Floating body impeller type surge machine

The invention discloses a floating body impeller type surge machine which comprises a motor, a gear box connected with the motor, and a floating body impeller connected with the gear box. The floating body impeller type surge machine is characterized in that the floating body impeller comprises an annular floating body, and a plurality of blades are arranged on the outer side below the annular floating body. The invention can ensure that bottom water in a pool is lifted to the surface of the pool at low velocity and large flow during the work, a large range of waves are formed while a water body is subjected to oxygenation under the action of the blades of the floating body impeller, and disperse along the surface without blockage, thus the oxygenation of the bottom water is promoted and the harmless speed of harmful substances is increased.
