Abstract

O presente invento descreve uma turbina para extrair energia de um escoamento bidireccional alternado, como é o caso de sistemas de conversão de energia das ondas marítimas. A turbina tem um rotor de pás com duas aberturas na sua periferia em cada uma das quais se dá alternadamente entrada e saida de fluido, sendo radial centrípeto o escoamento à entrada e radial centrífugo o escoamento à saida. O estator admite duas configurações que promovem a deflexão do escoamento de aproximação ao rotor com criação duma componente circunferencial de velocidade do fluido com o mesmo sentido que o da rotação normal do rotor, procurando em ambos os casos minimizar a perturbação do escoamento de saida. Numa das configurações, as pás de guiamento estão próximas do rotor e deslocam-se axialmente conforme o sentido do escoamento, de modo a guiarem o escoamento de entrada e não interceptarem o escoamento de saída. Na outra configuração, as pás de guiamento estão fixas axialmente e estão radialmente afastadas do rotor.

Claims

REIVINDICAÇÕES MODIFICADAS Recebidas pela Secretaria Internacional no dia 13 JAN 2012 (13.01.2012)
1. Turbina para escoamento bidireccional de sentido alternado que compreende um rotor com pás (2) e um estator (18, 19) com pás de guiamento, a turbina tendo um eixo, estando o referido rotor montado rotativamente para girar em torno do eixo e tendo uma multiplicidade de pás dispostas circunferencialmente no exterior do rotor, caracterizada por compreender:
• as referidas pás (2) formando canais de escoamento entre a entrada e a saida do rotor, tendo o referido rotor na sua periferia exterior duas zonas de abertura (5, 6) axialmente afastadas uma da outra, a entrada de fluido no rotor através de qualquer uma das duas zonas de abertura sendo centripeta e a saida do fluido para fora do rotor através de qualquer uma das duas zonas de abertura sendo centrífuga;
• um primeiro conjunto de pás de guiamento (7) dispostas circunferencialmente em torno do eixo e localizadas num raio maior em relação à respectiva zona de abertura do rotor no trajecto do escoamento de aproximação ao rotor ou provindo dele;
• uma conduta (9) que liga o primeiro conjunto de pás de guiamento (7) à correspondente zona de abertura do rotor, formada preferencialmente por paredes de revolução (10, 11) ; ● um segundo conjunto de pás de guiamento (8) dispostas circunferencialmente em torno do eixo e localizadas num raio maior em relação à respectiva zona de abertura (6) do rotor no trajecto do escoamento de aproximação ao rotor ou provindo dele;
● uma conduta (12) que liga o segundo conjunto de pás de guiamento (8) à correspondente zona de abertura (6) do rotor, formada preferencialmente por paredes de revolução (13, 14);
2. Turbina de acordo com a reivindicação 1, na qual uma conduta (9), formada preferencialmente por paredes de revolução (10, 11), está disposta externamente no alinhamento do primeiro conjunto de pás de guiamento (7) e liga-a ao espaço do fluido exterior.
3. Turbina de acordo com a reivindicação 1, na qual uma conduta (12), formada preferencialmente por paredes de revolução (13, 14) , está disposta externamente no alinhamento do segundo conjunto de pás de guiamento (8) e liga-a ao espaço do fluido exterior.
4. Turbina de acordo com qualquer uma das reivindicações anteriores, na qual os dois conjuntos de pás de guiamento (7, 8) do estator (18, 19), dispostos circunferencialmente no exterior do rotor, são moviveis com translação axial, de modo que cada um dos conjuntos de pás de guiamento possa ser inserido no escoamento de aproximação ao rotor e retirado do escoamento de saida do rotor, sendo a distância radial entre o rotor e as pás de guiamento preferencialmente pequena.
5. Turbina de acordo com a reivindicação 1 na qual, no estator, o ângulo de posicionamento das pás de guiamento de cada um dos dois conjuntos pode ser variável, preferentemente controlado por um mecanismo de anel e barras articuladas do tipo comummente utilizado no distribuidor das turbinas hidráulicas de tipo Francis e Kaplan .
6. Turbina de acordo com qualquer uma das reivindicações anteriores, na qual os canais formados pelas pás do rotor são limitados exteriormente ao longo de toda a periferia :
• por um invólucro (15) ligado rigidamente às próprias pás do rotor (2),
• ou por um invólucro (16) fazendo parte do estator.
