Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to chain-type drifts along case net.
Background technique
Cage culture is the pith of marine economy, is had a vast market and development potentiality.Cage culture process without
Auxiliary resources is needed, it is resource-effective, have the characteristics that Low investment high repayment.The key factor for restricting deep-sea breeding is the anti-of net cage
Stormy waves ability solves the problems, such as that this will set out to entire industry to deep water and increases power-assisted.
Cage culture faces the threat of stormy waves in ocean, such as the net cage that can will even float on sea under the conditions of typhoon
It destroys, can largely improve this defect there are two approach.First is that realizing drifting along for net cage, certainly due to Wave energy
The water surface is gradually reduced to seabed, and net cage, which is sunk, can effectively antagonize stormy waves；Second is that original rigid structure is changed to flexibility
Structure is defeated a force with a tenderness to reduce and destroy.
Summary of the invention
It drifts along case net the purpose of the present invention is to provide chain-type, is gone to net cage under sea by the drive of flexible chain
For higher depth to resist stormy waves, the interior design of net cage can effectively accelerate the exchange velocity of inside and outside water flow, can also be same to a variety of fishes
When cultivate, improve the culture efficiency of fisherman.
The scheme that the present invention is taken to achieve the above object are as follows: chain-type drifts along case net, including float, roller double-strand
Item, frame, lower portion are equipped with the outer cultivation string bag, and the connected roller chain in the quadrangle of frame, roller chain end connects
Anchoring block is connect, roller chain top connects float by connection frame.Four right-angle sides and roller chain of the outer cultivation string bag
Item is fixedly connected, and when whole net cage needs to sink to the water surface or less, the winding roll at the top of the string bag will be connected to roller chain
Four extension ropes slowly wind, so that the action length of four roller chains is shortened, to keep entire net cage integrally downward
Mobile, to achieve the purpose that resist stormy waves, insertion anchor point in anchoring block bottom plays the role of fixed cage, and anchoring block upper end opens up
There is through-hole, worn in through-hole and be connected to roller chain, fixed function on the one hand can be played to chain, on the other hand can effectively be mentioned
Flexibility of the chain in running is risen, chain is avoided Caton phenomenon, the internal structure design energy of net cage occur when pulling, winding
The aquatic products of multi items is cultivated, different culturing areas is selected according to different aquatic products sizes, habit, solves existing cultivation
The also significant economic benefit for improving cultivation outside the problem of net cage cannot cultivate a variety of aquatic products.
Preferably, being arranged with pulley on the connection frame of float lower end connection, roller chain is hung on pulley, is rolled
The connection of formula chain extends rope one end, extends the rope other end and connects winding roll, winding roll is located at the top of the outer cultivation string bag.Even
Connect the pulley being arranged on frame, chain can roll on pulley, need to tighten extend rope when, by winding roll to a direction
Rotation slowly rotation, the chain for being connected to extension rope can be pulled therewith to be packed up, and entire net cage, which also will be slow, sinks down into the water surface
Hereinafter, the depth sunk can be controlled by extending rope,
Preferably, float side connects hawser one end, the other end of hawser is connected from mooring ballast.Four floats at the top of net cage
It is all connected by hawser from mooring ballast, can further improve the stability of net cage in water, prevent stormy waves weather to net cage
It influences.
Preferably, outer culturing net is revealed all the details, portion edge is connected with support plate, and support plate outboard end connects motor, motor
Output axis connection shaft, shaft surface be equipped with hairbrush.The long-term submerged in the water cultivation of net cage, especially etting bottom connects with the bottom
The precipitating of touching or bait excreta cooperating microorganisms or can have algal adhesion growth on etting, influence water body inside and outside net cage and circulate,
The outer net portion of revealing all the details is equipped with shaft, and shaft surface is equipped with hairbrush, and starting motor when needing to clean etting bottom surface, (motor is anti-water power
Machine), the output shaft of motor drives shaft, and the hairbrush on shaft surface can carry out rotary cleaning to etting bottom, can will be most
Dirt removal, dirt can flow away with the flow direction of water flow, the shaft, motor can be revealed all the details according to outer culturing net face area it is big
It is small to be arranged accordingly.
Preferably, being equipped with middle layer inside the cultivation string bag outside cultivates the string bag, middle layer, which cultivates, is equipped with interior culturing net inside the string bag
Pocket, the outer cultivation string bag, the middle layer cultivation string bag, the interior cultivation string bag mesh size ratio be 1:0.53:0.25, and 3 string bag bottom surfaces
Equipped with symmetrical cross.The string bag is divided into the outer string bag, the middle string bag, the interior string bag, can be according to the kind, size, life habit of aquatic products
Deng selecting the different string bag to cultivate different types of aquatic products, solve the problems, such as that traditional net cage can not increase breed variety, may be used also
Culture efficiency is improved now, and the mesh of the string bag in the range, has further expanded the type of aquatic.
Preferably, cross surface is equipped with annulus, cross bottom is connected with inserted link, and inserted link is plugged in bearing, axis
It holds and is installed on culturing net and reveals all the details portion.The culturing net portion of revealing all the details is provided with cross, the annulus of ten rack surfaces for cultivation aquatic products
It inhabites, shuttle, increase the activity of aquatic, aquatic is avoided to be deposited in the corner of the string bag for a long time, in the work of water flow
Also it can be accelerated the flowing of water body in etting around bearing autorotation with lower cross, avoid the deposition of bait in etting, excrement,
Make breeding environment closer to naturally, being conducive to aquatic products growth.
Preferably, cultivating the string bag, the middle layer cultivation string bag, the interior side wall for cultivating the string bag outside is connected with cast feeder, cast feeder
Top is connected with feed pipe.The setting can first be stored bait to bait thrower by feed pipe, and be set in each string bag
There is cast feeder, convenient for carrying out feedstuff feeding to the aquatic products in the string bag, bait feeding is unevenly caused when avoiding artificial feeding
The non-uniform phenomenon of aquatic products growth individual occurs.
Compared with prior art, the invention has the benefit that the design is from mooring system to net cage ontology, big portion
Divide and use flexible body, by the rotation of roller chain, in the case where there is stormy waves weather condition, net cage is gone to relatively deep under sea
Place, the culturing net portion of revealing all the details are provided with cross, and the annulus of ten rack surfaces inhabites for the aquatic products of cultivation, shuttles, increases feeding
The activity for growing aquatic products, cross can also accelerate the flowing of water body in etting, keep away around bearing autorotation under the action of water flow
The deposition for exempting from bait in etting, excrement makes breeding environment closer to naturally, being conducive to aquatic products growth, and outer culturing net is revealed all the details
The hairbrush in portion can flow away most dirt removals, dirt with the flow direction of water flow.
The chain-type provided present invention employs above-mentioned technical proposal drifts along case net, compensates for the deficiencies in the prior art, if
Meter is rationally, easy to operate.
