Abstract

The marine aquaculture mesh cage with ocean current resisting anchoring unit includes frame, mesh coating, mesh ribs, support, sinkers in corners of mesh coating and bottom, main anchoring cables, anchor chain and anchors, and features its bottom frame, ocean current resisting anchoring cables, which connect the bottom frame and the main anchoring cables via rotating ring, and buffering ocean current resisting anchoring sinkers set between each main anchoring cable and anchor chain. It may have rhombic or crossed support frame set inside the bottom frame. The ocean current resisting anchoring method includes assembling mesh cage frame and mesh coating, sewing the bottom mesh coating to the bottom frame movably, installing rotating rings, connecting the main anchoring cables and ocean current resisting anchoring cable to the rotating rings, mounting the buffering ocean current resisting anchoring sinkers, connecting anchor chain and anchors and finishing the mesh coating.

Description

The current resistance mooring method and apparatus of net cage for sea farming
Technical field
The present invention relates to a kind of current resistance mooring technology, is the method and apparatus of net cage for sea farming current resistance mooring specifically.
Background technology
Wind wave resistance net cage is thrown in all the year round marine, and reason such as abominable and strong ocean current is easy to cause that net cage is out of shape greatly owing to sea situation.The net cage distortion will reduce its effectively breed volume on the one hand, increase the suffered environmental pressure of fish body, influence its growth.On the other hand, the etting distortion makes the inside and outside current exchange variation of net cage, influences the water quality in the net cage, is unfavorable for the healthy fish growth, even diseases induced.The existing net cage volume of reducing the loss mainly is to adopt at fluoran stream surface the idle net cage of one row is set, to reduce the water velocity by fish culture net cage; Steel bar framework or plastic frame perhaps are installed to keep the etting bottom shape constant in the net cage frame bottom, are reduced volumetric loss as far as possible.But, idle net cage is set, will increase the cost of fish culture net cage, be generally culture the owner can not bear.And the bottom adds framework, and at flow rate of water flow hour, effect is very remarkable, but when flow velocity greatly the time, under(-)chassis will float towards the direction of current, and the whole height of net cage is diminished, thereby also will significantly reduce the dischargeable capacity of net cage.The framework that existing in addition net cage bottom is installed for reducing volumetric loss, adopts thicker bar construction more, and this bar construction causes tearing of etting extremely easily when the draping clothing, thereby shortens the service life of net cage greatly.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide, reduce the current resistance mooring method and apparatus of the net cage for sea farming of net cage volumetric loss to increase the flow-resistant capacity of net cage.
The present invention installs a bottom framework with the bottom of net cage on the basis of existing net cage technique, and a wind wave resistance current resistance mooring rope is set specially and corresponding Bower Anchor pool rope is connected to the ring of anti-the circulation at Qi Sijiao; Bracing frame can also be set in underframe.Thereby can guarantee that etting is under big water impact, because pining down of wind wave resistance current resistance mooring rope, the net cage under(-)chassis is towards almost not drift of water (flow) direction, distortion only occurs over just on the etting of front and back, and the modified difference of front and back etting seldom can be cancelled out each other, and then the volumetric loss of whole net cage is almost nil, simultaneously because the use of wind wave resistance current resistance mooring rope, to reduce the required heavy power of net cage greatly, thereby the specification of under(-)chassis and required heavy power are diminished, reduced the possibility that etting is torn.In addition, the present invention adopts when under(-)chassis is installed and flexibly connects, and equally also can reduce etting and tear.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present invention.
1. underframes wherein, 2. bracing frame, 3. change, 4. framework, 5. etting, 6. net muscle, 7. support, 8. current resistance mooring rope, 9. current resistance mooring sinker, 10. Bower Anchor pool rope, 11. anchor chains, 12. anchors, 13. sinkers.
Embodiment
As Fig. 1, the present invention includes framework 4 and go up the etting of installing 5 and net muscle 6, support 7, and the sinker 13 on four jiaos of etting and the bottoms, with Bower Anchor pool rope 10 and anchor chain 11 and anchor 12, it is characterized in that it also comprises underframe 1 and connects current resistance mooring rope 8 between underframe 1 four bights and the Bower Anchor pool rope 10, and current resistance mooring rope 8 and Bower Anchor pool rope 10 be connected to change 3, and moor between rope 10 and the anchor chain 11 at Bower Anchor double buffering wind wave resistance current resistance mooring sinker 9 is arranged.The above-mentioned position that is arranged on change 3 on the Bower Anchor pool rope 10 is 4 times of net cage height normally, (rope 10 upper extreme points that independently anchor are counted).Consider further to reinforce the intensity of underframe, reduce the distortion of underframe, in above-mentioned underframe 1, a bracing frame 2 can be set.Above-mentioned bracing frame 2 is cross or the diamond structure bodies in underframe 1, the current resistance mooring method of net cage for sea farming is after etting 5 and support 7 are installed on the framework 4, the bracing frame 2 usefulness net muscle 6 of underframe 1 and interior welding thereof are highly linked together framework 4 and underframe 1 according to the etting assembling, after treating that etting 5 and framework 4 assemble, adopt loose joining that net cage bottom etting is sewn on the underframe 1, change 3 is installed at the place at 4 times of net cage height of distance Bower Anchor pool rope 10 upper extreme points (A), the long current resistance mooring rope 8 of intercepting for 3.8 times of net cage height, and Bower Anchor moored rope 10 and current resistance mooring rope 8 is connected in the change 3, double buffering wind wave resistance current resistance mooring sinker 9 is installed on the Bower Anchor pool rope 10, and connect anchor chain 11 and anchor 12, put etting at last in order and get final product.
The present invention makes etting significantly reduce with the drift of current, makes the almost not loss of effective water body volume of net cage, has increased the fish culture net cage flow-resistant capacity.In addition, owing to adopted the loose joining connection between etting 5 and the underframe 1, when hauling, can earlier etting be separated from underframe, play etting earlier, then play underframe, this will reduce the possibility that etting is torn greatly, increase the life-span that net cage uses greatly.
