Abstract
The utility model discloses a combined plankton collection net which is conical in the whole. The combined plankton collection net comprises a net ring, first net cloth, second net cloth, a first bottom pipe and a second bottom pipe; meshes of the first mesh cloth and meshes of the second net cloth are different; the top of the first net cloth and the top of the second net cloth are both connected to the net ring; the bottoms of the first net cloth and the second net cloth are respectively connected to the first bottom pipe and the second bottom pipe; the first net cloth 2 and the second net cloth are connected by canvas. The combined plankton collection net can be used for collecting various different plankton samples, the condition that as having the net cloth with only one aperture, the traditional plankton net can only collect one large class of plankton is improved, and the work efficiency is improved.
Description
Technical field
The utility model relates to plankton nets, is specifically related to a kind of combined type biological net that gathers that swims.
Background technology
Plankton nets is the instrument that gathers hydroplankton for catching, and can select the suitable etting in aperture according to the size of target organism.General 2 kinds of conventional collection nets: No. 25, aperture is 0.064 millimeter and No. 13, and aperture is 0.112 millimeter.The former is for gathering phytoplankton, protozoa and wheel animalcule etc., and the latter is used for gathering the zooplanktons such as cladocera and copepoda.When needs gather above-mentioned all kinds of plankton, need to adopt two kinds of plankton nets, therefore gather length consuming time, affect operating efficiency.
Utility model content
The technical problem existing for prior art, the utility model provides a kind of combined type biological net that gathers that swims, can collect various dissimilar zooplankton samples simultaneously, improved the etting that traditional plankton net only has a kind of aperture, thereby can only collect the planktonic situation of a large class, improved operating efficiency.
In order to solve existing technical problem, the technical solution adopted in the utility model is:
The combined type biological net that gathers that swims, it is conical that integral body is, and comprises net circle, the first etting, the second etting, the first bottom tube and the second bottom tube; The mesh number of described the first etting and the second etting is different; Described the first etting and the second etting top are all connected in described net circle; The bottom of described the first etting and the second etting is connected to described the first bottom tube and the second bottom tube; Between described the first etting 2 and the second etting, by canvas, connect.
Further, described net circle is stainless, is two semicircles.
Further, described the first etting is nylon, and length is 60cm, and mesh number is 200 order nylon, and screen distance is 0.064mm; Described the second etting is nylon, and length is 60cm, and mesh number is 125 order nylon, and screen distance is 0.112mm.
Further, on described the first bottom tube and the second bottom tube, be equipped with valve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is due to the etting of two kinds of mesh numbers being set on net circle simultaneously, and be all provided with for collecting planktonic bottom tube two kinds of etting bottoms, therefore use the utility model can collect various dissimilar zooplankton samples simultaneously, improved the etting that traditional plankton net only has a kind of aperture, thereby can only collect the planktonic situation of a large class, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model combined type biological structural representation that gathers net that swims.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of combined type biological net that gathers that swims, it is conical that integral body is, and comprises net circle the 1, first etting 2, the second etting 3, the first bottom tube 4 and the second bottom tube 5; Described the first etting 2 is different with the mesh number of the second etting 3; Described the first etting 2 and the second etting 3 tops are all connected in described net circle 1; The bottom of described the first etting 2 and the second etting 3 is connected to described the first bottom tube 4 and the second bottom tube 5; Between described the first etting 2 and the second etting 3, by canvas 6, connect.
Preferably, described net circle 1 is stainless.
Preferably, described the first etting 2 is nylon, and length is 60cm, and mesh number is 200 order nylon, and screen distance is 0.064mm; Described the second etting 3 is nylon, and length is 60cm, and mesh number is 125 order nylon, and screen distance is 0.112mm.
Preferably, on described the first bottom tube 4 and the second bottom tube 5, be equipped with valve 7.
The utility model combined type biological net that gathers that swims is grouped together the collection net of No. 25 and No. 13 two kinds of specifications, net circle 1 is divided into two semicircles, connect down respectively No. 25 and No. 13 ettings, the centre of two kinds of ettings is coupled together by canvas, it is conical altogether that whole combined type gathers net, the bottom of two kinds of ettings is respectively furnished with a bottom collecting pipe, like this, once descend water just can collect phytoplankton, protozoa, wheel animalcule simultaneously, and the zooplankton such as cladocera and copepoda, improved collecting efficiency.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, the in the situation that General Principle as defined herein can be within not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be limited to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
