Description

【０００１】
【産業上の利用分野】
本発明は、集電装置用カバー装置に係り、特に高速で走行する接触集電方式の鉄道車両に好適な集電装置用カバー装置に関するものである。
【０００２】
【従来の技術】
従来の技術としては、特開平３−５００６５号に記載のように、パンタグラフ式集電装置（以下単にパンタグラフという）の周囲を囲う集電装置カバーは車両の屋根に直接固定され、かつ集電装置カバーの上端は車両基礎限界（架線より下５００ｍｍ）一杯の高さにある。一方、屋根のレール面からの高さは車両の高速化に伴って車両の空気抵抗や空力音を低減するため益々低くなる傾向にある。従って、集電装置用カバーの屋根からの高さ寸法は益々大きくなる傾向にある。
【０００３】
【発明が解決しようとする課題】
従来技術においては、車両が高速化のために低車高化するとき、集電装置用カバーの高さ寸法は益々大きくなるので、パンタグラフ位置における流速比（パンタグラフ位置の流速と主流速の比）は小さくなりパンタグラフの揚力、空力音、空気抵抗は小さくなるが、集電装置用カバーの前面々積は益々大きくなるので、集電装置用カバー自体の空力音、空気抵抗は益々大きくなるという問題がある。
【０００４】
本発明は、集電装置用カバーの空力音、空気抵抗を小さくすると同時に、パンタグラフ位置における流速比をより小さくしてパンタグラフの揚力、空力音、空気抵抗をより小さくする集電装置用カバー装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明は、集電装置用カバーの空力音、空気抵抗を小さくすると同時に、パンタグラフ位置における流速比をより小さくする手段として、碍子で支持されその底面と屋根面の間に空間を有して車両の上方向基礎限界を越えてパンタグラフの周囲を囲うカバー本体を備える。
【０００６】
【作用】
本発明の技術的手段によれば、カバー本体が碍子で支持されているので、カバー本体の上端を車両の上方向基礎限界を越えて従来より架線に接近させて設けることができ、従って架線とカバー本体上端の上下距離は従来よりも小さく、パンタグラフ位置で従来と同じ流速比を得る場合、カバー本体の全高、全長を従来よりも小さくすることが出来る。また、カバー本体の全高が小さくなるのでカバー本体の底面と屋根面の間に空間が設けられる。走行風は屋根面に沿ってこの空間に直線的に流れこむと同時に、カバー本体の前面の傾斜に沿って流れ、パンタグラフ位置の高さよりも高いところで主流速をもつ流れとなる。このとき、カバー本体の前面の下先端における流れに、従来の屋根面とカバー前面とがつながった場合のような流れのよどみがなくなり、従ってカバー本体前面に沿う流れは前面傾斜に沿って忠実に流れるようになり（見掛上前面傾斜角がより大きくなったことに相当）、主流速の流線はパンタグラフからの高さがより高いところを通るようになる。これにより、パンタグラフすり板点での流速比はより小さくなる。カバー本体の全高、全長が小さくなることによってカバー本体の空力音、空気抵抗を低減でき、かつパンタグラフ位置での流速比がより小さくなることによってパンタグラフの揚力、空力音、空気抵抗を低減することが出来る。
また、支持手段は、支持カバー本体を昇降可能に支持し、該カバー本体の上端が非集電時における最小絶縁距離だけ架線から離れた位置に下降させ得る昇降機構を備えている。このとき、支持カバー本体を小形化すれば、空力音、空気抵抗を従来よりも小さくすることが出来る。したがって、昇降機構を支持カバー本体の内側に設ければ、車両の屋根を特に改造する必要がなく既存の車両へも適用し易い効果がある。
【０００７】
【実施例】
以下、本発明の実施例を図１ないし図６を用いて説明する。１は架線、２はパンタグラフで、パンタグラフ２を構成するものとして、２ａは架線１と接触して集電するすり板、２ｂは２枚のすり板２ａ間で左右に突出しているパンタグラフのホーン、２ｃはすり板２ａを支持する枠組、２ｄは枠組２ｃを支持する台座である。３は車両の屋根、４はパンタグラフの台座２ｄを屋根３上で支持し、かつ屋根３を電気的に絶縁する流線型のパンタグラフ用碍子である。５は車両走行方向の前面が前下りの傾斜面を有し、下辺がパンタグラフ２の下部を覆った状態で前面の上端が車両の上方向基礎限界の上方に位置しているカバー本体、６はカバー本体５を昇降可能に支持し、カバー本体５の上端が非集電時における最小絶縁距離だけ架線から離れた位置に下降させうるパンタグラフ式昇降機構、７は昇降機構６を介してカバー本体５を屋根３上で支持し、かつ屋根３をカバー本体５から電気的に絶縁すると共に、カバー本体５を屋根３との間に隙間を設けて支持する流線型のカバー用碍子である。さらに、ｈ₁₀は車両の上方向基礎限界、ｈ₁₁は非集電時の必要最小絶縁距離、ｈ₁は集電時の架線１とカバー本体５の上端との上下間隔、ｈ₂はカバー本体５自体の高さで、その高さ寸法はカバー本体５の下辺がパンタグラフ２の下部を覆った状態で、前面によって導かれる走行風の減速域がパンタグラフすり板２ａの上方に位置するようにした寸法である。ｈ₃はカバー本体５の底面と屋根３の上下間隔、ｌはカバー本体５の上端の前後長さ、θはカバー本体５の前面傾斜角である。
【０００８】
以上の構成によれば、走行風の主流速Ｕ_oの流線は図５（ｂ）に示すように上下間隔ｈ₃の空間を後方へ直進すると同時に、カバー本体５の傾斜角θをもった前面に沿って斜め上方へ進む。この主流速Ｕ_Oの流速はすり板２ａの高さ点Ｂよりも上方を通るので、Ｂ点における流速比は１よりも小さい。カバー本体５を屋根３上でカバー用碍子７の上に支持しているので、カバー本体５の上端の架線１に対する間隔ｈ₁を従来のカバー本体５ａ（図５（ａ））における最小絶縁距離ｈ₁₁（５００ｍｍ）よりも小さく（例えば２００ｍｍ）することが出来る。前面傾斜角θが等しく、Ｂ点における流速比も変えないとすると、間隔ｈ₁が小さくできるときカバー本体５の高さｈ₂もほぼｈ₁／ｈ₁₀に比例してｈ₂₀・ｈ₁／ｈ₁₀に小さくすることが出来る。カバー本体５の上端前後長さｌもほぼｌ_O・ｈ₁／ｈ₁₀に小さくすることが出来る。従って、カバー本体５が小形化されるのでカバー本体自体の空力音を４ｄＢ（Ａ）程度、空気抵抗を従来よりも６０％程度小さくすることが出来る。カバー用碍子７およびパンタグラフ用碍子４は流線型としているので騒音の発生は極く僅かである。
【０００９】
一方、図５に示すように屋根３上に直接カバー本体５ａを設けている従来例では、カバー本体前面下端と屋根との結合点Ａに気流のよどみが生じ、そのため主流速Ｕ_Oの流線の傾きはカバー本体５ａの前面傾斜角θよりも小さくなる。これに対して、前記カバー本体５では気流の主流速Ｕ_Oの流線は上下間隔ｈ₃の空間を後方へ直進するために、その傾斜角θをもつ前面に沿う流れは下方へ引張られて前面下端点Ａにおけるよどみがなくなり、前面に沿う主流速Ｕ_Oの流線の傾斜角は前面傾斜角θに等しくなって従来よりも流線の傾斜角は大きくなる。このため、主流速Ｕ_Oの流線が通る高さ比ｂ／ａ（ｂは主流速Ｕ_Oのすり板点Ｂからの高さ、ａは主流速Ｕ_Oのカバー本体５の上端からの高さ）は従来の高さ比ｂ_O／ａ_O（ｂ_Oは主流速Ｕ_Oのすり板点Ｂからの従来高さ、ａ_Oは主流速Ｕ_Oの従来カバー本体５ａ上端からの高さ）よりも大きくなり、すり板点Ｂにおける流速比は従来よりも小さくなる。従って、パンタグラフ２に当る気流の流速比が小さくなるので、パンタグラフ２の揚力、空気抵抗を従来よりも３０％程度、空力音を５ｄＢ（Ａ）程度小さくすることが出来る。また、カバー本体５の角度θや平面、側面形状を適切にすればより一層揚力、空力音、空気抵抗を小さくすることが出来る。
【００１０】
集電しない時は、図６のようにカバー本体５もパンタグラフ式昇降機構６によって基礎限界ｈ₁₀まで下降させられる。このときもカバー本体５は小形化されているので、空力音、空気抵抗は従来よりも小さくすることが出来る。本実施例によれば、パンタグラフ式昇降機構６をカバー本体５の内側に設けているので、屋根３を特に改造する必要がなく既存の車両へも適用し易い効果がある。
【００１１】
本発明の第２の実施例では、図７に示すように、カバー本体５ｂをカバー用碍子７ａに固定し、パンタグラフ式昇降機構６ａをカバー用碍子７ａの下に設けている。本実施例によれば、昇降機構６ａを車体側（対地側）に設けることから、その駆動手段への動力供給において絶縁を考慮する必要がなく、構造の簡略化が図れる。
【００１２】
本発明の第３の実施例では、図８および図９に示すように、カバー本体５の車両走行方向前方の屋根３上に、カバー本体５より絶縁距離（２００〜３００mm）だけ離してその高さが隙間寸法ｈ₃より短い流線型の前カバー体８ａを設けてある。本実施例によれば、前カバー体８ａがパンタグラフ用碍子４、カバー用碍子７の前側にあるので、両碍子４、７から僅かの空力音が発生する場合でも両碍子４、７に当る風を弱めることができてより騒音を低減できる。
【００１３】
本発明の第４の実施例では、図１０ないし図１２に示すように、カバー本体５の側面より所定の絶縁距離（２００〜３００ｍｍ）だけ離して、その高さは隙間ｈ₃より小さく、長さはカバー本体５の前後長さ程度である流線型の側面カバー体８を車体幅方向両側に設けてある。本実施例によれば、側面カバー体８がパンタグラフ用碍子４、カバー用碍子７の側面にあるので、両碍子から僅かの空力音が発生する場合でも側方に対してこの空力音を遮音することができ、騒音をより低減できる効果がある。
【００１４】
【発明の効果】
本発明は、カバー用碍子の上にカバー本体を設けていて、カバー本体を車両の基礎限界を越えて架線に接近させることができるとともに小形化できるので、該カバー本体の空力音、空気抵抗を小さくできる。また、カバー本体の底面と屋根の間に空間を設けることができるので、パンタグラフすり板点における流速比をより小さくでき、パンタグラフの揚力、空力音、空気抵抗を小さくすることができる効果がある。

[Industrial application fields]
The present invention relates to a cover device for a current collector, and more particularly, to a cover device for a current collector that is suitable for a contact-collection-type railway vehicle that travels at a high speed.
[0002]
[Prior art]
As a conventional technique, as described in JP-A-3-50065, a current collector cover surrounding a pantograph current collector (hereinafter simply referred to as a pantograph) is directly fixed to the roof of the vehicle, and the current collector The upper end of the cover is at the full height of the vehicle foundation limit (500mm below the overhead line). On the other hand, the height from the rail surface of the roof tends to become lower and lower in order to reduce the air resistance and aerodynamic noise of the vehicle as the vehicle speed increases. Therefore, the height dimension of the current collector cover from the roof tends to increase more and more.
[0003]
[Problems to be solved by the invention]
In the prior art, when the vehicle is lowered to increase the speed, the height of the cover for the current collector becomes larger, so the flow rate ratio at the pantograph position (ratio between the flow rate at the pantograph position and the main flow rate) The pantograph lift, aerodynamic sound, and air resistance become smaller, but the front surface area of the current collector cover becomes larger and the aerodynamic sound and air resistance of the current collector cover itself become larger. There is.
[0004]
The present invention provides a cover device for a current collector that reduces the aerodynamic sound and air resistance of the cover for the current collector, and at the same time reduces the flow rate ratio at the pantograph position, thereby reducing the lift, aerodynamic sound, and air resistance of the pantograph. The purpose is to provide.
[0005]
[Means for Solving the Problems]
The present invention provides a vehicle having a space between a bottom surface and a roof surface that is supported by an insulator as means for reducing the aerodynamic sound and air resistance of the cover for the current collector, and at the same time reducing the flow rate ratio at the pantograph position. A cover body that surrounds the perimeter of the pantograph beyond the upper basic limit.
[0006]
[Action]
According to the technical means of the present invention, since the cover main body is supported by the insulator, the upper end of the cover main body can be provided closer to the overhead wire than the conventional upper limit beyond the upper basic limit of the vehicle. The vertical distance of the upper end of the cover body is smaller than before, and when the same flow velocity ratio is obtained at the pantograph position, the overall height and overall length of the cover body can be made smaller than before. Further, since the overall height of the cover body is reduced, a space is provided between the bottom surface of the cover body and the roof surface. The traveling wind linearly flows into this space along the roof surface, and at the same time, flows along the inclination of the front surface of the cover body, and has a main flow velocity at a position higher than the height of the pantograph position. At this time, the flow at the lower front end of the front surface of the cover body is free from the stagnation of the flow as in the case where the conventional roof surface and the front surface of the cover are connected. It will flow (equivalent to the apparent increase in the front tilt angle), and the streamline of the main flow velocity will pass through where the height from the pantograph is higher. As a result, the flow rate ratio at the pantograph slip plate point becomes smaller. The aerodynamic sound and air resistance of the cover body can be reduced by reducing the overall height and overall length of the cover body, and the lift, aerodynamic sound and air resistance of the pantograph can be reduced by reducing the flow rate ratio at the pantograph position. I can do it.
The support means includes a lifting mechanism that supports the support cover body so that the support cover body can be moved up and down, and that the upper end of the cover body can be lowered to a position away from the overhead line by a minimum insulation distance during non-current collection. At this time, if the support cover body is downsized, the aerodynamic sound and the air resistance can be made smaller than in the prior art. Therefore, if the elevating mechanism is provided inside the support cover body, there is no need to particularly modify the roof of the vehicle, and there is an effect that it can be easily applied to existing vehicles.
[0007]
【Example】
Embodiments of the present invention will be described below with reference to FIGS. 1 is an overhead wire, 2 is a pantograph, and constitutes the pantograph 2, 2a is a sliding plate that contacts the overhead wire 1 and collects current, 2b is a pantograph horn protruding left and right between the two sliding plates 2a, 2c is a frame that supports the sliding plate 2a, and 2d is a pedestal that supports the frame 2c. 3 is a roof of a vehicle, 4 is a streamlined pantograph insulator that supports a pantograph pedestal 2d on the roof 3 and electrically insulates the roof 3. 5 is a cover body in which the front surface in the vehicle traveling direction has a front and lower inclined surface, the lower side covers the lower part of the pantograph 2, and the upper end of the front surface is located above the upper basic limit of the vehicle. A pantograph type lifting mechanism that supports the cover body 5 so that the cover body 5 can be raised and lowered, and the upper end of the cover body 5 can be lowered to a position away from the overhead line by a minimum insulation distance when not collecting current. Is a streamlined cover insulator that supports the roof 3 electrically from the cover body 5 and supports the cover body 5 with a gap between the roof 3 and the roof 3. Furthermore, h ₁₀ is the upper basic limit of the vehicle, h ₁₁ is the minimum insulation distance required when current is not collected, h ₁ is the vertical distance between the overhead wire 1 and the upper end of the cover body 5 during current collection, and h ₂ is the cover body. The height dimension of the cover body 5 is such that the lower side of the cover body 5 covers the lower part of the pantograph 2, and the deceleration area of the traveling wind guided by the front surface is located above the pantograph sliding plate 2a. Dimensions. h ₃ is the vertical distance between the bottom surface of the cover body 5 and the roof 3, l is the front-rear length of the upper end of the cover body 5, and θ is the front inclination angle of the cover body 5.
[0008]
According to the above configuration, the streamlines of the main flow velocity U _o of the traveling wind at the same time straight space vertical distance h ₃ as shown in FIG. 5 (b) to the rear, with a tilt angle of the cover body 5 theta Proceed diagonally upward along the front. Since the flow velocity of the main flow velocity U _O passes above the height point B of the sliding plate 2a, the flow velocity ratio at the point B is smaller than 1. Since the cover body 5 is supported on the cover 3 on the cover 3, the distance h ₁ between the upper end of the cover body 5 and the overhead wire 1 is the minimum insulation distance in the conventional cover body 5 a (FIG. 5A). It can be smaller (for example, 200 mm) than h ₁₁ (500 mm). Equal front inclination angle theta, When not change the flow rate ratio at the point B, in proportion to approximately h ₁ / h ₁₀ height h ₂ of the cover body 5 even when the gap h ₁ can be reduced h ₂₀ · h ₁ / it can be reduced to h _10. The length l before and after the upper end of the cover body 5 can also be reduced to approximately l _O · h ₁ / h ₁₀ . Accordingly, since the cover body 5 is reduced in size, the aerodynamic sound of the cover body itself can be reduced by about 4 dB (A), and the air resistance can be reduced by about 60% compared to the conventional case. Since the cover insulator 7 and the pantograph insulator 4 are streamlined, the generation of noise is very small.
[0009]
Meanwhile, in the conventional example is provided directly cover body 5a on the roof 3, as shown in FIG. 5, the stagnation of the air flow occurs in the coupling point A of the cover body front lower end roof streamline therefor mainstream velocity U _O Is smaller than the front surface inclination angle θ of the cover body 5a. On the other hand, in the cover body 5, the streamline of the main flow velocity U _O of the air stream goes straight backward in the space of the vertical interval h ₃ , so that the flow along the front surface having the inclination angle θ is pulled downward. The stagnation at the front lower end point A disappears, the inclination angle of the streamline of the main flow velocity U _O along the front surface becomes equal to the front surface inclination angle θ, and the inclination angle of the streamline becomes larger than before. For this reason, the height ratio b / a through which the streamline of the main flow velocity U _O passes (b is the height of the main flow velocity U _{O from} the sliding plate point B, and a is the height of the main flow velocity U _O from the upper end of the cover body 5. is) height ratio of conventional b _{_{_O}} / a _O (b _O mainstream velocity U _O contact strip points conventional height from B of the height from the conventional cover body 5a upper end of a _O mainstream velocity U _O) The flow rate ratio at the sliding plate point B becomes smaller than that of the conventional one. Therefore, since the flow rate ratio of the airflow hitting the pantograph 2 is reduced, the lift and air resistance of the pantograph 2 can be reduced by about 30% and the aerodynamic sound can be reduced by about 5 dB (A). Further, if the angle θ, the plane, and the side surface shape of the cover body 5 are appropriate, the lift force, aerodynamic sound, and air resistance can be further reduced.
[0010]
When the current is not collected, the cover body 5 is also lowered to the basic limit h ₁₀ by the pantograph type lifting mechanism 6 as shown in FIG. Also at this time, since the cover main body 5 is miniaturized, the aerodynamic sound and the air resistance can be made smaller than before. According to the present embodiment, since the pantograph type lifting mechanism 6 is provided inside the cover body 5, there is no need to particularly modify the roof 3, and there is an effect that it can be easily applied to existing vehicles.
[0011]
In the second embodiment of the present invention, as shown in FIG. 7, the cover body 5b is fixed to the cover insulator 7a, and the pantograph lift mechanism 6a is provided below the cover insulator 7a. According to the present embodiment, since the elevating mechanism 6a is provided on the vehicle body side (ground side), it is not necessary to consider insulation in power supply to the driving means, and the structure can be simplified.
[0012]
In the third embodiment of the present invention, as shown in FIGS. 8 and 9, the cover body 5 is separated from the cover body 5 by an insulation distance (200 to 300 mm) on the roof 3 in the vehicle traveling direction. Saga is provided with a short streamlined front cover 8a than the gap dimension h _3. According to the present embodiment, since the front cover body 8a is on the front side of the pantograph insulator 4 and the cover insulator 7, even if a slight aerodynamic sound is generated from both the insulators 4, 7, the wind hitting the insulators 4, 7 Can be weakened and noise can be further reduced.
[0013]
In the fourth embodiment of the present invention, as shown in FIGS. 10 to 12, it is separated from the side surface of the cover body 5 by a predetermined insulation distance (200 to 300 mm), and its height is smaller than the gap h ₃ and is long. A streamlined side cover body 8 that is approximately the length in the front-rear direction of the cover body 5 is provided on both sides in the vehicle body width direction. According to this embodiment, since the side cover body 8 is on the side surfaces of the pantograph insulator 4 and the cover insulator 7, even if a slight aerodynamic sound is generated from both insulators, the aerodynamic sound is insulated from the side. This is effective in reducing noise.
[0014]
【The invention's effect】
In the present invention, the cover main body is provided on the cover insulator, and the cover main body can be approached to the overhead wire beyond the basic limit of the vehicle and can be miniaturized. Therefore, the aerodynamic sound and air resistance of the cover main body can be reduced. Can be small. In addition, since a space can be provided between the bottom surface of the cover body and the roof, the flow rate ratio at the pantograph sliding plate point can be further reduced, and the lift, aerodynamic sound, and air resistance of the pantograph can be reduced.
