METHOD AND DEVICE "WAVE TURBINE USTJUG" Russian patent published in 2007 - IPC F03B13/14 

FIELD: hydraulic power engineering.

SUBSTANCE: proposed method and device "wave turbine USTJUG" are designed for converting energy of sea waves into mechanical energy rotating the turbine. Turbine is arranged in deep still layers of water, and float holding turbinerotating shaft but not taking part in its rotation is located on water surface tasking part in wave motion. Displacements of float are transmitted through rotating shaft by means of rigid longitudinal tie with turbine, thus setting turbine into rotation. Owing to flexibility of blades, turbine moves always in one direction. Chords of blades at rest are located in plane of turbine rotation, and in active state, blades flex like wing of bird or tail of fish at stroke cross to direction of motion. Gripping of blade and power action from float to blade is provided according to rule U=0.29 in direction cross to plane of blade motion. Blades are arranged in pairs symmetrically relative to rotating shaft on crossmember to form separate element of turbine with torques of same signs for both blades number. Of such elements arranged along turbine rotating shaft determines power of turbine rising in proportion of number of turbine elements whose relative arrangement in angle of plane of rotation and element-to-element distance of rotating shaft is determined to provide maximum efficiency of elements in operation.

EFFECT: effective conversion of wave energy and reliability in operation.
