Description
Technical field
The invention belongs to water ecology detection fields, are related to a kind of water ecology research detection device, and in particular to a kind of
Fully-automatic siphon enrichment facility.
Background technology
In pond ecosystem, phytoplankton is the first link (also referred to as the 1st trophic level) as the producer, and phytophagous is floating
Animal ingestion phytoplankton is swum, is the second link (also referred to as the 2nd trophic level), the yield (primary productivity) of phytoplankton decides
The yield (secondary productivity) of phytophagous zooplankter, and the latter decides the yield (3 grades of productivity) of small fishes and big
The yield (whole grade productivity) of type fish.In addition to this, one of the important indicator of phytoplankton or body eutrophication monitoring.
It can be seen that the quantitative analysis to planktonic organism is all of great significance in scientific research and production practices.In quantitative analysis
In, the concentration pre-treatment of sample is the key that carry out taxonomic identification, counting.In quantitative analysis, the concentration pre-treatment of sample is
Carry out taxonomic identification, counting key.It is at present water sample 1L to be acquired, through Shandong brother's reagent to the concentration most common method of pre-treatment
After fixation, sample, which shakes up, to be poured into fixed settling vessel on the top of the shelf, fully after precipitation (24-48h), passes through settling vessel bottom
Outlet valve releases bottom precipitation, controls outlet valve, and flow velocity, flow cannot be too big, can not shake settling vessel during being somebody's turn to do, otherwise
Again it to precipitate.Water sample containing sediment is put into the quantitative sample bottle of 100ml, if volume is more than 30ml, also needs to stand
For 24 hours, if volume is less than 30ml, preceding constant volume is counted to 30ml.This method has the following disadvantages：It is inconvenient for operation, it is difficult to control
Flow and flow rate；Equipment volume is big, it is difficult to carry, be unfavorable in the wild handling test sample, handle test sample
Quantity is also very limited.
Patent document CN204128885U discloses a kind of semi-automatic siphon enrichment facility, and needs are down to specified in liquid level
After height (generally at the about 5cm of taper separatory funnel lower end), valve is turned off manually, can not achieve Automatic Control, and
It is complicated using laser ranging probe to level detection.

The plankton net has layer 2-3 screen cloth, and the specification of plankton net is 25#.
Specifically used method is：Acquisition water sample pours into sampling bottle, adds a certain amount of fixer with fixed life of swimming
Object, 48h carry out siphon again later.When starting siphon, it is assembling siphoning installation first, regulates floating ball and plastics infratubal port position
It sets and fixes, plankton net is wrapped at floating ball through-hole lower port, plastic bend tube is inserted through bottle cap or bottle stopper, then cover
Upper bottle cover stoppers bottle stopper, is finally connected to the upper end of plastic bend tube with the fixation of the hose of woven hose, makes the other end of woven hose
Less than the plane where sampling bottle bottom.After assembling, plastic bend tube and woven hose constitute siphon passage, can pinch woven hose
Hose by generate negative pressure by generate siphon or assembling when using others in a manner of generate siphon, after siphon starts, until
Floating ball lower end abuts sampling bottle bottom and stops siphon.
Simultaneously efficiency can greatly improved with four groups of progress in the device, structure very simple, and assembly and disassembly are very square
Just, it is not required to artificially control completely during use, be easy to use quick.
Compared with prior art, beneficial effects of the present invention are with advantage：
1) the set instrument can be carried out at the same time four groups of siphons, and efficiency is greatly improved.Also improve the accurate of experiment simultaneously
Property.
2) apparatus structure is simple, and each parts are very common and cheap, thus cost is very cheap.
3) the device assembly and disassembly are very convenient, and each parts are light, easy to carry, in the wild simultaneously can be to multiple examinations
