Description

Technical Field

[0001] This utility model relates to the field of data collection device technology, specifically a data collection device for sediment samples from silt-collecting dams. Background Technology

[0002] The sediment sampling device for silt-retaining dams is mainly used for monitoring soil and water conservation, studying ecological evolution, and investigating siltation conditions. It is used to obtain sediment samples within the silt-retaining dams, providing support for analyzing sedimentation-related data and evaluating the soil and water conservation benefits of silt-retaining dams.

[0003] Utility model patent CN222439189U discloses a river sediment sampling device, relating to the field of river sediment sampling technology. It addresses the challenges of sampling low-lying river sediment, where the container's opening makes the sediment easily washed away by the water flow, hindering its removal. Furthermore, sampling deeper sediment requires tilting and shoveling, leading to stricter requirements on the length and maneuverability of the sampling device. The device features a connecting rod in the middle, with a lifting rod rotatably connected to its bottom. The connecting rod has threaded grooves on its sidewalls, and sampling components are connected to the bottom of the lifting rod. These components are arranged in a cross configuration, swinging and opening / closing along the intersection points. This device allows for convenient sampling of sediment from the riverbed and enables vertical control of the shoveling motion, facilitating the removal of deeper sediment.

[0004] In the aforementioned prior art, the irregularly shaped bottom of the sampling device makes it inconvenient to insert it into deep sediment for sampling, hindering the collection of sediment samples at different depths. Therefore, improvements are needed. Utility Model Content

[0025] The specific implementation process of this utility model is as follows: In use, first insert the insertion rod 2 into the mud and sand, then step on the support block 6.

The handle 82 drives the pressure rod 81 and the square rod 87 to move down. The pressure rod 81 will drive the connecting block 83 to slide along the fixed rod 84 and press down the first spring 85. The square rod 87 drives the connecting rod 91, the partition 93 and the insertion rod 2 to move down, so that the insertion rod 2 is separated from the fixed seat 1. At this time, the mud and sand will be collected through the gap between the insertion rod 2 and the fixed seat 1 into the interior of the insertion rod 2. This can achieve the purpose of collecting mud and sand at different depths.

[0026] When sediment needs to be recovered, simply rotate the insertion rod 2. The insertion rod 2 drives the partition 93, connecting rod 91, and connecting column 92 to rotate, causing the connecting column 92 to make a threaded movement inside the square rod 87, eventually separating the connecting column 92 from the square rod 87. At this time, under the elastic action of the compressed second spring 96 inside the connecting sleeve 95, an upward thrust is given to the connecting rod 94. The connecting rod 94 drives the ball 97 to slide along the slide groove 98, and the connecting rod 94 pushes the partition 93 upward, which can push the collected sediment out of the insertion rod 2, making it convenient to recover and remove the collected sample.
