Float-type breakwater

Abstract

The invention provides a float-type breakwater. According to the float-type breakwater, diversity of wave absorbing methods is achieved through a first anti-wave unit, a second anti-wave unit and a wave absorbing plate; the first anti-wave unit blocks wave crests, thus wave is effectively reflected, when the wave is too high and crosses the tip of a head wave plate, the wave is turned up and fallson the head wave plate and a back wave plate, the wave is crushed, thus wave energy is cut down, the impact force of the wave on a buoyancy tank is reduced, and the stability of the buoyancy tank isimproved; through the combined action of the wave absorbing plate and the second anti-wave unit, the wave absorbing effect is further improved, and the transmission coefficient of the wave is reduced;by using an air cylinder, an upper telescopic assembly and a lower telescopic assembly, the length of the second anti-wave unit can be changed to adapt different wave conditions, and flexibility andmaneuverability are greatly improved; the wave spreads and transmits by using the wave absorbing plate after passing hole-shaped crushing, wave energy attenuation and wave crushing, the wave energy issequentially cut down through the wave absorbing plate and the second anti-wave unit, and thus it is guaranteed that oscillatory waves under the water is cut down as quick as possible, and calmness is restored as quick as possible.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a floating breakwater. Background technique [0002] The breakwater is a water structure built to block the impact of waves, maintain the harbor basin, maintain a stable water surface to protect the port from bad weather, and allow ships to berth and operate safely. The breakwater is located on the periphery of the port waters, and prevents the invasion of drifting sand and ice, ensuring sufficient water depth and stable water surface in the port to meet the requirements of ships berthing, loading and unloading, and entering and leaving the port. [0003] Floating breakwaters are one of the types of breakwaters. Floating breakwaters are composed of wave-dissipating floating bodies and mooring equipment. The principle of wave-dissipating is to use floating bodies to organize wave ships or break waves, and to float up and down and swing back and forth under the action of...

Problems solved by technology

[0004] According to wave theory research and experiments, the energy of waves is concentrated on the surface of the water body, and 98% of the total wave energy is concentrated in the depth range of three times the wave height below the water surface. However, in the face of long-period waves, the existing floating breakwater The wave penetration rate is high, the wave dissipation effect is not obvious, and the wave dissipation method is single. Generally, only the principle of wave reflection is used to simply eliminate waves once, and it cannot adapt to different wave height states.
