Automatic water quality sampler

Abstract

The invention provides an automatic water quality sampler which can ensure detection of various water qualities and avoid contamination and interference among collected samples. The automatic water quality sampler comprises a casing and a sampling body fixedly connected with the casing, wherein the casing comprises a peristaltic pump, a water inlet pipe module, a flow sensor and a control unit, which are arranged in the casing; the flow sensor is connected in series with the peristaltic pump; the control unit is electrically connected with the peristaltic pump and the flow sensor; the water inlet pipe module comprises a rotating disc and a plurality of water inlet pipes integrated on the rotating disc; owing to the rotation of the rotating disc, water quality sampling is implemented by different water inlet pipes each time; a water inlet pipeline connected with the water inlet pipes respectively is arranged in the rotating disc; and the control unit comprises a network communication unit. The automatic water quality sampler not only can be used for ensuring that a water sample collected each time is not contaminated by the water sample collected last time, but also can be used for further preventing the possibility of contamination through automatic replacement of the water inlet pipes.

Description

technical field [0001] The invention relates to the technical field of water quality sampling equipment, in particular to a water quality automatic sampler. Background technique [0002] The water quality sampling device is a device for collecting water quality samples, which can be divided into two types: water quality manual sampler and water quality automatic sampler. The material of the water quality artificial sampler must not affect the composition of the water sample, and it is easy to wash, and there must be no residue on the previous sample; the water quality automatic sampler is suitable for the bucket sampler proportional to the flow rate, it is a An intelligent multi-functional suction-type water sample bottle sampling device can realize multiple sampling methods (quantitative sampling, timing quantitative sampling, timing flow ratio sampling, constant flow quantitative sampling and remote control sampling) and multiple sampling methods according to water sample ...
