Abstract
The utility model discloses an improved plankton gathering net. The improved plankton gathering net comprises a net head and a sleeve rod, wherein the sleeve rod is arranged on the net head and used for being in thread connection with a telescopic holding rod; the sleeve rod is provided with a fixing bayonet used for fixing the net head to a handrail or a ship rail. The improved plankton gathering net facilitates distinguishing of plankton gathering nets with different apertures, and the misusing probability is reduced; meanwhile, time and labor for plankton sampling are saved, and sampling efficiency is improved.
Description
Technical field
The utility model relates to a kind of Improvement type plankton nets.
Background technology
Plankton in aquatic ecosystem not only quantity preponderate, and the general susceptibility of plankton is larger, and it is short to have growth cycle, can directly observe the advantages such as evaluation.Plankton, as the important indicator of biological monitoring, evaluating water quality pollution and trophic level, all extensively adopts also fruitful both at home and abroad.For understanding an index such as specific bodies of water plankton community population quantity, sociales, pollution indicator species, this water area water-quality is made to preliminary assessment, we need to do quantitative and qualitative analysis sampling to this waters plankton.
The general employing of the qualitative sampling of plankton is at present fixed on plankton net on longer pole, at water body, doing ∞ shape gathers, quantitative collection by plankton net filtration, adopts conventional plankton net comparatively time-consuming in sampling process in certain volume water body, and waste of manpower.The plankton net in different ettings aperture gathers planktonic kind difference simultaneously, but conventional plankton net naked eyes indistinguishable etting aperture, and plankton had not arranged resolution sign on the net, in actual samples process, easily misuse, causes and samples unsuccessfully.
Utility model content
The utility model object is that the defect existing for prior art provides a kind of plankton nets that reduces manpower.
The utility model for achieving the above object, adopts following technical scheme: a kind of Improvement type plankton nets, comprises net head and be arranged at the upper loop bar for being threaded with concertina type holding rod of net head; On described loop bar, be provided with for described net head being fixed on to the fixedly bayonet socket of railing or ship side.
Preferably, described net head is provided with for showing the display screen of plankton screen distance.
Preferably, described net head and described concertina type holding rod are made by stainless steel material.
The beneficial effects of the utility model: reduce in plankton sampling process, the flow process that needs binding plankton net reduces manpower in plankton quantitative collection process, saves the time of sampling, improve the efficiency of sampling, be convenient to differentiate the plankton net of different pore size simultaneously.Utilize the retainer ring on flexible holding rod that collection net is fixed on to ship side, can save manpower; The threaded engagement of flexible holding rod and loop bar, for convenience detach; The bayonet socket that net head arranges is convenient to change plankton net; The aperture display screen of net head is convenient to the aperture that people directly read plankton net used, reduces unnecessary trouble; Loop bar and concertina type holding rod are made by stainless steel material, can be for a long time at underwater work.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
Figure 1 shows that a kind of Improvement type plankton nets, comprise net 2 and be arranged at the loop bar 4 for being threaded with concertina type holding rod 5 on net 2; On described loop bar 4, be provided with for described net 2 being fixed on to the fixedly bayonet socket 1 of railing or ship side.Wherein, described net 2 is provided with for showing the display screen 3 of plankton screen distance, and described net 2 and described concertina type holding rod 5 are made by stainless steel material.
Stainless steel circular net 2, net 2 size are in the same size with biological net, are generally 30-40cm; On net 2, weld the stainless steel loop bar 4 of one 50 centimeter length, apart from net 40 centimeters, be provided with the fixedly fixedly bayonet socket 1 of plankton net, be convenient to be fixed on the railing of sampling boat netting 2.One end of loop bar 4 adopts screw thread, is convenient to be connected with concertina type holding rod 5, conveniently freely dismantles.Display screen on net head gathers the pore size of net for showing to swim, and is convenient to differentiate plankton net.Stainless steel concertina type holding rod 5, total length 3.0m, adopts and is threaded between net 2 and concertina type holding rod 5, facilitates and freely dismantles.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. an Improvement type plankton nets, is characterized in that, comprises net head and is arranged at the upper loop bar for being threaded with concertina type holding rod of net head; On described loop bar, be provided with for described net head being fixed on to the fixedly bayonet socket of railing or ship side.
2. a kind of Improvement type plankton nets according to claim 1, is characterized in that, described net head is provided with for showing the display screen of plankton screen distance.
