detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1, the utility model provides a portable shallow water columnar sediment sampling device, including a main pipe 6 and a plexiglass sampling pipe 10, and the top of the main pipe 6 is fixed with a first hydraulic control check valve 5. The top of the main pipeline 6 is fixed with a second hydraulic control check valve 7, the top of the main pipeline 6 is fixed with a plurality of air holes 4, and the top of the first hydraulic control check valve 5 is fixed with a self-contained handle 3 , and the self-contained handle 3 extends out of the main pipeline 6, the top of the self-contained handle 3 is fixedly provided with a hook and groove connection system 2, and the bottom end of the main pipeline 6 is fixed with a plexiglass sampling tube 10 through a two-way nut 8.

Further, the hook and groove connection system 2 is fixedly connected with an additional handle 1, and the top of the additional handle 1 is fixed with a hook and groove connection system 2, and the additional handle 1 is a stainless steel hollow tube. According to the actual water depth, it is determined whether to add an additional additional handle 1, The sampling work is facilitated, and the additional handle 1 of the stainless steel hollow tube has strong pressure and corrosion resistance, which can effectively prolong the service life of the additional handle 1 .

The self-contained handle 3 and the main pipe 6 are stainless steel hollow pipes. The self-contained handle 3 and the main pipe 6 of the stainless steel hollow pipe have strong pressure and corrosion resistance, which can effectively prolong the service life of the self-contained handle 3 and the main pipe 6 .
