Crack detection equipment for box dam and use method of crack detection equipment

The invention belongs to the technical field of box dam crack detection, and particularly relates to a crack detection device for a box dam and a use method thereof.The crack detection device comprises a detection body and an azimuth steering mechanism arranged on the detection body and further comprises a multi-direction dam body crack detection mechanism and a crack detection auxiliary mechanism; the multi-direction dam body crack detection mechanism is arranged on the detection main body, and the crack detection auxiliary mechanism is arranged on the multi-direction dam body crack detection mechanism; the invention provides a multi-direction dam body crack detection mechanism, and the comprehensive coverage of the slope surface can be realized by combining the detection in the horizontal direction and the detection in the vertical direction. The detection in the horizontal direction is helpful for detecting the crack horizontally extending along the slope, and the detection in the vertical direction is mor
