The hydraulic flap gate is a type of gate that combines hydraulic principles with water power to achieve automatic control. It is primarily used for water storage, flood discharge, and water level regulation in rivers, reservoirs, and other water bodies. Its key features include automated control, simple structure, and easy maintenance, making it widely applicable in urban flood control, agricultural irrigation, and other fields.
Structural Composition
It mainly consists of panels, legs, piers, connecting rods, and hydraulic cylinders. The panels are typically made of steel plates, while the legs and piers are used to secure the gate's position. The hydraulic cylinders control the opening and closing of the gate through extension and retraction.
Working Principle
Water Storage State: The hydraulic cylinder retracts, lifting the gate panel via the connecting rod to form a water-blocking angle, gradually raising the upstream water level.
Flood Discharge State: The hydraulic cylinder extends, pushing the gate to lie flat on the riverbed, allowing water to flow smoothly and achieve flood discharge.
Features and Advantages
Automated Control: Automatically adjusts based on upstream water levels without manual intervention.
Compact Structure: Few components and robust connections result in low maintenance costs.
Excellent Sealing Performance: The gate tightly seals with the riverbed and both sides, preventing water leakage.
Landscape Compatibility: When closed, it integrates seamlessly with the river channel without affecting the landscape.
Application Areas
Primarily used in urban flood control, agricultural irrigation, and river management scenarios, effectively regulating water levels and reducing flood risks.
