Description
Technical field
The present invention relates to ocean and water environment scientific domain, specifically a kind of micro- plastics of surface water sample trawlnet.
Background technique
Currently, the planktonic organism surface water acquisition water depth error of sampling is larger, in trawlnet during sampling
Network interface inflow deviation is larger in the process.The plankton haul of sampling is small in size, and round network interface, diameter is small, and etting is short, disengaging
Water is small, more demanding to the ship speed of a ship or plane.Wave effect is generated vulnerable to stormy waves and hull navigation, network interface inflow is unstable, adopts
Sample 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 the defects in the prior art, the present invention provides the table that a kind of anti-wave effect stability is good, sampling precision is high
Layer water body trawlnet.
In order to solve the above technical problems, the present invention provides a kind of surface water trawlnet, comprising: net head；Wing plate, at least two pieces
The wing plate is separately positioned on the two sides of the net head；Etting, the etting design for both ends open, and described etting one end is opened
Mouth is connect with the net head, is equipped with connector in the opening of the etting other end；Net bottom bottle, the net bottom bottle pass through described
Connector is connect with the etting.
Preferably, the net head includes: backboard；Side plate, two blocks of side plates are separately positioned on the both ends of the backboard, and two
Side plate described in block is trapezoidal；The backboard and two blocks of side plates form trapezoidal shape.
Preferably, reinforcing pipe is equipped on the upper bottom surface of the net head.
Preferably, at least two blocks of wing plates are separately positioned on the two sides of the net head by fixing pipe.
Preferably, the etting includes: etting ontology；First end opening and the second end opening, first end opening and
Second end opening is separately positioned on the both ends of the etting ontology；Wherein the first end opening is connect with the net head,
The net bottom bottle is connect by the connector with second end opening.
Preferably, the etting is designed in gradual change type, and the size of the first end opening is greater than the size of the second end opening.
Preferably, canvas beam netware is respectively equipped in first end opening and the second end opening.
Preferably, the net head and the material of the wing plate are aluminium alloy.
Preferably, beam arm is equipped in the networking clothing outer body.
Preferably, the etting ontology is 300 mesh, and the length of the etting ontology 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 surface layer is greatly improved；
2) make the sample devices network interface water-feeding deep be effectively controlled by suspension wing plate to obtain greatly adding with stability
By force；
3) flowmeter can be installed additional, accurately to control and measure flow of inlet water；
4) etting is lengthened to 1.8 meters~2.0 meters, increases permeation rate, is enhanced ship's speed adaptability；
5) high corrosion resistance and the design of high weldability aluminum alloy materials, it is light-weight, it is all kinds of to adapt to ocean, lake and river etc.
It is used in environment.

Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, several changes and improvements can also be made.These belong to the present invention
Protection scope.
As shown in Figure 1 and Figure 2, a kind of surface water trawlnet of the present invention is exclusively for the micro- plastics sampling Design of water body, including net
Head and reinforcing member (reinforcing pipe 4, fixing pipe 6), stabilizing fin 5, etting and net bottom bottle 3 form.
Net head is made of backboard 1 and its side plate of two sides 2, and water inlet network interface designs 610 millimeters × 160 millimeters of rectangularity,
Net head is linked by beam netware 8 with etting ontology 7, while net head two sides (side plate 2) installs suspension wing plate 5 additional and increase stability and control
Network interface processed, which is suspended in fix, adopts water depth, and etting ontology 7 is using 50 microns of bolting silks and is lengthened to 1.8 meters~2.0 meters, etting ontology
500 millimeters of diameter of 7 ports (first port), outside increase beam arm 9, to adapt to the requirement of the low speed of a ship or plane limitation of ship.It can at network interface
Flowmeter is installed additional with accurate flow control, is further ensured that sampling precision.Wing plate 5, etting ontology 7 are screwed with net head,
Disassembly carries transport convenience.For net bottom sample collection using connector 10 and light coil mouth net bottom bottle 3, sampling is convenient.
