of the receiving chamber 4. The chamber 4 is provided with a chamber .12 for cleaning the mechanical impurities of the cooling zoda and the pipeline 13 with a bottom receiving chamber 14 with a receiving grid 15. The chamber 5 communicates with the dispensing chamber 16, which is divided by partitions 17 into compartments of uniform supply of outboard water to pumps 18 and 19. Pumps 18 and 19 are connected to heat exchangers 20 and to lines 21 and 22 to discharge heated water, which are connected to chamber 8 heated in heat exchangers. On the hot line: water placed control valves 23.

The system works as follows.

Outboard water through the receiving grates 2 and 15 comes along with. ice, snow and sludge, and when working in shallow water and with mechanical impurities (sand, silt, pebbles) into the bottom receiving chamber 14 and into the onboard receiving chamber 1. Out of the bottom receiving chamber, outboard water through pipe 13 and chamber 12 enters the onboard receiving chamber 1, where it mixes with the water received through the onboard receiving grids, rises and bends around the wall 3. Here the ice and air are directed to the collection pit 6, from where air is vented to the atmosphere, and the floating ice is melted with heated water from chamber 8. Arrival of heated water from the kame s 8 through line 10 and manifold 11 in the lower receiving chastp onboard camera spins osedayuschies flow and mechanical impurities when rounding flow baffle shield are washed overboard. When the ice receiving lattices fit snugly with ice, the water level in the ice ditch falls and the water that is drunk from collector 11 is heated, because of the temperature difference in the ice rises and washes the receiving lattice, melting the ice and cleaning the receiving lattice, ensuring reliable water intake through side receiving grids. Cleared of mechanical impurities, the water enters the mixing chamber 5, where it mixes with the heated water coming from chamber 8 and enters the dispensing chamber 16 in the near-ductal space.

The extension of the water path to the pumps located near the side receiving chambers allows all the ice that has passed through the receiving and mixing chambers to be melted and the remaining mechanical impurities in the outboard water to be separated in the bottom set of the vessel. From the dispensing chamber 16 through pumps 18 and 19, water is supplied for cooling to the heat exchangers of the main and main consumers of ship engines, as well as to other consumers. The flow of heated water from the heat exchangers to the system for melting ice and heating the outboard water or discharging it Overboard depends on the amount of ice, snow and sludge in the seawater and is automatically regulated, for which the power and energy installation and temperature sensors are installed. Temperature sensors are installed in an ice drain at the inlet of the water flow into the dispensing chamber. The signals from the temperature and power sensors are supplied to control regulating valves installed in the heated water supply line 21 from the heat exchangers to the chamber 8 or to the line 22 dumping it overboard. Control valves 23 provide the necessary flow of water through pipelines and chambers for both sufficient melting of ice and removal of mechanical mixtures from overboard water overboard.
