Description
Technical field
The utility model relates to water body bed mud harvester, particularly relates to and contains benthic water body bed mud harvester under a kind of torrent environment.
Background technology
Zoobenthos is meant the fauna of perching at the bottom, generally comprises aquatic annelid, aquatic mollusk, crustacean and aquatic insect.The purpose of zoobenthos investigation is to understand the kind of zoobenthos in the water body and forms; Distribute and average density and the biomass of zoobenthos on the water body unit area are made reliable estimation; Thereby for the index of putting in a suitable place to breed of demersal fishes in the water body provides certain foundation, also available these enquiry datas are commented the pollution level of water body.
The harvester of using in the prior art is generally boxlike bottom sampler and freshwater mussel bucket type bottom sampler (promptly improve Peter and give birth to bottom sampler).Its principle is a weight of utilizing sampling instrument itself to have, sinks under water, and takes out the bed mud of certain area, thereby calculates the quantity of a certain water body mesobenthos.
Wherein the boxlike bottom sampler be suitable for 7 meters of the depth of waters with interior reservoir or lake in operation.Perpendicular cuts bed mud during operation, gathering area is 192 square centimeters, the degree of depth can reach 10~15 meters.During collection, open valve, connect bamboo pole (or iron pipe etc., drawing high of Locking type valve attaches on it); Put into the bottom then, firmly down push during the contact bed mud, make bottom sampler incision bed mud; Lift the rope of Locking type valve immediately, make its valve-off, then bottom sampler is left the water; Open valve, bed mud just falls in certain container, promptly adopt sample.During little water body sampling, the people stands on Chi Geng and can operate in the pond etc.
And freshwater mussel bucket type bottom sampler style is multiple, carries more convenient.The collection area is 1/16m
2Or 1/20m
2Be made up of two parts, one of which is a pair of freshwater mussel bucket type iron spoon, and top is heavier, is hung on the hook alive with rope; Then collector is sunk under water rapidly, after iron spoon and water-bed the contact, loosen stay cord, the work hook is that shape comes off; When upwards lifting liter, rope is about to the tension of iron spoon, and the iron spoon presss from both sides naturally, and bed mud appearance is clipped in wherein; Unnecessary water flows out in the square hole of per half iron spoon, improves behind the water surface in the impouring box mud appearance of promptly adopting.Larva and oligochaetes and small-sized mollusc are used for entomologizing.
But when in the face of the torrent environment, present domestic scientific research personnel is normally used to be the method that on the iron spoon of freshwater mussel bucket type bottom sampler, adds loads.Make it be sunken to the bottom as far as possible.But the method is also inapplicable in the valley environment that the big perhaps substrate of current is a shale through behind the practice test, is difficult to effectively extract contain benthic bed mud.And the freshwater mussel bucket type bottom sampler price that increases the weight of is higher, and weight of equipment is big, and operation easier is big, is unfavorable for promoting the use of.

In order to address the above problem, overcome in the prior art the existing defective of the collector of zoobenthos under the torrent environment, the utility model provides the collector of zoobenthos under the torrent environment after a kind of the improvement to address the aforementioned drawbacks and problem.
To achieve these goals, the technical scheme of the utility model is following:
A kind of torrent environment Bentonic organism collector comprises grab bucket and grabs bar that the lower end of grabbing bar connects grab bucket, it is characterized in that said grab bucket comprises the frid that can carry sample contents, and said frid comprises is convenient to the passage that current pass, said frid with grab bar and be connected.
Above-mentioned a kind of torrent environment Bentonic organism collector is characterized in that said frid is the circular arc frid.
Above-mentioned a kind of torrent environment Bentonic organism collector is characterized in that, said frid top is provided with web joint, and said grab bucket is connected on the web joint.
Above-mentioned a kind of torrent environment Bentonic organism collector is characterized in that said web joint is provided with steel bar, and steel bar comprises two, and said two steel bar right-angled intersections are provided with.
Above-mentioned a kind of torrent environment Bentonic organism collector is characterized in that, said lower end of grabbing bar connects the point of crossing of two steel bars of grab bucket upper surface.
Above-mentioned a kind of torrent environment Bentonic organism collector is characterized in that said upper end of grabbing bar is provided with abutment ring.
In an embodiment of the utility model, can better carry sample contents in order to make grab bucket, be provided with baffle plate in the side of frid of grab bucket, on the said baffle plate leaking hole is arranged.
The beneficial effect of the utility model is: through the structure of grab bucket is carried out modification, make this product be applicable under the torrent environment scientific research mission to the bottom-dwelling qualitative collection more, and this product is simple in structure, convenient and practical, is easy to promote the use of.
