The invention relates to a ferrule light-body propeller annular water outlet thruster, which has the basic functions that an old exposed thick and heavy propeller is replaced by the ferrule light-body propeller, so that the ferrule light-body propeller is firmer, the water passing capacity is improved, and meanwhile, the winding of sundries can be prevented. An annular water drainage port device is additionally arranged on the rear portion of the propeller, and the water column-shaped water drainage shape of the propeller is changed into the annular water column-shaped water drainage shape, so that the water drainage strength of the propeller is increased, and the reverse thrust acting force in water is increased. Therefore, the sailing speed of the ship can be increased under the condition that power is not increased.
本发明涉及一种套圈轻体螺旋桨环形排水口推进器,其基本功能是,减除了老式裸露在外、厚实而笨重的螺旋桨,改变成为套圈轻体螺旋桨,使其更为结实又增大了通水能力,同时又可防止杂物的缠绕。在其后部加装的环形排水口装置,是将螺旋桨排出水柱形的排水形状,改变成了环形水柱形的排水形状,由此增大了螺旋桨的排水力度,和增大了水中的反推作用力。因此可以在不增加动力的情况下,加快了船舶的航行速度。
