Abstract

PURPOSE:To inspect the inside of a lead battery without damaging the battery by processing data on the quantities of the reflection and transmission of the ultrasonic wave in the battery. CONSTITUTION:Vibrations are transmitted into the lead battery 3 by an ultrasonic vibrator 2 which is supplied with energy from a generating circuit 1. Vibrations reflected in the battery are detected by an ultrasonic sensor 4 and transmitted vibrations are detected by an ultrasonic sensor 5. The data on the quantity of reflection and the quantity of transmission are A/D-converted 6 and stored in an electronic computer 7. Then, data are stored while the position relation between the vibrator 2 and sensors 4 and 5 is moved, and the respective data are processed to display the internal structure of the lead battery 2 on a CRT device 8.

[Detailed Description of the Invention] From the standpoint of the industry ■ Bean beans The present invention is a method for inspecting lead-acid batteries for internal deterioration or abnormality, and for reference in determining the quality of lead-acid batteries and when to replace them. This relates to internal inspection methods, and although a wide range of lead-acid batteries can be used, it is particularly applicable to relatively large forklift and stationary lead-acid batteries, which use a battery case made of opaque material such as ebonite. The present invention relates to an internal inspection method for lead-acid batteries that can be used effectively and effectively.

When lead acid batteries are used for many years, the anode plate, anode pole, strap, etc. corrode, and for example, if the ball becomes thin, it may discharge with a large current. Otherwise, there was a problem that it would melt and cause a malfunction. In such cases, the lead-acid battery has already reached the end of its lifespan, and it is desirable to take appropriate measures such as replacing it before it breaks down. Visually inspecting a lead-acid M battery from the outside without damaging it is completely impossible when the material of the battery case is opaque.

The same thing can be said about failures due to internal short circuits in lead-acid batteries. In other words, internal short circuits often occur when spongy lead lumps adhere and grow on the top, sides, or bottom of the electrode group, eventually creating a bridge between the anode and cathode sides.
In the past, because it was not possible to check for the growth of lead on sponges in advance, they suffered from sudden breakdowns and were either unusable until repaired or had to be used with degraded performance.

In other words, the present invention is an internal inspection method for a lead-acid battery, in which ultrasonic waves are applied from multiple directions around the lead-acid battery, and data on at least one of the amount of reflection and the amount of transmission is processed by an electronic computer. This system is characterized by outputting the internal structure of a lead-acid battery as a video. That is, the inside of a lead-acid battery is filled with dilute sulfuric acid as an electrolyte, and ultrasonic waves are well transmitted through this dilute sulfuric acid. On the other hand, when ultrasonic waves hit lead alloy parts such as electrode plates, balls, or straps, the ultrasonic waves are reflected and absorbed. From this, each time ultrasonic waves are applied from multiple directions around the lead-acid battery and data on at least one of the amount of reflection and the amount of transmission is processed by an electronic computer, 1. The internal structure of a lead-acid battery can be output as a video.
