Description

Technical Field

[0001] This utility model relates to the field of electrode technology, and in particular to an assembly structure for a tubular bipolar electrode. Background Technology

[0002] Electrode plates are the core electrode components of chemical power sources, consisting of a sheet-like porous structure made up of active materials and a current collector supporting conductivity. As a fundamental component of electrochemical devices such as lead-acid batteries, alkaline batteries, and fuel cells, they achieve the storage and release of electrical energy through the reversible chemical reactions of the active materials.

[0003] In existing technologies, lead-acid batteries require the use of electrode plates. Currently, most electrode plates have alternating positive and negative electrodes, with an active material carrier filling between them. The positive and negative electrodes are set separately, and metal frames are welded to both ends of the negative and positive electrodes for overall connection. However, when this method of connection is needed, the positive and negative electrodes must be completely removed and the active carrier position must be refilled, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing lead-acid batteries require the use of electrode plates, and currently, most electrode plates have alternating positive and negative electrodes with an active material carrier filled between them. The positive and negative electrodes are set separately, and metal frames are welded to the ends of both the negative and positive electrodes for overall connection. However, when this method of connection is needed, the positive and negative electrodes must be completely removed and the active carrier position must be refilled, which is inconvenient. Therefore, this invention proposes an assembly structure for a tubular bipolar electrode plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an assembly structure for a tubular bipolar plate, comprising an insulating support, a positive electrode, and a negative electrode. A slot is formed through both sides of the center of the insulating support, and the positive and negative electrodes are inserted into the slot. An assembly plate is fixedly connected to one side of the upper end of both the positive and negative electrodes. Side limiting grooves are formed above the center of both sides of the assembly plate. An assembly block is provided above both the positive and negative electrodes. A slot is formed at the lower end of the assembly block, and a slot is formed through one side of the assembly block. The slot is located on both sides of the slot and is connected to it. The slot is inserted into the assembly plate. A support rod is inserted between the side limiting groove and the slot, and the length of the support rod is greater than the length of the slot.

[0006] Preferably, the assembly block has inner sealing grooves on both sides, and the inner sealing grooves are connected to slot number three.

[0007] Preferably, an electrical contact metal plate is fixedly connected to the upper end of the assembly block, and a connector is fixedly connected to one side of the electrical contact metal plate.

[0008] Preferably, a side sealing plate is fixedly connected to one side of the support rod, and the side sealing plate is engaged with the inner sealing groove.

[0009] Preferably, a guide groove is provided at the upper end of the support rod on the side away from the side sealing plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the No. 2 slot, in conjunction with the assembly plate, allows the positive and negative electrode plates to be connected to the assembly block via a plug-in method. Reinforcement with a support rod ensures connection stability. Disassembly is simple: just remove the support rod to pull out the positive and negative electrode plates. This method allows each positive and negative electrode plate to be disassembled individually, making disassembly convenient and quick. Furthermore, the guide groove guides the side limiting groove when there is a misalignment between the No. 3 slot and the side limiting groove, thus restricting the assembly plate's position after installation and facilitating installation.

[0019] Example: Figures 1-4 As shown, this utility model provides an assembly structure for a tubular bipolar electrode plate, including an insulating support 1, a positive electrode plate 2, and a negative electrode plate 6. A slot 9 is formed through both sides of the center of the insulating support 1. Both the positive electrode plate 2 and the negative electrode plate 6 are inserted into the slot 9. An assembly plate 12 is fixedly connected to one side of the upper end of both the positive electrode plate 2 and the negative electrode plate 6. Side limiting grooves 10 are formed above the center of both sides of the assembly plate 12. An assembly block 3 is provided above both the positive electrode plate 2 and the negative electrode plate 6. A slot 13 is formed at the lower end of the assembly block 3. A slot 14 is formed through one side of the assembly block 3. The slot 14 is located on both sides of the slot 13 and is connected to it. The assembly block 3 is inserted into the assembly plate 12. A support rod 8 is inserted between the side limiting groove 10 and the third slot 14. The length of the support rod 8 is greater than the length of the third slot 14. Both sides of the assembly block 3 are provided with inner sealing grooves 15, which are connected to the third slot 14. The upper end of the assembly block 3 is fixedly connected to the power-connecting metal plate 4. A connector 5 is fixedly connected to one side of the power-connecting metal plate 4. A side sealing plate 7 is fixedly connected to one side of the support rod 8. The side sealing plate 7 is snapped into the inner sealing groove 15. A guide groove 11 is provided at the upper end of the support rod 8 on the side away from the side sealing plate 7. The second slot 13 can be made of the same material as the power-connecting metal plate 4 or a non-metallic material, depending on the requirements.

[0020] The specific settings and functions of this embodiment are described in detail below. With the setting of slot 13, in conjunction with the assembly plate 12, the connection between the positive electrode 2 and the negative electrode 6 and the assembly block 3 is installed by plugging in. The connection is reinforced by the support rod 8, which ensures the stability of the connection. At the same time, during disassembly, the positive electrode 2 and the negative electrode 6 can be pulled out simply by removing the support rod 8. In this way, each positive electrode 2 and the negative electrode 6 can be disassembled individually, which is convenient and quick. With the setting of the guide groove 11, when there is a positional deviation between slot 14 and the side limiting groove 10, the guide groove 11 can guide the side limiting groove 10 and limit the position of the assembly plate 12 after installation, making the installation more convenient.

[0021] The usage and working principle of this device are as follows: During installation, first insert the positive electrode 2 and the negative electrode 6 into slot 1 9, then insert the assembly plate 12 into slot 2 13, and then insert the support rod 8 into slot 3 14. Use a hammer to tap the side sealing plate 7 until the side sealing plate 7 is engaged with the inner sealing groove 15. This completes the installation. Then fill the space between the insulating carrier 1 with an active material carrier. During disassembly, tap the end of the support rod 8 away from the side sealing plate 7 to disconnect the side sealing plate 7 from the inner sealing groove 15, and then pull out the side sealing plate 7.
