[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Low-head hydraulic structures that use gates to control flow and adjust water levels are built on rivers and channels. Closing the gates can block floods, block tides or raise upstream water levels to meet irrigation needs. , power generation, shipping, aquaculture, environmental protection, industrial and domestic water needs; opening the gate can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as buildings for retaining, discharging or taking water. The gates of existing small-scale water conservancy facilities are composed of gate plates and dam bodies. Most of the devices on both sides of the gate plates have filtering structures to block dead branches and debris in the water area. However, most of the existing gate filtering structures are fixedly installed on the gates, which makes it inconvenient for operators to clean and replace the filtering structures, bringing inconvenience to the operators' work.
