Purseseine encircling component and tie method thereof

Abstract

In that invention, a purseseine encircling component and a tie method thereof are disclosed. In order to solve that problem that the existing application polyethylene net wire is made by hands and purseseine encircling is not reliable and the cable is easy to break, the invention relates to a three-force encircling, a float encircling, a edge net sheet and several shrinkage cords and floats. The three-force encircling is arranged in a triangle shape according to the cross section and is tied for binding by a shrinkage cord to form an encircling; the upper edge of the edge net sheet is fixed on the float line by a fixed distance, and the float is formed on the float line, and the float line and the encircling are sequentially killed by the float line. In that invention, the shrinkage cord is adopted to bind the force, the edge net sheet and the float, the water absorb is naturally tightened, the structure of the encircling component is firmly stable, the load bearing strength is large, the service life of the encircling is long, and the edge net sheet has good spreadability and high service performance. The tie method is reasonable, the operation is simple and the efficiency is high.

Description

technical field [0001] The invention relates to a fishing net attachment and its connection, in particular to a large-scale purse seining fishing tackle upper frame assembly and a binding method thereof. Background technique [0002] Purse seine fishing gear refers to a type of belt-shaped net gear that is surrounded by fishing boats to catch fish clusters. It is one of the main fishing gear for marine fisheries in my country. The seine operation is based on the characteristics of the fishing target cluster, using a long belt or a bag with two wings to surround the fish school, so it is called the seine. At present, the length of large and medium-sized seines is generally 800-2000m, and some are more than 2000m. Hundreds of tons or even thousands of tons. Purse seine fishing gear is mainly composed of three parts: net clothes, wires and attachments. The wires mainly include the upper wire, the lower wire, the retraction, the net head, and the side wires. Wait. The functi...

Problems solved by technology

[0003] With the development of pelagic fishery and the enlargement of purse seining gear, the diameter of the rope used is getting thicker and longer, and the length of the rope is getting longer and longer. However, due to the thickening of the diameter of the wire rope and the limited manual strength, it is difficult to tie it firmly with polyethylene wire, so the upper wire often loosens, resulting in unstable shape and structure of the wire rope, twisting deformation, or due to Uneven force causes one of the cables to break and affects the service life of the upper cable
