A water quality detector

Abstract

A water quality detector, belonging to the technical field of water quality detection, which includes a box body, a mounting plate, a telescopic mechanism, a rotating member, a locking mechanism, a detection component, and a liquid inlet component; a pair of mounting plates; two pairs of telescopic mechanisms , wherein one pair is installed on the inner wall of the upper mounting plate, and the other pair is installed on the inner wall of the lower mounting plate; the rotating member is arranged between a pair of telescopic mechanisms on one side, which includes a vertical plate; locking The mechanism is respectively arranged on the telescopic mechanism located on the other side; the detection assembly is arranged on the vertical plate; the liquid inlet assembly is arranged on the rear wall of the box body and connected to the detection assembly through a pipeline. It is convenient for water quality detection, and it is also convenient for the maintenance of the device, and the water body is filtered with a larger particle size during the water quality detection to avoid the impact of larger flakes on the detection operation, and at the same time it is convenient to carry out water samples Quantitative delivery and distribution, and reduce power consumption.

Description

technical field [0001] The invention relates to the technical field related to water quality detection, in particular to a water quality detector. Background technique [0002] Water quality detection has important reference significance and value in water body environment governance, and a reasonable governance plan can be formulated through the detection results of water body environment. [0003] Currently, fast, sensitive and accurate instrumental analysis methods are used in water quality testing, such as dissolved oxygen, biochemical oxygen demand, total oxygen demand, chemical oxygen demand, total organic carbon and other parameters are measured with special analytical instruments. Biological testing includes commonly used bacterial testing and microscope testing, fish toxicity testing to test the toxicity of water, residual toxic substances in the body and ecological testing that reflect the toxicity of water and its impact on the environment.

AI Technical Summary

Problems solved by technology

[0004] Larger detection instruments have the following defects in practical application: First, since each detection sub-instrument is fixed on a fixed plate, and the fixed plate is directly fixed inside the cabinet of the detection instrument, and generally for To facilitate the observation and taking of water quality samples, the sub-instruments used for sub-item detection are often fixed on the outside of the fixed plate, and the liquid pump, control switch, control board and pipelines used to connect the various components are fixed. On the back side of the fixed plate, once the detection instrument breaks down, it is necessary to remove the fixed plate first and then perform inspection and maintenance of the pipeline and related components, so that the existing detection instruments have the disadvantage of being inconvenient for maintenance; second, When testing, it is inconvenient to store and store water samples, which has a great impact on the testing of specific items; third, when testing water quality with high environmental pollution in water bodies, especially in water samples. When pumping, large impurities in the water body (such as aquatic plants, domestic garbage, etc.) will be pumped into the water storage tank, and when the water sample is redistributed, due to the small diameter of the pipe installed in the detector, it is often The phenomenon of pipeline blockage occurs; Fourth, the existing water sample distribution is usually directly extracted through the pump, which will increase the power consumption of the water quality detector, and at the same time, it is more prone to excessive delivery when pumping , so it has a certain impact on water quality testing
