THE CENTERING CONTROL WITH BUOYANCY ROOM TYPE MOVABLE DAM(GATE)

摘要

It is related to the hydrology applied to the beams of rivers and rivers, and the buoyancy chamber variable movable language (automatic flood gate = hereinafter referred to as hydrology), which is blocking the waterway by its own weight, has the buoyancy and hydraulic pressure as the upstream water level rises. It is a water gate designed to maintain constant water level without artificial operation by automatically opening up the waterway to a certain height and opening the waterway, and then lowering the upstream water level, thereby reducing the buoyancy and water pressure and closing the waterway again by its own weight.;In the water gate 10 which is installed transversely inside the water port formed so as to control the flow of water and automatically elevates from the water port by buoyancy and water pressure, and opens and closes the water port, The guide rail 20 provided on the inner wall of the water passage to guide the lifting operation, the guide roller 30 provided on both sides of the water gate 10 against the guide rail 20 and the buoyancy can be adjusted. It is composed of a fixed buoyancy chamber 40, the variable position buoyancy chamber 50 and the lifting device 60 that can change the position of the variable position buoyancy chamber 50 provided in the door up and down.
