Abstract

The invention provides a full-automatic sampling device for roof runoff in different time periods. The full-automatic sampling device comprises a sampler box body, a shading device and a rainwater sensor which are located above the sampler box body, and a turntable type automatic sampling device and an electric control box which are located in the sampler box body. The full-automatic sampling device can automatically collect a roof runoff sample and record the sampling time of the roof runoff sample, and has the advantages of light weight, easiness in carrying, simplicity in operation and capability of improving the experiment accuracy.

Description

technical field [0001] The invention relates to the technical field of runoff sampling devices, in particular to a fully automatic roof runoff sampling device in time intervals. Background technique [0002] The roof runoff sampling device is an important experimental device for studying the characteristics of urban non-point source pollution, revealing the output law of roof accumulated pollutants driven by heavy rain, and analyzing the impact mechanism of different rainfall characteristics on roof runoff water quality characteristics, etc. . At present, the mainstream roof runoff time-sampling devices are complex in structure, relatively expensive, and the number of samples is small, which is not conducive to the study of rainfall events with a long duration of rainfall. Due to limited funds, many projects failed to support the purchase of this device. Researchers can only hire workers to sample roof runoff at different times during heavy rains. This is not only time-cons...
