Background

With the development of marine observation technology, the demand of on-site buoy observation in (winter) icing sea areas is very urgent, and particularly, the demand is more obvious on observation projects such as sea ice, ocean bottom earthquake and the like.

The compression strength of the sea ice can reach more than 3 times of the bending strength; when the buoy encounters sea ice, the extrusion force between the vertical surface and the end surface of the sea ice can be more than 2 times of the bending force between the oblique conical surface and the end surface of the sea ice, so that the ice resistance of the oblique conical surface of the buoy with the same structural strength can be more than 6 times of the ice resistance of the vertical surface.

At present, when a conventional ocean observation buoy encounters floating ice or ice ridges and the like in a swinging state, the vertical surface of the buoy collides with the end surface of sea ice to generate sea ice extrusion, and the ice resistance is low; when the sea ice with larger thickness is encountered, the buoy is subjected to larger extrusion force, which can cause the problems of the structure damage of the buoy main body, the damage of the anchoring system or the loss of the stability of the floating body, and the like.
