Description

[0001] A WIND TURBINE

[0002] FIELD OF INVENTION

[0003] The invention relates to a wind turbine for the generation of electricity by utilizing wind energy.

[0004] BACKGROUND OF THE INVENTION

[0005] The use of resources such as solar and wind for electricity generation is increasing today. Horizontal and vertical wind turbines are designed according to the way the propeller is positioned to utilize wind energy.

[0006] Vertical wind turbines are usually mounted on towers and installed in areas where wind speeds are higher. Vertical wind turbines can operate efficiently even at low wind speeds, but are most efficient in locations with strong and sustained winds. They are suitable for commercial and industrial electricity generation and can be integrated into the grid. They are generally used in onshore and offshore wind farms. Turbine blades are aerodynamically designed and convert the kinetic energy of the wind into mechanical energy and then into electrical energy.

[0007] Horizontal wind turbines are one of the most widely used turbine types for generating electricity from wind energy. In these turbines, the propeller consists of three or more blades attached to a rotating vertical shaft. Routing devices are also used to gain benefits when the wind comes from different directions. In these cases, the wind coming in a direction perpendicular to the propeller blades affects the performance. Therefore, it is necessary to obtain a linear flow in the routing devices.

[0008] As a result, all the above-mentioned problems have made it imperative to innovate in the relevant technical field.SUMMARY OF THE INVENTION

[0009] The present invention relates to a wind turbine to overcome the aforementioned disadvantages and to bring new advantages to the relevant technical field.

[0010] The aim of the invention is to provide a wind turbine with increased efficiency.

[0011] In order to accomplish all of the aforementioned objects and those which will arise from the following detailed description, the present invention relates to a wind turbine having a carrier body and a propeller provided in a horizontal position in an upper body positioned on said carrier body, and at least two routing walls for directing wind to said propeller. Accordingly, each of the mentioned routing walls extends from the outer wall of the upper body to a wind exit plane defined in the neighborhood of the propeller. Thus, the wind that enters between the routing walls does not mix with the wind passing between the neighboring routing walls and reaches the propeller. No mixing of flows prevents the formation of vortex. Therefore, efficiency is increased by obtaining a linear flow up to the propeller.

[0012] In another preferred embodiment of the subject matter invention, the wind exit plane is parallel to the propeller. Thus, the wind reaches the propeller perpendicularly.

[0013] In another preferred embodiment of the subject matter invention, the routing walls are provided in the form of interlocking truncated cones and are hollow inside.

[0014] In another preferred embodiment of the subject matter invention, the outer perimeter of the routing walls is provided in concave form.

[0015] In another preferred embodiment of the subject matter invention, a flow channel defined between two adjacent interlocking routing walls is provided in a narrowing cross-section.In another preferred embodiment of the subject matter invention, there is provided at least one connecting wall extending in the direction of the central axis of the upper body for connecting the directional walls to each other.

[0020] DETAILED DESCRIPTION OF THE PROBABLE EMBODIMENT(S)

[0021] In this detailed description, wind turbine (10) is explained with references to examples without forming any restrictive effect in order to make the subject more understandable.

[0022] The present invention wind turbine (10) essentially comprises a carrier body (20) and an upper body (30) positioned on said carrier body (20). The said carrier body (20) can be configured in different ways, and in an exemplary configuration, it is obtained by joining metal profiles. The carrier body (20) enables the upper body (30) to be transported and held in a stable position.

[0023] There is a propeller (70) provided on the upper body (30). The propeller (70) has a horizontally positioned propeller (70) configured to rotate about a central axis (a) extending in a direction substantially perpendicular to the ground.

[0024] The upper body (30) is basically obtained by joining at least two routing walls (31). In the present invention wind turbine (10), the routing walls (31) are provided in the form of a truncated cone. Each routing wall (31) is provided hollow and the upperbody (30) is obtained by interlocking arrangement of at least two routing walls (31). At least one connecting wall (50) is provided to connect the routing walls (31) to each other. The said connecting wall (50) extends essentially in the direction of the central axis (a). In the present invention wind turbine (10), the outer walls of the routing walls (31) are provided in concave form. When the two routing walls (31) are positioned one inside the other, the space between them forms a flow channel (40). In the present invention wind turbine (10), each of the routing walls (31) extends from the outer wall of the upper body (30) to a wind exit plane (43) defined in the neighborhood of the blade. The said wind exit plane (43) runs essentially parallel to the propeller (70). In other words, each routing wall (31) has a first diameter (32) on the wind entry side and a second diameter (33) on the wind exit plane (43) side. The first diameter (32) is larger than the second diameter (33). In a possible embodiment of the invention, the flow channel (40) is provided in a narrowing cross-section from an inlet opening (41) into which wind enters to an outlet opening (42) from which wind exits.

[0025] The propeller (70) is located at the top of the upper body (30). There is a side wall (60) surrounding the outer wall of the propeller (70). The side wall (60) extends upwards from the end of the outermost routing wall (31) on the side of the inlet opening (41) and prevents wind from entering the propeller (70) from this part.

[0026] In the present invention wind turbine (10), the wind coming from the sides and bottom of the upper body (30) enters the flow channel (40) through the inlet openings (41). With the concave form of the routing wall (31), the wind changes direction and comes essentially perpendicular to the propeller (70). Each routing wall (31) extends to the wind exit plane (43) so that the wind in different flow channels (40) is carried as close as possible to the propeller (70) without mixing with each other. Therefore, although the wind is carried at different speeds in the flow channels (40), since they do not mix with each other, the formation of a vortex that would adversely affect the flow is prevented. By providing the flow channels (40) in a narrowing cross-section, the flow rate is increased. In addition, the side wall (60) prevents the wind from entering through the flow channels (40), which would distort the direction of the wind.The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments in the light of the foregoing disclosures, without departing from the main principles of the present invention.REFERENCE NUMBERS
