Abstract
The invention relates to a covering net shape optimization method, which relates to masking fishing gear. A covering net adopts a net bag, a body net, an edge net, a bottom ring and a ring rope, wherein the net bag is in a conical shape, and the covering net is characterized in that the body net is in a cylindrical shape, the body net is formed by sewing a net opening section, an intermediate section and a net-bag connection section, the net opening section is connected to the edge net, and the net-bag connection section is connected with the net bag; a transverse straightened perimeter of a netting of each of the net opening section, the intermediate section and the net-bag connection section is identical, and the longitudinal straightened length ratio is 1: 1: 3; the size of each mesh of the net opening section is 140mm, the size of each mesh of the intermediate section is 70mm, and the size of each mesh of the net-bag connection section is 35mm; groups of bottom rings are respectively arranged at the lower edge of the edge net, at the junction between the net opening section and the intermediate section and at the junction between the intermediate section and the net-bag connection section, the distance between every two adjacent bottom rings of each group of bottom rings is 5m, the bottom rings arranged at the lower edge of the edge net are connected with the edge net by virtue of a cross rope, the bottom rings arranged at the junction between the net opening section and the intermediate section are fixed by virtue of a rope, the bottom rings arranged at the junction between the intermediate section and the net-bag connection section are fixed by virtue of a rope, and the ring rope is arranged in the middle of each group of bottom rings in a penetrating manner.
Description
Technical field
The present invention relates to cover fishing gear, especially cover net.
Background technology
Cover net is subordinate to cover class fishing gear, from top to down cover button target fishery harvesting, by infraclass rapid subsidence, and draws network interface in and reaches and fish for object.During operation and light lure to assemble and close, simple and convenient, netting gear cost is lower, and fishing style is energy-conservation, and the Yu Haiyang pelagic fishes that are therefore widely used are fished for.The cover net net type used in current production is all tapered, and netting twine material is monofilament, and sinker and base ring are installed on network interface, size of mesh is reduced to net capsule gradually by network interface, but whole overhead guard net each several part size of mesh is more or less the same, and network interface place size of mesh is about 35mm, and net capsule place size of mesh is 25mm.Due to the limitation of net type, net resistance is comparatively large, and infraclass settling velocity is slow, and cause target fishery harvesting to sink to escaping, have a strong impact on catching rate, for the shoal of fish that point water distribution layer is darker, catching rate is poor.
Summary of the invention
The present invention need solve be to provide a kind of method optimizing cover net net type.
Technical solution of the present invention adopts net capsule, body net, hoddy, base ring, ring guiding principle, and net capsule is tapered, it is characterized in that body net be cylindricality, body net by network interface section, interlude, connect net capsule section and sew up and form, network interface section connection hoddy, connects net capsule section and is connected with net capsule; Network interface section, interlude, laterally stretching girth is equal to connect net capsule section etting, network interface section, interlude, connect net capsule section etting longitudinally stretching length than being 1:1:3; Network interface section size of mesh 140mm, interlude size of mesh 70mm, meet net capsule section size of mesh 35mm; Under hoddy along, network interface section and interlude junction, interlude and connect net capsule section junction one group of base ring is set respectively, adjacent two base ring spacing in each group are 5 meters, be connected along the base ring arranged fork guiding principle with hoddy under hoddy, the base ring rope that network interface section and interlude junction are arranged is fixed, interlude with connect the base ring rope that net capsule section junction arranges and fix, each group base ring centre is installed with ring guiding principle respectively.
Outstanding feature of the present invention is body net is cylindricality, and network interface section and interlude adopt large mesh, and etting over entry during the sedimentation of body net, can reduce etting sedimentation resistance; Cylindricality body net effectively increases netting gear and to surround and seize water body volume, reduces etting and extrudes the fear caused target fishery harvesting; 3 groups of base rings and ring guiding principle are set, when network interface draws in, progressively draw body net network interface section and the interlude of large mesh part in, the fishery harvesting of escaping downwards is upwards driven, prevents fishery harvesting from escaping from large mesh; Base ring is installed on body net 3 positions, can promote the equiblibrium mass distribution of settling capacity, increases network interface settling velocity.The identical net gap perimeter that this method uses in optimizing net type and producing at present, etting longitudinally stretching length are compared with the cover net net type that settling capacity is equipped with, and netting gear settling velocity can improve 30%; Netting gear effectively surround and seize water body volume increase by 35%.
Accompanying drawing explanation
What Fig. 1 represented is structural representation of the present invention.
