Silt traps are typically installed at the intake of the equipment, primarily to prevent debris such as branches, weeds, floating objects, and aquatic plants from entering gates, valves, turbines, etc., thereby protecting the equipment from damage and ensuring the normal operation of power generation facilities. In hydropower plants, there are usually two silt traps: one is a floating silt trap, usually located upstream near the intake, which can float up and down with the water level; the other is a fixed silt trap (removable), usually placed at the intake. During operation, it is important to clean the debris on the silt traps promptly to minimize water energy loss and prevent the silt traps from being collapsed by debris. In conjunction with the scheduled maintenance shutdown of the equipment, the silt traps should be inspected and repaired, including checking for any loose or deformed grating, welding issues, and whether the zinc coating or paint on the metal surface has peeled off or rusted, and timely anti-corrosion treatment should be applied. Generally, maintenance is required every 3 to 5 years.
