漩涡式垃圾收集装置造涡构件桨叶设计分析

Design and Analysis of Vortex-forming Component of the Vortex Garbage Collection Device

结合螺旋桨在水中旋转带动流体运动产生漩涡的原理,提出漩涡式造涡构件,并应用于水上垃圾收集装置,借助螺旋桨的升力线理论对造涡构件进行结构设计,根据设计尺寸进行三维建模,针对不同工况,采用ANSYS软件流体计算模块分析相同角度下叶片数量对造涡构件的受力影响以及相同叶片数量下不同叶片角度对造涡构件的受力影响,采用结构静力学模块进行结构强度分析校核,结果表明,在有外管架结构下,选择3片桨叶作为产生漩涡的造涡构件较为合理,选择叶片角度为45°的效果最好。

Combining with the principle of vortex generated by fluid movement driven by propeller rotating in water,vortex type vortex-forming component was proposed and applied in garbage collection device.Based on the theory of lift line of propeller,the vortex component was designed and 3-dimensional model was established.Under different load conditions,the fluid calculation module of ANSYS was used to analyze the influence of the number of blades at the same angle upon the force of the vortex-forming component,and the influence of different blade angles upon the force at the same number of blades.The structural statics module of ANSYS was applied to analyze and assess the structural strength of the vortex-forming component.The results showed that it is the most reasonable to choose three blades as the vortex-forming component under the structure of outer pipe frame,and the member structure with blade angle of 45°is the most suitable to work.
