Title:
SELF-ANCHORING POST-TYPE SEDIMENT SAMPLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/035743
Kind Code:
A1
Abstract:
The invention relates to the technical field of environmental monitoring, environmental management, and sediment sampling, and specifically, to a self-anchoring post-type sediment sampling device. The device mainly comprises a sampling pipe mechanism (3), an anchor frame mechanism (1) and a cable (4). A drainage device is configured to automatically drain water and seal air, to enable a favorable anchoring condition on the sediment when sampling, combined with an adjustable weight so as to provide a stable sampling condition. The drainage device is also applied in the sampling pipe mechanism (3) to facilitate sampling and sealing of a sediment sample. Upon completion of sampling, a water injection device is configured to remove a suction force to the sediment, and reduce a resistance force during a pulling process. A pulley A and a hook (1-8) are arranged on the cable (4) via a fixing rod (1-9), and a pulley B is fixed on an outer sampling pipe (1-3). The embodiment converts a pull force into a pressure to the sampling pipe so as to provide a power for sampling, thereby implementing sampling of a stratified sediment sample. The sampling device has features of being compact, having high performance and favorable fidelity, and being suitable to sample stratified sediment from a water zone such as a dam, having a high water level and soft bottom portion.
