A water quality sampling device and a water quality monitoring system using the device

Abstract

The invention provides a water quality sampling device. The water quality sampling device comprises a sampling closed vessel, a gas input unit and a measuring cell, wherein the sampling closed vessel is provided with a water inlet, a water outlet and a gas inlet, and the water inlet is arranged in a sample cell; the gas input unit is connected with the gas inlet of the sampling closed vessel through a second pipeline; and the measuring cell is connected with the water outlet of the sampling closed vessel through a first pipeline. The water quality sampling device achieves water quality sampling mainly in the way that gas is input into the sampling closed vessel and a water quality sample is pressed out by the pressure of the gas; and the gas input unit does not need to be in direct contact with water in the sample cell, and of course, has low probabilities of blockage and damage, and besides, the pollution degree of the water quality sample in the sample cell is reduced. The invention also provides a water quality monitoring system employing the water quality sampling device.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a water quality sampling device used in a water quality monitoring system. In addition, the present invention also provides a water quality monitoring system comprising the above water quality monitoring device. Background technique [0002] As environmental pollution becomes more and more serious, environmental monitoring technology has become particularly important, and one of the most important tasks is the monitoring of water quality. The water quality monitoring system usually includes a water quality sampling device and a water quality detection device. During the working process, the water quality sampling device is first used to sample the water body, and then the water quality detection device is used to analyze the water body sample to obtain the final result. [0003] The following briefly describes the working process of the water quality sampling de...

Problems solved by technology

[0005] But above-mentioned water quality sampling device also has many defectives and drawbacks in the course of work

[0006] First of all, with the above sampling method, the water pump is in long-term contact with water in the sample pool, which is likely to cause damage to the water pump and shorten the service life of the water pump, and replacing the water pump will waste a lot of manpower and material resources, resulting in the cost of water quality sampling. higher

[0007] Secondly, because most of the actual water samples contain impurities such as solid particles, and the water volume pumped by the pump is relatively large, it is easy to cause blockage inside the pump or its pipeline, affecting the stability of water quality sampling
