Design and hydrodynamic simulation analysis on debris cleaning robot underwater

Abstract

Abstract In order to clean up the debris in the underwater pipeline or culvert, the structural design and simulation analysis of the underwater dredging robot were carried out. First, the overall structure of the robot was modelled in three dimensions. This robot features a multi-degree-of-freedom moving robotic arm that cleans up any debris in any corner of the culvert under the coordinated operation of the vehicle body. After that, the static analysis of the key parts was carried out, and the dredging robot was hydro dynamically simulated by FULENT software. The drag characteristics of the dredging robot in the culvert environment were calculated by simulation analysis. The results show that the underwater dredging robot meets the requirements for underwater operations in culverts.
