Abstract

The utility model relates to a fishnet, which is composed of a netting and a net rope. The fishnet is sewed by four pieces of nettings. Simultaneously, a belly netting and a back netting 17 are the same. Nettings 17 on the both sides are the same. A plurality of rows of hexagonal meshes are arranged on a net body 3. A sleeve net 1, a net mouth 2, and the rest part of the net body are rhombuses. The sleeve ends of four long force rope self nets penetrate through the integral net body at the sewing points of the four pieces of the nettings. When the utility model is used for capture pelagic fishes in a sea, because the hexagonal meshes have good expanding property, the utility model has the advantages of the reduction of the resistance of the nets, the improvement of the stressed state of the nets, the reduction of the damage of the nets, the improvement of the towing speed of a dragnet fishing boat, the improvement of capture amount, the reduction production cost, and low manufacture cost which is lower than a purse net and a flow net and is the same with a dragnet.

Description

Fishnet

The utility model relates to the fishing net that fishing is used in a kind of ocean, particularly catches the fishnet of pelagic fishes.

Now in China coastal waters, demersal fishes natural resources shortage, and fish resources at the middle and upper levels is abundant, but the netting gear of fishing for pelagic fishes is purse seine, drift net or otter-trawl.It is little that these netting gears have mesh, thereby netting gear small scale, resistance cause the fishing boat towing speed to slow down greatly, frighten shortcomings such as fish in addition as square, and quantity of the catch is reduced, the rising of fishing cost.

Thereby the purpose of this utility model provides a kind of being fit to and catches the fishnet raising quantity of the catch of ocean pelagic fishes and reduce and fish cost.

The purpose of this utility model is achieved in that

Fishnet is made up of four ettings, and is made abdomen back of the body etting identical, the both sides etting is identical; Body is that many rows are hexagonal mesh simultaneously; Run through just body by 4 manropes from the sleeve end of net at four joining places.

Catch pelagic fishes in the ocean with the fishnet that the utility model provides, can improve quantity of the catch.Because hexagonal mesh has good spreading performance, thereby significantly reduces the resistance of netting gear, improves the netting gear stress, reduce the damage of netting gear, improve the towing speed of trawler, thereby improved quantity of the catch, reduce production costs; This fishnet cost is lower than now general purse seine drift net simultaneously, and is identical with trawlnet.

Further introduce the utility model below by accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model abdomen tergite structural representation;

Fig. 3 is the utility model left and right sides chip architecture schematic diagram.

From accompanying drawing, can see, the fishing net that the utility model provides, front end has that to drag its an end bolt of guiding principle 15 solid on trawler, the other end links to each other with empty guiding principle 14, empty guiding principle 14 has 4, the other end of empty guiding principle 14 links to each other with the node of manrope 13, left and right sides guiding principle 12, upper infraclass 11 again, thereby with guiding principle a just individual net is connected. Just a net is made up of the identical abdomen back of the body etting 16 of size structure and the identical left and right sides etting 17 of size structure, these four nets are stitched together, and form 4 sutures, and at suture manrope 13 are arranged, manrope 13 is from the beginning of sleeve end until the afterbody of net runs through a just body. Sleeve net 1, network interface 2 are diamond mesh, many row's hexagonal meshes are arranged on the body 3, and body 4 to body 9 are the diamond mesh net, and body 10 is keed.

Embodiment: the long 28m diamond mesh of sleeve net.The big 8m of order, all orders of network interface are 40 orders, tension girth 320m, the long 67.75m of body net, continuous from front to back three orders of body net are the hexagon mesh, and order is respectively 10m, 8m and the vertical stretching length of 6.5m(greatly) be diamond mesh later on, order is respectively 4m, 2m, 1.25m, 0.8m, 0.4m, 0.2m, 0.15m and 0.10m greatly, the long 14.6m of keed, the big 65mm of order, each one of last infraclass, length 63.2m, two of side guiding principles, long 52.4m, hexagon net dilatancy is good.

Claims

1, a kind of fishnet is made up of etting, the head rope, it is characterized by: fishnet is seamed into by 4 ettings, and abdomen back of the body etting 16 is identical, and both sides etting 17 is identical; Body 3 has many row's hexagonal mesh; Run through a just body in 4 manropes 13 in four joining places by the sleeve end.
