Description

  The present invention relates to a building having a wind power generator, and more particularly to a building using a side wall as a wind collecting plate with respect to a wind power generator locked to a column whose top and bottom are fixed.

  Conventionally, wind power generation has attracted attention from the viewpoint of mass consumption of petroleum resources and environmental problems. As a wind power generator, a propeller type system is conventionally known (for example, Patent Document 1). In this system, a tower is installed on a foundation, and a blade composed of a plurality of wings and a generator are provided on the head of the tower. A speed reducer may be appropriately disposed between the blade and the generator.

  This type of wind power generation system has variations such as a vertical axis wind turbine that can generate power regardless of the direction of the wind, a lift type wind turbine that can obtain high-speed rotation, a drag type wind turbine, and a pitch-controlled wind turbine. These windmills were installed in a lot of steep terrain such as windy mountains and remote islands.

  On the other hand, a wind power generation system has been proposed that is installed on a rooftop of a city building or on a high roof, and uses the building wind as energy, and at the same time reduces wind load.

  Patent Document 2 discloses a high-rise building in which a wind passage extending from a wall surface to a roof is provided in a building, and a wind power generator is provided on the roof. A shaft (a perforated hole) is preliminarily installed in the building, and a horizontal hole leading to the shaft is also formed from an opening provided in the wall surface of the building. The wind that hits the building passes through the side hole from this opening, goes up the shaft, goes out of the roof, and turns the wind generator to generate electricity.

Patent Document 3 discloses a vertical axis type wind power generation system in which a rotation axis parallel to the ridge is provided immediately below the roof ridge, and the rotation axis is the vertical axis. Here, a vertical axis type such as a so-called lift type or drag type is used horizontally. And vents are provided under the girders on both sides of the roof. The wind enters from one of the vents, rotates the wind generator inside, and exits from the other vent.

  Propeller-type wind power generators are installed outdoors and are therefore exposed to sunlight and wind and rain. Therefore, it was necessary to use a material excellent in weather resistance. In addition, since it is fixed only by the foundation, strong construction and a tower structure were required to prevent it from collapsing even under strong winds such as typhoons.

  Patent Documents 2 and 3 are designed to install a wind power generator in a building. However, since the purpose is to effectively use the building wind and reduce the wind load, the wind path applied to the wind power generator is effective. It was not what was set.

The present invention has been conceived in order to solve the above problems, and provides a building in which a wind power generator is installed. More specifically,
A building built on the foundation and having a wind generator,
Directly or indirectly on the support material of the building, supported by at least two upper and lower holding points, and vertically arranged struts;
A wind generator between the fixed points and locked to the column;
A ventilation path surrounding the wind power generator and having a wind inlet and a wind outlet;
A building having a wind inlet and a side wall formed around the wind outlet is provided.

  Since this invention is a building which installed the wind power generator in the inside of a building, it can protect a wind power generator from equipment corrosion factors, such as direct sunlight and a wind and rain. In addition, since the wind power generator is locked to the pillars held up and down by the support material of the building, the strength against strong winds such as typhoons can be sufficiently secured.

  In addition, since the side wall of the building is used as a wind collecting wind that is sent to the wind power generator, wind power can be efficiently generated even with a small amount of wind.

  FIG. 1 shows a perspective view of a building in which the wind power generator of the present invention is installed. A building 10 according to the present invention has a foundation 11 on a land, and a building 12 formed of a support material thereon. The building 12 includes a support 50 and a structure in which the wind power generator 60 is locked to the support 50.

  The support material is a member necessary for maintaining the shape of the building, and may be a surface material such as a wall or a slab as well as a wire material such as a square or a log used for columns, beams, and girders. In FIG. 1, the floor 15, the side walls 17, 18, 19, 20 and the roof slab 21 formed on the foundation 11 are the support materials.

  FIG. 2 shows a three-sided view of the building of the present invention. 2A is a plan view, FIG. 2B is a cross-sectional view, and FIG. 2C is an elevation view. A more detailed description is given below with reference to FIGS.

  The building 10 of the present invention can be installed in windy mountains, hills, and coastlines. Moreover, since a building style can be utilized, it can also be installed as a high-rise building. This is because the building of the present invention may coexist not only with a wind power generator but also a living space for people.

  The foundation 11 can be configured by foundation work for ordinary buildings with respect to land. That is, the basis of the present invention is obtained by design and construction in which the load of the entire building is estimated and the ground survey is conducted. Of course, you can comply with Article 38 of the Building Standard Construction Ordinance.

  A floor 15 can be disposed on the foundation 11. Here, the floor 15 is constructed on a foundation and is a horizontal plane. Conventional materials such as concrete, tile, and wood can be used.

  The side walls 17 to 20 are flat members or curved members disposed on the foundation 11 or the floor 15. For example, bricks or blocks may be arranged in a plane or curved surface. The side walls are formed to effectively send wind to the wind power generator. Details of the shape of the side wall will be described later.

  In the present embodiment, the side wall is a support material that supports the ceiling slab 21. However, the side wall may be a member formed between pillars as a support material made of steel frame or wood. That is, the ceiling slab 21 may not be supported.

  A ceiling slab 21 is disposed on the top of the building. A slab is a floorboard made of reinforced concrete. In other words, the slab is arranged for each floor of a building made of reinforced concrete, and becomes a ceiling of a certain floor and is also a floor of an upper floor. Ceiling slab refers to the slab that is placed on the ceiling.

  In the present embodiment, the case where the roof is configured with a slab has been described. However, the roof is not limited to the slab, and a roof material including a ridge, a beam, and a girder may be used.

  The ceiling slab 21 is coupled to the side wall. Therefore, the building of this invention can ensure the intensity | strength as a three-dimensional structure with the side wall installed in the foundation, and the slab which couple | bonds side walls. Of course, in order to ensure the strength of the building, pillars may be arranged at appropriate locations in the building. The slab does not have to be the top surface of the building, and a roof may be disposed on the slab.

  The column 50 is held at one end by the foundation 11, and the other is held by the ceiling slab 21. The support of the support 50 is not particularly limited as long as it supports the weight of the support 50 and the wind power generator 60 locked to the support and can counter the horizontal force applied to the wind power generator.

  When the building has a plurality of floors, the column 50 is not limited to be held only between the foundation 11 and the ceiling slab 21. That is, in the middle floor, you may hold | maintain between the slab used as a floor and the slab used as a ceiling. In that case, the support column 50 may be disposed only between the floor and the ceiling.

  Moreover, the support | pillar 50 may be hold | maintained with the reinforcing material hold | maintained at the support material in the middle of the floor. This is because the purpose of the present invention is to support the horizontal force that the wind power generator receives from the wind by the strength of the building. Therefore, the pillar of the present invention is held directly or indirectly by the support material at the top and bottom of the wind generator at least of the pillar to which the wind generator is locked.

  Also, the strut may itself be rotatable. This is to change the direction of the wind power generator locked to the column.

  Specifically, a bearing structure may be provided in a portion held by the foundation 11 and the ceiling slab 21 so that the column itself can rotate. Moreover, the motor for rotating a support | pillar may be installed in the basement.

  The type of the wind power generator 60 is not particularly limited, but a propeller type can be suitably used. This is because the propeller type that receives wind by the blades arranged on the rotating shaft easily obtains rotational torque, and can be combined with a speed reducer to enable efficient power generation.

  A plurality of wind power generators 60 may be installed in one building. The figure shows a case where three wind power generators are arranged in the vertical direction. When a building becomes high-rise, it is not necessary to install it on successive floors, and it may be installed only on a specific floor.

  The wind power generator 60 may be fixed and locked to the support column 21, or may have a structure capable of rotating itself with the support column 21 as a fixed shaft. Especially when the building is high-rise, the direction of the wind hitting the building may change depending on the height from the ground, and it is more efficient if the wind generators installed at each level can change the direction separately. This is because the wind can be used.

  A ventilation path 30 is constructed around the wind power generator 60. A ventilating path is a wind path that takes wind from the wall of the building and discharges it out of the building again. A wind power generator is arranged in the middle of this ventilation path. The wind passing through the ventilation path rotates the wings of the wind power generator, generating electricity. The ventilation path is composed of a wind inlet 31 and a wind outlet 32 connected to the side walls, and ventilation path walls 33, 34, 39, and 40.

  The air inlet 31 is an opening formed in the side wall 17. The shape is not particularly limited, and the shape can be a square, a rectangle, a circle, an ellipse, or the like. Similarly, the air outlet 32 is an opening formed in the side wall 19. It is preferable that the air inlet 31, the ventilation path 30, and the air outlet 32 are formed on a straight line. This is because the resistance when the wind passes through the ventilation path can be reduced. However, the ventilation path is not necessarily limited to a straight line. The distinction between the wind inlet and the wind outlet is determined by the direction in which the wind enters. When the wind enters from the sign 32, the wind inlet is indicated by reference numeral 32, and the wind outlet is indicated by reference numeral 31.

  A ventilation path wall is a wall that forms a ventilation path. In the building of the present invention, wind collected at the side wall is caused to flow through a wind path, and wind power is generated by the wind. Therefore, in order to flow the collected wind to the wind power generator, an inner wall is required in the ventilation path.

  In FIG. 2, the air passage is composed of a slab that forms a floor 40 and a ceiling 39, and vertical walls 33 and 34 inside the building. In this way, the ventilation path may not be formed of a dedicated material, but may also be part of the structure of the building.

  The ventilation path wall may have an opening in addition to the wind inlet and the wind outlet. This is because in the building of the present invention, the wind power generator is installed inside the building, and therefore wind power generation can be performed more efficiently by providing a plurality of directions of the ventilation path.

  Referring to FIG. 2A, a second ventilation path is formed in a direction perpendicular to the first ventilation path including the front wind inlet 31. The second ventilation path is a ventilation path that passes from the opening 36 of the side wall 18 through the reference numerals 34 and 33 to the opening 38 of the side wall 20. This is because the wind from the side of the building causes wind power generation through the second ventilation path. When the second ventilation path is used, the wind power generator 60 faces the direction of the opening 36 or 38.

  In addition, it is desirable to close the wind inlet and the wind outlet of the unused ventilation path with a shutter or the like. In FIG. 2A, when the first air passage is used, 33 and 34 constituting the air inlet and the air outlet of the second air passage are each closed by a shutter. This is because when the wind flowing in from the wind inlet escapes in the lateral direction, a wind that does not rotate the blades of the wind power generator is generated, and the power generation efficiency decreases.

  Moreover, you may enable it to close the shutter of all the ventilation paths. This is because there is a case where it is not desired to apply wind to the wind power generator. Specifically, it is during maintenance work or when the wind speed is too high due to a typhoon or the like.

  A wind direction plate 51 may be installed on the roof of the building of the present invention. The wind direction plate is a plate that faces the direction of the wind, and is obtained by forming a pivot at a point away from the symmetry axis of the plate-like material. When the wind hits the wind direction plate, the short side from the axis of symmetry always faces upwind due to the difference in rotational moment about the pivot axis.

  The wind direction plate may be directly coupled to the rotatable support column 21 to rotate the support column. This is to direct the wind power generator upwind. However, the rotation moment of the support with the wind power generator locked is heavy, and it is difficult to rotate with a small amount of wind power. Moreover, the wind power generator installed in the building of this invention cannot receive the wind from arbitrary directions. For example, the building shown in FIG. 1 or 2 can receive only wind from two directions (or four directions) basically.

  Therefore, the wind direction plate may be rotated separately from the support column. In this case, it is desirable to provide an angle sensor on the pivot of the wind direction plate so that the wind direction can be extracted as an electrical signal. This is because it is possible to select and control which ventilation path is used depending on the wind direction.

  Next, the wind power generation operation | movement of the building of this invention is demonstrated. Referring to FIG. 2A, the side wall 17 on the front surface of the building is formed in a shape that is recessed toward the wind inlet 31. The wind hitting the front of the building enters the wind inlet 31 along the shape of the dent, rotates the wind power generator 60, passes through the ventilation path, and exits from the wind outlet 32 to the outside of the building. Thus, the building of this invention may utilize the shape of a side wall for wind collection. The shape given to the side wall for collecting air is called the collected air shape.

  FIG. 3 illustrates another shape of the side wall. Fig.3 (a) shows the shape dented linearly toward a wind inlet. Also, FIG. 3B shows a shape that is recessed with a curvature opposite to that of FIG. Moreover, the shape of these wall surfaces may have not only a top view but cross-sectional shape. In addition, although the case where the wind collection shape was provided only to one surface of the building was demonstrated here, the wind collection shape may be formed in any surface.

  In FIG. 4, the variation of the building of this invention at the time of making a side wall only for the purpose of wind collection is shown. The ventilation path is formed in two directions, and the side wall in each direction has a shape that becomes narrower toward the wind inlet. FIG. 5A shows a cross-sectional view.

  The side walls 70 to 73 are walls arranged toward the ventilation path 30, and serve as a wind collecting plate that collects wind toward the wind inlets (or wind outlets) 31 to 34. Depending on the direction of the wind, the signs 33 and 34 or the signs 31 and 32 are closed with a shutter to form an air passage.

  In such an embodiment, the building is not limited to a square cross section. FIG. 5B shows a case where the cross section of the building is circular. Here, a three-way ventilation path is formed by the side walls 75 to 80. Specifically, the shutters 81 and 84 and the shutters 83 and 86 are closed, the first ventilation path for opening the shutters 82 and 85, the shutters 81 and 84 and the shutters 8 and 85 are closed, and the shutters 83 and 86 are opened second. And the third ventilation path that closes the shutters 82 and 85 and the shutters 83 and 86 and opens the shutters 81 and 84.

The present invention can be used not only as a building having a wind power generator but also as a wind power generator itself.

It is a perspective view of the building of this invention. It is a three-sided view of the building of the present invention. It is a figure which illustrates the shape of the side wall of this invention. It is a figure which illustrates the shape of the side wall of this invention.
