Efficient floating breakwater based on Helmholtz water wave resonant cavity
The invention belongs to the technical field of design and manufacturing of offshore engineering equipment, and discloses an efficient floating breakwater based on a Helmholtz water wave resonant cavity, which comprises a Helmholtz resonant cavity breakwater main body, a pile foundation and an unpowered lifting limiting auxiliary device. The breakwater body is influenced by tides or waves, buoyancy changes due to sea level height changes, lifting adjustment is achieved through the unpowered lifting limiting auxiliary device, unpowered self-position adjustment is achieved, and the wave absorbing effect of the breakwater is guaranteed. The position of the breakwater body is restrained and limited through the limiting holes and the limiting platforms in the pile foundations. The Helmholtz resonant cavities are utilized, the local resonance type artificial periodic structure formed by periodically arranging the multiple Helmholtz resonant cavities is adopted, the wave absorbing frequency band can be increased, the periodically-arranged breakwater based on the Helmholtz resonance principle is an effective long-wave vibration and wave absorbing mode, the structure is simple, the performance is excellent, the modularization performance is high, and the wave absorbing frequency band can be increased. And when the Helmholtz resonant cavities with the same volume are periodically arranged, the wave absorbing performance is obviously improved.
