Abstract

A wave-energy device comprises plates / walls 2 which are placed such that they form a narrowing channel and an inclined ramp 6 to amplify the wave energy. The wave climbs up the ramp, and flap valves 8 on the ramp open to divert water into reservoirs 9, 10, 11 when the water tries to flow back down the ramp. The reservoirs are preferably located at a height higher than the oncoming wave. The water stored in the tanks is channelled through turbines to extract the gathered potential / kinetic energy. The wave-energy device preferably is used to generate electricity to supply the grid or to drive a pump to raise the water to a higher lever for storage. Figure 1 shows a view between a frontal and plan view, while figure 2 shows a side-view where the wave would approach the ramp 6 from the right-hand side.

Description

This application concerns the use of wave power to store energy.
There exist a number of devices for utilising wave energy either to store energy or to generate electricity directly.
One such device is the uWave Dragon" which uses principles from traditional hydropower plants in an offshore floating platform to use wave energy.
The Wave Dragon consists of two wave reflectors that direct the waves towards a ramp. Behind the ramp, a large reservoir collects the directed water, and temporarily stores the water. The reservoir is held above sea level. The water leaves the reservoir through hydro turbines.
In this application the wave power is used rather differently. It is well known during tsunamis that when a wave reaches the shore if there is a bay then a focussing effect occurs and the wave height rises in proportion to the narrowing of the bay. In this application we set out to provide, on shore, exactly the same kind of effect so as to raise the height of the water considerably. As the power in a wave is proportional to the square of the height then the higher we can make the wave the better. The intention, therefore is to arrange the oncoming waves to be channelled, narrower and narrower and higher and higher so that the water acquires as much potential energy as possible. Along the channel are provided a number of moveable flaps which will be closed to allow the wave to move upwards and to open when the water attempts to flow back down. Behind each of these flaps the water can flow into reservoirs at different heights. The water can then be released through turbines and power generators to generate electricity or, for example, to pump the water into higher levels so that it can be used as a pumped storage scheme.
The equipment needs to be built into the shore line to gain the maximum effect from the waves but has a side benefit in that it will thus afford sea protection for the shoreline. The reservoirs created can also be used for a variety of purposes such as leisure sailing.
This invention refers to the manufacturing method and technique for making a wave power/pumped storage facility.
The principle of this invention is that the height of the incoming waves is enhanced by the equipment and the resultant water flow is into a reservoir sited at a significant height above sea level.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings (Figures 1 and 2). In Figure 1, 1 refers to the incoming wave, 2 refers to the wave enhancer plate angled to the direction of wave travel, 3 refers to the height of the incoming wave, 4 refers to the increasing height of the wave and the plate, 5 refers to the final height of the plate.
In figure 2, 6 refers to the plate across which the wave travels, 7 refers to the pivot for the flap (shown in the open position) which controls the flow of the water, 8 refers to the open flap that sends the water, that is flowing downhill, into the reservoirs 9,10 and 11. These are representations of reservoirs which would be of conventional construction and can be of any number and shape depending on the contours of the ground in the locality.

Claims (4)

  1. CLAIMSWhat we claim is 1. A method for the production of energy using the power contained in waves.
  2. 2. A method as claimed in claim I in which the wave height is enhanced using plates angled to the wave direction.
  3. 3. A method as claimed in claims I and 2 in which water from the enhanced waves is directed into reservoirs at a height greater than the original wave height.
  4. 4. A method as claimed in claims 1,2 and 3 in which the water from the reservoirs is used to make electricity to be used either directly through the grid or to pump water into a higher reservoir to be used for pumped storage.
