本発明は極板群上に７リーな電解液を蓄えた、鉛蓄電池
の電解液比重及び液面検出装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for detecting the specific gravity and level of an electrolyte for a lead-acid battery, in which a seven-lead electrolyte is stored on a group of electrode plates.
従来技術とその間照点
極板群上に７リーな電解液を蓄えた鉛蓄電池は、通常最
高液面線と最低液面線とを備え、電解液面が最低液面線
に近づくと蓄電池に補水し、電解液比重がある程度低下
すると蓄電池を補充電するものとされていた。この補水
並びに補充電時期を蓄電池から離れた場所に於て検知す
るため電解液比重及び液面検出装置が用いられる。Lead-acid batteries that store a 7-lead electrolyte on a group of electrode plates with conventional technology usually have a maximum liquid level line and a minimum liquid level line, and when the electrolyte level approaches the minimum liquid level line, the storage battery It was assumed that after water was added and the specific gravity of the electrolyte decreased to a certain extent, the storage battery would be supplementally charged. An electrolyte specific gravity and liquid level detection device is used to detect this water replenishment and supplementary charging timing at a location away from the storage battery.
検知するにはリードスイッチに接続したリード線が検知
用モニターにつながっており、リードスイッチのＯＮｌ
ＯＦＦの電気信号を検知用モニターがキャッチし表示
する仕組みになっている。To detect, the lead wire connected to the reed switch is connected to the detection monitor, and the reed switch is turned on.
The system is such that a detection monitor catches and displays the OFF electrical signal.
リードスイッチのＯＮ、ＯＦＦは、鉛蓄電池が正常な状
態ではマグネットフロートが、リードスイッチをＯＮさ
せる位置にあるが、船ａｔ池の補水並びに補充電時期に
達すると、リードスイッチがＯＦＦする位置に移動する
ことによって行われる。To turn the reed switch ON and OFF, when the lead acid battery is in normal condition, the magnetic float is in the position where the reed switch is turned ON, but when it is time to replenish the water in the ship's pond or make supplementary charge, it moves to the position where the reed switch is turned OFF. It is done by doing.
この種の電解液比重及び液面検出装置は従来から多くの

及び実開昭５５−１６１２２４号公報等が挙げられる。There have been many proposals for this type of electrolyte specific gravity and liquid level detection device, and a representative one is, for example,
Examples thereof include Japanese Utility Model Application No. 125516, Japanese Utility Model Application Publication No. 55-125517, and Japanese Utility Model Application Publication No. 55-161224.

すると、検知用モニターが、都度これをキャッチし、異
常表示を出した。すなわち点滅した。However, in all of these, an even number of sulfate radical diffusion holes provided at the bottom of the cylinder are arranged in horizontal positions shifted by 1800 degrees, that is, in positions facing each other, so that, for example, agricultural machines such as tractors, When installed on a storage battery mounted on a construction machine such as a bulldozer or a truck, or on a truck or dump truck, the electrolyte level of the storage battery may fluctuate greatly due to sudden braking or sudden leaning on a rough road. Then, the detection monitor caught this each time and displayed an abnormality message. In other words, it blinked.
この頻度は、鉛蓄電池の電解液面が最高液面線から減少
するに従って高くなった。This frequency increased as the electrolyte level of the lead-acid battery decreased from the highest level line.

ねばならなかった、等の欠点があった。On the other hand, the position of the highest liquid level of a ship's storage battery may differ depending on the model of each lead-acid battery. Therefore, for lead-acid batteries with different highest liquid level positions, there are drawbacks such as the need to prepare electrolyte specific gravity and liquid level detection devices having corresponding lengths.

Tests were also carried out on the structure of the present invention, and similar results were obtained.Also, in the product of the present invention, which has two sulfate radical diffusion holes, the angles of the upper and lower hole positions were variously changed. When the limit values for obtaining the results shown in the above table were determined, it was confirmed that the results shown in the above table could be satisfied if both hole positions were within the range of 0° to 120°.

チし異常表示することはない。Furthermore, as a result of various investigations into the diffusion behavior of sulfate radicals, it was found that according to the present invention, the total area of sulfate radical diffusion holes is approximately the same as described above. The electrolytic solution inside the cylindrical portion is difficult to flow out because the tubes are made of a plurality of tubes and are shifted within the range of 0° to 120° and arranged in a vertical relationship. Therefore, even if the electrolytic solution of the lead-acid battery fluctuates greatly, the magnetic float does not move to the position where the reed switch is turned OFF, so the detection monitor will catch it each time and no abnormality will be displayed.
すなわち検知用モニターが点滅しない。In other words, the detection monitor does not blink.

に比し抜群の効果を発揮し得る。The product of the present invention can reduce this to 14z% below the maximum electrolyte level line. That is, the product of the present invention can exhibit outstanding effects compared to conventional products.
（９上記２項に鑑み、従来品は実用に供し難いという致
命欠陥を有するが、本発明品は、これを解消する。(9) In view of the above item 2, the conventional product has a fatal defect that makes it difficult to put it into practical use, but the product of the present invention overcomes this.

。(4) In the product of the present invention, the detection monitor shows an abnormal display for the first time when the electrolyte level drops to four fins above the lowest electrolyte level line. This means that the water replenishment area has already been reached, and can be considered as a natural indication.

できる。(5) In the case of lead-acid batteries, it is preferable to replenish water when the electrolyte level reaches the middle between the highest and lowest liquid level lines. (If the electrolyte level drops too much and the specific gravity of the electrolyte increases, it will have a negative effect on the life of the lead-acid battery.) Therefore, if the distance between the highest and lowest liquid level lines is 20 fins, then the highest The same electrolyte specific gravity and liquid level detection device can be applied to lead-acid batteries in which the vertical width of the surface line has changed by 6 to 8 IWJl.
