Abstract: A device for retrieving energy of flowing water for the riverside is disclosed. The device uses a rotating disk to respectively connect with a first blade and a second blade through two rotating bodies. The first blade and the second blade are respectively located at the first position of an upstream side and the second position of a downstream side. Water pushes the first blade under the surface of water to swing from the first position to the second position, thereby rotating the rotating disk by a rotating distance. Thus, the second blade originally arranged over the surface of water reversely swings to the first position. Then, the second blade sinks in the water. Water pushes the second blade to swing to the second position, and the first blade rises and leaves the surface of water to swing to the first position.
