<p>Underwater paddle wheel, which contains a frame (1) and a rotor (2) mounted therein, which rotor (2) has a rotor shaft (3) supported on bearings in the frame (1), a number of rotor elements (5) situated axially next to one another which each contain at least one vane (6) which determines a main blade surface which extends through the rotor shaft (3) and which consists of at least one support (7, 9) fixed on the rotor shaft (3), at least one blade (10) which is hinge-mounted in relation to the support (7, 9) around a hinge pin (11) which is parallel to the rotor shaft (3) and a stop (12) for the blade (8) which is fixed on the support (7, 9) and is situated almost in the main blade surface, whereby at the ends of the rotor (2) and in between neighbouring rotor elements (5) are situated bulkheads (19, 20) which are fixed in relation to the frame (1), are directed diagonally on the rotor shaft (3) and extend at least over a large part of half of the rotor (2) where the vanes (6) are active, i.e. where the blade (10) of these vanes takes up the position in which it links up against the stop (12), characterized in that the frame (1) contains a bottom piece (18) which extends in the axial direction under at least almost the entire length of the rotor (2) and in that the bulkheads (19 and 20) are placed directly on this bottom piece (18).</p> |
