Description
Technical Field
The utility model relates to the technical field of investigation and monitoring of water area sediments, in particular to a shallow water columnar sediment sampling device.
Background
Sediment sampling refers to the law of accumulation, distribution, conversion and migration of pollutants discharged into a water body in sediment, and sediment samples needing to be collected require interference reduction on the physical and chemical properties of the sediment and the inhabitants in the sampling process in ecological research such as the investigation of the sediment and the like in submersible environment water areas such as ponds, swamps and the like, so that a shallow water columnar sediment sampling device with simple structure and convenient use is urgently needed.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a shallow water columnar sediment sampling device, which is used for collecting columnar sediment and is not easy to separate from the collecting device.
In order to achieve the purpose, the utility model provides the following technical scheme: the shallow water columnar sediment sampling device comprises a pipe body, wherein an exhaust hole is formed in the upper part of the pipe body; a top cover is arranged at the top end of the pipe body, a fixing column is arranged on the top cover, and a top block is arranged at the top end of the fixing column; a hollow fixing plate is arranged on one side of the pipe body, an elastic steel sheet is arranged in the fixing plate, the top end of the elastic steel sheet is connected with one end of an L-shaped connecting piece on the fixing plate, the other end of the L-shaped connecting piece is provided with a hole, and a fixing column penetrates through the hole of the L-shaped connecting piece; the pipe body is also provided with an arc-shaped cavity, and the fixing plate is communicated with the arc-shaped cavity; the L-shaped connecting piece vertically moves along the fixing column to drive the elastic steel sheet to penetrate into the pipe body.
As a preferred technical scheme of the utility model: the pipe body is internally provided with an inserting groove, the position of the inserting groove corresponds to that of the arc-shaped cavity, and the elastic steel sheet is placed into the inserting groove when moving towards the cylinder body.
As a preferred technical scheme of the utility model: one side of the cylinder body is provided with a transparent plastic plate.
Compared with the prior art, the utility model provides a shallow water columnar sediment sampling device, which has the following beneficial effects: the device has simple and practical structure and is convenient for sampling in shallow water environment. After sediment completion is gathered to the body, through pressing down L type connecting piece, drive elastic steel piece and move down in the cavity, later elastic steel piece can pass through the arc cavity and take place deformation, and final elastic steel piece can pass the body bottom and stretch into in the slot to make the body reach confined effect, but gather the end back body bottom convenient and fast seal, even the body can not deviate from more rare the sample of gathering.
Drawings
FIG. 1 is a schematic overall view of the present invention;
FIG. 2 is a schematic view of the internal structure of the present invention;
FIG. 3 is an enlarged view of a portion of the present invention;
in the figure: 1. a pipe body; 2. a top cover; 3. fixing a column; 4. a top block; 5. fixing a plate; 51. an elastic steel sheet; 52. an arc-shaped cavity; 6. an L-shaped connector; 7. an exhaust hole; 8. and (4) a slot.
Detailed Description
Example 1: the working principle and the using process of the utility model are as follows: before a sample is collected, the L-shaped connecting piece 6 is lifted to enable the elastic steel piece 51 to be located in the cavity, so that the normal collection process of the collection equipment is not affected by the elastic steel piece 51, collection is started later, the bottom of the pipe body 1 is inserted into mud at the bottom of a shallow water area, air existing in the pipe body 1 can be discharged through the exhaust hole 7, the quantity of the collected sample is observed through the transparent plastic plate, when the quantity of the collected sample meets the requirement, the L-shaped connecting piece 6 is pressed downwards, the L-shaped connecting piece 6 drives the elastic steel piece 51 to move downwards in the cavity, then the elastic steel piece 51 can pass through the arc-shaped cavity 52 and deform, finally the elastic steel piece 51 can penetrate through the bottom of the pipe body 1 and stretch into the insertion groove 8, so that the pipe body 1 achieves a sealed effect, the bottom of the pipe body 1 can be conveniently and quickly sealed, even if the collected sample is rare, the pipe body 1 cannot be separated, and finally the L-shaped connecting piece 6 is lifted to enable the elastic steel piece 51 to be located in the cavity, the collected sample can fall off due to gravity, and the collection process is completed.
