Abstract

The invention discloses a sediment sampling device for a water conservancy project, which comprises a traction assembly and a sampler, wherein the overall shape of the sampler is in a boat anchor shape, the traction assembly is used for driving the sampler to ascend and descend, the sampler is composed of an anchor rod and a soil sampling plate, the left end of the anchor rod is connected with a soil entering rope, and the outer portion of the right end of the anchor rod is connected with an anchor weighing rope; the traction assembly comprises a winding roller used for winding and unwinding the soil entering rope and the anchor weighing rope. According to the sediment sampling device for the water conservancy project, the principle of a rudder is utilized, a soil entering rope is utilized to pull an anchor rod, a soil taking plate can be inserted into soil, sediment can enter a storage cavity from a soil entering opening, the limitation of the length of a pipe body of connecting rod drilling is broken through, and the sediment in a deeper water area can be sampled; meanwhile, what is guaranteed is that sediment automatically enters the storage cavity, excessive water mixing is avoided, the integrity of sediment samples is guaranteed, in the sampling process, the storage cavity can be dredged, blockage is prevented, and deepwater sediment sampling is achieved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering detection, in particular to a sediment sampling device for water conservancy engineering. Background technique [0002] Water conservancy engineering is a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. Reservoir is also a kind of water conservancy project. After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply, power generation, and fish farming. [0003] In order to better protect water sources and fish farming, etc., it is necessary to regularly sample and test the water quality of the reservoir and the sediment at the bottom. [0004] Most of the existing sediment sampling devices are connecting rod drilling type and pipeline pumping type. When working in reservoirs, the water area is often deep. The connectin...
