Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
As shown in fig. 1-5, a columnar stratified sampling device for shallow water layer sediment comprises a limiting sleeve 1 and a sampling tube 3 slidably inserted into the limiting sleeve 1, wherein the sampling tube 3 is inserted from the lower end of the limiting sleeve 1 and the lower end of the sampling tube 3 extends out from the lower end of the limiting sleeve 1, the lower end of the sampling tube 3 is open, when in use, the limiting sleeve 1 is held by hand or the limiting sleeve 1 is fixed at the edge of a ship or other fixing equipment is adopted to fix the limiting sleeve 1, and the sampling tube 3 is driven to move downwards relative to the limiting sleeve 1 so as to be inserted into the sediment of the shallow water layer for sampling.
The upper end of the limiting sleeve 1 is provided with a sleeve 4 provided with internal threads, and the axis of the sleeve 4 is collinear with the axis of the limiting sleeve 1. And, 4 threaded connection has threaded rod 201 in the sleeve pipe, the lower extreme of threaded rod 201 stretches out and rotatably is connected with sampling tube 3's upper end from sleeve pipe 4's lower extreme, can drive sampling tube 3 through rotatory threaded rod 201 and reciprocate relatively 1 spacing sleeve and then can insert sampling tube 3 into the sediment when spacing sleeve 1 is fixed and when driving sampling tube 3 downstream, and the sediment enters into sampling tube 3 and then realizes the sampling of sediment through the lower extreme opening of sampling tube 3.
The top of threaded rod 201 is provided with convenient operation's carousel 2, and the operator passes through the hand promptly accessible carousel 2 realizes the rotation operation to threaded rod 201. Of course, other means known in the art may be used to drive the threaded rod 201.
In order to avoid that the sample flows out from the lower end opening of the sampling tube 3 in the process of lifting the sampling tube 3 upwards after collection is completed, a hollow end cover 301 is connected to the lower end of the sampling tube 3 in a threaded manner, a plurality of fan blades 13 are arranged in the hollow part of the end cover 301, the fan blades 13 are arranged at equal angles relative to the central line of the end cover 301, one end of each fan blade 13, which is far away from the central line of the end cover 301, is hinged on the end cover 301, when the fan blades 13 rotate to the state that the surfaces of the fan blades are perpendicular to the central line of the end cover 301 (the position of the fan blades 13 at the moment can be called as a first position), the side walls of each fan blade 13 are mutually contacted and form a circle to block the hollow part of the end cover 301, a circle of limiting ring 14 is arranged in the hollow part of the end cover 301 and below the fan blades 13, and when the fan blades 13 are in the first position, the lower, this ensures that the fan 13 cannot be rotated further downwards when it is in the first position. When sediment enters the sampling tube 3 from the end cap 301, the sediment drives the fan blades 13 to open at a certain angle (the position of the fan blades 13 at this time can be referred to as a second position) when the sampling tube 3 is driven downward, and an opening is formed between the fan blades 13, and the sediment enters the sampling tube from the opening. When the sampling tube 3 is moved upwards after collection is completed, there is a tendency for the sediment to move downwards, which drives the fan 13 towards the first position and after reaching the first position the fan 13 is no longer moved downwards and blocks the hollow part of the end cap 301, and the sediment cannot flow out of the end cap 301. When the sediment needs to be taken out of the sampling pipe 3, the end cover 301 is unscrewed.

Similarly, a second through hole 101 is formed in the top of the limiting sleeve 1, and the second through hole 101 communicates the inside of the limiting sleeve 1 with the outside.
The lower end of the threaded rod 201 is connected with the top of the sampling tube 3 through a bearing 8. In order to prevent the sampling tube 3 from rotating relative to the limiting sleeve 1, a plurality of grooves 111 extending along the axis of the sampling tube 3 are arranged on the outer wall side of the sampling tube 3, a plurality of protrusions 112 matched with the grooves 111 are arranged on the inner side wall of the limiting sleeve 1, the sampling tube 3 and the limiting sleeve 1 can be prevented from rotating through the matching of the grooves 111 and the protrusions 112, and the stability of the sampling tube 3 when moving relative to the limiting sleeve 1 can be ensured. Through limiting sampling pipe 3 rotatory to spacing sleeve 1 relatively, at the in-process of gathering the bed mud, if need sampling pipe 3 rotatory, because sampling pipe 3 inserts subaqueous, inconvenient direct carry out the rotation operation to sampling pipe 3, can realize sampling pipe 3's rotation through controlling spacing sleeve 1 rotation.
Further, be provided with a circle of tooth at the lower extreme of end cover 301, through the tooth, when meetting comparatively hard bed mud, can rotate limiting sleeve 1 and drive end cover 301, help inserting in comparatively hard bed mud.
Example two
As shown in fig. 6 to 8, this embodiment is different from the first embodiment in that a mud scraper 5 is added. The mud scraper 5 is disc-shaped, and the diameter of the mud scraper is equal to or slightly smaller than the inner diameter of the sampling pipe 3. Be provided with a plurality of link blocks 6 at the edge of scraper 5, a plurality of link blocks 6 set up for scraper 5's central line equiangularly, and a plurality of link blocks 6 are fixed on the inner wall of limiting sleeve 1's lower extreme, are provided with a plurality ofly on the lateral wall of sampling tube 3 with link block 6 complex spout 601, link block 6 passes spout 601 and fixing with limiting sleeve 1's inner wall, and link block 6 can slide in spout 601, and when threaded rod 201 drove sampling tube 3 and withdrawed into limiting sleeve 1 like this, scraper 5 can be ejecting from the open end of sampling tube 3 with the bed mud in the sampling tube 3, and then the taking out of bed mud of being convenient for.
Specifically, a threaded hole 901 is formed in one end, far away from the mud scraper 5, of the connecting slide block 6, a screw 9 matched with the threaded hole 901 is arranged on the side wall of the limiting sleeve 1, and the mud scraper 5 can be fixed through matching of the threaded hole 901 and the screw 9.
Further, in order to avoid the collected bottom mud from escaping from the chute 601, a sealing sheet 11 is disposed below the connecting slide block 6, one end of the sealing sheet 11 is wound on a mounting shaft rod 10, the mounting shaft rod 10 is rotatably disposed below the connecting slide block 6 and the mounting shaft rod 10 extends along the width direction of the chute 601, the other end of the sealing sheet 11 is mounted at the lower end of the chute 601 through a clamping shaft rod 12, the clamping shaft rod 12 and the mounting shaft rod 10 are parallel to each other and located in the same vertical plane, the width of the sealing sheet 11 is equal to or slightly smaller than the width of the chute 601, and when the sampling tube 3 extends out of the limiting sleeve 1, the sealing sheet 11 is opened from the mounting shaft rod 10 to block the chute 601 between the mud scraping plate 5 and the end cover 301. A return spring is arranged on the mounting shaft 10, by means of which the mounting shaft 10 can be rotated in the direction in which the sealing disc 11 is wound.
