Design of Algae Removal Device for Slopes of South-to-North Water Diversion Mainline Canal

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.
