METHOD FOR CONVERTING THE ENERGY OF WATER WAVES INTO ELECTRICITY BY MEANS OF A WAVE POWER PLANT AND A WAVE POWER PLANT

Document Type and Number:

WIPO Patent Application WO/2013/156674

Kind Code:

A3

Abstract:

A method for converting the energy of water waves into electricity by means of a wave power plant and a wave power plant, which comprises a floating body (1), a rotator (3) which is supported on the body and rotates around a rotator shaft (2) which is on average vertical, a gyro (5) which rotates around a gyro shaft (4) which is on average horizontal, the gyro and the gyro shaft rotating with the rotator around the rotator shaft (2), and at least one generator (6), which is connected to rotate together with the gyro or the rotator. By means of the rotator's mass (M) is produced a moment rotating the rotator on the one hand by means of the inclination moment generated by the inclination of the body and gravitation, and on the other hand by means of the acceleration moment generated by the horizontal acceleration of the rotator shaft (2). The inclination and acceleration are caused by directing the internal flows of the wave at the submerged part of the body (1). The moment generated by gyro force is used to equalize the said inclination and acceleration moments during the revolution and the kinetic energy of the gyro is used as an energy reserve to equalize the effective output of the wave power plant.
