WAVE PUMP Russian patent published in 2003 - IPC

FIELD: hydraulic engineering. SUBSTANCE: proposed pump is designed for lifting deep waters to surface of water reservoir and saturating water with oxygen using energy of waves. Pump is provided with float with central hole in which vertical pipe with check valve is secured and container arranged in upper part of pipe opened from lower end face and enclosing the float and installed for vertical displacement by means of articulated joint with rods coupled with pipe housing, and plates. Moreover, pump is furnished with radial spokes with stops hinge- connected with rods and outer surface of pipe housing under float. Plates are made in form of two leaves installed at right angle relative to each other and mounted on spokes by means of hinge joints located in place of corner joint of leaves for contact by inner surfaces with stops of spokes. Screw blades are fitted on lower parts of rods. Blades can be installed for rotation being mounted on adjacent rods with opposite hand of helix. Leaves are made with zero buoyancy. EFFECT: reduced expenses for lifting deep waters. 4 cl, 3 dwg
