Description
Technical field
With the buoyancy pillar deep water mesh cage of rigidity walkway board flexible structure, be that a kind of ocean current that is applicable to is anxious and without the novel net cage in the open sea area of shield, belong to ocean engineering field.
Background technology
Cage culture is the pith of marine economy, gravity type high-density polyethylene (HDPE) the material net cage of being introduced by Norway at present develops rapidly, in the yellow Bohai Sea, the East Sea, the South Sea, have a large amount of raisers to use, this gravity type net box made from HDPE material, although the tube frame of making by HDPE, by note/drainpipe is set, before typhoon, can be sunken to certain depth, evade the wave stroke of waterline, but still have following fatal defect from this net cage of practice:
1. be not suitable with the impact of ocean current, when current speed only reaches 0.257m/s according to observations, just may deform, in the time that flow velocity reaches 1m/s, will lose 80% cage culture and hold body, cause cultivation fish extruding death in net cage.
2. because this class 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 in gulf water quality 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, on the other hand due to water pollution, cause large area raising fish and shrimp pond on the bank to lie waste, this just forces local government for city development, the inner bay cage culture family of having to go by force to drive, but because of the technical support that does not have open waters to use, this just makes raiser in very difficult condition.
The not corresponding reliable anchoring anchoring system of 3.HDPE net cage is supporting, this with tension type net cage taking reliable anchoring mooring as prerequisite different, anchoring and mooring problem do not solve always, so that pass through under typhoon to sink, 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 to off-lying sea and is lost, half blows to bank and batters down, one of the fish of fast results is not all got back, only the economic loss of three companies nearby 800,000,000.
4.HDPE net cage is by HDPE material, be that the large-diameter pipe that high density polyethylene (HDPE) is made is processed into annulus, make buoyancy and the supporting member of net cage, its loading characteristic is still similar to a pipeline, bent flat be that unstability remains one of principal mode that its destroys, in August, 2013 typhoon " especially " blow Yangjiang, Guangdong, cause local net cage to be annihilated, Lingao, Hainan fish culture net cage is different in by the end of September, 2011 with, the net cage anchoring mooring of Yangjiang, Guangdong is better, but under the rotation action of ocean current that HDPE Net-cage frame causes at typhoon, presenting HDPE pipe component song flat is unstable failure, the destiny of being annihilated equally.
From the cage culture of upper analysis development open waters, need to break through the limitation of HDPE net cage, seek a kind of safety, reliable, Anti-Typhoon, be applicable to ocean current anxious and without the novel net cage in the open sea area of shield, the utilization of resources in vast marine site is got up.According to domestic and international existing experience and theory analysis, improved route has:
1. fixed anchor strut system, by net cage mooring Zhang tightly on anchor strut, ocean current can not cause the drift of net cage undoubtedly, cause cage culture to hold bulk diffusion, but fixed anchor strut must have reliable anchoring, and realize version and the construction method of this anchoring, but this is a difficult problem, because by conventional pile foundation, because introducing marine guidance piling, expensive operation on the sea expense, just makes this scheme meaningless.
2. tension leg type net cage, tightens net cage by tension force, can make equally ocean current can not cause the drift of net cage, causes cage culture to hold bulk diffusion, but brings two problems:
A. to there is the basis of the reliable anchoring of high withdrawal resistance of balance tension, if aforementioned this is a difficult problem;
B. to have and produce enough structures of large buoyancy, in ocean engineering specialty, be called " buoyancy compartment ", according to the ancient law of Archimedes, buoyancy is exactly the weight that buoyancy aid is got rid of water body, if flood tide, ebb tide all ensures its tension force, only has a way, while allowing net cage be placed in low tide under water, this just brings operational inconvenience, as feeding, fish for, reject the inconvenience of the operations such as Si Fish.
In order to break through the limitation of HDPE net cage, seek a kind of safety, reliable, Anti-Typhoon, be applicable to ocean current anxious and without the novel net cage in the open sea area of shield, just must be taking tension leg type net cage as basis, the core of getting its tension force, changes the inconvenient shortcoming of its operating surface, retain gravity type HDPE net cage simultaneously, by note/drainpipe is set, before typhoon, can be sunken to certain depth, evade the effective Anti-Typhoon way of wave stroke of waterline.Researched and developed by inventor herein, oneself obtains the patent of being authorized " can be with the tension leg type deep water mesh cage of fluctuation in stage heave " (patent No. 201320095246.2) illustrated principle and the feature of tension leg type deep water mesh cage comprehensively, a new construction that is better than external tension leg type deep water mesh cage has been proposed, but the same with external tension leg type deep water mesh cage, still adopt the scheme of rigid backbone, though be applicable to conventional water body net cage, but be unfavorable for constructing large-scale or ultra-large type tension leg type deep water mesh cage, researched and developed by inventor herein, oneself obtains another patent of being authorized " air bag regulates the buoyancy can be with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " (patent No. 201320623481.2), the indignant thought of buoyancy post based on offshore oil Spar Platform theory has been proposed, surround Net-cage frame with four jiaos of upper and lower stretch-draw cables of buoyancy post, replace the flexible structure scheme of rigid connector with buoyant rope, not only thoroughly having solved structure song flat is destabilization problems, also construct easily large-scale or ultra-large type tension leg type deep water mesh cage, simultaneously owing to hanging one group of concrete ballast piece under hanger at the bottom of post, be configured to ballast balance cabin, make structural focus be positioned at below, centre of buoyancy and there is permanent stability, under severe marine environment condition, safety has unrivaled advantage, therefore, it is a wind wave resistance, the novel net cage that anti-ocean current performance is unsurpassed in excellence.This patent exists " air bag regulates the buoyancy can be with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " on basis, improve the rigidity of the walkway board of former patent, thereby improve operating personnel's operating condition, buoyancy post is by variable buoyancy compartment simultaneously, permanent buoyant tank and ballast tank are arranged on same cylindrical shell, thereby using under barge container traffic condition, can greatly accelerate installation progress, and patent " air bag regulates the buoyancy can be with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " buoyancy post transportation by driving+ballast tank transportation by lighter (advantage is not need barge container) difference, having ready conditions under use barge container traffic condition, marine installation is simpler and more direct sooner, therefore, this patent be to " can be with the tension leg type deep water mesh cage of fluctuation in stage heave " (patent No. 201320095246.2) and " air bag regulates the buoyancy can be with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " useful the supplementing of the patent No. 201320623481.2, make tension leg type deep water mesh cage have the value of broader applications, and provide user the selection space larger according to self-condition.

summary of the invention
In order to seek a kind of safety, reliably, Anti-Typhoon, be applicable to urgency and the open sea area without shield of ocean current, easy to operate novel net cage, realize the circumscribed breakthrough of HDPE net cage, the technical solution of the utility model be taking " air bag regulates the buoyancy can be with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " patent No. 201320623481.2 is for basic, takes following technique measures:
1. the oval cylindrical shell of steel buoyancy post, be divided into variable buoyancy compartment from top to bottom with steel plate, permanent buoyant tank and ballast tank, variable buoyancy compartment is at top, note/draining pipe valve and the note/blow off valve installed by casing top, realize variable buoyancy function, permanent buoyant tank is the safety of guaranteeing buoyancy, filling polyvinyl chloride or polyurethane foaming body, ballast tank is by the perfusion pore with cover of installing, inject iron sand or iron ore ballast or the heavy pulverizing body of other quality by perfusion pore, the longitudinal use of steel buoyancy post is no less than 4 elongated steel pipes or shaped steel is strengthened, and one determining deviation reinforcing ring is set, simplified bottom is welded with anti-settling, also can be used for support and adjust the end boots of weight piece, between two posts, couple together formation Net-cage frame with upper and lower two layers of cable with float, so just form and be different from the flexible structure that rigid member connects,
2. in order to improve operating personnel's operating condition, adjoin mutually buoyancy intercolumniation rigidity buoyancy walkway board, connect and couple together by dumpling;
3. for buoyancy cylinder does not have large departing from high sea, shaft retrains with hawser, and it is upper that hawser one end is fixed on basis, and basis can be stake or anchor, and the hawser other end is fixed on cylinder hanger;
To point out especially: in the time of the ratio d/ λ > 0.5 of the depth of water and wavelength, be deep-water weave, water body particle is to follow circular trace motion, radius of circle is decayed downwards from the water surface by exponential law, the horizontal velocity component of water particle is in water surface maximum, sharply reduce along with the depth of water, the water-filling dive successful of net cage, but be Very Shallow Water ripple in the time of d/ λ≤0.05, water particle is almost horizontal trajectory and moves back and forth, its velocity level's component is almost constant from the water surface to the bottom, in the time of 0.05 < d/ λ≤0.5, it is shallow-water wave, water particle track is an ellipse, horizontal velocity along the attenuation rate of the depth of water between deep-water weave and Very Shallow Water ripple between the two, therefore in shallow-water wave district (depth of water < 20m), the water-filling dive effect of net cage is not large especially, now, just meaningful especially to net cage constraint with hawser.
4. buoyancy cylinder can arrange some hanging members as hanger according to purposes, and suspension ring are for heaving pile and be net cage etc.;
5. phase O buoyancy cylinder central authorities arrange multi-functional conversion piece casing, it had both facilitated cable series winding, can be used as again a mooring point, simultaneously can be again manager provides a little operating platform, and the small-sized net cage that is less than or equal to 20m (girth 80m) for the length of side can not established and change piece casing;
6. the anti-boots that sink to the bottom of cylinder body bottom, also can be used for support and adjust weight piece, adjust weight piece to can be the heavy block such as cobble cage and sand bag of concrete block or flood control use.
This technical scheme principle is, enough the buoyancy compartment of large buoyancy with enough greatly the ballast tank of ballast couple together, the two is after poised state, between buoyancy compartment and ballast tank, just produce tension force, as shown in Figure 1, H is wind, wave, the horizontal force producing under flowing common action, it departs from buoyancy aid generation, if the tilting complex torque M-that horizontal force H produces, it is M+ that buoyancy F produces righting moment, and the two is just in time reverse, and tension force can make it get back to equalization point by acting in opposition, thereby realize dynamic equilibrium, the principle of compliant type anchoring that Here it is.In the time that water level changes, buoyancy changes, and buoyancy compartment is together with the just upper and lower heave of ballast tank.Before attacking, typhoon allow it sink down into sea bed face by variable buoyancy compartment water filling, typhoon allows its floating restore toward variable buoyancy compartment gas injection draining later, be not both with HDPE, this patent net cage can dive arrive sea bed face, the end boots anti-settling by buoyancy post are located in sea bed face, and keep etting bottom surface not touch the end, thereby safer.
The utility model has the advantages that rational in infrastructure, safety is good, structurelessness song is flat is destabilization problems, workable, overcome the inconvenient shortcoming of foreign same type total flooding tension leg type net cage operating surface completely, have again the reliable mechanism of evading typhoon, this technical scheme is beneficial to the large-scale or ultra-large type deep water mesh cage of structure simultaneously, and this is just for exploitation ocean current is anxious and created condition without the culture resources in the open sea area of shield.

Embodiment
Because cylinder 1 diameter is larger, be generally rolled into tubulose by steel plate and weld again longitudinal joint, the program of now should pressing is carried out:
A. setting-out cutting;
B. veneer reeling machine roll bending moulding;
C. the groove of polishing;
D. longitudinal seam automatic welding or manual welding are made welded pipe;
E. other annex of welding cylinder;
F. weld inspection, available magnetic powder inspection sampling observation, can do ultrasonic examination sampling observation as having ready conditions.
On cylinder 1, miscellaneous part making is conventional steel construction operation, do not have any difficult point and special character, difference is that requirement is higher compared with land light-duty steel construction house operation, should strictly observe building process, material should be selected the steel that solderability is good on selecting, and in welding link, should have perfect welding procedure, weld seam detection program, welding personnel should be held qualified welder's certificate, forbids without card or rank deficient personnel welding.
To point out especially the importance that shaft hanger 16 welds, in the C of Fig. 8 enlarged diagram, clear explained as the hanger of important component anti-shearing, anti-tear strengthening measure, not at all can be careless careless in making, as the general hanger of violating 16 does not directly miss with the Wrong of cylinder welding by hanger base 18, its disastrous effect is under huge pulling force effect, because cylinder wall thickness produces avulsion compared with the thin or anti-lamellar tearing performance of steel is bad.Certainly as the dicyclic hanger of conversion block casing is directly welded on box body wall and is also fine, be mainly that this box body wall can be thicker a little in addition because stressed less.
Cylinder 1 is made place will adapt to the rear lower water mode of buoyancy cylinder completion: the one, and barge loads and transports to erecting bed, and this just requires fabricating yard the harbour of barge alongside.The 2nd, transportation by driving is to erecting bed, and this just requires fabricating yard and have to pass buoyancy cylinder and enter the ramp of water, as small-sized shipyard arranges marine railway.
If erecting bed is plant, offshore is not far, and transportation by driving is good method, but should configure buoyancy tube, respectively bundlees buoyancy cylinder in buoyancy post ballast tank (loading iron sand cabin) two sides, its buoyancy post is put down and float on the surface.
Complete by land and turn conversion block casing 28, rigidity buoyancy walkway board assembly 26, net cage bottom support framework 32 is made, and these parts are made and are routine, there is no special feature, so do not narrate.
Purchase the corresponding upper and lower cable 23,24 of net cage and etting 31, so far, the land preparation of net cage body completes.
Land another preparation is mooring foundation, and basic 33 forms are not restricted.
Entering the marine embodiment of installing is:
