Description

In areas where sea ice is serious, the sea ice load is designed control load of the offshore fixed photovoltaic power generation platform structure, and stability of the platform structure can be greatly affected.

In order to reduce the ice load on the ocean platform, the current common measure in the engineering field is to add ice cones on the tubular pile struts of the platform structure, so as to reduce the maximum ice load of sea ice on the platform structure and ensure the stability of the platform structure. The existing ice cone body is generally composed of a simple cone structure, and comprises an upper cone body and a lower cone body which are installed up and down symmetrically, and sea ice acts on the ice cone body to form radial and annular cracks, so that a sea ice plate is bent and damaged. Compared with extrusion damage caused by direct impact of sea ice plates on the pipe piles, the bending damage has much smaller acting force on the platform structure.

After the sea ice plate is bent, damaged and broken, broken sea ice can climb along the inclined plane of the ice cone under the action of a surge, at the moment, the sea ice climbing onto the ice cone can generate extrusion static ice force on the pipe pile support column through the ice cone, and the extrusion static ice force is concentrated to act on a specific area of the pipe pile support column due to the fact that a conical surface generatrix of the ice cone is a straight line, the pipe pile support column is stressed and concentrated, and the service life of the pipe pile is reduced. Meanwhile, as the generatrix of the ice cone is a straight line, broken sea ice is easy to attach and accumulate on the cone surface under the action of a surge, and broken sea ice is not easy to crack secondarily, the sea ice attached on the cone surface is inconvenient to clear and unload, the pipe pile support and the ice cone are loaded for a long time, and the service life of the pipe pile is also reduced.

Therefore, designing an anti-icing device that can avoid stress concentration of the tubular pile pillars and avoid sea ice accumulation is a technical problem to be solved by those skilled in the art.
