As the preferred version of this programme, following improvement can be had:
In more excellent scheme: described stifled ball is made up of the material of density slightly larger than seawater.
In more excellent scheme: described stifled ball is solid rubber ball.
In more excellent scheme: the diameter ratio of the diameter of described stifled ball and described narrow diameter section point is 7:5, the diameter ratio of the diameter of described stifled ball and described wide diameter part point is 7:10.
In more excellent scheme: the internal diameter of the corresponding described acquisition port of described cam member is arranged.
In more excellent scheme: described wide diameter part divides the diameter ratio divided with described narrow diameter section to be set to 2:1.
In more excellent scheme: the length of described sampling pipe is set to 1 to 3 meter.
Compared to prior art, the technical solution of the utility model possesses following beneficial effect:
Sampling pipe in the utility model adopts PVC material to make, cost is low and corrosion-resistant, sampling pipe is marked with length scale, make the degree of depth can knowing sampling when sampling, sampling apparatus is provided with the sampling joint with cam structure and stifled ball simultaneously, thus can carry out easily sampling and setting-out, there is the simple and advantage of convenient sampling of structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model critical piece.
Embodiment
In order to make the utility model object, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further details.
The wherein structural representation of Fig. 1 the utility model critical piece, as shown in Figure 1, the utility model is the full water layer sampling apparatus of a kind of Ruditapes philippinarum nursery floating larvae, comprises sampling pipe 10, is separately positioned on the sampling joint 20 at sampling pipe 10 two ends and capping plug 30, stifled ball 50.Sampling pipe 10 is marked with scale 11, sampling joint 20 comprise wide diameter part divide 21 and narrow diameter section divide 22, wide diameter part divide 21 and narrow diameter section divide 22 between form tapering transition 23, narrow diameter section divides one end of 22 to be provided with acquisition port 221, acquisition port 221 place is provided with cam member 40, and the internal diameter of the corresponding acquisition port 221 of cam member 40 is arranged.Cam member 40 is provided with lug boss 41 and water inlet gap (not shown), the side of cam member 40 is also provided with steering control level 42, be exposed at outside acquisition port 221 outside steering control level 42, by rotate steering control level 42 can control lug boss 41 towards, lug boss 41 upward time, stifled ball 50 and narrow diameter section points 22 mouthfuls has gap, lug boss 41 down time, stifled ball 50 and narrow diameter section point 22 mouthfuls of gaplesss.Stifled ball 50 is arranged in the cavity that wide diameter part points 21 and cam member 40 surround.
In preferred embodiment, the length of sampling pipe 10 is set to 2 meters, wide diameter part divide 21 and narrow diameter section divide the diameter of 22 to be set to 50mm and 25mm respectively, the diameter of stifled ball 50 is set to 35mm, the diameter of sampling pipe 10 is set to 50mm, and the diameter in water inlet gap is set to 15mm.
During sampling, lug boss 41 first on confirmation cam member 40 is in the side back to stifled ball 50, then one end sampling pipe 10 being connected to sampling joint 20 extend into downwards in the water surface, stifled ball 50 upwards departs from acquisition port 221 under the effect of deep water pressure, makes water sample flow into the body of sampling pipe 10 from water inlet gap; When sampling pipe 10 is extracted out from the water surface, stifled ball 50 falls back to acquisition port 221 thus blocks into water gap under the effect of gravity and water pressure, the water sample in sampling pipe 10 is now prepared to shift, when wanting setting-out to specified containers (not shown), rotate steering control level 42 lug boss 41 on cam member 40 to be turned to just stifled ball 50 jack-up is made to there is gap between stifled ball 50 and acquisition port 221 to the side of stifled ball 50, the water sample now adopted flows in specified containers from sampling pipe 10, completes a sampling action in desired depth region.
Different water levels in flower clam floating larvae uneven distribution great Chi, can carry out according to great Chi shape sampling of layouting during sampling, generally can establish 30-40 point, the sample water that each sampling pipe 10 gathers can return laboratory observation with barreled, then just can science accurately estimate when smallpox clam floating larvae quantity according to the unit of water body floating larvae quantity of each point and the total water body amount of sample range.
In sum, this Ruditapes philippinarum nursery floating larvae full water layer sampling arrangement samples pipe 10 adopts PVC material to make, cost is low and corrosion-resistant, sampling pipe 10 is marked with length scale 11, make the degree of depth can knowing sampling when sampling, this sampling apparatus is provided with the sampling joint 20 with cam structure 40 and stifled ball 50 simultaneously, thus can carries out easily sampling and setting-out, there is the simple and advantage of convenient sampling of structure.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
