche éolienne se déplace dans une fente de guidage (17) de l'anneau mobile (16) sous l'effet du vent. Les ensembles planches éoliennes (13) sont montés à la périphérie de l'ensemble entraînement de liaison (14) d'une manière rotative, sont fixés sur l'ensemble d'entraînement de liaison (14) et entraînent l'ensemble entraînement de liaison (14) en rotation. Simultanément, les planches internes des ensembles planches éoliennes (13) exercent une pression sur l'anneau mobile (16) dont la force qui en résulte va déterminer la position de l'anneau mobile (16), de telle sorte que les ensembles planches éoliennes soient toujours maintenus à la position la plus adéquate au moment où ils sont soumis au vent, et ce, afin à améliorer le rendement d'utilisation d'énergie éolienne.
