Abstract
The utility model relates to a quantitative collection fishing net for floating algae in rivers. The quantitative collection fishing net comprises a net body, wherein a collector is fixed at the rear end of the net body; the front end of the net body is encircled to form a net opening through a net opening bracket; and the outer side of the net opening is provided with a flow meter which is fixed on the net opening bracket. The collector is used for collecting the floating algae captured by the net body, the flow meter is used for measuring the speed of water flow flowing into the net opening, and the collection time is combined, so that the volume of a water body filtered by the net opening is calculated in the time period, quantitative calculation is conveniently performed, and quantitative survey of the floating algae is finished. The quantitative collection fishing net is suitable for collecting and analyzing floating algae in rivers in the field of aquatic sciences.
Description
Technical field
The utility model relates to the aquatic science field, particularly a kind of rivers planktonic algae quantitative collection netting gear.
Background technology
When carrying out rivers ecologic environment investigation and monitoring, need investigate sampling to planktonic algae, understand species composition and the population abundance situation of planktonic algae, at this time just need use planktonic algae and gather netting gear.Planktonic algae generally need be gathered two kinds of samples in the rivers ecosystem, and a kind of is the qualitative sample that reaction species is formed, and another kind is the quantitative sample of reaction population Fengdu.Qualitative constituent stocks is used the plankton net collection usually, and quantitatively sample is gathered with hydrophore usually.Though qualitative sample can be collected more rich algae species, reflect that more truly the algae species in the water body is formed, can't obtain the abundance of different plant species by conversion; Though quantitatively sample can can't reflect more truly that the algae species in the water body is formed situation by the abundance of the reflection algae species of identifying more truly that converts.
Particularly in dystrophic rivers water body, the species number of algae species and abundance are all lower in the unit volume, use common plankton net and hydrophore more to be difficult to satisfy the demand of rivers ecologic environment investigation and monitoring.
The utility model content
In order to overcome above-mentioned technical matters, the purpose of this utility model is to provide a kind of rivers planktonic algae quantitative collection netting gear that is applicable to poor nutrition rivers water body and is beneficial to quantitative test.
The technical scheme that the utility model adopts is:
A kind of rivers planktonic algae quantitative collection netting gear comprises body, and fixedly there is gatherer the rear end of described body, and the front end of described body surrounds network interface by the network interface support, and the outside of described network interface is provided with the velocimeter that is fixed on the network interface support.
As further preferred embodiment, described body is the little taper shape in the big rear end of front end.
As further preferred embodiment, described body comprises that mesh is 200 purpose nylon wires.
As further preferred embodiment, described flow velocity is counted the rotary cup velocimeter.
As further preferred embodiment, described network interface support is formed by the metallic copper bending.
As further preferred embodiment, described network interface is circular.
As further preferred embodiment, on the described network interface support rope is arranged fixedly, described rope is tied up and is established guiding piece, and described guiding piece is positioned at the dead ahead of network interface when working.
The beneficial effects of the utility model are: gatherer is gathered the planktonic algae that body captures, velocimeter is used for measuring the water velocity that flows to network interface, just can calculate the water body volume that filters network interface in this time in conjunction with acquisition time, be convenient to quantitatively calculate, finish the quantitative interview of planktonic algae.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of rivers planktonic algae quantitative collection netting gear comprises body 1, and this body 1 is that the nylon wire of 200 orders (0.064 mm) is made and formed by mesh, forms the little conical funnel shape in the big rear end of front end.During water body process body 1, water passes through from the mesh of body 1, and wherein planktonic algae can be blocked.
Fixedly there is gatherer 2 rear end of body 1, and the planktonic algae that body 1 is tackled is entering in the gatherer 2 along water body and gathered.
The front end of body 1 surrounds circular network interface 4 by network interface support 3, and network interface support 3 mainly is to be formed by the metallic copper bending, guarantees that it has enough structural strengths.The outside of network interface 4 is provided with velocimeter 5, and this velocimeter 5 is fixed on the network interface support 3 by a thin bar or cord.
Above-mentioned velocimeter 5 is the rotary cup velocimeter, is applicable in the not high hydrological environment of flow velocity.
Also be tied with three ropes on network interface support 3, the front end of these three ropes is tied up and is established guiding piece 6, and guiding piece 6 has certain weight, is positioned at the dead ahead of network interface 4 during work.
Present embodiment is achieved in that fixing guiding piece 6 makes itself and the body 1 vertical desired depth that is sink to rivers, and makes network interface 4 towards water (flow) direction; Under the impact of current, body 1 fully opens, and the planktonic algae from the water body that network interface 4 enters is tackled by body 1 and stores along with the body 1 of conical hopper enters in the gatherer 2; Meanwhile the rotary cup flowmeter is sink to the below of network interface 4 and near the flow velocity of the water body network interface 4 is measured, because approximate by the flow velocity of network interface 4 and network interface 4 near zone water bodys, therefore above-mentioned measurement result is equal to the drainage flow velocity of network interface 4 substantially; After the time of setting, korneforos, body 1 Congjiang is taken out, can calculate flow according to the relation of flow velocity, time and network interface 4 sectional areas, the sample that collects according to gatherer 2 can be carried out the planktonic algae investigation quantitatively, qualitatively again.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain.
