It closes, then holds telescopic rod, collector is put into waters to be collected, by falling on designated depth under traction rope, walk around to slow
Slow dragging collector makees ∞ zigzag motion, continues 10~20min, water and planktonic organism enter in collection container, then from water
Collector is taken out, the water in collection container is fallen by phytoplankton net and zooplankter net filtration, then opens sampling valve, respectively will
Phytoplankton and zooplankter are fitted into sample bottle, remove sample bottle, and sealing is stand-by；Retainer plate can be phytoplankton net and float
The object net that moves about is exported with collection container and connecting tube is fixed, avoids the occurrence of obscission, and sampling valve can be anti-in acquisition
Sealing and planktonic organism carry out in sample bottle, and in sampling, control sample enters the speed speed of sample bottle, and strainer then can be to prevent
The impurity such as the grit in sealing enter in collection container, and telescopic rod is then more convenient to carry out the acquisition of planktonic organism, this collector is logical
Phytoplankton net and zooplankter net while the acquisition for carrying out phytoplankton and zooplankter are crossed, and collecting efficiency is higher, it can be with
The acquisition with planktonic organism is widely applied.
Further, depth inductor is provided on collection container.
Beneficial effect using above-mentioned further scheme is: depth inductor can learn the position of collector in water,
How much the planktonic organism that designated depth can be acquired is estimated that positioning is imitated compared to the length entered in water according to traction rope
Fruit is more accurate, and the data obtained are also relatively reliable.
Further, phytoplankton mesh number is 25 mesh, and zooplankter mesh number is 13 mesh.
Beneficial effect using above-mentioned further scheme is: the phytoplankton net of 25 mesh, and the zooplankter nets of 13 mesh can be with
It is effective to capture phytoplankton and zooplankter, prevent the impurity such as grit from entering in net, and complete from water in collector acquisition
After taking-up, the water in collection container can be filtered out, and prevents phytoplankton and zooplankter from water being followed to run out of, influences acquisition knot
Fruit.
Further, rubber antiskid set is provided on telescopic rod.
Beneficial effect using above-mentioned further scheme is: rubber antiskid set can increase the friction between telescopic rod and hand
Power plays anti-skidding effect, prevents telescopic rod from sliding, and collector is fallen into water.
