Using technical solution of the present invention, a kind of bank base formula online water analysis system front end sampling pre-processing device.Solution Bank base formula water quality monitoring website in the prior art of having determined causes to block instrument and survey because impurity is excessive excessively, filter effect is undesirable It is larger to measure data deviation.The bank base formula online water analysis system front end sampling pre-processing device of the utility model include floating ball, Six anchor line, sampling system, water inlet line, Water immersion detector, bracket interrelated components, can be applied to bank base formula and supervise online Survey the dynamic monitoring of various water quality parameters in water body.

Compared with prior art, the advantages and positive effects of the present invention are:

1, using Water immersion detector, when water level is lower than water-level alarm line, system can issue alarm signal, be automatically stopped and take Sample.

2, with the tide is flowing and ebbing of detection water body, sampling system is in same water level in water body always, monitors water quality parameter Variation, make monitoring data with more comparativity and researching value.

3, instrument pipeline is preferably protected, extends instrument service life, realizes to the online water quality monitoring of bank base formula Duration and accuracy.

Detailed description of the invention

Fig. 1 is a kind of bank base formula online water analysis system front end sampling pre-processing device schematic diagram of the utility model.

In Fig. 1: 1 being floating ball, 2 be anchor line, 3 be sampling system, 4 be water inlet line, 5 Water immersion detectors, 6 brackets.

Specific embodiment

This construction to the utility model is further described below in conjunction with attached drawing.

A kind of bank base formula online water analysis system front end sampling pre-processing device schematic diagram mainly includes top-down Floating ball 1, anchor line 2, sampling system 3.

Floating ball 1 allows entire sampling system 3 and water inlet line 4 to be suspended in water body always.

Anchor line 2 is used to connect floating ball 1 and sampling system 3, and 2 left and right ends of anchor line are in nature straight condition.

The spiral stainless steel iron wire in 3 periphery of sampling system filters biggish aqueous bio impurity etc., and inside is by both ends pvc pipe Forming a water with intermediate stainless steel steel wire can be with the reservoir of inner-outer circulation, and stainless steel cloth is round by diameter 100um The filtration system of gap steel wire grid composition, water sample continually enter this reservoir after penetrating stainless steel cloth.

Water inlet line 4 extracts water sample from sampling system 3, and then water sample enters online water analysis system, helps through water Matter parameter scene water sample extracts work in real time.

5 one end main electrode of Water immersion detector probe is normally opened contact switch, and when having detected water, probe is in normally opened shape State does not do any movement, system worked well；When main electrode is popped one's head in once do not sensed water, at this time water level just below Position where main electrode probe, i.e. water-level alarm line position.5 normally opened contact switch of Water immersion detector triggers rapidly as normally closed touching Point switch, wet plug data line send a signal to online water analysis CS central processing unit immediately, start alarm mechanism, are System is automatically stopped sampling.

The implementation steps of whole device are as follows:

Floating ball 1 is fixed on 2 top of anchor line first, sampling system 3 hangs on 2 bottom of anchor line.Sampling system (3) outer ring is Spiral stainless steel iron wire, is length 50cm, the cylindrical type of radius 6cm, both ends are embedded in sampling system (3) inner ring stainless steel steel Silk screen extexine.Inner ring both ends are closed PVC pipe, and one end is furnished with standard thread mouth, are connected water inlet line (4)；The other end It is completely closed；Centre is stainless steel steel wire, is length 50cm, the cylinder of radius 3cm, both ends are embedded among PVC pipe. Connection water inlet line (4) is connected to online water analysis system.

According to the water body depth to be measured and the buoyancy feature of floating ball 1, the length of anchor line 2 is manually adjusted, considers water body when falling Riverbed is easy to shoal, and anchor line should be short enough, and left and right ends are in nature straight condition, and entire sampling system is suspended in water body to be measured In.

It first accurately measures floating ball 1 and floats on horizontal plane position to 3 bottommost distance A of sampling system.By 6 one end of bracket depth It buries in mud, it is straight upward and firm.6 water of bracket and mud intersection to top length are not less than (A+0.1) rice.Water is installed Detector 5 is soaked, main electrode probe in one end is fixed on bracket 6, and position is apart from water and mud point of interface (A+0.1) rice vertically upward Place, it is contemplated that the factors such as a little measurement error, 0.1 meter is reserved safe distance；The wet plug data line of the other end passes through bracket 6 Cabling is connected to online water analysis CS central control unit.After above-mentioned each component connection, water body to be measured is uniformly covered with entirely Reservoir inside PVC casing bit, 5 one end main electrode of Water immersion detector probe is normally opened contact switch, when having detected water Probe is in normally open, system worked well；It pops one's head in when main electrode and does not once sense water, water level is just below master at this time Position where electrode probe, as water-level alarm line position.5 normally opened contact switch of Water immersion detector triggers rapidly as normally closed touching Point switch, wet plug data line send a signal to online water analysis CS central processing unit immediately, start alarm mechanism, are System is automatically stopped sampling.

Control instruction is issued by monitoring device, commands internal pump valve, when control water inlet line 4 starts sampling, sampling amount How much, then monitoring device extracts real-time detection in real time, completes each in bank base formula water body by chemically and physically waiting comprehensive means The on-line monitoring of class water quality parameter.

In conclusion by means of the above-mentioned technical proposal of the utility model, when water-level alarm line of the water level lower than setting, water Leaching detector 5 sends a signal to online water analysis CS central processing unit, starts alarm mechanism, system, which is automatically stopped, to be taken Sample, preferably protects instrument pipeline, extends instrument service life, realize to the duration of the online water quality monitoring of bank base formula and Accuracy.On the other hand, the floating buoyancy of the utility model is stablized, and sampling system 3 is designed according to the actual conditions of water body to be measured, No matter tide bulge and fall, sampling system 3 is always in the same water level of water body.It is realized using simple mechanism to the accurate of water intaking depth Control, solves water body in monitoring process, the uncertainty of water level brings the differentiation of measurement result, more accurately obtains The real-time change real-time monitoring of the same water level water quality of water body makes water monitoring data with more comparativity and reference value.

It is not limited to the specific embodiments disclosed for the utility model, all within the spirits and principles of the present invention, institute Any modification, equivalent substitution, improvement and etc. of work, should be included within the scope of protection of this utility model.
