[0001] APPARATUS FOR GENERATING BY WIND POWER [0002]

The present invention relates to a wind power generator capable of increasing the wind pressure of a blade and minimizing a drag force, and also capable of increasing rotational power by a rotation moment action having a strong propulsive force even when the wind speed is weak.

Generally, a wind power generator is a device that generates electric power by generating mechanical energy by wind force and then converting it into electric energy. Wind energy due to wind is infinite and clean, so it is recognized as an alternative energy.

As a new alternative energy generation device, the wind power generation device has a sufficient possibility. However, it is difficult to move the blade when the wind speed is low (for example, about 2 to 6 m / sec) There is a problem in that the efficiency of power generation is remarkably low.

To solve such a problem, Korean Patent Registration No. 10-1206701 discloses a wind turbine generator capable of generating wind at low wind speed. Such a wind turbine generator includes an air foil type wind capturer which generates an overlapping force in the same direction by constituting an overlapped region with respect to the center shaft, thereby enabling the use of drag and lift of wind simultaneously, And accelerated the output coefficient so that wind power can be generated even in a small wind.

However, since the conventional wind power generation apparatus including the above-described prior art in which power is generated even at low wind speed can increase the rotational power mainly by the arrangement of the blades, the wind speed can be instantaneously varied to 2 / sec or less There is a problem that the rotation of the blade is rapidly lowered and the power generation efficiency is lowered.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The present invention can transmit the rotational power generated by the blades 130 installed on the rotary shaft 110 of the fixed frame 100 to the generator 160 while the rotary shaft 110 is arranged horizontally or vertically, The present invention relates to a wind power generator in which power generation is performed.

A plurality of blades 130 arranged at equal intervals in a circular arc between the both-side rotary discs 120; and a plurality of blades 130 arranged at equal intervals on both sides of the rotary shaft 110 at predetermined intervals, A wind direction guiding member 140 located on the inner side of the blade 130 and disposed on the outer side of the central rotation axis 110 and a plurality of weights including a closed water pipe 200, The flywheel guide unit 170 is provided with the water circulation chamber 172 to allow the weight 200 to move the center of gravity of the rotary disc 120 in the circumferential direction of the rotary disc 120. The flywheel guide unit 170 includes a rotary disc 120 The weight 200 is moved in the circumferential direction of the rotary disk 120 so as to perform a flywheel function based on the weight of the weight 120

The blade 130 is formed with a wind collecting surface 135 having a curved surface concave from the inner end 131 to the outer end 132 of the blade 130 so that the blade 130 moves forward in the forward direction and has a rotational force, The inner end 131 of the blade 130 is installed at a position in contact with the maximum rotation circumferential portion of the airflow guiding member 140.

The distance between the inner end 131 and the outer end 132 of the blade 130 according to the present invention is much narrower than the intervals between the inner and outer ends of the wind turbine blade radially disposed in the conventional wind power generator However, the blade 130 of the present invention is disposed at the outer circumferential end portion of the wind turbine at the outermost position in the central rotary shaft 110, which can exert the maximum force, and is rotated by the rotary shaft 110 So that the power can be generated by the rotary power.

The inner end 131 of the plurality of blades 130 and the inner end 131 of the adjacent blades 130 are spaced apart from each other by a distance Thereby forming a sufficient ventilation hole portion 150 which can be advanced and discharged in the lateral direction.

The wind direction inducing member 140 of the present invention is capable of focusing and discharging the wind that flows into the vent hole portion 150 between the blade 130 and the blade 130, The strong wind pressure is transmitted to the wind trapping surface 135 of the blade 130 located in the discharge direction so that a strong rotational moment can be obtained from the plurality of blades 130 rotating in the forward direction.

The airflow guiding member 140 is formed of a circular tubular body and has an airfoil-shaped inclined surface 144 formed at a central portion thereof and extending to both sides of the central portion. And the two ends are connected to the rotary disk 120. The wind collecting unit 142 is configured such that the wind is concentrated at the center portion of the wind direction focusing unit 142 and the wind is focused on the plurality of blades 130 rotated in the forward direction Wind pressure is transmitted to generate a strong rotational power.

That is, this is introduced in the lateral direction through the ventilation openings 150 between the blades 130 and the blades 130 so that the wind hits the wind direction inducing member 140, which is a circular tubular member, The wind is concentrated along the inclined surface 144 formed in the trumpet shape of the wind deflector 142 and is discharged to the center portion.

When the wind is concentrated and discharged to the center portion of the wind direction focusing unit 142, the bundled wind is transmitted to the wind collecting surface 135 of the blade 130 located in the discharge direction, 8, wind pressure is transmitted to the wind collecting surface 135 of the blade 130 located at 12 o'clock among the plurality of blades rotating in the clockwise direction when the wind is blowing from the left side to the right side, When the wind that is collected by the wind direction inducing member 140 passes through the ventilation hole portion 150 between the blade 130 and the blade 130 and is discharged between the 12 o'clock and the 3 o'clock direction, A strong wind pressure is transmitted to the wind trapping surface 135 of the rotor 130 to obtain a rotational power with a strong rotation moment.

When the wind collected by the wind direction inducing member 140 is discharged between the 3 o'clock and 6 o'clock o'clock directions, the wind that hits the convex portion of each blade 130 placed between the 3 o'clock and the 6 o'clock direction, Since the resistance is small, the blade 130 can be smoothly rotated without significantly affecting the forward rotation.

Since the wind direction inducing member 140 according to the present invention rotates in the same clockwise direction as that of the rotation of the blade 130, the wind that is converged by the wind direction inducing member 140 is rotated in the clockwise direction, 142), which is located between the 12 o'clock and the 3 o'clock o'clock position, as more concentrated wind is blown between the 12 o'clock and the 3 o'clock direction compared to the wind blowing between the 3 o'clock and the 6 o'clock direction The strong wind pressure concentrated on the wind trapping surface 135 of the losing blade 130 is transmitted.

As described above, the blade 130 is disposed at the end portion of the rotating circumference of the wind power generator with a small width between the inner end 131 and the outer end 132, so that a strong rotational force can be generated. The inner end 131 of the blade 130 is spaced apart from the inner end 131 of the vent 130 so that the wind can pass through the blade 130 adjacent to the blade 130. [ And the strong wind pressure is transmitted to the plurality of blades 130 traveling in the forward direction to be rotated so as to obtain a rotational power having a strong rotational moment.

When the centrifugal force is generated as the rotary disc 120 rotates, the weight of the flywheel inducing unit 170 is reduced to the circumference of the rotary disc 120, So that a flywheel function having a strong driving force with high rotational inertia can be performed.

The weight water flow chamber 172 disposed on the rotary disk 120 constituting the flywheel induction unit 170 may be configured such that the weight water flow chamber 172 is different In the case of the horizontal rotary shaft 110a, the rotary disk 120 is vertically installed at both ends of the horizontal rotary shaft 110a. In the case of the vertical rotary shaft 110b, the upper and lower ends of the vertical rotary shaft 110b The rotation disc 120 is horizontally installed and the direction in which the centrifugal force of the rotation disc 120 is generated is vertically or horizontally oriented by the vertical or horizontal structure of the rotary disc 120 .

9 shows a structure in which a weight water flow chamber 172 is disposed in a rotary disk 120 vertically installed on both left and right ends of a horizontal rotation shaft 110a. It is formed by a water pipe. Therefore, as shown in FIGS. 10 and 11, the weight water accommodated in the heavy water flow chamber 172 can be eccentrically moved along the ellipse of a given trajectory without being changed in the closed water pipe. One end 172a of the elliptical long axis of the weight water flow chamber 172 is disposed close to the center of the rotary disk 120 and the other end 172b of the ellipse is disposed close to the circumferential surface of the rotary disk 120 This structure allows the weight water flow chamber 172 to be installed only within the size range of the rotary disk 120. The weight water flow chamber 172 is formed in the rotary disk 120 of the horizontal rotation shaft 110a, Respectively.

The weight water 200 is introduced into the heavy water flow chamber 172 through the injection port (not shown) at one side so that the weight water 200 can be flowed through water or oil, So that the weight water 200 introduced into the heavy water flow chamber 172 can be eccentrically moved in the weight water flow chamber 172 by 20% to 40% of the volume ratio of the weight water flow chamber 172 .

10 shows a state in which the rotation disc 120 is stopped. The number of weights internally inserted into the plurality of weight water flow chambers 172 is set to be close to the central portion of the rotation disc 120, Since the center of gravity of the rotary disk 120 is uniformly distributed in the rotary disk 120 due to the weight of the weight of the rotary disk 120 while the center of gravity of the rotary disk 120 is positioned between the center and the circumferential surface, The starting resistance due to the weight of the weight water introduced into the weight water flow chamber 172 at the time of initial rotation is minimized.

11, when a centrifugal force is generated by rotating the rotary disk 120 vertically provided at the right and left ends of the horizontal rotary shaft 110a in the vertical direction, a plurality of weights The center of gravity of the number of weights is shifted in the circumferential direction of the rotary disc 120 located at the other end 172b of the elliptical long axis and the weight of the rotary disc 120 is shifted to the circumferential surface The flywheel function, which has a high rotational inertia due to the weight of the flywheel, greatly increases the rotational power of the generator.

It is preferable that a plurality of the weight water flow chambers 172 are disposed on the rotary disk 120 and at least three water flow chambers 172 are provided, and the elliptic type closed conduit tubes constituting the heavy water flow chamber 172 are not only generally elliptical Of course, it is also possible that a rectangular shape formed at both ends of the hemispherical shape or a deformed elliptical shape in which the shortened portion of the ellipse forms a curved surface.

The rotary disk 120 provided in FIG. 12 is rotated with the vertical rotation axis 110b as an axis, and a weight water flow chamber 172 is provided in the rotary disk 120 horizontally provided at both upper and lower ends of the vertical rotation axis 110b And the weight water flow chamber 172 is formed as a circular closed communication pipe so that the weight water can move eccentrically along the circular shape, It is preferable that the weight water flow chamber 172 is disposed radially and equidistantly at a position close to the circumferential surface so that the weight water can flow into the weight water flow chamber 172 with a volume ratio of 20 to 40% Do.

13 and 14 show a state in which the rotation disc 120 is stopped. The number of weights internally inserted into the plurality of weight water flow chambers 172 is equal to the total number of the weight water flow chambers 172 The center of gravity of the weight water flow chamber 172 is uniformly distributed on the rotary disk 120 without being offset to any one side. Therefore, the rotary disk 120 is moved in the horizontal direction It is possible to minimize the influence of the weight of the weight water flowing into the weight water flow chamber 172 and to minimize the starting resistance generated during the initial rotation of the rotary disk 120.

15 and 16, when a rotary disk 120 horizontally provided at both the upper and lower ends of the vertical rotary shaft 110b is rotated in the horizontal direction to generate centrifugal force, The number of weights is eccentrically moved in the circumferential direction of the rotary disc 120 so that the center of gravity of the number of weights in the circumferential direction of the rotary disc 120 is centered. The rotational power of the generator can be greatly increased by the flywheel function that has a high rotational inertia due to the weight of the weight located in the circumferential direction of the generator.

As described above, according to the present invention, the number of weights embedded in the weight water flow chamber 172 disposed in the rotary disc 120 minimizes the starting resistance of rotating the rotary disc 120 in a stationary state, In the case where centrifugal force is generated by rotating, the flywheel function of the flywheel function by which the center of gravity of gravity is directed toward the circumferential surface of the rotating disk causes a strong propulsive force to increase the rotational power of the generator, .

While the present invention has been described with reference to the exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
