Automatic water sample collecting device for rainwater inspection well

Abstract

The invention relates to an automatic water sample collecting device for a rainwater inspection well. The automatic water sample collecting device for the rainwater inspection well can be used for automatically collecting a water sample in a rainwater pipeline in a catchment basin, and consists of baffle plates, a shaft-end pressing plate, a rotary shaft, a key, an outer vertical column, second baffle plates, a thrust ball bearing, a travel switch, a fixed collision block, a speed reducer, a direct current motor, a storage battery, a bottom plate, a third baffle plate, a bracket, a pipeline, a pipeline bracket, a rotary table, a cup base, a lifting lug, a side plate, a top plate, a telescopic rod bracket, a telescopic rod, a floating ball valve, a water pump and a weir height adjustable water collector. The automatic water sample collecting device is applicable to sampling of rainwater runoff collected by the rainwater inspection well in various underlying surface types, is matched with the inspection well, and meets a sampling requirement for research on non-point source pollution to a large extent.

Description

technical field [0001] The invention belongs to the technical fields of municipal engineering and environmental protection, and in particular relates to an automatic collection device for rainwater inspection well water samples. Background technique [0002] With the global climate change and the rapid development of urban construction, the production and confluence conditions of built-up areas have changed greatly, the complexity of the underlying surface has increased, the emission of atmospheric smoke and dust has increased, and the traffic volume has increased. In the rainwater runoff formed by rainfall, nearly Various substances in ground air and urban surface mainly contain pollutants such as chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), suspended solids (SS) and various heavy metals. The initial rainwater enters the rainwater collection pipe network through confluence. It is necessary to collect the rainwater in the rainwater pipe network ...
