The utility model relates to the technical field of
water supply and drainage pipeline maintenance, and discloses a
water supply and drainage maintenance device which comprises a telescopic rod piece, the telescopic end of the telescopic rod piece is fixedly connected with a supporting rod, a supporting
assembly is installed on the side wall of the supporting rod, and a fixing
assembly is installed at the end, away from the telescopic rod piece, of the supporting rod. A detection
assembly is installed in the fixing assembly. The first connecting rod and the second connecting rod are matched with the rolling wheel, the supporting rod can be supported in the pipeline, so that a user can conveniently stretch the detection assembly into the pipeline, it is ensured that the detection assembly keeps a stable posture, clear images are obtained, meanwhile, the rolling wheel can be adjusted according to the inner
diameter of the pipeline, and use is convenient. The device can detect pipelines with different inner diameters, the practicability of the device is improved, the detection assembly is fixed by matching a clamping block with a clamping groove, the disassembly and assembly efficiency and the operation convenience are improved, a user can conveniently maintain the detection equipment after disassembly, and the portability of the device is improved.
