Description
Technical field
The present invention relates to water conservancy experimental fields, and in particular to a kind of suspended sediment layering for river model test is adopted
Sample device and the method for sampling.
Background technology
Suspended load sampler is the common sediment sampler of hydraulic engineering, currently used to have instantaneous formula and product up-to-date style two
Class.The most commonly used is horizontal type sampler in wherein instantaneous formula sampler, device body is a cylinder, and axis is parallel and water (flow) direction, two
End, which has, to be covered and spring is housed.When sampling, two lids are opened, and when waterflow stabilization, manipulating switch makes two lids simultaneously close off, and obtains instantaneous
Water sample.This sampler is easy to operate, adaptable；Time-integrating sampler has pressure regulating chamber formula, bladder, vial-type etc. several again.
Above-mentioned sediment sampler is mostly used for hydrometric cableway being the hydrometric station progress suspended load silt content sampling for testting carrier.
The pattern of suspended load sampler is various, but existing suspended load sampler all has both sides deficiency：First, one
The secondary suspended load that can only acquire the single depth of water cannot acquire the suspended load of multiple depth of waters, lead to the extension in sampling time simultaneously；The
Two, common suspended load sampler mostly build is larger, heavier, is not suitable for test operation.
Invention content
In view of the deficiencies of the prior art, it is an object of the invention to propose a kind of suspended load mud for river model test
Husky stratified sampler, and the method for sampling based on the stratified sampler must not acquire the outstanding of multiple depth of waters simultaneously with solution
The problem of moving matter, leading to the extension in sampling time.

Move the time of matter sampling.
Further, the single layer sampling structure upper and lower surface is correspondingly arranged two transverse concave grooves and matches respectively
Transverse slider, when the single layer sampling structure longitudinal overlap is combined, the transverse slider of upper layer single layer sampling structure is inserted into lower layer's list
In the transverse concave groove of layer sampling structure；Ensure the stability and globality of multilayer sampling structure.
Further, the spacing distance between neighbouring sample storehouse is equal to sampling storehouse diameter, convenient for baffle and sampling storehouse
Folding cooperation, keeps sampling more laborsaving.
Further, the spacing distance between neighbouring sample hole is equal to sampling bore dia, convenient for baffle and sampling storehouse
Folding cooperation, keeps sampling more laborsaving.
Further, distance of the cross bar away from top layer's thieff hatch peak be equal to top layer sampling storehouse minimum point away from
The distance of multilayer sampling structure top edge, when making flapper closure, thieff hatch and sampling storehouse are just spaced apart.
Further, distance of the minimum point of lowest level thieff hatch away from the baffle lower edge is equal to sampling bore dia,
Coordinate convenient for baffle and the folding in sampling storehouse, keeps sampling more laborsaving.
Further, limited block is set in the vertical groove, and the limited block samples storehouse minimum point with lowest level
In the same horizontal line, when baffle bottom end being made to be contacted with limited block, baffle just seals sampling Hatch Opening.
Further, the cross bar both ends are stretching structure, the convenient lifting or pushing cross bar in sampling operation more saves
It is power, more stable.
A kind of method of sampling based on above-mentioned stratified sampler, includes the following steps：
1) needs are sampled according to experiment, selects described point of the baffle with N number of single layer sampling structure and N-1 thieff hatch
Layer sampler；
2) stratified sampler is placed in experiment river, above carries cross bar, open front and rear baffle, make thieff hatch and sampling
Hatch Opening overlaps；
3) when waterflow stabilization, cross bar is pushed, so that front and rear baffle is simultaneously closed off, obtains instantaneous water sample.
The beneficial effects of the invention are as follows：
1, the suspended load stratified sampler that the present invention designs has the function of once sampling multilayer suspended load, substantially reduces
The time that suspended load samples in river model test.
2, the present invention can correspondingly change the number of plies of sampling according to actual conditions, and application is relatively flexible.
3, the thieff hatch on the front and rear baffle in the present invention and cylinder sampling Hatch Opening use arranged for interval, can make sampling more
Add laborsaving.
