本考案は蓄電池の電解液面検出装置の改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to an improvement of an electrolyte level detection device for a storage battery.
従来、浮玉と渦流形電極を用いた液面検出装置に於いて
は、浮玉の上下移動によって電極への接近、接触を感知
して、液面の高低を検出するのであるが、検出部と浮玉
の浮上時における接触面が平坦状であるが為に、蓄電池
充電時に極板群より発生し上昇してくる気泡が浮玉収容
室内に入り鉄車の天井面即ち検出部の底面で滞留した場
合、滞留した小さな気泡は次第に成長じて大きくなると
共に、気泡が浮玉を押し下げる力が作用して検出部と、
液面に浮上し該検出部と接触しようとする浮玉との間隔
を大きくして、検出誤動作を起こす等の欠点があった。Conventionally, in a liquid level detection device using a floating ball and an eddy current electrode, the height of the liquid level is detected by sensing the approach or contact with the electrode by the vertical movement of the floating ball. Since the contact surface of floating balls is flat, air bubbles generated from the electrode plate group and rising when the storage battery is charged enter the floating ball storage chamber and reach the ceiling of the railway car, that is, the bottom of the detection part. When the small bubbles stay, they gradually grow and become larger, and the force of the bubbles pushing down the floating ball acts on the detection part.
This method has disadvantages such as increasing the distance between floating balls that float on the liquid surface and try to come into contact with the detection section, causing detection errors.
本考案はかかる欠点を除去するものにして、渦流形電極
を備えた液面検出装置の検出部の下端に設けた浮玉収容
室の天井面即ち検出部の底面を円錐状に突出させ、且つ
浮玉収容室内径より十分に小さい直径の浮玉を前記検出
部の円錐面に沿って回転可能に浮玉収容室に収容して浮
玉に悪影響を及ぼす気泡の滞留を防ぐ構造となしたもの
である。The present invention eliminates such drawbacks by making the ceiling surface of the floating ball storage chamber provided at the lower end of the detection section of a liquid level detection device equipped with an eddy current electrode, that is, the bottom surface of the detection section protrude in a conical shape, and A floating ball having a diameter sufficiently smaller than the diameter of the floating ball storage chamber is rotatably accommodated in the floating ball storage chamber along the conical surface of the detection section to prevent air bubbles from accumulating that have an adverse effect on the floating ball. It is.
その−例を図面について説明すると、１は渦流形電極を
備えた液面検出装置本体のコイル筒、２は同装置の検出
部、３は円錐状に突出させた検出部２の底面、４は籠状
の浮玉収容室、５は透かし窓、６は浮玉収容室４の内径
より十分小さい直径の浮玉である。An example of this will be explained with reference to the drawings. 1 is the coil tube of the liquid level detection device main body equipped with an eddy current electrode, 2 is the detection section of the device, 3 is the bottom surface of the detection section 2 that projects in a conical shape, and 4 is the A cage-shaped floating ball storage chamber, 5 is a transparent window, and 6 is a floating ball having a diameter sufficiently smaller than the inner diameter of the floating ball storage chamber 4.
上記の構造を有することによって、浮玉収容室４に入っ
た気泡は浮力に従いながら円錐状に突出させた検出部２
の底面３に沿って上昇し、籠状の浮玉収容室４の透かし
窓５を通り抜けて外へ出る。By having the above structure, the air bubbles that have entered the floating ball storage chamber 4 are caused to protrude into the detection part 2 in a conical shape while following the buoyant force.
The floating ball rises along the bottom surface 3 of the floating ball, passes through the transparent window 5 of the cage-like floating ball storage chamber 4, and exits.
又、小さな気泡が検出部２の底面３に付着し、成長した
場合でも円錐の母線に沿った力が働くため、気泡は付着
力より円錐の母線方向の力が大きくなって動きだし、検
出部２の底面３の上方より浮玉収容室４の外へ排出され
る。In addition, even if a small bubble adheres to the bottom surface 3 of the detection part 2 and grows, a force along the generatrix of the cone acts, so the bubble starts to move because the force in the direction of the generatrix of the cone becomes greater than the adhesion force, and the bubble starts to move. The floating balls are discharged from above the bottom surface 3 to the outside of the floating ball storage chamber 4.
而して浮玉６が浮上して検出部２の底面３に接触した時
に於いても、検出部２の底面３が円錐状であるため、浮
玉６の上端面と前記円錐面との互いに離反する曲面の間
の近傍に十分な空間が現出して気泡による影響を受ける
ことはない。Even when the floating ball 6 floats up and contacts the bottom surface 3 of the detecting section 2, since the bottom surface 3 of the detecting section 2 is conical, the upper end surface of the floating ball 6 and the conical surface do not touch each other. Sufficient space appears in the vicinity between the separating curved surfaces and is not affected by bubbles.
又、気泡が蓄積した場合でも、浮玉は円錐状の底面３に
沿って回転することができるため、気泡を押しのける如
く動揺することによって検出部２と浮玉６の間隔は離れ
ることがないので、気泡による誤動作がないのである。In addition, even if air bubbles accumulate, the floating ball can rotate along the conical bottom surface 3, so the distance between the detection unit 2 and the floating ball 6 will not increase due to agitation to push away the air bubbles. , there are no malfunctions caused by air bubbles.
