Description

The dried small shrimp net

Technical field

The utility model relates to a kind of fishing net, and particularly a kind of being placed on for a long time in the sea is used to fish for the dried small shrimp net of dried small shrimp and so on ocean crops with the change of extra urgent ocean current.

Background technology

The method that the fisherman of Fujian, Zhejiang one band fishes for ocean crops such as dried small shrimp adopts a fishing net (being commonly called as the dried small shrimp net) to be placed on for a long time in the sea always, with fishing for of the mobile passive type of ocean current.Though this catching method is passive, its arrange net many, fishery output is high, ship need not be run, save advantage such as oil plant, gradually replaces active fishing in the past over the years.But this class of Shi Yonging aids such as needing frame bamboo, cursory, weight of throwing the net could allow network interface open in the market, and incompatible operation in extra urgent ocean current.

Summary of the invention

Technical problem to be solved in the utility model has provided and a kind ofly has been applicable to that being placed on for a long time in the sea flows with extra urgent ocean current and fishes for the dried small shrimp net of ocean crops such as dried small shrimp, make the maximized body that enters of impulsive force of extra urgent ocean current, decompose impulsive force, it can avoid adopting complementary tool such as frame bamboo could allow the open trouble of network interface simultaneously.

For solving the problems of the technologies described above, a kind of dried small shrimp net provided by the utility model comprises a net combination, body, net tail, and a net combination, body, net tail are connected in sequence; The combination of net head comprises net wing, interior root, network interface and stay cord, the net wing is provided with along network interface is peripheral, or in network interface, make annular as required and extend shape and from network interface, isolate water inlet, the area of net wing accounts for net wing and more than 30% of the water inlet gross area, outside along the net wing is provided with interior root, is that stay cord is arranged on the interior root; Body is tubbiness; The net tail is round barrel shape.

The dried small shrimp net opens under the effect of extra urgent current.Is following current when the dried small shrimp net is fixed on against the grain direction when being provided with, this moment current strength impact mesh wing, trend is inevitable under the effect of net wing concentrates to body, ocean crops is also inevitable to enter body with trend.The net wing forms the opposite pulling force of direction, dried small shrimp net unfolding under the acting in conjunction of impulsive force and pulling force with trend under the acting in conjunction of drawing wing rope and stay cord.Trend can make body launch after entering body, and the net tail straightens.The fisherman will be equipped with one piece of anchor when using this dried small shrimp net, anchor line fastens stay cord, and stay cord ties up to and draws on the wing rope, and the interior root fixing along the edge of net wing makes fishing net integral body stressed.Begin to take advantage of a situation according to the hard Col branch of custom from body when fishing for and mention body and net tail, unclamp the knot of net tail, take out ocean crops.

The invention has the beneficial effects as follows: easy to operate, network interface opens easily, in extra urgent ocean current operation steady, do not need by other aids.

Below in conjunction with drawings and Examples technology contents of the present utility model is described further.

Embodiment

Among the embodiment as shown in Figure 1, described dried small shrimp net is connected in sequence by net head combination A, body B and net tail C.

As shown in Figure 2, net head combination A comprises stay cord 2, interior root 5, net wing 6, network interface 7.Net wing 6 is provided with along network interface 7 peripheries, or makes annular as required and extend shape 8 and isolate water inlet 9 from network interface 7 in network interface 7; Net wing 6 is made by the screen cloth that no mesh cloth is made or mesh is minimum, and its area accounts for net wing 6 and more than 30% of water inlet 9 gross areas, the specific requirement of shape view mouth 7 and deciding; Purpose is when trend impact mesh because the special material of net wing 6 and enough big area just can stop trend, produces the resistance opposite with the impulsive force direction; Outside along the net wing is provided with interior root 5, is that stay cord 2 is arranged on the interior root 5; Present embodiment is to draw wing rope 3 on interior root 5 earlier, and the adjacent wing rope 3 that draws connects stay cords 2 jointly, and purpose is to avoid too much to cause effect complicated into network interface and that decompose pulling force because of stay cord.Present embodiment net wing 6 is shape ringwise, not having the mesh cloth by several isosceles trapezoids or rectangle is provided with around network interface 7, isosceles trapezoid or the rectangular base of going up are connected with network interface 7, the bottom encases interior root 5, leave the interior root rope that does not encase between the root 5 in adjacent, formation be 4, two of mesh adjacent be on the mesh be equal length arranged draw wing rope 3, stay cord 2 ties up to and draws on the wing rope 3, and stay cord 2 is connected with anchor line 1.The purpose of interior root is the firmness of reinforcing mat wing and makes net wing integral body stressed.Net wing 6 is made of 4 or 8 isosceles trapezoids or rectangle in the present embodiment, and each trapezoidal last base is 1/4 or 1/8 of a network interface 7, and bottom length depends on the circumstances.Under the effect of net wing 6, fishing net just can launch automatically through water impact, and current can flow to body through network interface 7 simultaneously, and ocean crops can enter body with trend.

As shown in Figure 3, body B is tubbiness, is made by the cloth of knotting of certain mesh, and the mesh of body reduces to the net tail gradually from network interface 7 in whole the throwing the net.The present embodiment body adopts has the cloth of knotting of certain mesh to divide 5 to 10 layers to be connected in sequence, and mesh changes from 4.5 centimetres to 0.8 centimetre; Fishing net with 8 layers of specification is connected to example: ground floor mesh size is 1.5 to 4.5 centimetres; Second layer mesh size is 1.3 to 3.8 centimetres; The three-layer network hole size is 1.1 to 3.2 centimetres; The four-layer network hole size is 1 to 2.8 centimetre; Layer 5 mesh size is 0.9 to 2.3 centimetre; Layer 6 mesh size is 0.8 to 1.8 centimetre; Layer 7 mesh size is 0.8 to 1.5 centimetre; Last one deck mesh size is 0.8 to 1.2 centimetre.The fishing net of other specifications is 1.5 to 4.5 centimetres in ground floor mesh size, and last one deck mesh size is that the increase and decrease of each layer is adjusted as required under 0.8 to 1.4 centimetre of constant situation.

As shown in Figure 4, net tail C is round barrel shape, is made by the screen cloth of certain mesh.Present embodiment uses a kind of knotless net cloth that certain mesh arranged to make and forms, and long 7 to 15 meters, the mesh size is 0.5 to 1.2 centimetre.On the net tail, beat a slip-knot during use, or fasten with rope.
