Description

Fixed-point water sampling device for groundwater environmental investigation

Technical Field

The utility model relates to the technical field of water sampling devices, in particular to a fixed-point water sampling device for groundwater environment investigation.

Background Art

Groundwater refers to water that exists in the rock voids below the ground. In a narrow sense, it refers to water in saturated aquifers below the groundwater surface. Foreign scholars believe that there are three definitions of groundwater: one is all water buried in groundwater that is significantly different from surface water, especially the part of water in the saturated zone of the aquifer; the second is water that flows or infiltrates downward, saturates the soil and rocks, and replenishes springs and wells; the third is water stored in underground rock cavities and in the voids that make up the crust. Groundwater is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining and cities. Groundwater environmental surveys generally use impact drills to construct wells, and then use bailer pipes to collect water so as to directly collect groundwater. The existing fixed-point water collection device for groundwater environmental surveys requires staff to rotate the drill tube and move it downward for sampling.

The existing Chinese patent (Announcement No.: CN217006515U) discloses a fixed-point water sampling device for groundwater environmental investigation, which relates to the technical field of groundwater exploration equipment. In view of the problem that the existing fixed-point water sampling device for groundwater environmental investigation is inconvenient to operate, and when taking groundwater at a specific depth, it is easy to mix with groundwater at other depths, which affects the water quality detection results, the following scheme is proposed, which includes a bottom plate and a rotating rod, the top of the bottom plate is fixedly installed with symmetrically distributed columns, a top plate is fixedly installed between the tops of the two columns, an electric hydraulic rod is fixedly installed at the bottom of the top plate, a moving plate is slidably installed between the two columns, the rotating rod is rotatably installed at the bottom of the moving plate, and a support frame is fixedly installed at the top of the moving plate. The utility model can facilitate the staff to conduct groundwater exploration and sampling, and can take groundwater samples at a specific depth to prevent mixing with groundwater samples at other depths, thereby ensuring the accuracy of the water quality detection results after sampling.

When the existing fixed-point water collection device is in use, it is necessary to pump up the groundwater and then store it. The storage is not timely enough, and it is not convenient to take out the pumped water, which reduces the performance of the device.

Based on this, the utility model designs a fixed-point water sampling device for groundwater environment investigation to solve the above problems.

As an optional embodiment, a plurality of through holes 14 are opened on the side of the drill pipe 11 near the lower end, and a filter plate 15 is fixedly installed inside the through hole 14. The plurality of through holes 14 are equidistantly distributed in a ring shape, and the filter plate 15 prevents sand in the stratum from entering the water extraction device.

As an optional embodiment, a water suction pipe is fixedly installed in the middle position of the lower end surface of the water storage barrel 12, and the outer wall of the water storage barrel 12 is close to the inner wall of the drill rod 11, ensuring that the position of the through hole 14 is blocked during the descent of the drill rod 11 to prevent water at other positions from entering the interior of the drill rod 11.

As an optional embodiment, a positioning plate is fixedly installed on the upper end surface of the electric push rod 3, and the positioning plate is rotatably connected to the frame 2. When the drill rod 11 rotates and descends, it can drive the electric push rod 3 to rotate together to prevent it from hindering the descent of the drill rod 11.

A specific application of this embodiment is as follows: first, the base 1 is installed at the position where groundwater needs to be collected, and the driving motor 4 is started to drive the active gear 6 on the rotating shaft 5 to rotate, thereby driving the driven gear 7 to rotate.
