Abstract

resumo "dispositivo de geração de energia a partir da corrente oceânica do tipo flutuante submerso" é fornecido um dispositivo de geração de energia a partir da corrente oceânica do tipo flutuante submerso com o qual é possível suprimir a vibração direcional cíclica de um corpo flutuante de um dispositivo de geração de energia a partir da corrente oceânica, causada por momentos de sombra. um dispositivo de geração de energia a partir da corrente oceânica do tipo flutuante submerso inclui corpos principais (2) do dispositivo de geração de energia a partir da corrente oceânica, cada um incluindo um rotor de um gerador de energia (9) alojado em uma nacela (4), e uma estrutura. o rotor é configurado para ser acionado por uma pá rotativa (5) que se projeta para fora a partir da nacela (4). um corpo flutuante de tambor duplo (1) capaz de flutuar sob a água é constituído pela estrutura e pelos corpos principais (2) do dispositivo de geração de energia a partir da corrente oceânica unidos à esquerda e à direita da estrutura. o dispositivo de geração de energia a partir da corrente oceânica do tipo flutuante submerso é amarrado a um leito oceânico por uma corda de amarração. cada um dentre os corpos principais (2) do dispositivo de geração de energia a partir da corrente oceânica usa um sistema a sotavento no qual a pá rotativa (5) é disposta mais a jusante na direção da corrente oceânica do que a nacela (4) e compreende um meio de supressão de momento (20) configurado para suprimir momentos que são criados no corpo flutuante (1) como resultado da redução da força de propulsão que acompanha a redução da velocidade da corrente oceânica que ocorre quando uma pá (5a) das pás rotativas (5) entra em uma região de sombra (região de momento de sombra) da estrutura em um lado a montante da direção da corrente oceânica.
