Description

[Detailed description of the invention] This invention relates to a storage battery fluid plug (hereinafter simply referred to as a fluid plug).In particular, by accurately indicating when to stop water injection, it is possible to prevent storage battery accidents caused by overfilling with water. The present invention relates to a liquid spout plug as described above.

The lifespan of storage batteries is greatly influenced by the quality of maintenance. Appropriate water replenishment is especially important during these maintenance and inspections; if the battery runs out of fluid, the electrode plates of the storage battery will come into contact with the outside air, causing sulfation, which can lead to a fatal accident in which capacity recovery cannot be expected. For this reason, various liquid reduction display devices such as floats have been devised to prevent the liquid from running out. Among these, the float type has a particularly simple structure and can indicate when to reduce liquid and when to stop water injection, so it is widely applied to liquid outlet plugs. However, because the float attached to the liquid port plug itself is compact, it is often difficult to design it to have sufficient buoyancy due to its dimensions, and when the battery is in use, Stickier substances may adhere or adhere to the side walls of the spout, making its operation inaccurate. As a result, confirmation of when to stop water injection by the float during refilling becomes inaccurate, leading to overfilling, and the electrolyte overflows from the liquid port plug due to the gas generated during charging, often causing serious accidents. For group batteries, various water replenishment devices have been devised that stop the water at a constant liquid level when refilling, but if this principle is applied to a liquid outlet plug, water can be reliably stopped at a constant liquid level. Since it is not possible to secure a sufficient pool inside the liquid spout, if the water injection speed is high, the water will accumulate and overflow from the pool inside the liquid spout. Therefore, an automatic water stop mechanism should be installed on the liquid spout. is difficult.

The present invention eliminates the above-mentioned drawbacks and provides a liquid spout plug that allows confirmation of when to stop water injection even if the float malfunctions.

That is, the present invention provides a storage battery liquid spout in which the upper opening of the liquid spout body is closed with a transparent cap that can be opened and closed. At the same time, two liquid level regulating cylinders are provided in the concave part, which hang down from the concave part to a specified liquid level, and the upper end of one of the liquid level regulating cylinders is opened above the concave part. A float that moves according to changes in the liquid level is inserted into the cylinder, and the upper end of the other liquid level regulating cylinder is opened at the bottom of the concave part, and this liquid level regulating cylinder is used as a water inlet.
In addition, by forming a pool adjacent to the liquid level regulating tube in a part of the concave surface part, and providing a small hole serving as an exhaust port at the bottom of the pool, the water injection stop timing can be adjusted depending on the displacement of the float and The residual water in the pool can be confirmed by the droplets that bubble up.

The present invention will be explained below with reference to an embodiment shown in FIGS. 1 and 2. In FIGS. 1 and 2, reference numeral 1 denotes a liquid spout body, which has a concave structure inside and a concave portion 2 to prevent water from spilling during refilling. 3 and 4 are liquid level regulating tubes that hang down from the concave section 2 provided in the concave section 2 to a specified liquid level; the upper end of the liquid level regulating tube 3 is open above the concave section 2; The upper end of 4 is open at the bottom of concave portion 2 . Further, a float 5 is inserted into the liquid level regulating cylinder 3 and moves up and down according to changes in the liquid level. In addition, the liquid level regulating cylinder 4 serves as a water inlet 6, so it has a sufficiently large inner diameter. Reference numeral 7 denotes a pool formed in a part of the concave surface part 2 adjacent to the liquid level regulating cylinders 3 and 4, in which a part of water remains when replenishing water. Reference numeral 8 denotes an exhaust port provided at the bottom of the pool 7, which consists of a small hole. 9 is the liquid spout body 1
A cap that closes the upper opening of the cap, and is attached to the liquid spout body 1 so that it can be opened and closed freely. Further, the cap 9 is made of a transparent material so that the float 5 can be visually seen through the cap.
10 is a liquid spout body 1 for attaching the cap 9
11 is a packing, and 12 is a storage battery lid.

In this embodiment of the present invention, the timing of water replenishment is determined by visually observing the drop in the float 5 through the cap 9 and confirming the decrease in liquid. In addition, water replenishment is performed by opening the cap 9 when it is confirmed that the liquid has decreased, and dropping water from the top of the water inlet 6 with a water injector such as a kettle while the cap 9 is open. When the battery is dropped, most of the water flows into the storage battery through the liquid level regulating tube 4, but
Some water falls into the pool 7 and flows into the storage battery through the exhaust port 8. At the same time as water flows in, the gas inside the storage battery must be replaced and exhausted to the outside.
In the present invention, when water is injected, the exhaust port 8 is blocked by inflowing water, and the inside of the liquid level regulating tube 4 may be liquid-tight, so it may be difficult to quickly inject the liquid. However, in reality, most of the gas is exhausted through the liquid level regulating tube 3 into which the float 5 is inserted, so even if the water inlet 6 is a little small, the gas in the storage battery can be easily replaced with water, so the water injection rate can be reduced. is not much different from conventional liquid spout plugs. Next, as the water injection progresses, the float 5 in the liquid level regulating cylinder 3 gradually rises as the electrolyte level in the storage battery rises. In this case, if you stop water injection when the float 5 rises to a predetermined position, there is no need to worry about overfilling, but if the float 5 malfunctions, overfilling may occur, and the water refilling period may be delayed. In order to make the battery last longer, people sometimes artificially overfill the battery with water, which results in electrolyte overflowing from the liquid port plug during charging. However, in the embodiment of the present invention, even if excessive water replenishment is continued, when the electrolyte level reaches the lower end of the liquid level regulating tubes 3 and 4, the gas in the storage battery will pass through the liquid level regulating tubes 3 and 4 to the outside. Since the remaining water in the pool 7 above the exhaust port 8 is bubbled vigorously through the exhaust port 8, the phenomenon appears as if the electrolyte has overflowed, and even those with no experience in handling storage batteries may find it difficult to understand. Stop water injection. In this way, in the embodiment of the present invention, even if there is a malfunction in the operation of the float 5, or even if an attempt is made to overfill the pool, a warning is issued by the foam that makes the remaining water in the pool 7 foam. This prevents over-watering.

As mentioned above, the liquid spout of the present invention doubles as a warning when to stop water injection using the float and foam, and prevents over-filling of water.Therefore, it is effective in preventing corrosion of the battery storage box and connections. In addition to being able to contribute, it also has excellent advantages such as being able to prevent serious accidents such as burnout due to leakage.
