| description | The utility model provides an image acquisition device for bed load sediment transport rate measurement, and belongs to the field of water conservancy and landform measurement. Comprising a water tank which contains refractive index matching liquid and transparent spherical particles used for simulating moving pebbles in a river channel and divides the water tank into an upstream section, a monitoring section and a downstream section; the liftable baffle comprises a top plate arranged on the side wall of the water tank at the inlet of the monitoring section and a baffle in threaded connection with the top plate, and bubbles possibly existing on the surface of the refractive index matching liquid are prevented from entering the monitoring section by adjusting the depth of the baffle immersed into the refractive index matching liquid of the upstream section; the laser light source is arranged on one side of the water tank of the monitoring section and is used for forming a laser lighting plane area in the monit |
