The invention belongs to the technical field of marine guide pipes, and particularly relates to a high-performance marine rotary flow guide pipe which comprises a rotary tail shaft, a guide pipe, a flow guide pipe and a flow guide pipe. The main shaft is arranged in the end, away from the ship body, of the rotating tail shaft, and a driving mechanism is arranged in the rotating tail shaft and used for driving the main shaft to rotate; the propeller is fixedly connected with the surface of the main shaft; the mounting plate is fixedly connected with the surface of the rotating tail shaft; when the load of the propeller is reduced, the motor is started again, the output shaft of the motor rotates reversely to be matched with the threaded driving rod to drive the first fixing lug, the guide pipe body and the second fixing lug to reset and be far away from the propeller, and therefore the situation that the sailing resistance is increased after the load is reduced is avoided; the efficiency is reduced, and the fuel consumption is increased, so that the guide pipe main body can ensure that the propeller can run well under various negative loads.
本发明属于船用导管技术领域,具体的说是一种高性能船用转动导流管,包括:转动尾轴,所述转动尾轴的一端设置于船体的内部;主轴,所述主轴设置于转动尾轴远离船体一端的内部,且所述转动尾轴内设置有驱动机构,用于驱动主轴转动;螺旋桨,所述螺旋桨与主轴的表面固定连接;安装板,所述安装板与转动尾轴的表面固定连接;提升螺旋桨在重载工况下的效率,而当螺旋桨负荷减小后,再次启动电机,电机的输出轴反转与螺纹驱动杆配合带动固定耳一、导管主体和固定耳二复位,远离螺旋桨,从而实现避免负荷减小后,反而增加航行阻力,降低效率增加燃油消耗量的现象,使得本发明中的导管主体能在各种负载荷下保证螺旋桨能良好的运转。
