The application relates to the technical field of drinking
water sample collection, in particular to an automatic drinking
water sample collection device, which comprises a mounting seat, a pump
machine is installed at the upper end of the mounting seat, a connecting
pipe A is connected to the output end of the pump
machine, a connecting
pipe B slides on the outer side of the connecting
pipe A, a sleeve is connected to one end of the connecting pipe B, a filter screen is connected to the end, away from the connecting pipe B, of the sleeve, a guide rail is installed in the sleeve, and a counterweight and a sealing plug vertically slide along the guide rail in the sleeve. The device drives fish groups and
aquatic organisms near the sleeve by forming bubbles and sound in the
water body, prevents fish swimming and body
mucus and excrement and the like from polluting the
water sample, reduces the interference of biological factors on the
water quality detection result, meanwhile, the gas forms a disturbance zone around the sleeve, the
water body near the sleeve affected by biological secretions can be preliminarily discharged or diluted before the formal water sample is taken, and the detection data deviation is reduced.
