Abstract

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering, particularly to wind power generators. Proposed windmill comprises rotary base, crossarms and power collectors. The latter represent columns furnished with sail-type flexible flags that partially envelope the former, the columns being fixed relative to crossarms. One edge of aforesaid flags is fastened to columns along their generating lines, while the other edge is jointed to appropriate edge of the opposite column flag with the help of links that allow flap turning downwind around one column and turning into the wind around opposite column.

EFFECT: higher efficiency.

Description

The invention relates to the field of wind energy, in particular to wind power plants.

Known wind power installation with a wind turbine [1], containing a tower, a rotary base on which the wind wheels and the stator element are mounted with a core, the latter through the air gap is connected with rotor elements made in the form of permanent magnets with pole tips and mounted on the ends of the blades of the wind wheel according to the invention, slots are made in the core of the stator element, and the permanent magnet of the rotor element is provided with a bandage installed in the slot of the stator core of the element.

Of all the known analogues, the wind power installation [2], which contains a vertical shaft mounted in a support with the possibility of rotation, rectangular blades mounted at equal distance from the shaft with the possibility of rotation around its axes parallel to the axis of the shaft, is the closest to the claimed combination of essential features [2] angular velocity, half the angular velocity of a possible rotation of the shaft, and in the direction opposite to the rotation of the shaft, while the blades are made in the form of a symmetric profile with a width of double the distance from the shaft edge to the axis of rotation of the blades, having a kinematic connection with the vane, and the angle between the plane of the vane and the plane of the blade at the moment of its coincidence with the shaft axis is 90 °.

Thus, the rotary vertical wind turbine contains a rotating base, traverses, columns with energy receivers and a central rack.

The disadvantage of this wind power installation is the low use of air flow.

The invention is aimed at increasing the use of air flow and, as a result, improving the energy of the installation.

The technical result, which consists in reducing the cross section of the wind receiver moving towards the flow, is that the energy receivers are made in the form of columns stationary relative to the traverse with flexible sail curtains partially covering them, with one edge of the curtains fixed along the generatrix of the columns, and the other edge connected with the corresponding edge of the curtain of the opposite column by rods, providing for the wrapping of the curtain around one column and the deployment of the curtain around the opposite column.

The invention is illustrated by drawings, where Fig. 1 shows a wind turbine, front view (wind direction is in the drawing), Fig. 2 is a top view.

The wind turbine contains a fixed base 1, transmission 2 to the consumer 3 (for example, an electric generator), a rotating base 4 with traverses 5, a central rack 6. Between the upper and lower traverses, wind energy receivers are installed, made in the form of columns 7 with flexible sail curtains 8 partially covering them type, representing a rectangular cloth. One edge 9 of the curtain is fixed along the generatrix of the cylindrical columns, and the other movable through the straps 10 are connected by rods 11 with the corresponding edge of the curtain of the opposite column.

The operation of the device. When the wind flow is in, the free edges of the shutter with the bar move from the neutral position - shown in dashed line in FIG. 2 to the operating position, that is, the shutter 8 is deployed at the right column in FIG. 2, and capturing the wind flow creates a moment that causes the engine to rotate counterclockwise. At the same time, the curtain of the extreme right column shown in Fig. 2, turning through the rod 11 connected to the bar 10, wraps the curtain of the extreme left column, which reduces the midsection of its cross section, and this, in turn, leads to a decrease in the opposing moment, i.e. to increase the useful moment.

Thus, the orientation of the curtains on the opposite columns is as follows:

1) On the columns, horizontally located traverses (figure 2) - the curtain on the right column is open, on the left is closed.

2) On a vertically located traverse (figure 2) - the curtains relative to the columns are in the middle position, while a small opening of the curtain at the upper column is not excluded.

A positive quality of this engine is, along with the simplicity of design, an automatic change in the direction of decreasing the cross section of a wind receiver moving towards the wind, which improves the efficiency of the device.

The technical and economic advantage of this wind power installation is the relatively high power of the installation, which makes it possible to build installations with a higher efficiency.
