Offshore platform sacrificial anode current monitoring probe

Abstract

The invention discloses an offshore platform sacrificial anode current monitoring probe and belongs to the field of marine electrochemical sensors. The offshore platform sacrificial anode current monitoring probe comprises an outer flange bin, an L-shaped steel rod and a current monitoring unit. The outer flange bin comprises an upper blind flange and a lower flange bin. The L-shaped steel rod isconnected with the top face of the upper blind flange. The current monitoring unit is located in the flange bin. The current monitoring unit comprises a monitoring box, a spring ejector pin, a T-shaped electrode and a current monitoring sensor. The T-shaped electrode comprises an upper end and a lower end which are fixedly connected. The tail portion of the spring ejector pin is fixedly connectedwith the upper blind flange. The spring pin head of the spring ejector pin is connected with the upper end of the T-shaped electrode. The lower end of the T-shaped electrode is connected with the current monitoring sensor. The offshore platform sacrificial anode current monitoring probe can monitor the current given out by the sacrificial anode online in real time and monitor the consumption stateof the sacrificial anode. The offshore platform sacrificial anode current monitoring probe is suitable for monitoring cathode protective systems of various types of ocean engineering equipment and has important reference value in the aspects of monitoring, evaluating and maintaining the cathode protective systems and prolonging the service lives of the cathode 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 hulls. Generally, the amount of sacrificial anode is determined according to the relevant design parameters at 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 life-cycle monitoring 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 technical level for on-site installation. Contents o...
