A riverway trash blocking and cleaning device for a dam

Abstract

The application discloses a river trash blocking and cleaning device for a dam and belongs to the technical field of dam cleaning. The device comprises a trash blocking grid, a moving track, a grab bucket assembly and a tension detection assembly. The trash blocking grid is arranged on the inner side of the dam. The moving track is arranged above the dam and along the length direction of the trash blocking grid. The grab bucket assembly is arranged on the moving track and can move along the moving track. The tension detection assembly comprises a tension rope, floating objects, a supporting assembly, a first tension detection device and a second tension detection device. The device can monitor the sundries collected in front of the trash blocking grid in real time by using the tension detection assembly. When the tension change value of the tension rope reaches a preset value, the grab bucket assembly can quickly and accurately move to the position to be cleaned through the moving track, and the sundries in front of the trash blocking grid can be cleaned. The device is rationally designed, can timely and accurately monitor the accumulation of the sundries at the trash blocking grid, and can efficiently clean, so that the safe and stable operation of the rear-end equipment is ensured.
