The anti-icing sea chest device comprises a water inlet grating, a baffle, a sealing cover, a filtering grating, a cooling water reinjection pipe and a sea water pump suction pipe, the sea chest is divided into an ice collecting area on the upper portion, a water inlet area and a filtering area on the middle portion and a water drainage area on the lower portion, and the water inlet area and the filtering area are separated left and right through the baffle. The side, facing the water inlet area, of the bottom of the baffle is connected with the sealing cover, the water inlet area and the water drainage area are vertically separated through the sealing cover, the filtering grid is arranged between the filtering area and the water drainage area, a water inlet grid is arranged on a ship body outer plate of the water inlet area, and a water outlet grid is arranged on a ship body outer plate of the water drainage area. An inlet of the seawater pump suction pipe is connected with the drainage area, and an outlet of the cooling water reinjection pipe is connected with the ice collection area. The sea chest device can effectively remove floating ice at an inlet of a sea water pump, a pipeline system in a ship body is prevented from being blocked, and sailing safety is guaranteed.
