Convenient-to-store large-pipe-diameter flow channel detection device

The invention relates to the technical field of flow channel detection, in particular to a large-pipe-diameter flow channel detection device convenient to store, which comprises a main body component, a detection component, a bearing component arranged outside the detection component, a supporting component connected with the bearing component, and a functional component arranged in the supporting component; the locking part comprises an output assembly arranged in the bearing assembly and a limiting assembly abutting against the output assembly, the interior of the large-pipe-diameter flow channel is subjected to photographing detection through the detection assembly, the bearing assembly is matched with the supporting assembly, and therefore the detection assembly can move on the supporting assembly and the bearing assembly; the detection assembly is more stable in the moving process, the detection quality of the detection assembly can be improved, the functional assembly is matched with the output assembly
