Convenient apparatus for sampling water bodies having different depths from underground/surface water, and method thereof

Abstract

The invention discloses a convenient apparatus for sampling water bodies having different depths from underground/surface water, and a method thereof. The apparatus comprises a telescopic connecting rod, and the bottom of the telescopic connecting rod is provided with a plurality of detachable sampling bottles; a reel is arranged at the fixed end at the top of the telescopic connecting rod, and a wheel skidding fixed device is arranged at the extension end at the bottom of the telescopic connecting rod; a plurality of rails are respectively arranged on the reel and the wheel skidding fixed device, a lifting rope is wound on every rail, and the quantity of the lifting ropes is same to that of the sampling bottles; and the top of every sampling bottle is provided with a sampling bottle cap and a check valve device, and the bottom of the lifting ropes are respectively connected with the check valves. The sampling apparatus is placed in the water, the lifting ropes corresponding to the sampling bottles are respectively stretched, and the corresponding check valve devices are opened to collect the water bodies. The apparatus and the method have the advantages of manpower saving, great reduction of the interference of disturbance of the water bodies, caused by repeated water collection in the sampling process, to the components of the water bodies, and provision of a strong technical foundation for the water environment investigation work.

Description

technical field [0001] The invention relates to the fields of environmental water quality monitoring technology and hydrological measurement, in particular to a portable underground / surface water sampling device for water bodies at different depths. Background technique [0002] Ground / surface water sampling technology is one of the key technologies to obtain chemical and physical indicators of water, and occupies an important position in water environment research. As the problem of water pollution becomes more and more severe, domestic and foreign scientific researchers attach great importance to underground / surface water sampling technology and have developed a series of sampling devices. It is suitable for different requirements of sampling in different environments. The classification is mainly based on the water depth of sampling and the sampling frequency. [0003] The existing underground / surface water sampling methods are mainly divided into three types: the first...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a convenient underground / surface water sampling device for different depths of water in view of the lack of automatic sampling devices when collecting water bodies of different depths at the same point in the prior art
