DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a plant for recovering energy from waves in motion on the surface of a body of water.
A known plant of this type is described in SE Patent publication no. 443,026. In principle, this known plant comprises a semidomed, bell-like construction floating in the water and taking water in at the top. The water is guided to a reception pipe which guides the water to a turbine driving a generator for electrical energy. The known construction also provides the possibility of applying an elongated pipe extending parallel with the water surface and having the same diameter throughout its length, which pipe ends in a diffuser for a water outlet.
This plant is arranged to float partially submerged and the waves are caught by an upwardly-extending tower with openings in all directions allowing the water in the waves to run through the openings irrespective of the direction of the waves in relation to the plant. It is an unfavourable construction in respect of energy, as only a small part of the waves are caught; consequently, only a part of the wave energy is recovered.
Besides, this construction has not considered the principle that water seeks its own level, as the diffuser of the plant is placed in direct continuation of the horisontal pipe. A wave passing perpendicularly to this construction will stop most of the outlet.
SUMMARY OF THE INVENTION
The plant according to the invention has the advantage that the acquired device concentrates and utilizes the energy, i.e. both the kinetic and the potential energy in the waves, and guides the caught water to an energy converting engine without applying particular movable parts. Due to the design of the plant a large amount of water is collected currently throughout the length of the device, so that maximum energy recovery is achieved.
By designing the plant according to the invention it is ensured that the plant will not ride the waves, but that the waves will break over the plant. Furthermore, in the present invention the water admission velocity is increased through a plurality of reception funnels, so that the water reaches the turbine at an increased speed.
The water does not run out of the reception funnels when a wave has passed the plant.
The plant is preferably designed so that automatic regulation of the water admission to the turbine is obtained and the admission of water to the turbine is regular, even if there is a great distance between the waves.
Another objective of the present invention is that the recovered energy is optimized, as the direction of flow of the water is not changed substantially and the amount of water which would otherwise have passed over the plant is returned to the reception funnels.
Another objective of this invention is that great velocity of discharge of the water in the reception pipe is ensured.
A further objective is that the plant divides an admitted wave in such a manner that the plant is evenly loaded and the reception funnels are filled successively as the wave passes the plant, so that the admission of water is even; the admission of water to the water turbine will thus be even and constant.
BRIEF DESCRIPTION OF THE DRAWING
Other objectives and advantages of the invention will be apparent from the accompanying drawings in which:
FIG. 1 is a perspective view from the top showing the plant in general but partially intersected cut off at one side thereof;
FIG. 2 is a side view of the plant on a smaller scale shown floating in a body of water;
FIG. 3 is a sectional view on line III--III in FIG. 1;
FIG. 4 is a sectional view on line IV--IV in FIG. 1, and
FIG. 5 is a sectional view on line V--V in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a perspective front view of the plant in general according to the invention and in order to look into the construction its right side has been removed.
The plant comprises a float 2, a part of which is above the water surface 25 while the rest is below the surface. The plant is anchored to an anchor by means of an anchor
