A hedging clearing method for a full-rotation tug propeller comprises the following steps that a, when propellers work abnormally, the two propellers on a stern side of the tug are stopped, and the properties, types and specific clamping positions of foreign matters are observed; b, a broadside of the tug is berthed to a fixed wharf, and the position, where no foreign matter is clamped, of the propeller is close to the fixed wharf; c, the tug is moored on the fixed wharf through mooring equipment, and safety is ensured; d, the two propellers are adjusted to the positions in the ship; and e, the propeller close to the fixed wharf side is started, the propeller on the outer side of the fixed wharf is driven to rotate reversely through a generated strong impact force, and foreign matters aregradually loosened and flushed away by a water flow. Through opposite flushing of the two propellers, the foreign matters clamped at one of the propellers are removed and taken away by the water flow,the method does not need additional expenses, only starting operation of the ship is needed, the cost is saved, and meanwhile, the method is very timely in cleaning.

    一种全回转拖轮螺旋桨的对冲清除方法,包括以下步骤:a、出现螺旋桨工作异常时,将拖轮的船尾侧的两台螺旋桨停机,并观测异物的性质、种类及具体卡入的位置;b、将拖轮的舷侧靠泊到固定码头上,其中,未卡入异物的螺旋桨的位置与固定码头靠近;c、通过系泊设备将拖轮系泊在固定码头上并确保安全;d、将两台螺旋桨都调整至船中的位置;e、将靠近固定码头侧的螺旋桨启动,通过产生的强大冲击力带动固定码头外侧的螺旋桨反向转动,使得异物逐渐松脱并被水流冲走;通过两个螺旋桨的对冲,使得卡在其中一个螺旋桨处的异物被清除并被水流带走,该方法不需要另外的费用,只需船舶自己开机操作就可以,节约成本,同时,该方法的清理非常及时。
