Water driven power generator mounted on moored raft - has rotor shafts above water level coupled to common generator

摘要

The power generator comprises a moored raft (1) carrying a number of bladed rotors (12, 13) arranged one behind the other in the direction of the water current, The rotor shafts (15, 16) are above water level and at right angles the current, and are coupled to the drive shaft (24) of a common generator (11) on the raft via transmission means (19, 20, 22, 23). The raft may be carried above water level by streamlined floats (5, 6) arranged on either side of the rotor and extending in the direction of the current.
