Specific embodiment：
Referring to accompanying drawing：
A kind of net cage mooring anchor chain adapting to the higher-order of oscillation and impact load, including common anchor chain 22 and elastic cable 21, elastic cable
21 are assembled by pull bar, two springs, staving, bottom shroudings, another by a under tension in two springs during mooring forces
One is under pressure, and enables elastic cable 21 that larger elastic displacement to occur, anchor chain 22 is connected group with multiple elastic cable 21 head and the tail
The net cage mooring system dressed up, has power pooling feature, favourable to the security improving net cage or anchoring basis.
The bottom shrouding 4 of elastic cable 21 is a circular steel plate, and surrounding is uniformly provided with connecting hole one（Bolt hole）5, circular steel
The side center of plate is provided with fix bar 2, and fix bar 2 end is provided with mooring ring 1, the handing-over of fix bar 2 and bottom shrouding 4
Place is uniformly provided with the ribbed stiffener 1 of four pieces of triangles, and the opposite side center of circular steel plate is provided with earrings 1.Mooring ring 1, solid
Integral by being welded to connect between fixed pole 2, ribbed stiffener 1, bottom shrouding 4, earrings 1.
One end of the pull bar 8 of elastic cable 21 is provided with mooring ring 7, and the other end of pull bar 8 is provided with the supporting plate 10 of circle, pull bar 8
It is uniformly provided with four pieces of triangle ribbed stiffeners 29 with the junction of circular supporting plate 10, the opposite side center of round pallet 10 sets
There is earrings 2 11.Integral by being welded to connect between mooring ring 7, pull bar 8, ribbed stiffener 29, round pallet 10, earrings 2 11.
The staving 13 of elastic cable 21 is a steel hollow circular cylinder with top board, and its top board central axis is provided with preformed hole
12, hollow circuit cylinder body side surface is symmetrical, be evenly provided with multiple strip hollow holes 14, arranges the hollow hole 14 of multiple strips,
Make that staving 13 weight is less, rolled steel dosage is less, the intensity of the remaining entity part of staving 13 meets all kinds of duty requirements simultaneously.In
Hollow cylinder bottom is provided with outwardly annular curtain plate 15, and curtain plate 15 is uniformly provided with connecting hole 2 16.
Connecting hole one on bottom shrouding 4（Bolt hole）5 with staving 13 on connecting hole 2 16, both hole sizes,
Position, quantity are identical, both can be fixedly connected by bolt 19.
Round pallet 10 on the internal tie of elastic cable 21, its diameter is slightly less than the internal diameter of staving 13.Elastic cable 21
With by stage clip 18, its outline diameter is slightly less than the diameter of round pallet 10 for extension spring 17；The staving 13 top board center of elastic cable 21
The preformed hole 12 at place, has a diameter larger than the diameter of pull bar 8.
One end of extension spring 17 is fixed on the earrings 2 11 of supporting plate 10 bottom of circle, and the other end is fixed on bottom shrouding one
On the earrings 1 of side；The outline diameter of extension spring 17 is slightly less than the internal diameter of staving 13, and it can be with the motion of round pallet 10
Freely up and down activity inside staving 13.
Stage clip 18 is enclosed within pull bar 8, and round pallet 10 can catch stage clip 18, hold, and round pallet 10 is put with stage clip 18
Inside staving 13, the mooring ring 7 on pull bar 8 is placed in outside by the preformed hole 12 of staving 13.The round pallet that pull bar 8 is ined succession
10 can freely up and down activity inside staving 13 with stage clip 18.
In fact, extension spring 17 is identical with the size of both extension springs 18, material parameter, simply act on drop-down in mooring forces
There is elasticity of elongation deformation in spring 17 under tension, and extension spring 18 is under pressure and elasticity of compression deformation occurs, only this difference.
Extension spring 17 and extension spring 18 are high-strength spring, and it can occur larger elastic deformation, can bear larger pulling force
With pressure.The maximum flexibility deformation length of two springs is the maximum flexibility stroke of an elastic cable 21.Diminish in pulling force
When, elastic cable 21 can be gradually brought to original length from maximum flexibility deformation length.
The mooring ring 7 at multiple elastic cable 21 two ends is connected with common anchor chain by fastener with mooring ring 1, that is, being formed can
There is the novel anchor chain system of larger elastic deformation.Common anchor chain refers to by the many anchor chains that steel chain link is connected herein.
It is assumed that the maximum flexibility deformation length of an elastic cable 21 isIf using in a mooring systemnIndividual elastic cable 21, then anchor chain
The maximum flexibility deformation that system can occur adds up.When by larger wind wave action, there is elastic deformation in anchor chainMust
So absorb, consume larger stormy waves impact energy so that net cage and the anchoring stormy waves load peak clipping that is subject to of basis diminish, stagnant
Afterwards, the security to protection net cage and anchoring basis is favourable.And traditional steel anchor chain, it can not deform, larger
Passing to net cage and anchoring basic of the direct single-candidate of stormy waves load, larger to the security threat of net cage and anchoring basis.
Elastic cable 21 occur maximum flexibility deformation length during this part stormy waves impact energy have been converted into spring
Elastic energy be stored in spring, when stormy waves is less spring gradually recover to deform, the elasticity energy of release storage, thus having
Standby power pooling feature.
Each part of elastic cable 21 is steel or irony, and each part after assembling and the intensity of weld seam should be able to undertake all kinds of
Random seas act on the mooring forces that pass over of Lower chains and without flexing and inefficacy.
Elastic cable 21 quantity needed for mooring system carries out comprehensive determination according to stormy waves size, length of chain cable, Mooring Arrangements.
Elastic cable 21 can be made into standard component, on demand a number of elastic cable 21 is connected in common anchor chain, forms tool
There is the net cage mooring system of energy dissipating effect.Especially, the integrality of mooring system should after each high sea, be checked in time, right
Destroyed elastic cable 21 is changed, and maintains validity and the security of mooring system.
Described elastic cable 21, arrangement in use can be versatile and flexible, and such as multiple elastic cables 21 mutually interconnect
Connect formation " to connect " pattern, also the connection that is parallel to each other of multiple elastic cables 21 can form " in parallel " pattern, provide enough for mooring system
Enough intensity and security.
Operationally one end connects anchoring basis 20 to the present invention, and the other end connects net cage 23.
The present invention is not limited to above-mentioned specific embodiment, according to the above, according to the ordinary technical knowledge of this area
And customary means, under the premise of without departing from the present invention above-mentioned basic fundamental thought, the present invention can also make other various ways
Equivalent modifications, replacement or change, be within the scope of the present invention.
