Abstract
The utility model discloses a fresh water zooplankter collecting device and belongs to the field of zooplankter collection. The fresh water zooplankter collecting device comprises a fixing support and a plurality of zooplankter nets arranged at one side of the fixing support and connected with the fixing support, each zooplankter net comprises a conic net body, a net opening ring which expands the front end of the conic net body and is connected with the fixing support and a net bottom tube arranged at the tail end of the conic net body, and a current meter is arranged on the fixing support or in the net opening ring of any zooplankter net. When the fresh water zooplankter collecting device is used, the fixing support is placed in target water for sampling after being connected with a rope and due to the fact that the zooplankter nets and the current meter are arranged on the fixing support, collection of qualitative samples of zooplankter and quantitative samples of large-scale zooplankter can be accomplished through one-time net casting, and therefore sampling operation is simplified and sampling time is saved. Due to the fact that the whole sampling process is conducted on the same target water, sampling errors caused by the fact that because of drifting of ships, multiple sampling positions are not consistent are reduced, and therefore the zooplankter existing amount of the researched position can be analyzed accurately.
Description
Technical field
The utility model gathers field for zooplankton, particularly relates to a kind of freshwater zooplankton sampling instrument.
Background technology
In freshwater zooplankton Sampling Survey process, same sampled point is different according to the requirement of sampling object, conventionally need to carry out the quantitative and qualitative analysis sample that whole zooplanktons are obtained in 4 operations.Under normal circumstances, at each sampled point, needing many people or single gradation to utilize respectively No. 25 plankton nets and No. 13 plankton nets to carry out small-sized and dragging of the qualitative sample of macrozooplankton gets, with hydrophore, adopt and fill 10～50L water sample and carry out the leaching of the quantitative sample of macrozooplankton by No. 25 plankton nets, and adopt dress 1L water sample as the quantitative sample of microzooplankton, thereby complete the collection of whole freshwater zooplankton samples.In whole gatherer process, for the zooplanktons of different sizes, need carry out many people or single gradation adopts different plankton nets to complete, sampling process wastes time and energy, and due to the drift of boats and ships, having there is larger variation in the physical location that should be same sampled point, easily causes sampling error.
Utility model content
For addressing the above problem, the utility model provides a kind of freshwater zooplankton harvester of simplifying sampling operation, saving sampling time, reducing sampling error.
The utility model solves the technical scheme that its technical problem adopts: a kind of freshwater zooplankton harvester, comprise fixed mount, be located at a side of fixed mount and several plankton nets that are connected with fixed mount, each plankton net includes taper dictyosome, struts taper dictyosome front end and the network interface ring being connected with fixed mount and the net bottom pipe that is located at taper dictyosome tail end, on fixed mount or in the network interface ring of any plankton net, is provided with current meter.
Be further used as the improvement of technical solutions of the utility model, fixed mount is a stainless steel coil, and each plankton net is all located in stainless steel coil and is connected with stainless steel coil by network interface ring, and the circle centre position of stainless steel coil is provided with the retainer ring that connects each network interface ring.
Be further used as the improvement of technical solutions of the utility model, the offside at plankton net on fixed mount is provided with hitch frame, and the top of hitch frame is provided with coupling hook.
Be further used as the improvement of technical solutions of the utility model, plankton net arranges 3 altogether.
Be further used as the improvement of technical solutions of the utility model, plankton net comprises 1 No. 13 plankton net and 2 No. 25 plankton nets.
The beneficial effects of the utility model: this freshwater zooplankton harvester in use, by being connected with, putting into target water body after the fixed mount connecting rope of plankton net and sample, because fixed mount is provided with multiple plankton nets and current meter, the operation that makes once to cast net can complete the collection of the qualitative sample of zooplankton and the quantitative sample of macrozooplankton, thereby simplification sampling operation, save the sampling time, because a plurality of plankton nets of whole sampling process are all positioned at same target water body, thereby reduce because boats and ships drift about and cause repeatedly the inconsistent sampling error causing in sample position, can analyse and investigate more exactly the zooplankton standing crop of position.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model the first embodiment overall structure schematic diagram;
Fig. 2 is the utility model the second embodiment overall structure schematic diagram.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model provides a kind of freshwater zooplankton harvester, comprise fixed mount 2, be located at a side of fixed mount 2 and several plankton nets 1 that are connected with fixed mount 2, the net bottom pipe 13 that each plankton net 1 includes taper dictyosome 11, strut taper dictyosome 11 front ends and the network interface ring 12 being connected with fixed mount 2 and be located at taper dictyosome 11 tail ends, is provided with current meter 5 on fixed mount 2 or in the network interface ring 12 of any plankton net 1.
This freshwater zooplankton harvester in use, by being connected with, putting into target water body after fixed mount 2 connecting ropes of plankton net 1 and sample, because fixed mount 2 is provided with a plurality of plankton nets 1 and current meter 5, the operation that makes once to cast net can complete the collection of the qualitative sample of zooplankton and the quantitative sample of macrozooplankton, thereby simplification sampling operation, save the sampling time, because a plurality of plankton nets 1 of whole sampling process are all positioned at same target water body, thereby reduce because boats and ships drift about and cause repeatedly the inconsistent sampling error causing in sample position, can analyse and investigate more exactly the zooplankton standing crop of position.
As the utility model preferred embodiment, fixed mount 2 is a stainless steel coil, and each plankton net 1 is all located in stainless steel coil and is connected with stainless steel coil by network interface ring 12, and the circle centre position of stainless steel coil is provided with the retainer ring 3 that connects each network interface ring 12.
As the utility model preferred embodiment, the offside at plankton net 1 on fixed mount 2 is provided with hitch frame 4, and the top of hitch frame 4 is provided with coupling hook 41.
Arranging of coupling hook 41 facilitates fixed mount 2 and traction being connected with rope.
As the utility model preferred embodiment, plankton net 1 arranges 3 altogether.
As the utility model preferred embodiment, plankton net 1 comprises 1 No. 13 plankton net and 2 No. 25 plankton nets, and current meter 5 is located in any one No. 25 plankton nets.
The concrete use principle of the utility model is as follows: with rope with after coupling hook 41 on hitch frame 4 is connected, put into target water body and tow, No. 13 plankton nets that rely on that mesh aperture strengthens and 1 No. 25 less plankton nets of hole of throwing the net complete the different qualitative sample collection of big or small zooplankton, coordinate the use of current meter 5 simultaneously, the volume of determining the target water body of other No. 25 plankton net of flowing through, completes the quantitative sample collection for macrozooplankton.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
