<p>PURPOSE:To achieve large water lifting circulation power with small volume of air consumption by dispersingly disposing a plurality of intermittent air water lifting cylinders at substantial distance intervals. CONSTITUTION:A plurality of intermittent air water lifting cylinders 1A and 1B are dispersingly disposed at substantial distance intervals on a water bottom of a water area such as a waterstorage pond or the like. A unified air feeding device 2 is provided in a central position close to both of air water lifting cylinders 1A and 1B in average. A closed air receiving chamber 4 and a plural ity of air feeding chambers 6A and 6B are provided in said unified air feeding device 2 and compressed air is concentratedly fed from the upper side of the pond to said air receiving chamber 4. Then, said compressed air is disposed to respective air feeding chamber 6A and 6B through orifices (7A...) (7B...) provided in the positions of respectively equal height of multi-stages up to down. After that, the air is transferred to air storages of respective intermittent air water lifting cylinders 1A and 1B through respective air feeding chambers 6A and 6B connected with said cylinders. As a result, large water circulation capability is achieved with small air consumption.</p> |
