It is provided with filter, return pipe, the return pipe, first draining are provided between the self priming pump and the water sample bucket
Be respectively arranged with valve on pipe, second drainpipe and second sampling pipe, the return pipe, first drainpipe,
Second drainpipe and the bottom valve are adapted setting with the sampler respectively.
Further, the return pipe is connected with first sampling pipe by threeway.
Further, the water sample bucket is made of PE material.
Further, the filter is y-type filter.
Further, the valve is ball valve.
Have following the utility model has the advantages that a kind of water sample automatic acquisition device of the invention, the structure pass through setting bottom valve, filter
And water quality detecting device, so that water always in the first sampling pipe, avoids self priming pump from dallying, filter can be preparatory to acquisition water sample
Impurity screening, while by the way that water quality detecting device is arranged in sampling tank, it effectively prevents causing secondary pollution to water sample, so that
Monitoring result is more accurate, and the apparatus structure is simple, substantially increases user experience, is suitble to large-scale promotion.

Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing.
Referring to Fig. 1, the preferred embodiment of the present invention provides a kind of water sample automatic acquisition device, comprising: sampler 1
With water sample bucket 2, water quality detecting device 3 is provided in the water sample bucket 2, the first drainpipe 4, are provided on the water sample bucket 2
Two drainpipes 5, the first sampling pipe 6 and the second sampling pipe 7 are provided with bottom valve 8 and self priming pump 9 on first sampling pipe 6, described
It is provided with filter 10 between bottom valve 8 and the self priming pump 9, is provided with return pipe between the self priming pump 9 and the water sample bucket 2
11, it is respectively arranged on the return pipe 11, first drainpipe 4, second drainpipe 5 and second sampling pipe 7
Valve 12, the return pipe 11, first drainpipe 4, second drainpipe 5 and the bottom valve 8 take with described respectively
Sampling device 1 is adapted setting.Sampler 1 provides water source and supports, can be pond or pipeline, the first sampling pipe 6, which is directly entered, to be taken
Sampling device 1 need to acquire in water sample, and 6 end of the first sampling pipe is equipped with bottom valve 8, it is ensured that in the pipeline of the first sampling pipe 6 always
Water avoids self priming pump 9 from dallying, filter 10 is equipped between self priming pump 9 and bottom valve 8, may filter that bulk particulate matter, protection is certainly
Return pipe 11 is arranged between self priming pump 9 and water sample bucket 2, pacifies on return pipe 11 to control 2 flow of inlet water of water sample bucket for sucking pump 9
Equipped with 12 adjustable backwater flow of valve；Second sampling pipe 7 is artificial sampling line, opens the valve 12 on the second sampling pipe 7
Can direct sample, sampled with detection device in manual sampling Comparability test and guarantee collimation and consistency, it is ensured that Comparability test is true
It is real；First drainpipe 4 is high water level drainpipe, and when water level rises to certain altitude in water sample bucket 2, the water in water sample bucket 2 can
It is overflowed naturally from the first drainpipe 4, equipped with the controllable draining flow velocity of valve 12 on the first drainpipe 4；Second drainpipe 5 is low
Position discharge pipe line, the valve 12 on pipeline be in normally off, the valve 12 can be periodically turned on according to actual conditions, lean on liquid in bucket
Potential difference can water sample in fast evacuation water sample bucket 2, and water sample deposit can be washed away and play the effect for rinsing clean water sample bucket 2；This
Outer water quality detecting device 3, which is directly protruding into PE sample bucket, extracts water sample, can avoid water sample secondary pollution and sundries heap measurement causes
Influence.The structure is by being arranged bottom valve 8, filter 10 and water quality detecting device 3, so that water always in the first sampling pipe 6,
Self priming pump 9 is avoided to dally, filter 10 can be to the acquisition preparatory impurity screening of water sample, while by the way that water quality is arranged in sampling tank 2
Detection device 3 effectively prevents causing secondary pollution to water sample, so that monitoring result is more accurate, and apparatus structure letter
It is single, user experience is substantially increased, large-scale promotion is suitble to.
