Abstract

PROBLEM TO BE SOLVED: To provide a wind power generator in which there is provided a wall for concentrating wind power on the peripheries of a plurality of wind power generation turbines in order to solve such a problem that the amount of the electric power generated by a conventional wind power generator is unstable or in order to reduce the damage caused by a lightning strike or strong wind.SOLUTION: A part of the side face of a columnar framework (1) is set as a wind receiving plate (2), and a plurality of vent holes (3) are arranged in the center of the wind receiving plate (2). In the respective vent holes (3), the wind power generation turbines (4) and sliding doors (5) for shutting off a wind through the vent hole (3) are arranged respectively. In the wind power generator, a bearing or the like is arranged on a bottom surface portion of the columnar framework (1) and the column is turned to correspond to wind directions.

Description

この発明は、円柱状の骨組みの側面の一部を壁にし、そこに複数の通風孔、それを閉じる扉及びタービン発電機を設置した、風力発電機に関するものである。  The present invention relates to a wind power generator in which a part of a side surface of a cylindrical frame is used as a wall, and a plurality of ventilation holes, a door for closing the ventilation holes, and a turbine generator are installed therein.

従来の風力発電機は、水平回転軸のプロペラ型がよく見られる。また風向を選ばない垂直回転軸のダリウス型もある。いずれの方式も、空中で羽根が回る構造で、より多くの風力を得るため巨大化している。  Conventional wind power generators often have a propeller type with a horizontal rotating shaft. There is also a Darius type with a vertical rotation axis that does not choose the wind direction. Both systems have a structure in which the blades rotate in the air, and are enlarged to obtain more wind power.

これは次のような欠点があった。
（イ） 通常、風速３ｍ〜２０ｍの運転で、最適な回転を得るため羽根の角度を調整する複雑で高価な仕組みが必要である。それでも出力が不安定であり、強風下では減速または停止させるなど無駄も多い。
（ロ） プロペラが空中で回る構造による課題として、野鳥がぶつかる事故や、落雷による破損、強風による破損、風切り音による騒音がある。
（ハ） 発電量を多く求めると、羽根が長大化し、それにともない強固な支柱と基礎が必要になる。又、一基あたり規模が大きくなると、停止した時の失う電力の影響も大きい。
本発明は、以上のような欠点をなくすためなされたものである。This has the following drawbacks.
(B) Normally, a complicated and expensive mechanism for adjusting the blade angle is required to obtain optimum rotation in operation at a wind speed of 3 m to 20 m. Nevertheless, the output is unstable, and there is a lot of waste such as slowing down or stopping in strong winds.
(B) Problems caused by the structure in which the propeller rotates in the air include accidents involving wild birds, damage from lightning, damage from strong winds, and noise from wind noise.
(C) When a large amount of electricity is generated, the blades become longer, and accordingly, a strong support and foundation are required. In addition, as the scale per unit increases, the effect of the power lost when stopped is also great.
The present invention has been made to eliminate the above drawbacks.

これらの課題を解決するための構造を考えてみた。（図１参照）円柱状の骨組み（１）の側面の一部に風受け板（２）を取り付け、（２）の中央に通風孔（３）を複数設ける。各通風孔（３）には風力発電タービン（４）とスライド扉（５）がそれぞれ付いており、スライド扉（５）を閉じることで通風孔（３）は個別に通風を遮断できるものである。骨組み（１）の底面円周と地面の間はベアリング（６）で、風受け板（２）がより風力を受けるよう円柱を回して調整する。（図２参照）
本発明はこのような構造である。I considered a structure to solve these problems. (See FIG. 1) A wind receiving plate (2) is attached to a part of the side surface of the columnar framework (1), and a plurality of ventilation holes (3) are provided in the center of (2). Each ventilation hole (3) has a wind power generation turbine (4) and a slide door (5), respectively. By closing the slide door (5), the ventilation hole (3) can individually block ventilation. . Between the bottom circumference of the framework (1) and the ground, a bearing (6) is used to adjust the wind receiving plate (2) by rotating the cylinder so that it receives more wind force. (See Figure 2)
The present invention has such a structure.

（イ）風受け板（２）で風力を集約させ利用するため、タービンのサイズ以上に多くの風力が利用でき効率的である。
（ロ）微風下では、個別に開閉できるスライド扉（５）を用いて運転台数を制限し、効率よく発電できる回転数を維持できる。これにより羽の角度を調整する機能やプロペラを止めるブレーキが不要になり、機械的に簡素化できる。故障が発生すれば、そこだけ扉を閉じて修理すればいいので、全体としては発電を継続できる。
（ハ）骨組み（１）の上に避雷針を設置することで落雷被害を軽減できる。
（ニ）強風下の対処については（図３参照）風受け板（２）に風を横から受ける向きに調整することで、ベンチュリー効果により風受け板（２）に揚力が発生するので、風力発電タービン（４）の破損を回避しつつ、発電も行うことができる。
（ホ）骨組み（１）は円柱状であるため、従来の一本柱の支柱に比べ華奢な材料でも十分強度を備える。また底面も広く安定するので、基礎杭など深く打ち込む必要がない。(B) Since wind power is concentrated and used by the wind receiving plate (2), more wind power than the size of the turbine can be used and is efficient.
(B) Under a slight breeze, the number of operating units can be limited using the slide doors (5) that can be opened and closed individually, and the number of rotations that can generate power efficiently can be maintained. This eliminates the need for a function for adjusting the wing angle and a brake for stopping the propeller, which can be simplified mechanically. If a failure occurs, it is enough to close the door and repair it, so power generation can continue as a whole.
(C) Lightning damage can be reduced by installing a lightning rod on the framework (1).
(D) Regarding countermeasures under strong winds (see Fig. 3), the wind receiving plate (2) is adjusted to receive the wind from the side so that lift is generated in the wind receiving plate (2) by the venturi effect. Power generation can also be performed while avoiding damage to the power generation turbine (4).
(E) Since the framework (1) is cylindrical, even a delicate material is sufficiently strong as compared with a conventional single pillar support. In addition, the bottom is stable and wide, so there is no need to dig deep into foundation piles.

（イ） 円柱状の骨組み（１）は、軽量鉄骨等のトラス構造で、又風受け板（２）は金属板、木板、プラスチック板、布など軽量かつ安価で耐候性に優れる素材を用いると良い。
（ロ） 円柱の天井部分に太陽光発電パネルを設置できる。これによりハイブリッド発電になり電力供給が安定する。このパネルは風受け板（２）で受けた風が上方に抜けるのを防止し、風力発電にも有効である。
（ハ） 円柱の内部の利用法としては、（図４参照）余った電力で錘（９）を引き上げ、電力が足りない時は、錘（９）の落下により発電する蓄電池とするのがよい。洋上であるならば（図５参照）円柱内部に水槽（１０）を設け揚水発電をしてもいい。いずれも骨組み（１）に荷重を懸け低重心化する。また、発電量が平準化できると売電に有利である。(B) The cylindrical frame (1) is a truss structure such as a lightweight steel frame, and the wind-receiving plate (2) is a lightweight, inexpensive and weatherproof material such as a metal plate, wood plate, plastic plate or cloth. good.
(B) A photovoltaic panel can be installed on the ceiling of the cylinder. As a result, hybrid power generation is achieved and power supply is stabilized. This panel prevents the wind received by the wind receiving plate (2) from coming out upward, and is also effective for wind power generation.
(C) As a method of using the inside of the cylinder (see FIG. 4), it is recommended that the weight (9) be pulled up with surplus power, and when the power is insufficient, a storage battery that generates power by dropping the weight (9) is good. . If it is offshore (refer FIG. 5), you may provide a water tank (10) inside a cylinder and perform pumped-storage power generation. In both cases, the load is applied to the framework (1) to lower the center of gravity. In addition, if the power generation amount can be leveled, it is advantageous for power sales.
