Wave buoy is one of the most comm small monitoring buoys in the field of ocean observation. It is widely used. The study on the structure optimization design and force analysis of small wave buoy is of great significance to improve the overall performance. The previous wave buoy body shape is mostly spherical, the upper cover area is small, the operation space is narrow, the installation and debugging is not convenient, and the number of batteries can be loaded inside is limited. The newly designed cylindrical wave buoy can increase the internal space and the number of batteries that can be installed under the condition that the diameter remains the same. At the same time, it can also increase the opening area of the upper cover, which greatly improves the operating space. The three-dimensional model was established by Inventor 3D modeling software, and then the static analysis was carried out by Ansys software. The results meet the design requirements.
