AI Technical Summary
The prior art is difficult to effectively catch fish in a frame cage with complex structures, especially because the bottom trawl cannot cover the edge of the cage due to the large and small structure of the cage, resulting in incomplete fishing and multiple operations required.
A general fishing device including fixed pulleys, positioning ropes, traction ropes, traction machines and fishing nets is designed. Through the combined structure of fixed pulleys and traction ropes, the fishing nets slide along the inner wall of the frame cage, using floats and elasticity. The design of the grammar is adapted to different shapes and structures, and provides a self-propelled power source through a traction machine to achieve fishing.
It realizes rapid and effective fishing of complex structure frame cages, and can catch all fish in the cages in one go, covering the bottom edge of the cage, avoiding the necessity of multiple fishing.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breeding equipment, in particular to a universal fishing device suitable for frame cages. Background Art
[0002] At present, the main types of offshore cage aquaculture are small wooden raft cages, HDPE cages and large steel structure truss cages. Among them, the small wooden raft cages are smaller in size, and only the aquaculture nets need to be closed to complete the fish collection, without the help of fishing nets.
[0003] However, HDPE cages and some large steel cages need to be fished with bottom trawls in the process of small-scale fishing. Since the frame structure and net shape of HDPE cages and some large steel cages are relatively regular, the outer shape of HDPE cage nets is mostly cylindrical, small at the bottom and large at the top, truncated cone, square, etc. Bottom trawls are usually used to complete fishing well.
[0004] However, in the case of some cages and nets with complex structures, bottom trawling cannot be used. For example, a net is added to the offshore wind turbine duct to form a cage. The outer structure of the cage is larger at the bottom and smaller at the top. When using bottom trawling, the bottom sinker of the bottom trawl relies on gravity to fall vertically to the bottom of the cage. Due to the large bottom and small top structure of the duct cage, the sinker falls vertically from a smaller area on the top of the cage to the bottom of the cage and cannot reach the larger bottom edge of the cage, thereby failing to catch the fish at the edge of the cage. Multiple catches are required and it is still impossible to catch all the fish in the cage. Utility Model Content
