Abstract

The invention discloses a large-entrance load accurate testing device suitable for medium and small rivers. The large-entrance load accurate testing device comprises a large-entrance load sampler, a bed load calibrator and a shipborne linkage support. The beneficial effects of the invention are that: the method is suitable for large-scale production; the window and the door of the sampler can be closed by small external force; when the flow velocity is high, the dead weight of the instrument is increased, the stability of the instrument in a riverbed is kept, the sampling is true and reliable,an entrance door is completely fitted with the riverbed, the disturbance effect on water and sand is reduced, obvious scouring or silting is not generated in front of the entrance door, and the authenticity of bed load sampling is ensured.

Description

technical field [0001] The invention relates to a test device, in particular to an accurate test device suitable for large mouth gates of small and medium-sized rivers, and belongs to the technical field of hydrological sediment test sample sampling equipment. Background technique [0002] Sediment movement and scouring deposition are important hydrological phenomena in rivers, because sediment has a great influence on river hydrological regime, river development and river bed evolution. Displacement sediment movement is another basic form of river sediment transport. The quantity of moving sediment is generally less than that of suspended sediment. However, in some upstream mountainous rivers, the quality and quantity of the flow are often very large. Due to the relatively coarse particles of moving sediment, it often silts up reservoirs, irrigation canals and river courses, and is not easy to wash away, which has a great impact on the management and utilization of water ...
