Pipeline micro-leakage internal detection spherical detector is a new type of pipeline leakage detection method. The shape of the pipeline is complex and diverse. Different pipeline shapes have different effects on the movement and force of the spherical detector. Therefore, it is very important to find out the force and movement of the spherical detector in different pipelines. In this paper, the force of the spherical detector, the pressure distribution and the flow field are studied in the pipeline with different inclination angles by numerical simulation. It is found that the flow resistance and drag coefficient of the spherical detector will increase firstly and then decrease, but the lift coefficient will increase with the increasing tilt angle of the pipeline. The resultant moment of the spherical detector subjected to the flow field is relatively stable, and the rolling friction moment increases with the increasing tilt angle. Through this numerical simulation, the force of the spherical detector in different shapes of pipes is obtained, which provides help for the subsequent design of the spherical detector.
