Description

Technical Field

[0001] The utility model relates to the technical field of battery detection, in particular to a battery electrolyte leakage detection tool. Background Art

[0002] The electrolyte of lead-acid batteries is dilute sulfuric acid prepared by mixing chemically pure sulfuric acid and deionized water in a certain proportion. When the electrolyte in the battery is insufficient, the negative plate is directly in contact with the air, causing oxidation of the plate, further generating irreversible sulfate and reducing the service life. At the same time, when there is too much electrolyte inside the battery, under the actual working conditions of the car (such as vibration, tilt, instantaneous high current charging, etc.), the electrolyte will leak from the exhaust hole and corrode the car body and other equipment. For this reason, all automobile OEMs require the completion of certification tests related to electrolyte leakage for lead-acid batteries, especially AGM type batteries.

[0003] AGM lead-acid batteries mainly use oxygen recombination to achieve maintenance-freeness. The main design feature is to strictly control the internal saturation of the battery within the range of 93% to 97%. Within this range, the electrolyte is completely adsorbed on the AGM separator, and there is no flowing electrolyte, so there is no risk of leakage.

[0004] However, since the performance of this type of battery is closely related to the amount of electrolyte, as automobile OEMs have higher requirements for battery performance, each battery manufacturer wants to increase the amount of electrolyte inside the battery, which can easily cause the battery to leak during actual use. For this reason, when each OEM actually conducts an electrolyte leakage test on AGM batteries, it is required to drill holes on each single grid side of the long side of the battery to determine whether there is free acid inside the battery. If free acid exists, it is considered that there is a risk of electrolyte leakage and it is directly identified as an unqualified product.

[0005] The patent document with application number CN202020361744.7 and titled "A tool for detecting electrolyte leakage of an AGM battery" discloses an AGM battery electrolyte leakage detection tool that can collect free acid in the battery body, can realize the function of tilting and standing the battery at a predetermined angle and identifying the acid leakage. The tilt angle of the AGM battery to be tested is controlled to be 5°C to 70°C by sliding the support rod on the upper floor. The platform and the support plate form an inclined frame to realize the tilted and stationary state of the AGM battery to be tested. The acid box is placed on the underground floor, below the protective baffle. The acid box is inclined inside to facilitate the collection of overflowing free acid.

[0006] After the battery is placed on the support plate, a protective baffle is set to block the battery in order to stabilize the battery on the support plate. When testing the battery, it is necessary to drill holes on each single grid side of the long side of the battery. When drilling, it is necessary to pay attention to staggering the position of the protective baffle. If the holes on each single grid side of the long side of the battery correspond to the protective baffle, the protective baffle will easily block the holes on each single grid side of the long side of the battery, resulting in inaccurate test results. When free acid is discharged from the inside of the battery, it will adhere to the outside of the battery plastic shell. After the test is completed, it is inconvenient to wipe the acid attached to the battery plastic shell due to the obstruction of the protective baffle. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0039] Example 1: Reference Figure 1-Figure 3 As shown, a battery 9 electrolyte leakage detection tool comprises a bottom plate 1, one end of which is elastically rotatably connected to an inclined plate 2. Specifically, an ear plate 12 is fixed to the lower end of the inclined plate 2, and the ear plate 12 is rotatably connected to the bottom plate 1 through a pin 13, and a torsion spring is sleeved on the pin 13, one end of the torsion spring is fixedly connected to the bottom plate 1, and the other end of the torsion spring is fixedly connected to the ear plate 12.

[0040] The inclined plate 2 and the bottom plate 1 are both made of engineering plastics, so the inclined plate 2 and the bottom plate 1 have strong corrosion resistance.

[0041] An angle adjustment assembly is provided between the inclined plate 2 and the bottom plate 1. A fixed plate 4 is fixed to the upper end of the bottom plate 1, a screw 5 is threadedly connected to the fixed plate 4, the axial direction of the screw 5 is perpendicular to the axial direction of the pin 13, a wedge block 3 is provided between the inclined plate 2 and the bottom plate 1, the lower end of the wedge block 3 is in sliding contact with the upper end of the bottom plate 1, the upper end of the wedge block 3 is in sliding contact with the lower end of the inclined plate 2, and the screw 5 is rotatably connected to the wedge block 3.

[0042] Reference Figure 3 As shown, by rotating the screw rod 5, the screw rod 5 can drive the wedge block 3 to move in the length direction of the screw rod 5. When the wedge block 3 moves to the left, the angle between the inclined plate 2 and the bottom plate 1 increases. When the wedge block 3 moves to the right, the angle between the inclined plate 2 and the bottom plate 1 decreases.

[0043] A rotating rod 6 is fixed to the upper end of the inclined plate 2, and the rotating rod 6 is perpendicular to the inclined plate 2. The upper end of the rotating rod 6 is rotatably connected to a support rod 7, and the support rod 7 is perpendicular to the rotating rod 6. The end of the support rod 7 away from the rotating rod 6 is rotatably connected to a blocking rod 8, and the blocking rod 8 is perpendicular to the support rod 7. The battery 9 is located on the inclined plate 2, and the blocking rod 8 blocks the upper end of the battery 9.

[0044] Reference Figure 1-Figure 3 As shown, the battery 9 is located on the inclined plate 2, and then the upper left side of the battery 9 is blocked by the blocking rod 8. In order to ensure the stability of the battery 9 after being blocked by the blocking rod 8, the blocking rod 8 blocks the middle part of the upper left side of the battery 9.

[0045] The battery 9 on the inclined plate 2 is blocked by the cooperation of the rotating rod 6, the supporting rod 7 and the blocking rod 8 on the inclined plate 2, and can be applicable to batteries 9 of different specifications.

[0046] The battery 9 is partially located outside the inclined plate 2 , a lower plate 10 is fixed to the lower end of the bottom plate 1 , a slot is provided on the lower plate 10 , an acid box 11 is located in the slot, and the acid box 11 is located below the battery 9 outside the inclined plate 2 .

If there is free acid in the storage battery 9, the free acid in the storage battery 9 can flow out through the drilled holes of each single grid edge on one side of the long side of the storage battery 9 and enter the acid box 11. If free acid is discharged from the drilled hole, it proves that the storage battery 9 is unqualified.

[0053] After the storage battery 9 is placed on the inclined plate 2, the center of the storage battery 9 and the axis of the inclined plate 2 in the length direction have an intersection. After the subsequent blocking rod 8 blocks the upper left end of the storage battery 9, the storage battery 9 can be prevented from rotating around the axis of the blocking rod 8 and tilting. If there is free acid in a single cell of the storage battery 9, the free acid in the single cell can be effectively discharged. The accuracy of the test result is guaranteed. At the same time, it can be ensured that the free acid discharged from the inside of the storage battery 9 can be discharged into the acid box 11.
