The utility model has the advantages of simple construction, low cost and convenient operation, portability, practical and accurate sampling, easy popularization, slight interference with the pond bed mud when sampling. The specified depth of bed mud of culture pond can be collected completely in original state on the specified site for studying the character of the bed mud. The utility model can still be used in columnar shaped sampling from other shallow water deposition.
Description
Technical field
The utility model belongs to a kind of water body deposit sampling thief, is specifically related to be used for sediment of pond cylindrical sample collector.
Background technology
Sediment of pond is a very important ingredient in the pond ecosystem, occur in the chemistry and biology process influence pond water quality and the cultured output of sediment of pond, therefore the research to sediment of pond character helps aquaculture management, thereby raising cultured output, yet in China the research of sediment of pond still is in the starting stage, does not also have a kind of suitable sediment of pond sample collecting device.At present, big water body deposit such as rivers,lakes and seas generally adopts freshwater mussel formula bottom sampler or gravity sampling thief, the general complex structure of these sampling thiefs, build is big and heavy, bigger during sampling to interfacial disturbance, and drop point and sampling depth are inaccurate, are not suitable for this little water body bed mud sample collecting in pond.
Summary of the invention
For addressing the above problem, the utility model purpose is to provide a kind of sediment of pond columnar sampler, and it is little to the sediment of pond disturbance, can adopt the bottom mud column-shaped sample of cultivating pool complete, original state on set point and the set depth.
The utility model purpose is achieved in that a kind of sediment of pond columnar sampler, it is characterized in that: include the handle, water-inflow and drain valve, stopple coupon and the drill bit that are linked in sequence, wherein water-inflow and drain valve comprises the valve pocket that has the Inlet and outlet water through hole and is located at the pressure that utilizes water of stopple coupon upper end and the gravity nonreturn valve core of folding voluntarily.
Described nonreturn valve core is made up of O-ring seal that has small opening and the weight member that can close the O-ring seal small opening.
Described weight member is the gravity steel ball, and the small opening top of O-ring seal is the spherical crown shape, size and gravity steel ball coupling.
Described stopple coupon includes detachable inner sleeve and outer tube.
The utility model is simple in structure, easy to carry, with low cost, operate simple and easyly, sampling is practical, accurately, easily promotes, little during sampling to the sediment of pond disturbance, can adopt the cylindrical sample of the complete cultivating pool bed mud that maintains the original state of set point and set depth, thereby help research to sediment of pond character, the utility model also can be applicable to other shallow water body sediment cylindrical sample collections.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model purpose is achieved in that a kind of sediment of pond columnar sampler, includes the handle 10, water-inflow and drain valve, stopple coupon and the drill bit 1 that are linked in sequence.
Water-inflow and drain valve is connected in handle 10 belows by web member 9, comprises valve pocket 5 and nonreturn valve core.Valve pocket 5 middle and upper part symmetries have two Inlet and outlet water through holes 8.The nonreturn valve core position is lower than the height of Inlet and outlet water through hole 8, is located at the stopple coupon upper end, can utilize the folding voluntarily of hydraulic pressure and gravity.Nonreturn valve core is made up of O-ring seal 7 that has small opening 14 and the weight member 6 that can close O-ring seal 7 small openings 14.Weight member is a gravity steel ball 6, and small opening 14 tops of O-ring seal 7 are the spherical crown shape, size and gravity steel ball 6 couplings.
Stopple coupon is connected in the water-inflow and drain valve below, includes detachable inner sleeve 4 and outer tube 3.Outer tube 3 is connected with drill bit 1 with the valve pocket 5 of water-inflow and drain valve respectively.Inner sleeve 4 is a pvc pipe, is marked with to be convenient to distinguish sample layer time sign 13, for example " on " sign, D score sign.O-ring seal small opening 14 bottoms of water-inflow and drain valve are cylindric, internal diameter and stopple coupon inner sleeve 4 external diameters coupling, socket sealing just.The stopple coupon of existing sampler is a mono-layer tube, must immediately the mud sample be taken out from stopple coupon after each sampling, carry out next sampling work after the cleaning again, very bother, and the mud sample is after the stopple coupon taking-up, owing to lose the styling of stopple coupon, rupture its destroy integrity in transit easily what get back to the research place from sampling spot.And stopple coupon is made up of inner sleeve 4 and outer tube 3 in the utility model, the inner sleeve 4 whole taking-ups that the mud sample will be housed after each sampling place, and replace with new inner sleeve 4, thereby can run continuous samples easily, the integrality of sample is maintained, and sample clear layer up and down is difficult for obscuring.
Drill bit 1 spins with the stopple coupon lower end, and the end that itself and stopple coupon join is provided with the closed level 2 with inner sleeve 4 size couplings.Angle between drill bit 1 lateral surface and the slotting face is at the 45-70 degree, and the best 60 degree angles that are are more laborsaving when sampling like this, especially in the harder place of bed mud, and the smooth insertion when being convenient to take a sample.
When using the utility model sediment of pond columnar sampler, at first gravity steel ball 6 is positioned in the O-ring seal 7 small opening spherical crowns of valve pocket 5 of water-inflow and drain valve, web member 9 is connected with valve pocket 5 and comes off with preventing gravity steel ball 6, press after stopple coupon outer tube 3 is connected with web member 9 " on ", D score sign 13 places stopple coupon inner sleeve 4 in the outer tube 3, and inner sleeve 4 upper ends are embedded in small opening 14 lower ends of O-ring seal 7, screw on drill bit 1, inner sleeve 4 is fixed between closed level 2 and the O-ring seal 7, select the length of handle 10 then according to water depth and sampling depth, one meter of every section handle segment length in the present embodiment for example, on plugging into screw thread connecting parts 11, following two sections handle sections form two meters long handles.
After installing, the alignment settings stopple coupon of naming a person for a particular job vertically inserts water body lentamente, when drill bit 1 touches water and bed mud interface, read the reading a (depth of water) of the water surface on handle 10, continue downwards evenly firmly, when the water surface, stops downwards firmly during just for set depth (reaching sampling depth) in the difference of handle reading b and a.Insert in the whole process of water body and bed mud at stopple coupon, along with water enters in the stopple coupon, the pipe internal pressure increases gradually, and gravity steel ball 6 finally backs down, originally the gas in the stopple coupon is discharged from the Inlet and outlet water through hole 8 of valve pocket 5, and water and bed mud enter stopple coupon smoothly until reaching sampling depth.After stopping firmly, gravity shot 6 is return under the effect of gravity and water body pressure, closes the small opening 14 of nonreturn valve core O-ring seal 7, makes sample come off thereby make stopple coupon upper end sealing blocking-up water enter stopple coupon.Stop downwards firmly back about 5 seconds, carry sampling thief on lentamente, the water in the water-inflow and drain valve is discharged from Inlet and outlet water through hole 8.During sampling, screw off drill bit 1, take off and have inner sleeve 4 complete, original state bed mud sample, change another clean inner sleeve and continue to gather other set point samples.
After all samples is taken back sensing chamber, can pass through the matching used branch sample jacking device of forming by push rod 15 and pushing tow face 16, sample is upwards released from inner sleeve 4 lower ends, can be according to the research needs with the sample layering.After cleaning up, inner sleeve 4 behind the release sample can be recycled.
