垂直型風力発電装置Vertical wind power generator
　本発明は風力発電装置に関し、より詳しくは、垂直型風力発電装置に関する。 The present invention relates to a wind power generation device, and more particularly to a vertical wind power generation device.
　昨今、地球温暖化に起因する気候変動の影響が世界各地でみうけられる。このような状況下、地球温暖化の一因である温室効果ガスの排出ゼロを実現すべく、再生可能エネルギーの導入促進が求められている。 Recently, the effects of climate change caused by global warming are being felt all over the world. Under these circumstances, there is a need to promote the introduction of renewable energy in order to achieve zero emissions of greenhouse gases, which are a cause of global warming.
　従来、風力発電装置として、鉛直方向に延びる回転軸に八枚の放射状のブレードが設けられた縦軸型（垂直型）の風力発電装置（特許文献１）が知られている。 Conventionally, as a wind power generation device, a vertical axis type (vertical type) wind power generation device (Patent Document 1) is known, in which eight radial blades are provided on a rotating shaft extending in the vertical direction.
特開２００５－３３７２４５号公報Japanese Patent Application Publication No. 2005-337245
　ところで、風力発電装置については、設置場所の問題や騒音の問題、生態系への影響、強風時のブレードの破損等の問題が指摘されており、これらの問題を解決できる技術の提案が望まれている。 By the way, problems have been pointed out regarding wind power generators, such as installation location problems, noise problems, impact on the ecosystem, and blade damage during strong winds, and proposals for technologies that can solve these problems are desired. ing.
　本発明はかかる事情に鑑みてなされたものであり、その解決課題は、従来の垂直型風力発電装置に比べて、設置場所の自由度が高く、騒音や生態系への影響が少なく、強風時のブレードの破損リスクが低い垂直型風力発電装置を提供することにある。 The present invention was made in view of the above circumstances, and the problems to be solved are that compared to conventional vertical wind power generators, there is a higher degree of freedom in the installation location, less noise and impact on the ecosystem, and a system that can be used even during strong winds. An object of the present invention is to provide a vertical wind power generation device with a low risk of blade breakage.
　本発明の垂直型風力発電装置は、錐体状の外側構造体と、外側構造体の内側に回転可能に設置された動力伝達軸と、動力伝達軸に設けられた受風面を有する受風手段と、動力伝達軸に連結された発電機を備えたものである。 The vertical wind power generation device of the present invention includes a conical outer structure, a power transmission shaft rotatably installed inside the outer structure, and a wind receiving surface provided on the power transmission shaft. and a generator connected to a power transmission shaft.
　前記構成を備えた本発明の垂直型風力発電装置では、過剰な風を錐体状の外側構造体に沿って逃がすことができるため、従来の垂直型風力発電装置に比べて強風時のブレードの破損リスクを抑えることができる。また、受風手段が外側構造体の内側に設けられているため、騒音や生態系への影響が少なくすることができる。本発明の垂直型風力発電装置は小型化可能な構造であるため、設置場所の自由度も高い。 In the vertical wind power generation device of the present invention having the above configuration, excess wind can be released along the cone-shaped outer structure, so the blades are more stable during strong winds than in conventional vertical wind power generation devices. Damage risk can be reduced. Furthermore, since the wind blowing means is provided inside the outer structure, noise and the impact on the ecosystem can be reduced. Since the vertical wind power generation device of the present invention has a structure that can be downsized, it has a high degree of freedom in installation location.

　（実施形態）
　本発明の垂直型風力発電装置の実施形態の一例を、図面を参照して説明する。一例として図１に示す垂直型風力発電装置は、発電機１０と、動力伝達軸２０と、受風手段３０と、外側構造体４０と、風取込み手段５０（図３（ｃ）及び図４（ａ）等）を主要構成として備えている。 (Embodiment)
An example of an embodiment of a vertical wind power generation device of the present invention will be described with reference to the drawings. As an example, the vertical wind power generation device shown in FIG. a) etc.) as the main components.
　前記発電機１０は、回転運動を電気に変換する装置（ジェネレータ）である。発電機１０には、新規の又は既存のものを用いることができる。 The generator 10 is a device (generator) that converts rotational motion into electricity. The generator 10 can be new or existing.
　前記発電機１０には動力伝達軸２０が連結されている。動力伝達軸２０は後述する受風手段３０による回転力を発電機１０に伝達する部材である。この実施形態の動力伝達軸２０は発電機１０に対して垂直な縦長の柱状であり、その下端側が発電機１０に連結されている。動力伝達軸２０の上端側は軸受２１で回転可能に支持されている。 A power transmission shaft 20 is connected to the generator 10. The power transmission shaft 20 is a member that transmits rotational force generated by a wind blowing means 30 (described later) to the generator 10. The power transmission shaft 20 of this embodiment has a vertical column shape perpendicular to the generator 10, and its lower end side is connected to the generator 10. The upper end side of the power transmission shaft 20 is rotatably supported by a bearing 21.
　前記受風手段３０は、風を受けて動力伝達軸２０を回転させる部材である。この実施形態では、複数の受風手段３０が動力伝達軸２０の垂直方向に間隔をあけて複数段設けられている。各段の受風手段３０は複数枚のブレード３１で構成され、それぞれを独立したユニットとして取り扱うことができる。 The wind receiving means 30 is a member that rotates the power transmission shaft 20 by receiving wind. In this embodiment, a plurality of wind blowing means 30 are provided in a plurality of stages at intervals in the vertical direction of the power transmission shaft 20. The wind blowing means 30 at each stage is composed of a plurality of blades 31, each of which can be handled as an independent unit.
　この実施形態では、各受風手段３０を構成するブレード３１の枚数を奇数枚としてある。偶数枚を均等間隔で設けた場合、ある方向からの風を受けた際に、平面視同一直線上にあるブレード３１同士で回転力を打ち消し合い、受風量が小さくなるおそれがある。 In this embodiment, the number of blades 31 constituting each wind blowing means 30 is an odd number. If an even number of blades are provided at equal intervals, when wind blows from a certain direction, the rotational force of the blades 31 that are on the same straight line in a plan view may cancel each other out, which may reduce the amount of air received.
　これに対し、ブレード３１の枚数を奇数枚とすることで、同一軸線上に二枚のブレード３１が並ばなくなるため、回転力の打ち消し合いが起こりにくく、動力伝達軸２０が回転しやすくなるというメリットがある。奇数枚のブレード３１は、回転力の打ち消し合いを起こさない限り、均等間隔で設けることも不均等間隔で設けることもできる。 On the other hand, by setting the number of blades 31 to an odd number, two blades 31 are not lined up on the same axis, which has the advantage that the rotational forces are less likely to cancel each other out, making it easier for the power transmission shaft 20 to rotate. There is. The odd number of blades 31 may be provided at equal or uneven intervals as long as the rotational forces do not cancel each other out.
　回転力の打ち消し合いが起こりにくい構造であれば、各受風手段のブレード３１の枚数は偶数枚とすることもできる。たとえば、ブレード３１の設置間隔を不均等間隔とすることで偶数枚であっても回転力の打ち消し合いを起こりにくくすることができる。 The number of blades 31 of each wind blowing means may be an even number as long as the structure is such that the rotational forces are unlikely to cancel each other out. For example, by setting the blades 31 at uneven intervals, even if there is an even number of blades, it is possible to make it difficult for the rotational forces to cancel each other out.
　その他、受風手段３０を構成する複数枚のブレード３１の形状を異なる形状とすることで、ブレード３１の枚数が偶数枚であるか奇数枚であるかを問わず、回転力の打ち消し合いを起こりにくくすることができる。 In addition, by making the shapes of the plurality of blades 31 that constitute the wind blowing means 30 different, the rotational forces cancel each other out regardless of whether the number of blades 31 is an even number or an odd number. It can be made difficult.
　要するに、複数枚のブレード３１で構成される各受風手段３０の構造が、点対称とならないような構造、具体的には、動力伝達軸２０のうちブレード３１の高さ方向及び水平方向の中心点を対称点として、各受風手段３０の構造が非点対称な構造であれば、ブレード３１による回転力の打ち消し合いを起こりにくくすることができる。 In short, the structure of each wind blowing means 30 composed of a plurality of blades 31 is not point symmetrical, specifically, the center of the blade 31 in the power transmission shaft 20 in the height direction and horizontal direction. If the structure of each wind blowing means 30 is asymmetrical with respect to the point of symmetry, it is possible to make it difficult for the rotational forces of the blades 31 to cancel each other out.
　この実施形態のブレード３１は垂直な受風面（垂直受風面）を備えた横長方形状であり、フラットなベース部３１ａの先端側に屈折部３１ｂが設けられている。この実施形態では、屈折部３１ｂのベース部３１ａに対する屈折角度を４５度としてあるが、この角度は４５度以外であっても良い。受風面は垂直でなくてもよく、垂直面を仮想した場合にその仮想の垂直面に対して角度を持って設けることもできる。 The blade 31 of this embodiment has a horizontal rectangular shape with a vertical wind receiving surface (vertical wind receiving surface), and a bent portion 31b is provided on the tip side of a flat base portion 31a. In this embodiment, the refraction angle of the refraction portion 31b with respect to the base portion 31a is set to 45 degrees, but this angle may be other than 45 degrees. The wind receiving surface does not need to be perpendicular, and in the case of an imaginary vertical surface, it can be provided at an angle with respect to the imaginary vertical surface.
　この実施形態では、受風手段３０を構成するブレード３１の横方向の長さを段ごとに異なる長さとしてある。具体的には、下段側の受風手段３０を構成するブレード３１の長さが、上段側の受風手段３０を構成するブレード３１の長さよりも横方向に長くなるようにしてある。 In this embodiment, the length in the lateral direction of the blades 31 constituting the wind blowing means 30 is set to be different for each stage. Specifically, the length of the blade 31 constituting the lower wind blowing means 30 is made longer in the lateral direction than the length of the blade 31 constituting the upper wind blowing means 30.
　別の言い方をすれば、ブレード３１の上下方向（高さ方向）の寸法を一定とした場合、上段側のブレード３１ほど受風面積が狭く、下段側のブレード３１ほど受風面積が広くなるようにしてある。 In other words, if the dimensions of the blades 31 in the vertical direction (height direction) are constant, the upper blades 31 have a narrower wind-catching area, and the lower blades 31 have a wider wind-catching area. It is set as.
　ブレード３１の長さをこのように設定した場合、動力伝達軸２０及び受風手段３０を正面から見た場合に、下側ほど幅が広く、上側に向けて次第に幅が狭くなるようなツリー状の形状、換言すれば、縦向きのタービンのような形状となる。 When the length of the blade 31 is set in this way, when the power transmission shaft 20 and the wind blowing means 30 are viewed from the front, they form a tree shape in which the width is wider toward the bottom and gradually narrows toward the top. In other words, it has a vertical turbine-like shape.
　なお、各受風手段３０を構成するブレード３１の枚数に特に限定はない。また、各段の受風手段３０のブレード３１は、同じ枚数とすることも異なる枚数とすることもできる。異なる枚数とする場合、すべての受風手段３０のブレード３１を異なる枚数とすることも、一部の受風手段３０のブレード３１を異なる枚数とすることもできる。 Note that the number of blades 31 constituting each wind blowing means 30 is not particularly limited. Further, the number of blades 31 of the wind blowing means 30 at each stage can be the same or different. When the number of blades is different, the number of blades 31 of all the wind blowing means 30 can be different, or the number of blades 31 of some of the wind blowing means 30 can be different.
　図示は省略しているが、必要に応じて、受風手段３０の逆回転を防止するストッパーや、逆回転を強制的に正回転に変換するギヤなどを設けることもできる。 Although not shown in the drawings, a stopper that prevents the wind blowing means 30 from rotating in reverse, a gear that forcibly converts reverse rotation into forward rotation, or the like may be provided as necessary.
　各受風手段３０の上下には整流体３２が設けられている。便宜上、図１では最上段の受風手段３０の上側の整流体３２と、最下段の受風手段３０の下側の整流体３２のみを示しているが、この実施形態では、各受風手段３０の間、最上段の受風手段３０の上側及び最下段の受風手段３０の下側の各所に整流体３２を設けてある。 A flow regulator 32 is provided above and below each wind blowing means 30. For convenience, FIG. 1 only shows the flow regulating fluid 32 above the uppermost wind blowing means 30 and the lower flow regulating flow 32 of the lowermost wind blowing means 30, but in this embodiment, each wind blowing means 30, flow regulators 32 are provided at various locations above the uppermost wind blowing means 30 and below the lowermost wind blowing means 30.
　整流体３２は、取り込んだ風が上下に抜けることなくブレード３１の垂直受風面に当たるように風の流れを整えるものであり、たとえば、円板状や方形状の板材等を用いることができる。整流体３２には、円形状や方形状の板材のほか、楕円形状等の任意形状の板材等を用いることもできる。場合によっては、一部が湾曲した板材や一部が切り欠かれた板材等を整流体３２として用いることもできる。また、整流体３２は板材でなくても良い。整流体３２として板材を用いる場合、図１に示すように、動力伝達軸２０に交差する向き（たとえば、動力伝達軸２０に直交する向き）に設けることができる。 The flow regulator 32 adjusts the flow of the air so that it hits the vertical wind receiving surface of the blade 31 without passing upward or downward, and can be made of, for example, a disc-shaped or rectangular plate. In addition to a circular or rectangular plate, a plate of any shape such as an ellipse may be used for the flow regulator 32. Depending on the case, a partially curved plate material, a partially cut-out plate material, or the like may be used as the flow regulator 32. Moreover, the flow regulator 32 does not need to be a plate material. When a plate material is used as the flow regulator 32, as shown in FIG. 1, it can be provided in a direction intersecting the power transmission shaft 20 (for example, in a direction perpendicular to the power transmission shaft 20).
　この実施形態では、各受風手段３０の間に一枚ずつ整流体３２を設けているが、各受風手段３０の間に二枚以上の整流体３２を設けることもできる。このほか、整流体３２は最上段の受風手段３０の上側と最下段の受風手段３０の下側にのみ設ける等、任意の受風手段３０の間にのみ設けることもできる。 In this embodiment, one rectifier 32 is provided between each of the wind blowing means 30, but two or more rectifiers 32 may be provided between each wind blowing means 30. In addition, the flow regulator 32 can also be provided only between any of the wind blowing means 30, such as only above the uppermost wind blowing means 30 and below the lowermost wind blowing means 30.
　前記外側構造体４０は発電機１０や動力伝達軸２０、受風手段３０の外側を覆う部材である。外側構造体４０は鳥等の動物やその他の飛来物が受風手段３０等にぶつかるのを防止するための部材であり、後述する風取込み手段５０を支えるための部材である。 The outer structure 40 is a member that covers the outside of the generator 10, the power transmission shaft 20, and the wind blowing means 30. The outer structure 40 is a member for preventing animals such as birds and other flying objects from colliding with the wind blowing means 30, etc., and is a member for supporting the wind intake means 50, which will be described later.
　この実施形態の外側構造体４０は、上端側に向けて先細りの略三角錐状の構造体である。外側構造体４０は、三角錐状以外の角錐状や円錐状等、三角錐以外の錐体状とすることもできる。外側構造体４０は、三角錐状や円錐状の錐体の頂部側が底面と平行な平面で切断された截頭錐体状とすることもできる。 The outer structure 40 of this embodiment is a substantially triangular pyramid-shaped structure that tapers toward the upper end. The outer structure 40 may also have a pyramidal shape other than a triangular pyramid, such as a pyramidal shape or a conical shape. The outer structure 40 may also be in the shape of a truncated pyramid, such as a triangular pyramid or a cone whose top side is cut by a plane parallel to the bottom surface.
　本願において、「錐体状」とは、三角錐状やその他の角錐状、円錐状等のほか、これらの頂部側が底面と平行な平面で切断された截頭錐体状を含む概念である。 In this application, the term "pyramid shape" is a concept that includes triangular pyramid shapes, other pyramid shapes, conical shapes, etc., as well as truncated pyramid shapes whose top sides are cut by a plane parallel to the bottom surface.
　外側構造体４０を三角錐状や円錐状などの錐体状とした場合、図３（ａ）に点線で示すように外側構造体４０の傾斜面に沿って風を逃がすことができるため、過剰な風の侵入や受風を回避し、ブレード３１や動力伝達軸２０、外側構造体４０等の倒壊や破損等のリスクを低減することができる。外側構造体４０の形状を外圧に強い性質を有する三角形状（三角錐状）とした場合には、特にその効果が大きい。 When the outer structure 40 has a conical shape such as a triangular pyramid shape or a conical shape, wind can escape along the slope of the outer structure 40 as shown by the dotted line in FIG. This makes it possible to avoid wind intrusion or wind blowing, and reduce the risk of collapse or damage to the blade 31, the power transmission shaft 20, the outer structure 40, etc. This effect is particularly great when the shape of the outer structure 40 is a triangular shape (triangular pyramid shape) that is resistant to external pressure.
　この実施形態では、強い風を受けても倒壊や破損等しないように、外側構造体４０を風が通過する通気口４１と複数のトラス構造を備えたメッシュ構造体としてある。この実施形態の外側構造体４０は、三本の支柱とメッシュ材を組み合わせて截頭の三角錐状の外側構造体４０を構成している。 In this embodiment, the outer structure 40 is a mesh structure including a ventilation hole 41 through which wind passes and a plurality of truss structures so as to prevent it from collapsing or being damaged even when exposed to strong winds. The outer structure 40 of this embodiment has a truncated triangular pyramid shape by combining three pillars and a mesh material.
　前記外側構造体４０の構成は一例であり、これ以外の構成とすることもできる。たとえば、図２（ａ）のように複数本の長尺部材を斜めの格子状に組み合わせたものや、図２（ｂ）のような孔開きの面状部材などによって構成することもできる。いずれの場合も、風が通過する通気口４１を備えている。 The configuration of the outer structure 40 is merely an example, and other configurations may also be used. For example, it may be constructed by combining a plurality of elongated members in a diagonal lattice shape as shown in FIG. 2(a), or a planar member with holes as shown in FIG. 2(b). In either case, a vent 41 through which wind passes is provided.
　外側構造体４０の材質は特に限定されないが、後述する風取込み手段５０を設ける場合には、風取込み手段５０を支えられる程度の強度及び硬度を備える材質製とするのが好ましい。また、後述する付着防止手段６０を設ける場合、外側構造体４０は打撃具６２での打撃によって振動する材質製とするのが好ましい。 The material of the outer structure 40 is not particularly limited, but when a wind intake means 50 described below is provided, it is preferably made of a material that has enough strength and hardness to support the wind intake means 50. Further, when providing an adhesion prevention means 60 to be described later, the outer structure 40 is preferably made of a material that vibrates when struck by the striking tool 62.
　この実施形態では、外側構造体４０に、その内部に風を取り込むための風取込み手段５０が設けられている。風取込み手段５０は風力集中機能と整流機能を備えたターボ器である。一例として図３（ａ）～（ｃ）に示す風取込み手段５０は、いわゆる風レンズ形状の構造体であり、外側構造体４０に複数個取り付けられている。 In this embodiment, the outer structure 40 is provided with a wind intake means 50 for introducing wind into its interior. The wind intake means 50 is a turbo machine having a wind concentration function and a rectification function. As an example, the wind intake means 50 shown in FIGS. 3(a) to 3(c) are so-called wind lens-shaped structures, and a plurality of them are attached to the outer structure 40.
　図３（ｃ）に示すように、この実施形態の風取込み手段５０は円形リング状であり、一面側の周縁がラッパ状に広がった形状をしている。この風取込み手段５０は、その構造上、径の小さな口（以下「小径口」という）５１から取り込んだ風を径の大きな口（以下「大径口」という）５２から排出することで取り込んだ風が増幅される。 As shown in FIG. 3(c), the wind intake means 50 of this embodiment has a circular ring shape, and the peripheral edge on one side is shaped like a trumpet. Due to its structure, this wind intake means 50 takes in wind from a small-diameter opening (hereinafter referred to as "small-diameter opening") 51 and discharges it from a large-diameter opening (hereinafter referred to as "large-diameter opening") 52. The wind is amplified.
　図３（ａ）に示すように、外側構造体４０には複数個の風取込み手段５０が取り付けられている。この実施形態では、各段の受風手段３０を構成するブレード３１に集中的に風を送れるように、外側構造体４０のうち、内側にある受風手段３０の高さと同じ高さに設けられている。 As shown in FIG. 3(a), a plurality of wind intake means 50 are attached to the outer structure 40. In this embodiment, the blades 31 of the outer structure 40 are provided at the same height as the inner wind blowing means 30 so that the wind can be sent intensively to the blades 31 constituting the wind blowing means 30 of each stage. ing.
　風取込み手段５０は、各段の周方向に沿って複数個ずつ設けてある。この構造の風取込み手段５０は、小径口５１が外側を向き、大径口５２が内側を向くように取り付けられる。 A plurality of wind intake means 50 are provided along the circumferential direction of each stage. The wind intake means 50 having this structure is installed such that the small diameter opening 51 faces outside and the large diameter opening 52 faces inside.
　ここで示した風取込み手段５０は一例であり、風取込み手段５０には風レンズ形状のもの以外のものを用いることもできる。たとえば、図４（ａ）に示すように、管部材５３の内部に整流網５４を備えたもの等を用いることもできる。この構造の風取込み手段５０は、図４（ｂ）に示すように、大径口５５が外側を向き、小径口５６が内側を向くように取り付けられる。 The wind intake means 50 shown here is just an example, and the wind intake means 50 may be of a shape other than a wind lens. For example, as shown in FIG. 4(a), a tube member 53 having a rectifying network 54 inside it may be used. The wind intake means 50 having this structure is attached so that the large diameter opening 55 faces outward and the small diameter opening 56 faces inward, as shown in FIG. 4(b).
　このような風取込み手段５０を設けることで、取り込まれた風を整流網５４で整流してブレード３１に直風を当てることができる。一般に、乱気流ではブレード３１がうまく回らないが、整流した直風を当てることでブレード３１をスムーズに回転させることができる。 By providing such a wind intake means 50, the introduced wind can be rectified by the rectifying net 54 and direct wind can be applied to the blades 31. Generally, the blades 31 do not rotate well in turbulence, but the blades 31 can be rotated smoothly by applying rectified direct wind.
　なお、風取込み手段５０を設置する向きは特に限定されないが、乱気流が発生した際の影響を小さく抑える観点から、各風取込み手段５０は、受風手段３０の回転方向と水平な方向に向けて設置するのが好ましい。 Note that the direction in which the wind intake means 50 is installed is not particularly limited, but from the viewpoint of minimizing the influence when turbulence occurs, each wind intake means 50 is installed in a direction parallel to the rotational direction of the wind blowing means 30. It is preferable to install
　ただし、風取込み手段５０は必須の構成ではなく、不要な場合には省略することもできる。たとえば、風取込み手段５０がなくても発電するのに十分な風力が見込める場所に設置する場合などには省略することができる。 However, the wind intake means 50 is not an essential configuration, and can be omitted if unnecessary. For example, the wind intake means 50 can be omitted if it is installed in a location where sufficient wind power can be expected to generate electricity even without the wind intake means 50.
　図５（ａ）（ｂ）に示すように、本発明の垂直型風力発電装置には、氷や雪の付着（以下「着氷等」という）を防止する付着防止手段６０を設けることもできる。一例として図５（ａ）（ｂ）に示す付着防止手段６０は、動力伝達軸２０に固定された取付けリング６１と、取付けリング６１から外向きに突設された打撃具６２と、外側構造体４０に設けられた被打撃具６３を備えている。 As shown in FIGS. 5(a) and 5(b), the vertical wind power generation device of the present invention may be provided with adhesion prevention means 60 for preventing the adhesion of ice and snow (hereinafter referred to as "icing etc."). . As an example, the adhesion prevention means 60 shown in FIGS. 5(a) and 5(b) includes an attachment ring 61 fixed to the power transmission shaft 20, a striking tool 62 protruding outward from the attachment ring 61, and an outer structure. A hit tool 63 provided at 40 is provided.
　図５（ａ）（ｂ）に示す取付けリング６１は円形状であり、その外周縁から外向きに打撃具６２が複数本突設されている。この実施形態の打撃具６２は、棒状部６２ａと棒状部６２ａの先端に設けられた球状の打撃球６２ｂを備えている。打撃具６２の設置間隔は等間隔でも不等間隔でもよく、その設置本数も垂直型風力発電装置の大きさ等に応じて決定することができる。 The mounting ring 61 shown in FIGS. 5(a) and 5(b) has a circular shape, and has a plurality of striking tools 62 protruding outward from its outer periphery. The hitting tool 62 of this embodiment includes a rod-like portion 62a and a spherical hitting ball 62b provided at the tip of the rod-like portion 62a. The striking tools 62 may be installed at equal or unequal intervals, and the number of hitting tools 62 may be determined depending on the size of the vertical wind power generator.
　この実施形態では、温度が上昇すると収縮し、温度が下がると膨張する材質で打撃具６２を構成するとともに、膨張時には打撃球６２ｂが被打撃具６３に接触し、収縮時には打撃球６２ｂが被打撃具６３に接触しないようにしてある。 In this embodiment, the hitting tool 62 is made of a material that contracts when the temperature rises and expands when the temperature drops, and when expanding, the hitting ball 62b comes into contact with the hit tool 63, and when contracting, the hitting ball 62b comes into contact with the hit tool 63. It is arranged so that it does not come into contact with the tool 63.
　このようにすることで、着氷等が生じやすい温度下では、打撃球６２ｂが被打撃具６３に接触して着氷等を防止することができ、着氷等が生じない温度下では、打撃球６２ｂが被打撃具６３に接触せず、打撃音による騒音の発生を防止することができる。 By doing so, the hitting ball 62b can contact the hit tool 63 to prevent icing, etc., at temperatures where icing etc. are likely to occur; The ball 62b does not come into contact with the hit tool 63, and it is possible to prevent the occurrence of noise due to the impact sound.
　被打撃具６３は、打撃球６２ｂによって打ち付けられる部材である。被打撃具６３は、ゴム材（ラバー材）等、打撃時に生じる振動を外側構造体４０に伝達できる各種の材質で構成することができる。被打撃具６３は外側構造体４０の内面に取り付けられている。被打撃具６３は外側構造体４０の周方向に間隔をあけて複数個設けられている。 The hit tool 63 is a member that is hit by the hitting ball 62b. The hit tool 63 can be made of various materials, such as a rubber material, that can transmit vibrations generated during hitting to the outer structure 40. The hit tool 63 is attached to the inner surface of the outer structure 40. A plurality of hit tools 63 are provided at intervals in the circumferential direction of the outer structure 40 .
　この実施形態では、取付けリング６１及び打撃具６２を、最下段の受風手段３０よりも低い位置に設置し、被打撃具６３を最下段の風取込み手段５０よりも低い位置に設置している。取付けリング６１、打撃具６２及び被打撃具６３は、これ以外の場所に設けることもできる。 In this embodiment, the attachment ring 61 and the striking tool 62 are installed at a lower position than the wind blowing means 30 at the lowest stage, and the hit tool 63 is installed at a position lower than the wind intake means 50 at the lowest stage. . The attachment ring 61, the striking tool 62, and the hit tool 63 can also be provided at other locations.
　前記付着防止手段６０の構成は一例であり、付着防止手段６０はこれ以外の構成とすることもできる。たとえば、取付けリング６１に図示しない電動ジャッキを接続し、当該電動ジャッキによって取付けリング６１及び打撃具６２を昇降させ、上昇時には被打撃具６３に当たり、降下時には被打撃具６３に当たらないようにすることができる。 The structure of the adhesion prevention means 60 is just an example, and the adhesion prevention means 60 can also have a structure other than this. For example, an electric jack (not shown) may be connected to the mounting ring 61, and the electric jack may be used to raise and lower the mounting ring 61 and the striking tool 62, so that they hit the struck tool 63 when rising and do not hit the struck tool 63 when descending. I can do it.
　この場合、電動ジャッキに図示しない電源装置（たとえば、サーモスタット付きの電源装置）を接続しておき、気温が予め設定した閾値（たとえば０℃）未満まで下がったきに電源がオンとなり、気温が閾値（たとえば０℃）以上まで上がったときに電源がオフとなるようにすることができる。 In this case, a power supply device (for example, a power supply device with a thermostat) (not shown) is connected to the electric jack, and the power is turned on when the temperature drops below a preset threshold (for example, 0 degrees Celsius). For example, the power can be turned off when the temperature rises above 0°C.
　このようにした場合、気温が閾値未満まで下がると電源が入ってジャッキが上がり、打撃具６２が被打撃具６３に接触し、気温が閾値以上まで上がると電源がオフになってジャッキが下がり、打撃具６２が被打撃具６３に接触しないようにすることができる。なお、この方式を採用する場合、電源装置は垂直型風力発電装置で生成された電気で動作するようにすることができる。 In this case, when the temperature drops below the threshold, the power is turned on and the jack is raised, and the striking tool 62 comes into contact with the hit tool 63, and when the temperature rises above the threshold, the power is turned off and the jack is lowered. It is possible to prevent the hitting tool 62 from coming into contact with the hit tool 63. Note that when this method is adopted, the power supply device can be operated with electricity generated by the vertical wind power generator.
　このような付着防止手段６０を設けることで、寒冷地でも着氷等による不具合が生じにくく、発電効率を維持しやすいというメリットがある。ただし、付着防止手段６０は必須の構成ではなく、不要な場合には省略することができる。 Providing such an adhesion prevention means 60 has the advantage that problems such as icing are less likely to occur even in cold regions, and power generation efficiency is easily maintained. However, the adhesion prevention means 60 is not an essential configuration and can be omitted if unnecessary.
　本発明の垂直型風力発電装置は、陸上に設置するほか、洋上に設置することもできる。設置は従来と同様の方法で行うことができ、軟弱な地盤に設置するような場合には、支柱の台座（先の例では三本の支柱を支える台座）に節付き基礎杭を用いることができる。 The vertical wind power generation device of the present invention can be installed not only on land but also on the ocean. Installation can be done in the same way as before, and when installing on soft ground, it is recommended to use knotted foundation piles for the pedestal of the pillar (in the previous example, the pedestal supporting three pillars). can.
　洋上に設置する場合、その設置方式は、設置場所の地盤までの距離等に応じて、たとえば、海底（地盤）に固定する着床方式と洋上に浮かせる浮体方式から選択することができる。 When installing on the ocean, the installation method can be selected from, for example, a landing method that is fixed to the seabed (ground) and a floating method that is floated on the ocean, depending on the distance to the ground at the installation location.
　以上の構成を備えた垂直型風力発電装置では、複数の受風手段３０が独立しているため、ある段の受風手段３０が故障した場合でも他の受風手段３０によって発電を継続することができ、発電停止のリスクを低減することができるメリットがある。 In the vertical wind power generation device having the above configuration, since the plurality of wind blowing means 30 are independent, even if one of the wind blowing means 30 at a certain stage fails, power generation can be continued using the other wind blowing means 30. This has the advantage of reducing the risk of power generation outage.
　また、各受風手段３０は単独のユニットとして取り扱うことができるため、故障時には故障した受風手段３０だけを交換し、健全な（故障していない）受風手段３０はそのまま使い続けられるため、メンテナンス性及び経済性に優れるというメリットがある。 In addition, since each wind blowing means 30 can be handled as an individual unit, in the event of a failure, only the broken wind blowing means 30 can be replaced, and healthy (non-faulty) wind blowing means 30 can continue to be used as is. It has the advantage of being excellent in maintainability and economy.
　なお、本発明の垂直型風力発電装置で生成された電気は通常の電力源として活用できることはもちろん、それ以外の使途に用いることもできる。たとえば、河川や海水を電気分解して水素を発生させることなどが考えられる。 Note that the electricity generated by the vertical wind power generation device of the present invention can not only be used as a normal power source, but also for other purposes. For example, it is possible to generate hydrogen by electrolyzing river or seawater.
　本発明の垂直型風力発電装置は小型化可能な構成であり、設置場所の自由度が高いため、インフラ条件の良い地域に設置し、近隣に水素製造施設を併設することで、グリーンエネルギーの集積環境を整えることができる。これにより、産業の振興に寄与しうると共に、地域おこしの一助ともなりうる。将来的には、地域パワーグリッドを確立し、施設や地域電力として活用することも期待できる。 The vertical wind power generation device of the present invention has a configuration that can be miniaturized and has a high degree of freedom in installation location, so it can be installed in an area with good infrastructure conditions and a hydrogen production facility nearby, allowing for the accumulation of green energy. You can adjust the environment. This will not only contribute to the promotion of industry, but also help revitalize the region. In the future, it is expected that a regional power grid will be established and used for facilities and regional power.
　また、本発明の垂直型風力発電装置は、プロペラ型の風力発電装置とは異なり、巨大なプロペラがむき出しで回転するようなものではないため、プロペラ型の風力発電装置に比べて設置場所の自由度が高い。たとえば、都心部で問題となっている高層ビルのビル風に対して防風の役割を果たすと同時に、設置地区の電力供給に寄与するものとしての活用が期待できる。 In addition, unlike propeller-type wind power generation devices, the vertical wind power generation device of the present invention does not have a huge propeller that rotates exposed, so it can be installed more freely than propeller-type wind power generation devices. High degree. For example, it can be expected to act as a windbreak against high-rise buildings, which is a problem in urban centers, and at the same time contribute to the power supply in the area where it is installed.
　（その他の実施形態）
－受風手段の変形例１－
　前記実施形態では、受風手段３０を構成するブレード３１の横方向の長さが段ごとに異なる場合を一例としているが、図８に示すように、ブレード３１はすべての段で同じ長さとすることもできる。 (Other embodiments)
-Variation example 1 of wind blowing means-
In the embodiment described above, the length of the blades 31 in the lateral direction that constitute the wind blowing means 30 is different for each stage, but as shown in FIG. 8, the length of the blades 31 is the same in all stages. You can also do that.
　場合によっては、最上段と二段目のブレード３１を同じ長さ、三段目と四段目のブレード３１を同じ長さというように、複数段のブレード３１を同じ長さとし、他の一段又は複数段のブレード３１をそれとは異なる長さとすることもできる。 In some cases, the blades 31 in multiple stages may be the same length, such as the blades 31 in the top and second stages are the same length, the blades 31 in the third and fourth stages are the same length, and the blades 31 in the other stages or The multiple stages of blades 31 can also have different lengths.
－受風手段の変形例２－
　前記実施形態では、受風手段３０として複数枚のブレード３１を用いる場合を一例としているが、受風手段３０はこれ以外の構造とすることもできる。たとえば、図９に示すような、アーム３１ｃの先端に略半球状（お椀状）の受風体３１ｄを備えた構造とすることができる。 -Variation example 2 of wind blowing means-
In the embodiment described above, a case where a plurality of blades 31 are used as the wind blowing means 30 is exemplified, but the wind blowing means 30 can also have a structure other than this. For example, as shown in FIG. 9, it is possible to have a structure in which an approximately hemispherical (bowl-shaped) wind receiving body 31d is provided at the tip of an arm 31c.
　図９に示す例では、アーム３１ｃとして、凹部（アーム凹部）３１ｅを備えた半割パイプ状の部材を用いている。アーム凹部３１ｅを備えたアーム３１ｃを用いることで受風面積が大きくなり、風を受けやすくなるというメリットがある。 In the example shown in FIG. 9, a half-pipe-shaped member with a recess (arm recess) 31e is used as the arm 31c. By using the arm 31c provided with the arm recess 31e, there is an advantage that the wind receiving area becomes large and the wind is easily received.
　アーム３１ｃとして半割パイプ状の部材を用いる場合、アーム凹部３１ｄの開口周縁（アーム開口周縁）３１ｆは、アーム凹部３１ｅ内に風が入り込みやすいように、内向きに窄まるようにしてある。窄ませる程度は適宜設計することができる。アーム３１ｃは、半割パイプ状の部材のほか、真円パイプや無垢の軸材などで構成することもできる。 When a half-pipe-shaped member is used as the arm 31c, the opening periphery 31f of the arm recess 31d (arm opening periphery) is tapered inward so that wind can easily enter the arm recess 31e. The degree of narrowing can be designed as appropriate. The arm 31c can be made of a perfectly round pipe, a solid shaft material, or the like, in addition to a half-pipe member.
　図９に示す受風体３１ｄは、アーム凹部３１ｅ側の面に凹部（受風体凹部）３１ｇを備えた略半球状（お椀状）の中空部材である。受風体３１ｄの開口周縁（受風体開口周縁）３１ｈは、受風体３１ｄ内に風が入り込みやすいように、内向きに窄まるようにしてある。窄ませる程度は適宜設計することができる。受風体３１ｄの構造は半球状以外であってもよい。 The wind blower 31d shown in FIG. 9 is a substantially hemispherical (bowl-shaped) hollow member that has a recess (wind blower recess) 31g on the arm recess 31e side. The opening periphery 31h of the wind receiving body 31d (wind receiving body opening periphery) is configured to narrow inward so that the wind can easily enter into the wind receiving body 31d. The degree of narrowing can be designed as appropriate. The structure of the wind receiving body 31d may be other than hemispherical.
　なお、説明の便宜上、図９では一段分の受風手段３０のみを示しているが、受風手段３０を、アーム３１ｃの先端に受風体３１ｄを備えたもので構成する場合も、受風手段３０は複数段設けることができる。 For convenience of explanation, only one stage of the wind blowing means 30 is shown in FIG. 30 can be provided in multiple stages.
－受風手段の変形例３－
　受風手段３０には、図１０に示すような円板状や方形状の回転盤３１ｉの上面に、受風面を有する一又は二以上（図示する例では複数）の受風体３１ｊを備えたものを用いることもできる。回転盤３１ｉには、円形状や方形状の板材のほか、楕円形状等の任意形状の板材を用いることもできる。場合によっては、一部が湾曲した板材や一部が切り欠かれた板材等を回転盤３１ｉとして用いることもできる。また、回転盤３１ｉは板材でなくても良い。 -Variation example 3 of wind blowing means-
The wind receiving means 30 includes one or more (in the illustrated example, a plurality of) wind receiving bodies 31j each having a wind receiving surface on the upper surface of a disc-shaped or rectangular rotary disk 31i as shown in FIG. You can also use something. In addition to a circular or rectangular plate material, a plate material having an arbitrary shape such as an elliptical shape can also be used for the rotary disk 31i. In some cases, a partially curved plate material, a partially cut-out plate material, or the like may be used as the rotary disk 31i. Further, the rotary disk 31i does not have to be a plate material.
　図１０に示す受風体３１ｊは、凹部（受風体凹部）３１ｋを備えた略半球状（お椀状）の部材を半分にした形状の部材である。受風体３１ｊの形状はこれ以外でもよく、図９の受風体３１ｄと同様の略半球状（お椀状）等とすることもできる。 The wind blower 31j shown in FIG. 10 is a half-shaped member that is substantially hemispherical (bowl-shaped) and includes a concave portion (blow body concavity) 31k. The shape of the wind blower 31j may be other than this, and may be approximately hemispherical (bowl-shaped) similar to the wind blower 31d in FIG. 9.
　受風体３１ｊの開口周縁（受風体開口周縁）３１ｍは、受風体３１ｊ内に風が入り込みやすいように、内向きに窄まるようにするのが望ましい。窄ませる程度は適宜設計することができる。受風体３１ｊには、湾曲面を有する曲面板や湾曲を有しない平坦な平板（図１１参照）等を用いることもできる。 It is desirable that the opening periphery (periphery of the wind receiving body opening) 31m of the wind receiving body 31j narrows inward so that the wind can easily enter the wind receiving body 31j. The degree of narrowing can be designed as appropriate. A curved plate with a curved surface, a flat plate without a curve (see FIG. 11), etc. can also be used as the wind receiving body 31j.
　このような構造の受風体３１ｊを有する受風手段３０を用いる場合も、受風体３１ｊ同士で回転力の打ち消し合いが起こりにくいように、各受風手段３０は非点対称な構造とするのが好ましい。 Even when using the wind-blowing means 30 having the wind-blowing bodies 31j having such a structure, it is preferable that each wind-blowing means 30 has an asymmetrical structure so that the rotational forces of the wind-blowing bodies 31j are unlikely to cancel each other out. preferable.
　図１１に示すように、受風体３１ｊは、風を受ける向きによって起立した状態（以下「起立状態」という）と倒伏した状態（以下「倒伏状態」という）の間で姿勢が変化するような可動式の構造とすることもできる。 As shown in FIG. 11, the wind receiving body 31j is movable so that its posture changes between an upright state (hereinafter referred to as "upright state") and a laid down state (hereinafter referred to as "lowered state") depending on the direction in which it receives the wind. It can also have the structure of Eq.
　具体的には、受風体３１ｊの一方の面（以下「第一面」という）側で風を受けた場合に受風体３１ｊが起立し、他方の面（以下「第二面側」という）で風を受けた場合に受風体３１ｊが倒伏するようにすることができる。 Specifically, when the wind receiving body 31j receives wind on one surface (hereinafter referred to as "first surface") side, the wind receiving body 31j stands up, and on the other surface (hereinafter referred to as "second surface side"). The wind receiving body 31j can be made to lie down when exposed to wind.
　また、受風体３１ｊは回転盤３１ｉの上面に設ける場合を一例としているが、受風体３１ｊは回転盤３１ｉの下面に設けることもできる。場合によっては、図１２（ａ）（ｂ）のように、回転盤３１ｉの上下両面に設けることもできる。上下両面に設ける場合、上下で同じ位置に設けることも、上下でずらして設けることもできる。 Furthermore, although the wind receiving body 31j is provided on the upper surface of the rotating disk 31i as an example, the wind receiving object 31j may also be provided on the lower surface of the rotating disk 31i. Depending on the case, they may be provided on both the upper and lower surfaces of the rotary disk 31i, as shown in FIGS. 12(a) and 12(b). When provided on both the upper and lower surfaces, it can be provided at the same position on the upper and lower sides, or it can be provided at different positions on the upper and lower sides.
　この受風手段３０を複数段設ける場合、図１３（ａ）のように回転盤３１ｉの直径（面積）が同じものを用いることも、図１３（ｂ）のように直径（面積）が異なるものを用いることもできる。受風体３１ｊを回転盤３１ｉの上下両面に設ける場合も同様である。 When providing multiple stages of the wind blowing means 30, rotating disks 31i having the same diameter (area) as shown in FIG. 13(a) may be used, or rotating disks 31i having different diameters (areas) as shown in FIG. 13(b) may be used. You can also use The same applies to the case where the wind receiving bodies 31j are provided on both the upper and lower surfaces of the rotary disk 31i.
　面積の異なるものを用いる場合、図１３（ｂ）のように上段側から下段側に向かうに従って、面積の広いものとなるようにするほか、下段側から上段側に向かうに従って、面積の広いものとなるようにすることもできる。 When using items with different areas, the area should be larger from the upper side to the lower side as shown in Figure 13(b), and the area should be wider from the lower side to the upper side. You can also make it so.
　受風手段３０として、回転盤３１ｉに複数の受風体３１ｊを備えたものを用いる場合、回転盤３１ｉは動力伝達軸２０に固定される。受風手段３０は、たとえば、図１４に示すように、内支柱２２の外側に筒状の動力伝達軸２０をベアリング２３を介して配置し、その動力伝達軸２０に回転盤３１ｉを固定することができる。 When using a rotary disk 31i equipped with a plurality of wind blowing bodies 31j as the wind blowing means 30, the rotary disk 31i is fixed to the power transmission shaft 20. The wind blowing means 30 includes, for example, as shown in FIG. 14, a cylindrical power transmission shaft 20 is disposed outside the inner support 22 via a bearing 23, and a rotary disk 31i is fixed to the power transmission shaft 20. I can do it.
　この場合、回転盤３１ｉによる回転力が動力伝達軸２０を介して発電機１０に伝達され、発電が行われる。受風手段３０の動力伝達軸２０への固定方法はこれ以外でもよく、たとえば、回転盤３１ｉを図７に示すような構成で動力伝達軸２０に固定し、回転盤３１ｉが回転したときに動力伝達軸２０が回転するようにすることもできる。 In this case, the rotational force by the rotary disk 31i is transmitted to the generator 10 via the power transmission shaft 20, and power generation is performed. The method of fixing the wind blowing means 30 to the power transmission shaft 20 may be other than this. For example, the rotating disk 31i may be fixed to the power transmitting shaft 20 with the configuration shown in FIG. It is also possible to make the transmission shaft 20 rotate.
　受風手段の変形例３で説明した受風手段３０の回転盤３１ｉは、その形状によっては、整流体３２のような風の流れを整える機能を果たしうるものである。 Depending on its shape, the rotary disk 31i of the wind blowing means 30 described in the third modification of the wind blowing means can perform the function of adjusting the flow of wind like the flow regulator 32.
－整流体の変形例－
　前記実施形態では、整流体３２として円板状や方形状、楕円形状、その他各種形状の板材等を用いる場合を一例としているが、整流体３２はこれ以外の構造とすることもできる。たとえば、受風手段の変形例３で説明した受風手段３０、具体的には、円形状や方形状の回転盤３１ｉの上面と下面の双方又はいずれか一方に、一又は二以上の受風体３１ｊを備えたものを、整流体３２として用いることができる。この場合の整流体３２の具体的な構成は、受風手段の変形例３の受風手段３０と同様であるため、ここではその説明は省略する。 - Variation of fluid regulation -
In the embodiment described above, as an example, the flow regulator 32 is a disk-shaped, square-shaped, elliptical, or other various shaped plate material, but the flow regulator 32 can also have a structure other than this. For example, the wind blowing means 30 described in Modification 3 of the wind blowing means, specifically, one or more wind blowing bodies may be installed on both or either of the upper surface and the lower surface of the circular or rectangular rotary plate 31i. 31j can be used as the flow regulator 32. The specific configuration of the flow regulator 32 in this case is the same as that of the wind blowing means 30 of Modification 3 of the wind blowing means, so the description thereof will be omitted here.
－その他の構成の変形例－
　前記実施形態では、取付けリング６１、打撃具６２及び被打撃具６３を一段設ける場合を一例としているが、取付けリング６１、打撃具６２及び被打撃具６３は、上下方向に間隔をあけて複数段設けることもできる。 -Other configuration variations-
In the embodiment described above, the mounting ring 61, the striking tool 62, and the hit tool 63 are provided in one stage as an example, but the mounting ring 61, the hitting tool 62, and the hit tool 63 are arranged in multiple stages at intervals in the vertical direction. It is also possible to provide one.
　前記実施形態では、動力伝達軸２０の下端に発電機１０が設けられた場合を一例としているが、発電機１０はこれ以外の場所に設けることもできる。たとえば、図６（ａ）に示すように動力伝達軸２０の上端に設けることもできる。この場合、動力伝達軸２０の下端側は軸受けで支持すればよい。 In the embodiment described above, the case where the generator 10 is provided at the lower end of the power transmission shaft 20 is taken as an example, but the generator 10 can also be provided at a location other than this. For example, it can also be provided at the upper end of the power transmission shaft 20 as shown in FIG. 6(a). In this case, the lower end side of the power transmission shaft 20 may be supported by a bearing.
　前記実施形態では、発電機１０が一つの場合を一例としているが、発電機１０は二以上設けることもできる。この場合、たとえば、図６（ｂ）のように動力伝達軸２０の上端側と下端側に一つずつ設けたり、図６（ｃ）のように動力伝達軸２０の軸方向に間隔をあけて設けたりすることができる。発電機１０を二以上設ける場合、受風手段３０毎に設けることもできる。 In the embodiment, the case where there is one generator 10 is taken as an example, but two or more generators 10 can also be provided. In this case, for example, one may be provided at the upper and lower ends of the power transmission shaft 20 as shown in FIG. 6(b), or one may be provided at intervals in the axial direction of the power transmission shaft 20 as shown in FIG. 6(c). It can be set up. When two or more generators 10 are provided, one can be provided for each wind blowing means 30.
　発電機１０を二以上設ける場合、図７に示すように、芯材となる支柱（以下「内支柱」という）２２を立設するとともに、その内支柱２２の外側に、複数枚のブレード３１を備えた筒状の動力伝達軸２０をベアリング２３を介して配置し、各動力伝達軸２０が個別に回転するようにすることができる。 When two or more generators 10 are provided, as shown in FIG. The provided cylindrical power transmission shafts 20 can be disposed via bearings 23 so that each power transmission shaft 20 can be rotated individually.
　内支柱２２は上端の軸受２１（図６（ｃ））と最下段の発電機１０の間に、回転しないように固定してある。各動力伝達軸２０は一つの発電機１０につき一つずつ設けられ、各発電機１０に一本ずつ動力伝達軸２０が接続されている。各動力伝達軸２０が回転すると、当該動力伝達軸２０が接続された発電機１０によって発電される。 The inner support 22 is fixed between the bearing 21 at the upper end (FIG. 6(c)) and the generator 10 at the lowermost stage so as not to rotate. One power transmission shaft 20 is provided for each generator 10, and one power transmission shaft 20 is connected to each generator 10. When each power transmission shaft 20 rotates, power is generated by the generator 10 to which the power transmission shaft 20 is connected.
　このようにした場合、発電機１０及び動力伝達軸２０並びに当該動力伝達軸２０に設けられた受風手段３０が一つの発電ユニット２４として機能する。これにより、一つの発電ユニット２４が故障した場合でも、他の発電ユニット２４によって発電を継続することができ、発電停止のリスクを低減することができる。 In this case, the generator 10, the power transmission shaft 20, and the wind blowing means 30 provided on the power transmission shaft 20 function as one power generation unit 24. Thereby, even if one power generation unit 24 fails, power generation can be continued by the other power generation units 24, and the risk of power generation stoppage can be reduced.
　なお、発電機１０が一つの場合、動力伝達軸２０は中実の柱材を用いればよいが、発電機１０を二以上設ける場合と同様、内支柱２２の外側にベアリング２３を介して配置する筒状のものを用いることもできる。 In addition, when there is one generator 10, a solid pillar material may be used as the power transmission shaft 20, but as in the case where two or more generators 10 are provided, it is arranged on the outside of the inner pillar 22 via a bearing 23. A cylindrical one can also be used.
　前記実施形態では説明を省略しているが、動力伝達軸２０には、回転力を増幅して発電機１０に伝える増速機や、強風の際にブレード３１や動力伝達軸２０の回転速度を抑えるブレーキ装置等を設けることもできる。 Although the description is omitted in the embodiment, the power transmission shaft 20 includes a speed increaser that amplifies the rotational force and transmits it to the generator 10, and a speed increaser that increases the rotational speed of the blades 31 and the power transmission shaft 20 during strong winds. It is also possible to provide a brake device or the like to suppress the damage.
　前記実施形態では、打撃具６２を温度が上昇すると収縮し、温度が下がると膨張する材質で構成する場合を一例としているが、被打撃具６３を同材料で構成することもできる。場合によっては、双方を同材料で構成することもできる。 In the embodiment described above, the striking tool 62 is made of a material that contracts when the temperature rises and expands when the temperature falls, but the struck tool 63 can also be made of the same material. In some cases, both may be made of the same material.
　前記実施形態では、取付けリング６１を電動ジャッキで昇降させる場合を一例としているが、被打撃具６３を昇降させるようにすることもできる。たとえば、被打撃具６３を内向きに突設させたリング状のベース座を外側構造体４０の内面に設置し、そのベース座を電動ジャッキで昇降させるようにすることで、取付けリング６１を電動ジャッキで昇降させる場合と同様の作用効果を得られる。 In the embodiment described above, the mounting ring 61 is raised and lowered using an electric jack, but the hit tool 63 can also be raised and lowered. For example, by installing a ring-shaped base seat on which the hit tool 63 projects inward on the inner surface of the outer structure 40 and raising and lowering the base seat with an electric jack, the mounting ring 61 can be moved electrically. You can obtain the same effect as when lifting and lowering with a jack.
　前記実施形態の構成は一例であり、本発明の垂直型風力発電装置の構成は前記構成に限定されるものではない。本発明の垂直型風力発電装置の構成は、所期の目的を達成できる範囲で、適宜追加、入れ替え、削除等の変更を加えることができる。 The configuration of the embodiment described above is an example, and the configuration of the vertical wind power generator of the present invention is not limited to the configuration described above. The configuration of the vertical wind power generation device of the present invention can be appropriately modified such as additions, replacements, deletions, etc. within a range that can achieve the intended purpose.
　本発明の垂直型風力発電装置は、陸上に設置する陸上風力発電装置としてのみならず、洋上に設置する洋上風力発電装置としても利用することができる。 The vertical wind power generation device of the present invention can be used not only as an onshore wind power generation device installed on land, but also as an offshore wind power generation device installed on the ocean.
