The invention discloses a propeller device for an unmanned ship, and relates to the technical field of propellers. Comprising a propeller shell, a driving motor arranged in a cavity of the propeller shell, a gear box connected with the output end of the driving motor and rotating blades connected with the other end of the gear box. The water inlet is formed in the side wall of the propeller shell, multiple sets of anti-winding sleeves and guide inner rods are arranged in a cavity of the water inlet, the guide inner rods are sleeved with the anti-winding sleeves, and threaded grooves are formed in the outer walls of the guide inner rods. The multiple sets of anti-winding sleeves arranged at intervals are arranged at the water inlet, the guide inner rods are arranged in the anti-winding sleeves, under driving of the electric lead screws, the anti-winding sleeves can move along the outer portions of the guide inner rods, meanwhile, the anti-winding sleeves are in a rotating propelling state through the moving blocks and the threaded grooves, and the anti-winding sleeves can rotate through rotation of the anti-winding sleeves; the possibility that a fishing line and a silk thread penetrate through a gap to enter the rotating paddle is greatly reduced, and the anti-winding capacity of the propeller is improved to a certain degree.
本发明公开了一种无人船用推进器装置,涉及推进器技术领域。包括:推进器外壳、推进器外壳腔内设置的驱动电机、驱动电机输出端连接的齿轮箱以及齿轮箱另一端连接的旋转桨叶;还包括:进水口,开设在推进器外壳的侧壁,进水口的腔内设有多组防缠套筒以及导向内杆,且防缠套筒套设在导向内杆外,导向内杆外壁开设有螺纹凹槽。本发明在进水口处设置了多组间距排列的防缠套筒,且在防缠套筒内设置了导向内杆,在电动丝杆的驱动下,使防缠套筒可沿导向内杆的外部移动的同时,利用移动块以及螺纹凹槽,使防缠套筒呈旋转的推进状态,通过防缠套筒的旋转,极大的降低鱼线以及丝线穿过缝隙进入至旋转桨叶处的可能,一定程度上提高推进器的防缠绕能力。
