Description

Degree of depth self-induction sediment automatic sampler
Technical field
The utility model relates to the enviromental monitoring equipment field, and especially degree of depth self-induction sediment automatic sampler, be applicable to the underwater sediment(s) sampling that river wet season and lake, reservoir etc. have apparent depth difference.
Background technology
The benthal deposit sampling thief is widely used in river, lake, ocean, the water ecological settings such as reservoir, the dwell monitoring of microorganism and water environment of the end, it is the important tool of research water pollution trend and ecology influence, when water depth is different, the dwell kind of microorganism of the end distributes, the individual life activity, in sediment, the release conversion process of pollutant all can be affected, but current sediment sampler is not generally considered the impact of sediment upper strata water depth on sediment sample, perhaps simply use rope to be estimated water depth, these will inevitably exert an influence to the sample analysis result.
The utility model content
The purpose of this utility model is to provide degree of depth self-induction sediment automatic sampler in order to overcome above-mentioned technical disadvantages.
The technical scheme that the utility model technical solution problem adopts is: degree of depth self-induction sediment automatic sampler, comprise for responding to the pressure transducer of water depth, the sampling pipe stored for sediment sample, sampling cutter head for sampling, I shape frame for stable equilibrium's sampling pipe, for discharging the buoy piston tube of sediment upper strata water body, the balancing weight of automatically sampling for sediment, for sealing the non-return valve of sampling pipe, it is characterized in that: described pressure transducer is fixed in I shape frame upper end, and be connected with the water depth measuring instrument by signal wire, by the automatic Conversion Calculation water depth of pressure shown in pressure transducer.
Described sampling pipe material is organic glass, and described sampling cutter head is stainless steel, and the sampling pipe top is threaded with the rotary joint of sampling knife tail end.
Described I shape frame is combined as positive six prismatic structures, to increase the stability of sampling thief.
The upper end piston region of described buoy piston tube is fitted coupling mutually with piston chamber's inwall of sampling pipe tail end, and buoy piston tube middle part is provided with a plurality of apopores.
Be provided with the slip rope between counterweight ring on described I shape frame bottom and sampling pipe lower end tube wall, the balancing weight pendant also can slide along the slip rope on the slip rope, and balancing weight is piece of stainless steel.
The inner position near the buoy piston of described sampling pipe is provided with non-return valve.
Know-why of the present utility model is: along with the depth of water increases, act on the also linear increase of pressure on pressure transducer, when described sampling thief arrives water bottom, pressure on pressure transducer presents constant, according to pressure shown in water body density and sensor, and then calculate sedimental sampling depth.When sampling thief arrives the bottom, because sampling thief no longer sinks or sink to sharply slowing down, the indicated constant pressure of pressure transducer or amplification are sharply reduced, the depth of water that in the time of thus, the indicated calculation of pressure of pressure transducer obtains is sampling depth, thereby realizes the mensuration of sampling depth.
The beneficial effect that the utility model has is: the utility model reasonable in design, can accurately control sampling depth while gathering benthal deposit, sampler structure is stable, in the sediment sampling process, the sequence of sample is not damaged, and is applicable to the needs of the aspect researchs such as environment, ecology, easy and simple to handle, reliable and stable, with low cost, there is fabulous application value.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
