Description
Technical field
The present invention relates to marine environmental protection field, and specifically one kind surface water suitable for carrying out micro- plastics sampling
Netting gear and matched sample bottle.
Background technology
Plastic garbage is mostly stable long chain macromolecule polymer, not degradable in natural environment, but can illumination,
Small plastic grain is broken under the effects such as tide, the temperature difference or wind erosion, turns into micro- plastic garbage.Micro- plastics refer to that size is small
In 5 mm plastic optical fibre, particle or film.Micro- plastics have fast enormous amount, speedup, enrichment and release in water body environment
Poisonous and harmful substance, the features such as being detrimental to health with food chain, cause extensive concern.Water body micro- plastics research in China's is still located
In the starting exploratory stage, only fragmentary investigation and sampling is carried out in some waters.The micro- plastics large area of surface water is continuous at present
Sampling is most to borrow plankton net, and plankton net is designed as heavy network of rivers tool, and its network interface is circle, and diameter is small, inflow
Also small, the research vessel speed of a ship or plane is slightly higher to be torn to pieces；And the water layer whard to control when carrying out the micro- plastics of surface water and sampling, and
Network interface inflow deviation is big, it is difficult to ensures the accuracy of sampling.Lack one kind now and be applied to the micro- plastics large area of surface water
The continuous special netting gear accurately sampled.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, discloses and a kind of micro- plastics sampling is carried out in surface water
Netting gear and matched sample bottle,
Netting gear includes：Etting, the etting enclose the filter cylinder for being set as water filtering but retaining micro- plastics, the front end of the filter cylinder be into
The mouth of a river, on the water inlet is largely immersed in below the water surface, small part is bubbled through the water column.
Matched sample bottle water filtering but micro- plastics can be retained, be flexibly connected with the filter cylinder, the filter cylinder retention
Micro- plastics can with current enter the sample bottle in.
Further, this netting gear that micro- plastics sampling is carried out in surface water includes：
One netting gear framework, the framework include section and are bent into rectangular outer frame for circular wire, and section is circular gold
The crossbeam that is cut into of category silk, the sliding sleeve being set on described two vertical edges of rectangular outer frame, set on the sliding sleeve and be axially perpendicular to it
The screw of slide opening axial direction, is equipped with jackscrew in screw, the inner of the jackscrew is against on the vertical edge of the rectangular outer frame；It is described
The both ends of crossbeam are respectively and fixedly connected on two sliding sleeves and parallel with the horizontal edge of the rectangular outer frame；
Multiple buoys, the buoy are located on the crossbeam, between the buoy and the buoy and the rectangular outer frame two
The interstage sleeve for preventing the buoy or so play is also nested with the crossbeam between individual vertical edge；
Multiple counterweights, uniformly fixed multiple connection sheets, the connection sheet are connected by quick draw on the lower section horizontal edge of the rectangular outer frame
Connect multiple balancing weights；
Four hawsers, four hawsers are isometric, and its one end is fixed together, and the other end ties up to the rectangular outer frame respectively
At four angles；
A piece tow strap, one end and one end that four hawsers are fixed together are affixed, and the other end is tied up on sampling ship；
One filter cylinder support, the diameter of the filter cylinder support are less than a quarter of the rectangular outer frame circumscribed circle diameter, and its inwall is set
Put internal thread；
Four double-deck canvas muscle, one end of four double-deck canvas muscle are respectively and fixedly connected at four angles of the rectangular outer frame simultaneously
, the other end relative with four hawsers is uniformly fitted in the outer wall of the filter cylinder support and is fixed in the filter cylinder by rivet and support
Outer wall on；
The etting is four pieces, is shaped as isosceles trapezoid, and its height is waited between the inner outer end with filter cylinder support of rectangular outer frame
Distance, two waists are clipped between the double-deck canvas of described four double-deck canvas muscle and sutured by sewing thread.
Further, extension forms horizontal tail outside horizontal direction on the outer wall of filter cylinder support, extends outside vertical direction
Form vertical fins.
Further, the length of the rectangular outer frame horizontal edge is 100cm, and the height of vertical edge is 70cm.
Further, the etting is that mesh number is 300 mesh sieve thin,tough silk；The rectangular outer frame and the aluminium that crossbeam is a diameter of 1cm
Alloy or stainless steel wire；The hawser and tow strap are metal or linen-cotton rope；The buoy is solid compression foam, PE baton rounds
Body；The balancing weight is plummet.
Further, this sample bottle includes bottleneck, bottleneck, shoulder, body, bottom of bottle, set on the bottleneck with it is described
The external screw thread that the internal thread that filter cylinder support inwall is set is spirally connected；Multiple windows are uniformly opened up on the body, are also opened in the bottom of bottle
If a window, in the sample bottle, corresponding to the position bonding etting of the window.
Further, the sample bottle is metal bottle or plastic bottle, and the etting mesh number is 300 mesh sieve thin,tough silk.
Compared with prior art, the method have the advantages that：
1. the special harvester of the existing micro- plastics of surface water can only carry out small range water body sampling, time-consuming and efficiency is low
Under.Netting gear of the present invention can conveniently and efficiently carry out large area erect-position trawlnet collection sample.
2. often borrow plankton net in the micro- plastics collection of progress surface water at present and carry out, have about for holding network interface
One semi-area, which emerges, needs human intervention incessantly, such as severe sea condition, will be unable to ensure sample quality.Net of the present invention
With from suspension function, network interface is vertical with the water surface, maintains height of water level automatically, it is not necessary to manual control network interface emersion on the water surface
Height, available for the micro- plastics storage of accurate unit of account water body.
It 3. traditional sample collection bottle is integrally fixed on netting gear, can not dismantle, need at sea to carry out after sample collection
Sample and sample transfer operation are rushed, is wasted time and energy, and the micro- plastic grain that may be remained in bottle easily makes the sample collection of next erect-position
Produce error.Influenceed by shifting, operation on the sea is unstable, and the sample bottle that the present invention designs can be pulled down quickly, more renew
Sample bottle carries out the sample collection of next erect-position, rushes sample and sample operation until land laboratory is carried out again, time saving and energy saving, comfortably
Property is good.
