Description
Technical field
The present invention relates to marine environmental protection field, is specifically a kind of net that micro- plastics sampling is carried out in surface water
Tool.
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, becomes micro- plastic garbage.Micro- plastics refer to that size is small
In the plastic optical fibre, particle or film of 5 mm.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, 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 carrying out being difficult to control water layer when the micro- plastics of surface water sample, and
Network interface inflow deviation is big, it is difficult to ensures the accuracy of sampling.Lack one kind now and be suitable for 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, disclose and a kind of micro- plastics sampling is carried out in surface water
Netting gear, including：Etting, the etting enclose the filter cylinder for being set as water filtering but retaining micro- plastics, and the front end of the filter cylinder is water inlet
Mouthful, on the water inlet is largely immersed in below the water surface, small part is bubbled through the water column.Further include：
One netting gear frame, the frame include section and are bent into rectangular outer frame for circular wire, and section is circle
The crossbeam that is cut into of wire, the sliding sleeve being set on described two vertical edges of rectangular outer frame, is set on the sliding sleeve axially vertical
In being equipped with jackscrew in the screw hole of its slide opening axial direction, screw hole, the inner of the jackscrew is against on the vertical edge of the rectangular outer frame；
The both ends of the 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 threaded through on the crossbeam, between the buoy and outside the buoy and the rectangle
The interstage sleeve for preventing the buoy or so play is also nested with the crossbeam between two vertical edges of frame；
Multiple clump weights, uniformly fixed multiple connection sheets, the connection sheet pass through on the lower section horizontal edge of the rectangular outer frame
Quick draw connects multiple clump weights；
Four hawsers, four hawsers are isometric, its one end is fixed together, and the other end ties up to outside the rectangle respectively
At four angles of frame；
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；
The support of one filter cylinder, the diameter of the filter cylinder support are less than a quarter of the rectangular outer frame circumscribed circle diameter, in it
Wall sets internal thread；
Four double-deck canvas muscle, one end of described four double-deck canvas muscle are respectively and fixedly connected to four angles of the rectangular outer frame
Place and, the other end opposite with four hawsers are uniformly fitted in the outer wall of the filter cylinder support and are fixed in the filter by rivet
On the outer wall of cylinder support；
The etting is four pieces, and shape is isosceles trapezoid, its height wait in the inner support outer end with the filter cylinder of rectangular outer frame it
Between distance, two waists are clipped between the double-deck canvas of described four double-deck canvas muscle and are sutured by sewing thread.
Further, further include sample bottle, the sample bottle water filtering but micro- plastics can be retained, with filter cylinder activity even
Connect, micro- plastics of the filter cylinder retention can enter in the sample bottle with current.
Further, this netting gear that micro- plastics sampling is carried out in surface water includes：
Further, horizontal tail is extended to form outside horizontal direction on the outer wall of filter cylinder support, is extended 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 clump 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 inner wall 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
Lowly.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
Have the function of that network interface is vertical with the water surface from suspension, maintain height of water level automatically, it is not necessary to people's network interface emersion on the water surface in order to control
Height, available for the micro- plastics storage of accurate unit of account water body.
3. traditional sample collection bottle is integrally fixed on netting gear, it can not dismantle, need at sea to carry out after sample collection
Sample and sample transfer operation are rushed, it is time-consuming and laborious, and possible remaining micro- plastic grain easily makes the sample collection of next erect-position in bottle
Produce error.Influenced 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 carries out again, time saving and energy saving, comfortably
Property is good.
