DESCRIPTION OF THE INVENTION
The invention relates to wind power, namely to environmentally friendly wind power plants with a closed cycle of air flow.
A wind turbine is known, comprising a rotor arranged in the form of shafts arranged one in the other and two tiers of blades, a generator, and in the upper part of the tower the apparatus is provided with two cones installed coaxially from the two ends of the tiers of the blades and facing vertices one to the other , The socket-concentrator, the partition between the tiers and the fixed outer ring of the guide vanes (see RU 2028504 C1, F 03 D 3/02, 09.02.1995).
The shortcomings of the installation include low efficiency of wind energy use, complexity of construction in the presence of a high tower, which increases the capital costs for maintenance of the installation.
A wind power plant is known, containing blades fixed on an endless belt, enclosing pulleys mounted on shafts and connected to a swivel frame, a windshield, a generator, an ejector with a pipeline and wind chimneys (see SU 1523710 A, class F 03 D 5/02 , 11/23/1989).
The disadvantages of the installation include the complexity of the high-rise structure, low reliability at high wind speed, susceptibility to rollover.
A wind turbine is known, comprising a tower, a wind motor with a vertical axis of rotation, a generator and ejector systems consisting of guide funnels connected to the inner cavity of the tower and directed to the blades of the windmill (see RU 2105189 C1, cl. F 03 D 3/00, 20.02.1998), on the basis of the essential features of the invention adopted for the prototype.
The shortcomings of the installation include an open version, the presence of electric motors for forced ejection of the air flow, a counter-rotor drive of rotation, irrational use of scarce arable land.
The technical result, which consists in increasing the reliability of the wind farm and increasing the coefficient of the use of wind force, is achieved due to the fact that in a wind turbine containing a tower, a windmill with a vertical axis of rotation, a generator and ejector systems consisting of guide funnels connected to the inner cavity of the tower and The windmill is made of a single-stage winding engine, rotating from two wind currents, the first is fed through cones at the top of the tower, and the second one is fed through ejectors made in vertical, while the wind installation contains external and internal air accumulators, the second and third Generators, a computer room and a mine, with the first and second generators placed in the tower and connected to the windmill by means of a high-speed electromagnetic reducer, and the third generator connected to the drive through the electromagnetic clutch of the clutch, the start of the first and second generators occurs through the reducer, and the third through Electromagnetic clutch.
The windmill is put on the generator stator with a gap, the generator drive is located inside, and the ejectors and air accumulator are outside the tower.
This set of essential features of the invention makes it possible to construct a qualitatively new windmill - a forestry, which can be installed, for example, along the railway line, at a distance of not more than 200 m from each other. For the construction of such windmills, it is necessary to erect artificial burial mounds, whose height can be from 100 to 300 m, with an endurance for sealing up to two years.

In Fig. 1 is a general view of the wind turbine; | |

The wind turbine comprises a tower 1 of a conical shape, a wind motor 2 with a vertical axis of rotation, a first generator 3 and ejector systems 4 consisting of guide funnels 5 connected to the internal cavity 6 of the tower 1 and directed to the blades 7 of the windmill engine 2, Single-stage and receiving two flows, the first flows through the cones 8 and 9 installed coaxially in the upper part 10 of the tower 1 and the second through the ejector systems 4 made in vertical, the installation comprising an external (not shown) and internal 11 air accumulators, a second And a third generator 12,13, a computer room 14 in which the third generator 13 is located and a shaft 15, the first generator 3 and the second generator 12 being located in the tower 1 and connected to the wind motor 2 by means of a high-speed electromagnetic gear 16 (three-speed) And the third generator 13 is connected to the drive via the electromagnetic clutch 17, the start of the first and second generators 3, 12 occurs through the reduction gear 16 and the third generator 13 via the electromagnetic clutch 17 at low speed. |
The wind turbine 2 in the lower part is put on the fixed stator of the generator 3 with gaps and rests on the annular rail track with the trolleys 18 and in the upper part is freely set on the shaft 19. The generators 3 and 12 and have the rotors 20 and 21 connected by the vertical shaft 19 to each other Another through a mechanical coupling 22.
On the outside of Tower 1, vertical ejector systems 4 are installed, of which there may be at least six pieces on each side.
Between the cones 8 and 9, stationary blades are fixed along the circumference: guides 23 deployed to supply air flow to a certain angle with respect to the wind turbine 2, and the airflow concentrators 24 (in an amount of 6 to 8 pieces).
The building of the computer room 14 serves as the foundation for the installation 25, and the roof of the computer room 14 has the form of a cone and is a screen for the ejector systems 4 (see Figure 3).
The ejector systems 4 create an overpressure in the upper tapered position of the tower 1 and the reflector 26, so that the airflow through the outlets 27 (Figure 2) enters the lower part of the shaft 15 where it spreads through the two lower funnels 5 of each ejector in the system 4 with the bell 28 communicating with the shaft 15. Two flows - one external, the other internal - are separated by a partition 29, and then in the upper part of the partition 29 are reconnected.
The funnels 5 of the ejector systems 4 are embedded in the wall of the shaft 15 (Figures 2 and 3) at an angle. The shaft 30 and the electromagnetic clutch 17 accelerate the third generator 13. The shaft 15 of the second generator 12 is semi-hermetic, and the shaft 31 (Figure 2) is for the third generator 13. The tower 1 in the middle part has a connection 32 in case of transportation to the place of installation or repair, And the concentrators 24 have windows 33 for lines.
The installation works as follows. With wind force greater than 3 m / s, airflow through cones 8 and 9 and fixed vanes-guides 23 falls on the blades 7 of windmill engine 2 and drives them into rotation. The wind engine 2 is connected via a high-speed electromagnetic reducer 16 with generators 3 and 12, where the mechanical energy of the air flow is converted into electrical, then a third generator 13 is triggered smoothly to the fourth operating speed, coupled to the first two through the electromagnetic clutch 17, Through executive devices to the consumer. Through the ejector vertical systems 4, the airflow can enter the rotor 7 of the windmill engine 2, drive them into rotation and activate the drive consisting of three generators 3, 12, 13, a reducer 16 and a clutch 17, due to the excess Of the pressure in the upper, tapered position of the tower 1, the air stream enters through the outlets 27 into the lower part of the shaft 15 where it spreads along the two lower funnels 5 of the ejector systems 4 with the approach to the bell 28. Air flows separated by a partition 29 in the upper part of the ejector system 4 are reconnected .
