[0001] The utility model relates to the technical field of battery detection, in particular to a device for detecting the acid filling height of a lead-acid battery. Background Art

[0002] During the production process of lead-acid batteries, acid needs to be injected and the injection height needs to be tested to ensure that the acid content of the battery meets the standard requirements. The original testing method is to measure the acid height of the battery downward with the acid injection port of the battery as the reference surface. Since the bottom area of ​​lead-acid batteries of the same model is the same, the heat sealing depth of the cover of each battery of the same model and the height of each battery tank are different.

[0003] Therefore, it is unreasonable to use the acid injection port of each battery as the detection reference surface. The actual acid content of the battery will be affected by the individual height of each battery, resulting in poor consistency in the total acid content of the battery; thus affecting the overall performance of the battery.

[0029] In order to better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] A device for detecting the acid injection height of lead-acid batteries, as Figure 1 shown, includes a liquid level detection support frame 1, a liquid level detection rod 2 and a working platform 3. The liquid level detection support frame 1 is used as a reference frame for detecting the acid liquid level height in the battery. When detecting a lead-acid battery, the liquid level detection support frame 1 is placed on the working platform 3. The liquid level detection support frame 1 is provided with a plurality of detection ports 11 for detecting the acid liquid level height in the battery. Specifically, the working platform 3 is a horizontal plane, the battery is placed on the working platform 3, and the liquid level detection support frame 1 is also placed on the working platform 3. The detection port 11 of the liquid level detection support frame 1 is aligned with the acid injection port of the battery, and the liquid level detection rod 2 can enter the battery through the detection port 11 to detect the acid liquid level height. In a possible case, the liquid level detection rod 2 is a detection rod provided with a scale.

[0033] As Figure 2 shown, the liquid level detection support frame 1 is provided with a panel 12 and a cavity 13. The panel 12 is used as a reference plane for detecting the acid liquid level height in the battery. The detection port 11 is provided on the panel 12, and the cavity 13 is used to place the battery. Specifically, in this embodiment, the liquid level detection support frame 1 is generally in a "冂" - shaped structure. The panel 12 is the plane of the liquid level detection support frame 1 in the height direction. The "冂" - shaped structure enables a cavity 13 to be formed in the liquid level detection support frame 1 to place the battery. The detection port 11 is provided on the panel 12, and the panel 12 is a horizontal plane parallel to the working platform 3.

[0034] Furthermore, the detection port 11 is a strip-shaped opening. Specifically, in this embodiment, the detection port 11 is roughly an oblong opening, and there are four oblong openings of the same size on the panel 12, arranged in two rows, with two openings in each row aligned. One detection port 11 can align with multiple acid injection ports on the battery, and the liquid level detection rod 2 can move in the strip-shaped opening during the detection process, which is easy to operate and accurate in detection. The length and width of the detection port 11 are roughly 125mm*10mm.

[0035] like Figure 3-4 As shown, the liquid level detection rod 2 includes a handle 21, a first detection end 22, and a second detection end 23. The handle 21 is used for the detection personnel to hold the liquid level detection rod 2, the first detection end 22 is used to detect the upper limit of the acid liquid level, and the first detection end 22 is arranged on the handle 21, and the second detection end 23 is used to detect the lower limit of the acid liquid level, and the second detection end 23 is arranged on the handle 21; specifically, in this embodiment, the handle 21 is roughly cylindrical, and its diameter is roughly 23mm, the first detection end 22 and the second detection end 23 are roughly thin cylinders, and their diameters are roughly 9mm, and the length of the first detection end 22 (as shown in FIG. Figure 4 The length of the second detection end 23 (e.g. Figure 4 The length difference is roughly 4mm, and the height error of the acid solution is roughly ±2mm. It should be noted that, because the acid solution level of the storage battery of different models is different, the length of the first detection end 22 and the second detection end 23 is not limited.

[0036] Furthermore, the first detection end 22 is arranged at one end of the handle portion 21, and the second detection end 23 is arranged at the other end of the handle portion 21; specifically, in the present embodiment, the handle portion 21 is roughly cylindrical, and the cross-sectional area of ​​the handle portion 21 is larger than the detection port 11, and larger than the cross-sectional area of ​​the first detection end 22 and the second detection end 23, and the cross-sectional diameter of the first detection end 22 and the second detection end 23 is smaller than the width of the detection port 11. When the liquid level detection rod 2 detects the battery, the handle portion 21 abuts against the panel 12, and the cross-sectional diameter of the handle portion 21 is larger than the width of the detection port 11.

[0037] The material of the liquid level detection support frame 1 and the liquid level detection rod 2 is PVC (polyvinyl chloride), PP (polypropylene) or other materials that are not corroded by acid and will not bring impurities to the electrolyte, and are not easily deformed.

[0038] Detection method: Place the battery that has completed acid injection on the work platform 3, place the liquid level detection support frame 1 (reference surface) above the battery, align the battery acid injection port with the detection port 11 of the liquid level detection support frame 1, and then use the first detection end 22 of the liquid level detection rod 2 (i.e., the upper limit end of the liquid level) to vertically probe into the acid injection port along the detection port 11 of the liquid level detection support frame 1, loosen the liquid level detection rod 2 for about 2 seconds, take out the liquid level detection rod 2 to observe whether there are traces of liquid on the end face of the first detection end 22, wipe the end face of the detection rod, and continue to measure other acid injection ports. Then use the second detection end 23 of the liquid level detection rod 2 (i.e., the lower limit end of the liquid level) to measure one by one again according to the above method. If there are traces of liquid residue at the first detection end 22 of the liquid level detection rod 2, the liquid level is too high; if there are no traces of liquid residue at the second detection end 23 of the liquid level detection rod 2, the liquid level is too low.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
