Automatic sampling device for sewage detection

Abstract

The invention discloses an automatic sampling device for sewage detection. The automatic sampling device comprises a base, a moving mechanism, a placing disc, a water pump and a motor base. The movingmechanism is fixed on the base, the upper surface of the placing disc is connected with at least four groups of sampling cups through a fixing mechanism, and the sampling cups are arranged in a rotary array and are connected with the moving mechanism through a support frame. The water pump is communicated and fixed with a water injection pipe through a sampling pipe, a rotary joint is mounted atthe joint of the water injection pipe and the sampling pipe, and the rotary joint is assembled on the placing disc. The end of the motor base is fixed to the placing disc, a driving mechanism is installed in the middle of the top end of the motor base, and the movable end of the driving mechanism is connected with the water injection end of the water injection pipe. The automatic sampling device for sewage detection is good in stability and high in sampling efficiency, and is time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of sewage detection, in particular to an automatic sampling device for sewage detection. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse.
