Description
Technical Field
[0001] The utility model belongs to the technical field of river channel sampling, and in particular relates to a river channel sediment sampling device. Background Art
[0002] Garbage and waste sink to the bottom of the river channel and stay at the bottom of the river channel to form river channel sediments. In order to study the accumulation, distribution, transformation and migration of pollutants discharged into the water body on the riverbed, sediment samples need to be collected. When sampling river channel sediments, samples of river channel bottom mud in designated areas will also be collected. The operator operates the collector that sinks to the riverbed to enter the riverbed and collect river channel bottom mud. However, garbage, waste and other sediments in the river channel sink to different areas on the riverbed. When the collector moves into the riverbed to collect river channel bottom mud, the sediments sunk in the collection area will block the collector. Some sediments will also follow and block the collection port area of the collector while the collector sinks. It is not possible for the operator to flexibly and conveniently perform sediment separation and blocking operations during the sinking of the collector, which is not conducive to the operator operating the collector to sink to the inside of the riverbed to collect river channel bottom mud, affecting the collection effect and operation efficiency.
