The utility model relates to a portable pipeline detection device which comprises a first rod body, a movable ring and a movable clamping mark. A measuring mark is arranged on the first rod body in the central axis direction of the first rod body. The bottom end of the first rod body extends into the hoistway to be used for detecting a drainage pipeline in the hoistway, and during detection, after the first rod body extends into the hoistway and is placed at a to-be-detected position, due to the fact that the first rod body is movably sleeved with the movable ring in the central axis direction of the first rod body, the first rod body can be used for detecting the drainage pipeline in the hoistway. The position of the movable clamping mark is adjusted by moving in the direction of the central axis of the first rod body, so that the movable clamping mark is flatly placed on the top face of the hoistway. After the movable clamping mark moves and is adjusted in place, the movable clamping ring is fixed on the fi
