Embodiment 1

[0033] In this example, if Figure 1-7 As shown, a layered sampler for suspended sediment used in river engineering model tests includes three single-layer sampling structures 1, baffles 3 and crossbars 2; the single-layer sampling structure 1 is cylindrical in the middle The cuboid structure of the sampling chamber 11 has vertical grooves 12 arranged on the vertical edges of its front and rear end faces; the single-layer sampling structure 1 is vertically overlapped and combined to form a multi-layer sampling structure; the baffle plate 3 is composed of a base plate 31, two The perforated plate 32 and two non-perforated plates 33 are sequentially spliced ​​at intervals; the perforated plate 32 is provided with a circular sampling hole 321 having the same diameter as the mouth of the sampling chamber 11; the baffle plate 3 is closely attached to the multi-layer The front and rear end faces of the sampling structure are placed in the vertical groove 12; the upper ends of the fr...

Embodiment 2

[0043] In this example, if Figure 1-7 Shown, a kind of sampling method based on above-mentioned layered sampler, comprises the following steps:

[0044] 1) according to test sampling needs, select the described stratified sampler with the baffle plate 3 of 3 single-layer sampling structures 1 and 2 sampling holes;

[0045] 2) Place the layered sampler in the test river, lift the crossbar 2, open the front and rear baffles 3, and make the sampling hole 321 coincide with the sampling chamber 11;

[0046] 3) When the water flow is stable, press down the crossbar 2 to close the front and rear baffles 3 at the same time to obtain an instant water sample.

[0047] The present invention will be further described below in conjunction with a specific example.

[0048] The shape and structure of the sampler used for sampling in this embodiment are as follows: Figure 1-7 As shown, it is a three-layer suspended mass sampler. During the test, a bed of natural sand was laid according ...

Abstract

The invention discloses a suspended load sediment stratified sampler for a river model test, the suspended load sediment stratified sampler comprises a plurality of single-layer sampling structures, baffles and cross bars, wherein each single-layer sampling structure is a rectangular parallelepiped structure in which a cylindrical sampling chamber is arranged in the middle, the single-layer sampling structures are vertically overlapped and combined into a multi-layer sampling structure, perforated plates are provided with circular sampling holes having a diameter same as that of openings of sampling bins, the number of the sampling holes of the baffles is one less than that of the sampling bins, the upper ends of the front and rear baffles are connected by the cross bars; the invention also discloses a sampling method based on the suspended load sediment stratified sampler, and the sampling method can be used for sampling of a plurality of suspended loads in one time, and greatly shortens the sampling time for the suspended loads in the river model test.

Description

technical field [0001] The invention relates to the field of water conservancy experiments, in particular to a layered sampler for suspended sediment and a sampling method for river engineering model tests. Background technique [0002] Suspended mass sampler is a commonly used sediment sampler in water conservancy projects. At present, there are two types of instantaneous type and time-integrated type. Among them, the most commonly used instantaneous sampler is the horizontal sampler. The body is a cylinder, the axis is parallel to the direction of water flow, and there are covers and springs at both ends. When sampling, the two covers are opened, and when the water flow is stable, the switch is operated to close the two covers at the same time to obtain instantaneous water samples. This kind of sampler is easy to operate and has strong adaptability; there are several types of time-integrated samplers, such as pressure-regulating chamber type, leather bag type, and bottle ...
