(57) Abstract:

Usage: the invention relates to wind energy and for wind turbines. The wind turbine includes a rotor with a vertical axis of rotation, having the blades are symmetrical profile, the axis of rotation being located in a horizontal plane perpendicular to the vertical axis. The blades are mounted for rotation with a frequency half the frequency of rotation of the rotor, and connected with the control mechanism. The control mechanism consists of a kinematic transmission output shaft which is equipped with blades, and the input shaft is located coaxially inside the hollow shaft of the rotor and through the installation a worm gear associated with the inertial actuator, equipped with a mechanism for tracking the flow direction of the wind. The rotor may be composed of the same modules. 1 C.p. f-crystals, 4 Il.

The invention relates to wind energy and for wind turbines, which are oriented essentially to work in low wind range. Can be used mainly where the minor dimensions of the wind turbine height.

Known wind turbine with a rotor with a vertical axis of rotation, imeasy, half of the rotation frequency of the rotor, and connected to orientation relative to the wind direction control mechanism connected to the directional device (see and.with.USSR N 4132, CL F 03 D 3/00, published. 1927). This is a known technical solution for the considered class of wind turbines has drawbacks that limit its effectiveness. The important point is to ensure the perception of dynamic wind loads, as the wind wheel is large aerodynamic resistance, which, given the dynamic nature of veroniki and the greater its value, creates significant complexity to provide a wind turbine.

The increase of the power turbine only possible if structural changes.

The aim of the invention is to improve the reliability of a wind turbine; increased versatility due to the possibility of using modular units; the ability to change the maximum height of a wind turbine when it is in a working position in a particular area and Metropolitan.

The stated objective is achieved in that the rotor of a wind turbine is made of modules. The modules are interconnected, each of which SOS output shafts, and output shafts of the module are rotatable blades, the axis of rotation being located in a horizontal plane and perpendicular to the vertical axis of rotation of the rotor. The input shaft of each module is connected to the input shafts of the other modules and mechanical installation drive in the General control mechanism blades of a wind turbine. In this case the axis of the rotary blades are shifted relative to each other in the projection on the horizontal plane at an angle offset equal division 360othe total number of rotary blades. Installation drive installs and fixes the orientation of the blades relative to the wind direction. Mechanical installation the actuator is made in the form of the inertial actuator, mounting the worm gear and equipped with a mechanism for tracking the direction of wind flow.

The attached drawings depict: Fig. 1 - General view of the module of the wind turbine; Fig. 2 is a view of a of Fig. 1; Fig. 3 - layout and interconnection of the core parts and components of a wind turbine; Fig. 4 is a diagram for execution of manual mechanical control mechanism.

On the drawings and in the application materials indicated:

1 - skeleton of a wind turbine; 2 - rotor; 3 - blades; 4 - rotor shaft; 5 - volt the practical transmission; 8 - installation of the kinematic transmission, worm pair; 9 - inertial actuator; 10 - drive handle; 11 - tracking mechanism for the flow direction of the wind; 12 - electric generator.

Wind turbine is a sectional modular construction, each section is the same type of module elements intermodule fixing. The single module wind turbine (Fig.1-4) includes a rotor 2 with rotary blades 3 mounted on the frame 1 and is kinematically connected to an electric generator 12 through the rotor shaft 4. The turbine is equipped with an inertial actuator 9 is connected with the input shaft 5 via a set of kinematic gear, worm gear pair 8.

The module consists of the input shaft 5, which specifies the kinematic transmission 7, the two output shafts 6. Kinematic transmission 7 is designed as a bevel gear with a transmission ratio equal to 2. The device installation engine in the operating position contains an inertial actuator 9, the worm pair 8, the mechanism for tracking the flow direction of the wind 11. Instead of the inertial drive can be set the drive knob 10.

The wind turbine operates as follows. Tracking mechanism 11 detects the direction of the flow in the t position. This turn of the input shaft 5, through which the kinematic transmission 7 rotates the blade 3 to a position in which their movement for the wind flow is perpendicular position of their planes to the direction of wind flow. The blades 3 each revolution of the rotor do right away. Torque through the rotor shaft 4 is transmitted to the generator 12.
