Wave preventing method and breakwater system using wave preventing method

The invention discloses a wave preventing method including steps of wave elimination and energy consumption by a main mode of wave energy conversion, and further provides a breakwater system using the wave preventing method. In the system, the upper end of an annular two-way hydraulic damper is fixedly connected with a floater; parallel steering shafts are arranged on the front and back end surfaces of main floating bodies; the tail ends of the steering shafts are fixedly connected with a floater winding shaft; at least two blade connecting rods are linearly fixed on the left and right two sides of the main floating bodies; rotating shafts are rotationally connected between each pair of adjacent blade connecting rods; an anchor chain is mounted on the blade connecting rod at the lowest part, and is buckled with an anchor; blades are mounted between the left and right symmetric rotating shafts on all the main floating bodies; each pair of adjacent main floating bodies are spherically connected through spherica
