When the water pump 31 is stopped or the residual energy is insufficient, the motor 70 is started, and the motor 70 replaces the power output by the water turbine 32 to drive the stirring blade 43 to rotate and stir, so that the device is double-power input. In this alternative, as shown in fig. 2, two clutches 63 are provided, the principle of which is: when the water turbine 32 is input as power, the clutch 63 near the water turbine 32 is normally operated to perform power transmission; when the motor 70 is input as power, the clutch 63 near the motor 70 is normally operated to perform power transmission; when the motor 70 is operated in the reverse direction, the connected clutch 63 is disengaged, and no power is transmitted; from the energy saving point of view, only one of the water turbine 32 and the motor 70 is required to meet the operation requirement; when the turbine 32 and the motor 70 are operated simultaneously, the power is supplied at a high rotational speed, and the idle rotation is performed at a low rotational speed, which is not allowed, and a safety protection consideration point for the two clutches 63 is provided.
