Abstract
The utility model belongs to the improvement of a fishing trawlnet. A net surface with diamond meshes is made into three layers. Symmetrical large holes on the net surfaces on the both sides of the utility model is four times to six times as much as small holes on a middle net surface. Compared with the original single layer fishing trawlnet, the utility model is suitable for fishing in rivers, lakes, and offshores with the advantages of high fishing yield, long service life, etc. In addition, the net surfaces can not be damaged easily.
Description
The utility model belongs to the improvement of fishing with linked network.
Fishing linked network commonly used is the individual layer wire side, and it is to be provided with float, bob formation fishnet at the upper and lower guiding principle rope place of wire side.This net can only be caught the fish of certain specification owing to be the individual layer net surface structure, makes the yielding poorly of its fishing; Fish can cause the service life of wire side low in the collision of individual layer wire side.
The purpose of this utility model is the shortcoming at above-mentioned existence, provides a kind of fishnet to prolong the fishing linked network that the output of fishing improves service life.
Technical essential of the present utility model is: the wire side of prismatic mesh is made three layers, and the symmetrical macropore of both sides wire side (3) is 4-6 a times that middle wire side (4) is gone up aperture.
The utility model is compared with original individual layer fishing linked network, has fishing output height, and wire side is advantage such as fragile long service life not.Being applicable to rivers and lakes and offshore fishing, is comparatively ideal Fishing tool.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Wire side (4) is little mesh in the middle of of the present utility model, and both sides are the big mesh wire side of each a slice (3), and the mesh of both sides wire side is got onesize, is assembled between the infraclass rope.The rope (2) of raising to the higher plane of principle has foam plastic float (1), and infraclass rope (6) has metal drops (5), and the three-layer network of composition is through the effect of float and bob, and both sides macropore wire sides (3) show vertical up and down, and middle wire side (4) is loose state.During use, after both sides came fish to creep into macropore, wire side was stretched and is become pocket in the wire side macropore of opposite fish is caught in the middle of the aperture.Home Network can be according to the height of the depth design grid seedling of water, and the depth of water is then high, and water is shallow then short, goes out five meters as the net height of seedling and can add the waist guiding principle in the centre of three-layer network, so that use.
Claims (1)
1, a kind of three layers of fishing linked network have wire side, guiding principle rope, float, bob, it is characterized in that the wire side of prismatic mesh is made three layers, and the symmetrical macropore of both sides wire side (3) is 4-6 a times that middle wire side (4) is gone up aperture.
