Abstract
The utility model discloses a netting gear for collecting a qualitative plankton sample in torrent water. The netting gear comprises a bag-shaped net, wherein the front end of the net is open; a valve is arranged at the tail end of the net; a hollow pipe clamp is arranged in the middle of the net; the net is divided into a funnel-shaped net body and a net belly which is positioned in the rear of the net body and is communicated with the net body. According to the netting gear for collecting the qualitative plankton sample in torrent water, when a plankton sample is collected in a water body at a high flow rate, the front opening can be directly arranged in the reverse water flow direction, the sample is introduced due to water impact, and enrichment is realized. According to the lower net belly, the sample collected by the net body can be collected in the net belly, so that the collected plankton sample can be prevented from taking out by counterforce of the water flow. Meanwhile, excessive screen cloth is added at the inlet of the net belly on the inner side of the pipe clamp, so that the samples entering the net belly can be effectively prevented from being taken out. The netting gear is simple in structure, practical, convenient and high-efficiency and can be widely applied to the field of plankton sample collection.
Description
Technical field
The utility model, for planktonic organism sampling field, particularly relates to a kind of netting gear for the qualitative sample collection of torrent water body planktonic organism.
Background technology
Planktonic organism sample in water body is gathered, monitors and analyzed is one of important method of monitoring water quality condition.Because planktonic organism density in part water body is less, for fully understanding plankton community composition and the structure in such water body, in the time that being done to qualitative analysis, the planktonic organism in water body often need to use netting gear to carry out enrichment.The author is engaged in water body plankton community and studies for many years, comparatively familiar to planktonic organism sample collection in the water bodys such as pond, lake, reservoir, rivers and streams.Repeatedly practice is found, need to adopt different netting gears to gather planktonic organism sample for different water bodys.The current plankton net (as shown in Figure 1) generally using is in the time carrying out the qualitative sample collection of planktonic organism to the less river water of pond, lake, reservoir and flow velocity, comparatively convenient; But, when in the very fast streams of flow velocity or rivers water body, comparatively difficult.Because in the fast water body of flow velocity, water flow impact pressure is large, be difficult to adopt and draw " ∞ " collected specimens on water body top layer, network interface can only be placed in to flow path direction collected specimens against the current.But as shown in Figure 2, flow velocity after water enters in net faster, forms counterforce with body, sample can be taken out of again, thereby cannot complete fast the collection of planktonic organism sample.
Utility model content
For addressing the above problem, the utility model provides a kind of netting gear that can complete fast the qualitative sample collection of planktonic organism in torrent water body.
The utility model solves the technical scheme that its technical matters adopts: a kind of netting gear for the qualitative sample collection of torrent water body planktonic organism, comprise bag-shaped dictyosome, the front end of dictyosome is uncovered, end is provided with valve, the middle part of dictyosome is provided with the pipe collar of hollow, and pipe collar is divided into dictyosome funnelform body and is positioned at body rear and the net tripe with body conducting.
Be further used as the improvement of technical solutions of the utility model, the inner side of pipe collar is provided with in net tripe porch can be to the clapper of opening in net tripe.
Be further used as the improvement of technical solutions of the utility model, clapper comprises the screen cloth inner outstanding to net tripe.
Be further used as the improvement of technical solutions of the utility model, pipe collar is tygon high-density tube.
The beneficial effects of the utility model: this is for the netting gear of the qualitative sample collection of torrent water body planktonic organism, in the time that flow velocity gathers planktonic organism sample in water body faster, can, directly by the uncovered front end flow path direction against the current that is placed in, allow water impact bring sample into, carry out enrichment.In the utility model, due to the existence of off line tripe, the sample of being collected can be taken in to net tripe, thereby prevent the planktonic organism sample having gathered by body, be taken out of by the counterforce of current.Meanwhile, the inner side of pipe collar is sewed and is added co-net cloth in net tripe porch, and effectively the sample of entry deterrence net tripe is led out.The utility model is simple in structure, practical and convenient, efficient, can be widely used in planktonic organism sample collection field.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the traditional qualitative sample collection netting gear of planktonic organism structural representation;
Fig. 2 is the schematic diagram that the sample of the traditional qualitative sample collection net of planktonic organism is led out by current counterforce;
Fig. 3 is the utility model example structure schematic diagram;
Fig. 4 is the schematic diagram of the utility model embodiment gather planktonic organism sample in torrent water body time.
Embodiment
With reference to Fig. 3, Fig. 4, the utility model provides a kind of netting gear for the qualitative sample collection of torrent water body planktonic organism, comprise bag-shaped dictyosome 1, the front end of dictyosome 1 is uncovered, end is provided with valve 2, the pipe collar 3(that the middle part of dictyosome 1 is provided with hollow can select tygon high-density tube), pipe collar 3 is divided into dictyosome 1 funnelform body 11 and is positioned at body 11 rears and the net tripe 12 with body 11 conductings.The inner side of pipe collar 3 is provided with in net tripe 12 porch can be to the clapper 13 of opening in net tripe 12.Clapper 13 comprises the screen cloth inner outstanding to net tripe 12.
This is for the netting gear of the qualitative sample collection of torrent water body planktonic organism, in the time that flow velocity gathers planktonic organism sample in water body faster, can directly dictyosome be put into water body, and make the uncovered flow path direction against the current that is placed in of front end, allows water impact bring sample into, carries out enrichment.The sample gathering, enters net tripe 12 along pipe collar 3, again filters, and when enrichment reaches a certain amount of, sample is put into sampling bottle through the valve 2 of net tripe 12 lower ends.In the utility model, due to the existence of off line tripe 12, the sample of being collected can be taken in to net tripe 12, thereby prevent the planktonic organism sample having gathered by body 11, be taken out of by the counterforce of current.Meanwhile, the inner side of pipe collar 3 is sewed and is added co-net cloth in net tripe 12 porch, and effectively the sample of entry deterrence net tripe 12 is led out.The utility model is simple in structure, practical and convenient, efficient, can be widely used in planktonic organism sample collection field.
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 the modification that these are equal to or replacement are all included in the application's claim limited range.
