  In this conventional wind power generation system, an updraft is generated in the air passage 2 due to a difference in atmospheric pressure between the upper floor portion and the lower floor portion, and this updraft rises straight from the lower floor portion toward the opening 5. Therefore, the power of the wind is relatively weak, and there is a problem that the power generation amount is small.

  Therefore, the conventional wind power generation system has problems that must be solved by adding a separate mechanism to dramatically improve the power of the wind and, in turn, increasing the power generation amount. is doing.

  The gist of the present invention for solving the problems of the conventional example is that a high-rise building or a super-high-rise building is provided with a vertical air passage that communicates from a lower floor part to the roof, and the lower floor part communicates with the air passage. An intake is provided, an opening of the air passage is provided in the vicinity of the roof, and a wind power generator and its rotating blades are installed for each predetermined floor of the air passage, and an upward air flow generated in the air passage is A wind power generation system that generates electric power by rotating the rotating blades, wherein a lower half of the rotating blades is provided with a semicircular fixed blade for guiding the updraft to the rotating blade, and the fixed blade Each time it goes up from the first floor to the upper floor, it is installed so as to be shifted by a predetermined angle in a predetermined direction so that the updraft rises in a spiral shape.

  Further, the opening is provided with a rotatable rain avoidance cover, and the open portion of the rain avoidance cover is always directed toward the leeward side by a wind direction sensor, and the air intake and In the opening, a damper for adjusting the air volume is provided, and a ventilation duct in the building is connected to the air path.

According to the wind power generation system of the present invention, the fixed blade for guiding the wind to the rotary blade is provided at the lower portion of the rotary blade, and the fixed blade is predetermined in a predetermined direction every time the fixed blade is raised from the lower floor to the upper floor. By installing it so as to be angularly displaced so that the ascending air current rises in a spiral shape, the wind strikes the rotating blades more strongly, and the rotational efficiency of the rotating blades is greatly improved.
Furthermore, the spiral updraft dramatically increases the power of the wind, can operate the rotating blades on each floor, and can generate electricity on each floor, and can greatly increase the amount of power generation Has the effect.

  In addition, the opening portion is provided with a rotatable rain avoidance cover, and the opening portion of the rain avoidance cover is always directed to the leeward side by the wind direction sensor, thereby preventing intrusion of rainwater, Since the external wind does not directly hit the opening, it is possible to prevent backwind to the wind path. Furthermore, the negative pressure state in the opening can always be maintained, and various excellent effects can be obtained in that an updraft (wind) is easily generated in the air passage.

  And, by providing a damper for adjusting the air volume at the air intake and / or the opening, there is an excellent effect that the air volume can be adjusted in a strong wind or the like.

1 is a schematic cross-sectional view of a high-rise building 12 for explaining a wind power generation system 11 according to the present invention. 3 is a schematic cross-sectional view illustrating the inside of an air passage 14. FIG. 2 is a plan view showing a wind power generator 17 and a rotary blade 18. FIG. (A) (b) (c) It is a top view explaining the installation state of the fixed blade | wing 25. FIG. It is a schematic sectional drawing of high-rise building 1 explaining the wind power generation system which concerns on a prior art example.

  Next, embodiments of the present invention will be described with reference to the drawings. First, in FIG. 1, reference numeral 11 denotes a wind power generation system. The wind power generation system 11 includes a vertical air passage 14 provided in a high-rise building 12 or a high-rise building, and an air intake port 15 communicating with the air passage 14. And an opening 16 of the air passage 14 provided in the vicinity of the rooftop 13, a wind power generator 17 installed on each predetermined floor of the air passage 14, and its rotating blades 18. This is a mechanism for generating electricity by rotating the rotary blade 18.

  The air passage 14 has a predetermined space, is formed in a chimney shape, and communicates in a vertical state from the lower floor portion of the high-rise building 12 to the rooftop 13.

  The air intake 15 is provided at a lower floor portion of the first to third floors and communicates with the air passage 14. Further, a louver plate 15a is disposed at the air intake port 15 to prevent intrusion of rainwater or the like. A net (not shown) is disposed inside the louver plate 15a to prevent entry of small animals and insects.

  An entrance door (not shown) is provided in the vicinity of the air intake 15, and an operator enters the door to perform maintenance or the like.

  As shown in FIG. 2, a damper 19 for adjusting the air volume is disposed in the vicinity of the air intake 15 in the air passage 14, and the air volume can be adjusted by opening and closing the damper 19 during a strong wind. It is. Further, a grating 20 or a net is disposed on the upper portion of the damper 19 to prevent the unnecessary matter from being blown up by the wind.

  The opening 16 is provided with a rising portion 21 (common name: pigeon hut), and a damper 22 for adjusting the air volume is disposed therein. By opening and closing the damper 22, the air volume can be adjusted in a strong wind or the like in combination with the action of the damper 19 described above.

  Further, a rain avoidance cover 23 is provided in the opening 16. A rain avoiding louver plate (not shown) is disposed in the opening 23a of the rain avoiding cover 23 to prevent intrusion of rain water or the like.

  The rain avoidance cover 23 is configured to freely rotate 360 degrees, and is configured such that the open direction 23a is always directed to the leeward side by sensing the wind direction with a wind direction sensor (not shown). Accordingly, not only can rainwater be prevented from entering, but also the external wind does not directly hit the opening 16, so that backwind to the air passage 14 can be prevented. Furthermore, since the negative pressure state in the opening 16 can always be maintained, an updraft (wind) is likely to be generated in the air passage 14.

  As shown in FIG. 2, the wind power generator 17 and the rotary blades 18 are installed for each floor or for each predetermined floor. In addition, the code | symbol 26 in FIG. 2 shows the soundproofing incombustible material arrange | positioned on the wall surface of the air path 14, and the code | symbol 27 shows a floor surface.

  As shown in FIG. 3, the wind power generator 17 is installed on an upper portion of the floor steel material 24, and a grating (not shown) is disposed on the floor steel material 24.

  A rotary blade 18 is provided at the bottom of the floor steel material 24. The rotating blades 18 are rotated by the rising airflow (wind) generated in the air passage 14, and the rotational force is transmitted to the wind power generator 17 to generate power.

Various shapes of the blades of the rotary blade 18 are known. However, the shape is not necessarily limited to the shape shown in FIG. It is possible to appropriately select those that have been used.
Furthermore, the configuration of the wind power generator 17 can be appropriately selected from various types, for example, a type in which permanent magnets and coils are arranged on the periphery of the rotary blade 18 and power is generated by rotation thereof. It is. In short, any structure that generates power using the rotational force of the rotary blade 18 may be used.

  As shown in FIGS. 2 and 4, a semicircular fixed blade 25 is provided below the rotary blade 18. The fixed blade 25 is provided to guide the wind direction so that the wind strikes the rotating blade 18 more strongly, such as a direction in which the wind is substantially orthogonal to the rotating blade 18.

As shown in FIGS. 4 (a), (b), and (c), the fixed blade 25 is installed with an angle shifted by 90 degrees, for example, in the direction of the arrow every time it goes up from the lower floor to the upper floor. Accordingly, the air flow rising up the air passage 14 is guided to the fixed blade 25 and rises in a spiral shape, so that the wind strikes the rotating blade more strongly, and the rotational efficiency of the rotating blade is greatly improved.
Further, the spiral updraft dramatically increases the power of the wind, and can operate the rotary blades on each floor to generate power on each floor and greatly increase the power generation amount.

  In addition, since the fixed blade | wing 25 is formed in semicircle shape, there exists an advantage that it can work by inserting a hand from the lower part side at the time of repair and maintenance of the rotary blade 18.

  A ventilation duct (not shown) in the building is connected to the air passage 14. Therefore, when the outside is in a windless state, it is possible to guide the warm air in the building to the air passage 14, and in this case, an updraft (wind) is likely to be generated in the air passage 14.

  The wind power generation system 11 configured as described above generates power by the following mechanism using the difference in wind speed between the lower floor portion and the vicinity of the rooftop 13. That is, generally, the wind speed is high near the opening 16 of the rooftop 13 and the air intake 15 in the lower floor portion has a low wind speed, so that the air pressure is higher in the air intake 15. Ascending airflow (wind) generated in the air passage 14 due to the pressure difference rotates the rotary blade 18 to drive the wind power generator 17 to generate power.

Each time the fixed blade 25 provided at the lower part of the rotary blade 18 is moved from the lower floor to the upper floor, the angle is shifted by a predetermined angle in the direction of the arrow (FIGS. 4 (A) (B) ( C)), the wind rising up the air passage 14 is guided to the fixed blade 25 and rises spirally. Accordingly, the power of the wind is dramatically increased, and a large amount of power can be generated for each floor.
Note that electricity generated when the power consumption is low such as at night can be stored in a battery (not shown) and used during the daytime when the power consumption is high.
