[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0020] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0021] like Figure 1 As shown, a preferred embodiment of an underwater sediment sampler device for hydrological testing is presented, which includes: a connecting rod 1, a cover plate 2, and a spring 3.

[0022] The upper outer wall of the connecting rod 1 is provided with an external thread 4; the lower part of the connecting rod 1 extends into the sampling part 5 and is installed inside it; the cover plate 2 and the spring 3 are both sleeved on the connecting rod 1, and several nuts are installed on the external thread of the connecting rod 1. The top end of the spring 3 can abut against a nut, and the bottom end of the spring 3 can abut against the cover plate 2.

[0023] In actual use, when the sample needs to be loaded into the sampling section 5, the cover plate 2 should be opened so that the cover plate 2 is away from the sampling section 5. Then the sample is loaded into the sampling section 5. After the sampling section 5 has completed sampling, the spring force 3 makes the cover plate 2 able to block the sampling section 5, thereby preventing the bottom sediment sample from being washed away by the water flow when the sample is taken out of the water.

[0024] Specifically, the external thread 4 occupies 1 / 3 of the length of the connecting rod 1. The connecting rod 1 and the sampling part 5 are metal structures of the same material. The sampling part 5 has a diameter of 200mm, a height of 200mm, and a wall thickness of 2-3mm.

[0025] Based on the above, this utility model also has the following embodiments:

[0026] Furthermore, a hydrological underwater sediment sampler device further includes: a insertion rod 6; a connecting rod 1 has an insertion hole, and the insertion rod 6 is inserted into the insertion hole. Specifically, the insertion hole is located at 1 / 3 of the distance from the connecting rod 1 towards the sampling section 5, and the diameter of the insertion hole is... When the cover plate 2 is opened so that it is away from the sampling part 5, the cover plate 2 can be pushed above the insertion hole, and then the insertion rod 6 can be inserted into the insertion hole to fix the cover plate 2 away from the sampling part 5.

[0027] Furthermore, in a hydrological survey underwater sediment sampler device, the sampling section 5 is cone-shaped and hollow, with an opening 8 through which a connecting rod 1 extends into the interior of the sampling section 5. Specifically, the cone-shaped portion of the sampling section 5 faces away from the connecting rod 1, facilitating insertion of the sampling section 5 into the sampling position during sampling.

[0028] Furthermore, a hydrological underwater sediment sampler device further includes: a gasket 9; the gasket 9 is sleeved on the connecting rod 1, and the gasket 9 is connected to the top of the spring 3. Specifically, when the spring is in the relaxed state, it is the same length as 2 / 3 of the connecting rod 1, and the spring 3 can press the cover plate 2 against the upper part of the sampling section 5 to seal the sampling section 5.

[0029] Furthermore, in a hydrological survey underwater sediment sampler device, the area of ​​the cover plate 2 is larger than the area of ​​the opening 8. Specifically, the cover plate 2 can seal the sampling section 5.

[0030] Furthermore, in a hydrological survey underwater sediment sampler device, the connecting rod 1 and the sampling part 5 are installed by welding.

[0031] Further, the number of nuts 7 is at least two. Specifically, one nut 7 can be used to push the spring 3 downwards, so that the cover plate 2 is pushed downwards by the elastic force of the spring 7, and the other nut 7 plays a role of preventing falling off.

[0032] The above merely describes the preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made according to the content of the present application description and drawings should be included in the protection scope of the present application.
