Description

The tension leg structure HDPE net cage of mixed type is reinforced from mooring float tube

Technical field

Reinforce the tension leg structure HDPE net cage of mixed type from mooring float tube, be a kind of new-type environment-friendly type net cage being applicable to the comparatively anxious and unscreened open sea area of ocean current, belong to ocean engineering field.

Technical background

Cage culture is the pith of marine economy, the net cage that the high density polyethylene (HDPE) introduced by Norway is at present called for short HDPE making develops rapidly, in the yellow Bohai Sea, the East Sea, the South Sea, has a large amount of raiser to use, this floating cage made with HDPE material, there is operation interface good, poultry feeders feeding, rejects dead fish, draping clothing, receipts fishes etc. are all very convenient, add that cost is moderate, therefore welcome by fisherman very much, so monopolized cage culture EQUIPMENT MARKET GUIDE from south to north, sum reaches ten thousand mouthfuls, defines huge industrial chain.Although the tube frame of HDPE making at present, by arranging note/drainpipe, can be sunken to certain depth, evading the wave stroke that the water surface is maximum before typhoon, 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 1m/s, body is held in loss 80% cage culture, so just lose the culture resources of a large amount of more high-quality.

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, and this just forces local government in order to city development, has to go by force to drive inner bay cage culture family, but the technical support used because not having open waters, this just makes raiser be in very difficult condition.

3. although the tube frame that made by HDPE of floating type HDPE net cage, by arranging note/drainpipe, submersible in certain depth before typhoon, by strutured lipid can not dive to seabed, resemble to reach dish-like net cage and optimally evade typhoon position.

4. although the tube frame that made by HDPE of floating type HDPE net cage, by arranging note/drainpipe, submersible in certain depth before typhoon, evade the wave stroke that the water surface is maximum, but from this net cage capacity of anti-storm of practice, and desirable like that not as introducing:

A.2011 year by the end of September Lingao, Hainan at the fish culture net cage of open waters, at typhoon " Ni Ge " attack under be annihilated, the only economic loss of three companies nearby 800,000,000.

B.2013 August in year typhoon " especially " blow Yangjiang, Guangdong, cause local net cage to be annihilated.

C.2013 violent typhoon in September in year " Lepus " attacks Fujian Province, and according to Administration of Ocean and Fisheries of Zhangzhou City of Fujian Province statistics, local net cage is annihilated.Cause damage more than 5.6 hundred million yuan.

Cause this Disaster difficulty consequence, it is malfunctioning not to be that someone imputes valve erosion to, and raiser not to construct etc. construable on request, the destruction that this band is of overall importance, and illustrating will from the existing popular floating type HDPE net cage of re-examine structure.

Our research conclusion is: this destruction of overall importance has its source in 1. basis and the disappearances of anchoring system technology, as basic mooring force is too little, does not have supporting elasticity to subtract power and unloads power measure etc.2.HDPE net cage component intensity and rigidity too poor, with regard to intensity, HDPE material is less than prevailing A3 steel 1/10, and elastic modelling quantity is less than 1/200 of steel.3. the stability of entirety is poor too, and knot forms tabular, does once contrasting bright Liao with boats and ships or floating platform, special just more outstanding when net cage size is larger.Basis and anchoring system technology are another Iarge-scale system, should by another special subject study, and this patent is not discussed.

Tension leg type net cage TLC (TensionLegCages, referred to as TLC type net cage) oceanography institute of University Of Hainan anticipatory remark the 6th phase < < fishery modernization > > in 2002 writes articles < and introduces a kind of marine fish farming tension leg net cage > and 2003.2 again write articles in " China Fisheries economy " the inspiration > that < investigates Norway offshore tension leg fish culture in net pen subsequently, author is by the investigation to Norway's seawater cage, tension leg fish culture in net pen is proposed very suitable to China's southeastern coastal areas popularization, advantage author assessment for tension leg net cage is: 1. capacity of anti-storm is stronger.It is introduced, TLC type net cage has lived through the test of the high stormy waves of 11.7m wave, safe and sound.The simpler cost of 2 structure is lower.Tension leg net cage compares with flexible cylindrical and rigidity lowering double-cone net cage, and structure is simpler, thus reduces cost.

But domesticly do not introduce TLC net cage so far, reason fails, by economic measures, to solve the reliable anchorage problem of high withdrawal resistance of balance tension.The knowledge that inventor herein builds based on offshore platform and experience, propose a difficult problem for the reliable anchoring of high withdrawal resistance solving balance tension, and grind create series economic and practical, the tension leg type net cage of strong operability, in this patent by above-mentioned for reasonable combination technology, seek a kind of safer, more reliable, Anti-Typhoon, be applicable to the novel HDPE net cage in the comparatively anxious and unobstructed open sea area of ocean current, particularly do not rely on water filling to sink these technical measures, can resist strenuously live typhoon by net cage system, it is deep-water netted case resisting wind and wave truly, simultaneously in this patent will first in the world, the innovation scheme be combined with additional mooring from mooring is proposed, this tension leg type net cage for excellent performance is applied, for the HDPE enterprise forming huge industrial chain, can continue plays a role is far reaching.

Embodiment

Because the utility model skeleton has followed the essential structure of traditional HDPE, just four corners has infiltrated steel construction, but owing to being routine work, adds that clear explanation done again by drawing, as long as conscientious construction in line with the drawings, but should pay close attention to:

1. the making of hanger class: as main hanger assembly 9, float tube end steel plug assembly 2, this kind of member stress is large, damages impact large, in Offshore Engineering Components classification, belong to special class and a class, postwelding will do ultrasonic examination inspection, net cage makes and limit by cost, can not apply mechanically ocean engineering requirement, but following requirement is reasonable, feasible, should strictly observe in making:

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.

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

A. select qualified high-strength bolt, according to connecting plate bearing capacity, select the adaptive diameter of bolt.

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 the effect of peaking wave power, after having consumed power consumption pad completely by friction, dissipation energy hinge becomes simple hinge, connector is allowed to slide along groove, Here it is shackle plate and connect the reason that ironware will make straight elongated slot or arc elongated slot, also makes cage structure have by this way quasi-flexible, prevents its unstability.

3. the anticorrosion as structure has kinds of schemes available, and can be required to determine by service life and owner, because main body is HDPE material, steel beam column is few, is the most simple and effective way with suitably thickening.

After completing each structure manufacture by land, can proceed to the Attention problems stage, its program is:

1. install additional buoyancy block 504 at transition mast cover before descending water, buoyant mass is market commercialisation product, and market is bought.

2. first install outer anchoring system at assigned address, fasten mooring line 11, cable-end fastens mark ball float;

3. the utility model has taken into full account the operability of Attention problems, novel net cage drags emersion sea as HDPE, heavy concrete ballast carrier 405, bottom suspension hook, mount one or lineup's work fishing bank type pouring weight again, after release position, the short hawser 404 of connection of free suspending weight assembly, through transition mast chock 503, hang on transition mast link again, then hang or push water, each hawser is fastened under diver assists, fasten etting, so far Attention problems work is completed, note it being suspension hook bottom pouring weight 405, mount one or lineup's work fishing bank type pouring weight again, cable is long to be controlled except being tensioning state except high tide level, flat, between low tide two concrete ballast body, cable is lax.

To point out that artificial fishing bank type pouring weight can replace with building waste especially, with more environmental protection and saving.

Find out that from above Attention problems is similar with HDPE net cage, but the utility model can rise and fall, with fluctuation in stage heave, self-stabilization, multiple protective, mooring is more reliable, and ecological, environmental protective is economical and practical, is a desirable deep water mesh cage.
