SPRINKLER SYSTEM Russian patent published in 1995 - IPC

FIELD: mechanical engineering; sprinkler installations. SUBSTANCE: this sprinkler system incorporates rectangular grate truss at whose corners are disposed electrically driven aerodynamic screws. Located below rectangular truss are sprinkler water discharge outlets communicating with pump unit via flexible hose and water receiver pipe. Turning on aerodynamic screw electric drive gives rise to lift force which raises rectangular truss to desired height, cause aerodynamic control surfaces to bring rectangular truss to desired position over field to be sprinkled and energize pumps. EFFECT: truss-type design of sprinkler having water conveying belt, location of aerodynamic screws under truss corner, regulation of screw revolution plane and separate reeling of cable and hose allow expanding range of capabilities of sprinkler system, that is, variation of height, location and sprinkling area. 2 cl, 5 dwg
