Description

[Detailed Description of the Invention] The present invention relates to a device for detecting the specific gravity and drop in the level of an electrolyte in a storage battery or the like.

Conventionally, the specific gravity and liquid level of an electrolytic solution in a storage battery have generally been detected visually.

However, in this case, it cannot be confirmed at a location far from the storage battery, and in the case of automobile storage batteries, the detection device provided in the storage battery has the disadvantage of being dirty with dust and difficult to visually observe.

The present invention provides a structural hourly device that can detect a drop in the specific gravity and liquid level of an electrolytic solution even from a remote location using electrical signals.

Next, the principle of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a cylindrical container made of synthetic resin or the like with a semipermeable membrane 2 stretched on the bottom surface.

Two long and short specific gravity detection electrodes 3 and 4 are inserted into the container 1.

On the other hand, a liquid level detection electrode 5 whose tip is below the surface of the semipermeable membrane 2 is provided outside the container 1 .

An electrolytic solution 7 having a specific gravity before change of the electrolytic solution 6 to be detected is poured into the container 1, and only the long specific gravity detection electrode 3 is immersed.

The container 1 and the liquid level detection electrode 5 are immersed in the electrolytic solution 6 to be detected, and the liquid level of the electrolytic solution 7 in the container 1 is adjusted to the liquid level of the electrolytic solution 6 to be detected.

When the specific gravity of the electrolytic solution 6 to be detected decreases, water infiltrates into the container 1 through the semipermeable membrane 2 due to the difference in osmotic pressure.

Due to the intrusion of water, the liquid level of the electrolyte 7 in the container 1 rises,
When the short specific gravity detection electrode 4 is reached, the two long and short specific gravity detection electrodes 3 and 4 are electrically connected.

Thereby, a decrease in the specific gravity of the electrolytic solution 6 to be detected can be detected.

On the other hand, detection of a drop in the liquid level of the electrolytic solution 6 to be detected is performed as follows.

That is, if the lower end of the container 1 is below the liquid level of the electrolytic solution 6 to be detected, the long specific gravity detection electrode 3 and the liquid level detection electrode 5 are electrically connected, and the liquid level of the electrolytic solution 6 to be detected is If it is on the surface, there will be no conduction.

Thereby, a drop in the liquid level of the electrolytic solution 6 to be detected can be detected.

When applying the above-described device of the present invention to a lead-acid battery, it is preferable to do as follows.

The semipermeable membrane used is one through which water, H+, and 0H-1H30+ can pass.

The initial specific gravity of the electrolyte in the container is set to 1.260, and the liquid level is adjusted to the highest liquid level of the storage battery.

The short specific gravity detection electrode has a storage battery electrolyte specific gravity of 1.19.
The length is set so that when the temperature reaches 0, it contacts the electrolyte surface in the container.

Align the bottom of the container with the lowest electrolyte level of the battery.

With the above configuration, it is possible to electrically and reliably detect the specific gravity of the electrolytic solution of the storage battery and the drop in the liquid level.

As mentioned above, the present invention has a simple structure and is of great value in fish odor applications, as it can reliably electrically detect the specific gravity of the electrolytic solution and the drop in the liquid level.
