The invention relates to a power system and can be used for heating and hot water separate cottages, garden houses, greenhouses and other similar objects.

Known wind turbine for heating of premises, containing a sealed housing with compressed air and coaxially mounted in a vertical turbine shaft with an auger, which mixes the compressed air and heats the sealed enclosure inside the heated space [1].

The disadvantages of this wind turbine are the low efficiency of heating the compressed air and the inconvenience of installation of the sealed enclosure inside the heated space.

Known also veritablement containing water storage tank, windmill, bevel gear transmission (transmission), mechanical heater in mixers with moving blades, each pair of which is made for the centrifugal regulator watt and rotates in different directions [2].

Despite the increase in the relative speed of the opposite rotation of the stirring blades in the working fluid and the presence of accelerating the transmission multiplier efficiency and the heating rate for water supply are insufficient for practical use of such devices with the low-speed wind turbines in Russia, where the average the wind speed is only 5 m/s.

The technical task of the present invention is to increase the efficiency of the proposed setrotationangle and improving coordination tageskarte characteristics of a wind turbine with load characteristics accelerating transmission and agitator of the working fluid.

Applying setrotationangle for heating of premises containing the turbine, generator, storage tank, and accelerating the transmission with a stirrer viscous working fluid, characterized in that in the first embodiment of setrotationangle vertical shaft of its wind turbine with screw mixer of the working fluid in the form of a suspension of heavy solid particles and viscous fluid accommodated in the Central circulation pipe, provided with side Windows and installed with axial and radial clearances within a thermally insulated enclosure, equipped with sealed bearings rotation and jacket water coolant directly connected to the contour of the radiator, a hydraulic accumulator, a distribution valve and circulation pump, kinematically connected to the shaft of a wind turbine. When the top cover is insulated housing provided with a centering plates circulating pipe, the lower part of which there is a ring fence for a similar centering plates the lower part of thermally insulated housing is a, providing end-to-end gaps around the circulation pipe with the annular stop and this frame is not less than the diameter of the circulation pipe.

The second option States setrotationangle for heating of premises containing the turbine, generator, storage tank, and accelerating the transmission with a stirrer viscous working fluid, characterized in that the turbine shaft is connected with the horizontal shaft of the drum mixer of the working fluid in the form of a suspension of heavy solid particles and viscous fluid is placed inside a thermally insulated enclosure, equipped with sealed bearings rotation and jacket water coolant directly connected to the contour of the radiator, a hydraulic accumulator, a distribution valve and circulation pump, kinematically connected to the shaft of a wind turbine. When this drum agitators working body has an internal longitudinal ribs and installed on two svobodnoradikal rollers, over which made the input and output holes of the water jacket insulated housing.

The invention is illustrated by drawings, where figure 1 shows a longitudinal section and a functional diagram of a screw options setrotationangle, and figure 2 is a similar diagram and cross section of its drum option.

We offer setrotationangle in the first embodiment, Figure 1 contains, like the prototype, the heat source, the heat accumulator and accelerating the transmission of a wind turbine, which has a vertical shaft 1 is structurally enters the auger 2 agitators working body 3 in the form of a suspension of heavy solid particles and viscous fluid, located in the Central circulation pipe 4, provided with side Windows 5. This pipe is installed coaxially with the radial and axial clearances within a thermally insulated housing 6, is equipped with sealed bearings rotation 7 and the conical jacket water coolant 8 directly connected to the contour of the radiator 9, the hydraulic accumulator 10, a distribution valve 11 and the circulation pump 12, for example gear, which is kinematically connected with the shaft of a wind turbine 1.

When the top cover is insulated housing 6 provided with a centering plates 13 of the circulation pipe 4, the lower part of which has an annular stop 14 for a similar centering plates 15 of the lower part of thermally insulated housing 6, which provides end-to-end gaps around the circulation pipe with the annular stop and this frame is not less than the diameter of the circulation pipe 4. As a heavy solid particles of the suspension of the working body 3 can take iron shot, which is commonly used in the blasting apparatus is itih details and as a binder liquid - viscous mineral gear oil or silicone fluid in proportions providing a pasty consistency of the working body 3 like a cement mortar.

Setrotationangle according to the second variant, Figure 2, contains the same functional units: turbine, generator, storage tank, and accelerating the transmission with a stirrer viscous working fluid. Turbine shaft (not shown) connected with the horizontal shaft 16 of the drum mixer 17 of the working fluid 18 in the form of a suspension of heavy solids and viscous liquids.

The drum 17 is placed inside a thermally insulated housing 19, is equipped with sealed bearings rotation 20 and the jacket water coolant 21, directly connected to the contour of the radiator 22, the hydraulic accumulator 23, the distribution valve 24 and the circulation pump 25, kinematically connected to the shaft of a wind turbine.

While the drum of the mixer 17 of the working fluid can be provided with internal longitudinal ribs 26 and is mounted on two svobodnoradikal rollers 27 on which is made the input 28 and output holes 29 of the water jacket insulated housing. In this case, the circulation pump may be missing, because its functions are performed by the outer surface of the drum mesh is key with the rollers, which due to the wetting of their surfaces distilled water coolant from the inlet to the outlet of the water jacket.

Setrotationangle presented in figure 1, works as follows. At relatively slow rotation of a vertical shaft wind turbine 1 in a hermetically sealed bearings 7 together with him is rotated and the screw 2, which captures the working body 3 in the lower conical part of the jacket water coolant 8 and slowly lifts it up by the circulation pipe 4 to the lower level of the side window 5. Thanks pasty consistency of heavy and viscous working his body clots fall through the side window 5 and under free fall acceleration of the gravitational field of the earth gain vertical speed, which is far superior to the tangential velocity of rotation of the screw 2, which, together with the circulation pipe 4 and performs the function of accelerating the transmission. Moreover, the maximum falling speed of the working fluid and the braking torque this screw is proportional to the lifting height of the working body 3 inside the circulation pipe 4.

The decrease in working body 3 is absolutely elastic collision, almost completely converts the kinetic energy of motion of the working fluid in the heat, which through the metal wall of the conical jacket piped water tepano is Italy 8 inside the heat-insulated housing 6.

Therefore, inelastic impact and viscous friction of the working fluid are generators of heat, and a water jacket coolant performs the function of storage tank, directly transfers heat to the radiator 9 under the influence of the circulation pump 12, which pumps water coolant around the contour of the installation, including through the distribution valve 11 required to fill and drain, and a hydraulic accumulator 10, where the process water coolant.

By increasing the speed of rotation of the turbine shaft 1 significant propellant mass 3 manages to rise to the upper end of the circulation pipe 4 and fall down through the gaps between the centering plates 13 and 15 with a much greater height and a greater amount of kinetic energy to impinge on the working body, which is in the lower conical part of the installation. This is accompanied by a significant increase in braking torque on the turbine shaft 1, i.e. the automatic coordination of load characteristics such accelerating transmission with the current capacity of a wind turbine without any regulatory elements.

At the same time increases the speed of pumping water coolant through the radiator heating 8, since the circulation pump 12 is supplied kinematic drive on the same shaft of a wind turbine 1.

Setrotationangle presented in figure 2, works in a similar way, only the rotation of the turbine shaft (not shown) is transmitted to the horizontal shaft 16 of the drum mixer 17 of the working fluid 18, the longitudinal blades 26 which picks up part of the working fluid 18 to a certain height and provide them fall mainly on a parabolic trajectory [3].

As a result, not elastic drop and viscous friction of the working fluid 15 is his warm-up followed by transfer of heat through the walls of the drum mixer 17 the jacket water coolant 21, circulating along the contour of the radiator 22, which may be located at a considerable distance from setrotationangle. This circulation can occur not only under the action of the circulation pump 25, but directly due to wetting and transfer water cooled surface of the drum mixer 17 is mounted with a small gap on the longitudinal rollers 27, which prevent the reverse transfer of fluid from the outlet 29 in the heat-insulated housing 19 to its input port 28.

Due to this being implemented at the same time several important functions - circulation pump, Overdrive transmission, boiler and storage tank into one unit, thermal capacity of which is N prop is ntionally the following value: /3/

N=0,39Rm3gw/η[KInt](1)

Where: R is the radius of the drum mixer,

g - acceleration of gravity=9.8 m/s2,

w - angular velocity of rotation of the drum,

η - efficiency mechanical drive,

m3download the working fluid tons, which at the same length and the diameter of the drum is equal to

m3=2πR3ρμ.(2)

Here: ρ is the density of the working fluid tons/m3,

µ - coefficient of filling of the drum body work.

Since the optimum speed of rotation of the drum, in which there is a separation of the working of the body and its movement along the parabola, also depends on the radius R,

w=(g/R)12[pandd/ eK](3)

The total capacity of this installation follows the power law 7/2

N=0.8πρμg3/2wR7/2/η(4)

and much depends on the linear scale of the structure.

Therefore, in practice, the proposed setrotationangle it is advisable to produce power in the tens of kW or more, because only at these dimensions it will be commensurate with the size of the turbine and will provide significant long-term accumulation of thermal energy.
