It relates to an automatic feeder.

Conventionally, when the electrolyte stored in the battery case constituting the storage battery has decreased below a specified level, the upper lid attached to the upper part of the battery case is opened, and the replenisher (specifically purified water) ).
However, it is time-consuming and time-consuming for the worker to perform the replenishment work as described above regularly, and there is a problem that work efficiency is low.
Therefore, in order to solve such problems, in recent years, a technology related to an automatic feeder that automatically supplies a replenisher has been developed, and an invention has already been disclosed in relation to this.

In Patent Document 1, a battery replenisher automatic injection device is named “Battery replenisher injection tube, battery replenisher automatic injection device using the tube, and battery replenisher automatic injection method using the device”. The invention related to the above is disclosed.
Hereinafter, the invention disclosed in Patent Document 1 will be described. In the invention disclosed in Patent Document 1, the battery replenisher is filled with a predetermined amount of battery replenisher and the opening of the battery replenisher is formed by sealing the opening with a lid. The mounting part that reaches the bottom of the container for the battery is crowned and sealed in the battery replenisher container opening, while the liquid level determination port at the other end of the venting tube approximately matches the normal position of the battery liquid. After adjusting the temporarily fixed location of the positioning piece, and mounting the injection port on the battery replenishment port so that the insertion amount is regulated by the positioning piece, the top and bottom of the liquid replenishing liquid container are reversed, Keep the tip of the ventilation tube in the container so that it protrudes from the surface of the battery replenisher, and the height of the mounting part that is crowned and sealed in the battery replenisher container opening And characterized by being adapted to hold at a position higher than the over supply port.

However, in the invention disclosed in Patent Document 1, if the capacity of the battery replenisher container is large, the replenisher is excessively supplied into the battery, and it is difficult to maintain the battery liquid below the upper limit level. There is sex.
In addition, since a tube having a double structure in which the ventilation tube is inserted so as to be substantially concentric is used as the liquid supply tube, it is difficult to use a general-purpose tube. Therefore, it may be difficult to manufacture simply and inexpensively.

  The present invention has been made in response to such a conventional situation, and the liquid level of the electrolytic solution stored in the battery case can be reduced to the upper limit level or less while being easily and inexpensively manufactured. An object of the present invention is to provide an automatic replenisher feeder that can be reliably maintained.

  In order to achieve the above object, the first invention is an automatic replenisher supplying device that automatically supplies a replenisher for a storage battery to a battery case in which an electrolyte is stored, and the battery case is provided at an upper edge of the battery.

In the invention having such a configuration, since the lower open end of the replenishment pipe is disposed at the same height as the lower limit line, the electrolyte stored in the battery case becomes less than the lower limit level and is replenished. The replenisher stored in the container flows down to the battery case through the refill tube. At this time, in the replenishing container, the liquid level of the replenishing liquid descends, and the volume of the space above the liquid level increases. Moreover, in a battery case, the liquid level of electrolyte solution rises. Such lowering and rising of each liquid level is caused by the pressure (P ₁ ) in which the space formed above the liquid level pushes the liquid level of the replenishing liquid, and the replenishing liquid in the replenishing container and the replenishing pipe is electrolyte the pressure to push the liquid surface (P ₂₎ total pressure of (P 1 _{+ P 2)} is stopped when commensurate with the atmospheric pressure (P ₀₎ which pushes the liquid surface of the electrolytic solution.
Therefore, the level of the electrolytic solution is always maintained at the same height as the lower limit line.

It is characterized by the following.
In the invention having such a configuration, when all of the replenisher liquid held in the replenisher container and the replenisher pipe flows down to the battery case, the electrolyte level is prevented from exceeding the upper limit line of the battery case.

Further, according to a third aspect, in the first or second aspect, the replenishing container has an opening at the upper edge thereof, a box for storing the replenisher, and a lid for opening or closing the opening. The opening is characterized in that an airtight member is provided at the periphery of the opening.
In the invention having such a configuration, in addition to the operation of the first or second invention, when the replenisher is injected into the box, the lid is operated to open the opening. When the replenisher is stored in the box, the lid is operated to close the opening.
In addition, since an airtight member is provided on the periphery of the opening, the refill container has airtightness in the latter case.

The fourth invention is characterized in that, in any one of the first to third inventions, the replenishment pipe is provided with an open / close valve for opening or closing the flow path above the upper lid.

On the other hand, when the open / close valve is closed, the replenishment liquid held in a part of the replenishment container and the replenishment pipe is prevented from flowing down when the replenishment container is opened to inject the replenishment liquid. .

Subsequently, in a fifth invention according to any one of the first to fourth inventions, the replenishment pipe is held in the attachment hole via a fixing member that immobilizes the replenishment pipe along the vertical direction. Features.
In the invention having such a configuration, in addition to the action of any one of the first to fourth inventions, the refilling pipe is prevented from moving along the vertical direction. Therefore, for example, it is possible to prevent the lower open end of the replenishment pipe from being lowered due to the load of the replenishment liquid stored in the replenishment container and less than the same height as the lower limit line.

According to the first invention, since the level of the electrolytic solution is always maintained at the same height as the lower limit line, it is possible to prevent the electrode plate inside the battery case from being exposed and deteriorated.
In addition, the first invention includes a replenishing container and a replenishing pipe, and is configured simply, so that it can be manufactured easily and inexpensively.

  According to the second invention, in addition to the effects of the first invention, the airtightness is lost due to, for example, breakage of the replenishing container, and the vacuum in the space formed above the liquid surface of the replenishing liquid is broken. Even in this case, the replenisher is not excessively replenished into the battery case. Therefore, it is possible to reliably maintain the electrolyte stored in the battery case at or below the upper limit level.

According to the third invention, in addition to the effects of the first or second invention, the replenishing container is composed of a box body and a lid body having an opening, so that the replenishing liquid can be easily injected into the replenishing container. .
Moreover, since the replenishing container has airtightness due to the airtight member, it is possible to realize a state in which the pressure (P ₁ + P ₂ ) is balanced with the atmospheric pressure (P ₀ ) as described above.

The replenisher automatic supply device according to the embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a longitudinal sectional view of a replenisher automatic supply device according to an embodiment.
As shown in FIG. 1, the replenisher automatic supply device 1 according to this embodiment is a replenisher automatic supply device that automatically supplies a replenisher solution 54 of a storage battery 50 to a battery tank 51 in which an electrolytic solution 53 is stored. is there.
The battery case 51 is provided with an upper lid 52 at its upper edge, and an upper limit line UL and a lower limit line LL when the electrolyte solution 53 is stored in the side wall 51a.
Furthermore, the replenisher automatic supply device 1 passes through the replenishment container 2 disposed above the upper lid 52 and the attachment hole 3 formed in the upper lid 52, and connects the replenisher container 2 and the battery case 51 to replenisher liquid. And a replenishment pipe 4 for allowing 54 to flow down.
Among these, the replenishing container 2 includes an opening 2b at the upper edge thereof, and includes a box 5 in which the replenishing liquid 54 is stored, and a lid 6 that opens or closes the opening 2b. Moreover, the opening part 2b is provided with a ring-shaped packing 7 which is an airtight member at the periphery thereof. A plurality of graduation lines M are displayed on the side wall 5a of the box 5 at regular intervals.

Moreover, the replenishment pipe | tube 4 is arrange | positioned by the same opening height 4a below the lower end line LL. Further, the upper open end 4 b of the refilling tube 4 communicates with a bottom hole 2 a provided at the bottom of the refilling container 2. In addition, since the replenishment pipe | tube 4 is integrally formed with the replenishment container 2, the joint of the opening end 4b and the bottom part hole 2a does not exist.
Further, the refilling pipe 4 is provided with an opening / closing valve 8 for opening or closing the flow path A above the upper lid 52. The opening / closing valve 8 opens or closes the flow path A by an operation of rotating the handle 8a about the shaft portion 8b. In addition, the replenishment pipe 4 is held in the mounting hole 3 via a fixing member 9 that fixes the replenishment pipe 4 so as not to move along the vertical direction Y. Specifically, the fixing member 9 is a ring-shaped packing provided on the peripheral edge of the refilling tube 4. In addition, the upper lid 52 is provided with a catalyst plug 55.

Next, the structure of the replenisher automatic supply device according to the embodiment will be described in more detail with reference to FIG. FIG. 2 is a longitudinal sectional view of the replenisher automatic supply device according to the embodiment. In addition, about the component shown in FIG. 1, the same code | symbol is attached | subjected also in FIG. 2, and the description is abbreviate | omitted. Also, the illustration of the open / close valve and the plurality of scale lines is omitted.
As shown in FIG. 2, the total volume V, which is the sum of the volume V ₁ inside the replenishing container 2 (the hatched portion indicated by the solid line) and the volume V ₂ inside the refilling tube 4 (the shaded portion indicated by the broken line), is the battery case 51. The volume V _{B of the} region B surrounded by the upper limit line UL and the lower limit line LL (the hatched portion by the double solid line) is less than or equal to.

Next, the operation of the replenisher automatic supply device according to the embodiment will be described in more detail with reference to FIGS. 3 and 4. 3 and 4 are longitudinal sectional views for explaining the operation of the replenisher automatic supply device according to the embodiment. The components shown in FIGS. 1 and 2 are denoted by the same reference numerals in FIGS. 3 and 4 and description thereof is omitted.
As shown in FIG. 3, in the automatic replenisher 1, the space formed above the replenisher 54 when the liquid level 53 a of the electrolyte 53 stored in the battery case 51 is positioned on the lower limit line LL. the pressure _{P 1} of the gas slightly existing in the S, the pressure replenisher 54 the sum of the pressure _{P 2} which pushes the liquid surface 53a of the electrolytic solution _{53 P (= P 1 + P} 2) is large to press the liquid surface 53a It is balanced with the atmospheric pressure _{P 0.} Therefore, the replenishment liquid 54 stored in the replenishing container 2 is not supplied to the inside of the battery case 51 via the replenishment pipe 4. Therefore, the liquid level 54a of the replenisher 54 remains positioned in the level _{D 1.}

However, when the liquid level 53a of the electrolytic solution 53 starts to fall below the lower limit line LL due to natural evaporation or electrolysis of water contained in the electrolytic solution 53, the opening / closing valve 8 is opened by the replenishment solution 54 due to its own weight. The replenishment pipe 4 flows down and is supplied to the battery case 51. As described above, since the supply continues until the pressure P is balanced with the atmospheric pressure P ₀ , the liquid level 53a finally recovers to the level of the lower limit line LL, and at the same time, the liquid level 54a of the replenishment liquid 54 has a level _{D 2} is lowered. At this time, the space S is substantially in a vacuum state (pressure P ₁ = 0).
This is because the replenishing container 2 exhibits airtightness by providing the packing 7 on the periphery of the opening 2 b of the replenishing container 2.

However, for example, when the airtightness of the replenishing container 2 is lost due to deterioration of the packing 7, that is, when the vacuum in the space S is broken, the opening / closing valve 8 is opened, so All of the replenisher 54 stored in the pipe 4 flows down into the battery case 51.
However, since the total volume V (see FIG. 2) is equal to or less than the volume V _B (see FIG. 2), the replenishment liquid 54 is inside the battery case 51 even in the above case as shown in FIG. The liquid level 53a of the electrolytic solution 53 does not exceed the upper limit line UL.

On the other hand, when the replenishment liquid 54 stored in the replenishment container 2 decreases, it is necessary to open the lid 6 and replenish the replenishment liquid 54 through the opening 2b. When the lid 6 is opened, the gas pressure P ₁ (see FIG. 3) in the space S increases abruptly. Therefore, when the open / close valve 8 is opened, the replenisher 54 is supplied to the inside of the refill container 2 and the refill pipe. 4 cannot be stored inside. Therefore, only in this case, the open / close valve 8 is operated to close the replenishment pipe 4 so that the replenishment liquid 54 can be stored inside the replenishment container 2 or the like.
In addition, since a plurality of scale lines M are displayed at regular intervals on the side wall 5a of the box 5 constituting the replenishing container 2, the replenishment liquid 54 is accurately displayed by using the scale lines M as an index. To be replenished.

  Furthermore, since the replenishment pipe 4 is held in the attachment hole 3 via the fixing member 9, the replenishment pipe 4 is prevented from moving along the vertical direction Y. Accordingly, for example, the opening end 4a is prevented from descending due to the load of the replenishing liquid 54 and being less than the same height as the lower limit line LL. In addition, according to the fixing member 9 being a packing, when the moisture contained in the electrolytic solution 53 is naturally evaporated, it is prevented from leaking to the surroundings through the mounting hole 3. Therefore, the supply amount of the replenisher 54 to the battery case 51 can be reduced as much as possible.

  As described above, according to the replenisher automatic supply device 1 according to the embodiment, when the liquid level 53a of the electrolytic solution 53 starts to fall below the lower limit line LL, the replenisher 54 is automatically supplied to the battery case 51. Can be supplied to. As a result, the liquid level 53a of the electrolytic solution 53 recovers to the level of the lower limit line LL, but the supply of the replenishing liquid 54 can be automatically stopped as in the case where the liquid level 53a is lowered. Therefore, since it is not necessary to periodically replenish the electrolytic solution 53 directly to the battery case 51, it is possible to solve the problem that the efficiency of the conventional replenishment work is low. Further, the automatic replenisher supply unit 1 includes a replenishment container 2, a replenishment pipe 4, and the like, and has a simple configuration, so that it can be manufactured easily and inexpensively.

More specifically, according to the replenisher automatic supply device 1, since the liquid level 53a of the electrolytic solution 53 automatically recovers to the level of the lower limit line LL, an electrode plate (not shown) inside the battery case 51 is provided. It can prevent exposure and deterioration.
In addition, even if the airtightness of the replenishing container 2 is lost, the replenishing liquid 54 is not excessively replenished into the battery case 51. Therefore, according to the replenisher automatic supply device 1, the liquid level 53 a of the electrolytic solution 53 stored in the battery case 51 is not more than the upper limit line UL and not less than the lower limit line LL while being easily and inexpensively manufactured. Can be reliably maintained.
Furthermore, by opening and closing the lid 6, the replenishment liquid 54 can be easily replenished into the replenishment container 2, and the liquid level 54 a of the replenishment liquid 54 stored in the replenishment container 2 can be easily confirmed. Is possible. Among these, in the latter, the time spent for confirming the liquid level 53a can be shortened.

Further, since the replenishment liquid 54 can be switched between injection into the battery case 51 and storage of the replenishment liquid 54 in the replenishing container 2 or the like by a simple operation of the opening / closing valve 8, it is easy to use.
And since the replenishment liquid 54 can be correctly replenished by using the several scale line M for the replenishment container 2, the management of the replenishment amount with a sufficient precision is attained.
In addition, since the replenishment pipe 4 is held in the mounting hole 3 via the fixing member 9, the opening end 4a is prevented from descending and becoming less than the same height as the lower limit line LL. The shortage of 53 can be stably prevented over a long period of time.

  In addition, the structure of the replenisher automatic supply device 1 of the present invention is not limited to that shown in the embodiments. For example, the refilling tube 4 may be formed separately from the refilling container 2 and a joint between the open end 4b and the bottom hole 2a may exist. The fixing member 9 may be an adhesive instead of packing.
