Claim:
Floating paddlewheel aerator for aerating water and clearing basins, comprising a frame ( 1 ) containing elongated floats ( 2 , 3 ) and comprising at least one drive unit ( 9 ) supported by the frame with an output shaft ( 10 ) and paddles ( 22 ) mounted on this shaft, during operation of the aerator the floats floating on the surface of the water or clearing basin, the shaft rotating above the level of the water or clearing basin and parts of the paddles rotating with the shaft being immersed into the liquid, characterized in that the floats ( 2 , 3 ) form the frame ( 1 ), are substantially arranged at a right-angle to each other and connected with each other in a configuration where at both opposite longitudinal sides of a first float ( 2 ) further floats ( 3 ) or float sections are mounted and that said first float ( 2 ) on its top side, which if compared with the longitudinal sides at which the further floats/float sections ( 3 ) are located, is turned upwards by 90°, partially or completely carries the drive unit ( 9 ) whose output shaft ( 10 ) projects on both sides and parallel to the longitudinal direction of the further floats/float sections ( 3 ) and is the shaft carrying the paddles ( 22 ).
