[0002] In water conservancy projects, trash racks are important facilities widely used in various water conservancy hubs, hydropower stations, pumping stations, and water intakes. Their main purpose is to prevent floating debris and impurities from entering the deeper layers of rivers, lakes, and reservoirs, protecting water quality, maintaining the ecological environment, and ensuring the safety and normal operation of water conservancy infrastructure. These devices play a vital role in various water conservancy projects such as drainage systems, irrigation canals, and hydropower stations. However, traditional water conservancy trash racks are prone to clogging by accumulated media and debris, affecting water flow. Furthermore, cleaning existing trash racks often requires manual labor or complex mechanical equipment. Manual cleaning is not only labor-intensive and inefficient, but also poses significant safety risks in situations with rapid water flow and harsh environments. Therefore, we propose a new type of water conservancy trash rack to address these problems. Summary of the Invention
