Abstract
The utility model relates to a duplex plankton vertical net which is a vertical dragging net used for investigating marine resources and provides a marine resources investigating net that can sample in the same position according to different demands simultaneously, and can avoid sampling result analysis error. The utility model comprises two plankton nets that are suitable for different sampling objects and is characterized in that the net mouths of the two plankton net mouth rings connect as an 8 shape, and two net mouth rings are connected using 5 cross ropes and steel warp while the shorter cross rope in the center is public, and the other four cross ropes are adjusted to a state of net mouth level and connect net mouth rings on the both sides. The utility model can be used as vertical dragging net for investigating marine resources.
Description
Technical field:
The utility model relates to the vertical trawlnet of living marine resources investigation usefulness.
Background technology
Present living marine resources investigation net drags guiding principle, three fork guiding principles, network interface ring, body, net bottom pipe and weight by one and connects to form in regular turn.Difference according to the sampling object, living marine resources investigation net is divided into macroplankton net and microplankton net, and the structure of two kinds of net types has bigger difference, in actual sampling process,, need to take a sample respectively often because of the requirement difference of sampling object in same place with two kinds of netting gears.Under the normal condition, each sample point need spend 90 minutes sample time approximately, because the drift of boats and ships, the sample position of carrying out twice is difficult to be consistent, the error that causes sampling result to analyze easily.
The utility model content
The utility model technical issues that need to address provide a kind of living marine resources investigation net that can take a sample at same position by different requirements simultaneously, avoid causing the sampling result analytical error.
The technical solution of the utility model comprises two plankton nets that are suitable for different sampling objects respectively, the network interface ring that it is characterized in that two plankton nets is linked to be the figure of eight, two network interface rings with 5 fork guiding principles with drag guiding principle and be connected, a middle short fork guiding principle is public guiding principle, and length adjustment to the network interface level of all the other four fork guiding principles connects the network interface ring on both sides respectively.
Because the utility model is made combined plankton vertical web, can make an original investigation website need the investigation that secondary is put net operation only to need the single step of releasing net operation just can finish, control time can reduce to 30～40 minutes from original 80～90 minutes, it is a kind of vertical web of plankton efficiently, simultaneously, owing to sampling, investigation position consistency, can analyse and investigate the plankton stock number of position more exactly, have the technique effect that improves marine organisms investigation efficient.
Description of drawings
What accompanying drawing was represented is structural representation of the present utility model.
Embodiment
Implement concrete mode of the present utility model below in conjunction with description of drawings: the vertical trawlnet of duplex plankton is made up of two plankton nets 5,6 that are suitable for different sampling objects respectively; Plankton net connects and composes in regular turn by draging guiding principle 1, fork guiding principle 2, network interface ring 3, body 4, net bottom pipe 7 and weight 8; Network interface ring 3 welding of two plankton nets are linked to be the figure of eight, two network interface rings with 5 fork guiding principles 2 with drag guiding principle 1 and be connected, a middle short fork guiding principle is public guiding principle, length adjustment to the network interface of all the other four fork guiding principles becomes level and keeps every fork guiding principle stressed evenly, connects the network interface ring 3 on both sides respectively.
