Generally, a lead-acid battery has a structure in which an electrode 23, an electrolyte 24, etc. are housed in a lead-acid battery container 22, as shown in FIG. In such a lead-acid battery, when the electrolyte 24 decreases and the electrode 23 is exposed, the exposed portion deteriorates, causing a decrease in the electrical capacity of the lead-acid battery.

述の劣化を未然に防止している。 Therefore, a battery checker 21 that takes advantage of the fact that the electrical capacity of a lead acid battery corresponds to the specific gravity of the electrolytic solution 24 is installed in the container 22, and displays the liquid level position and electrical capacity on the electrolytic solution 24. This prevents the above-mentioned deterioration.

ツテリチエツカーを提案した。 As a conventional example of this battery checker, the inventor of the present invention previously proposed a battery checker described in Japanese Utility Model Publication No. 1092/1983.

面に表示する光反射層１５を設けている。 That is, as shown in FIG. 2, a cylindrical cavity 12 communicating with the outside of the transparent body is provided inside a rod-shaped transparent body 11 whose upper surface is the display surface, and a specific gravity is provided in the cylindrical cavity 12. A first colored spherical float 13 whose specific gravity is smaller than the specific gravity of the electrolytic solution during charging and larger than the specific gravity during overdischarge, and a second colored spherical float 13 whose specific gravity is within the range of the specific gravity of the electrolytic solution during charging. Spherical float 14
The structure accommodates the following. Moreover, the vertical length of the circumferential cavity 12 is approximately three times the diameter of both floats 13 and 14, and the side wall of the rod-shaped transparent body 11 is located midway between the vertical length of the cylindrical cavity 12. A light reflecting layer 15 is provided on the upper surface of the rod-shaped transparent body 11 to indicate the presence or absence of the floats 13 and 14.

Here, in order to prevent the electrolytic solution 24 from decreasing and exposing the electrode 23, the display must be displayed when the liquid level of the electrolytic solution 24 is located above at least the upper end of the electrode 23. On the other hand, the closer the liquid level position of the electrolytic solution 24 is displayed to the upper end of the electrode 23, the more efficiently the lead-acid battery can be used to its limit.

極２３近くまで下げようとしても、それには機構
上の制約があつた。 By the way, as described above, in the conventional battery checker shown in FIG. 2, a protrusion 18 is provided at the lower end of the rod-shaped transparent body 11, and the colored floats 13 and 14 are housed under this protrusion 18 in a vertically movable manner. It has a configuration in which a cylindrical cavity 12 and a light reflecting layer 15 for detecting the magnitude of specific gravity are arranged. That is, there is a difference in height between the electrolyte level detection section and the electrolyte specific gravity detection section. Therefore, in the conventional structure, the electrolyte specific gravity detection section is located below the electrolyte level detection section, so even if it is attempted to lower the position of the electrolyte level detection section to near the electrode 23, there are mechanical constraints. It was hot.

ことができない。 In this way, in the structure of the conventional battery checker, when the electrolyte decreases and the liquid level reaches the lower end of the protrusion 18, an indication that the electrolyte is insufficient is displayed. The display is made earlier by the distance A to the lower end of the protrusion 18. In this case, the indication that the electrolyte is insufficient is displayed earlier than the time when the electrolyte actually needs to be replenished, and the lead-acid battery cannot be used efficiently.

It is characterized by a protruding structure.

Float storage part 4 equipped with a space 3 in which the float can move up and down
is provided. A light reflecting layer 6 is provided at the lower end of the transparent body 1 so that the position of the float 2 can be monitored from the display surface. On the lower end side wall of the transparent body 1 on the side of the float accommodating part 4, there is a triangular prism shape with two sides of 90 degrees, which serves as a reference line when indicating that the electrolyte has decreased from a set position. A right-angled prism-shaped protrusion 5 is provided so as to protrude so that its ridge line is located in the horizontal direction (see FIG. 6).

If there is enough electrolyte and the specific gravity of the electrolyte is greater than the specific gravity of the float 2, the float 2 will move within the space 3 and be located above it, and at this time, the display surface at the top of the transparent body 1 will be displayed. The color of the accommodating portion 4, for example green, is reflected by the light reflecting layer 6, and the display screen is displayed in green. When the specific gravity of the electrolytic solution becomes smaller than the specific gravity of the float 2, the float 2 moves within the space 3 and is located below it, and at this time, the color of the float 2, for example red, is displayed on the display surface at the upper end of the transparent body 1. is reflected by the light reflecting layer 6, and a red color is displayed all over the display surface.

る際の基準線となる。 Next, the function of displaying the electrolyte level by the protrusion 5 will be explained. When the electrolyte is at a level above the protrusion 5, the light incident from the display surface of the transparent body 1 is reflected from the light reflecting layer 6 and further enters the two slopes of the protrusion 5. Since this slope is immersed in the electrolyte, the incident light is directly emitted into the electrolyte. Therefore, since the reflected light does not return to the display surface of the transparent body 1, the image of the protrusion 5 cannot be seen. On the other hand, the electrolyte decreases and the position of the liquid level changes.
When the angle is lower than 1 , the protrusion 5 having an apex angle of 90° will float above the surface of the electrolyte. Then, the light incident from the display surface of the transparent body 1 is reflected by the light reflection layer 6, further totally reflected by the two 45° slopes of the protrusion 5 with an apex angle of 90°, and is displayed again via the light reflection layer 6. Come back to the surface. The portion of the side surface of the transparent body 1 other than the portion where the protrusion 5 is formed is perpendicular to the incident light, so the light exits from that surface and the reflected light does not return. Therefore, the portion corresponding to the bottom surface of the protrusion 5 is displayed as a white band on the display surface. At this time, since the horizontal straight portion corresponding to the ridgeline of the protrusion 5 is not reflected, that portion appears on the display screen as a black line B in the above-mentioned upper and lower white bands of total reflection light. This line B serves as a reference line for displaying the liquid level position when the electrolyte decreases.

In this embodiment, a colored spherical float 2 having a specific gravity greater than that of the colored spherical float 2' is positioned below within the space 3. The specific gravity of the float 2' is 1.15 and the color is red, the specific gravity of the float 2 is 1.2 and the color is green, and the color of the float accommodating section 4 is yellow.

When the amount of electrolyte is sufficient and the specific gravity of the electrolyte is 1.2 or more, the float 2' moves upward and the float 2 moves in the middle within the space 3, and the float is placed on the display surface of the transparent body 1. 2 is displayed in green. When the specific gravity of the electrolyte reaches 1.2 to 1.15, the float 2' and the float 2 are located between the protrusion 5 and the upper and lower ends of the space 3, respectively, and a yellow display of the float accommodating section 4 is displayed on the display surface. Ru. When the specific gravity of the electrolytic solution becomes 1.15 or less, the float 2 is located below the space 3, the float 2' is located in the middle, and the float 2' is displayed in red on the display screen.

A light reflecting layer 6 is provided on the side wall of the lower end of the transparent body 1 on the side of the float accommodating portion 4 to monitor the position of the electrolyte from a display surface. Since the protrusion 5 that serves as a reference line is configured to protrude, the position of the liquid level displayed is closer to the upper end of the electrode than in the past to prevent the electrolyte from decreasing and exposing the electrode.

As described above, in the present invention, a float accommodating section is provided on the side surface of the lower end of the rod-shaped transparent body whose upper end is the display surface, and the float accommodating section is provided with a float accommodating section whose specific gravity is smaller than the specific gravity of the electrolyte in the charged state. storing at least one colored float larger than the specific gravity in the discharge state;
A light reflecting layer is provided to reflect the position of the colored float on the display surface of the rod-shaped transparent body, and a protrusion in the shape of a triangular prism with an angle of about 90° between two side surfaces is provided to detect the electrolyte level. ing. As a result, the position of the electrolyte level detection part and the position of the electrolyte solution specific gravity detection part are different from those of the conventional structure in which a colored float storage part for checking the electrolyte specific gravity was provided below the rod-shaped transparent body. This means that they can be made to almost the same height.
Therefore, the position of the electrolyte level detection part, which was conventionally limited due to the colored float storage part, can be brought closer to the electrodes of the lead-acid battery.
Appropriate electrolyte level detection becomes possible. In this way, according to the present invention, the restriction on the height of the detection level due to the structure itself is eliminated, and the lead-acid battery can be used efficiently until it approaches its limit.
