Description
Technical field
The utility model relates to a kind of collector, especially relates to a kind of planktonic novel layering collector that is used to gather.
Background technology
From first rich the writing after " lake survey ABC " publish of admiring of hydrobiont research institute of (1956) Chinese Academy of Sciences of liberation, the p. qualitative collection net of being recommended is used till today always, it is to adopt No. 25, No. 13 bolting silks to be made into the conical net of gathering, and the about 20cm of bore is about 60cm; The former is used to gather phytoplankton, and the latter is used to gather animal plankton.Quantitative collector has multiple modified on the basis of circular sampling bottle (using the water chemistry sampling bottle), early stage a kind of should the use in the waters that is no more than depth of water 10m, it is a kind of self-control water bottle, then use another kind of Lu Tenieer sounding bottle at the deep water place, but because that it adopts the water yield is limited, rare place is difficult to collect the strong large-scale kind of swimming ability in p. density.In recent years the sounding bottle capacity of Chinese Academy of Sciences hydrobiont Research Institute expands the hydrophore (principle is with the Lu Tenieer type) of once adopting five liters in water to; Though capacity has enlarged, because whether water inlet little (diameter 6cm) can be gathered most kinds and still send one's regards to topic.A water layer point needs to gather water sample four times (20 liters) when the reservoir sampling operation, does quantitative test after the filtration; It is too much to adopt the waterside number, and the cost labour is too big.Japan's Biwa Lake uses a kind of long tube type collector, the hydrophore that organic glass is made, and also because of caliber is little, capacity is little, can only gather top layer 2m water sample, can't use at the deep water place.
The plankton net style of using in the ocean is a lot, and performance also has nothing in common with each other, and using always has taper and all moral formula two classes.Its medium-and-large-sized net is used for qualitative collection, and medium and small all moral formulas are applicable to water-bed certainly to top layer vertical demixing collection, do the quantitative test sampling.
When gathering a certain water layer water sample, use dead lock, steel wire, heavyly hang down (5-10kg), corresponding devices such as locking rope.After determining to gather water layer network interface is put into the water layer lower limit, slowly is pulled upwardly to the water layer upper limit then, the sinker that will go here and there on steel wire puts down immediately, make it beat dead lock, make the subordinate that hammers into shape of net hang down and to cover network interface, net no longer network access of outer water, again after netting the hauling-out water surface, the water sample that bottom tube is collected is exactly the concentrated water sample of this water column, can be used for qualitative analysis, also have a kind of reversing water sampler, though but stratified sampling, but also because of capacity is too little, institute's water sampling lacks representativeness.
Summary of the invention
The utility model mainly is that the water inlet of solution existing in prior technology is young, and the technical matters of the little grade of volume provides a kind of water inlet big, the novel layering planktonic organism collector that volume capacity is big.
The utility model also solves the existing in prior technology complex structure simultaneously, uses inconvenience, and the technical matters of the big grade of operation easier provides a kind of simple in structure, easy to use, operates light and handy novel layering planktonic organism collector.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of novel layering planktonic organism collector, it is made up of netting gear portion, water collecting part and water entering section, water entering section and water collecting part are arranged at a side of netting gear respectively, and are that described water entering section is a net gate structure.

As preferably, described handle is provided with pull bar, and it is arranged on the handle cross bar, and pull bar one end is provided with " U " type snap close, and the pull bar other end is provided with traction rope.
As preferably, described netting gear portion is made up of connecting portion, buffer part and filter house, and buffer part is arranged between connecting portion and the filter house, and last connecting portion is connected with the sheetmetal circle, and following connecting portion is arranged on the screen pack.
As preferably, described water collecting part is made up of water collect tank and rising pipe, and water collect tank is arranged at down on the connecting portion, and rising pipe is arranged on the water collect tank, and the rising pipe exit is provided with rubber stopper.
As preferably, described buffer part is tapered, and screen pack is back taper, and screen pack is connected with buffer part diameter maximum.
As preferably, the network interface diameter of described water entering section is 37cm, and a semicircle net door diameter is 40cm; The high 27cm of described handle, wide 40cm, thick 0.3cm, handle is provided with the rope that indicates size; Described " U " type snap close is that copper sheet or the stainless steel of 0.2-0.3cm formed by thickness.
As preferably, described to go up connecting portion be long 10cm, up and down diameter 37.5cm cylindricality; Described connecting portion down is long 10cm, diameter 6.2cm cylindricality; Described buffer part is long 20cm, and back cut diameter 37.5cm, lower port diameter are 50cm; Described screen pack is long 70cm, back cut diameter 50cm, lower port diameter 6.2cm.
As preferably, described water collect tank is infundibulate, and length is 14cm; Described rising pipe is long 4cm, the cylindricality of internal diameter 2cm.
Therefore, the utlity model has rational in infrastructure, modern design, simple in structure, easy to use, operation is light and handy, sampling quantity reaches characteristics such as superior performance greatly, especially provides a kind of novel layering planktonic organism collector for planktonic collection.
