Abstract

The utility model relates to a fishing net capable of capturing a living jelly fish, belonging to the capture technology of the sea life. The fishing net comprises a net ring, a net bag and a handle, characterized in that: two half-round rings are respectively used as a front half net ring and a back half net ring of the net ring and a round net ring is formed by hinging two ends of the front half net ring and the back half net ring, a limit plate is arranged at one end of the back half net ring; when two half net rings spread 180 degrees, the net rings form the flat round net ring; a rope clasp is arranged in the middle part at the outer side of the front half net ring, a handle is connected with the middle part at the outer side of the back half net ring, the inner sides of the front, back half net rings are respectively provided with a suspension rod or suspension hook; a ring of fine canvas with width of 3-5cm is seamed up at the net mouth of the net bag and a plurality of small holes are uniformly distributed on the seamed fine canvas at the net mouth and a small iron ring is embedded on the small hole and the net bag is coupled with the net ring by making the connection rope pass through the small iron ring hole; the bottom of the net bag is made of the fine canvas and the depth of the bottom of the net bag made of the fine canvas is 35-70cm.

Description

A kind of write by hand net

Technical field

The utility model relates to the marine organisms catching net, especially fishes for the netting gear of jellyfish.

Background technology

The season that large jellyfish breaks out, the ecological severe exacerbation in marine site, the intensive part of jellyfish, the explosion of fishery netting gear, mesh stop up very general, and normal fish production activity is had a strong impact on, and catch reduces, fishes for cost raising, fisherman's burden.Solve this fishery disaster, at first need to find out the history of life of large jellyfish, just need catch a large amount of live body jellyfishes and do laboratory research, yet the main component of jellyfish health is a water, and formed by inside and outside two germinal layers, two interlayers have a very thick mesoglea, and are not only transparent, and floating effect is arranged.In view of this characteristic of jellyfish, if directly go to fish for jellyfish, very easily damage the jellyfish individuality, and jellyfish is individual in case suffer damage and just can't survive, can't do indoor laboratory research with general netting gear.Therefore, need a kind of netting gear of fishing for the live body jellyfish that is specifically designed to, for the ecological Studies of laboratory jellyfish provide technical support.

The utility model content

The problem that the utility model need solve is to create a kind of write by hand net of fishing for the live body jellyfish that is specifically designed to.

The technical solution of the utility model is made up of net circle, mesh bag and handle, it is characterized in that adopting two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively, circular net circle of the hinged formation in two ends of preceding half net circle and later half net circle, limiting plate is established in the end of later half net circle, when being spent, two and half net circle expansion 180 become planar rondure net circle, the outer middle side part of preceding half net circle has the rope clasp, the outer middle side part of later half net circle connects handle, and preceding half net circle and later half net circle inboard are respectively equipped with hanger bar or hanged hook; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, passes little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.

Advantage of the present utility model is and can stays live body jellyfish individuality and seawater in the mesh bag bottom simultaneously, avoid the damage of live body jellyfish, improved the survival rate of live body jellyfish greatly, unnecessary seawater can be discharged by the etting at mesh bag middle part, the folding back of net circle as a lid handle diddle-net flap are lived, and prevent that the jellyfish that catches from escaping.

Description of drawings

What accompanying drawing was represented is net coil structures schematic diagram of the present utility model.

Embodiment

The utility model (referring to accompanying drawing) is by net circle 1, mesh bag and handle 2 are formed, adopt two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively, circular net circle of the hinged formation in two ends of preceding half net circle and later half net circle, the end downside of later half net circle is established limiting plate 3, when being spent, two and half net circle expansion 180 become planar rondure net circle, the outer middle side part of preceding half net circle has rope clasp 5, the outer middle side part of later half net circle connects handle, half net circle was scratched swivel pin with later half net circle is superimposed before the rope clasp of half net circle can make before the pull-up, and preceding half net circle and later half net circle inboard are respectively equipped with hanger bar 4 or hanged hook and mesh bag connection; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, can pass little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.

Claims

1. write by hand net of fishing for the live body jellyfish, form by net circle, mesh bag and handle, it is characterized in that adopting two semicircle circle bodies to net circle and later half net circle as preceding half of net circle respectively, circular net circle of the hinged formation in two ends of preceding half net circle and later half net circle, limiting plate is established in the end of later half net circle, when being spent, two and half net circle expansion 180 become planar rondure net circle, the outer middle side part of preceding half net circle has the rope clasp, the outer middle side part of later half net circle connects handle, and preceding half net circle and later half net circle inboard are respectively equipped with hanger bar or hanged hook; It is the fine canvas of 3-5cm that the network interface of mesh bag is sewed up a circle width, and even distribution aperture is bumped into little iron ring on the fine canvas that network interface is sewed up on the aperture, passes little iron ring hole with connection cord mesh bag and net circle are connect; The bottom of mesh bag adopts fine canvas to make, the dark 35-70cm in mesh bag bottom that fine canvas is made.
