Description

High-power generating vortex windmill wing {Hihg-power generating vortex windmill wing}

The present invention is a high-power structure in the form of an integrated rotating body installed in multiple stages in the front of the multi-stage structure of the wake fixed by the excitation force of the three-dimensional three-dimensional vortex flow outflow between two structures crossing at a certain interval. It relates to power generation vortex windmill blades.

In general, wind power generation is a technology that converts kinetic energy from air into mechanical energy by rotating a windmill using aerodynamic properties, and uses this mechanical energy to generate electricity, in the form of a horizontal axis depending on the direction of the rotation axis relative to the ground. Propeller type windmills (Wind Power Generator: Patent Registration No. 10-1027055, registered on March 29, 2011) are mainly used, and are widely used from those connected to large-scale power systems to independent small power sources such as remote islands and mountainous areas. Since wind power varies greatly over time, when used as an independent power source, it is used in combination with a storage device such as charging using a storage battery or other power generation methods. Among the windmills applied to such wind power generators, propeller type windmills, which are currently known as the best windmills, have a propeller blade length of 10m to 50m in large-sized cases, and if the length of the chord at the tip of the propeller blade is increased widely, Since the air resistance increases and the rotational speed decreases, the form of increasing the rotational speed by making the tip of the blade thinner in terms of rotational efficiency is becoming the mainstream, and three or four blades are operated in the form of radial coupling at the tip of the power generation unit. However, in the case of a breeze with a small wind speed, the windmill does not rotate smoothly due to the resistance force, and does not rotate at all below about 3m/s. In addition, when there is a strong wind of about 25m/s or more, the propeller may be damaged. Therefore, the rotation is stopped by turning the angle of the propeller blade so that no rotational force is generated. In addition, a lot of noise is generated when the propeller blades with this structure are rotated, and environmental destruction problems due to large-scale base construction according to installation compared to the amount of power generation appear as a major problem.

Registered Patent Registration No. 10-1027055 (2011.3.29)

The present invention solves the problems of the existing propeller windmill, and in a vortex windmill having a ring on the wake of the circumferential wing, the wake ring and the circumferential wing are installed in multiple stages in consideration of the range of influence of the three-dimensional vortex generation. It is intended to provide a multi-stage vortex windmill blade of high power generation that increases the generation of eddy currents so that the excitation force is as large as possible.

In the present invention, the circumferential blade and the wake ring are installed to cross 90° in multiple stages (hereinafter referred to as'cross crossing') to increase the occurrence of eddy currents flowing out between the circumferential blade and the wake ring, and to increase the corresponding excitation force. It is to provide multi-stage vortex windmill blades for high power generation.

In the present invention, the rotational speed of the circumferential blade increases in linear proportion to the wind speed, whereas the propeller windmill stops the operation of the windmill at a wind speed of 25m/s or more, whereas the vortex windmill increases the rotational speed even at 30m/s or more (Fig. 3, 4), to allow the windmill to rotate at all wind speeds.

Existing large-sized propeller windmills cannot function as windmills above about 25m/s, and propeller blades are destroyed in strong winds, so a complex pitch control device that eliminates the illusion angle adjusts the windmill propeller angle and stops the rotation of the windmill. In the case of a high-power eddy current windmill, when you want to stop the rotation of the blades, you can simply stop the rotation of the blades by moving the gap between the circumferential blade and the wake ring slightly forward or backward. This can be solved by a wake ring, a wake ring support supporting the wake ring, and a wake ring moving sliding device capable of moving the support shaft.

In the high-power generation vortex windmill blade for generating high-power generation with the one-stage vortex windmill blade of the present invention, the high-power generation vortex windmill blade includes a tip portion that is the tip of the rotation shaft of the windmill, and a plurality of tip supporters formed on the edge surface of the tip portion. And, a front end boundary film rim fence formed at the ends of the plurality of tip supporters, a plurality of circumferential blades formed on the tip boundary film rim fence, and a first boundary film rim formed at the ends of the plurality of circumferential blades Including; a rotation blade portion as a fence, a wake ring disposed on the rear surface of the rotation blade portion, and a wake ring portion configured as a plurality of wake ring supporters supporting the wake ring,

The plurality of circumferential blades are formed between the front boundary film rim fence and the boundary film rim fence to increase the generation of eddy currents flowing out between the rotating blades and the wake ring part to maximize the excitation force to generate high power. It is characterized by that.

In the high-power generation vortex windmill blade for generating high-power generation with the multi-stage vortex windmill blade of the present invention, the high-power generation vortex windmill blade includes a tip portion that is a tip of the rotation shaft of the windmill, and a plurality of tip supporters formed on the edge surface of the tip portion. , A front end boundary film rim fence formed at the ends of the plurality of tip supporters, a plurality of circumferential blades formed on the front end boundary film rim fence, and a boundary film rim fence formed at the ends of the plurality of circumferential blades, A plurality of circumferential blades on the boundary film rim fence, and a rotation blade portion in which a boundary film rim fence is alternately formed on the plurality of circumferential blades so that the circumferential blades and the boundary film rim fence are formed in multiple stages; And

When the diameter of the circumferential blade in the one-stage or multi-stage vortex windmill blade is d and the distance between the rotary blade and wake ring part is s, s/d=0.35~ when the circumferential blade is circumference and the wake ring is a plate material. to 0.5, and the upper circumferential wings sagakju and is characterized in that the wake-ring when the plate member, when the length of one side of the upper body sagakju as _{d 1, s / d 1 =} 1.0~3.0.

In the one-stage or multi-stage vortex windmill blades, the proper spacing between the circumferential blades and the circumferential blades in the plurality of circumferential blades is 3 to 7 times the diameter of the circumferential blades.

In the one-stage or multi-stage vortex windmill blade, the arrangement of the circumferential blades in the rotating blade portion is to be symmetrically or asymmetrically arranged with each other.

In the one-stage or multi-stage vortex windmill blade, it is characterized in that it is possible to stop or operate the rotating vortex windmill by a wake ring moving sliding device that moves the wake ring part to the gap between the rotating blade part and the wake ring part. . In the high power generation vortex windmill blade, a plurality of holes are formed in the inner and outer cylinders of the boundary membrane fence to absorb the pressure of the boundary layer when the wind flows to the inner and outer surfaces of the boundary film rim fence to minimize the influence of the boundary layer. It is characterized by.

In the one-stage or multi-stage vortex windmill blades, even if strong wind power acts on the blades by forming the circumferential blades as a circumferential or rectangular columnar body, the force is dispersed throughout the circumferential or rectangular columnar body, thereby reducing damage.

In the one-stage or multi-stage vortex windmill blade, it further comprises a rotation direction propeller for determining the rotation direction of the vortex windmill so as to have a certain angle to the edge fence at the outermost end of the end. In the one-stage or multi-stage vortex windmill blades, the large-sized propeller windmills that do not rotate at low speeds of 3m/s or less are saved by combining and installing the high-power generation vortex windmill blades to the front or rear of the existing large-sized propeller windmills. It is characterized by being used as a starting windmill that can rotate even in the middle.

Even when the high power generation vortex windmill blades are combined and installed at the front or rear of the existing large-sized propeller windmill by using an adapter, the propeller pitch angle of the large-sized propeller windmill is set horizontally in the wind direction in a strong wind of 25m/s or more to stop rotation. It is characterized in that the combined vortex windmill can rotate and generate electricity alone.

The high-power multi-stage vortex windmill blade of the present invention has the disadvantage that the conventional large-sized propeller windmill cannot rotate at a low speed wind speed and does not rotate due to a propeller breakage problem at a high speed of about 25 m/s. High-power generation multi-stage vortex windmills rotate at all wind speeds from low to high speed while the rotation speed is low, and power generation is possible accordingly, and high-power generation multi-stage vortex windmill blades with multi-stage circumferential blades While having a high rotational force equivalent to at least 10 times the amount of generation of large propeller windmills (the difference is determined by the number of circumferential blades installed), the noise caused by high-speed rotation of the propeller windmill is significantly reduced in high-power generation multi-stage vortex windmills. There is a great effect that can also reduce damage.

(Relationship between circumferential wing and wake ring according to the present invention)

In general, a propeller windmill rotates a windmill blade having an illusion angle (inclination angle) in the wind direction, and generates electricity using this rotational force. However, when installing a circumference without an illusion angle in the wind direction as a wing (hereinafter referred to as'circumferential wing') (e.g., circumferential wing in Fig. 1), Karman Vortex is generated in the wake of the circumferential wing, and the circumferential wing is in a direction perpendicular to the flow It vibrates and does not rotate, but a structure (hereinafter referred to as a'wake ring' in the form of a ring such as a circumference, square, polygon, etc.) is cross-intersected as shown in FIG. It can be seen that the circumferential blade rotates at a specific interval when the interval is adjusted. 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 rotating blade, resulting in a rotational force.

The circumference without such an illusion angle cross-arranges the wake ring in the wake, so that the circumference becomes a wing and rotation occurs, while a three-dimensional vortex is formed near the intersection in Fig. 5, and is sucked into the three-dimensional vortex. It was found that the flow was due to the tensile force pulling the circumferential blade (wing).

1 is a diagram of a vortex windmill in the case of two rotating circumferential blades according to the present invention. Here, W: width of wake ring, D: diameter of ring center, s: distance between circumferential blade and wake ring, d: diameter of circumferential blade. Fig. 2 is a diagram of a vortex windmill in the case of four rotating circumferential blades according to the present invention. And Fig. 3 is a diagram comparing the number of rotations at the same wind speed when the circumferential blades are 2, 4, and 8 sheets. Here, the wing length: L=60mm, the gap ratio: s/d=0.35, and the ring width ratio: W/d=1.0. In Fig. 3, when the wind speed is 7m/s, the number of revolutions is 106 times for two circumferential blades, 168 times for 4 elements, and 230 times for 8 elements, and when the wind speed is 20m/s, the number of revolutions is 370 times for 2 circumferential blades. The results were 588 times in the and 806 times in the eight sheets. This means that the more the circumferential blades at the same wind speed, the more the rotational speed increases.

4 is a diagram comparing the amount of power generation between a first-stage vortex windmill (one circumferential wing and one wake ring) and a conventional propeller windmill. Here, the vortex windmill having 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 windmill, but it is less than that of the large propeller windmill under 25m/s. However, even over 25m/s, the circumferential wing rotates, so the total power generation cannot be said to be less than that of a large windmill. Because small and medium-sized windmills do not control the pitch due to economic efficiency, the wind speed stops at 13m/s and stops at 25m/s or more in large-sized propeller windmills. This is called cut off wind speed.

(Example of the present invention)

In the vortex windmill blade of the present invention, the number of rotations of the circumferential blade increases in proportion to the wind speed, and the large propeller windmill stops the operation of the windmill due to the damage of the propeller at a high speed of 25m/s or more, whereas the vortex windmill is 30m/s. Even above s, the excitation forces of the eddy current flowing out between the circumferential blade and the wake ring structure act symmetrically to each other and have a large rotational force. In the case of a propeller windmill at a strong wind speed, the thin part of the propeller blade cannot withstand wind power and is damaged, whereas when the windmill blade is circumferential, the power is distributed throughout the circumference even if strong wind power acts on the blade, reducing the risk of damage and high power generation. The vortex windmill blade has a low frequency of eddy current generated in the circumferential wake, and the experimental result is less than 1/6 of the conventional propeller windmill in the circumferential speed ratio, which is the ratio between the wind speed and the rotational speed of the blade. There is an advantage in the stability of the rotating blade according to the low-speed rotation. This shows the same result when the circumferential wing is a columnar body (a polygonal column shape including a square).

The vortex windmill blade of the present invention with the above characteristics solves the problem of noise caused by high-speed rotation, which is a problem of the conventional propeller windmill blades, while the torque is 10 times stronger than that of the existing propeller, so the power generation is very large. It is to provide a high-efficiency energy means in the era of post-nuclear power plants. When comparing the relationship in Fig. 3, which investigated the number of rotations when the number of circumferential blades is 2 and 4 and 8 circumferential blades in the case of a single wake ring, when there are 2 circumferential blades, the circumferential blade and the wake ring are There are 2 intersections, and if there are 4 circumferential wings, it becomes 8, and when there are 8 circumferential wings, it becomes 16. Therefore, the number of revolutions is 1.6 times more for 4 blades than for 2 circumferential blades, and 2.2 times more for 8 circumferential blades.

The more the number of circumferential blades, the more the rotational force increases, the greater the excitation force, the greater the torque and the greater the power generation. Therefore, it can be seen that the amount of power generation is increased by installing more circumferential blades as needed. However, when one wake ring is installed and the circumferential blades are arranged accordingly, the number of circumferential blades is limited due to the proper spacing between the circumferential blades due to the mutual influence of the three-dimensional vortex occurring at the intersection.

In the present invention, in order to overcome this limitation and find a way to install more circumferential blades, first, a three-dimensional eddy current is generated and the range that influences each other is investigated, and the circumferential blades are spaced out of the range of adverse effects. Was installed. The eddy currents affected by other currents are not regular and cause a distorted eddy current, thereby weakening the excitation force, so this badly affected range must be considered. In order to find out the range of influence on the flow of the three-dimensional eddy current occurring near the crossing of the circumferential wing crossing, the flow was first visualized to investigate the size of the flow field, and the flow velocity of the entire wake flow field was measured with a velocimetry.

First, a smoke wire visualization method was used to generate smoke upstream of the circumferential wing so that the flow can be seen with the naked eye. FIG. 5(a) is a visualized photograph of a three-dimensional vortex flow occurring near the intersection of the circumferential wing crossing the cross and a sketch thereof. And in order to measure the range of influence of the eddy current acting on the surface of the circumferential blade, that is, the range of influence of the three-dimensional vortex flow occurring near the intersection in the direction of the circumferential blade axis (y-axis), oil is applied to the circumferential blade. This is a visualized photo of the oil film attached to the flow field and unfolded after a certain period of time. Fig. 5(b) is a visualization photograph of the flow of vortex generation on the surface of the circumferential blade by the oil film method. Here, α: the spread angle of the oil film, s: the distance between the circumferential blade and the wake ring, d: the diameter of the circumferential blade.

Visualization of Fig. 5(b), which investigates how far the vortex generated periodically as shown in Fig. 5(a) is affected in the y-axis direction, which is the direction of the circumferential wing, by the wake ring cross-installed on the wake of the circumferential wing. In the picture, when two structures are attached to each other, the surface flow of the circumferential wing at i)s/d=0 ranges from y/d=0 corresponding to ① to about y/d=1.7 corresponding to ②. It can be seen that it has an effect, and it can be said that there is little effect between ②y/d=1.7 and ③y/d=3.5, but above ③y/d=3.5, it has a constant width without any effect, and y/d=0 It shows a symmetrical appearance on both sides, centering on.

This indicates that the eddy current occurs periodically in a bilaterally symmetrical shape around y/d=0. The structure of the upstream circumferential wing is slightly spaced apart, showing a different shape from i)s/d=0 at ii)s/d=0.35. Looking at the surface flow of the circumferential wing, it can be seen that it affects the range from y/d=0 corresponding to ④ to about y/d=1.5 corresponding to ⑤, and y/d= corresponding to between ⑤ and ⑥. It shows that there is little effect between 1.5 and 3.5. After y/d=3.5, there is no effect at all, and the width is constant.

iii) When the circumferential wing is alone without a wake ring in the wake of the circumferential wing with s/d=∞, the entire flow of the circumferential wing has the same width as ⑦. It has the same width as the flow at the position completely out of the influence of the eddy current generated by the wake ring, such as ③ and ⑥. From the above results, when the wake ring is cross-intersected in the wake of the circumferential blade, the range of influence of the eddy current occurring near the cross-intersection is partially affected from y/d=1.5 to the maximum y/d=3.5 at s/d=0.35. It can be judged as having an effect. In the case of s/d=0.35∼0.5, s/d=0.5 between the circumferential blade and wake ring shown in the present invention, a similar trend is shown.

As described above, in the state where the circumferential blade and the wake ring were cross-intersected and fixed, the flow velocity of the entire circumferential blade wake flow field was investigated with a hot wire velocimetry for the range of influence of the vortex flow of the circumferential blade wake. 6 shows the average velocity distribution of the flow space field in the z-axis direction vertically perpendicular to the wake flow direction and the horizontal horizontal direction (y-axis direction as the circumferential wing axis direction) to the flow direction. In other words, it shows the range in which the three-dimensional eddy current generated near the intersection in the state where the circumferential wing and the wake ring cross each other affects the flow in the z-axis and y-axis directions.

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

First, when y/d=1.0, looking at the flow of the circumferential wing and wake ring wake, the average flow velocity value ㎀/U between z/d=4.0 and z/d=-4.0 shows values between 1.0 and 1.5, and z It appears that the inside of ② and ③ where /d is within ±1.5 is relatively affected. After that, in the ranges ① and ④ where the value of z/d is up to ±3.5, it can be seen that the influence gradually weakens while showing a slight slope. This can be seen in comparison with y/d=4.0 and y/d=6.0, which are outside the range of influence of the eddy current. This shows a similar trend at y/d=1.5 and y/d=2.0. At y/d=3.0, the effect of eddy currents is less, and when compared within the ranges of ⑤,⑥,⑦,⑧ of y/d=4.0 and y/d=6.0, a similar trend is shown, but z/d=1.0 at z/ Comparing the average flow rate values between d=1.5 reveals a slight difference. In the drawing of the results of this experiment, y/d=3.5 was omitted, but the trend was similar to y/d=3.0.

In the results of Figs. 5 and 6, which closely investigated the range in which the three-dimensional eddy current affects the entire flow field, the vortex generated between the two structures is the circumferential blade diameter 1.5 in the direction of the circumferential blade axis y in the left and right direction of the flow. It can be concluded that it affects between 1.5 times and 3.5 times, and between 1.5 times and 3.5 times the diameter of the circumferential blade in the z-axis direction in the vertical direction of the flow. From the above conclusion, the proper spacing to install the circumferential blades and circumferential blades at each stage of the vortex windmill blade in parallel is 1.5 times the minimum range for vortex effect (1.0 times to add 0.5 times the diameter radius of the circumferential blade) and vortex effect. The maximum range is 3.5 times (3.0 times plus 0.5 times the diameter radius of the circumferential blade).

That is, it can be seen that the eddy current has a large effect within 1.5 times the diameter of the circumference, and gradually decreases over the range, and has no effect over 3.5 times. Therefore, it should be installed at intervals to deviate from this section to obtain the greatest possible excitation force due to eddy currents. However, in the case of installing a border fence that can absorb or block the effect of vortex even between these sections, it is possible to install more circumferential blades by narrowing it to around 1.5 times the maximum circumferential blade diameter. Also in the wake ring, the wake ring is a structure of wake crossing the circumferential wing, so in Figs. 5 and 6, it can be seen that the distance between the wake ring and the wake ring affects between 1.5 and 3.5 times the width of the wake ring. . Therefore, considering this range, the wake rings are concentric It must be installed.

In more detail, as a result of measuring the range y/d (y: axial distance of the circumferential blade, d: diameter of the circumferential blade) that the three-dimensional vortex generated between the circumferential blade and the wake ring structure extends in the axial direction of the circumferential blade, Fig. 5 As shown in Fig. 1, it can be seen that the effect is large at 1.5 times or less of the structure diameter, and the effect is insignificant at more than 1.5 times the diameter of the structure.

At the same time, the circumferential wing and wake ring are not the surface of the circumferential wing Looking at the effect of the flow in the space field, the distance between the circumferential blade and the wake ring s/d=0.35 (s = the gap between the circumferential blade and the wake ring, d: diameter of the circumferential blade) and fixed with a hot wire probe. 6, the flow velocity distribution of the flow field around the two structures is measured while moving In the vertical z-axis direction (although there are slight differences each), the effect is large at 1.5 times or less of the diameter of the circumferential blade, but the effect is small between 1.5 and 3.5 times. Therefore, the circumferential blades are arranged in consideration of minimizing the mutual interference of eddy currents. Therefore, the distance between the circumferential wing and the wake ring should be arranged so that the distance between the minimum circumferential wing or the wake ring is 1.5 times the diameter of the wake ring and the maximum 3.5 times.

When the wake ring is installed in multiple stages, there is an effect of eddy current between the first and second wake rings, so it is possible to block the effect of the vortex by installing boundary fences to block this.

In the above, the distance between the circumferential blade and the circumferential blade (1 in Fig. 11) is up to 7.0 times the diameter of the circumferential blade when considering both directions of the two circumferential blades (3.0 times the maximum range affected by vortex effect × 2 (both sides) = 6.0 times). 7 times the diameter of the circumferential blade (0.5 × 2) plus 7 times, not described below) At least 3.0 times (minimum range of vortex effect 1.0 × 2 (both sides) = 2.0 times the diameter of the circumferential blade (0.5 × 2) In addition, the maximum circumferential wing and wake ring should be installed with an interval of 3.0 times (not described below) or more, and the gap between the border fence and the border fence (2 in Fig. 11) is similarly applied to block the effect of vortex. It can maximize the rotational force by installing it with an interval of 3.0 to 7 times in consideration of both directions of the intersection.

It is important to determine the distance between the circumferential blade and the circumferential blade, and the wake ring and the wake ring in order to maximize the rotational force, but it is also very important to determine the gap between the circumferential blade and the wake ring.

In more detail, as shown in the front view of Fig. 7(a), the rotation shaft distal end support 4 connected with a length of about 1 times the distal diameter of the rotation shaft distal end 3 (the rotation shaft distal end support includes the distal end 3 and the distal end The flow generated in the space between the boundary fences (5) does not affect the flow field of the rotating blade so that eddy currents are smoothly generated.In particular, the number of supports has an effect on the structural strength of the entire vortex windmill, so it is installed in consideration of this. , The front end support needs to be streamlined in the flow direction) by installing a border fence (5) at the end of the end to block the flow and pressure in the direction of the circumferential blade caused by the flow hitting the tip, thereby affecting the occurrence of vortex. Try not to go crazy.

In addition, the first boundary film rim fence (5) is provided with an interval of 3 to 7 times the diameter of the circumferential blade including the diameter of the circumferential blade and the width of the wake ring. 1) is installed, and the circumferential blade (6) is another circumferential blade (6) with a distance between 3 and 7 times the diameter of the circumferential blade on both sides at the intersection of the circumferential blade (6) and the wake ring (7). Are installed sequentially. Therefore, the number of circumferential blades 6 can be installed as much as the number divided by 7 times (minimum number of installation) from 3 times the diameter of the circumferential blade (maximum installation number) to the central circumference length of the wake ring.

In Figs. 10-14, the space between the circumferential blades is 5 times including the diameter of the circumferential blades. However, it can be installed at three times the interval or seven times the interval. The circumferential wings installed in the first stage will be referred to as circumferential wings as they are.

The front part of the border fence 5 at the front end is made in a streamlined shape, and the thickness of the fence is made as thin as possible so that there is little difficulty in flow. However, since it plays the role of supporting the tip support and affects the structural strength of the entire vortex windmill, it is manufactured in response to the capacity when designing the vortex windmill.

It is a one-stage vortex windmill.

When the circumferential blades are installed in one stage as shown in FIG. 7, the number of circumferential blades is proportional to the size of the circumferential diameter, but the number that can be installed is limited to one stage. Vortex windmills generate more eddy currents as the number of circumferential blades increases, and as the excitation and rotational power increase, the amount of power generation increases. Therefore, a method of installing more circumferential blades is required to generate a large amount of generation like a large windmill.

The multi-stage vortex windmill blade (invention of claim 2) according to the present invention further comprises a circumferential wing and a wake ring alternately on the one-stage vortex windmill wing consisting of one circumferential wing, and the circumferential wing and wake ring are composed of multiple stages. It is a vortex windmill wing.

In the high-power generation vortex windmill blade for generating high-power generation with the multi-stage vortex windmill blade according to the present invention, the high-power generation vortex windmill blade includes a tip portion 3 that is a tip of the rotation shaft of the windmill, and a plurality of edges formed on the edge surface of the tip portion. The plurality of tip supports (4), the front boundary film rim fence (5) formed at the ends of the plurality of tip support, the plurality of circumferential blades (6) formed on the boundary film rim fence of the tip, and the plurality of A boundary film rim fence (5-1) formed at the end of the circumferential blade, a plurality of circumferential blades on the boundary film rim fence, and a boundary film rim fence are alternately formed on the plurality of circumferential blades.

The largest propeller windmill currently being installed has a windmill blade length of 70m. Vortex windmills can also have a maximum size that can be done in multiple stages. Vortex windmills, like propeller windmills, have a single wing length of 70m, and the number of stages of the vortex windmill is at least 70m/(7×d+the thickness of the border fence) at a maximum of 70m (3×d + thickness of the border fence). Can be installed. Here, when the diameter of the central part of the border fence of the edge of the front end is 0.5m, the radius value of 0.25m is also considered. For example, if the diameter d of the circumferential wing is 20 cm and the thickness of the border frame fence is 5 cm, the maximum can be about 107 stages, and the minimum about 48 stages of the vortex windmill can be manufactured. This differs by determining the diameter of the circumferential wing when designing a vortex windmill.

As an example of the present invention, in the case of the first stage of FIG. 7, eddy currents occur at 8 locations, in the case of the second stage of FIG. 8, 21 locations, in the case of the third stage of FIG. 9, and 63 locations, in the case of the fourth stage of FIG. This is the place. Therefore, considering the power generation amount of the first stage as 1, the power generation amount 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 a case where the circumferential blades are installed at an interval of 5 times including the circumferential diameter, and when installed at an interval of 3 times the maximum narrowing, these values are several times.

As a result of comparing and measuring a propeller windmill having the same diameter under the same wind speed condition as in the case where 8 circumferential blades were installed in one stage as shown in FIG. 7, the rotation torque was about 10 times stronger. Therefore, it is calculated that the vortex windmill installed in 4 stages of FIG. 10 has a rotation torque of 79 times that of the propeller windmill. Of course, even in this case, if the circumferential wing spacing is narrowed to the maximum and installed at three times the distance, these values are several times.

As described above, the present invention relates to a large-sized high-power power generation multi-stage vortex windmill blade in which the number of cross-crossing of the circumferential blades and the wake rings is installed within a range in which the eddy current does not affect the flow field around the circumferential blade. The spacing between the circumferential blades, the gap between the wake ring and the wake ring, and the installation positions of the boundary fences are the range of influence on the flow field by the occurrence of one three-dimensional vortex of the vortex windmill. Since it is between 3.5 times maximum, install it considering this distance. As mentioned above, the maximum number of circumferential blades that can be installed can be installed from 3.0 times the circumference diameter to the maximum number at 7.0 times the circumferential diameter in consideration of the effect of both sides of the circumferential blade due to vortex generation.

In the present invention, the s/d ratio (the invention of claim 3) will be described. In the present invention, when the diameter of the circumferential blade is d and the distance between the rotary blade and the wake ring part is s, when the circumferential blade is a circumference and the wake ring is a plate material, s/d = 0.35 to 0.5, and When is a square columnar body and the wake ring is a plate, when the length of one side of the square columnar body is d ₁ , s/d ₁ = 1.0 to 3.0 is a high power generation vortex windmill blade.

In more detail, when the circumferential wing (rotary wing) is a circumference and the wake ring is used as a plate material, the excitation force is the largest at 0.35 to 0.5 in s/d, and the circumferential wing is used as a square pillar columnar wing and the wake ring is used as a plate material. In the case of s/d _1, the excitation force was greatest between 1.0 and 3.0 (d ₁ : the length of one side of the rectangular columnar body).

In the present invention, it looks at the proper spacing between the circumferential blade and the circumferential blade (invention of claim 4). The present invention is a high power generation vortex windmill blade, characterized in that the proper spacing between the circumferential blade and the circumferential blade in the plurality of circumferential blades is 3 to 7 times the diameter of the circumferential blade.

In other words, the high-power generation vortex windmill rotation blade unit is installed so as not to interfere with the surrounding flow of the first boundary membrane rim fence or more with the rotation shaft tip end support 4 around the inner tip part 3 as shown in Fig. 12(a). , At the same time, it plays a role of supporting the structural strength of the entire vortex windmill blade, so it is installed in consideration of this, and the desired distance is about 3 to 7 times the diameter of the circumferential blade (6) on the boundary membrane rim fence (5) at the tip (1) of FIG. ) And install the circumferential blade (6) continuously, and install the boundary membrane rim fence at intervals of about 3 to 7 times the diameter of the wake ring (calculated in the same way as the circumferential blade, omitted below) as shown in ② in FIG. After doing the same, install the circumferential blades at a desired interval from 3 to 7 times the diameter of the circumferential blades, and install them continuously in the radiation direction. The number of circumferential blades and the distance and number of the boundary membrane rims can be installed by calculating and designing the number of circumferential blades and wake rings corresponding to the amount of power generation after determining the design power generation amount.

Here, the high-power generation vortex windmill blade rotation shaft end portion 3 is preferably a streamlined shape such as the propeller tip of the aircraft in order to minimize the occurrence of turbulence as shown in Fig. 12 (b).

The present invention further comprises a rotation direction propeller 11 that determines the rotation direction of the vortex windmill so as to have a certain angle to the edge fence at the outermost edge of the high-power generation vortex windmill blade (the invention of claim 9). do.

11 to In FIG. 13, the rotational direction propeller 11 serves to determine the rotational direction of the vortex windmill by installing it at an angle outside the boundary membrane rim fence 5-4 at the end. In the absence of the propeller 11 for determining the direction of rotation, since the windmill rotates arbitrarily in either direction, it is fixed in one direction by the propeller 11 for determining the direction of rotation. Rotation direction determination The propeller 11 can also change the rotation direction of the windmill by adjusting the angle of the propeller as shown in (11) shown in FIG.

In Fig. 13, the rotating shaft 2 of the rotating blade part is a rotating shaft that transmits the rotational force of the vortex windmill, and the rotating shaft support 12 supports the rotating shaft, while also supporting the wake ring support support shaft 10 of Figs. It is the axis that does. (13) is a generator, and (14) is a rotating shaft support bearing case, which is connected to the generator by supporting the rotating shaft coupled to the inner bearing to rotate the rotor inside the generator to generate power.

14 (9-1) to (9-4) are wake ring supports that support the wake ring, (10) is the wake ring support support shaft, and (7-1) to (7-4) are circumferential These wake rings are fixedly installed at regular intervals from the wings. Until now, the width of the wake ring has been described as the diameter of the circumferential blade, but the width of the wake ring may be larger or smaller than the diameter of the circumferential blade.

In FIG. 14, the wake rings 7-1 to (7) are spaced apart from the rotating blades, which are a rotating body composed of circumferential blades, boundary membrane rim fences, and rotating shaft tip 3 and rotating propellers 11. -4) and the wake ring supports (9-1) to (9-4) that support the wake rings (7-1) to (7-4), and the wake ring support support shaft (10) is fixed to support the rotating shaft. Connected to (12). The rotational force of the blade of the vortex windmill, which is a rotating body, is transmitted to the bearings of the rotating shaft support between them to rotate the rotor of the generator.

These vortex windmill blades and supports are connected to the vortex windmill support post 23 and the vortex windmill post support 24 by a vortex windmill support shaft bearing 22, and the direction in which the vortex windmill rudder 21 blows by this bearing It is smoothly directed, and the vortex windmill blades are directed to the wind and rotates to generate power.

The present invention forms a plurality of holes in the inner and outer cylinders of the boundary film rim fence in the high-power eddy current windmill blade to absorb the pressure of the boundary layer when the wind flows to the inner and outer surfaces of the boundary film rim fence, thereby exerting the influence of the boundary layer. It is a high-power generation vortex windmill blade characterized by minimization (invention of claim 7).

In FIG. 15, the boundary membrane rim fence used in each stage is manufactured by combining the circumferential wings by installing two thin cylinders to have concentric circles as shown in FIG. 15(d) so that air passes through the inside. The shape of the front end of the boundary membrane rim fence facing the wind is streamlined as in the upper end of the cross-sectional view of Fig. 15(d) so that turbulence is not possible due to the flow, and the end of the lower end of the boundary film rim fence is shown in Fig. 15(d). As shown in the cross-sectional view, the inside is cut and the outside is smooth and the air passing through the inside flows so that it diffuses from the end, reducing the pressure applied to the inside of the cylindrical border fence to smooth the flow. A hole with a certain distance and diameter is drilled inside and outside the cylinder of the boundary film rim fence to reduce the occurrence of boundary layer caused by flow inside and outside the boundary film rim fence, thereby preventing the occurrence of vortex between the circumferential wing and wake ring Make it smooth.

Boundary film A boundary layer is generated in the flow flowing through the surface of the boundary fence and there is little flow velocity on the surface. At this time, a new flow is created between the surfaces from the flow flowing inside the boundary film rim fence to relieve the boundary layer to reduce the thickness of the boundary layer. This action reduces the distance between the boundary film rim fences, thereby reducing more circumferential wings. Make it installable. Holes can be drilled up and down inside and outside the border fence, or can be drilled at the top or bottom so as to be offset from each other.

The present invention is characterized in that it is possible to stop or operate a rotating vortex windmill by a wake ring moving sliding device that moves the wake ring part to a gap between the rotating blade part and the wake ring part (the invention of claim 6). It is a high-power generation vortex windmill blade.

In Fig. 16, when it is desired to stop the rotating vortex windmill blade, that is, the rotating blade part, it is possible to adjust the distance between the rotating blade part and the wake ring part. In other words, when s/d is out of the range of 0.35 to 0.5, the rotating blade stops rotating immediately. The wake ring moving and sliding device 15 is a sliding device that moves the wake ring back and forth, and the moving sliding motor 16 is a sliding motor that makes it move. The geared sliding guide 17 is a guide made of a gear type. In the wake ring, the moving sliding motor 16 is operated by inputting or subtracting electricity from the space between the circumferential blade and controlling the rotation of the rotary blade by finely adjusting the gap between the rotary blade and the wake ring part.

The present invention is a high-power generation vortex windmill blade, characterized in that the circumferential blades are arranged symmetrically or asymmetrically to each other (the invention of claim 5).

Until now, the circumferential blades have been arranged with an emphasis on the spacing of the circumferential blades, and have been partially symmetrical or asymmetric, but may include a high-power generation vortex windmill blade, characterized in that the entire circumferential blades are arranged in a complete symmetry as shown in FIG. . Here, the rotation shaft tip insertion hole 3-1 is a space for the rotation shaft tip 3 and the rotation shaft tip support 4.

This vortex windmill is installed in front of the existing large propeller windmill as shown in FIGS. 18, 19, and 20, so that the existing propeller windmill that does not rotate at low speed can be used as a starting windmill capable of rotating at low speed. That is, a vortex windmill is installed in an appropriate place in the front of the propeller or behind the propeller as shown in Figs. 18, 19, 20, and the propeller that does not rotate at a low speed of 3m/s or less is started to rotate, and the propeller in strong winds of 25m/s or more. Even when rotation is stopped by setting the pitch angle horizontally to the wind direction, the combined vortex windmill can be rotated alone to generate power.

When manufacturing a hybrid windmill that combines a vortex windmill with a propeller windmill, when connecting a vortex windmill to an existing propeller windmill, remove the generator 13 in Fig. 14 and then remove the rotation shaft support bearing case 14 at the front of the propeller windmill rotation shaft to which the generator is connected. Make a connection adapter and combine it. Adapters can be manufactured in various ways. This follows the usual method.

The present invention is a starting windmill capable of rotating the large propeller windmill that does not rotate at a low speed of 3m/s or less by combining and installing the high-power generation vortex windmill blades at the front or the rear of the existing large propeller windmill. It is a high-power generation vortex windmill blade characterized by being used as (invention of claim 10).

Even when the high power generation vortex windmill blades are combined and installed at the front or rear of the existing large-sized propeller windmill by using an adapter, the propeller pitch angle of the large-sized propeller windmill is set horizontally in the wind direction in a strong wind of 25m/s or more to stop rotation. It is a high-power generation vortex windmill blade characterized in that the combined vortex windmill can rotate and generate electricity alone (the invention of claim 11).

For this, it is necessary to combine the propeller windmill rotational speed with the vortex windmill rotational speed. The number of revolutions of a vortex windmill varies according to the number of blades. The rotational speed of a propeller windmill is about 5 to 10 times faster than that of a vortex windmill with two circumferential wings. However, as shown in FIG. 3, when the number of circumferential blades of a vortex windmill becomes eight, the number of rotations is increased in linear proportion to about twice as much as two. Therefore, compared to the case where the number of blades of a vortex windmill is two, the rotational speed of the conventional propeller windmill is 5 to 10 times faster. If the number of circumferential blades is adjusted to 10 to 20, the rotational speed is estimated to be similar.

The present invention is a high-power generation vortex, characterized in that the damage is reduced by distributing the force to the entire circumference or square column even though the circumferential wing is formed into a circumferential or rectangular columnar body, even if strong wind power acts on the wing (the invention of claim 8). It is a windmill wing.

That is, the eddy current windmill of the present invention does not rotate at a low wind speed of 3 m/s or less, and in a strong wind of 25 m/s or more, the problems pointed out in the conventional propeller windmill that stop power generation due to the problem of propeller blade breakage, are 3 m in the vortex windmill. Rotation occurs due to eddy currents that occur regularly even at low wind speeds of less than /s, and rotation occurs even in strong winds of 25m/s or more, but the rotating blades are formed in a circumferential or square columnar body, so even if strong wind power acts on the blades, It is possible to solve the problem of damage to the rotating blades by evenly acting on the entire square columnar body, and also to solve the noise problem that occurs when the propeller windmill rotates due to low rotation.

The rotational force of the vortex windmill in the cases of FIGS. 7 and 10 is increased from a minimum of 10 times to a maximum of about 80 times compared to the rotational force of a conventional propeller windmill of the same size, and a remarkable increase in power generation is expected. In addition, the vortex windmill rotates lower than the high-rotation propeller windmill of the same size, thereby reducing the risk accordingly.

Currently, propeller windmills, which occupy most of the current windmills, are mostly profits paid to foreign countries due to lack of domestic technology, whereas high-power multi-stage multi-stage vortex windmills are 100% domestic technology, securing all the profitability of windmills in Korea and exporting them to foreign countries. It is a high-efficiency windmill of domestic technology. At the same time, it is expected to increase profits by expansion and installation at a price less than 1/10 of the existing propeller windmills, and due to the increase in power generation due to the remarkable increase in the rotational power, the same power generation is achieved in small and medium-sized multi-stage vortex windmills with a diameter of 10m compared to the existing 50m class large propeller windmill. Is expected. As such, it is possible to obtain the effect of supplementing the disadvantages of the propeller windmill by securing the technology to establish a new concept of high-efficiency new flagship windmill that completely replaces the existing propeller windmill and install it in a hybrid form with the existing propeller windmill.

Although the present invention has been described in detail only with respect to the described specific embodiments, it is natural for those skilled in the art that various modifications and modifications can be made within the scope of the technical idea of the present invention, and such modifications and modifications fall within the scope of the appended claims. Will do. In particular, the rotary wing can be used as a columnar wing of various shapes in addition to a columnar wing or a square columnar wing.
