Description
Technical Field
The invention relates to a knotting net made of filament raw materials, in particular to a large-mesh net ring type knot and an assembling method thereof.
Background
As known, a net sheet is one of the main components constituting a fishing gear, the basic unit constituting the net sheet is a mesh, and a mesh structure formed by weaving a net thread according to a designed shape by knotting knots (or called net knots) or twisting, inserting weaving, braiding, and the like is called a mesh. The shape, specification, node structure and node firmness of the net mesh, particularly the large-mesh net, have obvious influence on the fishing performance of the net fishing gear. The mesh of the mesh net is generally diamond-shaped, one mesh consists of four nodes and four equal-length mesh legs (mesh leg professional term symbol a, the mesh size is 2a, namely the tensioning length among 2 nodes), and the mesh legs are required to be uniform and consistent in length and firm in nodes so as to ensure the accuracy of the mesh and the strength of the mesh sheet. The nodes are effective connection structures among the mesh legs in the large mesh net piece and mainly play a role in limiting mesh size and preventing mesh deformation. The firmness, mesh weaving efficiency, mesh quality, use performance, service life and the like of the nodes are determined by the mode of the nodes. If the knots of the knitted net are loosened, the mesh legs are different in length, so that stress is concentrated on the shorter mesh legs, and the strength of the net sheet is reduced and even the net sheet is damaged; further, the strength of the mesh wire is reduced by the concentration of stress at the nodes, and the mesh wire is most likely to be damaged.
The so-called "big-mesh net" has no clear definition in academia at present, and is only relative to the smaller mesh with the mesh size of 2a less than or equal to 200mm adopted by trawl before 80 years in the 20 th century. With the development of the marine fishing industry, the mesh size of the trawl opening is larger and larger, the mesh size of the trawl opening of the trawl which is the most common water layer-changing trawl at present is 1.00-30.00 m (2 a = 1.00-30.00 m), and the mesh size of some trawl openings is more than 30.00m (2 a =30.00 m). At present, domestic netting machines can be used for weavingThe upper limit of mesh foot of mesh is only a =0.50m, namely mesh size 2a =1.00m, and rope diameter phi =12 mm. And the mesh foot aA mesh of 0.50m still requires hand knitting. The knitting method of the large mesh net is generally insert knitting or knotting knitting. The method comprises the following steps of cutting a net rope into rope sections according to the length of mesh eyes and the rope consumption of knots, and then inserting and weaving the rope sections into eye rings in the shape of a Chinese lute head, wherein the mesh eyes are connected with each other by the eye rings in a sleeved mode to form eye ring knots; the knotting and weaving method is that the end part of the mesh foot is folded after being penetrated with the net rope, the net rope is continuously wound and threaded for two circles at the end part of the mesh foot, and then the net rope is tensioned to form a double-dead-knot (or other mode knots). Meshes woven by the two weaving methods have the problems of low weaving efficiency and uneven mesh foot length, and stress is concentrated on shorter mesh feet due to different mesh foot lengths, so that a mesh rope is easy to break, and a mesh sheet is damaged.
