The utility model relates to a hierarchical sampling system of little plastics of portable normal position water has inlayed the water inlet above the sampling frame lateral wall, the water inlet passes through solenoid valve intercommunication filtering mechanism, its output intercommunication delivery port, the delivery port inlays in sampling frame lateral wall below, sets up the suction pump between delivery port and filtering mechanism, in sampling frame's inside, and set up level sensor on the same water flat line of water inlet, level sensor connects the data collection and control ware, set up the flowmeter between solenoid valve and filter equipment, the data collection and control ware is connected to the flowmeter, and solenoid valve and suction pump are connected to the data collection and control ware, control solenoid valve and suction pump according to flow volume signal and liquid level altitude signal. The utility model discloses can preset sampling depth, the samplingvolume isoparametric realizes the full automatic acquisition of little plastics, but also manual control gathers the process, the state of collection under water of real time monitoring sample realizes that the precise and quantitative of the little plastics sample of water gathers.
