Description
Technical field
The present invention relates to aquatic product fishery device field, more particularly to a kind of jellyfish removers for trawlnet.
Background technology
With the continuous deterioration of global warming, seawater eutrophication and marine environment, jellyfish is worldwide
The trend broken out is formd, and increasingly severe.The breaking out of jellyfish will cause mankind's activity, society and economy extremely bad
Influence.Wherein, being broken out by jellyfish influences sea fishery most serious of all.Because jellyfish, which breaks out, has not only broken up marine food
The Nutrient Cycle of chain, and seriously hinder the fishing operation of the mankind.Being broken out by jellyfish, which influences operating type the most serious, is
Trawlnet.Because trawlnet is to pull netting gear in marine carry out operation by fishing boat, belong to active fishing gear.Reflect according to fisherman, if
Jellyfish is suffered from when trawling, it will be fisherman's " disaster ".Because jellyfish not only can block and destroy netting gear, but also meeting
Fishery output is reduced, the time that fisherman handles fishery harvesting is increased.In addition, some species of jellyfish also have toxin, the person of fisherman is pacified
There is great hidden danger entirely.In general, being engaged in the fisherman of trawling once meeting with a large amount of jellyfishes in fishing ground, can only be forced
Stop fishing operation or conversion fishing ground.In the prior art, mainly by opening liberation port or installation with rigid in trawlnet body
Property separate gate release device (such as technical solution of comparison text CN200620044481.7).The technology of body liberation port is installed
Means can cause trawl catch yield to decline.In trawlnet no using rigid separate gate release device (CN200620044481.7)
But huge water resistance is produced, the fuel consumption of fishing boat is increased, and is easy to generate netting gear blocking, to directly affect
The productivity effect of trawlnet；In addition, rigid mount, which is installed in trawlnet, to generate certain harmful effect to rising, putting net operation.

As shown in figure 3, the overlapping mesh sheet 8,10 that automatic release mouth structure is respectively arranged with liberation port by two panels is constituted, specifically
A mouth can be opened on the bottom etting of the nearly small-bore one end of conical hollow chorista 2, two overlapping sewings of mesh sheet 8,10 are existed
In the opening of above-mentioned etting, the liberation port of overlapping mesh sheet 8,10 is dislocatedly distributed.Under certain compression weight, it is overlapped mesh sheet 8,10
Liberation port can overlap, at this moment can discharge jellyfish automatically.The length of two liberation ports 9,11 is 1.5~2.5m, and width is equal
For 20-50cm, two 9,11 distances of liberation port are 45~70mm.In the present embodiment, the length of two liberation ports is 2.0m, wide
Degree is 30cm, and two liberation port distances are 60mm.
As shown in figure 4, when being caught, the nearly 2 bigbore one end of the conical hollow chorista of hollow frame 1 with drag
Net body 21 connects, and the other end of hollow frame 1 is connect with Cod-ends of Trawl 23.
Catch principle：When trawlnet encounters a large amount of jellyfishes in fishery, the body of trawlnet most back segment is detached with net capsule, so
The jellyfish remover of the present invention is sutured in wherein afterwards, you can come into operation.Catches enter hollow frame from trawlnet body 21
Conical hollow chorista 2 in frame 1, catches have certain escape capability, can be escaped into from conical hollow chorista 2
In Cod-ends of Trawl 23, jellyfish escape capability is weak, cannot again be escaped into Cod-ends of Trawl 23 after entering conical hollow chorista 2,
Therefore it is gathered in the front of conical hollow chorista 2.When the jellyfish quantity in conical hollow chorista 2 slowly increases, weight
It is consequently increased, under certain compression weight, the liberation port of two pieces of mesh sheet can overlap, and at this moment can discharge jellyfish automatically.
Different fishing grounds, different capacity size trawler used in trawlnet specification can be variant.Selected by this application example
Trawlnet body most back segment size of mesh be 50mm, net capsule circumference stretch length be 6.0m.After the body of the trawlnet as used in trawlnet
Section size of mesh and net capsule circumference, which stretch length and the present embodiment, larger difference, with reference to this application example sheepshank ratio to frame
The specification of frame and rete cord slightly adjusts.
Trawlnet body and net capsule are attached by the present invention by frame, utilize the build and again of jellyfish and other catches
Difference is measured, by the conical hollow chorista made of the different mesh sheet of several size of meshes and the suture of hollow frame bottom by water
Mother is detached with other fishery harvesting, is excluded jellyfish by automatic liberation port after the amount of fishing of jellyfish reaches a certain level, both
The effective exclusion for realizing jellyfish, in turn ensures the yield for not losing other economic fishery harvesting.In addition, the material of the present invention is all
Flexible body, will not increase the water resistance of trawling, while put net and hauling operation is also convenient for flexibly.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
