【従来の技術】[Prior art]

近年、深海用機器、潜水調査船、潜水作業ロボット等は、潜水深度の深化、潜 水時間の長期間化によってその主動力電源用電池の大容量化の要求が高まり、ま た搭載される計器類、通信機器類の多様化によってその非常用電源としての電池 の大容量化の要求が高まってきている。 In recent years, deep sea equipment, diving research vessels, diving work robots, etc. have been required to have large capacity batteries for main power supply due to deeper diving depths and longer diving times, and the instruments installed Due to the diversification of communication equipment and communication equipment, there is an increasing demand for larger capacity batteries as emergency power sources.

【0003】 上記のような電池は、深海用機器等に搭載される機器類の総排水量の10〜3 0%を占めるため、耐圧殻の外部に設けた電池収納槽内に装備されている。The battery as described above occupies 10 to 30% of the total amount of drainage of equipment mounted in deep-sea equipment and the like, and is therefore provided in a battery storage tank provided outside the pressure-resistant shell.

【0004】 そして、このような電池収納槽には、電気絶縁油を内蔵した耐油性、耐海水性 ホースまたはゴム袋からなる伸縮袋均圧装置が取り付けられ、深海における水圧 によって前記伸縮袋均圧装置内に残留する気体が圧縮されると、前記耐油性、耐 海水性ホースまたはゴム袋が圧縮され、それによって電気絶縁油が電池収納槽内 に注入されて電池収納槽の内外の圧力差がなくなるようになっている。In addition, an elastic bag pressure equalizing device including an oil-resistant, seawater-resistant hose or a rubber bag containing electric insulating oil is attached to such a battery storage tank, and the elastic bag pressure equalizing device is installed by the water pressure in the deep sea. When the gas remaining in the device is compressed, the oil-resistant, seawater-resistant hose or rubber bag is compressed, and as a result, the electric insulating oil is injected into the battery storage tank and the pressure difference between the inside and outside of the battery storage tank is reduced. It's gone.

【0005】 上記した構成からなる油漬型電池の従来例を図4および図5により説明する。A conventional example of the oil-immersed battery having the above structure will be described with reference to FIGS. 4 and 5.

【0006】 図4および図5に示した油漬型電池は、内部に複数の単電池10が収納され、 その上部は蓋9によって密閉されるとともにその底部または側部の隔壁4に通油 孔3が設けられた電池収納槽1と、前記電池収納槽1の底部または側部に取り付 けられた伸縮袋均圧装置2とからなり、内外の圧力差に応じて伸縮袋均圧装置2 のカバー6に設けられた海水流通孔18から海水が流入し、その圧力によって伸 縮袋均圧装置2から電気絶縁油が通油孔3を通って電池収納槽1内に流入し、電 池収納槽1の内外の圧力差が補償されるように構成されてなる。The oil-immersed battery shown in FIGS. 4 and 5 has a plurality of cells 10 housed therein, the upper part of which is sealed by a lid 9 and the oil holes 3 in the partition walls 4 at the bottom or sides thereof. And a stretchable bag pressure equalizing device 2 attached to the bottom or side of the battery storage chamber 1. Seawater flows in from the seawater circulation hole 18 provided in the cover 6, and the pressure causes the electric insulating oil from the expansion bag pressure equalizer 2 to flow into the battery storage tank 1 through the oil passage hole 3 to store the battery. The pressure difference between the inside and the outside of the tank 1 is compensated.

【0007】 なお、図4および図5において、5は伸縮袋均圧装置2のフランジ部、7は伸 縮袋均圧装置2のカバー6に設けられたフランジ部、8はカバー6と電池収納槽 1とを結合するためのボルトである。In FIGS. 4 and 5, 5 is a flange portion of the expansion bag equalizing device 2, 7 is a flange portion provided on the cover 6 of the expansion bag equalizing device 2, and 8 is the cover 6 and the battery housing. It is a bolt for connecting with the tank 1.

【0008】[0008]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記した従来の油漬型電池では、電池の大容量化に伴って伸縮袋均圧装置2も 大きくする必要があり、そのためカバー6が大型化し、電池の重量や電池の占有 空間が増大するという問題があった。 In the conventional oil-immersed battery described above, it is necessary to increase the size of the expansion bag equalizer 2 as the battery capacity increases, which causes the cover 6 to increase in size and increase the battery weight and the space occupied by the battery. was there.

【0009】 また、カバー6と電池収納槽1とを気密かつ液密に結合することが困難になり 、信頼性の高い大容量の油漬型電池が得られないという問題があった。Further, it becomes difficult to airtightly and liquid-tightly connect the cover 6 and the battery storage tank 1, and there is a problem that a highly reliable large-capacity oil-immersed battery cannot be obtained.

【0010】 また、上記した従来の油漬型電池では、深海用機器、潜水調査船、潜水作業ロ ボット等の深度を急速に変化させた場合、カバー6に設けられた海水流通穴18 から流入または流出する海水の圧力の変化に伸縮袋均圧装置2が追従できず、電 池収納槽1の内外の圧力差の補償を適正に行うことができないという問題があっ た。In addition, in the above conventional oil-immersed battery, when the depth of deep-sea equipment, diving research ship, diving work robot, etc. is rapidly changed, inflow or discharge from the seawater circulation hole 18 provided in the cover 6 is performed. There was a problem that the expansion bag equalizer 2 could not follow the change in the pressure of the outflowing seawater, and the pressure difference between the inside and outside of the battery storage tank 1 could not be properly compensated.

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を解決するため、本考案は、電池収納槽内に収納された単電池または 単電池群と、前記電池収納槽内の空間および単電池間の空間に満たされた電気絶 縁油とを有してなる油漬型電池において、前記電池収納槽の下部に電気絶縁油通 油口を設け、この電気絶縁油通油口に、電気絶縁油が封入され、一部の直径が前 記電気絶縁油通油口の直径より大きい柔軟性の太径ホース部を有する耐油性、耐 海水性ホースが着脱自在に取り付けられる構成とし、かつ前記太径ホース部の、 電気絶縁油通油口から遠い部分における水圧による変形度合が電気絶縁油通油口 から近い部分における水圧による変形度合より大きくなるようにし、前記電気絶 縁油が電池収納槽と前記耐油性、耐海水性ホースとの間を移動することによって 電池収納槽の内外の圧力差が補償されることを特徴とするものである。 In order to solve the above problems, the present invention provides a cell or a group of cells stored in a battery storage tank, and an electric insulation oil filled in the space in the battery storage tank and the space between the single cells. In the oil-immersed battery that has, an electrically insulating oil passage port is provided in the lower part of the battery storage tank, and the electrically insulating oil passage port is filled with electrically insulating oil. An oil-resistant, seawater-resistant hose having a flexible large-diameter hose that is larger than the diameter of the oil passage is detachably attached, and the large-diameter hose is far from the electrically insulating oil passage. So that the degree of deformation due to water pressure is greater than the degree of deformation due to water pressure in the portion near the electric insulating oil passage, and the electric insulation oil moves between the battery storage tank and the oil resistant seawater resistant hose. By the inside of the battery storage tank Pressure difference is characterized in being compensated.

【作 用】[Work]

従って、本考案は、柔軟性を有する耐油性、耐海水性ホースに深海における水 圧を補償するための電気絶縁油を封入しているから、電池の重量の増大を防止す ることができ、しかも前記ホースは深海用機器、潜水調査船、潜水作業ロボット 等に搭載される機器類の間隙に収容することができるので、電池の占有空間の増 大を防止することができる。 Therefore, according to the present invention, since the electrically insulating oil for compensating the water pressure in the deep sea is filled in the flexible oil resistant and sea water resistant hose, it is possible to prevent the increase in the weight of the battery. Moreover, since the hose can be housed in the space between the equipment mounted on the equipment for deep sea, the diving research ship, the diving work robot, etc., it is possible to prevent the occupied space of the battery from increasing.

【0013】 また、前記耐油性、耐海水性ホースは、電池収納槽の電気絶縁油通油口に着脱 自在に取り付けられる構成としているから、取り付け部分の気密性、液密性を向 上させることができ、油漬型電池の信頼性を向上させることができる。Further, since the oil resistant and sea water resistant hose is configured to be detachably attached to the electrically insulating oil passage of the battery storage tank, the airtightness and liquid tightness of the attached portion should be improved. Therefore, the reliability of the oil-immersed battery can be improved.

【0014】 また、前記耐油性、耐海水性ホースに、直径が電気絶縁油通油口の直径より大 きい太径ホース部を設けたことにより、この太径ホース部内に多量の電気絶縁油 を封入することができ、しかもその肉厚を電気絶縁油通油口側で大きくするか、 その直径を電気絶縁油通油口側で小さくすることにより、水圧による太径ホース 部の変形が円滑になり、深海用機器等の深度を急速に変化させても、海水の圧力 の変化に即時に追従させて電池収納槽の内外の圧力差を補償することができる。In addition, since the oil-resistant and seawater-resistant hose is provided with a large-diameter hose portion having a diameter larger than the diameter of the electrically-insulating oil passage, a large amount of electrically-insulating oil can be stored in the large-diameter hose portion. It can be sealed, and the thickness of the hose can be increased on the side of the electrical insulating oil passage or reduced on the side of the electrical insulating oil passage to ensure smooth deformation of the large-diameter hose due to water pressure. Therefore, even if the depth of deep-sea equipment is rapidly changed, the pressure difference between the inside and outside of the battery storage tank can be compensated by immediately following the change in seawater pressure.

【実施例】【Example】

図1は、本考案の油漬型電池の第1の実施例を示すもので、電池収納槽1の下 部に電気絶縁油通油口11を設け、この電気絶縁油通油口11に電気絶縁油13 を封入した柔軟性を有する耐油性、耐海水性ホース12の一端が着脱自在に取り 付けられるようにし、取り付けることによって前記一端に有する閉止栓カプラが 開放し、取り外すことによって前記閉止栓カプラが閉塞するようになっている。 FIG. 1 shows a first embodiment of the oil-immersed battery according to the present invention, in which an electrically insulating oil passage 11 is provided at the bottom of the battery storage tank 1, and the electrically insulating oil passage 11 is electrically insulated. One end of a flexible oil-resistant and seawater-resistant hose 12 containing oil 13 is detachably attached, and by attaching it, the closing plug coupler at the one end is opened, and by removing the closing plug coupler. Is blocked.

【0016】 そして、前記耐油性、耐海水性ホース12の一部には太径ホース部16が設け られ、前記太径ホース部16の肉厚は電気絶縁油通油口11側を大きくし、電気 絶縁油通油口11から遠くなるにつれて小さくなるようにしている。A large-diameter hose portion 16 is provided in a part of the oil-resistant and seawater-resistant hose 12, and the thickness of the large-diameter hose portion 16 is increased on the side of the electric insulating oil passage 11 and It becomes smaller as the distance from the electrical insulating oil passage 11 increases.

【0017】 なお、図1において、14は前記耐油性、耐海水性ホース12の他端を封止す る封止栓、15は前記封止栓14によって前記耐油性、耐海水性ホース12を確 実に封止するための封止バンドである。In FIG. 1, 14 is a sealing plug for sealing the other end of the oil-resistant, seawater-resistant hose 12, and 15 is the oil-proof, seawater-resistant hose 12 by the sealing plug 14. It is a sealing band for reliable sealing.

【0018】 上記した油漬型電池は、深海中で耐油性、耐海水性ホース12の太径ホース部 16が水圧を受け、それによって封入された電気絶縁油13が電気絶縁油通油口 11を経て電池収納槽1内に流れ込み、電池収納槽1内に残留する気体が圧縮さ れるため、槽の内外の圧力差が補償されることになる。この時、前記電池収納槽 1内の単電池10は前記圧縮力を受けるだけで、深海中の水圧の直接の影響を受 けて破壊することはない。In the oil-immersed battery described above, the large-diameter hose portion 16 of the oil-resistant and seawater-resistant hose 12 is subjected to water pressure in the deep sea, and the electric insulating oil 13 enclosed thereby causes the electric insulating oil passage 11 to pass through. After that, the gas that flows into the battery storage tank 1 and remains in the battery storage tank 1 is compressed, so that the pressure difference between the inside and outside of the tank is compensated. At this time, the unit cell 10 in the battery storage tank 1 only receives the compressive force and is not destroyed by being directly affected by the water pressure in the deep sea.

【0019】 そして、前記太径ホース部16肉厚は、電気絶縁油通油口11側を大きくし、 電気絶縁油通油口11から遠くなるにつれて小さくなるようにしているから、深 海中で太径ホース部16が受ける水圧が急変しても、その変化を肉厚の小さい部 分で即時に検知することができる。The wall thickness of the large-diameter hose portion 16 is increased on the side of the electrically insulating oil passage 11 and becomes smaller as the distance from the electrically insulating oil passage 11 increases. Even if the water pressure received by the radial hose portion 16 suddenly changes, the change can be immediately detected by the portion having a small wall thickness.

【0020】 図2は、本考案の油漬型電池の第2の実施例を示すもので、耐油性、耐海水性 ホース12の一部に太径ホース部16が設けられ、その直径は電気絶縁油通油口 11側を小さくし、電気絶縁油通油口11側から遠くなるにつれて大きくなるよ うにしたもので、他の構成は図1のものと同じである。FIG. 2 shows a second embodiment of the oil-immersed battery according to the present invention, in which a large-diameter hose portion 16 is provided in a part of the oil-resistant and seawater-resistant hose 12, the diameter of which is electrically insulated. The oil passage port 11 side is made smaller and becomes larger as it gets farther from the electrically insulating oil passage port 11 side, and other configurations are the same as those in FIG.

【0021】 上記した第2の実施例では、太径ホース部16の直径は、電気絶縁油通油口1 1から遠くなるにつれて大きくなるようにしているから、深海中で太径ホース部 16が受ける水圧は電気絶縁油通油口11から遠くなるにつれて大きくなり、そ の部分の変化を即時に検知することができる。In the above-described second embodiment, the diameter of the large-diameter hose portion 16 is set to increase as the distance from the electrically insulating oil passage 11 increases. The received water pressure increases as the distance from the electrically insulating oil passage 11 increases, and a change in that portion can be immediately detected.

【0022】 上記した各実施例では、耐油性、耐海水性ホース12の一部に設けた太径ホー ス部16は耐油性、耐海水性ホース12と気密かつ液密に接続するようにしても よいことは言うまでもない。In each of the above-described embodiments, the large diameter hose portion 16 provided in a part of the oil resistant seawater resistant hose 12 is connected to the oil resistant seawater resistant hose 12 in an airtight and liquidtight manner. It goes without saying that it is good.

【0023】 図3は、本考案の油漬型電池の第3の実施例を示すもので、耐油性、耐海水性 ホース12の一部に設けた太径ホース部16を垂直に配置し、上部が電気絶縁油 通油口11に取り付けられるようにし、太径ホース部16の下部で受ける水圧が 大きくなるようにし、水圧の変化を即時に検知できるようにしたものである。FIG. 3 shows a third embodiment of the oil-immersed battery of the present invention, in which a large-diameter hose portion 16 provided in a part of the oil-resistant and seawater-resistant hose 12 is vertically arranged and Is attached to the electrically insulating oil passage 11 so that the water pressure received at the lower portion of the large-diameter hose portion 16 becomes large so that a change in water pressure can be immediately detected.
