The mesh number of net is more than the mesh number of the cutter;
The ring pipe includes multistage unit pipes, is connected to by neck tube between the adjacent unit pipes, the neck tube it is straight
Diameter is less than the diameter of the unit pipes, and ring pipe top side wall is equipped with water inlet pipe.
Preferably, the trawlnet is equipped at least one escape with the cutter junction close to the ring pipe side
Mouthful.
Further, the cutter is equipped at intervals with sawtooth piece.
Preferably, corresponding two sides of the ring pipe are connected with lanyard, and described lanyard one end is connected with link.
Further, the trawlnet two bottom sides are equipped with multiple sinker rings along trawlnet length direction.
Preferably, it is passed through on the inside of the sinker ring and is provided with net collecting rope.
Further, the net collecting rope is connected to by pulley on the link.
Preferably, the mesh number of the net capsule is more than the mesh number of the trawlnet.
Further, the net capsule tail portion is equipped with necking rope.
Preferably, the movable device is equipped with multiple connecting rods towards outside divergence expression.
The beneficial effects of the invention are as follows:
(1) ring pipe is rubber hose material, prevents water pollution, and ring pipe includes multistage unit pipes, adjacent cells pipe it
Between be connected to by neck tube, the diameter of neck tube is less than the diameter of unit pipes, and ring pipe top sidewall is equipped with water inlet pipe, passes through water pump
Connection water inlet pipe is to pumping inside ring pipe, and when ring pipe internal pressure increases, ring pipe can become quadrilateral structure, can
It realizes that ring pipe automatically switches shape, controls flow and hydraulic pressure in trawlnet, prevent the feeler of jellyfish from hanging on cutter, influence
Capturing efficiency.
(2) cutter can cut jellyfish small, while discharge the fish in jellyfish and shrimp, and cutter is leaned on trawlnet junction
Nearly ring pipe side is equipped at least one escape mouth, and fish is entered by mouth of escaping in water with shrimp, will while realizing jellyfish fishing
All fishery are released effectively, and realize fishery resources sustainable development.
(3) net capsule tail portion is equipped with necking rope, need to only be fastened necking rope when capturing jellyfish, and the mesh number of net capsule is more than cutting
Device, the jellyfish filtered out by cutter enter net capsule with other biologies, are filtered again by net capsule, can be by other in jellyfish
Biofiltration is gone out.
