Novel offshore fishing device

Abstract

The invention relates to a novel offshore fishing device, and belongs to the field of offshore fishing devices. The novel offshore fishing device comprises a hull, hanging arms, a fish net, capstans, fixed pulleys, halyards, a jack stay, a net drawing rope, hoops, a fishing containing net, falling blocks, a contracting opening, a fishing net, hanging rings and a net cover. The fish net is formed by sleeving of the fishing net and the fish containing net, the hoops are arranged on an inlet and an outlet of the fishing net, the outlet of the fishing net is the contracting opening, the inlet of the fishing net is provided with the net cover, an opening of the net cover is bound on the jack stay by the net drawing rope, the hanging rings are welded on the left and right sides of the hoop at the inlet end of the fishing net, the fish net is hung on the hanging arms through the halyards, the top and the tail of each hanging arm are provided with one fixed pulley and one capstan respectively, each halyard is wound on the corresponding fixed pulley to be coiled on the corresponding capstan, and falling blocks are annularly mounted on the periphery of the fish containing net with tail expanded by the corresponding hoop. Therefore, by the device, the problems that a large number of fishes escape from the opening of the fish net when a common fish net is drawn, net drawing completely depends on manpower to cause waste on time and labor and catchable depth adjusting range is limited are solved.

Description

technical field [0001] The invention relates to a novel sea fishing device, which belongs to the field of sea fishing devices. Background technique [0002] Fishing is a way for people to develop the ocean, and it is also a basic means for coastal residents to obtain economic income. Fishing nets are the most commonly used fishing tools. The renewal and transformation of fishing gear is an important way for fishermen to increase their fishing output. Gradually reduce people's attention to the deep sea with a larger fish volume. Although there are electric fishing methods and trapping methods with stronger fishing capabilities on the market, the country has great restrictions on these extinction fishing methods, and people usually use them. Fishing nets are fished by trawling, casting, pulling and lifting nets. Due to the structural design flaws of these fishing nets, a large number of fish escape from the openings of the fishing nets when the boat stops to collect the nets. ...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that a large number of fish escape from the opening of the fishing net when the ordinary fishing net is collected, and it is time-consuming and laborious to completely rely on manual collection of the net, and the range of depth adjustment that can be caught is very limited.
