DESCRIPTION OF THE INVENTION
The invention relates to wind power, namely to power plants.
Wind power plants are known (see, for example, RF patent No. 2018028, MCI F 03 D / 00, USSR autos NN 1682621, 1560781, 1471709, 1242636, class F 03 D 1/00) containing a tower (Mast), one or more self-aligning windscreens, a generator mounted directly on the wind wheel on one axis with it, and a transmitting connection using a generator installed at the base of the tower.
The disadvantage of the examined wind turbines is a relatively low efficiency.
A wind power plant is known (see German patent N 2932293, class F 03 D 1/02 - prototype), containing a supporting tower (tower), two wind wheels, a self-aligning rotary head, two generators, one of which (upper) is mounted in a rotary head On the same axis as the wind wheels. Another (lower) generator is mechanically connected by shafts to the first (upper) generator.
The disadvantage of the considered wind power plant is a relatively low efficiency.
The objective of the proposed technical solutions is to increase the efficiency and power of the wind power plant by creating an air turbine with the most efficient use of wind energy.
The stated task is achieved by the fact that in a wind power plant (variant 1) containing a hollow tower with an outlet in the lower part with a hollow self-aligning head at the top, two wind wheels, the first of which is mounted on an axis fixed in the head, and an energy generator having an outlet On the consumer, it is proposed to provide the head with a guide device fixed in the inlet and on a common axis with the first wind wheel fixed free, the generator should be installed at the outlet of the cavity of the tower, and the second wind wheel should be installed on the generator shaft with the possibility of aerodynamic interaction with the first wind wheel, Formed by the cavities of the head and the tower.
The above task is achieved by the fact that in a wind power plant (variant 2) containing a hollow tower with an outlet in the lower part with a hollow self-aligning head on top, two wind wheels, the first of which is mounted on an axis fixed in the head inlet, and an energy generator , Having access to the consumer, it is proposed to make the head in the form of a tube, while at the same end and on the same axis with the first wind wheel fix the first guiding device, the cavities of which are the first input of the head. The cavity of the tower is equipped with a curved pressure line and the upper end is fixed between the first and second guiding apparatus fixed concentrically and in one plane at the other end in the head cavity. And on the axis of the guide device, fixed inside the curved pressure line, install the third wind wheel with the possibility of aerodynamic interaction of its blades with the cavities of both guiding devices. Install the generator at the lower outlet of the pressure line. On its shaft, install a second wind wheel with the possibility of aerodynamic interaction with the third wind wheel.
The wind power plant for both variants may be provided with an additional curved outlet pressure line, which is arranged concentrically, for example, with respect to the surface of the tower cavity and the pressure line.

In Fig. 1 shows the first version of the wind turbine; In Fig. 2 - the second version of the wind turbine.
The wind power plant (option 1, figure 1) contains a hollow tower 1 with an outlet at the bottom. At the top of the tower 1, a hollow (self-aligning) rotary head 2 is rotatably mounted, in the inlet opening into the cavity of which the wind wheel 5 is freely fixed to the axis 3 of the guide apparatus 4. The energy generator 6 having an outlet to the consumer is installed at the outlet of the cavity of the tower 1, This second wind wheel 7 is mounted on the shaft of the generator 6 with the possibility of aerodynamic interaction with the first wind wheel 5 by means of a pressure line formed by the cavity of the rotary head 2 and the cavity of the tower 1.
The wind power plant (option 2, figure 2) contains a hollow tower 1 with an outlet at the bottom. At the top of the tower 1, a hollow (self-aligning) swivel head 2 is rotatably mounted. The swivel head 2 is in the form of a pipe. At one end, on the common axis 3, the guiding device 4 and the wind wheel 5 are fixed. The energy generator 6 having access to the consumer is installed at the outlet of the tower 1 and is equipped with a wind wheel 7. The cavity of the tower 1 is provided with a curved pressure line 8. At the other end of the rotary head 2 in its cavity fixed wind wheel 9 on a common axis with a guiding device 10, fixed inside the curved pressure line. The upper end of the pressure line 8 is fixed between the housings of the guiding apparatuses 10 and 11.
The pressure line 8 (for each variant) may be provided with an additional curved outlet pressure line 12, which is arranged concentrically, for example, with respect to the surface of the cavity of the tower 1 and the pressure line 8.
In addition, if necessary, the wind turbine may include an energy storage device, for example, a battery installed near the power generator.
The wind power plant (option 1, figure 1) works as follows.
Under wind pressure, the rotary head 2 is self-adjusting in the direction of the maximum wind speed. When the wind reaches a sufficient speed, the wind wheel 5 starts to rotate. Air enters the working blades of the wind wheel 5, giving it energy, and then in the axial direction through the straightening device 4, which is a fixed blade, between which the air velocity decreases and its pressure increases, enters the pressure line (the cavity of tower 1) and the second wind wheel 7, mounted on the shaft of the power generator 6. The kinetic energy of rotation of the wind wheel 7 is converted by the generator 6 into an electric one, which can be immediately transferred to the consumer, and can be stored in the battery with subsequent use.
The wind power plant (variant 2, figure 2) operates as follows.
Under wind pressure, the rotary head 2, made in the form of a pipe, is self-aligned in the direction of the maximum wind speed. When the wind reaches a sufficient speed, the wind wheel 5 starts to rotate. Air enters the working blades of the wind wheel, giving him energy. Further, the air moves axially through the rectifying apparatus 4, while its velocity decreases and the pressure increases. After the rectifying apparatus 4, the air already under pressure through the guide apparatus 1 accelerates the rotation of the wind wheel 9, which in turn gives pressure to the incoming dynamic air pressure on its blade, increases the speed of its movement through the straightening apparatus 1, which further increases the pressure of the air moving along the pressure line 8 On the wind wheel 7 of the energy generator 6.
For the convenience of taking energy out of the pressure main, its output can be provided with an additional curved output line 12.
The difference of this wind turbine from the previous version is its capacity increase due to the above design features.
Wind power plants of the proposed design can be represented by a series of capacities and sizes depending on the energy demand and climatic conditions of operation, Do not undergo icing and work even from weak winds due to the design of the installation as a whole and the closure of the wind-wheels in the air inlet, in particular.
