Description

Modular nearly bank column deposit collection system

Technical Field

The utility model belongs to the technical field of marine sediment gathers, concretely relates to modular nearly bank column deposit collection system.

Background

At present, a bobbin integral type columnar sediment collector is generally used for sampling offshore columnar sediment, and the working principle of the collector is as follows: the collector comprises an inner bobbin and an outer bobbin, namely, the stainless steel outer bobbin is additionally sleeved with the detachable inner bobbin made of plastic, wherein the outer bobbin is mainly used for bearing the pressing action of external force during sampling, and the inner sleeve is mainly used for retaining sediment samples entering the bobbin during the pressing process. When the sampling is finished, the operation of sectioning and independently packaging the columnar sediment sample on site is often needed.

However, when the collector ascends to the deck of the sampling ship, the collector needs to be horizontally placed during sampling due to the long bobbin, and then the inner bobbin with the columnar sample is slowly and uniformly drawn out from the tail end of the collector. Generally, in order to facilitate the sectional sampling of the inner bobbin, the inner bobbin is generally composed of two parts which are vertically opened and closed in half, after the inner bobbin is drawn out, one side of the inner bobbin is fixed, the other side of the inner bobbin is opened, a measuring scale is placed beside the bobbin, and the sectional sampling is correspondingly performed according to the scale of the measuring scale. If the inner bobbin is not taken out, the bobbin seam joint is easy to deform, so that the seam at the seam joint is too large, and sediment samples leak or leak.

In summary, the sampling process using the bobbin-integrated cylindrical sample collector is very complicated, and has the following main disadvantages:

1. the whole length of the column sample is possibly compressed, and the vertical distribution condition of the in-situ column sample cannot be truly and objectively reflected. After the sampling is finished, the sample needs to be laid horizontally for sampling, and the samples of the columnar samples in each layer are horizontally released from vertical stress, so that the samples can horizontally move left and right, and errors are generated in sectional sampling.

2. Because the inner bobbin is designed to be opened and closed vertically in half, the seam is simply pressed before sampling for opening and closing after sampling, and if the columnar sample is hard, the inner bobbin is likely to be cracked along the seam, so that sampling failure is caused; if the collected columnar samples need to be subjected to gap water analysis, gap water is lost or flows into the next layer of columnar samples due to burst at the joints, and certain experimental errors are caused.

3. For a columnar sample with high viscosity, the sample is likely to be directly taken out when half of the inner tube is opened, and the layering of the original columnar sample is possibly influenced, so that the sampling failure is caused.

4. For the columnar sediment sample with the silt texture, once the columnar sample is laid down, the sample on the outermost layer can leak from the overflow hole of the columnar sampler, and the soft and thin sediment sample is easy to horizontally expand and move after being laid down, so that the graduated and sectional sampling is difficult to perform by using a measuring ruler, and especially when the sectional sampling interval is required (for example, sampling is performed every 1cm or 2 cm).
