Abstract

The invention relates to a sampling device for flowing water bodies, the device effectively solves the problems that manual sampling is inconvenient, automatic sampling cannot fully reflect the actualsituation of the water bodies and sampling is not accurate enough. The technical scheme includes driving an impeller to rotate through river water; driving, by the impeller, a first winding wheel tocollect a rope, and releasing, by a second winding wheel, the rope, so as to enable the time interval for collecting samples to be proportional to the flow rate of the river water; controlling the starting and stopping of a motor by a signal transmitted by a Hall sensor; when the motor drives a second rotary shaft to rotate, collecting a sample; collecting, by the second winding wheel, the rope, and releasing, by the first winding wheel, the rope, so as to enable the impeller to rotate in the reverse direction. According to the above technical scheme, the nearby river water is stirred to prevent the river water from stratification, and floating objects wound on the impeller are automatically separated from the impeller.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sampling device for flowing water bodies. Background technique [0002] In order to control the water quality of the river, it is necessary to sample the river water body at regular intervals. The sampling frequency is evenly distributed in different periods and different flows according to the change of the water regime. There are two methods of manual sampling and automatic sampling. Manual sampling is a waste of time and energy, and it is not convenient to sample at night; The time interval should be adjusted in time; the water quality stratification may occur in a certain section of the river, and the automatic sampling device can only sample the water layer where the sampling port is located, which cannot fully reflect the real situation of the water body; There are some floating objects such as aquatic plants, and some automatic sampling devices powered by impellers are e...
