The invention relates to the field of inland navigation, and is intended to denote the dimensions of the fairway the fairway of the river.

Known hydropower plant converts the energy of flowing water into electricity, comprising floating means, the turbine and generator, located on the floating tool and providing consumers with electrical energy [1, 2].

The main drawback of these hydropower plants: no devices to stabilize them in the river, to the edge of the fairway, providing guaranteed dimensions of the fairway on this stretch of the waterway.

Also known river navigation buoy, at the request of France [3], which contains signal light from the light source, a stabilizer, a surface portion in the form of signal shapes, balancing the load. The disadvantage of this solution is the need for frequent maintenance of the light source is first buoy with built hydropower plant, containing a float with a stabilizer, motorsystem flap and fastener anchor chain in the underwater part of the buoy, a turbine coupled to a generator, enclosed in a waterproof camera, located on the float, the upper part in the form of sign with signal lamp with light source [4].

The disadvantages of this buoy vertical shaft of the hydropower plant are: low efficiency of energy use in river flow caused losses to overcome the flow resistance of the turbine blade that does not produce useful torque that overstates the requirements for developing a power generator, and the increase in inefficient power generator causes an increase in the effective area of the turbine blades to overcome the electromagnetic braking torque generator, reduces the efficiency and increases the intensity of the hydropower plant, and therefore, buoy, the decrease in stability caused by the location of the generator, and waterproof camera in a surface part of the buoy above the deck of the float, requiring additional measures to preserve the stability of the buoy in the stream, that also increases the intensity of the buoy.

River navigation buoy, the aqueous buoy.

The purpose of the invention: improved efficiency of the hydropower plant at the reduction of the material and the mass of the buoy.

This objective is achieved in that the float with a stabilizer, motorsystem flap and fastener anchor chain (burapa) in the underwater part of the buoy is made in the form of a catamaran, covers the perimeter of the bumper beam, with two lifting points along its longitudinal axis, equipped with folding cilium stabilizer with Schwerte, equipped with basic load balancing in its lower part, an additional load which is half the mass of the micro hydro, micro hydro with relevant generator and a device control signal source of light housed in a waterproof camera, which is the case for micro hydro, is part of the keel of the stabilizer and installed in deck hatch catamaran dimensions defined by the diameter of the cylindrical sign, is the lower half of the housing in the flow in contraction of the pressure chamber formed by an open confuser, increasing the speed of rotation of the turbines, mounted on two sides on the shaft of the generator which is the shaft of the micro and shifted by the angle of rotation otnositel is, the rich shaft generator micro hydro, which is also the shaft of the two turbines, is located horizontally across the stream, over its surface, providing a high efficiency of transmission of energy flow to the rotor of the generator micro hydro, through the interaction of the blades of the turbines with flow below the axis of rotation, and mouserotate the flap formed by the bow and stern keel stabilizer and is made in the form of a visor, connecting the underwater part of the keel of the stabilizer, with holes for fastening wirepa, with the front part of the deck of the float at a waterline of the buoy, passing below the peripheral cutting timber.

River navigation buoy with micro hydro for power of the signal light source is designed to float 1 catamaran base type, providing the installation on a specially provided seats sign right 2 or left 3 edges of the fairway of the same size. The float 1 is divided along the longitudinal axis of kelev the upward around the axis of its suspension 6 and is fixed by the stopper 7 in the inner pocket keel of the stabilizer 4, after which the buoy can be installed on any platform (including pipeline) in a vertical position, which provides the convenience store and manufacturability of operations in its manufacture, maintenance and repair. The balance weight 8 is attached to the bottom or side surfaces of Schwerte, depending on operating conditions. To prevent the buoy from damage caused by naval vessels, the perimeter of the float is equipped with a breaker bar 9, with two lifting eyebolts 10 along its longitudinal axis, as in the deck of the buoy 11 has a hole the size defined by the bore diameter of the cylindrical sign, and the slot 12 for installation and fixing of Schwerte 5 in the provision of repair and maintenance of the buoy. Part of the float includes a folding keel stabilizer 4 is equipped with basic load balancing 8, in the lower part of Schwerte 5, which is part of the keel of the stabilizer 4, additional weight which is the lower half of the mass of the micro, placed in the water chamber 13, which is the case of micro hydro, and part of the keel of the stabilizer 4. Micro hydro consisting of two turbines 14, the generator 15 to the control device of the source signal light is attached to the horizontal waterproof ora after fixing direction of the fastener tight-fitting collar housing micro hydro in folding Kileva the stabilizer 4, progibaetsa threaded mounting pairs 17, and then connects the two conductors 18, the signal light source 19 by twisting the wires according to the rules [5]. For convenience of Assembly and disassembly of the micro waterproof bulkhead 16 is equipped with eye-handle 20. To protect the blades of the turbines from debris floating on the surface of the water, there mouserotate the flap 21 in the shape of the visor, rolling in the stern of the float connecting the underwater part of the keel of the stabilizer 4, with holes 22 for attaching burapa 23, with the front part of the peripheral bumper beam 9. On deck 11 of the catamaran is set to sign 2 or 3, provided by the rules of navigation, distributed on the situation of the fairway for this section of the channel of the river.

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.
