    description
    A WIND POWER PLANT WITH WIND FENDER TECHNICAL AREA
    The invention relates to a wind turbine with wind catchers with a mounted on a mast vertical axis of rotation, for which at least one cylindrical rotor is provided with elongated wings, which is connected to a power generator and mounted in an annular stator with wind vanes.
    STATE OF THE ART
    The prior art for wind turbines with a vertical axis of rotation is known for a variety of types. For example, the Savonius system consists of two horizontal circular disks mounted on a vertical rotor axis, between which two or more semicircular curved blades or vanes are mounted vertically. The blades are offset from one another so that a portion of the wind is diverted from the blade sides open to the right and left, and can act on the back of one of the blades concave there. The mode of action is based both on the aero-dynamic buoyancy, as well as on the resistance-induced propulsion.
    The blades are exposed to the Savonius rotor due to the constant change of Anstell¬winkel to the acting flow load changes that can cause, in interaction with the Flehkräfte, vibrations or material loads. A pronounced imbalance, due to the cyclically different load of the flow during rotation, is characteristic of the Savonius rotor, even if the weight distribution is perfectly balanced. The disadvantage is also the low efficiency.
    In the Darrieus wind turbines rotate the rotor blades on the generatrix of a geometric rotation figure with a vertical axis of rotation. The geometric shape of the rotor blades is complicated and expensive to manufacture. Darrieus rotors, like horizontal axis rotors, are preferably built with two or three rotor blades. Darrieus wind turbines are unable to start by themselves.
    US 7329965 discloses a vertical axis wind turbine which provides a rotor and a stator with vertical profiled blades. The split and shifted rotor blades have a horizontal cross-sectional arc shape in the direction of the center, which narrows to the edges. The blades of the stator are on one side flat and convex on the other. The rotor blades and the stator are mounted on top and bottom of concentric circular rings. The drawback of this solution is the considerable cost of producing displaced blades and turbulence in the wind turbine, which results in a reduction in the efficiency of the wind turbine.
    The invention has the object to propose a similar type of wind turbine, in which lower production costs less noise and much higher performance, can be achieved by the arrangement and shape of the new wings, the wind deflectors and wind catcher.
    SUMMARY OF THE INVENTION
    The invention comprises an aerodynamic vertical axis wind turbine, which has a rotor with vertical wings, a cage-shaped stator with Windleitschaufel and a käfigför¬mige wind catcher combination, the power generation by optimized wings, wind deflectors and wind catcher, by increasing the wind speed and Pressure without back pressure and the improvement of the laminar flow of the wind both around and through the device optimized. The rotor is connected to a power generator.
    The one horizontal rotor blade cross-section has the formula for the Kurvensegmentbe- calculation whose end points coincide with the end points of the segment of the wing with A.
    The curve segment calculation begins with the drawing of an xy-axis. From the intercept 0 of the xy-axis, a line of length A is drawn vertically, then the radius of curvature RI = A / 3.7 to 3.9 up to the intersection with the x-axis, then the radius of curvature Rll = A / 2.6 to 2.8 up to the point of intersection with RI and then the radius of curvature Rill = A / 0.48 to 0.52 to the point of intersection with Rll and the intersection with they axis.
    The horizontal section of the wind vanes has the shape of a circle segment whose end points coincide with the end points of the segment of length B - the radius of the circle is R = B / 1.08 to 1.14.
    In a preferred embodiment, two arranged in the opposite direction of rotation wind turbines are on top of each other and drive a generator. The upper wind turbine is connected to the generator rotor and the lower wind turbine to the generator stator.
    In order to achieve a higher performance, the wind turbines must be built übereinander in the form of a tower. Already two towers can be connected by vertical steel structures and equipped with solar modules.
    By the vertical alignment of several wind turbines one above the other, in the form of wind power columns and the setting of several wind power columns in single, double, triangular, trapezoidal or rhombus or multiple form (Figure 8), the constructions can stiffen and the force of the wind optimal use.
    In order to achieve a higher output, the solar modules are mounted on a steel frame of a swivel frame. This special substructure with modules is mounted on the wind turbine mast with the aid of the vertical and horizontal rotary axis assembly. The drive of each axle is equipped with a small electric motor and a GPS control. An electric motor is used to set a horizontal position from the vertical position (depending on the height of the sun). The second electric motor follows the sun during the day from sunrise to sunset. After sunset, the rotating frame automatically moves to the horizontal position and waits until the morning when it faces the sun in an easterly direction. In strong wind, the rotating frame automatically switches to the horizontal position. This invention allows Opti¬male use of the energy of the sun and the wind.
    A higher power can be achieved if a rotatable or pivotable plate is mounted on the mast of the wind turbine, which is equipped with solar modules. The plate holder is equipped with drives in order to be positioned in a horizontal or vertical position and to be able to turn around the mast.

    Wind turbine is supplied; (FIG. 14) shows the supplied quantity of the additional, compressed wind (the dashed line) to the rotor blade.
    THE TECHNICAL OBJECT OF THE INVENTION
    The wind turbine with a vertical axis of rotation, the basic Ausführunginin (Figure 1) and (Figure 2) is shown, has a cylindrical rotor (1) gebo¬genen in particular shape wings (2), which is connected to a power generator is. The rotor rotates in an annular stator (3). The stator (3) has upper and lower collars, on which wind vanes (4) are arranged symmetrically around the circumference of the stator (3) to steer the wind symmetrically into the center of the vanes (2) and the rotor (1), respectively , and thus serve as a system to increase the amount and additional compression of the wind. This system consists of vertical (5) and horizontal wind catchers (6) installed on the stator. The wind catcher consists of parts of the upper and lower wind catcher with an inclination of the conical surface of 45 ° facing each other and connected to each other with the vertical Windfän- like. This system increases the amount of wind (Figure 14) and greatly increases the speed and wind pressure on the blades (2) of the rotor (1). This construction allows the wind turbine to increase its productivity by 30%. This invention can better utilize the power of the wind through the optimized wing shape, directs a greater amount of wind to the wind turbine under pressure, allows for higher speed and thereby greatly increases the efficiency of the wind turbine. The wind turbine is very quiet, about 35 DB, and suitable for mounting near buildings and on roofs of Wohnhäu¬sern. This wind turbine design allows it to start its work already at a wind speed of less than 1 m / s.
    An important aspect of the invention is the shape of the rotor blades (2) and the Windleit¬ (4).
    As can be seen from (FIG. 3), which represents a preferred geometry of the rotor blade (2), a horizontal cross-sectional shape of the rotor blade (2) has a curve segment whose end points (X), (Y) coincide with the end points cover the segment of length A.
    The curve segment calculation begins with the drawing of an xy-axis. From the intersection point 0 of the xy axis, a line of length A is drawn perpendicularly, then the radius of curvature RI = A / 3.8 up to the point of intersection with the x-axis, then the radius of curvature Rll = A / 2.7 up to the point of intersection with RI and then the radius of curvature Rill = A / 0.5 up to the point of intersection with Rll and the intersection with they-axis.
    The horizontal section of the wind vanes has the shape of a circle segment whose end points coincide with the end points of the segment of length B - the radius of the circle is R = B / 1.11.
    Such specified forms of the wings (2) and wind deflectors (4) allow on the basis of the values A and B proportionally large wings and wind deflectors for wind turbines in different dimensions.
    This configuration of the wings (2) and wind vanes (4) having the described geometry together with the vertical (5) and horizontal (6) wind collectors in the form of a cylindrical basket provides optimum conditions for concentrating the wind flow and the air flow in the wind turbine for the maximum Use of wind energy, as shown in (Fig.11) and (Fig.14).
    The basic construction of the wind turbine of (Figure 1) can serve as a module of the construction kit. An example of such a wind turbine network of five modules is shown in (Fig.5) and (Fig.6).
    Thus stacked wind turbines may be a single power generator or each wind turbine may separately power its own power generator.
    [0026] From the point of view of the use of wind energy, the attitude of the two wind turbines is

    layer columns as in (Fig.5) and the connection of the one with the other with steel profiles (7) and the covering with plates or solar modules (8) are advantageous. The resulting surface performs the function of additional wind catcher and directs additional wind to the one or the other wind turbine (Figures 12, 13). Examples of two, three and more such configurations are shown (Figs. 5, 6, 7 and 8). The merging of wind turbines strengthens the static and creates additional wind catcher and air flow. The vertical structure (7) can also be equipped with solar modules (8), as can be seen from Figs. 5-7. The basic wind turbine module (FIGS. 1 and 2) is used for a further embodiment (FIG. 8). In this arrangement of two basic modules, the rotor from the upper base module is connected to the rotor of the generator and the rotor from the lower base module is connected to the stator from the generator, so that the module rotors are mirror images of each other. This means that the rotors (1) of module (5) and (6) in Fig. 8 rotate in opposite directions. The rotor and stator are part of the power generator and rotate in opposite directions, which increases the relative speed and thus the electrical power. The wind turbine in this embodiment begins even at low Windge¬ speeds of about 0.5 to 1 m / s. The installation is particularly suitable in regions with low wind speeds. In another embodiment, the wind turbine is mounted to the mast on which a tilt plate (Fig. 10) is mounted with solar modules and directs that surface to the wind turbine for additional wind. The tilting plate (Fig.10) is fixed on a steel support (11) rotatably mounted on a turbine mast (9). The steel bracket (11) is provided with a drive for horizontally and vertically rotating the pivot plate (10) about the mast (9). The swivel plate (10) is equipped with solar modules (8). The position of the tilting plate (10) can be adjusted both with respect to the wind direction and relative to the position of the sun. The control of this system is equipped with sensors and programmed so that even with GPS assistance the optimal variant of the settings in the direction of the sun or the wind direction can be adjusted. If more energy comes from the wind turbine than from the solar modules, then the tilt plate turns in the wind direction and directs as much wind as possible in the Windkraftan¬lage. When the sun shines strongly and the wind is weak, the tilting plate sets its position to the sun and goes with the sun all day long. If the wind is too strong, place the tilt plate in a horizontal position. When the wind subsides, the tilting plate is placed in the corresponding desired positions. The wind turbine allows according to the invention, a better use of wind energy, partly by optimal shape and adjustment of the wings, partly by optimal shape and adjustment of the wind deflectors, partly by the Wind¬fänger, which compress the wind and increase the wind speed on the wing.This increases the rotor speed and the efficiency of wind energy. The wind turbine is very quiet with a noise level of 35 dB and therefore suitable to be installed near buildings or on the roofs of residential buildings. It also operates at a wind speed of 1 m / s up to speeds under thunderstorm conditions. The invention enables the construction of wind turbines of various types of horizontal and vertical energy parks and by multiplication it is possible to achieve any power. Claims 1.
