Detailed Description
Referring to fig. 1 to 4, the trawl truss device for fishing the antarctic krill includes a rotary truss 1, a pulley block 2, a wire rope winch 3, a hydraulic pump station 4, and a wire rope 5. The rotary truss mainly comprises a base 6, a rotary table 7 (including a hydraulic motor and a rotary main shaft), a rotating shaft, a supporting seat 8, a main truss rod 9, a railing 10 and a hoist 11.
The base and the deck of the rotary truss are installed through bolts and nuts, the installation position is close to the side, one end of the rotary truss is installed, and the other end of the rotary truss extends out of the side; the hydraulic pump station is arranged on the deck; the pulley block comprises a first pulley and a second pulley, the first pulley is installed on the deck, the second pulley is installed above the first pulley, and the second pulley is installed and located higher than the main truss 9 and the railing 10. The steel wire rope winch is arranged on the deck; the steel wire rope is led out from the steel wire rope winch, passes through the first pulley and the second pulley in sequence and is connected to a hoist 11 arranged at the tail end of the rotary truss, the hoist 11 is a fulcrum for adjusting the pitching angle of the main truss rod by retracting and releasing the steel wire rope, the pitching angle of the truss can be adjusted by retracting and releasing the steel wire rope, and trawling operation is facilitated.
