A New Design of Damless Water Intake System

To make up for the structural defects of the existing damless water intake systems and improve their engineering design qualities,a new damless water intake system is designed according to the principles of mechanics,mechanism and electricity. By means of some simple mechanical components,this new system realizes the purposes of mechanical transmission and hydraulic water intake,reduces the requirements of flow and sediment conditions for the intake site selection and avoids the damages to the integrity and stability of the original riverbank by the water intake construction. Through sharing the middle sidewalls of the double helix channel,the construction cost of the grit chamber is reduced and its centralized land occupation is also convenient for the layout. Based on the characteristics of double helix geometry shape,bend flow movement and sediment deposition,the efficiency of sediment deposition is improved by the energy dissipation of bend helix flow.
