preferably, distance vertically 1/5 of the container height that concentrates described in being not less than between curved protruding peak level point and the valve port of described atmospheric valve upwards on described bend pipe.
preferably, described filter screen adopts nylon wire, and the mesh diameter of described nylon wire is no more than the planktonic transverse diameter of water body to be collected.
further preferably, the mesh size of described filter screen is at 20～600 orders/inch.
still more preferably, the mesh size of described filter screen is 400 orders/inch.
due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the apparatus structure that concentrates of the present invention is simple, easy to operate, and concentration time is short, after finishing, sampling can detect fast the planktonic organism A wide selection of colours and designs of collection to water sample.
Brief description of the drawings
the structural representation that accompanying drawing 1 is the planktonic device that concentrates of water body of the present invention;
wherein: 1, fixed mount; 2, the container that concentrates; 3, water filling port; 4, freeing port; 5, dewatering outlet; 6, bend pipe; 61, water valve; 7, filter screen; 8, supporting network; 9, atmospheric valve; 10, collection bottle.
Embodiment
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in Figure 1, the planktonic device that concentrates of a kind of water body, comprise fixed mount 1 and be fixedly mounted on the container 2 that concentrates with closed inner chamber on fixed mount 1, concentrate and there is the water filling port 3 of the portion of being located thereon on container 2, be positioned at the freeing port 4 of its bottom, be opened in the dewatering outlet 5 of its sidepiece, 5 places, the dewatering outlet upwards curved protruding bend pipe 6 that is permanently connected, bend pipe 6 is provided with water valve 61, concentrate in the inner chamber of container 2 and be also removably provided with for collecting the planktonic filter screen 7 of water body, be supported on the supporting network 8 of filter screen 7 belows, filter screen 7 and supporting network 8 in the inner chamber of container 2 that concentrates between dewatering outlet 5 and freeing port 4, the concentrate below of container 2 is also provided with atmospheric valve 9, the valve port of atmospheric valve 9 is positioned at filter screen 7 tops.
in order to ensure the required abundant planktonic organism of experiment of concentrating, and prevent planktonic fleeing from, on bend pipe 6, upwards between curved protruding peak level point and the valve port of atmospheric valve 9, distance is vertically not less than 1/5 of container 2 height that concentrate, and on bend pipe 6 upwards curved protruding peak level point not higher than water filling port 3.
escape out in order to prevent planktonic organism from seeing through filter screen 7, the mesh diameter of filter screen 7 is no more than the planktonic transverse diameter of water body to be collected, the mesh size of general filter screen 7 is between 20～600 orders/inch, and in the present embodiment, filter screen 7 has been selected the nylon wire that mesh diameter is 400 orders/inch.
use the above-mentioned device that the concentrates planktonic concentration process of water body that concentrates below in conjunction with concrete elaboration of accompanying drawing 1 from a large amount of water body samples:
1) container 2 that will concentrate is fixedly mounted on fixed mount 1, and filter screen 7 and supporting network 8 are installed in the inner chamber of container 2 that concentrates;
2) close the atmospheric valve 9 of the container 2 that concentrates, and open water valve 61, contain planktonic water sample by water filling port 3 to adding in the container 2 that concentrates;
3) continue to add water sample in water filling port 3, after treating all water sample filling, leave standstill while no longer there are flowing out in the mouth of pipe of bend pipe 6, close the water valve 61 on bend pipe 6;
