And it must be installed before the steel structure of the pile body or the berthing corbel has not entered the sea. The installation project is huge, involving heavy weight and large volume of the steel structure. The welding process requirements for the construction personnel on site are very high, and the construction requires the help of many people.
And later in the ocean, the maintenance is very inconvenient and the maintenance cost is expensive
Due to the large size and weight, it is prone to weld cracking and equipment damage

The invention relates to the technical field of impressed current cathodic protection, and discloses a cathodic protection fixing device for an offshore wind power steel structure. Reference electrode connection mechanism, the auxiliary anode connection mechanism includes a first flange, one side of the first flange is connected with a first flange joint, and a number of second flanges are opened at the edge of the first flange. screw hole. In the present invention, the first fixing nut is fixed on the second limiting groove, and the first flange and the auxiliary anode body are fixed, and at the same time, the auxiliary anode body and the first connecting wire are connected by the first connecting rod, so that they can be connected to the conductive , The position of the first connecting wire can be fixed by the first fixing piece. When the auxiliary anode body needs to be fixed, it is only necessary to fix the first fixing steel pipe, which greatly facilitates the installation or replacement of the staff.
Description
technical field [0001] The invention relates to the technical field of impressed current cathodic protection, in particular to an offshore wind power steel structure cathodic protection fixing device. Background technique [0002] Cathodic protection is an anti-corrosion measure that must be taken on offshore platforms. New offshore platforms usually adopt sacrificial anode cathodic protection. If the in-service offshore platform needs to extend the service time, but the sacrificial anode has been used up, the service time of the cathodic protection needs to be extended, and the sacrificial anode method cathodic protection method and the impressed current cathodic protection method can be used. Due to the high cost of installing sacrificial anodes underwater, the advantages of using impressed current cathodic protection are prominent. In the process of applied current protection, the auxiliary anode is connected to the positive pole of the DC power supply, and the current i...
