Sampling device for hydrological monitoring sample

Abstract

The invention discloses a sampling device for a hydrological monitoring sample. The sampling device comprises a sampling cylinder, the sampling cylinder is provided with symmetrically arranged fan-shaped sliding grooves, the fan-shaped sliding grooves are located in the middle of the sampling cylinder and are communicated with the interior of the sampling cylinder, and the sampling cylinder is provided with a first sampling hole and a second sampling hole which are communicated with the interior of the sampling cylinder. The first sampling hole is located in the middle of the sampling cylinder, the second sampling hole is located in the lower end of the sampling cylinder, a fixing part is arranged in the sampling cylinder, a through hole is formed in the middle of the fixing part, and a fan-shaped block is arranged in the fan-shaped sliding groove. The device comprises a rotating part, a floating body, a sampler, a connecting pipe and a sampling pipe. The sampling device is novel in structure, ingenious in design, small and exquisite, can adapt to different external environments, and cannot be affected by severe environments, for example, the sampling device can overcome the problems that when no electricity exists, rivers and lakes are deep, the rivers and the lakes are difficult to submerge in deep positions for sampling and the like.

Description

technical field [0001] The invention relates to the technical field of hydrological monitoring sampling devices, in particular to a sampling device for hydrological monitoring samples. Background technique [0002] Hydrological monitoring refers to a complex and comprehensive systematic project that monitors, measures, analyzes and early-warning the temporal and spatial distribution and change rules of natural water through scientific methods. The hydrological monitoring system is suitable for hydrological departments to monitor rivers, lakes, reservoirs, Real-time monitoring of hydrological parameters such as channels and groundwater. The monitoring content includes: water level, flow, flow velocity, rainfall (snow), evaporation, sediment, ice, moisture, water quality, etc. [0003] In the current sampling process of hydrological monitoring, many of the water bodies are sampled by hand-held containers, which usually need to be manually entered into the water body.

Problems solved by technology

[0003] In the current sampling process of hydrological monitoring, many of the water bodies are sampled by hand-held containers, which usually need to be manually entered into the water body. The depth is often uncontrollable, and it is difficult to ensure the accuracy of sampling water bodies

At the same time, the river bed loosening collection mechanism used raises the soil at the bottom of the water, but this structure cannot reach the lower end of the soil to collect the muddy water raised by the deeper wet soil, which limits the sampling of hydrological monitoring and leads to Complete water source information cannot be obtained after the water source inspection, which makes the water source information there flawed, which will affect the later investigation work

And the device also needs to be driven by a power supply, and there is no power supply in a relatively harsh environment, which leads to the limitation of sampling of the device

At the same time, the use of automated operations is also prone to untrue sample data and uncertainty
