Description
Technical field
The utility model is related to a kind of plankton collecting device, especially suitable and natural water body zooplankter and plant of swimming
The sample collection of thing.
Background technology
Planktonic organism not only predominant number in aquatic ecosystem, and the general sensitiveness of planktonic organism is big, and tool
There is growth cycle short, the advantages of directly can observe identification.Planktonic organism pollutes and trophic level as biological monitoring, evaluating water quality
Important indicator, it is widely used and fruitful both at home and abroad.To understand specific bodies of water plankton community population quantity, advantage
Plant, pollute the item indexs such as indicator species, preliminary assessment is made to the water area water-quality, it would be desirable to which qualitative is done to the waters planktonic organism
And quantitative sampling.
Plankton net is one of the main tool for gathering planktonic organism sample, the big advantage of simple to operate, sampling quantity,
It is generally used in every research of halomereid.In neritic plankton investigation, the difference of the object according to sampling, often
Net has type plankton net of shallow water I, II, III etc..
Chinese patent application publication No.：CN102805055A, Shen Qing Publication day 2012.12.05, disclose a kind of three and float
The biological vertical trawl net of trip, is made up of, it is characterised in that the trawlnet is by 3 forks rack, fork guiding principle, plankton net and weight connection
Guiding principle one end is connected on rack, other end connection weight；3 kinds of specification plankton net network interface rings are fixed to using stainless steel retainer ring
On rack, net bottom pipe is connected respectively on 3 fork guiding principles.3 kinds of specification planktonic organisms can simultaneously be gathered.But, the utility model
Weak point is that plankton net lower end does not have collection device, and the planktonic organism being collected into takes out difficult, meanwhile, it is small-sized to swim
More big-and-middle-sized planktonic organism is inevitably mixed into biological specimen, is inevitably mixed into mesoplankton sample
More macroplankton, generally requires to carry out postsearch screening to the sample for collecting when specific practical, wastes time and energy.
Chinese patent mandate publication number CN202538453U, authorized announcement date 2012.11.21, disclose one kind and swim life
Thing net, is made up of filter and reception device, and the filter is made up of bracing ring and screen cloth, and the bracing ring is located at sieve
Net top；By retainer plate, lucite funnel, clamping device and flexible pipe are constituted the receiving device, lucite funnel it is upper
End is connected with the lower end of screen cloth by retainer plate, and flexible pipe is arranged at the lower end of lucite funnel, and clamping device is on flexible pipe.
The weak point of the utility model is, in actual practical process, due to the vortex that current are produced at glass funnel so that floating
Trip is biological to flow out with current, is difficult to go out aggregation in glass funnel, and the effect of the collection planktonic organism of reception device is bad.
Utility model content
For existing plankton nets when actual planktonic organism gathers, be mixed into microplankton sample compared with
Many big-and-middle-sized planktonic organisms, are mixed into more macroplankton, it is necessary to carry out two to sample in mesoplankton sample
Secondary screening and planktonic organism reception device effect are undesirable, and planktonic organism is difficult the problem of aggregation under the eddy current effect of current,
The utility model provides a kind of combined type plankton net.
A kind of combined type plankton net that the utility model is provided, including
