【考案の詳細な説明】
本考案は蓄電池の電解液の液面を検出する装置において
使用する検出用浮子の良好な動作及び加工の簡便なもの
を得ることを目的とする。[Detailed Description of the Invention] The object of the present invention is to obtain a detection float that operates well and is easy to process, for use in a device for detecting the liquid level of an electrolyte in a storage battery.
従来、この種の液面検出用浮子としては液中に浮かせ糸

コイルへの遠近により発振に強弱が生じることを利用し
、これを分別回路を経て表示する方式がある。Conventionally, this type of float for liquid level detection has been made by floating it in the liquid and connecting it with a string to detect vertical movement. There is a method that takes advantage of the fact that oscillations vary in strength and weakness depending on the distance from the object, and displays this through a separation circuit.

欠点があり、渣た中空筒状の浮子の内面上部に金属片を

を有している。The float of the latter method is made of the metal material with a thickness of 0.1
A thin disk-shaped plate coated with thermoplastic synthetic resin such as polyethylene or polypropylene is used, but it adheres tightly to the ceiling wall of the float chamber due to the surface tension of the liquid. This has the disadvantage that the vertical movement of the float is obstructed, or it becomes inverted or stands upright, making it impossible to operate normally. In order to maintain the correct posture, the float tends to come into close contact with the inner wall surface of the float chamber, which has the disadvantage that the vertical movement of the float is inhibited.

検出用浮子である。The present invention aims to eliminate the above-mentioned drawbacks, and by combining two semicircular spheres made of thermoplastic synthetic resin with a metal substance vapor-deposited on the inner wall to form a sphere, the inner wall can be completely covered. This is a float for detecting the liquid level of a storage battery that operates well and can accurately detect the liquid level by forming a metal thin film body.
本考案の一例を説明する。An example of the present invention will be explained.
第１図に釦ける液面検出装置本体のコイル筒１の下部に

本考案蓄電池液面検出用浮子の構造を示す。The float 3 enters the openwork frame-shaped float chamber 2 provided at the bottom of the coil tube 1 of the liquid level detection device main body shown in Fig. 1, and as the float 3 moves up and down, the metal 2 and 3 show the structure of the float for detecting the liquid level of a storage battery according to the present invention.
ポリエチレン捷たはポリプロピレンなどの熱可塑性合成
樹脂からなる半球４の内壁面に、電気回路の発振の強度

超音波溶着して、第３図に示す如き内壁面の全面に亘っ
て金属薄膜体５が形成された球体６の浮子３としたもの
である。A metal substance such as aluminum, iron, titanium, etc., which changes the intensity of oscillation of an electric circuit, is deposited on the inner wall surface of a hemisphere 4 made of thermoplastic synthetic resin such as polyethylene or polypropylene, and has a thickness of 0.1 mm or less. metal thin film body 5
Two of these are placed facing each other and welded together by heat or ultrasonic welding to form a float 3 of a spherical body 6 with a thin metal film 5 formed over the entire inner wall surface as shown in FIG. It is.
球体６の浮子３を、液面検出装置本体のコイル筒１の下

させる時、蓄電池の振動等により上下が逆転しても作用
能力に変化はなく、又球面上の倒れの点がコイル筒１に
近接したとしても、その作用能力に変りがないことは言
うまでもない。When the float 3 of the spherical body 6 is enclosed in the openwork frame-shaped float chamber 2 located at the bottom of the coil tube 1 of the liquid level detection device main body and operated, even if the top and bottom are reversed due to vibrations of the storage battery, etc., the operating ability will not be affected. There is no change, and it goes without saying that even if the point of inclination on the spherical surface approaches the coil tube 1, there is no change in its operational ability.
而して球体６の浮子３であるが故に、表面張力現象は全
く生じず、天井壁面に密着して上下動が阻害されると云
う懸念もなく順調に作動するのである。Since the float 3 is made of a spherical body 6, no surface tension phenomenon occurs at all, and the float operates smoothly without any concern that it will come into close contact with the ceiling wall surface and inhibit vertical movement.
ところで該浮子３に一定の比重を得たいときは、球体６
の中空の内部に所定の重量物を封入して使用すればよい
。By the way, if you want to obtain a certain specific gravity for the float 3, use the sphere 6.
It can be used by enclosing a predetermined heavy object inside the hollow interior of the container.
上述の如く、本考案蓄電池液面検出用浮子は簡単な構造

めて大なるものである。As mentioned above, the float for detecting the liquid level of a storage battery according to the present invention has a simple structure, but it can detect the liquid level of a storage battery with high accuracy, and by appropriately selecting the specific gravity of the float, it is easy to detect the specific gravity. These detection displays are carried out by electric circuits, and their practical value is extremely great, as remote control becomes possible.
