Description

Technical Field

[0001] This utility model relates to the field of potential measuring instruments, and in particular to a movable support for a potential measuring instrument. Background Technology

[0002] The jacket is a critical facility ensuring the normal operation, structural stability, and robustness of offshore platforms. Its role is comparable to the foundation of a building, playing a vital part in the overall stability of the platform. To guarantee the long-term safety of the jacket, a cathodic protection system is specifically designed. Its core purpose is to effectively protect the jacket through an electrolytic reaction, preventing the extensive adhesion of marine organisms that could lead to severe corrosion and thus affect the platform's stability and structural integrity. A potentiometer is an important tool for monitoring the performance of the cathodic protection system. By accurately measuring and comparing voltage and current values, it determines whether the cathodic protection device is functioning correctly, ensuring that the jacket remains in good health at all times.

[0003] However, because the measuring components of the potentiometer need to be placed in seawater, and the differences in the measuring points require the use of extension rods to continuously adjust the length, these extension rods are usually made of metal with a smooth surface. This makes them extremely easy for operators to lose their grip while holding the device, potentially causing the entire equipment to fall into the sea. Each adjustment of length and gripping involves significant risk; therefore, safe operation in this stage is paramount. Utility Model Content
