Pollutant sampling device for water environment engineering detection

Abstract

The invention relates to the technical field of sampling devices, in particular to a pollutant sampling device for water environment engineering detection.The pollutant sampling device comprises a sampling barrel, the bottom of the sampling barrel is connected with a bottom plate through a connecting assembly, the top of the sampling barrel is provided with a cover plate, the top of the cover plate is provided with a lifting assembly, and a handle is arranged above the sampling barrel; the handle is connected with the sampling barrel through an adjusting assembly; the adjusting assembly comprises nuts, the nuts are installed on the two sides of the outer portion of the sampling barrel, a handle is arranged at the top of the sampling barrel, one end of each screw penetrates through the handle to be in threaded connection with the corresponding nut, and the two screws are connected through a belt wheel transmission assembly. The problem that when water sources with different depths are sampled, sampling equipment is mostly placed in water through ropes, stratified sampling is carried out on the water sources, and the accuracy is reduced is effectively solved.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a pollutant sampling device for water environment engineering testing. Background technique [0002] The water environment is one of the basic elements of the environment. It is an important place for the survival and development of human society, and it is also the most severely disturbed and damaged area by humans. The pollution and destruction of the water environment has become one of the major environmental problems in the world today. , with the continuous development of industry, water pollution is becoming more and more serious. In order to ensure the safety of water sources, the detection of water sources has become particularly important. When detecting water sources, it is necessary to use a sampling device to first sample the water source, and then in the Detect pollutants in water sources through detection equipment; [0003] In the process of sampling and ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of pollutant sampling device that is used for water environment engineering detection, to solve the existing pollutant sampling device proposed in the above-mentioned background technology when sampling the water sources of different depths, most of them use ropes to The sampling equipment is placed in the water, and the water source is sampled in layers, but because the rope is easy to float in the water, it reduces the accuracy of the deep sampling of the water source.
