Research and design of the hydraulic system for raising and lowering the saltwater barrier gates in Bình Định province

Abstract

Currently, the majority of saltwater barrier dams use manual ball screw mechanisms or electric motors for dam gate raising and lowering operations. These methods have several limitations, such as dependence on human subjectivity, improper dam gate raising and lowering processes, and the risk of main shaft deformation, leading to damage to the ball screw gearbox mechanisms. To address these issues, the use of hydraulic cylinders has been proposed by the author in this paper. Based on actual data, the author has designed a hydraulic system for operating the dam gate raising and lowering of saltwater barrier dams in Binh Dinh province. Simulation results demonstrate that the system not only meets technical requirements but is also economically efficient, overcoming previous operational limitations. This solution not only improves operational quality but also paves the way for adopting new technologies to automate and enable remote monitoring during the operation of similar irrigation dams.
