Description
Technical field：
The present invention relates to net cage for sea farming, more particularly, to a kind of single-point anchor fixed with etting with power pooling feature
Pool formula net cage.
Background technology：
About 16,000,000 hectares of oceanic area within China's 20m isobaths, the oceanic area about 50,000,000 within 40m isobaths is public
Hectare, the development space of sea-farming is huge.Greatly develop the deep-water net cage cultures more than 20 m depth of waters, to ocean ask for resource,
Widen living space, development " aquafarm ", set up " marine silo ", be solve new way that China's food supply ensures it
One.
Deep water mesh cage industry is one of important innovations type industry that China's fishery is strided forward to modernization fishery.Aquaculture net cage one
As constituted by net cage frame system, netting system, mooring system and auxiliary facility system four are most of.On seawater cage system
Technology development, merit attention the problem of following several respects：
First, the anchoring approach of net cage：
Traditional net cage is using the lineal anchor method of multiple spot, to tackle the influence from uncertain wind direction to net cage, and such as single case is used
6 anchor point methods, one anchor of every 60 degree of settings, whichever direction carrys out wind, there is the effect of at least 2 anchorages.Chinese patent mandate is public
The net cage of the announcements such as announcement CN1176578C, CN204949099U, CN204949120U is typical multiple spot anchoring approach.This
Class multiple spot mooring system has that difficulty of construction is big, construction quality is difficult to ensure that, efficiency is low, cost is high, Maintenance Difficulty limitation,
Phenomenon is damaged under larger stormy waves load action more serious.
In order to comply with the development of deep water mesh cage, single point mooring system is progressively developed.It is single compared with multiple spot mooring system
The characteristics of point mooring system has that anti-typhoon capacity is strong, it is simple and direct, cost-effective to construct, saves sea area resources, is deep water mesh cage hair
The major technique direction of exhibition.Such as Chinese patent Authorization Notice No. CN104186383B, CN104604768B, CN104186381B
The embodiment of announcement is typical single-point anchoring approach.
But common single point mooring system and the usual only one of which tie point of net cage frame, mooring point, cause the junction
Load-bearing is big, stress concentration phenomenon is serious, although consolidation process has been carried out at the mooring point of net cage frame, but under bad working environments
Still easily cause collapsing, fracture and damaging for net cage frame.
2nd, the volumetric loss rate of etting：
Netting system, which is mainly, crosses a breeding water body keeping breeding fish activity.If seawater velocity is very fast, etting usually can
Floating is indefinite and inwardly gathers, and causes the breeding spaces of net cage to diminish, aquatic products scope of activities diminishes, and water oxygen level declines, water
Matter declines, and then induces the generation of various diseases.
The country finds that seawater velocity still causes the change of cage netting volume to maximum effect of net cage by experimental study
Small, during flow velocity 0.5m/s, the volumetric loss rate of net cage is 30% or so；As flow velocity 1.0m/s, the volumetric loss rate of net cage is
50% or so；As flow velocity 1.5m/s, the volumetric loss rate of net cage is 70% or so.It can be seen that, how to reduce the volumetric loss of net cage,
It is to improve one of key technology of cage culture single rate.
At present, generally pressed in order to avoid etting because flow action assembles together and extrudes cultivation object in etting bottom
One determining deviation ties serial sinker, or is put into net cage the support ring of annular, and support ring sinks to net cage bottom, can prevent net
Clothing is inwardly gathered.But when changing etting, cleaning etting or drawing in the net to receive fish, it is necessary to which diver's diving goes to the bottom that sinker is being received into net
It is preceding first to pull out the water surface, or support ring is taken out, the recruitment used time is added, and then aquaculture cost is added, and operating efficiency is relatively low.
It can be seen that, it would be highly desirable to the fixing device of deep water net cage net clothing is improved, to reduce deep-water net cage culture cost, work effect is improved
Rate.
3rd, the pooling feature of anchor chain：
Conventional anchor chain is formed by many steel chain link linkings, is divided into cast steel anchor chain, Flash Butt Welding anchor chain, forging by manufacture method
Anchor chain is made, is divided into stud link chain cable and studless cable by chain link structure.Anchor chain can be made up of some " sections ", with chain link or be unloaded between section and section
Button is connected.The intensity of anchor chain is larger, and its deformation occurred under external force can be ignored compared with current displacement, dereliction
Energy is consumed, similar to being rigidly connected.
When marine stormy waves is larger, net cage is by larger impact load, with high frequency oscillation phenomenon.Because anchor chain is tightened
Length no longer changes afterwards, and impact load is without buffering energy dissipating so that net cage frame and anchoring basis hold under larger wind wave action
Easily destroy.
If if the elastic deformation of certain amplitude can occur in loading process for anchor chain, actively adapting to the higher-order of oscillation and impact lotus
Carry, absorbed by elastic deformation, consume part stormy waves impact energy, original size can be recovered again when stormy waves is smaller, with dynamic
Power pooling feature, similar to flexible connection, this is necessarily favourable to improving the security of net cage or anchoring basis.

Embodiment：
Referring to accompanying drawing:
Net cage is general to be made up of anchor chain, anchoring basis 11, float tube framework 1, etting 2 and sinker 10 etc., wherein mooring system one end
Connect float tube framework 1, other end connection anchoring basis 11." single point mooring system " there are no specification, unified definition, the present invention
" the single-point anchoring type net cage " carried, its implication refers to that the one end on mooring system connection anchoring basis only has a mooring point, anchor
Pool basis（Or underlying group）It is connected by a mooring point with anchor chain, there can be complexity between basic (or underlying group) inside
Interconnection mode, but basic (or underlying group) be connected eventually as one entirely through a mooring point with anchor chain.Single-point anchor
In pool system, the other end that anchor chain is connected with net cage can be a mooring point or multiple mooring points.The present invention is carried
The mooring system of net cage, its one end is connected by the basic phase 11 of a mooring point and anchoring, and the other end passes through multiple mooring points and net
Case is connected, and belongs to the category of single-point anchoring approach.Correspondingly, multiple spot mooring system refers to anchoring basic (or underlying group) by many
Individual mooring point is connected with multiple anchor chains, and the other end of multiple anchor chains connects net cage jointly by multiple mooring points.
The single-point anchoring type net cage with power pooling feature, including anchoring basis 11, anchor chain, float tube framework are fixed with etting
1st, etting 2, sinker 10 etc., it is characterised in that：The surrounding of etting 2 is uniform, symmetrical setting multiple row and same plumb line are coaxial
Hollow sleeve 3；The net cage system also includes elastic component force frame 4, and elastic component force frame 4 presses axle by multiple elastic fan blades in root
Symmetrical to be welded, the end of elastic fan blades sets mooring hole 6, and the convex surface of the symmetrical centre of elastic component force frame 4 sets mooring
Ring 5；The anchor chain includes one-level anchor chain 7 and secondary anchor chain 8, and one end mooring of one-level anchor chain 7 is on anchoring basis 11, one-level anchor
The other end mooring of chain 7 is on the mooring ring 5 of elastic component force frame 4, and secondary anchor chain 8 is through one end mooring after each row sleeve pipe 3 in float tube
On framework 1, the other end mooring of secondary anchor chain 8 is on the mooring hole 6 of elastic component force frame 4.
" the one-level anchor chain " that the present invention is carried refers in the anchor chain being joined directly together with anchoring basis, single point mooring system only
Unique one " one-level anchor chain " is joined directly together with anchoring basis；" secondary anchor chain " refers to net cage load to be directly passed to " one
The anchor chain of level anchor chain ".In the present invention, the one end of " secondary anchor chain " is connected by elastic component force frame 4 with " one-level anchor chain ", and " two
The other end of level anchor chain " is directly connected with the float tube framework 1 of net cage, as shown in Figures 6 and 7.
The length of anchor chain at the same level should be identical so that whole mooring system is in symmetry status substantially when calm.Such as Fig. 6
In four equal lengths of secondary anchor chain 8.
Symmetrical on etting 2, the uniform sleeve pipe 3 for setting multiple row coaxial with same plumb line, secondary anchor chain 8 through each column and
It is connected again with float tube framework 1 after the coaxial sleeve pipe 3 of same plumb line, as shown in Figure 6.Sleeve pipe 3 it is general by pvc pipe be made it is straight
Pipe.Preferably, the internal diameter of sleeve pipe 3 is more than more than twice of the external diameter of secondary anchor chain 8, and the length of sleeve pipe 3 takes 10cm ~ 50cm.Therefore root
According to the depth and the length of sleeve pipe 3 of etting 2, it may be determined that the quantity needed for each column coaxial sleeve 3.
Each row on etting 2 and the coaxial sleeve pipe 3 of same plumb line are uniform, symmetrical on the wall of circumference four of etting 2,
Preferably, the coaxial sleeve 3 on the circumference of etting 2 is no less than four row.Etting as shown in Figure 1 is uniform, symmetrical there is provided four row
Coaxial sleeve 3.
The effect of sleeve pipe 3 is：Secondary anchor chain 8 is entangled by the series sleeve 3 on etting 2, secondary anchor chain 8 is turned into maintenance
The skeleton of the volume of etting 2, in view of multiple secondary anchor chains 8 are parallel to each other and bear to be in straight condition after mooring forces, it can bear
Larger horizontal force, therefore can substantially reduce the volumetric loss rate of etting 2.
Even if net cage is produced larger inclination, but now all secondary anchor chains 8 by secondary anchor chain 8 is made after stormy waves load action
Still it is substantially parallel to each other, is tilted jointly to direction, the connection of sleeve pipe 3 makes etting 2 also produce with secondary anchor chain 8 same to incline
Tiltedly, the fixation of secondary anchor chain 8, restraining function make four walls of etting 2 mutually to gather, thus the volumetric loss rate of etting 2 compared with
It is small, as shown in Figure 9.
Because each row sleeve pipe 3 and same plumb line are coaxial and internal diameter is more than secondary anchor chain 8, therefore change etting, cleaning etting
Or when drawing in the net to receive fish, being pulled upwardly for etting 2 can't produce larger friction with secondary anchor chain 8.I.e. each row sleeve pipe 3 and two grades
Frictional force between anchor chain 8 is very small, and it is pulled upwardly operation substantially without influence to etting 2.It can be seen that, the setting one of sleeve pipe 3
Aspect can effectively safeguard the volume of etting 2, on the other hand be pulled upwardly operation without influence to etting.
In addition, the bottom of etting 2 still needs to set multiple sinkers 10, its effect is that etting 2 is stretched downwards, safeguards etting 2
Dischargeable capacity.But in the present invention there is significant difference in the effect of sinker 10 used and traditional net cage sinker：Traditional net cage is complete
It is complete to stretch etting downwards by the Action of Gravity Field of sinker, etting is maintained larger volume under action of ocean current, therefore institute
Need that the quantity of sinker is more, cumulative weight is larger；And the etting in the present invention is not dependent on sinker to maintain plot ratio (to rely on two
Level anchor chain 8 maintains plot ratio), sinker only plays a part of stretching etting downwards, therefore the negligible amounts of required sinker, accumulative weight
Amount is smaller, contributes to the pull-up operation of etting.
It can be seen that, the present invention is carried sets sleeve pipe 3 to be inserted in the mentality of designing of secondary anchor chain 8 on etting 2, on the one hand can effectively tie up
The plot ratio of etting 2 is held, on the other hand also greatly reduces the quantity and weight of sinker 10, alleviates etting and be pulled upwardly operation
Difficulty, it is clear that more meet the growth requirement of deep water mesh cage.
Elastic component force frame 4 is welded by multiple elastic fan blades in root by axial symmetry distribution, during elastic component force frame 4 is symmetrical
The convex surface of the heart sets mooring ring 5, as shown in Figure 2.Elastic fan blades is made up of high intensity, elastomeric material, and overall is in arc-shaped,
The width of elastic fan blades is gradually reduced by root to end, and the end of elastic fan blades sets mooring hole 6, as shown in Figure 3.
Mooring hole 6 in the axisymmetricly state of elastic component force frame 4, each elastic fan blades on same circumference, the circumference
Diameter is slightly larger than the diameter of etting 2, can preferably extend the volume of etting 2.Preferably, elasticity fan on elastic component force frame 4
The quantity of piece is no less than four.
Can occur larger elastic deformation after the load-bearing of elastic component force frame 4, the initial configuration of elastic component force frame 4 as shown in Fig. 2
Configuration after stress deformation is as shown in Figure 4.Position 9 after the elastic deformation of elastic component force frame 4 is in symmetry status still with mooring ring 5,
As shown in Figure 5.Elastic component force frame 4 has larger intensity and elasticity, and larger elastic deformation can occur when load-bearing is larger；
When load reduces, elastic component force frame 4 can recover certain elastic deformation；When calm, elastic component force frame 4 keeps former substantially
Beginning shape.Specifically, elastic component force frame 4 should have sufficiently large intensity, be not plastically deformed under bad working environments, fracture with
Damage；Meanwhile, elastic component force frame 4 should have sufficiently large elasticity, and significant elasticity can occur under larger stormy waves load action
Deformation, realizes power pooling feature.
When stormy waves load is larger, larger elastic deformation can occur for elastic component force frame 4；When stormy waves load diminishes or in ripple
Gu Shi, elastic component force frame 4 can recover certain deformation using off time.Because wind wave action often has intermittent, crest
Trough characteristic, therefore elastic elongation can occur under periodicity wind wave action for elastic component force frame 4 with shortening periodically deforming, can inhale
Receive, consumption part stormy waves impact energy, there is peak clipping to stormy waves load, subtract peak effect, thus reduce stormy waves load to net cage and
The harm on anchoring basis.And traditional steel anchor chain, it can not deform, the transmission of the larger direct single-candidate of stormy waves load
To net cage and anchoring basis, the security threat to net cage and anchoring basis is larger.
During connection, one end mooring of one-level anchor chain 7 is on anchoring basis 11, and other end mooring is elastic component force frame 4
Moor on ring 5；Secondary anchor chain 8 is passed through after each row sleeve pipe 3, and one end mooring of secondary anchor chain 8 is on float tube framework 1, other end mooring
On the mooring hole 6 of elastic component force frame 4.The stormy waves load that net cage is subject to by each transfer elastic component frame 4 of secondary anchor chain 8, then
Load is passed to by elastic component force frame 4 by one-level anchor chain 7, and then passes to anchoring basis 11.Therefore elastic component force frame 4 is played
The effect of " forming a connecting link ", its intensity should meet the transmission needs of load under bad working environments, not stress concentrate occur flexing with
Failure.
When calm, under the weight effect of elastic component force frame 4 and each secondary anchor chain 8, each secondary anchor chain 8 is in vertical
State, therefore etting 2 is also at the maximum extended position of volume, as shown in Figure 6.During stormy waves load action, etting run-off the straight, by
Fixation, restraining function in 4 pairs of each secondary anchor chains 8 of elastic component force frame make each secondary anchor chain 8 still in substantially parallel skewed
State, the sleeve pipe 3 being enclosed on each secondary anchor chain 8 makes etting 2 occur basically identical heeling condition, each two grades with each secondary anchor chain 8
The restraining function of anchor chain 8 makes four walls of etting 2 can not mutually gather, compress breeding spaces, as shown in Figure 9.
The mooring point quantity of anchor chain and net cage frame is equal to the quantity of secondary anchor chain.The quantity of secondary anchor chain is no less than four
Bar, and be uniformly distributed along net cage frame surrounding.I.e. the quantity of mooring point is no less than four, and uniformly divides along net cage frame surrounding
Cloth, the design can greatly reduce the stress concentration at net cage float tube framework mooring point, and the stormy waves load that net cage is born passes through many
Individual mooring point passes to a plurality of secondary anchor chain, effectively increases the security of net cage float tube framework.It can be seen that, carry net cage system and adopt
With single point mooring system, but not mooring point in net cage frame, junction produce larger stress concentration.
The secondary anchor chain 8 of varying number can be used according to actual needs, and several embodiments are described below.
Embodiment 1：Along the sleeve pipe 3 that the surrounding of etting 2 is uniform, the symmetrical row of setting four are coaxial with four plumb lines, such as Fig. 1
It is shown.Correspondingly, fan blades is axisymmetric is welded by four elasticity for elastic component force frame 4, as shown in Figure 2.Four secondary anchors
Chain 8 passes through corresponding four row sleeve pipe 3, and one end mooring of secondary anchor chain 8 is on float tube framework 1, and other end mooring is in elastic component force
On the mooring hole 6 of frame 4.One end mooring of one-level anchor chain 7 is on anchoring basis 11, and other end mooring is elastic component force frame 4
Moor on ring 5.The length of secondary anchor chain 8 should be greater than the depth of net cage.A kind of band etting is so constituted to fix and power pooling feature
Single-point anchoring type net cage, as shown in Figure 7.
In the present embodiment, making a concerted effort for four secondary anchor chains 8 is equal with the pulling force of one-level anchor chain 7, therefore the material of secondary anchor chain 8
Intensity, cross-sectional dimension are smaller than the strength of materials of one-level anchor chain 7, cross-sectional dimension.Therefore can be according to the stress feelings of anchor chains at different levels
Condition, designs matched material parameter, makes the safety coefficient of anchor chains at different levels essentially identical, reach the purpose of optimization design.
Embodiment 2：The five row sleeve pipe 3 coaxial with five plumb lines uniformly, is symmetrically set along the surrounding of etting 2, accordingly
The elastic component force frame 4 that ground is welded using five elastic fan blades axial symmetry is attached, connection method be the same as Example 1.
Embodiment 3：The six row sleeve pipe 3 coaxial with six plumb lines uniformly, is symmetrically set along the surrounding of etting 2, accordingly
The elastic component force frame 4 that ground is welded using six elastic fan blades axial symmetry is attached, connection method be the same as Example 1.
According to above-mentioned thinking, more way of example can also be derived, it is no longer exhaustive herein.
The present invention first its use single point mooring system, but not produce at the mooring point of net cage frame larger stress
Concentrate；Secondly it can effectively reduce the volumetric loss rate of net cage, and etting replacing, etting are cleaned or drawn in the net to receive fish j ob impact
Less；It has power pooling feature again, and larger elastic deformation can occur under wind wave action, can effectively protect net cage with
Anchoring basis, can improve net cage and the capacity of anti-storm on anchoring basis.
