Description
本発明は、発電装置に関し、特に発電装置外箱に設けられる点検用扉に関する。 The present invention relates to a power generation device, and more particularly to an inspection door provided in a power generation device outer box.
従来、発電装置の外箱の扉構造としては、特許文献１に示されるように、外箱の側面と扉とをヒンジで連結し、保守点検時等にはヒンジを支点に扉を外側に開放するものが一般的であった。また、特許文献２には、外開き扉の開閉スペースを小さくするための機構として、一端を本体ケース内側、他端を扉内側に回転自在に取り付けられた２本の支持アームを備え、扉を上下方向の円弧状にスライドさせるようにしたエンジン駆動型作業機用扉の開閉機構が提示されている。 Conventionally, as the door structure of the outer box of the power generator, as shown in Patent Document 1, the side of the outer box and the door are connected by a hinge, and the door is opened to the outside with the hinge as a fulcrum during maintenance inspection, etc. What you do was common. In addition, Patent Document 2 includes two support arms that are rotatably mounted at one end inside the main body case and at the other end inside the door as a mechanism for reducing the opening and closing space of the outer opening door. An opening / closing mechanism for an engine-driven work machine door that is slid in a vertical arc shape is proposed.
さらに、外開き構造以外の扉の例として、特許文献３には、３枚のスライド式扉を設け、そのうちの２枚の扉は互いに隔離するように横方向にスライドし、残りの扉は前記２枚の扉のいずれかに重なり合うように横方向にスライドするスライド式扉付配電盤が提示されている。この例では、スライド式扉を３枚にすることで、２枚の場合よりも配電盤の盤幅を狭くすることができる。 Furthermore, as an example of a door other than the outer opening structure, Patent Document 3 provides three sliding doors, two of which slide laterally so as to be separated from each other, and the remaining doors are the above-mentioned doors. A switchboard with a sliding door that slides in a lateral direction so as to overlap one of the two doors is presented. In this example, by using three sliding doors, the panel width of the switchboard can be made narrower than in the case of two.
特許文献１に示されるような外開き構造の扉の場合、外開き時の開放寸法を含む広い設置スペースが必要となる問題があった。また、保守点検時には扉を外側に開いた状態であるため、外気の流れを扉に受け、ヒンジや扉の過開き防止ストッパーが破損することがあった。特許文献２に提示された開閉機構では、設置スペースを小さくすることはできるが、外開きであるため、扉が外力を受ける点では特許文献１と同じである。 In the case of a door having an outward opening structure as disclosed in Patent Document 1, there is a problem that a wide installation space including an open dimension at the time of outward opening is required. In addition, since the door is open to the outside at the time of maintenance inspection, the flow of outside air is received by the door, and the hinge and the over-opening prevention stopper of the door may be damaged. In the opening / closing mechanism presented in Patent Document 2, the installation space can be reduced, but since the door is open, it is the same as Patent Document 1 in that the door receives an external force.
また、特許文献３のようなスライド式扉では、外開き時の解放寸法を考慮する必要がなく、扉開放時に受ける外気の影響によるヒンジやストッパーの破損の問題は起こらない。しかし、発電装置の場合、外箱の材質は主に鋼板が用いられること、エンジンや発電機の騒音を減少させるため外箱に吸音材を貼り付けることから、扉の重量が大きくなる。このため、特許文献３のようなスライド式扉では、扉を横方向にスライドさせるのに労力を要するという問題があった。 Further, in the sliding door as in Patent Document 3, it is not necessary to consider the release dimension when the door is opened, and the problem of damage to the hinge and the stopper due to the influence of the outside air received when the door is opened does not occur. However, in the case of a power generation device, the weight of the door increases because a material of the outer box is mainly a steel plate, and a sound absorbing material is attached to the outer box in order to reduce the noise of the engine and the generator. For this reason, in the sliding door like patent document 3, there existed a problem that an effort was required to slide a door to a horizontal direction.
本発明は、上記のような課題を解決するためになされたものであり、外開き構造の扉に比べ設置スペースが小さく、扉開放時の外気の影響による扉部品の破損が起こらず、且つ扉の開閉が容易な外箱を有する発電装置を得ることを目的とする。 The present invention has been made in order to solve the above-described problems, and has a smaller installation space than a door with an open door structure, the door parts are not damaged by the influence of outside air when the door is opened, and the door. An object of the present invention is to obtain a power generator having an outer box that can be easily opened and closed.
本発明に係る発電装置は、外箱の内部にエンジン、発電機、および制御盤が設置され、エンジンにより発電機を駆動して電力を発生する発電装置であって、外箱の側面に設けられローラー機構により横方向にスライド可能であり、吸音材が貼り付けられた内扉と、内扉の外側に設けられ外扉用下レール部に沿って横方向にスライド可能な外扉とを備え、外扉の下部に永久磁石が設けられると共に外扉用下レール部に電磁装置が設けられ、外扉をスライドさせる際に、電磁装置により発生する磁力と永久磁石の磁力の反発力により外扉を浮上させるようにしたものである。
A power generation device according to the present invention is a power generation device in which an engine, a generator, and a control panel are installed inside an outer box, and the generator is driven by the engine to generate electric power, provided on a side surface of the outer box. It is slidable laterally by a roller mechanism , and includes an inner door on which a sound absorbing material is affixed, and an outer door provided outside the inner door and slidable laterally along the lower rail portion for the outer door, A permanent magnet is provided in the lower part of the outer door and an electromagnetic device is provided in the lower rail for the outer door. When the outer door is slid, the outer door is It is intended to rise.
本発明によれば、横方向にスライドする内扉と外扉を備え、外扉をスライドさせる際に、電磁装置により発生する磁力と永久磁石の磁力の反発力により外扉を浮上させるようにしたので、従来の外開き扉に比べて設置スペースが小さく、扉開放時の外気の影響による扉部品の破損が起こらず、且つ扉の開閉が容易な外箱を有する発電装置を得ることができる。 According to the present invention, the inner door and the outer door that slide in the lateral direction are provided, and when the outer door is slid, the outer door is lifted by the repulsive force of the magnetic force generated by the electromagnetic device and the magnetic force of the permanent magnet. Therefore, it is possible to obtain a power generation device having an outer box that has a smaller installation space than conventional doors that are open, that does not cause damage to door parts due to the influence of outside air when the door is opened, and that can be easily opened and closed.
実施の形態１．
以下に、本発明の実施の形態１に係る発電装置について、図面に基づいて説明する。図１は、本実施の形態１に係る発電装置の外箱を示す（ａ）平面図、（ｂ）側面図である。また、図２は、本実施の形態１に係る発電装置における外扉の下部の機構を説明する図である。なお、図中、同一、相当部分には同一符号を付している。
Embodiment 1 FIG.
Below, the electric power generating apparatus which concerns on Embodiment 1 of this invention is demonstrated based on drawing. FIG. 1A is a plan view and FIG. 1B is a side view showing an outer case of the power generator according to the first embodiment. Moreover, FIG. 2 is a figure explaining the mechanism of the lower part of the outer door in the electric power generating apparatus which concerns on this Embodiment 1. FIG. In the drawing, the same and corresponding parts are denoted by the same reference numerals.
本実施の形態１に係る発電装置１は、外箱２の内部にエンジン、発電機、および制御盤（いずれも図示省略）が設置され、エンジンにより発電機を駆動して電力を発生する。エンジンは、重油、灯油、軽油等のエネルギー源により稼動され、エンジンに直結された発電機は、エンジンの回転エネルギーを電気エネルギーに変換する。制御盤は、原動機および発電機の運転、停止、及び遮断機の開閉等を制御するとともに、負荷変動に対して回転数（周波数）、電圧を一定に保つ等の制御を行う。 In the power generation apparatus 1 according to the first embodiment, an engine, a generator, and a control panel (all not shown) are installed inside the outer box 2, and the generator is driven by the engine to generate electric power. The engine is operated by an energy source such as heavy oil, kerosene, or light oil, and a generator directly connected to the engine converts the rotational energy of the engine into electric energy. The control panel controls the operation and stop of the prime mover and the generator, the opening and closing of the circuit breaker, and the like, and performs control such as keeping the rotation speed (frequency) and voltage constant with respect to load fluctuations.
鋼板製の外箱２は、エンジンや発電機の騒音を減少させる防音（減音）の目的と、屋外設置の場合には雨水浸入防止の目的で設けられる。外箱２の１つの側面２ａには、点検用扉である内扉３と外扉５が設けられ、他の側面には点検用扉以外の例えば通気窓８が設けられる。ただし、扉や窓の数および配置は、図１に限定されるものではない。図１では、２組の内扉３と外扉５を設けているが、１組または３組以上であっても良い。 The outer casing 2 made of a steel plate is provided for the purpose of soundproofing (sound reduction) to reduce the noise of the engine and the generator, and for the purpose of preventing rainwater intrusion when installed outdoors. An inner door 3 and an outer door 5 that are inspection doors are provided on one side surface 2a of the outer box 2, and a ventilation window 8, for example, other than the inspection door is provided on the other side surface. However, the number and arrangement of doors and windows are not limited to those shown in FIG. In FIG. 1, although two sets of inner doors 3 and outer doors 5 are provided, one set or three or more sets may be used.
内扉３の下部には、内扉用レール部４に沿って内扉３を横方向にスライドさせるローラー機構（図示省略）が設けられる。また、内扉３には、防音のための吸音材が貼られる。この内扉３の外側に設けられた外扉５は、外扉用下レール部６に沿って横方向にスライドする。外扉５は、外扉用下レール部６と外扉用上レール部７によって挟持されている。ただし、外扉用下レール部６と外扉用上レール部７の間隔Ｈ１よりも、外扉５の縦方向の寸法Ｈ２を小さく設定し、所定の隙間を有するようにしている。 A roller mechanism (not shown) that slides the inner door 3 in the lateral direction along the inner door rail portion 4 is provided at the lower portion of the inner door 3. In addition, a sound absorbing material for soundproofing is affixed to the inner door 3. The outer door 5 provided on the outer side of the inner door 3 slides laterally along the outer door lower rail portion 6. The outer door 5 is sandwiched between an outer door lower rail portion 6 and an outer door upper rail portion 7. However, than the interval H 1 of the outer door for lower rail section 6 and the outer door on the rail unit 7, sets small longitudinal dimension of H 2 outer door 5, so that with a predetermined gap.
また、図２に示すように、外扉５の下部に永久磁石５１が設けられると共に、これに対向する外扉用下レール部６に電磁装置６１が設けられ、外扉５をスライドさせる際に、電磁装置６１により発生する磁力と永久磁石５１の磁力の反発力により外扉５を浮上させる。図１（ｂ）中、矢印Ａは、電源スイッチ１０が閉（オン）の時、電磁装置６１の電磁反発力により外扉５が浮上する方向を示している。 In addition, as shown in FIG. 2, a permanent magnet 51 is provided at the lower part of the outer door 5, and an electromagnetic device 61 is provided on the lower rail portion 6 for the outer door facing the outer door 5. The outer door 5 is lifted by the repulsive force of the magnetic force generated by the electromagnetic device 61 and the magnetic force of the permanent magnet 51. In FIG. 1B, an arrow A indicates a direction in which the outer door 5 is lifted by the electromagnetic repulsive force of the electromagnetic device 61 when the power switch 10 is closed (on).
電磁装置６１の電源は、発電装置１のエンジン始動用蓄電池と兼用の蓄電池９である。電磁装置６１の電源スイッチ１０は、外箱２の側面２ａに設置された外部スイッチ１１により開閉を制御される。 The power source of the electromagnetic device 61 is a storage battery 9 that also serves as an engine start storage battery of the power generation device 1. The power switch 10 of the electromagnetic device 61 is controlled to be opened and closed by an external switch 11 installed on the side surface 2 a of the outer box 2.
外扉５の下部の機構と電磁装置６１の動作ついて、図２および図３を用いて説明する。図２中、矢印Ｂは、永久磁石５１と電磁装置６１の電磁作用による反発力を示している。電源スイッチ１０を閉にすると、蓄電池９からの電流は銅線１２を介して電磁装置６１の本体を構成する鉄心６２に流れ、鉄心６２は電磁石となる。これにより、図３中、矢印Ｃで示す方向に電磁反発力が発生する。 The mechanism under the outer door 5 and the operation of the electromagnetic device 61 will be described with reference to FIGS. In FIG. 2, an arrow B indicates the repulsive force due to the electromagnetic action of the permanent magnet 51 and the electromagnetic device 61. When the power switch 10 is closed, the current from the storage battery 9 flows to the iron core 62 constituting the main body of the electromagnetic device 61 via the copper wire 12, and the iron core 62 becomes an electromagnet. As a result, an electromagnetic repulsive force is generated in the direction indicated by arrow C in FIG.
電磁装置６１の発生する磁力と、外扉５の下部に埋め込まれた永久磁石５１の磁力の反発力Ｂにより、外扉５は所定の距離ｘだけ浮上する。距離ｘは、図１に示す外扉用下レール部６と外扉用上レール部７の間隔Ｈ１と、外扉５の縦方向の寸法Ｈ２の差よりも小さくなるように設定される。これにより、浮上した外扉５が外扉５の上部と対向する外扉用上レール部７と接触せず、外扉５のスライドが容易になる。 Due to the magnetic force generated by the electromagnetic device 61 and the repulsive force B of the magnetic force of the permanent magnet 51 embedded in the lower part of the outer door 5, the outer door 5 floats by a predetermined distance x. The distance x is set to be smaller than the difference between the distance H 1 between the outer door lower rail portion 6 and the outer door upper rail portion 7 shown in FIG. 1 and the vertical dimension H 2 of the outer door 5. . Thereby, the floated outer door 5 does not contact the outer door upper rail portion 7 facing the upper portion of the outer door 5, and the outer door 5 can be easily slid.
一方、外扉５を固定させたい場合には、電源スイッチ１０を開にし、電磁装置６１を停止する。これにより、電磁作用による反発力Ｂが消滅して外扉５が外扉用下レール部６の上に乗り、その自重により固定される。なお、外扉５の下部と外扉用下レール部６に、滑りを良くするためのフッ素コーティング等のコーティングを施しても良い。 On the other hand, when the outer door 5 is desired to be fixed, the power switch 10 is opened and the electromagnetic device 61 is stopped. As a result, the repulsive force B due to electromagnetic action disappears, and the outer door 5 rides on the lower rail portion 6 for outer door and is fixed by its own weight. Note that the lower part of the outer door 5 and the lower rail part 6 for the outer door may be coated with a coating such as fluorine coating for improving slippage.
本実施の形態１の比較例として、従来の発電装置における外開き扉を図４に示す。従来の発電装置の外箱２０には、ヒンジ２１を支点に開閉する外開き扉２２が取り付けられ、点検時等には、図４中、Ｌで示すメンテナンススペースが必要であり、その分を見込んだ設置スペースが必要であった。また、点検時には、外開き扉２２は外側に開いた状態であるため、図４中、矢印Ｄで示す外気の流れを受け、ヒンジ２１や過開き防止ストッパー２３が破損することがあった。 As a comparative example of the first embodiment, an exterior door in a conventional power generator is shown in FIG. An outer opening door 22 that opens and closes with a hinge 21 as a fulcrum is attached to the outer case 20 of the conventional power generator. A maintenance space indicated by L in FIG. It needed installation space. Further, at the time of inspection, since the outer opening door 22 is in a state of being opened to the outside, the hinge 21 and the over-opening prevention stopper 23 may be damaged due to the flow of outside air indicated by the arrow D in FIG.
このような従来の外開き扉２２の持つ課題に対し、本実施の形態１では、内扉３と外扉５を横方向にスライドするので、発電装置１周囲のメンテナンススペースを最小化することができる。また、内扉３は、スライドが容易なローラー機構を備えており、外扉５により外部と遮断されているため、ローラー機構への異物の噛み込みや外部環境による劣化が殆ど無い。さらに、内扉３に吸音材を貼ることにより、発電装置１の扉部の防音性能を確保することができる。 In the first embodiment, the inner door 3 and the outer door 5 are slid in the lateral direction, so that the maintenance space around the power generator 1 can be minimized. it can. Further, the inner door 3 includes a roller mechanism that can be easily slid, and is blocked from the outside by the outer door 5, so that there is almost no deterioration due to the biting of foreign matter into the roller mechanism and the external environment. Furthermore, the soundproofing performance of the door portion of the power generation device 1 can be ensured by attaching a sound absorbing material to the inner door 3.
また、外扉５をスライドさせる際に、電磁反発力により外扉５を浮上させるようにしたので、外扉５のスライドが容易であり、保守点検時に扉のスライドに要する労力が低減される。また、外扉５には、ローラー機構等の機械的回転動作部がないため、異物噛み込み等による故障の可能性が低い。 Further, when the outer door 5 is slid, the outer door 5 is lifted by an electromagnetic repulsive force, so that the outer door 5 can be easily slid, and labor required for sliding the door during maintenance inspection is reduced. Further, since the outer door 5 does not have a mechanical rotation operation unit such as a roller mechanism, the possibility of failure due to foreign object biting is low.
以上のように、本実施の形態１によれば、従来の外開き扉２２に比べて設置スペースが小さく、扉開放時の外気の影響による扉部品の破損が起こらず、且つ扉の開閉が容易な外箱２を有する発電装置１を得ることができる。なお、本発明は、その発明の範囲内において、実施の形態を適宜、変形、省略することが可能である。 As described above, according to the first embodiment, the installation space is smaller than that of the conventional outer opening door 22, the door parts are not damaged due to the outside air when the door is opened, and the door can be easily opened and closed. The power generator 1 having the outer casing 2 can be obtained. In the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.
