Description

[0001] This invention belongs to the field of lead-acid battery manufacturing technology, and particularly relates to a lead-acid battery charging rack. Background Technology

[0002] Storage batteries are categorized into large-capacity, medium-capacity, and small-capacity batteries. A storage battery is a device that directly converts chemical energy into electrical energy. It is designed for rechargeability, achieving recharging through a reversible chemical reaction. The most common type is the lead-acid battery, a type of secondary battery. Its working principle is as follows: during charging, external electrical energy regenerates the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output, such as in commonly used mobile phone batteries.

[0003] The prior art discloses some invention patents in the field of lead-acid battery manufacturing technology. Among them, the invention patent with publication number CN103023094A discloses a water-cooled battery charging rack with a water tank, which can effectively solve the problem that the existing charging rack is too long when a small batch of batteries needs to be charged, resulting in resource waste. A water-cooled battery charging rack includes a water tank body comprising an outer layer and an inner layer of the same shape tightly bonded together. The inner layer has at least one dividing groove separating it, and also includes a partition plate separating the inner layer. The partition plate is disposed within the dividing groove, and a fixing device is provided within the dividing groove to position the partition plate. By slightly modifying the existing water tank body, adding the dividing groove, inserting the partition plate into the dividing groove, and fixing the partition plate with the fixing device, the water tank can maximize resource utilization when dealing with different numbers of batteries, avoiding waste. However, this technical solution still has some shortcomings in its application. Existing technologies often use flowing water for heat dissipation and circulate water through the water tank. When only a small number of batteries need to be charged, the excessive length of the charging rack inevitably requires a large amount of water, resulting in significant resource waste.

[0004] Based on this, the present invention designs a lead-acid battery charging rack to solve the above problems. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a technical solution: a lead-acid battery charging rack, including a base 1. Vertical water-cooling pipes A2 and B3 are respectively connected to the two sides of the top of the base 1. Multiple water-cooling components 4 are sleeved on both the vertical water-cooling pipes B3 and A2. A horizontal water-cooling pipe 5 is connected between two water-cooling components 4 at the same height. Multiple battery support components 6 are connected to the horizontal water-cooling pipe 5. Lifting ports are opened inside the horizontal water-cooling pipe 5 corresponding to the multiple battery support components 6. A partition plate B is inserted into the lifting port. A support spring C is connected to the partition plate B. The partition plate B is elastically supported and connected to the horizontal water-cooling pipe 5 through the support spring C. An L-shaped plate is connected to the bottom of the partition plate B. Bridging and guiding components A9 and B10 are respectively connected to the bottom of the horizontal water-cooling pipe 5 corresponding to the two sides of the partition plate B. The other ends of the bridging and guiding components B10 and A9 are connected to the bottom of the corresponding battery support components 6.

[0019] Specifically, a water inlet pipe A7 is connected to the vertical water-cooling pipe A2 corresponding to the water bridging component 4, and the other end of the water inlet pipe A is connected to one end of the horizontal water-cooling pipe 5. A water inlet pipe B is connected to the vertical water-cooling pipe B3 corresponding to the water bridging component 4, and the other end of the water inlet pipe B is connected to the other end of the horizontal water-cooling pipe 5. The water bridging component 4 includes a funnel-shaped cover 401 that is snapped into the vertical water-cooling pipe A2 or the vertical water-cooling pipe B3. A ball valve 402 is sleeved inside the bottom port of the funnel-shaped cover 401. A lifting shaft 403 is connected to the bottom of the ball valve 402. A sealing plate A406 is sleeved on the lifting shaft 403. The sealing plate A406 is snapped into the vertical water-cooling pipe A2 or the vertical water-cooling pipe B3. A support spring A404 is sleeved on the lifting shaft 403. The ball valve 402 is elastically supported and connected to the sealing plate A406 through the support spring A404.

[0020] Specifically, in this embodiment, the lead-acid batteries to be charged are placed from low to high. When multiple battery carriers 6031 on the same layer hold lead-acid batteries to be charged, the overall weight of the layer increases. The gravity generated by the lead-acid batteries to be charged acts on the horizontal water-cooling pipes 5 of the layer through the battery carrier assembly 6. The horizontal water-cooling pipes 5 drive the external bridging sleeves 408 connected at both ends to slide downward on the vertical water-cooling pipes A2 and B3 respectively. During the downward movement of the external bridging sleeves 408, the bridging rods are driven. As 405 slides down into the lifting port, the bridging rod 405 will exert a downward pulling force on the bridging rod 405. Under the action of the downward pulling force, the bridging rod 405 drives the ball valve 402 to slide downward on the inside of the sealing plate A406, and squeezes the support spring A404 to cause it to undergo elastic deformation. When the water inlet hole A409 is fully connected with the water inlet hole B, the bridging rod 405 descends to the lowest point of the lifting port. At this time, the ball valve 402 is completely disengaged from the bucket-shaped cover 401, and the upper and lower sides of the bucket-shaped cover 401 are in a conductive state.

[0021] A bridging rod 405 is connected to the bottom end of the lifting shaft 403. Lifting ports are opened on the outer walls of the vertical water-cooling pipes A2 and B3 corresponding to the bridging rod 405. External bridging sleeves 408 are fitted onto the corresponding lifting ports on the vertical water-cooling pipes A2 and B3. The external bridging sleeves 408 are connected to the lifting shaft 403 via the bridging rod 405. Sealing plates B407 are snapped onto the top of the corresponding funnel-shaped covers 401 inside the vertical water-cooling pipes A2 and B3. The drainage pipes A and B8... All ports are located between the sealing plate B407 and the bucket-shaped cover 401. The battery support assembly 6 is connected to the horizontal frame 601 with the horizontal water cooling pipe 5. The horizontal frame 601 has a track groove. Two strip slide rails 602 are slidably connected in the track groove. The same battery elastic support member 603 is connected between the two strip slide rails 602. The sealing plate C604 is snapped into the port at the bottom of the battery elastic support member 603. The partition plate A605 is connected to the sealing plate C604.

[0022] Specifically, this embodiment involves controlling the operation of the water pump 1103, which drives the water flow to the diversion pipe 1101. After being diverted by the diversion pipe 1101, the cooling water for the lead-acid battery to be charged flows sequentially through the water inlet A409 and the water inlet B into the vertical water-cooling pipe A2. The cooling water for the lead-acid battery to be charged that enters the vertical water-cooling pipe A2 passes through the funnel-shaped cover 401 and flows into the diversion pipe A. Under the guidance of the diversion pipe A, the water for the lead-acid battery to be charged enters the horizontal water-cooling pipe 5 set in this layer.

[0023] Specifically, the battery elastic support component 603 includes a battery support base 6031 connected to two strip slide rails 602. The battery support base 6031 has a groove 6032 corresponding to the strip slide rails 602. A slider 6034 is slidably connected in the groove 6032. A support spring B6033 is connected to the slider 6034. The slider 6034 is elastically supported and connected to the top of the groove 6032 through the support spring B6033.

[0024] The sealing plate C604 is snapped into the port at the bottom of the battery carrier 6031. The sealing plate C604 is elastically connected to the inner top of the battery carrier 6031 via a partition plate A605, dividing the internal space of the battery carrier 6031 into two parts. The ports of the bridging current-draining assembly A9 and the bridging current-draining assembly B10 are located on both sides of the partition plate A605. The bridging current-draining assembly A9 and the bridging current-draining assembly B10 have the same structure. The bridging current-draining assembly includes a bridge... Connector A901, the end of the bridge connector A901 is connected to the bottom of the horizontal water cooling pipe 5, the other end of the bridge connector is equipped with a pipe valve 902, the other end of the pipe valve 902 is equipped with a bridge connector B904, the other end of the bridge connector B904 is connected to the bottom of the sealing plate C604, the pipe valve 902 is equipped with a handle 903, and a transition spring 905 is sleeved on the shaft connected to the handle 903, the handle 903 is elastically connected to the pipe valve 902 through the transition spring 905.

[0025] Specifically, in this embodiment: when one or more of the multiple battery carriers 6031 located on this layer are filled with lead-acid batteries to be charged, the battery carrier 6031 filled with the lead-acid batteries to be charged slides on the slider 6034 through the slide groove 6032 under the action of gravity, and squeezes the support spring B6033 to cause elastic deformation. During the downward movement of the battery carrier 6031, the sealing plate C604 pushes the handle 903, the handle 903 drives the shaft connected to it to rotate, and twists the adapter spring 905 to cause elastic deformation, the pipeline valve 902 is opened, and the sealing plate C604 also pushes the L-shaped plate during the downward movement. The L-shaped plate drives the partition plate B to slide downward. The partition plate B has a through hole corresponding to the interior of the horizontal water cooling pipe 5. When the L-shaped plate drives the partition plate B to the maximum extent, the through hole on the partition plate B is located below the horizontal water cooling pipe 5.

[0026] Specifically, the outer bridge sleeve 408 is provided with a water inlet hole A409, and the vertical water cooling pipe A2 and water cooling pipe B are provided with a water inlet hole B below the water inlet hole A409. A water circulation component 11 is externally connected between the vertical water cooling pipe A2 and the vertical water cooling pipe B3. The water circulation component 11 includes a branch pipe 1101 and a manifold pipe 1102. Multiple branches of the branch pipe 1101 are respectively connected to multiple water inlets A409 located on one side of the vertical water cooling pipe A2. Multiple branches of the manifold pipe 1102 are respectively connected to multiple water inlets A409 located on one side of the vertical water cooling pipe B3. A water pump 1103 is installed at the bottom of the base 1. The end of the branch pipe 1101 is installed at the outlet of the water pump 1103, and the end of the manifold pipe 1102 is installed at the return port of the water pump 1103.

[0027] Specifically, this embodiment involves controlling the operation of water pump 1103, which drives water to flow towards the diversion pipe 1101. After being diverted by the diversion pipe 1101, the cooling water for the lead-acid battery to be charged flows sequentially through the water inlet A409 and water inlet B into the vertical water-cooling pipe A2. The cooling water for the lead-acid battery to be charged that enters the vertical water-cooling pipe A2 passes through the funnel-shaped cover 401 and flows into the diversion pipe A. Under the guidance of the diversion pipe A, the cooling water for the lead-acid battery to be charged enters the horizontal water-cooling pipe 5 set in this layer. The cooling water for the lead-acid battery to be charged that enters the battery carrier 6031 flows from one side of the partition plate A605 to the other side, and finally flows back to the horizontal water-cooling pipe 5 through the bridging diversion component B10. The cooling water for the lead-acid battery to be charged that is located in the horizontal water-cooling pipe 5 finally flows into the vertical water-cooling pipe B3 through the diversion pipe B8, and finally flows back through the manifold 1102.

[0028] Working principle and usage: The lead-acid batteries to be charged are placed from low to high. When multiple battery carriers 6031 on the same layer have lead-acid batteries to be charged, the overall weight of the layer increases. The gravity generated by the lead-acid batteries to be charged acts on the horizontal water-cooling pipes 5 on the layer through the battery carrier assembly 6. The horizontal water-cooling pipes 5 drive the external bridging sleeves 408 connected at both ends to slide downward on the vertical water-cooling pipes A2 and B3 respectively. During the downward movement of the external bridging sleeves 408, the bridging rods 405 are driven to... As the lifting port slides down, the bridging rod 405 will exert a downward pulling force on it. Under the action of the downward pulling force, the bridging rod 405 will drive the ball valve 402 to slide downward on the inside of the sealing plate A406, and squeeze the support spring A404 to cause it to undergo elastic deformation. When the water inlet hole A409 is fully connected with the water inlet hole B, the bridging rod 405 will descend to the lowest point of the lifting port. At this time, the ball valve 402 will be completely disengaged from the bucket-shaped cover 401, and the upper and lower sides of the bucket-shaped cover 401 will be in a conductive state. The water pump 1103 is controlled to run, and the water pump 1103 drives the water to flow to the diversion pipe 1101. After being diverted by the diversion pipe 1101, the cooling water for the lead-acid battery to be charged flows through the water inlet A409 and the water inlet B in sequence into the vertical water cooling pipe A2. The cooling water for the lead-acid battery to be charged that enters the vertical water cooling pipe A2 passes through the funnel-shaped cover 401 and flows into the diversion pipe A. Under the guidance of the diversion pipe A, the water for the lead-acid battery to be charged enters the horizontal water cooling pipe 5 set in this layer. When one or more lead-acid batteries to be charged are placed on the multiple battery carriers 6031 located on this layer, the battery carrier 6031 with the lead-acid batteries to be charged slides on the slider 6034 through the slide groove 6032 under the action of gravity, and compresses the support spring B6033 to cause elastic deformation. During the downward movement of the battery carrier 6031, the sealing plate C604 will push the handle 903, the handle 903 will drive the shaft connected to it to rotate, and twist the adapter spring 905 to cause elastic deformation, the pipeline valve 902 will be opened. During the downward movement, the sealing plate C604 will also push the L-shaped plate, the L-shaped plate will drive the partition plate B to slide downward. The partition plate B has a through hole corresponding to the horizontal water cooling pipe 5. The L-shaped plate drives the partition plate B to slide downward. When the partition B descends to its maximum extent, the through hole on the partition B is located below the horizontal water-cooling pipe 5. The cooling water for the lead-acid batteries waiting to be charged, which enters the battery carrier 6031, flows from one side of the partition A605 to the other side, and finally flows back into the horizontal water-cooling pipe 5 through the bridging and guiding assembly B10. The cooling water for the lead-acid batteries waiting to be charged in the horizontal water-cooling pipe 5 finally flows into the vertical water-cooling pipe B3 through the guiding pipe B8, and finally flows back through the manifold 1102. This maximizes the utilization of water resources when dealing with different numbers of lead-acid batteries waiting to be charged, avoids waste, and also reduces the load on the water pump 1103, thus achieving energy saving and emission reduction to a certain extent. The structure is simple and easy to use, and it is suitable for the production of healthy and environmentally friendly lead-acid batteries.
