Abstract
The invention provides a surface water dragnet. The surface water dragnet comprises a net head, wing plates, a netting and a net bottom bottle, wherein at least two wing plates are respectively arranged on the two sides of the net head; the two ends of the netting are opened; an opening in one end of the netting is connecting with the net head; a connecting piece is arranged at an opening in the other end of the netting; the net bottom bottle is connected with the netting through the connecting piece. Compared with the prior art, the surface water dragnet provided by the invention has the following advantages that (1) water surface micro-plastic sampling water layer precision is greatly improved; (2) due to the fact that the wing plates are suspended, the net opening water-intake depth of sampling equipment is effectively controlled, and the stability is greatly strengthened; (3) a flow meter can be additionally arranged to precisely control and measure water-intake flow; (4) due to the fact that the netting is lengthened to 1.8 to 2m, the permeation rate is increased, and boat speed adaptation is enhanced; (5) an aluminum material with high corrosion resistance and high weldability is adopted, so that the surface water dragnet is light in weight, and can be used in various environments, such as sea, lake and river.
Description
Technical field
The present invention relates to ocean and water environment scientific domain, the micro-plastics sampling trawlnet of specifically a kind of surface water.
Background technology
At present, in the process of sampling, it is relatively big that the plankton surface water of sampling gathers water depth error, and in trawlnet process, network interface inflow deviation is bigger.The plankton haul volume of sampling is little, circular network interface, and diameter is little, and etting is short, and the turnover water yield is little, requires higher to the ship speed of a ship or plane.Being subject to stormy waves and hull navigation produces wave effect, network interface inflow is unstable, and sampling precision is very poor.It is difficult to ensure that trawlnet keeps the following constant depth sampling of the water surface.
Summary of the invention
For defect of the prior art, the surface water trawlnet that the present invention provides a kind of anti-wave effect good stability, sampling precision is high.
For solving above-mentioned technical problem, the present invention provides a kind of surface water trawlnet, including: net head；Wing plate, at least two blocks of described wing plates are separately positioned on the both sides of described net head；Etting, described etting designs for both ends open, and the opening of described etting one end is connected with described net head, and the opening part at the described etting other end is provided with connector；Net bottom bottle, described net bottom bottle is connected with described etting by described connector.
Preferably, described net head includes: backboard；Side plate, two blocks of described side plates are separately positioned on the two ends of described backboard, and two blocks of described side plates are trapezoidal；Described backboard and two blocks of described side plates form trapezoidal shape.
Preferably, the upper bottom surface of described net head is provided with reinforcing pipe.
Preferably, at least two blocks of described wing plates are separately positioned on the both sides of described net head by fixing pipe.
Preferably, described etting includes: etting body；First end opening and the second end opening, described first end opening and described second end opening are separately positioned on the two ends of described etting body；Wherein said first end opening is connected with described net head, and described net bottom bottle is connected with described second end opening by described connector.
Preferably, described etting is gradual change type design, the size being sized larger than the second end opening of the first end opening.
Preferably, it is respectively equipped with canvas bundle netware at described first end opening and described second end opening place.
Preferably, the material of described net head and described wing plate is aluminium alloy.
Preferably, it is provided with bundle arm at described networking clothing outer body.
Preferably, described etting body is 300 orders, and the length of described etting body is 1.8 meters～2.0 meters.
Compared with prior art, surface water trawlnet of the present invention has the advantage that
1) the micro-plastics sampling water layer precision in water body top layer is drastically increased；
2) make this sample devices network interface water-feeding deep be effectively controlled by suspension wing plate and stability is greatly strengthened；
3) effusion meter can be installed additional, in order to accurately to control and to measure flow of inlet water；
4) etting lengthens to 1.8 meters～2.0 meters, increases permeation rate, and ship's speed adaptability is strengthened；
5) high corrosion resistance and the design of high weldability aluminum alloy materials, lightweight, adapts to use in all kinds of environment such as ocean, lake and river.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art and are further appreciated by the present invention, but do not limit the present invention in any form.It should be pointed out that, to those skilled in the art, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into protection scope of the present invention.
As shown in Figure 1 and Figure 2, one surface water trawlnet of the present invention is exclusively for the micro-plastics sampling Design of water body, forms including net head and girth member (reinforcing pipe 4, fixing pipe 6), stabilizing fin 5, etting and net bottom bottle 3.
Net head is made up of the side plate 2 of backboard 1 and both sides thereof, water inlet network interface is designed to rectangle 610 millimeters × 160 millimeters, net head links with etting body 7 by restrainting netware 8, simultaneously net head both sides (side plate 2) installs suspension wing plate 5 additional increases stability and controls network interface and be suspended in the fixing water acquisition degree of depth, etting body 7 adopts 50 microns of bolting silks and is lengthened to 1.8 meters～2.0 meters, etting body 7 port (the first port) diameter 500 millimeters, outside increases bundle arm 9, to adapt to the requirement of the low speed of a ship or plane restriction of ship.Network interface place can install effusion meter additional with accurate flow control, is further ensured that sampling precision.Wing plate 5, etting body 7 are screwed with net head, and transport facility is carried in dismounting.Net bottom sample collection adopts connector 10 and light coil mouth net bottom bottle 3, and sampling is convenient.
Net head, girth member (reinforcing pipe 4, fixing pipe 6) and wing plate 5 all adopt high corrosion resistance and high weldability aluminum alloy materials, lightweight, tensile strength is high and seawater corrosion resistance.The micro-plastics sampling trawlnet of this surface water, has anti-wave effect good stability, sampling precision height, ship strong adaptability, can be widely applied to the sample collecting of ocean, lake and the micro-plastics of river surface water.
