Description

Foreliggende oppfinnelse angår en innretning for omforming av bevegelsesenergien i sjøbølger til nyttig energi for eksempel elektrisitet. The present invention relates to a device for transforming the movement energy in sea waves into useful energy, for example electricity.

Innretningen består av et masse - fjær svingesystem som omfatter to vannkammer (1, 2) som er koblet til en flottør (3) via fjærforbindelser (4a) og bremser (4b). Flottøren (3) er videre forankret til en undervannsbøye (9) via en line (7), fjærer (4a) og bremser (4b). Bøyen (9) er via en line (10) forankret til fundamenter (14) på havbunnen. The device consists of a mass - spring swing system comprising two water chambers (1, 2) which are connected to a float (3) via spring connections (4a) and brakes (4b). The float (3) is further anchored to an underwater buoy (9) via a line (7), springs (4a) and brakes (4b). The buoy (9) is anchored via a line (10) to foundations (14) on the seabed.

Masse - fjær systemet har en egenfrekvens som er lik eller lavere enn frekvensen til sjøbølgene. Når flottøren (3) blir påvirket av sjøbølger vil komponentene (1, 2, 3) svinge i vertikal retning i forhold til hverandre. I tillegg vil nevnte komponenter og bøyen (9) svinge noe i horisontal retning. Ettersom masse - fjær systemet har en egenfrekvens som er lik eller lavere enn frekvensen til sjøbølgene vil det bli overført energi fra sjøbølgene til masse-fjær systemet. Energien tas ut ved bruk av bremsene (4b) som automatisk justerer bremsekreftene slik at de tilsvarer de kritiske dempingskreftene til masse - fjær svingesystemet. Bremsekraften brukes til å generere elektrisk energi. The mass-spring system has a natural frequency that is equal to or lower than the frequency of the sea waves. When the float (3) is affected by sea waves, the components (1, 2, 3) will swing in a vertical direction in relation to each other. In addition, said components and the buoy (9) will swing slightly in a horizontal direction. As the mass-spring system has a natural frequency that is equal to or lower than the frequency of the sea waves, energy will be transferred from the sea waves to the mass-spring system. The energy is extracted by using the brakes (4b) which automatically adjust the braking forces so that they correspond to the critical damping forces of the mass - spring swing system. The braking force is used to generate electrical energy.

Det er tidligere kjent masse - fjær svingsystem for utvinning av energi fra sjøbølger. Det vises til tidligere patent nr. 330490 som viser et masse - fjær svingesystem som utnytter energien i vertikale og horiontale bevegelser. Foreliggende oppfinnelse er en forbedring i forhold til tidligere teknologi ved at den inkluderer en praktisk løsning for forankring av bølgekraftinnretninger på sjø eller hav med stor dybde. I tillegg utnyttes energien i de horisontale bevegelsene mellom bøyen (9) og flottøren (3). It is a previously known mass-spring swing system for extracting energy from sea waves. Reference is made to earlier patent no. 330490 which shows a mass - spring swing system which utilizes the energy in vertical and horizontal movements. The present invention is an improvement in relation to previous technology in that it includes a practical solution for anchoring wave power devices on seas or oceans with great depth. In addition, the energy is utilized in the horizontal movements between the buoy (9) and the float (3).

For en ytterligere beskrivelse av foreliggende oppfinnelse henvises det til vedlagte tegninger som viser flere bølgekraftinnretninger koblet til et felles forankringssystem. Figur 1 og 2 viser et bølgekraftanlegg bestående av fire bølgekraftinnretninger sett fra siden og i perspektiv. For a further description of the present invention, reference is made to the attached drawings which show several wave power devices connected to a common anchoring system. Figures 1 and 2 show a wave power plant consisting of four wave power devices seen from the side and in perspective.
