The invention discloses a
water quality detection device based on
water pressure feedback multi-layer single-point detection. The
water quality detection device comprises a
water pressure feedback self-adaptive depth single sampling mechanism, a rotary single-point detection mechanism, a cross
contamination prevention and
water immersion correction mechanism, a spiral resistance removal fixed control site power mechanism and a main operation self-control
assembly. The invention belongs to the technical field of
water quality detection devices, and particularly relates to a water quality detection device based on
water pressure feedback multi-layer single-point detection. In order to solve the problem that cross
contamination is easily generated among water samples at different depths in the sampling process, the water
pressure feedback self-adaptive depth single sampling mechanism is arranged on the basis of dynamic characteristics and a feedback principle, and water pressure driving force in sinking sampling is applied, so that samples at different depths can be obtained through one-time sinking, and the sampling efficiency is improved. Through the cooperation of the rotary single-point detection mechanism and the cross
contamination prevention immersion sample correction mechanism, single-point detection and placement and storage of samples are realized, and the main operation self-control
assembly improves the practicability and
operability of the water quality detection device.
