AI Technical Summary
Existing wastewater testing and sampling devices are prone to clogging of the collection port due to the accumulation of pollutants in wastewater, especially when the flow rate is slow or there are stagnant areas, which can lead to sampling failure.
A wastewater sampling device was designed, comprising a liquid inlet assembly consisting of a sealing rubber ring, a limiting block, a fixing ring, a T-shaped rotating block, and a brush. The fixed column is driven to rotate by the friction of the sealing rubber ring and the buoyancy of the float, which in turn drives the brush to clean the filter ring holes and prevent blockage when liquid flows in.
It effectively prevents clogging on the filter ring, ensures the continuity and accuracy of the sampling process, and avoids sampling failure.
