A gravity counteracting roller shutter type full-automatic stepless layered water taking beam gate device and control method

Abstract

This invention relates to an anti-gravity roller shutter type fully automatic stepless layered water intake gate device and control method. A gate slot is created on the concrete pier of the hydropower station's water intake facing the water flow. The device also includes several gate panels connected by a flexible structure to form a gate assembly. The direction perpendicular to the water surface is defined as the Y-axis, and the direction parallel to the water surface as the X-axis. When the gate assembly functions as a water-blocking device, it is positioned along the Y-axis. A drive wheel is installed on the X-axis, and a steering wheel is installed at the origin of the coordinate system. One end of the gate assembly is embedded in the gate slot via the steering wheel, and the other end is connected to the drive wheel. The rotation of the drive wheel causes one end of the gate assembly to slide up and down along the Y-axis within the gate slot, thus opening the gate assembly. This invention achieves water temperature regulation without relying on gravity to drive the gate assembly's opening and closing. It also features a simple structure, reduces the risk of gate jamming, and is easy to maintain.
