Description

Technical Field

[0001] This utility model relates to the field of metal protection technology, specifically to a selective composite sacrificial anode. Background Technology

[0002] Sacrificial anode is an electrochemical corrosion protection technique that achieves corrosion protection by attaching a more reactive metal, the sacrificial anode, to the metal being protected. Because the sacrificial anode has a lower electrode potential, it preferentially undergoes oxidation (corrosion) in an electrolyte environment, releasing electrons that flow to the protected metal, causing it to form a cathode and thus preventing corrosion.

[0003] Currently, the anodes used in sacrificial anode protection technology are mostly single metals or simple alloys. While these anodes can provide some corrosion protection under specific conditions, their limitations become apparent when faced with complex and diverse application scenarios. For example, in environments with large temperature fluctuations, complex media composition, or intermittent wet-dry cycles, anodes made of a single material often struggle to release electrons stably, failing to provide continuous and effective cathodic protection for the protected metal. This results in a significant reduction in corrosion protection and may even accelerate equipment corrosion due to insufficient protection, making it difficult to meet the long-term protection requirements in diverse scenarios. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a selective composite sacrificial anode that can be configured with multiple different anodes and is suitable for situations where the position of the cathode varies.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a selective composite sacrificial anode, comprising:

[0006] The frame includes an upper frame, a lower frame, and support rods. The support rods are fixedly disposed between the upper frame and the lower frame, and there are several of them. An upper positioning ring and a lower positioning ring are fixedly disposed on the inner side of the upper frame and the lower frame, respectively.

[0007] Anode plates are located inside the frame and are provided at equal intervals along the upper and lower positioning rings. The anode plates are made of different materials.

[0008] The connector includes a connecting plate and a connecting rod. The connecting plate is located above the upper frame and is connected to each anode plate. The connecting rod is fixedly located above the connecting plate.

[0009] Furthermore, the upper positioning ring and the lower positioning ring are respectively connected and fixed to the upper frame and the lower frame by a number of connecting strips, and the connecting strips are equidistantly distributed around the upper positioning ring and the lower positioning ring.

[0010] Furthermore, the lower positioning ring is provided with a positioning groove that matches the anode plate, and the upper positioning ring is provided with a positioning hole through which the anode plate slides.

[0011] Furthermore, a label plate corresponding to the anode plate is fixedly provided on the inner side of the upper positioning ring.

[0012] Furthermore, L-shaped positioning plates with matching connecting plates are fixedly provided at the four corners of the upper frame, and the connecting plates are located inside the L-shaped positioning plates.

[0013] Furthermore, the anode plate is welded to the lower positioning ring, the upper positioning ring, and the connecting plate.

[0014] Compared with existing technologies, this invention has the following advantages: It utilizes multiple anodes of different materials, demonstrating significant advantages when the cathode position changes frequently. Multiple anodes can adapt to different environmental conditions; whether the cathode is in high humidity, high salinity, or other complex conditions, the synergistic effect of different anode materials ensures stable cathodic protection. Simultaneously, the label plate inside the upper positioning ring allows for quick identification of different anodes, facilitating accurate replacement of the corresponding anode based on cathode position changes, thus improving maintenance efficiency. Furthermore, the welded connections of all components and the robust frame structure maintain overall stability even with frequent cathode position changes, preventing loosening that could affect the protective effect and significantly expanding its applicability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4A selective composite sacrificial anode includes: a frame comprising an upper frame 1, a lower frame 2, and support rods 3. The support rods 3 are fixedly disposed between the upper frame 1 and the lower frame 2, and are provided in plurality of such rods. An upper positioning ring 4 and a lower positioning ring 5 are respectively fixedly disposed on the inner sides of the upper frame 1 and the lower frame 2. The upper positioning ring 4 and the lower positioning ring 5 are respectively connected and fixed to the upper frame 1 and the lower frame 2 by a plurality of connecting strips 9. The connecting strips 9 are equidistantly distributed around the upper positioning ring 4 and the lower positioning ring 5, which can enhance the connection stability between the positioning ring and the frame and prevent the positioning ring from deforming under stress.

[0022] Combined with appendix Figure 1 The anode plate 6 is located inside the frame and is provided with several equidistant positions along the upper positioning ring 4 and the lower positioning ring 5. The lower positioning ring 5 is provided with a positioning groove that matches the anode plate 6, and the upper positioning ring 4 is provided with a positioning hole through which the anode plate 6 slides, which can precisely limit the position of the anode plate 6 and ensure installation accuracy.

[0023] Combined with appendix Figure 1 The anode plates 6 are made of different materials. The inner side of the upper positioning ring 4 is fixed with a label plate 10 that corresponds one-to-one with the anode plate 6, which can quickly distinguish the anode plates of different materials and facilitate identification during later maintenance and replacement.

[0024] Combined with appendix Figure 1 Appendix Figure 2 The connector includes a connecting plate 7 and a connecting rod 8. The connecting plate 7 is located above the upper frame 1 and connects to each anode plate 6. The connecting rod 8 is fixedly located above the connecting plate 7. L-shaped positioning plates 11, matching the connecting plate 7, are fixedly installed at the four corners of the upper frame 1. The connecting plate 7 is located inside the L-shaped positioning plates 11, which position the connecting plate 7 to ensure accurate connection between the connecting plate and each anode plate 6, thus improving the assembly efficiency of the overall structure. The anode plates 6 are welded to the lower positioning ring 5, the upper positioning ring 4, and the connecting plate 7, which enhances the connection strength between components, prevents loosening during use, and extends the service life of the anodes.

[0025] The specific implementation of this utility model is as follows: In use, first fix the frame in place. Based on the environment of the cathode, refer to the label plate 10 inside the upper positioning ring 4 and install the corresponding anode plate 6. Align the lower end of the anode plate 6 with the positioning groove of the lower positioning ring 5 and insert it, with the upper end passing through the positioning hole of the upper positioning ring 4, so that the anode plate 6 is accurately installed inside the frame. Next, place the connecting plate 7 inside the L-shaped positioning plate 11 above the upper frame 1, connecting it to the top of each anode plate 6, and then weld and fix each connection point. Finally, connect the entire device to the cathode to be protected via the connecting rod 8 to achieve the protective function. During later maintenance, different anode plates 6 can be quickly identified according to the label plate 10 and replaced as needed, ensuring continuous and stable operation even when the cathode position changes.
