Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wind turbine generator using a wind turbine propeller, and more particularly to a wind turbine generator that does not require direction control of a wind turbine propeller and can generate power even with small wind power.
[0002]
[Prior art]
The wind turbine generator rotates a wind turbine propeller using natural wind power, drives a generator with the power of rotating the wind turbine propeller, and takes it out as electric energy.
[0003]
As a general wind power generator, a horizontal shaft type in which the rotation axis of the wind turbine propeller is oriented parallel to the wind direction is used, and in particular, the wind turbine propeller has three blades as the main force. Yes.
[0004]
When converting wind energy into electrical energy with this wind power generator, an anemometer and anemometer are installed to check the wind force and wind direction, and the wind is captured while controlling the direction of the wind turbine propeller according to this wind direction. Power generation.
[0005]
[Problems to be solved by the invention]
However, in order to always control the direction of the wind turbine propeller with respect to the wind direction, in addition to the anemometer and anemometer, a direction control device and a power unit are necessary. Conversion efficiency was low.
[0006]
Also, since the wind energy is proportional to the cube of the wind speed, for example, the wind turbine propeller cannot be rotated by the wind energy unless at least the wind of 6 m / s is blown. Could not generate power stably.
[0007]
Accordingly, an object of the present invention is to provide a wind power generator that does not require direction control of a wind turbine propeller and can generate power even at a low wind speed.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a central support column, a concrete support wall is erected radially around the central support column, and a wire is stretched between the central support column and each concrete support wall. Support the central strut, set up the outer struts on the extension line extending from the central strut through the concrete support wall, and make the tent cloth wall-like between each outer strut and the central strut or the concrete support wall. Tent cloth wall is formed by tension, and the top of the outer support column is pulled outward with a wire and fixed, and a triangular suspended tent cloth is provided between the adjacent tent cloth walls in the circumferential direction, and one corner is formed on the center support column. It is fixed to the top and the other two corners are fixed to the bottom of the outer struts adjacent in the circumferential direction, and the upper end on the outer peripheral side of the tent cloth wall adjacent in the circumferential direction is covered with a roof, respectively. A wind inlet opening radially outward is formed between the outer struts and a wind outlet opening upward is formed between the upper ends of the concrete support walls, and a cylinder is formed on the concrete support wall as the wind outlet. The wind turbine propeller is installed in communication with the wind turbine prop, and a generator is connected to the rotating shaft of the wind turbine propeller .
[0009]
According to the above arrangement, since the air that has been taken whether we wind inlet is always facing upward in the cylinder body, the direction control device and a driving device is not necessary. In addition , since the taken-in wind is converged and speeded up, the minimum wind speed for power generation is lowered and stable power generation is possible.

[0013]
As shown in FIG. 1 (b), the wind intake booth 30 includes eight guide cells 15 provided to partition each of the wind intake ports 20 to the air outlets 28, and the top of these guide cells 15. As shown in FIG. 1 (a), it comprises a donut-shaped roof 29 having a wind outlet 28 formed at the center. The guide cells 15 that divide between the guide cells 15 and 15 and extend radially from the center of the booth 30 include a concrete support wall 22 having a side wall provided on the inner peripheral side thereof and a tent cloth wall 26 provided on the outer peripheral side thereof. In addition, the bottom portion is formed of a triangular hanging tent cloth 27 that changes the wind taken from each wind intake port 20 to flow upward.
[0014]
In addition, the cylindrical body 35 is formed in a cylindrical shape, and is erected on the upper part of the above-described concrete support wall 22 so as to communicate with the wind outlet 28. Inside the cylindrical body 35, the wind passing through the cylindrical body 35 is provided. The wind turbine propeller 40 is provided downward so as to face the wind turbine propeller 40, and the generator 50 is coupled to the rotating shaft of the wind turbine propeller 40. Further, the wind turbine propeller 40 has a cone 45 so that the wind does not hit the central portion thereof. A vent 55 is provided at the upper portion of the cylindrical body 35 for removing the wind passing through the cylindrical body 35 and preventing rain water from entering the cylindrical body 35.
[0015]
When assembling the wind-intake booth 30, as shown in FIG. 2, first, one central column 21 having a predetermined height is erected, and the central column 21 is spaced from the central column 21 by a predetermined interval. 8 concrete support walls 22 are erected radially at equal intervals. Next, a wire 24 is stretched from the central support 21 to the concrete support wall 22 to support the central support 21. And the outer support | pillar 23 is erected on the extension line from this center support | pillar 21 via the concrete support wall 22 with a predetermined space | interval from the center support | pillar 21. As shown in FIG.
[0016]
Next, as shown in FIG. 3, the top portions of the outer support columns 23 are pulled and fixed to the outside with wires 25, and the outer support columns 23 provided in eight directions from the central support column 21 (or the concrete support wall 22). A tent cloth wall 26 is formed by stretching the tent cloth over the space, and the peripheral ends of these tent cloths are fixed to the central column 21 (or the concrete support wall 22) and the outer column 23. Then, the above-mentioned suspended tent cloth 27 is provided between the eight tent cloth walls 26, the top part thereof is fixed to the top part of the central support column 21, and the two bottom parts are fixed to the bottom parts of the outer support columns 23 and 23, thereby guiding cells. 15 is formed. Finally, the upper opening portions of the guide cells 15 are closed with a roof 29, and the wind intake port 20 is formed in the entire circumferential direction of the wind intake booth 30, and the wind outlet port 28 is formed in the central portion of the roof 29. .
[0017]
Next, the operation of the wind power generator of the present invention will be described with reference to FIG.
[0018]
The wind taken from one wind take-in port 20 is guided to the center of the wind take-up booth 30 by the guide cell 15 and is converged and increased in speed to flow in the direction of the arrow w. The upward wind passes through the air outlet 28 and rises in the cylindrical body 35, hits the blades of the windmill propeller 40, and rotates the windmill propeller 40. And the generator 50 is driven by rotation of this windmill propeller 40, and the energy of a wind is converted into an electrical energy. Thereafter, the wind rotating the windmill propeller 40 escapes from the vent 55.
[0019]
In addition, the wind taken in from the other wind inlet 20 is similarly guided into the cylindrical body 35, and the wind turbine propeller 40 is rotated to generate power and then escape from the vent 55.
[0020]
In other words, the wind turbine propeller 40 is rotated as described above to generate power regardless of the direction of wind around the wind power generator 10 of the present invention.
[0021]
As described above, the wind taken into the wind power generator 10 of the present invention can generate electric power by rotating the wind turbine propeller 40 while increasing the speed regardless of the direction. A driving device is not required, and even if the wind taken into the device 10 is low in speed, the speed is increased several times in the cylindrical body 35, so that energy can be easily taken out. Therefore, the wind turbine propeller 40 can be miniaturized and the generator 50 can be miniaturized.
[0022]
Further, the wind taken into the wind turbine generator 10 of the present invention is configured to lift the wind turbine propeller 40 from below, and the friction generated between the rotating shaft of the wind turbine propeller 40 and the bearing of the rotating shaft is reduced. Can be reduced.
[0023]
Furthermore, since the wind take-up booth 30 is formed by the tent cloths 26 and 27, the poles 21 and 23, and the wires 24 and 25, the power generation cost is low, and the tent cloth may be folded during a typhoon.
[0024]
In the present embodiment, the wind inlets 20 are provided in eight directions. However, as the number of the wind inlets 20 is increased, the amount of air introduced increases and the energy between the wind inlets 20 and 20 increases. In consideration of the increase in loss, the number of wind inlets 20 may be increased as appropriate. However, if the direction of taking in the wind is less than 6 directions, the amount of air taken in obviously decreases. Therefore, it is preferable to provide a wind intake port so as to take in the wind from at least 6 directions.
[0025]
Further, by forming the cylinder 35 longer in the longitudinal direction and providing the vent 55 at a higher position, an effect of drawing out the wind in the cylinder 35 from the vent 55 and increasing the speed, the so-called Venturi effect can be expected.
[0026]
【The invention's effect】
In short, according to the present invention, since the wind direction is upward in the cylinder regardless of the direction in which the wind is taken, the direction control device and its driving device are not required.
[0027]
In addition, Installing elaborate wind because they are accelerated is converged, it is easy to take out of even at low wind speed energy.
