The invention relates to a guide pipe paddle supporting partition prewhirl flow guide device. The device comprises a propeller hub, a plurality of propeller supports are uniformly distributed on the wall surface of the propeller hub along the circumferential direction; the outer ends of the propeller supports are jointly provided with a guide pipe, the end of a single propeller support is fixedlyconnected with the guide pipe, the middles of the propeller supports located between the propeller hub and the guide pipe are jointly provided with a flow guide ring in an embedded mode, the propellerhub, the flow guide ring and the guide pipe are axially concentric, and flow guide pieces are installed on the flow guide ring located between the adjacent propeller supports in the radial direction;the flow deflector comprises an inner guide vane and an outer guide vane which are located at the two ends, and a movable guide vane is rotationally installed between the outer guide vane and the inner guide vane. The movable guide vane is driven by the adjusting mechanism to deflect relative to the inner guide vane and the outer guide vane. By installing the prewhirl flow guide device, especially the adjustable flow guide pieces, flexible adjustment of the flow field uniformity is achieved, the propelling efficiency is improved, the vibration and cavitation performance is greatly improved, and the strength of the whole structure is effectively enhanced.
本发明涉及导管桨支撑分区预旋导流装置,包括桨毂,桨毂壁面上沿着周向均布有多个桨支撑,多个桨支撑外端头共同安装有导管,单个桨支撑端部与导管固装,位于桨毂与导管之间的多个桨支撑中部共同嵌装有导流环,桨毂、导流环和导管轴向同心,位于相邻桨支撑之间的导流环上沿着径向安装有导流片;导流片包括位于两端端头的内导叶和外导叶,外导叶和内导叶之间转动安装有活动导叶;活动导叶在调节机构带动下相对于内导叶、外导叶偏转;本发明通过安装预旋导流装置,尤其是可调节的导流片,实现流场均匀性的灵活调整,不仅提高了推进效率,亦大大改善了振动和空泡性能,并有效加强了整体结构的强度。
