【発明が解決しようとする課題】
このようなバッテリ液自動補給装置は、複雑な電子制御を必要とし、高コストであることから、普及していない。
【０００５】
一般的には、容器からバッテリ内に直接バッテリ液を補給するが、バッテリの外部にバッテリ液をこぼしたり、補液量を正確に計ることができず、規定の液位となるよう正しく補液するためには、作業時間を要し、特に、多くの車両を管理する必要がある場合は、バッテリの維持管理に要する時間、労力、コストを無視できない。
【０００６】
本発明は、このような点に鑑みなされたもので、バッテリより上側に配置された容器からバッテリ内にバッテリ液を補給する低コストのバッテリ液補給装置において、バッテリ内の規定の液位を容易に得ることができるようにすることを目的とするものである。
【０００７】

【０００８】
請求項２に記載された発明は、請求項１記載のバッテリ液補給装置において、給液管の管内通路を開閉する開閉弁を具備したものであり、給液管をバッテリの給液口に挿入したり抜出したりする際に、開閉弁により給液管の管内通路を閉じることで、容器からバッテリの外部にバッテリ液をこぼすことを防止できる。
【０００９】
請求項３に記載された発明は、請求項１または２記載のバッテリ液補給装置における通気管が、少なくともバッテリ内に挿入される給液管の下部内に挿入されて一体化されたものであり、給液管とともに、少なくとも給液管の下部内に挿入されて一体化された通気管を、バッテリ内に容易に挿入でき、バッテリ液補給作業を容易にできる。
【００１０】
請求項４に記載された発明は、請求項３記載のバッテリ液補給装置において、給液管の外周面に一体的に設けられバッテリの給液口と係合して通気管の下端の開口レベルを設定する液位調整ストッパを具備したものであり、液位調整ストッパがバッテリの給液口と係合するまで、給液管をバッテリの給液口に挿入するだけで、給液管の下部内に一体化された通気管の下端の開口レベルをバッテリ内の補液後の予定液位に簡単に設定でき、各バッテリ内の規定の液位を正しくかつ容易に得られる。
【００１１】
【発明の実施の形態】
以下、本発明を図１および図２に示された一実施の形態を参照しながら説明する。
【００１２】
図１に示されるように、給液口１１を有するバッテリ１２より上側に、バッテリ１２内に補給される電解液または精製液などのバッテリ液１３を貯めた容器としての補液タンク１４が配置されている。バッテリ１２内には、極板１５およびバッテリ液１３が収容されている。
【００１３】
バッテリ１２の給液口１１は、補液時以外は液口キャップ１６により閉じられている。補液タンク１４は、図示しないホルダなどにより支持しても良いが、作業者が手で持って図示される位置に保持することで、バッテリ１２上の定位置に配置するようにしても良い。
【００１４】
この補液タンク１４の下部から、バッテリ１２の給液口１１に挿入される給液管１７および通気管１８が引出されている。
【００１５】
給液管１７は、上端に開口された開口部２１が、補液タンク１４の下部内に配置されているとともに、下端に開口された開口部２２が、バッテリ１２の給液口１１からバッテリ１２内の補液後の予定液位Ｌまで挿入されるものである。バッテリ１２内に挿入される給液管１７の下側部分には、直線部分２３が形成されている。
【００１６】
通気管１８は、その下部が、少なくともバッテリ１２内に挿入される給液管１７の直線部分２３内に挿入されて一体化され、中間部が、給液管１７の外部に引出され、上部が補液タンク１４の肩部１４ａから補液タンク１４内に挿入されたものである。
【００１７】
この通気管１８の上端に開口された開口部２４は、補液タンク１４の上部内まで挿入されているとともに、下端に開口された開口部２５は、給液管１７と一体的に、バッテリ１２の給液口１１からバッテリ１２内の補液後の予定液位Ｌまで挿入されるものである。
【００１８】
すなわち、給液管１７の下端の開口部２２がセットされる開口レベルと、通気管１８の下端の開口部２５がセットされる開口レベルは、共に補液後の予定液位Ｌに等しく設定されている。
【００１９】
さらに、給液管１７の中間部であって、通気管１８が挿通されていない部分には、給液管１７の管内通路を開閉する開閉弁２６が設けられている。この開閉弁２６は、弁本体２７と、この弁本体２７内で開閉動作する可動弁体２８と、この可動弁体２８を回動操作するレバー形の操作部２９とを備えている。
【００２０】
また、給液管１７の外周面であって、通気管１８が挿通されている下部の直線部分２３には、バッテリ１２の給液口１１の上縁と係合して通気管１８の下端の開口部２５を補液後の予定液位Ｌに設定する液位調整ストッパ３１が一体的に設けられている。
【００２１】
この液位調整ストッパ３１は、硬質部材で形成されている場合は、ねじなどにより給液管１７の外周面に固定され、ねじを弛めることにより上下方向に位置調整可能であり、また、ゴムなどの軟質部材で形成されている場合は、その軟質部材の弾力性により給液管１７の外周面に固定され、外部からの強制的な力により上下方向に位置調整可能である。
【００２２】
次に、この実施の形態の作用効果を説明する。
【００２３】
バッテリ１２の給液口１１に設けられた液口キャップ１６を外して、通気管１８を内蔵した給液管１７を給液口１１に挿入する。
【００２４】
その際、給液管１７の直線部分２３に嵌着された液位調整ストッパ３１が給液口１１の上縁に係合されると、給液管１７および通気管１８の下端の開口部２２，２５は、バッテリ１２内の補液後の予定液位Ｌにセットされる。
【００２５】
このとき、バッテリ１２内の上部空間３２は、バッテリ本体と液位調整ストッパ３１との間の間隙や、バッテリ本体の上部に穿設された図示しない通気孔を通して、常に外部と連通され、大気圧に保たれている。
【００２６】
給液管１７および通気管１８の下端の開口部２２，２５を補液後の予定液位Ｌにセットした後に、開閉弁２６の操作部２９を回動操作することで、可動弁体２８を開いてバッテリ液１３の補給を開始する。
【００２７】
このバッテリ液補給開始時は、バッテリ１２内の液面３４と、通気管１８の先端の開口部２５との間には隙間があり、通気管１８を通じて補液タンク１４内の上部空間３３に空気を吸込むことが可能である。
【００２８】
よって、補液タンク１４内の上部空間３３は大気圧に保たれる。この大気圧とバッテリ液１３自身の質量とにより、給液管１７内のバッテリ液１３は、バッテリ１２内の液面３４に滴下する。
【００２９】
一方、バッテリ１２内の液面３４が上昇して、通気管１８の下端の開口部２５に達すると、この開口部２５から補液タンク１４内の上部空間３３に空気が吸込まれなくなり、補液タンク１４内の上部空間３３の気圧は、タンク内液面３５が下降しようとすると大気圧よりも低下する。
【００３０】
すなわち、このタンク内液面３５に作用する気圧が低下するため、給液管１７内のバッテリ液に作用するバッテリ液の自重を含めた下向きの力と、給液管１７の下端の開口部２２を通じて給液管１７内のバッテリ液に作用する大気圧に基づく上向きの力とがつり合い、給液管１７内のバッテリ液の移動すなわちバッテリ液の滴下は自動的に停止する。
【００３１】
このようにして、給液管１７からのバッテリ液１３の滴下による自動給液が停止したら、開閉弁２６の操作部２９により可動弁体２８を閉じ操作して、通気管１８が一体化された給液管１７の下部をバッテリ１２の給液口１１から引抜く。
【００３２】
このように、バッテリ１２より上側に配置された補液タンク１４から給液管１７を通じてバッテリ１２内にバッテリ液１３を補給する低コストのバッテリ液補給装置において、バッテリ１２の給液口１１からバッテリ１２の上部空間３２内に給液管１７とともに挿入された通気管１８の下端の開口部２５の設置レベルにより、バッテリ１２内の規定の液位を容易に得ることができる。
【００３３】
また、給液管１７をバッテリ１２の給液口１１に挿入したり抜出したりする際に、開閉弁２６により給液管１７の管内通路を閉じることで、補液タンク１４からバッテリ１２の外部にバッテリ液１３をこぼすことを防止できる。
【００３４】
さらに、給液管１７と一体的に、少なくとも給液管１７の下部内に挿入されて一体化された通気管１８を、バッテリ１２内の上部空間３２に容易に挿入でき、バッテリ液補給作業を容易にできる。
【００３５】
その際、給液管１７に対する液位調整ストッパ３１の位置を正確に決めておけば、この液位調整ストッパ３１がバッテリ１２の給液口１１の上縁と係合するまで、給液管１７を給液口１１に挿入するだけで、給液管１７の下部内に一体化された通気管１８の下端の開口部２５のレベルを、バッテリ１２内の補液後の予定液位Ｌに簡単に設定でき、各バッテリ１２内の規定の液位を正しくかつ容易に得られる。
【００３６】
【発明の効果】
請求項１記載の発明によれば、バッテリより上側に配置された容器から給液管を通じてバッテリ内にバッテリ液を補給する低コストのバッテリ液補給装置において、バッテリの給液口からバッテリ内に挿入された通気管の下端の開口レベルにより、バッテリ内の規定の液位を容易に得ることができる。
【００３７】
請求項２記載の発明によれば、給液管をバッテリの給液口に挿入したり抜出したりする際に、開閉弁により給液管の管内通路を閉じることで、容器からバッテリの外部にバッテリ液をこぼすことを防止できる。

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS.
[0012]
As shown in FIG. 1, a replacement fluid tank 14 as a container for storing a battery solution 13 such as an electrolytic solution or a purified solution to be replenished in the battery 12 is disposed above a battery 12 having a fluid supply port 11. I have. The electrode plate 15 and the battery fluid 13 are contained in the battery 12.
[0013]
The liquid supply port 11 of the battery 12 is closed by a liquid port cap 16 except during refilling. The replenisher tank 14 may be supported by a holder (not shown) or the like, but may be held at a position shown in the figure by being held by an operator, and may be arranged at a fixed position on the battery 12.
[0014]
A liquid supply pipe 17 and a ventilation pipe 18 inserted into the liquid supply port 11 of the battery 12 are drawn out from a lower part of the replacement liquid tank 14.
[0015]
The liquid supply pipe 17 has an opening 21 opened at the upper end disposed in the lower part of the replenishing tank 14, and an opening 22 opened at the lower end connected to the liquid supply port 11 of the battery 12 through the inside of the battery 12. Is inserted up to the expected liquid level L after the replacement. A straight portion 23 is formed in a lower portion of the liquid supply pipe 17 inserted into the battery 12.
[0016]
The ventilation pipe 18 has its lower part inserted and integrated into at least the straight portion 23 of the liquid supply pipe 17 inserted into the battery 12, the middle part is drawn out of the liquid supply pipe 17, and the upper part is It is inserted into the replacement fluid tank 14 from the shoulder 14 a of the replacement fluid tank 14.
[0017]
The opening 24 opened at the upper end of the ventilation pipe 18 is inserted into the upper part of the replenisher tank 14, and the opening 25 opened at the lower end is integrated with the liquid supply pipe 17 to form the battery 12. It is inserted from the liquid supply port 11 to a predetermined liquid level L after replacement in the battery 12.
[0018]
That is, the opening level at which the opening 22 at the lower end of the liquid supply pipe 17 is set and the opening level at which the opening 25 at the lower end of the ventilation pipe 18 are both set to be equal to the expected liquid level L after rehydration. I have.
[0019]
Further, an opening / closing valve 26 that opens and closes a passage in the liquid supply pipe 17 is provided in an intermediate portion of the liquid supply pipe 17 where the ventilation pipe 18 is not inserted. The on-off valve 26 includes a valve body 27, a movable valve body 28 that opens and closes in the valve body 27, and a lever-shaped operation unit 29 that rotates the movable valve body 28.
[0020]
A lower straight portion 23 on the outer peripheral surface of the liquid supply pipe 17 through which the ventilation pipe 18 is inserted is engaged with the upper edge of the liquid supply port 11 of the battery 12 and is provided at the lower end of the ventilation pipe 18. A liquid level adjusting stopper 31 for setting the opening 25 to the expected liquid level L after replacement is integrally provided.
[0021]
When the liquid level adjusting stopper 31 is formed of a hard member, the liquid level adjusting stopper 31 is fixed to the outer peripheral surface of the liquid supply pipe 17 with a screw or the like, and the position can be adjusted in the vertical direction by loosening the screw. When it is formed of the soft member described above, it is fixed to the outer peripheral surface of the liquid supply pipe 17 by the elasticity of the soft member, and the position can be adjusted in the vertical direction by a force externally applied.
[0022]
Next, the operation and effect of this embodiment will be described.
[0023]
The liquid port cap 16 provided on the liquid supply port 11 of the battery 12 is removed, and a liquid supply pipe 17 having a built-in ventilation pipe 18 is inserted into the liquid supply port 11.
[0024]
At this time, when the liquid level adjusting stopper 31 fitted to the linear portion 23 of the liquid supply pipe 17 is engaged with the upper edge of the liquid supply port 11, the opening 22 at the lower end of the liquid supply pipe 17 and the vent pipe 18 is formed. , 25 are set to the expected liquid level L after replacement in the battery 12.
[0025]
At this time, the upper space 32 in the battery 12 always communicates with the outside through a gap between the battery main body and the liquid level adjusting stopper 31 and a vent hole (not shown) formed in the upper part of the battery main body, and the atmospheric pressure is maintained. It is kept in.
[0026]
After the opening portions 22 and 25 at the lower ends of the liquid supply pipe 17 and the ventilation pipe 18 are set to the expected liquid level L after replenishment, the operation part 29 of the on-off valve 26 is rotated to open the movable valve body 28. To start replenishment of the battery fluid 13.
[0027]
At the start of the replenishment of the battery fluid, there is a gap between the liquid surface 34 in the battery 12 and the opening 25 at the tip of the ventilation pipe 18, and air is supplied to the upper space 33 in the replenisher tank 14 through the ventilation pipe 18. It is possible to inhale.
[0028]
Therefore, the upper space 33 in the replacement fluid tank 14 is maintained at the atmospheric pressure. Due to the atmospheric pressure and the mass of the battery liquid 13 itself, the battery liquid 13 in the liquid supply pipe 17 drops on the liquid surface 34 in the battery 12.
[0029]
On the other hand, when the liquid level 34 in the battery 12 rises and reaches the opening 25 at the lower end of the ventilation pipe 18, air is no longer sucked into the upper space 33 in the refill tank 14 from the opening 25, and the refill tank 14 When the liquid level 35 in the tank is about to drop, the atmospheric pressure of the upper space 33 in the inside becomes lower than the atmospheric pressure.
[0030]
That is, since the pressure acting on the liquid surface 35 in the tank is reduced, the downward force including the weight of the battery liquid acting on the battery liquid in the liquid supply pipe 17 and the opening 22 at the lower end of the liquid supply pipe 17 are reduced. The upward force based on the atmospheric pressure acting on the battery liquid in the liquid supply pipe 17 is balanced through this, and the movement of the battery liquid in the liquid supply pipe 17, that is, the dripping of the battery liquid automatically stops.
[0031]
In this way, when the automatic liquid supply by the drop of the battery liquid 13 from the liquid supply pipe 17 is stopped, the movable valve body 28 is closed by the operation unit 29 of the on-off valve 26, and the ventilation pipe 18 is integrated. The lower part of the liquid supply pipe 17 is pulled out from the liquid supply port 11 of the battery 12.
[0032]
As described above, in the low-cost battery fluid replenishing device for replenishing the battery fluid 13 into the battery 12 from the fluid replacement tank 14 disposed above the battery 12 through the fluid supply pipe 17, the battery 12 is supplied from the fluid supply port 11 to the battery 12. The prescribed liquid level in the battery 12 can be easily obtained by the installation level of the opening 25 at the lower end of the ventilation pipe 18 inserted together with the liquid supply pipe 17 into the upper space 32 of the battery.
[0033]
Further, when the liquid supply pipe 17 is inserted into or extracted from the liquid supply port 11 of the battery 12, the passage in the liquid supply pipe 17 is closed by the on-off valve 26, so that the battery is transferred from the replacement fluid tank 14 to the outside of the battery 12. The spilling of the liquid 13 can be prevented.
[0034]
Further, the ventilation pipe 18 which is inserted at least into the lower part of the liquid supply pipe 17 and is integrated with the liquid supply pipe 17 can be easily inserted into the upper space 32 in the battery 12, so that the battery liquid supply operation can be performed. Easy.
[0035]
At this time, if the position of the liquid level adjusting stopper 31 with respect to the liquid supply pipe 17 is accurately determined, the liquid level adjusting stopper 31 is engaged with the upper edge of the liquid supply port 11 of the battery 12 until the liquid level adjusting stopper 31 is engaged. By simply inserting the liquid into the liquid supply port 11, the level of the opening 25 at the lower end of the ventilation pipe 18 integrated in the lower part of the liquid supply pipe 17 can be easily adjusted to the expected liquid level L after replacement in the battery 12. The specified liquid level in each battery 12 can be set correctly and easily.
