Embodiment 1

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

[0030] The seawater automatic distribution system mainly includes a water harvesting device 8, a diaphragm pump 10, a multi-parameter detector 4, a TP-TN-COD detector 5, a nutrient analyzer 24, a graded filter device with a porosity range of 0.45-100 μ, waste The liquid pool 1 and a series of solenoid valves, the water outlet of the water collection device 8 are connected with the suction port of the diaphragm pump 10, and the sea water sample can be sucked and transported by the water collection device 8 by the diaphragm pump 10, and the water collection device 8 includes a winch platform, one water pump, and several thick-diameter water pipes. The diaphragm pump 10 sucks...

Embodiment 2

[0048] This embodiment is basically the same as Embodiment 1, especially in that:

[0049] In this example, if Figure 5 As shown, in the seawater automatic distribution system, there is also an auxiliary diaphragm pump 9 connected to the main control system signal, 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 sampling device 8 is communicated with the suction port of the auxiliary diaphragm pump 9, and the auxiliary diaphragm pump 9 can also absorb and transport the sea water sample through the water sampling device 8, and send it to the COD measuring pipeline and the water sample respectively. 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 the first water pump is ...

Embodiment 3

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

[0052] In this example, if Figure 6 As shown, in the seawater automatic distribution system, only one water pump is provided with a diaphragm pump 10. Due to the simple structure, the device as a whole is more compact and lighter in weight. 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...
