Description
Technical Field
[0001] This utility model relates to the field of circulating cooling water cathodic protection, specifically a silver halide reference electrode for a circulating cooling water cathodic protection system. Background Technology
[0002] A circulating cooling water cathodic protection system is a technical means to prevent corrosion of metal equipment and pipelines in a circulating cooling water system. The system applies sufficient cathodic current to the protected metal structure, causing a negative shift in the metal surface potential, thereby inhibiting the anodic dissolution reaction of the metal and reducing the corrosion potential to a range where corrosion does not occur, thus protecting the metal. The protection system typically uses a reference electrode, which serves as a reference electrode when measuring various electrode potentials. A cell is formed by the electrode to be measured and the reference electrode with a precisely known electrode potential value. By measuring the electromotive force of the cell, the electrode potential of the measured electrode can be calculated.
[0003] Currently, silver halide reference electrodes are typically rod-shaped. The connecting core rod inside the reference electrode is easily worn down and damaged, making it inconvenient to disassemble and replace the connecting core rod, which can damage the reference electrode. Furthermore, the reference electrode is usually filled with a chemical solution, and the poor sealing effect of the reference electrode can easily cause the chemical solution to spill. Therefore, it is necessary to design a silver halide reference electrode for a circulating cooling water cathodic protection system to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please refer to Figure 1-6 As shown, this utility model provides a silver halide reference electrode for a circulating cooling water cathodic protection system, including a reference electrode body 1, a connecting core rod 2 embedded inside the body 1, protective blocks 3 fixedly connected to both ends of the connecting core rod 2, a chemical solution filling the body 1, a fixing cap 4 screwed onto the top of the body 1, a connecting rod 5 installed inside and extending out of the fixing cap 4, a protective sleeve 6 for protecting the body 1 sleeved onto the bottom of the body 1, a protective pad 14 fixedly installed inside the protective sleeve 6, a replacement fixing component installed on the outside of the fixing cap 4, a sealing component installed inside the fixing cap 4, and the protective sleeve 6 being made of rubber.
[0025] Furthermore, the protective block 3 can limit and fix the connecting core rod 2 to prevent damage to the connecting core rod 2. The protective sleeve 6 is fixedly fitted to the bottom of the body 1. The protective pad 14 inside the protective sleeve 6 can protect the bottom of the connecting core rod 2 to prevent the connecting core rod 2 from being damaged by bumps. The top of the body 1 is fixed to the connecting core rod 2 by the fixing cap 4. The fixing cap 4 is screwed to the body 1 and can limit and fix the extended connecting rod 5. The fixing component can be used to fix the connecting rod 5 again. At the same time, the sealing component inside the fixing cap 4 can seal the chemical solution inside the body 1 to prevent the chemical solution from spilling.
[0026] Specifically, the fastener includes a fixing ring 7 screwed onto the outside of the fixing cap 4, a washer 8 laid on the inside of the fixing ring 7, a fixing part 9 extending from the outside of the connecting rod 5, a fixing groove 10 for fixing the connecting rod 5 opened on the inside of the fixing ring 7, and a plurality of anti-slip parts 17 arranged in a circle fixedly connected to the outside of the fixing ring 7 near the end.
[0027] The connecting rod 5 can be fixed by screwing the fixing cap 4 to the body 1. Then, the fixing ring 7 is fitted onto the outside of the connecting rod 5 to press down the connecting rod 5. The washer 8 on the inside of the fixing groove 10 fits into the fixing part 9 on the outside of the connecting rod 5, which improves the convenience and stability of installing and replacing the connecting rod 5 and the connecting core rod 2.
[0028] More specifically, the sealing element includes three elastic rings 11 that are evenly arranged inside the fixed cap 4, with a gasket 12 fixedly connected to the bottom of the three elastic rings 11, a spring piece 15 fixedly connected to the inside of the elastic rings 11, a sealing ring 13 fixedly connected to the bottom of the gasket 12, and a sealing ring 16 fixedly connected to the inside of the protective block 3.
[0029] Among them, the spring sheet 15 can support the elastic ring 11, thereby causing the elastic ring 11 to expand and deform to press down the gasket 12. Then the gasket 12 squeezes the sealing ring 13 to seal the gap between the protective block 3 and the body 1. The sealing ring 16 on the inner side of the protective block 3 can seal the gap between the chemical fixing block and the body 1, preventing the chemical solution from overflowing and improving the sealing effect of the body 1.
[0030] Working principle: First, the fixing cap 4 is screwed onto the outside of the body 1 and rotated. At this time, the spring piece 15 supports the elastic ring 11, causing the elastic ring 11 to expand and deform, pressing down on the washer ring 12. Then, the washer ring 12 squeezes the sealing ring 13 to seal the gap between the protective block 3 and the body 1. At the same time, the sealing ring 16 on the inner side of the protective block 3 seals the gap between the fixing block and the body 1, preventing the chemical solution inside the body 1 from overflowing. When it is necessary to replace the connecting core rod 2, the fixing ring 7 and the fixing cap 4 are screwed off respectively. The fixing ring 7 is detached from the connecting rod 5, and then the fixing cap 4 is screwed on and rotated to disassemble and replace the connecting rod 5 and the connecting core rod 2.
