Description

Integrated and portable groundwater level measuring device

Technical Field

The utility model belongs to the technical field of groundwater monitoring, and particularly relates to an integrated and portable groundwater level measuring device.

Background

Groundwater refers to water that is present in rock voids below the ground, and in a narrow sense refers to water in saturated aquifers below the groundwater level. In the national standard hydrogeological terminology (GB/T14157-93), groundwater refers to various forms of gravitational water buried below the surface of the earth. Groundwater level measurement is one of the basic works of normalization for groundwater monitoring in departments such as water conservancy, environment, geology, traffic, agriculture, etc. At present, the underground water level measurement is usually that a technician throws a measuring instrument into water from a monitoring well and a wellhead of a water well, the mode can cause disturbance to the water body, measurement can be carried out after a period of time, and the measuring instrument is easy to collide on the inner wall of the well when throwing and lifting up for recovery, and particularly for a monitoring well with a smaller wellhead, the instrument is easy to damage. If the manual work is slowly lowered, the problem of easy shaking also exists, and for manual lowering and recycling, a certain potential safety hazard exists because technicians are close to the wellhead and even directly cross over the wellhead. Although water level monitors capable of automatically lifting are also on the market at present, the water level monitors are inconvenient to carry, are sometimes monitored for a long time after being installed, and cannot meet the working requirements of moving measuring equipment along with detection and along with walking and more detection tasks. For this reason, it is necessary to develop a groundwater level measuring device which is portable and capable of automatically lowering or stowing a water level measuring sensor.
