LOW-PRESSURE DRIP IRRIGATION WATERING SYSTEM

摘要

FIELD: pipelines.;SUBSTANCE: low-pressure system for irrigation of slope lands includes distribution pipeline, to which through pressure regulator are connected irrigation pipelines with control pipes of different length, made in form of droppers of elastoplastic elements. Inner cavity of branch pipes is equipped with tubular porous element. Adjustable branch pipes are arranged on external surface of irrigation pipes and cover drilled outlets in tube. At some distance with a gap from the free end of the droppers a reflector-screen is coaxially fixed in the form of a resilient plastic fixing plate with bent edges along the circumference towards the water outlet from the dropper end. Inserted tubular porous elements are made with possibility of water flow motion braking and provision of water outlet at dropper drop end. Irrigation pipelines are suspended with possibility of movement in horizontal plane between posts with a positive slope. Head section of each irrigation pipeline is equipped with a reduction gear, a pressure gauge, a standard plastic filter with a cylindrical grid and a counter. Counter is made in the form of water flow measurement unit. Distributing pipeline is additionally equipped with controller with possibility of water flow rate, duration and irrigation intervals programming and is connected via communication line with personal computer.;EFFECT: invention provides uniformity of falling drops with the help of a reflector-screen towards plants planting on terraces in conditions of positive inclination of irrigation tubes and taking into account the drops relative to the ground surface.;5 cl, 5 dwg
