Description

The invention relates to the field of wind energy, in particular to wind energy systems with a vertical axis of rotation of the wind wheel. These systems are designed to convert wind flow energy into electrical energy or thermal energy. In particular, these wind energy systems can also be located on the tower or on the roof of the house.

Known wind energy system according to patent US 7744338 (B2), publ. 2010.03.29, IPC 7 F03D 7/06, which contains the structure of the wind flow deviation (OPV), a wind wheel with a vertical axis of rotation, an energy converter that is connected to the wind wheel to convert the rotational movement of the wind wheel into useful energy, an orientation unit for the optimal direction of the OPV to wind wheel blades. In this case, on the front of the wind wheel, on one side, there is a convex structure of the wind flow deflecting externally and hollow from the inside onto the wind wheel blades. This structure covers the front part of the wind wheel, which mainly rotates in the opposite direction to the wind flow. And on the other hand and in front of the wind wheel there is an aerodynamic profile structure also for deflecting the wind flow on the wind wheel blades.

The main disadvantage of this wind energy system is the deviation of the wind flow on the blades of the wind wheel at different angles from the convex structure and from the structure of the aerodynamic profile for the deviation of the wind flow on the blades of the wind wheel. And this leads to a collision of deviated wind flows and turbulization of the resulting flow on the blades of the wind wheel and, as a result, this leads to a significant loss of energy flow on the blades of the wind wheel.

This drawback is also due to the implementation of the convex structure of the deviation of the wind flow in the form of a hollow outer surface, which open part faces the blades of the wind wheel. And this also leads to the circulation of the wind flow around the wind wheel and inside the indicated hollow convex structure, as a result of which there is also a collision of wind flows and their significant turbulization on the blades of the wind wheel. And this only increases the above disadvantage.

Closest to the solution that is claimed, on the technical nature and the technical result that is achieved, is the wind energy system according to patent US 7679209 (B2), publ. 2010.03.16, IPC 7 F03D 9/00, which contains the first structure of the wind flow deviation (OPV), the wind wheel with a vertical axis of rotation, means for fixing the wind wheel around and near the specified first structure of the OPV so that the wind wheel is driven by the deflected wind , an energy converter, which is connected to the wind wheel to convert the rotational movement of the wind wheel into useful electric energy, an orientation unit for the optimal direction of the OPV on the wind wheel blades. Moreover, in the wind energy system, the first structure of the wind flow deviation is made in the form of a vertically located cylinder, on two sides of which six cylindrical wind wheels are located on their vertical axes - three on each axis. The means of fixing the wind wheels around the specified first structure of the OPV (cylinder) are made in the form of upper and lower cross members, which connect the cylinder axis and the axis of the wind wheels from above and below the cylinder. The orientation unit for the optimal direction of the OPV on the blades of the wind wheel is made in the form of an electromechanical drive to rotate these crossbars perpendicular to the wind flow.

The advantage of the prototype in comparison with the analogue is a slight increase in the efficiency of using the wind flow due to the absence of a convex hollow structure of the deviation of the wind flow and the structure of the aerodynamic profile for the deviation of the wind flow on the blades of the wind wheel.

However, the main disadvantage of this wind energy system is also the deviation of the wind flow on the blades of the wind wheel at different angles from the first structure of the deviation of the wind flow in the form of a cylinder and from cylindrical wind wheels. And this also leads to the collision of deviated wind flows and turbulization of the resulting flow on the blades of the wind wheels. And, as a consequence, this also leads to a significant loss of wind flow energy on the blades of the wind wheel and a decrease in the efficiency of using the wind flow.

The basis of the invention is the task of increasing the efficiency of using the wind flow by directing the deflected wind flows in one direction.

The problem is solved in that the wind energy system contains the first structure of the deviation of the wind flow (OPV), made in the form of a body of rotation, a wind wheel with a vertical axis of rotation, a means of fixing the wind wheel around and near the specified first structure of the OPV in the form of upper and lower cross members so that the wind wheel led to the rotation of the first OPV structure by a deflected wind flow, an energy converter that is connected to the wind wheel to convert the rotational movement of the wind wheel into useful energy Ergyu, an orientation unit for the optimal direction of OPV on the blades of a wind wheel. Moreover, the wind energy system also contains a second OPV structure, which is located in front of the wind turbine and the first OPV structure so that the direction of the deflected wind flow by the outer surface of the second OPV structure coincides with the direction of the indicated deviation of the wind flow by the first OPV structure, while the wind wheel blades are located in the gap between the first structure of the OPV and the second structure of the OPV, the upper and lower cross members of the means for fixing the wind wheel on one side are rigidly connected to the blades rokolesa, on the other hand are connected to the vertical shaft of the vertical axis of rotation of the propeller, the second structure covers the front portion of OPV propeller that rotates generally opposite to the wind flow. And the specified external surface of the second OPV structure is made flexible to deflect strong wind flows from the wind wheel. In addition, the contour of the body of revolution of the first OPV structure in the plane of the vertical axis of rotation of the wind wheel follows the contour of rotation of the wind wheel and the contour of the inner surface of the second OPV structure. These blades of the wind wheel are rigidly connected to the specified first structure of the OPV for their simultaneous rotation around the vertical axis. Also, the indicated external surface of the second OPV structure can be made convex to the wind flow for the direction deflected by the wind flow to the blades of the wind wheel, and the inner surface of the specified second OPV structure is adjacent with a concentric gap to the wind wheel, while the said overlap in front of the wind wheel by the second OPV structure is predominantly is 120 degrees in the direction of rotation of the wind wheel from the perpendicular to the direction of movement of the wind flow. Also, the indicated outer surface of the second OPV structure can be made concave to the wind flow for the direction deflected by it, the wind flow to the blades of the wind wheel, and the inner surface of the specified second OPV structure is adjacent with a concentric gap to the wind wheel, while the specified overlap in front of the wind wheel by the second OPV structure mainly 90 degrees in the direction of rotation of the wind wheel from the perpendicular to the direction of movement of the wind flow. The specified second structure of the OPV with both a convex and a concave outer surface can be connected with the specified node orientation for the optimal direction of the specified deviation of the wind flow by the second structure of the OPV on the blades of the wind wheel. Top and bottom of the indicated first and second OPV structures can be located covers, which are respectively connected to the upper and lower parts of the second OPV structure and the specified orientation node. These covers can be positioned at an angle along the wind flow for the corresponding deviation of the wind flow up and down from the wind wheel and the first structure of the OPV.

The implementation of the wind energy system with a second structure of OPV, which is located in front of the wind wheel and the first structure of the OPV so that the direction of the deflected wind flow by the outer surface of the second structure of the OPV coincides with the direction of the specified deviation of the wind flow by the first structure of the OPV, avoiding the possibility of collision of the deflected wind flows from the first and second OPV structures. In addition, the location of the blades of the wind wheel in the gap between the first structure of the OPV and the second structure of the OPV allows you to create an ejection air channel in this gap. Moreover, the wind flow deflected by the second OPV structure, moving at high speed tangentially to the exit section of the ejection air channel, ejects air from it. And this ensures the movement of air in this ejection air channel in the direction of rotation of the blades of the wind wheel. Such a combination of two different air streams by ejecting one wind stream by another does not lead to their turbulization and the formation of vortices (energy loss). And this provides an increase in the efficiency of using the wind flow by selecting its greater power. To enhance the effect of the above on the outer surface of the first structure of the OPV can be additionally made protrusions, which can be located along the generatrix of this surface or at an angle.

The implementation of the upper and lower cross members of the fixation device of the wind wheel on one side of the wind wheel rigidly connected to the blades of the wind wheel and on the other side of the vertical axis of rotation of the wind wheel connected to the vertical shaft allows the wind wheel blades to be located along the entire height of the first OPV structure to ensure greater use of the wind deflected by the first and second OPV structures flow. In this case, the blades of the wind wheel are connected to the vertical shaft of the vertical axis of rotation of the wind wheel rigidly or through a bearing, ensuring the rotation of these wind wheel blades around the first structure of the OPV. At the same time, such a wind wheel is a type of Daria wind turbine.

The front overlap of the part of the wind wheel by the second OPV structure, which mainly rotates in the opposite direction to the wind flow, in conjunction with the above, also makes it possible to increase the use of wind flow energy by eliminating the counteraction of the wind flow to rotate the wind wheel.

The specified gap between the first structure of the OPV and the second structure of the OPV mainly made as a concentric gap. Also, this gap can be made with a narrower exit section and a correspondingly wider inlet section of the specified ejection air channel, which can occur when the first OPV structure is displaced in the horizontal plane.

Also, the profile of the blades of the wind wheel is mainly made in the form of a profile of the wing of the aircraft, located tangentially to the circumference of rotation of the wind wheel. And in another design, the profile of the blades of the wind wheel in the form of a profile of the wing of the aircraft can be made curved around the circumference of rotation of the wind wheel.

The implementation of the specified outer surface (or part of it) of the second OPV structure is flexible, which allows for the deviation of strong wind flows from the wind wheel due to the deflection of this surface.

Performing the contour of the body of revolution of the first OPV structure in the plane of the vertical axis of rotation of the wind wheel such that it follows the contour of rotation of the wind wheel, allows you to perform the shape of the first structure of the OPV and, accordingly, the shape of the wind wheel both in the form of a cylinder, and in the form of a cone-shaped, trapezoidal, barrel-shaped and the like. The contour of the inner surface of the second surface of the OPV also repeats the contour of the wind wheel in the vertical plane of its rotation.

The implementation of the wind energy system such that these blades of the wind wheel are rigidly connected to the specified first structure of the OPV, allows you to perform the system with simultaneous rotation around the vertical axis of both the wind wheel and the first structure of the OPV.

The implementation of the specified outer surface of the second structure of the OPV convex to the wind flow allows you to direct the deflected wind flow to the blades of the wind wheel. Moreover, the execution of the inner surface of the specified second OPV structure such that it adjoins the concentric gap to the wind wheel also makes it possible to create an ejection air channel in this gap in order to avoid turbulization of the resulting flow on the wind wheel blades and, as a result, also reduce a significant energy loss wind flow on the blades of a wind wheel. And it also provides improved wind flow efficiency.

The implementation of the specified overlap in front of the part of the wind turbine by the second convex OPV structure, mainly 120 degrees in the direction of rotation of the wind turbine from the perpendicular to the direction of the wind flow movement, allows to maximize the use of the deflected wind flows by the first and second OPV structures in combination with adding them to the ejected air flow in the gap between by these indicated structures. Moreover, within 90 ... 150 degrees of the specified overlap, this effect is maintained at a sufficient working level. If the specified overlap is more than 150 degrees, then this effect is progressively reduced due to the departure of part of the flow, deflected by the second convex-shaped OPV structure, beyond the limits of the wind wheel blades. If the specified overlap is less than 90 degrees, this effect is progressively reduced due to the deviation of part of the flow deflected by the second OPV structure into the gap between the first and second OPV structures, which counteracts the ejection of the air flow in this gap.

The specified external surface of the second OPV structure can also be made concave to the wind flow, which will also allow directing the wind flow deflected by it onto the blades of the wind wheel. Moreover, the execution of the inner surface of the specified second OPV structure such that it adjoins the concentric gap to the wind wheel also makes it possible to create an ejection air channel in this gap in order to avoid turbulization of the resulting flow on the wind wheel blades and, as a result, also reduce a significant energy loss wind flow on the blades of a wind wheel. And it also provides improved wind flow efficiency.

The implementation of the specified overlap in front of a part of the wind turbine by a second curved-shaped OPV structure predominantly 90 degrees in the direction of rotation of the wind-wheel from the perpendicular to the direction of movement of the wind flow makes it possible to maximize the use of deflected wind flows by the first and second OPV structures in combination with their addition to the ejected air flow in the gap between by these indicated structures. Moreover, within 60 ... 120 degrees of the specified overlap, this effect is maintained at a sufficient working level. If the specified overlap is more than 120 degrees, then this effect is progressively reduced due to the departure of a part of the flow deflected by the second concave-shaped OPV structure beyond the limits of the wind wheel blades. If the specified overlap is less than 60 degrees, this effect is progressively reduced due to the deviation of part of the flow deflected by the second OPV structure into the gap between the first and second OPV structures, which counteracts the ejection of the air flow in this gap.

The connection of the specified second structure of the OPV with both a convex and concave outer surface with the indicated orientation unit will allow to ensure the optimal (without turbulence of the deflected wind flows from the first and second OPV structures and without turbulization of the resulting flow on the wind wheel blades) direction of the specified deviation of the wind flow by the second structure OPV on the blades of a wind wheel.

The location above and below the specified first structure of the OPV covers also allows you to avoid turbulization of the wind flow above and below the first structure of the OPV due to the absence of penetration of the wind flow from above and below into the rotation zone of the blades of the wind wheel. At the same time, behind the covers, along the wind flow, a zone of reduced pressure appears, in which the wind flow is additionally sucked in front of the blades of the wind wheel, which also increases its speed.

The location of these covers at an angle along the wind flow will also avoid the turbulence of the wind flow above and below the wind wheel and the first structure of the OPV due to the direction of the wind flow, respectively, up and down from the upper and lower surfaces of the first structure of the OPV and the wind wheel. At the same time, behind the covers, along the wind flow, a zone of reduced pressure also appears, into which the wind flow is also additionally sucked in front of the blades of the wind wheel, which also increases its speed.

The above confirms the presence of causal relationships between the totality of the essential features of the claimed invention and the achieved technical result.

This set of essential features in comparison with the prototype of the wind energy system allows to increase the efficiency of using the wind flow by reversing the deflected wind flows from the first and second OPV structures in one direction - to the wind wheel blades. This eliminates the possibility of collision of deviated wind flows and excludes the possibility of turbulization of the resulting flow on the blades of a wind wheel.

According to the author, the claimed technical solution meets the criteria of the invention “novelty ″ and ″ inventive step ″ because the set of essential features that characterize the wind energy system is new and does not follow clearly from the prior art.

A preferred embodiment of the wind energy system in accordance with FIG. 1-3, is made with independent rotation of the wind wheel around the vertical axis 1. In this case, the wind energy system can be located on the tower or on the roof of the house (not shown). The wind energy system contains the first structure of the wind flow deviation (OPV), made in the form of a vertical cylinder 2, around which the rotor blades 3 rotate. The wind wheel contains fixation means in the form of upper 4 and lower 5 crossbars, which are rigidly connected on one side to the blades 3 of the wind wheel and, on the other hand, rigidly connected to the vertical shaft 6 with axis 1. The blades 3 are located around and close to the vertical cylinder 2 of the first structure OPV so that the wind wheel is driven into rotation by the deflected surface of the vertical cylinder 2 wind flow. The system also contains a second OPV structure, which is made in the form of a vertical structure 7 with a convex outer surface 8 to the wind flow for the direction deflected by it, the wind flow also to the blades 3 of the wind wheel, and the inner surface 9 of the specified vertical structure 7 is adjacent with a concentric gap of 10 to the blades 3 of the wind wheel and to the outer surface 11 of the vertical cylinder 2. The vertical structure 7 is located in front of the blades 3 of the wind wheel and the vertical cylinder 2 so that the direction is deflected of the wind flow with the convex outer surface 8 of the second OPV structure coincided with the direction of the indicated deviation of the wind flow by the outer surface 11 of the vertical cylinder 2 of the first OPV structure, while the vertical structure 7 of the second OPV structure overlaps part of the height of the wind turbine blades 3, which generally rotate counterclockwise wind flow. The specified overlap in front of the wind wheel is mainly 120 degrees in the direction of rotation of the wind wheel from the perpendicular to the direction of movement of the wind flow. The vertical structure 7 of the second OPV structure is connected to the orienting unit 12 for the optimal direction of the wind flow deflection to the blades 3 of the wind wheel, and through the upper 13 and lower 14 crossbars, respectively, is connected to the upper 15 and lower 16 ring bearings, which are mounted on a vertical shaft 6. Vertical cylinder 2 through the upper 17 and lower 18 crossbars, respectively, connected to the upper 19 and lower 20 bearings, which are mounted on a vertical shaft 6. From below, the shaft 6 is mounted on a rolling bearing 21, and through a gear 22 the shaft 6 is connected to the energy converter in the form of an electric generator 23 for converting the rotational movement of the wind wheel into useful energy. In accordance with FIG. 2, FIG. 5 and FIG. 10, covers 24 and 25 are located above and below said first OPV structure, which are respectively connected to the upper and lower parts of the second OPV structure in the form of a vertical structure 7 and said orientation unit 12. Said covers 24 and 25 are arranged at an angle along the wind flow for a corresponding deviation of the wind flow up and down from the wind wheel and the first OPV structure. And in the bottom cover 25 a hole is made for the shaft 6.

The crossbars 4, 5, 26, 27 are streamlined to reduce air resistance during rotation of the blades 3 of the wind wheel.

The blades 3 of the wind wheel can be connected to the vertical shaft 6 with the axis 1 by means of appropriate bearings (not shown) to ensure their rotation around the first OPV structure. In this case, the rotation of the wind wheel through an intermediate hollow shaft (not shown), which is rigidly connected to one of the ends of the cross members of the wind wheel, is transmitted to the transmission 22 of the energy converter.

In one embodiment, in accordance with FIG. 4-6, the wind power system with the rotation of the wind wheel around the vertical axis is made with blades 3 of the wind wheel, which are rigidly connected by the upper 26 and lower 27 crossbars to the first OPV structure in the form of a vertical cylinder 2 and simultaneously rotate with it around the vertical axis 1. At the same time, the vertical cylinder 2 can serve as a flywheel.

Also in one embodiment, in accordance with FIG. 7, the wind energy system is made with a flexible convex outer surface 28 of the second OPV structure for deviating strong wind flows from the wind wheel.

Also in one embodiment, in accordance with FIG. 8, the wind energy system is made with the outer surface 29 of the second OPV structure concave to the wind flow for directing the deflected wind flow to the wind turbine blades 3, and the inner surface 30 of the second OPV structure is adjacent with a concentric gap 10 to the wind turbine blades 3 and to the outer surface 11 of the vertical cylinder 2.

According to the example shown in FIG. 11, for the deviation of strong wind flows from the specified wind energy system, the second OPV structure can be performed with a mechanical system of this deviation in the form of the elastic displacement of the wind flow force sensor 31 (the displaced part of the outer surface of the second OPV structure). The sensor 31 biases the first gear rack 32, the displacement of which is transmitted through the gear wheel 33 to the second gear rack 34 with a sliding plate 35 (for the outer surface of the second OPV structure) to deflect a strong wind flow.

The gear 22, which connects the shaft 6 to the power converter, can be made by a pulley, gear and the like. Moreover, as a power transducer of the rotational movement of the shaft 6 into useful energy, a transducer into thermal energy can also be used, for example, in the form of a well-known cavitation generator.

In other embodiments, in the wind energy system, the first structure of the OPV is made in the form of a body of revolution, the contour of which in the plane of the vertical axis of rotation of the wind wheel repeats the contour of rotation of the wind wheel and the contour of the inner surface of the second structure of the OPV.

Wind power system with independent rotation of the wind wheel around the vertical axis works as follows.

The wind flow, which is indicated by the arrows in FIG. 2, 3, 5, 6, 7, 9, and 11 act on the orientation unit 12 with a speed V1, which forces the second OPV structure in the form of a vertical structure 7 to turn its outer surface 8 towards the wind flow. Further, the wind flow with acceleration flows around the outer surface 8 of the vertical structure 7. And this already accelerated wind flow further goes to the outer surface 11 of the vertical cylinder 2, flows around it with additional acceleration and already at a speed V2, which is greater than the speed V1, acts on the blades 3 wind wheels with more powerful force than the initial wind flow. The wind wheel rotates the shaft 6, which, through the transmission 22, rotates the energy converter in the form of an electric generator 23 to generate useful electricity. In this case, the blades 3 of the wind wheel rotate independently and the entire power of their rotation is directly applied to the rotation of the electric generator 23.

In an embodiment of a wind energy system in accordance with FIG. 4-6, the rotation of the wind wheel around the vertical axis 1 is carried out simultaneously with the rotation of the vertical cylinder 2, which additionally speeds up the wind flow and performs the function of a flywheel.

Although shown and described as being the best for carrying out the present invention, those skilled in the art will understand that various changes and modifications can be made and elements can be replaced with equivalent ones without departing from the scope of the present invention. In particular, terms such as ″ first ″, ″ second ″ are given in the present application for convenience reasons and are not terms that limit the scope of rights in the application. The term ″ appropriate ″ should be understood as the upper element of the system is associated with another upper element, the lower - with the second lower element and the like.

The compliance of the proposed technical solution with the criteria of the invention ″ industrial applicability ″ is confirmed by the indicated examples of the wind energy system.
