トンネル内を走行する列車により発生する列車風は、新幹線車両の通過時には最大で２０ｍ／ｓとなり、非常に大きなエネルギーを持つ場合がある。東日本大震災以降の日本の電力事情を鑑みると、このような大きなエネルギーを再利用し、電力不足を少しでも補うような技術開発が工学の分野だけでなく日本社会全般で必要とされている。また、トンネルの維持管理の分野でも、トンネル変状を精緻にモニタリングする計測技術が実用化段階に進みつつあり、トンネルの安全を確かなものにするためには、計測の精度も必然的に高める必要がある。高度な計測には大きな電力量が必要であるため、計測機の電力をトンネル内で確実に、継続的に得られる技術開発が必須である。   The train wind generated by the train traveling in the tunnel is 20 m / s at the maximum when the Shinkansen vehicle passes and may have very large energy. Considering the power situation in Japan after the Great East Japan Earthquake, it is necessary not only in the field of engineering but also in Japanese society as a whole to develop technology that reuses such a large amount of energy and compensates for a shortage of power. Also, in the field of tunnel maintenance, measurement technology for precise monitoring of tunnel deformation is being put into practical use, and in order to ensure the safety of the tunnel, the accuracy of measurement is inevitably increased. There is a need. Advanced measurement requires a large amount of power, so it is essential to develop technology that can reliably and continuously obtain the power of the measuring instrument in the tunnel.

本発明は、上記状況に鑑みて、トンネル内を走行する列車により発生する列車風を利用し、トンネル内で電力を確実に、継続的に得られるようにした、トンネル内の列車風を利用した風力発電方法を提供することを目的とする。 In view of the above situation, the present invention uses a train wind generated by a train that travels in a tunnel, and uses a train wind in the tunnel so that power can be reliably and continuously obtained in the tunnel. An object is to provide a wind power generation method.

本発明によれば、トンネル内の列車風を有効利用することができる。   According to the present invention, the train wind in the tunnel can be used effectively.

列車風は非常に大きなエネルギーを持つが、有効利用されている事例は少ない。上記課題で述べたように、近年の電力事情を鑑みると、このような大きなエネルギーを有効利用できる本発明は日本社会にとって極めて有用であると言える。   Train winds have a great deal of energy, but there are few examples of effective use. As described in the above problem, in view of the recent power situation, it can be said that the present invention capable of effectively using such large energy is extremely useful for Japanese society.

また、トンネル内で確実に、継続的に電力を得ることができる。   Moreover, electric power can be obtained continuously and reliably in the tunnel.

現状では、トンネル内で安定な電力を得ることは非常に難しいが、本発明によれば、安定的に継続して電力を得ることができる。トンネル覆工の変状調査が高度化している状況を踏まえると、本発明によって高度な計測機に供給する電力を安定して確保することができる。   At present, it is very difficult to obtain stable power in a tunnel, but according to the present invention, power can be obtained stably and continuously. Considering the situation where the investigation of the deformation of the tunnel lining is advanced, the present invention can stably secure the power supplied to the advanced measuring instrument.

本発明のトンネル内の列車風を利用した風力発電方法は、トンネル覆工にアーチ状に設置された漏水を導くトンネル樋に、外部に突出した取込口と該取込口に連通する送風ダクトを設け、走行する列車により発生する列車風を前記取込口より取り込み、前記送風ダクトを介して前記トンネル樋内を発電機に導いて電力を得る。 The wind power generation method using the train wind in the tunnel of the present invention is a tunnel duct that introduces water leakage installed in an arch shape on the tunnel lining, and an intake duct that protrudes to the outside and an air duct that communicates with the intake opening the provided a train air generated by a train traveling uptake than the inlet, obtaining a power lead to the generator to the tunnel trough through the air duct.

以下、本発明の実施の形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail.

図１は本発明に係るトンネルと樋を示す模式図である。   FIG. 1 is a schematic view showing a tunnel and a fence according to the present invention.

この図において、１はトンネル、３はトンネル１のトンネル覆工２に配置された樋である。   In this figure, 1 is a tunnel, 3 is a gutter placed on the tunnel lining 2 of the tunnel 1.

図２は本発明の実施例を示すトンネル覆工に配置された樋内の列車風の動きを示す模式図、図３は本発明の実施例を示す列車風の取込口の形状を示す模式図、図４は本発明の実施例を示す列車風による発電の模式図である。   FIG. 2 is a schematic diagram showing the movement of a train wind in a fence arranged in a tunnel lining showing an embodiment of the present invention, and FIG. 3 is a schematic diagram showing the shape of a train wind intake port showing an embodiment of the present invention. FIG. 4 and FIG. 4 are schematic views of power generation by train wind showing an embodiment of the present invention.

これらの図において、４は列車風５の取込口、６は送風ダクト、７はプロペラ、８は発電機、９はリード線（送電用）である。   In these drawings, 4 is an intake for the train wind 5, 6 is an air duct, 7 is a propeller, 8 is a generator, and 9 is a lead wire (for power transmission).

漏水が発生するトンネルの場合、図１のようにトンネル１内にトンネル樋３が設置されることがしばしばある。このトンネル樋３は漏水を導水する効果があるが、本発明では、このトンネル樋３の中に列車風５を、図２に示すようにトンネル樋３より突出した列車風５の取込口４より取り込む。取込口４の形状は、図３に示すように流体力学的に有利なトンネル樋３より外部に突出した翼型にし、取込口４付近で風速が最大になるように設計する。 In the case of a tunnel where water leakage occurs, a tunnel trough 3 is often installed in the tunnel 1 as shown in FIG. Although this tunnel fence 3 has an effect of introducing water leakage, in the present invention, the train wind 5 is introduced into the tunnel fence 3 and the intake 4 of the train wind 5 protruding from the tunnel fence 3 as shown in FIG. Capture more. As shown in FIG. 3, the shape of the intake 4 is an airfoil projecting outward from the tunnel cage 3 which is advantageous in terms of fluid dynamics, and is designed so that the wind speed is maximized in the vicinity of the intake 4.

このように効果的に取り込んだ列車風５を図３に示すように樋３の内部を伝達させ、発電機８に送風する。   As shown in FIG. 3, the train wind 5 thus effectively taken in is transmitted through the interior of the basket 3 and blown to the generator 8.

このようにして、図４のように発電機８へ列車風５を送り、トンネル１の列車風５を利用して電力を発電することが可能となる。   In this way, it is possible to send the train wind 5 to the generator 8 as shown in FIG. 4 and generate electric power using the train wind 5 in the tunnel 1.

従って、トンネル内で確実に、継続的に電力を得ることができる。特に、トンネル内はトンネル外よりも大気密度の変動が小さいと考えられ、列車風が安定的に得られる。従って、トンネル内で確実に、継続的に電力を得ることが可能になる。   Therefore, power can be obtained continuously and reliably in the tunnel. In particular, the fluctuation of the atmospheric density is considered to be smaller inside the tunnel than outside the tunnel, and the train wind can be obtained stably. Therefore, it is possible to reliably obtain power continuously in the tunnel.

なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。   In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.
