DESCRIPTION OF THE INVENTION
The invention relates to the field of wind power engineering, namely it is a part of the wind power plant equipment.
A wind turbine is known comprising a housing with an inlet confuser, a neck and an outlet diffuser, a shaft disposed in the housing, a turbine and a rotor blade, the confuser being provided with guiding blades, the rotor being rotated relative to the shaft and arranged as a hub with fan blades and an annular rim, Connected with the ends of the blades (see SU, 1590626 A1, class F 03 D 1/04, 07.09.1990).
The shortcomings of the windmill design include a low coefficient of wind energy use due to the complexity of the design and low reliability of the installation.
A windmill is known that contains a guide tube consisting of a bell, conical parts and an outer conical casing, inclined partitions, impeller, annular channel and valves (see SU, 3459 A, cl. F 03 D 1/04, August 31, 1927) .
The disadvantages of the windmill design are low efficiency and the lack of the ability to automatically adjust the rotational speed of the impeller.
A wind turbine is known that contains a working channel with a diffuser at the outlet and a turbine shaft with working blades rigidly fixed at a certain angle to its axis located in the channel (see SU 1523707 A1, class F 03 D 1/04, 23.11.1989), adopted On a set of essential features for a prototype.
The disadvantages of the proposed as the closest analogue (prototype) of the wind turbine is the low efficiency of the use of wind-power flow energy.
The technical result, consisting in increasing the efficiency of the wind turbine and increasing the wind energy utilization factor, and achieving the process of automating the turbine rotation speed to a predetermined optimum value, is provided by the fact that in a wind turbine containing a working channel with a diffuser at the outlet and a turbine shaft located in the channel With working blades rigidly fixed at a certain angle to its axis, according to the invention, the blades are fixed to form at least one row, at least one row of guide blades is rigidly fixed on the inner surface of the channel, the guide blades of the output row being parallel to the axis of the shaft, In addition, in the channel between the turbine and the output diffuser there is a centrifugal regulator of the wind flow rate connected by its shaft to the turbine shaft through the reducing gear, and the regulating flaps in the form of a trapezium, the plane of which is directed towards the wind flow, are rigidly attached to the leading rods of the regulator.

In Fig. 1 shows a self-regulating wind turbine (general view); In Fig. 2 is a sectional view AA in FIG. 1.
The turbine contains a working channel 1 with a diffuser 2 at the outlet, a shaft 3 of a wind turbine located in the channel 1, a wind turbine wheel 4 with working blades 5, intermediate guide vanes 6, output guide vanes 7, a conical gear pair 8, an output shaft 9, a reducing gear 10 , A roller bearing 11, a shaft 12 of a centrifugal regulator 13, a fixed ring 14, a drive rod 15, a damper 16, a load 17, a driven rod 18 of a centrifugal regulator 13, a return spring 19 and a movable ring 20.
DEVICE WORKS AS FOLLOWING
The wind flow enters the working channel 1 of the self-regulating wind turbine and, striking the plane of the working blades 5, causes them to rotate the impeller 4 rigidly seated on the shaft 3. When the shaft 3 of the wind turbine rotates and the shaft 12 of the centrifugal regulator 13 connected to it through the reducing gear 10, The centrifugal force tending to lift the load 17, and hence the upper end of the driving rod 15 with the control damper 16. If this centrifugal force is greater than the sum of the opposing forces, the rotating control flaps 16 rise upward and, overlapping the cross section of the working channel 1, prevent the passage Wind flow, reducing its speed. With the decrease of this speed, the rotation speed of the wind turbine also decreases, the centrifugal force decreases and the control flaps 16 drop. This will continue until the rotation speed is established, at which the centrifugal force and the sum of the opposing forces will be balanced.
Thus, self-regulation of the wind turbine of its rotation is performed, since in the initial position, when the rotation speed of the wind turbine is optimal, the conditions of equilibrium of forces are observed:
P ц = 
P pr
Where P ^ is the centrifugal force, H; P pr - the sum of the opposing forces, N.
P pr = P vp + P pr.v. + M
Where P. - the force of the wind flow acting on the surface of the control flaps, H;
R pr.v. - force of the return spring, N;
M - weight of cargo, kg.
In this case, the control flaps 16 are in their lowest position, i. E. They are lowered downwards and do not interfere with the passage of the wind flow through the passage section between them and the working channel 1. With increasing wind speed, and with it the speed of rotation of the wind turbine, the centrifugal force sharply increases,
P ц = M · 
2 · r
Where M is the mass of the load, kg; - angular velocity, rad / s;
R is the radius of rotation of the load, m,
And, acting on cargo 17, overcomes all the above opposing forces, lifting up the regulating shutters 16. Despite the fact that their surface area is smaller than the sectional area of the passing wind flow, due to their rapid rotation for a certain short time interval, they overlap many times The area of its cross-section and thus significantly increasing the aerodynamic resistance, reduce the speed of the wind flow. The higher the wind speed, the higher the cargo 17 rises and the greater the cross section of the wind flow is blocked by the rising and rotating control flaps 16. With the decrease in the speed of the wind flow in the working channel 1 and the rotation speed of the wind turbine, they fall to a position where the centrifugal force is balanced by the sum Opposing forces.
