Description

[Detailed Description of the Invention] The present invention relates to an improvement in a storage battery injection device that automatically injects electrolyte into the storage battery so that the electrolyte level reaches a specified level.

Conventionally, electrolyte was injected into a storage battery tank by detecting the level of the electrolyte by looking through a liquid level indicator installed below the fill port on the lid of the battery tank. . Therefore, in a collective storage battery consisting of multiple cells, it is extremely complicated to remove the liquid port plug for each cell, inject liquid, and check the specified liquid level. Was. To this end, we have recently begun connecting the liquid filling valves of each cell with connecting pipes laid in the direction of the cell array, and automatically supplying liquid from the liquid storage tank connected to one end of the connecting pipe to each cell tank. A so-called simultaneous bulk injection device that injects liquid simultaneously is employed. In such a liquid injection device, it is necessary to detect whether or not it is necessary to inject electrolyte into the battery container, or to know whether the required amount of liquid is being poured satisfactorily into each battery container. It is also necessary to check the electrolyte level in the battery. However, even with the above-mentioned liquid injection device, there is a drawback that the level of the electrolyte in the battery container cannot be easily observed and confirmed.

In view of the above-mentioned drawbacks, the present invention provides a storage battery injection device that allows the level of the electrolyte in the battery container to be easily checked.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In Figures 1 and 2, 1 is an electrolytic solution 2
1A is the lid of this battery case. Reference numeral 3 denotes a liquid injection tap main body made of a transparent synthetic resin which is screwed onto the lid, 3a is an exhaust hole, and the inside of the liquid injection tap main body 3 is partitioned into a liquid replacement chamber 4 and a liquid level indicator chamber 5 by a partition plate 3A. ing. Reference numeral 6 denotes a liquid supply pipe that passes through a part of the liquid level indicator chamber 5 in the horizontal direction, and one end thereof communicates with the lower part of a liquid storage tank (not shown) via a socket, and 7 is directly below the part of this liquid supply pipe 6. This is a fluid replacement tube introduced into the fluid replacement chamber 4. Reference numeral 8 denotes a tube projecting from the bottom of the liquid injection tap main body 3, that is, from the bottom of the liquid replacement chamber 4 into the liquid replacement chamber. A small hole forming a gate 9 is provided. Reference numeral 10 denotes a valve body which is inserted into the tube body concentrically with the tube body 8, and whose conical portion 10A provided on the upper end side opens and closes the liquid injection gate 9 so as to face the inclined upper inner wall of the tube body 8. A space 11 between the valve body 10 and the pipe body 8 forms a liquid injection chamber. Reference numeral 12 denotes a liquid level indicator rod that loosely penetrates the bottom plate and partition plate 3A of the liquid filler body 3, 13 a buoy attached to the lower end of this liquid level indicator stick and floating on the electrolyte surface, and 14 the liquid level indicator rod 12. This is a liquid level indicator fixed to the upper end of the liquid level indicator and disposed inside the liquid level indicator chamber 5.
Reference numeral 15 denotes a stopper attached to the lower side surface of the liquid level indicator rod 12. Reference numeral 16 denotes a valve control rod which is rotatably provided with one end pivotally supported by a support stopper 17 which is provided downwardly protruding from the bottom of the liquid injection tap main body 3. An engagement frame portion 10B provided on the lower end side of the valve body 10 is loosely fitted. Valve control rod 16
The distal end side is a U-shaped or frame-shaped engaging portion 16a, and this engaging portion is loosely fitted into a portion of the liquid level indicator rod 12 above the portion where the stopper 15 is attached.

Next, the operation of the liquid injection device having the above configuration will be explained. First, visually check the height position of the liquid level indicator 14 in the liquid level indicator chamber 5, and as shown in FIG. When you sense that your body is in a state where you need fluid replacement,
By opening a pot provided between a liquid storage tank (not shown) and the liquid supply pipe 6, the liquid sent from the liquid storage tank through the liquid supply pipe 6 flows through the liquid replacement pipe 7 and enters the liquid replacement chamber 4. Fill it up. On the other hand, the buoy 13 floating on the surface of the electrolytic solution 2 is at a low position because the liquid level is low, and the liquid level indicator 12 is downward. Therefore, the valve control rod 16, which loosely engages with the liquid level indicator rod 12 at the engaging portion 16a, rotates clockwise in the drawing until a portion of the engaging portion 16a contacts the stopper 15, and the valve body 10 is pulled down, and the liquid injection gate 9 is open. Therefore, the liquid filling the liquid replacement chamber 4 flows down through the liquid injection chamber 11 through the liquid injection gate 9 and onto the liquid surface of the electrolytic solution 2. As the liquid level of the electrolytic solution 2 gradually rises due to this injection and approaches the upper limit specified liquid level B shown in FIG. 2, the liquid level indicator 12 also rises as the buoy 13 rises. The rise of the liquid level indicator 14 at the upper end can be clearly seen from above the liquid level indicator chamber 5. As the liquid injection continues and the liquid level of electrolytic solution 2 reaches the upper limit specified liquid level B,
As shown in FIG. 2, the stopper 15 is connected to the valve control rod 1.
Push up the tip of No.6. As a result, the valve body 10 is pushed up, the liquid injection gate 9 is closed, and the injection of liquid into the battery container 1 is automatically stopped. At this time, it can be easily confirmed from the top surface of the liquid filler that the liquid level indicator 14 in the liquid level indicator chamber 5 is located at a predetermined height corresponding to the upper limit specified liquid level, and by this visual confirmation, the inside of the battery container 1 can be easily confirmed. The electrolyte level can be easily detected.

As described above, in the liquid injection device of the present invention, the battery container 1
The required injection into the container is automatically performed.

As described above, the storage battery injection device according to the present invention includes a liquid level indicator chamber inside the liquid injection stopper whose inside can be seen through from the top surface, and a liquid supply pipe connected to the liquid storage tank that supplies fluid through the replenishment pipe. A liquid replenishment chamber is formed, and a liquid injection chamber whose lower end side opens into the battery container and whose upper end side communicates with the liquid replenishment chamber via a liquid injection gate that can be opened and closed by a valve body, It is movable up and down in the battery container, the upper end serves as a liquid level indicator and is located in the liquid level indicator chamber, and the lower end is provided with a stopper, and the lower end is connected to a buoy floating on the electrolyte level in the battery container. a liquid level indicator rod, one end of which is rotatably supported at the lower part of the liquid filling tap, the other end of which is loosely fitted into a portion of the liquid level indicator above the stopper, and the valve body is in the middle portion. and an engaged valve control rod. The valve body is moved up and down via the valve control rod by the vertical movement of the liquid level indicator rod in accordance with the rise or fall of the buoy to a predetermined position, thereby controlling the opening and closing of the liquid injection gate. It has been done.

Therefore, according to the liquid injection device of the present invention, by visually checking the height position of the liquid level indicator in the liquid level indicator chamber that can be easily seen from the top surface of the liquid injection stopper, the electrolyte in the battery container can be measured. The face position can be detected very easily. Furthermore, according to the present invention, not only can the electrolyte be automatically injected so that the electrolyte level in the battery container reaches a predetermined level in response to a drop in the level of the electrolyte in the container, but also Stopping is accomplished by rotating the valve control rod and moving the valve body up and down in response to the vertical movement of the liquid level indicator rod connected to the buoy, which opens and closes the liquid injection gate of the liquid injection tap. This has the advantage that the liquid injection can be stopped reliably. Therefore, the liquid injection device of the present invention can be applied to each cell to easily check the liquid level of each cell even when liquid is injected into a large number of cells constituting a collective storage battery at once. In addition, the required liquid injection can be performed easily.
