Buoyancy tank-tire type floating breakwater units and breakwater system with functions of sinking and floating in extreme sea conditions

Abstract

The invention discloses breakwater units and breakwater system which can achieve wave elimination under normal sea conditions and can sink or float in extreme sea conditions. The breakwater system comprises the plurality of breakwater units. Each breakwater unit is composed of a floating body part and an underwater part, wherein the floating body part is composed of a sealing empty box on the upper layer, a ballast water tank on the middle layer and an air bag box on the bottom layer, and the sealing empty box, the ballast water tank and the air bag box are fixedly connected; the ballast watertank on the middle layer is a hollow inclosed cavity, the ballast water tank is provided with a water drain valve and a water inlet valve, and the water drain valve and the water inlet valve are connected to an external buoy I through a connecting pipe; and at least one air bag fills the air bag box on the middle layer, the air bag is provided with an air inlet valve and an air vent valve, the air inlet valve and the air vent valve are connected to an external buoy II through a connecting pipe, the underwater part is composed of rigid supports and suspended tires, and the rigid supports are arranged in parallel. The breakwater units and the breakwater system can not only reasonably avoid extreme sea conditions and reduce the cost of a mooring system, but also meet the requirements of waveresistance and elimination in normal working conditions. The breakwater units and the breakwater system have the characteristics of low cost and environmental friendliness.

Description

technical field [0001] The invention relates to a breakwater unit with sinking and floating functions, and also relates to a breakwater system comprising a plurality of breakwater units, which belongs to the technical field of wave protection of offshore engineering and marine engineering. Background technique [0002] Floating breakwaters are usually wave-proof facilities composed of floating component bodies and mooring systems made of metal, reinforced concrete, rubber and plastic materials. Compared with traditional breakwaters that sit on the bottom, their main advantages are: relatively low cost, High ecological environmental protection, wide adaptability to the environment, etc. [0003] The existing floating breakwaters have poor wave absorption effect under long-period waves, and the floating breakwater structure is difficult to protect itself under severe sea conditions, such as typhoons and other extremely harsh marine environments. In order to ensure the safety ...
