Description

The utility model relates to energy, in particular to devices for producing mechanical or electrical energy through the use of air flow.

There are various designs of devices that use air flow to generate energy, for example, devices according to RF patents Nos. 74969, 59747, 727229, 2165034, 2248463, 2327058, 2009369, 2246029, 22316883, etc.

The closest technical solution is a wind turbine containing a housing with sides and a drum rotatably mounted therein and radially arranged blades, while the housing closes the lower half of the drum, characterized in that the wind turbine is further provided with a guide screen, which is located at an angle to the horizontal line passing through the axis of the drum, and brought to its generatrix (patent for a utility model of the Russian Federation No. 81774, publ. 03/27/2009) - prototype.

The disadvantage of this design is the low power of the wind turbine, the inability to automatically orient the working body (body) relative to the direction of movement of the wind flow.

The technical task of the claimed utility model is to increase the power of the wind turbine, providing automatic orientation of the wind turbine housing relative to the wind flow.

The technical problem is achieved in that the wind turbine contains a housing with a rotary drum mounted therein and blades radially located in the drum, the wind turbine is equipped with a guiding screen that is connected to its generatrix, and the wind turbine is additionally equipped with a second drum with a guiding screen, the guiding screens are angled to each other or parabolic, and the drive shafts of the drums, through a gearbox, are interconnected. Through the apex of the corner or parabola, an axis passes relative to which the body can rotate. Drums can be mounted vertically. The device can be placed on a support made vertically.

Comparison of the proposed solution with the prototype shows that it differs in the following features:

- the wind turbine is additionally equipped with a second drum with a guide screen;

- moreover, the guide screens are located at an angle to each other or parabolic;

- drive shafts of the drums are connected through a gearbox;

- drums are mounted vertically;

- through the apex of the angle or parabola formed by the screens, an axis passes relative to which the body can rotate.

- the wind turbine is mounted on a support made vertically.

Therefore, we can assume that the claimed utility model meets the criterion of "novelty."

The utility model can be manufactured on standard equipment using well-known technological processes, therefore it meets the criterion of "industrial applicability".

Figure 1 schematically shows a wind turbine with a vertical arrangement of drums (top view), Figure 2 schematically shows a wind turbine with a vertical arrangement of drums mounted on a support that is made vertically, Figure 3 and Figure 4 shows the arrangement of the drums at an angle to each other to a friend, and the wind turbine is mounted on a horizontal plane, Figure 5 shows the kinematic diagram of the wind turbine with vertically mounted drums, Figure 6 shows a parabolic arrangement of the screens of the wind turbine.

The wind turbine consists of a housing 1 (Figure 4) on which two guides of the screen 2 are installed at an angle to each other (Figure 3). The screens 2 are connected to the generatrix of the drums 3 with the blades 9. Figure 3, 4 schematically shows a wind turbine with drums mounted at an angle to each other. The drive shafts 8 of the reels through a bevel gear 4 are interconnected (Figure 4). When performing a wind turbine with vertical drums - it contains a housing 1 (Figure 1), a support 10 made vertically, which passes through the top of the angle formed by the screens 2 (Figure 2). The drive shafts 8 are connected through gearboxes 4 with a common shaft 5, on which has a drive pulley 6 for driving the pulley of the generator 7 (Figure 2), (a generator 7 with a drive pulley 6 is shown only in Figure 1).

The device operates as follows. The housing 1 of the wind turbine is installed on a horizontal plane (Figure 4, Figure 3), for example, on the ground, the flat roof of the building, in the car body, so that the guiding screens 2, located at an angle to each other, are directed towards the wind flow. When an air flow occurs, thanks to the two guide screens 2, the drums 3 and, accordingly, the drive shafts 8 are connected through a gear 4. If the wind turbine is mounted on a support 1, made vertically, then the axis of the support 1 passes through the top of the corner (Figure 1) or parabola (6), formed by screens 2. This design allows you to automatically orient the wind turbine housing towards the air flow by rotating the rigidly interconnected reflecting screens 2 around the support 1. When the drum rotates 3 newly torque is transmitted through drive shafts 8 and reducers 4 on the shaft 5 and then through the pulley 6 to a generator 7.

Thus, the claimed utility model, by installing an additional drum with a screen, increases the power of the wind turbine, and when using a support made vertically, it allows you to automatically orient the body of the wind turbine relative to the wind flow.
