Embodiment
For further setting forth the utility model, reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, artificial fish-aggregating device embodiment, structure, feature and effect thereof to according to the utility model proposes, be described in detail as follows.
As shown in Figure 1, a kind of artificial fish-aggregating device of the utility model, comprises float 1, positioning buoy 2, net sheet 3, expansion bracket 4, constriction device 5, hook 6, cross tube 7 and sheer pole 8.
Described float 1 is connected with positioning buoy 2, and net sheet 3 is located at float 1 below.Described float 1 is comprised of a plurality of, by rope, is cascaded.Described cross tube 7 and sheer pole 8 are installed in respectively the upper/lower terminal of net sheet 3.
Described expansion bracket 4 is combined by a plurality of X crossbar groups, and by expansion bracket 4 supporting network sheets 3.Pole 44 intersections that described each X crossbar group is made by two aluminum alloy materials form, on aluminum alloy materials, be provided with blue coating, can increase shoal of fish congregational rate, can also make smooth surface, the friction of minimizing to net sheet 3, can be utilized effectively net sheet 3.
At two poles, 44 intermediate interdigitated points 41, by bearing pin 42, connect and be fixed on net sheet 3, and can mutually rotate between two poles 44, between described adjacent X crossbar group, at both ends, by bearing pin 43, be connected, and rotatable between the pole between adjacent X crossbar group, bearing pin 43 is connected on net sheet 3.Specifically, the intermediate interdigitated point of expansion bracket 4 and two ends infall are all rotatable, to make expansion bracket 4 folding.
Described expansion bracket 4 upper ends are an end points of two poles, these two end points are connected with cross tube 7 by hook 6, described expansion bracket 4 lower ends are also an end points of two poles, these two end points are connected with sheer pole 8 by hook 6, described hook 6 is fixing on upper and lower cross bar by steady pin 9, links up with 6 and can on upper and lower cross bar, move when steady pin 9 unclamps.Described upper and lower cross bar surface adopts smooth, can reduce like this hook 6 resistances that slide.
The height that described expansion bracket 4 stretches rear and net sheet 3 matches, and makes net sheet 3 flexible in short transverse with expansion bracket 4, makes net sheet 3 in the strand time receiving, can not be intertwined, and also can not have influence on and use next time.
Described expansion bracket 4 can be also the structure that covers upon deployment a side net sheet 3, and net sheet 3 is flexible with expansion bracket 4 like this, makes net sheet 3 in the strand time receiving, can not be intertwined, and does not also affect and reuses, and increases the service life of artificial fish-aggregating device.
As shown in Figure 2, described constriction device 5 consists of outer cover 51, spool 52, spring steel plate 53, locking key 54, volume groove 55, spring 56 and securing member 58.
As shown in Figure 3, described outer cover 51, for bottom is provided with the cuboid of groove 57, is stuck on cross tube 7 by groove 57, and by securing member 58, outer cover 51 is fixed on cross tube 7, and this securing member 58 can be screw, bolt etc.Spool 52 is arranged on centre position in outer cover 51 and rotatable, described volume groove 55 is fixed on spool 52, described spring steel plate 53 is looped around on volume groove 55, and spring steel plate 53 one end are connected with sheer pole 8, spring 56 is arranged in outer cover 51, these spring 56 one end are connected with spool 52, and its other end is fixed on outer cover 51 inside top, by pulling spring steel plate 53 to make spring 56 produce elastic force.Locking key 54 is arranged on outer cover 51 outsides, and this locking key 54, through outer cover 51 and corresponding with spring steel plate 53, rotates to control spool 52, specifically, when pressing locking key 54, locking key 54 stops spool 52 to rotate, thereby constriction device 5 is quit work.
When constriction device 5 drives net sheet 3 to open, upper and lower cross bar, apart from increase, pulls spring steel plate 53, thereby drives volume groove 55 and the fixing spool 52 of rolling up groove 55 that spring steel plate 53 is wound around to rotate, thereby net sheet 3 is opened.Make the spring 56 being connected with spool 52 open generation elastic force simultaneously.
When net sheet 3 opens completely, press locking key 54, locking key 54 is contacted with spring steel plate 53, thereby spring steel plate 53 is blocked, can not move.When strand is received artificial fish-aggregating device, start locking key 54, the elastic force effect that recovers deformation generation due to the spring 56 in constriction device 5 rotates backward spool 52, thereby spring steel plate 53 is produced to upper pulling force, contributes to the folding strand of net sheet 3 to receive.
While throwing in the utility model artificial fish-aggregating device, by unscrewing steady pin 9, make to link up with 6 and slide on upper and lower cross bar, with this, control the shape of expansion bracket 4 and net sheet 3, when expansion bracket 4 launches, tighten steady pin 9 and make to link up with 6 and be fixed on upper and lower cross bar to maintain the shape of expansion bracket 4 and net sheet 3.When strand is received artificial fish-aggregating device, steady pin 9 is unclamped and makes to link up with 6 and again on upper and lower cross bar, slide, after expansion bracket 4 is folding together with net sheet 3, tighten steady pin 9, make expansion bracket 4 keep folded states.The utility model artificial fish-aggregating device is easy to operate in fishery operation process, can reach convenient strand and receive so that the effect of again utilizing.
In sum, every the utility model technique scheme content that do not depart from, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
