Description

本発明は、屋外スイッチギヤに係り、輸送時の高さ制限に対応したベンチレータ構造に関する。 The present invention relates to an outdoor switchgear and relates to a ventilator structure corresponding to a height limitation during transportation.

従来、屋外スイッチギヤ（開閉装置）は結露や雨水を考慮し、屋根の二重化や傾斜付きとする為、屋外スイッチギヤの高さが高くなる傾向にある。更に、特許文献１にあるように、屋外スイッチギヤの冷却の為、屋根にベンチレータ（換気口）を設ける必要があり、これにより、屋外スイッチギヤの全高がさらに高くなる。 Conventionally, the height of the outdoor switchgear tends to be high because the outdoor switchgear (switchgear) has a double roof or a slope in consideration of dew condensation and rainwater. Further, as described in Patent Document 1, it is necessary to provide a ventilator (ventilation port) on the roof for cooling the outdoor switchgear, which further increases the total height of the outdoor switchgear.

特開２０１７―２２９１７３号公報JP-A-2017-229173

屋外スイッチギヤを納品の際には、一般道を利用しトラック等で輸送する必要がある。その際、道路交通法により、輸送高さが規定されている。道路交通法では、高さ制限３．８ｍを超える場合（４．１ｍまで）は、特殊車両通行許可証を提出することで走行可能であるが、その申請の為のリードタイム増加や輸送コストアップに繋がり、さらに、通行できるルートも限定されることになるので、極力、高さ制限３．８ｍを超えないようにするのが得策である。 When delivering outdoor switchgear, it is necessary to transport it by truck or the like using a general road. At that time, the road traffic law stipulates the transportation height. According to the Road Traffic Act, if the height limit exceeds 3.8 m (up to 4.1 m), it is possible to drive by submitting a special vehicle pass permit, but the lead time and transportation cost will increase due to the application. In addition, the routes that can be passed will be limited, so it is a good idea not to exceed the height limit of 3.8 m as much as possible.

昨今、トラックはエアサス仕様車が増えているが、そのために荷台高さが高くなり、結果として、輸送できる積荷高さが、エアサス仕様車でない従来より低く制限される。例えば、従来のトラックの荷台高さが１ｍの場合、積み荷高さは２．８ｍが可能であったが、現在のトラックの荷台高さが１．１ｍとなった場合、積み荷高さは２．７ｍに制限される。従って、従来の全高２．８ｍの屋外スイッチギヤを輸送する場合は、例えば、屋外スイッチギヤから換気口を解体する必要がある。その場合、解体した換気口を梱包し別送し、現地で屋外スイッチギヤに再取付けして組立てる必要があり、工期やコストが増加するという課題があった。 Recently, the number of trucks with air suspension specifications is increasing, but as a result, the height of the loading platform is high, and as a result, the load height that can be transported is limited to a lower level than before, which is not an air suspension specification vehicle. For example, when the loading platform height of a conventional truck is 1 m, the loading height can be 2.8 m, but when the loading platform height of the current truck is 1.1 m, the loading height is 2. Limited to 7m. Therefore, when transporting a conventional outdoor switchgear having a total height of 2.8 m, it is necessary to dismantle the ventilation port from the outdoor switchgear, for example. In that case, it is necessary to pack the disassembled ventilation port, send it separately, and reattach it to the outdoor switchgear at the site to assemble it, which causes a problem that the construction period and cost increase.

本発明は、上記課題に鑑み、輸送時の解体や現地での組立て作業が不要となる、輸送時の高さ制限に対応したベンチレータ構造を有する屋外スイッチギヤを提供することを目的とする。 In view of the above problems, it is an object of the present invention to provide an outdoor switchgear having a ventilator structure corresponding to height restrictions during transportation, which eliminates the need for disassembly and on-site assembly work during transportation.

本発明は、その一例を挙げるならば、屋根板上にベンチレータを設けた屋外スイッチギヤであって、ベンチレータは、通気口と、通気口の周囲を覆う防水カバーと、通気口の上部を覆う通気口カバーを有し、防水カバーは上下に分割可能な第１の防水カバーと第２の防水カバーからなり、第１の防水カバーと第２の防水カバーは、ヒンジを介して展開可能である構成とした。 The present invention is, for example, an outdoor switch gear in which a ventilator is provided on a roof plate, and the ventilator is a vent, a waterproof cover that covers the periphery of the vent, and a vent that covers the upper part of the vent. It has a mouth cover, the waterproof cover consists of a first waterproof cover and a second waterproof cover that can be divided into upper and lower parts, and the first waterproof cover and the second waterproof cover can be deployed via a hinge. And said.

以下、本発明の実施例につき、図面を用いて説明する。 Hereinafter, examples of the present invention will be described with reference to the drawings.

まず、はじめに、本実施例の前提となる、従来の屋外スイッチギヤについて説明する。 First, the conventional outdoor switchgear, which is the premise of this embodiment, will be described.

図１に、従来の屋外スイッチギヤのベンチレータ解体前後の外観図を示す。図１において、（ａ）は、ベンチレータ解体前の屋外スイッチギヤ１００の外観図であり、スイッチギヤの冷却の為に、屋根にベンチレータ１１０を設けている。なお、屋外スイッチギヤ１００の、幅方向、奥行き方向、高さ方向をそれぞれ、Ｘ、Ｙ、Ｚとしたとき、結露や雨水を配水するために、屋根は、幅方向Ｘに傾斜を持たせている。 FIG. 1 shows an external view of a conventional outdoor switchgear before and after dismantling the ventilator. In FIG. 1, (a) is an external view of the outdoor switchgear 100 before dismantling the ventilator, and the ventilator 110 is provided on the roof for cooling the switchgear. When the width direction, depth direction, and height direction of the outdoor switchgear 100 are set to X, Y, and Z, respectively, the roof is inclined in the width direction X in order to distribute dew condensation and rainwater. There is.

図１（ｂ）は、ベンチレータ解体後の屋外スイッチギヤ１００の外観図であり、ベンチレータ１１０を屋外スイッチギヤから解体し取り外すことで屋外スイッチギヤの全体の高さを低くし、輸送時の高さ制限内に収まるようにする。この場合、解体したベンチレータ１１０は梱包し別送し、現地で屋外スイッチギヤに再取付けして組立てる必要があり、工期やコストが増加するという課題があった。 FIG. 1B is an external view of the outdoor switchgear 100 after the ventilator is disassembled. By disassembling and removing the ventilator 110 from the outdoor switchgear, the overall height of the outdoor switchgear is lowered, and the height during transportation is lowered. Try to stay within the limits. In this case, the disassembled ventilator 110 needs to be packed and sent separately, reattached to the outdoor switchgear at the site, and assembled, which has a problem of increasing the construction period and cost.

また、図２に、従来の屋外スイッチギヤのベンチレータ１１０の構成図を示す。図２において、（ａ）は、ベンチレータ１１０の上部から見た外観斜視図である。また、（ｂ）は、ベンチレータ１１０の分解構成図である。（ｂ）に示すように、ベンチレータ１１０は、通気口２１を有し、ゴミ落下防止のための通気口２１の上部を覆う通気口カバー２０と、通気口２１の周囲を覆う防水カバー２３が屋根板２７上に配置されている。また、防水カバー２３内に、通気口２１と雨受け２４と防じんフィルタ２５と止水板２６を有し、止水板２６が屋根板２７に接合されている。また、通気口カバー保持金具２２で通気口カバー２０が防水カバー２３に保持されている。 Further, FIG. 2 shows a configuration diagram of a conventional outdoor switchgear ventilator 110. In FIG. 2, (a) is an external perspective view seen from the upper part of the ventilator 110. Further, (b) is an exploded configuration diagram of the ventilator 110. As shown in (b), the ventilator 110 has a vent 21, and the vent cover 20 that covers the upper part of the vent 21 for preventing dust from falling and the waterproof cover 23 that covers the periphery of the vent 21 are roofs. It is arranged on the plate 27. Further, the waterproof cover 23 has a vent 21, a rain receiver 24, a dust filter 25, and a waterstop plate 26, and the waterstop plate 26 is joined to the roof plate 27. Further, the vent cover 20 is held by the waterproof cover 23 by the vent cover holding metal fitting 22.

図２（ｃ）は、（ａ）のＡ－Ａ断面図であり、ベンチレータ１１０の幅方向Ｘの断面を示す。前述したように、屋根は、幅方向Ｘに傾斜を持たせているので、屋根板２７は傾斜しており、風雨によるベンチレータ１１０への侵入水は点線で示すように、雨受け２４を介して隙間２９から排水される。 FIG. 2C is a cross-sectional view taken along the line AA of FIG. 2A, showing a cross section of the ventilator 110 in the width direction X. As described above, since the roof is inclined in the width direction X, the roof plate 27 is inclined, and the water entering the ventilator 110 due to wind and rain is indicated by the dotted line through the rain receiver 24. It is drained from the gap 29.

図２（ｄ）は、（ａ）のＢ－Ｂ断面図であり、ベンチレータ１１０の奥行方向Ｙの断面を示す。屋外スイッチギヤ内の空気は、点線で示すように、防じんフィルタ２５を介して通気口２１から排気される。なお、固定座２８により、防水カバー２３が屋根板２７に固定されている。 FIG. 2D is a cross-sectional view taken along the line BB of FIG. 2A, showing a cross section of the ventilator 110 in the depth direction Y. The air in the outdoor switchgear is exhausted from the vent 21 via the dust filter 25 as shown by the dotted line. The waterproof cover 23 is fixed to the roof plate 27 by the fixed seat 28.

このように、従来の、輸送時の高さ制限内に収まるように屋外スイッチギヤのベンチレータ１１０を解体することで生じる種々の課題を解消するために、本実施例では、防水カバーを上下に分割し、ヒンジを介して分割した防水カバーそれぞれを展開可能とする構成とした。以下、その詳細について説明する。 As described above, in order to solve various problems caused by disassembling the ventilator 110 of the outdoor switchgear so as to be within the height limitation during transportation in the present embodiment, the waterproof cover is divided into upper and lower parts in this embodiment. However, each waterproof cover divided via a hinge can be deployed. The details will be described below.

図３は、本実施例におけるベンチレータの構成図である。図３において、（ａ）は本実施例におけるベンチレータの構成の概念を示す図である。（ａ）に示すように、本実施例におけるベンチレータ１２０は、屋外スイッチギヤ１００を輸送時には白抜き矢印の右側に示すように、防水カバーを上下に分割し、ヒンジを取り付け展開することで輸送時の高さを低減する構成とする。 FIG. 3 is a block diagram of the ventilator in this embodiment. In FIG. 3, (a) is a diagram showing the concept of the configuration of the ventilator in this embodiment. As shown in (a), in the ventilator 120 in the present embodiment, when the outdoor switchgear 100 is transported, the waterproof cover is divided into upper and lower parts as shown on the right side of the white arrow, and a hinge is attached and deployed to deploy the outdoor switchgear 100 during transportation. It is configured to reduce the height of the.

図３（ｂ）は本実施例におけるベンチレータ１２０の使用時のベンチレータ１１０の幅方向Ｘの断面図である。図３（ｂ）において、図２（ｃ）と同じ構成は同じ符号を付し、その説明は省略する。図３（ｂ）において、図２（ｃ）と異なる点は、防水カバー２３を３１と３２の上下に分割し、それらをヒンジ３４で開閉可能に接続した点である。また、図３（ｂ）に示すように、防水カバー３２にはフランジ３３を設け、防水カバー３１と３２を重ねる時の接続部として利用し、防水性を確保する。なお、図２（ｄ）と同様に、防水カバー３１は固定座２８により屋根板２７に固定されている。 FIG. 3B is a cross-sectional view taken along the width direction X of the ventilator 110 when the ventilator 120 in this embodiment is used. In FIG. 3 (b), the same configurations as in FIG. 2 (c) are designated by the same reference numerals, and the description thereof will be omitted. In FIG. 3B, the difference from FIG. 2C is that the waterproof cover 23 is divided into upper and lower parts of 31 and 32, and they are connected by a hinge 34 so as to be openable and closable. Further, as shown in FIG. 3B, the waterproof cover 32 is provided with a flange 33, which is used as a connecting portion when the waterproof cover 31 and 32 are overlapped to ensure waterproofness. As in FIG. 2D, the waterproof cover 31 is fixed to the roof plate 27 by the fixed seat 28.

図３（ｃ）は輸送時の防水カバー３１と３２を展開して開いた状態の幅方向Ｘの断面図である。図３（ｃ）に示すように、輸送時はヒンジ３４を中心として防水カバー３１と３２を開き、防水カバー３２側を屋根板２７に取り付けた受け金具３５で保持する。これにより、屋根傷防止を実現できる。なお、自重やトラック搭載時にはシートがある為、防水カバー３２は固定しなくてもよい。 FIG. 3C is a cross-sectional view taken along the width direction X of the waterproof covers 31 and 32 during transportation in an unfolded and open state. As shown in FIG. 3C, during transportation, the waterproof covers 31 and 32 are opened around the hinge 34, and the waterproof cover 32 side is held by the receiving metal fitting 35 attached to the roof plate 27. This makes it possible to prevent roof scratches. The waterproof cover 32 does not have to be fixed because there is a seat due to its own weight or when it is mounted on a truck.

また、ヒンジ３４は、防水カバー３１と３２の側面よりも外側に突出する形状とすることで、ヒンジ３４がフランジ３３と干渉せず、また展開時に通気口カバー２０が防水カバー３１と干渉しない。 Further, by forming the hinge 34 so as to project outward from the side surfaces of the waterproof covers 31 and 32, the hinge 34 does not interfere with the flange 33, and the vent cover 20 does not interfere with the waterproof cover 31 when deployed.

また、雨受け２４は、防水カバー３１側に固定すると高さ寸法が目標オーバーとなる為、防水カバー３２側に固定する。これは、防水カバー３２は高くなっても、屋根板２７の傾斜により、屋根板２７の低い方向に防水カバー３２を展開するので、その高さを吸収できるためである。 Further, if the rain receiver 24 is fixed to the waterproof cover 31 side, the height dimension exceeds the target, so the rain receiver 24 is fixed to the waterproof cover 32 side. This is because even if the waterproof cover 32 becomes high, the height of the waterproof cover 32 can be absorbed because the waterproof cover 32 is deployed in the lower direction of the roof plate 27 due to the inclination of the roof plate 27.

また、防水カバー３２のヒンジ３４と反対側に位置するフランジ３３の高さ方向の幅を広げることができるため、ヒンジ３４と反対側に位置するフランジ３３を使って使用時はボルトまたはスナップ錠などで固定する。 Further, since the width in the height direction of the flange 33 located on the opposite side of the hinge 34 of the waterproof cover 32 can be widened, bolts or snap locks or the like can be used when using the flange 33 located on the opposite side of the hinge 34. Fix with.

また、新たな効果として、従来、防じんフィルタ２５の清掃や交換の際は、ベンチレータを解体する必要があったが、本実施例における防水カバーのヒンジ展開の構成により、簡単に防じんフィルタ２５の清掃や交換を行うことが可能となる。 In addition, as a new effect, it was necessary to disassemble the ventilator when cleaning or replacing the dustproof filter 25 in the past, but the dustproof filter 25 can be easily cleaned by the hinge deployment configuration of the waterproof cover in this embodiment. And can be exchanged.

以上のように、本実施例によれば、輸送時の高さ制限に対応したベンチレータ構造を有する屋外スイッチギヤを提供できる。 As described above, according to the present embodiment, it is possible to provide an outdoor switchgear having a ventilator structure corresponding to a height limitation during transportation.

図４は本実施例におけるベンチレータの構成の概念を示す図である。図４に示すように、本実施例におけるベンチレータ１３０は、屋外スイッチギヤ１００を輸送時には白抜き矢印の右側に示すように、ベンチレータ１３０を屋根板で構成される屋根の内部に収納するように構成する。具体的には、ベンチレータ１３０を構成する防水カバーを屋根に設けた突起に爪で引っかける構成や、屋根にボルトで固定する等の構成で実現できる。 FIG. 4 is a diagram showing the concept of the configuration of the ventilator in this embodiment. As shown in FIG. 4, the ventilator 130 in this embodiment is configured to house the outdoor switchgear 100 inside a roof made of a roof plate as shown on the right side of the white arrow during transportation. do. Specifically, the waterproof cover constituting the ventilator 130 can be hooked on a protrusion provided on the roof with a claw, or fixed to the roof with a bolt.

このように、本実施例によれば、輸送時の屋外スイッチギヤ１００の高さを低減することが可能となる。 As described above, according to the present embodiment, it is possible to reduce the height of the outdoor switchgear 100 during transportation.

As shown in FIG. 6, the ventilator 150 in this embodiment has a nested structure in which the upper portion of the waterproof cover portion is smaller than that of the lower portion, and the outdoor switch gear 100 is on the right side of the white arrow when the outdoor switch gear 100 is transported. As shown, a small waterproof cover portion is housed in the large waterproof cover portion, and the space through which air flows when the ventilator 150 is used, that is, the space constituting the vent is narrowed.

図７は本実施例における入れ子構造の具体的な構成例であり、（ａ）は、４辺のうちの対抗する２辺が台形形状である場合のベンチレータ１５０の収納前後を示し、（ｂ）は、４辺の全てが台形形状である場合のベンチレータ１５０の収納前後を示し、（ｃ）は、（ａ）および（ｂ）におけるベンチレータ１５０の収納前後の断面を示した図である。 FIG. 7 shows a specific configuration example of the nested structure in this embodiment, in which (a) shows the front and rear of the ventilator 150 when two opposing sides of the four sides are trapezoidal, and (b). Is a diagram showing before and after storage of the ventilator 150 when all four sides are trapezoidal, and (c) is a diagram showing cross sections of the ventilator 150 before and after storage in (a) and (b).

なお、具体的には、ベンチレータ１５０を構成する防水カバーを複数の入れ子構造の部材で構成し、それぞれを爪で引っかける構成や、ボルトで固定する等の構成で実現できる。また、図６、図７は２段の入れ子構造を示しているが、３段以上でも構わない。 Specifically, the waterproof cover constituting the ventilator 150 can be configured by a plurality of members having a nested structure, and each of them can be hooked with a claw or fixed with a bolt. Further, although FIGS. 6 and 7 show a two-stage nested structure, three or more stages may be used.

このように、本実施例によれば、輸送時の屋外スイッチギヤ１００の高さを低減することが出来る。 As described above, according to the present embodiment, the height of the outdoor switchgear 100 during transportation can be reduced.

図８は本実施例におけるベンチレータの構成の概念を示す図である。図８に示すように、本実施例におけるベンチレータ１６０は、図６と同様に防水カバー部が入れ子構造となっているが、上部が下部に比べてより大きい構成の入れ子構造となっている。そして、図６と同様に、屋外スイッチギヤ１００を輸送時には白抜き矢印の右側に示すように、大きな防水カバー部内に小さな防水カバー部を収納しベンチレータ１６０の使用時の空気が流通する空間を狭めるように構成する。 FIG. 8 is a diagram showing the concept of the configuration of the ventilator in this embodiment.
