Self-lifting active ice-resistant damping device

Abstract

The invention relates to an automatic lifting, active anti-ice vibration; damping device, comprising upper layer, middle layer and lower layer of annular wing plates, lining boards which are erected between different layers of wing plates and play a supporting role, a hole is established on the middle layer of wing plate; a plurality of anti-ice cables are distributed between the three layers of wing plates, the anti-ice cables pass through the middle layer of wing plate, and are fixed on the upper layer and the lower layer of wing plates; the upper layer of wing plate is connected with the lifting device; a buoy is arranged under the lower layer of wing plate. The automatic lifting, active anti-ice vibration; damping device has the advantages of automatic lifting by adapting the tidal range, eliminating the effect of ice-induced vibration, effectively protecting the ocean engineering structures in winter ice zone.

Description

technical field [0001] The invention relates to an anti-icing device, which is suitable for the protection of pile legs of marine engineering structures in sea areas in ice regions. Background technique [0002] The anti-icing devices of the existing marine engineering structures in the ice area are all cone-shaped bodies installed on the pile legs, and there are upright, inverted or combination of upside down. Some are fixed on the legs, and some can rise and fall with the tide level by means of buoys. Relying on the effect of the cone angle, the ice sheet is transformed from crushing damage to bending damage, achieving the effect of breaking and crushing ice. However, the existing anti-icing devices are all shell structures, and the additional slope increases the contact area between the ice sheet and the structure, and the forward and reverse cone form may also cause ice jamming. In a word, the existing anti-icing devices are all passive protection, and have not played ...

Problems solved by technology

However, the existing anti-icing devices are all shell structures, and the additional slope increases the contact area between the ice sheet and the structure, and the forward and reverse cone form may also cause ice jamming

In short, the existing anti-icing devices are all passive protection, and have not played an absolutely good anti-icing and shock-absorbing effect.
