Wave-flow power installation // 2351793
FIELD: machine building.SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.EFFECT: wider functional capabilities of a power installation with orthogonal turbines.2 dwg
