An ocean platform sacrificial anode current monitoring probe

Abstract

The invention discloses a sacrificial anode current monitoring probe for an offshore platform, belonging to the field of marine electrochemical sensors. The probe comprises an outer flange cabin, an L-shaped steel rod and a current monitoring unit; the outer flange cabin includes an upper flange cover and a lower flange cabin; L-shaped steel rod is connected to the top surface of the upper flange cover; the current monitoring unit is located inside the flange cabin; the current monitoring unit includes a monitoring box, a spring thimble, a T-shaped electrode and a current monitoring sensor; the T-shaped electrode includes the upper end and the lower end The upper end and the lower end are fixedly connected; the tail of the pogo pin is fixedly connected with the upper flange cover, the pogo pin head of the pogo pin is connected with the upper end of the T-shaped electrode, and the lower end of the T-shaped electrode is connected with the current monitoring sensor. The device can monitor the current emitted by the sacrificial anode online and in real time, and monitor the consumption state of the sacrificial anode. It is suitable for monitoring cathodic protection systems of various types of marine engineering equipment, and has important reference value for monitoring, evaluation, maintenance and life extension of cathodic protection systems. .

Description

technical field [0001] The invention relates to the field of marine electrochemical sensors, in particular to an ocean platform sacrificial anode current monitoring probe. Background technique [0002] In the field of marine engineering, in order to protect marine engineering equipment from being corroded by seawater, sacrificial anodes are usually used to protect offshore platforms or ship hulls. Generally, the amount of sacrificial anode is determined according to relevant design parameters in the early stage of design, and the actual current of sacrificial anode is very important in the whole design stage and working stage. Carry out the monitoring of the whole life cycle, and grasp the current of the sacrificial anode in real time to determine whether the cathodic protection system is working normally. However, the existing current monitoring probe has a complex internal structure and complicated internal wiring, which requires a high level of on-site installation techn...
