The proposed river navigation buoy with micro hydro for power of the signal light source operates as follows. The reduction of impacts of wind loads on the vertical position of the buoy roll is achieved by lowering the center of gravity of the buoy, by penetration of Schwerte and cargo weight attached to its lower part, as well as the placement of micro hydro units mainly in the underwater part of the buoy, with the float, emplace, made of plastic with stekloapparatura. Due to greater operational stability roll float catamaran base type requires balancing the load lighter weight in comparison with analogues and prototype. This design allows to reduce the overall weight of the buoy and weight of anchors required to hold the buoy in the river. The vertical position of the buoy on diferent is achieved by the difference between the lifting force of the front and rear sections of the hull of a catamaran, take into account the impact strength resistance of floats for the water, which is compensated by the reaction of burapa, adjusted for the rate of flow of the serviced site navigation, by fixing burapa in one of the holes of the stem. Stabilization of the buoy relative to the fixed edge of the fairway the fairway of the river is provided by balancing water flows, shared cilium stabilizer in the underwater part of the buoy into two equal components, equally affecting symmetric surfaces floats catamaran. The flow of water passing through the pressure chamber confuser, increases the speed and causes the rotation of the two turbines located in the narrowing of the confuser, providing higher efficiency on the shaft of generatorbundleinfo lighting equipment buoy throughout navigation. The turbine is protected from exposure to debris shield in the shape of the visor, smoothly discharge the upper part of the flow of garbage to mideling section of the buoy and stem guiding larger pritoplennye the debris in the lower layers of the flow relative to the stabilizer keel and hull of the catamaran. The slot 12 in the deck 11 of the buoy to install Schwerte 5 in the provision of repair and maintenance is at the same time and drain the water accumulated in the sign after flooding buoy.

SUBSTANCE: invention relates to radiolocation and radio navigation and may be used as a radar navigation marine buoy operating in decimetre and metre wavelength ranges. The radar marine buoy is a hollow metallic cone (HMC) with a right taper angle, the vertex of which faces the sea surface, which is the second reflective element, and a floating support, which is the HMC part at its vertex side. When the HMC is installed on the sea surface, with its vertex to the surface, an equivalent biconical radar reflector is formed, providing scattering indicatrix uniformity in the azimuthal plane. The HMC is open at the round base side and the whole its internal cavity is filled with a radio transparent material with a specific density 15...40 times lower than that of the sea water. The technical effect is the expansion of the marine buoy scattering indicatrix to 90° in the elevation plane and increase in its scattering cross-section (with a probability level of 0.5) to 4.3...14.2dB, in the wavelength range from decimetres to metres. The radio-transparent material prevents from the sea water ingress to the internal HMC cavity, also providing buoyancy and stability of the whole structure.
EFFECT: expansion of marine buoy scattering indicatrix and increase in its scattering cross-section.
