Description

Technical Field

[0002] Water level measurement is a key operation in a water supply plant. By monitoring the water levels of source wells and booster wells, it is possible to ensure that there is sufficient water supply and avoid water shortages due to low water levels.

[0003] The Chinese utility model patent with authorization announcement number CN207556618U discloses a new portable water level and depth measuring device that does not get stuck in the well, including a measuring line, which is two independent insulated wires. One end of the measuring line is wound on a winding reel, and the end extends out of the winding reel and is connected to the positive and negative poles of the multimeter. The middle part of the measuring line passes around a handheld roller, and the tail end of the measuring line is connected to a plumb bob. The plumb bob is two independent steel balls arranged up and down, wherein the upper steel ball is provided with through holes along its radial direction, and the metal core of one of the two insulated wires is fixed on the upper steel ball, and after the other insulated wire passes through the through hole of the upper steel ball, its metal core is fixed on the lower steel ball. However, each booster well in the water supply plant uses a submersible pump to pump water out of the well. Most of the space in the well is occupied by pump pipes and cables, and the available space in the well is relatively small. When two measuring ropes are used to measure the water level, the measuring ropes are prone to entanglement or getting stuck in the well. In addition, the measuring ropes need to be lowered manually and the water level in the well needs to be read by the marks on the measuring ropes. After the measurement is completed, the measuring ropes need to be manually retrieved, which is labor-intensive and inefficient. Summary of the invention
