The anti-icing sea chest device comprises a seawater tank, a water inlet grating, a cooling water reinjection pipe, a seawater pump suction pipe and a baffle, the seawater tank is divided into an ice collection area on the upper portion and a water inlet area and a water drainage area on the lower portion, and the baffle is fixedly arranged in the seawater tank. The baffle is used for separating a water inlet area and a water outlet area of the seawater tank, the water inlet grating is arranged on a ship body outer plate of the seawater tank water inlet area, an inlet of the seawater pump suction pipe is connected with the seawater tank water outlet area, and an outlet of the cooling water reinjection pipe is connected with the seawater tank ice collecting area. The sea chest device is simple in structure, floating ice at an inlet of a sea water pump can be effectively removed, and a pipeline system in a ship body is prevented from being blocked.
