Description

【０００１】
【発明の属する技術分野】
本発明は、発電所内部に設置された水力発電機を冷却する冷却風を利用した風力発電装置に関する。
【０００２】
【従来の技術】
近年、クリーンエネルギーである風力を利用した発電が広く利用され始めている。通常は風の強い屋外にタワーを建設して先端に風車を装着するタイプが多い。他の形態としてビル風を利用すべくビルの側壁面頂部にシロッコファン型の風車を配置し、この風車を発電機の回転軸に連結する風力発電装置が知られている(特許文献１を参照)。また、住宅の屋根に風力発電機を設置した例も知られている(特許文献２)。
【０００３】
一方、図２に示すように水力発電所１１は一般に開放通風形と称し、所外から空気を吸い込みこの空気で水力発電機１２を冷却している。すなわち、水力発電所１１の側壁１３にはフィルタ１４が装着された吸気口１５が設けられており、他の側壁１６には排気ダクト１７の一端が開口する排気口１８が設けられている。排気ダクト１７の他端は水力発電機１２に接続されている。水力発電機１２の内部には回転軸１９に接続されている図示しない回転子に冷却ファンが取着されている。
【０００４】
水力発電機１２が駆動状態にあるときには、冷却ファンによって発電機内部へ冷却用空気を強制的に取り込み冷却後の排気は排気ダクト１７を介して排気口から所外へ出される。冷却用空気は、冷却ファンの吸引により吸気口１５から所内へ吸引され水力発電機１２内へ誘導される。吸気口１５に設けたフィルタ１４によって異物が除去され水力発電機１２内へは清浄な空気が誘導される。吸気口１５から排気口１８までの空気は図に矢印で示したように流れるものである。

【０００７】
【発明が解決しようとする課題】
図２に示すように、水力発電機１２を格納した開放通風形の水力発電所１１では、吸気口１５における吸気の流れは非常に速く、近くに物を置いておくと吹き飛ばされる程度である。また、吸気口を閉じてしまうと所内が負圧となってしまい、入口の扉が開かなくなったり、ゴミが吸い込まれるなどの不具合がある。天井などに吸気口を設置している発電所もあり、多くの発電所で対応に苦慮しているのが現状である。また、ビル風や住宅の屋根に風力発電機を設置するなどの例は多数知られているが、水力発電所においては発電機冷却にのみ吸気が利用されている。
【０００８】
本発明は、上述した課題を解決するためになされたもので、簡単な構成で課題の解決のみならずクリーンエネルギの利用をも図ることが可能な水力発電機冷却風利用による風力発電装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
本発明の請求項１に係わる水力発電機冷却風利用による風力発電装置は、水力発電機が格納された開放通風形水力発電所と、この水力発電所の側壁面に設けられた吸気口並びに排気口と、この吸気口並びに排気口の少なくとも吸気口に装着された風力発電機とを具備することを要旨とする。
【００１０】
本発明の請求項２に係わる水力発電機冷却風利用による風力発電装置は、前記吸気口にはフィルタが設けられていることを要旨とする。
【００１１】
本発明の請求項３に係わる水力発電機冷却風利用による風力発電装置は、前記風力発電機と前記側壁とは通気を阻害しない支持部材にて固定されていることを要旨とする。
【００１２】
【発明の実施の形態】
以下に本発明に係わる実施形態を図１を参照して説明する。なお、図２と同一の箇所は同一符号にて示し重複した説明は省力する。開放通風形の水力発電所１１の吸気口１５に第1風力発電機２０を装着する。第1風力発電機２０は吸気口１５に支持部材２１によって固定され、この支持部材２１は固定機能を有するとともに吸気を阻害しないように例えばメッシュ状部材や通気孔を有する部材にて構成されている。また、この第1風力発電機２０はフィルタ１４の内側に配置され、フィルタ１４によって吸気口１５から水力発電所11内へ異物の侵入を排除する。第1風力発電機２０を設置したことにより、吸気口１５から社内へ吸引される風を利用して発電がなされる。
【００１３】
また、水力発電機１２を冷却した風は排気口１８から排出されるが、この排気口１８にも第2風力発電機２２が設置されている。第2風力発電機２２は排気口１８に支持部材２３によって固定され、この支持部材２３は吸気口１５の支持部材２１と同様に固定機能とともに排気を阻害しないように構成されている。このようにして、水力発電機１２を冷却した排気が排気ダクト１７を介して第2風力発電機２２に作用し、発電がなされる。
【００１４】
なお、上述した実施形態では風力発電機を吸気口１５並びに排気口１８のいずれにも装着したが、いずれか一方にのみ風力発電機を設置するようにしてもよく、この場合には少なくとも吸気口１５に設置することが望ましい。また、風力発電機によって発電された電力は水力発電所内の電源として使用される。
【００１５】
【発明の効果】
本発明に係わる風力発電装置によって、近くの物を吹き飛ばす程度の強風を発電に利用できるとともに、社内導入される冷却風が異常な強風になることを防止することができるようになった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wind power generator using cooling air for cooling a hydroelectric generator installed inside a power plant.
[0002]
[Prior art]
In recent years, power generation using wind power, which is clean energy, has begun to be widely used. Usually, there are many types where a tower is constructed outside the windy area and a windmill is attached to the tip. As another form, there is known a wind power generation device in which a sirocco fan-type wind turbine is arranged at the top of a side wall surface of a building in order to utilize building wind, and the wind turbine is connected to a rotating shaft of a generator (see Patent Document 1). ). An example in which a wind power generator is installed on a roof of a house is also known (Patent Document 2).
[0003]
On the other hand, as shown in FIG. 2, the hydroelectric power plant 11 is generally referred to as an open ventilation type, and air is sucked from outside and cooled by the air. That is, the inlet 13 to which the filter 14 is attached is provided on the side wall 13 of the hydroelectric power plant 11, and the other side wall 16 is provided with an outlet 18 at which one end of the exhaust duct 17 opens. The other end of the exhaust duct 17 is connected to the hydraulic power generator 12. A cooling fan is attached to the rotor (not shown) connected to the rotating shaft 19 inside the hydroelectric generator 12.
[0004]
When the hydraulic power generator 12 is in a driving state, cooling air is forcibly taken into the power generator by the cooling fan, and the exhaust after cooling is discharged from the exhaust port through the exhaust duct 17 to the outside. The cooling air is drawn into the place from the intake port 15 by suction of the cooling fan, and is guided into the hydraulic power generator 12. Foreign matter is removed by the filter 14 provided in the intake port 15, and clean air is guided into the hydraulic power generator 12. The air from the intake port 15 to the exhaust port 18 flows as indicated by arrows in the figure.

[Problems to be solved by the invention]
As shown in FIG. 2, in the open-ventilated hydroelectric power plant 11 in which the hydroelectric generator 12 is housed, the flow of the intake air at the intake port 15 is very fast, and the air is blown off when an object is placed nearby. In addition, if the intake port is closed, the inside of the facility will be at a negative pressure, and the entrance door will not open or dust will be sucked in. Some power plants have air inlets on ceilings and other facilities, and many power plants are currently struggling to respond. There are many known examples of building wind or installing a wind power generator on the roof of a house. In a hydroelectric power plant, intake air is used only for cooling the generator.
[0008]
The present invention has been made to solve the above-described problem, and provides a wind power generation device using a cooling wind of a hydroelectric generator, which can achieve not only the problem but also the use of clean energy with a simple configuration. The purpose is to do.
[0009]
[Means for Solving the Problems]
A wind power generator utilizing a cooling wind utilizing a hydroelectric generator according to claim 1 of the present invention comprises an open ventilation type hydroelectric power plant in which a hydroelectric generator is stored, an intake port provided on a side wall surface of the hydroelectric power plant, and an exhaust gas. The gist of the present invention is to have a mouth, and a wind power generator attached to at least the inlet of the inlet and the outlet.
[0010]
According to a second aspect of the present invention, there is provided a wind turbine generator utilizing cooling air from a hydroelectric generator, wherein a filter is provided at the intake port.
[0011]
According to a third aspect of the present invention, there is provided a wind turbine generator utilizing cooling air from a hydroelectric generator, wherein the wind turbine and the side wall are fixed by a support member which does not hinder ventilation.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment according to the present invention will be described below with reference to FIG. Note that the same parts as those in FIG. The first wind power generator 20 is mounted on the intake port 15 of the open-ventilated hydroelectric power plant 11. The first wind power generator 20 is fixed to the intake port 15 by a support member 21. The support member 21 has a fixing function and is made of, for example, a mesh-shaped member or a member having a vent so as not to disturb the intake. . In addition, the first wind power generator 20 is disposed inside the filter 14, and the filter 14 prevents foreign matter from entering the hydroelectric power plant 11 from the intake port 15. By installing the first wind power generator 20, power is generated by utilizing the wind sucked from the air inlet 15 into the office.
[0013]
The wind that has cooled the hydroelectric generator 12 is discharged from the exhaust port 18, and a second wind power generator 22 is also installed at the exhaust port 18. The second wind power generator 22 is fixed to the exhaust port 18 by a support member 23, and the support member 23 is configured to have a fixing function and not obstruct the exhaust similarly to the support member 21 of the intake port 15. In this manner, the exhaust gas that has cooled the hydraulic power generator 12 acts on the second wind power generator 22 via the exhaust duct 17 to generate power.
[0014]
In the above-described embodiment, the wind power generator is mounted on both the intake port 15 and the exhaust port 18. However, the wind power generator may be installed on only one of the wind power generators. 15 is desirable. Further, the power generated by the wind power generator is used as a power source in the hydroelectric power plant.
[0015]
【The invention's effect】
With the wind power generator according to the present invention, a strong wind that blows nearby objects can be used for power generation, and it is possible to prevent the cooling wind introduced in the company from becoming an abnormally strong wind.
