Description
Technical field
Water quality monitoring technical field is the utility model is related to, more specifically to a kind of portable anti-adjustable depth of turbulent flow
Siphon sampling apparatus.
Background technology
With developing rapidly for social economy, China's problem of environmental pollution is increasingly highlighted, and particularly water environment pollution is presented
Extension, intensification trend.In order to strengthen water environment treatment monitoring, the distribution situation of pollutant in water body is grasped, detected in time,
Need to carry out the work such as substantial amounts of sampling of water quality, so as to the ageing and accuracy of the water sampling water quality to ensure.
For live water body sampling work, according to《Quality standard for surface water》(GB3838-2002) regulation is " it is required that water sample
Natural subsidence 30min after collection, the non-settlement section in upper strata is taken to be analyzed by prescriptive procedure ".《Surface water and sewage monitoring technology
Specification》(HJ/T 91-2002) regulation " if containing settleable solids in water sample, cartridge type glass is poured into after should institute's water sampling be shaken up
Glass container, 30min is stood, the water sample without settleable solids but containing suspended solid is moved into sample container and adds guarantor
Deposit agent ".《National surface water environment quality monitoring net monitors Mission Operations guiding book》Middle regulation is " if monitoring section water sample is clear
Clear, scene can directly carry out water sample packing without natural subsidence 30min ".And in actual samples, perform above-mentioned specification compared with
It is difficult.Required according to above-mentioned standard, water sample needs to stand 30min in sampler, then needs to be inserted to water sample top layer 50mm with suction pipe
Following position carries out once or repeatedly drawing water sample, and operation is more troublesome, if containing a large amount of suspended materials in water sample, passes through suction
Pipe once or repeatedly draws water sample, easily forms water quality turbulent flow, causes to contain a large amount of solid suspension matter, shadow in institute's water sampling
The detection of Xiangshui County's matter.
In addition, with the renewal and development of technology, water quality acquisition technique with water quality monitoring technology in order to be combined at present,
Automation water-supply method gradually is developed into, wherein the water fetching device automated is varied, it is both simple including intake pipe, water bottle etc.
Water fetching device, include the large-scale water fetching device being connected with water pump again.The fields such as environmental quality monitoring of developing into of technology provide
Very big facility, improve the ageing of detection.However, the problem of water quality turbulent flow is still the puzzlement in industry.
The adverse effect that water quality turbulent flow is brought mainly includes two aspects.First, suspended in institute's water sampling containing a large amount of solids
Material, water quality detection are affected.Secondly, bulky grain solid material buildup also results in the blockage problem of intake.
In order to overcome water quality turbulent flow adverse effect, through retrieval, more skill also has been disclosed in the prior art
Art scheme, such as China Patent No. 200910024538.5, this application case discloses a kind of side for protecting water inlet of water sampler
Method, it is intercepted to a large amount of suspended materials and silt etc. by primary protection screen pack and secondary filtration head, adopted so as to protect
Storage water inlet.The device plays a role preventing the blocking of collector water inlet.But this application case overall structure compared with
For complexity, cost is higher, in order to ensure that the part of screen pack and filtering head can effectively be run, undesirably increases cleaning dress
Put, further increase cost and structural complexity.China Patent No. 201210472785.3, this application case disclose a kind of water
The water quality monitoring system of matter sampler and the application device, it, will by gas by being passed through gas to closed sampling device
Water sample extrudes, and realizes sampling of water quality, Gas Input part with water without directly contact, it is not easy to results in blockage, damages
Phenomenon, and due to without extra draw power, phenomenon is stirred in the absence of when drawing;Although the however, gas components of this application case
It is not easily blocked, but the water inlet pipe mouth of acquisition water sample opens down from sample cell, and the process that water sample automatically flows into still has introducing
The possibility of deposition solid and suspended particulate, long-term use also result in water inlet blocking.And the introducing of gas components adds volume
Outer cost, it is unfavorable for promoting.
It was found from above-mentioned analysis, prior art is to be lacked from the angle of protection water inlet to overcome caused by water quality turbulent flow mostly
Fall into, usual way is to increase filter screen or filter to increase defence line, is not considered from the source that water quality turbulent flow occurs but, therefore
Also simply cure the symptoms, not the disease, do not tackle the problem at its root.
China Patent No. 201420600029.9 discloses a kind of new water quality collector, and this application case will be adopted by the body of rod
Collection bottle is positioned in water, treats that water body is stably acquired, bottle stopper is combined setting by the device with rope and elastomeric element, passes through rope
The collection and closing of water sample are realized in sub- folding and unfolding, and this device is not susceptible to stir in gatherer process, can be avoided during sampling a large amount of solid
The defects of suction of body particle, overcoming traditional collector easily makes water quality produce muddiness, and a large amount of impurity introduce.This application case can
With say had contemplated that never produce water quality turbulent flow angle come prevent water intaking when solid particle introducing, but its still exist with
Lower defect:1) serialization of sampling can not be realized;2) such as rubber band or spring part are set, and long-term shrink is easily damaged.
In order that collection water sample serialization, there is also the water fetching device that some utilize simple principle in the prior art.As in
State's patent No. 00122194.9 discloses a kind of method and apparatus of liquid-lifting siphonage, this application case using atmospheric pressure and
The rule of siphonage, reach liquid and draw the effect put forward, make its process continuous and automatic of fetching water, without the use of electrical equipment.In
State's patent No. 201010501514.7 discloses a kind of vavuum pump auxiliary siphon off water device and method.The device is also based on saving
About the direction of the energy considers, using siphon principle, is started siphon using vavuum pump, siphon off water pipe is kept continuously
Stable operation.Although above two device make use of siphon principle, attempt that using simple mechanism automatic continuous take can be completed
Water process.However, application is narrower, can not solve the defects of water quality turbulent flow occurred during water intaking.
Therefore need a kind of simple and practical water fetching device of research and development badly, the defects of water quality turbulent flow can be overcome, and can realize from
The continuous water intaking process of dynamicization.
