WATER LIFTING PUMP FOR MARINE SURF WAVE HYDRAULIC POWER PLANT Russian patent published in 2010 - IPC F03B13/12 

FIELD: engines and pumps.

SUBSTANCE: invention refers to marine hydraulic power engineering and can be used for construction of hydraulic power plant using the energy of breaking wave. Water lifting pump for marine surf wave hydraulic power plant includes pontoon-float 4 and hollow flattened cone 2 with lower wide intake and upper narrow supply part changing into vertical upward directed tube and which is rigidly connected to pontoon-float 4 with possibility of back-and-forth upward-downward movement under influence of breaking wave. Pump is equipped with the system of hollow flattened cones 2 with internal conicity of 0.025 to 0.01, which form common rigid construction and capacities 1 rigidly fixed and pre-filled with water, in each of which there lowered is movable cone 2 which is not connected rigidly to the housing of capacity 1 with possibility of water carry-over upward to the next adjacent above located capacity 1. In the first capacity 1 the upper edge is located at water level with possibility of being constantly filled with movement of breaking wave. Each of cones 1 is equipped with dividing check valve installed at the transition from cone 2 to the tube.

EFFECT: providing high operating efficiency.
