Description
Technical field
It is specifically a kind of sample multipoint parallel harvester the present invention relates to a kind of sample collecting apparatus, belongs to water
The liquid sampling technical field such as matter.
Background technology
At present, existing aquaculture technology is very high to the degree of dependence of breeding water body water quality.In aquaculture system,
Quality problem is most important, and quality problem mainly includes:Three nitrogen (ammonia nitrogen, nitrite nitrogen, the nitric acid of aquatic biological itself excrement
Salt nitrogen, is commonly called as " three nitrogen ") accumulation, dissolved oxygen concentration is not enough and the aspect such as skewness, wherein the tightest with the harm of three polluted by nitrogen
Weight.
Because water quality condition is influenceed by many factors such as external environment, aquatic biological species, breeding techniques in aquaculture,
The distribution situation of water quality is often to change over time.In addition, cultivation is often in flow regime, and water is larger, water
Matter situation also varies in the spatial distribution of synchronization.A certain single-point in water body is sampled detection and tends not to
To most representational conclusion.Therefore, while being acquired to the water sample of multiple spot and monitoring section of the water quality to aquaculture process
Management tool is learned to be of great significance.The device being acquired to water sample at present is many, but prior art can be realized
Single-point is sampled, and is limited to the limitation of sampling instrument, is difficult to realize multipoint parallel collection.
The content of the invention
In order to solve problems of the prior art, flexible, sampling efficiency is used it is an object of the invention to provide one kind
High, light easy-to-use sample multipoint parallel harvester, realizes the multipoint parallel sampling to liquid such as water bodys.
In order to realize the object of the invention, the invention provides a kind of sample multipoint parallel harvester, the parallel acquisition
Device includes:Sampling support, sampling pipe, sample memory, buffering tracheae, collection and take out (row) air pump at pneumatic buffer.
The collection support is made up of sampling frame, fixator and handle.Wherein sampling frame can according to sampling location and
The layout of sampled point makes, and making material can be all kinds of section bars and supporting connector.If sampling frame is stratiform, on every layer
Multiple fixators can be installed for fixed sample pipe, fixator position is sampled point position, every layer can arrange many
Individual fixator is realizing multilayer, multi-point sampling.Handle can be arranged on the top of sampling frame, conveniently be put into or take out sampling branch
Frame.
The sampling pipe be plastic straw, diameter 4-6mm, the sampling length of tube of all sampled points should be equal, with ensure take
Each sampled point suction is consistent during sample, realizes that each point average rate is sampled.Sampling pipe one end is fixed on the fixator of sampling support, and one
End is connected to sample memory.
The sample memory capacity will meet the requirement of sampling amount, can be test tube, plastic tank or vial etc., its lid
Upper to install two sampling tube connectors of sealing, one is that, into (row) sample connector, one is into (row) air connector.In sample
Memory inside, enters (row) sample connector and connects one section of sample feeding pipe to sample memory bottom, it is therefore an objective to sample is opened by bottom
Begin filling sample memory, and inside sample memory, enter (row) air connector and be not connected to any sampling pipe, it is therefore an objective to from sample
(row) gas is entered on product memory top, it is to avoid sample is sucked out sample memory and pollutes follow-up pipeline.
The buffering tracheae is plastic straw, and diameter 4-6mm, the length of all buffering tracheaes is consistent, the one of buffering tracheae
End connection sample memory, one end connection collection pneumatic buffer.
The collection pneumatic buffer is a complete container or sealing pipeline, is uniformly provided with thereon identical with sampled point number
Hole, installs connector on hole, connector outer end connection buffering tracheae.Collection pneumatic buffer has tube outlet to be taken out for being connected to
(row) air pump.
For aspiration pump or exhaust pump, power and throughput should meet system requirements, take out (row) gas described (row) air pump of taking out
Pump is connected by pipeline with the outlet of collection pneumatic buffer.Take out (row) air pipe and switching realization is combined to sample memory by ball valve
It is inflated or is vented, extrude the sample in sample memory during inflation, realize that wash bottle is operated, is sucked the sample into during exhaust
In sample memory, sampling is realized.
During practical application, one end of each sampling pipe is fixed on each fixator of sampling support, what be would extend out is each
The sampling pipe other end is connected to the entering on (row) sample connector of each sample memory, and one end of each buffering tracheae is connected into various kinds
Entering on (row) air connector for product memory, the other end of each buffering tracheae is connected on each connector of collection pneumatic buffer,
(row) air pipe will be taken out and be adjusted to exhaust, extract sample, reached after needing sample size, (row) air pump will be taken out in closing, stop sampling.Can
Taken out before formal sampling, arrange 2-3 sample, it is therefore an objective to wash bottle carried out to sample memory, makes the testing result of samples taken more
It is credible.
Present invention also offers the leak check method before being sampled using foregoing parallel acquisition device, specially:
The ball valve that (row) air pipe is taken out in regulation is combined as modes of inflation, and all sampling pipes are put into water, opens air pump to sample storage
Be inflated in device, observed per bubble production of the sampling pipe in water all the way successively, if each sampling pipe occur continuously,
Then proof system air-tightness is good for uniform bubble, otherwise needs to check the sealing of correspondence pipeline or re-starts device group
Dress.
The beneficial effects of the present invention are:
The sample multipoint parallel harvester of present invention design, simultaneously can be fixed multiple sampling pipes by sampling support
In required sampled point, and each collection point sample is extracted into different sample memorys respectively, realizes the multipoint parallel of sample
Collecting work, with collecting efficiency higher.Buffering tracheae and buffer make sample memory keep apart with air pump, it is to avoid
Water pump pollution or damage caused by directly extracting water sample, and suction suffered by each sampled point is identical, realizes that each sampled point is uniform
Sampling.(row) air pipe is taken out by what is be made up of four ball valves, has been conveniently realized and inflation and pumping two is realized by an air pump
The pattern of kind, it is very convenient to switch, and harvester is had preferable controllability.
