Abstract
The utility model provides a net bag fish outlet structure of a trawl net, in particular to a net bag fish outlet structure which is high in strength and capable of preventing small target fishes from leaking out. The net bag fish outlet structure of the trawl net comprises a net bag, a bag bottom line and a net bag force line, wherein the bag bottom line is manufactured into a rope ring through three coiler ropes with the diameter of 22 mm, is arranged at the bottom of the net bag and is connected with the net bag force line. The net bag fish outlet structure of the trawl net is characterized in that the net bottom line is provided with a buckle manufactured through a rope with diameter of 10 mm, and netting and a net screen at the bottom of the net bag are both tied on the buckle in an equant mode. a rope with the diameter of 10 mm penetrates the buckle to serve as a net bag locking line, cylindrical netting is sewed in the position of 0.5 m away from the bottom edge of the inner side of the net bag, the lower portion of the cylindrical netting penetrates the bag bottom line and is exposed out of net bag, a closed net screen with every two screen holes combined into one screen hole is arranged on the net screen at the edge of the lower portion of the cylindrical netting, the closed net screen is made of a net line with the diameter of 4 mm, and a rope with the diameter of 6 mm penetrates the closed net screen to serve as a typing rope.
Description
Technical field
The utility model relates to the fishery Cod-ends of Trawl.
Background technology
The net capsule of trawlnet is loaded on the afterbody of trawlnet, is last fish gathering place, and its effect is mainly that the storage collection enters the catches of trawlnet from the trawlnet mouth when trawling, and its end is fish outlet, is used for pouring out catches during hauling.Therefore, the net capsule will have enough intensity, weight and the impact of catches itself when sustaining maximum load, and easy to operate when satisfying hauling again.The net capsule of trawlnet is stitched into the cylinder bag shape with the sheet doubling of a slice rectangle net or by four rectangle net sheets usually.A keed fish outlet is arranged in the bottom of net capsule, be used for tightening the net capsule when trawlnet, prevent that the catches that enter the net capsule from escaping out.During hauling, hang on the fishing boat deck concentrating on catches in keed, untie fish outlet, the catches in keed are all poured out.The frame mode of the fish outlet of the net capsule of trawlnet generally has two kinds, a kind of is to wear a polyethylene rope that summary is thick in the net keed clothing at fish outlet place, tighten up rope during trawling and tie a knot to close fish outlet, though this kind structure is simple, but in the time of can only being used for the hauling such as small-sized trawlnet or shrimp trawlnet, catches are less, stressed less trawler during hauling can not be used for net produces that fishery harvesting is more, hauling weight is large, high-power fishing boat.And the net capsule of this kind structure requires the sediment in operation fishing ground more soft smooth, otherwise net capsule bottom is easy to breakage and escapes fish.Closing in place of fish outlet also often leaves because of reasons in structure the duck eye of escaping fish.Another kind is the seabed coil structures, this kind structure is the folder palm fibre guiding principle at a diameter 20mm of fish outlet assembling, and be connected with net capsule manrope, to guarantee that the net capsule has certain intensity, at present, in China, large-scale trawler all uses the net capsule of this kind structure, but the net capsule of this structure also leaves duck eye and causes the precision target catches escape or spill after fish outlet blocks.
Summary of the invention
What the utility model need to solve is the structure of a kind of net capsule fish outlet of design, when making the net capsule have higher intensity, reduces spilling of precision target catches.
the technical solution of the utility model adopts the net capsule, cod line and net capsule manrope, cod line is made fake with three strands of folder coir ropes of diameter 22mm, cod line is contained in the bottom of net capsule and is connected with net capsule manrope, play reinforcing mat capsule bottom margin etting, it is characterized in that having on cod line the flower that diameter 10mm rope is rolled to buckle, the rope of rolling flower button reserves one section lax length after passing one of cod line, reserve one section lax Length Ratio flower button between distance 70mm, roll the rope of flower button along cod line interval 150mm, continue again and reserve again one section lax length after rope is passed one of cod line, until the fake of cod line is completed the Bu Zha of flower button, the bottom equal decile of etting mesh of net capsule is tied in flower and buckles, penetrate flower with a diameter 10mm rope and buckle as net capsule lock guiding principle, net capsule lock guiding principle one end lies on cod line, takes out tight net capsule lock guiding principle and can pin fish outlet, 0.5 meter sew up a cylindrical shape etting in net capsule inboard far from the base, the cylindrical shape etting adopts the mesh same circumference identical with the net capsule, highly the net sheet of 1 meter is made, cylindrical shape etting bottom is passed cod line and is exposed outside the net capsule, make two orders and purpose receipts order mesh with diameter 4mm netting twine on cylindrical shape etting lower edge mesh, pass a diameter 6mm rope as tying rope in receiving the order mesh.
The utility model has the advantages that the net capsule has higher intensity, fish outlet has 2 roads to block, and after net capsule fish outlet blocks, greatly reduces spilling of precision target catches.
Description of drawings
Fig. 1 is the schematic diagram that net capsule bottom installs the cylinder etting additional.
Embodiment
The utility model (referring to accompanying drawing) adopts net capsule, cod line 2 and net capsule manrope 1, cod line is that (the folder coir rope is that strand stamen is the guiding principle silk with three strands of folder coir ropes of diameter 22mm, outsourcing PP rope strand) fake of making, cod line is installed in the bottom of net capsule and is connected with net capsule manrope, plays reinforcing mat capsule bottom margin etting; Roll flower with diameter 10mm rope and buckle 4 on cod line, roll flower button and be and reserve one section lax length after rope is passed one of cod line, reserve one section lax length generally than distance 70mm between the flower button, again along cod line interval 150mm left and right, continuity reserves one section lax length after rope is passed one of cod line again, until the fake of cod line is completed the Bu Zha of flower button; The bottom equal decile of etting mesh of net capsule is tied in flower and buckles; Penetrate flower with a diameter 10mm rope and buckle as net capsule lock guiding principle 3, net capsule lock guiding principle one end lies on cod line, takes out tight net capsule lock guiding principle and can pin fish outlet; 0.5 meter sew up a cylindrical shape etting 6 in net capsule inboard far from the base, the cylindrical shape etting adopts the mesh same circumference identical with the net capsule, highly the net sheet of 1 meter is made, because all order numbers of net keed clothing equate with the mesh number of cylinder, so sew up an order along each order pin of level, namely make net keed clothing cover cylindrical shape etting, cylindrical shape etting bottom is passed cod line and is exposed outside the net capsule, make two orders and purpose receipts order mesh 7 with diameter 4mm netting twine on cylindrical shape etting lower edge mesh, pass a diameter 6mm rope as tying rope 5 in receiving the order mesh.When blocking fish outlet, first tighten up tying rope, break into and take out knot, reserve fag end.The cylindrical shape etting that exposes the cod line part is filled in the net capsule, beaten loose-joint with the net capsule lock guiding principle that passes the flower button and pin fish outlet.During hauling, after the net capsule hangs on the deck, take out out the loose-joint on net capsule lock guiding principle, expose the cylindrical shape etting in the net capsule, untie tying rope and just can emit catches.
