Hydroelectric installation driven by e.g. ocean current, comprises underwater vortex turbine with rotor tube driving speed increasing gear connected to dynamo

摘要

The rotor part driven by the running water is used to drive an automatic speed-increasing gear, which is connected to and drives a dynamo. Water is made to flow through the stator tube, which is mounted on an eccentric rotary point so that this tube is positioned parallel to the flow direction in the same manner as a wind vane. The rotor tube can rotate inside the stator tube and is provided with a screw profile on its inner side. The outside of this underwater vortex turbine installation is straight and the inside is ball-shaped, increasing flow on the inside.
