DESCRIPTION OF THE INVENTION

The invention relates to wind energy converters to air flow energy into a rotational movement windmill.

Known rotor of wind [1], comprising a vertical support tube, the upper and lower belt with grooves in the side walls form curved along the arc sectors arranged vertically.

Prototype converts the horizontal wind flow into a rotary motion, but does not allow to use the energy thus upward flow and, therefore, is not operational in the absence or very low value of the horizontal wind flow.

The purpose of the invention - provision of health of wind and / or air flow rising in any combination thereof and increasing energy output.

The goal is achieved by the wind turbine, comprising a vertical support tube, connected to drive an energy axis movable attachment point fixed to the support tube top and bottom belt, between which are placed curved in an arc sectors, is equipped with a pipe-duct, the lower zone is adjacent to the gap to -duct tube, is designed as a spoked wheel and is provided with inclined vanes on the number of sectors, sectors arranged along a helix inclined in relation to the support tube, and a connection axis with a drive energy source is made on top of the support tube. Further, the diameter d of the lower belt wheel ratio is selected from d = D- (0,5 ÷ 0,9) H, where D - diameter of the upper zone, H - distance between the belts, the diameter of the hole-duct pipe equal to the outer diameter of the lower belt, lower belt blade mounted movably on the needles to move with respect to the horizontal plane from 10 ° to 80 °, the outer ends of the sectors outside the circle zones are formed radius r = (0,4 ÷ 0,5) D.

The structure of the windmill shown in Figure 1 is a perspective view, Figure 2 shows a front view with a cut-riser duct.

The vertical carrier tube 1 with an axis 2 for connection with an electric generator are rigidly fixed an upper continuous belt 3 and the lower belt 4 in the form of a spoked wheel. Between the zones 3 and 4 are arranged obliquely bent along a helical line along the arc sectors 5. At the lower belt 4 inclined blades 6 are fixed by the number of sectors 5. windmill rotates freely in bearings 7 and 8, which by means of arms 9 and 10 are attached to the wind turbine support structure (not shown). The lower zone 4 adjoins a small gap-duct pipe 11 rising air flow V B. The diameter of the tube 11 in its upper part to the diameter of wheel 4, the lower belt.

At considerable length of pipe 11, it creates sufficient to rotate the windmill upward air flow even in the absence of the horizontal wind flow. Upstream influences through the vanes 6 on 5 sectors, creating a torque in the movable part of the wind turbine.

In the presence of a horizontal air flow (wind) V n torque significantly increases due to the cumulative effects of both streams. The result is a rotation of the wind turbine when the wind increases and the absence of torque, while the impact of the wind and the rising air stream.

Two variants of fastening the spokes to the blades 6 of the lower belt 4. In the first embodiment, blade 6 rigidly fixed at 30 ÷ 60 ° to the horizontal plane. Air flows in V n and V are reflected from the surfaces of the blades 5, 6 sectors, resulting wind turbine to rotate. In the second embodiment, to freely rotate blade spokes between 10 ° and 80 ° to the horizontal plane. The angular position of the blades 6 in this case will depend on the velocity V and the ratio of air flow velocities and V n. In a second embodiment of fastening the blades 6 substantially reduces their inhibitory action when large differences of wind velocity.

Rated torque wind turbine depends on the wheel diameter upper and lower belts 3 and 4, the distance between the belts of the sectors 5 and 6 the angle of inclination of the blades, and the velocities of the rising air currents and horizontal.

As the pipe-duct 11 may be used smoke and flue pipe of thermal power plants, boiler plants, industrial facilities, ventilation pipes of multi-storey buildings.

The proposed wind turbine can be used as the basis for the power plant from the centralized nonvolatile gazoelektrosnabzheniya buildings. In this case, the duct pipe can simultaneously perform the function of the ventilation or vapor pipe collection from all rooms of the building.

In order to ensure maximum utilization of the energy of the rising and horizontal wind flows should comply with the following aspect ratio wind turbine:

d = D- (0,5 ÷ 0,9) H,

where d - diameter of the wheels of the lower zone 4,

D - diameter of the upper belt 3,

H - distance between zones 3 and 4.

d a = d, where d a - pipe-diameter hole 11 of the duct.

r = (0,4 ÷ 0,5) D, where r - the radius of the arc of the outer ends of the sectors outside the circle of zones 3 and 4.
