Description
Technical field
The present invention relates to the sampling instrument field of hydroplankton, more particularly to a kind of integral type planktonic organism to gather
Device.
Background technology
Hydroplankton, which refers to, to be moved in water and lacks the drifting organism of effective locomotivity, is divided into phytoplankton again
And zooplankter.Planktonic organism is the important component of aquatic ecosystem, is one of basic link of food chain in water.Swim
Change of the biology to water environment is very sensitive, can be by observing the survival condition of planktonic organism in water environment using this feature
Reach the purpose of monitoring water environment.
At present, the collection to phytoplankton and zooplankter is respectively completed usually using two independent collection nets, this
The pore size of two kinds of nets is different.During field sampling, sample collector adopts respectively according to the order of zooplankter after first phytoplankton
Sample, or by two sample collectors while the sample of phytoplankton and zooplankter is gathered, which increase the time cost of sampling
And human cost, sampling efficiency be not high.
The content of the invention
In order to solve problems of the prior art, the invention provides a kind of integral type plankton sampler, bag
Include hand-held pole and be fixedly connected on the circle body of hand-held pole one end, it is also fixed on the circle body covered with primary filter on the circle body
It is connected with spaced apart from each other first and gathers net and the second collection net, the first collection net and the second collection net respectively swims dynamic
Thing gathers net and phytoplankton collection net, and the aperture that the zooplankter collection net and phytoplankton collection are netted differs,
The bottom of the first collection net is connected with the first sampling bottle by the first sampling valve, and the bottom of the second collection net passes through the
Two sampling valves are connected with the second sampling bottle, for collecting the sample of required phytoplankton and zooplankter.
Further, the zooplankter collection net selects 13# nets, and the phytoplankton collection net selects 25# nets.
Further, the length of the hand-held pole is adjustable to be fixedly connected on the hand-held pole other end by rotation
Handle the length of the hand-held pole is adjusted.
Further, the primary filter and the first collection net and the second collection Netcom cross fastener be fixedly connected on it is described
On circle body.
Further, the fastener is clip.
Further, the fastener is 4, is arranged at equal intervals on the circle body.
The present invention compared with prior art, can realize the fishing simultaneously to phytoplankton and zooplankter, be adopted without multiple
The operation of sample personnel or progress repeatedly, it is simple to operate, it is time saving and energy saving.
Brief description of the drawings
Fig. 1 is the schematic diagram of the integral type plankton sampler of the present invention；
Fig. 2 is the schematic diagram of the collection net of the integral type plankton sampler in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
With reference to figure 1, Fig. 2, integral type plankton sampler of the invention includes hand-held pole 1 and is fixedly connected on hand-held pole
The circle body 2 of 1 one end, covered with primary filter 3, the impurity larger for screening out deadwood and rotten leaf etc., the circle body 3 on the circle body 2
On be also fixedly connected with it is spaced apart from each other first collection net 4 and second gather net 5, it is described first collection net 4 and second gather net 5
Respectively zooplankter collection net and phytoplankton collection net, the zooplankter collection net and phytoplankton collection net
Aperture differs, and 13# nets can be selected in the zooplankter collection net, and 25# nets can be selected in the phytoplankton collection net, so as to real
Now to being gathered while collection zooplankter and phytoplankton.
With reference to figure 1, the primary filter 3 is fixedly connected with the described first collection net 4 with the second collection net 5 by fastener 10
On the circle body 2, the fastener 10 is preferably clip, and the fastener 10 is preferably 4, is arranged at equal intervals at described
On circle body 2, the fastener 10 can be 6 or more, so as to realize to the primary filter 3 and the first collection He of net 4
Second collection net 5 is firmly fixed.
With reference to figure 1, the length of the hand-held pole 1 is preferably adjustable, and the hand-held pole 1 is fixedly connected on by rotation
The length of the hand-held pole 1 is adjusted the handle 11 of the other end, so as to adapt to different sample requirements.
With reference to figure 2, the bottom of the first collection net 4 is connected with the first sampling bottle 8 by the first sampling valve 6, and described the
The bottom of two collection nets 5 is connected with the second sampling bottle 9 by the second sampling valve 7, for collecting required phytoplankton and swimming
The sample of animal.
During work, the hand-held pole 1 is held, the circle body 2 is immersed in the trapping for carrying out planktonic organism in water body, swims
Biology enters the described first collection net 4 and second by the mesh of the primary filter 3 and gathered in the string bag of net 5；After trapping terminates,
Unnecessary water is filtered off, the sampling valve 7 of the first sampling valve 6 and second is opened, by the zooplankter filtered and phytoplankton sample
It is directed respectively into the sampling bottle 9 of first sampling bottle 8 and second of label, adds fixative and fix, experiment is transported in refrigeration back
Room.
Although be described in detail to the present invention in conjunction with the embodiments, it should be understood by those skilled in the art that
Ground is that the present invention is not limited only to specific embodiment, on the contrary, in the various amendments without departing from the application spirit and essence, is become
Shape and replacement are all fallen among the protection domain of the application.
