Device for retriving energy of flowing water for the riverside

A device for retrieving energy of flowing water for the riverside, which is arranged at a riverside of a river, and the device for retrieving energy of flowing water for the riverside comprising:

• a rotating disk;
• a first rotating body and a first blade arranged at a first position of an upstream side of the river;
• a second rotating body and a second blade arranged at a second position of a downstream side of the river;
• a set of first connecting rods fixed to the first rotating body, an end of the set of first connecting rods is connected with the first blade, and another end of the set of first connecting rods is connected with the rotating disk;
• a set of second connecting rods fixed to the second rotating body, an end of the set of second connecting rods is connected with the second blade, and another end of the set of second connecting rods is connected with the rotating disk;
• and
• wherein water pushes the first blade under a surface of the water to swing from the first position to the second position, thereby rotating the rotating disk and reversely swinging the second blade over the surface of the water from the second position to the first position, the second blade sinks in the water, the water pushes the second blade to swing to the second position and rotate the rotating disk, thereby swinging the first blade over the surface of the water to the first position, and the first blade and the second blade alternately reciprocate and paddle to output a thrust of a stream, wherein the device is configured to be at a same side of the river, the first blade is provided with a paddling rod to sleeve one of the first connecting rods, and the second blade is provided with a paddling rod to sleeve one of the second connecting rods, each of the first rotating body, the second rotating body, and the rotating disk is fixed at the riverside using a fixing post, and the first rotating body is provided with a pulley and a horizontal sliding rod, the pulley is wound by a cord with two ends thereof respectively connected with the first blade and the first rotating body, and the fixing post is provided with a cord pushing rod, the cord pushing rod pushes the cord, and the cord pulls the first blade to rise using the pulley and the horizontal sliding rod.
