Braided rope for marine fishery trawl

Abstract

The invention provides a braided rope for a marine fishery trawl. The braided rope for the marine fishery trawl comprises a strength component, wherein the strength component is wrapped with a braidedsheath, spiral strands penetrate through the braided sheath, the spiral strands are spirally arranged around the braided sheath, and the pitch of the spiral strands is larger than that of the braidedsheath. The braided rope is low in cost and easy and convenient to implement, the netting gear resistance can be reduced, the trawl lifting force can be increased, the rope manufacturing cost can beeffectively reduced compared with a traditional spiral rope, the drag resistance in water can be effectively reduced compared with a traditional braided rope, and better lifting force is shown on thewater surface, so that energy conservation and consumption reduction are achieved, and the fishing cost is reduced.

Description

technical field [0001] The invention relates to a braided rope for marine fishery trawls, belonging to the technical field of ropes. Background technique [0002] Trawl nets are an important tool for people to fish in the ocean. The trawl nets filter water and move forward, forcing the trawl nets to pass through the aquatic products in the waters and enter the net bags of the trawl nets, so as to achieve the purpose of fishing. [0003] Traditional spiral trawl ropes have low breaking strength. In order to meet the use standard, they often have higher rope weight, which increases the cost of rope production. In actual application, the traditional braided trawl ropes have high water resistance, and cannot show better lift when passing through the water surface at the angle of attack of the trawl net. Contents of the invention [0004] The present invention proposes a kind of marine fishery trawl braided rope for solving above-mentioned deficiencies in the prior art, and co...
