The invention relates to a detection device capable of moving in a pipeline in an
offshore drilling platform pipeline. The detection device comprises a main body, an ejector rod and a rotating frame,wherein the top of the main body is connected with a cleaning motor, the top of the cleaning motor is connected with a
rotating disc, the main body and the cleaning motor are connected through screws,the cleaning motor is connected with the
rotating disc through screws, the ejector rod is arranged at the top of the
rotating disc, the rotating disc is movably connected with the ejector rod, the rotating frame is arranged on the outer side of the rotating disc, the rotating frame is movably connected with the rotating disc, a material guide
pipe is fixed on the inner side of the main body, a cleaning fan is arranged on the inner side of the material guide
pipe, and the cleaning fan and the material guide
pipe are connected through screws. The detection device has the beneficial effects thatthe detection device capable of moving inside the pipeline is arranged on the pipeline of the
offshore drilling platform, a cleaning
brush is arranged, the inner wall of the pipeline can be cleaned,therefore the inner
diameter of the pipeline can be prevented from being reduced due to long-time use of the pipeline, so that the situation that the flow in the pipeline is reduced is avoided.
