Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a portable device for taking silt samples underwater. Background Art

[0002] Obtaining undisturbed underwater mud samples is crucial for water quality monitoring, sediment research, and environmental assessments. Existing sampling devices are often complex and difficult to carry, or they can easily disturb the sample during the sampling process, affecting data accuracy. Therefore, developing a device that is both portable and efficient for collecting mud samples is imperative.

Before the device is operated, the sliding block is located at the left end of the extraction box. Opening the solenoid valve allows the sludge in the extraction box to flow into the collection bottle through the discharge pipe. After collection is completed, the extraction rod is used to push the sliding block forward to discharge excess sludge in the extraction box, thereby preventing excess sludge from accumulating inside the device and achieving preliminary cleaning inside the device, reducing the workload for subsequent cleaning work, and is suitable for large-scale promotion.

[0004] Although the equipment in the above-mentioned literature can be easily moved, the equipment has a relatively simple structure, and the collection of sludge is still not convenient. In addition, the supporting structure is not stable enough, and the treatment effect of the extracted sludge is not good, which greatly reduces the practical value of the equipment.
