Description

FLOATING CONVERTER FOR SEA WAVES ENERGY
Technical Field
The present invention relates to a floating converter, in particular for sea waves energy transformation into electrical energy.
Background Art
Currently, there exist several families of floating converters, which are based on different principles of energy transformation as for example different floating systems, systems with air compression by the oscillating water column, different types of rafts with both hydraulic pumps and oil pressure generators etc.
A well-known converter, which, by its design, is similar to the claimed subject described below, is represented by' a floating converter on air cushion with an upper water reservoir for low pressure water turbines with electrical generators, whereby the converter is attached to a slanted ramp that is oriented against incoming sea waves and whose overflow edge is arranged above the upper water reservoir. On its lower side, the slanted ramp extends under the sea surface and directs the incoming sea waves to its aforementioned upper overflow edge in order to repeatedly fill the upper water reservoir. On its both sides, this well-known converter is further provided with two forward and sideward protruding guiding arms in a parabolic reflector shape (wave reflectors) whose task is to concentrate sea waves from larger area B of the sea surface against the slanted ramp, or on its overflow edge with a width b as the case may be. That should lead to an output rise corresponding to the relationship B : b. The middle part of the converter is, together with the water reservoir, maintained at the required height by means of an air cushion. ' " :
The drawbacks of such a converter consist, in particular, in the fact that the guiding arms connection to the middle part of the converter with the water reservoir is problematic, because in this connection area each incoming sea wave generates important relative shifts. The corresponding fixing elements that are anchored in the converter ferro-concrete structure are exposed to a combined cyclic stress, i.e. tension, compression, bending, and torsion in three directions. The limit of the fatigue strength of such a connection during cyclic strain that is estimated to three million cycles per year will be exceeded during a short time and a collapse of the device follows.
The function of the guiding arms is problematic too, because the waves returned by the arms are slowed down under this effect so that they can reach the converter' slanted ramp usually at the moment when portions of straight waves flow back on the slanted ramp. It results in wave collisions, thus resulting in an important loss of the kinetic energy of these delayed waves, which consequently are not able to get through the overflow edge of the converter's slanted ramp properly.
The most important drawback of the known converter and its accessories is the fact that it is built and assembled on;the open sea, i.e. usually with a turbulent sea surface. And the installation of the guiding arms that consist usually of individual ferro-concrete elements weighing several tons is possible only with large floating derricks and on a calm sea surface. On a rough sea the work has to be interrupted. The anchoring of the guiding arms has to be adapted progressively during the installation following the connecting process progress.'
Even maintaining the converter's middle part with the upper water reservoir in appropriate height relatively' to the sea surface by means of an air cushion seems to be problematic because important vertical shifts of the converter arise with changes of the water volume in the upper water reservoir. The pressure in the air cushion varies according to its charge and air pumps are not able to compensate the pressure quickly.
Nature of the Invention
The object of the present invention is to assure an efficient exploitation of the utilizable spectrum of the sea waves: kinetic energy for electric energy generation, whereas this objective is achieved by a new design of the converter with low pressure water turbogenerators, and whose principle consists of a pontoon being anchored to sea bed and equipped with an upper water reservoir with built-in suction orifices for water turbogenerators and with at least one longitudinal side being oriented towards incoming sea waves and to which a slanted" ramp with an upper overflow edge is assigned at and/or above the upper edge of the upper water reservoir, and this slanted ramp, which extends downwards under the sea surface, is equipped at its underside with a series of parallel entrance channels with inlet orifices that, in the shape of conical fillers, enter, by their upper outlets, in and/or above the upper edge of the upper water reservoir on the pontoon.
In this way, the kinetic energy of the sea waves is transformed into the potential energy. The water level in the upper water reservoir corresponds to the overflow edge on the slanted ramp and the height difference between the upper water reservoir and the sea level is < employed !fόr electric ■ 'energy -generation' by meanS Wf "at least !orie low-pressure water turbogenerator;' ' - ■' * ■ • '-• '• :-'_ {«---.ist *.:r. _- • . _ • • ... ...--.: ." ._ ...• i... • > y.-, ■ ,: -.■ ... ,\ . •.: _:.■ ;, ; . ;: . , :
According to this invention; it' 'ϊs of advantage for eliminating the potential effect of the counter-running wave interference, that in front, or possibly above the upper channel outlet openings, dispersion baffles are Arranged on the slanted ramp so as to allow to separate the overflowing upper parts of sea waves from the lower ones that are collected, while rushing into the upper water reservoir on the level of the upper overflow edge on the pontoon, into the inlet orifices. ! '
According to this invention, it is of particular advantage that the complete converter in the form of a pontoon is, including the slanted ramp, designed like a ferro-concrete skeleton with floating vessel capability that can be built in a dry dock. ■ ■; ■" '
It seems also to be of advantage* that folding extension plates can be attached to the lower edges of the entrance channel inlέt orifices in order to increase the collected portion of the secondary lower part of sea waves.' Description of the Figures in the Drawings
Further benefits and effects of the present invention are evident from the following drawings thereof wherein: Fig. 1 illustrates the outlined transversal vertical section of the anchored converter floating on the sea surface, with the suggested adaptation of the slanted ramp for overflowing of the upper part of the sea wave and collecting of the lower part of the same sea wave for its overflowing into the upper water reservoir on the converter pontoon,
Fig. 2 illustrates the sideward view on the slanted ramp arrangement with identification of entrance channel inlet orifices for the lower part of the sea waves and the upper dispersion baffles above the upper outlets of these entrance channels whose goal is to separate the overflowing upper parts of sea waves,
Fig. 3 illustrates the ground-plan outline view on the converter's skeleton with identification of transversal and longitudinal dividers under the converter's upper water reservoir, the inner arrangement of the slanted ramp, a facultative arrangement of the low pressure water turbogenerators and the converter's anchoring to the sea bed.
Examples of Carrying Out of the Invention
The converter I, in particular ifor the sea waves 2 energy transformation into electrical energy consists of the pontoon 6 that is freely anchored on the sea bed 3 by heavy concrete blocks 5 laid down on the 'sea bed 3, with the suction orifices 8 for low pressure water turbogenerators 9 that are provided in the bottom of the water reservoir 7 on the pontoon 6.
At least one longitudinal side of the pontoon 6 is oriented towards incoming sea waves 2 to which a slanted ramp Jj) with the* upper overflow edge ϋ at and/or above the upper edge 12 of the upper water reservoir 7 is assigned. The slanted ramp JO, which extends downwards under the sea surface, is at its bottom equipped with a series of parallel entrance channels JJ3 with inlet orifices 14, that, in the shape of conical fillers for example, enters by their upper channel outlets H into the slanted ramp H) on the level of the upper edge H, or into the upper water reservoir 7 on the level of the upper edge 12 on the pontoon 6. On their length, 'the" inner sides of the entrance channels 13 can be differently shaped. The folding extension plates 18 can possibly be attached to the lower edges of the inlet orifices 14 of the entrance channels 13 in order to increase the collection capacity of the secondary lower part 2" of the sea wave 2.

In front, or possibly above the upper channel outlets 15^ dispersion baffles 16 are arranged on the slanted ramp JO in order to separate the overflowing upper parts 2' of the sea waves 2 from the lower parts 2"of the sea waves 2, that are collected into the inlet orifices 14 while running into the upper water reservoir 7 on the level of the overflow edge H on the pontoon 6.
As noted above, due to the arrangement of the slanted ramp 10 having the entrance channels 13^ the incoming sea wave 2 is divided into two parts, it means into the upper part 2 ;';ιhavϊng: sufficient kinetic; energy land: which itself- runs : over -the1 upper overflow edge il_ into the' tipper watέr reservoir Φ^aiϊd into the lower part 2" having not sufficient kinetic energy, but as a result of its , penetration into the filler-like entrance channels YZ1 its kinetic energy increases under the local effect of Venturi 'phenomenon to that extent,- that its important: volume flows from the' upper channel outlets 15. into the upper water reservoir 7 on the pontoon 6 while surmounting the height difference between the sea level and the upper overflow edge H of the slanted ramp K). The energetic potential of the converter 1 raises through this additional exploitation of the whole utilizable spectrum of the kinetic energy of the sea waves 2 by approx. 15 to 30 %.
The complete converter 1, including the slanted ramp JjO, consists of the crate-like ferroconcrete skeleton with transportable vessel capability. The converter 1 that is designed like the pontoon 6 including the upper water reservoir 7 and the slanted ramp 10 is, for example, represented by a femr-concrete structure of horizontal slabs and vertical walls. The complete converter 1 including the slanted ramp JK) will be built on shore in a dry dock (here not depicted) and after having been equipped with at least one low pressure water turbogenerator 9 will be transferred from the dry dock to its destination like a vessel. The following installation of the converter 1 consists in its anchoring, for example by means of the ropes 4 and the heavy weights 5_ or other suitable anchoring means. Such an operation does not require1 any other on-site work and can be done even if the sea is slightly choppy. In case of a rough sea with huge waves 2 during thunderstorms a temporary overflowing of the entire converter 1 may be accepted without causing serious damage to the entire installation.
In the ferro-concrete structure of the pontoon 6 various caverns or chambers 17 are
5 possibly created, which can be flooded in a controlled way in order to balance the pontoon
6 or to adapt its draft with the intention to ensure an adequate sea-gauge of its slanted ramp
10 with regard on both characteristics and heading-up of the incoming sea waves 2 etc. The bottom of the upper water reservoir 7 can be extended in inclination towards the low pressure water turbogenerators 9, and such a solution, in addition to the raise of immediate
10 water supply, provides a possibility to compensate the mass of the protruding slanted ramp
10, if this one were neither designed like a floating structure nor supported in another way. ! ::::.Y \~>J '...*■. :, •/■/ ι/;.i;.-:it.:'. :ιc -.1..1L.-'
The converter 4 is held- on the surface by its draft, which is done automatically according to known Archimedes' Law. The energetic head difference (a height difference between
