Description

The invention relates to the field of alternative energy sources, namely wind energy, and can be used to produce electric energy for small villages, farms, geological stations, expeditions, etc.

Known wind turbine for the production of electricity, containing a wind turbine consisting of a blade propulsion with an electric generator [Roslyakov OA, Roslyakov P.O., Roslyakov IA, Roslyakova NG, Roslyakov A.O., US Pat. No. 94022615, 03/27/1996]. According to the invention, the wind turbine is mounted at the outlet end of the pipe, additionally equipped with a second, third and fourth wind turbines installed in pairs, coaxially and symmetrically with respect to the axis of the pipe, with each pair of coaxial wind turbines having a common support for bearings and the output of electrical wires from the internal cavities of the blade propellers.

The disadvantages of the known design are the difficulty in use and the need for a constant, targeted air flow.

Known wind turbine containing a vertical shaft with brackets fixed to it with rotary blades (SU 1377448 A1, F 03 D 3/02, 29.02.88). The reasons that impede the achievement of the required technical result when using the known device include the fact that in the known device, when the rotor rotates, the rotor blade that receives the wind flow is in the position of highest wind pressure (perpendicular to the wind) for a very short time. In the remaining positions of the blade, the pressure on it of the wind drops sharply. Large surfaces of the blades create large dynamic loads when closed. The use of a friction planetary mechanism limits the power transmitted by the wind turbine to the generator. When trying to increase the power of the wind turbine, the mass and inertial loads increase so much that its use becomes inappropriate. All of the above gives reason to argue that the known device will have low power and efficiency.

The closest in technical essence is an aerostatic wind turbine [application No. 94005792, 20.11.1995, Pavlyukov VD, Samsonov VA, Samsonov AV]. An aerostatic wind turbine consists of a balloon 1, along the axis of which there is a through profiled channel 2 with wind generators 3 and flow-straightening devices 4 placed in it, a cable cable 5 connecting the balloon 1 to a ground cable winch 6.

The disadvantages of the known design are the need to install it on elevations and open space, low efficiency, as well as the complexity of the design.

The objective of the invention is the creation of a more universal, affordable wind turbine.

The technical result is to increase the efficiency of the power plant, a more complete use of wind energy, simplifying the design.

The technical result is achieved by the fact that the air trap includes an air receiver, wind generators, while the air receiver is made in the form of a cone-shaped pipe on which a weather vane is installed, which captures the direction of the air masses. The air intake itself is mounted on a platform mounted on a rotary bed, and at the base of each generator there are adjustment brackets.

The drawing shows a diagram of an air trap, where the weather vane 1, air inlet 2, rotor blades 3, generator block 4, adjusting bracket 5, platform 6, rotary bed 7, foundation 8.

The weather vane (1) is stationary mounted on the air inlet, made in the form of a cone-shaped pipe (2), inside of which there are working blades (3) of the generator screws (4). The generator block (4) rests on a platform (6), which is connected with a rotary bed (7). Adjusting brackets (5) are provided under the generator block (4). The entire installation is based on the foundation (8).

The device operates as follows. The weather vane (1) captures the direction of the air masses. The air receiver in the form of a cone-shaped pipe (2), being in free rotation due to the rotational bed (7), is deployed in the direction of movement of the air masses. The air stream, having got into the trap, sets in motion the blades of the screws of the generators (3). Thus, the generation and accumulation of electricity occurs. Depending on the density and speed of the air masses, at the base of each generator, adjusting brackets (5) are installed.

The conical shape of the air inlet allows you to evenly generate wind energy, because in its widest part, the force of the air flow is higher, respectively, falling into its narrow part, the force of the air flow decreases.

The proposed device has several advantages compared to similar ones:

1. Does not require constant maintenance due to the simplicity of design;

2. High efficiency;

3. Mobility;

4. The ability to operate the device in any area without restrictions.
