Description

[Detailed explanation of the invention] [Industrial application field] This invention is suitable for use as an emergency power source, etc.
This invention relates to a zinc-air battery that can be used as a power source by flowing an electrolyte into the battery case.

[Conventional technology]

Conventionally, a zinc-air battery used as an emergency power source is constructed as shown in FIGS. 1 and 2, and inside a tank body 1, an upper tank 2,
A lower tank 3 is formed at the bottom, an air port 4 formed on the upper surface of the upper tank 2 is closed by a cap 5, and the upper tank 2 and the lower tank 3 communicate with each other via a tank 6. upper tank 2
An electrolyte such as a 35% caustic potash solution is stored inside. Further, below the tank body 1, a plurality of battery cases 8 each having an air electrode 7 and a zinc electrode are arranged side by side in the left and right direction. Partition plate 9 that partitions corresponding to battery case 8
are arranged in parallel, and an electrolyte supply port 10 is formed in the lower wall of each chamber of the lower tank 3 partitioned by the partition plate 9, and each of the supply ports 10 is connected through each communication path 11. Electrolyte inlet 12 of each battery container 8
is communicated with. Further, each of the supply ports 10 is closed by inserting a valve 13 from above, and each valve 13 is linked to a left-right interlocking shaft 14 supported by the tank body 1, and rotation of the interlocking shaft 14 causes each valve to be closed. 13 is moved upward to open each supply port 10, and an operating lever 15 is fixed to the end of an interlocking shaft 14 protruding from the left side wall of the tank body 1.

When turning on the power supply in an emergency, etc.,
First, the cap 5 is removed to open the air port 4, and then the pot 6 is opened to supply the electrolyte in the upper tank 2 into the lower tank 3. At this time, lower tank 3
Since the inside is partitioned by a partition plate 9 corresponding to each battery case 8, a certain amount of electrolyte is supplied to each case. Next, operate the operating lever 15 to rotate the interlocking shaft 14 and move each valve 13 upward.
With the opening of each supply port 10, the electrolyte in each chamber in the lower tank 3 flows through each communication path 11 and into each battery case 8 from each inlet 12, thereby becoming usable as a power source. .

In addition, as described in Japanese Patent Publication No. 47-39651 (57BO), a lever is used to rotate the shaft, a cutting blade fixed to the shaft breaks the thin plate attached to the electrolyte chamber, and the electrolyte is poured into the battery chamber. There are injectable batteries that inject.

[Problem that the invention attempts to solve]

However, in order to bring the conventional zinc-air battery shown in FIGS. 1 and 2 into operation as a power source, three steps are required: opening the air port 4, opening the valve 6, and operating the lever 15. Because it requires
This method has the disadvantages that it takes a lot of time and is complicated to handle, cannot adequately respond to emergencies, and has the disadvantages that the structure is also complicated.

In addition, the battery described in Japanese Patent Publication No. 47-39651 is not configured to take air into the upper part of the electrolyte chamber, so the injection speed of the electrolyte from the electrolyte chamber to the battery chamber is slow, and the electrolyte chamber and battery It is difficult to inject liquid due to its own weight unless the thin film blocking the chamber is destroyed over almost the entire surface.

This invention was made with the above points in mind.

[Means for solving problems]

Next, the operation of the embodiment will be explained.

First, the state shown in FIGS. 3 and 4 shows normal installation in a non-operating state, in which the front end of the shaft 27 is inserted into the insertion portion 30a of the shaft holder 30.
The rear end portions of 7 are held in the insertion portions 31a of the shaft holder 31, respectively. Here, the shaft 27 is urged upward by the spring 34;
The rear end part is narrow part 31 of shaft holder 31 due to its thickness.
Since the intrusion into the inside of b is suppressed, the position is maintained and the state of being supported by both shaft holders 30 and 31 is maintained.

Next, when operating as a lighting power source in an emergency or the like, when the stopper 43 of the push button 41 is removed and the push button 41 is pushed in, the shaft 42 enters the insertion portion 30a of the shaft holder 30 and pushes the shaft 27 backward.
The shaft 27 is moved rearward. And the fifth
As shown in the figure, when the front end of the shaft 27 reaches the moving part 30b of the shaft holder 30, the shaft 27
The rear end portion of the shaft holder 31 is located in the moving portion 31c, and the missing portion 29 is located in the insertion portion 31a, and the shaft 27 is free to move upward, so the shaft 27 can be moved upward by the bias of the spring 34. The front and rear ends of the shaft 27 are the moving parts 30b and 30b, respectively.
31c is moved upward, and the missing portion 29 enters the narrow portion 31b. This upward movement of the shaft 27 pushes up the cutter 33 via the connecting body 32, and the cutter 33 pushes up the lower surface of the thin plate 21, damaging the thin plate 21 and opening the supply port 19.
Furthermore, lift up the interlocking body 36 and
Due to the upward movement of , the cutter 39 of the interlocking body 36
0 and damaged the thin plate 20, causing the air hole 18
is opened. In this way, when the supply port 19 and the air hole 18 are opened almost simultaneously, the electrolyte in the electrolyte tank 17 flows from the supply port 19 to the communication path 26.
and flows into the battery case 22 through the inlet 25,
It can be used as a power source.

Therefore, according to the embodiment, in an emergency, etc.
When the power source is activated, the shaft 27 is moved upward by the spring 34 by simply pressing the push button 41, and the cutter 3 integrated with the shaft 27 is moved upward by the spring 34.
3, the thin plate 21 of the supply port 19 can be damaged, and the interlocking body 36 is moved upward in conjunction with the cutter 33, and the cutter 39 integrated with the interlocking body 36 can damage the thin plate 20 of the air hole 18, resulting in a predetermined operating state. It is very easy to handle and can be used in emergencies. Furthermore, in the above embodiment, when the shaft 27 moves upward, the interlocking body 36 is simultaneously moved upward by the shaft 27, and both the thin plates 21 and 20 are damaged almost simultaneously. Therefore, the structure can be relatively simple, and the product can be manufactured easily. It can be made cheap as

[Effects of the invention] As described above, according to the zinc-air battery of this invention, when used as a power source, by operating only the operating body 41, the supply port cutter 33 damages the supply port thin plate 21, Almost at the same time, the air hole cutter 39 breaks the air hole thin plate 20, so the air hole 1
Air flows into the electrolytic solution tank 17 from 8, and the electrolytic solution flows into the battery container 22 extremely quickly, and the operation is simple because only the operating body 41 is operated, and the operation is sufficient for emergency situations. I can handle it.
