Water sample automatic sampler for monitoring cultivation water quality on-line in sea water factory

Abstract

The invention provides a water sample automatic sampler used for the online water-quality monitoring of seawater factory cultivation, which is characterized in that the water sample automatic sampler comprises a water quality detecting box which is provided with a cover plate; the lower part of the water quality detecting box is provided with a water sample inlet pipe which is connected with a plurality of sampling pipes; the upper part of the water quality detecting box is respectively provided with an overflow pipe and a water sample drainage pipe; the water quality detecting box is internally provided with a plurality of water quality sensors with the upper parts extending out of the box body; the bottom of the water quality detecting box is provided with a drainage pipe; the water sample inlet pipe, the sampling pipe and the drainage pipe are all provided with an electronic valve element. The water sample automatic sampler can realize the detection of multi-point water quality, and has low manufacture cost, good practicability and convenient operation and management.

Description

technical field [0001] The invention relates to an automatic water sample sampling device for on-line monitoring of water quality in industrialized seawater aquaculture, and is especially suitable for sampling and analysis of an on-line detection system for industrialized high-density aquaculture water quality of fish, shrimp and shellfish. Background technique [0002] In recent years, industrialized aquaculture has developed rapidly and is advancing at an unprecedented speed worldwide, and has become one of the important symbols of the modernization process of aquaculture. Since factory farming provides a large number of controllable environmental factors for the production process, it is easier to meet the optimal comprehensive environmental conditions required by the breeding objects, making the farming production process easier to control and adjust, and greatly increasing the reliability and stability of farming production sex. [0003] In the traditional aquaculture ...

Problems solved by technology

At present, in actual work, a large number of water quality monitoring methods are still traditional laboratory manual analysis methods. This method has a long test cycle and cannot monitor water quality parameters in real time, resulting in a lag of several hours or more test data, which affects aquaculture production. High-efficiency and precise operation. In some farms with a high degree of automation, the real-time measurement of water temperature, dissolved oxygen, pH, salinity, ammonia nitrogen and other indicators of the aquaculture water body is carried out by using an automatic real-time monitoring system for main water quality parameters, but usually The operation method adopted is still to collect water samples manually, put the automatic detection instrument into the water sample for measurement, or install the automatic detection equipment into the pipeline or a water treatment unit. A set of automatic water quality detection instruments can only measure a certain For water quality parameters in one place, the number of samples tested is small, it is difficult to represent the overall water quality status of the breeding workshop, and the guiding significance for breeding production is not significant enough
