[0002] Rivers play a vital ecological role, but they also face environmental pollution and ecological threats. Eutrophication is a common problem in river water, and the protection of river ecosystems is receiving increasing attention. River sediments and water quality are interconnected, with various substances transforming between them. Conducting sediment surveys to understand the current state of river sediments and performing assessments lays an important foundation for further protection of the river ecosystem. A search of existing Chinese patents revealed a "riverbed silt sampler" with publication number "CN219810686U". This device separates the fixed iron mesh and sampling platform from the existing technology, thus ensuring that larger silt deposits can be sampled onto the sampling platform, guaranteeing the accuracy of the sampling results. However, during sampling, the bottom positioning base causes some sediment at the bottom of the river to be missed, affecting the accuracy of the sampling analysis. Utility Model Content

[0003] Therefore, it is necessary to provide a portable river sediment sampler to address the issue that the bottom positioning base may cause some sediment at the bottom of the river to be missed during sampling, thus affecting the accuracy of sampling analysis.

A sampling container is fixedly connected to the surface of the transverse partition. A plurality of vertical partitions are fixedly connected to the lower end of the transverse partition, and the vertical partitions are fixedly connected to the inner wall of the sampling container. The samples are distributed in a ring shape along the inner wall of the sampling container.

[0006] In one embodiment, the sealing assembly includes an operating rod fixedly connected to the lower end of an operating handle, a bottom sleeve sleeved on the outside of the operating rod, the bottom sleeve being fixedly connected to the lower end of a plug sleeve, and a plurality of connecting blocks being fixedly connected to the surface of the operating rod, wherein rubber blocks are fixedly connected to the surface of the plurality of connecting blocks.

[0007] In one embodiment, the upper end of the transverse partition is provided with a plurality of through holes, and a sealing cone is inserted into the inside of the through holes. The sealing cone is fixedly connected to the surface of the lower hard rubber abutment.

[0008] In one embodiment, a spring is provided at the upper end of the transverse partition, the spring is sleeved on the surface of the insertion sleeve, and a hard rubber abutment is fixedly connected to the end of the spring.

[0011] In one embodiment, a tapered guide block is fixedly connected to both the upper and lower ends of the rubber block, and the tapered guide block is fixedly connected to the surface of the connecting block.

[0012] Beneficial effects 1. The aforementioned portable river sediment sampler, through adjacent vertical partitions, guides river sediments between the adjacent vertical partitions when the sampling bucket is inserted into the riverbed. As the sediments enter the space between the vertical partitions, liquid is discharged to the outside through the through-hole at the upper end of the transverse partition. The spring abuts against the lower hard rubber abutment, causing the sealing cone to block the through-hole. At this time, the sediments are extracted between the adjacent vertical partitions, which can collect sediments from the bottom of the river and ensure the accuracy of sampling and analysis. 2. By manually rotating the operating handle downwards by 60 degrees, the conical guide block is moved to the area below the sediment to be extracted. Then, the conical guide block is moved upwards, which moves the rubber block to the area below the sediment. The rubber block forms a seal against the sediment. When the sampling bucket moves the sediment, it can seal the sample to prevent sample loss and ensure the stability of the sampling. Attached Figure Description

[0017] The portable river sediment sampler of this utility model is described below with reference to Figures 1-5.

[0018] In one embodiment, a portable river sediment sampler includes: an operating handle 1, with a plug sleeve 2 fitted over the outside of the operating handle 1; and a sampling mechanism 3, which is mounted on the lower end of the plug sleeve 2, with its surface extending to the end of the operating handle 1. The sampling mechanism 3 includes a sampling component 31 mounted on the surface of the plug sleeve 2, with its surface extending to the lower end of the plug sleeve 2. A sealing component 32 is disposed inside the sampling component 31, and the sealing component 32 is mounted on the lower end of the operating handle 1. As shown in Figures 1, 2, and 3, the sampling assembly 31 includes a transverse partition 312 fixedly connected to the lower surface of the insertion sleeve 2. A sampling container 311 is fixedly connected to the surface of the transverse partition 312. Multiple vertical partitions 313 are fixedly connected to the lower end of the sampling container 311. The vertical partitions 313 are fixedly connected to the inner wall of the sampling container 311. The multiple vertical partitions 313 are distributed in a ring along the inner wall of the sampling container 311. Multiple through holes 317 are opened at the upper end of the horizontal partition 312. A sealing cone 316 is inserted into the through hole 317. The sealing cone 316 is fixedly connected to the surface of the lower hard rubber support 315. A spring 314 is provided at the upper end of the transverse partition 312. The spring 314 is sleeved on the surface of the plug sleeve 2. A hard rubber bracket 315 is fixedly connected to the end of the spring 314. The upper hard rubber bracket 315 is fixedly connected to the surface of the plug sleeve 2, and the lower hard rubber bracket 315 is slidably connected to the surface of the plug sleeve 2. In this embodiment, the device guides river sediments between adjacent vertical partitions 313 when the sampling bucket 311 is inserted into the riverbed. As the sediments enter the space between the vertical partitions 313, liquid is discharged to the outside through the through hole 317 at the upper end of the transverse partition 312. When the sampling bucket 311 is lifted upwards, the spring 314 abuts against the lower hard rubber abutment 315, causing the sealing cone 316 to block the through hole 317. At this time, the sediments are extracted between the adjacent vertical partitions 313, improving the convenience of the sampling operation. like Figure 2 As shown in Figures 4 and 5, the sealing assembly 32 includes an operating rod 322 fixedly connected to the lower end of the operating handle 1. A bottom sleeve 321 is sleeved on the outside of the operating rod 322. The bottom sleeve 321 is fixedly connected to the lower end of the insertion sleeve 2. Multiple connecting blocks 324 are fixedly connected to the surface of the operating rod 322. Rubber blocks 326 are fixedly connected to the surface of the multiple connecting blocks 324. Multiple bottom grooves 323 are opened at the lower end of the bottom sleeve 321. The connecting blocks 324 are snapped into the inside of the bottom grooves 323. Conical guide blocks 325 are fixedly connected to the upper and lower ends of the rubber blocks 326. The conical guide blocks 325 are fixedly connected to the surface of the connecting blocks 324. In this embodiment, the device moves the conical guide block 325 to below the sediment by manually rotating the operating handle 1 downward by 60 degrees. Then, the conical guide block 325 moves upward, causing the rubber block 326 to move below the sediment. The rubber block 326 forms a seal on the sediment. When the sampling bucket 311 moves the sediment, it can seal the sample to prevent sample loss and ensure the stability of sampling. Working principle: When the sampling bucket 311 is inserted into the riverbed, the adjacent vertical baffles 313 guide the river sediment to the space between them. Liquid is discharged to the outside through the through-hole 317 at the upper end of the transverse baffle 312. When the sampling bucket 311 is lifted upwards, the spring 314 abuts against the lower hard rubber support 315. The movable sealing cone 316 blocks the through hole 317. The manual rotating operating handle 1 moves it down by 60 degrees, and the conical guide block 325 moves to below the extracted sediment. Then, the conical guide block 325 moves up, driving the rubber block 326 to move to below the sediment, and the rubber block 326 blocks the sediment.
