This invention concerns to an axial flow turbine referred as to an hydroreactor, to take advantage of the kinetic energy from the water in relative depth places in rivers, estuaries or inlets, where the water streams are meaningful for the production of electric power. It is comprised by a conduit (1), inside which the water flows, a turbine impeller (2), a conduit support for said conduit (1), a rudder (17), a balancing weight (18), a bearing pedestal (22), a generator (8), coupled to said turbine impeller (2) by means of a transmission device (5, 6), a gearbox (7) and a centrifugal clutch, being the said turbine impeller (2) placed inside the said conduit (1) in which the water flows, the conduit support is comprised by a fixed part (15) well fitted over said bearing pedestal (22) solidary with four or more equally spaced hydraulic jacks (20) to lift the structure for maintenance proposes or depth control, and a mobile part (16), having a main body (16') which supports directly the conduit (1), a rudder (17) to drive the mobile part (16) according to the stream direction, and a balancing weight (18) to match the centre of mass of the mobile structure with the axis of the bearing pedestal (22), which together, define a system of supported immersed conduit for taking advantage of the stream, with a special shape, that will promote compression at entry side and suction effect by depression at exit side, easing the water flow through said conduit (1), the velocity through the impeller (2) being higher than the velocity of the outside stream before the conduit entrance (10), with autonomous rotation making it usable not only in rivers but also in estuaries or inlets, where the stream direction changes due to the tidal effect. <IMAGE> |
