Method for using ship net-cage net gathering device

Abstract

The invention discloses a method for using a ship net-cage net gathering device. During the use of the gathering device, a steel rope positioned at one corner of one net-cage net is enabled to penetrate through a net inlet of a net gathering ring and fixedly bound onto a gathering rotating shaft; crank handles are manually rocked, the gathering rotating shaft is driven by the crank handles throughbearings to rotate, and the net is gradually gathered onto the gathering rotating shaft; when the net-cage net passes through the net gathering ring, oval steel bars of the net inlet isolate part ofwater attached to the net, so that the amount of the water attached to the net can be reduced, and then the net-cage net can be conveniently gathered and transported; a cylindrical gathering net cluster is formed by the net-cage net on the gathering rotating shaft; and after the net is gathered into the cluster, one end of the gathering rotating shaft is dismounted from the corresponding bearing on a vertical column on one side, the gathering rotating shaft is extracted out from the other end, the net cluster is arranged in the rear of a ship body, the extracted gathering rotating shaft is remounted on the gathering device, and the gathering of the next net-cage net is continued. The method disclosed by the invention has the beneficial effects that the design is simple, the use is convenient, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a method for using a fishing net gathering device for a marine net cage. Background technique [0002] Fish farming in cages is one of the important methods of fishery production. In lakes, reservoirs, rivers, coal mining subsidence waters and large ponds, fish farming in cages is often used for convenient management. Fish farming in cages is used to harvest fish. It is necessary to gather the net clothes of the net cages when the net cages exist in the waters for a long time, the net clothes of the net cages are wet, and there are many other attachments such as algae attached to the net clothes, which is extremely difficult to gather, and most of the net cages are set up far away from On the shore, gathering net clothes needs to be operated on board, which increases the difficulty of gathering net clothes in cages. Contents of the invention [0003] In order to overcome the a...
