Description

 The invention relates to wind energy, namely to wind power stations.

 A wind-driven installation is known, containing a vertical bearing frame with a tail truss for wind orientation and jumpers located on a wind-wheel frame with blades connected to an electric generator and diffuser shells (see SU 1132046 A, class F 03 D 1/02, 12/30/1984 )

 The disadvantages of the installation include low efficiency and installation power.

 Known wind power unit containing a rotary housing with windows, a frame placed inside it, an annular guiding apparatus, a wind transducer with trellised plates, latches, rods with cables and a pipeline (see SU 1384818 A1, class F 03 D 5/00, 03/30/1988 )

 The disadvantages of the unit include low efficiency and reliability due to significant loads on the case, as well as the complexity of the design.

 A known wind turbine containing two coaxial wind wheels with internal and external shafts, a power transmission, an electric generator and a shell (see SU 1048158 A, class F 03 D 1/02, 10/15/1983).

 The disadvantages of the wind turbine include a low coefficient of utilization of wind energy, low efficiency of the unit at startup in case of low wind speeds, low reliability.

 Known wind power station containing a housing mounted with the possibility of rotation in a horizontal plane on a support under the pressure of the wind on a stabilizer mounted on the housing, the set of essential features adopted as the closest analogue (prototype) of the invention (see RU 2003832 C1, CL F 03 D 1/02, 11/30/1993).

 The disadvantages of the station include low efficiency, increased noise level, difficulty in manufacturing due to the need to use "high technology".

 The technical result, which consists in simplifying the design and ensuring noiseless operation, is achieved due to the fact that in a wind power station comprising a housing installed with the possibility of rotation in a horizontal plane on a support under the pressure of the wind against a stabilizer mounted on the housing, according to the invention, the housing is made in the form of a frame, the sides of the frame are made in the form of axes on which shafts with blades are mounted, and the shafts are mounted with the possibility of synchronous rotation in a plane transverse to the longitudinal axis orpusa and kinematically connected to the shaft of the generator, and the frame fastened flap covering the wind from the space between the rollers.

In FIG. 1 shows a wind power station (front view);
in FIG. 2 shows a wind power station (top view).

 The wind power station contains a housing 1 made in the form of a frame and mounted with the possibility of rotation in a horizontal plane on a support 2 under the pressure of the wind on a stabilizer 3 mounted on the housing 1, the sides of the frame are made in the form of axes on which shafts 4 with blades 5 are mounted, moreover, the shafts 4 are mounted with the possibility of synchronous rotation in a plane transverse to the longitudinal axis of the housing 1, and are kinematically connected with the shaft of the electric generator 6, and the shutters 7 are mounted on the frame, covering the space between the shafts 4 from the wind th transmission 8, which provides mechanical connection between the shafts 4.

 Wind power station operates as follows.

 Under the pressure of the wind on the stabilizer 3, the housing 1 rotates on a rotary support 2 and occupies an operating position, i.e. located along the wind. In this position of the station, the wind presses on the blades 5, located outside the space between the shafts 4, and on the shutter 7, but does not press on those blades 5, which are located in the space between the shafts 4 and the shutter 7, and the resulting moments of wind pressure blades 5, turning shafts 4 in opposite directions. The shafts 4 rotate synchronously, in order to avoid damage to the device during non-synchronous rotation, and the synchronization of rotation provides a mechanical connection between the shafts 4, for example, in the form of a gear 8. The rotation of the shafts 4 is transmitted to the generator 6 connected to them, and the energy generated by the generator 6 is transmitted to the consumer.
