Description

Hi-power generating vortex windmill wing

The present invention is a high-powered one-piece rotating structure installed in the multi-stage structure in the first half of the multi-stage structure is fixed by the excitation force of the three-dimensional three-dimensional vortex outflow between the two cross-crossing structure at a predetermined interval It is about power vortex wind vane.

In general, wind power generation converts kinetic energy caused by air into mechanical energy by rotating windmills using aerodynamic characteristics, and generates electricity using this mechanical energy. The horizontal axis forms according to the direction of the rotation axis with respect to the ground. Propeller-type windmill (wind power generator: Patent registration No. 10-1027055, registered on March 29, 2011) is mainly used, and it is widely used from connecting to large-scale power system to independent small power sources such as remote islands or mountain wall. Since wind power varies greatly in time, when used as an independent power source, it is used in combination with a storage device such as charging with a battery or other power generation methods. Among the windmills applied to such wind generators, propeller type windmills, which are known as the best windmills at present, are used for propeller blades having a length of 10 m to 50 m in large cases. Since the air resistance increases and the rotational speed decreases, the form of increasing the rotational speed by thinning the tip of the blade in terms of rotational efficiency has been mainstream, and three or four blades are operated in the radially coupled form at the tip of the power generation unit. However, when the wind speed is small, the windmill may not rotate smoothly due to the resistance, and does not rotate at all about 3m / s or less. When the wind is about 25m / s or more, the propeller breakage occurs, so the rotation of the propeller is prevented by turning the blade angle of the propeller to stop the rotation. And when the propeller blades of this structure rotates, a lot of noise is generated, environmental problems due to the large-scale construction of the foundation according to the installation amount of power generation has appeared as a big problem.

(Relationship between Circumferential Wing and Wake Ring According to the Present Invention)

In general, propeller windmills are rotated by a windmill vane with a welcome angle (tilt angle) in the wind direction, and generate electric power by this turning force. However, if the circumference with no welcome angle in the wind direction is installed as a wing (hereinafter referred to as 'circle wing') (for example, the circumferential wing of FIG. 1), Karman Vortex occurs in the wake of the circumferential wing, and the circumferential wing is perpendicular to the flow. It does not rotate, but does not occur, but cross the circumference of the circumference of the structure (circle, square, polygon, etc. in the form of a ring, hereinafter referred to as a 'waring ring') as shown in Fig. By adjusting the spacing, it was found that the circumferential blade rotates at a specific spacing. This is because the excitation force of the vortex flowing out between the circumferential blade and the wake ring acts oppositely on both sides of the rotary blade to generate the rotational force.

The circumference of the circumference turns into a wing by the circumference of the circumference with the circumference of the circumference of the circumference of the circumference which has no welcome angle at all, which is sucked by the three-dimensional vortex while forming a three-dimensional vortex near the intersection in FIG. It can be seen that the flow is due to the pulling force pulling the circumferential blade (wing).

1 is a vortex windmill in the case where two rotating circumferential vanes according to the present invention are used. Where W is the wake ring width, D is the ring center diameter, s is the spacing between the circumferential wings and the wake ring, and d is the diameter of the circumferential wing. 2 is a vortex windmill diagram in the case of using four rotating cylinder wings in accordance with the present invention. 3 is a diagram comparing the rotation speeds at the same wind speed when the circumferential wings are set to 2, 4 or 8 sheets. Here, the blade length is L = 60mm, the gap ratio is s / d = 0.35, and the ring width ratio is W / d = 1.0. In FIG. 3, the rotational speed is 2 times 106 rotations at 4 wind speeds and the rotation speed is 4 times at 168 rotations, and the rotation speeds are 8 at 230 wind speeds. 588 times in Esau and 806 results in 8 sheets. This means that the more circumferential wings at the same wind speed, the higher the number of revolutions.

4 is a diagram comparing the amount of power generation between a one-stage vortex windmill (one circumferential wing and one wake ring) and a conventional propeller windmill. Here, the vortex windmill with one ring in the wake of the circumferential wing shows that the total power generation is larger than that of the small- and medium-sized propeller windmills, but less than 25 m / s is smaller than the large propeller windmills. However, even if the circumferential wing rotates even more than 25m / s, the total power generation is never less than the large windmill. In the small and medium windmills, the wind speed stops at about 13 m / s because of the lack of pitch control due to economic efficiency, and at 25 m / s or more in the large propeller windmills. This is called cut off wind speed.

(Example of the present invention)

In the vortex wind vane of the present invention, the rotational speed of the circumference of the circumference increases linearly with the wind speed, whereas the large propeller windmill stops the windmill operation due to the problem of propeller breakage at a high speed of 25 m / s or more, the vortex windmill is 30 m / Above s, the excitation forces of the vortex flowing out between the circumferential wing and the wake ring structure act symmetrically with each other and have a large rotational force. In the case of propeller windmills at high wind speeds, the thin parts of the propeller windmills fail to withstand the wind, while the windmill wings are circumferential, even though the powerful wind acts on the wings, the power is distributed throughout the circumference, reducing the risk of breakage. The vortex wind vane has a low frequency of vortices occurring at the wake of the circumference of the circumference, and at the main speed ratio that represents the ratio between the wind speed and the rotational speed of the vane, it is less than 1/6 of the existing propeller windmill, so it rotates at that low speed. This is less and has an advantage for the stability of the rotor blades at low speed rotation. This is the same result when the columnar wing is a columnar body (a column of polygons including a rectangle).

The vortex windmill vane of the present invention having the above characteristics solves the problem of the existing propeller windmill blades by solving the noise problem caused by the high-speed rotation, the torque is more than 10 times stronger than the existing propeller, and the generation amount is also very large eco-friendly windmill solves the disadvantages of the existing windmill It is to provide high-efficiency energy means in the era of nuclear power plants. In the case of a singular ring having one wake ring, comparing the relationship in FIG. 3 where the number of rotations of the circumferential wing is 2 and the number of the 4 and 8 sheets, the circumferential wing and the wake ring are There are two places of intersection, and eight places with four circumferential wings, and sixteen with eight circumferential wings. Therefore, the number of rotations is 1.6 times more in the case of 4 pieces than in case of 2 circumferential wings, and 2.2 times more in the case of 8 circumference wings.

The larger the number of circumferential blades, the greater the rotational force, the greater the excitation force, the greater the torque and the greater the amount of power generated. Therefore, it can be seen that the amount of power generated increases if the circumferential wing is installed more as needed. However, in the case of installing one wake ring and arranging the circumferential wings accordingly, the number of circumferential wings is limited due to the proper spacing between the circumferential wings due to the mutual influence of the three-dimensional vortices occurring at the intersection.

In the present invention, in order to overcome the limitations and obtain a method for installing more circumferential wings, first, by examining the range that the three-dimensional vortices are generated to influence the vortices mutually, the circumferential wings at intervals outside the range of bad influences To install. The vortices affected by other flows should be considered for this badly affected area because they are not regular and cause crushed vortices and thereby weaken the aftershocks. In order to investigate the range of influence on the flow of three-dimensional vortices occurring near the cross section of the circumferential wing crossing the cross, the flow field was first visualized to investigate the flow field size, and the flow velocity of the whole wake flow field was measured with a flowmeter.

First, a smoke wire visualization method was used to generate smoke upstream of the circumference of the circumference. FIG. 5 (a) is a sketch of the visualization of the three-dimensional vortex flow occurring near the intersection of the circumferential wing crossings. In order to measure the influence range of the vortices acting on the surface of the circumferential wing, that is, the three-dimensional vortex flow occurring near the intersection, in the direction of the circumference of the circumferential wing (y-axis), oil is applied to the thin film film and the circumferential wing It is a visualized photograph of the film spreading out after a certain time by attaching it to the flow field. 5 (b) is a visualized photograph of the vortex generation flow of the circumferential wing surface by the oil film method. Where α is the spread angle of the oil film, s is the distance between the circumferential wing and the wake ring, and d is the diameter of the circumferential wing.

As shown in Fig. 5 (a), the effect of the vortex periodically generated as shown in Fig. 5 (a) on the y-axis direction in the circumferential wing direction is investigated by the wake ring provided in the wake of the circumferential wing. In the photograph, when the two structures are attached to each other, i) s / d = 0, the surface flow of the circumferential blade is in the range of y / d = 0 corresponding to ① to about y / d = 1.7 corresponding to ② It can be seen that there is little effect between ②y / d = 1.7 and ③y / d = 3.5, but if ③y / d = 3.5 or more, it has a constant width without any effect and y / d = 0 It is symmetrical on both sides.

This indicates that vortices occur periodically in a symmetrical form on both sides about y / d = 0. The upstream circumferential wing wake structure is slightly spaced apart, showing a different appearance from i) s / d = 0 for ii) s / d = 0.35. Looking at the surface flow of the circumferential blade, it can be seen that it affects the range of y / d = 0 corresponding to ④ to about y / d = 1.5 corresponding to ⑤, and y / d = corresponding to between ⑤ and ⑥. There is little impact between 1.5 and 3.5. Since y / d = 3.5, there is no effect at all and it has a constant width.

iii) In the case of the circumferential wing alone with no circumferential ring in the wake of the s / d = ∞, the entire circumference of the circumferential wing has the same width as ⑦. It has the same width as the flow of position completely out of the influence of vortex caused by the wake ring like ③ and ⑥. In the above results, when cross-flowing the wake ring at the circumference of the circumferential wing, the influence range of the vortices occurring near the cross-crossing part is partially influenced from the minimum y / d = 1.5 to the maximum y / d = 3.5 at s / d = 0.35. It can be judged to have. Similar trends are shown in the case of s / d = 0.5 at the circumferential wing and the wake ring spacing s / d = 0.35 to 0.5 shown in the present invention.

The circumferential wings and the downstream ring by a cross in cross-section in which a fixed state to the hot-wire flow meter with respect to the influence range of the vortex flow in the circumferential wing wake circumferential blade wake flow velocity of the whole as described above were examined. FIG. 6 shows an average velocity distribution of the flow space field in the z-axis direction, which is perpendicular to the wake flow direction, and in the horizontal and right-angle direction (y-axis direction, which is the axial direction of the circumference of the wing). That is, the three-dimensional vortices generated near the intersections in the state where the circumferential wing and the wake ring cross each other show the range influencing the flow in the z-axis direction and the y-axis direction.

In Fig. 6, the circumferential wing and the wake ring cross each other, and the circumferential wing diameter d and the wake ring width W are 26 mm, the distance between the circumference wing and the wake ring s / d = 0.35, the flow rate U is 0.5 m / s, and the flow velocity of the flow field. The position of the probe to be measured is x / d = 2.0, y / d = 1.0 to 6.0 and z / d = + 4.0 to -4.0. Here, the x-axis direction is the flow direction of the circumferential wing wake. In other words, a hot wire flowmeter was installed in the wake about twice the diameter of the circumferential blade and the average flow velocity distribution in the y-axis direction and z-axis direction was investigated. Where x is the distance in the flow direction, y is the axial distance in the circumferential wing, z is the distance perpendicular to the flow, d is the diameter of the circumferential wing, and W is the width of the wake ring.

First, in the case of y / d = 1.0, the flows of the circumferential wing and the wake ring wake show that the average flow rate value U / U between z / d = 4.0 and z / d = -4.0 shows a value between 1.0 and 1.5. It is relatively affected inside of ② and ③ where / d is within ± 1.5. After that, the z / d values up to ± 3.5 show some inclination values in the ① and ④ ranges. This can be seen in comparison with y / d = 4.0 and y / d = 6.0, which are outside the influence range of vortex generation. This shows a similar trend in y / d = 1.5 and y / d = 2.0. At y / d = 3.0, the effect of vortex generation is less, and there is a similar trend when compared within ⑤, ⑥, ⑦, ⑧ range of y / d = 4.0 and y / d = 6.0, but z / d = 1.0 at z / d A slight difference can be seen by comparing the mean flow rate values between d = 1.5. Although y / d = 3.5 is missing in the drawing of the experimental results, it showed a tendency similar to y / d = 3.0.

In the results of FIGS. 5 and 6, which closely examine the extent to which the three-dimensional vortex affects the entire flow field, the vortices occurring between the two structures are circumferential wing diameter 1.5 in the circumferential wing axis y of the right and left directions of the flow. It can be concluded that the effect is between 3.5 and 3.5 times, and also between 1.5 and 3.5 times the diameter of the circumferential wing in the z-axis direction of the vertical direction of the flow. From the above conclusions, the proper spacing between the circumferential wing and the circumferential wing of each stage of the vortex wind vane wing is at least 1.5 times the vortex influence (1.0 times the diameter of the circumferential wing diameter 0.5 times), and the effect of the vortex effect. The maximum range is 3.5 times (3.0 times plus the circumferential blade diameter radius 0.5 times).

In other words, the vortex generation has a large effect within 1.5 times the diameter of the circumference, the effect is gradually reduced over the range, there is no effect at 3.5 times or more. Therefore, it must be spaced apart from this section so that the excitation force due to vortex generation can be obtained as much as possible. However, even when the boundary edge fence is installed to absorb or block the influence of the vortex, the circumferential wing can be installed by narrowing the diameter of the circumferential wing to 1.5 times, allowing more circumferential wings to be installed. Also, in the wake ring, the wake ring is a wake structure that crosses the circumference of the circumference, so that the distance between the wake ring and the wake ring in FIGS. 5 and 6 affects the width of the wake ring between 1.5 and 3.5 times the width of the wake ring. . Therefore, in consideration of this range, the wake rings are concentrically Must be installed.

More specifically, as a result of measuring the range y / d (y: circumferential wing axial distance, d: circumferential wing diameter) of the three-dimensional vortex generated between the circumferential wing and the wake ring structure in the circumferential wing axis direction, FIG. As shown in the figure, the effect is significantly less than 1.5 times the diameter of the structure.

At the same time, not the circumferential wing surface but the circumferential wing and the wake ring The effect on the space field of the flow between them is fixed with the spacing between the circumferential wing and the wake ring s / d = 0.35 (s = the spacing between the circumference wing and the wake ring, d: diameter of the circumferential wing) and heating probe In FIG. 6, the flow velocity distribution of the flow field around two structures is measured while moving the In the vertical direction z-axis direction (although there is a slight difference), the effect is large at 1.5 times or less of the circumference of the circumference, but the effect is less between the range of 1.5 times to 3.5 times. Therefore, the circumferential wings are arranged in consideration of minimizing mutual interference of vortices. Therefore, the spacing between the circumferential wing and the wake ring should be arranged to have a spacing of 1.5 times to 3.5 times the diameter of the minimum circumferential wing or the wake ring.

Similarly, when the wake ring is installed in multiple stages, vortices are also influenced between the first stage wake ring and the second stage wake ring, so that the boundary membrane edge fences can be installed to block the effects of the vortex.

In the above, the distance between the circumferential wing and the circumferential wing (1 in Fig. 11) is 7.0 times the diameter of the circumferential wing (maximum range 3.0 times × 2 (both sides) = 6.0 times in consideration of the two circumferential wing directions). Circumferential wing diameter 1 times (0.5 × 2) plus 7 times, hereinafter description not given below At least 3.0 times (minimum range of vortex influence 1.0 times × 2 (both sides) = 2.0 times) 2) plus 3.0 times, the description below will be provided at intervals or more, and the gap between the boundary membrane edge fence and the edge fence (2 in Fig. 11) is likewise the maximum circumferential wing and the wake ring to block the influence of the vortex. Considering the direction of intersection of the two sides can be installed at intervals of 3.0 to 7 times to maximize the rotational force.

In order to maximize the rotational force, it is also important to define the spacing between the circumferential wing and the circumferential wing and the wake ring and the wake ring, but it is also very important to define the spacing between the circumference wing and the wake ring.

7 is a high-power generation one-stage vortex windmill according to the present invention (invention of claim 1) (a vortex windmill having a columnar wing of one stage).

It is characterized by high power generation by increasing the generation force to maximize the excitation force.

In more detail, as shown in the front view of Fig. 7 (a), the rotary shaft end support 4 connected to the front end of the rotary shaft tip 3 having a length about one times the diameter of the tip (the rotary shaft end support is the tip 3 and the tip). The flow generated in the space between the boundary membrane border fences (5) does not affect the flow field of the rotor blades to smooth the vortex generation, and in particular, the number of supports is installed in consideration of the structural strength and influence of the entire vortex windmill. , Tip end support needs to be streamlined in the flow direction), and the circumferential edge direction flow and pressure caused by the flow generated by hitting the tip end are blocked by installing the tip boundary membrane edge fence (5) to affect the generation of vortex Don't get crazy.

Install sequentially. Therefore, the number of circumferential wings 6 can be installed by the number divided by 3 times (maximum number of installations) to 7 times (minimum number of installations) of the diameter of the circumference of the center circumference of the wake ring.

When installing the circumferential wing in one step as shown in Figure 7, the number of installation of the circumference of the circumference is proportional to the size of the circumference, but the number that can be installed is limited to one step. As the vortex windmill has more circumferential wings, more vortices are generated, and aftershock and rotational forces increase, so that the amount of power generation increases. Therefore, in order to generate a large amount of power generation like a large windmill, a method of installing a lot of circumferential wings is required.

It is the vortex wind wheel which becomes.

The largest propeller windmills currently installed are 70m long. Vortex windmills can also have the maximum size that can be achieved in multiple stages. In case of vortex windmills, like propeller windmills, when one windmill with 70m wings length is manufactured, the vortex windmills can be cut from 70m (3xd + boundary fence thickness) to 70m / (7xd + boundary border fence thickness). Can be installed. The radius value of 0.25m is also taken into account when the diameter of the center of the tip boundary membrane rim fence is 0.5m. For example, if the diameter d of the circumferential blade is 20cm and the thickness of the border fence fence is 5cm, the vortex windmill can be manufactured with a maximum of about 107 stages and a minimum of about 48 stages. This is different by designing the diameter of the circumferential blade when designing the vortex windmill.

As an example of the present invention, the first stage of FIG. 7 generates vortices at eight locations, the second stage of FIG. 8 is 21 places, the third stage of FIG. 9 is 39 places, and the fourth stage of FIG. This is where. Therefore, if the power generation of the first stage is 1, the power generation of the second stage is 2.6 times, the third stage is 4.9 times, and the fourth stage is 7.9 times. This is the case of installing the circumferential wings at intervals of 5 times including the circumferential diameter, and multiplying these values when installing at the maximum interval of 3 times.

As shown in FIG. 7, when the propeller windmill of the same diameter as in the case where the eight circumferential wings were installed in one stage was measured under the same wind conditions, the rotational torque was about 10 times stronger. Therefore, it is calculated that the vortex windmill installed in the fourth stage of FIG. 10 has a rotation torque of 79 times that of the propeller windmill. Of course, in this case as well, if the interval between the circumferential wings is narrowed to the maximum and installed three times, the multiples of these values are obtained.

As described above, the present invention relates to a large high-power power generation multi-stage vortex windmill blade, in which the number of crosses of the circumferential wings and the wake rings cross each other within a range in which the vortices do not affect each other in the flow field around the circumferential wings. The spacing between the circumference and the circumferential wing, the spacing between the wake ring and the wake ring, and the installation position of the boundary membrane edge fences, the range of influence of the occurrence of one three-dimensional vortex of the vortex windmill on the flow field should be at least 1.5 times the circumferential diameter. It is between 3.5 times maximum, so install it considering this distance. As mentioned above, the maximum number of circumferential blades that can be installed can be installed in the maximum number of circumference 3.0 times and the minimum number of circumference diameter 7.0 times considering the effects of both sides of the circumference due to the vortex generation.

In the present invention looks at the s / d ratio (invention of claim 7). In the present invention, the diameter of the circumferential blade of any one of the first circumferential wing, the second circumferential wing, the third circumferential wing, or the fourth circumferential wing is d, and the interval between the rotary wing part and the wake ring part is s. When one of the circumferential wing is a circumference and the wake ring is a plate material, s / d = 0.35 to 0.5, and when any one of the circumferential wing is a square columnar body and the wake ring is a plate, When the length is d ₁ , the s / d ₁ = 1.0 to 3.0, which is a high power generator vortex wind vane.

In more detail, when the circumferential wing (rotary wing) is the circumference and the wake ring is the plate, the s / d has the greatest aftershock force at 0.35 to 0.5, the circumferential wing is the rectangular columnar wing and the wake ring is the plate. In this case, s / d ₁ showed the greatest aftershock force between 1.0 and 3.0 (d ₁ : length of one side of the rectangular columnar body).

In the present invention looks at the appropriate spacing (invention of claim 8) between the circumferential wing and the circumferential wing. The present invention includes a plurality of circumferential wings between the circumferential wings and any one of the plurality of first circumferential wings, the plurality of second circumferential wings, the plurality of third circumferential wings, or the plurality of fourth circumferential wings. Appropriate spacing is a high output power eddy wind vane, characterized in that 3 to 7 times the diameter of the circumferential wing.

In other words, the high-power power vortex windmill rotor blade, as shown in Fig. 12 (a) is installed so as not to interfere with the peripheral flow of the rotary shaft tip support 4 around the first boundary membrane edge fence more than the inner tip 3 At the same time, since it plays a role of supporting the structural strength of the entire vortex wind vane, it is installed in consideration of this, and the desired interval is about 3 to 7 times the diameter of the circumferential wing 6 on the tip boundary membrane edge fence 5 (1 in Fig. 11). Circumferential wings (6) are installed successively, and the boundary membrane rim fence is installed at intervals of about 3 to 7 times the diameter of the wake ring (calculated in the same manner as the circumferential wings, omitted below) as shown in ② of FIG. After that, in the same manner, the circumferential wings are installed at desired intervals at about 3 to 7 times the diameter of the circumferential blades and are repeatedly installed in the direction of radiation. The number of circumferential blades and the spacing and the number of boundary membrane edges can be determined by designing the amount of power generated, and the number of circumferential wings and the wake ring can be calculated and designed.

Here, the high output power vortex wind vane rotary shaft tip 3 is preferably in a streamlined shape, such as the propeller tip of the aircraft, in order to minimize turbulence as shown in FIG.

The present invention further comprises a rotational direction propeller (11) for determining the rotational direction of the vortex windmill so as to have a constant angle to the edge fence of the outermost end of the high output power vortex windmill blade (invention of claim 13). do.

11 to In Figure 13, the rotation direction propeller 11 is installed to have a predetermined angle on the outer portion of the boundary membrane border fence (5-4) of the end serves to determine the rotation direction of the vortex windmill. If there is no rotation direction determination propeller 11, the rotation of the windmill is rotated arbitrarily in either direction so that it is fixed in one direction by the rotation direction determination propeller (11). The rotation direction determination propeller 11 can also change the rotation direction of a windmill by adjusting the angle of a propeller as shown in (11) shown in FIG.

In FIG. 13, the rotary blade rotating shaft 2 is a rotary shaft that transmits the rotational force of the vortex windmill, and the rotary shaft support 12 supports the rotary shaft while simultaneously supporting the wake ring support base 10 of FIGS. 10 to 14. It is an axis that does it. Denoted at 13 is a generator, and 14 is a bearing support case of a rotating shaft supporting a rotating shaft coupled to an internal bearing to be connected to the generator to generate and rotate the rotor inside the generator.

(9-1)-(9-4) of FIG. 14 are wake ring supporters which support a wake ring, (10) is a wake ring support base shaft, and (7-1)-(7-4) are circumferences Wake rings are fixedly installed at regular intervals from the wings. The width of the wake ring so far has been described with the same diameter as the circumferential wing, but the width of the wake ring may be larger or smaller than the diameter of the circumferential wing.

In Fig. 14, the wake rings (7-1) to (7) are spaced apart from the rotor blades, which are circumferential blades, the boundary membrane edge fences, and the rotor blades composed of the rotary shaft tip portions (3) and the rotational propellers (11). -4) and the wake ring supporters (9-1) to (9-4) for supporting the wake rings (7-1) to (7-4) and the wake ring support base (10) are fixed to the rotating shaft support. Connected to (12). The rotational force of the vortex windmill blades of the rotating chain is transmitted to the rotating shaft support bearing therebetween to rotate the rotor of the generator.

These vortex wind vane and support are connected to the vortex wind support strut 23 and the vortex wind support strut 24 by the vortex wind support axial bearing 22, and the vortex wind rudder 21 blows by this bearing. As it is smoothly oriented, the vortex wind vane is turned toward the wind and the front, and rotation occurs.

The present invention forms a plurality of holes in the inner and outer cylinders of the boundary membrane rim fence in the high-power vortex wind vane to absorb the pressure of the boundary layer when the wind flows into the inner and outer surfaces of the boundary membrane rim fence to influence the influence of the boundary layer. It is a high power generator vortex wind vane characterized by minimizing (invention of claim 11).

In Figure 15, the boundary membrane rim fence used in each stage is installed so that the two thin cylindrical to have concentric circles with each other as shown in Figure 15 (d) so that the air flows through it is manufactured by combining the circumferential wings. The tip of the boundary membrane border fence receiving the wind is streamlined as shown in the upper end of the cross-sectional view of FIG. 15 (d) so that turbulence is not caused by flow, and the lower end of the boundary membrane border fence is shown in FIG. 15 (d). As the sectional shape is cut inside, the outside is smooth and the air flowing through the inside is diffused at the end to reduce the pressure applied to the inside of the cylindrical border fence to smooth the flow. Holes at regular intervals and diameters are drilled inside and outside the cylinder of the boundary membrane rim fence to reduce the occurrence of boundary layer caused by the flow inside and outside the boundary membrane rim fence. Make it smooth.

The boundary layer forms in the flow through the boundary membrane boundary fence and there is little flow velocity on the surface. At this time, a new flow is created between the surface from the flow through the boundary membrane edge fence to the hole to relax the boundary layer, reducing the thickness of the boundary layer, and this action reduces the distance between the boundary membrane edge fences. Allow installation. The holes may be drilled up and down inside and outside the boundary membrane edge fence, or they may be drilled out of the top or bottom.

The present invention is characterized in that it is possible to stop or operate the vortex windmill which is rotating by the wake ring moving sliding device which moves the wake ring part to space the gap between the rotary blade part and the wake ring part (invention of claim 10). It is a high output power vortex wind wheel.

In FIG. 16, it is possible to adjust the space | interval between a rotary blade part and a wake ring part, when it is desired to stop the rotating vortex windmill blade, ie, a rotary blade part. In other words, when s / d is out of the range of 0.35 to 0.5, the rotor blade stops rotating immediately. The wake ring moving sliding device 15 is a sliding device for moving the wake ring back and forth, and the moving sliding motor 16 is a sliding motor for moving it. The gear sliding guide 17 is a guide geared. The wake ring controls the rotation of the rotor blade by finely adjusting the gap between the rotor blade part and the wake ring part by operating or moving the sliding motor 16 by inserting or removing electricity from the cylinder wing.

In the present invention, the arrangement of the circumferential wings of any one of the plurality of first circumferential wings, the plurality of second circumferential wings, the plurality of third circumferential wings, or the plurality of fourth circumferential wings is symmetrical with each other. Vortex wind vane of high power generation, characterized in that it is arranged either asymmetrically or asymmetrically (invention of claim 9).

Here, the rotation shaft tip insertion hole 3-1 is a space into which the rotation shaft tip 3 and the rotation shaft tip support 4 enter.

This vortex windmill is installed in front of the existing large propeller windmill as shown in Figs. 18, 19 and 20, and can be used as a starting windmill that can rotate the existing propeller windmill that does not rotate at low speed. That is, by installing the vortex windmill as shown in Figs. 18, 19, and 20 at a suitable position at the front of the propeller or at the back of the propeller, the propeller windmill can be rotated so as to rotate the propeller windmill that does not rotate at a low speed of 3 m / s or less, and the propeller at a strong wind of 25 m / s or more. When the pitch angle is leveled in the wind direction to stop the rotation, the combined vortex windmill can rotate alone to generate electricity.

 When the vortex windmill is connected to the existing propeller windmill when the hybrid windmill is manufactured to combine the vortex windmill with the propeller windmill, the front shaft of the propeller windmill connected with the generator is removed after the generator 13 of FIG. 14 is removed and the shaft support bearing case 14 is also removed. Make a connection adapter to connect to. Adapters can be manufactured in various ways. This follows the usual way.

The present invention is installed by combining the high-power power vortex windmill vane by using an adapter in the front portion or the rear portion of the existing large propeller windmill starter windmill that can rotate the large propeller windmill that does not rotate at a low speed of less than 3m / s at low speed It is a high output power vortex windmill wing which is characterized by being used (invention of claim 14).

The high output power vortex wind vane is installed in the front or rear part of the existing large propeller windmill by using an adapter, so that the propeller pitch angle of the large propeller windmill horizontally in the wind direction at 25 m / s or more can be stopped even when the rotation is stopped. It is a high output power vortex wind vane, characterized in that the combined vortex windmill can be generated by rotating alone (the invention of claim 15).

To this end, it is necessary to combine the propeller windmill rotation speed and the vortex wind speed to match the rotation speed. The number of revolutions of the vortex wind wheel depends on the number of wings. The propeller windmill's rotation speed is about 5 to 10 times faster than the two-wheeled vortex windmill. However, in FIG. 3, when the circumferential vanes of the vortex windmill become eight, the number of revolutions of the vortex windmill is about 2 times faster than that of the two sheets. Therefore, if the number of rotor blades of the vortex windmill is 5 to 10 times faster than the speed of the existing propeller windmill, it is estimated that the rotational speed will be similar if the number of circumferential wings is set to 10 to 20.

According to the present invention, any one of the circumferential wings of the first circumferential wing, the second circumferential wing, the third circumferential wing, or the fourth circumferential wing is formed as a circumferential or quadrangular columnar body, even if a strong wind is applied to the wing. It is a high output power vortex wind vane characterized by the fact that the force is dispersed throughout the columnar body and the damage is reduced (invention of claim 12).

That is, the vortex windmill of the present invention does not rotate at low wind speeds of 3 m / s or less, and problems that are pointed out in the existing propeller windmills that stop power generation due to a problem of propeller vane breakage in strong winds of 25 m / s or higher, 3 m in the vortex windmill Rotation occurs due to regular vortices even at low wind speeds of less than / s, and rotation occurs even at high winds of 25 m / s or more, but the rotor blades are formed in a columnar or square columnar body. The force of the wind is uniformly applied to the entire rectangular columnar body to solve the problem of breakage of the rotor blades, and also to solve the noise problem caused by the propeller windmill rotation due to the low rotation.

Vortex windmill rotational force in the case of Figure 7 and 10, compared to the existing propeller windmill rotational force of the same size, is increased by at least 10 times to about 80 times, it is expected to increase the amount of breakthrough power generation. And the vortex windmill is low compared to the high-speed propeller windmill of the same size, thereby reducing the risk.

Propeller windmills, which currently occupy most of the windmills, are mostly paid to foreign countries due to lack of domestic technology, while high-power multi-stage vortex windmills are 100% domestic technology, which ensures the profitability of windmills in Korea and exports to foreign countries. Being a high efficiency windmill of domestic technology. At the same time, it is expected to increase profits by expanding installation at the price of less than 1/10 of the existing propeller windmills, and show the same amount of power generation in the 10m diameter small and medium sized multistage vortex windmills compared to the existing 50m large propeller windmills due to the increase in power generation due to the dramatic increase in torque. It is expected to be. In this way, the new concept of high efficiency, which replaces the existing propeller windmills, is positioned as a new concept of high efficiency new windmills.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be obvious to those skilled in the art that various modifications and changes can be made within the scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
