Description
Technical field
The utility model belongs to aquatic attitude monitoring technical field, especially relates to a kind of plankton harvester, is applicable to hydroplankton investigation sampling.
Background technology
Plankton is to suspend to live in the aquatile in the water.They or the ability of not moving about fully, the ability of perhaps moving about very a little less than, can not do moving of long distance, also be not enough to resist the mobilization force of water.Plankton comprises phytoplankton and zooplankton two big classes; Usually the plankton individuality is very little, but quantity is many, and it is wide to distribute; Occupy an important position aquatile circle; Be not only the important feed foundation of fish, its quantity indicates the height of aquatic productivity to a certain extent, and its structure of community and kind are formed and be commonly used to estimate the water ecological setting present situation.Therefore, the plankton investigation is usually as one of of paramount importance project in the aquatic attitude investigation.
Though the plankton build is very little, but the size differences of certain limit is arranged, but different brackets divided by planktonic size, like nanoplankton and net plankton.Net plankton is meant and can fishes for plankton net that China's No. 25 nets commonly used are the criteria for classifying.For a long time, China uses the qualitative collection net of recommending in " lake survey ABC " (1956) always, and this net adopts No. 25 (64um), No. 13 (86um) bolting silks to be made into the conical net of gathering, and the about 20cm of bore is about 64cm; The former is used to gather phytoplankton, and the latter is used to gather zooplankton.Collecting method is that plankton net is tied up on bamboo pole, in water, slowly drags, and filters certain water yield, and after plankton was concentrated, the sample bottle of packing into was accomplished and gathered.
Utilize this netting gear to sample to need the special messenger to take time and gather, can waste time when reality is worked in the open air, impurity, rubbish etc. get into netting gear easily and cause drainage not smooth in addition, reduce collecting efficiency.
The utility model content
The purpose of the utility model is the problems referred to above that exist to existing technology, and a kind of plankton harvester is provided, and this apparatus structure is simple, and is easy to use, can effectively practice thrift manpower and time.
The purpose of the utility model can realize through following technical scheme:
A kind of plankton harvester; Comprise phytoplankton net, zooplankton net, first floating body and second floating body; First floating body is connected through fixture with second floating body; The phytoplankton net is connected with fixture respectively with the zooplankton net, and first floating body and second floating body are provided with stay cord.
Aforesaid fixture comprises first dead lever and second dead lever; The first dead lever two ends are fixedly connected with second floating body with first floating body respectively; The second dead lever two ends are fixedly connected with second floating body with first floating body respectively, and the phytoplankton net is connected with first dead lever with the zooplankton net.
Aforesaid first dead lever and second dead lever are set in parallel between first floating body and second floating body.
Aforesaid phytoplankton net and zooplankton net are respectively arranged with the first network interface circle and the second network interface circle, are articulated and connected between the first network interface circle and the second network interface circle, and first dead lever is connected with the second network interface circle with the first network interface circle respectively through latch.
Aforesaid first floating body and second floating body are the ship type.
The porch of aforesaid phytoplankton net and zooplankton net is provided with taper and draws in the net.
Compared with prior art, the beneficial effect of the utility model is: 1, simple in structure, easy to use; 2, stable and reliable operation, cost is low; 2, can effectively practice thrift manpower.

Embodiment
Explain further details below in conjunction with the technical scheme of accompanying drawing to the utility model.
Embodiment:
As shown in Figure 1; A kind of plankton harvester; Comprise phytoplankton net 3, zooplankton net 4, first floating body 1 and second floating body 2; First floating body 1 is connected through fixture with second floating body 2, and phytoplankton net 3 is netted 4 with zooplankton and is connected with fixture respectively, and first floating body 1 and second floating body 2 are provided with stay cord.Fixture comprises first dead lever 5 and second dead lever 6; First dead lever, 5 two ends are fixedly connected with second floating body 2 with first floating body 1 respectively; Second dead lever, 6 two ends are fixedly connected with second floating body 2 with first floating body 1 respectively, and phytoplankton net 3 and zooplankton are netted 4 and be connected with first dead lever 5.First dead lever 5 and second dead lever 6 are set in parallel between first floating body 1 and second floating body 2.Phytoplankton net 3 is respectively arranged with between the first network interface circle 7 and the second network interface circle, 8, the first network interface circles 7 and the second network interface circle 8 with zooplankton net 4 and is articulated and connected, and first dead lever 5 is connected with the second network interface circle 8 with the first network interface circle 7 respectively through latch.First floating body 1 and second floating body 2 are the ship type.The porch of phytoplankton net 3 and zooplankton net 4 be provided with the first network interface taper draw in the net 9, the
TwoThe taper of network interface circle draws in the net 10.
It is following that the utility model carries out planktonic collecting flowchart: this device is put into water; First floating body 1 and second floating body 2 swim in the water surface through buoyancy; Phytoplankton net 3 not exclusively is immersed into below the water surface with zooplankton net 4, and the stay cord that is provided with on first floating body 1 and second floating body 2 is fixed on bank trunk or the stone.Current were netted 4 o'clock with zooplankton through phytoplankton net 3; Net rubbish and impurity in the taper block filtered water stream of 4 porch through being arranged on phytoplankton net 3 and zooplankton earlier, plankton is then netted 4 etting along with current get into phytoplankton net 3 with zooplankton, gets into the net head of phytoplankton net 3 and zooplankton net 4 at last; Planktonic abundance in the net head is along with accumulated time; When planktonic amount is enough analyzed, then phytoplankton net 3 and zooplankton net 4 are lifted from the water surface, open the rubber stopper of net head; The plankton sample of gathering in the net head is placed in the 100ml bottle, sends lab analysis back to formalin fixed.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
