The invention discloses an unmanned ship structure suitable for a severe sea condition environment. The unmanned ship structure comprises an unmanned ship body, a ship body, a balance wing, a hollow groove, a stable heavy hammer, an automatic adjusting stabilizer, a holder, a
microcomputer controller, a first
servo motor, a first gear, a connecting shaft, an outer ring angle sensor, an outer ring,a second
servo motor, a second gear, an outer ring torquer, a third
servo motor, a third gear, a middle ring, a middle ring torquer, an inner ring, an inner ring angle sensor, an inner ring torquer,a rotor, a shell, a
tail balance wing and a
propeller; the ship body is installed on the unmanned ship body, the hollow groove is formed in the balance wing, the stable heavy hammer is installed at the
tail end of the balance wing, the automatic adjusting stabilizer is installed in the middle of the ship body, and the holder is installed on the automatic adjusting stabilizer. The unmanned ship structure has the advantages that the appearance is novel, the internal automatic adjusting stabilizer is small in size, light in weight, simple in structure and good in reliability, the running state ofan unmanned ship can be intelligently detected, automatic adjustment is achieved, and the stability of the unmanned ship in the course is kept.
