Abstract

The invention discloses an oceanic drift netter. The oceanic drift netter is mainly composed of a drift netter body, a drift net, two hydraulic net-drawing folding-arm cranes, two guide grooves, a net unfolding frame, a high-pressure water spray net washing device, a net folding machine and a net casting and arranging machine. The hydraulic net-drawing folding-arm cranes comprise telescopic suspension arms, rotary plates and stand-column-type bases. One end of each telescopic suspension arm is arranged on the corresponding rotary plate, the rotary plates are arranged on the stand-column-type bases, the other ends of the telescopic suspension arms are provided with integrated double rope reeling machines, the lateral portions of the stand-column-type bases are provided with foldable frames, single rope reeling machines are arranged on the foldable frames, and one end of a main rope of the drift net and one end of a bottom rope of the drift net are wound through the integrated double rope reeling machines and the single rope reeling machines respectively. Drift netters constructed through the production equipment and facilities achieve mechanical assembly line operation in production processes from net casting, net drawing and net arranging, the technological difficulty that in a traditional production technology, large drift nets are hard to cast is solved, and the drift netters are made to have the capacity for effectively developing fishery resources of the upper layers of open waters of the South China Sea.

Description

technical field [0001] The invention relates to a fishing boat, in particular to an oceanic current gillnet fishing boat. Background technique [0002] Oceanic fishery refers to fishing in the high seas, and the species caught are oceanic migratory fish, such as tuna and squid. The gillnet fishing vessel engaged in the above-mentioned oceanic fishery is called the oceanic gillnet fishing vessel. This fishing vessel is generally a large vessel. The gillnet is mainly used to catch migratory fish. The gillnet uses a layer or Rectangular mesh made of multi-layered plastic wire, generally multiple meshes are combined together, with multiple floats made of sponge plastic on the upper edge, and lead sinkers attached to the lower end, vertically stretched near the sea level A nearby location, waiting for fish to swim in and get entangled in the mesh. Because it moves with the current and the entangled fish hang on the net like a thorn, it is called "drift gillnet". The gillnet fi...
