Abstract
The utility model discloses a plankton collection net, include the mount and fix at at least two plankton net s of this mount with one side, plankton net is including fixing net gape, primary filter screen, connection etting and connection the sampling bottle in etting bottom net gape below of suit on the net gape on the mount, the etting top is equipped with the pore size diverse of opening, every etting for filter different types of plankton, primary filter screen's aperture is greater than the aperture of etting for screen out the debris of aquatic. The problem of gather the netting gear among the prior art and often can run into entering netting gears such as impurity, rubbish and do not lead to the fact the drainage smooth etc is solved, but and two kinds of plankton samples of simultaneous acquisition, improve greatly and gather efficiency. The utility model has the advantages of being simple in structure and convenient in operation, low cost is applicable to the collection of plankton sample in the storehouse of lake, and once gathers two kinds of plankton samples, satisfies the sampling requirement of water environment plankton monitoring.
Description
Technical field
This utility model belongs to plankton nets technical field, and in particular to a kind of plankton nets.
Background technology
At present, China's water pollution problem is projected, and the data display of Ministry of Water Resources's Environmental Monitoring Report, current China has 1/3
Important service reservoir reaches eutrophication, and thus the safety problem of caused reservoirs drinking water source receives much concern.In order to ensure
The sustainability that reservoir supplies water, it is important to the protection exception of Reservoir Water Quality.
Plankton is one of biological group main in reservoir water body, including phytoplankton and zooplankton, in reservoir
Ecosystem material is circulated and plays vital effect with energy Flow.Phytoplankton is the primary producer of water body, its
The change that species is constituted and distribution has indicative function, environmental condition to environmental change can directly or indirectly have influence on plant of swimming
The structure of community of thing.Zooplankton is the Primary consumer of aquatic ecosystem, and the change of its type and quantity is direct or indirect
Other hydrobiological distributions and abundance are affected, zooplankton is closely related with Water quality.Therefore, life of swimming in the storehouse of lake is carried out
The investigation of thing simultaneously inquires into response of the plankton to change of water quality, can provide scientific basis for lake storehouse eutrophication control.
At present, we use always《Lake survey ABC》The collection net of middle recommendation, each adopts No. 25 and No. 13
Bolting silk is fabricated to independent cone collection net, is respectively used to gather phytoplankton and zooplankton, out of office using the separate mesh
During outer work, sample collector samples respectively according to the order of zooplankton after first phytoplankton, or two sample collectors can
Phytoplankton and zooplankton sample are individually gathered simultaneously, there is a problem of time-consuming or consumption manpower；In addition, can also Jing be commonly encountered compared with
Small impurities and deadwood and rotten leaf etc. cause drainage not smooth into netting gear, and increase the cleaning before the next sample of collection, significantly
Reduce collecting efficiency.
Utility model content
The purpose of this utility model is for the problems referred to above of the prior art, there is provided one kind design is simple, low cost
Plankton nets honest and clean, easy to carry, simple to operate.
To realize above-mentioned utility model purpose, this utility model employs following technical scheme：
A kind of plankton nets, including fixed mount and be fixed at least two of the fixed mount the same side and swim life
Thing net, the plankton net includes the network interface being fixed on fixed mount, the first filter screen being sleeved on network interface, is connected under network interface
The etting of side and it is connected to the sampling bottle of etting bottom；The etting top is provided with opening, and the pore size of each etting is each
Differ, for screening different types of plankton；Just the aperture of filter screen more than etting aperture, for screening out water in it is miscellaneous
Thing.
The bottom of bottle of above-mentioned sampling bottle is provided with sampling valve.
Above-mentioned fixed mount outside is connected with thief rod by fixture.
Above-mentioned fixed mount edge is connected with drawstring.
Above-mentioned just filter screen is made by bolting silk.
Above-mentioned network interface is rounded, and etting is made in inverted cone, and etting by bolting silk.
Above-mentioned fixed mount, network interface, sampling valve are made by stainless steel material.
Compared to prior art, advantage of the present utility model is：
A kind of plankton nets of offer of the present utility model, solve collection netting gear in prior art and often touch
To impurity, rubbish etc. into netting gear cause drainage not smooth the problems such as, and can simultaneously gather two kinds of plankton samples, greatly improve
Collecting efficiency.It is this utility model simple structure, easy to operate, with low cost, it is adaptable to the collection of plankton sample in the storehouse of lake,
Meet the sampling request of water environment plankton monitoring.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. fixed mount；2. network interface；3. filter screen at the beginning of；4. phytoplankton etting；5. zooplankton etting；6. sampling bottle；
7. sampling valve.
Specific embodiment
With reference to embodiments and its accompanying drawing is further non-limitingly described in detail to technical solutions of the utility model.
First, a kind of basic structure of plankton nets of the present embodiment
As shown in figure 1, a kind of plankton nets include a rectangle fixed mount 1 and to be fixed on the fixed mount same
Two plankton nets of side, the longer side outside of fixed mount 1 is connected with thief rod by fixture；Plankton net includes
The network interface 2 that is fixed on fixed mount 1, the first filter screen 3 being sleeved on network interface, the etting being connected to below network interface and it is connected to net
The sampling bottle 6 of clothing bottom, the bottom of bottle of sampling bottle 6 is provided with sampling valve 7, and sampling bottle 6 is used to collect the plankton that etting is screened
Sample；The network interface 2 is rounded, for fixing etting；The etting one is phytoplankton etting 4, and another is dynamic to swim
Thing etting 5, both of which is in inverted cone, and top is equipped with opening, and respectively by the bolting silk making that differs of pore size and
Into being respectively used to screen phytoplankton and zooplankton；Just the aperture of filter screen 3 is more than phytoplankton etting 4 and zooplankton net
The aperture of clothing 5, is made by bolting silk, for screening out the debris such as deadwood and rotten leaf；Fixed mount 1, network interface 2, sampling valve 7 are by stainless
