南水北调中线干渠边坡藻类清除装置设计
Design of Algae Removal Device for Slopes of South-to-North Water Diversion Mainline Canal
摘要

南水北调是一个非常重要的工程, 它的建设对于解决中国北方缺水问题, 促进经济发展, 改善民生等方面都有着重要的意义, 但其也面临着一些环境问题, 例如边坡藻类时刻影响着南水北调的水质情况。本文主要围绕边坡藻类的清除, 设计了一款边坡除藻设备, 该设备在牵引车的驱动下带动清除机构进行藻类的清除工作, 根据藻类的结构特点和空化射流除藻的除藻效果, 采用空化射流的方法对南水北调边坡的藻类进行有效清除。本文首先进行机构履带底盘、机械臂和清除机构的设计, 然后采用软件Solidworks对机械臂进行建模, 并进行整体设备的装配。通过对装配图的动画仿真表明机构运转过程中无干涉现象, 运动轨迹和状态符合预期。通过ANSYS对机械臂进行静力分析和模态分析, 在静力分析中, 施加自身重力和前端拉力后, 结果表明机械臂的最大位移变形符合变形要求, 同时最大应力小于材料的屈服极限; 通过模态分析中六阶模态的振动频率估计出整机振动频率的振动范围, 从而完成对边坡除藻装置清除机构的设计。

Abstract

South-to-North Water Diversion is a very important project, and its construction is important for solving the problem of water shortage in northern China, promoting economic development, and improving people's livelihood. However, it also faces some environmental problems, such as algae on the side slopes which always affect the water quality of the South-to-North Water Diversion. This paper mainly focuses on the removal of algae on the slope, designs a slope algae removal equipment, the equipment in the tractor drive to drive the removal mechanism for the removal of algae, according to the structural characteristics of algae and cavitation jet de-algae algae removal effect, the use of cavitation jet method of the South-to-North Water Diversion of algae on the slope of the slope for effective removal. In this paper, we first carry out the design of institutional track chassis, mechanical arm and removal mechanism, and then use the software Solidworks to model the mechanical arm and carry out the assembly of the overall equipment. The animation simulation of the assembly diagram shows that there is no interference during the operation of the mechanism, and the motion trajectory and state are in line with expectations. Through ANSYS static analysis and modal analysis of the mechanical arm, in the static analysis, after applying its own gravity and frontend tension, the results show that the maximum displacement and deformation of the mechanical arm are in line with the deformation requirements, while the maximum stress is less than the yield limit of the material; through the modal analysis of the vibration frequency of the sixth-order modes estimate the vibration frequency of the vibration frequency of the whole machine vibration range, so as to complete the design of the slope algaecide removal device removing mechanism.
