Description

  The present invention relates to a high-rise building equipped with a power generation system for effectively using wind natural energy for power generation by using strong winds in a high-rise portion of the high-rise building.

  In recent years, in order to reduce carbon dioxide from the viewpoint of environmental conservation, measures for generating power using various natural energies such as sunlight, wind power, geothermal power, and tidal power have been actively promoted.

  Wind power generation, which is a kind of natural energy use, is generally used for the purpose of obtaining a stable wind direction and wind power, such as hills, ridges, coastal areas, etc., where there are no artificial large structures such as buildings around. Is used as a location and a large windmill is installed here.

On the other hand, there is a high possibility that active use of the natural energy will be strongly demanded in the building field in the future.
For this reason, for example, as one of the urban wind power generation, a proposal has been made to install a wind power generation device in the vicinity of a high-rise or super-high-rise building and use the building wind caused by the building, Realization is difficult from the viewpoint of site planning, safety, and landscape.

In urban areas, wind power is weak and the wind direction and wind speed are turbulent.
However, in a high-rise building, when there are few high-rise buildings or super-high-rise buildings in the surrounding area, it is possible to capture strong winds in the sky with relatively little turbulence.

Therefore, as a building equipped with a conventional wind power generation system, one in which a small power generator such as a windmill is installed on the roof of the building has been proposed.
By the way, as shown in FIGS. 14 and 15, a complex air current is generated on the roof top of the building, and it is difficult to obtain a stable wind condition. It is considered desirable to be installed at a position higher than 5m from the roof surface.

  However, in general, there are a building, a cleaning gondola, equipment, helipads, etc. on the roof surface. As a result, the airflow around the roof surface becomes more complicated due to these effects. Since the restrictions on the arrangement are large, it is practically not suitable for the installation location of the power generation device.

  Therefore, in Patent Documents 1 and 2 below, wind turbines are arranged at the upper end portion of the outer wall surface of the building and at the boundary with the roof surface (the roof corner and the outer wall corner). There has been proposed a wind power generator or a power feeding device in which the windmill is rotated by wind rising on the wall surface.

JP 2001-193631 A Japanese Patent Laid-Open No. 11-336340

However, in the conventional wind power generation device or power feeding device, as shown in FIG. 15, the windmill is formed at the boundary between the outer wall surface and the roof surface where the wind direction and wind force tend to fluctuate due to wind separation. Therefore, there is a problem that it is difficult to perform stable and efficient power generation.
In addition, the windmill protruding from the structure is not preferable in view of the scenery, and there is a problem that maintenance such as maintenance and inspection is difficult.

  The present invention has been made in view of the above circumstances, and does not interfere with building plans and landscapes, and is equipped with a power generation system that can efficiently generate power using wind energy. It is an object to provide a high-rise building.

  In order to solve the above-mentioned problem, a high-rise building equipped with the power generation system according to the invention described in claim 1 has an intermediate floor opened in four directions at a position higher than an intermediate position of the height of the high-rise building. In addition to the provision of the wind power generation apparatus, a wind power generation apparatus that generates electric power using wind energy flowing into the intermediate floor is installed on the intermediate floor.

  The invention according to claim 2 is the invention according to claim 1, wherein the intermediate floor is provided at a position of 70 to 80% of the height of the super high-rise building from the ground. It is.

  Furthermore, the invention according to claim 3 is the invention according to claim 1 or 2, wherein the intermediate floor is the largest on the outer wall surface of the high-rise building obtained by airflow simulation or experiment including the neighboring environment. It is provided at a location where positive pressure acts.

  The invention according to claim 4 is characterized in that, in the invention according to any one of claims 1 to 3, a cylindrical core portion is arranged at an outer peripheral corner of the intermediate floor. The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein a plurality of pillars are erected at intervals on the intermediate floor, and a wind turbine generator is provided on the outer periphery of the pillars. A wind turbine serving as a power generator is provided rotatably.

  In addition, although there is no direct definition related to the height of the skyscraper in the Building Standard Law, according to the analogy from Article 20 of the law, in the invention according to any one of claims 1 to 5, Means a building with a height of more than 60 m.

  Generally, a stronger wind force can be obtained at a higher position. And the wind pressure distribution in the skyscraper has the highest positive pressure at the stopping point of the outer wall facing the windward, and the stopping point is usually higher than 1/2 of the height in the skyscraper building. become.

  Therefore, according to the invention described in any one of claims 1 to 5, such a strong wind of wind flows into the intermediate floor, and power can be generated by the wind power generator provided on the intermediate floor. Moreover, since the intermediate floor is open in the four directions, it is possible to always generate power even when the direction of the wind flowing into the intermediate floor changes due to the season or the like.

In addition, since the wind power generator is provided on the intermediate floor, there is no hindrance on the landscape, and further, the maintenance and the like are facilitated because the wind power generator is provided in the building.
Thus, according to the present invention, power generation can be performed efficiently using wind energy throughout the year without obstructing the building plan or landscape.

  Here, according to the analysis result of the wind pressure distribution in the skyscraper with a height exceeding 100 m by the present inventors, the position is approximately 70 to 80% of the height of the skyscraper from the ground, and It has been found that a stopping point where the positive pressure is highest is located at the center in the width direction of the outer wall surface facing the wind direction.

  Therefore, as in the invention described in claim 2, the intermediate floor is provided at a position of 70 to 80% of the height of the super high-rise building from the ground, and a pillar, If the core part which consists of a wall, an EV shaft, a staircase, PS, DS etc. is installed, the said wind can be made to flow in into an intermediate floor from the best position, and is suitable.

  On the other hand, when a similar high-rise building stands around the skyscraper, or when the height of the skyscraper is relatively low, the stop point described above is not always necessary. A case where it is not located at 70 to 80% of the height is also assumed.

  In such a case, as in the invention according to claim 3, the outer wall surface of the above-mentioned high-rise building is analyzed by an analysis of an air flow including an environment such as a neighboring building or topography, or an experiment using a model. If the stop point (maximum positive pressure) is obtained and the intermediate floor is provided at a position that becomes the stop point, the most efficient power generation can be performed.

  Furthermore, when arranging a core part in the outer peripheral corner part of the said intermediate floor, as seen in the analysis result of the inventors etc. mentioned later, the said core part is like the invention of Claim 4. By adopting a columnar shape, even when the wind direction changes, it is possible to generate power more efficiently than when the core portion is configured in a prismatic shape.

  Further, in the intermediate floor, it is necessary to provide columns at a predetermined interval in the central portion due to the span. In such a case, according to the invention described in claim 5, since the wind turbine as the power generator of the wind power generator is rotatably provided on the outer periphery of the pillar, It is suitable because it can be used as a support for a windmill without being obstructed.

  The intermediate floor 2 has a structure in which the core portion 3 having a large outer dimension is disposed at the four corners and the space between the core portions 3 is opened to open in four directions. In addition, a columnar column 4 is disposed in the middle floor 2 with a predetermined span. Each column 4 is provided with a windmill 5 that constitutes a part of the wind turbine generator. Here, the predetermined span is a position where the load on the upper floor is to be supported in the intermediate floor 2 and is determined by an interval with less interference of the influence of the wind on the adjacent wind turbine 5.

  As shown in FIGS. 3 and 4, the wind turbine 5 is composed of a cylindrical main body 6 that is rotatably provided on the outer periphery of the pillar 4, and four blades 7 that project radially from the main body 6. The wings 7 are provided at equal intervals in the circumferential direction of the main body 6.

And in this embodiment, the large-diameter columnar core part 10 is arrange | positioned in the four corner part of the intermediate floor 2. As shown in FIG. In addition, the upper and lower surfaces of the opening of the intermediate floor 2 are also formed as smooth convex curved surfaces.

  In a high-rise building equipped with a power generation system having the above-described configuration, an intermediate floor 2 that opens in four directions is provided at or near the stopping point at which the wind pressure of the high-rise building 1 is highest. In addition, since the wind turbine generator provided with the wind turbine 5 is arranged, the wind turbine 5 is rotated by flowing a strong wind with a stable wind direction into the intermediate floor 2 to efficiently generate power. Can do.

  Moreover, since the middle floor 2 is open in four directions, even when the direction of the wind flowing into the middle floor changes due to the season, etc., power is efficiently generated throughout the year using wind energy. Can do.

In addition, since the wind power generator is provided in the intermediate floor 2, there is no hindrance in terms of scenery, and maintenance of the wind power generator is facilitated.
In addition, since the wind turbine 5 serving as the power generator of the wind power generator is rotatably provided around the pillar 4 provided in the intermediate floor 2, these pillars 4 may hinder the flow of wind. It can also be used as a support for the windmill 5.

  In the above embodiment, the intermediate floor 2 in which the wind power generator is installed is provided at a position 70 to 80% of the height of the super high-rise building 1 from the ground where the stop point where the wind pressure is highest is generally located. However, the present invention is not limited to this. For example, in the case where a similar high-rise building stands around the high-rise building 1, the environment including neighboring buildings and topography is also included. If the stop point (maximum positive pressure) is obtained by analyzing the airflow simulation and the intermediate floor 2 is formed at the stop point, the most efficient power generation can be performed.

  Further, the wind turbine generator provided on the intermediate floor 2 is not limited to the one using the windmill 5 described above, and various forms can be used as long as the energy of the wind flowing through the intermediate floor 2 can be converted into electric power. It is possible to install a wind power generator.

  Next, the inventors have arranged the prismatic core portion 3 as shown in the first embodiment at the four corners of the intermediate floor 2 and the circle as shown in the second embodiment. The difference in the amount of power generated by the same wind power generator when the columnar core portion 10 is arranged was verified by analysis.

  The model used for the analysis is a high-rise building with a width of 40m, a depth of 40m, and a height of 160m with an intermediate floor at 4m from 118m to 122m. The wind speed vector at a position of 120 m in height when the wind having a wind speed of 10 m / s flows into the intermediate layer was obtained.

  7 to 9 are wind velocity vector diagrams showing analysis results when the prismatic core portion 3 is arranged as in the first embodiment. FIG. 7 is a wind direction of 0 °, and FIG. 8 is a wind direction of 22.5. FIG. 9 shows the case where the wind direction is 45 °. 10 to 12 are wind velocity vector diagrams showing analysis results when the cylindrical core portion 10 is arranged as in the second embodiment. FIG. 10 is a wind direction of 0 °, and FIG. 5 ° and FIG. 12 shows a case where the wind direction is 45 °. In any of the drawings, the symbol x is a mark of a virtual position when the wind power generator is installed.

First, in FIG. 7, the wind speed (m / s) at the position indicated by x in the figure is 3.4, 9.2, 2.6 in the clockwise direction of the upper side, the right side, the lower side, and the left side. 10.4.
Similarly, in FIG. 8, the numbers are sequentially 9.4, 8.7, 1.7, and 9.2. In FIG. 9, the numbers are sequentially 9.8, 9.8, 8.0, and 8.1. there were.

  On the other hand, in FIG. 10, it is 9.0, 9.0, 9.8, 12.3 sequentially, and in FIG. 11, it is 9.8, 9.7, 7.2, 11 sequentially. .2. Moreover, in FIG. 12, they were 11.1, 11.1, 10.6, 10.8 sequentially.

  From the above, assuming that the power generation amounts shown in FIGS. 7, 8, and 9 are A, B, and C, respectively, the power generation amount is proportional to the cube of the wind speed. The power generation amounts in the case shown in FIG. 12 are 2.0 A, 1.6 B, and 1.7 C, respectively. Therefore, as in the second embodiment, the cylindrical core portion 10 is formed at the four corners of the intermediate floor 2. It has been found that a higher power generation amount can be obtained by arranging

  Moreover, according to the present invention, a uniform velocity distribution in the height direction can be obtained in the intermediate floor, so that the wind turbine generator is well-balanced, as can be seen in the wind speed vector diagram viewed from the longitudinal section shown in FIG. It has been demonstrated that the wind can act stably.
