Description

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

A wind power installation is known, comprising a support installed on the foundation, on the top of which a block frame is rigidly mounted with twelve inlet nozzles on its vertical surface for air inlet air inlet and with a diffuser for air outlet on its upper cover, a rotor turbine installed in the block frame, rigidly connected to a vertical shaft, which is kinematically connected to the electric generator by means of a hydraulic brake system with a flywheel, a lower gearbox, which is made in the form of a rear axle a hundred automobiles, the body of which is rigidly connected to the foundation, and couplings, while the vertical shaft is mounted in bearings with the possibility of rotation, and the support is made sectional (see the description of the utility model for RF certificate No. 74670, IPC F03D 3/04 publication July 10, 2008 .).

A disadvantage of the known installation is the not fully used efficiency of the diffuser.

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 with twelve inlet nozzles is rigidly mounted on its vertical surface for air inlet air inlet and with a diffuser for air outlet on its upper 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 an abundance, the housing of which is rigidly connected with the foundation, and the coupling, the support is made sectional, with the possibility of rotation in the bearings, a vertical shaft is installed, at the upper end of which an impeller is rigidly mounted at the diffuser outlet.

This improves the efficiency of the installation.

The essence of the utility model is illustrated by the drawing, where Fig. 1 shows a wind power installation - a general view.

The wind power installation contains a concrete foundation 1, a lower technological section 2, an air intake base 3, rectangular wind nozzles 4, a diffuser 5, a wind turbine 6, a working vertical shaft 7, an electric generator 8, a flywheel 9, a gearbox 10, a section metal support 11, a clutch 12, thrust bearing 13, auxiliary shaft of fan 14, three-blade impeller 15, centering bearing 16 on a supporting metal crosspiece 17.

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 made rectangular trapezoidal fan nozzles 4, the air flow is compressed in proportion to the ratio of the external inlet area and the internal area of the stream exit from the nozzle, there is a significant increase in the aerodynamic flow rate, respectively, of the kinematic energy on the turbine blades 6. As a result, an effective wind blow of the air stream is created. A diffuser 5 with a lower diameter corresponding to the diameter of the turbine, and the upper diameter is 20% larger than the lower diameter. Structurally, the diffuser 5 provides an effective outflow of exhaust air flow in the turbine. In the proposed utility model, in order to further increase the installation efficiency, a three-blade impeller 15 is mounted in the upper part of the diffuser 15 on an auxiliary shaft 14 rotated in a centering bearing 16, rigidly mounted in a flat metal crosspiece 17. The design of the working trapezoidal nozzles 4 for inflating the air flow on the wind turbine 6 and diffuser 5 with a three-blade impeller 15 allows you to further increase the efficiency of the installation.

The claimed utility model allows to increase the efficiency of a wind power installation.
