Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery maintenance, and more specifically, it relates to a lead-acid battery repair device for communication base stations. Background Art

[0002] In communication base stations, lead-acid batteries, as backup power supplies, can continue to supply power to network devices during power outages to ensure that communication devices can continue to operate and maintain the continuity of communication services when the mains power is interrupted;

[0003] In communication base stations, the service life of lead-acid battery packs is usually about five to six years. When lead-acid batteries are over-discharged or left for a long time after discharge, their battery capacity decreases. In order to ensure the normal operation of communication base stations, lead-acid batteries need to be repaired regularly;

[0004] Although existing repair methods such as deep charge and discharge, adding repair fluid, or charging with a large voltage can activate the active substances inside lead-acid batteries to a certain extent and help improve the power storage capacity of lead-acid batteries, for lead-acid batteries with severe sulfation, the above repair methods are difficult to completely eliminate the sulfation phenomenon, resulting in a limited degree of recovery of the lead-acid battery capacity.

At the same time, since the annular frame is always subjected to the thrust of the piston plate, it can be ensured that the end of the liquid extraction pipe far from the end cover always presses against the filter screen, so that the lower end of the liquid extraction pipe is always immersed in the electrolyte, thereby realizing the effective suction of the electrolyte and avoiding incomplete liquid extraction caused by partial retention of the electrolyte;

Detailed implementation manners

[0049] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0050] Please refer to Figure 1 , there is a conventional lead-acid battery 100 for communication base stations. Inside it, a number of mutually independent single cells 120 are separated by a partition 110. A number of groups of plates 130 electrically connected to the corresponding electrodes 170 are provided in each single cell 120. A filter screen 140 is provided above the plates 130. A liquid extraction port 150 and a water injection port 160 are provided at the upper end of each group of single cells 120.

[0051] Please refer to Figure 2 and Figure 3 , the present invention discloses a lead-acid battery repair device for communication base stations, including a base 200, a repair table 300, a liquid extraction unit 400, and a water injection and repair unit 500;

[0052] A horizontal driving member 210 is provided on the abutment 200; the repair table 300 includes a support table 310 connected to the horizontal driving member 210 and a tooling table 320 movably arranged on the support table 310, and the tooling table 320 is used for assembling the lead-acid battery 100;

[0053] Please refer to Figure 4 、 Figure 5 and Figure 6 , the liquid pumping unit 400 is arranged above the tooling table 320, and includes a mounting plate 410 fixedly connected to the tooling table 320, a liquid pumping plate 440 liftably arranged on the mounting plate 410, and several groups of liquid pumping members 450 arranged on the liquid pumping plate 440. The liquid pumping members 450 correspond to the liquid pumping ports 150 one by one. The liquid pumping member 450 includes an end cover 451 detachably mounted on the liquid pumping plate 440 and a liquid pumping pipe 452 movably arranged in the end cover 451. A suction channel 454 is formed in the liquid pumping pipe 452;

[0054] Please refer to Figure 2 and Figure 3 , the water injection and repair unit 500 includes a support frame 510 fixed to the abutment 200, a transverse moving member 520 arranged on the support frame 510, and a lifting member 530 connected to the transverse moving member 520. Several groups of water injection members 540 and charging posts 550 are arranged on the lifting member 530.

[0055] Specifically, after the lead-acid battery 100 for a communication base station to be repaired is completely discharged, it is assembled onto the tooling table 320. The plugs of each liquid pumping port 150 are pulled out, and the liquid pumping plate 440 is driven downward to drive each liquid pumping member 450 to move downward synchronously until the liquid pumping pipe 452 is inserted into the corresponding single cell 120 through the corresponding liquid pumping port 150, and the end cover 451 seals the liquid pumping port 150. At the same time, the bottom of the liquid pumping pipe 452 contacts the filter screen 140 in the single cell 120, and then the electrolyte in the single cell 120 can be sucked out through the suction channel 454 of the liquid pumping pipe 452; during the process of sucking the electrolyte, the tooling table 320 is flipped to drive the lead-acid battery 100 to gradually tilt to one side, so that the electrolyte in the single cell 120 gradually accumulates on one side, and at the same time, the liquid pumping pipe 452 also deflects towards the normal direction and always contacts the filter screen 140 until the electrolyte is completely pumped out;

[0056] After the electrolyte is completely sucked out, the liquid suction member 450 is removed from the corresponding cell 120. The water injection member 540 and the charging column 550 are driven by the transverse movement member 520 to move above the lead-acid battery 100, so that the water injection member 540 is aligned with the corresponding water injection port 160, and the charging column 550 is aligned with the corresponding electrode 170. Then, the water injection member 540 and the charging column 550 are driven by the lifting member 530 to descend until the charging column 550 is electrically connected to the corresponding electrode 170. At the same time, the water injection member 540 is inserted into the corresponding water injection port 160, and distilled water is injected into the corresponding cell 120 through the water injection member 540. After the injection is completed, the charging column 550 is powered on, and the lead-acid battery 100 is charged with a small current (a current below the 20h rate) until the voltage is stable, and then the distilled water in the cell is drained; the above-mentioned water injection and drainage steps are repeated multiple times until the battery capacity of the lead-acid battery 100 is restored to the required level; after the lead-acid battery 100 is repaired, the distilled water is completely poured out, and then the electrolyte is added again.

[0057] It should be noted that in the above repair process, the solubility product of sulfate is increased by reducing the acid solution density, and a small current is used for a long time to charge to reduce the ohmic polarization and delay the premature appearance of the water decomposition voltage. Eventually, the sulfation phenomenon is gradually reduced or eliminated during the dissolution and conversion into active substances. By repeatedly charging and discharging, the sulfation phenomenon is eliminated, thereby effectively restoring the battery capacity.

[0058] In one embodiment, please refer to Figure 4 and Figure 5 , the pumping unit 400 further includes a lifting platform 420 that is liftably arranged on the mounting plate 410. A lifting cylinder 430 for driving the lifting platform 420 is fixed on the mounting plate 410. The pumping plate 440 is mounted on the lifting platform 420, and the pumping member 450 is located directly above the corresponding pumping port 150;

[0059] Specifically, by driving the lifting platform 420 to descend by the lifting cylinder 430, the pumping plate 440 and the pumping member 450 can be driven to move downward synchronously until the pumping member 450 is inserted into the corresponding pumping port 150.

[0060] Furthermore, a liquid storage cylinder 460 is further arranged on the lifting platform 420. The lower end of the liquid storage cylinder 460 is communicated with each pumping member 450 on the pumping plate 440 through a liquid delivery pipe 470, and the upper end of the liquid storage cylinder 460 is connected with a liquid pump 480;

[0061] Specifically, when the liquid pump 480 is turned on, a negative pressure is generated in the liquid storage cylinder 460, and the electrolyte in each cell 120 can enter the liquid storage cylinder 460 under the action of the negative pressure through the liquid suction pipe 452 and the liquid delivery pipe 470.

[0062] Please refer to Figure 5 , Figure 6 and Figure 7, in order to enable the lower end of the liquid extraction tube 452 to always contact the filter screen 140 and deflect synchronously with the lead-acid battery 100, the liquid extraction member 450 further includes an annular frame 4511 located below the end cover 451. The upper end of the liquid extraction tube 452 is rotatably installed on the annular frame 4511 through a rotating shaft 4512. A flexible tube 453 communicating the infusion tube 470 and the liquid extraction tube 452 is arranged in the end cover 451. An annular sealing chamber 457 is opened in the end cover 451. A sealing airbag 458 is connected to the upper end opening of the annular sealing chamber 457. A piston plate 459 is slidably embedded in the annular sealing chamber 457. A plurality of connecting columns 4510 that movably penetrate through the annular sealing chamber 457 in the circumferential direction are arranged on the piston plate 459. The extending end of the connecting column 4510 is fixedly connected to the annular frame 4511;

[0063] Specifically, when the liquid extraction plate 440 pushes the liquid extraction member 450 to insert into the corresponding liquid extraction port 150, the outer peripheral surface of the end cover 451 is adapted to the inner peripheral surface of the liquid extraction port 150, and at the same time, the sealing airbag 458 is squeezed, so that the sealing airbag 458 is compressed and contracted to realize the sealing of the liquid extraction port 150 and avoid the leakage of the electrolyte during the suction process. At the same time, due to the compression of the sealing airbag 458, the air pressure in the annular sealing chamber 457 increases, and then the piston plate 459 is pushed downward. The annular frame 4511 is pushed downward away from the end cover 451 by using the connecting column 4510 to drive the entire liquid extraction tube 452 to extend into the single cell 120, so that the lower end of the liquid extraction tube 452 contacts the filter screen 140, improving the liquid extraction depth and stability of the liquid extraction tube 452;

[0064] During the process of gradually turning over the lead-acid battery 100, the liquid extraction tube 452 can deflect synchronously around the rotating shaft 4512 towards the turning side of the lead-acid battery 100 under the action of its own gravity, so that the inlet of the liquid extraction channel 454 of the liquid extraction tube 452 is always located in the electrolyte accumulation area. At the same time, since the annular frame 4511 is always subjected to the thrust of the piston plate 459, it can be ensured that the end of the liquid extraction tube 452 away from the end cover 451 always presses against the filter screen 140, so that the lower end of the liquid extraction tube 452 is always immersed in the electrolyte, thus realizing the effective suction of the electrolyte and avoiding incomplete liquid extraction caused by the retention of part of the electrolyte.

[0065] In addition, please refer to Figure 6 and Figure 7 , in order to improve the responsiveness of the liquid extraction tube 452 to deflect with the lead-acid battery 100, a roller 455 is rotatably installed at the end of the liquid extraction tube 452 away from the end cover 451. The roller 455 is in rolling contact with the filter screen 140. A counterweight 456 is arranged on one side of the liquid extraction tube 452;

[0066] When the liquid extraction tube 452 deflects following the lead-acid battery 100, the counterweight 456 on the deflected side causes the center of gravity of the entire liquid extraction tube 452 to shift towards the side where the lead-acid battery 100 flips, enabling the liquid extraction tube 452 to deflect towards this side more quickly. Meanwhile, the roller 455 at the lower end of the liquid extraction tube 452 rolls along the filter screen 140, which can further reduce the resistance when the liquid extraction tube 452 deflects, thereby enhancing the responsiveness of the liquid extraction tube 452 to deflect following the lead-acid battery 100.

[0067] Furthermore, considering the usage cost, the electrolyte extracted from the lead-acid battery 100 can be reused after filtering out impurities. Correspondingly, please refer to Figure 8 , the liquid storage cylinder 460 includes a cylinder body 461. A suction pipe 462 communicating with the infusion pipe 470 is provided at the center of the cylinder body 461. An annular retention chamber 463 is formed between the cylinder body 461 and the suction pipe 462. The upper end opening of the suction pipe 462 communicates with the retention chamber 463. A plurality of tapered filter plates 464 are sequentially arranged from top to bottom and distributed in an interlaced manner at the upper end of the retention chamber 463; a first one-way valve 465 is installed in the suction pipe 462, and a second one-way valve 466 is installed at the bottom of the retention chamber 463;

[0068] Specifically, during the liquid extraction process, the liquid extraction pump 480 extracts the gas in the cylinder body 461. Under the negative pressure in the cylinder body 461, the first one-way valve 465 opens, and at this time, the second one-way valve 466 closes. The electrolyte in the lead-acid battery 100 is sucked into the suction pipe 462. Subsequently, when the electrolyte reaches the upper end opening of the suction pipe 462, under the action of gravity, the electrolyte flows outward into the retention chamber 463. The electrolyte passes through each layer of tapered filter plates 464 during the falling process, thereby filtering out the impurities in the electrolyte layer by layer. The electrolyte after filtration and purification is temporarily stored at the bottom of the retention chamber 463;

[0069] When the lead-acid battery 100 is repaired, the liquid extraction pump 480 blows air into the cylinder body 461, and the air pressure in the cylinder body 461 gradually increases until the second one-way valve 466 is conducted and the second one-way valve 466 opens. At this time, the first one-way valve 465 closes, so that the electrolyte in the retention chamber 463 flows back to each cell 120 through the infusion pipe 470 again to realize the re-injection of the electrolyte.

[0070] It should be noted that considering the strong acidity and corrosiveness of the electrolyte, all the structural components in contact with the electrolyte in the repair device of the present invention need to be made of materials resistant to strong acids and corrosion, such as polyolefin, polyvinylidene fluoride, and steel-lined polytetrafluoroethylene.

[0071] In another embodiment, please refer to Figure 4, the horizontal driving member 210 includes a horizontal slide rail 211 and a horizontal motor 213 fixed to the base 200. A horizontal slider 212 slidably connected to the horizontal slide rail 211 is fixedly installed at the bottom of the support table 310. The output end of the horizontal motor 213 is connected to a horizontal lead screw 214, and the horizontal slider 212 is threadedly connected to the horizontal lead screw 214;

[0072] By driving the horizontal lead screw 214 to rotate through the horizontal motor 213, the horizontal slider 212 can be driven to move horizontally along the horizontal slide rail 211, thereby driving the support table 310 and the tooling table 320 to move horizontally to adjust the horizontal position of the lead-acid battery 100.

[0073] Please refer to Figure 9 and Figure 10 , for the flipping action of the tooling table 320, straight chutes 311 are symmetrically opened on both sides of the support table 310. An arc chute 312 is connected to the middle of the straight chute 311. A connecting seat 350 is fixed to the bottom of the tooling table 320. First slide rods 330 and second slide rods 340 adapted to the straight chute 311 and the arc chute 312 are fixed to both ends of the connecting seat 350. A driving motor 370 is fixedly installed on one side of the support table 310. The output end of the driving motor 370 is connected to an eccentric rod 380. A connecting rod 360 is hinged between the eccentric rod 380 and the connecting seat 350;

[0074] Specifically, please refer to Figure 11 , when the electrolyte level in the lead-acid battery 100 gradually decreases, in order to facilitate the complete extraction of the electrolyte, the tooling table 320 needs to be flipped to one side to accumulate the electrolyte on one side. Correspondingly, by driving the eccentric rod 380 to rotate clockwise through the driving motor 370, the connecting seat 350 is pulled by the connecting rod 360, so that the first slide rod 330 and the second slide rod 340 slide along the straight chute 311 toward the side of the driving motor 370 until the second slide rod 340 reaches the end of the straight chute 311. At this time, the first slide rod 330 just reaches the connection between the straight chute 311 and the arc chute 312. As the eccentric rod 380 continues to rotate clockwise, since the second slide rod 340 cannot move further at this time, the entire connecting seat 350 is flipped upward around the second slide rod 340, and the first slide rod 330 moves along the arc chute 312, thereby driving the tooling table 320 and the lead-acid battery 100 to flip synchronously toward the side of the driving motor 370, facilitating the accumulation of the electrolyte on one side.

[0075] It should be noted that during the flipping process of the lead-acid battery 100, since the liquid extraction plate 440 is always pressed on the lead-acid battery 100, a stable assembly effect between the lead-acid battery 100 and the tooling table 320 can be ensured. Of course, in order to further prevent the lead-acid battery 100 from tipping over due to excessive flipping angle, a baffle 321 adapted to the lead-acid battery 100 is provided on the tooling table 320 near the flipping side.

[0076] It is worth noting that in this embodiment, as the eccentric rod 380 continues to rotate, after the first sliding rod 330 moves to the end of the arc-shaped chute 312 away from the straight chute 311, the first sliding rod 330 can return to the straight chute 311 along the arc-shaped chute 312 again to drive the connecting seat 350 to flip and reset, so that the lead-acid battery 100 flips to the vertical state. Subsequently, the first sliding rod 330 and the second sliding rod 340 slide synchronously along the straight chute 311 toward the side away from the driving motor 370, thereby driving the tooling table 320 and the lead-acid battery 100 to move horizontally. Then, the first sliding rod 330 and the second sliding rod 340 slide along the straight chute 311 toward the side of the driving motor 370 again, thereby driving the tooling table 320 and the lead-acid battery 100 to return horizontally. Repeating this process can achieve the reciprocating flipping and horizontal reciprocating movement of the lead-acid battery 100. In this way, when there is only a small amount of electrolyte in the lead-acid battery 100, the lead-acid battery 100 can be reciprocally flipped and oscillated, so that the remaining electrolyte in the lead-acid battery 100 quickly accumulates together under the action of oscillation, which is beneficial to the complete extraction of the electrolyte.

[0077] In a further embodiment, please refer to Figure 12 , the transverse moving member 520 includes a transverse moving slide rail 521 and a transverse moving motor 523 fixed on the support frame 510. A transverse moving slide table 522 is slidably installed on the transverse moving slide rail 521. The output end of the transverse moving motor 523 is connected with a transverse moving lead screw 524, and the transverse moving lead screw 524 is threadedly connected with the transverse moving slide table 522. By driving the transverse moving lead screw 524 to rotate by the transverse moving motor 523, the transverse moving slide table 522 can be driven to move transversely along the transverse moving slide rail 521;

[0078] The lifting member 530 includes a lifting slide rail 531 and a lifting motor 533 fixed on the transverse moving slide table 522. A lifting slide table 532 is slidably installed on the lifting slide rail 531. The output end of the lifting motor 533 is connected with a lifting lead screw 534, and the lifting lead screw 534 is threadedly connected with the lifting slide table 532. The water injection member 540 and the charging column 550 are both installed on the lifting slide table 532. By driving the lifting lead screw 534 to rotate by the lifting motor 533, the lifting slide table 532 can be driven to move up and down along the lifting slide rail 531 to realize the height adjustment of the water injection member 540 and the charging column 550;

[0079] When performing water injection repair, first, the water injection member 540 and the charging column 550 are laterally moved to one side of the lead-acid battery 100 through the lateral movement member 520. Then, the horizontal driving member 210 is used to adjust the horizontal distance between the lead-acid battery 100 and the water injection repair unit 500 until the water injection member 540 is directly above the corresponding water injection port 160, and at the same time, the charging column 550 is directly above the corresponding electrode 170. Finally, the lifting member 530 drives the water injection member 540 and the charging column 550 to move downward synchronously until the water injection member 540 is inserted into the corresponding water injection port 160, and at the same time, the charging column 550 is electrically connected to the corresponding electrode 170.

[0080] Further, please refer to Figure 13 、 Figure 14 and Figure 15 The water injection member 540 includes a water injection head 541 provided on the lifting slide 532. A tapered water guide port 542 is formed in the water injection head 541. Sector-shaped clamping blocks 543 are symmetrically arranged on both sides of the bottom of the tapered water guide port 542. A water injection pipe 560 is connected to one side of the lifting slide 532. A water injection cavity 5321 communicating the water injection pipe 560 and each tapered water guide port 542 is formed in the lifting slide 532.

[0081] Specifically, during the connection process between the water injection member 540 and the corresponding water injection port 160, the sector-shaped clamping blocks 543 are embedded in the water injection port 160 until the tapered water guide port 542 completely wraps the tapered pipe in the water injection port 160. At the same time, the sector-shaped clamping blocks 543 are radially squeezed by the side wall of the water injection port 160, so that the tapered water guide port 542 is tightly connected to the tapered pipe, effectively avoiding the leakage of distilled water. Distilled water is injected into the water injection cavity 5321 through the water injection pipe 560, and the distilled water enters the corresponding single cell 120 through each tapered water guide port 542 and the tapered pipe, thereby realizing the rapid injection of distilled water.

[0082] The specific implementation manners of this embodiment are described above, but this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
