Abstract
The utility model relates to a cololabis saira stick-held net structure, which is mainly used for trapping cololabis saira. The cololabis saira stick-held net structure structurally comprises a main netting and a floater, wherein the upper edge of the main netting is connected with an upper edge rope through an upper edge netting, the lower edge of the main netting is connected with a lower edge rope through a lower edge netting, the side surface of the main netting is connected with a side edge rope through a side edge netting, the floater is installed on the upper edge rope, and the mesh of the upper edge netting, the lower edge netting and the side edge netting is greater than that of the main netting. The main netting is connected with the rope through each side edge netting, so that the tension on two ends of the main netting can be buffered, the friction between the edge of the netting and the rope can be reduced, and the overall strength of the netting can be improved. The mesh of each edge netting is greater than that of the main netting, so that the strength of the main netting can be enhanced, the fracture of the netting can be prevented from being enlarged, the service life is prolonged, and the cololabis saira stick-held net structure is suitable for the fishing of long-distance fishing boats.
Description
Technical field
The utility model relates to a kind of saury stick held net structure, is mainly used in the collection that lures of saury.
Background technology
The saury stick held net is a kind of mode of saury fishing operation, and the stick held net shape is generally square or rectangle.During use, net is laid in the water in advance, utilizes the phototaxis of saury, fishing lamp is installed on fishing boat is used for luring the fish gathering crowd, fish for stick held net then.
Existing stick held net is owing to be that offshore is fished for; Its structure just simply reaches each the edge rete cord that links to each other with etting by float, etting to be formed, and the ship type that is used is less, has only 10t-100t usually; Absorb water more shallow; No matter be netting gear size, the configuration of fishing lamp quantity, all than little many of long range fishing fishing boat, the technology of fishing for is also simple relatively for scale.But for China, the saury resource is the high sea resource, belongs to long range fishing; Fishing boat is also mostly to be more than the 1000t, and the etting and the etting of existing stick held net structure are connected simply with each rete cord junction, edge, and intensity is relatively poor; Very easily damage, be not suitable for the long range fishing fishing boat and use.Therefore existingly be used for the requirement that stick held net that the offshore saury fishes for also can not satisfy China's long range fishing fishing boat far away.
Summary of the invention
The utility model technical problem to be solved is to overcome the saury stick held net insufficient strength that exists in the above-mentioned prior art; Be inappropriate for defectives such as long range fishing; And a kind of saury stick held net structure is provided, this stick held net structural strength is big, is suitable for the long range fishing fishing boat and uses.
For solving the problems of the technologies described above, the utility model technical scheme is achieved in that a kind of saury stick held net structure; Comprise major network clothing and float; It is characterized in that: the top edge of said major network clothing links to each other with the upper limb rete cord through last selvedge, and selvedge linked to each other with the lower edge rete cord under lower limb passed through, and the side of major network clothing links to each other with the lateral margin rete cord through the lateral margin etting; Said float is installed on the upper limb rete cord, saidly goes up selvedge, selvedge, lateral margin etting are bigger than the mesh of major network clothing down.
It is said that upward selvedge is littler than following selvedge mesh with the mesh of lateral margin etting.
Said major network clothing, last selvedge, following selvedge, lateral margin etting link into an integrated entity and form the trapezoid structure.
Said major network clothing size of mesh scope is between the 18.9-25.76mm.
Saidly between the adjacent side lip rete cord, be provided with a plurality of sides and draw together rete cord.
Be connected with sinker on the said lower edge rete cord.
The beneficial effect of the utility model: the utility model major network clothing is through last selvedge, down selvedge, rete cord that the lateral margin etting is corresponding with each link to each other, and buffering major network clothing two ends tension force reduces the friction of etting edge and rete cord, thus the bulk strength of increase etting.The mesh of each edge etting is bigger than major network clothing, strengthens major network clothing intensity, prevents etting expansions of breaking, and raising service life, is particularly suitable for fishing for of ocean fishing vessel.
Utilize the phototaxis of saury class, the effect increase cluster scale through fishing lamp strengthens the effect that lures the fish gathering crowd thereby reach.Its structure is convenient and simple, cost is low.Can effectively increase the cluster scale of fish.Thereby make the output of saury purse seine and catching rate be able to improve significantly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as shown in Figure 1.A kind of saury stick held net of the utility model structure comprises major network clothing 1, float 2, sinker 3, last selvedge 4, following selvedge 5, lateral margin etting 6, upper limb rete cord 7, lower edge rete cord 8, lateral margin rete cord 9.
Said major network clothing 1 is that several rectangle net sheets are formed, conveniently to roll and seam is torn open.Netting twine adopts polyamide fibre, can make etting sedimentation and hoisting rapidly, and the mesh optimum size scope of said major network clothing 1 is 18.9-25.76mm.The top edge of said major network clothing 1 is installed on the upper limb rete cord 7 through last selvedge 4, and lower limb is installed on the lower edge rete cord 8 through following selvedge 5, in order to strengthen the intensity of major network clothing at last lower limb, cushions the effect of external current to major network clothing 1.The side of major network clothing 1 is installed on the lateral margin rete cord 9 through lateral margin etting 6, bears vertical tension force.Said major network clothing 1, go up selvedge 4, selvedge 5, lateral margin etting 6 link into an integrated entity and form the trapezoid structure down, as the netting gear that lures the collection saury.Last selvedge 4, selvedge 5, lateral margin etting 6 can cushion major network clothing 1 two ends tension force down, reduce the friction of major network clothing 1 edge and rete cord, the bulk strength of increase netting gear.
Saidly go up selvedge 4, selvedge 5, lateral margin etting 6 are bigger than the mesh of major network clothing 1 down, use thicker netting twine, and on selvedge 4 littler with the mesh of lateral margin etting 6 than following selvedge 5 meshes, can further increase the intensity of netting gear.
Said sinker 3 is connected on the lower edge rete cord 8, can keep the net shape of etting in water, make its not reason receive current and produce than high camber; Volume is fished in loss; Can be when guaranteeing net form, make that etting sinks rapidly when putting net, put net efficient thereby improve.
Saidly between the adjacent side lip rete cord, be provided with a plurality of sides and draw together rete cord.Be convenient to hauling and receive when twisting, etting is " pocket " shape, closes up the shoal of fish.
Said float 2 links to each other with upper limb rete cord 7, and said float 2 links to each other with ship side through the float lifting rope, has certain-length, generally is chosen as 30-50m, and the existence of float 2 makes under various sea conditions, can accurately control puts the net distance.Because high sea, ocean stormy waves is bigger, float 2 can make etting can float on the sea always, simultaneously by float 2, etting is fixed, and it is convenient to receive the hoisting net clothing, also avoids etting to twine.
The description of above-mentioned embodiment is the concrete embodiment of the utility model, but can not limit the protection domain of the utility model with this, and variation and the modification done in this way in every case are all within the protection domain of the utility model.
