Problems solved by technology
[0003] Purpose of the invention: The technical problem to be solved by the present invention is the automatic sampling of rainwater equal-volume segmental water quality analysis, which overcomes the defects of manual operation in the rain and the inability to ensure equal-volume segmental sampling in the existing rainwater quality analysis sampling process, and improves the rainwater isovolumic segmental sampling process. The efficiency and accuracy of collecting sampling saves manpower and material resources, and provides a reliable technical basis for scientifically determining the initial rainwater abandonment flow

The invention discloses an automatic sampling device for isovolumetric segmented rainwater quality analysis, and belongs to the technical field of rainwater runoff pollution monitoring and water environment protection. The automatic sampling device for isovolumetric segmented rainwater quality analysis comprises a conversion joint, sampling bottles, floating balls, threaded joints, rubber pipes, adrain pipe, batteries, floating blocks, electrodes, sliding rails, conductive electrode sheets, electromagnetic coils, shunt pipes, turnover gates, rotating shafts, magnets, floating boxes, clampinggrooves, a square communicating pipe, water collecting tanks, a rainwater inlet and an overflow pipe. During rainfall, rainwater runoff enters the water collecting tanks through the rainwater inlet, when the amount of rainwater exceeds the designed constant volume of the water collecting tanks, the turnover gates are closed under the action of buoyancy and magnetic force, and then rainwater entersthe sampling bottles through the shunt pipes. The rainwater inlet can be connected with a rainwater collector, a building roof rainwater drop pipe or a road rainwater pipe network inlet, sampling requirement of atmospheric precipitation, roof rainwater and road surface rainwater is met, and the application prospect is broad.
Description
technical field [0001] The invention relates to the technical fields of rainwater runoff pollution monitoring and water environment protection, in particular to an automatic sampling device for isovolumic and segmented water quality analysis of rainwater. Background technique [0002] Since the reform and opening up, with the acceleration of urbanization, the area of impermeable surface has been increasing, flood disasters have become more frequent, urban rainwater runoff pollution and the utilization of rainwater resources have attracted more and more attention. Due to the accumulation of pollutants and the scouring effect of rainwater, the concentration of pollutants in the initial rainwater is relatively high, but the current surface runoff and roof rainwater are directly discharged into the municipal pipe network, resulting in a large pollution load of the municipal pipe network and sewage treatment plants. Whenever there is a heavy rain, the flood discharge capacity o...
