Abstract:
1. A stationary installation for converting kinetic energy of tides into electricity in shallow waters and in narrow straits or rivers near coastal line utilizing Darrieus type in combination with funnel and consisting of a number of two-blade wheels staggered equally around 3600 and along of a common shaft, comprising: a group of submerged Darrieus turbines with funnels, having their horizontally located axis of rotation oriented perpendicular to direction of water current, and connected to a 90-degrees gearbox having output shaft oriented vertically and connected with a generator; is housed by an elongated structure having one end of it incorporated into shoreline; each of said group of Darrieus turbines have their turbines interconnected to each other through their axis of rotation by short shafts forming one common shaft; said elongated structure, having at least two support points and at least two pair of anchoring means undertaking current horizontal force, contains: a powerhouse, which is located above sea level and incorporated into shoreline is interconnected on its lower underwater part with the end of said common shaft of said group of Darrieus turbines, which protrudes from the end of said elongated structure coming to the shore line, contains: a generator, oriented vertically and located in the upper part of said powerhouse and interconnected with 90-degrees gearbox through a vertical shaft, said 90-degrees gearbox, which transmits horizontal rotation of said Darrieus turbines to said vertically oriented generator, and which is located on the bottom of said powerhouse and is interconnected with said end of said common shaft of said group of Darrieus turbines, means for keeping inner space of said 90-degrees gearbox from being flooded, a remote operating means for cleaning, cooling and changing oil in said 90-degrees gearbox means for cleaning Darrieus turbine blades from growth on their surface in a semi-automated mode.
