Since the claimed method of converting wind energy is implemented with the device, its detailed description, see the corresponding description of the operation of the device.

A device for converting wind energy (figure 1) contains plates 1 and 2 performed the s tapering and extending along the first incident flow S and intended to be formed in the region of the narrowing of the plates 1 and 2 zones V reduced pressure. The pipe 3 is designed to transmit the second air flow F. One end of the pipe 3 is made open and connected with the surrounding space. The other end communicated with the outer surface of the aerodynamic surface) of one of the plates, for example with the aerodynamic surface of the plate 1 in the area of narrowing of the plates 1 and 2. The Converter 4 is installed in the pipe 3. In the area of narrowing of the plates 1 and 2, at least one of the plates, for example plate 1 made with a cavity 5 for the attachment of the second air flow F. the Cavity 5 communicates with the pipe 3. The cavity 5 is made orthogonal to the direction of the first incident flow S with the possibility of twisting of the second air flow F on a tangent direction of the first incident flow S.

The cavity 5 is cylindrical (Fig 1, 2) or conical (figure 1, 2 is not shown) and is associated with narrowing of the plates 1 and 2 through the slot 6, is made in the plate 1.

The open end of the pipe 3 provided with a vent 7 (3), made with the possibility of twisting of the second air flow F with respect to the longitudinal axis of the pipeline 3.

The inlet 7 may be performed with an internal conical surface, provided with blades 8 (4, 13)mounted at an angle to the longitudinal axis of the air is of sabornie 7.

The inlet 7 may be performed with the internal conical surface in which the spiral groove 9 (Fig).

The cavity 5 for the attachment of the second air flow F (figure 5) can be performed in the other plate 2.

In the device can be entered an additional Converter 10 (6), which is set immediately before the area of low pressure along the first incident flow S.

In the device can be entered an additional Converter 10 (7), which is installed immediately behind the area of low pressure along the first incident flow S.

The device can be entered two additional plates 11 and 12 (Fig), which is made tapering and extending along the first incident flow S for forming between them a zone of reduced pressure. Additional plates 11 and 12 are identical aerodynamic surfaces of the plates 1 and 2 (figure 1)and spatially located relative to them perpendicular. On the sides of the additional plates 11 and 12 are connected to the two plates 1 and 2 for the formation of cell 13 (Fig).

The cavity 5 can be respectively performed in each of the four plates 1, 2, 11, 12 cell 13.

The system can be used multiple cells 13. Identical cells are located close to each other in rticula and/or horizontal row (Fig.9). Adjacent plates 1, 2, 11, 12 adjacent cells 13 are connected with the formation inside the camera 14 (figure 10). During the second air flow F the pipe 3 when the Converter 4 are branched. The branched ends of the segments 15 of the pipeline 3, respectively connected at least to one of the aerodynamic surfaces of the plates 1 or 2 or 11 or 12 of each cell 13 (figure 10 branched ends of the segments 15 of the pipe 3 is shown in dashed lines connected to the narrowing of the plates 1 or 2 or 11 or 12 of each cell 13).

The branched ends of the segments 15 of the pipeline can be made of hoses (flexible), cylindrical or conical shape, located in the chambers 14 of the cell 13.

The optional Converter 10 (figure 10) can be installed in the chamber 14 for each or some of the cells 13.

The system can be entered cutter 16 of the first incident flow S (11, 12). The cutter 16 is made V-shaped and reversed its direction towards the first oncoming air stream S. the Cutter 16 has, at least along one extreme number of cells 13, for example, immediately below them. The inlet 7 is installed along the first incident flow S for the cutter 16.

A device (1) as follows.

The first air flow S passes between DV is me narrowing and expanding on his turn the aerodynamic surfaces of the plates 1 and 2 for forming between them in the field narrowing of the aerodynamic surfaces of zone V reduced pressure. The second air flow F is passed via line 3 in zone V reduced pressure. On the path of the second air flow set F Converter 4. In zone V of reduced pressure, in at least one of the plates 1 perform the cavity 5, which provides the twisting of the second air flow F of the wall of this cavity 5. The twisting of the second air flow F is formed tangentially in the direction of the first incident flow S.

The twisting of the second air flow F can be implemented by various means. Without the introduction of any additional elements by passing the second air flow F through the pipeline 3 and hit him in the cavity 5 (like a spinning funnel formed by draining water from the tank through the outlet). The twisting of the second air flow F can be performed directly by the rotation of the rotor blades of the turbine of the Converter 4. Due to the spiral arrangement of the various elements, such as blades inside of the pipe 3 (Fig 3, 4, 13) or run inside a pipeline 3 spiral grooves (Fig), or perform the corresponding elements in the air intake 7 (Fig 3, 4, 13, 14). The cavity 5 may be made cylindrical (Fig 1, 2) or conical (figure 1, 2 is not shown) and is associated with narrowing of the plates 1 and 2 cher the C slot 6, made in the plate 1. The cavity 5 of the conical shape is useful when the cavity 5 of the plates 1 and 2 are shorted together.

The first air flow S (1), getting on tapered aerodynamic surface plates 1 and 2, increases the speed which is maximum in zone V of low pressure, especially in the boundary layer. Zone V is fed via line 3 to the air from the environment, spiral twisted tangent to the direction of movement of the first oncoming air stream S. In contrast to analogues in which the second air flow F is served orthogonal to the first air flow S, which increases the total aerodynamic resistance in the interaction of these flows, in the proposed method when tightening the second air flow F on a tangent in the direction of the first incident flow S is the coincidence of the directions of rolling zone V streams and the resulting cascading from zone V stream. Zone V is the effective suction of the second air flow F with decreasing aerodynamic drag. This allows to significantly reduce the aerodynamic resistance in comparison with analogues.

Because the second air flow F with a small resistance is served through a separate pipeline 3 from OCD the global environment (from the zone of atmospheric pressure) in zone V reduced pressure (prevacuum), the inverter 4 most efficiently converts the energy of the second air flow F into mechanical energy of rotation of the blades of the turbine rotor and respectively into electrical energy.

The second air flow F through the inlet 7 (3), installed in front of the Converter 4, are formed by the spiral. This increases the efficiency impacts of the second air flow F on the rotor blades of the turbine of the Converter 4 and thereby produce additional training the introduction of the second air flow F in the cavity 5.

In addition, the second air flow F in front of the transducer 4 may be twisted along the second air flow in the pipe 3 by a narrowing spiral (figure 5) using the intake 7 (Fig, 14). In place of the narrow pipe 3 sets of rotor blades of the turbine of the Converter 4, because the second air flow F in the narrowing place gets increased speed.

The cavity 5 is additionally performed in zone V of the reduced pressure in the other plate 2 (figure 5). Additionally provide the twisting of the second air flow wall of this cavity 5. This twisting of the second air stream also forms a tangent to the direction of passage of the first oncoming air stream S. due to this additionally reduces the resistance as the speed is, I can pay tithing incident flow's maximum in the border layer of the airfoil. The cavity 5 in the other plate 2 is also connected to the inverter 4 (figure 5 are not shown).

In the device can be entered an additional Converter 10 (6), which is installed during the first incident flow S immediately before the zone V reduced pressure. The introduction of an additional transducer 10 increases the resistance of the first oncoming air stream S, but also allows us to get some energy. The arrangement of the rotor blades of the turbine of the Converter 4 out of zone V allows increasing the aerodynamic drag of the interaction of the first incident flow S and the second air flow F. Additional Converter 10 may also be installed during the first incident flow S just outside the area V reduced pressure (7), i.e. in the place where the velocity of the first oncoming air stream S is close to the maximum.

Similarly, the technical solution according to U.S. patent No. 4079264 it is advisable to increase the converted power to use multiple cells 13.

To do this, enter two additional plates 11, 12 (Fig)that perform the narrowing and widening in the course of the first incident flow S for formation between zones V reduced pressure. Complete the performance communications of the plate 11, 12 on each side closes with the two plates 1 and 2, thereby forming a single cell 13.

Similarly for the formation of cavities in the two plates 1 and 2 (figure 5, 6) in each of the four plates 1, 2, 11, 12 perform cavity 5 (figure 10), which ensures the twisting of the second air flow F the walls of these cavities 5. The twisting of the second air flow F in each of the four cavities 5 formed tangentially in the direction of the first incident flow S.

The system uses multiple cells 13 (Fig). Plates 1, 2, 11, 12 cells 13 are connected in the vertical and/or horizontal row (Fig.9) with the formation of the inside of the adjacent plates of adjacent cells 13 closed cavity chamber 14 (figure 10). During the second air flow F the pipe 3 when the Converter 4 performs extensive. Branched segments 15 of the pipeline 3 (11), respectively fail, at least one of the aerodynamic surfaces of the plates of each cell 13. Unlike the nearest analogue of the cells 13 have on the plane without free spaces between them and the chamber 14 between the cells 13 are used to strip the branched segments 15 of the pipeline 3 (11), for installation in closed cavities 14 buildings additional converters 10 (figure 10), etc. For laying branched segments 15 in the walls of the Ah chambers 14 on the leeward side of the first flow S made holes, through which pass the branched segments 15 of the pipeline 3 (figure 10). For installation in the camera housing 14 additional Converter 10 and the output shaft in the space of the first flow S in the wall of the chamber 14 also made a hole for the output shaft of the additional transducer 10 (figure 10). Forming the external shape of the cells 13 in place of the clamping plates 1, 2, 11, 12 can be approximated (like the shape of the wing) to the aerodynamic surface with minimal frontal resistance to the first oncoming air stream S. due to the location of the cells 13 in a continuous series with the implementation of the cameras 14 it is possible to reduce the resistance of the whole structure to the first oncoming wind flow, to increase the power Converter 4 relative to the construction area; to increase the efficiency of the device and to reduce the overall dimensions and weight.

In addition, the system can be introduced cutter 16 of the first oncoming air stream S. the Cutter 16 is turned to its angle towards the first oncoming air stream S (11, 12), so for them a zone of high pressure (the air flow rate in this area is minimal). The inlet 7 is set as the first incident flow S for the cutter 16. By ispolzovaniya 16 can increase the pressure drop between the inlet pipe 3 and the output of the cavity 5, consequently, in addition to increase the capacity of the inverter 4. In addition, the cutter 16 can reduce wind load on the public portion of the pipe 3 and in addition to send the bottom of the first air flow S in the area of the bottom row of cells 13. In addition, the cutter 16 and the air inlet 7 can be located around the perimeter of the structure.

FIELD: electrical engineering.

SUBSTANCE: invention relates to on-coming energy converters used in wind-power engineering, hydraulic power engineering and instruments. In proposed method two physical are used simultaneously, namely, self-excited oscillations and electromagnetic induction. Conversion of energy of on coming flow is provided due to electromagnetic induction appearing at self-excited oscillations in metal strings (flexible conductors) arranged in on-coming flow and placed in magnetic field. According to law of electromagnetic induction, metal string executing oscillatory movements in magnetic field becomes electric energy (current) generator.

EFFECT: increased power output of converter by increasing number of strings to required value.
