The invention provides a ship cooling water system with a leakage alarm mechanism. The ship cooling water system comprises a low-temperature fresh water expansion tank, a high-level alarm liquid level switch, a low-level alarm liquid level switch, a liquid level meter, a liquid sight glass, a low-temperature cooling fresh water pump, a central cooler and cooled equipment. The high-level alarm liquid level switch, the low-level alarm liquid level switch and the liquid level meter are arranged in the low-temperature fresh water expansion tank; a water outlet and an overflow port of the low-temperature fresh water expansion tank are connected with a bilge water storage device through pipelines; the liquid sight glass is mounted on a pipeline connected with the overflow port; the height of the high-level alarm liquid level switch is lower than that of the overflow port; a water outlet of the low-temperature fresh water expansion tank sequentially cools the fresh water pump and the central cooler; the central cooler is connected with water inlets of all cooled devices, and water outlets of the cooled devices are connected with the low-temperature cooling fresh water pump. According to the ship cooling water system with the leakage alarm mechanism, the situation that a cooled medium leaks into cooling water in the cooling water system can be continuously monitored.
