AI Technical Summary

Technical Problem

The lack of gillnetting equipment on existing gillnet fishing vessels results in insufficient opening area when drift gillnets are launched, leading to reduced catch and lower economic benefits.

Method used

Design a net-laying frame for gillnet fishing boats, comprising a fixing block, a curved groove, a small gear, a large gear, and a motor. The gear system controls the raising and lowering of the fishing net, ensuring smooth movement and unfolding of the net in different positions.

Benefits of technology

It increases the opening area of ​​the fishing net, avoids the danger of the net being caught in the water flow during operation, saves energy consumption, and prevents the net from getting tangled at bends, ensuring fishing efficiency and safety.
