BRIDGE Russian patent published in 2017 - IPC E01D1/00 

FIELD: construction.

SUBSTANCE: horizontal shaft is mounted in the projection and the stand. Blades are attached to the shaft. A gear is mounted on the shaft. A gear in contact with the gear is mounted on the electric generator shaft. Water flowing around a support pushes the blade. Voltage is generated on the electric generator stator and supplied to the power line. In winter, the time relay supplies the voltage to winches. Tanks located on the water float off under the flow action from their winches, unwinding the cables. Then the time relay supplies the voltage to the winches electric motors. The tanks return upstream, respectively, to the winches. The tanks break the ice with teeth in front of the blades, on the sides of the blades and behind the blades. Thus, the blades rotate continuously in water free from ice.

EFFECT: bridge of the proposed design generates electricity of high power.
