Description
Technical field
The utility model relates to a kind of ramp type wave absorbers.
Background technique
With deepening continuously for ocean development, Wave Theory and experimental study have become major colleges and universities and research institution's emphasis
The field of concern.Experimental apparatus of the wave flume as research wave mechanism, the quality of performance directly affect Wave Theory and grind
Study carefully the reliability of achievement.Due to the limitation of experimental site, the limited length of wave flume, when wave propagation screw clamp closes end
When, end plate can be encountered and reflected.If back wave cannot be effectively eliminated, the flow field around experimental model can be seriously affected.Wave absorption
Device is mounted in wave flume end, to eliminate reflexion of wave, reduces the device of Wave energy, is limited to some places
Laboratory for it is particularly important.
Wave absorber used in wave flume by geometry can be divided into arc surface wave absorber at present, wire netting battle array disappears
Wave apparatus, box wave absorber and ramp type wave absorber.The sink more fixed for the depth of water, arc surface wave absorber have compared with
Good wave dissipation effect.But the arc surface wave absorber optimum depth best there are a wave dissipation effect, once the depth of water in sink
The off-target depth of water, then the device is just unable to reach good wave dissipation effect.The more fixed water of wavelength and wave height for wave
Slot, wire netting battle array wave absorber have preferable wave dissipation effect.But for wire netting battle array wave absorber, air permeability rate along journey not
Change is a defect, this makes wave absorber that can not reach effective wave dissipation effect under the premise of occupied space is lesser, box
Wave absorber is identical as wire netting battle array wave absorber wave absorption principle, also there is wave absorption identical with wire netting battle array wave absorber and lacks
It falls into.
The cardinal principle of ramp type wave absorber is: wave being made to consume portion of energy by way of climbing.This just leads
Cause the gradient of ramp type wave absorber gentler, wave dissipation effect is better, but therefore needs to occupy biggish sink length.
Patent document 2016103521141 discloses a kind of wave absorber being made of multiple partitions being evenly arranged, every
The plane that plate side is constituted is a slope from low to high.Since the wave absorption structure of this kind of wave absorber is single, and only to single
Wavelength has preferable wave dissipation effect, so its wave absorption efficiency is lower.
Patent document 2014104807715 discloses a kind of circular arc type mask wave absorber, mainly utilizes mask portion and dike
Portion collectively forms semi-open wave absorption structure, wave in face of mask portion and on, as gravity influences to fall into the square that mask portion opens up
In shape slot, consumption wave energy is acted on by turbulent fluctuation with dyke.But the wave absorption structure of this wave absorber and wave motion mechanism are not
Match, and equipment is smaller, even if equal proportion expansion can not enhance its wave absorption efficiency.

Accelerate the elimination of remaining wave energy.Flexible membrane both sides are filled with water flow, are also possible to prevent to generate pressure difference, final water flow is from flexibility
The water outlet of film bottom flows out, then is flowed back by the foot passage of wave absorber.
The wave absorber of the utility model carries out compound disappear using a variety of wave absorption modules such as netted wave absorption structure, wave absorption water wheels
Wave eliminates wave energy to the greatest extent, hence it is evident that increase rate wave absorption efficiency；Using the fixed wave absorption module of honeycomb, structure is simple,
There is close robustness simultaneously；Wave successively passes through reticular structure and water wheels, can effectively control the generation of back wave.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel do not need to make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
Within enclosing.
