FIELD: hydraulic engineering, inlet of water from reservoirs and main canals for irrigation and utilization at industrial enterprises. SUBSTANCE: gear has source of compressed air ( compressor ) linked to main and additional perforated pipe-lines laid along perimeter of canal, baffle plate placed at angle with flow and attached with one end to feeding channel of water intake and with other end to berm of spillway nearest to pump-house. Perforations of pipe-lines are fitted with air exhaust valves and pipe-lines come in the form of individual links laid on bottom and slopes of canal at angle of 45-60 degrees with regard to water flow, anchored on bearing members and interconnected by means of flexible pipe-line with the use of pipe-unions. Perforated pipe-lines are connected to compressor through reversible tank fitted with pressure transducers of upper and lower limits of control over operation of compressor. Main perforated pipe-line is provided with high-pressure transducer and additional perforated pipe-line is fitted with low-pressure transducer which control elements are connected to perforated pipe- line at their ends. Pressure transducers are coupled to hydraulic drives interacting with actuators locates at starts of perforated pipe-lines. Spillway is coupled to rubbish collector. EFFECT: enhanced efficiency of clearing of water from rubbish and water plants thanks to automatization of process controlling air flame of gear. 4 dwg |
