Pond sludge sampler

Abstract

The invention discloses a pond sludge sampler which is sampling equipment for sludge at the bottom of a pond. The sampler comprises a drill component and a drill stem component which are connected with each other through a sampling pipe in the drill stem component; a square plate of the drill component is fixed in the middle of a shell of a drill, a hinge plate is fixed on the square plate, a steel wire is used for connecting the hinge plate and the sampling pipe, an inner ring of an inner film of the sampling pipe is arranged at a lower end ring opening of the shell of the drill; the sampling pipe of the drill stem component is connected with the drill component through a clamping ring, and the other end of the sampling pipe is in threaded connection with a combining pipe and an extension pipe, one end of the inner film of the sampling pipe is fixed on the drill shell through the inner ring of the sampling pipe, a film body is arranged in the sampling pipe, the combining pipe and the extension pipe. The tool disclosed by the invention not only can be used for fast collecting the sludge at the bottom of the pond, but also has the advantages of being simple in operation, convenient to sample, capable of completely storing a bedding architecture of the sludge, and the like.

Description

technical field [0001] The invention relates to a sampling device for pond bottom mud, in particular to a pond mud sampler. Background technique [0002] The sediments of ponds and reservoirs record various terrestrial ecological environment indicators such as temperature, humidity, soil erosion, nutrients, pollutants, and biodiversity. The collection of pond silt is a necessary means to extract pond sediments and is widely used in environmental protection. Field of analysis and scientific research. At present, the collection methods of pond silt mainly include grab type and cylinder type. The collection of pond silt is different from the collection of surface soil, bedrock or ice core. The texture of pond silt is soft, with high moisture content, fluidity and viscosity strong. Traditional sampling methods often have too complicated structures, or the collected samples are not easy to take out, the sampling depth is generally shallow, and the collected silt is easy to adhe...

AI Technical Summary

Problems solved by technology

Traditional sampling methods often have too complicated structures, or the collected samples are not easy to take out, the sampling depth is generally shallow, and the collected silt is easy to adhere to the surface of the instrument. Preserving the bedding structure of the sludge sample, and the cleaning of the instrument requires a lot of labor and water resources, and the sampling efficiency is relatively low. There are many limitations in the actual application process, and often cannot meet the requirements of experiments and analysis.
