Pneumatically protected anti-impurity groundwater sampling and detecting device

Abstract

The invention discloses a pneumatically protected anti-impurity groundwater sampling and detecting device, which comprises a mounting plate, a bobbin, a water inlet hose, a water collecting head and adetecting structure, wherein a mounting hole passes through the central part of the mounting plate; an air outlet pipe and a liquid outlet pipe are symmetrically connected with the two ends of the bobbin the water inlet hose is wound around the bobbin; one end of the water inlet hose is in communication with the bobbin; the water inlet hose is in communication with the water collecting head at the end away from the bobbin; and the bobbin is rotated by the air outlet pipe and the liquid outlet pipe which pass through to the side wall of the mounting hole and are rotatably connected. The watercollecting head is opened or closed pneumatically during the sinking process of the water collecting head, thereby preventing the blockage of sludge impurities in the water from affecting the collection of a water sample and improving the collection precision. The water inlet hose is driven by a motor to be wound or released so as to control the lifting and lowering of the water collecting head, thereby contributing to the control of the depth of water collection to achieve water collection at any depth.

AI Technical Summary

Benefits of technology

This technology helps regulate the movement of an object's position within its housing while collecting samples from different locations on-the-go. By controlling how much pressure (pressure) needs to occur before the water starts draining back up inside the device, this allows accurate measurements over longer periods without having to stop working altogether. Additionally, there are benefits such as prevention of clogging caused by debris particles entering pipelines due to their size being too small compared to larger objects like rocks). Overall, these technical features help make sampling more efficient and effective across various applications where water quality monitoring becomes necessary.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving accuracy during sampling for analyzing soil-based waters from various sources like wellbores drilled through oil fields containing high levels of dissolved solids (such as calcium) found near populated areas where there may be heavy rain events affecting drinkable supplies used throughout life. Current methods involve extending an extra tool inside the collected water before analysis can take place but these tools often get stuck with sediment causing incorrect results.
