Description
Technical field
The present invention relates to water body sampling instrument, in particular to a kind of shallow water surface deposit sampling apparatus.
Background technique
People are when studying shallow water surface deposit changing rule, it is often necessary to carry out sampling analysis to surface deposit.
However often the loose moisture content of quality is high for shallow water surface deposit, when by external disturbance, original morphosis is easy to be broken
It is bad, it is a greater impact so as to cause processes such as its physical structure, the conversion of sediment water interface material transport, bioconversions.Cause
When this carries out surface deposit correlative study, the interference of sampling process bring should be reduced to the greatest extent.
Currently used surface sediment sampler includes grab bucket-type dredger and profile lead, they exist
Shortcoming.Grab bucket-type dredger destroys greatly deposit layer sequence structure, is difficult to keep original form, and it is inclined to sample success rate
It is low.Profile lead can be sampled to some field environments and be kept the structure of sample, still, in laboratory or one
The relatively soft surface deposit of the ratio formed in a little field environments is still difficult to keep the layer structure of sample script.
Therefore, it is necessary to a kind of new surface deposit sampling apparatuses, for being sampled to soft surface deposit, and
The morphosis for keeping its original well.
Summary of the invention
In order to solve the above problem, the present invention provides a kind of shallow water surface deposit sampling apparatuses, including adopt mud bucket, support
Bar and bottom closing mechanism, the mud bucket of adopting is cylindrical shape, and Open Side Down, in the bottom of the support rod and the top for adopting mud bucket
Centre connection, and the longitudinal axis is overlapped with the longitudinal axis for adopting mud bucket, and the bottom closing mechanism includes back cover cloth, the first drawstring, the second drawing
Rope and winder；
The back cover cloth is rectangle, and length and width are all larger than the bottom surface outer diameter for adopting mud bucket, is attached to described adopt on the lateral surface of mud bucket
Right side, and a line be located at it is described adopt mud bucket open edge, first drawstring is Y shape, one with the support rod
Right side connection, in addition both ends are connect with two angles far from the side for adopting mud bucket open edge respectively；
