Title:
SINGLE BUCKET DRAG-TYPE TURBINE AND WAVE POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2014/076782
Kind Code:
A1
Abstract:
[Problem] To provide: a drag-type turbine that is capable of efficiently extracting the rotational kinetic energy of fluid particles in waves; and a wave power generator equipped with the drag-type turbine. [Solution] This single bucket drag-type turbine is equipped with a single semi-cylindrical bucket, and a counterweight opposing the bucket. The bucket and the counterweight, which are impelled by rotationally moving fluid particles in waves, rotate as a unit. Given that the counterweight opposes the bucket, when the bucket and counterweight rotate as a unit, even if the bucket and counterweight are present in a flow velocity vector of substantially the same phase, as long as the counterweight is given a shape having little resistance, the force received by the bucket from fluid particles will be much larger than the force received by the counterweight from the fluid particles, and the two forces will not offset each other. The single bucket drag-type turbine is thus able to efficiently extract the rotational kinetic energy of fluid particles in waves.
