Description
Technical field
The utility model is related to a kind of utensil that collection is separated for aquatic zooplankter, and referring in particular to one kind can be conveniently fast
The device of the prompt zooplankter for isolating different building shape size.
Background technology
Zooplankter is the minitype aquatic animal that class suspension is survived in water body, and they can not only be the filter food such as silver carp, flathead
Property fish provide bait, moreover it is possible to the occurrence and development of planktonic algae and microorganism are restricted, in the trophic level chain of Freshwater ecosystems
In play a very important role.Raw zooplankter is each variant to the adaptability of environment after different types of, its population knot
The change of structure, number change and sociales and pollution indicator species can indirectly reflect the water quality condition and health status of water body.
Therefore, study the community dynamic of zooplankter in water body, to study the structure of aquatic ecosystem, function, biological productivity with
And eutrophication control has very important significance.But, at present either quantitative or qualitative collection planktonic organism is not
Classify at the beginning of it first being carried out one, the sample identification process for causing the later stage is become extremely complex by this, is exactly in addition usual
Plankton net is a single device, needs to be filtered in biological net in water extraction by hydrophore, these factors
Exist and cause collection planktonic organism work to become very loaded down with trivial details, waste time and energy.
In view of two difficult problems that in the past collection planktonic organism is present：Can not directly by collection in first gatherer process
Planktonic organism is classified at the beginning of carrying out one；Second, plankton net is a single device, it is impossible to while carrying out water acquisition, split
Operating process, wastes time and energy, intricate operation.This problem exactly to be solved in the utility model.
Utility model content
The purpose of the present utility model：Aim to provide a kind of utensil that collection is separated for aquatic zooplankter.Can
First detached problem in zooplankter gatherer process is solved, water acquisition can be combined together with separating again, simplify operating procedure, subtracted
Few workload, saves the time, easy to operate.
To achieve these goals, this device is achieved through the following technical solutions：
It is this to separate the utensil of collection for aquatic zooplankter, including handle 10, hydrophore 1, be arranged in hydrophore
The plunger valve 7 in chamber and it is arranged on the Combined filtering net of hydrophore bottom, it is characterised in that：Described Combined filtering net
It is made up of the inner filter screen 2 and outer filter 3 of two inversion centrum shapes for being suspended at hydrophore bottom；Described inner filter screen 2
The lower vertex of a cone be provided with interior filter chamber control valve 5, described 3 play vertex of a cones of outer filter are provided with outer filter chamber and control valve 4；Thus constitute
Most of Copepods in zooplankter and cladocera can be separated filtration inner chamber and can be less by build in zooplankter
Wheel animalcule, protozoan and algae separate filtration exocoel.
The mesh aperture of described inner filter screen 2 is 0.112mm；The mesh aperture of described outer filter 3 is
0.064mm。
The plunger valve 12 that the described inner chamber of hydrophore 1 is arranged is by shaft-like valve rod 7 and the structure of rubber stopper 6 for being arranged on bottom rod end
Into, the described top of shaft-like valve rod 7 is set in the centre bore of a screw valve 9, and by the support of a Triangle-Profile
Frame 8 is fixed with hydrophore 1；The bottom Jing rubber stopper 6 of described shaft-like valve rod 7 and the structure of limbers 11 for being arranged on the bottom of hydrophore 1
Aquaporin is crossed into controllable.
Described hydrophore 1 is internal diameter for the irony cylinder of 20cm, and the length of the hypotenuse of the inner filter screen 2 is 30cm, institute
The length of the hypotenuse for stating outer filter 3 is 50cm.
The inner chamber control valve 5 for being arranged on the bottom of inner filter screen 2 is the assembly of a stainless steel hollow cylinder and hand control valve,
Its volume is 50ml.
According to this utensil that collection is separated for aquatic zooplankter that above technical scheme is proposed, as a result of double
Separating planktonic organism, the planktonic organism in water body has first been carried out the biological net of different pore size layer plankton net synchronous point
From, and the zooplankter sample for needing concentration can be effectively obtained by the container and valve below plankton net；
Secondly it is exactly to be connected with plankton net through improved hydrophore, by moving up and down hydrophore for control block rubber
In water be put in Combined filter screen and filtered.Operating procedure is simplified, the time has been saved, makes whole operation more easy to be easy
OK.
