[0002] Valve-regulated lead-acid batteries are lean structures, and the electrolyte is stored in the AGM separator. Excessive or insufficient acid content in the battery will directly affect the battery's capacity, low-temperature starting ability, and charging acceptance, causing the battery life to end prematurely. At present, there is no special tooling for valve-regulated lead-acid batteries to detect the battery's saturated acid absorption. Therefore, it is urgent to develop a tooling for measuring the battery's saturated acid absorption for valve-regulated lead-acid batteries. Summary of the invention

[0003] The utility model aims to provide a tool for measuring the saturated acid absorption of a valve-regulated lead-acid battery, which is suitable for fast and accurate measurement of the saturated acid absorption of batteries of different models and different acid addition processes.

[0004] The technical solution of the utility model is: a tool for measuring the saturated acid absorption amount of a valve-regulated lead-acid battery, which is characterized by being composed of a platform, a pulley bracket, a pole group fixing device, a counterweight, a weighing device and a pickling box; wherein the weighing device is arranged on the platform; the pickling box is arranged on the weighing device; the pulley bracket is fixedly connected to the platform; the pole group fixing device and the counterweight are suspended on the pulley of the pulley bracket through a traction rope.

[0005] The pole group fixing device described in the technical solution of the utility model is composed of a bottom plate, a top plate and connecting bolts.

[0006] The bottom plate and the top plate described in the technical solution of the utility model are rectangular plates with the same structure; there are four connecting bolts, which are respectively arranged on the four corners of the rectangular plate.

[0007] The technical solution of the utility model is provided with baffles on two opposite sides of the bottom plate.

[0008] The pulley bracket described in the technical solution of the utility model is composed of a column fixedly connected to the platform, a crossbeam fixedly connected to the top of the column, and two fixed pulleys arranged on the crossbeam.

[0009] One of the two fixed pulleys described in the technical solution of the utility model is located directly above the pickling box, and the other fixed pulley is located above the outer side of the pickling box.

[0010] The platform described in the technical solution of the utility model is provided with steps for placing the weighing device.

[0011] The pulley bracket described in the technical solution of the utility model is arranged on the high step surface of the platform.

[0012] The weighing device described in the technical solution of the utility model is an electronic scale.

[0013] The counterweight described in the technical solution of the utility model matches the pole group fixing device equipped with the pole group.

Before the fixing device enters the acid soaking box, weigh the acid soaking box and sulfuric acid and record the first weight data. After the pole group fixing device is completely put into the acid soaking box, observe the reaction state of the pole group and the solution and the change of the electronic scale data. When the bubbles generated on the surface of the acid solution change from strong to weak and the bubbles stop, the weighing device data also stops changing at this moment. Slowly pull the pole group fixing device out of the acid soaking box. When the pole group no longer drips acid downward, weigh the acid soaking box and sulfuric acid and record the second weight data. Subtract the second weight data from the first weight data to get the saturated acid absorption of the pole group. The saturation of each battery with the same structure is calculated based on the saturated acid absorption of the battery.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1As shown, an embodiment of a tooling for measuring the saturated acid absorption amount of a valve-regulated lead-acid battery of the utility model is composed of a platform 1, a pulley bracket 2, a pole group fixing device 3, a counterweight 4, a weighing device 5 and a pickling box 6.

[0021] The platform 1 is the base of the device, which is rectangular and has steps. The steps match the weighing device 5, which is placed on the low step surface of the steps, and the top surface of the weighing device 5 is flush with the high step surface of the steps, giving a sense of an integral base.

[0022] The weighing device 5 is an electronic scale.

[0023] The pickling box 6 is placed on the electronic scale. The pickling box 6 is a rectangular box body, and its volume is larger than the volume of the pole group after the pole group fixing device 3 is loaded with the pole group. The pickling box 6 is filled with sulfuric acid.

[0024] The pulley bracket 2 is composed of a column fixedly connected to the middle of the high step surface of the platform 1, a beam fixedly connected to the top of the column, and two fixed pulleys arranged on the beam. One of the two fixed pulleys is located directly above the pickling box 6, and the other fixed pulley is located above the outside of the pickling box 6.

[0025] The pole group fixing device 3 is composed of a bottom plate, a top plate and connecting bolts. The bottom plate and the top plate are rectangular plates with the same structure, and there are four connecting bolts, which are respectively arranged at the four corners of the rectangular plate. Baffles are respectively arranged on two opposite sides of the bottom plate. The pole group fixing device 3 can lock pole groups of different specifications and can press them to the thickness of the corresponding pole group.

[0026] The counterweight 4 matches the pole group fixing device 3 equipped with the pole group. The pole group fixing device 3 and the counterweight 4 are suspended on two fixed pulleys of the pulley bracket 2 through a traction rope.

[0027] The measurement steps include:

[0028] (1) Place the electronic scale on the low surface of the weighing platform 1;

[0029] (2) Place the pickling box 6 containing the sulfuric acid solution on an electronic scale and record the weight of the sulfuric acid weighed at this time①; adjust the electrode group fixing device 3 to lock it to the thickness of the corresponding electrode group;

[0030] (3) Place the electrode group to be tested and the counterweight 4 on the two fixed pulleys of the pulley bracket 2, slowly and smoothly put them into the acid soaking box 6, and the electrode group needs to be completely immersed in the sulfuric acid solution;

[0031] (4) Observe the reaction state between the electrode group and the solution and the changes in the electronic scale data. When the bubbles generated on the surface of the acid solution turn from strong to weak and stop, and the data on the electronic scale 5 also stops changing, slowly pull the electrode group to be tested out of the acid immersion box 6. When the electrode group no longer drips acid downward, record the weight displayed on the electronic scale 5 at this time②;

[0032] (5) The saturated acid absorption capacity of the electrode group is obtained by subtracting the weight of sulfuric acid in the pickling box after immersion from the weight of sulfuric acid weighed before immersion①.

[0033] The utility model can quickly and accurately measure the saturated acid absorption of any newly developed battery model or the same model battery with a changed internal pole group structure, and calculate the saturation of each battery with the same structure based on the saturated acid absorption of the battery.

[0034] The utility model can also accurately and quickly measure the saturated acid absorption of the pole group before entering the tank, and can also verify the saturated acid absorption of the pole group after acid addition at different vacuum degrees, different acid addition times, and different acid addition times.
