Wave power plant

Abstract

The invention relates to a wave power plant, comprising at least one float or pontoon (1) or a plurality of interconnected floats or pontoons (2). The float or pontoon (1) is shaped or the interconnected floats or pontoons (2) are disposed asymmetrically relative to the advancing direction of waves, such that the float or pontoon (1) or a member (3) linking the interconnected floats or pontoons is set in a gyrating motion in response to the buoyancy of a succession of waves advancing in said direction. The wave power plant includes elements (5, 6, 7; 9, 10) for converting the gyrating motion into a rotational motion for power take-off.

Description

technical field

[0001] The invention relates to an ocean wave power generation device, which comprises at least one float or pontoon or a plurality of connected floats or pontoons.

[0002] In an alternative embodiment of the present invention, the ocean wave power generating device comprises anchored underwater blades. Background technique

[0003] Document US-4,266,143 discloses a sea wave power plant with the aim of converting the side-by-side tilting of a pontoon into a rotational movement of two very heavy gravity wheels rotating in opposite directions. The pontoons are symmetrical and the gravity wheels are set in opposite orientations to ensure that only side-by-side tilting occurs.

[0004] A problem with this and other known wave power devices is the random motion of the waves and fluctuations in wave size. It is difficult to efficiently convert this reciprocating motion into continuous rotational motion. Contents of the invention
