Description
Technical field
Single anchor leg formula of cage buoyancy compartment encloses Hai Zhu, is a kind of new technology new equipment for enclosing sea cultivation exclusively for solution, together
When be also to solve to enclose the new technology new equipment of extra large three-dimensional culture large cage, be exactly three-dimensional culture big net in marine formed a circle with it
Case, the invention belongs to ocean engineering fields.
Background technology
It encloses a kind of form that sea cultivation is sea-farming enlargement and low-density may be implemented since culture in enclosure water body is huge
Ecological environmental-protection cultivation mode, since cultivation fish has enough activity spaces, fish products matter approximation is wild, is high-end marketable fish.Due to
Low-density cultivation meets the objective law of " existence capacity ", thus has thoroughly prevented the generation of breeding pollution.
Big volume, low-density cage culture have become common recognition, and military ship is 4.2 hundred million RMB of cost that Norway builds, and 110m is straight
Diameter large cage, the 125m diameter large cages that East Sea aquatic products research institute builds in the case where World Copper association supports, illustrates this trend.
Northern Europe cage culture comment (FAO) has also spoken of this development and has become Potential：It the article pointed out the development example using larger unit, perimeter
Increase 157m and 30m from 40m and 4m respectively with depth, volume is respectively 510m3And 59000m3。
But it is backward in technique to enclose extra large cultivation project at present, encloses sea using pile-column, investment is big long in time limit, is also fallen using original
After build Dam modes and enclose sea, welding is gone back in not only gigantic project.This explanation encloses extra large cultivation project technology at present, much adapts to not
Enclose the needs of sea cultivation development." single anchor leg formula " buoyancy column of offshore oil, removes complicated and expensive operation cost of driving piles from, related
Concept referring to referenced patent document [1] " deep water anchor strut " patent No.：ZL2013 2 0616701.9.
The utility model according to offshore oil " single anchor leg formula " buoyancy column and referenced patent document [1] " deep water anchor strut "
The patent No.：2 0616701.9 illustrated principles of ZL2013, are creatively used in and enclose extra large cultivation, especially its construction cost and
Make big innovation in safety, cost will be greatly lowered and simplify Attention problems engineering, the application of the technology is to enclosing extra large cultivation
It will be of great importance.
It to point out in passing：It is formed a circle marine with enclosing Hai Zhu, is exactly three-dimensional culture large cage, therefore, this technology
It is to make safety, the new technology new equipment of economic, applicable large size or ultra-large type three-dimensional culture large cage.
Using " single anchor leg formula " configuration aspects, offshore oil has considerable theory and experience, is stored up in mooring Floating Production
Oil tanker (abbreviation FPSO) collects store oil, processing, outer defeated marine giant (the small then a few kiloton of ship tonnage, greatly then more than ten being integrated
Ten thousand tons) when, this technology, wherein two point mooring most reference value are just used, this is a kind of substantially ancients " with soft gram
Just " the technology of philosophic theory, avoids " very stiff and demanding ", and powerful effective elasticity cushioning effect both reduces basic stress, also slows down to floating
The impact of body.CNOOC Zeng Hengyi, Wu Si etc. most early in " two-point mooring gear " patent No. ZL95205025.0, describes
Applied to the float-type anchoring system of floating production storage unit, a large amount of engineering examples, and indoor basin test number are listed
According to having made outstanding contribution for the application of this technology.
The technical principle is：On the basis of the floating drum of huge buoyancy has been fixed on enough withdrawal resistances by cable, floating body such as ship
Oceangoing ship, the mooring of floating platform etc. is on floating drum, it is assumed that wind, unrestrained, the mooring force generated under flowing common action make floating body generate inclined
From corresponding tilting complex torque is that clockwise, buoyancy then generates anticlockwise righting moment, and the two is just reversed, i.e.,
Buoyancy meeting acting in opposition makes it return to equalization point, and to realize dynamic equilibrium, here it is the principles of compliant type balance (referring to figure
11).This principle is widely successfully applied to engineering practice in marine petroleum development, it is typical such as single point mooring, tension leg
Formula platform etc., listed several inventions in referenced patent document, equally applies this principle.
If with the experience that ocean engineering is developed, using the two point mooring theory of floating production storage unit (abbreviation FPSO) as base
Plinth is transformed equipment itself, it is made to walk out offshore oil high-tech, the circle of high investment, realize functionization, privatization,
The target of universalness, wherein the patented technology detached with stressed member using our buoyancy pieces, rather than conventional compartment way, greatly
The buoyancy compartment cost to play a decisive role to cost is reduced to amplitude, undoubtedly these improvement are great meanings.
