System for converting kinetic energy of aquatic currents naturally available across water in e.g. oceans, to rotation torque, has rotor rotated to cause flow of current to exert reverse pressure on blades to automatically open blades

摘要

The system has a parallelepiped tunnel (2) provided with a hydrodynamic deflector (11) that concentrates aquatic current (1) to rotate a rotor (3) with branches having blades (7-10) at ends. The blades move around vertical axles (12-15) of the branches. The rotation of the rotor causes the flow of current to exert pressure on the blades to automatically close the blades to generate rotation torque on a vertical axle (4) and to exert reverse pressure on the blade to automatically open the blades until the blades return to an end of the deflector and to a new torque generation position.
