Abstract

The invention relates to a water body automatic sampling device. The problems that manual sampling is inconvenient and automatic sampling cannot fully reflect the actual situation of a water body andis not accurate enough are effectively solved. According to the technical scheme, the rotation of an impeller is driven by river water; the impeller drives a first reel to receive a rope and drives asecond reel to release the rope, so that the time interval for sample collecting is proportional to the flow rate of the river water; a signal transmitted by a Hall sensor is used to control the startand stop of a motor; when the motor drives a second rotation shaft to rotate, sample collecting is started; the second reel receives the rope, and the first reel releases the rope; the impeller rotates in the opposite direction; the nearby river water is stirred, so that the river water is not stratified; a floating object entangled on the impeller automatically break away from the impeller; eachtime the motor starts and stops, a planetary gear train drives a first sleeve to rotate at a certain angle to collect a bottle of sample.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an automatic water sampling device. Background technique [0002] Rivers will have wet seasons, normal water seasons, and dry seasons. The time intervals for sampling river water in different periods are different. The flow rate of river water in the wet season is faster than that in the normal and dry seasons. Therefore, the sampling time in the wet season The interval should be shortened accordingly, and the flow rate of the river water changes rapidly. Manual sampling often cannot accurately control the sampling interval. Most of the automatic sampling devices take samples at the set time interval; The impeller, the impeller rotates under the impetus of the river water, and the floating objects such as aquatic plants in the river water are easily entangled on the impeller, which affects the rotation of the impeller and makes the impeller unable to accurately reflect the flow ra...
