Comprehensive monitoring protection device for impressed current cathodic protection system and implementation method of comprehensive monitoring protection device

Abstract

The invention discloses a comprehensive monitoring protection device for an impressed current cathodic protection system. The comprehensive monitoring protection device comprises a protection box, a cathodic protection monitoring unit, an environment monitoring unit, a data collecting and processing unit, an auxiliary supporting unit and a safety monitoring unit; and the cathodic protection monitoring unit, the environment monitoring unit, the data collecting and processing unit, the auxiliary supporting unit and the safety monitoring unit are installed in the protection box. On the basis of ensuring the anti-corrosion effect of the monitoring protection device itself and a direct-current power supply and timely early warning of abnormity, the running state of the impressed current system can be monitored online in real time, and timely early warning can be carried out so as to take treatment measures as soon as possible; and system faults or failures caused by factors such as corrosion damage, mechanical damage or man-made damage are avoided or slowed down, the cathodic protection effect is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cathodic protection, in particular to a comprehensive monitoring protection device for an impressed current cathodic protection system and an implementation method thereof. Background technique [0002] Impressed current cathodic protection systems are widely used in marine engineering anticorrosion, such as seaport terminals, cross-sea bridges, offshore platforms, etc. The structure of the impressed current system is complex, including DC power supply, auxiliary anode, reference electrode, cable and other components. When the impressed current system is in service in the marine environment, it is vulnerable to corrosion, wave erosion, and mechanical damage, which will cause corrosion damage or abnormal function of the components, resulting in failure of the impressed current system and failure to operate normally. [0003] Regular manual testing of the impressed current system is usually performed in or...

AI Technical Summary

Problems solved by technology

However, different components of the impressed current system are arranged in different parts of the offshore engineering structure, some parts (such as the bottom of the wharf, offshore wind power foundation) are not easy to reach, manual detection is time-consuming, labor-intensive, and the workload is large, and it is difficult to achieve continuous monitoring. It is easy to cause fault warning and untimely processing

[0004]Some impressed current systems have monitoring functions, but the monitoring parameters mainly include the output current and output voltage of the DC power supply or the protection potential of the protected steel structure, and the external The monitoring function of the current system is easily affected by system failures, and it is difficult to fully and continuously reflect the overall operating status of the impressed current system and achieve timely and effective control

[0005]At the same time, due to the complex circuit of the DC power supply and the large number of electronic components, if the protection is insufficient, it is more likely to cause corrosion damage or abnormal system function than other components

In addition, when the DC power supply is placed on the job site (such as the wharf), due to the complex operating conditions and personnel conditions, it may cause unforeseen mechanical damage or man-made damage, which will affect the normal operation of the impressed current system.
