Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anode reference devices, in particular to a sacrificial anode reference device used for an offshore platform. Background Art

[0002] A sacrificial anode reference device is a device used to protect metal structures from corrosion. It usually consists of one or more sacrificial anodes and a reference electrode. The sacrificial anode is a highly active metal, such as zinc or aluminum, which undergoes an electrochemical reaction when in contact with an electrolyte, thereby protecting the structure. The reference electrode is used to monitor the corrosion of the anode so that the anode can be replaced or maintained in a timely manner. The use of sacrificial anode reference devices on offshore platforms can effectively extend the service life of the structure and reduce maintenance costs. This device is suitable for metal structures in an environment with conductive liquids such as seawater, such as offshore platforms, ships, bridges, etc. By regularly checking and replacing the anodes, it can be ensured that the structure is always effectively protected and the risk of corrosion damage is reduced.

[0003] In the existing sacrificial anode reference device for offshore platforms, in order to avoid mutual interference between the anode and the reference electrode, the reference electrode is usually fixedly installed near the sacrificial anode during use. When the reference electrode is regularly inspected or replaced, it needs to be disassembled. However, the disassembly process of the existing reference device is relatively cumbersome and has the disadvantage of being inconvenient to disassemble. Utility Model Content

[0012] (III) Beneficial effects

[0013] The utility model provides a sacrificial anode reference device for an offshore platform, which has the following beneficial effects:

[0014] 1. A sacrificial anode reference device for an offshore platform has the effect of being easy to disassemble and assemble in a reference device through the arrangement of a fixed block, an insert block, a clamp block, a clamping slot and a top block. When in use, during the installation of the reference device, the insert blocks on both sides of the mounting frame are inserted into the slots on the inner side of the fixed block. During the insertion process, the clamp blocks protruding from the sides of the insert blocks are blocked by the slots, so that the clamp blocks are squeezed into the grooves. The first spring is compressed, and after the insert block is completely inserted into the slot, the position of the clamp block is compared with the clamping slot. At this time, the first spring releases its elastic potential energy, so that the clamp block pops outward, and the clamp block is clamped into the clamping slot. At this time, the installation of the mounting frame is completed, and then the staff turns the threaded push rod to the right to move the thread of the threaded push rod downward, so that the stop block moves downward, and the conductive sheet is pressed by the stop block so that the other side of the conductive sheet is in close contact with the main body of the offshore platform. The electrode is connected to the electrochemical monitoring instrument through a second wire, and the sacrificial anode is also connected to the electrochemical monitoring instrument through a wire. The potential difference between the anode and the reference electrode is detected by the electrochemical monitoring instrument to understand the corrosion of the anode. Usually, the potential of the anode should be maintained at a stable level, indicating that the anode is working normally. According to the monitored potential difference, the anode can be adjusted, such as replacing a damaged anode or increasing the number of anodes to ensure that the metal structure is effectively protected. When the reference electrode needs to be checked regularly, during the removal of the reference electrode, the staff first turns the threaded push rod to the left to separate the stop block from the conductive sheet, and then presses the pressing blocks on both sides at the same time to make the push block slide in the slot, and the block stuck in the slot is pushed out by the push block. At this time, the mounting frame can be moved upward to complete the disassembly. The operation is simple and convenient, which is convenient for regular inspection and achieves the purpose of improving the convenience of inspection. BRIEF DESCRIPTION OF THE DRAWINGS
