Description

Tension leg type buoy mooring can floating anti-wind wave anti-ocean current environment-friendly type drift line type net cage

Technical field

Tension leg type buoy mooring can floating anti-wind wave anti-ocean current environment-friendly type drift line type net cage, it is a kind of novel drift line type net cage being applicable to the comparatively anxious and unobstructed open sea area of ocean current, present invention preserves drift line type net cage flexible structure without unstability risk, with low cost, make simple advantage, circulate again and can rise and fall, wind wave resistance, anti-ocean current, environment-friendly type advantage, significant to the modern mariculture of development.This technology belongs to ocean engineering field.

Background technology

Drift line type net cage is popular in Japan, and the mariculture equipment of TaiWan, China, has flexible structure without unstability risk, with low cost, make simple advantage, also have certain capacity of anti-storm (< storm), but be not suitable for the marginal basins district that typhoon takes place frequently.By means of oneself buoyancy pillar deep water mesh cage series of patents of being authorized of inventor herein as " air bag regulate buoyancy can with the flexible structure tension leg type deep water mesh cage of fluctuation in stage heave " (patent No. ZL201320623481.2) and " the buoyancy pillar deep water mesh cage of band rigidity walkway board flexible structure " (patent No. ZL 201420086550.5), " band damping is anti-swings plate semisubmersible platform type trip fishing cultivation dual-purpose flexible environment friendly net cage " (patent No.: ZL 201420319567.0), namely hold a little according to the only pillar platform of offshore oil (English by name SPAR), supporting buoyancy aid is made structure centre of buoyancy upper, center of gravity under, there is the buoyancy post of permanent stability and unconditional balance, buoyancy post connects with hawser, be fixed in anchoring system by the mooring of buoyancy post, etting is articulated on buoyancy post or buoyancy post hawser.Because buoyancy post is designed with sink-float function, therefore, net cage also has sink-float feature.

Plate scheme is swung in addition by the damping that the present inventor world is pioneering is anti-, environmental protection for breeding water body is extremely significant, because, cultivation Yu Dung just and residual bait drop on that damping is anti-swings 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.

In anchoring system, according to academician of the Chinese Academy of Engineering once Heng mono-and Wu Si and model mould senior engineer etc., patent (patent No. ZL95205025.0 now the lost efficacy)----tension leg type buoy mooring system of invention in one's early years, i.e. a kind of simple structure, there is the oil storage wheel mooring gear of favorable elasticity characteristic, if transformed on this basis, not only can replace the anchoring system of traditional drift line type net cage, also have other special benefits.

Therefore, according to above-mentioned achievement in research, by traditional drift line type net cage, may transform as and have and can rise and fall, wind wave resistance, anti-ocean current, and the new feature of environmental protection, and retain its original flexible structure without unstability risk, with low cost, make simple advantage, become the new equipment that the modern mariculture of development plays an important role.

Summary of the invention

In order to by traditional drift line type net cage, transform as and have and can rise and fall, wind wave resistance, anti-ocean current, and the new feature of environmental protection, and retain its original flexible structure without unstability risk, with low cost, make simple advantage, become the new equipment that the modern mariculture of development plays an important role, the technical solution of the utility model is:

1. steel or composite column obturator, end face is installed and is formed variable buoyancy compartment into/draining pipe valve and import/exhaust pipe valve, column obturator connects upper free suspending weight bar by bottom surface suspension ring, upper base shoe heavy concrete ballast carrier is overlapped bottom bar, thus form structure centre of buoyancy upper, center of gravity under, there is the buoyancy post of permanent stability and unconditional balance, upper and lower main push-towing rope rope is fastened at this buoyancy post, form four post list casees or the many casees of multicolumn, as eight post six casees, breeding net clothing corner is by etting main push-towing rope rope, as security measure, be bound on the upper and lower main push-towing rope rope of buoyancy post with hawser simultaneously, fasten stretch-draw damping at lower main push-towing rope rope to prevent swinging plate, lower main push-towing rope rope is hawser or float tube, damping is anti-swings plate composite material skin or curtain is made, damping is prevented swinging the buoyant mass of establishing the plastic foam material of perforate in the middle of plate, mooring line in the mooring of buoyancy post, mooring line other end is bound in tension leg type buoy mooring system.

2. four jiaos of buoyancy post mooring lines are connected by cable fastener with tension leg type buoy mooring system, and the annular main push-towing rope length that cable fastener is formed, meets the requirement of net cage dive sea bed or dive set depth.

The utility model, by integrating original patent achievement, makes traditional drift line type net cage, transform as and have and can rise and fall; wind wave resistance; anti-ocean current, and the new feature of environmental protection, and retain its original flexible structure without unstability risk; with low cost; make simple advantage, thus be greatly beneficial to and popularize, become and march deep-sea; benefit fisherman, the reliable equipment of protection of the environment.

Embodiment

Tension leg type buoy mooring can floating anti-wind wave anti-ocean current environment-friendly type drift line type net cage core be buoyancy post, and buoyancy post processes mainly column steel pipe and free suspending weight bar, and these are conventional processing, note it being hanger, the processing of suspension ring, conscientiously by figure processing, will understand the meaning of anchorage length.

Numbering 2 is column assembly 2 type, and it and column assembly 1 type are the difference of hanger number.

Cable fastener assembly screws freely except the meticulous guarantee of processing, will make Duplex treatment to anticorrosion, the zinc-plated or aluminium of first thermoelectricity, then on heavily anti-rotten Tu layer.

The composite material skin or the curtain 1301 that swing plate 13 are prevented in damping, and damping prevents that swinging plate connection keyhole 1302 etc. is commercial prod, and central authorities paste upper the anti-of perforate and swing plate floating block .

The Attention problems stage can be proceeded to after completing buoyancy post and annex making by land.Carrying out program is:

1. first install tension leg type buoy mooring system 14 at assigned address;

2. assemble buoyancy post with installing outpost by land, connect main push-towing rope rope 3, free suspending weight bar drawknot rope 12, etting main push-towing rope rope 5 and 6, damping is anti-swings plate assembly 13, with slip-knot, their bindings is hung on barge together; Hang on also having of barge to prevent sinking to the bottom shoe heavy concrete ballast carrier 408 simultaneously;

3. descend in water front hanging and prevent sinking to the bottom shoe heavy concrete ballast carrier 4;

4. buoyancy post is pushed water, untie slip-knot and each post is launched and is connected with float-type anchoring system 14, notice that main mooring line is by cable fastener assembly, and rear length is loosened in approval;

5. finely tune floading condition by variable buoyancy compartment 1, so far, complete Attention problems work, find out from above, this structure Attention problems advantage is fairly obvious.

At normal operation condition, because tension leg type buoy mooring system 14 has suspention net cage system function, therefore, the contingent of buoyancy post causes water inlet, also can not cause net cage dive, and only unclamping cable fastener could dive.When noting being typhoon dive, except will unclamping cable fastener, also to untie the mooring line of neutral buoyancy post.
