Underground water level metering device

Abstract

The invention discloses an underground water level metering device. The device comprises an undamped pulley arranged on a pulley base, a measuring rope is hung on the undamped pulley, a buoy is tied to one end of the measuring rope, a weight is tied to the other end of the measuring rope, monitoring points are arranged on the surface of the measuring rope at equal intervals, a monitor is arranged above the undamped pulley and connected with a controller, and the monitor reads changes of the monitoring points on the measuring rope to calculate the change value of the water level. The undamped pulley is coaxially provided with a micro driven wheel, a minimal damper is disposed between the micro driven wheel and the undamped pulley, a cycloid pin is arranged on the micro driven wheel, and the two sides of the cycloid pin are provided with a forward blocking piece and a reversing blocking piece respectively. When the cycloid pin touches the forward blocking piece, negative signals are transmitted to the controller, otherwise, the negative signals are transmitted to the controller, the controller judges whether the undamped pulley rotates clockwise or anticlockwise according to positive signals or negative signals, and accordingly whether the water level is raised or decreased is judged. The device can be used for automatically monitoring the underground water level for a long time.

Description

technical field [0001] The invention belongs to the technical field of water level measurement, in particular to a water level measurement device, in particular to a groundwater level measurement device. Background technique [0002] Water is a natural resource that human beings rely on for survival and development, and it is even more precious today when water resources are increasingly scarce. Among them, groundwater, as an important water supply source, plays an important role in human life, national economic construction and social development in drinking, municipal administration, industry, agriculture and other aspects. The important purpose of investigating the objective laws of groundwater distribution and formation is first of all how to rationally develop and sustainably utilize groundwater resources. In places where groundwater resources are poor, all we need to do is to find groundwater. However, in places where groundwater resources are abundant, what we need t...

Problems solved by technology

These two methods are very inconvenient in actual use, and the measured values ​​are not accurate enough due to the influence of external environmental factors

For example, in the underground humid environment, the electrode is easily triggered by the wet environment, resulting in inaccurate measurement; while the bell listening method requires the water well to be straight, which is difficult to achieve in some environments, and the curved water well is not suitable. use the bell method

Moreover, both methods require the monitoring personnel to have a lot of experience. The most important thing is that these two methods require the monitoring personnel to repeat the measurement many times, and cannot realize real-time monitoring.
