Wind power generator with wind induction device {A wind power generator with wind inducing device}

The present invention relates to a wind generator, and more particularly to a wind generator capable of concentrating a small amount of wind through the wind induction device.

A wind generator is a device that produces electricity by using wind as an energy source. Hydroelectric power is the power of water, and thermal power is the power of steam to turn generators to generate electricity, while wind generators are power generators that turn power generators into wind power.

Wind power generators do not consume fuel because they use wind, and are green and green energy without environmental pollution, and have a low noise.

Wind generators are divided into horizontal and vertical axes. In the horizontal axis method, the wing is made horizontal with the ground, and in the vertical axis method, the wing is formed perpendicular to the ground. The vertical axis system can generate power even if the wind blows from any direction, and has a merit that it occupies a small area.

However, in the case of the vertical axis small generator, there is a problem in that the power generation efficiency is low because less wind does not generate enough power.

The present invention is to solve the problems described above, and is related to enabling efficient power generation by allowing sufficient wind to be concentrated even if a small wind is blown by using a wind guidance device including an external rotor and a wind guide.

According to a preferred embodiment of the present invention, the upper surface and the lower surface is opened, one side surface side plate is formed, the other side is a wind conductor formed extending from one end of the outer rotor and the outer rotor formed with a plurality of spokes Wind guidance device comprising a; And a windmill formed inside the outer rotor, and rotated by the wind flowing through the wind conductor. The opening area of the wind conductor is the outer rotor so as to easily concentrate the wind through the outer rotor side. It increases toward the outside, the side blocking plate is provided with a wind generator, characterized in that extending from the one side in which the wind conductor and the outer rotor in contact with each other clockwise.

According to an embodiment of the present invention as described above, first, it is possible to induce sufficient wind through the wind conductor.

Second, the side blocking plate is formed on one side and the introduced wind rotates the windmill in the form of vortex, and escapes to the other side.

Third, since the rotation speed can be amplified in two stages by applying the first acceleration gear and the second acceleration gear, large-capacity power generation is possible.

Fourth, since the induction roller is always rotated in the wind blowing direction, the windmill can be rotated in any direction.

Fifth, since the generator tower in which a plurality of wind generators are vertically superimposed are connected to each other by a horizontal fixed shaft, stable and high efficiency power generation is possible.

And a perspective view of another system, FIG. 6 is a perspective view illustrating a generator tower of a wind generator according to another embodiment of the present invention.

In the wind generator according to the preferred embodiment of the present invention, the upper and lower surfaces are opened, the side blocking plate 11 is formed on one side, the outer rotary body 10 is formed with a plurality of spokes 12 on the other side And a wind induction device 20 extending from one end of the external rotating body 10; And a windmill formed inside the outer rotor 10 and rotated by the wind flowing through the wind inductor 20. The wind concentration through the outer rotor 10 is provided. To facilitate the opening, the opening area of the wind conductor 20 increases toward the outside of the outer rotor 10, and the side blocking plate 11 is in contact with the wind conductor 20 and the outer rotor 10. It extends clockwise from one side.

The wind power generator of the present invention includes a wind induction device and a windmill, and the wind induction device includes an outer rotor 10 and a wind inductor 20.

As shown in FIG. 1, the outer rotor 10 is positioned outside the windmill 30 to perform a function of allowing wind to flow into the windmill 30. The upper and lower surfaces of the outer rotor 10 are opened so that sufficient wind is introduced.

Side blocking plate 11 is formed on one side of the outer rotor 10, a plurality of spokes 12 are formed on the other side. The spokes 12 are formed in the form of vertically connecting the upper and lower bands formed at the edges of the upper and lower surfaces, and maintains the shape of the outer rotor 10 even if a lot of wind blows, and receives less wind resistance. Play the role of

Side blocking plate 11 is made of a closed form as a whole, the wind induced by the wind inductor 20 is blocked by the side blocking plate 11 to return the windmill 30 in the vortex form. If there is no side blocking plate 11, there is a problem that the wind through the position of the side blocking plate 11 or other wind is introduced to prevent the smooth rotation of the windmill 30.

The windmill 30 is located in the outer rotor 10. Wind introduced through the external rotor 10 rotates the windmill 30 inside the external rotor 10. The wind that rotates the windmill 30 again exits to the outside, the windmill 30 continues to rotate as this process is repeated.

As shown in Figure 1, the wind conductor 20 is formed integrally extending from one end to the outer rotary body 10, consisting of an upper surface extension plate, lower surface extension plate, right side extension plate, left side extension plate. In order to focus the wind to guide the external rotor 10, the opening cross-sectional area of the wind conductor 20 is made to increase gradually toward the outside of the external rotor 10. As a result, a sufficient amount of wind can be introduced at a portion where the wind is first introduced, and as the wind velocity increases as the wind is gradually approached to the outer rotor 10, the outer rotor 10 may be blown even with a small amount of wind. The effect of strong winds is introduced.

That is, as a result, the effect of the concentrated flow of wind is primarily generated by the wind conductor 20, and the rotation of the windmill 30 sufficiently due to the effect that the vortex is generated by the external rotor 10. You can expect.

As shown in FIG. 1, the left side extension plate extends in a tangential direction from one side where the wind conductor 20 and the external rotating body 10 are in contact with each other, and the right side extension plate is more than the extending direction of the left side extension plate. It extends in the direction rotated counterclockwise.

The side blocking plate 11 extends in a clockwise direction from one side in contact with the left side extending plate, and the cross-sectional area of the side blocking plate 11 is formed to be smaller than half of the entire side surface. In the case of forming a larger area than half, the wind inflow area is reduced, so that the rotation of the entire windmill 30 is not easy. When the area of the side blocking plate 11 is formed to be narrower than 1/4 of the entire circumferential area of the outer rotor 10, the side windshield 30 is formed by rotating the windmill 30. Since the phenomenon of a backflow collides with the wind flowing into the portion that is not, it is preferable to form a larger area than 1/4.

The rotating shaft 122 is rotated.

As shown in FIG. 5, a first bearing 120, a second bearing 121, and a rotation shaft 122 are provided to rotate the windmill 30.

The first bearing 120 and the second bearing 121 may be formed in the same shape, and are formed at the center of the upper surface of the upper frame 60 and the bottom frame 40, respectively.

The rotating shaft 122 is fitted to the first bearing 120 and the second bearing 121.

The rotating shaft 122 penetrates the center of the windmill 30, and the windmill 30 is fixed to the rotating shaft 122, so that when the windmill 30 is rotated by wind, the rotating shaft 122 is simultaneously rotated.

In the wind generator according to a preferred embodiment of the present invention, provided between the bottom frame 40 and the intermediate frame 50, the main gear 130 to rotate at the same time with the rotary shaft 122; A first acceleration gear 131 meshed with the main gear 130 and rotated; A second acceleration gear 132 meshed with the first acceleration gear 131 and rotated; And a support gear 133 which rotates by being engaged with the second acceleration gear 132, and as the second acceleration gear 132 rotates, the alternator 160 outputs an alternating current. Is done.

As shown in FIG. 5, a main gear 130, a first acceleration gear 131, a second acceleration gear 132, and a support gear 133 are included.

The main gear 130 rotates at the same time as the rotation shaft 122 and has the same rotational speed as that of the windmill 30.

The first acceleration gear 131 rotates in engagement with the main gear 130. Since the number of teeth of the first acceleration gear 131 is smaller than that of the main gear 130, the rotation speed is primarily amplified.

The second acceleration gear 132 is rotated in engagement with the first accelerator. Since the number of teeth of the second acceleration gear 132 becomes smaller than the first acceleration, the rotation speed is amplified secondarily.

The support gear 133 rotates in engagement with the second acceleration gear 132 and prevents left and right flow of the second acceleration gears 132 and 142.

As the second acceleration gear 132 rotates, the generator provided in the generator case rotates to output an alternating current. That is, the second acceleration gear 132 and the alternator 160 are connected to the same rotation shaft 122 to rotate at the same rotational speed.

In the wind generator according to a preferred embodiment of the present invention, the inverter 140 for converting the alternating current output from the alternator 160 into a direct current; A power storage system 150 for storing direct current output from the interleaver; A disc brake to prevent excessive rotation of the generator; And a computer system 170 for controlling the operation of the disc brake and the rotation of the derivative roller 80.

The generator is located in the generator case located between the bottom frame 40 and the intermediate frame 50. The alternator 160 outputs an alternating current using the rotational force.

Inverter 140 converts the alternating current output from the alternator 160 into a direct current. Since the alternating current itself cannot be stored directly, it is necessary to change it to a direct current.

The direct current is not stored as it is, but is converted into chemical energy and stored. The electrical storage system 150 stores electrical energy in a chemical manner. Rechargeable batteries are capable of bidirectional chemical reactions of charging and discharging, so they can store or take out electricity. When the electricity stored in the battery is used at home, the discharge occurs in the battery, and when the electricity is stored by the wind generator again, the charge is performed.

The rotation shaft 122 connected to the second acceleration gear 132 is rotated at a very high speed because the rotation speed is amplified in two stages for high efficiency power generation. Thus, it is possible to use a disc brake and computer system 170 to maintain the proper number of revolutions. If the rotation speed is too high, the disc brake may reduce the rotation speed according to a control command of the computer system 170. In addition, since a lot of heat is generated when the continuous rotation is made, it is possible to have a cooler for lowering the heat. If the temperature is higher than the set temperature, the cooler operates according to the control command of the computer system 170.

It is possible to control the rotation of the derivative roller 80 by the computer system 170. When the DC motor is embedded in the rotating shaft 122 of the rotating roller 84 of the induction roller 80, the rotation of the DC motor is controlled in accordance with a signal transmitted from the computer system 170. The computer system 170 receives a signal input by the wind vane and transmits an output signal to the DC motor.

When excessive wind blows due to a typhoon or the like, the inductor roller 80 may be moved by the computer system 170 in the opposite direction to the windy direction to prevent excessive rotation of the windmill 30.

In the wind generator according to a preferred embodiment of the present invention, a plurality of wind generators are vertically overlapped to form a generator tower 180 in such a way that the lower frame of another wind generator is positioned on the upper frame 60, respectively. The generator tower 180 is connected by a horizontal fixed shaft (181).

As shown in Figure 6, it is possible to configure the generator tower (180).

Wind generators of the present invention can be used to overlap several vertically. That is, when the bottom frame 40 of one wind generator overlaps in a manner coupled with the upper frame 60 of another wind generator, more power is generated by the number of overlaps.

In this case, the plurality of overlapping wind generators form the generator tower 180. When each generator tower 180 is coupled to each other by a horizontal fixed shaft 181 to have a solid structure as a whole, the height of the generator tower 180 can be prevented from occurring left and right flow do.

It is possible to have a lightning rod.

The lightning rod is formed extending from the upper surface of the generator tower 180, and serves to reduce the damage by attracting the impact current of the lightning to the ground. Through the lightning rod, the electricity goes down to the ground along the conductor connected to the lightning rod.
