The invention relates to the technical field of underground pipeline detection, and discloses an underground pipeline detection device, system and method, and the device comprises a frame body, a sleeve disposed on the frame body, a sliding rod disposed in the sleeve in a penetrating manner, and a detector. The detector is connected to the bottom end of the sliding rod through a steering mechanism, and a controller used for controlling the detector is arranged at the top end of the sleeve. The detector is used for penetrating through a lifting hole of an inspection well cover plate to enter a well to detect pipeline information, the size of the cross section of the detector is smaller than or equal to 30 mm * 17 mm and smaller than the corresponding size of the lifting hole, the detector can penetrate through the lifting hole of the cover plate to enter the inspection well to conduct detection work, and the situation that workers need to open a well cover and go down the well to detect underground pipelines i
