1. A hydropower equipment with graded utilization of kinetic energy of flowing water, comprising a triangular base and three runners, an inclined surface of the triangular base being a segmented smooth surface, three steps being formed from top to bottom on the inclined surface, a vertical surface of each of the steps being equipped with support rods, and runner one, runner two and runner three of the three runners arranged from high to low being rotatably supported on the corresponding support rods through shafts, and the three shafts all horizontally arranged and connected to corresponding shafts of generators separately; horizontal flow channels being set inside a lower part of the triangular base for guiding water to flow toward downstream direction, and outlets of the horizontal flow channels directly face a curved part of the blades of runner three.
