[0002] After searching, Chinese Patent No. 202122400359.6 discloses a river surface pollution interception device for water conservancy projects. The device cooperates with each other between multiple groups of structures, so that the rotating rod drives the front and rear two groups of rotating disks to rotate in opposite directions through the cooperation of the active bevel gear and the driven bevel gear. The rotating disk drives the stirring plate to rotate, thereby blocking and stirring the silt and dirt inside the river channel, thereby further improving the stirring effect of the device on the silt inside the river channel and reducing the probability of large silt and dirt remaining.
