[0002] A lead-acid battery is a device that stores and releases electrical energy through chemical reactions. Its working principle is mainly based on the electrochemical reaction between lead and lead dioxide (positive electrode) and dilute sulfuric acid (electrolyte). During the use of lead-acid batteries, due to the evaporation of the electrolyte and the consumption of internal chemical reactions, the water content of the electrolyte will gradually decrease and the concentration will gradually decrease. In order to maintain the concentration and amount of the electrolyte, it is necessary to regularly inject an appropriate amount of deionized water or dilute sulfuric acid solution into the battery.

[0027] When the device is in use, the hydraulic rod drives the acid injector 2 to move downward to inject acid into the battery. During this period, the wedge block 302 also moves downward accordingly, and its arc surface pushes the push rod 303 open, driving the collection box 306 to retreat to one side. After the acid injection is completed, the hydraulic rod drives the acid injector 2 to move upward. The rotating cylinder 304 arranged on one side of the machine body 1 rotates under the reaction force of the torsion spring 305, and rotates the collection box 306 fixed on one side of it to the bottom of the acid injector 2. Then, the micro-vibrator 4 at the bottom of the fixed block 301 is started to shake out the residual acid liquid inside the acid injector 2, which falls into the collection box 306 through the guiding plate 310 and finally flows into the liquid collection tank 313 through the elastic collection tube 312, completing the collection of the residual acid liquid.

[0032] A guiding plate 310 is fixedly installed on the top of the collection box 306. The guiding plate 310 is of an inclined structure, which can not only guide the acid liquid into the collection box 306, but also effectively prevent the acid liquid from splashing out of the collection box 306.

[0033] A connecting piece 311 is fixedly installed at the bottom of the collection box 306. The connecting piece 311 includes an upper flange 3111, a lower flange 3112, a sealing strip 3113 and a fixing bolt 3114;

[0034] The upper flange 3111 is fixedly installed at the bottom of the collection box 306. The sealing strip 3113 is fixedly installed at the bottom of the upper flange 3111.
