ABSTRACT:
A speed-increasing machine for water includes a frame member, a plurality of buoyant members mounted to the lower end of the frame member, a motor mounted to the center of the frame member, and a shielding cover mounted outside the motor. A rotating shaft of the motor is attached to a guide vane set. The guide vane set has a plurality of guide plates for guiding the circulating water current. When driving the motor, the vanes rotate to circulate the water in the cultivation pool, to thereby uniformly increase the dissolved oxygen in the cultivation pool.
