DESCRIPTION OF THE INVENTION

The invention relates to a device energosozdayuschemu, namely teplovetrodvigatelyu that uses the difference in temperature regimes, creating a constant air flow of the rising type and vetronagruzku to generate clean energy.

Known carousel wind turbine (see. Russian patent 1787209. Carousel windmill. IPC F 03 D 3/00. Bul. 1, 1993), comprising a vertical shaft and radial blades made of polymer composite material with oriented fibers.

The downside is the frequency of operation, which is determined by the presence of wind load.

Known wind turbine tower (see. Russian patent 2038511. wind turbine tower. IPC F 03 D 3/04. Bull. 18, 1995), comprising a tower placed on the roof of the building with attic and performed as a convergent channel with vertical input channels equipped with regulating shutters, wind wheel, connecting coaxially installed inside the exhaust pipe vertical shaft to a generator, a deflector with windows and weathervane, kinematically connected with doors and mesh fencing installed on the windows.

The disadvantage is the high energemkost maintain the stability of the wind turbine, due to the need to override a stagnant zone at the inlet to the exhaust pipe, which requires the use of extreme temperatures rising air currents inside the attic and ambient building air quality.

An object of the invention is to improve the efficiency and reduce the energy intensity of the stable development of clean energy process by eliminating the stagnant position of the rising air flow type, by providing additional air draft in the chimney when you create a vacuum in its upper opening. In addition, an additional heating of the solar energy air entering the lower opening the exhaust pipe, reduces the density of the upstream, thus increasing the velocity head in the wind wheel that raises to a higher level the process of energy production.

The technical result is achieved by the fact that the tower wind turbine comprising a tower placed on the roof of the building with attic and performed as a vertical convergent channel with input channels equipped with regulating valves, wind wheel, connected coaxially installed inside the exhaust pipe vertical shaft to a generator, a deflector with windows and weathervane, kinematically connected with the regulatory doors and mesh fencing installed on the windows, provided with curved planes of the guide and fasten the edges connecting konfuzor with chimney. Confusers on the outer surface is covered with a shielding film, and on the inner surface has a curved groove, longitudinally extending from the larger convergent channel inlet section to a smaller cross-section of its output.

Wind turbine towers

FIG. 1 is a schematic diagram of a tower of a wind turbine, FIG. 2 - scan the inner surface convergent channel as part of the tower of a wind turbine in Figure 1.

Wind turbine comprising a tower placed on the roof of the building 1, which has an attic space 2, and is designed as a vertical convergent channel 3 to 4 input channels, provided with regulating valves 5. Wind wheel 6, located in the deflector 7, is connected coaxially installed inside the exhaust pipe 8 vertical shaft 9 with the generator 10. On the deflector vane 6 is 11, kinematically connected with the regulatory doors and mesh fencing windows. Confusers 3 by curved planes 12 with the guide and fasten the ribs 13 connected to the exhaust pipe 8. The outer surface of the convergent channel 3 is covered with a shielding film 14. On the inner surface of the convergent channel 3 are curved grooves 15, arranged longitudinally from the larger inlet section 16 convergent channel 3 output to a smaller cross-section 17.

Wind turbine towers WORKS AS FOLLOWS

The building 1 (residential building, industrial plant hot production or selhozstroenie eg farm), which has a warm attic space 2 is constantly observed the movement of the rising air flow emitted by the deflector 7 to the environment, with the establishment at the outlet chimney 8 zones venting located in the interior of convergent channel 3. However, for the implementation of a wind turbine requires a certain dynamic pressure, which provides the rotational motion of the wind wheel 6. As a result of the fact that the air environment surrounding konfuzor 3 has a temperature lower and respectively higher density than air from warm attic on the exhaust pipe 8 into the deflector 7, there is a driving force (as the difference between the ambient air density of the medium and exhaust air attic), providing acceleration of the air flow in the internal volume of convergent channel 3 followed by the formation here rarefied zone, resulting in the opening of regulating valves 5.

The outside air entering the confusor 3 under the combined action of suction and the driving power flowing around the upper and lower curved plane 12, but also guides and swirl edge 13 is twisted, creating ejection effect due to increased air velocity in the duct between the curved plane 12 and the outer surface exhaust pipe 8. The curved grooves 15 supports (does not go to the jet, laminar) airflow swirls, movement, eliminating the formation of stagnant zones - the laminar sublayer, dramatically reducing the velocity near the inner surface of the convergent channel 3, from its larger inlet 16 to smaller outlet 17. As a result of the combined action of the upstream moving in chimney 8, and swirling air internal volume convergent channel 3 is carried out the rotary motion of the wind wheel (wind turbines) 6, connected by a vertical shaft 9 with 10 generator.

In the presence of solar radiation (sunshine) shielding film 14 carries out an intense heat transfer body convergent channel 3, which improves the process of acceleration of the rising of the outer air flow along the building 1, and by heating the boundary layer of the internal air, intensifies its spin when moving on curved grooves 15 of the more holes 16 to a smaller opening 17 convergent channel 3. heated-air boundary layer, having a lower density starts at a higher rate to rise to 6 wind wheel, dragging along the main stream of air flowing through konfuzor 3 in the deflector 7, and, as a consequence, there has been increase energy production generator 10, i.e. wind turbine tower as it shifts to a higher level of production of clean energy.

At wind load in any direction vane 11 is set to the appropriate position, by acting kinetically on the sash window regulators deflector 7, and the open regulating valve 5 (for example, in accordance with the direction of the arrows in Figure 1) admit outside air into the outer air confusor 3 under the action wind pressure, by moving the upper and lower curved planes 12 a and along the guide ribs 13 and the swirl and contacting the curved grooves twists and affects the wind wheel 6, and then through the vent window 7 is released into the environment. As a result, the wind turbine tower goes to a higher level of energy production.

An advantage of the invention is that the device provides increased reliability and production of clean energy at any time regardless of the season by increasing exergy sensitivity threshold (see., E.g., page 115, Technical Nashchokin VV thermodynamics and heat transfer. M ., 1980, 469 pp.), i.e. performance permanent air currents rising type, by eliminating the stagnant air situation, entering through the chimney from the attic to the wind wheel. The value of Exergy, which provides effective work of the tower of a wind turbine in a constant loop operation, has the opportunity to move to a higher level depending on the climatic conditions of operation of residential and industrial buildings with a warm attic by additional acceleration under the influence of solar radiation and / or wind load , the airflow acting on the wind wheel.
