Abstract

L'invention concerne un dispositif de bouée de balisage utilisant l'énergie houlomotrice. Ce dispositif comprend une unité support, un disque sustentateur, une unité d'actionnement, une unité flottante et un organe de commande de clignotement. Dans l'unité support, des tiges supports inférieure et supérieure et deux tiges de guidage sont combinées verticalement, et une lampe de balisage est montée sur la tige support supérieure. Le disque sustentateur permet aux tiges de guidage de monter et de descendre. Des moyens d'actionnement actionnent un générateur à l'aide d'un mouvement relatif et chargent un accumulateur. Cette unité flottante contient les moyens de commande de façon étanche à l'eau dans un espace séparé.
