Abstract

The invention provides an anti-ice-piton device and an offshore wind generating set. The anti-ice-piton device comprises a shell connected to a mounting wall and an air bag arranged between the shelland the mounting wall. The anti-ice-piton device enters into an anti-ice state and a shrinking state through inflating and deflating of the air bag. By using the anti-ice-piton device and the offshorewind generating set, an anti-ice structure can be formed under the condition that ice exists, the ice effect load is reduced, shrinking is conducted under the condition that the ice does not exist, and the impact load, acting on a foundation, of waves is reduced.

Description

technical field [0001] The invention relates to an anti-icicle device and an offshore wind power generating set, in particular to an anti-icicle device which can have an anti-icing state and a shrinking state. Background technique [0002] Large-diameter monopile foundations are the most commonly used foundation forms for large-scale offshore wind turbines in offshore areas. However, since sea areas such as the Bohai Sea freeze in winter, structural ice resistance needs to be considered when designing large-diameter monopile foundations. . [0003] At present, the common structural anti-icing design comes from the anti-icing design of jacket platforms in the oil and gas industry, but due to the larger diameter of anti-icing structures on large-diameter monopile foundations Many, it will lead to a significant increase in the wave load acting on the anti-ice cone structure, which in turn will lead to a significant increase in the design load of the large-diameter monopile fou...
