The invention discloses an unmanned ship carbon fiber protective device based on wind and wave resistance, and relates to the technical field of an unmanned ship, which comprises an unmanned ship body; a stable protection mechanism is installed on the upper surface of the unmanned ship body, a diversion anti-tilting mechanism is installed on the bottom of the unmanned ship body; the stable protection mechanism comprises a floating tank, a fixing plate, a fixing tank, a first electrohydraulic push rod, a through hole, a pushing column, a pumping-in pipe, a pumping-out pipe, an electric push rod, a pushing rod, a push-pulling rod and a water pump. According to a carbon fiber protective device for an unmanned ship based on wind and wave resistance, the streamline plate can make the unmanned ship sail steadily, can avoid the problem of swinging left and right during the voyage, The height of the floating tank is lowered by extending the telescopic end of the electric push rod, so that thedevice is more stable, the problem of the device rollover caused by the wind on the side of the unmanned ship body can be avoided, the stability and the anti-tilting ability of the device are improved, and the unmanned ship body is better protected.
