The invention relates to a double-propeller propelling device of a ship. The double-propeller propelling device is characterized by comprising a ship body, a fixing plate, a bush set, a transmission unit and a propeller module. According to the device disclosed by the invention, a first paddle blade or a second paddle blade can be properly selected for propelling according to the depth of seawater, so that the problems that the existing marine propeller cannot stretch up and down, cannot effectively adapt to complex terrains, and cannot be properly adjusted for a navigation area with large draft change so as to cause poor drawing force, slow navigational speed and weak wind resistance and easily damage the propeller can be solved; and the propellers are arranged on each of the two sides below the tail of the ship, one propeller rotates leftwards, and the other propeller rotates rightwards, so that the towing force of the advancing of the ship can be effectively improved through the arrangement mode so as to synchronously increase the navigational speed, the wind resistance is high, and the ship can keep power when one propeller breaks down so as to effectively improve the practicability.
本发明涉及一种船舶的双螺旋桨推进装置,其特征在于:包括船舶本体,固定板,套筒组,传动单元和螺旋桨模块;本发明本装置可根据海水的深浅选用适当的第一桨叶或第二桨叶进行推进,这样避免现有的船用螺旋桨无法上下伸缩,不能有效适应复杂地形,对于吃水变化大的航区不能适当调节,使得拖力差,航速慢,抗风力弱,并且容易使得螺旋桨损坏,并且该装置在船尾下方两侧各装一个螺旋桨,一个螺旋桨左转,另一个螺旋桨右转,这种设置方式可有效的提高船舶前进的拖力,进而航速跟着同步提高,并且抗风力较强,在其中一个螺旋桨出现故障时还能使船舶保持动力,有效的提高了实用性。
