Wastewater sampling device

Abstract

The utility model belongs to the technical field of wastewater treatment, and particularly relates to a wastewater sampling device which comprises a box body, a wastewater input pipe, a detection output pipe, a wastewater output pipe and a flow guide pipe connected with the wastewater input pipe, and further comprises a gravity driving assembly used for driving the flow guide pipe to switch positions under the action of gravity, the switching assembly is connected with the gravity driving assembly and is used for controlling the flow guide pipe to move, so that the flow guide pipe is respectively aligned with the detection output pipe and the wastewater output pipe; the magnetic sealing assembly is arranged at the end part of the flow guide pipe and inlets of the detection output pipe and the wastewater output pipe, and realizes sealed connection through magnetic attraction force; the liquid discharging assembly is arranged at the bottom of the box body and used for discharging waste water in the box body, the position switching of the flow guide pipe without external energy can be realized, and the energy consumption is reduced; the magnetic sealing assembly ensures the sealing performance when the flow guide pipe is connected with the output pipe through the magnetic attraction force of a permanent magnet ring and a ferromagnetic sealing groove.
