DESCRIPTION OF THE INVENTION
The invention relates to agricultural engineering and can find application in the development of machines with wind turbines for various applications: soil cultivation, water supply to mills, river and sea vessels.
A wind turbine is known, comprising a vertical shaft with radial traverses, connected by vertically axial hinges with blades, spring-loaded rods installed in the traverse chambers and connected to the blades, a generator connected to the shaft by means of a multiplier, the drafts being in the form of a link, Equipped with adjusting weights mounted on them, and spring-loaded with the help of pairs of coaxially mounted coil springs, the vertical axis of the hinges being aligned with the centers of mass of the blades (author of USSR 1820024, class F 03 D 3/00, 1993).
The closest in technical essence to the proposed technical solution is a rotor windmill comprising a rotor housed in a housing mounted on a vertical shaft (US Pat. No. 1460114, class F 03 D 3/00, 1923).
The known wind turbine has a complex design, low reliability, high metal consumption and is limited in application.
The invention solves the problem of creating a simple, reliable design of a wind turbine using modern light materials (plywood, plastic, textolite, wood, thin metal) with a wide range of applications in various sectors of the national economy (when creating machines with a windmill for harvesting barley, rye, maize, Mowing grass, etc.) with the protection of the structure in adverse weather conditions (hurricanes, vortices, etc.).
The problem is solved by the fact that in a rotor windmill containing a rotor placed in the housing mounted on a vertical shaft, the rotor is formed with two wings in the form of two half cylinders, displaced relative to each other by a distance not less than their radius and fixed rigidly between the upper And the lower discs, the casing is provided with flaps with a large swing for entry and exit of the air flow and directing it to the wings of the rotor and is made in the form of a diffuser, the balancers of the rotor rotation are introduced, and aerodynamic pockets are formed on the lateral surface of the upper and lower discs.
Preferably, the rotational balance of the rotor is in the form of pipes fixed rigidly between the upper and lower discs in the connectors between the rotor wings.
Advantageously, the rotor wings are made with flush flaps in the form of a plate-shaped concave wing, which are installed with a clearance relative to the outer surface of the wings.
It is expedient to mount the body flaps with the possibility of starting the rotor in the opened position and stopping the rotor in the closed position.
The carried out analysis of the state of the art, including the search for patent and scientific and technical sources of information and the identification of sources containing information on analogues of the claimed invention, makes it possible to establish that the applicant has not found technical solutions characterized by features identical to all the essential features of the claimed invention. The definition from the list of identified analogs of the prototype made it possible to identify a set of significant (in relation to the technical result observed by the applicant) distinctive features in the claimed object, set forth in the claims.
Consequently, the claimed invention meets the requirement of "novelty" under current legislation.
The information about the popularity of the distinctive features in the totality of the features of the known technical solutions with the achievement of the same as for the claimed device has no positive effect. Based on this, it was concluded that the proposed technical solution meets the criterion of "inventive level".

In Fig. 1 shows a proposed wind turbine, FIG. 2 shows the rotor of the windmill, FIG. 3 is a sectional view of AA in FIG. 2.
The rotor windmill consists of a rotor 2 arranged in the housing 1 with the possibility of rotating the rotor 2 mounted on a vertical shaft 3 and made with two wings in the form of two half-cylinders 4, 5 with a concave portion facing each other and displaced with respect to each other by an amount not less than the concavity radius And fixed rigidly between the upper and lower discs 6, 7.
The body 1 is made in the form of a cylindrical diffuser, the walls of which are made with a variable cross-section and, for example, of foam. The body 1 is provided with flaps 8, 9 with a large swing for entry, outlet of the air flow and directing it to the wings 4, 5 of the rotor 2. In the upper and lower parts of the flaps 8, 9 it is expedient to install deflectors to create a corridor for the passage of a large volume of air flow. The front flaps 8, 9 serve to receive airflow, and the rear flaps (not shown) control the airflow at the outlet (serves to discharge the airflow). The upper part of the body 1 is the roof of the rotor 2, on top of which is secured a fairing covering the upper end of the shaft 3 of the rotor 2 and the seat where the bearing of the upper end of the shaft 3 of the rotor 2 is located. In the bottom of the housing 1, in the center, there is a seat for supporting the bearing for the lower end of the shaft 3 rotors 2. In the lower part of the left leaf, a deflector perpendicularly is placed to direct the air flow to the wing.
The body 1 is rotatable 360 ° and locked in any position, for example, with a monorail and bearing carriages (not shown).
The body leaves and serve as a manual drive of the rotor 2.
The body casing in the open position drives the rotor 2, and in the closed position, the rotor 2 stops.
Between the upper and lower discs 6, 7, in the connectors between the wings of the rotor 2, the balancers 10 for rotating the rotor 2 are formed in the form of pipes to ensure uniform rotation of the rotor 2. The aerodynamic pockets 11 are formed on the side surface of the upper and lower discs 6, 4, 5 of the rotor 2 are made with blow-in flaps 12 in the form of a plate-shaped concave wing, installed with a clearance relative to the outer surface of the wings 4, 5.
The shutters 8, 9 of the body 1 are mounted with the possibility of starting the rotor 2 in the opened position and stopping the rotor 2 in the closed position.
The vertical shaft 3 can be made, for example, from a steel pipe and fixed between the upper and lower steel discs 6, 7 by means of flanges. The vertical shaft 3 is the power take-off shaft, it takes the rotational motion of the wings 4, 5 and transfers the rotation to the reducer.
The upper and lower disks 6, 7 serve to connect all the main parts of the rotor.
The wings 4, 5 of the rotor can be made of 0.8 mm thick ornamental steel. The ends of the wings 4, 5 are flanged for rigid attachment to the discs 6, 7 of the rotor 2.
The aerodynamic pockets 11 can be formed, for example, by edging the side surfaces of the discs 6, 7 with a metal band on which the metal peaks are rigidly fixed through the gaps.
Aerodynamic chambers 11 serve to increase the speed of rotation of the rotor 2.
The rotor windmill works as follows. When the front and rear doors of the body 1 are open, the air flow is directed to the wings of the rotor 2.
Wings 4, 5 perceive the main force of the air flow, their rotational motion drives a vertical power take-off shaft 3 that rotationally drives the gearbox or gearbox. When the front and rear flaps are closed, the air flow to the wings 4, 5 stops, the rotor 2 stops.
The proposed design of the wind turbine is technologically feasible, reliable, durable, easy to use.
