Description
Technical Field
The invention relates to a net throwing mechanism of a fishing boat and an operation method thereof.
Background
A fixed swing arm bracket device is commonly used in a trawler for extending a pulley mechanism to the stern for guiding a net throwing steel cable, so that a net throwing winch is used for rolling the net throwing steel cable to pull out a fishing net from a net rolling machine and release the fishing net into seawater, and the net throwing operation before the trawler fishing operation is completed.
The swing arm bracket assemblies are typically disposed on a working deck one level above the trawl deck. However, for the trawler for continuous pumping operation, because of the use of the continuous pumping system, it is necessary to use a fishing net adapted to continuous pumping, and such net is currently practically used only with a cross bar net, i.e., a net opening is spread by using a cross bar, and there are the following problems:
1. the cross bar can sweep the stern of almost the whole working deck from port to starboard in the process of folding/unfolding;
2. on the working deck, a plurality of shelf slideways are needed to be arranged, on one hand, the shelf slideways are used for guiding the transverse rods when the transverse rods are placed and on the other hand, the shelf slideways are used for storing the transverse rods;
3. both the storage of the cross-bars and the connection/disconnection of the cross-bars to the fishing net require operations on the working deck.
In summary, with practical design requirements and operating practices, the conventional swing arm stand device cannot be arranged on a working deck, otherwise interference occurs, and therefore the conventional swing arm stand device is no longer used in a trawler for continuous pumping cross bar operation.
