SEA ICE BUOY Russian patent published in 2012 - IPC B63B22/16 F21S2/00 

FIELD: transport.

SUBSTANCE: invention relates to floating navigation means to be operated in ice conditions. Buoy streamlined tight body is divided by watertight bulkheads into compartments. LED-based optical hardware is located at buoy head part. Stabilising ballast is arranged at buoy tail part. Buoy tail compartment accommodates self-contained power supply composed of inertial power generator. The latter comprises capacitive molecular electric power accumulator(two-layer capacitor), charging device including DC generator with voltage generator relay with axle rigidly engaged with air turbine (for example, Wells turbine), turbine vaned wheel drive, cylindrical air chamber rigidly secured to tail section top bulkhead. Said air chamber houses inertial piston rigidly secured by spring dampers to air chamber top and bottom sections. Two air tubes are tightly jointed to chamber openings for compressed air passage from air chamber to turbine vaned wheel. In closed ice, power accumulator is charged by generator and/or windmill. Optical radiator is built around LED crystal integrated in modules to allow light transmission at frequencies of 460 to 633 newmen.

EFFECT: higher reliability, longer life, simplified operation.
