Antifouling apparatus based on water jet and antifouling method thereof

The invention discloses an antifouling apparatus based on a water jet and an antifouling method thereof. The antifouling apparatus based on a water jet includes a hydraulic unit, and an antifouling film connected to the hydraulic unit, wherein a pipeline for conveying water is arranged in the antifouling film; an inlet of the pipeline is connected with the hydraulic unit; an outlet of the pipelineis located on the upper surface of the antifouling film and jet orifices are formed in the upper surface of the antifouling film; the hydraulic unit comprises a water tank, a motor and a water pump connected to the water tank; the motor drives the water pump to transport the water in the water tank to the pipeline in the anti-fouling film, and then the water in the pipeline flows out from the jetorifices to form a water jet; and the diameter of the jet orifice and the distance between the jet orifices are smaller than the size of a marine organism. The antifouling apparatus based on a waterjet prevents the marine org
