NON-FREEZING WATER AREA MAINTENANCE DEVICE Russian patent published in 2019 - IPC E02B15/00 E02B15/02 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to hydraulic engineering and can be used in operation in conditions of prolonged navigation of water areas adjacent to mooring embankments, slips, sluices and other transport facilities. Device for maintenance of water area in non-freezing condition includes pipeline 1, interconnected with heat carrier 9, which has combustion chamber, note here that simultaneously connected to pipeline 1 is large impeller 22 for supplying hot air under pressure to pipeline 2 with system of perforated pipelines 3 equipped with self-regulating mechanism. Operation of heat carrier 9 connected to a personal computer is monitored. Self-regulating mechanism includes vertical links of pipes, upper link of pipe has shape of ball, which view is made with confusor, with discharge nozzle oriented upwards. Other end of vertical pipe link is connected by flexible bellows with vertical link of pipe, which is connected to hole of perforated pipeline 3.

EFFECT: increased efficiency of heated air supply at operation in different temperature conditions of water area in non-freezing state.
