Description
Technical field
This patent, from technical standpoint, is related to the integrated application to ship and ocean engineering technology, belongs to ship and ocean work
Journey equips class technical field.This patent is mainly used in aquaculture, therefore may belong to marine aquaculture tool-class technology neck
Domain.
Background technology
With China's expanding economy, people get more and more to the demand of aquatic products, the also more and more higher of the requirement to quality.
Salvage native species using fishing boat to rivers,lakes and seas and far can not meet the market demand.Now many inland rivers of China, inland sea,
Near coastal, coastal waters the bay in continent, the preferable waters of every condition, all by the aquaculture net cage institute at numerous fishery cultivating families
Cover.For cost-effective, the net cage that fishery cultivating family uses now, be mostly small-sized net cage, its material mostly be plastics, foam,
Timber etc..Do not possess the resist ability to off-lying sea relatively strong winds wave.
At present, large area carries out the industry of aquaculture using inland river, inland sea and bay and technology suffers from the drawback that：
(1) exploitation of excessive aquiculture net cage, occupies water surface area limited in a large number, with coastal industry, real estate
The exploitation of the industries such as industry, tourist industry creates the contradiction in contention waters, excites numerous social event.
(2) inland river, inland sea high-density aquiculture also result in the pollution of water field of big area, and cause all kinds of aquatic products product
The degeneration of matter.
Therefore, support it is necessary to realize Aquatic product for fundamentally solving the problems, such as that aquaculture occupies large area inland sea, inland waters
The off-lying sea grown.
Aquaculture off-lying sea, it is possible to use the inexhaustible plankton in off-lying sea, as bait, is greatly lowered cultivation
Cost；The delicious aquatic products of high-quality can be obtained；Additionally, off-lying sea has stronger self-purification function, aquaculture can be solved dirty
The problem in dye waters.Aquaculture off-lying sea, has become the developing direction of culture fishery.
The difficulty realizing aquaculture off-lying sea in technical elements essentially consists in：
(1) safety problem of aquaculture
China coast (especially southeastern coast), is the waters of typhoon more than.Aquaculture off-lying seaization must solve outer
Caulis Piperis Kadsurae wave is huge, causes that poultry feeders operation is dangerous, the easily destroyed problem of net cage.
(2) problem with high costs
Once it has been proposed that, the outer saline waters in the close continent of aquaculture will be suitable for, fenced up with breakwater, artificial create
Make a piece of quiet bay.This idea is unpractical.Its reason is：If building fixed breakwater, not only become
This is extremely high, and can separate Cultivated water with the external world, causes sea water can not flow freely, and becomes and encloses sea and breed fish, even if
Off-lying sea is become inland sea, also have more than is needed how long, can be formed again and be covered by net cage similar to the limited waters in fishing ground now
Situation；If building floating type breakwater, not only net cage cost is still high, and especially big stormy waves (attacking as big typhoon)
Under the conditions of, the effectiveness of the actual wind wave prevention of its floating breakwater will be had a greatly reduced quality, and breakwater yet suffer from itself very big
Security risk.
Therefore, the fundamental solution realizing aquaculture off-lying sea is to create a kind of aquiculture net cage of energy wind and wave resistance.
Utility model content
The purpose of this patent is to resist the stormy waves of off-lying sea for the used net cage of existing inland sea cultivation, and therewith
The supporting floating breakwater problem that actual effect is not good in especially big typhoon and security risk is very big and propose, with ring-type hinge
Connect the off-lying sea aquaculture technology that formula net cage is core technology.
The basic ideas of the art of this patent scheme：
Take into account the contradiction of ship performance and intensity：
General knowledge teaches that, the canoe in a park is it is impossible to go to sea to navigate by water, but big ship is just permissible.Its reason is big
The stability of ship is good.But moment of flexure is again very big for big ship always indulging on wave, and structure easily goes to pot.If ship is done circlewise, no
Only its construction cost can be greatly lowered, but also larger moment of inertia of waterplane can be obtained it is possible to obtain larger just
Metacentric height；If longer ship is divided into several sections, being hinged together, being not only difficult to turn over and sink but also can make structural strength to be ensured,
This can take into account the contradiction of performance and intensity.The ultimate principle of " ring-type radial type net cage " that this patent proposes is based on this.
With regard to off-lying sea design maximum wind scale：
The net cage that this patent proposes, has very strong capacity of anti-storm it is not necessary to using breakwater it is adaptable to except polar region
Unlimited sea area beyond (near south poles), is particularly suited for the Fields In Chinese Continental Shelf shallow sea water of the depth of water 30～100m.
One of the feature in coastal area of china waters is：The diastrous weathers such as typhoon occur more frequent.For example in ALONG COASTAL FUJIAN
The Luoyuan in portion, Liaanjiang county one carry, and according to the data of inshore observation station (1985-2012), all can tropical storm or big every year
Typhoon.In normal weather, its seashore annual mean wind speed only in 3.1m/s, but when the diastrous weather such as big typhoon occurs, 10
Minute maximum wind velocity, just up to 46.7m/s, is equivalent to 15 grades of Beaufort scale, the harm causing is extremely serious.Thus, this patent
The design wind scale that net cage is suitable for now is set to 16 grades of Pu Fu, and that is, the wind speed away from sea 10m height is 53.5m/s.Be equivalent to century-old one
Meet.This patent net cage must have enough stabilities and structural strength under the effect of design maximum wind-force.
With regard to stability and structure：
From the point of view of design with computational methods, " ring-type net cage " that this patent proposes, the ship that actually a kind of centre hollows out
Oceangoing ship, complies fully with the feature of ship defined in classification society rule.Thus, about Ship Design and the ripe theoretical and side building
Method, specification and regulation etc. all can be applied mechanically, and have very strong practicality.Even if so, in design, still have to strict ship
Mould is verified.
The method commonly used by Marine engineering, through preliminary Performance Calculation, may certify that " ring-type net cage " that this patent proposes is steady
Property is fine.Its reason is：This net cage, moment of inertia of waterplane is big, center of gravity is low, and wind area is less, though wind-force is very big, still
Will not topple.Through the conclusion that preliminary structure calculates it is：Because this net cage is using hinged, short cable will be used by each part (" unit ")
Couple together with bitt (being commonly called as " checking bollard "), thus its always indulge moment of flexure, shear force will greatly reduce it can be ensured that net cage body construction
Safety.What bearing load was maximum is bitt and short cable and its structural reinforcement member, belongs to local strengthening category.And short cable connector
It is the conventional mooring arrangement of ship, can apply mechanically by the mode standard of ship specification.As long as taking certain safety coefficient it is possible to really
Protect attachment security.
The theory and practice of Structual Mechamics for Ships is all proved：For being opposite to the ship on wave, if wavelength X is remote
Less than captain L, i.e. λ/L<<1, then have several crests in the range of captain L and occur with trough, its wave height H1/3It is less,
Buoyancy with respect to hydrostatic state change less, will not produce larger wave additional bending moment；If conversely, wavelength X is much larger than captain
L, i.e. λ/L>>1 although wave height is very big, but in the range of captain L, corrugated is also more or less the same with standing level it is also not possible to occur relatively
Big wave additional bending moment.It is directed to 16 grades of especially big violent typhoon, using the articulated manner of this patent, by net cage maximum module
Characteristic length L diminishes, i.e. λ/L>>1, therefore the additional wave moment producing is also less (referring to the example calculation of this patent).
A kind of off-lying sea cultivates the composition of wind resistance wave type radial type net cage：
Off-lying sea cultivation base：
So-called " off-lying sea " of this patent indication, generally refers to the marine site away from continent.It is engaged in culture fishery in off-lying sea, need
Oneself to solve the problems such as such as supply, bait, breeding, the life of management personnel and working condition, plant maintenance.Typically should adopt
With intensive way to manage, net cage should be combined into a colony, form base.This base typically should be located at the natural shoal of fish

Formula.It was verified that this kind of mode is simple and safe and reliable, there is the effect relaxing wave stroke, reducing the damaged probability of structure.
Below according to Principles of Ship Designing, provide the design example of the radial type net cage module of an a diameter of 200m, say
Bright specific embodiment：
Design considerationss：
Net cage uses sea area：
This net cage is applied to " off-lying sea " in Liaanjiang county Xiamen, the Taiwan Straits Fujian, and position is about eastern 118 ° -120 ° of footpath, north
(calculated examples are taken as 25 ° of N, earth rotation Corrioli's effect coefficient to 23 ° -26.5 ° of latitude：F=0.22 vast marine site), this marine site is platform
Gulf both sides of the Straits multiple stage edema due to wind pathogen domain.
Design wind scale：
Especially big typhoon (10m wind speed, the U on sea of 16 grades of Beaufort scaler max=53.5m/s).
Certain weather station is as follows to the determination data of once especially big typhoon：
Local Zenith Distance presses Pa=1013.6 hundred handkerchiefs (hPa)
Center of typhoon blast：Po=914 hundred handkerchiefs
Draught head：Δ P=Pa-Po=99.6 hundred handkerchiefs
Maximum wind speed radius (away from the distance of center of typhoon)：R=27 nautical mile=50 kilometers
Typhoon Tracks speed：Uf=20 sections=37.0km/h=13.37m/s
Typhoon region element of wave calculates：
Element of wave referred herein refers to wave height H1/3, wavelength X, cycle T1/3.
Using more general Bretschneider (1957) following empirical formula
When calculating 16 grades of typhoons, the maximum of element of wave is as follows：
Greatest gradient wind speed (U at 10m on seag)maxFor：
(Ug)max=0.868 × [73 × 0.1718 × (Δ P)1/2-0.575R×0.22]
=105.23 (saving)=54.14m/s
Maximum sustained wind speed U at 10m on sear(saving), is drawn by following formula：
For mobile typhoon：
Ur rmax=0.865 × (Ug)max+0.5Uf=104.02 sections=53.52m/s
This value is equivalent to 16 grades of Beaufort scale, tries to achieve Ur rmaxAfterwards, following two formulas of recycling can be in the hope of this typhoon formation
Deep water maximum significant wave height H1/3maxAnd cycle T1/3max.
H1/3max=5.03exp (0.000295 × R × Δ P) × (1+0.208 × Uf/(Ur)^(1/2))
=17.02m
T1/3max=8.6exp (0.000148 × R × Δ P) × (1+0.104*Uf/(Ur)^(1/2))
=16.2s
Cycle according to deep water wave with calculate wavelength relation table, can check in corresponding to this wave period wavelength such as
Under：
λmax=545.5m
After typhoon formation, it is referred to as typhoon eye in the range of center of typhoon 10km, almost calm.Apart from center of typhoon about
In the range of 40-50km, wind speed is directly proportional to r increase, and this scope is referred to as typhoon internal area.Away from the outer rim of center of typhoon 40-50km, past
Toward the maximum U that wind speed occursr max, referred to as maximum wind speed radius R (this example is 50km)；Outside here distance, until radius
500km, referred to as foreign lands area, wind speed is generally reduced in the ratio of 1/r^ (1/2)；Increase again apart from r, to 800km, can be considered platform
Outside solar or lunar halo, ratio is reduced by wind speed in 2/r.
The wind-induced wave of marine platform also has an Emergence and Development, stable, to the process gradually weakening, disappearing.Here mistake
Cheng Zhong, the composition ripple in various wavelength, wave height and cycle is all possible to be occurred.For ship (inclusion net cage), structure is produced
What destructive power was maximum is not wavelength wave the longest or shorter, but the ratio of wavelength and captain is close to 1.0 composition ripple.Cause
And, when calculating net cage stability, should consider by maximum wind velocity；And in computation structure stress, should be by wavelength X and net cage unit
The ratio ≈ 1.0 of characteristic length L considers.
Choose 3 net cage characteristic lengths, calculate its element of wave：
First, rounding net cage (diameter) captain, L1=200m；
Second, taking ring element in net cage central island 1+, its diameter L2=120m；
Third, taking net cage outer shroud element length L3=75m；
Examination calculates the element of wave of its wave load maximum case：
Through the author's regression analyses, draw routinely wind velocity UrWith unrestrained high H1/3Relation such as following formula：
H1/3=0.08 × Ur 1.55
Apply mechanically the wind speed of other researcheres proposition and the regression formula of wind scale again：
Ur=0.836 × B1.5
Can obtain：H1/3=0.08 × (0.836 × B1.5)1.55=0.0606 × B2.325
In typhoon internal area it is assumed that wave height H1/3, cycle T1/3Generally also reduce in the ratio of 1/r^ (1/2), thus also may be used
To deduce wave height H during its wavelength1/3, cycle T1/3As following table：
(referring to subordinate list 2)
Specified sea areas typhoon zone storm wave element computational chart
Subordinate list 2：The calculating of specified sea areas typhoon (referring to《Wave projectional technique in coastal engineering》One book)
Overall structure and the comparison of articulated structure stressing conditions：
The empirical equation providing by typhoon scholars, be can be seen that by above rough calculation：In a typhoon formation simultaneously
After stable, maximum to the structural strength harm of ocean engineering structure is not in the maximum region of wind speed, because now
Maximum wavelength λmaxOften it is much larger than characteristic length L of works.But move away works certain distance in center of typhoon
When (at the r=102km of this example), it is exactly in λ1=L1(L in this example1=net cage diameter D) situation, wave height now
H1/3Higher, reach 11.91m, this example net cage frame moldeed depth is only 6.5m, if it is H that overall structure center is placed in wave height1/3=
11.91m, wavelength be 200m trochoidal waves on when, additional wave bending moment be than larger (thus example explanation, if it is normal to press ship
Rule computational methods, take wave height to be 1/20 captain, that is, take calculating wave height to be 10m, are relatively dangerous)；But if structure is cut with scissors
Pick up, the wavelength of precarious position and wave height all can reduce, for example, take λ3=75m, now, wave height H1/3=7.46m,
Then the structural strength of ship will be much more secure.Add by the wave of ship and always indulge square being directly proportional of moment of flexure and captain, wave
The rule that additional shear force is directly proportional to captain, if with net cage generally 100%, the main body that " central island+internal ring " forms is with outward
Ring element is hinged, and central island hinged with internal ring after hinged with outer ring element again, the wave of three kinds of situations adds always indulges moment of flexure
Ratio is：100%th, 36%, 14.64%；Its wave additional shear force ratio is：100%, 60%, 38.27%.Illustrate that difference is very big
's.(referring to subordinate list 3)
Subordinate list 3：The net cage unit wave of different scale combination always indulges the proportionate relationship of moment of flexure and wave shear force
It is computed, the actual calculation of this patent is as shown in appendix 1.
