The rotating card plate is rotatable. When in use, the rotating card plate can be rotated to insert the rotating card plate into the positioning socket. The rotating card plate fixes the telescopic length of the lower sliding rod and the upper sliding rod to prevent the two from sliding under force during flood control of water conservancy projects. When the impact force of the water flow is large, in order to improve the compressive effect of the flood control box and to prevent the flood control box from tilting during flood control of water conservancy projects, the telescopic rod composed of the lower sliding rod and the upper sliding rod can be extended, and the lower end of the lower sliding rod can be inserted into the dam to provide auxiliary support for the flood control box, thereby decomposing the thrust of the water flow on the flood control box. The U-shaped limit plate fixes the opening angle of the telescopic structure to prevent the telescopic rod from slipping on the dam, thereby ensuring the optimal supporting angle of the telescopic rod to the flood control box.
