Abstract
Description
主として潜水作業に用いる電池収納ケースにおいて、内部に収納した電池により発生したガスを放出する防爆構造に関する技術であって、具体的には、新規な電池収納部圧抜シール構造を提供するものである。 In a battery storage case mainly used for diving work, it is a technology related to an explosion-proof structure that releases gas generated by a battery stored inside, and specifically provides a novel battery storage part pressure-release seal structure. .
潜水作業に用いる電源としての電池の収納部は、外部からの水圧に対して、水深１００〜３００ｍの外部からの圧力、１〜３ＭＰａに耐える構造とすることが一般的である。しかるに、屋外で使用する機器であることから特に電池の交換の時に電池が濡れることがある。本発明は、この外部から圧力のかかる電池収納部の耐圧構造において、内部の電池が水に濡れたときの電池周辺の電気分解によって生じるガスによる内部圧力の放出構造に関わる技術である。 A battery storage unit as a power source used for diving work generally has a structure capable of withstanding an external pressure of 1 to 3 MPa at a water depth of 100 to 300 m against an external water pressure. However, since the device is used outdoors, the battery may get wet particularly when the battery is replaced. The present invention is a technique related to a structure for releasing internal pressure by gas generated by electrolysis around the battery when the internal battery gets wet with water in the pressure-resistant structure of the battery housing portion under pressure from the outside.
この現象が起きた時に、電池収納部内の圧力が上昇すると、電池の蓋を開けたときにこの蓋が内部の圧力で飛び、操作者が怪我をする可能性があった。このため、設計によって要求される内部の圧力上昇限度は異なるが、０．０５〜０．５ＭＰａにすることが望ましい。 When this phenomenon occurs, if the pressure in the battery compartment rises, when the battery lid is opened, the lid may fly due to the internal pressure, and the operator may be injured. For this reason, although the internal pressure rise limit requested | required by design differs, it is desirable to set it as 0.05-0.5 Mpa.
この電池収納部の内部に溜まったガスの外部への放出を目的として、従来技術では、圧抜きバルブを取りつけるが、小さな場所に取りつける目的で、破損して再使用できない構造であったり、専用の取りつけ場所を確保しなければならない欠点があった。 For the purpose of releasing the gas accumulated inside the battery compartment to the outside, the conventional technology installs a pressure relief valve, but it is designed to be installed in a small place and cannot be reused. There was a drawback of having to secure a mounting location.
上記の特許文献は、電池収納部の内部の圧力上昇に対する防爆構造でしかも限られた場所に取りつける構造が提案されているが、欠点としては、圧抜き部が破損して再使用できない構造であった。
尚、他の圧抜き構造としていわゆる逆止弁があるが、これには専用の取りつけ場所を確保しなければならないという構造上の欠陥があり、通常では採用はできない。
In the above patent document, an explosion-proof structure against pressure rise inside the battery housing part and a structure that can be mounted in a limited place have been proposed. However, the disadvantage is that the pressure relief part is damaged and cannot be reused. It was.
In addition, there is a so-called check valve as another pressure release structure, but this has a structural defect that a dedicated mounting location must be secured, and cannot be normally employed.
本発明は、以上のような従来技術の欠点を改良しようとするものであり、電池の電気分解で発生するガスを、耐圧密閉構造である電池収納部から、単純で、しかも小さな取りつけ場所で外部に放出する圧抜構造を提供することを目的とする。 The present invention is intended to improve the above-described drawbacks of the prior art, and gas generated by the electrolysis of the battery is externally removed from the battery housing portion having a pressure-resistant sealed structure in a simple and small mounting place. An object of the present invention is to provide a pressure relief structure that discharges to the surface.
本発明の要旨は、電池収納部圧抜シール構造に関するものであり、水中にて用いる機器の電池収納部外殻に対し、一定間隔をもって支持される外蓋を配置し、前記電池収納部外殻に前記外蓋に対向して溝部を形成すると共に、当該溝部に沿ってＵ字状弾性体を内蔵させ、かかるＵ字状弾性体の足部先端が溝部の底面及び外蓋面に弾発力を持って接し、かつ当該Ｕ字状弾性体の開口部側を周囲の空間と繋がる隙間方向に配置したことを特徴とする。 The gist of the present invention relates to a battery housing part pressure-release seal structure, and an outer lid that is supported at a predetermined interval is disposed with respect to a battery housing part outer shell of a device used in water, and the battery housing part outer shell. A groove portion is formed opposite to the outer lid, and a U-shaped elastic body is incorporated along the groove portion, and the tip of the foot portion of the U-shaped elastic body is elastically applied to the bottom surface of the groove portion and the outer lid surface. And the opening side of the U-shaped elastic body is arranged in the gap direction connecting to the surrounding space.
そして、より具体的には、前記電池収納部外殻の開口部を囲んで溝部を形成したもので、この溝部の断面構造が四角形状であり、更に、前記Ｕ字形状弾性体の足部にあって、溝部の底面に接する側の足部の長さが外蓋面に接する側の足部の長さより長い電池収納部圧抜シール構造に係るものである。 More specifically, a groove is formed surrounding the opening of the battery housing outer shell, and the cross-sectional structure of the groove is a square shape. In this case, the length of the foot portion on the side in contact with the bottom surface of the groove portion is longer than the length of the foot portion on the side in contact with the outer lid surface.
本発明にあって、電池収納部が水中に沈められると、水圧、即ち外部側隙間から周囲の圧力が上昇し、Ｕ字形状の弾性体のＵの開口部に水圧が加わる。このため、前記弾性体は両足先端部が溝の底部と外蓋に弾性力で押しつけられるので、水が内部に浸入することはない。このように、弾性体におけるＵ字内側からの圧力が発生し、セルフシールの機能が発揮されることとなる。 In the present invention, when the battery housing part is submerged in water, the water pressure, that is, the surrounding pressure rises from the external gap, and the water pressure is applied to the U opening of the U-shaped elastic body. For this reason, since the elastic body is pressed against the bottom of the groove and the outer lid by the elastic force at the front ends of both legs, water does not enter the inside. In this way, pressure from the inside of the U-shape in the elastic body is generated, and the self-sealing function is exhibited.
一方、電池が濡れた場合、特に海水の場合は海水中に電解質を含むので、塩素と水素が気体となって多量に発生する。この結果、内部の圧力が周囲の圧力より高い状態となる。しかるに、Ｕ形状の弾性体は内部側隙間からのこの圧力により、足先先端部が狭まるように変形する。その結果、気体の流路が発生し気体が外部(海水中)に逃出する。このように、気体を外部へ逃出した後は内部の圧力が低下し、再び元の状態に戻ることとなる。このように、本発明の電池収納部圧抜シール構造は破損が発生しない構造となるのである。 On the other hand, when the battery is wet, especially in the case of seawater, since the seawater contains an electrolyte, chlorine and hydrogen are generated in a large amount as gas. As a result, the internal pressure is higher than the ambient pressure. However, the U-shaped elastic body is deformed so that the tip of the foot tip is narrowed by this pressure from the internal gap. As a result, a gas flow path is generated and the gas escapes outside (in the seawater). As described above, after the gas escapes to the outside, the internal pressure decreases and the original state is restored. Thus, the battery housing part pressure-release seal structure of the present invention has a structure in which damage does not occur.
以下、本発明の電池収納部圧抜シール構造の具体例を示すが、本発明はこれらに限定されるものではないことは勿論である。 Hereinafter, although the specific example of the battery accommodating part pressure-release seal structure of this invention is shown, of course, this invention is not limited to these.
以下、具体例をもって本発明の電池収納部圧抜シール構造を説明するが、図１は本発明の第１実施例の一部省略断面図であり、図２は図１の主要部の拡大断面図である。図中、符号１は水中ライト等の機器を示したもので、この例では、説明を簡略化するために電池収納具そのものを示している。符号２は電池収納部であって、この収納部２内に筒型電池３が納められている。 1 is a partially omitted sectional view of the first embodiment of the present invention, and FIG. 2 is an enlarged sectional view of the main part of FIG. FIG. In the figure, reference numeral 1 denotes a device such as an underwater light, and in this example, the battery housing itself is shown to simplify the description. Reference numeral 2 denotes a battery housing portion in which a cylindrical battery 3 is housed.
さて、かかる電池３に対して電池収納部２の開口部４に対して外蓋５が螺着されている。即ち、機器１の電池収納部２の外殻６に対し、一定間隔（ｄ）をもって支持される外蓋５を配置する。そして、この外殻６には外蓋５に対向する部位に好ましくは断面四角形状の周溝部７を形成すると共に、当該溝部７に沿って図３に例示したごときＵ字状弾性体８を内蔵させ、かかるＵ字状弾性体８の足部先端８Ａ及び８Ｂが溝部７の底面７Ａ及び外蓋５の内面５Ａに弾発力を持って接し、かつ当該Ｕ字状弾性体８の開口部８Ｃ側を周囲の空間(即ち水中側)と繋がる側に向けて配置したことを特徴とするものである。 Now, the outer lid 5 is screwed to the opening 4 of the battery housing 2 with respect to the battery 3. In other words, the outer lid 5 that is supported at a constant interval (d) is disposed on the outer shell 6 of the battery storage unit 2 of the device 1. The outer shell 6 is formed with a circumferential groove portion 7 preferably having a quadrangular cross section at a portion facing the outer lid 5, and a U-shaped elastic body 8 as shown in FIG. The foot tips 8A and 8B of the U-shaped elastic body 8 are elastically in contact with the bottom surface 7A of the groove 7 and the inner surface 5A of the outer lid 5, and the opening 8C of the U-shaped elastic body 8 is used. The side is arranged toward the side connected to the surrounding space (that is, the underwater side).
そして、より具体的には、前記Ｕ字形状弾性体８の足部８Ａ、８Ｂにあって、溝部７の底面７Ａに接する側の足部８Ａの長さが、外蓋５の内面５Ａに接する側の足部８Ｂの長さより長い構造とするのが好ましい。 More specifically, the length of the foot portion 8A on the side of the foot portion 8A, 8B of the U-shaped elastic body 8 that contacts the bottom surface 7A of the groove portion 7 is in contact with the inner surface 5A of the outer lid 5. It is preferable to make the structure longer than the length of the foot 8B on the side.
図４は図２における水中に没した際の圧力がかかる状態図である。即ち、機器（電池収納具）１が水中に沈められると、水圧、即ち外部側隙間（ｄ）から水が入り込み、Ｕ字形状の弾性体８のＵ形状の開口部８Ｃに水圧が加わる。このため、前記弾性体８は両足部８Ａ、８Ｂが夫々溝部７の底部７Ａと外蓋５の内面５Ａに弾性力で押しつけられることになり、水が機器１の内部に侵入することはない。この状態を矢印で示した。このように、弾性体８におけるＵ形状の開口部８Ｃ側からの圧力が発生し、セルフシールの機能が発揮されることとなる。 FIG. 4 is a state diagram in which pressure is applied when submerged in water in FIG. That is, when the device (battery storage device) 1 is submerged in water, water enters the water pressure, that is, the external gap (d), and water pressure is applied to the U-shaped opening 8C of the U-shaped elastic body 8. For this reason, in the elastic body 8, both foot portions 8 </ b> A and 8 </ b> B are pressed against the bottom portion 7 </ b> A of the groove portion 7 and the inner surface 5 </ b> A of the outer lid 5, and water does not enter the inside of the device 1. This state is indicated by an arrow. Thus, the pressure from the U-shaped opening 8C side in the elastic body 8 is generated, and the self-sealing function is exhibited.
更に詳しくは、水圧によってＵ字形状弾性体８は図２に示すように四角形状の溝部７の左側の側面に押しつけられ、その水圧によってＵ字形状弾性体８隙間（ｄ）を塞ぎ続けて、水圧による水の侵入を防止する。 More specifically, the U-shaped elastic body 8 is pressed against the left side surface of the rectangular groove portion 7 as shown in FIG. 2 by water pressure, and the U-shaped elastic body 8 gap (d) is continuously closed by the water pressure, Prevent water intrusion due to water pressure.
一般のＯリングに用いられるゴム硬度７０度の弾性体にて形成されたＵ字形状弾性体８を用い、隙間（ｄ）を０．３ｍｍ以下とすれば、３００ｍ相当の水圧３ＭＰａで隙間（ｄ）へのはみ出し現象で破損しないことを確認した。 If a U-shaped elastic body 8 formed of an elastic body having a rubber hardness of 70 degrees used for general O-rings is used and the gap (d) is 0.3 mm or less, the gap (d It was confirmed that it did not break due to the protrusion phenomenon to).
一方、電池３が水に濡れた場合、特に海水の場合は塩素と水素が気体となって多量に発生し、電池収納部２内に充満する。この結果、電池収納部２内の圧力がより高い状態となり、通常の場合には電池収納具１が破壊される可能性が高くなる。しかるに、図５は図２における内部から気体が抜ける際の状態図であり、本発明の電池収納部圧抜シール構造にあっては、電池収納部２内にて発生した気体が隙間（ｄ）を通ってＵ形状の弾性体８に達し、内側からのかかる気体の圧力により、両足部８Ａ，８Ｂ(特に足部８Ｂ側)が接触している夫々の面より離れるように変形する。この状態を矢印で示した。その結果、気体の流路が発生し気体が外部(海水中)に逃出する。このように、気体を外部へ逃出した後は電池収納部２の内部の圧力が低下し、再び元の状態に戻ることとなる。このように、本発明の電池収納部圧抜シール構造は内部にて気体の発生があっても破損が生じない構造となるのである。 On the other hand, when the battery 3 gets wet with water, especially in the case of seawater, chlorine and hydrogen are generated in a large amount as gas and fill the battery storage unit 2. As a result, the pressure in the battery storage unit 2 becomes higher, and there is a high possibility that the battery storage device 1 is destroyed in a normal case. However, FIG. 5 is a state diagram when the gas escapes from the inside in FIG. 2, and in the battery housing part pressure-release seal structure of the present invention, the gas generated in the battery housing part 2 is a gap (d). It passes through the U-shaped elastic body 8 and is deformed so as to be separated from the respective surfaces where both foot portions 8A and 8B (particularly on the foot portion 8B side) are in contact with each other by the pressure of the gas from the inside. This state is indicated by an arrow. As a result, a gas flow path is generated and the gas escapes outside (in the seawater). As described above, after the gas escapes to the outside, the pressure inside the battery housing portion 2 decreases and returns to the original state. As described above, the battery housing part pressure-release seal structure of the present invention has a structure in which no damage occurs even if gas is generated inside.
一般のＯリングに用いられるゴム硬度７０度の弾性体にて形成されたＵ字形状弾性体８を用い、足部８Ａ、８Ｂの寸法を巾０．５ｍｍ、長さ１．０ｍｍとし、足先端の取りつけ時の変形量を０．１〜０．５ｍｍとしたところ、気体の流出開始圧力は０．０５〜０．２ＭＰａとなった。この結果から、巾２ｍｍ以下で高さ２ｍｍ以下の小さな四角形状溝部寸法での圧抜き構造が可能であることを確認した。 Using a U-shaped elastic body 8 formed of an elastic body with a rubber hardness of 70 degrees used for general O-rings, the dimensions of the foot portions 8A and 8B are 0.5 mm wide and 1.0 mm long, and the tip of the foot When the amount of deformation at the time of mounting was set to 0.1 to 0.5 mm, the gas outflow start pressure was 0.05 to 0.2 MPa. From this result, it was confirmed that a pressure relief structure with a small rectangular groove having a width of 2 mm or less and a height of 2 mm or less was possible.
図６は本発明の第２実施例の一部省略断面図である。即ち、この例ではいわゆるボタン電池３が用いられた機器１に対する例であり、電池収納部２内にボタン電池３が納められている。かかる電池３に対して電池収納部２には丸型の開口部４が形成されており、この例では、開口部４の外殻６の側面に対して外蓋５が爪５Ｂをもって嵌め合わされている。即ち、機器１の電池収納部２の外殻６に対し、一定間隔（ｄ）をもって支持される外蓋５を配置したものである。そして、この外殻６の頂面には外蓋５に対向して断面四角形状の周溝部７を形成すると共に、当該溝部７にＵ字状弾性体８を内蔵させ、かかるＵ字状弾性体８の足部先端８Ａ及び８Ｂが溝部７の底面７Ａ及び外蓋５の内面５Ａに弾発力を持って接し、かつ当該Ｕ字状弾性体８の開口部８Ｃ側を周囲の空間(即ち水中側)と繋がる側に向けて配置したことを特徴とするものである。 FIG. 6 is a partially omitted sectional view of the second embodiment of the present invention. In other words, this example is an example of a device 1 using a so-called button battery 3, and the button battery 3 is housed in the battery housing 2. A round opening 4 is formed in the battery housing portion 2 with respect to the battery 3. In this example, an outer lid 5 is fitted to the side surface of the outer shell 6 of the opening 4 with claws 5B. Yes. In other words, the outer lid 5 that is supported at a constant interval (d) is disposed with respect to the outer shell 6 of the battery housing portion 2 of the device 1. A peripheral groove portion 7 having a quadrangular cross section is formed on the top surface of the outer shell 6 so as to face the outer lid 5, and a U-shaped elastic body 8 is built in the groove portion 7. 8 end portions 8A and 8B of the groove portion 7 are in contact with the bottom surface 7A of the groove portion 7 and the inner surface 5A of the outer lid 5 with elasticity, and the opening 8C side of the U-shaped elastic body 8 is surrounded by the surrounding space (ie underwater). It is characterized by being arranged toward the side connected to the side).
前記Ｕ字形状弾性体８の挙動は実施例１と同様であるので説明は省略するが、水中にあってはセルフシールの機能が発揮され、内部にて気体の発生があっても破損が生じない構造となる。 Since the behavior of the U-shaped elastic body 8 is the same as that of the first embodiment, a description thereof will be omitted. However, the self-sealing function is exhibited in water, and even if gas is generated inside, the U-shaped elastic body 8 is damaged. No structure.
ボタン電池に実施した実施例は、取りつけ時の内部の圧力上昇を極力抑えた例である。即ち、外蓋５を締めたときのシール開始から取りつけ完了までの内部の容積変化が小さいことと、内部の圧力を外部に放出しやすいことから、組立時の内部の圧力が上昇しにくい構造となる。圧力センサー等圧力の影響を受けやすい機器を電池と共に組み込みする目的の構造に適した実施例である。 The embodiment implemented in the button battery is an example in which the internal pressure rise during installation is suppressed as much as possible. That is, since the internal volume change from the start of sealing to the completion of mounting when the outer lid 5 is tightened is small and the internal pressure is easily released to the outside, the internal pressure during assembly is difficult to increase. Become. This is an embodiment suitable for a structure intended to incorporate a device such as a pressure sensor, which is susceptible to pressure, together with a battery.
以上の実施例からも分かるように、特にＵ字状弾性体の外蓋に接する側の足部厚さを薄くすること、及び外蓋側の足部先端の取りつけ時の変形量を反対側より小さくすることにより、かかる弾性体足部の動作開始圧力が溝部側の弾性体足部の動作開始圧力より小さくなり、安定した気体流出を可能とすることができる。更に、弾性体の足部長さを四角形状溝側部より短い寸法としておくと、空気放出の時に外部側の隙間へ挟み込まれて空気流路を塞ぐことを防止することができることともなる。 As can be seen from the above examples, the thickness of the foot part on the side contacting the outer lid of the U-shaped elastic body is made thinner, and the deformation amount at the time of attaching the foot part tip on the outer lid side is determined from the opposite side. By making it small, the operation start pressure of the elastic body foot becomes smaller than the operation start pressure of the elastic body foot on the groove side, and stable gas outflow can be made possible. Furthermore, if the leg length of the elastic body is set to be shorter than the side of the square groove, it is possible to prevent the air flow path from being blocked by being sandwiched in the external gap when air is released.
電池収納部から気体が流れる他のシール部にこの溝を設けた場合に同様の効果がえられることは言うまでもなく、更に、本構造の溝部及びこれに対応するＵ字状弾性体を複数個設けると、より信頼性が高まる構造となることも言うまでもない。 Needless to say, the same effect can be obtained when this groove is provided in another seal part through which gas flows from the battery housing part, and a plurality of U-shaped elastic bodies corresponding to this groove part are provided. Needless to say, the structure is more reliable.
本発明の電池収納部圧抜シール構造は、上記のようにきわめて優れた特徴を有すると共に、従来より殆どの水中機器の電池収納部のシールにはＯリングと四角形状のＯリング溝部が用いられていることから、従来の圧抜き機構を持たない密閉用Ｏリング溝部を小さな寸法変更だけで本発明の構造に変更できる。そして、専用の取りつけ場所を確保せずに、圧抜き構造を実現できることとなった。このため、水中で使用される機器の全てについて適用可能であり、その工業的価値は著しく高い。 The battery housing pressure relief seal structure of the present invention has extremely excellent characteristics as described above, and an O-ring and a rectangular O-ring groove are used for sealing the battery housing portion of most underwater devices. Therefore, the sealing O-ring groove portion having no conventional pressure release mechanism can be changed to the structure of the present invention only by a small size change. And it became possible to realize a pressure relief structure without securing a dedicated mounting location. For this reason, it is applicable to all devices used in water, and its industrial value is remarkably high.
