Background technology
There are very long coastline and abundant marine resources in China, and there are nearly 3,000,000 Km in the marine site of administering
2(be equivalent to territory, China land 1/3).China will resolve population, resource and environment problem, and an important outlet that reaches medium-developed country at mid-21st Century is moved towards ocean exactly.
Meanwhile, port construction, as traditional coastal engineering category, along with the development of economy and technology, has also run into unprecedented opportunity to develop.At international trade demand and ships that transport, under the trend of large scale development, the scale at harbour, by increasing, requires also more and more higher to fairway depth.And after the limited natural deep sea harbour location exploitation totally of self screening, port construction progressively enters the depth of water marine site that the wave is high.In view of deep water Open Sea environment severe, traditional hydro-structure because construction costs is high, technical sophistication, constructional difficulties etc. can not adapt to deep water port development need.Along with composite demands such as coastal environment protection, sightseeing tour, aquacultures, there is great variation about the idea of seashore and port development in people.In order to adapt to the depth of water, the wave is high, ground weak, introduce exchange of seawater improves water quality environment and cheap demand, and port structure form will be to new structure pattern development such as cancelled structure, energy dissipation type structure and Mobyneb structures.
For the wave of defending off-lying sea to transmit, provide stevedoring operations environment stably, and to protect other port structure things, mole be a kind of common harbour, coastal structures.In contrast to traditional gravity mole, for example upstanding bank and sloping breakwater, floatation type mole has obvious advantage and feature, as: 1) cost is low, and consume material is few; 2) install simply, low to sea-floor relief requirement, be convenient to mobile and dismounting; 3) environmental friendliness is little on seawater and biomass circulating impact.The wooden floatation type mole that Britain built at Plymouth port in 1811 can be regarded as first floatation type mole in the world.During the Second World War, famous Bombardon floatation type mole has been laid by allied forces along 1.6Km place, coastline, Normandy.First floatation type mole of Japan is placed in Aomori port in nineteen thirty, for testing it, resists wave and wave absorption performance.China has built in Danjiangkou Reservoir the floatation type navigation mole that overall length is 134m in 1962.Since the seventies, design success along with the floating breakwater of many dexterities, various floating breakwaters are applied in succession, the floating breakwater structural shape that at present countries in the world put forward mainly can be divided into three kinds of floating box type, float-type and floating raft types, use result for many years shows, this type of mole is safe and reliable.Yet, for current floatation type breakwater structure form, its subject matter facing is: the shielding effect to shortwave (the ratio L/B<4 that wavelength is wide with dike) is fair, but still very high to the transmitance of long wave (L/B>6).
Summary of the invention
Technical problem to be solved by this invention is: overcome above-mentioned existing mole at cost control, long construction period, larger on water circulation impact, and existing floating breakwater is to weak points such as the anti-weave efficiency of long wave are low, a kind of deformable combination type floating shielding is provided, it can adjust adaptively along with the wave height of wave and the size of energy the shape of meeting corrugated, thereby reach better wave dissipation effect, be easy to install and move, have higher reliability, its impact attractive in appearance on water front is less simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A deformable combination type floating shielding, comprises hinged column base, gravity plate, barrier board, anchor chain and high holding power anchor.The whole barrier board that relies on of shielding provides buoyancy, and gravity plate lowers the center of gravity position to improve stability; Whole shielding is that gravity plate and barrier board have been joined together to form to a rectangular box of meeting to incidence wave; It is characterized in that: under the effect of incidence wave, shielding can move thereupon and deform, on it, after plane deformation, formed a breaker face, follow the process of wave aufhellung on breaker face and the collision between wave and works, incidence wave fragmentation dissipates wave energy, plays the effect of wave resistance wave absorption.
Described a kind of deformable combination type floating shielding, is characterized in that: barrier board is divided into two kinds of long barrier board and short barrier boards, all has good water permeability.
Described a kind of deformable combination type floating shielding, is characterized in that: the two ends of gravity plate and barrier board all adopt hinged column base to be connected with other structures.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Embodiment 1:
As shown in Figure 1, gravity plate 1 is fixed on seabed 6 by anchor chain 5; Gravity plate 1 and barrier board (2 and 4) have been joined together to form a rectangular box of meeting to incidence wave; The two ends of gravity plate 1 and barrier board all adopt hinged column base 3 to be connected with other structures.
As shown in Figure 2, barrier board (2 and 4) is comprised of hinged column base 3 and waterproof plate 7, and wherein hinged column base 3 is distributed in the two ends up and down of barrier board.
As shown in Figure 3, wave subduer can be deformed into a parallelogram under the effect of wave.
As shown in Figure 4, wave subduer can be deformed into an irregular polygon under the effect of wave.
The operating principle of the present embodiment:
During actual use, shielding connects high holding power anchor by anchor chain 5 and is fixed on seabed, and device is whole in floating state, and its upper face is a little less than horizontal plane position.When there is no wave action, combination type floating shielding remains static, and its suffered buoyancy and gravity reach an equilibrium state, and the upper plane of wave subduer is lower than sea level, overall structure is all positioned at below horizontal plane, has avoided causing harmful effect to water front is attractive in appearance.When wave is delivered to wave subduer, wave current, partly by the transmission part of barrier board (2 and 4), form turbulent flow, consume part wave energy.Meanwhile, under the effect of wave pressure, rectangular box starts distortion, and it moves and then form breaker face along wave direction of transfer gradually to an extra large side, raises crest height, causes wave breaking to consume wave energy.Shielding can, according to the wave energy size of incidence wave, be adjusted the deformation behaviour of rectangular box upper surface, thereby more effectively reduce transmitted wave wave height adaptively.When wave height is less, wave energy density is when lower, rectangular box distortion is less, from rectangle, becomes parallelogram, forms breaker inclined-plane.When wave height is large, wave energy density is when higher, rectangular box distortion is larger, from rectangle, becomes irregular polygon, forms larger breaker face.
Although above the preferred embodiments of the present invention are described, the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment is only schematically, is not restrictive.
