To between pull bar 6.Further reinforcement structure stability and reliability.
Further, the vertical framework includes：Annular pull rod；It is perpendicular with described that the annular pull rod is fixed on the strut
To the junction of pull bar.So as to provide horizontal tightening structure, lift structure intensity.Keep the stability of vertical pull bar.
The present embodiment provides the working condition of box mainly to be included：
The first, is that all ballast tanks do not add water, and net cage can float on the surface, and now, net cage under(-)chassiss just submerge
In water, drinking water 2m or so, at this moment net cage center of gravity is higher than centre of buoyancy, and gravity is equal to buoyancy；
Second, be all ballast tank topped up with water, and net cage major part can be immersed in the water, and net cage ring float major part is submerged
In water, drinking water 8m or so, at this moment net cage centre of buoyancy is higher than center of gravity, and gravity is equal to buoyancy；
The third, on the basis of second, is added downwards certain power to net cage, is realized by tension force anchoring system,
Net cage drinking water is allowed to increase to 10m work drinking water states, ring float does not have 2m below upstream face, and at this moment net cage centre of buoyancy is higher than center of gravity,
Gravity is less than buoyancy, and small-waterplane-area drinking water state, capacity of anti-storm are lifted.
4th kind, violent typhoon comes interim, on the basis of the third, increases the downward additional force of net cage, by tension force system
Pool system realizes that allow net cage to be totally submerged in water, at this moment net cage centre of buoyancy is higher than center of gravity, and gravity is less than buoyancy, it is to avoid violent typhoon
Impact to net cage.
In the embodiment of the present application, the vertical framework of the cylinder net cage formed by pole structure, a diameter of 40m are high
Degree is about 13m, and transverse frame is highly 7m, and work drinking water 10m, effectively cultivation about 1.2 ten thousand stere of volume.In work drinking water shape
State, centre of buoyancy are more than gravity 10% to 15% higher than center of gravity, buoyancy, and extra buoyancy is shared by the pulling force of mooring cable.
Technical scheme in above-mentioned the embodiment of the present application, at least has the following technical effect that or advantage：
Ring float provides part as main buoyancy, by the reasonable arrangement of version, makes pole structure main
Tension is born, the strength and stiffness problems of longspan structure are efficiently solved, cage structure weight is alleviated, is improve flat
The performance of platform.Far-reaching extra large aquaculture net cage uses tension mooring system, is partially surfaced condition, improves capacity of anti-storm during work；When
When high sea is to attack, whole net cage ballast can be sunk down into below the water surface, it is to avoid stormy waves causes to damage to net cage, it is ensured that cultivation
Job safety reliability.Design simultaneously makes the centre of buoyancy of net cage higher than center of gravity, and platform is in stability, when net cage is inclined,
A torque can be produced between gravity and buoyancy makes net cage reply original poised state.
The Cultivated water of far-reaching extra large aquaculture net cage is most deep up to 300m, expands significantly the operation waters of fishery cultivating.Net
Clothing can be fixed on rigidity supporting structure, and Cultivated water flow rate of water flow is on effectively cultivation volume without impact.
One or more technical schemes provided in the embodiment of the present application, at least have the following technical effect that or advantage：
The far-reaching extra large aquaculture net cage provided in the embodiment of the present application, by center stand column, barrel-shaped framework and pole structure
A cage structure is surrounded, reliable and stable mechanical structure is formed, is realized large span, the frame structure of high intensity；Using frame
Support fixed structure of the rigid structure of frame as fishing net piece, keeps the deployed condition of fishing net piece, reliable and stable, solves water flow velocity
Impact to effectively cultivation volume；By ballast cabin structure, immersed depth is adjusted, gravity is more than when making aquaculture net cage work drinking water
Buoyancy, is seated seabed, without the need for anchoring, possess anti-typhoon capacity, also can floating displacement hide Super Typhoon, substantially reduce cultivation
Risk.On the other hand, during work, by adjusting the loading water yield of ballast tank, the centre of buoyancy of net cage is higher than center of gravity, so that net cage
Attitude possess fabulous stability, when net cage be hit inclination when, can produce a torque between gravity and buoyancy makes net cage
Recover original poised state.
