Description
Technical field:
The utility model relates to the equipment that carries out vertical measuring point sampling in a kind of muddy water flume test, particularly a kind of vertical multi-measuring point silt content sample devices.
Background technology:
Suspended sediment in natural river is nonuniform sediment, and silt content is the immediate cause of riverbed erosion and deposition with the adjustment that grain is joined vertical line distribution.Therefore, silt content joins with grain the key point that vertical line distribution is suspended sediment bypassing research.Join the interaction relationship between vertical line distribution and riverbed erosion and deposition in order to study silt content and grain, need to carry out meticulous flume test, for the accuracy of warranty test, this just needs the sample gathering with the vertical multiple measuring points of section in enormous quantities at the trial, and will process timely these large batch of samples.And existing sampler and sampling method all cannot meet above-mentioned requirements, cause test findings not accurate enough.
Utility model content:
The purpose of this utility model is to be difficult to meet the requirements of problem for the vertical silt content sampling precision of silt carrying flow in test, design a kind of principle simple, the vertical measuring point silt content sample devices of easy operating, can realize same vertical section multi-measuring point and sample simultaneously.The technical solution of the utility model:
A kind of vertical measuring point silt content sample devices, comprise many stopple coupons, described stopple coupon internal diameter is 4mm, and the water inlet of many described stopple coupons is arranged on the differing heights of same vertical straight line, and the vertical range between the water inlet of every described stopple coupon is 1cm-2cm; The upper end of every described stopple coupon is fixed in a stationary installation, the upper end outlet of every described stopple coupon all connects an independently conduit, described catheter diameter is 4mm, the part that every described conduit extends to outside experimental tank is provided with a valve, is connected with a positive and negative Bidirectional gas pressure valve on the duct wall above each described valve; The tail end of every described conduit is connected with an independently online silt content tester, and the outlet of described every conduit connects water-break pond; Described stationary installation is arranged on the guide rail parallel with described experimental tank, and described stationary installation is provided with longitudinal adjustment bolt and horizontal adjusting screw.
Sample devices of the present utility model, can make silt content in model test greatly improve with precision and the efficiency of the vertical multi-measuring point sampling of section, to test figure accurately there is great facilitation with improving, therefore meaning is huge.
Brief description of the drawings:

The stopple coupon partial structurtes detail drawing (left side is side view, and the right is the front elevation along water (flow) direction) of Fig. 2, sample devices of the present utility model.
In figure, 1 is that stopple coupon, 2 is that conduit, 3 is that positive and negative Bidirectional gas pressure valve, 4 is that valve, 5 is that stationary installation, 6 is that online silt content tester, 7 is that water-break pond, 8 is experimental tank.
Embodiment:
Below in conjunction with drawings and Examples, the utility model is elaborated.
As depicted in figs. 1 and 2, vertical measuring point silt content sample devices of the present utility model, comprises many stopple coupons 1, and described stopple coupon 1 is the stainless-steel tube that internal diameter is 4mm.On the interior section that needs sampling of experimental tank 8, select a vertical line, the silt content sampling measuring point of multiple different depths can be set on each vertical line, the concrete number of sampling measuring point, determine according to the concrete depth of water, between two measuring points, depth difference is 1cm～2cm, and measuring point can reach at most dozens of, and each measuring point all connects independently stopple coupon 1.Like this, many described stopple coupon 1 Parallel to the flow direction are arranged in a row, and the water inlet of all stopple coupons 1 is arranged on the differing heights of same vertical straight line.Stretch out after the water surface upper end of every described stopple coupon 1, all be fixed in a stationary installation 5, the upper end outlet of every described stopple coupon 1 all connects an independently conduit 2, the flexible pipe that described conduit 2 is 4mm for internal diameter, every described conduit 2 extends to after experimental tank 8, respectively connects a valve 4, is connected with a positive and negative Bidirectional gas pressure valve 3 on conduit 2 sidewalls above each described valve 4, between this positive and negative Bidirectional gas pressure valve 3 and conduit 2 sidewalls, be also provided with a valve 4.The tail end of every described conduit 2 is connected with an independently online silt content tester 6, can measure in real time the sample of each measuring point independently, ensure between large Lot sample without numbering, without preservation, take-and-measure, has ensured accuracy and promptness.The outlet of described every conduit 2 is connected in a water-break pond 7.Described stationary installation 5 is arranged on the guide rail parallel with described experimental tank 8, can move along tank bearing of trend.Described stationary installation 5 is provided with longitudinal adjustment bolt and horizontal adjusting screw (in figure for illustrating), longitudinally adjusting bolt can finely tune up and down, adapting to because of Sediment Siltation, wash away the riverbed causing changes, laterally adjusting screw can carry out larger lateral separation adjustment, and sample devices of the present utility model can be sampled on each different vertical line of a transversal section.
Sampling equipment of the present utility model, is self-priming collection muddy water sample when equipment is normally worked, and positive and negative Bidirectional gas pressure valve 3 is suitable in the time of initial sampling, extract muddy water by it, realize self-priming, in addition, in the time of stopple coupon 1 silting, can eliminate by inflation, and on every conduit 2, be all provided with independent positive and negative Bidirectional gas pressure valve 3, to wherein one while clearing up silting, do not affect other normal sampling, compare with cleaning method with existing cleaning equipment, there is very large advantage.
In process of the test, no longer sample for be embedded in bed surface measuring point once because of channel aggradation, and when channel scour is in the time that this exposes bed surface, can eliminate by positive and negative Bidirectional gas pressure valve 3 inflations the silting of corresponding sample pipe 1 then task.
The utility model has solved the vertical fixed point silt content of the section difficult problem of sampling, adopt the utility model can collect accurately the silt content sample of the vertical multi-measuring point of same section, and principle is simple, practical, easy to operate, there is higher practical value to measuring the vertical fixed point silt content of section in test.
