Abstract
The utility model discloses a collection net for plankton in shallow water areas. The collection net structurally comprises a collection ring and a net cover fixed on the collection ring, and adopts the improvement that a bell-mouth escape-proof net body with a larger top and a smaller bottom is arranged in the net cover, an upper opening propping ring and a lower opening propping ring are respectively mounted on the upper and the lower openings of the escape-proof net body, and the upper propping ring is connected with the inner wall of the net cover. The collection net can be widely used for collecting the plankton in the shallow water areas, and is particularly suitable to be used for collecting the plankton in the shallow water areas in a field practice carried out by university students majored in biology. The utility model has the advantages that the plankton is effectively prevented from escaping, so as to finally achieve the purpose of capturing the plankton more conveniently under the premise of baits by increasing the diameter of the collection ring and further increasing the collecting area. By using the collection net, the collection efficiency can be remarkably improved.
Description
Technical field
The utility model relates to water system plankton sample collecting device, specifically a kind of shallow-layer waters plankton nets.
Background technology
Current, the used instrument of plankton of gathering the shallow-layer waters generally is easy bucket formula plankton nets, the guard that its structure comprises collection ring and fixes on collection ring, plankton enter through collection ring circle mouth and gather in the net, so the size of collection ring mouth directly influences collecting efficiency.Meanwhile, collection ring circle mouth also is the outlet that the plankton of network access is run away.Therefore, collection ring circle mouth diameter is set to a double-barreled question.And, when the collection ring diameter hour, the collection effect of putting into behind the bait also can't be improved.In addition, existing collection net also exists stormy waves will occur problems such as bigger swing slightly greatly and can't satisfy instructions for use.
Summary of the invention
The purpose of this utility model is exactly a kind of collection capacity height will be provided and have the anti-shallow-layer waters plankton nets of escaping function, to improve collecting efficiency.
The utility model is achieved in that this shallow-layer waters plankton nets, the guard that comprises collection ring and on collection ring, fix, in described cover body, be provided with the anti-dictyosome of escaping of up big and down small horn mouth, the described anti-upper and lower mouth of escaping dictyosome is separately installed with support Kou Quan, supports a mouthful circle down, and the described support mouth circle of going up is connected with described guard inwall.
The utility model adopts this structure, and setting anti-escapes dictyosome to have and go up big, little horn mouth structure down, can prevent effectively that plankton from running away.Further, owing to solved the problem of running away, therefore, the utility model can obviously strengthen the collection ring diameter, gathers area thereby increase, and then reaches and make plankton that easier captive purpose under the situation of bait arranged.Therefore, use the utility model can obviously improve collection efficiency.
Under technique scheme, the utility model can be realized like this:
Described collection ring and described anti-escape dictyosome on be provided with bait box between the support mouthful circle body, described bait box is the box body that has pore.
Described bait box is connected to guard by suspension wire.
Described bait box connects Gu Erquan by support arm and is connected to guard.
The lower bottom part of described guard has end mouth and is provided with and is used to control the locking part that end mouth opens and closes.
Described locking part can be formed by involutory plate body by two, and the two ends of plate body have locking hole, and the middle part of plate body is a concave surface, is placed with projection on the concave surface.
The two ends of described plate body offer the fixing hole that is used for fixing mass.
In described guard, be provided with the first anti-dictyosome and the second anti-dictyosome of escaping escaped.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model can described collection ring 1 and described anti-escape dictyosome on be provided with bait box 3 between the support mouthful circle body, described bait box 3 is for having the box body of pore.Described bait box can be connected to guard by suspension wire, also can connect solid bait circle 2 by support arm 11 and be connected to guard 14.In a kind of connected mode in back, solid bait circle 2 is also played a supporting role to guard 14, thereby assurance guard 14 is in softened state, and then is beneficial to the plankton network access.When using the utility model,, if trapping, bait box can be set and, in bait box, put into different bait and trap according to the difference of traping object if the nature collection just can not hung bait box 2.
The lower bottom part that the utility model is preferably in guard has end mouth 12, so that gather the collection of finishing post-sampling.Mouth of the described end can adopt any method for opening and closing well known in the prior art to open with closed.Also can adopt shown in Figure 1 being used to control the locking part 8 that end mouth 12 opens and closes opens with closed.Described locking part 8 can be formed by involutory plate body by two, and the two ends of plate body have locking hole and are used for the cross-under fastening bolt.The middle part of plate body is a concave surface, is placed with on the concave surface to make end mouth 12 better closed projections (not shown).
Shown in Figure 1, the utility model collection ring is provided with pull rope 10 so that whole collection net can be fixed on the floating thing when using.Simultaneously, the utility model can offer the fixing hole that is used to hang mass 9 at the two ends of the plate body of locking part 8.Mass 9 can be the round capsule that weight such as sandstone is housed, and selects what of weight according to the size of stormy waves, with guarantee to gather net vertically.Certainly, the known way that the utility model also can adopt in the prior art other is fixed in the end mouth of guard 14 with mass 9, with guarantee to gather net vertically.
Of the present utility modelly anti-escape dictyosome 13, solid bait circle 2, locking part 8 and mass 9 etc. are independent structures, and are all for convenience detach, therefore are convenient to carrying under the wild environment.
The utility model can be widely used in the planktonic collection in shallow-layer waters, carries out shallow-layer waters plankton when being particularly useful for the biological professional field trip of university and gathers and use.
