Abstract

Föreliggande uppfinning avser en turbinkonstruktion för turbiner med självsvängande turbinblad för användning i applikationer där flödet i turbinen byter riktning (oscillerar) som t.ex. i vågenergibojkonstruktioner som utvinner sin kraft genom turbiner som oscillerar i vattnet med utnyttjande av ytvattnets sjöhävning. Därtill avser uppfinningen vågenergibojkonstruktioner med uppfinningens turbin (kallad Loqvist-turbinen) samt en princip för anläggande av och förankring av vågenergikraftverk som sammansätts av oscillerande turbiner under flytelement.The present invention relates to a turbine construction for turbines with self-oscillating turbine blades for use in applications where the flow in the turbine changes direction (oscillates) such as e.g. in wave energy buoy structures that extract their power through turbines that oscillate in the water using the sea level rise of the seawater. In addition, the invention relates to wave energy buoy constructions with the turbine of the invention (called the Loqvist turbine) and to a principle for constructing and anchoring wave energy power plants which are composed of oscillating turbines under floating elements.
