Summary of the invention
Technical problem to be solved in the utility model provides a kind of planktonic organism sampling netting gear, to solve the defective that sampling device can only be gathered portion in the prior art at every turn.
A kind of planktonic organism sampling netting gear, constitute by two networking tools, every networking tool all comprises etting, network interface circle and net bottom pipe, the upper and lower end of described etting connects network interface circle and net bottom pipe respectively, one end of the network interface circle of described two networking tools is hinged, the locking device that matches is equipped with at the two ends on pin joint opposite respectively, and the bottom of described net bottom pipe is a conical hopper, and funnel exit is equipped with controlled valve.
Described etting is formed by fine canvas and bolting silk braiding, is divided into three sections of upper, middle and lower, and epimere is that fine canvas connects the network interface circle, and the stage casing is a bolting silk, and hypomere is that fine canvas connects the net bottom pipe.
Described bolting silk is numbered JP12, the wide 0.45mm～0.55mm in hole.
Described locking device is a latch structure, a network interface circle load fishplate bar band latch, and another is provided with the pin hole that matches with latch.
Described net bottom pipe is processed by stainless steel, and the net bottom pipe is that cylindrical body adds conical hopper outlet composition, and cylindrical body is the opening shape up and down, is linked together by steel bar, and cylinder lower end and hopper outlet connect, and hopper outlet is the half opening shape.
Be connected with connection cord between described etting and network interface circle and etting and the net bottom pipe.
Described controlled valve is a nut.
Beneficial effect
The utility model can once obtain two duplicate samples in the sampling, can be used for comparing sample effect or backup preservation sample, can improve the science of the young postlarva research of planktonic organism and fish-egg.
