Description

[Detailed explanation of the idea] The present invention relates to a sealed bulk liquid injection device for storage batteries.

Conventionally, in this type of liquid injection device, the faster the flow rate of refill water through the supply pipe, the higher the pressure that hits the cylinder, which is an extension above the specified cylinder, and the upstream side of the cylinder is pressurized and the downstream side is in a depressurized state. Therefore, the level of the fluid increases on the upstream side of the cylinder and decreases on the downstream side, and this tendency increases as the velocity of the fluid increases, for example, as the water level of the supply source increases.

In this case, the flow of replenishing water hits the cylinder and enters the inside of the cylinder from the upper end along the cylinder, displacing and eliminating the necessary air in the cylinder, and as a result, the operation of the liquid level regulating pipe becomes unreliable. If the water level decreases or becomes higher, the liquid that has entered the cylinder inner diameter may become blocked by the liquid that has entered the pipe, causing a delay in water replenishment, or in extreme cases, the liquid level may not reach the specified level. Replenishment of water often stopped.

The present invention provides a liquid injection device that improves the shortcomings of the conventional devices of this kind, and includes a plurality of storage batteries 1 each having a liquid level regulating cylinder 2. Supply pipe 3...
In a sealed bulk liquid injection device for storage batteries through which liquid is injected all at once, the liquid injection port 8 of the storage battery 1 is connected to the liquid injection port 8 of the storage battery 1.
An air chamber 4 is formed inside, and the supply pipe 3 is opened on the peripheral side wall.
, 3, a tubular connection part 11.11 for connection is provided protrudingly provided, and a cylindrical part 9 for attachment is protruded from the lower surface, and a liquid filling stopper 12 is attached with the cylindrical part 9 for attachment. 2 is inserted through the liquid injection port 8 and extended upward, and the upward extension cylinder part 5 faces into the air chamber 4 of the liquid injection tap 12, and the extension cylinder part 5 is inserted into the air chamber 4. A fine gap 6 is created between the air chamber 4 and the inner wall of the air chamber 4, and a baffle plate 7 is inserted.

In the attached drawings showing an example of the implementation of the present invention, the liquid spout 12
has a cylindrical shape, and has a cylindrical connection part 11.11 projecting from the left and right opposing parts of its circumferential side wall, and a mounting cylinder part 9 protruding from the lower surface thereof has a cylindrical connection part 11. It was shaped like a screw head provided with a thread, and was thereby screwed onto a spiral-shaped liquid injection port 8 provided with a thread on the inner periphery provided on the top wall of the storage battery 1.

A circular annular baffle plate 7 extending horizontally is provided protruding from the outer periphery of the upwardly extending cylindrical portion 5 of the liquid level regulating cylinder 2, and a minute gap is formed between the periphery of the baffle plate 7 and the inner peripheral side wall surface of the air chamber 4. 6 was a small gap of several mm.

The baffle plate 7 may be made to protrude from the inner circumferential wall of the air chamber 4.

A small hole 1 for liquid injection is formed in the mounting cylindrical part 9 at the lower part of the liquid injection stopper 12, which vertically penetrates the wall surrounding the outer periphery of the liquid level regulating cylinder 2.
One pair of 0 was provided.

The other ends of the supply pipes 3, 3 connected to the connection parts 11.11 on both sides of the liquid injection tap 12 are connected to the storage batteries 1 on both sides of the storage battery 1.
, 1 with the device of the present invention 11゜11
Similarly, a predetermined number of storage batteries are connected to each other by a supply pipe.

In this device, if water replenishment is carried out according to the usual method, running water will enter the battery 1 through the small holes 10, and the air inside the battery 1 will be removed through the micro gaps 6, The baffle plate 7 obstructs the rise of the flowing water and prevents the water from entering the air chamber 4, especially into the upper extension 5, thereby ensuring stable water replenishment without clogging the upper extension. The work is carried out smoothly, the electrolyte level closes the lower end of the liquid level regulating cylinder 2 due to water replenishment, the exhaust stops, and the liquid injection also stops automatically.

In this way, a required amount of air is stored in the defined tube 2 including the upper extension portion 5 of the air chamber 4, and the liquid level is maintained at a predetermined water level.

In this way, according to the present invention, since the baffle plate 7 is provided with a fine gap 6 between the air chamber 4 and the upper extension part 5,
The flow of water during water refilling (liquid) is prevented from rising and entering into the upper extension part 5, and relatively quick and smooth water refilling work can be performed, and water injection is performed at a predetermined electrolyte level. This has the effect of making it possible to stop the engine more reliably.
