Groundwater source detector is a kind of equipment used to find groundwater source, its advantages and principles mainly involve the instrument principle and natural electric field two aspects.
I. Principle of Instrument
Groundwater source detector is mainly composed of transmitter and receiver. The transmitter sends out electromagnetic or acoustic signals, which will be interfered by the groundwater in the process of underground propagation, and the receiver receives these interfered signals and analyzes them. According to the signal propagation time, amplitude and frequency changes and other parameters, the existence and location of groundwater can be inferred.
Second, the natural electric field
Natural electric field is one of the main reliance of groundwater source detectors. There are various electric fields on the surface of the earth, including natural electric field, artificial electric field and electromagnetic field. Among them, the natural electric field is formed by the charged particles on the surface of the earth, the ionosphere of the atmosphere and the earth's magnetic field and other factors. Groundwater source detector can quickly and accurately determine the location and depth of groundwater by utilizing the changing characteristics of natural electric field in the presence of groundwater.
Third, the advantages of comparison
Groundwater source detector has the following advantages compared with other water source detection methods:
Wide range of application: the groundwater source detector is applicable to different terrain and climatic conditions, such as desert, grassland, mountainous areas and so on.
Fast speed: Underground water source detectors can find water sources quickly, saving time and labor costs.
High precision: the underground water source detector can determine the location and depth of underground water with high precision through advanced signal processing technology.
Strong sustainability: the underground water source detector does not need to consume a lot of energy and water resources, and is characterized by sustainable development.
IV. Application Prospects
With the continuous progress of technology, the application prospect of groundwater source detector is more and more broad. Globally, with the increasing shortage of water resources, it becomes more and more important to find and develop new water sources. Groundwater source detectors can not only be used for human and animal drinking water and agricultural irrigation, but also be applied in the fields of urban water supply and industrial water. At the same time, with the deep development of earth science research, groundwater source detectors will also play an important role in the fields of geological exploration, mineral resources development and environmental protection.
