WAVE POWER DEVICE

摘要

The invention relates to a wave power device 1 for the extraction of energy from waves in a liquid 3. The device 1 comprises a container 2 intended to at least partially be located in the liquid 3 from which the wave energy shall be extracted. The container 2 is provided with one or several openings 6, for admitting said liquid 3 and gas 5 into the container and at least one outlet 8. The container 2 is at least partly designed as an oblong unity adapted to be influenced by and essentially follow the wave motions in the liquid 3 so that the container 2 assumes a wave shaped contour. The container 2 will assume positions having different potential energy relative each other in at least a first portion 9 and a second portion 10. By the wave motion will liquid 3 and gas 5 be transported through the tubular container while a pressure is built up within the container 2. The invention is in particular directed to the design of the container 2 which shall be designed so that it is along at least a portion of its length its width B is larger than its height a in order to reduce friction losses in the plant considering practical limitations in allowable height of the container in relation to wave height.

1. A wave power device for the extraction of energy from wave motion in a liquid which device comprises a container intended to at least partially be located in said liquid from which the wave energy is extracted, said container provided with one or several openings for admitting said liquid and a gas into the container and at least one outlet whereby said container at least partly is designed as an oblong unit adapted to be influenced by and essentially follow said wave motion so that the container will assume a wave shaped contour wherein the container in at least a first portion and a second portion assume positions with different potential energy relative each other so that a pressure is built up within the container by the use of the liquid and the gas which flows towards the outlet influenced by said wave motions whereby energy in said flow is extracted by an energy converter connected to the container, wherein the container at least along a part of its length is designed so that it width is larger than its height.
