Description

Technical Field

[0002] Water conservancy engineering river gates are engineering structures used in rivers, lakes, reservoirs and other water bodies for the purpose of controlling water flow, regulating water levels, flood control and drainage, irrigation and navigation. They are an indispensable part of water conservancy projects and have various types and functions.

[0003] However, traditional river gates used in water conservancy projects still have certain defects.
