Abstract

The invention provides an offshore wind power foundation cathode protection remote monitoring device and method, and belongs to the field of offshore engineering structure cathode protection and detection. The device comprises cathode protection monitoring hosts, testing cables, liquid level sensors, floating type electric potential sensors, fixed type electric potential sensors and testing piles. Each testing assembly is formed by the corresponding testing pile, the corresponding liquid level sensor, the corresponding floating type electric potential sensor and the corresponding fixed type electric potential sensor, wherein the liquid level sensor, the floating type electric potential sensor and the fixed type electric potential sensor are arranged on the testing pile. The cathode protection monitoring hosts are correspondingly distributed in offshore wind power tower drums. Each cathode protection monitoring host is connected to the corresponding testing assembly and a corresponding offshore wind power foundation though the corresponding testing cable. According to the offshore wind power foundation cathode protection remote monitoring device and method, cathode protection electric potential data of a tide level change area can be accurately obtained in real time through the floating type electric potential sensors and the liquid level sensors, and the wind power foundation cathode protection effect assessment accuracy is effectively improved. The offshore wind power foundation cathode protection remote monitoring device has the beneficial effects of being simple in structure, easy and convenient to operate, high in universality and the like and is suitable for cathode protection effect monitoring of various offshore engineering structures.

Description
