Definitions
- This invention relates to a wave power station, in which there are arranged, at several levels, reservoirs which the water of the waves flows into.
- the water flows on through low-pressure turbines arranged typically for the production of electrical power.
- Ocean waves occur through conversion of part of the wind energy across ocean areas.
- the wave energy calculated per surface area is essentially greater than the solar and wind energy in the same area. Utilization of wave energy from the ocean therefore constitutes an almost inexhaustible, renewable source of energy, and it is the only pure energy source which may potentially replace today's consumption of fossil fuels.
- a wave power station based on the wedge chute principle stand out as a simple and reliable plant. Simplified the system may be explained as the incoming waves being forced inwards between the two cuneiform side edges, whereby the maximum height of the waves increases.
- a collecting basin At the narrowest end portion of the wedge, at a level above the sea surface is arranged a collecting basin. Wave crests exceeding this level, flow over the edge of the basin and fill the basin. The drop of the water between the collecting basin and sea level is utilized in a conventional manner by means of a low-pressure turbine.
- the invention has as its object to remedy the drawbacks of known technique.
- the object is achieved, according to the invention, through the features set forth in the description below and in the following Claims.
- a wave power station utilizes the kinetic energy of a wave by lifting it as high as possible up a ramp.
- the ramp is divided into segments by means of vertical walls and provided with through openings which may guide the wave water down into one of several reservoirs located one above the other.
- the openings in the bottom of the ramp is of such configuration with respect to direction and size, that water flowing up the ramp will flow across the openings, whereas water flowing down the ramp will run down through the nearest opening and down into the corresponding reservoir. From each reservoir the water flows through a turbine located below and back to sea level.
- the wave power station may be of such configuration that it is suitable for example for fixed installation along a beach, built into a pier arrangement or for fixed/floating installation in open waters.
- the power station is configured as a relatively flat truncated cone.
- the conical cone surface forms the ramp mentioned above.
- Projecting up from the cone surface a number of walls radiate radially outwards from the top of the cone.
- the walls may extend further out than to the outer periphery of the cone.
- the bottom of each cuneiform chute is provided with a number of openings communicating with one of the basins preferably located on the same level in the interior of the cone.
- Necessary pipe connections, turbines and other machinery may be positioned in a central part which extends from the top of the cone down to the sea level.
- At least one of the wedge chutes of the wave power station will be arranged to receive waves moving towards the power station from any direction.
- Fig. 1 shows in perspective a floating wave power station according to the invention
- Fig. 2 shows a schematic vertical section of the wave power station according to Fig. 1, from the centre line of the power station radially outwards;
- Fig. 3 shows a schematic vertical section like that in Fig. 2 on a larger scale in an embodiment in which the through openings are provided with dampers;
- Fig. 4 shows a schematic vertical section like that in Fig. 3, but here the dampers are closed.
- the reference numeral 1 identifies a wave power station, in which the external geometry of the power station is essentially constituted by a truncated cone 2 which may be floating on the sea surface 3 or fixedly mounted to the sea bed.
- An operating/control room 4 may be placed above the top of the cone 2 and serve at the same time as access and roof for a machine room 6 underneath.
- the lower portion of the cone 2 is provided with buoyancy tanks 9.
- the cone sector/ramp 12' is provided with a through opening 16 at the very top, and several directional openings 17 located below. Each of the openings 16 and 17 communicates with one of the reservoirs 18, 18', 18" and 18''' positioned one above the other inside the cone. In Fig. 2 are shown four reservoir levels. The number must be adjusted according to the dimensions of the power station and the existing wave sizes and frequencies.
- the directional openings 17 are directed towards the highest end portion of the ramp 12' of the wave power station, and sloping gently inwards in a preferred embodiment.
- Pipe connections 22, 22', 22" and 22''' connect a respective one of the reservoirs 18, 18', 18" and 18''' to their respective low-pressure turbines 24, 24', 24" and 24 1 ' 1 .
- the openings 17 are provided with one or more butterfly dampers 26 hinging on hinge axles 28.
- the area of the upper portion 30 of the damper 26, located above the hinge axle 28, is smaller than the area of the lower portion 32 of the damper 26, located below the hinge axle 28.
- the dampers 26 are arranged to be closed in that the entering wave forces the upper portion 30 of the damper down. When the wave stops, the water pressure against the larger area 32 makes the damper turn into the open position.
- the wave water must be utilized in the turbine immediately because no reservoir is installed.
- the turbines may be sized for a fixed drop, by which higher efficiency is achieved by means of a relatively simple turbine.
