Abstract
The utility model relates to a superficial drawn net whose net bodies are in taper shape. Columnar cod ends are arranged under the net bodies. The upper part of the upper net body is connected to the sleeve net. The upper par of the lower net body connects with the sleeve net through a belly net. The lower net mouth is longer than the upper net mouth. The superficial drawn net has the advantages of convenience in releasing and retracting the net, short time, large trawling amount, low labor intensity, low usage cost and low loss of the nets. The utility model is suitable to be used to trawl the fishes in the middle and upper layer water areas.
Description
The utility model relates to fishing net, particularly a kind of be applicable to fish in, the surface trawl of superjacent waters Mesichthyes.
As everyone knows, in existing the fishing for, the netting gear of superjacent waters Mesichthyes is the single net sheet of rectangle, net sheet top is provided with the head rope, it is cursory to which is provided with, and net sheet below is provided with down the head rope, which is provided with the drift net of sinker, during fishing operation, the net sheet is banded and floats with stream perpendicular in the water, and fish are initiatively run on the net.The mode of fishing for of this netting gear is a passive type, and amount of fishing is little, and netting gear is longer, and the net trouble is put, received to the use cost height, and the time is long, and labour intensity is big, and netting gear floats with ocean current and also very easily loses.Existing trawlnet is the bottom trawlnet, be link respectively by two bush ropes about each two empty guiding principle, each two dovetail net about empty guiding principle links respectively, the net of tucking inside the sleeve about dovetail side off the net links respectively, body is upper coarse and lower fine taper shape, the below links keed, last slice body top is tucked inside the sleeve online about the overline bridge net is attached at, following sheet body top directly is attached on the wing of the left and right sides, the following network interface of following sheet body is provided with down the head rope, which is provided with sinker, and the last network interface of last slice body is provided with the head rope, it is cursory to which is provided with, and the following head rope to afterbody is provided with two manropes.This netting gear can not escape the fish in the bottom waters from last network interface because last slice body has had more the overline bridge net, and following sheet body lacks belly, and last network interface is longer than down network interface, therefore only is applicable to the fish of fishing in the subjacent waters.
The purpose of this utility model provides that a kind of to put, receive net convenient, and the time is short, and amount of fishing is big, and labour intensity is low, and use cost is low, and netting gear is difficult for the surface trawl of loss.
For achieving the above object, feature of the present utility model is, body 8 is upper coarse and lower fine taper shape, and its below is provided with cylindrical keed 9, and last slice body 8 tops are attached on the sleeve net 4, and following sheet body 8 tops are connected through belly 7 and sleeve net 4, and following network interface is longer than network interface.
The utility model can adopt the synthetic polyethylene cotton rope of multiply monofilament of different size to be made into each several part net sheet, after typing is handled, be woven into upper coarse and lower fine body 8, the cylindrical keed 9 of its below braiding, last slice body 8 is woven on the sleeve net 4, and following sheet body 8 braiding bellies 7 are on the net 4 of tucking inside the sleeve about belly 7 is woven in, make down the sheet network interface be longer than a network interface, fish are difficult for escaping from the network interface below.About sleeve net 4 tops respectively weave two dovetail nets 3.Set down the head rope 12 on the following network interface, the following head rope 12 adopts steel wire rope to make, and which is provided with the sinker 11 that iron chains, lead or rubber roll are made.Set the head rope 5 on the last network interface, the last head rope 5 adopts steel wire rope to make, and bolt bundle cursory 6 on it.The following head rope 12 is provided with manrope 10 to keed 9 external diameters, and manrope 10 can adopt steel wire rope to make.The last head rope 5 and two ends, the following head rope 12 left and right sides respectively with about each two empty guiding principles 2 be connected, the empty guiding principle 2 of the right and left respectively with about two bush ropes 1 be connected.When putting net, bush rope 1 is wound on the cylinder of winch, surface trawl is pushed in the seawater in proper order by putting the net boat afterbody, and successively bush rope 1 is emitted, reach need length after, the band net boat is drawn close to putting net boat, and band net boat traction is a bush rope wherein, and two ships are sailed out, reach apart require after, two ships are with parallel the advancing of speed, and the traction surface trawl advances, and the fish of superjacent waters are entered in the surface trawl.During hauling, two fishing boats are drawn close, the band net boat is given bush rope 1 and is put net boat, putting net boat hangs over it on cylinder of winch, article two, bush rope 1 is hoisted by winch together, treat that dovetail net 3, sleeve net 4 strand are gone into fishing boat after, surface trawl is hung on the ship by joint by suspension rod again, untie keed 9 rope ligatures, catches is poured out.
It is convenient that net is put, received to the utility model, and the time is short, and amount of fishing is big, and labour intensity is low, and use cost is low, and netting gear is difficult for loss, is applicable to the fish in fishing for, in the superjacent waters.
Description of drawings
Accompanying drawing is a kind of schematic diagram of the present utility model, also is the schematic diagram of a kind of embodiment.
Mark in the accompanying drawing is: bush rope 1, empty guiding principle 2, dovetail net 3, sleeve net 4, go up the head rope 5, cursory 6, belly 7, body 8, keed 9, manrope 10, sinker 11, the head rope 12 down.
Embodiment: surface trawl as shown in the figure, adopt the synthetic polyethylene cotton rope of multiply monofilament of different size to be made into each several part net sheet, after typing is handled, be woven into upper coarse and lower fine body 8, the cylindrical keed 9 of its below braiding, last slice body 8 is woven on the sleeve net 4, following sheet body 8 braiding bellies 7, on the sleeve net 4, make down the sheet network interface be longer than a network interface about belly 7 is woven in, fish are difficult for escaping from the network interface below.About sleeve net 4 tops respectively weave two dovetail nets 3.Set down the head rope 12 on the following network interface, the following head rope 12 adopts steel wire rope to make, and which is provided with the sinker 11 that iron chains is made.Set the head rope 5 on the last network interface, the last head rope 5 adopts steel wire rope to make, and bolt bundle cursory 6 on it.The following head rope 12 is provided with manrope 10 to keed 9 external diameters, and manrope 10 adopts steel wire rope to make.The last head rope 5 and two ends, the following head rope 12 left and right sides respectively with about each two empty guiding principles 2 be connected, the empty guiding principle 2 of the right and left respectively with about two bush ropes 1 be connected.When putting net, bush rope 1 is wound on the cylinder of winch, surface trawl is pushed in the seawater in proper order by putting the net boat afterbody, and successively bush rope 1 is emitted, reach need length after, the band net boat is drawn close to putting net boat, and band net boat traction is a bush rope wherein, and two ships are sailed out, reach apart require after, two ships are with parallel the advancing of speed, and the traction surface trawl advances, and the fish of superjacent waters are entered in the surface trawl.During hauling, two fishing boats are drawn close, the band net boat is given bush rope 1 and is put net boat, putting net boat hangs over it on cylinder of winch, article two, bush rope 1 is hoisted by winch together, treat that dovetail net 3, sleeve net 4 strand are gone into fishing boat after, surface trawl is hung on the ship by joint by suspension rod again, untie keed 9 rope ligatures, catches is poured out.
