The beneficial effects of the utility model: this different-grain diameter level plankton gathers and is separated netting gear, the principle be separated is gathered based on plankton, for the shortcoming that Fraction collection process exists, the etting of different mesh aperture is integrated into a device, can by collection be separated required grain-size grade plankton sample and carry out simultaneously.When ensureing that sample can be separated preferably, adopting etting layback chain at different levels to design, collecting each grain-size grade plankton sample easily, greatly reduce operating procedure, improve separation and collection efficiency.The utility model is with the nested feature design of independent assortment, make and operating process simple, without prejudice on the basis of design principle, user can independently increase and decrease different pore size etting by specification demands per sample, is generally applicable to the collection of different-grain diameter plankton component in the water bodys such as ocean, rivers, lake, reservoir, pond, is separated and collects.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
With reference to Fig. 1, that show the concrete structure of the preferred embodiment of the utility model.The design feature of each element of the utility model will be described in detail below, if and when being described to direction (upper and lower, left and right, before and after), be with the structure shown in Fig. 1 for reference describes, but actual user of the present utility model is to not limiting to so.
The utility model provides a kind of different-grain diameter level plankton and gathers separation netting gear, comprise net circle 1 and some ettings 2, each described etting 2 all conically, each described etting 2 is nested one by one from inside to outside, and all enclosed by network interface and lie in net circle 1, the mesh aperture of inner side etting 2 is greater than the mesh aperture of outside etting 2, and mesh aperture successively decreases from inside to outside, can reach the requirement being separated different-grain diameter plankton sample from big to small after filtering water column; Inner side etting 2 net bottom is less than the length of outside etting 2 net bottom to network interface to the length of network interface, and the net bottom of each described etting 2 is all equipped with net bottom pipe 3, and net bottom pipe 3 takes funnel type rotary switch to design.Etting 2 and net bottom pipe 3 be absolute construction, can independently combined nesting or removal different-grain diameter level etting 2 as required, or net bottom pipe 3 at different levels of outwarding winding, with mixed collection Continuous Particle Size level biological sample at any time.Net circle 1 and net bottom pipe 3 adopt the resistance to compression such as stainless steel or copper, corrosion-resistant, on-deformable material is made.Each described etting 2 is all equipped with the layback chain 4 being extended to network interface by net bottom.By the design of layback chain 4, each layer etting 2 all can pull open layback chain 4 and be fixed on bottom etting 2, to collect each grain-size grade plankton by net bottom pipe 3 binding.Also directly can open unwanted grain-size grade net bottom pipe 3 as required, or lay down different-grain diameter level etting at any time to reduce particle diameter progression collection Continuous Particle Size level biased sample.
Described net circle 1 is equipped with every block 5.Described is nylon wire or bolting silk net every block 5, and described etting 2 is for being nylon wire or bolting silk net.Every block 5, other large-sized objects of water body are isolated, both can ensure to collect required grain size specification plankton sample, the effect of protection inner stages etting 2 can be played again.
Described net circle 1 is connected with multi beam pull rope 6, and each bundle pull rope 6 pools a branch of above net circle 1.Also comprise the gravity drop hammer 7 be positioned at below outermost layer etting 2, described gravity drop hammer 7 is connected on net circle 1 by some suspension strops 8.Described gravity drop hammer 7 is plummet.Described suspension strop 8 is the rope made of hemp or nylon rope, and described pull rope 6 is the rope made of hemp or pull rope.
Check net-parts state during use, enclose every block 5 and lie in net circle 1 skin; Aperture each grain-size grade etting 2 from big to small from inside to outside nested enclosing lies in net circle 1 time, and layback chain 4, by net bottom pipe 3 fixation binding at different levels, retracts after screwing its switch by the layback chain 4 that can pull open outer etting 2 again.This different-grain diameter level plankton gathers and is separated netting gear, the principle be separated is gathered based on plankton, for the shortcoming that Fraction collection process exists, the etting 2 of different mesh aperture is integrated into a device, can by collection be separated required grain-size grade plankton sample and carry out simultaneously.When ensureing that sample can be separated preferably, adopting etting 2 layback chain 4 at different levels to design, collecting each grain-size grade plankton sample easily, greatly reduce operating procedure, improve separation and collection efficiency.The utility model is with the nested feature design of independent assortment, make and operating process simple, without prejudice on the basis of design principle, user can independently increase and decrease different pore size etting 2 by specification demands per sample, is generally applicable to the collection of different-grain diameter plankton component in the water bodys such as ocean, rivers, lake, reservoir, pond, is separated and collects.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
