Description
Technical field
The utility model relates to fishing tool field, in particular to a kind of small-sized multi-layer trawl.
Background technique
In fishery resources survey and evaluation process, Research Team establish " reflection sounding+target strength simulation model+
The off-lying sea multiple types fisheries stock assessment technology of frequency difference technology+biology trawlnet sampling ".It is aobvious by the monitoring of continuous acoustic technique
Show, the biomass of South Sea middle layer fish is huge, is one of the main drive of deepsea ecosystem substance circulation and energy flow, tool
There are huge researching value and exploitation prospect.
The investigation for carrying out middle layer fish will also combine " sampling of biology trawlnet " technology other than Acoustic assessment.
" sampling of biology trawlnet " common operation mode has single ship to have wing list capsule trawlnet at present.The performance of Trawl gear,
Directly affect the effect of acquisition.Traditional fish production net is big to Vertical movements range, the unconspicuous middle layer fish fishing of cluster
Efficiency is lower, is unfavorable for implementing controlled directed fishing.Based on traditional fish production netting gear there are the shortcomings that, Research Team is in existing net
It is optimized on the basis of tool, has developed a kind of small-sized multi-layer trawl equipment for grinding investigation suitable for middle layer Gyrinocheilidae, it is full
Foot investigation operation actual requirement.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high small-sized multi-layer trawls of catching rate.
Used technical solution to solve above-mentioned technical problem：A kind of small-sized multi-layer trawl, including it is upper net plate, off line
The upper net plate, lower net plate and two side mesh sheet are sutured by stitch-bonding processes and to form body by piece and two side mesh sheet, net
Body one end forms net capsule, and the body other end forms opening, and the upper net plate is provided in the opening with exaggerated, and the lower net plate is being open
Place is equipped with infraclass, and the side mesh sheet is provided in the opening with side guiding principle, and in side, the end of sewing up of mesh sheet and upper net plate is connected with upper manrope,
In side, the end of sewing up of mesh sheet and lower net plate is connected with lower manrope, and the free end of the upper manrope and lower manrope is connected to net
The upper and lower ends of plate side are connected in the middle part of the web plate other side and drag guiding principle.
Further, the upper net plate, lower net plate and side mesh sheet are the mesh sheet made of polyethylene.
Further, described exaggerated equipped with float, the infraclass is equipped with sinker.
Further, the upper net plate, lower net plate and side mesh sheet are equipped with wing.
Beneficial effect：Upper manrope and lower manrope one end are connect with suture end, the upper and lower ends connection of the other end and web plate,
It drags guiding principle to be connected on research vessel, research vessel pulls trawlnet, and under the action of water flow, web plate is in vertically, in web plate and side guiding principle substantially
Under the action of, so that trawlnet maintains a vertical bore, catching rate is considerably increased, especially for Vertical movements range
Fingerling that is big and dispersing cluster, better effect.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawings and examples：
Fig. 1 is the fishing status diagram of the small-sized multi-layer trawl of the utility model embodiment.
Specific embodiment
Referring to Fig.1, a kind of small-sized multi-layer trawl of the utility model embodiment, the trawlnet is by draging guiding principle 2, web plate 3, upper manrope
4, lower manrope 5, exaggerated 8, infraclass 9, side guiding principle 6, float 7, sinker, body 11 and net capsule 12 form.Wherein, body 11 is by surfing the Internet
Piece, lower net plate and two side mesh sheet are sutured by sewing process, and 11 one end of body forms opening, and upper net plate is being opened
Exaggerated 8 are equipped at mouthful, lower net plate is provided in the opening with infraclass 9, and 11 other end of body sutures to form net capsule 12.Side mesh sheet is being open
Place is equipped with side guiding principle 6, and in side, the end of sewing up of mesh sheet and upper net plate is connected with upper manrope 4, and in side, mesh sheet and lower net plate sews up end
Portion is connected with lower manrope 5, and the free end of upper manrope 4 and lower manrope 5 is connected to the upper and lower ends of 3 side of web plate, and web plate 3 is another
It is connected in the middle part of side and drags guiding principle 2, the other end for draging guiding principle 2 is connected on research vessel 1.
Upper manrope 4 and lower 5 one end of manrope are connect with suture end, and the other end is connect with the upper and lower ends of web plate 3, drags guiding principle 2
It is connected on research vessel 1, research vessel 1 pulls trawlnet, and under the action of water flow, web plate 3 is in vertically, in web plate 3 and side guiding principle 6 substantially
Under the action of, so that trawlnet maintains a vertical bore, catching rate is considerably increased, especially for Vertical movements range
Fingerling that is big and dispersing cluster, better effect.
Preferably, float 7 and sinker are separately positioned in exaggerated 8 and infraclass 9, in the booster action of float 7 and sinker
Under, the opening upper and lower ends of body 11 traction by buoyancy and gravity respectively, so that trawlnet can maintain during fishing
Larger open.In the utility model float 7 and sinker drift along it is bigger, i.e., suitably increase float 7 be subject in water it is floating
Power, while the appropriate gravity for increasing sinker itself, it is biggish drift along it is bigger than being conducive to increase the opening of trawlnet in the vertical direction
It is small, to further increase the catching rate of the fingerling of dispersion cluster.
Specifically, upper net plate, lower net plate and side mesh sheet are the mesh sheet made of polyethylene in the present embodiment.Meanwhile
Upper net plate, lower net plate and side mesh sheet are equipped with wing 10, and wing 10 is compiled by the polyethylene cable that structure number is 25tex × 3
It knits.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
