Cathode protection mounting structure and offshore wind power equipment

The utility model discloses a cathodic protection installation structure and offshore wind power equipment, the cathodic protection installation structure comprises a vertical pile, a composite cable and an electrode assembly, the technical scheme of the utility model is that a plurality of cables are wrapped by the composite cable, so that the cables are arranged outside the vertical pile and can bear more pressure; the cable is prevented from being broken or stretched due to stress and affecting transmission of current signals, and the composite cable is detachably limited on the side face of the vertical pile through the fixing piece and the crystal stretching structure, so that when the cable needs to be replaced and maintained, the composite cable is directly replaced, maintenance can be achieved, the construction operation process is simplified, and the construction efficiency is improved. The maintenance difficulty and cost are greatly reduced, the maintenance effect is improved, and the construction q
