Description
Technical field
The utility model relates to a kind of extensible netting gear that the young postlarva in offshore phytal zone is gathered that is used for.
Background technology
In the river, when offshore phytal zone along continuous straight runs such as river, lake are gathered young postlarva, adopt conventional tether to pull method usually, there were two major defects in conventional method: when (1) investigator pulls hawser on the bank in the past; Netting gear receives the component on deflection bank; Make network interface paste bank and advance, can increase the etting wearing and tearing like this, scrape moss or the foreign material of getting the bank simultaneously easily; Influence the collection of young postlarva sample, and increase lethality; (2) receive the restriction of sampled point landform, no matter be fixed point pull (pull the people and fix, people, net distance shorten gradually) still spacing pull that (pulling the people moves; People's net distance is constant); Can't guarantee that all network interface is in level always, when particularly gathering the young postlarva of surface water, the situation of network interface water outlet occur through regular meeting; Can directly influence the estimation of the water yield like this, thereby increase the error of young postlarva quantitative study.Also have the scholar to adopt the method for paddling and pulling, promptly the people pulls netting gear and advances in water, can evade above-mentioned 2 problems so as far as possible; But paddling when pulling netting gear; People's activity meeting forms disturbance to the young postlarva of gathering the waters, makes the confidence level of sampled result descend, during field operation simultaneously;, substrate complicated waters not clear in regimen, the work of paddling has certain danger.When gathering the young postlarva sample of vertical direction, there is the restriction of spatial dimension equally, under the situation by ship or other instruments not, sample range is narrow, operation is inconvenient.
The utility model content
The utility model purpose is to the defective that prior art exists a kind of extensible netting gear that the young postlarva in offshore phytal zone is gathered that is used for to be provided.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
The utility model is a kind of to be used for the extensible netting gear that the young postlarva in offshore phytal zone is gathered, and the young postlarva that it is characterized in that comprising loop bar, the live metal button that can inwardly open of the mobile jib that has the snib hole, welding elasticity snib and have a collection seedling device is gathered net.
Preferably, the mobile jib end is provided with handle.
Preferably, the live metal button is installed the sampling netting gear through the shell fragment that stirs to the inside.
It is further characterized in that: said collection seedling device comprises cylindrical staving and bottom upper shield, and the welding elasticity snib in said staving both sides is used for fixing the said collection seedling device bottom upper shield that has the snib hole, makes collection seedling device bottom closure.
Preferably: said collection seedling device staving bottom is provided with semicircle baffle plate, and upper shield bottom in said bottom is provided with arc baffle plate, and said arc baffle plate is slightly larger than collection seedling device staving bottom semicircular baffle plate; Said arc baffle plate and semicircle baffle combination are used to regulate the openings of sizes of collection seedling device bottom.
The utility model has the advantages that: simple in structure, easy to operate, in the time of can guaranteeing to gather young postlarva in the offshore phytal zone, it is straight that netting gear pulls route, and network interface keeps level, and sample range enlarges, and sample is convenient to collect, and has guaranteed work quality, has improved operating efficiency.

Embodiment
Like Fig. 1, shown in Figure 2, a kind ofly be used for the extensible netting gear that the young postlarva in offshore phytal zone is gathered, the young postlarva that comprises loop bar 2, the live metal button 3 that can inwardly open of the mobile jib 1 that has snib hole 4, welding elasticity snib 5 and have a collection seedling device 9 is gathered net 8.Mobile jib 1 end is provided with handle 6.Live metal button 3 is installed the sampling netting gear through the shell fragment 7 that stirs to the inside.
Comprise cylindrical staving 10 and bottom upper shield 11 like Fig. 3, said collection seedling device 9 shown in Figure 4, the welding elasticity snib in said staving 10 both sides is used for fixing the said collection seedling device bottom upper shield 11 that has the snib hole, makes collection seedling device 9 bottom closure.Through rotation bottom upper shield 11 control sets seedling devices 9 bottom openings size.
Said collection seedling device staving as shown in Figure 5 10 bottoms are provided with semicircle baffle plate 12, and upper shield 11 bottoms, said bottom are provided with arc baffle plate 13, and said arc baffle plate 13 is slightly larger than collection seedling device staving 10 bottom semicircular baffle plates 12; Said arc baffle plate 13 is used to regulate the openings of sizes that collects seedling device 9 bottoms with semicircle baffle plate 12 combinations.
