Description
Technical field
The utility model provides a kind of wind and wave resistance double net wall hermetic type net cages, belongs to aquaculture net cage field.
Background technology
Applied to aquaculture field, be particularly suitable for use in marine cage culture, or big water body, the net in such as reservoir, lake
Cage breeding is grown.Higher swim fish, such as Atlantic salmon, madai, grouper, rock porgy, rainbow trout are worth available for culturing economic
Etc. kind.
Marine cage culture this year is flourished, and numerous national, provincial level projects are made greater efforts to promote the hair of marine cage culture
Exhibition, especially offshore cage culture, i.e. develop into offshore farther out, waters is open, depth of water depth reaches, and water body exchanges sufficient water
Domain carries out the cage culture of fish.This kind of waters is relative to nearshore waters, and water stabilization, water body capacity is big, and water coke slurry is sufficient, no
Easily cause the residual bait in water body and substrate, excrement to accumulate in breeding process, can avoid causing water pollution.But the water body area
Domain, stormy waves is larger, and stormy waves generation is more frequent therefore higher to the wind and wave resistance performance requirement of aquaculture net cage.
Traditional wind wave-resisting net casing, is generally single etting structure, i.e., dangle individual layer etting, individual layer etting one around net cage frame
Denier is damaged, and easily causes escaping for cultured fishes, if cultivation is non-local species, it is likely that cause biotic intrusion, long-range next
See, consequence is difficult to estimate.Meanwhile, cultured fishes are escaped, and can directly contribute economic loss.The damage of etting, it is also possible to cause
The outer fish of net cage enter net cage, predation activity are carried out to cultivation object, or parasite and disease infectious disease are cultivated in net cage
Fish, cause the economic loss in breeding process.
Traditional net cage, because it is furnished with individual layer etting, and etting material is generally polyethylene (PE) material, and etting pendency exists
After in water body, etting shape is difficult to keep, when stormy waves is larger, and the area change in corral area of etting institute acutely, influences cultivation pair
As activity, such as extruding culturing area causes fish crowded, causes external injury, even results in dead generation.Or surrounding and bottom
Etting is moved up under the promotion of current, is forced fish to be swum to water body top layer, is then easily caused fish to escape.
Traditional net cage, hardly equipped with making flow device.When in reservoir or lake environment, without larger stormy waves, water
Bulk wave moves small, and water body exchange capacity is poor, disposes water body in large-scale net cage, net cage actively to be handed over extraneous water body in such environment
Transducing power is poor, and a large amount of fish of cultivation carry out respiration in net cage, easily causes in net cage that water body dissolved oxygen is relatively low, causes water
Body anoxic.Meanwhile, after feed is fed to cultured fishes, residual bait, excrement are easily accumulated among the sediment below off the net,
Cause substrate eutrophication, so as to influence overall water environment.
Utility model content
The utility model purpose is to provide a kind of wind and wave resistance double net wall hermetic type net cages, can be prevented effectively from larger stormy waves and lead
Fish injury in net cage is caused, net cage situation damaged in high sea is effectively prevent, water body exchange capacity is strong.
Hung with the double net wall hermetic type net cages of wind and wave resistance described in the utility model, including net cage frame, net cage frame foster
Grow and be uniformly connected with linking arm on net, net cage frame, linking arm, which is hung oneself, outer layer culturing net and internal layer culturing net, internal layer culturing net
It is placed in outer layer culturing net, supply equipment is installed on net cage frame, supply equipment is provided with lift pump, and the drinking-water pipe of lift pump is stretched
Enter in the seawater outside net cage, the delivery port of lift pump is connected with water inlet pipe, and water inlet pipe is stretched into net cage, water inlet pipe is provided with water outlet
Mouthful, delivery port and the net cage frame tangent line of its relevant position are connected with 30 degree of angles, outer layer culturing net and internal layer cultivation sieve bottom
Sewage collection system.
The double net wall hermetic type net cages of described wind and wave resistance, internal layer culturing net is high density polyethylene (HDPE) etting.
The double net wall hermetic type net cages of described wind and wave resistance, outer layer culturing net is canvas type etting.
Oxygen supply unit is set on the double net wall hermetic type net cages of described wind and wave resistance, net cage, oxygen supply unit includes aerator, supplies
The oxygen exhaust of oxygen machine is connected to water inlet pipe, and oxygen supply unit constitutes water supply oxygen supply unit with supply equipment.
The utility model has the beneficial effect that compared with prior art：
The double net wall hermetic type net cages of described wind and wave resistance, outer layer culturing net uses the harder canvas of material as material, outside
Layer canvas type etting weight is big, after being immersed in the water, and attitude stabilization is not easy to deformation under flow action, is also hung for internal layer
Internal layer culturing net provides Additional Protection.It will keep apart simultaneously inside and outside net cage, first, prevent the fish of cultivation in net cage from escaping into
Enter natural water.Second, prevent the fish outside net cage from carrying the pathogen such as parasite and enter net cage, infect cultured fishes, simultaneously
It can prevent outside fish from entering net cage and preying on cultured fishes.Water supply oxygen supply unit sets many places on net cage frame, due to thereon
Delivery port be multiple and positioned at different water depth, with delivery port of the tangent line in 30 degree of angles, the water of ejection can manufacture rotation in net cage
Turn current, while the water outside net cage is pumped into net cage, enhance water coke slurry ability, make in net cage water velocity from net cage edge
To the uniform distribution of successively decreasing in net cage center, it is adapted to cultured fishes and selects suitable flow rate environments to be moved about.Meanwhile, rotary water current can
It is collected with the sewage sump for the bottom that the residual bait produced during cultivation, excrement are pushed to net cage center.Such current stream
Flowing mode additionally aids dissolved oxygen being uniformly distributed in net cage interior zone.Uniform change in flow and dissolved oxygen distribution contribute to cultivation
The growth of fish, while the cultivation density of unit of water body can be improved, improves overall productivity.
