Description

Based on the environmental and ecological net cage of the dual-purpose of the water surface under water wind wave resistance of articulated platform principle

Technical field

Based on the environmental and ecological net cage of the dual-purpose of the water surface under water wind wave resistance of articulated platform principle, be a kind of novel net cage solving deep water waters underwater culture, outstanding wind wave resistance and environmental and ecological feature, belong to ocean engineering field.

Background technology

Cage culture is the pith of marine economy, the net cage that the polyvinyl piping materials (being called for short HDPE) introduced by Norway at present makes is in full flourish, in the yellow Bohai Sea, the East Sea, the South Sea, all in a large amount of use, this with the floating of HDPE material making or floating type net cage, although floating type net cage has sink-float function, before typhoon, can certain depth be sunken to, evade the wave stroke that the water surface is maximum, but still have following fatal defect from this net cage of practice:

1. be not suitable with the impact of ocean current, just may deform when current speed only reaches 0.257m/s according to observations, when flow velocity reaches lm/s, body is held in loss 80% cage culture, be limited by ocean current like this, just lose the better culture resources of a large amount of water quality give-and-take conditions.

2. because this kind of net cage of above-mentioned reason can only use at right up and down inner bay, because raiser swarms in this narrow and small inner bay, cause water quality in gulf very severe, even stinking smell assaulting one's nostrils, fish poor quality, fish disease is many, a most valuable line seascape is lost in coastal city, this just forces local government in order to city development, have to go by force to drive inner bay, offshore cage culture family, as Guangdong is being cleared up from west to Dongdu, toll breakdown inner bay, offshore fish culture net cage, but the technical support used because not having open waters, this can catch Wu Fish with regard to making the fisherman in these past be in, again without the very difficult condition of Hai Kegeng.

3.HDPE net cage plane stiffness is poor, bent flat i.e. unstability is one of principal mode of its destruction, in August, 2013 typhoon " especially " blow Yangjiang, Guangdong and Raoping, local net cage is caused to be annihilated, this is in the better situation of net cage anchoring mooring, present unstable failure under the rotation action of ocean current that Net-cage frame causes at typhoon, its damage-form is as casing " turn round fried dough twist ".Certain net cage anchoring and mooring problem do not solve always, so that floating or floating type net cage under typhoon, not possibility wind resistance, in by the end of September, 2011 Lingao, Hainan at the fish culture net cage of open waters, at typhoon " Ni Ge " attack under be annihilated, half is blown loses to off-lying sea, and half blows to bank and batters down, the fish one of fast results is not all got back, only the economic loss of three companies nearby 800,000,000.Same disaster also occurs in September, 2013 Zhangzhou, Fujian, typhoon " Jade Hare " cause damage several hundred million unit, in July, 2014 occurs in the typhoon of Hainan and west of Guangdong Province Yuexi, Guangdong " Amazon ", countless raiser be can't regain one's original capital, although, Hainan raiser has drawn typhoon in 2011 before this " Ni Ge " lesson that attacks, do improvement by the Oceanic and Fisheries Room 2011, Hainan Province dispatch in the end of the year " the guiding suggestion about resuming production after deep-water net cage culture calamity ".

Due to the backwardness of net cage technique, deep water mesh cage development is cold by heat, the industrial zone of state plan, not only do not increase, have on the contrary and subtract, within 2014, unexpectedly occur the phenomenon (as ancient cooking vessel in Yangjiang) that large cultivation company quits listing, according to another saying that Guangdong empty van rate is up to 60%, some are contracted already and march deep water mesh cage enterprise, because using without reliable net cage, slowly do not have action.

From the cage culture of analysis development open waters, need the limitation breaking through HDPE net cage, seek a kind of safety, reliably, Anti-Typhoon, be applicable to ocean current comparatively urgency and the novel net cage without the open sea area of shield, the development of deep water mesh cage cause is got up.According to domestic and international existing experience and theory analysis, the net cage improved route first element should be replace current HDPE structure by flexible structure, and avoid unstable failure, it is good that the second cage structure should choose hydrodynamic performances, the version that capacity of anti-storm is strong.The floating platform of offshore oil series is as semi-submersible type, tension leg type, barrel mast formula (English SPAR), articulated (English ARTICULATED COLUMNS) is exactly desirable version, play a great role in the nearly halfth century alive boundary marine petroleum development of the type structure, particularly contribute larger in the oil development of deep-sea stone, the type structure has following features:

A. structure centre of buoyancy is upper, center of gravity under, there is permanent stability and unconditionally balance.

B. structure buoyancy is much larger than dead-weight balanced buoyancy, as shown in figure 23, the buoyancy compartment of enough large buoyancy couples together with the ballast tank being positioned at the enough large ballast of column bottom, after the two is in poised state, therebetween just tension force is created, assuming that wind, wave, the horizontal force produced under flowing common action, it makes buoyancy aid generation depart from, if horizontal force produces the tilting complex torque of up time Needles, buoyancy then produces inverse time Needles righting moment, and the two is just in time reverse, and namely buoyancy can make it get back to equalization point by acting in opposition, thus realize dynamic equilibrium, the principle of compliant type anchoring that Here it is.Wherein articulated platform as shown in figure 22: the universal hinge 21 being stood on base surface 23 by seat is connected to column 18, a buoyancy compartment 19 is had to provide buoyancy above column, under have a ballast tank 20 to provide ballast, it is made to be in poised state, therefore column has just had upright self-buoyancy, when constant level, basis need not carry resistance to plucking or tension, the withdrawal resistance that SEA LEVEL VARIATION causes is limited (when buoyancy compartment is designed to be in lowest astronomical tide+maximum storm tide during lowest water level under most billow paddy, therefore only having buoyancy increment) then.

Application ocean engineering is ripe, reliably, the technology of extensive successful Application, four articulated platform rod members or cable up and down are formed box-shaped by imagination, then hanging up etting, is not exactly a safety, reliably, Anti-Typhoon, anti-ocean current novel net cage? the present utility model just develops according to such thinking.

By the experience of the present utility model people according to offshore oil long-term work, research and development and oneself obtains the patent of being authorized " deep water anchor strut " patent No.: ZL2013 2 0616701.9 and " air bag regulates buoyancy can with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " patent No. ZL201320623481.2 applies offshore oil floating platform design feature the earliest, i.e. post stability---adopt and regulate the large cylinder of buoyancy to make supporting structure, connecting cable up and down to form, is typical flexible structure.By the present utility model, people researches and develops, oneself obtains another patent of being authorized " can with the tension leg type deep water mesh cage of fluctuation in stage heave " patent No. 201320095246.2 first proposed the scheme that damping prevents swinging plate in the world, this ecological, environmental protective for breeding water body is extremely significant, because, the ight soil of cultivation fish and residual bait drop on damping to be prevented swinging on plate, mud face can not be fallen into and roll up pollution source, but be converted into other fish and species nutrient, also can reduce net cage mountain peak ripple simultaneously, reduce net cage breakage risk.

The problem that the special Needles of the utility model proposes deep water waters underwater culture, this is based on considering below:

1. in general live in the fish of bottom, be mostly the kind that matter good price is high, economic worth is large, as grouper, therefore, needs the net cage that underwater culture is suitable for.

2. as the ratio d/ λ > 0.5 of the depth of water with wavelength, when being deep water waters, water body particle follows circular motion, radius of circle is exponentially decayed downwards from the water surface, and be about 1/5 of the water surface in the horizontal velocity component of half depth of water place water particle, net cage only affects by underflow under this degree of depth in theory, so, net cage being placed in sea bed is safest measure, and a step of sinking walked out by floating type HDPE net cage, but can not accomplish to be placed in this step of sea bed face because constructing reason.

Therefore; the utility model be to " can with the tension leg type deep water mesh cage of fluctuation in stage heave " patent No. 201320095246.2 and " air bag regulates buoyancy can with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " patent No. 201320623481.2 beneficial complement; for raiser provides a dual-purpose of the water surface under water novel net cage; its outstanding wind wave resistance and ecological, environmental protective advantage; become and march deep-sea; benefit fisherman, the reliable equipment of protection of the environment.

Embodiment

As Fig. 1, waterborne shown in 2, underwater net cage is the same, and sole difference is that the modular converter assembly carrying function adjusted by band, can save railing, so its embodiment can be set forth together to underwater net cage.

The making of net cage due to main body total flooding under water, and it is different from the buoyancy post series of patents of authorizing, structure heave can't help four corner posts control, therefore, steel or its small volume of composite column obturator, structure is comparatively simple, and the tubular shell made of steel can first filling polyvinyl chloride or polyurethane foaming body 101, also after can making closed cylindrical shell, perforate is filled, last cap holes.The own rod member 5 closed of same bar two end, rod member 6, for insurance also requires filling polyvinyl chloride or polyurethane foaming body 101, because steel or composite column obturator 1 are as permanent buoyant tank, reliable buoyancy should be had, although be filled with polyvinyl chloride or polyurethane foaming body 101, still require that cylindrical shell has reliable seal, after making, should leak check be made.

Whole net cage makes and there is no difficult point, and explanation done again by drawing, as long as conscientious construction in line with the drawings makes, but should pay close attention to following points:

1. the making of hanger class: comprise hanger assembly 2, free suspending weight bar hanger 402, buoyancy tank hanger 706, HDPE pipe plug ironware hanger 709, selector bar hanger 1405, and column obturator suspension ring 3, free suspending weight bridle ring 401, selector bar suspension ring 1404, this kind of member stress is large, damage impact large, in Offshore Engineering Components classification, belong to special class and a class, postwelding will do ultrasonic examination inspection, net cage cost of manufacture is limit and can not be applied mechanically ocean engineering requirement, but following requirements is reasonable, feasible, should strictly observe in making:

A. should strictly observe building process, Material selec-tion should select the steel that solderability is good, welding link should have perfect welding procedure, weld seam detection program, and welding personnel should hold qualified welder's certificate, forbids without card or rank deficient personnel welding.

B. strict construction in line with the drawings understand design idea, as in Fig. 10, by A enlarged diagram, clear to describe hanger anti-shearing, anti-tear strengthening measure, and this is the summary of experience of inventor in ocean engineering long-term practice, not at all can be careless in making, the hanger assembly 2 violated as general, is not directly welded with cylinder by hanger base 202, is exactly the example of this class Wrong mistake.

2. the installation of dissipation energy hinge: the dissipation energy hinge technology that the utility model has been introduced Modern Steel Structure antidetonation and developed, when effect is load accidental peak value, the energy of input is consumed by friction energy-dissipating pad, effect size depends on power consumption pad quality, and the product that the existing special rubber of viscoplasticity is made at present can for selecting.Another factor of effect size is the frictional force that requirement provides enough large, and because frictional force is that pressure at right angle takes advantage of coefficient of friction, therefore, have enough large pressure at right angle, be exactly here the fastening force of bolt, requires for this reason:

A. select qualified high-strength bolt, select the maximum gauge of bolt adaptation according to connecting plate bearing capacity.

B. the special spanner of high-strength bolt tightens nut, makes bolt produce huge and in check pretension.

What here we adopted is high-strength bolt pressure-bearing type, be intended that under wave force peak action, after having consumed power consumption pad completely by friction, dissipation energy hinge becomes two-way movable hinge, Here it is shackle plate and connect the reason that ironware will make straight elongated slot or arc elongated slot, also make net cage become quasi-flexible by this way, greatly improve capacity of anti-storm.

Band is adjusted and is carried the modular converter assembly of function, and water surface management small-sized net cage assembly is except the installation of above-mentioned dissipation energy hinge is different from routine, all the other all with existing net cage manufacture craft roughly the same, need not repeat again.

After completing each structure manufacture by land, the Attention problems stage can be proceeded to, what need discussion is installation method, overall transportation by lighter as resembled the deck of offshore platform by figure assembling, overall input, though simple and easy to do, need mobilize crane barge to assist operation, this will produce considerable expense, unbecoming with net cage cost of manufacture.What introduce below is from floating from mounting technique, and it only requires that two canoes and a diver assist.

1. first install float-type anchoring system 24 at assigned address, fasten mooring line 11, fasten mark ball float with net cage link;
