The driving mechanism rotates to drive the injection mechanism to move downward to inject water into the new energy lead-acid battery, thereby achieving water replenishment for the new energy lead-acid battery.

[0004] However, the above-mentioned prior art solutions still have shortcomings: 1. The water replenishment efficiency for multiple lead-acid batteries that need water replenishment is low, that is, the time taken to load and unload the multiple lead-acid batteries for water replenishment is relatively long, resulting in low water replenishment efficiency; 2. After water replenishment, the residual water in the intubation tube is easy to spill, and the water contains acid, which is easy to pollute or corrode the batteries or the surrounding environment.

[0005] To this end, the utility model provides a lead-acid battery water replenishing device. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a lead-acid battery water replenishing device, including a base 1, a water storage tank 2 and a water injection pipe 3. The water storage tank 2 stores water that needs to be replenished. Two support plates 11 are fixedly connected to the top of the base 1, and a turnover tube 4 is rotatably connected between the two support plates 11. Specifically, one end of the turnover tube 4 is fixedly connected to a support shaft 41, and the other end is fixedly connected to a transfer tube 42. Positioning holes rotatably connected to the support shaft 41 and the transfer tube 42 are respectively opened on the tops of the two support plates 11. A control motor 9 is fixedly connected to one side of one of the support plates 11. The output shaft of the control motor 9 is fixedly connected to the support shaft 41, and the control motor 9 provides driving force for the rotation of the turnover tube 4.

[0024] The outer peripheral wall of the circulation tube 4 is fixedly connected with a plurality of water outlet pipes 5 arranged along the axial direction. The number of the water outlet pipes 5 is determined according to the water filling port of the lead-acid battery. The free end of the water outlet pipe 5 is fixedly connected to the middle of the water injection pipe 3. The axis of the water injection pipe 3 is perpendicular to the axis of the water outlet pipe 5 and the circulation tube 4. Axial pressing valves 6 are arranged at both ends of the water injection pipe 3. The function of the axial pressing valve 6 is to dock with the water filling port of the lead-acid battery. When the circulation tube 4 rotates, it will drive the axial pressing valve 6 to change the injection position. A trigger assembly 7 is arranged between the axial pressing valve 6 and the support plate 11. When the axial pressing valve 6 is inserted into the above-mentioned water filling port, the trigger assembly 7 will trigger the axial pressing valve 6 to open, and then the battery will be filled with water.

[0025] The height of the water tank 2 is higher than the circulation tube 4 and the two are connected by a pipeline. Specifically, the top of the base 1 is fixedly provided with a support leg 12 located on one side of another support plate 11, and the water tank 2 is fixedly provided on the top of the support leg 12. The bottom of the water tank 2 is fixedly connected with a downpipe 21 rotatably connected to the transfer tube 42. The water in the water tank 2 enters the circulation tube 4 and is then injected into the lead-acid battery through each axial pressing valve 6. The top of the base 1 is provided with a battery placement groove 13 located on both sides of the circulation tube 4, and the function of the battery placement groove 13 is to position the lead-acid battery.

[0026] Furthermore, the top of the water storage tank 2 is connected to a pressure tank 8 through a pipeline. The pressure tank 8 stores gas with a certain pressure. The pressure tank 8 applies air pressure to the water storage tank 2 through the gas. This arrangement can ensure that several water injection pipes 3 can smoothly supply water to the axial press valve 6, thereby ensuring the flow rate of water discharged by the axial press valve 6.

[0027] The above-mentioned axial pressure valve 6 includes a plug 61, a transmission shaft 62 and a sealing disk 63. One end of the plug 61 is sleeved in the end of the water injection pipe 3 and is axially slidably matched. A sealing sleeve is arranged between the plug 61 and the water injection pipe 3 to achieve sealing fit. The transmission shaft 62 passes through the plug 61 in a gap and one end of the transmission shaft is fixedly connected to a sealing disk 63 opposite to the other end of the plug 61. The gap between the transmission shaft 62 and the plug 61 is a water passage. When the sealing disk 63 contacts the plug 61, the above-mentioned water passage is blocked, otherwise it is opened. The plug 61 is a component directly plugged into the battery water filling port, and the other end of the transmission shaft 62 is fixedly connected to the inner circumferential wall of the water injection pipe 3 through a connecting rod 621.

[0028] Furthermore, the other end of the insert tube 61 is conical, and the conical structure facilitates the insert tube 61 to be inserted into the water supply port of the battery. A sealing pad 631 is bonded to one side of the sealing disk 63 .

[0029] The trigger assembly 7 includes a pressure plate 71, a return spring 72 and a stop shaft 73. The outer peripheral wall of the insert tube 61 is fixedly connected to one end of the pressure plate 71. The outer peripheral wall of the water outlet pipe 5 is fixedly connected to a guide shaft 51 that is slidably matched with the pressure plate 71. Specifically, a guide hole that is slidably matched with the guide shaft 51 is opened on one side of the pressure plate 71. The guide shaft 51 is sleeved with a return spring 72 located between the water outlet pipe 5 and the pressure plate 71. The function of the return spring 72 is to provide elastic force for the insert tube 61 to move outward through the pressure plate 71. The two sides of the two support plates 11 are respectively connected to the stop shaft 73 used in conjunction with the pressure plate 71 through the support plate 111. There are two stop shafts 73, which are respectively located above the two battery placement slots 13. When the pressure plate 71 touches the stop shaft 73, it will drive the insert tube 61 away from the sealing rubber pad 631 on the sealing disk 63. At this time, the axial pressing valve 6 is opened to drain water outward.

[0030] When using the device, first place two lead-acid batteries to be filled with water in the battery placement slot 13, then start the control motor 9, the support shaft 41 drives the circulation tube 4 to rotate, and the axial pressing valve 6 at one end of the water injection pipe 3 is close to one of the batteries. When the plug 61 on the axial pressing valve 6 is inserted into the water filling port on the battery and in the process of continuous entry, the pressure plate 71 will touch the stop shaft 73, and the pressure plate 71 drives the plug 61 to move axially relative to the water injection pipe 3, and the plug 61 is away from the sealing pad 631. The air pressure in the pressure tank 8 will push the water in the water storage tank 2 to be transported into the circulation tube 4, and then injected into the battery through the plug 61 corresponding to each water injection pipe 3. After the current lead-acid battery is filled with water, the control circulation tube 4 is reversed. When the plug 61 is separated from the water filling port, the reset spring 72 resets and pushes the plug 61 to re-squeeze the sealing pad 631, and the current axial pressing valve 6 is blocked to prevent the water in it from spilling. In this way, the reversed circulation tube 4 will replenish water for another lead-acid battery.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
