The invention relates to the technical field of ship
fresh water anti-freezing, and discloses an anti-freezing mechanism of a ship
fresh water tank and a ship structure thereof.The anti-freezing mechanism comprises the
fresh water tank, and a water outlet pipeline is arranged at the bottom of the side wall of the fresh water tank; the fresh
water pressure pump is connected to the
tail end of the water outlet pipeline so as to receive fresh water of the fresh water tank, and the fresh
water pressure pump is connected with a water using mechanism; one end of the fresh water
backflow pipe is connected with the fresh
water pressure pump, and the other end of the fresh water
backflow pipe is connected with the top of the fresh water tank so that
backflow fresh water can drip on the surface of fresh water in the fresh water tank. According to the anti-freezing mode, anti-freezing is achieved through self-circulation of fresh water, heat source supply of a steam boiler or a hot oil boiler is not needed, hot oil,
compressed air and other media possibly containing oil or impurities do not need to be introduced, a drinking
water source is prevented from being polluted, complex equipment such as a hot oil and hot
water heater and an
electric heating coil does not need to be additionally arranged, and the modification cost and the maintenance difficulty are reduced.
