The utility model provides an ice beacon light winter, its characterized in that: including the navigation mark lamp, go up the flotation pontoon, lower flotation pontoon, the battery compartment, the connecting rod, the shaft, the flabellum, the navigation mark lamp lies in the upper surface center of flotation pontoon, the battery compartment top is connected in the below of navigation mark lamp, it is equipped with the cone to go up flotation pontoon outer wall waist position, the flabellum is connected in the epaxial component turbine of wheel, the navigation mark lamp includes the antenna, the modulator shell, the sealing washer, metal casing, the chassis, the modulator shell is located metal casing upper surface center, inside contains the modulator, be connected with metal casing through the sealing washer, the chassis is located metal casing's below, be connected metal casing with the chassis through being equipped with the bolt on the metal casing inclined plane, chassis welding is in come -up bobbin top portion. This device has reduced the modulator height, makes the probability of floating ice striking modulator reduce, and the cone can be effectively broken and prevented to ice the beacon light and is flooded by the ice -cube the ice around the flotation pontoon, and the electricity generation certainly of turbine can reduce the change frequency of battery, the service level of promotion navigation mark lamp.
