Description

The utility model relates to the field of wind energy, namely, devices for generating electricity.

Known wind power installation containing a support installed on the foundation, on the upper part of which is rigidly mounted block frame with six inlet nozzles-confusers on its vertical surface for air flow inlet, a diffuser for air flow outlet, installed in the lower part of the block frame wind turbine with a vertical a shaft that is kinematically connected to the electric generator by means of a lower gearbox and clutch (see patent specification RF No. 2156884, IPC F03D 3/04, publication September 27, 2000).

A disadvantage of the known installation is its lack of effectiveness.

The objective of the claimed utility model is to increase the efficiency of the installation.

The essence of the utility model is as follows.

A wind power installation containing a support installed on the foundation, on the upper part of which a block frame is rigidly mounted with twelve inlet nozzles on its vertical surface for air flow inlet and with a diffuser for air outlet on its top cover, a rotor turbine mounted in the block frame is rigidly connected with a vertical shaft, which is kinematically connected with the electric generator via a hydraulic brake system with a flywheel, a lower gearbox, which is made in the form of a rear axle abundance, body

which is rigidly connected with the foundation, and the coupling, while the vertical shaft is mounted in bearings with the possibility of rotation, and the support is made sectional. This improves the efficiency of the installation. The essence of the utility model is illustrated by drawings, where Fig. 1 shows a wind power installation, general view, Fig. 2 - the same, view A.

The wind power installation contains a support 2 installed on the foundation 1, on the upper part of which a block frame 3 is rigidly mounted with twelve inlet nozzles 4 on its vertical surface for air flow inlet and with a diffuser 5 on its upper cover for air flow inlet, installed in the frame 3 wind turbine 6, rigidly connected with a vertical shaft 7, which is kinematically connected to the electric generator 8 by means of a hydraulic brake system 9 with a flywheel 10, a lower gear 11, which is made in the form of a rear mo one hundred cars, the body of which is rigidly connected with the foundation 1, and the clutch 12. In this case, the vertical shaft 7 is mounted in bearings 13 for rotation. The support 2 is made sectional with the possibility of increasing, if necessary, its height.

Wind power installation works as follows.

Depending on the azimuth of the wind direction, the air flow selectively enters only the open working nozzles 4. The remaining rectangular fan trapezoidal nozzles are a screen that completely limits the negative inhibitory effect on the turbine blades, increasing its efficiency

Using structurally executed rectangular trapezoidal fan nozzles 4, the air flow is compressed in proportion to the ratio

The external area of the inlet and the internal area of the flow exit from the nozzle significantly increase the aerodynamic flow velocity, respectively, the kinetic energy on the turbine blades 6. As a result, an effective boost of the air flow is created.

A diffuser 5 with a lower diameter corresponding to the diameter of the turbine, and the upper diameter is approximately 0.2 larger than the lower diameter. The diffuser provides an efficient outflow of exhaust air flow in the turbine. Figure 2.

Using a single-stage gearbox 11, the revolutions of the working shaft with the clutch 12 are significantly increased with a rigid connection with the electric generator 8.

The design of the working trapezoidal nozzles 4 for boosting the air flow to the wind turbine 6 and the diffuser 5 allows to increase the efficiency of the installation.

The claimed utility model improves the efficiency of the installation.
