Gully type debris flow starting simulation test device

The invention provides a gully-type debris flow starting simulation test device, and belongs to the technical field of debris flow simulation tests, and the gully-type debris flow starting simulation test device comprises a gully basin assembly and a longitudinal slope large assembly. The sliding angle of the gully side supporting shaft is controlled through the gully-shaped cylinder, the local gully opening contour of the gully drainage basin is simulated, the overall rotation of the gully bottom supporting shaft and the gully side supporting shaft is controlled through the torque motor, and cutting and bending of the gully drainage basin are simulated. The lower surface of the gully opening belt is attached to the surfaces of the gully bottom supporting shaft and the gully side supporting shafts, the cloth tensioning motor controls the releasing amount of the gully opening belt, the tensioning of the gully opening belt is adjusted, deformation simulation of the gully opening belt on the gully valley is faci
