Sampling device of sediment concentration for vertical measuring points
The invention relates to a sampling device of sediment concentration for vertical measuring points. The sampling device comprises a plurality of sampling tubes, wherein the water inlets of the sampling tubes are arranged in different heights on the same vertical line; the upper ends of the sampling tubes are fixed on a fixing device; the upper end outlet of each sampling tube is connected with an independent conduit; a valve is arranged at the part, extending out of a testing water tank, of each conduit; a bidirectional air pressure valve is connected onto the side wall of the conduit at the upper part of each valve; an independent on-line tester of sediment concentration is connected with the tail end of each conduit; a longitudinal adjusting bolt and a transversal adjusting lead screw are arranged on the fixing device. The sampling device can greatly improve accuracy and efficiency of sediment concentration sampling of multiple vertical measuring points on the same section in a model test, greatly promotes accuracy and integrity of testing data, and is of great significance.
