Example Embodiment

[0028] Example one:

[0029] In this embodiment, see Figure 1~4 , A seawater sample automatic distribution and backwashing device, which mainly includes three parts: seawater automatic distribution system, pipeline emptying system and pipeline backwashing system, which are respectively controlled by the main control system, as follows:

[0030] The automatic seawater distribution system mainly includes a water collection device 8, a diaphragm pump 10, a multi-parameter detector 4, a TP-TN-COD analyzer 5, a nutrient salt analyzer 24, a grading filter device with a porosity range of 0.45 to 100μ, and waste The liquid pool 1 and a series of solenoid valves. The water outlet of the water sampling device 8 is connected with the suction port of the diaphragm pump 10. The diaphragm pump 10 can absorb and transport seawater samples through the water sampling device 8. The water sampling device 8 includes a hoist Taiwan, one water pump, several large diameter water pipes, the diaphragm pu...

Example Embodiment

[0047] Embodiment two:

[0048] This embodiment is basically the same as the first embodiment, and the special features are:

[0049] In this embodiment, as Figure 5 As shown, in the seawater automatic distribution system, there is also an auxiliary diaphragm pump 9 signally connected to the main control system. The auxiliary diaphragm pump 9 is used as the second water pump, and its pipeline connection method is exactly the same as that of the diaphragm pump 10. , The water outlet of the water collection device 8 is connected with the suction port of the auxiliary diaphragm pump 9. The auxiliary diaphragm pump 9 can also suck and transport seawater samples through the water collection device 8, respectively, to the COD measurement pipeline and the water sample The parameter detection pipeline and the water sample nutrient salt detection pipeline supply water samples. Two water pumps are installed in the water distribution pipeline in this implementation. When the water supply of...

Example Embodiment

[0050] Embodiment three:

[0051] This embodiment is basically the same as the previous embodiment, and the special features are:

[0052] In this embodiment, as Image 6 As shown, in the seawater automatic distribution system, only the diaphragm pump 10 and one water pump are provided. Due to the simple structure, the overall device is more compact and lighter in weight. It is particularly suitable for carrying multiple devices of this embodiment for replacement and simultaneous multiple use. Point detection is used.

Abstract

The invention discloses a seawater sample automatic distribution and backwashing device mainly including three parts of a seawater automatic distribution system, a pipeline emptying system and a pipeline backwashing system which are respectively controlled by a main control system; the seawater automatic distribution system includes a water collecting device, a diaphragm pump, a multi-parameter detector, a TP-TN-COD tester, a nutrition salt analyzer, a classifying filtration device, a waste liquid pool, a safe valve, an ozone generator and a series of solenoid valves. The device can perform water sample on-line analysis on water samples distributed to the detection instruments, and through a main controller, analyzed data are sent back to a ground control console, the automatic distribution of the seawater samples can be realized, and water distribution pipelines and the detection instruments after the completion of distribution are backwashed. The device has the advantages of simple structure, simple operation, and accurate and reliable test analyzed results, can reduce operational risks of seaborne water quality sampling staff, reduces the work intensity, and has important application value for gradually increasing the automation level of monitoring of sea areas surrounding islands.

Description

technical field [0001] The invention relates to a surface water quality detection device, in particular to a marine water sample automatic detection device, which is applied in the technical field of marine environment monitoring equipment. Background technique [0002] Marine environment monitoring is an important part of the development of marine strategy. The country's current marine monitoring tasks are carried out by my country's marine management agencies, aiming at monitoring and maintaining the safety of my country's marine environment. Due to the harsh conditions of working at sea, large ships are currently equipped with professional monitoring equipment to go to sea to perform operational tasks. The cost of a single trip is high, and the corresponding supporting resources and facilities required are as high as hundreds of thousands. Even so, the detection task still requires a large number of professionals to classify and process the collected water samples. Due t...
