Description

  The present invention relates to a lead-acid battery, a lead-acid battery package, and a lead-acid battery transport method.

  Among lead storage batteries for automobiles and the like, those that do not require maintenance such as replenishment of electrolyte solution have a structure that exhausts the gas generated inside the battery as in Patent Document 1, for example. . Specifically, as shown in FIGS. 5A and 5B, the lid 2 that closes the opening of the rectangular parallelepiped battery case 1 has a plurality of electrodes in which a positive electrode plate and a negative electrode plate are opposed to each other with a separator interposed therebetween. A plurality of valves 2a corresponding directly above each of the plurality of cell chambers containing the plate group and the electrolyte solution, and a communication path having one end serving as an exhaust port 2b while communicating the plurality of valves 2a ing. When the lead storage battery is placed on the vehicle, the exhaust port 2b is connected to the exhaust pipe 5 so that the gas generated inside the battery is exhausted collectively. In FIG. 5, the communication path is formed by closing the valve 2 a immediately above by the upper lid 2 d while communicating adjacent valves 2 a through the communication hole 2 c.

  Since such a lead storage battery has a structure in which the electrolytic solution can flow inside the battery case 1, attention is paid to avoid the so-called top-and-bottom use when packing and transporting or loading. However, when transporting or loading, there is a case where the use of the top and bottom is not observed due to large peristalsis and the randomness of workers. If it does so, electrolyte solution will overflow from the exhaust port 2b, and if an operator does not notice this overflowed electrolyte solution, an operator will touch the sulfuric acid which is electrolyte solution, and will be damaged.

  In order to avoid such a problem, Patent Document 2 proposes to provide a filter that has air permeability but does not allow moisture to pass in the vicinity of a portion corresponding to the exhaust port 2b.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram partially showing an example of the lead storage battery of the present invention. The lead storage battery includes a plurality of electrode plates (not shown) in which a positive electrode plate and a negative electrode plate are opposed to each other with a separator interposed therebetween, and a plurality of partition plates in order to accommodate the electrode plates and the electrolyte solution. The battery case 1 has a rectangular parallelepiped shape that is divided into cell chambers and is open at the top, and a lid 2 that closes the opening of the battery case 1. The lid 2 has a plurality of valves 2a corresponding to the respective cell chambers of the battery case 1 and a communication path having one end serving as an exhaust port 2b while communicating the plurality of valves 2a. ing. In FIG. 1, similarly to FIG. 5, the communication path is formed by closing the valves 2 a together with the upper lid 2 d while connecting the adjacent valves 2 a through the communication holes 2 c. In addition, a plurality of electrode plates are connected in series or in parallel, and positive and negative terminals 3 are respectively projected from the lid 2.

  In the first embodiment, one end of the spirally wound tube 4 is connected to the exhaust port 2b, and the wound part of the tube 4 is directly below the exhaust port 2b. Confronted. And in this state, as shown in FIG. 6, the lead acid battery and the tube 4 are accommodated in the box 6, and become the package of a lead acid battery.

  After the lead storage battery of this embodiment is manufactured in a factory, as shown in FIG. 6, it is accommodated in the box 6 and is transported to a warehouse as a package, or is transported to a dealer. Alternatively, the lead storage battery itself may be transported without being placed in the box 6. Similarly, the product is transported from the wholesaler to the retailer or from the retailer to the consumer in the state of the package or the lead storage battery itself. If transported in this way, the electrolyte can be transported without leaking from the lead-acid battery to the outside, which is safe for the operator.

  FIG. 2 is a side view of the lead storage battery according to the present embodiment on the side surface 1 a of the battery case 1. The lead storage battery of the present embodiment has a configuration in which the tube 4 is wound over 360 ° starting from directly below the exhaust port 2b. In such a form, the tube 4 has a portion A exceeding 360 °, so that even if the lead storage battery is swung while the side surface 1b of the battery case 1 is placed on the bottom surface, it overflows into the communication path. The electrolytic solution stops in the middle of the tube 4 wound in a spiral shape. That is, since the electrolyte does not exceed A in the tube 4 and reaches the tube outlet (the other end of the tube 4), the electrolyte does not overflow from the tube 4. Therefore, it can prevent that an operator touches electrolyte solution directly, and can work safely.

  As a material of the tube 4, a polyethylene synthetic resin, a polypropylene synthetic resin, a polyamide synthetic resin, rubber, or the like can be used. Further, if the tube 4 is closed with a resin filter 4a (preferably a filter made of a material that is breathable and does not allow liquid water to pass through), the tube 4 can be It is possible to suppress the deformation of the battery case while preventing the electrolytic solution accumulated therein from leaking. As the resin filter 4a capable of exhibiting such an effect, a water-repellent porous body (a porous body such as polytetrafluoroethylene) can be used.

(Embodiment 2)
FIG. 3 is a diagram partially showing an example of the lead storage battery of the present invention. The lead storage battery of the present embodiment has a configuration in which the tube 4 is wound over 450 ° starting from directly under the exhaust port 2b. In such a form, since there is a portion B exceeding 450 ° in the tube 4, even if the tube 2 is swung with the top surface of the lid 2 placed on the bottom surface (inverted state), the electrolyte solution is in the tube. 4, the electrolyte does not overflow from the tube 4 because it does not exceed B and reach the tube outlet.

(Embodiment 3)
FIG. 4 is a diagram partially showing an example of the lead storage battery of the present invention. The lead storage battery of this embodiment has the form which made the front-end | tip of the tube 4 oppose the other side surface 1b adjacent to the side surface 1a directly under the exhaust port 2b among the side surfaces of a battery case. That is, the tube 4 is wound around the side surface 1a, and the end serving as the outlet of the tube 4 is bent toward another side surface 1b. In such a form, the electrolyte solution overflows from the tube 4 even when the tube 4 is placed with the side surface 1a of the battery case 1 as the bottom surface because of the tip portion C facing the side surface 1b. Disappears.

  If all the above Embodiments 1 to 3 are combined, the electrolyte solution can be prevented from overflowing from the tube 4 regardless of the state in which the lead storage battery and the package are placed. Become.

  In many cases, the lead-acid battery is mounted on the vehicle by an operator having specialized knowledge. In order for this operator to determine whether or not the electrolyte solution has leaked from the exhaust port 2b into the tube 4, it is desirable that the material of the tube 4 is such that the electrolyte solution can be visually recognized. With such a configuration, an on-board operator can notice the leakage of the electrolytic solution, so that it is possible to prevent the worker from being damaged by touching the overflowing electrolytic solution when removing the tube 4. In addition, if the valve 2a can be opened and closed, it is possible to grasp the total amount of the overflowing electrolyte solution with a nominal amount and supplement the lead storage battery with a new electrolyte solution accordingly. Specifically, the electrolyte solution can be visually recognized by making the material of the tube 4 transparent or a semi-transparent material with a light color tone.

  In addition, the wound tube 4 is not simply opposed (for example, hung) to the side surface 1a of the battery case 1 immediately below the exhaust port 2b, but the lead-acid battery and the tube 4 are brought into contact with the side surface 1a. And the packing performance is improved (it is easy to put in the box), and when the package is transported, the tube 4 also adheres to the inner surface of the box, so that the lead-acid battery does not excessively move inside the box. As a result, the electrolyte is more difficult to overflow. In order to bring the tube 4 into contact with the side surface 1a, the tube 4 may be fixed to the side surface 1a using an adhesive tape, an adhesive, or the like.

  The lead-acid battery using the present invention has high safety because the electrolyte does not easily leak even if it is transported or loaded a little roughly. Therefore, it is very useful industrially.
