The invention relates to power engineering and can be used for heating and power of individual consumers from alternative or renewable sources of mechanical energy - wind, solar, tidal, river, etc.,

Known solar-wind engine that converts energy from the sun and wind into mechanical work and containing the installed rotatably around the vertical axis of the double-walled exhaust pipe with spiral shaper gas flow and fixed on its outer side inclined blades, made in the form of sails /1/.

However, direct use of the mechanical energy of this engine to meet vital human needs is very difficult due to the large fluctuations of solar power and wind loads and the more urgent needs of humanity in thermal and electrical energy.

Closest to the technical essence of the present invention I have rtically shaft, on the lower end of which is fixed to the impeller placed in the tank with water and hydraulically connected with the turbine generator /2/.

A disadvantage of the known installation is the low intensity of energy exchange and large dimensions, which allows to use it only to provide the consumer with hot water, heated to 70oWith, and an auxiliary power supply when excessive wind load, when the hydraulic link is effective enough.

The technical task of the invention is to reduce the size of teplostroy, ensuring guaranteed heating Autonomous consumers, improving the efficiency of the heat transfer process, increasing the speed and temperature settings.

To solve this problem is proposed thermal water systems using alternative sources of mechanical energy, containing the drive motor with a vertical shaft, provided with a rotary transducer placed in the tank with liquid and connected with electromachine, characterized in that the shaft kinematically connected with a hydraulic pump and a ferromagnetic rotor small taper placed inside the tank overpressure, Saronikos, posted by with the ability to immerse the inlet pipe in the magnetic fluid. The side walls of the tank and rotor made in the form of mating with a gap surfaces, and on the surface of the rotor has a helical channels, and the side of the vessel wall is formed on the pole winding with a circular blind groove between the poles of the closed in a permanent magnet outside of the vessel. The tank is also provided with a pressure reducing-return valve for circulation of magnetic fluid in the specified mode between consumers (heating plate, heating etc) and water systems with the orifice of the discharge nozzle of the tank. In addition, the shaft kinematically connected with the rotor through an overrunning clutch with pulley belt transmission to the motor-generator connected to the said excitation winding and to the local electrical network. As a magnetic fluid is used proven lubricant-coolant oil-based fine with magnetic sludge.

The invention is illustrated by the drawing, which shows a schematic diagram and a longitudinal section of the proposed facility.

Thermal water systems comprises a drive verticallythe type, which is attached to the bottom of the vessel overpressure 4, built-in tank 5, is partially filled with ferrofluid 6 so that the inlet of the hydraulic pump 3 was always below the level of the magnetic fluid. The outlet of the pump communicates with the lower part of the volume chamber 4. On the form side walls of the vessel overpressure 4 and rotor 2 inside made in the form of mating with the clearance surfaces of the small taper. Vertical shifts of the rotor is easily adjustable gap. The side walls of the tank 4 is formed on the pole electric winding 7, closed by the permanent magnet 8 on the outside of the tank. Between the poles made a circular non-separating groove 9 for the purpose of transferring the magnetic lines of force on the ferromagnetic rotor and the gap between him and the magnetic core. PA surface of the ferromagnetic rotor 2 has a spiral channels 10 for the passage of the magnetic fluid.

Between the shaft 1 and the ferromagnetic rotor 2 is set overrunning clutch free wheel 11 with a pulley 12 and a belt 13 to the electric motor-generator 14, which is connected to the local grid 15 and the excitation winding 7 of a magnetic field.

Output tselem drain pipe of the tank 5, with food ring 17, with the radiator 18 and other users of the liquid coolant. The filling pipe of the tank 5 may be provided with an oil filter trap 20 for vapour deposition of magnetic fluid 6. As a magnetic fluid is used proven lubricant-coolant oil-based fine with magnetic sludge.

In native mode, the generation of heat and electricity, the proposed system works as follows. When the rotation shaft 1 starts to operate the hydraulic pump 3, forcing the magnetic fluid 6 from the bottom of the tank 5 into the vessel overpressure 4, where synchronously with the shaft 1 rotates a solid ferromagnetic rotor 2. Magnetic fluid 6 flows through the spiral channels 10 on the outer surface of the rotor and through the gap between the mating surfaces of the rotor and pole pieces separated non-circular groove 9. This groove provides a magnetic force lines of the permanent magnet 8 and the electrical coil 7 through the ferromagnetic rotor 2 and the corresponding gaps between it and the side wall of the vessel overpressure 4. By concentrating the magnetic field in the gap of the magnetic fluid 6 passes in pseudopolitical field. Due to viscous friction in the magnetic gap of the heat-carrier oil-based 6 is heated to 150-200oC. While working surfaces of the rotor 2 and the vessel wall 4 little wear because of friction exposed themselves to the particles of the ferromagnetic powder, suspended in a magnetic fluid 6, the dispersion and the quality of which in the process would only increase /4/. In natatorium space in the vessel 4, the viscosity of the liquid drops, and the hot coolant is available to consumers through the outlet of the tank 5 and the reducing-return valve 16, which stabilizes the pressure of the incoming magnetic fluid 6 at standard level 5-7 kg/cm2conventional heating systems hot water, but with a higher temperature. Moreover, relatively large ferromagnetic particles cannot overcome the magnetic field and to move beyond the vessel overpressure 4, whereas the fine particles of sludge in a balanced-original state, outside of this capacity is virtually no shrinkage. After passing and heating plates 17 for cooking, radiator 18 and inductor 19 chilled magnetic fluid 6 is returned to the tank 5, under atmosphereless 20, guarding the pair of magnetic fluid 6.

Simultaneously, the rotation of the shaft 1 through working overrunning clutch 11 to a pulley 12 and a belt 13 is transferred to the motor-generator 14, which nourishes the elektroobmotka 7 and the local grid 15 which can be connected to the buffer battery, charge current of the motor-generator 14, running the generator.

If there is no battery in the outlet 15, the voltage on the electrical coil 7 and the generated magnetic flux will be proportional to the speed of rotation of the pulley of the motor-generator 14 and the shaft 1 of a wind turbine, and therefore the force of viscous friction of the magnetic fluid 6 around the rotor 2 will be proportional to the wind, and hence the mechanical energy applied to the shaft 1, that is, there is an automatic and high efficiency of the process being controlled magneto-frictional conversion of mechanical energy into heat.

If the wind is not and the shaft 1 stops, the proposed installation will automatically switch to accept heat at which the motor 14 is fed from the buffer battery of the outlet 15, through a belt drive 13 and the pulley 12 directly to rotate the rotor 2, and will also be done by ntom efficiency, as thermal energy, mechanical energy is converted theoretically with 100% efficiency. While the overrunning clutch 11 eliminates wasteful leakage of the mechanical energy from the motor 14 to the non-working wind turbine, and the use of known converters AC / DC allows you to associate a local grid 15 several such units between themselves and household electricity 220 V of the unified energy system of the country.

Thus, the proposed installation provides: - the reduction of its dimensions and metal content: compared with the reference weight and dimensions of the prototype less; - the guaranteed heat Autonomous consumers high temperature coolant on cheap oil-based; - improving the efficiency of the process teleperedachi: a) through the use of the heat carrier from among the waste. Spent lubricating and cooling liquid, saturated ferromagnetic microparticles, which is troublesome waste Metalworking industry, in addition to saving electricity provides additional economic and environmental benefits; (b) the carrier has a higher heat capacity, enabling what is achieved in one pass of the liquid through the channels and gaps of the rotor, d) obtained the ability to control the conversion process.
