Is known (for example, Patent Document 2).
JP 2004-172099 A (Claim 1) JP-A-57-143261 (Claim 1)

しかしながら、特許文献１及び特許文献２の蓄電池排気構造及び蓄電池用液漏れ防止装置は、蓄電池を上下に真逆さまにしたような場合でも電解液の漏れを避けることが出来るようなものではなかった。鉛蓄電池は振動などで傾いて電解液の漏れなどが発生することがあるが、使用中に真逆さまにすることはあまりない。しかし、輸送その他の場合は蓄電池がそうした状態となることもない訳ではなかった。   However, the storage battery exhaust structure and the storage battery liquid leakage prevention device disclosed in Patent Documents 1 and 2 are not such that leakage of the electrolyte can be avoided even when the storage battery is turned upside down. A lead-acid battery may be tilted by vibrations and cause leakage of electrolyte, but it is not often turned upside down during use. However, in the case of transportation and other cases, the storage battery was not in such a state.

この発明は、電解液を用いた蓄電池を如何なる状態にしても、たとえこれを真逆さまに転倒しても電解液の漏れ出しを防ぐ難漏性を向上させた蓄電池の二重蓋排気構造を得ようとするものである。   The present invention seeks to obtain a double lid exhaust structure for a storage battery that has improved leakage resistance to prevent leakage of the electrolytic solution even if the storage battery using the electrolytic solution is in any state, even if it is turned upside down. To do.

この発明は、蓋本体と上蓋で形成される蓄電池用二重蓋排気構造において、蓋本体の内側に、電槽のセル室に対応して区画する蓋本体隔壁を設けるとともに排気通路を形成し、該排気通路の底面に電槽の各セル室内に対応して２個のガス排気孔をそれぞれ設け、そのガス排気孔の一方にはセル室に向けて長く伸びる長筒を、他方のガス排気孔には同様のセル室に向けて短く伸びる短筒を取り付け、その長筒および短筒の上端面を互いに同一面としたことを特徴とする蓄電池用二重蓋排気構造（請求項１）、前記ガス排気孔を、排気通路の一部を掘り下げて区画した窪地の底面に設けたことを特徴とする請求項１記載の蓄電池用二重蓋排気構造（請求項２）及び前記蓋本体の内側に防沫板を設けたことを特徴とする請求項１記載の蓄電池用二重蓋排気構造である。   In the double lid exhaust structure for a storage battery formed by a lid body and an upper lid, the present invention provides a lid body partition wall that divides corresponding to the cell chamber of the battery case inside the lid body and forms an exhaust passage, Two gas exhaust holes are provided on the bottom of the passage corresponding to each cell chamber of the battery case, one of the gas exhaust holes has a long cylinder extending long toward the cell chamber, and the other gas exhaust hole has A double-cylinder exhaust structure for storage battery (Claim 1), characterized in that a short cylinder extending short toward the same cell chamber is attached, and the upper end surfaces of the long cylinder and the short cylinder are flush with each other. A double lid exhaust structure for a storage battery (Claim 2) according to claim 1 and a splash-proof plate provided inside the lid body according to claim 1, wherein the exhaust lid is provided on a bottom surface of a depression that is formed by digging a part of the exhaust passage. The double battery for storage battery according to claim 1 An exhaust structure.

この発明によれば、蓄電池を真逆さまにしても、電槽の電解液が排気室に漏れるのを防止することができ、蓄電池の振動などによっては電解液の漏れはより確実に防止することができるものである。しかも、この発明によれば蓄電池内で発生した排気ガスは、従来と同じように排気室の排気通路からフイルターを経て安全に外部に排出されるものである。   According to the present invention, even when the storage battery is turned upside down, the electrolytic solution in the battery case can be prevented from leaking into the exhaust chamber, and the leakage of the electrolytic solution can be more reliably prevented depending on the vibration of the storage battery. It can be done. Moreover, according to the present invention, the exhaust gas generated in the storage battery is safely discharged from the exhaust passage of the exhaust chamber through the filter as in the conventional case.

この発明の二重蓋排気構造を有する鉛蓄電池は、図５に示すように電槽１００とこれに熱融着されて施された蓋本体１１と上蓋１２とからなる二重蓋とからなる。電槽１００の内部は図示されていないが、隔壁により６個のセル室に区画され、各セル室には正負極板をセパレータを介して交互に積層した極板群が収納され、かつ多量の電解液が注液されている。この構成は従来と同様で相違する点はない。電槽の開口部には蓋本体１１が熱融着され、その上の一部に上蓋が熱融着されている。図５で蓋本体１１の上面に突出しているのは正負極端子１３，１４である。   As shown in FIG. 5, the lead storage battery having a double lid exhaust structure of the present invention comprises a battery case 100, and a double lid comprising a lid body 11 and an upper lid 12 that are heat-sealed to the battery case 100. Although the inside of the battery case 100 is not shown, it is divided into six cell chambers by partition walls, and each cell chamber contains a group of electrode plates in which positive and negative electrode plates are alternately stacked via separators, and a large amount The electrolyte is being injected. This configuration is the same as the conventional one and there is no difference. The lid body 11 is heat-sealed to the opening of the battery case, and the upper lid is heat-sealed to a part of the lid body 11. In FIG. 5, the positive and negative terminals 13 and 14 protrude from the upper surface of the lid body 11.

図２は蓋本体１１の上面図、図１は上蓋１２の裏面図である。蓋本体１１の上面には排気通路用凹部１５が形成されている。この凹部１５の一部に更に一段と深く窪んだ窪み部１６が設けてある。この一段と深く窪んだ窪み部１６の底面にガス排気孔２０，２１が各セル室に対応して二個ずつ形成されている。この二つのガス排気孔２０，２１の一方にはセル室に向けて長く伸びる長筒２３を設け、また他方のガス排気孔には同様のセル室に向けて短く伸びる短筒２４を取り付け、その長筒２３および短筒２４の上端面を互いに同一面とするものである。この状態はその要部を拡大して図３（Ａ）に示されている。図３（Ａ）１で１８は外部排出孔、１９は防沫板である。なお、凹部１５内は壁（凹部内壁）２５により区画されている。   FIG. 2 is a top view of the lid body 11, and FIG. 1 is a back view of the top lid 12. An exhaust passage recess 15 is formed on the upper surface of the lid body 11. A recessed portion 16 that is further deeply recessed is provided in a part of the recessed portion 15. Two gas exhaust holes 20 and 21 are formed on the bottom surface of the recessed portion 16 which is deeply recessed corresponding to each cell chamber. One of the two gas exhaust holes 20 and 21 is provided with a long tube 23 extending long toward the cell chamber, and the other gas exhaust hole is provided with a short tube 24 extending short toward the same cell chamber. The upper end surfaces of the long cylinder 23 and the short cylinder 24 are flush with each other. This state is shown in FIG. In FIG. 3 (A) 1, 18 is an external discharge hole, and 19 is a splash-proof plate. The interior of the recess 15 is partitioned by a wall (recess inner wall) 25.

一方、図１に示す上蓋１２の裏面も、蓋本体と同様に壁２６（凹部内壁）により区画されていて、これを蓋本体１１の排気通路用凹部１５に重ねて互いに融着することでこの間で排気室が形成されるようにする。上蓋１２の裏面には左右両面にはフイルター１７，１７が、円形のフイルター収納部２７に収納されて取り付けられ、その端部が外部排出孔１８，１８と連結されている。   On the other hand, the back surface of the upper lid 12 shown in FIG. 1 is also partitioned by a wall 26 (inner wall of the recess) in the same manner as the lid body, and this is overlapped with the recess 15 for the exhaust passage of the lid body 11 and fused together. In this way, an exhaust chamber is formed. Filters 17, 17 are housed and attached in a circular filter housing portion 27 on both the left and right sides of the back surface of the upper lid 12, and end portions thereof are connected to the external discharge holes 18, 18.

そして蓄電池内でガスが発生すると、ガスは蓋本体１１の底面の一段と窪んだ窪み部１６に設けたガス排気孔２０，２１から、排気通路用凹部１５内に入り、Ｐの字状に形成された壁２５，２６に沿って周回して、上蓋１２の左右両面に形成されたフイルター１７，１７を通って外部排出孔１８，１８より外部へ安全に排出されるものである。図４は上蓋の側面図である。図４に示すように防沫板１９は上蓋裏面に突出して形成され、この防沫板１９のテーパ部が蓋本体のガス排気用の長筒及び短筒近傍に設けられた壁２５に対峙して形成された双璧２８に嵌合して融着し、その下端と蓋本体のガス排気孔が形成された底面との間に隙間を形成するようにする。   When gas is generated in the storage battery, the gas enters into the exhaust passage recess 15 through the gas exhaust holes 20 and 21 provided in the recessed portion 16 which is recessed at the bottom of the lid body 11, and is formed in a P-shape. It circulates along the walls 25 and 26, passes through the filters 17 and 17 formed on the left and right sides of the upper lid 12, and is safely discharged to the outside through the external discharge holes 18 and 18. FIG. 4 is a side view of the upper lid. As shown in FIG. 4, the splash-proof plate 19 is formed so as to protrude from the back surface of the upper lid, and the tapered portion of the splash-proof plate 19 faces the wall 25 provided in the vicinity of the long and short tubes for gas exhausting of the lid body. A gap is formed between the lower end of the lid 28 and the bottom surface of the lid body where the gas exhaust holes are formed.

このように形成された二重蓋排気構造は、蓄電池が上下真逆さまに転倒した場合に、蓄電池内の電解液が長筒２３及び短筒２４の両者の孔を塞ぐために気液の置換が行い得なくなり、電槽内の電解液がこれらの孔を通って蓋本体の凹部内に漏れ出ることがなくなるものである。この状態を図３に基づいて更に説明する。   In the double lid exhaust structure formed in this way, when the storage battery is turned upside down, the electrolyte in the storage battery closes the holes of both the long cylinder 23 and the short cylinder 24, so that gas-liquid replacement cannot be performed. The electrolytic solution in the battery case does not leak into the recess of the lid body through these holes. This state will be further described with reference to FIG.

図３は蓄電池構造を正立或いは転倒させた場合のガス排気孔の状態を示したもので、（Ａ）は蓄電池を正立させた場合の二重蓋排気構造３０のガス排気孔の状態を示したものである。同図（Ａ）で１００が電槽、３１が電槽１００内を区画する隔壁、１１が蓋本体、３３が蓋本体隔壁で、電槽１００の隔壁３１と互いに向き合い熱融着されている。１２が上蓋、１５が排気通路用凹部、１８が外部排気孔である。１９は防沫板である。２３は、二つのガス排気孔の一方に取り付けられた長筒２３、２４は他方のガス排気孔に取り付けられた短筒で、いずれも同一のセル室に向けて取り付けられ、その長筒および短筒の上端面を互いに同一面とするものである。この状態では、充放電により電槽内からガスが発生した場合は、ガス排気孔から凹部１５に侵入し、Ｐの字型の壁に沿い周回しながら上蓋のフイルターを通って外部排出孔１８から排出されるものである。なお、電槽１００内には電解液が注入されているが図示していない。   FIG. 3 shows the state of the gas exhaust holes when the storage battery structure is upright or overturned, and FIG. 3A shows the state of the gas exhaust holes of the double lid exhaust structure 30 when the storage battery is upright. Is. In FIG. 2A, 100 is a battery case, 31 is a partition wall that partitions the battery case 100, 11 is a lid main body, and 33 is a lid body partition wall, facing the partition wall 31 of the battery case 100 and being heat-sealed. Reference numeral 12 denotes an upper lid, 15 denotes an exhaust passage recess, and 18 denotes an external exhaust hole. Reference numeral 19 denotes a splash-proof plate. 23 is a long cylinder 23 and 24 attached to one of the two gas exhaust holes, and short cylinders 24 are attached to the other gas exhaust hole, both of which are attached to the same cell chamber. The upper end surfaces of the cylinder are flush with each other. In this state, when gas is generated from the inside of the battery case due to charging / discharging, the gas enters the recess 15 through the gas exhaust hole, passes through the filter of the upper lid while circulating around the P-shaped wall, and from the external discharge hole 18. It will be discharged. In addition, although electrolyte solution is inject | poured in the battery case 100, it is not illustrated.

また、この蓄電池が上下逆さまに転倒した場合は、電槽内の電解液は図３（Ｂ）のように、長筒及び短筒の上面が同一平面に形成されているので、気液の置換を行うことができず互いにバランスして止まって、電槽内の電解液２９が凹部１５に漏れ出ることがない。そして、蓄電池を再び正立の位置に戻すと図３（Ｃ）のようになり、ガス排気孔２０，２１の長筒２３および短筒２４内の電解液は電槽内に還流して、凹部１５に残留するようなことはない。   In addition, when the storage battery is turned upside down, the electrolyte solution in the battery case is replaced with gas-liquid because the upper surface of the long tube and the short tube are formed in the same plane as shown in FIG. And the electrolyte solution 29 in the battery case does not leak into the recess 15. Then, when the storage battery is returned to the upright position again, as shown in FIG. 3C, the electrolytic solution in the long cylinder 23 and the short cylinder 24 of the gas exhaust holes 20 and 21 is recirculated into the battery case. 15 does not remain.

以上のように、この発明の二重排気構造によると蓄電池を真逆さまの横転状態にしても電解液が外部に漏洩するようなことなく、蓄電池内部で発生したガスは液を伴うことなく安全に外部に排出することが出来る。   As described above, according to the double exhaust structure of the present invention, even when the storage battery is turned upside down, the electrolyte does not leak to the outside, and the gas generated inside the storage battery can be safely supplied without liquid. It can be discharged to the outside.
