In the cold season, pipelines are prone to icing-induced clogging, causing great inconvenience to people’s production and life. To solve the icing-induced clogging of the pipeline, analysis was made on the reason why the original device fails to break the ice, to provide some guidance for conducting an innovative design of the cutter head of the device. Based on the actual needs for the cutter heads in the course of ice-breaking, a parallel inclined spherical rotary cutter head was proposed, and its 3D model created with the help of a modelling software. Through the operational and arc-traversing performance analyses of the cutter head, the relationship between the radial direction and the axial direction of the cutter head was constructed. The pressure relationship of the device was analysed. The conclusion was drawn as follows: the designed cutter head can improve the effectiveness of the device on ice-breaking and reduce the requirement for the structural intensity, providing a significant basis for the development of its physical prototype.
