A kind of fishing boat fish-catching apparatus
Technical field
The present invention relates to a kind of Fishing tool, especially a kind of fishing boat fish-catching apparatus be arranged on fishing boat.
Background technology
Fish-catching apparatus is in the market numerous in variety, configurations; Fishing netting gear is mostly spread from the top down, adopt trawlnet, cast net, draw in the net, lift the methods such as net and fish, but these means is larger due to sound time off line, are easy to the shoal of fish to startle, and frightened away by the shoal of fish.
Chinese invention patent application ZL201310433050.4 discloses a kind of fishing boat fish-catching apparatus, comprise net cage, enter network interface, framework, attracting bait, nettle, ball float, halliard a, pulley a, bracing frame, halliard b, pulley b, capstan winch b, pillar, capstan winch a, link and hook, net cage is cylinder, net cage is made up of framework and fishing net, net cage is provided with into network interface, entering network interface is taper, has one to put lymphogranuloma inguinale bottom net cage; Halliard a one end is provided with a hook, and the other end is connected on capstan winch a, middle through pulley a; Pulley a is contained on bracing frame, and bracing frame is arranged on fishing boat by hinge, and capstan winch a and capstan winch b is arranged on fishing boat; Halliard b one end is fixed on bracing frame, and the other end is fixed on capstan winch b, and middle through pulley b, pulley b is arranged on pillar, and pillar is fixed on fishing boat; Three nettle one end are fixed on net cage frame, and the other end is fixed on ball float, and be provided with a link above ball float, the hook on halliard a hooks link.This device is less by fishing boat to be separated the noise effect making the net cage being placed in water be subject on fishing boat with net cage, but the process of placing net cage still can produce relatively large noise, and this apparatus structure is complicated and the hull space taken is larger, reduce the useful load of fishing boat, still have the space of improving further.
Summary of the invention
The object of the present invention is to provide a kind of noise less, take the less and simple fishing boat fish-catching apparatus of structure in fishing boat space.
To achieve these goals, the present invention adopts following technical scheme:
A kind of fishing boat fish-catching apparatus, comprise be launched into cone-shaped revolve net, describedly revolve that be connected with can by the described tow strap revolving net pull-up on the net, one end of described tow strap with described revolve to net be connected, the other end is connected with the winch be arranged on hull, described revolve be provided with on the net be looped around described in revolve the flexible pipe of net surface, described flexible pipe is arranged or is connected with aerating device, multiple gravity block be evenly arranged is provided with bottom the described cone-shaped revolving net, preset distance is separated with between described flexible pipe and described gravity block, described revolve also be provided with on the net along described in revolve net the pressure graticule that arranges of cone-shaped generatrix direction, one end of described pressure graticule is connected with the pressure mark bowl be arranged on described flexible pipe, the other end is connected with buoy.
Adopt technique scheme, revolve after net puts into water as fishing net, inflated in flexible pipe by aerating device, inflate later flexible pipe to drive and revolve net and launch on the water surface, whole process noise is less, and in addition, the part that fishing boat fish-catching apparatus of the present invention is arranged on hull only has winch, take hull space less, and structure is simple.
As a modification of the present invention, described aerating device comprises the gas tube that the inflator be placed on hull is connected with described inflator with one end, and the other end of described gas tube is connected with described flexible pipe.By above-mentioned improvement, be convenient to inflate flexible pipe.
