Wherein, one end of the first segment 1161 is connected with the power part 14 through the fixing component, the other end of the second segment 1162 is connected with the first segment 1161, the other end of the second segment 1162 is inserted into the power part 14, and the included angle between the first segment 1161 and the second segment 1162 is an obtuse angle. Therefore, the first segment 1161 and the second segment 1162 can form an enclosing structure to enclose the power portion 14, so as to better protect the power portion 14.

Further, as shown in fig. 5, one end of the first segment 1161 away from the second segment 1162 is connected to the bottom surface 112 of the hull portion 11 through the fixing seat 1163, and one end of the second segment 1162 away from the first segment 1161 is connected to the second end surface. Specifically, a mounting hole may be formed on the second end surface, and an end of the second segment 1162 away from the first segment 1161 is engaged with the mounting hole. When the ship hull part is installed, one end of the second section 1162 far away from the first section 1161 is matched with the installation hole, and one end of the first section 1161 far away from the second section 1162 is connected with the bottom surface 112 of the ship hull part 11 through the fixing seat 1163. Thus, the installation strength of the guard bar 116 is ensured, and the assembly difficulty of the unmanned ship 100 is reduced. In this embodiment, the arrangement of the guard bar 116 ensures the navigation safety of the unmanned ship 100, and prevents the unmanned ship 100 from damaging the hull 11 of the unmanned ship when stranded.

To avoid stress concentrations between the first and second segments 1161, 1162, in some embodiments, the first and second segments 1161, 1162 are rounded. Thereby increasing the structural strength of the guard bar 116. As shown in fig. 1 and 2, in some embodiments, the guard bar 116 is multiple, and multiple guard bars 116 are arranged in parallel. This can protect the power unit 14 more effectively. Furthermore, as shown in fig. 3 and 4, at least two guard bars 116 are provided on each power unit 14.
