Abstract
The utility model relates to a ladder-shaped net grid of a bottom trawlnet, particularly a deep-water single-boat bottom trawlnet. The technical problems to be solved are to simplify a floppa, reduce net consumption, reinforce an escape preventing effect and enhance fishing rate. The technical scheme of the utility model comprises a net bag. The utility model is characterized in that a ladder-shaped net grid with the taper ratio of 2: 1 is arranged in the net bag, the wide edge of the net grid is sewn with the back part of the net bag and the cutting edge of the net grid is sewn with the front part of the net bag. The utility model is suitable for fishing boats of 441KW-735KW to carry out deep-water single-boat bottom trawlnet fishing.
Description
Technical field:
The utility model relates to deep water list boat bottom layer trawlnet.
Background technology
At present, to fish for middle-size and small-size single boat bottom layer trawlnet of deep water cod, the infundibulate floppa is set in the body final stage, the infundibulate floppa not only has the function that the obstruction catches are escaped from body, can also play the effect of guiding, guiding to fish.But the infundibulate floppa is formed by six trapezoidal joinings, and technology is bar again, and the etting consumption is many, forms the net resistance increase, and the inaccessible phenomenon of floppa easily takes place in operation, can reduce the network access rate, gives simultaneously to fish for to operate and makes troubles.
The utility model content
The utility model technical issues that need to address are simplification floppas, reduce the etting consumption, strengthen to hinder and escape effect, improve the fishing rate.
The technical solution of the utility model comprises the net capsule, it is characterized in that being provided with a taper ratio and be 2: 1 trapezoidal net grid in the net capsule, and net grid width limit and net capsule back are sewed up, the cutting edge of net grid and the stitching of net capsule belly.
The utility model is provided with the net grid at the net capsule and only needs the trapezoidal etting of a slice, compare with the infundibulate floppa in being arranged on the body final stage, the etting consumption obviously reduces, replaces infundibulate net tongue with the net grid, simplify technology, in operation, no longer included the inaccessible phenomenon generation of floppa, effect is escaped in the resistance of fishes and shrimps also be enhanced, have the technique effect that improves the fishing rate.
Description of drawings
Accompanying drawing is represented is arranged on trapezoidal net grid schematic diagram in the net capsule.
Embodiment
The utility model adopts a taper ratio is set in net capsule 1 is 2: 1 trapezoidal net grid 2, and the broadside of net grid 2 is sewed up with net capsule back, the cutting edge of net grid 2 and the stitching of net capsule belly.As being example with the used trawlnet 3 of 735KW fishing boat, net bag beam degree is 96 orders, highly is 100 orders, size of mesh is 70mm, and the net sheet specification of then trapezoidal net grid is: width is 96 orders, height 30 orders, side taper ratio 2: 1 (the brief number of net sheet N-meshes and T-meshes), size of mesh is 70mm; Sighting slits such as the back employing of its broadside and net capsule close, and the belly of hypotenuse and net capsule is sewed up.The utility model is applicable to that the 441KW-735KW fishing boat carries out the trawling of deep water list boat bottom layer.
Claims (2)
