Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, specifically to an adjustable liquid storage tank inside a gel battery. Background Technology

[0002] In existing technologies, such as the adjustable electrolyte reservoir disclosed in patent document CN208970694U, the size of the reservoir is adjusted by setting a reservoir inside the battery box and using the cooperation between a movable baffle and an outlet hole. However, in practical applications, this technology has the following problems: First, the adjustment operation is complex. Existing technologies require sliding the movable baffle back and forth inside the reservoir, and the position of the movable baffle needs to be limited by the insertion of a positioning block on the box cover into a positioning groove on the top of the bracket. This operation method is not only cumbersome, but also prone to problems such as inaccurate positioning and uneven baffle sliding, causing great inconvenience to users and reducing work efficiency. Second, the contact effect between the electrolyte and the electrode plates is poor. Although the adjustment method of the reservoir in existing technologies can change its size, the contact area and contact effect between the electrolyte and the electrode plate assembly are not optimized during the adjustment process. Inaccurate electrolyte level control leads to insufficient contact between the electrolyte and the plates, affecting the battery's charging and discharging efficiency and overall performance. Under different operating conditions, this insufficient contact can further reduce the battery's lifespan and stability. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: an adjustable liquid storage chamber inside a gel battery, including an outer shell 1 and a top shell 2, with the top shell 2 fixedly installed above the outer shell 1. Multiple first baffles 8 and multiple second baffles 9 are fixedly installed inside the outer shell 1, each first baffle 8 and each second baffle 9 dividing the interior of the outer shell 1 into multiple liquid storage chambers 6 and multiple electrolysis chambers 7. A manifold 21 is provided on the lower wall of each second baffle 9, and the liquid storage chamber 6 communicates with an adjacent electrolysis chamber 7 through the manifold 21.

[0028] Each electrolysis chamber 7 of the outer casing 1 is fixedly installed with an electrode assembly. Multiple regulating components are installed on the top casing 2, with the lower middle portion of each regulating component located within its respective storage chamber 6. The regulating components push the electrolyte within the storage chamber 6, causing the electrolyte to flow into the electrolysis chamber 7 through the manifold 21. This raises the electrolyte level within the electrolysis chamber 7, ensuring sufficient and large-area contact between the electrolyte and the electrode assembly.

[0029] The outer casing 1 has several electrolyte storage chambers 6 and 7, which hold both electrolyte and electrode assembly. After prolonged use, the electrode assembly causes varying degrees of electrolyte loss. As the electrolyte level decreases, the contact area between the electrolyte and the electrode assembly reduces, leading to a decrease in overall battery performance. By adjusting the pressure of the assembly on the electrolyte in the storage chambers 6, the electrolyte level in the storage chambers 6 decreases. The electrolyte then flows through the manifold 21 into the electrode chambers 7, causing the electrolyte level in the electrode chambers 7 to rise. This allows the electrolyte to cover a larger area of ​​the electrode assembly, improving battery performance.

[0030] Specifically, the adjusting assembly includes a bolt 16 and an adjusting plate 17. The upper part of the bolt 16 penetrates the top shell 2 and the two are rotatably connected. The rotatable connection between the bolt 16 and the top shell 2 is sealed, for example, by using a sealing ring. The middle and lower part of the bolt 16 penetrates the adjusting plate 17 and the two are threadedly connected. The threaded connection between the bolt 16 and the adjusting plate 17 is sealed, for example, by using a sealing ring. The adjusting plate 17 is slidably installed in the liquid storage cavity 6 of the outer shell 1, and a sealing strip 18 is embedded in the outer walls of the adjusting plate 17.

[0031] The sealing strip 18 and each sealing ring are used to enhance the sealing effect and prevent electrolyte leakage. The bolt 16 is made of non-metallic material. When the bolt 16 is rotated with a screwdriver, the bolt 16 pushes the adjusting plate 17 connected to it to rise or fall. When the adjusting plate 17 falls, it pushes the electrolyte in the storage chamber 6, so that the electrolyte flows into the electrolysis chamber 7 through the manifold 21.

[0032] More specifically, a recessed groove 15 is provided on the top shell 2, and a through hole 19 is provided in the recessed groove 15 of the top shell 2. The recessed groove 15 and the through hole 19 are connected, and the upper part of the bolt 16 passes through the through hole 19 on the top shell 2. A cover plate 5 is embedded and fixedly installed in the recessed groove 15 of the top shell 2.

[0033] The cover plate 5 is used to cover the recessed groove 15, and then cover each bolt 16, thereby sealing each bolt 16 to prevent electrolyte leakage and to prevent the bolt 16 from being accidentally rotated due to exposure.

[0034] Specifically, a circuit cavity 20 is formed inside the top shell 2, and a negative terminal 3 and a positive terminal 4 are fixedly installed on the top wall of the top shell 2. The electrode assembly includes a positive busbar 10, a negative busbar 11, multiple positive electrode plates 14, multiple separators 13, and multiple negative electrode plates 12. Each positive electrode plate 14, each separator 13, and each negative electrode plate 12 is fixedly installed in the electrolysis cavity 7 of the outer shell 1. Each positive electrode plate 14 and each negative electrode plate 12 are arranged alternately in sequence. The separator 13 is located between adjacent positive electrode plates 14 and negative electrode plates 12, and the separator 13 separates adjacent positive electrode plates 14 and negative electrode plates 12. The negative busbar 11 is fixedly connected to each negative electrode plate 12 and electrically connected to each negative electrode plate 12. The negative busbar 11 is also electrically connected to the negative terminal 3. The positive bus 10 is fixedly connected to each positive plate 14, and the positive bus 10 is electrically connected to each positive plate 14. The positive bus 10 is also electrically connected to the positive terminal 4.

[0035] The separator 13 separates the positive plate 14 and the negative plate 12 to prevent short circuits caused by contact between them. During the charging and discharging process, current is transmitted through the negative terminal 3 and the positive terminal 4 to the negative busbar 11 and the positive busbar 10, respectively, and then distributed to the negative plate 12 and the positive plate 14 through the negative busbar 11 and the positive busbar 10, thereby realizing the conversion between electrical energy and chemical energy. Due to the structural design of the plate assembly and the optimized regulation of the electrolyte level by the regulating component, the entire battery maintains good performance and stability during charging and discharging, improving its service life and reliability.

[0036] In use, the size of the storage tank is first adjusted according to actual needs. By rotating bolt 16, the adjusting plate 17 is driven to move up and down within the storage chamber 6. When the adjusting plate 17 moves downward, it pushes the electrolyte in the storage chamber 6, causing it to flow into the electrolysis chamber 7 through the manifold 21, thereby raising the electrolyte level in the electrolysis chamber 7. When the adjusting plate 17 moves upward, the electrolyte level drops accordingly. In this way, the size of the storage tank can be quickly adjusted to meet different usage scenarios and operating conditions.

[0037] After the electrolyte reservoir is adjusted to the appropriate size, the electrolyte is injected into the electrolyte storage chamber 6. Because sealing strips 18 are installed on the outer walls of the adjusting plate 17, the electrolyte will not leak from the gap between the adjusting plate 17 and the inner wall of the electrolyte storage chamber 6 during adjustment and use, ensuring the sealing performance of the entire electrolyte reservoir system. The electrolyte flows into the electrolyte chamber 7 through the manifold 21, making full contact with the electrode assembly. Since the positive electrode 14 and negative electrode 12 in the electrode assembly are arranged alternately and separated by the partition 13, this structure allows the electrolyte to have full and large-area contact with the electrode assembly, thereby improving the chemical reaction efficiency between the electrolyte and the electrode, and thus improving the charging and discharging efficiency and performance of the battery.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
