【考案の詳細な説明】 本考案は蓄電池の比重検出器に関する。[Detailed explanation of the idea] The present invention relates to a specific gravity detector for storage batteries.
鉛蓄電池は充放電によつて電解液比重が変化す
る。放電をすると比重が低下するので過放電を防
止するねらいで、第１図に示すような蓄電池１の
注液栓口２に装着した比重検出器３が提案されて

報などを送るものである。 The float 7 is designed to have a specific gravity value at the overdischarge limit. When the storage battery 1 is overdischarged and the specific gravity of the electrolyte drops below the specific gravity value of the float, the float 7 sinks below the liquid level 9 and the specific gravity detection lead When the switch 6 is approached, the reed switch 6 is closed and an alarm is sent to the outside.
かかる構造であるので、浮子７の径が案内筒５
より当然大きくなり、従つて注液栓口も大きいも
のでなければ使用出来ない欠点があつた。 With this structure, the diameter of the float 7 is equal to the guide tube 5.
Naturally, it is larger, and therefore, the liquid injection tap has the disadvantage that it cannot be used unless it is large.

目的としてなされたものである。 The present invention was developed to eliminate these drawbacks, and can be used even with storage batteries with small liquid injection ports, and the float floats and sinks smoothly, allowing the reed switch to operate reliably and ensuring that the state of the electrolyte is always correct. The purpose of this invention is to provide a storage battery specific gravity detector that can detect the specific gravity of a storage battery.

A hole is made in the cylinder for the electrolyte to enter, and a reed switch for detecting specific gravity is installed vertically in the guide cylinder above the partition, close to the partition so that its axis is on the axis of the guide cylinder, and A rod-shaped permanent magnet is vertically installed in the guide cylinder of the part so that its axis is on the axis of the reed switch for specific gravity detection, and a float with a guide protrusion on the outside and a tapered bottom is arranged.

じない。 In this way, the storage battery specific gravity detector according to the present invention is
The float is placed inside the guide cylinder, and a bar-shaped permanent magnet is used as the permanent magnet, and the permanent magnet is attached vertically to the float so that its axis is on the axis of the reed switch for specific gravity detection. The diameter of the specific gravity detector can be made significantly smaller than that of conventional ones, and it can also be suitably used for storage batteries with small liquid injection plug openings. Also, since a guide protrusion is provided on the outside of the float, which is integrated with the float, the float is guided by the guide protrusion and floats smoothly inside the guide cylinder.
The reed switch can be operated properly at all times. Furthermore, since the bottom of the float is tapered, the gas near the bottom of the float rises along the tapered surface and does not remain attached to the bottom of the float as air bubbles. There is no problem in that excessive buoyancy is applied to the float and prevents accurate operation of the float due to changes in the specific gravity of the electrolyte.

ｂ内には第２図ロに詳示する浮子１７を入れる。 FIGS. 2A and 2B show an embodiment of the present invention, in which specific gravity is detected during charging. In the figure, reference numeral 11 denotes a lead-acid battery having a liquid injection port 12 smaller than that of the storage battery shown in FIG. A specific gravity detector 13 is installed. The dimensions of the collar 14 and the guide barrel 15 are determined so that the lower part of the guide barrel 15 fixed to the collar 14 is located below the liquid level 19. A partition 23 is provided below the guide tube 15, and an appropriate number of small holes 24 are formed in the guide tube 15b below the partition 23 to serve as electrolyte flow holes and gas escape holes. A reed switch 16 for specific gravity detection is vertically buried in the guide tube 15a in the upper part of the partition 23, close to the partition 23, and on the center line of the guide tube 15, with the same axial direction as the guide tube 15. Guide tube 15 below the partition 23

量によつて比重値は任意に設定し得る。 The float 17 has a resin hollow body 21 integrally formed with a guide protrusion 20 on the outside and has a tapered bottom surface 25, and a rod-shaped body 21 that is attached perpendicularly to the hollow body 21 so that its axis is on the axis of the reed switch 16. It consists of a permanent magnet 18 and a weight 22 (preferably lead grains) placed in a hollow body 21. The specific gravity of the float is 1260
Set it to, for example, 1250, which is very slightly lower than (the specific gravity of an automobile battery at the end of charging). The specific gravity value can be arbitrarily set depending on the volume of the float and the weights of the hollow body 21, the rod-shaped permanent magnet 18, and the weight 22.

If the specific gravity of the electrolyte drops below the specific gravity of the float 17, the float 17 will sink, the magnetic force of the magnet 18 will no longer act on the reed switch 16, the reed switch 16 will close, and an alarm (not shown) will be activated. and issue an alarm.
