NAVIGATION BUOY Russian patent published in 2019 - IPC B63B22/16 

FIELD: buoys and sea marks.

SUBSTANCE: invention relates to floating navigation aids, namely buoys. Navigation buoy contains a sealed enclosure that is divided by watertight bulkheads into compartments, light-optical equipment with LEDs and a stabilizing ballast. In the internal cavity of the housing, a container is installed inside which the guide is fixed and the rod is located with the possibility of movement relative to the guide. Rotor with permanent magnets of an electric generator is mounted on the rod. Stator of the electric generator is fixed on the inner surface of the tank. Stator winding of the generator is connected to the input of the charger, and the output of the charger is connected to the battery from which the light-optical equipment is powered. Tank is made in the form of a truncated cone, the internal cavity of the body is filled with liquid to the level of the waterline of the navigation buoy with a viscosity greater than that of water. L-shaped grip encompassing the guide and a rotor with permanent magnets is attached to the upper end of the rod, and a ball pin of the ball joint, the body of which is rigidly fixed on the floating platform, is attached to the lower end. Stator winding is made distributed along the lateral surface of the container and is located in the slots of the guide circular motion.

EFFECT: reliability of the navigation buoy is improved.
