The invention belongs to the field of marine organism fouling protection, and particularly relates to an electricity-free controlled release type self-driven anti-fouling device, a main body structure comprises a frame plate, a plurality of cathode plates and anode plates, the cathode plates and the anode plates are arranged on the frame plate at intervals, and insulation sealing materials are further arranged between the frame plate and the cathode plates and between the frame plate and the anode plates. The anode is driven to accelerate dissolution by utilizing a large potential difference of two materials, namely a high-potential oxide and a hybridized copper alloy, in seawater, so that the anode autonomously releases multiple antifouling components such as copper ions, silver ions and capsaicin, and an effective antifouling concentration is achieved in a certain water area range; effective anti-fouling is carried out on complex local structures such as a seawater passing cabin, a small aircraft permeable structure and a high-precision movement mechanism in marine equipment, the anti-fouling agent release rate, the anti-fouling service life and the structural form can be designed according to the environment where a protected structure is located, an external power source is not needed, and the anti-fouling device is suitable for water depth changes. The problem of accelerated corrosion caused by contact with dissimilar metal of other structures is solved, the involved engineering is small, and installation and replacement are convenient.
