Expandable floating breakwater

Abstract

The invention discloses an expandable floating breakwater, including a hollow buoyancy tank, expandable plate boxes, vertical wave absorbing plates and a mooring system. The hollow buoyancy tank is vertically arranged, and the front end and the rear end of the hollow buoyancy tank are correspondingly provided with the expandable plate boxes, the two expandable plate boxes stretch and contract in the front end and the rear end of the hollow buoyancy tank direction, and expandable locking mechanisms are arranged on each expandable plate box which penetrates through a plurality of vertical wave absorbing plates, by adjusting the expansion of the expandable plate boxes, the distance of the vertical wave absorbing plates is adjusted, vertical heaving plates are correspondingly arranged on outmost vertical wave absorbing plates at the left end and the right end of the hollow buoyancy tank, airbag systems are mounted above the heaving plates, and the mooring system is arranged below the heaving plates. The expandable floating breakwater has the advantages that the wave absorbing performance is good, the water area application is wide, transportation is convenient, and the layout and disassembly are quick and convenient.

Description

technical field [0001] The invention belongs to the breakwater technology, in particular to a retractable floating breakwater. Background technique [0002] Floating breakwater is a wave prevention and wave dissipation facility that floats on the water surface constrained by the mooring system. Compared with the bottom-seat breakwater, its construction, installation, and disassembly are faster, reusable, and not affected by underwater conditions, and the layout area is wide. In the near shore, the floating breakwater shelters relatively stable waters for port engineering, ship mooring, aquaculture, and offshore water sports, ensuring smooth water circulation in the shelter area and reducing sediment deposition. In the far sea, in response to the country's call for "marine power, to the deep blue", deep sea engineering has developed rapidly. According to the theory and experiment of water waves, 98% of the wave energy is gathered from the surface of the water body to 3 time...

AI Technical Summary

Problems solved by technology

[0003] At present, floating breakwaters can better eliminate waves with a period of 5s. However, in the open sea where the sea conditions are more severe, the wave periods are distributed in the medium and long periods of 6-10s. The near-shore floating breakwaters cannot meet the requirements of deep sea engineering.

And if only the width of the breakwater is simply increased, the economy will be reduced, and it is not easy to realize in the project

[0004] At present, there are few floating breakwaters that can absorb medium and long-period waves, and in order to increase the dike width and enhance the wave-absorbing performance for medium and long-period waves, most of them connect the front and rear buoyant units through connectors. The installation and disassembly of type breakwaters are cumbersome, and the construction intensity is high
