Floating-type breakwater with anti-rolling function

Abstract

The invention provides a floating-type breakwater with an anti-rolling function. The floating-type breakwater comprises a suspension body suspended on the water surface, a cross beam is fixedly arranged on the suspension body, the part, extending out of the suspension body, of the two ends of the cross beam form cantilevers, floating bodies are hinged to the symmetrical positions of the two ends of the cross beam, and a sliding block which can move along the cross beam is arranged on the cross beam. According to the floating-type breakwater, the structure is novel, the wave elimination and anti-rolling effects are good, the resonance probability of rolling of wave and the suspension body can be greatly decreased, the stress of an anchor chain is lowered, the wind-wave resistance ability ofthe suspension body is improved, both the construction and maintenance are convenient, and the floating-type breakwater can be applied to the production and construction processes in the aspects of coastal ports, marine disaster prevention emergency wave elimination, offshore platforms, marine aquaculture and the like.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, in particular to a floating breakwater with anti-rolling function. Background technique [0002] The floating breakwater is composed of a floating body and an anchoring system. The floating body is composed of a box or a floating row with a certain draft, which is connected to an anchor chain fixed on the seabed at one end and floats on the water. The principle of floating breakwater wave dissipation is based on the distribution characteristics that most of the wave energy is concentrated on the upper layer of the water surface, using floating bodies to reflect, absorb, convert and dissipate wave energy to reduce waves behind the embankment, various types and materials of floating tanks, floating Rafts etc. can be used as floating bodies to prevent waves. In recent years, with the increasing awareness of environmental protection, marine environmental issues have also attracted increas...

AI Technical Summary

Problems solved by technology

[0003] The existing floating breakwaters mainly have the following disadvantages: (1) The wave dissipation effect is not good, which is mainly due to the limited height and width (along the direction of wave propagation) of the floating breakwater structure, which cannot completely block the transmission of waves, especially For long-period waves, the wave penetration rate increases significantly; (2) After the floating body is subjected to the action of waves, it will also move with the waves. The mooring chain is anchored at the bottom of the seabed, and the vertical and horizontal movement is limited to a certain extent, mainly due to the intensification of the rolling motion; the rolling motion of the floating body will not only transmit a certain amount of wave energy, reduce the effect of wave dissipation, but also make the mooring system bear greater force. It affects the safety of the mooring system, so it is of great significance to reduce the roll of the floating body
