Portable underground water fixed-depth sampling device suitable for desert areas

Abstract

The invention discloses a portable underground water fixed-depth sampling device. The device comprises a base; a fixing frame is arranged on the outer wall of the top of the base; a rotating pipe is rotatably arranged on the fixing frame; a hose is connected to the outer wall of the rotating pipe in a wound mode; one end of the hose is communicated with the rotating pipe; a sampling mechanism is arranged at the other end of the hose; an adjusting wheel is arranged on the outer wall of one side of the rotating pipe; an air suction cylinder is arranged on the outer wall of the rotating pipe; theair suction cylinder is communicated with the rotating pipe through a communicating pipe; a control valve is arranged on the outer wall of the communicating pipe; a limiting mechanism is arranged onthe fixing frame; a supporting mechanism is arranged on the base; the sampling mechanism comprises a sampling barrel, a sliding rod, a piston plate, a collecting barrel and a rubber pad; and a mounting opening is formed in the outer wall of the top of the sampling barrel. In the process of moving the sampling barrel up and down, underground water of other depths is effectively prevented from immersing into the sampling barrel, so that fixed-depth sampling is effectively achieved, and a sampling effect is better.

Description

technical field [0001] The invention relates to the technical field of groundwater sampling, in particular to a portable groundwater depth-fixed sampling device suitable for desert areas. Background technique [0002] Groundwater refers to various forms of gravity water buried below the surface of the earth. As an important water body on the earth, groundwater has a close relationship with human society. The storage of groundwater is like forming a huge reservoir underground. With its stable water supply conditions, good It has become an important water source for agricultural irrigation, industrial and mining enterprises, and urban domestic water, and an essential water resource for human society. In recent decades, with the development of industry and agriculture, surface water resources have been difficult to meet in terms of quality and quantity. Social production needs, especially in arid areas, the development and utilization of groundwater resources are becoming more ...

Problems solved by technology

[0003] At present, in order to study groundwater, it is necessary to use a sampling device to sample the groundwater at a fixed depth. However, the existing sampling device still has certain shortcomings. When the sampling cylinder contacts the groundwater, the groundwater will directly enter the sampling cylinder, which cannot Layered sampling, and the physical and chemical properties and causes of groundwater at different depths are often different, mixed sampling affects the analysis results
