Claims (7)

1. Bølgeenergianlæg til udvinding af energi fra bølgebevægelsen i en vandoverflade, hvilket bølgeenergianlæg omfatter en stelkonstruktion, hvori der er lejret i det mindste en rotor, og hvor rotoren er ophængt i stelkonstruktionen på en i bølgeenergianlæggets normale brugssituation i hovedsagen vandret rotoraksel, således at rotoren kan rotere om rotorakselen, som fastholdes i stelkonstruktionen, og hvor der er indrettet midler til at holde hver af rotorerne delvist neddykket i en vandoverflade, KENDETEGNET VED, at rotoren er monteret på rotorakselen via en friløbsmekanisme, som er indrettet på en sådan måde, at rotoren i hovedsagen kun kan overføre en momentbelastning på rotorakselen, når den roterer en vej omkring rotorakselen.A wave energy system for extracting energy from the wave movement in a water surface, said wave energy system comprising a grounding structure in which at least one rotor is mounted and the rotor is suspended in the grounding structure of a substantially rotor shaft in the normal use situation of the wave energy plant, may rotate about the rotor shaft which is retained in the frame structure and where means are provided for holding each of the rotors partially submerged in a water surface, characterized in that the rotor is mounted on the rotor shaft via a free-running mechanism arranged in such a way that the rotor can only transmit a torque load on the rotor shaft only when it rotates one way around the rotor shaft. 2. Bølgeenergianlæg ifølge krav 1, KENDETEGNET VED, at der på rotorakselen er indrettet to eller flere separate rotorer, som er monteret på en fælles rotoraksel ved hjælp af hver sin separate friløbsmekanisme.2. Wave energy system according to claim 1, characterized in that two or more separate rotors are mounted on the rotor shaft, which are mounted on a common rotor shaft by means of each separate free-running mechanism. 3. Bølgeenergianlæg ifølge krav 2, KENDETEGNET VED, at hver rotor omfatter to gavle, og hvor afstanden mellem gavlene på rotorerne er mindre end 2 meter og fortrinsvis mindre end 1½ meter.3. Wave energy system according to claim 2, characterized in that each rotor comprises two gables and the distance between the gables on the rotors is less than 2 meters and preferably less than 1½ meters. 4. Bølgeenergianlæg ifølge krav 3, KENDETEGNET VED, at stelkonstruktio-nen omfatter to eller flere rotormoduler, som hver omfatter et stel og en rotoraksel, og hvor hvert af rotormoduleme derudover er forsynet med fastgørelsesmidler, som er indrettet med henblik på at montere rotormodulerne til hinanden på en sådan måde, at rotoraksleme strækker sig i hinandens forlængelse, og hvor der er indrettet midler til sammenkobling af rotorakslerne til dannelse af en fælles rotoraksel for to eller flere af rotormoduleme.Wave energy system according to claim 3, characterized in that the frame structure comprises two or more rotor modules, each comprising a frame and a rotor shaft, and each of the rotor modules additionally being provided with fasteners arranged for mounting the rotor modules to each other in such a way that the rotor shafts extend in each other's extension and where means are provided for interconnecting the rotor shafts to form a common rotor shaft for two or more of the rotor modules. 5. Bølgeenergianlæg ifølge krav 4, KENDETEGNET VED, at gavlene på to eller flere rotorer alene er adskilt af en lysning, som netop tillader, at to hosliggende vandmøllehjul kan rotere frit i forhold til hinanden omkring rotorakselen.Wave energy system according to claim 4, characterized in that the gables on two or more rotors are separated only by a groove which allows two adjacent watermill wheels to rotate freely relative to each other around the rotor shaft. 6. Bølgeenergianlæg ifølge et eller flere af de foregående krav, KENDETEGNET VED, at friløbsmekanismen omfatter en skraldemekanisme, som alene tillader rotoren at rotere omkring rotorakselen i en retning, og ikke i den modsatte retning.Wave energy system according to one or more of the preceding claims, characterized in that the free-running mechanism comprises a ratchet mechanism which only allows the rotor to rotate about the rotor shaft in one direction, and not in the opposite direction. 7. Fremgangsmåde til opbygning af et bølgeenergianlæg ifølge et eller flere af de foregående krav, KENDETEGNET VED, at gavlene på et eller flere af rotorerne er placeret i en indbyrdes afstand, der er mindre end afstanden mellem to bølgetoppe og fortrinsvis mindre end halvdelen af afstanden mellem to bølgetoppe i forhold til en for bølgeenergianlægget normal driftssituation.A method of constructing a wave energy plant according to one or more of the preceding claims, characterized in that the gables on one or more of the rotors are located at a mutual distance which is less than the distance between two wave peaks and preferably less than half the distance. between two wave peaks relative to a normal operating situation for the wave energy system.
