[0002] Bridge drainage is an indispensable part of bridge design and maintenance. Its main purpose is to quickly remove water from the bridge surface, prevent rainwater from accumulating and seeping into the beams, and protect the durability and safety of the bridge. In some narrow areas, drainage devices need to be installed to achieve smooth drainage of the bridge.

[0003] Although today's drainage devices can achieve the purpose of drainage, the water body generally carries a large amount of impurities such as mud and sand. During drainage, blockage is very likely to occur, affecting the smoothness of drainage. In addition, some mud and sand will be deposited inside the drainage device during the drainage process, which is difficult to clean and the actual application effect is not good. In order to solve the above problems, there is an urgent need for an anti-blocking device suitable for bridge drainage. Utility Model Content
